Description

Technical Field

[0001] The utility model relates to the technical field of film material processing equipment, in particular to an automatic winding device for finished film materials. Background Art

[0002] Die-cutting products are widely used in the automotive manufacturing and electronics industries, especially in the flat panel display industry, where layered film materials are often used, including insulating materials, shockproof materials, heat-resistant insulation materials, adhesive products, dust-proof materials, and shielding materials, all of which are manufactured using die-cutting technology.

[0003] After the film material is die-cut, the finished film material needs to be rolled into a coil for storage. In the prior art, a plurality of winding shafts rotating in the same direction are usually provided. The finished film material is first pulled onto one of the winding shafts for winding. When the finished film material on the winding shaft is wound to a specific diameter, the finished film material is cut and then pulled onto other winding shafts for winding, thereby realizing the automatic winding operation of the finished film material with high operating efficiency. However, in actual processing, the front side of the film material after the die-cutting operation is sometimes on the upper side and sometimes on the lower side. In order to avoid damage to the front side of the finished film material when winding, when the front side of the finished film material is on the upper side, the finished film material needs to be wound in a clockwise manner, and when the front side of the finished film material is on the lower side, the finished film material needs to be wound in a counterclockwise manner. However, in the existing automatic winding devices, due to the need to consider the coordination relationship between the winding shaft and other structural components, a single winding method is usually adopted, and only clockwise automatic winding or counterclockwise automatic winding can be performed. It is impossible to automatically switch between clockwise automatic winding and counterclockwise automatic winding, and cannot meet the above-mentioned processing and use requirements. Utility Model Content

[0004] In order to solve the problems existing in the above-mentioned background technology, the utility model provides an automatic winding device for finished film materials, which can automatically switch between two working states of automatic clockwise winding and automatic counterclockwise winding, without manual intervention, and the equipment is more applicable.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The utility model provides an automatic winding device for finished film materials, comprising a mounting panel, a turntable, a winding shaft, a cutting component, and two adhesive tape positioning devices;

[0007] The front of the installation panel is provided with a turntable, a cutting assembly, and two tape positioning devices, at least one winding shaft is installed on the front of the turntable, and a first driving assembly for driving the winding shaft to freely switch between clockwise rotation and counterclockwise rotation is installed on the back of the turntable, and a second driving assembly connected to the turntable is provided on the back of the installation panel, and the second driving assembly drives the turntable to rotate clockwise or counterclockwise, and the cutting assembly can cut the finished film material transported inside, and the two tape positioning devices are located close to the edge of the turntable, and are used to stick tape on the end of the finished film material and stick the tape to the outside of the winding shaft, one of the tape positioning devices cooperates with the winding shaft to wind the finished film material counterclockwise, and the other tape positioning device cooperates with the winding shaft to wind the finished film material clockwise.

[0008] Furthermore, the tape positioning device includes a mounting frame, a tape assembly and a pressure wheel assembly, the mounting frame is arranged on the front side of the mounting panel, and a height adjustment assembly is provided on the mounting frame, the adjustment end of the height adjustment assembly is connected to the tape assembly used to stick the tape to the end of the finished film material and the pressure wheel assembly used to press the pasted tape toward and stick it to the outside of the winding shaft, and the pressure wheel assembly is located close to the side of the turntable.

[0009] In the prior art, the glue is applied to the end of the finished film material by a glue roller, and the glue roller is pressed down to position the end of the finished film material to the outside of the winding shaft through the glue. This method has the problem that the end of the finished film material is not firmly connected to the outside of the winding shaft. Under the action of the winding traction force, the end of the finished film material is easily separated from the outside of the winding shaft, and it is easy to cause pollution to the outside of the winding shaft. In this application, by designing the specific structure of the tape positioning device, the height adjustment component drives the tape assembly and the pressure wheel assembly to extend, and when the end of the finished film material passes through the tape assembly, the tape assembly sticks the tape to the end of the finished film material, and the finished film material is transported backward to the pressure wheel assembly. The wheel body in the pressure wheel assembly contacts the back of the tape, and presses and sticks the adhesive layer of the tape to the corresponding outside of the winding shaft, and then the height adjustment component drives the tape assembly and the pressure wheel assembly to retract, so that the finished film material can be wound normally.

