Description

Technical Field

[0001] The present invention relates to the technical field of dyeing machines, and particularly to a cloth lifting device. Background Art

[0002] A dyeing machine is used for dyeing cloth. Its structure includes a cylinder body, a cloth lifting device arranged in the cylinder body for driving the pushing of the cloth, a nozzle mechanism for spray-dyeing the cloth, and a filtering mechanism for recovering the dye liquor.

[0003] Among them, the cloth lifting device is an important component in the dyeing machine. Its function is to lift the cloth from a low place to a high place by relying on the nozzle at the same time. The cloth lifting device usually works in a dual-channel mode, that is, one motor drives two cloth lifting wheels to work. When cloth jams occur in one of the channels, the alarm device will cause the motor to stop working. However, the cloth on the cloth lifting wheel of the other channel will continue to be conveyed. Since the cloth lifting wheel does not rotate, there will be wear between the cloth and the cloth lifting wheel, and the cloth will be damaged, thereby increasing the manufacturing cost of the cloth.

[0004] Based on this, there is an urgent need for a cloth lifting device that can use the same motor to drive two independently controlled cloth lifting operations to solve the above problems. Summary of the Invention

[0005] In order to solve the above problems, the present invention provides a cloth lifting device. The cloth lifting device separately sets independent driving and stopping mechanisms for the two cloth lifting wheels of a dyeing machine with dual-channel operation on the basis of using the same set of transmission systems, so that the rotation and stopping of the cloth lifting wheels on both sides do not interfere with each other. The structure is simple and reliable, effectively ensuring the dyeing quality of the cloth.

[0006] The technical solution of the present invention is as follows:

[0007] A cloth lifting device includes a motor, a belt, a transmission shaft, and cloth lifting wheels. An intermediate support plate is fixedly arranged inside the head of the dyeing machine. The transmission shaft passes through the intermediate support plate and is rotatably installed on the head of the dyeing machine. The two cloth lifting wheels are rotatably installed on the transmission shaft inside the head of the dyeing machine. A motor connected to one end of the transmission shaft through a belt is fixedly arranged outside the head of the dyeing machine. A cloth lifting wheel driving mechanism and a cloth lifting wheel stopping mechanism are separately provided for each cloth lifting wheel inside the head of the dyeing machine; the cloth lifting wheel is combined with or disengaged from the transmission shaft under the action of the cloth lifting wheel driving mechanism, and the cloth lifting wheel is combined with or disengaged from the head of the dyeing machine under the action of the cloth lifting wheel stopping mechanism.

[0008] Further, the cloth lifting wheel driving and rotating mechanism includes a driving and rotating disc, a driving and rotating connecting rod, and a friction block A arranged on the transmission shaft. A plurality of disc driving and rotating air cavities are evenly distributed on the driving disc. The rod body of the driving and rotating connecting rod is hermetically and movably matched with the disc driving and rotating air cavities. A friction block A is fixedly arranged at one end of the driving and rotating connecting rod. A driving and rotating air path for connecting the disc driving and rotating air cavities with a compressed air source interface arranged outside the head of the dyeing machine is arranged on the driving disc. An elastic element, spring A, for applying a force to the driving and rotating connecting rod away from the cloth lifting wheel is arranged between the driving and rotating connecting rod and the driving disc.

[0009] Further, the driving and rotating air path includes a plate driving and rotating air passage, a shaft driving and rotating air ring cavity, a shaft driving and rotating air passage, and a disc internal driving and rotating air passage that sequentially lead from the compressed air source interface outside the head of the dyeing machine to the disc driving and rotating air cavities. The transmission shaft is hermetically and rotatably connected with the intermediate support plate.

[0010] Further, the cloth lifting wheel stopping and rotating mechanism includes a stopping cylinder, a stopping rod, and a friction block B arranged on the intermediate support plate. One end of the stopping rod is hermetically and movably matched with a stopping air cavity inside the stopping cylinder. A friction block B is fixedly arranged at the other end of the stopping rod. A stopping air path for connecting the stopping air cavity with a compressed air source interface arranged outside the head of the dyeing machine is arranged on the intermediate support plate. An elastic element, spring B, for applying a force to the stopping rod away from the cloth lifting wheel is arranged between the stopping rod and the intermediate support plate.

