Description
Technical Field
[0001] This utility model relates to the technical field of corrugated cardboard box folding machines, specifically a folding machine for cardboard box processing. Background Technology
[0002] A folding machine for corrugated cardboard box processing is a device specifically designed to automatically bend, crimp, and preliminarily shape die-cut corrugated cardboard.
[0003] A search revealed a Chinese patent for a cardboard box folding machine, publication number CN 211105912 U. This device can replace manual folding of cardboard boxes, saving time and effort and improving work efficiency. It includes a fixed frame, a moving beam, a second cylinder, a cardboard box to be folded, and a third cylinder. Support columns are installed at the four corners of the bottom of the fixed frame, with the top of each support column connected to the bottom of the fixed frame and the bottom of the support column in contact with the ground. A longitudinal slide is provided in the middle of the two sets of support columns. The third cylinder is connected to an air pump, and by controlling the air pump, the third cylinder can perform telescopic movement. A push block is installed at the front end of the third cylinder, and the rear end of the push block is connected to the front end of the third cylinder. A fourth cylinder is installed at the front end of the slide, with the rear end of the fourth cylinder connected to the front end of the slide. The fourth cylinder is connected to an air pump, and by controlling the air pump, the fourth cylinder can perform telescopic movement. A push block is installed at the front end of the fourth cylinder, and the rear end of the push block is connected to the front end of the fourth cylinder.
[0004] Existing carton folding machines place the die-cut cardboard on a worktable, and a pressure plate at the top presses down, pushing the bottom of the box downwards. Limiting plates installed at both ends of the worktable and on the lower support plate push up and fold the four sides of the box bottom, before moving it to the next process via a slide at the bottom of the support plate. However, the support plate in existing carton folding machines is only located in the middle of the box bottom, failing to provide effective support for the four sides. This results in a lack of rigid support on the four sides of the cardboard when the pressure plate presses down, making it prone to deformation or bending. Therefore, a folding machine for carton processing is needed to solve the above problems. Utility Model Content
