Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, specifically to an automatic film-removing device for TP protective film. Background Technology

[0002] The industry commonly uses a protective film applied to the surface of mobile phones to protect them from external environmental damage. This film is then removed in the next processing step. Existing automatic film removal methods generally include using grippers to hold the film, using adhesive tape to peel it off, or using suction cups to pick it up. However, all of these methods have limitations. For example, the grippers of the gripper device and the adhesive head that holds the tape to the phone can collide with the phone's surface during operation, potentially causing damage. Furthermore, while existing tape-peeling devices can easily remove soft films, when removing hard films, the greater curvature at the end may cause the hard film to detach from the tape, or the adhesive force may be insufficient. In cases where a hard screen protector is bent and damages the phone, the only way to remove it is by suction cup. However, suction cups can malfunction when used with soft screen protectors due to deformation. In practice, various types of protective films are used depending on the shape of the phone being processed or its stage of processing, such as soft protective films, hard protective films, and TP protective films with an upper layer. Therefore, existing processing plants generally have multiple film-removing machines to meet different film-removing needs, which is costly. Especially for TP protective films, which have an upper layer film covering them, the upper layer film needs to be removed before leaving the factory. However, using existing film-removing machines can easily tear off the upper layer film and the TP protective film together during the film-removing process, resulting in poor film-removing effect. Summary of the Invention

[0003] The technical problem to be solved by the present invention is that the existing film-peeling equipment has poor versatility, cannot meet the film-peeling work of various types of protective films, and cannot effectively remove the upper layer of TP protective film, thus having certain limitations.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an automatic film-peeling device for TP protective film, comprising:

[0005] The tape unwinding and winding mechanism is used to supply film-tearable tape and take up waste material;

[0006] The film-removing component is used to pull the film-removing tape to adhere to the upper film of the TP protective film and to pull the upper film of the TP protective film off the mobile phone.

[0007] The carrier conveyor mechanism is used to supply mobile phones with the film to be peeled off, and to transfer mobile phones for work station changes;

[0008] The discharge end of the tape winding and unwinding mechanism is connected to the feed end of the film-tearing assembly, and the take-up end of the tape winding and unwinding mechanism is connected to the discharge end of the film-tearing assembly. The film-tearing assembly is provided with a film-tearing part for moving the film-tearing tape to adhere to the upper layer of the TP protective film. When performing the film-tearing operation, the film-tearing part of the film-tearing assembly moves the film-tearing tape into the transfer path of the mobile phone in the carrier conveying mechanism, and drives the film-tearing tape to adhere to the upper layer of the TP protective film on the mobile phone according to a preset adhesion angle. After the film-tearing tape adheres to the upper layer of the TP protective film, the film-tearing part of the film-tearing assembly moves and drives the upper layer of the TP protective film to detach from the mobile phone.

[0009] When in operation, this invention can automatically supply and rewind the film-peeling tape, automatically supply and transport the mobile phone, peel off the adhesion of the upper film of the TP protective film, and adaptively adjust the adhesion angle, achieving full automation of the film-peeling process and ensuring high film-peeling efficiency. At the same time, it can dynamically adjust the adhesion angle according to the state of the upper film of the TP protective film, ensuring that the film-peeling tape can accurately contact the upper film of the TP protective film and effectively peel off the upper film. It can be used to peel off the upper film of TP protective films with various edge states and hardness without additional adjustments, and has a wide range of applications and good versatility.

[0010] Preferably, the film-tearing assembly further includes a first driving part for driving the film-tearing part to move and an angle adjusting part for cooperating with the film-tearing part to adjust the angle of the film-tearing tape. The film-tearing part and the angle adjusting part of the film-tearing assembly are arranged sequentially along the direction of extension of the film-tearing tape. The film-tearing part of the film-tearing assembly moves under the drive of the first driving part and cooperates with the angle adjusting part to adjust the angle of the film-tearing tape when performing the film-tearing work to achieve the adjustment of the adhesion angle.

[0011] Preferably, the film-peeling assembly further includes a second driving part for driving the film-peeling part to move along the extension direction of the upper film of the TP protective film. Under the drive of the second driving part, the film-peeling part of the film-peeling assembly moves along the extension direction of the upper film of the TP protective film, and drives the film-peeling tape of the upper film that is not attached to the TP protective film to be attached to each part of the upper film of the TP protective film in sequence, and drives the film-peeling tape of the upper film that is attached to the TP protective film to move away from the mobile phone.

