A reciprocating shifting winding device

Abstract

This utility model discloses a reciprocating shifting winding device, including a base plate, on which two sliding plates are mounted on the base plate. Mounting plates are fixed to the front and rear sides of the two sliding plates respectively. A controllable rotating winding roller is rotatably connected between the front and rear mounting plates. The two sliding plates are slidably connected to the base plate. The device also includes a shifting drive mechanism for controlling the reciprocating motion of the sliding plates. This utility model enables the mounting plates and the winding roller between them to undergo periodic reciprocating motion during the winding process, avoiding the finished film roll being thick at both ends and thin in the middle, and also preventing uneven film thickness at a certain position due to different die head gaps, thus preventing bulging phenomena in the film roll and improving product quality. The frequency of the reciprocating motion of the mounting plates and the winding roller in this utility model can be adjusted to adapt to different working conditions.

Description

Technical Field

[0001] This utility model relates to the field of winding technology, and in particular to a reciprocating shifting winding device. Background Technology

[0002] Lamination is a process in which a plastic film is coated with adhesive, bonded to paper, and then pressed together by rubber rollers and heated rollers to form a paper-plastic composite product.

[0003] After the product is laminated, it needs to be rolled up for storage and transportation. Currently, the winding device in a laminating machine generally includes a frame, a winding shaft, and a winding motor. The winding motor is mounted on the frame, and the winding shaft is detachably mounted on the frame and connected to the winding motor for transmission. During operation, the winding motor drives the winding shaft to rotate continuously, and performs edge winding (that is, accurately superimposing the corresponding edge parts of the film) on the film conveyed by the traction device to form a film roll.

[0004] However, in actual production, two situations often occur: one is that the edge of the finished film material after lamination is slightly thicker than the middle part. When the above-mentioned winding device is used to wind the finished film material, the edge of the finished film material is often superimposed, resulting in the wound film roll being thick at both ends and thin in the middle.

[0005] One cause is uneven film thickness at a certain location due to different die head gaps, resulting in bulging ribs on the wound film roll and consequently, poor flatness of the film roll surface material.

[0006] Therefore, in response to the above phenomenon, it is necessary to improve the winding device inside the laminating machine. Utility Model Content

[0008] This utility model provides the following technical solution: a reciprocating shifting winding device, including a base plate, on which two sliding plates are mounted on the base plate and are distributed on the left and right sides. The front and rear sides of the two sliding plates are respectively fixed with mounting plates, and a winding roller that can be rotated in a controlled manner is rotatably connected between the front and rear mounting plates.

[0010] Preferably, the base plate has four horizontal guide rails extending in the front-to-back direction, and each of the slide plates is rotatably connected to two rollers extending to the underside of the slide plate and distributed in the front-to-back direction. The rollers roll in cooperation with the guide rails.

[0012] Preferably, the cam is a disc-shaped constant-diameter cam.

[0013] Preferably, the vertical width of the adapter groove is greater than the diameter of the cam.

[0014] Preferably, the motor integrates a speed reducer.

[0015] Preferably, a guide roller is provided between the front and rear mounting plates, and the film material is wound around the guide roller and then rolled onto the take-up roller.

[0016] This utility model provides a reciprocating shifting winding device, which has the following beneficial effects:

[0017] This invention enables the mounting plate and the winding roller between the mounting plates to undergo periodic back-and-forth reciprocating motion during the winding process, avoiding the situation where the finished film roll is thick at both ends and thin in the middle, and also avoiding uneven film thickness at a certain position due to different die head gaps, thus preventing the bulging phenomenon of the film roll and improving product quality.

[0027] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] Reference Figures 1-6According to an embodiment of the reciprocating shifting winding device of the present invention, it includes a base plate 11, on which two sliding plates 12 are mounted on the base plate 11 and distributed on the left and right. The front and rear sides of the two sliding plates 12 are respectively fixed with mounting plates 13. A winding roller 14 that can be controlled to rotate is rotatably connected between the front and rear mounting plates 13. A paper tube that can be detached and locked relative to the winding roller 14 is provided on the outer sleeve of the winding roller 14. When the winding roller 14 is controlled to rotate, it can drive the paper tube to rotate, thereby winding the film material. This is a conventional setting in the prior art and will not be described in detail here. In addition, in order to ensure the stability of the film material during the winding process, a guide roller 20 is also provided between the front and rear mounting plates 13. The film material is wound around the guide roller 20 and then wound around the winding roller 14.

[0032] The two slide plates 12 are slidably connected to the base plate 11, and the system also includes a displacement drive mechanism for controlling the reciprocating motion of the slide plates 12.

[0033] During the winding process, the slide plate 12 is controlled by the displacement drive mechanism to perform periodic back-and-forth movements, which in turn drive the mounting plate 13 and the winding roller 14 to move, thereby improving the flatness of the wound film roll surface material, avoiding the situation where the ends are thick and the middle is thin due to the overlapping of the edges of the finished film roll, and also avoiding the situation where the film thickness is uneven at a certain position due to different die head gaps, and then overlapping, resulting in bulging of the wound film roll.

[0034] The specific connection method between the sliding plate 12 and the base plate 11 is as follows: Figure 4 As shown, four horizontal guide rails 15 extending in the front-to-back direction are arranged in an array on the base plate 11. Each slide plate 12 is rotatably connected to two rollers 16 extending to the lower side of the slide plate 12 and distributed in the front-to-back direction. The rollers 16 roll in cooperation with the guide rails 15.

[0035] Furthermore, in this embodiment, such as Figure 3 As shown, the shifting drive mechanism includes a shifting seat 17 fixed on the slide plate 12, an adapter groove is provided in the shifting seat 17, and a motor 18 is also mounted on the base plate 11. An eccentrically arranged cam 19 is fixed on the output shaft of the motor 18. The cam 19 extends into the adapter groove and the outer contour of the cam 19 is tangentially connected to the front and rear sides of the adapter groove. Specifically, the cam 19 is a disc-shaped equal-diameter cam.

[0036] When the motor 18 is energized and drives the cam 19 to rotate eccentrically, it will cause the shift seat 17, the slide plate 12 and the mounting plate 13 to move back and forth periodically, thereby improving the winding effect.

[0037] Furthermore, the vertical width of the adapter groove is greater than the diameter of the cam 19 to avoid additional friction.

[0038] In this embodiment, the motor 18 integrates a speed reducer to increase the driving torque on the cam 19 and improve motion stability. Furthermore, the rotational speed of the output shaft in the motor 18 can be adjusted to adjust the frequency of the back-and-forth swing of the slide plate 12, the mounting plate 13, and the take-up roller 14.

[0039] It should be noted that the mounting plate 13 is equipped with weights such as the take-up roller 14, which prevents the mounting plate 13 from being lifted when the cam 19 rotates, and instead causes it to move back and forth.

[0040] The above description is only a specific embodiment of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
