[0023] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figures 1 to 4 As shown, a transfer device for EVA film production and processing includes: a bottom plate 4, a sleeve tube 6 and a support plate 5,

[0025] The side end of the bottom plate 4 is fixedly connected to a driving machine 1, and a plurality of traction rollers 3 are detachably installed on the side end of the driving machine 1. The traction roller 3 is fixedly connected to a fixed limiting plate 2 at the side end close to the driving machine 1. The bottom plate 4 has a load-bearing connection function for the driving machine 1. The driving machine 1 is used to drive the traction roller 3 to rotate. The driving machine 1 drives the traction roller 3 to rotate, and the EVA film is tightly attached to the traction roller 3. The rotation of the traction roller 3 drives the EVA film to be transported, thereby achieving the effect of transporting the EVA film. The fixed limiting plate 2 fixedly connected to the side end of the traction roller 3 close to the driving machine 1 rotates together with the traction roller 3, and the fixed limiting plate 2 limits the side end of the transported EVA film to prevent the EVA film from deviating toward the driving machine 1 on the traction roller 3; it also includes:

[0026] The sleeve tube 6 is sleeved and connected to the side end of the traction roller 3 away from the driving machine 1, and the side end of the sleeve tube 6 close to the driving machine 1 is fixedly connected with a movable limit plate 10. The sleeve tube 6 moves on the traction roller 3, thereby realizing the effect of moving and adjusting the movable limit plate 10 on the traction roller 3. The movable limit plate 10 limits the other end of the EVA film away from the driving machine 1, thereby ensuring that the EVA film will not deviate when being transported on the traction roller 3, thereby avoiding the problems of uneven roll surface, rib burst, wrinkles, inclined edges, etc. when the EVA film is rolled up; and

[0027] The support plate 5 is fixedly connected to the side end of the base plate 4 away from the driving machine 1. A plurality of limiting holes 12 are opened on the top of the support plate 5 in parallel with the center line of the traction roller 3. The support plate 5 is connected to the driving machine 1 through the base plate 4. The support plate 5 provides support and limiting functions for the traction roller 3 and the sleeve tube 6.

[0028] In some specific implementation schemes, the fixed limit plate 2 is not in contact with the driving machine 1, and the fixed limit plate 2 is in the shape of a circular ring. The circular ring shape of the fixed limit plate 2 ensures that the fixed limit plate 2 can follow the rotation of the traction roller 3 to limit the EVA film. The fixed limit plate 2 and the driving machine 1 are not in contact, so that the traction roller 3 can be detachable on the driving machine 1.

[0029] In some specific embodiments, the traction roller 3 is provided with a threaded hole 9 at the side end away from the driving machine 1, and a threaded rod 11 is threadedly connected inside the threaded hole 9. The sleeve tube 6 is fixedly connected with a circular plate 7 at the side end away from the driving machine 1. The threaded hole 9 provided in the traction roller 3 provides a threaded fixing function, and the threaded rod 11 has a connecting structure function.

[0030] In some specific implementation schemes, the circular plate 7 is fixedly connected with a nut 8 at the side end away from the driving machine 1, and the circular plate 7 is fixedly connected with the threaded rod 11 at the side end close to the driving machine 1. By controlling the rotation of the nut 8, the nut 8 drives the circular plate 7 to rotate, and the circular plate 7 drives the sleeve tube 6 and the threaded rod 11 to rotate. The threaded rod 11 rotates and moves in the threaded hole 9, thereby driving the sleeve tube 6 to rotate and move on the traction roller 3, and the sleeve tube 6 drives the movable limit plate 10 to move on the traction roller 3, thereby realizing the movable limit. The plate 10 is adjustable, and the movable limit plate 10 moves according to the width of the EVA film, thereby improving the applicability of the movable limit plate 10. When the nut 8 stops rotating, the threaded connection between the threaded rod 11 and the threaded hole 9 has a fixing effect, and the threaded rod 11 transfers the threaded fixation to the sleeve tube 6 through the circular plate 7, thereby ensuring that the sleeve tube 6 is fixed on the traction roller 3. When the traction roller 3 rotates, the traction roller 3 drives the sleeve tube 6 to rotate through the threaded rod 11, and the sleeve tube 6 drives the movable limit plate 10 to rotate.

[0031] In some specific embodiments, the limiting hole 12 completely penetrates the top of the support plate 5, and the limiting hole 12 is rotationally connected to the sleeve tube 6. The limiting hole 12 completely penetrates the support plate 5 to ensure that the sleeve tube 6 can be adjusted in the limiting hole 12. The limiting hole 12 transmits the limiting effect of the sleeve tube 6 generated by the rotational connection to the traction roller 3, thereby ensuring the rotation stability of the traction roller 3.

[0032] In some specific embodiments, the movable limit plate 10 is in a circular ring shape, and the movable limit plate 10 is sleeved and connected to the traction roller 3. The circular ring shape of the movable limit plate 10 can ensure that the movable limit plate 10 limits the side end of the EVA film when rotating, and the sleeve connection between the movable limit plate 10 and the traction roller 3 ensures that the movable limit plate 10 can move on the traction roller 3.

[0033] In order for those skilled in the art to better understand the working principle of the embodiments of the present invention, the following is an explanation in conjunction with specific application scenarios:

[0034] The control nut 8 is rotated, and the nut 8 drives the circular plate 7 to rotate, and the circular plate 7 drives the sleeve tube 6 and the threaded rod 11 to rotate, and the threaded rod 11 rotates and moves in the threaded hole 9, thereby driving the sleeve tube 6 to rotate and move on the traction roller 3, and the sleeve tube 6 drives the movable limit plate 10 to move on the traction roller 3, so that the movable limit plate 10 is adjustable, and the movable limit plate 10 moves according to the width of the EVA film, thereby improving the applicability of the movable limit plate 10, when the nut 8 stops rotating, the threaded connection between the threaded rod 11 and the threaded hole 9 has a fixing effect, and the threaded rod 11 transfers the thread fixation to the sleeve tube 6 through the circular plate 7, thereby ensuring that the sleeve tube 6 is fixed on the traction roller 3, when the traction roller When the EVA film is tightly attached to the traction roller 3 for transportation, the fixed limiting plate 2 fixedly connected to the side end of the traction roller 3 close to the driving machine 1 rotates with the traction roller 3, and the fixed limiting plate 2 limits the side end of the transported EVA film to prevent the EVA film from deviating toward the driving machine 1 on the traction roller 3, and the movable limiting plate 10 limits the other end of the EVA film away from the driving machine 1, thereby ensuring that the EVA film will not deviate when being transported on the traction roller 3, thereby avoiding problems such as uneven roll surface, rib burst, wrinkles, tilted edges, etc. when the EVA film is rolled up;

[0035] Among them, the limiting hole 12 is rotationally connected with the sleeve tube 6, and the limiting hole 12 completely penetrates the support plate 5 to ensure that the sleeve tube 6 can be adjusted in the limiting hole 12. The limiting hole 12 transmits the limiting effect of the sleeve tube 6 generated by the rotational connection to the traction roller 3, thereby ensuring the rotation stability of the traction roller 3. The movable limiting plate 10 is in a circular ring shape to ensure that the movable limiting plate 10 limits the side end of the EVA film during rotation. The sleeve connection between the movable limiting plate 10 and the traction roller 3 ensures that the movable limiting plate 10 can move on the traction roller 3. The threaded hole 9 opened on the traction roller 3 provides a threaded fixing function, and the threaded rod 11 has the function of a connecting structure.

[0036] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
