[0007] The receiving mechanism includes a receiving shell, the receiving shell is fixed at the front end of the conveying device, and a motor is embedded on one side of the outer wall of the receiving shell. The power output end of the motor is connected to a bidirectional threaded rod, and the bidirectional threaded rod penetrates through the outer part of one end of the inner wall of the receiving shell and is slidably connected to a slide plate. Base blocks are embedded on one side of the outer walls of the two slide plates, and trimming knives are detachably installed on the base blocks through bolts.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] The present utility model provides a technical solution:

[0026] Please refer to Figures 1 to 2 , a PVC decorative film cutting device convenient for cleaning, including a conveying equipment 1. A control console 2 is arranged on one side of the outer wall of the conveying equipment 1, and a storage mechanism 3 for storing residue and debris is arranged at the front end of the conveying equipment 1; the storage mechanism 3 includes a storage shell 301, the storage shell 301 is fixed at the front end of the conveying equipment 1, a motor 302 is embedded on one side of the outer wall of the storage shell 301, the power output end of the motor 302 is connected to a bidirectional threaded rod 303, the bidirectional threaded rod 303 penetrates through the outside of one end of the inner wall of the storage shell 301 and is slidably connected to a slide plate 304, on the outer wall of one side of the two slide plates 304 facing each other, a base 305 is embedded, and a trimming knife 306 is detachably installed on the base 305 through bolts. A draw-out shell 307 is slidably connected to the lower part inside the storage shell 301. The bidirectional threaded rod 303 is threadedly connected to the slide plate 304, and a sliding structure is formed between the slide plate 304 and the storage shell 301. One side of the bottom end of the slide plate 304 is fixed with a connecting block 4, and a support rod 5 penetrates through the inside of the connecting block 4.

[0027] By adopting the above technical solution, it is convenient to control and adjust the conveying device 1 and the storage mechanism 3 through the console 2. When the motor 302 works, the bidirectional threaded rod 303 rotates, driving the two sliding plates 304 to slide towards or away from each other along the storage shell 301. When the sliding plate 304 slides, the connecting block 4 is used along the support rod 5 to improve the stability of the sliding process, so as to clamp the material on both sides, enabling the trimming knife 306 installed on the base 305 to contact and trim the material. The trimming debris is collected by the pull-out shell 307 that can be pulled out and separated inside the storage shell 301 to avoid inconvenient cleaning. At the same time, a filter screen is installed in the pull-out shell 307, and an air extraction device adapted to the bottom end of the storage shell 301 is provided, which can drive the debris to fall downward by sucking air, avoiding the material being adsorbed and causing curling or affecting the trimming operation.

[0028] Specifically, as Figure 1 , Figure 3 and Figure 4 shown, on the other side of the opposite outer walls of the two sliding plates 304, a leveling mechanism 6 is provided. The leveling mechanism 6 includes a fixing plate 601, the fixing plate 601 is fixed on one side of the base 305 on the outer wall of the sliding plate 304. A sleeve 602 is embedded inside the fixing plate 601. A coil 604 is installed on the inner wall of the sleeve 602. An iron core 603 passes through the inside of the coil 604. A permanent magnet rod 605 is arranged below the iron core 603. One end of the permanent magnet rod 605 passing through the fixing plate 601 is fixed with an upper pressing roller 606. The leveling mechanism 6 further includes a damping spring 607. The damping spring 607 is embedded between the two sleeves 602 at the top end of the fixing plate 601. One end of the damping spring 607 passing through the fixing plate 601 is fixed with a connecting plate 608. The connecting plate 608 is fixedly connected with the permanent magnet rod 605. An elastic structure is formed between the connecting plate 608 and the fixing plate 601 through the damping spring 607. A bearing plate 9 is fixed below the fixing plate 601 on the outer wall of the sliding plate 304. A telescopic spring 8 is embedded at the top end of the bearing plate 9. The top end of the telescopic spring 8 is connected with a lower pressing roller 7.

[0029] By adopting the above technical solution, after the coil 604 inside the sleeve 602 fixed by the fixing plate 601 is energized, the iron core 603 generates magnetic force, which can push the permanent magnet rod 605, driving the connecting plate 608 to stretch the damping spring 607, making the upper pressing roller 606 contact the material on the lower pressing roller 7. At the same time, the upper pressing roller 606 extends beyond the lower pressing roller 7 by a certain length, avoiding the trimming debris from moving upward too scattered. The lower pressing roller 7 is stressed and contracts along the telescopic spring 8. The telescopic spring 8 expands and contracts along the reserved hole of the bearing plate 9 to avoid bending, thus avoiding damage to the material caused by excessive clamping. The material is leveled and tightened by the clamping of the upper pressing roller 606 and the lower pressing roller 7, avoiding shaking during trimming. When the trimming is completed, the coil 604 is disconnected, and the upper pressing roller 606 is reset through the elastic cooperation of the damping spring 607 and the connecting plate 608.

[0030] Working principle: The conveying device 1, the receiving mechanism 3 and the leveling mechanism 6 are controlled and adjusted through the console 2. The bidirectional threaded rod 303 is driven by the motor 302, so that the sliding plate 304 slides along the receiving shell 301, and is adjusted according to the width of the material, so that the trimming knife 306 touches and trims the edge. The trimming knife 306 can be replaced through the base 305 and bolts. The cut debris falls into the receiving shell 301 and is received by the pull-out shell 307. The stability of the sliding of the sliding plate 304 is improved by the sliding of the connecting block 4 along the support rod 5. When the material is conveyed, it passes between the upper pressing roller 606 and the lower pressing roller 7. By starting the coil 604 inside the sleeve 602, the iron core 603 generates magnetic force, pushes the permanent magnet rod 605 with the same magnetic pole, and drives the connecting plate 608 to make the upper pressing roller 606 touch the material on the lower pressing roller 7. It is supported by the telescopic spring 8 and the bearing plate 9 to avoid damage caused by excessive pressing. At the same time, the leveling mechanism 6 tightens the material to avoid curling at the trimmed edge. When the trimming is completed, the coil 604 is disconnected, and the damping spring 607 drives the upper pressing roller 606 to reset under the support of the fixing plate 601.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
