DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0018] In the description of the embodiments of the utility model, it needs to be explained that, unless there is definite stipulation and limitation, the term "mounting", "connection" should be understood in broad sense, for example, it can be fixed connection, also can be detachable connection, or integrally connected, can be direct connection, also can be indirect connection through intermediate medium, can be the intercommunication of two elements inside. For ordinary skilled in the art, the specific meaning of the above-mentioned term in the utility model can be understood according to specific circumstances.

[0019] Referring to Figures 1-5 A winding paper-pressing structure, comprising a support 1 and a waste collecting shaft 2, further comprising a press roller 3, a connecting piece 4, a rotating shaft 5, a steel wire rope 6 and a counterweight 7, one end of the waste collecting shaft 2 is mounted on the support 1, one end of the press roller 3 is connected with one end of the connecting piece 4, the other end of the connecting piece 4 is connected with one end of the rotating shaft 5, the rotating shaft 5 is mounted on the support 1, the other end of the rotating shaft 5 is connected with one end of the steel wire rope 6, the other end of the steel wire rope 6 is connected with the counterweight 7, and the press roller 3 swings with the change of the winding diameter of the waste collecting shaft 2.

[0020] By setting the connecting piece 4 and the rotating shaft 5, stable support and guidance are provided for the press roller 3, so that the press roller 3 can swing on the set path. By setting the steel wire rope 6 and the counterweight 7, the pressure applied to the press roller 3 can be automatically adjusted according to the change of the winding diameter of the waste collecting shaft 2. When the winding diameter increases, the counterweight 7 naturally descends, and drives the press roller 3 to swing upward through the steel wire rope 6 and the rotating shaft 5, so as to reduce the pressure on the material; when the winding diameter decreases, the counterweight 7 rises, so as to increase the pressure of the press roller 3 on the material. The press roller 3 swings with the change of the winding diameter of the waste collecting shaft 2, so that the press roller 3 can always properly contact and press the material in the whole winding process, so as to prevent the material from deviating or wrinkling when winding, thereby ensuring the flatness of winding. The problem that the die-cutting waste collecting winding shaft cannot be wound with large tension, resulting in uneven winding, is solved.

[0021] In some embodiments, referring to Figures 3-4 The one end of the rotating shaft 5 close to the steel wire rope 6 is provided with a first limiting piece 51, one side of the support 1 close to the first limiting piece 51 is provided with a second limiting piece 11 and a third limiting piece 12, the first limiting piece 51, the second limiting piece 11 and the third limiting piece 12 are all located in the same plane and are all used for limiting the rotation range of the rotating shaft 5.

[0022] The first limiting piece 51, the second limiting piece 11 and the third limiting piece 12 jointly limit the swing range of the rotating shaft 5 and the press roller 3, so that the press roller 3 always moves on the predetermined path, and the excessive rotation of the rotating shaft 5 caused by external factors, such as sudden tension change or mechanical failure, is avoided, thereby protecting the winding paper-pressing structure. Referring to Figure 3 When the winding diameter of the waste collecting shaft 2 is small, the counterweight 7 rises, the press roller 3 presses downward, and the first limiting piece 51 is close to the second limiting piece 11; referring to Figure 4When the winding diameter of the waste roll is large, the counterweight 7 is lowered, the compression roller 3 is lifted, and the first limiting piece 51 is close to the third limiting piece 12.

[0023] In some embodiments, referring to Figure 3 , the support 1 is provided with a guide roller 8 on one side close to the steel wire rope 6, referring to Figure 5 , the guide roller 8 comprises a connecting rod 81 and a rotating wheel 82, one end of the connecting rod 81 is fixedly connected with the support 1, the other end of the connecting rod 81 is rotationally connected with the rotating wheel 82, and the outer side of the rotating wheel 82 is provided with a concave ring 83.

[0024] The guide roller 8 is used to guide the path of the steel wire rope 6, and ensure that the steel wire rope 6 moves along the predetermined path without deviation or winding; the design of the rotating wheel 82 enables the steel wire rope 6 to smoothly slide thereon, reducing the friction between the steel wire rope 6 and the rotating wheel 82, and the concave ring 83 further enhances the positioning effect on the steel wire rope 6, preventing the steel wire rope 6 from slipping off the rotating wheel 82.

[0025] In some embodiments, referring to Figure 1 , the length of the connecting piece 4 is not less than the distance between the rotating shaft 5 and the waste collecting shaft 2.

[0026] The length of the connecting piece 4 is set to provide sufficient movement space for the compression roller 3, so that the compression roller 3 can freely swing up and down to flexibly adjust the position according to the change of the winding diameter of the waste collecting shaft 2, thereby more evenly applying pressure to the material.

[0027] In some embodiments, the counterweight 7 is a cast iron weight.

[0028] Since the weight of the cast iron weight can be accurately controlled, it is beneficial to achieve more delicate and stable tension adjustment, thereby improving the winding quality; in addition, the cast iron weight can provide a relatively large weight in a relatively small volume, so that the cast iron weight can achieve the required counterweight effect in a limited space, ensuring stable operation of the system.

[0029] In the description of the embodiments of the present application, the terms "first", "second", "third" are used only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second", "third" can explicitly or implicitly include one or more of the features.

[0030] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
