[0022] In order to make the purpose and advantages of the utility model more clear and obvious, the utility model is specifically described below in combination with examples. It should be understood that the following text is only used to describe one or several specific embodiments of the utility model, and does not strictly limit the protection scope of the utility model.

[0023] As Figures 1-3 Shown, a kind of paper product preparation with the edge pressing device with anti-deviation structure, including support 1, turnover pressing assembly 2, two clamping plates 3 and edge pressing assembly, turnover pressing assembly 2 and edge pressing assembly are set on support 1, turnover pressing assembly 2 is set in edge pressing assembly, two clamping plates 3 are installed on support 1, and with turnover pressing assembly 2 symmetrically set with edge pressing assembly as center.

[0024] The turnover compression assembly 2 comprises a rotating shaft 21, two turnover plates 26, a reverse pulling assembly, an elastic roller compression assembly a, and a clamping assembly. The elastic roller compression assembly a is arranged on the two turnover plates 26, one side of each of the two turnover plates 26 is mounted on the rotating shaft 21, two fixed plates 22 are mounted on the support 1, the rotating shaft 21 is rotatably mounted on the two fixed plates 22, the clamping assembly is arranged on the other side of the two turnover plates 26, and the reverse pulling assembly is arranged on the rotating shaft 21 and provides a reverse pulling force to the turnover plates 26 and the clamping assembly.

[0025] The reverse pulling assembly comprises two reverse pulling plates 23, a bolt 24, and a reverse pulling elastic member 25. The two reverse pulling plates 23 are fixedly mounted on the rotating shaft 21. The bolt 24 is limitingly mounted on the right side of the two reverse pulling plates 23 through a threaded nut. The upper end of the reverse pulling elastic member 25 is sleeved on the bolt 24, and the lower end is sleeved in a circular hole formed in the side plate of the support 1. The reverse pulling elastic member 25 is a hook spring.

[0026] As an optional embodiment, the elastic roller compression assembly a is provided in two and arranged between the two turnover plates 26. The elastic roller compression assembly a comprises a mounting plate a1, an edge compression roller a2, a sliding rod a4, and a buffer elastic member a5. One end of the sliding rod a4 is limitingly mounted on the mounting plate a1 through a threaded nut. The mounting plate a1 is fixedly arranged between the two turnover plates 26. The two ends of the edge compression roller a2 are rotatably mounted on two stable plates a3. The other end of the sliding rod a4 is fixedly welded on the stable plate a3. The buffer elastic member a5 is sleeved on the sliding rod a4 and arranged between the mounting plate a1 and the stable plate a3. The buffer elastic member a5 is a spring. In this way, the edge compression roller a2 is elastically buffered by the buffer elastic member a5, which facilitates the compression roller to compress paper products of different thicknesses, thereby improving the application effect.

[0027] Referring to the accompanying drawings Figure 2 The clamping assembly comprises a translation plate 28 and two smooth shafts 29. The two smooth shafts 29 are slidingly mounted on a reinforcing plate 27. The reinforcing plate 27 is fixedly arranged on the other side of the two turnover plates 26. The two ends of the translation plate 28 are fixedly connected with one end of the two smooth shafts 29, respectively. The other end of the smooth shaft 29 is threadedly connected with a nut and located between the two turnover plates 26. In this way, the reinforcing plate 27 provides displacement adjustment support to the translation plate 28 through the smooth shaft 29, so that the clamping assembly restricts the elastic roller compression assembly a on the turnover plate 26 after the clamping assembly cooperates with the clamping plate 3, thereby improving the roller compression effect on the edge-compressed paper product.

[0028] Referring to the accompanying drawings Figure 1The edge pressing assembly comprises a fixing frame 4, a hydraulic cylinder 5, an edge pressing die 6 and guide rail rods 7. The hydraulic cylinder 5 is fixedly installed on the fixing frame 4, the fixing frame 4 is arranged on the support 1, the edge pressing die 6 is arranged at the lower side inside the fixing frame 4 and is installed on the extending end of the hydraulic cylinder 5, the guide rail rods 7 are arranged in two and are slidably installed on the fixing frame 4, the upper end of the guide rail rod 7 is threadedly connected with a nut, and the lower end is fixedly installed on the edge pressing die 6. Thus, the hydraulic cylinder 5 pushes the edge pressing die 6 to slide downward under the limitation of the guide rail rod 7 to perform edge pressing treatment on the paper product.

[0029] Further, the two turnover plates 26 are arranged in the fixing frame 4, the length of the turnover plate 26 is arranged as 0.9 times the distance between the fixed plate 22 and the clamping plate 3. Thus, the turnover plate 26 can be clamped and adjusted in correspondence with the clamping plate 3 after being rotated.

[0030] Further, when the translation plate 28 rotates with the pivot 21 as the center, the clamping and adjusting can be matched with the clamping plate 3 through the sliding adjustment of the smooth shaft 29. Thus, the translation plate 28 can clamp and limit the turnover plate 26 driven by the reverse pulling assembly, so that the elastic roller pressing assembly a performs the roller pressing operation on the paper product.

[0031] Further, the sum of the lengths of the smooth shaft 29 and the turnover plate 26 is arranged as 1.3 times the distance from the fixed plate 22 to the side of the clamping plate 3. Thus, after the translation plate 28 is rotated by the turnover plate 26, it is ensured that the translation plate 28 is clamped in the clamping plate 3 to form the clamping and limiting.

[0032] With the above structure, when the operator holds down the turnover plate 26, the edge pressing roller a2 in the elastic roller pressing assembly a is driven to press the paper product; at the same time, the translation plate 28 of the clamping and adjusting assembly is matched with the clamping plate 3 to form automatic clamping and adjusting, effectively limiting the rebound effect of the reverse pulling assembly on the turnover plate 26. Specifically, 1. when the translation plate 28 is pulled downward, the turnover plate 26 is rotated with the pivot 21 as the center; 2. the turnover plate 26 is rotated to synchronously drive the edge pressing roller a2 to descend to the working position; 3. the reverse pulling elastic member 25 is stretched during the rotation of the pivot 21 to generate a reset pulling force; 4. after the edge pressing roller a2 contacts the paper product, the self-adaptive pressing force is formed by compressing the buffer elastic member a5 through the sliding rod a4; 5. the whole mechanism remains in a stable working state under the clamping and adjusting. Thus, the convenient fixing and releasing operation can be realized.