[0012] When this invention is in operation, by setting the angle adjustment part and the film-tearing part to cooperate with each other, the control precision of the adhesion angle can be further improved, ensuring that the film-tearing tape adheres to the upper film of the TP protective film in the best mechanical state. It has high versatility and high film-tearing quality. At the same time, the film-tearing part drives the film-tearing tape to adhere to each part of the upper film of the TP protective film in sequence, and drives the film-tearing tape of the already adhered upper film of the TP protective film to move away from the mobile phone. It can smoothly and thoroughly peel off the upper film of the TP protective film, while avoiding damage to the mobile phone or breakage of the upper film of the TP protective film due to excessive instantaneous pulling force, thus ensuring the stability of the film-tearing work.

[0013] Preferably, the film-tearing assembly includes a first film-tearing roller for winding film-tearing tape, a second film-tearing roller for winding waste material, a film-tearing roller, a film-tearing lifting drive device, and a translation drive device. The first film-tearing roller is rotatably arranged at the feed end of the film-tearing assembly, and the second film-tearing roller is rotatably arranged at the discharge end of the film-tearing assembly. The film-tearing roller is arranged between the first and second film-tearing rollers and above the film-tearing tape's movement path. The film-tearing roller is driven by the output part of the film-tearing lifting drive device and, driven by the film-tearing lifting drive device, moves the film-tearing tape into the mobile phone's transport path in the carrier conveyor mechanism. The film-tearing roller is driven by the output part of the translation drive device and, driven by the translation drive device, moves along the extension direction of the upper layer of the TP protective film, causing the film-tearing tape of the upper layer of the TP protective film that is not adhered to the TP protective film to sequentially adhere to each part of the upper layer of the TP protective film, and causing the film-tearing tape of the upper layer of the TP protective film that has been adhered to the TP protective film to move away from the mobile phone.

[0014] Preferably, the film-tearing assembly further includes an angle adjusting roller for adjusting the angle of the film-tearing tape. The angle adjusting roller is adjustablely arranged between the film-tearing roller and the second film-tearing roller, and is located above the moving path of the film-tearing tape. The film-tearing roller moves under the drive of the film-tearing lifting drive device and cooperates with the angle adjusting roller to adjust the angle of the film-tearing tape when performing the film-tearing operation, so as to adjust the adhesion angle.

[0015] Preferably, the film-peeling assembly further includes a flat roller assembly for rolling the phone after peeling off the film. The flat roller assembly includes a flat roller and a flat roller lifting drive device. The flat roller is vertically and vertically arranged on one side of the film-peeling roller. The flat roller is driven by the output part of the flat roller lifting drive device and abuts against the corresponding protective film of the phone under the drive of the flat roller lifting drive device. The flat roller is driven by the output part of the translation drive device and rolls the protective film of the phone under the drive of the translation drive device.

[0016] When the present invention is working, by setting a flat rolling component to roll the TP protective film on the surface of the mobile phone after the film is peeled off, the connection strength of the TP protective film can be improved and any air bubbles that may exist can be expelled, making it more adherent and flatter.

[0017] Preferably, the tearing part of the tearing assembly is provided with at least two adhesive parts for driving the tearing tape to adhere to the upper film of the TP protective film. The adhesive parts of the tearing assembly are arranged sequentially along the extension direction of the tearing tape and kept parallel. When performing the tearing operation, the adhesive parts of the tearing assembly drive the tearing tape to press against the upper film of the TP protective film by rolling sequentially.

[0018] In operation, this invention uses multiple adhesive sites to sequentially roll the tear-off tape, allowing the tape to adhere to the upper layer of the TP protective film with progressive and uniform pressure. This reduces air bubbles between the tape and the upper layer, increasing the contact area and improving adhesion. Even the upper layer of a large-area or strongly adhesive TP protective film can be reliably adhered and torn off, thus improving the reliability of the tear-off process.

[0019] Preferably, the tape take-up and unwrap mechanism is provided with a tension adjustment mechanism, which includes a tension adjustment roller, a pressure block, and a pressure drive device. The tension adjustment roller is arranged at the discharge end of the tape take-up and unwrap mechanism. The pressure block extends along the axial direction of the tension adjustment roller and cooperates with the tension adjustment roller to form a gap for the tear-off tape to pass through. The pressure block is driven by the output part of the pressure drive device and drives the tear-off tape to press against the tension adjustment roller under the drive of the pressure drive device.

