Description

Technical Field

[0001] This application relates to the technical field of film peeling, and in particular to an efficient film peeling device and method thereof. Background Art

[0002] In industrial activities, it is sometimes necessary to peel a film. For example, in the processing of plastic films, it is necessary to blow-mold the film. However, due to the limitations of the blow-molding process, if only a single-layer film is blow-molded, there will be a problem that the film cannot be blow-molded into shape. Based on this, for the processing of plastic films, usually a double-layer film is first blow-molded, and then the double-layer film is wound separately. For example, when producing a TPU film, during the production process of TPU, because it is too thin, it must adhere to a pe film and be peeled off after cooling for separate winding.

[0003] In the related art, there is a common film peeling device, which includes a winding-off roller, a first winding roller, and a second winding roller, and each of the winding-off roller, the first winding roller, and the second winding roller is driven by a motor. When in use, the double-layer film coil to be wound off is placed on the winding-off roller, one layer of the double-layer film is connected to the first winding roller, and the other layer of the double-layer film is connected to the second winding roller. During winding-off, the winding-off roller releases the double-layer film, the first winding roller winds one single-layer film, and the second winding roller winds the other single-layer film, so as to separate the two layers of film.

[0004] However, as the winding-off work progresses, the double-layer film on the winding-off roller becomes thinner and thinner, and the length of the double-layer film released by the winding-off roller in one rotation becomes shorter and shorter; while the single-layer films wound on the first winding roller and the second winding roller become thicker and thicker, and the length of the single-layer film wound by the first winding roller and the second winding roller in one rotation becomes longer and longer. Therefore, it is difficult to ensure the stability of the tension degree of the film during the separation process. Excessive changes in the tension degree will affect the quality of the film, causing the film to wrinkle, stretch thinly or even tear. And there may also be differences in the thickness of the two single-layer films, resulting in inconsistent tension degrees of the two single-layer films, and the imbalance of the interaction force when the two single-layer films are separated. Summary of the Invention

[0005] In order to improve the stability of the tension degree of the film during the separation process, this application provides an efficient film peeling device and method thereof.

[0006] In the first aspect, an efficient film peeling device provided by this application adopts the following technical solution: An efficient film stripping device, comprising a frame, on which there are provided a winding roller for releasing a double-layer film, a first winding roller for winding one single-layer film, a second winding roller for winding the other single-layer film, a first motor for driving the first winding roller to rotate, a driving mechanism for driving the second winding roller to rotate, and further comprising a control module, a first detection module, and a second detection module. The first motor, the driving mechanism, the first detection module, and the second detection module are all communicatively connected to the control module. There are also provided a first tensioning roller and a second tensioning roller on the frame. The first tensioning roller is used to abut against one single-layer film, and the first detection module is used to detect the pressure borne by the first tensioning roller and send the detected pressure as first pressure information to the control module. The second tensioning roller is used to abut against the other single-layer film, and the second detection module is used to detect the pressure borne by the second tensioning roller and send the detected pressure as second pressure information to the control module. A first pressure threshold and a second pressure threshold are preset in the control module. Among them, the first pressure threshold is the standard range value of the pressure borne by the first tensioning roller, and the second pressure threshold is the standard range value of the pressure borne by the second tensioning roller. The control module is used to receive the first pressure information and compare the first pressure information with the first pressure threshold. If the pressure value in the first pressure information is higher than or lower than the first pressure threshold, a deceleration or acceleration information is sent to the first motor. The first motor is used to reduce or increase the output rotation speed when receiving the deceleration or acceleration information. The control module is used to receive the second pressure information and compare the second pressure information with the second pressure threshold. If the pressure value in the second pressure information is higher than or lower than the second pressure threshold, a deceleration or acceleration information is sent to the driving mechanism. The driving mechanism is used to reduce or increase the output rotation speed when receiving the deceleration or acceleration information.