[0011] A cloth lifting method for a double-channel dyeing machine. The cloth lifting wheels on the left and right sides of the dyeing machine share a transmission system consisting of a motor, a belt, and a transmission shaft. Each cloth lifting wheel is provided with an independent cloth lifting wheel driving and rotating mechanism and a cloth lifting wheel stopping and rotating mechanism. The combination or disconnection of the cloth lifting wheel and the transmission shaft is realized through the cloth lifting wheel driving and rotating mechanism, and the combination or disconnection of the cloth lifting wheel and the head of the dyeing machine is realized through the cloth lifting wheel stopping and rotating mechanism.

[0012] Further, in the initial state: no compressed air is introduced into the disc driving and rotating air cavities. The driving and rotating connecting rod is away from the side of the cloth lifting wheel under the action of spring A. No compressed air is introduced into the stopping air cavity. The stopping rod is away from the side of the cloth lifting wheel under the action of spring B. The cloth lifting wheel is neither combined with the transmission shaft nor with the intermediate support plate. The cloth lifting wheel is rotatably matched with the transmission shaft in a free state.

[0013] When using the transmission system to drive the cloth lifting wheels on the left and right sides simultaneously: compressed air is introduced into the disc driving and rotating air cavities. The driving and rotating connecting rod overcomes the acting force of spring A under the action of the compressed air, causing the friction block A at one end of the driving and rotating connecting rod to closely adhere to the side of the cloth lifting wheel. No compressed air is introduced into the stopping air cavity. The stopping rod is away from the side of the cloth lifting wheel under the action of spring B. The cloth lifting wheel is combined with the transmission shaft and not combined with the intermediate support plate. The cloth lifting wheel rotates with the transmission shaft under the driving of the motor.

[0014] When it is necessary to remove the drive of the cloth lifting wheels on both the left and right sides simultaneously: exhaust the compressed air in the drive rotation air chamber on the disc to return to the initial state;

[0015] When it is necessary to stop the rotation of the cloth lifting wheels on both the left and right sides simultaneously: exhaust the compressed air in the drive rotation air chamber on the disc, introduce compressed air into the anti-rotation air chamber, and under the action of the compressed air, the anti-rotation rod overcomes the force of spring B so that the friction block at the end of the anti-rotation rod closely adheres to the side of the cloth lifting wheel;

[0016] When it is necessary to stop the rotation of only one of the cloth lifting wheels on the left or right side: exhaust the compressed air in the drive rotation air chamber on the disc of the side where the rotation is to be stopped. The drive connection rod moves away from the side of the cloth lifting wheel under the action of spring A. Introduce compressed air into the anti-rotation air chamber, and under the action of the compressed air, the anti-rotation rod overcomes the force of spring B so that the friction block at the end of the anti-rotation rod closely adheres to the side of the cloth lifting wheel; the cloth lifting wheel is not combined with the transmission shaft and is combined with the intermediate support plate at the same time, and the cloth lifting wheel and the intermediate support plate remain stationary; on the other side, keep the compressed air in the drive rotation air chamber on the disc and no compressed air in the anti-rotation air chamber;

[0017] When it is necessary to restart the rotation of the cloth lifting wheel on the side where the rotation has stopped, first exhaust the anti-rotation air chamber, and then introduce compressed air into the drive rotation air chamber on the disc.

[0018] Furthermore, the compressed air in the drive rotation air path and the anti-rotation air path of the drive and anti-rotation mechanisms for the cloth lifting wheels on both sides is provided by a compressed air source;

[0019] The compressed air source is divided into two paths and respectively supplies compressed air sources to the cloth lifting wheels on the left and right sides after passing through pressure reducing valves; after the pressure reducing valve, it is divided into two paths: the drive rotation air path and the anti-rotation air path; on the drive rotation air path or the anti-rotation air path, an electromagnetic on-off valve and an electromagnetic reversing valve are sequentially arranged to the drive rotation air path interface of the drive mechanism or the anti-rotation air path interface of the anti-rotation mechanism. A silencer is installed in the opposite direction of the electromagnetic reversing valve.