[0020] Preferably, the carrier conveying mechanism includes a carrier for mounting a mobile phone and a positioning mechanism for positioning the mobile phone during the film-tearing operation. The positioning mechanism includes a positioning frame, a carrier positioning device, a carrier limiting device, and a first conveying device. The carrier positioning device and the first conveying device are both mounted on the positioning frame. The positioning frame has a film-tearing station for placing the carrier. The film-tearing station of the positioning frame is aligned with the film-tearing part of the film-tearing assembly. When the carrier is input, it is driven to the output part of the first conveying device and moves to the film-tearing station under the drive of the first conveying device. The carrier limiting device is arranged at the discharge end of the positioning mechanism. Before the carrier is input, the limiting part of the carrier limiting device moves to the movement path of the carrier in the positioning mechanism and abuts against the carrier when the carrier is input to limit the carrier in the film-tearing station. After the carrier is input, the output part of the carrier positioning device moves to the film-tearing station and abuts against the carrier to fix the carrier in the film-tearing station.

[0021] Preferably, the carrier conveying mechanism further includes a mobile phone fixing device for fixing the mobile phone during the film-removing operation. The fixing part of the mobile phone fixing device is connected to the mobile phone installed on the carrier after the carrier is fixed, and is separated from the mobile phone installed on the carrier after the film-removing operation is completed.

[0022] The beneficial technical effects of this invention include:

[0023] 1. This invention enables automatic supply and winding of the film-peeling tape, automatic supply and conveying of the mobile phone, adhesion and removal of the upper film of the TP protective film, and adaptive adjustment of the adhesion angle, achieving full automation of the film-peeling process and ensuring high film-peeling efficiency. Simultaneously, it can dynamically adjust the adhesion angle according to the state of the upper film of the TP protective film, ensuring that the film-peeling tape accurately contacts and effectively peels off the upper film of the TP protective film. It is applicable to peeling the upper film of TP protective films with various edge conditions and hardness without additional adjustments, making it widely applicable and versatile.

[0024] 2. This invention, by setting the angle adjustment part and the film-peeling part to cooperate with each other, can further improve the control accuracy of the adhesion angle, ensuring that the film-peeling tape adheres to the upper film of the TP protective film in the best mechanical state. It has high versatility and high film-peeling quality. At the same time, the film-peeling part drives the film-peeling tape to adhere to each part of the upper film of the TP protective film in sequence, and drives the film-peeling tape of the already adhered upper film of the TP protective film to move away from the mobile phone. It can smoothly and thoroughly peel off the upper film of the TP protective film, while avoiding damage to the mobile phone or breakage of the upper film of the TP protective film due to excessive instantaneous pulling force, thus ensuring the stability of the film-peeling work.

[0025] 3. By setting a flat rolling component to roll the TP protective film on the surface of the mobile phone after the film is peeled off, the present invention can improve the connection strength of the TP protective film and remove any possible air bubbles, making it more adherent and flatter.

[0026] 4. This invention sets up multiple adhesive areas to sequentially roll the tear-off tape, allowing the tear-off tape to be pressed against the upper layer of the TP protective film with progressive and uniform pressure. This reduces air bubbles between the tear-off tape and the upper layer of the TP protective film, thereby increasing the contact area between the tear-off tape and the upper layer of the TP protective film and improving the adhesion. Even the upper layer of the TP protective film, which has a large area or strong adhesion, can be reliably adhered and torn off, improving the reliability of the tear-off process.

[0039] The technical solutions of the embodiments of the present invention will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present invention.

[0040] In the following description, terms such as “inner,” “outer,” “upper,” “lower,” “left,” and “right” are used only to indicate orientation or positional relationship for the convenience of describing the embodiments and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0041] Example 1:

[0042] Please see Figure 1 This embodiment discloses an automatic film-removing device for TP protective film, comprising:

[0043] The tape unwinding and rewinding mechanism 1 is used to supply film-tearing tape and winding waste;

[0044] The film-peeling component 2 is used to drive the film-peeling tape to adhere to the upper film of the TP protective film and to drive the upper film of the TP protective film to detach from the mobile phone.