[0007] By adopting the above technical solution, the first detection module detects the pressure on the first tension roller in real time, converts it into first pressure information and sends it to the control module. The control module receives and judges whether the pressure value in the first pressure information is within the preset first standard threshold. If it is higher than the maximum value of the first standard threshold, a deceleration signal is sent to the first motor. If it is lower than the minimum value of the first standard threshold, an acceleration signal is sent to the first motor. When the first motor receives the deceleration signal, its speed is reduced and one single-layer film is relaxed. When the first motor receives the acceleration signal, its speed is increased and one single-layer film is tensioned. Similarly, the second detection module detects the pressure on the second tension roller in real time, converts it into second pressure information and sends it to the control module. The control module receives and judges whether the pressure value in the second pressure information is within the preset second standard threshold. If it is higher than the maximum value of the second standard threshold, a deceleration signal is sent to the driving mechanism. If it is lower than the minimum value of the second standard threshold, an acceleration signal is sent to the driving mechanism. When the driving mechanism receives the deceleration signal, its speed is reduced and the other single-layer film is relaxed. When the driving mechanism receives the acceleration signal, its speed is increased and the other single-layer film is tensioned. In this way, during the film peeling process, the tension degree of the film will not exceed the given range for a long time, and large fluctuations in the tension degrees of the two single-layer films are avoided as much as possible, improving the stability of the tension degree of the film during the separation process, thereby preventing the film from wrinkling, thinning or tearing and improving the product quality.

[0008] Optionally, both the first detection module and the second detection module are pressure sensors.

[0009] By adopting the above technical solution, using pressure sensors as the first detection module and the second detection module can directly and accurately convert the tension degree of the film borne by the tension roller into an electrical signal and send it to the control module.

[0010] Optionally, two slide rails are fixedly arranged on the frame. A mounting seat is slidably arranged on the slide rails. The first tension roller is rotatably connected to the mounting seat on one of the slide rails. The second tension roller is rotatably connected to the mounting seat on the other slide rail. The first detection module is fixed at the end of one of the slide rails. The second detection module is fixed at the end of the other slide rail. A thrust spring is arranged in the slide rail. One end of the thrust spring abuts against the mounting seat, and the other end of the thrust spring abuts against the first detection module or the second detection module. The thrust spring is in a compressed state.

[0011] By adopting the above technical solution, the guide rails provide guidance for the force transmission directions of the first tension roller and the second tension roller. When the tension degree of the single-layer film changes, the pressure on the corresponding first tension roller or second tension roller changes. The spring generates a slight deformation in response to the pressure change and transmits the pressure to the corresponding first detection module or second detection module, thereby detecting the pressure of the first tension roller and the second tension roller.

[0012] Optionally, the driving mechanism includes a driving wheel, a transmission belt, an adjusting disc, a movable block, and a movable assembly. The driving wheel is coaxially fixed to the first winding roller, the adjusting disc is coaxially fixed to the second winding roller, and the adjusting disc is evenly and spaced with a plurality of movable grooves in the circumferential direction. The movable grooves are opened along the radial direction of the adjusting disc. A plurality of movable blocks are provided, and the movable blocks correspond to the movable grooves one by one. The movable blocks are slidably matched with the movable grooves along the opening direction of the movable grooves. All the movable blocks together form a driven wheel. The movable assembly is used to drive all the movable blocks to approach or move away from the axis of the adjusting disc at the same time. The transmission belt is arranged to transmit power between the driving wheel and the driven wheel. One end of the transmission belt is sleeved on the driving wheel, and the other end of the transmission belt is sleeved on the driven wheel.

[0013] By adopting the above technical solution, when the first winding roller rotates, it can drive the driving wheel to rotate synchronously at the same time. The first motor provides a power source for the first winding roller and the second winding roller at the same time, ensuring that the first winding roller and the second winding roller start and stop at the same time, and there will be no situation of sequential movement, preventing the huge difference in the tension received by the two single-layer films during the starting stage and causing damage to the films. During the rewinding process, when the tension of the film wound by the second winding roller exceeds the rated value, the control module will instruct the movable assembly to act according to the pressure information fed back by the second detection module. The movable assembly drives the movable blocks to move in the movable grooves of the adjusting disc, thereby changing the outer diameter of the driven wheel composed of the movable blocks. When the outer diameter of the driven wheel changes, the transmission ratio between the driving wheel and the driven wheel of the transmission belt changes accordingly, and the rotation speed of the adjusting disc and the second winding roller coaxially therewith is adjusted, which can respond in time to the difference in the tension of the two single-layer films and further ensure the coordination of the two single-layer films during the separation process.

