[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0022] refer to Figure 1-5 A positioning auxiliary device for a cardboard inserter includes a base plate 1, on which a conveying device 101 is mounted. A feed inlet 102 is located on one side of the conveying device 101, and positioning blocks 103 are located on both sides of the feed inlet 102. Positioning cylinders 104 are located on opposite sides of the two positioning blocks 103. A positioning mechanism for positioning cardboard is located on the side of the positioning cylinder 104 away from the positioning blocks 103. The positioning cylinder 104 is connected to the positioning blocks 103 via a support plate. Bolts are threaded onto the four corners of the support plate. Connecting the support plate to the positioning blocks 103 via bolts enables the positioning mechanism to be detachable. When not in use, the positioning mechanism can be disassembled, thereby reducing maintenance costs. The positioning mechanisms on both sides are symmetrically arranged, allowing for rapid center finding without requiring manual center searching, thus improving the processing quality of the cardboard.

[0023] With the positioning block 103, positioning cylinder 104 and positioning mechanism set up, when using the inserting machine, the operator can place the cardboard between the two positioning mechanisms. The positioning mechanism can quickly position the cardboard, helping the operator to place the cardboard more accurately into the feed port 102 of the inserting machine. This ensures that the position of each cardboard is accurate and avoids offset or misalignment, thereby improving the processing quality of the cardboard. In order to make the positioning effect better, positioning cylinders 104 can be set on both sides of the positioning block 103.

[0024] Specifically, the positioning mechanism includes an elastic element 105 and a clamping block 108. The elastic element 105 is a cylindrical compression spring, which can quickly return to its original shape under force. Therefore, a cylindrical compression spring is preferred for the elastic element 105. The positioning cylinder 104 has a sliding groove 106 inside. The clamping block 108 has a slider 107 on the side near the positioning cylinder 104. The slider 107 is slidably connected to the inner wall of the sliding groove 106. The elastic element 105 is sleeved on the slider 107, and one end of the elastic element 105 is connected to the positioning cylinder 104. 04. The other end of the elastic element 105 abuts against the clamping block 108. When the operator feeds the cardboard into the inserting machine, one side of the cardboard contacts the clamping block. At this time, the clamping block 108 will move in the direction of compressing the elastic element 105, thereby driving the slider 107 to slide and connect with the inner wall of the slide groove 106. When the cardboard is completely put down, under the action of the elastic element 105, the clamping block 108 will clamp and position the side of the cardboard, so that the operator does not need to need the center point, thus improving the processing quality of the cardboard.

[0025] To facilitate the placement of cardboard by workers, a positioning groove 2 is provided on the side of the clamping block 108 away from the slider 107. The positioning groove 2 provides a place for the cardboard, making it easier and faster to clamp the cardboard in a fixed position, improving production efficiency and operational convenience. To prevent wrinkles caused by the contact between the corners of the cardboard and the corners of the positioning groove 2 during the placement process, the four sides of the positioning groove 2 are rounded. The rounded corners provide a smoother transition, reduce the contact area between the cardboard and the corners of the positioning groove 2, and thus improve the quality of cardboard processing.

[0026] To enable the positioning groove 2 to adapt to cardboard of different thicknesses and expand its application range, an adjustment groove 201 is provided on one side of the positioning groove 2. An adjustment screw 202 is rotatably connected inside the adjustment groove 201. One side of the adjustment screw 202 passes through the top of the clamping block 108 and extends to the outside of the clamping block 108. A fixing plate 203 is provided inside the adjustment groove 201. A sliding plate 204 is provided on one side of the fixing plate 203. The sliding plate 204 is threadedly connected to the adjustment screw 202 and slidably connected to the inner wall of the adjustment groove 201. When the cardboard is placed into the positioning groove 2, the top of the cardboard can be limited by rotating the adjustment screw 202 to drive the fixing plate 203, which can further prevent the cardboard from shifting and improve the processing quality of the cardboard. To facilitate the operator to rotate the adjustment screw 202, an adjustment block 205 is provided on the side of the adjustment screw 202 away from the clamping block 108. The outer surface of the adjustment block 205 is provided with anti-slip texture. The adjustment block 205 can help the operator obtain greater torque, and the anti-slip texture can increase the operator's comfort.

[0027] In order to reduce the friction between the cardboard and the fixing plate 203 and the positioning groove 2, a number of ball bearings 206 are provided on the opposite side of the fixing plate 203 and the positioning groove 2. The ball bearings 206 can reduce the friction between the cardboard and the fixing plate 203 and the positioning groove 2 during the movement, maintain the flatness and integrity of the cardboard surface, and thus improve the processing quality.

[0028] In this embodiment, a fixing groove 3 is provided on the top of the positioning cylinder 104. A fixing screw 301 is fixedly connected to the side of the slider 107 away from the clamping block 108, and one end of the fixing screw 301 extends out of the fixing groove. A fixing nut 302 is threadedly connected to the side of the fixing screw 301 away from the slider 107, and the fixing nut 302 abuts against the positioning cylinder 104. With the fixing screw 301 and fixing nut 302, when the operator adjusts the width of the same type of cardboard, the slider 107 can be moved by rotating the fixing nut 302. The position of the clamping block 108 is fixed in the groove 106 to prevent it from returning to its original position under the action of the elastic element 105. In order to improve the fixing effect, a shim can be set at the bottom of the fixing nut 302. The shim can increase the contact area between the fixing nut 302 and the surface of the positioning cylinder 104, thereby improving the fixing effect. When the clamping block 108 is fixed, when the worker processes another cardboard of the same model, there is no need to adjust the position of the clamping block 108. He only needs to align it with the positioning groove 2 and insert it, which makes it easier for the worker to process the cardboard and improves the production efficiency of the cardboard.

[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
