Description

Technical Field

[0001] The invention relates to the technical field of conductive film production and processing, in particular to a conductive film die-cutting device. Background Art

[0002] Die cutting refers to a molding process in which a die-cutting knife is used to combine a die-cutting plate according to the pattern required by the product design, and a printed matter or other plate-like blank is rolled and cut into the desired shape or cut under the action of pressure. It is often used in the processing of PC film.

[0003] The main component of PC film is polycarbonate, which is a polymer material with excellent physical and mechanical properties and chemical stability. PC film is made into products of various shapes and sizes through extrusion, embossing, injection molding and other processes, and its thickness is generally between 0.15mm-3mm. The die-cutting equipment is a very important equipment in the production process of PC film. Its function is to cut the material into PC film products according to a certain shape and size through the die-cutting tool.

[0004] As is known, die cutting and punching are generally performed on both sides of the conductive film. The design of punching holes on both sides of the conductive film allows the circuit board to be connected to the outside through the surface without the need for additional connectors or interfaces. This design makes the circuit board more compact and lightweight, and is suitable for the needs of various electronic devices. When die cutting and punching the conductive film, a die cutting device is usually used for the die cutting operation.

[0005] There are many die-cutting devices in the prior art, such as the relevant patent 202322768898.4. The authorization announcement number is CN221089331U, and the name is a die-cutting device for thick PC film. It discloses a die-cutting device for thick PC film, including a base, a lifting assembly is arranged on the top of the base, a punching tool is arranged on the bottom of the lifting assembly, and rectangular plates are fixedly installed at the front and rear edges of the top of the base. The two rectangular plates are fixedly installed on the side close to each other, and a hydraulic cylinder is fixedly installed at the output end of each electric telescopic rod. In the above patent, the punching tool punches the PC film by controlling the lifting assembly to move downward. The two sets of tensioning roller assemblies can adjust the tension of the PC film when the tension of the PC film is loose, and prevent the PC film from being offset during transportation.

[0006] Another example is a Chinese patent with application number 202121379829.9, authorization announcement number CN215848615U, and name "A die-cutting device for thick PC films". The above patent discloses a die-cutting device for thick PC films, including a workbench, a conveyor belt movably installed on the top of the workbench, a drawer movably installed on the front of the workbench, a guide column fixedly installed on the top of the workbench, a top plate fixedly installed on the top of the guide column, an electric push rod fixedly installed on the top of the top plate, the output end of the electric push rod is fixedly connected to a downward pressing mechanism, and a dust removal mechanism is fixedly installed on the front of the workbench.

[0007] In the prior art, such as the above-mentioned patent, the die-cutting efficiency of the conductive film can be improved to a certain extent. It is known that PC film is generally rolled up by a reel for easy storage and transportation. Therefore, when performing the die-cutting operation, the PC film must first be horizontally unfolded at the die-cutting station before the die-cutting operation can be performed. As can be seen from the above-mentioned patent, the die-cutting equipment in the prior art usually uses a driving mechanism to drive the die-cutting knife to slide downward when working, and applies pressure to the PC film for die-cutting operation. After the die-cutting operation is completed, the driving mechanism drives the die-cutting knife to reset upward, and after the PC film slides forward for a certain stroke, the driving mechanism drives the die-cutting knife downward again to perform the die-cutting operation on the PC film, and the die-cutting operation is performed reciprocatingly. When the die-cutting knife slides downward for the die-cutting operation, the die-cutting knife will be in close contact with the PC film. Therefore, when the driving mechanism drives the die-cutting knife to reset upward, the die-cutting knife will continue to be in close contact with the PC film. Since the weight of the PC film is relatively light, the die-cutting knife has the problem of driving the PC film to slide upward together, causing wrinkles in the PC film, which affects the die-cutting quality. Meanwhile, the existing die-cutting generally requires a separate conveying mechanism to drive the PC film to slide forward, which not only requires a complex program to make the conveying mechanism and the die-cutting knife cooperate precisely, but also increases the production cost.