[0010] Furthermore, the pressing wheel assembly includes a guide wheel unit and a pressing wheel unit, both of which are connected to the adjustment end of the height adjustment assembly, the guide wheel unit is located between the adhesive tape assembly and the pressing wheel unit, and the height adjustment assembly controls the pressing wheel in the pressing wheel unit to extend out of the mounting frame until the outer side of the pressing wheel contacts the outer side of the winding shaft.

[0011] Whether to set up a guide wheel unit can be determined based on specific usage needs. When the conveying direction of the finished film material is not suitable for being directly introduced into the position where the outer side of the pressing wheel contacts the outer side of the winding shaft, it is necessary to use the guide wheel and the pressing wheel to cooperate to form a directional guidance for the conveying direction of the finished film material. The end of the finished film material can be smoothly introduced into the position where the outer side of the pressing wheel contacts the outer side of the winding shaft. The conveying direction of the finished film material is consistent with the rotation direction of the winding shaft. As the winding shaft rotates, it drives the tape at the end of the finished film material. The tape passes smoothly between the outer side of the pressing wheel and the outer side of the winding shaft, and the tape is firmly attached to the outer side of the winding shaft. The rotating winding shaft can then start the winding operation of the finished film material (at this time, the pressing wheel assembly is immediately retracted without affecting the normal winding operation of the winding shaft).

[0012] Furthermore, the pressing wheel unit is installed on the wheel frame of the guide wheel unit through an elastic buffer assembly.

[0013] By setting up an elastic buffer component, the outer side of the pressing wheel in the pressing wheel unit cooperates with the outer side of the winding shaft to form a certain pressing force. When the tape at the end of the finished film material passes between the two, it ensures that the tape is firmly bonded to the outer side of the winding shaft, avoiding the tape from falling off due to loose bonding.

[0014] Furthermore, the adhesive tape assembly is fixedly mounted on the wheel frame of the guide wheel unit through a side arm, the wheel frame of the guide wheel unit is adjustably mounted on a support plate, the support plate is connected to the adjustment end of the height adjustment assembly, and the guide wheel unit, the pressing wheel unit and the adhesive tape assembly can all be adjusted in position along the width direction of the finished film material.

[0015] The tape application component and the pressing wheel unit are integrated and installed on the wheel frame of the guide wheel unit. Through a height adjustment component (such as a screw drive component), the three components can be driven to extend or retract synchronously, which is more convenient to operate. In addition, by setting a position adjustment component between the wheel frame of the guide wheel unit and the support plate, the position of the guide wheel unit, the pressing wheel unit and the tape application component can be adjusted according to the width of the finished film material to be rolled. The position adjustment component can adopt a structural component with a linear adjustment function in the prior art, such as a structure in which an adjustment slide, a slider and a locking member cooperate.

[0016] Furthermore, the adhesive tape assembly includes a supporting component, an end surface of the supporting component is provided with an air suction port, and the air suction port, the guide wheel in the guide wheel unit, and the pressing wheel in the pressing wheel unit are all facing the same side of the finished film material.

[0017] During specific application, the back side of the tape is sucked through the suction port on the end face of the supporting component, and the adhesive layer of the tape is exposed. As the end of the finished membrane material enters the tape sticking assembly, the exposed adhesive layer of the tape is directly adhered to one side surface of the end of the finished membrane material. The finished membrane material adhered with the tape is then continuously conveyed backward to the guide wheel and the pressing wheel, and the back side of the tape contacts the outer side of the guide wheel and the pressing wheel, and the adhesive layer of the tape is exposed, which facilitates the subsequent cooperation between the outer side of the pressing wheel and the outer side of the winding shaft to smoothly bond the tape to the outer side of the winding shaft.

[0018] Furthermore, the automatic winding device for finished film materials also includes a support plate assembly, which includes a mounting seat, a first support plate and a second support plate. The mounting seat is arranged at the outlet end of the cutting assembly, and the first support plate and the second support plate are arranged on the same side of the mounting seat. The two adhesive tape positioning devices are respectively used in conjunction with the first support plate and the second support plate. One end of the first support plate and the second support plate is located at the outlet end of the cutting assembly, and the other end extends to the corresponding adhesive tape positioning device.