[0014] Optionally, the movable assembly includes an electric push rod, a sliding sleeve, and a connecting rod. The sliding sleeve is slidably arranged along the axis direction of the adjusting disc. A plurality of connecting rods are provided and correspond to the movable blocks one by one. One end of the connecting rod is hinged to the corresponding movable block, and the other ends of all the connecting rods are hinged to the sliding sleeve. A bracket is fixedly arranged on the frame, the electric push rod is fixedly arranged on the bracket, the moving direction of the output end of the electric push rod is parallel to the axis direction of the adjusting disc, and the output end of the electric push rod is rotatably connected to the sliding sleeve.

[0015] By adopting the above technical solution, the push rod is installed on the bracket as the power core of the active component to ensure stability. When the control module issues an instruction, the output end of the electric push rod expands and contracts along the axis direction of the adjustment disk, driving the sliding sleeve to slide synchronously. Since the sliding sleeve is hinged with multiple connecting rods, and the connecting rods are respectively hinged with the corresponding movable blocks, the linear motion of the sliding sleeve is converted into the radial movement of each movable block along the movable groove of the adjustment disk through the connecting rod, and the sliding motion of all movable blocks is carried out simultaneously and synchronously. In addition, the rotational connection between the sliding sleeve and the output end of the electric push rod allows the sliding sleeve to generate torsional motion with the electric push rod when rotating with the adjustment disk, eliminating the torsional difference.

[0016] Optionally, the electric push rod is communicatively connected to a control module, and the driving mechanism is used to drive the sliding sleeve to move closer to or away from the adjusting disk when receiving deceleration or acceleration information sent by the control module.

[0017] By adopting the above technical solution, when the control module determines that the film tension exceeds the second standard threshold according to the pressure information fed back by the second detection module, a deceleration or acceleration instruction is sent to the electric push rod. The electric push rod responds to the instruction, drives the sliding sleeve to approach or move away from the adjustment disk, drives the connecting rod to change the position of the movable block in the movable groove of the adjustment disk, and then adjusts the outer diameter of the driven wheel to achieve the adjustment of the speed of the second winding roller.

[0018] Optionally, a guide rod is fixedly provided on the end surface of the adjusting disk, and the sliding sleeve is slidably matched with the guide rod.

[0019] By adopting the above technical solution, the guide rod provides a guide for the sliding of the sleeve. When the electric push rod drives the sleeve to approach or move away from the adjusting disk, the guide rod ensures that the sleeve moves smoothly along the axial direction of the adjusting disk, thereby minimizing the displacement or shaking of the sleeve during movement.

[0020] Optionally, a thrust ball bearing is provided between the sliding sleeve and the output end of the electric push rod, one side of the thrust ball bearing is fixedly connected to the output end of the electric push rod, and the other side of the thrust ball bearing is fixedly connected to the sliding sleeve.

[0021] By adopting the above technical solution, when the electric push rod pushes the sleeve to move, the thrust ball bearing can reduce the friction resistance between the electric push rod and the sleeve. Since the sleeve needs to change its position frequently to adjust the outer diameter of the driven wheel during the rotation of the driven wheel, the thrust ball bearing can also withstand a certain axial load, ensuring the stability of the connection between the output end of the electric push rod and the sleeve, and ensuring the reliability of power transmission even under high-frequency adjustment actions.

[0022] Optionally, a guide rail is fixedly arranged on the frame, a pressing block is slidably arranged on the guide rail, a tensioning roller is rotatably arranged on the pressing block, the pressing wheel abuts against the outer side of the transmission belt, a pressing spring is further arranged in the guide rail, and the pressing spring drives the pressing block to approach the transmission belt.

[0023] By adopting the above technical solution, as the outer diameter of the driven wheel changes, the length requirement of the transmission belt will also change accordingly. The pressing spring continuously applies a force to drive the pressing block to slide on the guide rail, so that the pressing wheel always abuts against the outer side of the transmission belt. Automatically compensate for the length difference caused by the change of the outer diameter of the driven wheel, and prevent the transmission belt from loosening or slipping.

