Description

Technical Field

[0001] The utility model relates to the technical field of static electricity films, in particular to a slitting device for producing PE static electricity films. Background Technique

[0002] The static electricity film is a non-coated film, mainly made of PE and PVC materials. It adheres to objects by the static electricity adsorption of the product itself to play a protective role. Generally, it is used for surfaces that are more sensitive to the residue of adhesives or glue, and is mostly used for very smooth surfaces such as glass, lenses, high-gloss plastic surfaces, and acrylic. There is no static electricity felt on the outside of the static electricity film. It is a self-adhesive film with low adhesion. It is sufficient for use on high-brightness surfaces. Generally, the thicknesses are 3 filaments, 5 filaments, and 8 filaments, and the color is transparent.

[0003] After retrieval, in a PE film cutting machine with the patent publication number CN218226917U, it is proposed that "in this PE film cutting machine, when cutting the PE film, if the film body is loose during the cutting process, it will cause the finished product to not meet the standards, resulting in waste. Therefore, before cutting, the material roller is adjusted up and down by the first electric telescopic rod, so that the film body passing through the driving roller is tightened, thus completing the adjustment of the tightness. At the same time, when moving the material roller up and down, the limiting rod is used to prevent it from shaking, so that it can be stably adjusted";

[0004] However, there are still certain deficiencies in the above scheme during actual use. There is no positioning measure during the conveying process before cutting in this scheme, which easily leads to deviation in the position of the static electricity film before cutting, resulting in loose wrinkles and unevenness when the static electricity film is cut, making the device unable to accurately cut the static electricity film, and further causing the problem of reducing the cutting accuracy. Content of the Utility Model

[0005] The utility model provides a slitting device for producing PE static electricity films to solve the problems in the background technique.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: A slitting device for producing PE static electricity films includes a processing table. At the top of the processing table, there are arranged a material roller structure, a guiding structure, a conveying structure, a cutting mechanism, and a storage roller. The arrangement order of the material roller structure, the guiding structure, the conveying structure, the cutting mechanism, and the storage roller is arranged in sequence from front to back. A material receiving groove is opened behind the storage roller;

[0007] The guiding structure includes a driving box. The outside of the driving box is connected to the processing table through a mounting frame. The inner wall of the driving box is rotationally connected with a double-screw rod through a built-in motor. The surface of the double-screw rod is threadedly connected with two threaded blocks. The bottom end of the threaded block is fixedly installed with a fixed collar, and the bottom end of the fixed collar is provided with a movable collar;

[0008] The inner wall of the mounting frame is rotatably connected with a fixed guiding roller and a movable guiding roller, and the fixed collar and the movable collar are respectively lapped on the surfaces of the fixed guiding roller and the movable guiding roller.

[0009] Further, a slide rail is fixedly installed at the bottom end of the fixed collar, and a plug rod is slidably connected to the inner wall of the slide rail. The bottom end of the plug rod is fixedly connected to the top end of the movable collar.

[0010] Further, a chute is formed in the inner wall of the mounting frame. One end of the movable guiding roller is slidably connected to the inner wall of the chute, and the other end of the movable guiding roller faces the opening of the limiting hole formed inside the mounting frame.

[0011] Further, a limiting pin is movably inserted into the limiting hole, and the limiting pin is lapped on one end of the movable guiding roller at the same height as the limiting hole.

[0012] Further, the cutting mechanism includes a driving frame, a cutting knife is arranged inside the driving frame, and a waste material groove is arranged below the driving frame.

[0013] Compared with the prior art, the utility model provides a slitting device for PE electrostatic film production, and has the following beneficial effects:

Specific implementation manner

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-5 , the present invention discloses a slitting device for PE electrostatic film production, including a processing table 1. A material roller structure 2, a guiding structure 3, a conveying structure 4, a cutting mechanism 5 and a storage roller 6 are arranged on the top end of the processing table 1. The arrangement order of the material roller structure 2, the guiding structure 3, the conveying structure 4, the cutting mechanism 5 and the storage roller 6 is arranged in sequence from front to back. A material receiving chute 7 is opened behind the storage roller 6.

[0023] The cutting mechanism 5 includes a driving frame 501. A cutting knife 502 is arranged inside the driving frame 501. A waste chute 503 is arranged below the driving frame 501.

[0024] The guiding structure 3 includes a driving box 301. The outside of the driving box 301 is connected to the processing table 1 through a mounting frame 302. A double-shaft screw 303 is rotatably connected to the inner wall of the driving box 301 through a built-in motor. Two threaded blocks 304 are threadedly connected to the surface of the double-shaft screw 303. A fixed collar 305 is fixedly installed at the bottom end of the threaded block 304. A movable collar 308 is arranged at the bottom end of the fixed collar 305;

[0025] A fixed guiding roller 309 and a movable guiding roller 311 are rotatably connected to the inner wall of the mounting frame 302. The fixed collar 305 and the movable collar 308 are respectively lapped on the surfaces of the fixed guiding roller 309 and the movable guiding roller 311.