[0019] Since there is a certain distance between the cutting assembly and the two tape positioning devices, a support plate assembly is required to support and guide the end of the finished film material. The end of the finished film material formed after cutting by the cutting assembly is guided and transported to the corresponding tape positioning device.

[0020] Since the equipment in the present application can automatically switch between the two working states of clockwise automatic winding and counterclockwise automatic winding, two tape positioning devices are also provided correspondingly (which can be respectively recorded as a clockwise tape positioning device and a counterclockwise tape positioning device). Therefore, a first support plate and a second support plate are also provided in the support plate assembly, which are used in conjunction with the two tape positioning devices. In a specific embodiment, the first support plate is used in conjunction with the clockwise tape positioning device, and the second support plate is used in conjunction with the counterclockwise tape positioning device. Specifically, according to the working state of the winding shaft, if the winding shaft is in the clockwise automatic winding state, the end of the finished film material formed after the cutting action of the cutting component is pulled into the first support plate under the action of the robot, and is supported and guided by the first support plate, and the end of the finished film material is transported to the clockwise tape positioning device for operation; if the winding shaft is in the counterclockwise automatic winding state, the end of the finished film material formed after the cutting action of the cutting component is pulled into the second support plate under the action of the robot, and is supported and guided by the second support plate, and the end of the finished film material is transported to the counterclockwise tape positioning device for operation.

[0021] Furthermore, the first supporting plate and the second supporting plate are mounted on the mounting seat in an adjustable manner, and the first supporting plate and the second supporting plate can be adjusted in position along the width direction of the finished film material.

[0022] For finished membrane materials of different widths, the positions of the first supporting plate and the second supporting plate can be adjusted accordingly, making the equipment more adaptable.

[0023] Furthermore, two winding shafts are installed on the front of the turntable, the winding shafts are close to the front edge of the turntable, and the winding shafts are located on a circumferential surface that is cocentric with the turntable.

[0024] Due to the limited size of the turntable, in order to ensure that the finished material roll wound on the outside of each winding shaft has a sufficient diameter, and at the same time to realize continuous automatic winding operation without stopping the machine, preferably, two winding shafts are installed on the front of the turntable, and the installation position of the winding shaft is specifically set. The rotation of the turntable can drive the winding shaft to move accurately to a specific position, so that the winding shaft can be used in conjunction with the corresponding tape positioning device.

[0025] Furthermore, the cutting assembly comprises two cutting rollers arranged side by side, the two cutting rollers are respectively mounted on the mounting panel via a first fixing seat and a second fixing seat, and the two cutting rollers can move towards or away from each other.

[0026] When the finished film material on a winding shaft is wound to a specific diameter, the two cutting rollers in the cutting assembly need to cooperate to cut the finished film material. Since the finished film material is produced without stopping the machine, the finished film material is continuously transported backward. The cut finished film material needs to be further transported backward to another winding shaft for winding. At this time, the two cutting rollers are controlled to separate without affecting the backward conveying process of the finished film material.

[0027] Compared with the prior art, the utility model has the following beneficial effects:

[0028] The first drive assembly is controlled to drive the winding shaft to switch freely between clockwise rotation and counterclockwise rotation, and the winding shaft can be controlled to perform clockwise winding operation or counterclockwise winding operation according to the characteristics of the finished film material. The turntable is driven to rotate by the second drive assembly, and the winding shaft on the turntable moves to a position close to the corresponding adhesive tape positioning device for cooperation. Through the cooperation of the cutting assembly and the adhesive tape positioning device, the continuous automatic winding operation of the finished film material is realized. The specific working principle is that when the finished film material on a winding shaft is wound to a specific diameter, the cutting assembly is used to cut the finished film material, and the end of the finished film material moves and enters the corresponding adhesive tape positioning device. The adhesive tape positioning device adheres adhesive tape to the end of the finished film material and adheres and positions the adhesive tape to the outside of another vacant winding shaft, and continues to carry out the winding operation on the winding shaft. Subsequently, the staff member operates to take off the finished film material on the winding shaft that has been wound up, and uses it as an vacant winding shaft. The above operation is repeated to complete the automatic winding operation without stopping the machine. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] like Figure 1-3 As shown, a finished film material automatic winding device includes a mounting panel 1, a turntable 4, a winding shaft 5, a cutting assembly 6, and two tape positioning devices 15;