[0024] In a second aspect, a method for using an efficient film peeling device provided by the present application adopts the following technical solution, including the following steps: S1. Install the double-layer film coil to be unrolled on the unrolling roller, connect and wind the end of one single-layer film of the double-layer film on the first winding roller, and connect and wind the end of the other single-layer film of the double-layer film on the second winding roller; S2. Set a first standard threshold and a second standard threshold in the control module; S3. Start the first motor, the first winding roller rotates and winds one single-layer film, and at the same time, the driving wheel rotates with the first winding roller and drives the driven wheel to rotate through the transmission belt, the driven wheel drives the adjusting disc to rotate, and the second winding roller rotates with the adjusting disc and winds the other single-layer film; S4. The first tensioning roller transmits the pressure to the first detection module through one of the thrust springs, the first detection module converts the received pressure into first pressure information and sends it to the control module; the control module receives and judges whether the pressure value in the first pressure information is within the first standard threshold preset in S2. If it is higher than the maximum value of the first standard threshold, a deceleration signal is sent to the first motor. If it is lower than the minimum value of the first standard threshold, an acceleration signal is sent to the first motor; the first motor reduces the speed when receiving the deceleration signal, and one single-layer film is relaxed; the first motor increases the speed when receiving the acceleration signal, and one single-layer film is tensioned; The second tensioning roller conducts pressure to the second detection module through another thrust spring. The second detection module converts the received pressure into second pressure information and sends it to the control module. The control module receives and determines whether the pressure value in the second pressure information is within the second standard threshold preset in S2. If it is higher than the maximum value of the second standard threshold, it sends a deceleration signal to the electric push rod. If it is lower than the minimum value of the second standard threshold, it sends an acceleration signal to the electric push rod. When the electric push rod receives the deceleration signal, it drives the sliding sleeve to approach the adjusting disc. The sliding sleeve drives all the movable blocks to move away from each other through the connecting rod, the outer diameter of the driven wheel increases, the rotation speed of the adjusting disc decreases, and the other single-layer film is relaxed. When the electric push rod receives the acceleration signal, it drives the sliding sleeve away from the adjusting disc. The sliding sleeve drives all the movable blocks to approach each other through the connecting rod, the outer diameter of the driven wheel decreases, the rotation speed of the adjusting disc increases, and the other single-layer film is tensioned.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. By setting the first motor, the driving mechanism, the control module, the first detection module, and the second detection module, the first detection module and the second detection module feedback the pressure information to the control module. The control module sends deceleration or acceleration information to the first motor and the driving mechanism according to the preset pressure threshold, so that during the film peeling process, the tension degree of the film can always be maintained within a relatively stable range, improving the quality and efficiency of film separation. 2. By setting the driving wheel, the transmission belt, the adjusting disc, the movable blocks, the movable components, and the movable grooves, the first winding roller and the second winding roller can be driven by the same power source (i.e., the first motor), ensuring the synchronous start and stop of the two winding rollers, and minimizing the film damage caused by the excessive difference in the instantaneous tension received by the two single-layer films during the start-up stage. 3. By setting the electric push rod, the sliding sleeve, the connecting rod, the bracket, the guide rod, and the thrust ball bearing, the sliding sleeve converts the linear motion into the radial movement of the movable blocks through the connecting rod, realizing the synchronous adjustment of the outer diameter of the driven wheel, enabling the rotation speed of the second winding roller to be adjusted in a timely manner according to the film tension degree, and ensuring the smooth progress of the film peeling process.

[0027] The following will further describe the present application in detail Figure 1 - appendix Figure 3 and make a further detailed description of the present application.

When replacing the film, the locking pin is pulled out of the pin hole, and the rod body is moved out of the rotating end plate along the rod groove so as to replace the film on the rod body.

[0030] Referring to Figure 2 and Figure 4, the film splitting roller 11 is used to release the double-layer film, the first winding roller 12 is used to wind one single-layer film, and the second winding roller 13 is used to wind the other single-layer film.