[0026] By setting the guiding structure 3, the high end of the driving box 301 can be used to lap the built-in motor, and the two threaded blocks 304 can be driven by the double-shaft screw 303 to drive the fixed collar 305 and the movable collar 308 to move towards each other, so that the intervals between the two fixed collars 305 and the movable collar 308 can be adjusted according to the width of the electrostatic film, prompting the two groups of fixed collars 305 and the movable ones to perform adaptive limiting on the electrostatic film, enabling the electrostatic film to be positioned, avoiding the situation that the electrostatic film is prone to position deviation before cutting, and preventing the electrostatic film from being loose, wrinkled and uneven during cutting, so that the device can accurately cut the electrostatic film.

[0027] Specifically, a slide rail 306 is fixedly installed at the bottom end of the fixed collar 305, and a plug rod 307 is slidably connected to the inner wall of the slide rail 306. The bottom end of the plug rod 307 is fixedly connected to the top end of the movable collar 308.

[0028] In this embodiment, by the mutual cooperation of the slide rail 306 and the plug rod 307, the interval between the fixed collar 305 and the movable collar 308 can be adjusted more smoothly.

[0029] Specifically, a chute 310 is opened on the inner wall of the mounting frame 302. One end of the movable guide roller 311 is slidably connected to the inner wall of the chute 310. The other end of the movable guide roller 311 faces the opening of the limit hole 312 opened inside the mounting frame 302. A limit pin 313 is movably inserted into the limit hole 312, and the limit pin 313 is lapped with the end of the movable guide roller 311 that is at the same height as the limit hole 312.

[0030] In this embodiment, the chute 310 enables the movable guide roller 311 to perform lifting movement, and the limit pin 313 can be used to limit the moved movable guide roller 311.

[0031] During use, first wind the electrostatic film around the surface of the material roller structure 2, and then start the material roller structure 2, so that the material roller structure 2 conveys the electrostatic film, and the electrostatic film passes through the material roller structure 2, the guiding structure 3, the conveying structure 4, the cutting mechanism 5 and the storage roller 6 in sequence. The material roller structure 2, the cutting mechanism 5 and the storage roller 6 are all driven by an external power supply, so that the electrostatic film can be stably conveyed in the material roller structure 2 and can be sent into the receiving groove 7 through the storage roller 6 after being cut;

[0032] First, measure the thickness of the electrostatic film. Subsequently, adjust the interval between the fixed guide roller 309 and the movable guide roller 311 according to this thickness. Pull out the limit pin 313 outward, so that the movable guide roller 311 can slide along the direction of the chute 310, and the interval between the fixed guide roller 309 and the movable guide roller 311 is adjusted. Subsequently, insert the limit pin 313 into the corresponding limit hole 312 again, so that the fixed guide roller 309 and the movable guide roller 311 are repositioned, and at this time, the fixed guide roller 309 and the movable guide roller 311 can clamp the electrostatic film therein;

[0033] Then, adjust the interval between the two groups of fixed collars 305 and movable collars 308 according to the width of the electrostatic film. Drive the double - shaft screw 303 to rotate through the built - in motor. Since two sections of thread grooves with opposite directions are provided on the surface of the double - shaft screw 303, the two thread blocks 304 are respectively thread - connected to the two thread grooves, so the two thread blocks 304 will move relatively, causing the thread blocks 304 to drive the fixed collars 305 and the movable collars 308 to move synchronously. Also, because the fixed collars 305 and the movable collars 308 are slidably connected through the slide rails 306 and the insertion rods 307, the interval between the fixed collars 305 and the movable collars 308 on the same side can be synchronously adjusted according to the interval between the fixed guide roller 309 and the movable guide roller 311, so that the fixed collar 305 can slide along the surface of the fixed guide roller 309, and the movable collar 308 can slide along the surface of the movable guide roller 311, and at this time, the electrostatic film can be clamped between the fixed guide roller 309, the movable guide roller 311, the fixed collar 305 and the movable collar 308;

[0034] When the cutting position of the electrostatic film moves below the driving frame 501, start the cutting mechanism 5, so that the hydraulic cylinder drives the cutting knife 502 to descend, and the cutting knife 502 starts to perform slitting processing on the electrostatic film.

[0035] In summary, for the slitting device for PE electrostatic film production, by setting the guiding structure 3, the high - end of the driving box 301 is lapped, and the built - in motor can drive the two thread blocks 304 to drive the fixed collars 305 and the movable collars 308 to move towards each other through the double - shaft screw 303, so that the two fixed collars 305 and the movable collars 308 can adjust the interval between them according to the width of the electrostatic film, prompting the two groups of fixed collars 305 and the movable collars to perform adaptive limiting on the electrostatic film, positioning the electrostatic film, avoiding the situation that the electrostatic film is prone to position deviation before cutting, and preventing the electrostatic film from being loose, wrinkled and uneven during cutting, enabling the device to accurately cut the electrostatic film.

[0036] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
