Description

Technical Field

[0001] The utility model relates to the technical field of carton production, in particular to a folding device for producing paper packaging boxes. Background Art

[0002] A folding device for paper packaging production is a device used to fold the cardboard material during the production of paper packaging boxes. This device folds the cardboard to form the corners of the box, completing the assembly of the box. The folding device plays a vital role in the production of paper packaging boxes, improving production efficiency, reducing production costs, and ensuring the quality and stability of the boxes.

[0003] Common folding devices for producing paper packaging boxes include single-side folding machines, double-side folding machines, corner folding machines, and manual folding machines. The existing single-side folding machines and double-side folding machines adopt different folding methods according to different production methods. For example, the cylinder press-type folding method is to perform a single folding on a single paper packaging box by controlling the mold through a cylinder. This production and processing efficiency is low. If the folding method is used on a conveyor belt, although this is more efficient than the cylinder press-type method, its working principle requires a folding mechanism to be set at the edge of the conveyor belt. The folding mechanism needs to be completed by combining the two actions of rising and pushing to realize the folding of the edge of the paper packaging box. These two actions require the folding mechanism to be completed in stages, one before and one after, and cannot be performed at the same time, which makes the folding mechanism less efficient than ideal. It also causes the structural composition of the folding mechanism to be more concentrated and complex, which is not convenient for later maintenance.

[0004] Therefore, it is necessary to invent a paper packaging box production folding device to solve the above problems. Utility Model Content

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] The utility model provides Figure 1-5 The device for producing and folding paper packaging boxes shown in the figure includes two frames 1. The frames 1 serve as the foundation of the entire device and provide support for a conveyor belt 2 and other components. The frames 1 can be designed into different sizes and shapes according to actual production needs. A conveyor belt 2 is provided above and between the two frames 1. The conveyor belt 2 is used to carry and transport paper packaging boxes to achieve continuous production. Two sets of support frames 6 are provided above the two frames 1. A turning mechanism 3 is provided on both sides of the conveyor belt 2 and between the two sets of support frames 6.

[0027] The turning mechanism 3 includes:

[0028] The folding plate 33 is provided on one side of the conveyor belt 2. The folding plate 33 is L-shaped, and the upper surface of one side of the folding plate 33 is parallel to the upper surface of one side of the conveyor belt 2.

[0029] At least two cylinders 31 are respectively arranged at the two ends of the back side of the folding plate 33. A connecting seat 32 is fixedly installed at both ends of the back side of the folding plate 33. The output end of the cylinder 31 is rotatably connected to the connecting seat 32 at the corresponding position. The L-shaped folding plate 33 is used to fold the edge of the paper packaging box. The material of the folding plate 33 can be wear-resistant and pressure-resistant material, and the cylinder 31 is used to drive the movement of the folding plate 33 to realize the folding function of the paper packaging box. At the same time, the number and size of the cylinder 31, as well as the size of the folding plate 33 can be adjusted according to production requirements.

[0030] Furthermore, in the above technical solution, a No. 1 mounting frame 4 is fixedly installed above one end of the two racks 1, and a No. 2 mounting frame 5 is fixedly installed above the other end of the two racks 1. Two sets of support frames 6 are arranged between the No. 1 mounting frame 4 and the No. 2 mounting frame 5. The No. 1 mounting frame 4 and the No. 2 mounting frame 5 are used to fix and support other components.

[0031] Furthermore, in the above technical solution, a groove 11 is provided on the inner side of the frame 1, and the number and position of the grooves 11 correspond to the number and position of the cylinders 31. The tail end of the cylinder 31 is located in the groove 11, and the tail end of the cylinder 31 is rotatably connected to the inner wall of the groove 11. The cylinder 31 is installed in an inclined shape. Since the cylinder 31 is installed at an inclined position, a groove 11 needs to be provided on the inner wall of the frame 1 to facilitate the installation of the cylinder 31 and avoid interference with the movement of the cylinder 31.

[0032] Furthermore, in the above technical solution, cross frames 61 are provided on both sides above the conveyor belt 2, and the two ends of the cross frame 61 are connected to the top of the two groups of support frames 6.

The position of the brush 81 corresponds to the edge of the conveyor belt 2. By filling glue in the storage box 8, the glue in the storage box 8 is evenly applied to the edge of the paper packaging box by the brush 81.

[0035] The utility model provides a paper packaging box production folding device. When in use, its working process is as follows:

[0036] First, place the two frames 1 and install the conveyor belt 2. Then, set up two sets of support frames 6 on both sides of the conveyor belt 2, install the turnover mechanism 3, and adjust the position of the folding plate 33 so that it is parallel to the upper surface of one side of the conveyor belt 2. At the same time, ensure that the number and position of the cylinders 31 are correct, and install the electric push rods 62 and pressure plates 63 and other structures on the two sets of support frames 6. Finally, according to the size of the paper packaging box to be folded, adjust the position of the pressure roller 7 on the first mounting frame 4 and the position of the storage box 8 on the second mounting frame 5, and fill the storage box 8 with an appropriate amount of glue.

[0037] Then, multiple paper packaging boxes are conveyed one by one from one end of the conveyor belt 2 equipped with a storage box 8. When a single paper packaging box is conveyed from one end of the conveyor belt 2 to the bottom of the two groups of support frames 6, the electric push rod 62 controls the pressure plate 63 to descend, and covers the paper packaging box at that position to prevent it from moving. Then, the two groups of flipping mechanisms 3 are immediately started, that is, the cylinder 31 controls the flipping of the folding plate 33, and the folding plate 33 flips upward from the bottom of one side of the paper packaging box, thereby flipping and folding one side of the paper packaging box. After that, the folding plate 33 controlled by the cylinder 31 is immediately reset, thereby quickly completing the folding of the edge of the paper packaging box.

[0038] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