The movable slots 231 are opened along the radial direction of the adjusting disc 23. A plurality of movable blocks 232 are provided. The movable blocks 232 correspond to the movable slots 231 one by one. The movable blocks 232 are slidably matched with the movable slots 231 along the opening direction of the movable slots 231. All the movable blocks 232 together form a driven wheel with a variable outer diameter.

[0032] Referring to Figure 2 and Figure 3 , the movable assembly 24 is used to drive all the movable blocks 232 to approach or move away from the axis of the adjusting disc 23 simultaneously. Specifically, the movable assembly 24 includes an electric push rod 241, a sliding sleeve 243, and a connecting rod 244. A guide rod 245 is vertically and fixedly arranged on the end face of the adjusting disc 23 on the side away from the frame 1. The sliding sleeve 243 is slidably matched with the guide rod 245. The sliding direction of the sliding sleeve 243 is parallel to the axis direction of the adjusting disc 23. The cross section of the guide rod 245 in the length direction is polygonal, which is used to reduce the torsion between the sliding sleeve 243 and the guide rod 245. A plurality of connecting rods 244 are provided and correspond to the movable blocks 232 one by one. One end of the connecting rod 244 is hinged to the corresponding movable block 232. The hinge axis of the connecting rod 244 and the movable block 232 is perpendicular to the radial line of the adjusting disc 23. The other ends of all the connecting rods 244 are hinged to the sliding sleeve 243.

[0033] Referring to Figure 2 and Figure 3 , a bracket 15 is fixedly arranged on the frame 1. The electric push rod 241 is fixedly arranged on the bracket 15. The moving direction of the output end of the electric push rod 241 is parallel to the axis direction of the adjusting disc 23. The output end of the electric push rod 241 is rotatably connected to the sliding sleeve 243 through a thrust ball bearing 242. One side of the thrust ball bearing 242 is fixedly connected to the output end of the electric push rod 241, and the other side of the thrust ball bearing 242 is fixedly connected to the sliding sleeve 243.

[0034] Reference Figure 2 and Figure 5 The transmission belt 22 is arranged between the driving wheel 21 and the driven wheel for transmission, one end of the transmission belt 22 is sleeved on the driving wheel 21, and the other end of the transmission belt 22 is sleeved on the driven wheel. Rope grooves for the transmission belt 22 to be inserted are provided on the peripheral walls of the driving wheel 21 and the driven wheel. A guide rail 16 is fixedly arranged on the frame 1, a pressing block 161 is slidably arranged on the guide rail 16, a pressing wheel 162 is rotatably arranged on the pressing block 161, the pressing wheel 162 abuts against the outer side of the transmission belt 22, and a pressing spring 163 is also arranged in the guide rail 16, the pressing spring 163 drives the pressing block 161 to approach the transmission belt 22 to ensure that the transmission belt 22 is always in a tensioned state.

[0035] Reference Figures 2 to 5 After the first motor 14 is started, the driving shaft of the first motor 14 drives the first winding roller 12 to rotate and start to wind up one of the single-layer films. At the same time, the driving wheel 21 also rotates synchronously, and the driven wheel composed of the movable block 232 is pulled to rotate by the transmission belt 22, so that the adjustment disk 23 connected to the driven wheel drives the second winding roller 13 to rotate together and start to wind up another single-layer film. And in this process, the split winding roller 11 releases the double-layer film under the drive of the second motor. If the rotation speed of the first winding roller 12 and the second winding roller 13 is not coordinated, that is, the tension degree of the two single-layer films is too different. Drive the cylinder to extend or retract the output end, and the movable blocks 232 move away from or close to each other, so that the outer diameter of the driven wheel increases or decreases accordingly, and the rotation speed of the second winding roller 13 decreases or increases accordingly, thereby adjusting the rotation speed of the second winding roller 13. In this way, the first winding roller 12 and the second winding roller 13 are started and stopped at the same time. On the one hand, the acceleration difference during the rotation start phase is eliminated as much as possible; on the other hand, it helps to prevent a state in which one roller rotates and the other roller stops.