[0008] Therefore, how to avoid wrinkles on PC film on a die-cutting device while improving die-cutting efficiency is an urgent problem to be solved. Summary of the invention

[0009] The object of the present invention is to provide a die-cutting device for a conductive film to solve the problems raised in the above background technology.

[0010] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a die-cutting device for conductive film, comprising a frame and a conveying frame installed on the frame, a die-cutting station is provided on the frame, a PC film is installed on the frame, the PC film passes through the die-cutting station, a die-cutting piece for die-cutting operation is slidably connected to the frame, and a driving unit for driving the die-cutting piece to slide vertically is provided on the frame, a pressure mechanism is provided on the frame, and the pressure mechanism and the die-cutting piece are connected by a transmission member so that the pressure mechanism intermittently contacts the PC film; a conveying member for conveying the PC film is provided inside the conveying frame; when the die-cutting operation is completed, the driving unit drives the die-cutting piece to slide upward, and the pressure mechanism is driven to contact the PC film by the transmission member, and then the conveying member is driven by the intermittent linkage member to convey the PC film.

[0011] Furthermore, the frame is vertically slidably connected with multiple groups of driving rods fixedly connected to the cutting parts, and the two driving rods located on the same side of the frame are fixedly connected through a fixed plate; the transmission part includes a rotating rod rotatably connected to the frame, the rotating rod is provided with a driving gear, and the fixed plate is fixedly connected with a driving rack, and the driving rack is meshed with the driving gear.

[0012] Furthermore, the pressure mechanism includes a supporting block slidably connected to the frame, a connecting frame is installed on the supporting block, and multiple groups of pressure rollers are rotatably connected to the connecting frame; a transmission rack is arranged on the bottom of the supporting block, and a transmission gear meshing with the transmission rack is arranged on the rotating rod.

[0013] Furthermore, the conveying member includes a first conveying roller and a second conveying roller rotatably connected to the conveying frame, and the first conveying roller and the second conveying roller are both provided with spur gears, and the two spur gears are meshed.

[0014] Furthermore, the intermittent connecting member includes a supporting tube, which is fixedly connected to the second conveying roller; a linkage rod is installed in the supporting tube, and a plurality of groups of bases are fixedly connected to the linkage rod, and each base is rotatably connected to a ratchet; a tooth groove is opened on the inner side of the supporting tube, and a torque spring is arranged between each ratchet and the corresponding base, and the elastic force of the torque spring drives the corresponding ratchet to engage in the tooth groove.

[0015] Furthermore, the rotating rod and the linkage rod are connected to each other through a transmission unit; the transmission unit includes a first gear mounted on the rotating rod, a second gear is mounted on the linkage rod, and the first gear is meshed with the second gear.

[0016] Furthermore, the frame is provided with a cleaning piece for cleaning the PC film, and the frame is provided with a driving portion for driving the cleaning piece to slide downward until it contacts the PC film; when the driving unit drives the die-cutting piece to slide upward, the driving portion is also driven by the transmission member to apply pressure to the cleaning piece, and the PC film is cleaned by the cleaning piece.

[0017] Furthermore, the cleaning member comprises a mounting plate, a cleaning plate is arranged at the bottom of the mounting plate; and the mounting plate is slidably connected to the frame via an elastic positioning member.

[0018] Furthermore, the driving part includes a driving frame fixedly connected to the rotating rod, and the mounting plate begins to have an adapting groove adapted to the driving frame. When the rotating rod rotates, the driving frame rotates into the adapting groove, and drives the mounting plate to drive the cleaning plate to slide downward through the adapting groove to clean the PC film.

[0019] Furthermore, a power box is arranged on the bottom of the frame, and the driving unit is installed in the power box.

