Abstract
Description
Technical Field
[0001] This utility model relates to the field of paper box processing technology, specifically to a paper box forming mechanism and its forming device. Background Technology
[0002] In recent years, with the improvement of people's living standards, the requirements for the appearance quality of packaging products have also been increasing. High-end packaging boxes, such as mobile phone boxes, jewelry boxes, gift boxes, and cigarette boxes, generally consist of gray board and face paper. When processing packaging boxes, the gray board is usually made into a box blank first, and then the glued face paper is wrapped around the outer surface of the box blank. During packaging, the face paper needs to be edged, folded, folded in, and bubble-pressed to obtain the finished packaging box.
[0003] In existing cardboard box forming machines, processes such as edge folding, folding in, and bubble pressing are all driven by the same motor. During operation, three corresponding cams are set on the output shaft of the motor. The cams push the relevant parts back and forth to realize the corresponding process. Although this structural design can improve the continuity of the operation and reduce the overall size of the equipment, the bubble pressing cannot be controlled independently, which makes it difficult to control the pressure of the pressure plate during bubble pressing, resulting in poor bubble pressing effect. After the cardboard box is formed, a second bubble pressing machine is still required, which increases the production cost of enterprises. Summary of the Invention
[0004] This utility model addresses the deficiencies in existing technologies by providing a paper box forming mechanism and its forming device, which can improve the bubble pressing quality after folding, eliminate the need for secondary bubble pressing, and reduce enterprise production costs.

The second servo motor drives the second sliding component to move back and forth. The corner scraper is fixedly mounted at one end of the second sliding component. The pressure plate is fixedly mounted on the forming base. This invention, by directly fixing the pressure plate to the forming base and directly controlling the movement of the forming base via the first servo motor, allows the pressure plate, driven by the first servo motor, to press the folded paper against the side surface of the box blank after folding. This provides better control over the pressure applied, avoids the need for secondary pressure application, significantly reduces production costs, and improves the production efficiency of paper boxes.

On the same side of the forming base, from top to bottom, there are arranged a folding roller, a corner scraper, and a pressure plate.

[0044] like Figure 1-6As shown, this utility model also provides a paper box forming device, including a frame 10. The frame 10 is provided with two sets of opposing high-position forming mechanisms 100 and two sets of opposing low-position forming mechanisms 200. The two sets of high-position forming mechanisms 100 and the two sets of low-position forming mechanisms 200 are respectively located on the four sides of the paper box to be formed. Each high-position forming mechanism 100 and low-position forming mechanism 200 includes a forming base 20 slidably mounted on the frame 10 and a first servo motor 11 driving the forming base 20 to slide back and forth. On the same side of the forming base 20, from top to bottom... The forming base 20 is provided with a folding roller 21, a corner scraper 22, and a pressure plate 23 in sequence. The forming base 20 is provided with a first sliding component 30, a second sliding component 40, a folding cylinder 24, and a second servo motor 25.