[0045] The carrier conveying mechanism 3 is used to supply mobile phones with the film to be peeled off, and to transfer mobile phones for work station changes;

[0046] The discharge end of the tape winding and unwinding mechanism 1 is connected to the feed end of the film-tearing assembly 2, and the take-up end of the tape winding and unwinding mechanism 1 is connected to the discharge end of the film-tearing assembly 2. The film-tearing assembly 2 is provided with a film-tearing part for moving the film-tearing tape to adhere to the upper layer of the TP protective film. When performing the film-tearing operation, the film-tearing part of the film-tearing assembly 2 moves the film-tearing tape into the mobile phone's transport path in the carrier conveying mechanism 3, and drives the film-tearing tape to adhere to the upper layer of the TP protective film on the mobile phone according to the preset adhesion angle. During operation, it is necessary to preset a matching adhesion angle according to the edge state of the mobile phone being processed, so that the film-tearing tape can adhere tightly to the edge position of the upper layer of the TP protective film, thereby effectively reducing the tearing force of the upper layer of the TP protective film. After the film-tearing tape adheres to the upper layer of the TP protective film, the film-tearing part of the film-tearing assembly 2 moves and drives the upper layer of the TP protective film to detach from the mobile phone.

[0047] In operation, this embodiment can automatically supply and rewind the film-peeling tape, automatically supply and transport the mobile phone, peel off the upper layer of the TP protective film, and adaptively adjust the adhesion angle, achieving full automation of the film-peeling process. It can ensure high film-peeling efficiency and dynamically adjust the adhesion angle according to the state of the upper layer of the TP protective film, ensuring that the film-peeling tape can accurately contact the upper layer of the TP protective film and effectively peel it off. It can be used to peel off the upper layer of TP protective films with various edge states and hardness without additional adjustments, making it widely applicable and versatile.

[0048] Preferably, the film-peeling assembly 2 further includes a first driving part for driving the film-peeling part to move and an angle adjusting part for cooperating with the film-peeling part to adjust the angle of the film-peeling tape. The film-peeling part and the angle adjusting part of the film-peeling assembly 2 are arranged sequentially along the extension direction of the film-peeling tape. The film-peeling part of the film-peeling assembly 2 moves under the action of the first driving part and cooperates with the angle adjusting part to adjust the angle of the film-peeling tape when performing the film-peeling work to achieve the adjustment of the adhesion angle. In actual work, due to the large number of mobile phones, there are various shapes of mobile phone edges, such as rounded corners, chamfers, folded edges, etc. Therefore, it is necessary to dynamically adjust the angle of the film-peeling tape so that the film-peeling tape can accurately adhere to the TP protective film. The upper film is adhered to the edge of the film. Of course, the angle of the film-tearing tape can also be adjusted in real time according to the curvature change of the upper film of the TP protective film when moving the film-tearing part. Thus, the upper film of the TP protective film is gradually peeled off from the edge of the TP protective film by bending. This can effectively reduce the driving force required to remove the upper film of the TP protective film. In specific implementation, the position of the angle adjustment part of the film-tearing component 2 can also be set to adjustable. By further increasing the angle adjustment range of the film-tearing tape when performing film-tearing work, the applicability of the fully automatic film-tearing machine can be further improved. Only a few adjustments are needed to complete the equipment debugging work, saving a lot of manpower and resources.

[0049] In practical implementation, the film-peeling assembly 2 also includes a second driving part for driving the film-peeling part to move along the extension direction of the upper layer of the TP protective film. Under the drive of the second driving part, the film-peeling part of the film-peeling assembly 2 moves along the extension direction of the upper layer of the TP protective film, and drives the film-peeling tape of the upper layer of the TP protective film that is not attached to it to stick to each part of the upper layer of the TP protective film in sequence, and drives the film-peeling tape of the upper layer of the TP protective film that is attached to it to move away from the mobile phone at a preset film-peeling angle. In practical implementation, the film-peeling angle can be adjusted according to the state of the upper layer of the TP protective film, which can avoid the situation where the upper layer of the TP protective film separates from the film-peeling tape due to its large curvature, and can effectively improve the success rate of film-peeling.