[0020] Compared with the prior art, the present invention has the following beneficial effects: The die-cutting equipment for conductive film is coordinated between a frame, a die-cutting machine, a driving unit, a pressure mechanism, a transmission member, and an intermittent linkage member. Specifically, in actual use, the PC film is mounted on the frame. At this moment, the driving unit drives the die-cutting member to slide downward. After the die-cutting member slides downward to the die-cutting station, the PC film is die-cut. During the downward sliding stroke of the die-cutting member, the transmission member drives the pressure mechanism away from the PC film, thereby avoiding motion interference between the die-cutting member and the pressure mechanism, and thus avoiding affecting the die-cutting operation. After the die-cutting operation is completed, when the driving unit drives the die-cutting member to slide upward, the transmission member drives the pressure mechanism to slide toward one side of the PC film, and the pressure mechanism fixes the PC film. Obviously, when the die-cutting member is separated from the PC film, the PC film is restricted by the pressure mechanism at this moment, so the PC film does not slide upward together with the die-cutting member, avoiding wrinkles on the PC film, improving the die-cutting quality, and achieving better use effect.

[0021] At the same time, when the driving unit drives the die-cutting part to slide upward, it will also drive the conveying part to convey the PC film through the intermittent connecting part. The conveying part will slide the PC film after the die-cutting operation upward for a certain distance, so as to facilitate the next time the driving unit drives the die-cutting part to slide downward and perform the die-cutting operation on the PC film again. Therefore, there is no need to set up a separate conveying device to convey the PC film, and there is no need to set up a complicated operating procedure. The conveying device and the die-cutting part cooperate, which improves work efficiency and can greatly save costs.

[0022] Furthermore, by setting the coordination between the cleaning member, the driving part, etc., the contact between the cleaning member and the PC film can be passively achieved through the driving part, without the need to separately set a driving source to drive the cleaning member to slide. Specifically, the conveying member is driven to operate through the linkage member, and the PC film is driven to slide through the conveying member. At this moment, the cleaning member abuts against the PC film, thereby passively increasing the friction between the cleaning member and the PC film, thereby achieving a PC film cleaning effect and improving the PC film cleaning efficiency. Therefore, the PC film can achieve a cleaning effect, further improving the practicality of the die-cutting equipment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-14 The present invention provides a technical solution: a die-cutting device for conductive film, comprising a frame 1 and a conveying frame 2 installed on the frame 1, a die-cutting station is provided on the frame 1, a PC film 3 is installed on the frame 1, the PC film 3 passes through the die-cutting station, a die-cutting piece 4 for die-cutting operation is slidably connected to the frame 1, and a driving unit for driving the die-cutting piece 4 to slide vertically is provided on the frame 1, a pressure mechanism 9 is provided on the frame 1, and the pressure mechanism 9 and the die-cutting piece 4 are connected by a transmission member so that the pressure mechanism 9 intermittently contacts the PC film 3; a conveying member 15 for conveying the PC film 3 is provided inside the conveying frame 2; when the die-cutting operation is completed, the driving unit drives the die-cutting piece 4 to slide upward, and the pressure mechanism 9 is driven to contact the PC film 3 by the transmission member, and then the conveying member 15 is driven by the intermittent linkage member 17 to convey the PC film 3.

[0028] Specifically, the die-cutting equipment for the conductive film includes a frame 1 and a conveyor frame 2 installed on the frame 1. A plurality of support rods are fixedly connected to the bottom of the frame 1, and a non-slip pad is provided on the bottom of each support rod, so as to improve the stability of the entire die-cutting equipment during operation and meet the working needs. A die-cutting station is provided on the frame 1, and a PC film 3 is installed on the frame 1. The PC film 3 runs through the die-cutting station to facilitate the die-cutting operation. A die-cutting piece 4 for die-cutting operation is slidably connected to the frame 1. Specifically, the die-cutting piece 4 includes a supporting plate, and a die-cutting knife is provided on the bottom of the supporting plate. The die-cutting piece 4 is a prior art and can perform die-cutting operations on the PC film 3. Its detailed structure and working principle are not described here.

