Description

Technical Field

[0001] This utility model relates to the field of film production technology, and in particular to a slitting device for plastic film production. Background Technology

[0002] In film production, the formed film needs to be wound up and packaged by a winding device. Therefore, a slitting device for plastic film production, with publication number CN216302844U, first clamps the top of the film by the end feeding clamp, and the feeding claw group clamps the two sides of the film. Then, the lifting linkage descends, driving the top roller mounting frame on the active pressure roller synchronously to descend synchronously with the active pressure roller mounting frame, pressing the film between the active roller and the passive pressure roller, thus achieving tensioning of the film. Then, the winding main roller starts to rotate, driving the film to start the winding operation.

[0003] After the film is wound to a certain length, it needs to be cut and a new take-up roller needs to be replaced. After the film is cut, it needs to be pulled again so that it passes through the feeding mechanism and is clamped again in the end feeding fixture. This process requires manual operation and may take some time. Utility Model Content

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] like Figures 1-4 As shown, a slitting device for plastic film production includes a frame 1. From left to right, a winding mechanism, a tension adjustment mechanism, and a traction mechanism are sequentially arranged on the frame 1. The winding mechanism is used to wind the plastic film, the tension adjustment mechanism is used to adjust the tightness of the plastic film, and the traction mechanism is used to pull the cut plastic film through the tension adjustment mechanism to the winding mechanism for winding.

[0024] The tension adjustment mechanism includes several fixed frames 2, which are arranged equidistantly and have tension rollers 4 rotatably connected to their top edges. The fixed frames 2 are arranged side-by-side between the winding mechanism and the traction mechanism. The tension adjustment mechanism also includes a lifting frame 3, which is located above the fixed frames 2 and has several tension rollers 4 rotatably connected to its bottom. Vertically distributed electric push rods 5 are arranged between the top edge of the lifting frame 3 and the frame 1. Several winding rollers 8 on the tension adjustment mechanism are arranged parallel to the anti-slip rollers 14, and several tension rollers on the lifting frame 3... The tension rollers 4 on the lifting frame 3 and the fixed frame 2 are staggered and distributed. The tension rollers 4 on the fixed frame 2 are set lower than the rotating frame 7. When the plastic film passes between the lifting frame 3 and the fixed frame 2, the lifting frame 3 is lowered by the retraction of the electric push rod 5. This allows the tension rollers 4 on the lifting frame 3 to press the surface of the plastic film. As the lifting frame 3 continues to descend, until the tension rollers 4 on the lifting frame 3 and the tension rollers 4 on the fixed frame 2 are staggered, the originally horizontal plastic film becomes a zigzag shape, and the tightness of the plastic film can be adjusted.

[0025] The winding mechanism includes outer supports 6 on both sides of the fixed mounting frame 1 and located outside the two linear modules 12. A rotating frame 7 is rotatably connected to the top edge of the opposite face of the two outer supports 6. Two winding rollers 8 are mounted on the rotating frame 7. The two winding rollers 8 are used alternately. The winding roller 8 in the lower position is used to wrap the plastic film. After wrapping, the rotating frame 7 rotates 180 degrees to swap the positions of the upper and lower winding rollers 8. The empty winding roller 8 that was originally located at the top can then be used to continue wrapping the plastic film, while the winding roller 8 that has been wrapped moves to the upper position. For easy removal and replacement of the take-up roller 8, the rotating frame 7 is equipped with arc-shaped clamping blocks 20 for clamping the ends of the take-up roller 8 via bolts 18. These arc-shaped clamping blocks 20 hold the ends of the central shafts extending from both ends of the take-up roller 8, ensuring that the rotation of the take-up roller 8 is not affected and that its position can be interchanged as the rotating frame 7 rotates. Flanges 21 are rotatably connected to both take-up rollers 8 on the same side of the rotating frame 7. A motor 17 for driving the rotation of the flanges 21 is fixedly mounted on the rotating frame 7. The flanges 21 are connected to the take-up rollers... One end of the roller 8 is connected by bolts 18. Using bolts 18 to connect the flange 21 to the already fixed end of the take-up roller 8, the flange 21 can be rotated by the motor 17 to achieve the rotation of the take-up roller 8 to wind the plastic film. The take-up mechanism also includes a pneumatic telescopic rod 9 fixedly installed above the frame 1 and between the two outer supports 6. A magnetic strip 11 is fixedly installed at the telescopic end of the pneumatic telescopic rod 9. A locking strip 10 is magnetically attracted to the magnetic strip 11. A slot 19 for inserting into the locking strip 10 is provided on the surface of the take-up roller 8. When installing the take-up roller 8, the take-up... The slot 19 on roller 8 faces away from the central axis of the rotating frame 7. Therefore, the slot 19 on the surface of the lower take-up roller 8 faces downward. When the traction mechanism pulls one end of the plastic film to the area below the lower take-up roller 8, the pneumatic telescopic rod 9 extends to make the magnetic strip 11 drive the clip 10 to rise. The rising clip 10 presses down on the plastic film and then moves into the slot 19, thus fixing one end of the plastic film to the take-up roller 8. Then, the pneumatic telescopic rod 9 retracts to make the magnetic strip 11 descend, and the take-up roller 8 rotates and winds the plastic film.

