[0038] The following is combined with Figure 1 -Attached Figure 4The present application is further described in detail. In this embodiment, unless otherwise specified, the terms "connected", "connected" and "fixed" are understood in a broad sense, including fixed connection, detachable connection, connection to form an integral structure, mechanical connection, electrical connection, direct connection, indirect connection through an intermediary, internal connection and interaction between two elements, and can be understood based on the specific circumstances.

[0039] In this application, unless otherwise expressly specified and limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or the first and second features being in contact not directly but through another feature between them. Moreover, in the description of this embodiment, the terms "above", "below", "right", and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application. Unless otherwise specified, orientation words such as "inside" and "outside" used in this application refer to the outlines of the corresponding components themselves.

[0040] like Figure 1 As shown, the present invention discloses a paper pressing device for a saddle stitcher (hereinafter referred to as the "device"). The device is installed on the saddle stitcher body 100 and includes a support frame 1, a paper pressing assembly 2, and a separation assembly 3. The device is used to compact the products on the saddle stitcher body 100 to prevent them from becoming too loose.

[0041] The support frame 1 is mounted on the saddle stitcher body 100. The support frame 1 is used to mount the paper pressing assembly 2, so that the paper pressing assembly 2 can be located above the saddle stitcher body 100 so that the paper pressing assembly 2 can press the products conveyed on the saddle stitcher body 100. The saddle stitcher body 100 can convey products through a conveyor belt, so that the products move horizontally and linearly.

[0042] like Figure 1 and Figure 2As shown, the paper pressing assembly 2 includes a pressure roller body 21, a rotating shaft 22, and a support base 23. The pressure roller body 21 is used to achieve a compacting effect on the product. The support base 23 is connected to the support frame 1. The rotating shaft 22 is inserted into the pressure roller body 21, so that both ends of the rotating shaft 22 extend out of the pressure roller body 21 and rotate to connect to the support base 23, thereby achieving the installation and rotation of the pressure roller body 21. The rotation of the pressure roller body 21 reduces the risk of product jamming during compaction. The axis direction of the pressure roller body 21 is perpendicular to the conveying direction of the scissor body 100. The length of the pressure roller body 21 is greater than or equal to the width of the product. Therefore, the single pressure roller body 21 can achieve compaction of the product, reducing the risk of product damage caused by uneven force. The support base 23 can be an assembly structure of a bearing and a bearing seat, so that the rotating shaft 22 can be rotatably connected to the bearing. The bearing is arranged on the bearing seat, and the bearing seat provides support.

[0043] like Figure 1 、 Figure 2 and Figure 3 As shown, the separation assembly 3 includes a scraper 31 connected to the support base 23 and disposed on one side of the roller body 21. The length direction of the scraper 31 is parallel to the axis direction of the roller body 21. The scraper 31 is in contact with one side of the front end of the roller body 21 along the conveying direction. The scraper 31 is disposed so that after the roller body 21 presses the product, it can separate the product from the roller body 21. This reduces the problem of tearing the product during the continuous rotation of the roller due to adhesion between the product surface and the roller body 21, which affects the processing quality of the product.

[0044] Optionally, the support frame 1 is provided with chutes 11 on both sides along the conveying direction, and the support seat 23 is slidably connected to the chutes 11, so that the pressure roller body 21 can move vertically and adjust the height of the pressure roller body 21. The support seat 23 can drive the pressure roller body 21 to move vertically along the chutes 11 to adjust the vertical distance between the pressure roller body 21 and the saddle dragon body 100, thereby facilitating the application of products of different thicknesses and avoiding damage to the products caused by too small a vertical distance.

[0045] like Figure 1 、 Figure 2 and Figure 3 As shown, the paper pressing assembly 2 optionally further includes an elastic member 24. The two ends of the elastic member 24 are respectively connected to the top of the chute 11 and the top of the support base 23. The elastic member 24 can be a spring. The elastic member 24 can provide downward pressure to the support base 23, so that the pressure roller body 21 can exert downward pressure, thereby achieving a reliable compression effect on the product. Furthermore, when the support base 23 slides freely, the elastic member 24 can enable the pressure roller body 21 to compact products of different heights, thereby achieving a compression effect.