[0029] The frame 1 is provided with a driving unit for driving the die-cutting piece 4 to slide vertically, which is convenient for driving the die-cutting piece 4 to slide vertically to meet the working needs. Specifically, the driving unit is a servo cylinder 10, which is convenient for providing power to the die-cutting piece 4 so that the die-cutting piece 4 can slide back and forth on the frame 1. A pressure mechanism 9 is provided on the frame 1. Specifically, there can be multiple groups of pressure mechanisms 9, and they are symmetrically arranged on both sides of the frame 1, so as to further improve the stability of the PC film 3 during installation. Multiple groups of carrying boxes 8 are fixedly connected on both sides of the frame 1, and each pressure mechanism 9 is slidably connected to the frame 1 through the carrying box 8. The pressure mechanism 9 is connected to the die-cutting piece 4 through a transmission member, so that the pressure mechanism 9 intermittently abuts against the PC film 3. That is, when the driving unit drives the die-cutting piece 4 to slide downward, the pressure-applying mechanism 9 is caused to slide away from the PC film 3 through the transmission member, so as to avoid affecting the die-cutting operation; when the die-cutting operation is completed, when the driving unit drives the die-cutting piece 4 to slide upward, the pressure-applying mechanism 9 is driven to slide toward the PC film 3 through the transmission member, and the PC film 3 is fixed by the pressure-applying mechanism 9. Obviously, when the die-cutting piece 4 is separated from the PC film 3, the PC film 3 is restricted by the pressure-applying mechanism 9 at this moment, so that the PC film 3 will not slide upward together with the die-cutting piece 4, thereby avoiding the occurrence of wrinkles in the PC film 3, thereby improving the die-cutting quality of the entire PC film 3 and meeting work needs.

[0030] Specifically, the pressure mechanism 9 and the conveying frame 2 are internally provided with a conveying member 15 for conveying the PC film 3. After the die-cutting operation is completed, the conveying member 15 slides the PC film 3 after the die-cutting operation upward for a certain distance, so as to facilitate the next driving unit to drive the die-cutting member 4 to slide downward and perform the die-cutting operation on the PC film 3 again. Therefore, there is no need to set up a separate conveying device to convey the PC film 3, and there is no need to set up a complicated operating procedure. The conveying device cooperates with the die-cutting member 4, which improves work efficiency and can greatly save costs, and is suitable for wide promotion and use.

[0031] Therefore, when the die-cutting operation is completed, the driving unit drives the die-cutting member 4 to slide upwards, and then drives the pressure mechanism 9 to contact the PC film 3 through the transmission member, and then drives the conveying member 15 to convey the PC film 3 through the intermittent linkage member 17. By setting the intermittent linkage member 17, it can be ensured that when the driving unit drives the die-cutting member 4 to slide downwards, the intermittent linkage member 17 will not drive the conveying member 15 to rotate, and the PC film 3 at this moment is in a static state, so as to avoid affecting the die-cutting operation of the PC film 3. Only when the die-cutting operation is completed, when the driving unit drives the die-cutting member 4 to slide upwards, can the PC film 3 be driven to slide forward for a certain distance, so as to facilitate the next time the driving unit drives the die-cutting member 4 to slide downwards and perform the die-cutting operation on the PC film 3 again.

[0032] Specifically, during actual use, the PC film 3 is mounted on the frame 1. At this moment, the die-cutting piece 4 is driven to slide downward by the driving unit. After the die-cutting piece 4 slides downward to the die-cutting station, the PC film 3 is die-cut. During the downward sliding stroke of the die-cutting piece 4, the pressure mechanism 9 is driven away from the PC film 3 by the transmission member, thereby avoiding motion interference between the die-cutting piece 4 and the pressure mechanism 9, and thus avoiding affecting the die-cutting operation. After the die-cutting operation is completed, when the driving unit drives the die-cutting piece 4 to slide upward, the pressure mechanism 9 is driven to slide toward one side of the PC film 3 by the transmission member, and the PC film 3 is fixed by the pressure mechanism 9. Obviously, when the die-cutting piece 4 is separated from the PC film 3, the PC film 3 is restricted by the pressure mechanism 9 at this moment, so the PC film 3 will not slide upward together with the die-cutting piece 4, avoiding wrinkles on the PC film 3 and improving the die-cutting quality. At the same time, when the driving unit drives the die-cutting piece 4 to slide upward, it will also drive the conveying piece 15 to convey the PC film 3 through the intermittent connecting piece. The conveying piece 15 will slide the PC film 3 after the die-cutting operation upward for a certain distance, so as to facilitate the next time the driving unit drives the die-cutting piece 4 to slide downward and perform the die-cutting operation on the PC film 3 again. Therefore, there is no need to set up a separate conveying device to convey the PC film 3, and there is no need to set up a complicated operating procedure. The conveying device cooperates with the die-cutting piece 4, which improves work efficiency and can greatly save costs.

