Detailed implementation mode

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] The present invention provides a Figures 1-4 packaging cardboard indentation device as shown in the figure, including a workbench 1 and an indentation device 2. The indentation device 2 is an existing indentation technology, and reference can be made to the Chinese patent with the application number 202022950093.8 and the name of an indentation device for packaging cardboard, or other similar existing technologies. Therefore, in this embodiment, the indentation device 2 will not be further described. The indentation device 2 is fixedly arranged at the top of the workbench 1. Fixed structures 3 are symmetrically arranged at the top of the workbench 1. The fixed structure 3 includes a fixing rod 301, a connecting rod 302 and a control rod 306. The fixing rod 301 is fixedly arranged at the top of the workbench 1. The fixing rod 301 is used to limit the position of the packaging cardboard on the workbench 1. A connecting groove 303 is opened at the end of the fixing rod 301. The connecting rod 302 is movably inserted into the inner cavity of the connecting groove 303. A positioning component is arranged between the connecting rod 302 and the fixing rod 301. The control rod 306 is movably inserted into the outer wall of the connecting rod 302. A limiting component is arranged between the control rod 306 and the connecting rod 302. The control rod 306 is used to drive the connecting rod 302 to move horizontally at the top of the workbench 1.

[0023] As Figure 1 and Figure 2As shown in the figure, the fixed rod 301 is cylindrical. With the cooperation of the control rod 306 and the connecting rod 302, the fixed rod 301 can move horizontally on the workbench 1. Due to the setting of the arc-shaped outer wall of the fixed rod 301, when pressing and fixing the packaging cardboard, it can avoid generating large indentations on the packaging cardboard, thus avoiding the appearance of marks in places where no indentations are required. At the same time, for relatively thin packaging cardboard, the arc-shaped pressing structure can also minimize the damage to the packaging cardboard and avoid phenomena such as the breakage of the packaging cardboard caused by excessive pressure. With the setting of the fixed rod 301, the safety of packaging cardboard processing is effectively improved. At the same time, the position of the fixed rod 301 can be adjusted according to the different widths of the packaging cardboard. During the adjustment process, the control rod 306 drives the movement of the connecting rod 302, so that the fixed rod 301 can move synchronously and is in a rotating state during the movement. After the packaging cardboard is fixed, the fixation of the position of the packaging cardboard can be released by rotation. The rotation method also further avoids generating pushing and pulling forces on the packaging cardboard and avoids the breakage of the packaging cardboard due to force, effectively improving the integrity of packaging cardboard material taking.

[0024] The fixing structure 3 further includes a movable groove 307. The movable groove 307 is opened on the side inside the workbench 1 and is used to provide a moving space for the control rod 306.

[0025] As Figure 2 As shown in the figure, the number of the connecting rods 302, the connecting grooves 303 and the control rods 306 is two each, so as to be adapted to both ends of the fixed rod 301. The inner cavities of the connecting rods 302 and the connecting grooves 303 are movably inserted. When the fixed rod 301 moves, it can rotate by using the friction with the workbench 1 or the packaging cardboard. After both ends of the control rod 306 penetrate through the inner cavity of the movable groove 307, they respectively extend to both sides of the movable groove 307. The control rod 306 moves along the inner cavity of the movable groove 307 according to the state of the fixed rod 301. When the fixed rod 301 needs to move, the control rod 306 drives the connecting rod 302 to move in a direction away from the end of the fixed rod 301, so that the positioning component can release the restriction on the rotation of the fixed rod 301. When the control rod 306 moves towards both sides of the workbench 1, it can promote the movement of the fixed rod 301 while rotating. When the position of the fixed rod 301 needs to be fixed, the control rod 306 is moved in the opposite direction along the movable groove 307, and the positioning component can restrict the position of the fixed rod 301.

[0026] The positioning component includes a positioning block 304 and a positioning groove 305. The positioning groove 305 is opened on one side of the connecting groove 303. The inner cavity of the positioning groove 305 is communicated with the inner cavity of the connecting groove 303. The positioning block 304 is fixedly arranged at one end of the connecting rod 302. The positioning block 304 is inserted and fitted into the inner cavity of the positioning groove 305. The cross-sections of both the positioning block 304 and the positioning groove 305 are rectangular, and the cross-sections of both the connecting rod 302 and the connecting groove 303 are circular.