[0046] Optionally, the paper pressing assembly 2 also includes a telescopic member 25. The telescopic member 25 is arranged below the saddle stitching machine body 100, and a support rod 26 is provided on the lower side of the support base 23, and the support rod 26 connects the movable end of the telescopic member 25. The telescopic member 25 can be a structure that can achieve telescopic movement, such as a cylinder, a hydraulic cylinder, or an electric telescopic rod. The telescopic member 25 is connected to the support base 23 through the support rod 26. The telescopic member 25 can drive the support base 23 to move vertically through the telescopic movement of the telescopic member 25, thereby adjusting the vertical height between the pressure roller body 21 and the upper surface of the saddle stitching machine body 100, and then achieving compression of products of different thicknesses. At the same time, arranging the telescopic member 25 below the saddle stitching machine body 100 can make full use of the original space below the saddle stitching machine body 100 and reduce the space occupied above the saddle stitching machine body 100. It can be understood that the support rod 26 and the support base 23 are in abutment relationship. The support rod 26 is used to limit the lowest position of the support base 23, but will not affect the upward movement of the support base 23. The cooperation of the telescopic member 25, the support rod 26 and the elastic member 24 can make the upper and lower parts of the support seat 23 be affected by the force, thereby improving the stability.

[0047] like Figure 1 、 Figure 2 and Figure 3 As shown, optionally, the paper pressing assembly 2 further includes a supporting plate 27. The paper pressing assembly 2 is provided with a plurality of support rods 26, the lower ends of which are all connected to the supporting plate 27, so that the plurality of support rods 26 are evenly distributed on the supporting plate 27. The telescopic member 25 is provided on the lower side of the supporting plate 27, and the movable end of the telescopic member 25 is connected to the center of the supporting plate 27. The supporting plate 27 is used to enable a single telescopic member 25 to drive multiple support rods 26 to move vertically, thereby facilitating the synchronous adjustment of the two ends of the same pressing roller body 21, or the two ends of different pressing roller bodies 21, reducing adjustment errors, improving force balance, and enabling the axis of the pressing roller body 21 to remain horizontal, thereby optimizing the pressing effect on the product.

[0048] Optionally, the saddle stitcher body 100 is provided with a plurality of clearance holes corresponding to the support rods 26, through which the support rods 26 are movably inserted. The clearance holes enable the support rods 26 to move vertically, thereby enabling vertical movement of the pressure roller body 21. Furthermore, the provision of the clearance holes in the saddle stitcher body 100 allows for efficient space utilization and reduces horizontal space occupation.

[0049] like Figure 1 、 Figure 3 and Figure 4 As shown, the separation assembly 3 optionally further includes a connector 32, which connects the non-rotating outer surface of the support base 23 and the scraper 31. The connector 32 is spaced apart from the roller body 21 to avoid affecting the rotation of the roller body 21. The scraper 31 is connected to the support base 23 via the connector 32, allowing the scraper 31 to move with the vertical movement of the roller body 21, thereby improving ease of use.

[0050] like Figure 1 、 Figure 3 and Figure 4 As shown, the lower end width of the scraper 31 can optionally be smaller than the upper end width along the conveying direction. This gradually increases the vertical width of the scraper 31, thereby widening the gap between the product and the roller body 21 and optimizing the separation effect. The lower end surface of the scraper 31 is arc-shaped, which reduces damage to the product caused by the scraper 31 and improves the processing quality of the product. The scraper 31 is made of an antistatic material, such as an antistatic acrylic sheet, to prevent the risk of the product surface adhering to the scraper 31 due to static electricity, thereby ensuring that the scraper 31 can reliably separate the product from the roller body 21.

[0051] It can be understood that the device also includes necessary structures for connection, support, driving, positioning, limiting and control functions so that the device can operate normally; parameters such as the shape, size, material and setting quantity of each part of the device can be determined as needed as long as the corresponding functions can be achieved.

[0052] The implementation principle of a paper pressing device for a saddle stitcher in an embodiment of the present application is as follows: the height of the carrying plate 27 is adjusted by the telescopic member 25, thereby driving the support rod 26 to move the support seat 23 vertically, so as to adjust the vertical distance between the pressing roller body 21 and the upper surface of the saddle stitcher body 100, thereby being suitable for the thickness of various products; the product is conveyed on the saddle stitcher body 100, and when passing through the pressing roller body 21, the downward pressure of the pressing roller body 21 by the elastic member 24 and the vertical limiting effect of the telescopic member 25 are used to press the product, thereby improving the flatness of the product and reducing the looseness of the product; then, the scraper 31 is used to reliably separate the product from the pressing roller body 21, thereby avoiding damage caused by adhesion of the product and affecting the processing quality of the product.

[0053] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