[0033] In the embodiment provided by the present invention, there are multiple groups of driving rods 6 fixedly connected to the die-cutting piece and connected vertically and slidably on the frame 1. There are multiple groups of through holes on the frame 1, and each driving rod 6 is slidably connected to the frame 1 through the through holes. The two driving rods 6 on the same side of the frame 1 are fixedly connected by a fixed plate, and when the fixed plate slides, the multiple groups of driving rods 6 are driven to slide vertically synchronously. The transmission member includes a rotating rod 7 rotatably connected to the frame 1, and specifically, the rotating rod 7 is rotatably connected to the carrying box 8. A driving gear 12 is provided on the rotating rod 7, and a driving rack 11 is fixedly connected to the fixed plate, and the driving rack 11 is meshed with the driving gear 12. Specifically, a connecting plate is provided on the output end of the servo cylinder 10, and the connecting plate is fixedly connected to the fixed plates on both sides. Therefore, during use, the driving rods 6 on both sides are driven to slide vertically through the cooperation between the servo cylinder 10 and the fixed plate, thereby driving the die-cutting piece 4 to slide vertically. At the same time, when the driving rod 6 slides vertically, it will drive the rack 11 to slide vertically, so that the driving rack 11 drives the driving gear 12 to rotate, thereby providing power for the rotation of the rotating rod 7, which is convenient for subsequent operations.

[0034] In the embodiment provided by the present invention, the pressure mechanism 9 includes a bearing block 9.1 slidably connected to the frame 1, a connecting frame 9.2 is installed on the bearing block 9.1, and a plurality of pressure rollers 9.3 are rotatably connected to the connecting frame 9.2; a transmission rack 14 is arranged on the bottom of the bearing block 9.1, and a transmission gear 13 meshing with the transmission rack 14 is arranged on the rotating rod 7. Therefore, during use, when the rotating rod 7 rotates, the transmission gear 13 is driven to rotate, and the transmission gear 13 drives the transmission rack 14 to slide, thereby driving the bearing block 9.1 to slide horizontally, so that the state of the pressure mechanism 9 can be adjusted. Specifically, the connecting frame 9.2 and the bearing block 9.1 are slidably connected, a plurality of sets of vertical rods 9.4 are fixedly connected to the connecting frame 9.2, a plurality of sets of vertical grooves are opened on the bearing block 9.1, the vertical rods 9.4 are vertically slidably connected in the vertical grooves, and a guide rod 9.5 is fixedly connected to the side wall of the connecting frame 9.2, a guide groove 9.6 is opened on the inner wall of the bearing block, and the guide groove 9.6 is in an inclined state. After the die-cutting operation is completed, when the driving unit drives the die-cutting piece 4 to slide upward, it will drive the rack 11 to slide vertically through the driving rod 6, so that the driving rack 11 drives the driving gear 12 to rotate, and then can drive the rotating rod 7 to rotate. During the rotation of the rotating rod 7, the transmission gear 13 will be driven to rotate, and the transmission rack 14 will be driven to slide through the transmission gear 13, and then the supporting block 9.1 can be driven to slide horizontally toward the side close to the PC film 3. During the sliding stroke of the supporting block 9.1, the supporting frame is driven to slide through the vertical rod 9.4. At this moment, the guide rod 9.5 slides inside the guide groove 9.6, so that the supporting frame drives the pressure roller 9.3 to contact the PC film 3, restrict the PC film 3, and meet the working needs.

