Introduction
As we all know, slip rings are devices used to transmit electrical signals and power between the rotating and stationary parts of equipment. They are used in equipment such as robots, medical devices, packaging machinery and conveying system. Among them, Rotary filling machine, labeling machine, capsule packaging machine, and high-speed granule packaging machine are common examples. For these devices, slip rings assist them in completing operation instructions in processes such as filling, wrapping, sealing, and stacking.
Stretch wrapper machine is a common agricultural machinery. It uses plastic film to wrap hay, straw, or silage bales to preserve feed. The machine can be semi-automatic or fully automatic and has various designs, including turntable type, rotating arm type, and horizontal type. During transportation, the film cutting and packaging system folds up to avoid being in the way. It also picks up and transports pallets by fork racks. And all these operations require the use of slip rings.
During the packaging process, the slip ring is responsible for power transmission and instruction transfer between the motor and different components to achieve 360-degree rotary packaging. So, do you know how all this is achieved? Today, ByTune will take you to explore the usage details of slip rings in stretch wrapper machines.
Main Applications of Slip Rings on Stretch Wrapper Machines
Slip rings are used between many different parts of the stretch wrapper machine. They transmit power and signals to these parts, enabling them to receive instructions in a timely manner and automatically complete operations such as running and packaging. The specific application situations are as follows:
Rotating Table Part
The rotating table of the stretch wrapper machine is a part that carries haystacks and hay bales and rotates to wrap the film. The slip ring is usually installed at its rotating shaft. Among them, the conductive ring of the slip ring is connected to the power line of the machine, and the brush is in contact with the rotating joint of the rotating table. After the machine is started, the rotating table needs a driving device to make it rotate. Usually, it is a driving system composed of a motor, a reducer, a transmission belt or a chain. The motor provides power, and the slip ring can transmit this power so that the turntable can rotate at a set speed and direction, such as 30 revolutions per minute.
Stretching Device Part
The main function of the stretching device is to stretch the plastic film. Through the mechanical structure and power system, the film is pulled out from the film roll and stretched according to the set stretching ratio. For example, the stretching of the film is achieved by using different speeds between a set of cooperating rollers. The stretched film can better wrap objects such as hay and silage bales, making the package tighter.
The stretching device is usually fixed on the packaging machine or works in coordination with the rotating table. The focus is on the stretching treatment of the film, rather than flexibly adjusting the spatial position like a robotic arm. The slip ring is responsible for transmitting control signals. Therefore, you can set parameters such as the stretching ratio and the number of winding layers of the film through the control panel. These parameter signals are transmitted to the stretching device and related actuators through the slip ring, so that the equipment performs the film winding operation according it.
Robotic Arm Structure
The robotic arm is a mechanical structure with multiple joints and degrees of freedom. Its main function is to change position and posture to adapt to haystacks and feed bales of different shapes, sizes and stacking methods. It can rotate, extend and bend in three-dimensional space, and accurately cover the film on all parts of the feed bale, especially for some irregularly shaped objects.
In addition, it can carry the film stretching device, or it can simply be used for handling and positioning the film, or assisting the action of wrapping the film around an object. When it needs to adjust its posture according to the shape and position of an item, the signal sent by the control system is transmitted to each joint motor of the robotic arm through the slip ring, so that the robotic arm can accurately complete the action.
Benefits of Using Slip Rings on Stretch Wrapper Machines
Using slip rings in stretch wrapper machines to help control the speed and operational accuracy of the packaging process has many benefits, as follows:
Continuous Power Supply
Components such as the rotating table and robotic arm of the stretch wrapper machine require continuous power supply to maintain operation. During the busy farming season, these components need to operate for a long time. Slip rings can maintain stable transmission of current between the motor and these components. Therefore, the packaging work of feed and hay can be carried out continuously. Assuming there is no slip ring, the power supply line of the rotating part may be twisted and tangled due to continuous rotation, and ultimately reduce the packaging efficiency by about 30% - 40%.
