Abstract
Description
Technical Field
[0001] This utility model relates to the field of paper product manufacturing technology, and more specifically, to a paper product edge folding and forming mechanism. Background Technology
[0002] Cardboard boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc., and they come in various specifications and models. Cardboard boxes commonly have three or five layers, while seven-layer boxes are less common. Each layer consists of linerboard, corrugated paper, core paper, and face paper. Linerboard and face paper can be made of kraft paper or kraft paper, while the core paper is made of corrugated paper. The colors and textures of different types of paper are different, and the paper produced by different manufacturers also varies in color and texture.
[0003] When cardboard boxes are produced, the edges need to be folded to facilitate the merging and fixing of the boxes and improve the stability of the support connections. However, because the distance between the edges of the cardboard boxes is small, they are prone to tilting when folded manually, which affects the folding quality and increases the workload of the workers. Therefore, it is necessary to provide a precise folding and forming mechanism for the edges of paper products to solve the above problems. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a paper product edge precision folding and forming mechanism, which realizes the folding of the paperboard edge through the folding component, reducing the error caused by manual folding.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a paper product edge precision folding and forming mechanism, including an L-shaped processing table, wherein a positioning component is provided on one side of the top of the L-shaped processing table, and a folding component is provided on the side of the positioning component;
[0006] The positioning component includes a support frame, in the middle of which a positioning cylinder and a piston rod are arranged, and at the bottom of the piston rod are a mounting plate and a positioning plate.

A docking block and a folding plate are disposed on the side of the mounting block, and a rotating rod and a protrusion are disposed in the middle of the docking block. A driven bevel gear and a driving bevel gear are disposed at one end of the rotating rod.
[0008] Furthermore, the bottom of the support frame is bolted to one side of the top of the L-shaped processing table, and a positioning cylinder is bolted to the middle of the support frame. There are two positioning cylinders, which are symmetrically distributed at both ends of the top of the support frame. The movable end of the positioning cylinder is equipped with a piston rod, and the piston rod is correspondingly set with the positioning cylinder.

The side of the support frame is provided with a groove, and the groove runs through both sides of the support frame.
[0010] Furthermore, the connecting top plate is fixedly connected to the top of the support frame, and the connecting top plate is located on the side of the support frame away from the L-shaped processing table. Two cylinders are bolted to the middle of the connecting top plate, and mounting plates are installed on the movable ends of the cylinders. The side of the mounting plate contacts the side of the support frame near the connecting top plate, and a mounting block is fixedly connected to the bottom of the mounting plate near the support frame.
[0011] Furthermore, there are two mounting blocks, symmetrically distributed at both ends of the side of the mounting plate, and a docking block is provided between the two mounting blocks.

[0026] like Figure 1 , Figure 2 , Figure 3 As shown, the specific implementation method is as follows: the positioning component 2 includes a support frame 8, a positioning cylinder 3 and a piston rod 4 are arranged in the middle of the support frame 8, and a mounting plate 5 and a positioning plate 6 are arranged at the bottom of the piston rod 4. The bottom of the support frame 8 is bolted to one side of the top of the L-shaped processing table 1, and the positioning cylinder 3 is bolted to the middle of the support frame 8. There are two positioning cylinders 3, which are symmetrically distributed at both ends of the top of the support frame 8.

[0030] After the positioning plate 6 clamps and positions the cardboard, the cylinder 11 drives the mounting plate 12 and the folding plate 15 to descend, so that the bottom of the folding plate 15 contacts the edge to be folded. Then, the drive motor 19 drives the active bevel gear 20 to rotate. The active bevel gear 20 and the driven bevel gear 21 mesh with each other, so that the active bevel gear 20 drives the driven bevel gear 21 and the rotating rod 16 to rotate at a constant speed.
