Description

Technical Field

[0001] The present application relates to the technical field of packaging equipment, and more specifically, to an outer packaging paper folding device. Background Art

[0002] Paper packaging boxes are the most widely used outer packaging products and are also an indispensable part of modern logistics. They bear the important responsibilities of containing, protecting products and being beautiful. Before folding the existing paper outer packaging, it is often necessary to press creases on the original cardboard, and then the creases need to be folded by a folding machine to make it a three-dimensional complete outer packaging carton. However, during the folding process, the folding machine cannot shape the cardboard, which may cause the cardboard to shift during folding, making the cardboard scrapped and unusable.

[0003] Paper folding machines improved to address the above-mentioned problems include a folding machine for packaging box production proposed in Chinese patent number CN213733678U, which rotates a motor to drive a rotating shaft and a screw to rotate, and the screw drives the threaded block to move toward the middle of the movable plate. At the same time, the movable plate is rotated ninety degrees through the hinge by extending and shortening the multi-section telescopic rod, thereby realizing folding the cardboard. The hydraulic rod is extended to drive the pressing block to move downward, so that the cardboard can be pressed and fixed to prevent the cardboard from shifting when the device is working. At the same time, the bottom of the cardboard can also be shaped to prevent the crease of the cardboard from being non-standard when folding.

[0004] When the above-mentioned paper folding machine is performing a folding operation, the semi-finished cardboard is placed on the base, and the folding operation is performed through the vertical base and the movable plate. However, the base and the movable plate of the above-mentioned paper folding machine are fixed in size, and can only perform folding operations of one size, and the folding distance cannot be adjusted according to different requirements. In view of this, we propose an outer packaging paper folding device. Utility Model Content

The paper folding component 3 for folding the paperboard is placed in the middle of the inner side of the paper folding machine body 1, as shown in FIG. Figure 2 As shown, the origami component 3 is composed of two symmetrically arranged bases 31, a movable plate 32, a telescopic structure 33 and a connecting rod 34, and the two symmetrically arranged bases 31 are connected by the telescopic structure 33;

[0029] like Figure 2 and Figure 3 As shown, the telescopic structure 33 is composed of a telescopic plate 331, a movable rod 332, a fixed slider 333 and a limit plate 334. The telescopic plate 331 is arranged in the middle and is fixedly connected to the middle of the two bases 31 respectively. The extending members composed of the movable rod 332, the fixed slider 333 and the limit plate 334 are respectively arranged one above and one below the telescopic plate 331. Figure 4 As shown, each extension member is provided with four movable rods 332, and both ends of each movable rod 332 are rotatably connected to the block, wherein the block at one end is fixedly connected to the side of the base 31, and the block at the other end is fixedly connected to the fixed slider 333, and the fixed slider 333 is sleeved on the outside of the limiting plate 334, and the fixed slider 333 can slide on the outside of the limiting plate 334, and both ends of the limiting plate 334 are fixedly connected to the inner side of the folding machine body 1, and can play a role in stabilizing the structure while the fixed slider 333 slides.

[0030] like Figure 2 and Figure 3 As shown, the middle parts of the bottom ends of the two bases 31 are fixedly connected with fixed bottom blocks 35, and the middle parts of the two fixed bottom blocks 35 are threadedly connected with guide rods 36. The guide rod 36 consists of a screw and a bevel gear. The screw part is threadedly connected to the fixed bottom block 35, and one end of the screw is fixedly connected with a bevel gear.
