Edge-folding and corner-laminating machine for cartons

Abstract

The invention belongs to the technical field of corner-laminating machines, and specifically discloses an edge-folding and corner-laminating machine for cartons. The edge-folding and corner-laminatingmachine comprises a base, a supporting plate, a connecting plate, an electric pushing rod, a mounting base, a pressure plate, a threaded rod, a threaded tube, an arc-shaped block, edge-folding blocks, an edge-folding slot, a fixed arm, a movable arm, a side plate, a corner-laminating sheet, a screw, a threaded hole, a laminating sheet, a first rotary shaft, a hydraulic rod, a fixed disc, a movable disc, a movable block, a second rotary shaft and a connecting rod. According to the edge-folding and corner-laminating machine for the cartons disclosed by the invention, a paper board is placed onthe top of the edge-folding slot inside the base, so that the centre of the edge-folding slot and the centre of the paperboard are coaxial; the electric pushing rod is switched on by an external control switch, and the threaded rod is rotated, so that the threaded rod rotates in the threaded tube, and the arc-shaped block at one end of the threaded rod drives the edge-folding blocks to move on thetop of the pressure plate; and the positions of the four edge-folding blocks are regulated, and the electric pushing rod drives the edge-folding blocks at the periphery of the pressure plate to pressto the paper board, so that the paper board is pressed into the edge-folding slot, and therefore, edge-folding of the paper board is accomplished, and corner-laminating for cartons of different sizesis adapted.

Description

technical field [0001] The invention belongs to the technical field of corner sticking machines, in particular to a carton edge folding and corner sticking machine. Background technique [0002] Paper product packaging is the most used type of packaging industrial products. Cartons are the most important form of transportation packaging, and cartons are widely used as sales packaging for various products such as food, medicine, and electronics. With the changes in transportation methods and With the change of sales methods, the styles of cartons and cartons are becoming more and more diversified. Almost every new type of non-standard cartons comes out with a set of automation equipment, and the cartons themselves with novel shapes have also become a means of product promotion. . [0003] At present, with the large increase in the amount of product packaging, especially the improvement of the quality requirements for the cover of the product packaging box, the original all-h...

Problems solved by technology

[0003] At present, with the large increase in the amount of product packaging, especially the improvement of the quality requirements for the cover of the product packaging box, the original all-handmade production can no longer meet the product's demand for the packaging quantity. The existing cartons are generally folded and pasted. This will increase the manufacturing cost of the carton. The general carton folding and pasting machine has a complex structure, a large size, and is not easy to use, and the existing corner pasting machines generally can only paste corners on a single carton corner, which will The production efficiency of the carton is greatly reduced, and the size of the general carton is not easy, and it is not easy to fold the corners