[0041] A turntable 4, a cutting assembly 6, and two adhesive tape positioning devices 15 are provided on the front of the installation panel 1. At least one winding shaft 5 is installed on the front of the turntable 4. A first driving assembly 2 for driving the winding shaft 5 to switch freely between clockwise rotation and counterclockwise rotation is installed on the back of the turntable 4. A second driving assembly 3 connected to the turntable 4 is provided on the back of the installation panel 1. The second driving assembly 3 drives the turntable 4 to rotate clockwise or counterclockwise. The cutting assembly 6 can cut the finished film material transported inside. The two adhesive tape positioning devices 15 are located near At the edge of the turntable 4, and respectively located on the upper and lower sides of the outlet end of the cutting component 6, the tape positioning device 15 is used to stick tape on the front side of the end of the finished film material and position the tape to the outside of the winding shaft 5. One of the tape positioning devices 15 cooperates with the winding shaft 5 rotating clockwise to wind the finished film material clockwise, which is recorded as the clockwise tape positioning device 16, and the other tape positioning device 15 cooperates with the winding shaft 5 rotating counterclockwise to wind the finished film material counterclockwise, which is recorded as the counterclockwise tape positioning device 17.

[0042] The specific working principle is as follows: according to the characteristics of the finished film material, the first driving component 2 is controlled to drive the winding shaft 5 to switch between clockwise rotation and counterclockwise rotation, so as to control the winding shaft 5 to perform the corresponding clockwise winding operation or counterclockwise winding operation, and the turntable 4 is driven to rotate by the second driving component 3, and the winding shaft 5 on the turntable 4 moves to the position close to the clockwise tape positioning device 16 or the counterclockwise tape positioning device 17 to cooperate, and the finished film material begins to be transported, passes through the cutting component 6, and the tape positioning device 15 is used to stick the tape to the end of the finished film material and stick the tape to the outside of the winding shaft 5, and then starts to be The winding operation is performed on the winding shaft 5 in a clockwise or counterclockwise direction. When the finished film material on a winding shaft 5 is wound to a specific diameter, the finished film material is cut by the cutting component 6, and the end of the finished film material moves and enters the corresponding tape positioning device 15. The tape positioning device 15 sticks tape to the end of the finished film material and positions the tape to the outside of the other empty winding shaft 5, and the winding operation is continued on the winding shaft 5. Subsequently, the staff member operates to take down the finished film material on the winding shaft 5 that has been wound up and uses it as the empty winding shaft 5. The above operation is repeated to complete the automatic winding operation without stopping the machine.

[0043] Among them, Figure 5 As shown, the adhesive tape positioning device 15 includes a mounting frame 18, an adhesive tape assembly 20 and a pressure wheel assembly 21. The mounting frame 18 is arranged on the front of the mounting panel 1. The mounting frame 18 is provided with a height adjustment assembly 19. The adjustment end of the height adjustment assembly 19 is connected to the adhesive tape assembly 20 for pasting the adhesive tape on the end of the finished film material and the pressure wheel assembly 21 for pressing the pasted adhesive tape to and pasting it on the outside of the winding shaft 5. The pressure wheel assembly 21 is located on the side close to the turntable 4. In the prior art, the adhesive is applied to the end of the finished film material by a coating roller, and the coating roller is pressed down to position the end of the finished film material to the outside of the winding shaft 5 through the adhesive. In this way, the end of the finished film material is not firmly combined with the outside of the winding shaft 5. Under the action of the winding traction force, the end of the finished film material is easily separated from the outside of the winding shaft 5, and the outside of the winding shaft 5 is easily contaminated. In the present application, the specific structure of the tape positioning device 15 is designed, and the height adjustment component 19 is used to drive the tape assembly 20 and the pressure wheel assembly 21 to extend. When the end of the finished film material passes through the tape assembly 20, the tape assembly 20 sticks the tape to the end of the finished film material, and the finished film material is transported backward to the pressure wheel assembly 21. The wheel body in the pressure wheel assembly 21 contacts the back of the tape, and presses and sticks the adhesive layer of the tape to the corresponding outer side of the winding shaft 5, and then the height adjustment component 19 drives the tape assembly 20 and the pressure wheel assembly 21 to retract, so that the finished film material can be wound up normally.

