By rotating the threaded rod to adjust the distance between the two limiting plates, the hydraulic cylinder drives the push plate to push the carton forward, thereby limiting the carton, ensuring the moving route of each subsequent carton, ensuring the consistency of the indentation, and ensuring the carton indentation effect.

[0004] Although the above patents can solve the corresponding technical problems, they still have certain defects:

[0005] When the position between the two push plates needs to be adjusted to limit the cardboard, the operator needs to frequently twist the two threaded rods respectively, and the operation process is relatively cumbersome. Utility Model Content

[0006] The utility model aims to address the defects and shortcomings of the prior art and to provide a carton creasing device which can realize the movement of the push plate without frequent twisting of the hands and has a relatively simple operation process.

[0007] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a carton creasing device, comprising a workbench, two rectangular blocks symmetrically arranged on the workbench, characterized in that it also includes square perforations respectively opened on the two rectangular blocks, rectangular slide bars which can be slidably arranged on the rectangular blocks and located in the square perforations, a push plate arranged on the side end surface of the rectangular slide bar, a plurality of circular hole slots opened on the upper end surface of the rectangular slide bar, lifting openings respectively opened on the two rectangular blocks and connected to the square perforations, A lifting cylinder which can be lifted and lowered on the rectangular block and is located in the lifting opening, a cylindrical block which is arranged at the lower end of the lifting cylinder and is gap-matched with the circular hole slot, and a prompting device which is respectively arranged between the two rectangular blocks and the lower end surface of the rectangular slide bar and is used for prompting when the positions of the cylindrical block and the circular hole slot correspond. The upper end of the lifting cylinder passes through the lifting opening and is located above the rectangular block. The lifting opening is perpendicular to the square through-hole, and a plurality of circular hole slots are equidistantly arranged along the length direction of the rectangular slide bar.

[0008] A further improvement is that two extension plates are symmetrically arranged at the upper end of the lifting cylinder to facilitate the hand to pull the lifting cylinder up, the two extension plates are vertically arranged on the lifting cylinder, and two limit columns are arranged on the upper end surfaces of the two rectangular blocks on both sides of the lifting cylinder.

[0009] A further improvement is that: the upper end surfaces of the two limit columns are provided with limit slots for engaging with the extension plate.

[0010] A further improvement is that a counterweight block is arranged inside the lifting cylinder.

[0011] Further improvements are: the prompt device includes a plurality of prompt card slots opened at the lower end of the rectangular slide bar and connected to the square perforation, a sliding slot opened on the two rectangular blocks and connected to the square perforation, a prompt card block which can be lifted and lowered on the rectangular block and located in the sliding slot, a compression spring which is arranged between the lower end of the prompt card block and the rectangular block and located in the sliding slot, the upper end surface of the prompt card block is a conical surface, and the plurality of prompt card slots are arranged equidistantly along the length direction of the rectangular slide bar.

[0012] A further improvement is that a collision layer is provided at the lower end of the rectangular slide bar, a plurality of the prompt card slots are opened on the collision layer, the collision layer is a metal layer or a ceramic layer, and the prompt card block is a metal block or a ceramic block.

[0013] After adopting the above technical scheme, the beneficial effect of the utility model is as follows: when it is necessary to adjust the position between the two push plates to limit the cardboard, the lifting cylinder is pulled upward by hand to make the cylindrical block lose the match with the circular hole slot. At this time, the rectangular slide bar can be pushed in the square perforation to drive the push plate to move horizontally. The movement of the push plate can be achieved without frequent twisting of the hand, and the operation process is relatively simple.

[0014] Further effect: during the lateral movement of the rectangular slide bar in the square perforation, if the positions of the cylindrical card block and the circular hole card slot correspond, the positions of the prompt card slot and the sliding slot also correspond. At this time, the compression spring pushes the prompt card block to rise in the sliding slot and engage with the prompt card slot, thereby forming a slight lateral sliding resistance to the rectangular slide bar, thereby reminding the operator that the positions of the prompt card slot and the sliding slot have corresponded, and the operator can judge the lateral sliding distance of the rectangular slide bar according to the number of resistances formed, so that the moving distance between the two push plates is the same, so that the cardboard is kept in the middle of the workbench.

[0015] Further effect: when the prompt card block cooperates with the prompt card slot and pushes the rectangular slide bar to move horizontally, the prompt card slot cooperates with the conical surface of the prompt card block to push the prompt card block down in the sliding slot, and forms an intermittent cooperation phenomenon through cooperation with the compression spring.

[0016] Further effect: when the extension plate abuts against the limiting column, the extension plate is clamped by the limiting clamping groove, which can prevent the extension plate from moving left and right on the limiting column, thereby improving the limiting effect of the limiting column on the extension plate.

[0017] Further effect: when it is necessary to release the fixation of the rectangular slide bar on the rectangular block, the two extension plates are held by hands and pulled upwards of the rectangular block so that the position of the extension plates is higher than the height of the two limit columns, thereby driving the lifting cylinder to rise in the lifting opening, and the cylindrical clamping block and the circular hole clamping slot are disengaged. At this time, the lifting cylinder is rotated again so that the two extension plates are respectively located above the two limit columns, and the hand grip on the two extension plates is removed to make them abut against the upper end surfaces of the limit columns. There is no need to keep the hand driving the lifting cylinder to control the position of the rectangular slide bar in the square perforation, thereby controlling the position of the push plate on the workbench.

[0018] Further effect: when the compression spring pushes the prompt card block to engage with the prompt card slot, the prompt card block collides with the collision layer to produce a sound, thereby playing a prompt role, which can make it more convenient for operators to judge the lateral sliding distance of the rectangular slide bar according to the collision sound.

[0019] Further effect: when the hand removes the pull on the lifting cylinder, the counterweight block can allow the lifting cylinder to naturally drop in the lifting opening, so that the cylindrical clamping block and the circular hole clamping groove are automatically engaged, and when the extension plate abuts against the limit column, the pressure of the extension plate on the limit column is increased, reducing the sliding phenomenon of the extension plate on the upper end surface of the limit column.