[0026] The traction mechanism's movement path passes through the tension adjustment mechanism and the winding mechanism. The traction mechanism includes two linear modules 12 fixed to both sides of the frame 1 and passing through the winding mechanism and the tension adjustment mechanism. The slides of the two linear modules 12 extend upwards and are equipped with rotating seats 13. By simultaneously pneumatically maneuvering the two linear modules 12, the two rotating seats 13 can move at the same speed and in the same direction. A disassembly / assembly frame 15 is provided above the rotating seat 13, and anti-slip rollers 14 are fixedly installed on the opposite surfaces of the rotating seat 13 and the disassembly / assembly frame 15. Electric telescopic rods 16 are fixedly installed through the bottom of the rotating seat 13 at both ends of the anti-slip rollers 14. The telescopic ends of the electric telescopic rods 16 face upwards and are fixedly installed with bolts 18. The bottom sides of the disassembly / assembly frame 15 are U-shaped and overlap with the two bolts 18 respectively. The nuts of the bolts 18 overlap with the upper surface of the disassembly / assembly frame 15. Figure 2 As shown, the two ends of the disassembly frame 15 are secured to bolts 18 on the telescopic ends of the two electric telescopic rods 16, and the nuts on the bolts 18 press the upper surface of the disassembly frame 15. Then, the disassembly frame 15 can be lowered by retracting the two electric telescopic rods 16, which allows the two anti-slip rollers 14 to move relative to each other and clamp the plastic film. The linear module 12 can then drive the rotating seat 13 and the disassembly frame 15 to move towards the winding mechanism after passing through the tension adjustment mechanism. After the plastic film is tractioned, in order to facilitate the reset of the traction mechanism, a motor 17 is embedded and fixedly installed in the slide extension of one of the linear modules 12. The main shaft of motor 17 faces upward and is fixedly connected to one end of the bottom edge of rotating frame 7. The top edge of the slide extension of another linear module 12 is connected to the other end of the bottom edge of rotating frame 7 by a pin. By rotating and removing the nut on bolt 18, the disassembly frame 15 can be removed. Then, by pulling out the pin connecting rotating frame 7 and the slide of another linear module 12, the motor 17 can drive rotating frame 7 to rotate, so that rotating frame 7 is misaligned with winding mechanism and tension adjustment mechanism. That is, after rotating frame 7 rotates 90 degrees, it is parallel to the long side of belt conveyor, which makes it easy for disassembly frame 15 to be reset with the operation of linear module 12.

[0027] The method of using this utility model is as follows: After the plastic film is wound on the lower take-up roller 8, the two electric telescopic rods 16 retract, causing the disassembly frame 15 to descend. This allows the two anti-slip rollers 14 to move relative to each other and clamp the plastic film. Then, the lifting frame 3 in the tension adjustment mechanism rises and cuts the plastic film. The rotating frame 7 rotates, causing the upper empty take-up roller 8 to move to the lower position. The linear module 12 drives the rotating seat 13 and the disassembly frame 15 to move the plastic film towards the take-up mechanism after passing through the tension adjustment mechanism. After the plastic film is pulled, the pneumatic telescopic rod 9 extends, causing the magnetic strip 11 to drive the clamping strip 10 to rise. The rising clamping strip 10 presses against the plastic film and then clamps it into place. Inside the groove 19, one end of the plastic film can be fixed to the take-up roller 8. Then, the electric telescopic rod 16 extends to release the clamping of the anti-slip roller 14 on the plastic film. Then, the pneumatic telescopic rod 9 retracts to lower the magnetic strip 11, allowing the plastic film to be wound around the take-up roller 8. Rotate to remove the nut on the bolt 18 to remove the disassembly frame 15. Then, by pulling out the pin connecting the rotating frame 7 to the slide of another linear module 12, the motor 17 can drive the rotating frame 7 to rotate, achieving misalignment between the rotating frame 7 and the take-up mechanism and the tension adjustment mechanism. That is, after the rotating frame 7 rotates 90 degrees, it is parallel to the long side of the belt conveyor, which facilitates the reset of the disassembly frame 15 as the linear module 12 rotates, making it convenient for the next traction of the plastic film.

[0028] The wiring diagrams of the electric push rod 5, pneumatic telescopic rod 9, linear module 12, electric telescopic rod 16, and motor 17 in this utility model are common knowledge in the field, and their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring layouts of the electric push rod 5, pneumatic telescopic rod 9, linear module 12, electric telescopic rod 16, and motor 17 will not be explained in detail.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