[0036] Reference Figure 4 , the first detection module 4 and the second detection module 5 are both pressure sensors. Two slide rails 6 are fixedly arranged on the frame 1, and a mounting seat 61 is slidably arranged on the slide rails 6. The first tensioning roller 63 is rotatably connected to the mounting seat 61 on one of the slide rails 6, and the second tensioning roller 64 is rotatably connected to the mounting seat 61 on the other slide rail 6. The first detection module 4 is fixed at the end of one of the slide rails 6, and the second detection module 5 is fixed at the end of the other slide rail 6. A thrust spring 62 is arranged in the slide rail 6, one end of the thrust spring 62 is against the mounting seat 61, and the other end of the thrust spring 62 is against the first detection module 4 or the second detection module 5, and the thrust spring 62 is in a compressed state.

[0037] Reference Figure 1 and Figure 4, the first motor 14, the electric push rod 241 in the driving mechanism 2, the first detection module 4, and the second detection module 5 are all communicatively connected to the control module 3, and the control module 3 is a PLC controller. The first tensioning roller 63 is used to abut against one of the single-layer films, and the first detection module 4 is used to detect the pressure borne by the first tensioning roller 63 and send the detected pressure as the first pressure information to the control module 3.

[0038] Refer to Figure 1 With Figure 4 , the second tensioning roller 64 is used to abut against the other single-layer film, and the second detection module 5 is used to detect the pressure borne by the second tensioning roller 64 and send the detected pressure as the second pressure information to the control module 3.

[0039] Refer to Figure 1 With Figure 4 , the control module 3 is preset with a first pressure threshold and a second pressure threshold. Among them, the first pressure threshold is the standard range value of the pressure borne by the first tensioning roller 63, and the second pressure threshold is the standard range value of the pressure borne by the second tensioning roller 64.

[0040] Refer to Figure 1 With Figure 2 , the control module 3 is used to receive the first pressure information and compare it with the first pressure threshold based on the first pressure information. If the pressure value in the first pressure information is higher than or lower than the first pressure threshold, a deceleration or acceleration information is sent to the first motor 14. The first motor 14 is used to reduce or increase the output speed when receiving the deceleration or acceleration information.

[0041] Refer to Figures 1 to 3 , the control module 3 is used to receive the second pressure information and compare it with the second pressure threshold based on the second pressure information. If the pressure value in the second pressure information is higher than or lower than the second pressure threshold, a deceleration or acceleration information is sent to the electric push rod 241 in the driving mechanism 2. The electric push rod 241 in the driving mechanism 2 is used to extend the output end when receiving the deceleration information, that is, to drive the sliding sleeve 243 to approach the adjusting disc 23, drive all the movable blocks 232 to move away from each other, increase the outer diameter of the driven wheel, thereby reducing the rotation speed of the adjusting disc 23; or used to retract the output end when receiving the acceleration information, that is, to drive the sliding sleeve 243 to move away from the adjusting disc 23, drive all the movable blocks 232 to approach each other, reduce the outer diameter of the driven wheel, thereby increasing the rotation speed of the adjusting disc 23.

[0042] The implementation principle of an efficient film peeling device according to an embodiment of the present application is as follows: When performing film peeling work, the first motor 14 drives the first winding roller 12 to rotate, and starts to wind one single-layer film. At the same time, the driving wheel 21 fixedly connected to the first winding roller 12 coaxially also rotates. The driving wheel 21 drives the driven wheel composed of the movable blocks 232 to rotate through the transmission belt 22, and then drives the adjusting disk 23 connected to the driven wheel to drive the second winding roller 13 to rotate, and starts to wind the other single-layer film. At the same time, the second motor drives the splitting roller 11 to rotate, and continuously releases the double-layer film.

[0043] During the film peeling process, the first detection module 4 detects the pressure borne by the first tension roller 63 and sends the first pressure information to the control module 3. The second detection module 5 detects the pressure borne by the second tension roller 64 and sends the second pressure information to the control module 3. After receiving the first pressure information, the control module 3 compares the pressure value therein with a preset first pressure threshold. If the pressure value is higher than the first pressure threshold, it means that the tension degree of this single-layer film is too large. The control module 3 sends a deceleration message to the first motor 14. After receiving the message, the first motor 14 reduces the output speed, so that this single-layer film is relaxed. If the pressure value is lower than the first pressure threshold, the control module 3 sends an acceleration message to the first motor 14, and the first motor 14 increases the output speed to tension this single-layer film.