[0045] In this utility model, the high-position forming mechanism 100 is provided with folding ear assemblies 50 on both sides. The folding ear assembly 50 includes a folding ear base 51, a folding ear cylinder 52 and a folding ear slide 53 driven by the folding ear cylinder 52 on the folding ear base 51, a folding ear scraper 54 on the folding ear slide 53, and a second slide rail 55 fixedly provided on the folding ear slide 53 to guide the folding ear slide 53. The second slide rail 55 is slidably connected to the folding ear base 51. The extension direction of the second slide rail 55 is the same as the movement direction of the first sliding assembly 30 and the second sliding assembly 40. The folding ear scraper 54 is located below the pressure plate 23 of the high-position forming mechanism 100 and above the folding roller 21 of the low-position forming mechanism 200.
[0046] Specifically, the high-position forming mechanism 100 has a third slide rail 27 fixedly mounted on its forming base 20, and the folded ear base 51 is slidably mounted on the third slide rail 27. The third slide rail 27 is perpendicular to the second slide rail 55 in the horizontal direction. The low-position forming mechanism 200 has a linkage bracket 60 on its forming base 20 that allows the folded ear base 51 to slide along the third slide rail 27. The linkage bracket 60 has a connecting rod 61. The folded ear base 51 has a buffer adjustment sleeve 56. The buffer adjustment sleeve has an oblong hole that penetrates its periphery. The connecting rod 61 penetrates the oblong hole. The buffer adjustment sleeve 56 has a first movable member (not shown), a second movable member (not shown), and a second elastic member (not shown) that makes the first movable member always tend to abut against the connecting rod 61. The first and second movable parts are respectively clamped on both sides of the connecting rod 61 in the circumferential direction. The end of the buffer adjusting sleeve 56 away from the folding lug base 51 is provided with a rotating sleeve 57 for controlling the movement of the second movable part. The rotating sleeve 57 is threadedly connected to the buffer adjusting sleeve. A push rod is provided inside the rotating sleeve 57, and the push rod abuts against the end of the second movable part away from the connecting rod 61. In actual use, the rotating sleeve 57 can be threadedly connected to the buffer adjusting sleeve, and the rotating sleeve 57 can be rotated, thereby moving the push rod away from or closer to the second movable part, thus adjusting the position of the folding lug base 51 on the third slide rail 27. This allows for adjustment of the distance of the folding lug scraper 54 according to the size of the cardboard box, improving the versatility of the equipment. Both the first and second movable parts have an arc-shaped positioning groove on their opposite sides that matches the connecting rod 61.
[0047] The working process of this utility model is as follows:
[0048] During operation, an external cardboard clamping device holds the box blank with the face paper attached and lowers it from above the frame 10, passing sequentially through the folding roller 21, corner scraper 22, pressure plate 23, and ear scraper 54 of the high-position forming mechanism 100. Before the box blank passes the folding roller 21, the folding cylinder 24 controls the folding roller 21 to move towards the box blank through the first sliding component 30, bringing the folding roller 21 close to the side of the box blank. During the descent of the box blank, the side of the face paper contacts the folding roller 21. The folding roller 21 folds the side of the face paper upwards and attaches it to the side of the box blank. When the upper edge of the box blank reaches the corner folding blade 22, the mold part of the carton clamping device first exits the box blank. Then, the second servo motor 25 moves the corner folding blade 22 towards the box blank through the second sliding component 40, and the corner folding blade 22 folds the upper edge of the face paper side of the face paper horizontally towards the inside of the box blank. After the corner folding blade 22 retracts and resets, the mold part of the carton clamping device re-enters the box blank. The upper edge of the horizontal fold is attached to the inside of the box blank, and the box blank continues to descend. When the box blank reaches the pressure plate 23, the first servo motor 11 drives the forming base 20 to move to one side of the box blank, and the pressure plate 23 presses against the side of the box blank to realize the bubble pressing process. When the box blank reaches the folding ear scraper 54, the folding ear cylinder 52 first drives the folding ear scraper 54 to move towards the box blank, and the folding ear scraper 54 folds the ear plates on the side of the face paper to the other two sides of the box blank, and then forms a low position. The first servo motor 11 of the forming mechanism 200 drives the forming base 20 to move towards the box blank, and pushes the folding ear base 51 towards the box blank through the linkage bracket 60. The folding ear base 51 drives the folding ear scraper 54 to attach the ear plate to the corresponding side of the box blank. Then, after the forming base 20 of the low-position forming mechanism 200 is reset, the box blank continues to descend under the control of the paper box clamping device, and completes the bonding of the face paper on the other two sides with the cooperation of the low-position forming mechanism 200, thereby obtaining the finished packaging box. The paper box clamping device adopts conventional technology in this field, and will not be described in detail here.
[0049] In summary, this invention directly fixes the pressure plate to the forming base and directly controls the movement of the forming base via a first servo motor. This allows the pressure plate, driven by the first servo motor, to press the folded face paper onto the side surface of the box blank after folding. This provides better control over the blister pressing force, avoiding the need for secondary blister pressing and eliminating the need for a separate blister press, significantly reducing production costs and improving the production efficiency of paper boxes. Furthermore, the first servo motor can also adjust the position of the forming base, adapting to the production of different paper boxes and improving the equipment's versatility.
[0050] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the actual technical aspects of the present utility model shall still fall within the scope of the technical solution of the present utility model.