Accurate Instruction Data
During the packaging and advancing process of the haystack packaging machine, various control signals such as sensor signals and encoder signals need to be transmitted. Slip rings can transmit these signals with extremely low loss levels, helping the machine's control system monitor and adjust the packaging process. For example, after the sensor detects information such as the size and position of the haystack, the signal is transmitted to the control system through the slip ring. The control system then controls the actions of components such as the stretching device and the film cutting system according to this information. And these can greatly reduce problems such as packaging size deviation and uneven film cutting.
Reduce Maintenance
The emergence of slip rings allows us to avoid using cumbersome connecting wires. These wires are easily twisted and rubbed during rotation and may knot and cause the machine to stop. Compared to it, slip rings can reduce equipment maintenance and downtime, especially during the busy farming season. In addition, this kind of packaging machine generally works in an outdoor environment with a lot of dust around. Due to its sealed structure, the slip ring can prevent dust, moisture, etc. from entering the interior and ensure its normal operation.
360-Degree Unrestricted Rotation
Slip rings allow the rotating parts of stretch wrapper machines to rotate 360 degrees without restriction. The packaging machine can be more flexibly adapted to hay packaging operations of different shapes and sizes. For example, the film can be uniformly and comprehensively wrapped around the haystack so that it will not scatter during transportation.
Quick Parameter Adjustment
During the packaging process, we may need to adjust packaging parameters according to different situations of the haystack, such as the stretching degree of the film and the winding speed. Slip rings can quickly transmit these parameter adjustment signals to the control system. Through current transmission with the motor, it drives components such as the rotating table to operate with new settings, thereby further improving production efficiency.
Factors to Consider When Choosing Slip Rings for Stretch Wrapper Machines
When purchasing slip rings for stretch wrapper machines, the following factors and parameters need to be considered:
• Working Voltage: Determine the working voltage of the slip ring according to the requirements of the packaging machine's electrical system. This is to ensure that the slip ring can work normally within the voltage range of the equipment. Among them, common working voltages of slip rings are 24V, 36V, 48V, etc. Special equipment may require higher or lower voltages. A certain voltage margin should be left when choosing to cope with situations such as voltage fluctuations.
• Number of Circuits: The control systems of most fully - automatic stretch wrapper machines are relatively complex and need to transmit control signals of multiple sensors and actuators. They require more current channels. For example, ByTune's BTH2586 Customized Slip Rings for Wrapper Machines. It supports 24, 30, or 48 - channel designs and can easily and centrally transmit different types of signals to guide the wrapping and cutting operations of the packaging machine.
• Working Current: The current parameter determines the choice of the conductive material inside the slip ring and the design of the contact area. If the current is too large and the current - carrying capacity of the slip ring is insufficient, it will cause the slip ring to heat up. For high - power stretch wrapper machines, it may be necessary to choose a slip ring with a stronger current - carrying capacity, and its current parameter is generally above 10A.
• Rotational Speed: If the rotational speed of the slip ring is lower or much higher than the requirements of the equipment, it may affect the normal operation of the equipment. Generally, the rotational speed of the slip ring of the stretch wrapper machine is between 30 - 300r/min. The speed of ByTune's slip rings can reach 1000 rpm or even higher and can withstand the centrifugal force, friction, and heat generated by high - speed rotation.
• Installation Method: Common installation methods include through - hole type, flange type, and disc type. We should consider the outer diameter, inner diameter, height of the slip ring, and the installation position of the equipment.
• Protection Level: Since there is a lot of dust around the farmland, the slip ring you choose needs to have a relatively high protection level, such as IP54, IP65. ByTune's slip rings are sealed with silicone rings and insulating materials to reach the IP65 protection level. It is completely dust - proof and water - jet - proof.
• Brand and Quality: Choose well - known brands and reliable - quality slip ring suppliers. This can be evaluated by consulting the supplier's qualifications, customer reviews, product certifications, and other information. In addition, under the premise of meeting the equipment requirements, choose a reasonably - priced slip ring. Comprehensively consider the performance and service life of the slip ring and choose a product with high cost - performance.