[0044] Specifically, Figure 4As shown, the pressing wheel assembly 21 includes a guide wheel unit 22 and a pressing wheel unit 23, both of which are connected to the adjustment end of the height adjustment assembly 19, and the guide wheel unit 22 is located between the tape assembly 20 and the pressing wheel unit 23. The height adjustment assembly 19 controls the pressing wheel in the pressing wheel unit 23 to extend out of the mounting frame 18 until the outer side of the pressing wheel contacts the outer side of the winding shaft 5. Whether to set up the guide wheel unit 22 can be determined according to specific usage needs. When the conveying direction of the finished film material is not suitable for being directly introduced into the position where the outer side of the pressing wheel contacts the outer side of the winding shaft 5, it is necessary to use the guide wheel in the guide wheel unit 22 and the pressing wheel in the pressing wheel unit 23 to form a directional guidance for the conveying direction of the finished film material. The end of the finished film material can be smoothly introduced into the position where the outer side of the pressing wheel contacts the outer side of the winding shaft 5. The conveying direction of the finished film material is consistent with the rotation direction of the winding shaft 5. As the winding shaft 5 rotates, it drives the tape at the end of the finished film material. The tape passes smoothly between the outer side of the pressing wheel and the outer side of the winding shaft 5, and the tape is firmly attached to the outer side of the winding shaft 5. The rotating winding shaft 5 can then start the winding operation of the finished film material (at this time, the pressing wheel assembly 21 is immediately retracted without affecting the normal winding operation of the winding shaft 5).

[0045] Specifically, the pressing wheel unit 23 is installed on the wheel frame of the guide wheel unit 22 through the elastic buffer component 24. By setting the elastic buffer component 24, the outer side of the pressing wheel in the pressing wheel unit 23 cooperates with the outer side of the winding shaft 5 to form a certain elastic pressing force. When the adhesive tape at the end of the finished film passes between the two, it is ensured that the adhesive tape is firmly bonded to the outer side of the winding shaft 5, avoiding the situation where the adhesive tape falls off due to loose bonding. In addition, the pressing wheel in the pressing wheel unit 23 forms an elastic contact force with the outer side of the winding shaft 5, which is not easy to cause damage to the end of the finished film.

[0046] Specifically, the adhesive tape assembly 20 is fixedly mounted on the wheel frame of the guide wheel unit 22 through the side arm, and the wheel frame of the guide wheel unit 22 is positionally adjustable and mounted on the support plate 25, and the support plate 25 is connected to the adjustment end of the height adjustment assembly 19, and the guide wheel unit 22, the pressing wheel unit 23 and the adhesive tape assembly 20 can all be adjusted in position along the width direction of the finished film material. The adhesive tape assembly 20 and the pressing wheel unit 23 are integrated and installed on the wheel frame of the guide wheel unit 22, and the three components can be driven to extend or retract synchronously through a height adjustment assembly 19 (such as a screw drive assembly), which makes it more convenient to operate. In addition, by arranging a position adjustment assembly between the wheel frame of the guide wheel unit 22 and the support plate 25, the positions of the guide wheel unit 22, the pressing wheel unit 23 and the adhesive tape assembly 20 are adjusted according to the width of the finished film material to be rolled. The position adjustment assembly can adopt a structural assembly with a linear adjustment function in the prior art, such as a structure in which an adjustment slide, a slider and a locking member cooperate.

[0047] Specifically, the adhesive tape assembly 20 includes a support component, and an air suction port is provided on the end face of the support component. The air suction port, the guide wheel in the guide wheel unit 22, and the pressing wheel in the pressing wheel unit 23 are all facing the same side of the finished film material. In specific applications, the back side of the tape is adsorbed through the air suction port on the end face of the support component, and the adhesive layer of the tape is exposed. As the end of the finished film material enters the adhesive tape assembly 20, the exposed adhesive layer of the tape is directly adhered to one side of the end of the finished film material, and then the finished film material adhered with the tape continues to be transported backward to the guide wheel and the pressing wheel, and the back side of the tape contacts the outer side of the guide wheel and the pressing wheel, and the adhesive layer of the tape is exposed, which facilitates the subsequent cooperation between the outer side of the pressing wheel and the outer side of the winding shaft 5, so that the tape is smoothly adhered to the outer side of the winding shaft 5.