[0050] In this embodiment, by setting the angle adjustment part and the film-tearing part to work together, the control precision of the adhesion angle can be further improved, ensuring that the film-tearing tape adheres to the upper film of the TP protective film in the best mechanical state. It has high versatility and high film-tearing quality. At the same time, the film-tearing part drives the film-tearing tape to adhere to each part of the upper film of the TP protective film in sequence, and drives the film-tearing tape of the already adhered upper film of the TP protective film to move away from the mobile phone. It can smoothly and thoroughly peel off the upper film of the TP protective film, while avoiding damage to the mobile phone or breakage of the upper film of the TP protective film due to excessive instantaneous pulling force, thus ensuring the stability of the film-tearing work.

[0051] As a further improvement of this embodiment, the tearing part of the film-tearing assembly 2 is provided with at least two adhesive parts for driving the film-tearing tape to adhere to the upper film of the TP protective film. Several adhesive parts of the film-tearing assembly 2 are arranged sequentially along the extension direction of the film-tearing tape and kept parallel. When performing the film-tearing operation, the adhesive parts of the film-tearing assembly 2 drive the film-tearing tape to press against the upper film of the TP protective film by rolling sequentially.

[0052] In this embodiment, by setting multiple adhesive areas and rolling the tear-off tape sequentially, the tear-off tape can be pressed against the upper layer of the TP protective film with gradual and uniform pressure. This reduces air bubbles between the tear-off tape and the upper layer of the TP protective film, thereby increasing the contact area between the tear-off tape and the upper layer of the TP protective film and improving the adhesion. Even the upper layer of the TP protective film, which has a large area or strong adhesion, can be reliably adhered and torn off, thus improving the reliability of the tear-off operation.

[0053] Example 2:

[0054] Please see Figures 1 to 10 This embodiment provides an automatic film-removing device for TP protective film. The similarities with other embodiments will not be repeated. The differences will be described in detail below.

[0055] In this embodiment, the film-tearing assembly 2 includes a first film-tearing roller 201 for winding film-tearing tape, a second film-tearing roller 202 for winding waste material, a film-tearing roller 203, a film-tearing lifting drive device 204, and a translation drive device 205. The first film-tearing roller 201 is rotatably arranged at the feed end of the film-tearing assembly 2, and the second film-tearing roller 202 is rotatably arranged at the discharge end of the film-tearing assembly 2. The film-tearing roller 203 is arranged between the first film-tearing roller 201 and the second film-tearing roller 202, and is located above the moving path of the film-tearing tape. The film-tearing roller 203 is connected to the film-tearing lifting drive device 204. The output part of device 204 is driven and, driven by the film-tearing lifting drive device 204, moves the film-tearing tape into the mobile phone transfer path in the carrier conveying mechanism 3. The film-tearing roller 203 is driven and connected to the output part of the translation drive device 205. Under the drive of the translation drive device 205, the film-tearing roller 203 moves along the extension direction of the upper film of the TP protective film, and drives the film-tearing tape of the upper film that is not attached to the TP protective film to be attached to each part of the upper film of the TP protective film in sequence, and drives the film-tearing tape of the upper film that has been attached to the TP protective film to move away from the mobile phone.

[0056] Preferably, the film-tearing assembly 2 further includes an angle adjusting roller 206 for adjusting the angle of the film-tearing tape. The angle adjusting roller 206 is adjustablely arranged between the film-tearing roller 203 and the second film-tearing roller 202, and is located above the moving path of the film-tearing tape. The film-tearing roller 203 is driven by the film-tearing lifting drive device 204 and cooperates with the angle adjusting roller 206 to adjust the angle of the film-tearing tape when performing the film-tearing operation, so as to adjust the adhesion angle.