[0020] Furthermore, in the initial state: the electromagnetic on-off valves of the drive rotation air paths and the anti-rotation air paths on both sides are in the off state;

[0021] When using the transmission system to drive the cloth lifting wheels on both the left and right sides simultaneously: set the electromagnetic on-off valves on the drive rotation air paths on both sides to the ventilation state, set the electromagnetic reversing valve to the direction of the drive rotation air path interface, and the electromagnetic on-off valve of the anti-rotation air path is in the off state;

[0022] When it is necessary to remove the drive of the cloth lifting wheels on both the left and right sides simultaneously: set the electromagnetic on-off valves of the drive rotation air paths and the anti-rotation air paths on both sides to the off state, switch the electromagnetic reversing valves of the drive rotation air paths and the anti-rotation air paths to the silencers, and exhaust the air in the original air paths through the silencers;

[0023] When the cloth lifting wheels on both the left and right sides need to stop rotating simultaneously: set the electromagnetic on-off valves of the driving air paths on both sides to the off state, switch the electromagnetic reversing valve of the driving air path to the silencer, exhaust the original air path through the silencer, set the electromagnetic on-off valve of the stopping air path to the on state, and set the electromagnetic reversing valve to the direction of the stopping air path interface;

[0024] When only one of the cloth lifting wheels on the left or right side needs to stop rotating: set the electromagnetic on-off valve of the driving air path on the side to be stopped to the off state, switch the electromagnetic reversing valve of the driving air path to the silencer, exhaust the original air path through the silencer, set the electromagnetic on-off valve of the stopping air path to the on state, and set the electromagnetic reversing valve to the direction of the stopping air path interface;

[0025] When it is necessary to make the cloth lifting wheel on the stopped side rotate again, first set the electromagnetic on-off valve of the stopping air path on the stopped side to the off state, set the electromagnetic reversing valve to the direction that connects the stopping air path interface and the silencer, then set the electromagnetic on-off valve of the driving air path to the on state, and switch the electromagnetic reversing valve of the driving air path to the driving air path interface.

[0026] Furthermore, an one-way speed control valve is installed in front of the silencer, and an one-way speed control valve is installed in front of the driving air path interface or the stopping air path interface.

[0027] Furthermore, the sequential cooperation order of the driving combination rod and the stopping rod of the driving mechanism and the stopping mechanism to engage or disengage with the cloth lifting wheel is adjusted by the one-way speed control valve.

[0028] The beneficial effects of the present invention are as follows:

A cloth lifting device disclosed by the present invention, on the basis of using the same set of transmission system for the two cloth lifting wheels of a double-channel working dyeing machine, respectively sets independent driving mechanisms and stopping mechanisms, so that the rotation and stop of the cloth lifting wheels on both sides do not interfere with each other.

[0041] As Figure 1 shown, Figure 1 is a schematic structural diagram of a fabric lifting device of the present invention. The fabric lifting device of the double-channel dyeing machine includes a motor 1, a belt 2, a transmission shaft 3 and a fabric lifting wheel 5. An intermediate support plate 4a is fixedly arranged inside the dyeing machine head 4. The two fabric lifting wheels 5 are respectively arranged on both sides of the intermediate support plate 4a. The transmission shaft 3 penetrates through the outer shell of the dyeing machine head 4 and the intermediate support plate 4a and is rotatably installed on the dyeing machine head 4 through bearings. One end of the transmission shaft 3 outside the dyeing machine head 4 is connected to the motor 1 through a belt. The motor 1 provides rotational power to the transmission shaft 3. The fabric lifting wheel 5 is rotatably installed on the transmission shaft 3 through bearings. It should be noted specifically that rotatably installed in this article means that it can only rotate and cannot move horizontally. Since it is not a feature strongly related to the key point of the present invention, the structure for ensuring no left-right movement is not shown in the schematic diagram. The transmission shaft 3 can be prevented from moving in the dyeing machine head 4 by setting a bearing retaining ring at the bearings of the two. The fabric lifting wheel 5 can also be prevented from moving on the transmission shaft 3 by setting a bearing retaining ring at the bearings of the two.

[0042] The above is the prior art. The innovation of this patent lies in that each cloth lifting wheel 5 is separately provided with a cloth lifting wheel driving and rotating mechanism and a cloth lifting wheel stopping and rotating mechanism; the cloth lifting wheel 5 is combined with or disengaged from the transmission shaft 3 under the action of the cloth lifting wheel driving and rotating mechanism. When the cloth lifting wheel 5 is combined with the transmission shaft 3, the transmission shaft 3 can drive the cloth lifting wheel 5 to rotate. When the two are disengaged, the transmission shaft 3 will not provide rotational power to the cloth lifting wheel 5. The cloth lifting wheel 5 is combined with or disengaged from the dyeing machine head 4 under the action of the cloth lifting wheel stopping and rotating mechanism. When the cloth lifting wheel 5 is combined with the dyeing machine head 4, the cloth lifting wheel 5 remains relatively fixed with the dyeing machine head 4 and cannot rotate. When the cloth lifting wheel 5 is disengaged from the dyeing machine head 4, the dyeing machine head 4 cannot restrict the rotation of the cloth lifting wheel 5. The cloth lifting wheel driving and rotating mechanism and the cloth lifting wheel stopping and rotating mechanism should be used in coordination.