[0035] In the embodiment provided by the present invention, the conveying member 15 includes a first conveying roller 15.1 and a second conveying roller 15.2 which are rotatably connected to the conveying frame 2. The first conveying roller 15.1 and the second conveying roller 15.2 are both provided with a spur gear 15.3, and the two spur gears 15.3 are meshed. Specifically, the PC film 3 passes between the first conveying roller 15.1 and the second conveying roller 15.2, and abuts against the first conveying roller 15.1 and the second conveying roller 15.2. Therefore, when working, the two spur gears 15.3 are meshed, which will drive the first conveying roller 15.1 and the second conveying roller 15.2 to rotate. Due to the restriction of the two spur gears 15.3, the rotation directions of the first conveying roller 15.1 and the second conveying roller 15.2 are opposite, and the friction between the first conveying roller 15.1 and the second conveying roller 15.2 and the PC film 3 is utilized, so that the PC film 3 transmission operation can be realized. At the same time, the friction between the first conveying roller 15.1 and the second conveying roller 15.2 and the PC film 3 is greater than the friction between the pressure roller 9.3 and the PC film 3. Therefore, when the first conveying roller 15.1 and the second conveying roller 15.2 rotate, the transmission operation of the conductive film can be easily achieved to meet the working needs.

[0036] In the embodiment provided by the present invention, specifically, the intermittent connection member includes a bearing cylinder 17.1, and the bearing cylinder 17.1 is fixedly connected to the second conveying roller 15.2, so when the bearing cylinder 17.1 rotates, it will drive the second conveying roller 15.2 to rotate, and drive the first conveying roller 15.1 to rotate through the cooperation of the spur gear 15.3. A linkage rod 17.2 is installed in the bearing cylinder 17.1, and a plurality of groups of bases 17.5 are fixedly connected to the linkage rod 17.2, and each base 17.5 is rotatably connected to a ratchet 17.4; a tooth groove 17.3 is opened on the inner side of the bearing cylinder 17.1, and a torque spring is arranged between each ratchet 17.4 and the corresponding base 17.5, and the elastic force of the torque spring drives the corresponding ratchet 17.4 to be clamped in the tooth groove 17.3. The rotating rod 7 and the linkage rod 17.2 are connected to each other through the transmission unit 16; the transmission unit 16 includes a first gear mounted on the rotating rod 7, and a second gear mounted on the linkage rod 17.2, and the first gear meshes with the second gear. During the working process, when the die-cutting operation is completed, the driving unit drives the die-cutting piece 4 to slide upward, and drives the rotating rod 7 to rotate through the transmission member. When the rotating rod 7 rotates, the linkage rod 17.2 is driven to rotate through the cooperation of the first gear and the second gear. At this moment, refer to Fig. 9, the linkage rod 17.2 rotates clockwise. When the linkage rod 17.2 rotates, the end of the ratchet 17.4 is clamped in the tooth groove 17.3, that is, when the linkage rod 17.2 rotates, the ratchet 17.4 is driven to rotate, and the cooperation between the ratchet 17.4 and the tooth groove 17.3 drives the carrier tube 17.1 to rotate. When the carrier tube 17.1 rotates, it drives the second conveying roller 15.2 to rotate, and the cooperation of the spur gear 15.3 drives the first conveying roller 15.1 to rotate. The rotation directions of the first conveying roller 15.1 and the second conveying roller 15.2 are opposite. The friction between the first conveying roller 15.1 and the second conveying roller 15.2 and the PC film 3 can realize the transmission operation of the PC film 3. When the die-cutting operation is performed, at this moment, when the driving unit drives the die-cutting part 4 to slide downward, the rotating rod 7 is driven to rotate through the transmission member. When the rotating rod 7 rotates, the linkage rod 17.2 is driven to rotate in the opposite direction through the cooperation of the first gear and the second gear. At this moment, refer to Fig.10 , the linkage rod 17.2 rotates counterclockwise, and the tooth back of the ratchet 17.4 contacts the tooth groove 17.3 at this time, so the ratchet 17.4 cannot drive the second conveying roller 15.2 to rotate through the bearing tube 17.1, so the intermittent linkage member 17 does not drive the conveying member 15 to rotate, and the PC film 3 is in a static state at this moment, avoiding affecting the die-cutting operation of the PC film 3. On the contrary, only after the die-cutting operation is completed, when the driving unit drives the die-cutting member 4 to slide upward, can the PC film 3 be driven to slide forward for a certain distance, so as to facilitate the next time the driving unit drives the die-cutting member 4 to slide downward, and the PC film 3 is die-cut again, and the cycle is repeated, which is convenient for the operation of the entire die-cutting equipment.

