SUMMERY OF THE UTILITY MODEL

In order to solve the technical problems, the utility model aims to provide the plastic film die-cutting machine roller, which is suitable for and can accommodate various plastic films with different widths, so that the production is ensured without replacing another roller, and the cost of equipment is saved.

In order to achieve the purpose, the roller of the plastic film die-cutting machine comprises a rotating shaft, two cylinders and a plurality of base plates, wherein a baffle is arranged at the right end of the rotating shaft, a screw is arranged on the right side of the baffle, and the screw is in threaded connection with a nut;

the cylinder body is of a cylindrical structure, and a through hole is formed in the side surface of the cylinder body to communicate two end surfaces of the cylinder body;

the base plate is of a cylindrical structure, and the side surface of the base plate is provided with the through hole to communicate the two end surfaces of the base plate;

the end face of the backing plate is consistent with the end face of the barrel in size, and the through hole is matched with the screw rod to enable the barrel, the backing plate and the screw rod to be in sliding connection.

Furthermore, a guide rail is arranged on one end face of the cylinder body.

Furthermore, the end faces at the two ends of the cylinder body adopt an anti-skid design.

Furthermore, the right end of the screw rod is designed in a square shape.

Furthermore, the rotating shaft, the baffle and the screw rod are designed in an integrated mode.

Compared with the prior art, the utility model has the beneficial effects that:

the two cylinders are sleeved between the upper baffle plate of the screw and the nut, the nut is fastened again, the cylinders and the rotating shaft are fixed and can rotate along with the rotation of the rotating shaft, the cylinders can rotate to complete rolling, unreeling and other works, when wide plastic films need to be processed, the nut and one cylinder are dismounted, a proper amount of base plates are sleeved on the screw, the dismounted cylinders and the nut are mounted on the screw, and the two cylinders are filled with proper amount of base plates to increase the length of the whole roller so as to adapt to the wide plastic films.

In conclusion, the plastic film die-cutting machine roller is adopted, and plastic films with various different widths can be adapted and accommodated, so that the production is guaranteed without replacing other rollers, and the cost of equipment is saved.

Detailed Description

To explain the technical content, structural features, attained objects and effects of the present invention in detail, embodiments are described below in detail with reference to the accompanying drawings.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate orientations or positional relationships based on those shown in the drawings, and are used merely for convenience in describing the present invention and for simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be taken as limiting the scope of the present invention.

Referring to fig. 1 and fig. 2, the present invention provides an embodiment:

the utility model provides a plastic film die-cutting machine roller for achieving the purpose, which comprises a rotating shaft 1, two cylinders 2 and a plurality of backing plates 3, wherein a baffle 4 is arranged at the right end of the rotating shaft 1, a screw rod 5 is arranged on the right side of the baffle 4, and the screw rod 5 is in threaded connection with a nut 6;

the cylinder body 2 is of a cylindrical structure, and a through hole 7 is formed in the side surface of the cylinder body 2 to communicate two end surfaces of the cylinder body 2;

the backing plate 3 is of a cylindrical structure, and the through hole 7 is formed in the side surface of the backing plate 3 to communicate the two end surfaces of the backing plate 3;

the end face of the backing plate 3 is consistent with the end face of the cylinder 2 in size, and the through hole 7 and the screw rod 5 are matched with each other to enable the cylinder 2, the backing plate 3 and the screw rod 5 to be in sliding connection.

With two barrel 2 suits on screw rod 5 between baffle 4 and nut 6, fasten nut 6 again and let barrel 2 and pivot 1 fixed can rotate along with the rotation of pivot 1, barrel 2 rotates alright completion rolling, work such as unreel, when needing to process the plastic film of broad, pull down nut 6 and a barrel 2, suit the screw rod 5 with appropriate amount backing plate 3 on, install the barrel 2 and the nut 6 that will pull down again on screw rod 5, let to fill between two barrels 2 and have appropriate amount backing plate 3 to increase the length of whole roller and be used for adapting to the plastic film of broad.