[0043] As Figure 2 shown, the cloth lifting wheel driving and rotating mechanism includes a driving disc 3a, a driving and combining rod 6, and a friction block A7. Two driving discs 3a are fixed or integrally formed on the transmission shaft 3. A number of on-disc driving air cavities 3a2 are evenly distributed on the driving disc 3a. The driving and combining rod 6 is a rod body that cooperates with the on-disc driving air cavities 3a2 on the side close to the cloth lifting wheel, and the side far from the cloth lifting wheel can be hermetically and movably penetrated out of the bottom of the on-disc driving air cavities 3a2 to the outside of the driving disc 3a and a spring A8 is installed between it and the driving disc 3a. The spring A8 applies a force to the driving and combining rod 6 away from the cloth lifting wheel 5. A friction block A7 is fixedly arranged at the end of the driving and combining rod 6 close to the cloth lifting wheel. An air driving path that connects the on-disc driving air cavities 3a2 with a compressed air source interface arranged outside the dyeing machine head 4 is arranged on the driving disc 3a; the hermeticity is achieved by installing a seal between the mating positions of the two components. In this article, the conventional method for hermetic mating is to install a seal.

[0044] Combined Figure 1 , Figure 2 and Figure 4 , the air driving path includes a plate driving air passage 4a3, a shaft driving air ring cavity 3c, a shaft driving air passage 3b, and a disc driving air passage 3a1 that sequentially lead from the compressed air source interface outside the dyeing machine head 4 to the on-disc driving air cavities 3a2. The transmission shaft 3 is hermetically and rotatably connected to the intermediate support plate 4a through a sealing ring 12; the plate driving air passage 4a3 first connects the compressed air from the outside of the dyeing machine head 4 to the shaft driving air ring cavity 3c at the joint of the transmission shaft 3 and the intermediate support plate 4a. Sealing rings 12 are arranged on both the left and right sides of the shaft driving air ring cavity 3c to ensure hermeticity with the intermediate support plate 4a. The shaft driving air passage 3b in the middle of the transmission shaft 3 connects the compressed air in the shaft driving air ring cavity 3c to the driving disc 3a. After the shaft driving air passage 3b reaches the driving disc 3a, it is divided into several paths according to the number of on-disc driving air cavities 3a2 provided.

[0045] As Figure 3As shown in the figure, the anti-rotation mechanism of the cloth lifting wheel includes an anti-rotation cylinder 4a1, an anti-rotation rod 9, and a friction block B10 provided on the intermediate support plate 4a. One end of the anti-rotation rod 9 is hermetically and movably engaged with the anti-rotation air chamber 4a11 inside the anti-rotation cylinder 4a1. A friction block B10 is fixedly provided at the other end of the anti-rotation rod 9. An anti-rotation air path is provided on the intermediate support plate 4a to connect the anti-rotation air chamber 4a11 with a compressed air source interface provided outside the dyeing machine head 4. An elastic element, spring B11, is provided between the anti-rotation rod 9 and the intermediate support plate 4a to apply a force to the anti-rotation rod 9 away from the cloth lifting wheel 5.

[0046] A cloth lifting method for a dual-channel dyeing machine, based on the above cloth lifting device, the cloth lifting wheels 5 on the left and right sides of the dyeing machine share a transmission system composed of a motor 1, a belt 2, and a transmission shaft 3. Each cloth lifting wheel 5 is provided with an independent cloth lifting wheel driving and rotating mechanism and an anti-rotation mechanism for the cloth lifting wheel. The combination or disengagement of the cloth lifting wheel 5 and the transmission shaft 3 is achieved through the cloth lifting wheel driving and rotating mechanism, and the combination or disengagement of the cloth lifting wheel 5 and the dyeing machine head 4 is achieved through the anti-rotation mechanism of the cloth lifting wheel.