[0037] In the embodiment provided by the present invention, a cleaning member 18 for cleaning the PC film 3 is provided on the frame 1. Therefore, during use, the cleaning member 18 is used to clean the dust and impurities on the PC film 3, thereby reflecting the versatility of the die-cutting device and achieving a better use effect. At the same time, a driving unit 19 is provided on the frame 1 for driving the cleaning member 18 to slide downward until it contacts the PC film 3. Therefore, during use, the contact between the cleaning member 18 and the PC film 3 can be passively achieved through the driving unit 19, and there is no need to separately set a driving source to drive the cleaning member 18 to slide, thereby achieving a better use effect. More specifically, when the driving unit drives the die-cutting member 4 to slide upward, the driving unit 19 is also driven by the transmission member to apply pressure to the cleaning member 18, and the PC film 3 is cleaned by the cleaning member 18. Specifically, from the above records, when the die-cutting operation is completed, the driving unit drives the die-cutting piece 4 to slide upward, and the intermittent linkage piece 17 drives the second conveying roller 15.2 to rotate, and the friction between the first conveying roller 15.1 and the second conveying roller 15.2 and the PC film 3 is used to realize the transmission operation of the PC film 3. When the PC film 3 slides, the cleaning piece 18 at this moment abuts against the PC film 3, so that the friction between the cleaning piece 18 and the PC film 3 body can be passively increased, so that the PC film 3 can achieve a cleaning effect, greatly improving the practicality of the die-cutting equipment and meeting work needs. More specifically, the friction between the first conveying roller 15.1 and the second conveying roller 15.2 when rotating is greater than the friction between the cleaning piece 18 and the PC film 3, so it does not affect the normal transportation of the PC film 3.

[0038] In the embodiment provided by the present invention, specifically, the cleaning member 18 includes a mounting plate 18.1, and a cleaning plate 18.2 is arranged at the bottom of the mounting plate 18.1; and the mounting plate 18.1 is slidably connected to the frame 1 through an elastic positioning member. The positioning member includes a limit rod 18.3 fixedly connected to the bottom of the mounting plate 18.1, and a limit slot is provided on the frame 1, wherein the limit rod 18.3 is slidably connected in the limit slot, and a positioning spring 18.4 is arranged between the limit rod 18.3 and the limit slot, and the elastic force of the positioning spring 18.4 drives the cleaning plate 18.2 away from the PC film 3, so when the driving part 19 is not in contact with the mounting plate 18.1, the positioning spring 18.4 drives the mounting plate 18.1 to slide upward in the process of restoring the elastic deformation, so that it is convenient to drive the mounting plate 18.1 to slide downward by the driving part 19 next time, so as to meet the working needs.

[0039] In the embodiment provided by the present invention, the driving part 19 includes a driving frame 19.1 fixedly connected to the rotating rod 7, and the mounting plate 18.1 begins to have an adapting groove 19.2 adapted to the driving frame 19.1. When the rotating rod 7 rotates, the driving frame 19.1 rotates into the adapting groove 19.2, and the mounting plate 18.1 drives the cleaning plate 18.2 to slide downward through the adapting groove 19.2 to clean the PC film 3. Therefore, during use, when the rotating rod 7 rotates, the driving frame 19.1 drives the mounting plate 18.1 to slide downward through the cooperation with the adapting groove 19.2, and the cleaning plate 18.2 abuts against the PC film 3. When the PC film 3 slides, the cleaning member 18 at this moment abuts against the PC film 3, thereby passively increasing the friction between the cleaning member 18 and the PC film 3 body, improving the cleaning efficiency of the PC film 3, so that the PC film 3 can achieve a cleaning effect and meet the work needs.

[0040] In the embodiment provided by the present invention, a power box 5 is provided on the bottom of the frame 1 , and the driving unit is installed in the power box 5 , so as to facilitate the installation and use of the servo cylinder 10 .