[0044] For the second pressure information, the control module 3 also compares the pressure value in the second pressure information with the second pressure threshold. If the pressure value is higher than the second pressure threshold, the control module 3 sends a deceleration message to the electric push rod 241 in the driving mechanism 2. The outer extension output end of the electric push rod 241 drives the sliding sleeve 243 to approach the adjusting disk 23, and through the connecting rod 244, all the movable blocks 232 move away from each other, increasing the outer diameter of the driven wheel. Since the rotational speed of the driving wheel 21 remains unchanged, after the outer diameter of the driven wheel increases, the transmission ratio changes, and the rotational speeds of the adjusting disk 23 and the second winding roller 13 coaxially connected thereto decrease, so that the other single-layer film is relaxed. If the pressure value is lower than the second pressure threshold, the control module 3 sends an acceleration message to the electric push rod 241, and the inner contraction output end of the electric push rod 241 drives the sliding sleeve 243 to move away from the adjusting disk 23, and through the connecting rod 244, all the movable blocks 232 move closer to each other, reducing the outer diameter of the driven wheel, increasing the rotational speeds of the adjusting disk 23 and the second winding roller 13, and tensioning the other single-layer film.

[0045] An embodiment of the present application also discloses a usage method of an efficient film peeling device, including the following steps: S1. Install the double-layer film coil to be split on the splitting roller 11, connect and wind the end of one single-layer film of the double-layer film on the first winding roller 12, and connect and wind the end of the other single-layer film of the double-layer film on the second winding roller 13; S2. Set a first standard threshold and a second standard threshold in the control module 3; S3. Start the first motor 14. The first winding roller 12 rotates to wind one single-layer film. Meanwhile, the driving wheel 21 rotates with the first winding roller 12 and drives the driven wheel to rotate through the transmission belt 22. The driven wheel drives the adjusting disk 23 to rotate, and the second winding roller 13 rotates with the adjusting disk 23 to wind the other single-layer film; S4. The first tension roller 63 transmits the pressure to the first detection module 4 through one of the thrust springs 62. The first detection module 4 converts the received pressure into first pressure information and sends it to the control module 3. The control module 3 receives and determines whether the pressure value in the first pressure information is within the first standard threshold preset in S2. If it is higher than the maximum value of the first standard threshold, a deceleration signal is sent to the first motor 14. If it is lower than the minimum value of the first standard threshold, an acceleration signal is sent to the first motor 14. When the first motor 14 receives the deceleration signal, its speed is reduced and one single-layer film is relaxed. When the first motor 14 receives the acceleration signal, its speed is increased and one single-layer film is tensioned; The second tension roller 64 transmits the pressure to the second detection module 5 through the other thrust spring 62. The second detection module 5 converts the received pressure into second pressure information and sends it to the control module 3. The control module 3 receives and determines whether the pressure value in the second pressure information is within the second standard threshold preset in S2. If it is higher than the maximum value of the second standard threshold, a deceleration signal is sent to the electric push rod 241. If it is lower than the minimum value of the second standard threshold, an acceleration signal is sent to the electric push rod 241. When the electric push rod 241 receives the deceleration signal, it drives the sliding sleeve 243 to approach the adjusting disk 23. The sliding sleeve 243 drives all the movable blocks 232 to move away from each other through the connecting rod 244, the outer diameter of the driven wheel increases, the rotation speed of the adjusting disk 23 decreases, and the other single-layer film is relaxed. When the electric push rod 241 receives the acceleration signal, it drives the sliding sleeve 243 to move away from the adjusting disk 23. The sliding sleeve 243 drives all the movable blocks 232 to approach each other through the connecting rod 244, the outer diameter of the driven wheel decreases, the rotation speed of the adjusting disk 23 increases, and the other single-layer film is tensioned.