[0047] In the initial state: There is no compressed air in the disk driving air chamber 3a2. The driving and combining rod 6 is far from the side of the cloth lifting wheel 5 under the action of spring A8. There is no compressed air in the anti-rotation air chamber 4a11. The anti-rotation rod 9 is far from the side of the cloth lifting wheel 5 under the action of spring B11. The cloth lifting wheel 5 is neither combined with the transmission shaft 3 nor with the intermediate support plate 4a. The cloth lifting wheel 5 is rotatably engaged with the transmission shaft 3 in a free state.

[0048] When using the transmission system to drive the cloth lifting wheels 5 on the left and right sides simultaneously: Compressed air is introduced into the disk driving air chamber 3a2. The driving and combining rod 6 overcomes the force of spring A8 under the action of the compressed air, causing the friction block A7 at one end of the driving and combining rod 6 to closely adhere to the side of the cloth lifting wheel 5. There is no compressed air in the anti-rotation air chamber 4a11. The anti-rotation rod 9 is far from the side of the cloth lifting wheel 5 under the action of spring B11. The cloth lifting wheel 5 is combined with the transmission shaft 3 and not combined with the intermediate support plate 4a. The cloth lifting wheel 5 rotates with the transmission shaft 3 under the drive of the motor 1.

[0049] When it is necessary to remove the drive of the cloth lifting wheels 5 on the left and right sides simultaneously: The compressed air in the disk driving air chamber 3a2 is exhausted, and it returns to the initial state.

[0050] When it is necessary to stop the rotation of the cloth lifting wheels 5 on the left and right sides simultaneously: The compressed air in the disk driving air chamber 3a2 is exhausted, and compressed air is introduced into the anti-rotation air chamber 4a11. The anti-rotation rod 9 overcomes the force of spring B11 under the action of the compressed air, causing the friction block 10 at the end of the anti-rotation rod 9 to closely adhere to the side of the cloth lifting wheel 5.

[0051] When only one of the cloth lifting wheels 5 on the left or right side stops rotating: exhaust the compressed air in the disk driving air chamber 3a2 on the side where the rotation is to be stopped. The driving engagement rod 6 moves away from the side of the cloth lifting wheel 5 under the action of the spring A8. Compressed air is introduced into the stopping air chamber 4a11. The stopping rod 9 overcomes the acting force of the spring B11 under the action of the compressed air, so that the friction block 10 at the end of the stopping rod 9 presses tightly against the side of the cloth lifting wheel 5. The cloth lifting wheel 5 is not combined with the transmission shaft 3 and is combined with the intermediate support plate 4a at the same time, and the cloth lifting wheel 5 and the intermediate support plate 4a remain stationary. On the other side, compressed air is maintained in the disk driving air chamber 3a2 and no compressed air is introduced into the stopping air chamber 4a11.

[0052] When it is necessary to make the cloth lifting wheel 5 on the side that has stopped rotating rotate again, first exhaust the stopping air chamber 4a11, and then introduce compressed air into the disk driving air chamber 3a2.

[0053] The compressed air in the driving air path and the stopping air path of the driving and stopping mechanisms of the cloth lifting wheels 5 on both sides is provided by a compressed air source.

[0054] As Figure 5 and Figure 6 shown, the compressed air source is divided into two paths and respectively supplies compressed air sources to the cloth lifting wheels 5 on the left and right sides after passing through pressure reducing valves. After the pressure reducing valves, it is divided into two paths: the driving air path and the stopping air path. An electromagnetic on-off valve and an electromagnetic reversing valve are sequentially arranged on the driving air path or the stopping air path to the driving air path interface of the driving mechanism or the stopping air path interface of the stopping mechanism. A silencer is installed in the opposite direction of the electromagnetic reversing valve.

[0055] In the initial state: the electromagnetic on-off valves of the driving air paths and the stopping air paths on both sides are in the off state.

[0056] When using the transmission system to drive the cloth lifting wheels 5 on the left and right sides at the same time: set the electromagnetic on-off valves on the driving air paths on both sides to the ventilation state, set the electromagnetic reversing valve to the direction of the driving air path interface, and the electromagnetic on-off valve of the stopping air path is in the off state.

[0057] When it is necessary to remove the drive of the cloth lifting wheels 5 on the left and right sides at the same time: set the electromagnetic on-off valves of the driving air paths and the stopping air paths on both sides to the off state, switch the electromagnetic reversing valves of the driving air paths and the stopping air paths to the silencers, and exhaust the air in the original air paths through the silencers.