[0027] As Figure 2 and Figure 3 shown in the figure, the positioning block 304 is fixedly arranged with the connecting rod 302. The positioning block 304 moves as the position of the connecting rod 302 changes. The setting that the inner cavity of the positioning groove 305 is communicated with the inner cavity of the connecting groove 303 enables the positioning block 304 to move into the inner cavity of the positioning groove 305 after passing through the inner cavity of the connecting groove 303 when the positioning block 304 moves towards the end of the fixed rod 301 along with the connecting rod 302. Thus, due to the shape setting, the positioning block 304 is fitted into the inner cavity of the positioning groove 305. Furthermore, the fitting of the positioning block 304 into the inner cavity of the positioning groove 305 can restrict the rotation of the fixed rod 301, preventing the fixed rod 301 from continuing to rotate. Therefore, when the fixed rod 301 presses and fixes the packaging cardboard, the stability of the pressing on the packaging cardboard can be enhanced, and it can be avoided that the packaging cardboard easily shifts in position due to the rotation of the fixed rod 301 when being processed by the indentation device 2, effectively improving the stability of the fixed rod 301 in fixing the position of the packaging cardboard. At the same time, the volume of the connecting groove 303 is larger than the size of the positioning block 304, so that when the positioning block 304 moves towards the outside of the end of the fixed rod 301 along with the connecting rod 302, when the positioning block 304 moves into the inner cavity of the connecting groove 303, it does not affect the rotation of the fixed rod 301.

[0028] The limiting component includes two limiting rings 308. Both of the two limiting rings 308 are sleeved on the outer wall of the control rod 306, and the two limiting rings 308 are respectively arranged on both sides of the connecting rod 302.

[0029] As Figure 2 shown in the figure, the limiting rings 308 are all threadedly inserted and connected with the control rod 306. The limiting rings 308 are fixedly sleeved on the outer wall of the control rod 306 through threaded connection, so that after the control rod 306 penetrates through the outer wall of the connecting rod 302, the stability of their inserted connection can be maintained. And limiting rings 308 are arranged on both sides of the connecting rod 302, enabling the connecting rod 302 to maintain the stability of their connection during the horizontal reciprocating movement along with the control rod 306. Thus, it effectively guarantees the movement of the fixed rod 301. At the same time, it also enables the control rod 306 and the connecting rod 302 to be disassembled and assembled separately. Furthermore, on the basis that the connecting rod 302 can be removed, the fixed rod 301 can also be removed. Therefore, it provides convenience for the disassembly, assembly and replacement of the fixed rod 301.

[0030] At the end of the control rod 306 facing away from the connecting rod 302, a support structure 4 is provided. The support structure 4 includes two support rods 401, a sleeve 402, a fitting block 403 and a fitting groove 404. The sleeve 402 is sleeved outside the opposite ends of the two support rods 401. The fitting block 403 and the fitting groove 404 are respectively provided at the opposite ends of the two support rods 401, and the inner cavities of the fitting block 403 and the fitting groove 404 are fitted together.

[0031] As Figure 1 and Figure 4 shown in, the outer wall of the sleeve 402 is drivingly connected to an external hydraulic cylinder, so that when the hydraulic cylinder drives the sleeve 402 to move left and right, it can indirectly drive the movement of the control rod 306, and thus can provide convenience for the movement of the fixed rod 301. The two support rods 401 are respectively fixedly arranged at the ends of the control rod 306 at both ends of the fixed rod 301. The opposite ends of the two support rods 401 are movably inserted into the inner cavity of the sleeve 402. The length of the sleeve 402 is longer than the length of the inner cavity of the movable slot 307, so as to prevent the support rod 401 from being pulled out of the inner cavity of the sleeve 402 after the control rod 306 moves away. Through the fitting arrangement of the fitting block 403 and the fitting groove 404, when the opposite ends of the support rod 401 move towards each other, it can be more stable, and thus can strengthen the stability of the position of the control rod 306, and improve the effectiveness of restricting the rotation of the fixed rod 301.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