[0048] Among them, Figure 1 and Figure 7As shown, the finished film material automatic winding device also includes a support plate assembly 11, which includes a mounting seat 12, a first support plate 13 and a second support plate 14. The mounting seat 12 is arranged at the outlet end of the cutting assembly 6, and the first support plate 13 and the second support plate 14 are arranged on the same side of the mounting seat 12. Two adhesive tape positioning devices 15 are respectively used in conjunction with the first support plate 13 and the second support plate 14. One end of the first support plate 13 and the second support plate 14 is located at the outlet end of the cutting assembly 6, and the other end extends to the corresponding adhesive tape positioning device 15. Since there is a certain distance between the cutting assembly 6 and the two adhesive tape positioning devices 15, the support plate assembly 11 is required to support and guide the end of the finished film material, and the end of the finished film material formed after the cutting action of the cutting assembly 6 is directed and guided and transported to the corresponding adhesive tape positioning device 15. Since the equipment in the present application can automatically switch between the two working states of clockwise automatic winding and counterclockwise automatic winding, two tape positioning devices 15 (clockwise tape positioning device 16, counterclockwise tape positioning device 17) are also provided accordingly. Therefore, a first supporting plate 13 and a second supporting plate 14 are also provided correspondingly in the supporting plate assembly 11, which are used in conjunction with the two tape positioning devices 15. In a specific embodiment, the first supporting plate 13 is used in conjunction with the clockwise tape positioning device 16, and the second supporting plate 14 is used in conjunction with the counterclockwise tape positioning device 17. Specifically, according to the working state of the winding shaft 5, if the winding shaft 5 is in the clockwise automatic winding state, the end of the finished film material formed by the cutting action of the cutting component 6 is pulled into the first supporting plate 13 under the action of the robot, and is supported and guided by the first supporting plate 13, and the end of the finished film material is transported to the clockwise tape positioning device 16 for operation; if the winding shaft 5 is in the counterclockwise automatic winding state, the end of the finished film material formed by the cutting action of the cutting component 6 is pulled into the second supporting plate 14 under the action of the robot, and is supported and guided by the second supporting plate 14, and the end of the finished film material is transported to the counterclockwise tape positioning device 17 for operation.

[0049] Specifically, the first support plate 13 and the second support plate 14 are mounted on the mounting seat 12 in an adjustable position, and the first support plate 13 and the second support plate 14 can be adjusted in position along the width direction of the finished film material. For finished film materials of different widths, the positions of the first support plate 13 and the second support plate 14 can be adjusted accordingly, and the applicability of the equipment is stronger. Slide blocks are provided at the bottom of the first support plate 13 and the second support plate 14, and two linear slide rails are provided on the mounting seat 12. The slide blocks are slidably mounted on the corresponding linear slide rails, and the locking bolts pass through the slide blocks and are fastened to the outside of the linear slide rails.

[0050] In a specific embodiment, two reel shafts 5 are installed on the front of the turntable 4, the reel shafts 5 are close to the front edge of the turntable 4, and the reel shafts 5 are located on a circumferential surface that is concentric with the turntable 4. Since the size of the turntable 4 is limited, in order to ensure that the finished material roll reeled on the outside of each reel shaft 5 has a sufficient diameter and to achieve continuous automatic reeling without stopping the machine, preferably, two reel shafts 5 are installed on the front of the turntable 4, and the installation position of the reel shaft 5 is specifically set, and the rotation of the turntable 4 can drive the reel shaft 5 to move accurately to a specific position, so that the reel shaft 5 is used in conjunction with the corresponding tape positioning device 15.

[0051] Among them, Figure 6 As shown, the cutting assembly 6 includes two cutting rollers 7 arranged side by side. The two cutting rollers 7 are respectively installed on the installation panel 1 through the first fixing seat 8 and the second fixing seat 9. The two cutting rollers 7 can move toward or away from each other. When the finished film material on a winding shaft 5 is wound to a specific diameter, the two cutting rollers 7 in the cutting assembly 6 need to cooperate to cut the finished film material. Since the finished film material is produced without stopping the machine, the finished film material is continuously transported backwards. The cut finished film material needs to continue to be transported backwards to another winding shaft 5 for winding. At this time, the two cutting rollers 7 are controlled to separate without affecting the backward conveying process of the finished film material.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