[0058] When it is necessary to stop the rotation of the cloth lifting wheels 5 on the left and right sides at the same time: set the electromagnetic on-off valves of the driving air paths on both sides to the off state, switch the electromagnetic reversing valve of the driving air path to the silencer, exhaust the air in the original air path through the silencer, set the electromagnetic on-off valve of the stopping air path to the ventilation state, and set the electromagnetic reversing valve to the direction of the stopping air path interface.

[0059] When only one of the cloth lifting wheels 5 on the left or right side stops rotating: the electromagnetic on-off valve of the driving air path on the side to stop is in the off state, the electromagnetic reversing valve of the driving air path is switched to the muffler, and the air is exhausted from the original air path through the muffler. The electromagnetic on-off valve of the stopping air path is set to the air-permeable state, and the electromagnetic reversing valve is set to the direction of the stopping air path interface.

[0060] When it is necessary to make the cloth lifting wheel 5 on the stopped side rotate again, first set the electromagnetic on-off valve of the stopping air path on the stopped side to the off state, and the electromagnetic reversing valve is set to the direction of connecting the stopping air path interface with the muffler. Then set the electromagnetic on-off valve of the driving air path to the air-permeable state, and switch the electromagnetic reversing valve of the driving air path to the driving air path interface.

[0061] A one-way speed control valve is installed in front of the muffler, and a one-way speed control valve is installed in front of the driving air path interface or the stopping air path interface.

[0062] The sequential cooperation order of the engagement or disengagement of the driving combination rod 6 and the stopping rod 9 of the driving mechanism and the stopping mechanism with the cloth lifting wheel 5 is adjusted by the one-way speed control valve.

[0063] During the use process, it is necessary to ensure the coordination of the driving mechanism and the stopping mechanism. For example, when the stopping mechanism is enabled, it is necessary to ensure that the driving mechanism does not work. When the driving mechanism is enabled, the stopping mechanism does not work. How to determine the enabling and disabling timing of both during the switching gap between the driving mechanism and the stopping mechanism is provided by the present invention with a debugging method.

[0064] Switching and commissioning method for drive and anti-rotation mechanisms: Monitor the current value of motor 1; conduct commissioning in the state of idling the cloth lifting device, i.e., without feeding cloth. When compressed air is supplied to the drive air circuit from the initial state, the combination speed of the drive disc 3a and the cloth lifting wheel 5 can be adjusted by regulating the one-way commissioning valve on the drive air circuit; when it is necessary to switch from the drive state to the anti-rotation state, it is necessary to ensure that the drive mechanism is disengaged from the cloth lifting wheel 5 first and then the anti-rotation mechanism is combined with the cloth lifting wheel 5. There are two ways: 1. Do not install a one-way valve in the air circuit, and preset the time difference between the disconnection time of the electromagnetic on-off valve of the drive air circuit and the connection time of the electromagnetic on-off valve of the anti-rotation air circuit in the control system, so that the compressed air supplied to the drive mechanism in the drive air circuit is exhausted before supplying air to the anti-rotation mechanism. The time difference can be tested through the change of the current value of motor 1, that is, when the current value does not increase significantly until it suddenly increases during the switching between the two, the maximum time difference before the increase is the optimal time difference; 2. Adjust through the one-way valve. The one-way valve can adjust the combination or disengagement speed of the drive and anti-rotation mechanisms and the cloth lifting wheel 5. When switching from drive to anti-rotation, the electromagnetic reversing valve of the drive air circuit changes to the exhaust state, and the electromagnetic on-off valve of the anti-rotation air circuit is connected. The electromagnetic reversing valve is in the direction of the anti-rotation air circuit interface. By adjusting the one-way speed regulating valve of the muffler of the drive air circuit or the one-way commissioning valve before the anti-rotation air circuit interface, the disengagement time of the drive mechanism and the cloth lifting wheel 5 or the combination time of the anti-rotation mechanism and the cloth lifting wheel 5 can be adjusted. The optimal time difference is determined by detecting the current value of motor 1. When switching from anti-rotation to drive, the electromagnetic reversing valve of the anti-rotation air circuit changes to the volleyball state, and the electromagnetic reversing valve of the drive air circuit changes to the direction of the drive air circuit interface. By adjusting the one-way speed regulating valve of the muffler of the anti-rotation air circuit or the one-way commissioning valve before the drive air circuit interface, the disengagement time of the anti-rotation mechanism and the cloth lifting wheel 5 or the combination time of the drive mechanism and the cloth lifting wheel 5 can be adjusted. The optimal time difference is determined by detecting the current value of motor 1.
