Description

Technical Field

[0001] This utility model belongs to the field of paper product processing, specifically, it relates to a pressing device for paper product processing. Background Technology

[0002] Existing paper packaging technology has a wide range of applications, with various types of paper packaging used in all aspects of human life and production. Currently, when processing paper products, workers need to press multiple sheets of cardboard together and use a pressing device to heat-press them, so that the cardboard is bonded and fixed together, thus completing the pressing work.

[0003] Chinese Patent No. CN211868784U discloses a pressing device for paper product processing, including a support base and a worktable. The worktable is fixedly connected to the upper surface of the support base, and support columns are fixedly connected to both sides of the worktable. The surface of the support columns is provided with sliding grooves. A placement component is provided in the middle of the upper surface of the worktable, and a placement seat is fixedly connected to the upper end of the support columns. A support frame is fixedly connected to the upper surface of the placement seat. With the use of the placement component, not only can the paper to be pressed be clamped, but it can also absorb the odor generated by the paper during the pressing process, avoiding the impact of odor on the workers and protecting them to a certain extent. With the use of the pressing component, the setting of the buffer component and the clamping seat can reduce the vibration generated during the pressing process.

[0004] In the aforementioned comparative documents, when paper products are pressed, workers need to manually operate the clamping seat to fix the paper products. After the paper products are pressed, the clamping seat needs to be operated again to remove them before the loading operation can be carried out, which reduces the efficiency of the paper product pressing process.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a pressing device for paper product processing.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0009] The fixed assembly includes a movable frame that slides on both sides, a clamping plate that slides on the movable frame, a first rack block that slides on the bottom of the placement plate, and a rotating shaft that rotates in the worktable. The rotating shaft cooperates with the first rack block and the movable frames on both sides. A slide rod is slidably fitted in the worktable. The slide rod cooperates with the rotating shaft, and the placement plate cooperates with the slide rod.

[0010] Optionally, the worktable has a concave groove, a first placement groove on one side of the worktable, a second placement groove and a third placement groove on one side of the first placement groove, a through groove on one side of the third placement groove, a sliding rod slidingly engaged in the through groove, first sliding grooves on opposite sides of the placement grooves, first sliders on opposite sides of the placement plate, the first sliders slidingly engaged in the first sliding grooves, a connecting groove on one side of the concave groove, a rotating shaft rotatingly engaged in the connecting groove, a spring at the bottom of the rotating shaft, and the other end of the spring being engaged at the bottom of the connecting groove; by the first sliders on both sides of the placement plate slidingly engaged in the first sliding grooves, the stability of the placement plate during sliding is ensured, and the spring at the bottom of the rotating shaft causes the rotating shaft to rotate in the opposite direction to reset after rotation.

[0011] Optionally, a second rack block is installed on one side of the movable frame, a damping rod is provided on one side of the second rack block, a first gear is installed on one side of the rotating shaft, the second rack blocks on both sides are located on both sides of the first gear and mesh with it, a second gear is installed on the first gear, the first rack block meshes with the second gear, a ratchet is installed on the second gear, a locking block is installed on one side of the slide rod, the locking block meshes with the teeth of the ratchet, a first spring is sleeved on the slide rod, the other side of the first spring is installed on one side of the third placement groove, an abutment block is installed at one end of the slide rod, a second sliding groove is opened at the bottom of the placement plate, a second slider is installed on one side of the first rack block, the second slider slides in the second sliding groove, a second spring is installed on one side of the second slider, and an operating rod is installed on one side of the first rack block.

[0012] Optionally, a square groove is installed on one side of the movable frame, and a square block is installed on one side of the clamping plate.

[0013] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art. Of course, any product implementing this utility model does not necessarily need to achieve all of the following advantages at the same time:

[0014] When this paper product processing pressing device is in use, the first rack block meshes with the second gear through the force of the second spring. By pulling the placement plate, the first rack block slides, thereby driving the second gear to rotate. The rotation of the second gear drives the first gear and the ratchet gear to rotate simultaneously. The rotation of the first gear drives the moving frames on both sides of the second rack block to move to the sides, releasing the clamping effect of the clamping plates on the paper product. At this time, the locking block meshes with the teeth of the ratchet gear to engage, and the spring at the bottom of the rotating shaft is in a wound state. When pressing the paper product again, by moving the operating lever, the first rack block moves to one side away from the second gear. After pushing the placement plate to a certain position, it will push the abutment block to move the sliding rod backward, so that the locking block moves away from the ratchet gear. The first gear rotates in the opposite direction through the force of the spring, driving the clamping plates on both sides of the moving frames to clamp the paper product. By setting a damping rod on one side of the second rack block, the clamping plates on both sides will slowly slide to clamp.