[0057] In specific implementation, the film-tearing assembly 2 also includes a first roller mounting base 208, a film-tearing frame 209, a first film-tearing translational slide rail 210, and a second film-tearing translational slide rail 211. The first film-tearing translational slide rail 210 and the second film-tearing translational slide rail 211 are arranged parallel to each other along the direction of the film-tearing tape extension. The two ends of the film-tearing frame 209 are slidably and limitedly mounted on the first film-tearing translational slide rail 210 and the second film-tearing translational slide rail 211, respectively. The film-tearing roller 203 is vertically and flexibly mounted on the film-tearing frame 209 via the first roller mounting base 208. The film-tearing frame 209 is connected to the translational drive device via a transmission assembly. The output part of 205 is connected to the transmission. The film-tearing frame 209 moves along the extension direction of the upper film of the TP protective film under the drive of the translation drive device 205. The first film-tearing roller 201, the film-tearing roller 203, the angle adjustment roller 206, and the second film-tearing roller 202 are rotatably mounted on the film-tearing frame 209 in sequence along the extension direction of the film-tearing tape. As a further improvement of this embodiment, there are two film-tearing rollers 203, which can further improve the rolling efficiency, ensure that the film-tearing tape and the upper film of the TP protective film are tightly bonded, and reduce the risk of the upper film of the TP protective film detaching from the film-tearing tape.

[0058] In this embodiment, in order to be suitable for the tearing process of the TP protective film with the upper film, it is necessary to roll the TP protective film after tearing. The tearing assembly 2 also includes a flat rolling assembly 207 for rolling the mobile phone after tearing. The flat rolling assembly 207 includes a flat rolling roller 2071 and a flat rolling lifting drive device 2072. The flat rolling roller 2071 is arranged vertically on one side of the tearing roller 203. The flat rolling roller 2071 is connected to the output part of the flat rolling lifting drive device 2072 and is driven by the flat rolling lifting drive device 2072 to roll the TP protective film. The corresponding protective film of the mobile phone is abutted, and the flat roller 2071 is connected to the output part of the translation drive device 205 for transmission. Under the drive of the translation drive device 205, the protective film of the mobile phone is rolled. In specific implementation, the film peeling assembly 2 also includes a second roller mounting seat 212. The flat roller 2071 is mounted on the film peeling frame 209 in a height-reducing manner through the second roller mounting seat 212, which can improve the stability during rolling. Preferably, the flat roller 2071 can also be made of flexible material to avoid damage to the surface of the mobile phone.

[0059] In this embodiment, by setting the flat rolling component 207 to roll the TP protective film on the surface of the mobile phone after the film is peeled off, the connection strength of the TP protective film can be improved, and any air bubbles that may exist can be expelled, making it more adherent and flatter.

[0060] In specific implementation, the tape take-up and unwinding mechanism 1 is provided with a tension adjustment mechanism 11. The tension adjustment mechanism 11 includes a tension adjustment roller 111, a film pressing block 112, and a film pressing drive device 113. The tension adjustment roller 111 is arranged at the discharge end of the tape take-up and unwinding mechanism 1. The film pressing block 112 extends along the axial direction of the tension adjustment roller 111 and cooperates with the tension adjustment roller 111 to form a gap for the tearing tape to pass through. The film pressing block 112 is connected to the output part of the film pressing drive device 113 and drives the tearing tape to press against the tension adjustment roller 111 under the drive of the film pressing drive device 113.

[0061] In this embodiment, the system also includes a mounting frame 4. The tape unwinding and winding mechanism 1 further includes a film unwinding mechanism 12 for supplying tear-off tape and a film winding mechanism 13 for winding waste material. The film unwinding mechanism 12 is provided with a film unwinding roller 121 for winding the tear-off tape and a film unwinding drive device 122 for driving the film unwinding roller 121 to rotate. The film unwinding roller 121 is rotatably mounted on one side of the top of the mounting frame 4 and is driven by a transmission assembly to the output part of the film unwinding drive device 122. The film winding mechanism 13 is provided with a film winding roller 131 for winding waste material and a film winding drive device 132 for driving the film winding roller 131 to rotate. The film winding roller 131 is rotatably mounted on the other side of the top of the mounting frame 4 and is driven by a transmission assembly to the output part of the film winding drive device 122. The moving component is connected to the output of the film take-up drive device 132. In specific implementation, a film take-up sensor can also be added around the take-up roller. When the thickness of the waste material wound on the take-up roller exceeds the preset threshold, the take-up sensor is triggered, so that the take-up sensor can send a prompt signal to the operator, so that the operator can replace the take-up roller in time. Of course, a length measuring device can also be added at the feed end of the take-up mechanism 13, so that the measuring part of the length measuring device can contact the waste material entering the take-up mechanism 13, thereby counting the length of the waste material being wound. During operation, a stepper motor can be used as the film unwinding drive device 122 and the take-up drive device 132, which can improve the overall control accuracy of the fully automatic film tearing machine.
