Description

Technical Field

[0001] The utility model belongs to the technical field of decorative film production and processing, and specifically relates to a PVC decorative film cutting device. Background Art

[0002] PVC decorative films are widely used in furniture, building decoration, advertising signs and other fields, and often need to be cut according to specific sizes or shapes. Existing PVC decorative film cutting devices can only produce PVC decorative films of specific lengths and widths, and cannot meet the diverse needs of customers and actual use.

[0003] The utility model patent with application number 202021697122 discloses a slitting machine for automatic film winding in the production of PVC film. The machine cuts the film by setting a circular blade on the transmission rod, and finally winds the film on the winding roller. However, it cannot adjust the cutting width and length of the film. Finally, the cut film is wound on a winding roller, which needs to be further separated and used later, which wastes manpower. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the PVC decorative film cutting device described in the above background technology cannot adjust the cutting length and width of the film. A new PVC decorative film cutting device is proposed, which can electrically adjust the length and width of the cut film, and the cut film can be separated and rolled up to improve production efficiency.

The cutting roller includes a roller body, two cutting rings, two limiting rings and a plurality of telescopic rods. The two limiting rings and the two cutting rings are sleeved on the outside of the roller body, and the two cutting rings are located between the two limiting rings. The two cutting rings are respectively connected to the adjacent limiting rings through telescopic rods.

[0006] In the above technical scheme, the transmission unit is used to convey the PVC film, the cutting roller is used to cut the PVC film and adjust the width of the PVC film, the first winding roller, the second winding roller and the third winding roller are used to wind up the three groups of PVC films after cutting, wherein the cutting roller can adjust the position of the cutting ring through the telescopic rod, so as to cut the PVC film into different widths, and the first winding roller, the second winding roller and the third winding roller can wind up and separate the three groups of PVC films after cutting.

[0007] Furthermore, the transmission unit includes a main transmission roller, an auxiliary transmission roller and a motor, the main transmission roller and the auxiliary transmission roller are driven by a belt, and the output end of the motor and the main transmission roller are driven by a belt.

[0008] In the above technical solution, the motor provides power for the transmission roller, the main transmission roller contacts the PVC film to drive the PVC film forward, and the auxiliary transmission roller plays a role in assisting the transmission and flattening of the PVC film.

[0009] Furthermore, the apex of the cutting ring is higher than the apex of the main transport roller.

[0010] In the above technical solution, the cutting ring is slightly higher than the PVC film, so as to cut the PVC film.

[0011] Furthermore, a roller counter is provided on the main transmission roller.

[0012] In the above technical solution, the roller counter is used to count the number of revolutions of the main transport roller, thereby calculating the conveying length of the PVC film.

[0013] Furthermore, the two transmission units are located on both sides of the cutting roller.

[0014] Furthermore, the PVC decorative film cutting device also includes two guide rollers, and the guide rollers are located between the transmission unit close to the first winding roller and the third winding roller.

[0015] In the above technical solution, the two guide rollers play a role in guiding and separating the cut PVC film.

[0016] Furthermore, the first winding roller is externally covered with a first winding drum, the second winding roller is externally covered with a second winding drum, and the third winding roller is externally covered with a third winding drum.

[0017] Furthermore, the first winding drum and the third winding drum are located on both sides of the second winding drum.

[0018] In the above technical solution, the winding drum is used to wind up the cut PVC film, wherein the first, second and third winding drums respectively correspond to winding up the PVC film on the left side of the left cutting ring, between the two cutting rings and on the right side of the right cutting ring.

[0019] Furthermore, the length of the second winding drum is greater than or equal to the distance between the two cutting rings.

[0020] Furthermore, at least two telescopic rods are provided between the cutting ring and the limiting ring, and the telescopic rods are evenly distributed along the circumference of the limiting ring.

[0021] In the above technical solution, the circumferentially uniform distribution makes the force on the cutting ring more uniform and stable.

[0022] The advantages of the utility model are:

[0023] 1. The utility model cuts the PVC film to achieve the regulation of the width of the PVC film by setting a cutting roller with freely adjustable cutting position, calculates the length of the PVC film by a roller counter, and subsequently stops the winding drum from winding the PVC film according to the calculated length to control the length of the PVC film.

[0024] 2. The utility model arranges the first winding roller, the second winding roller and the third winding roller and two guide rollers to split and cut the PVC film into three sections and rewind them separately without subsequent separation treatment. The winding drum is sleeved on the winding roller for easy loading and unloading, simple separation, and reduced workload for workers. BRIEF DESCRIPTION OF THE DRAWINGS
