Technical Field

[0001] The utility model relates to the technical field of packaging boxes, in particular to a packaging box production device capable of preventing folding edges from rebounding. Background Art

[0002] As the name suggests, box packaging is a box used to package products. It can be classified by material, such as paper boxes, iron boxes, wooden boxes, cloth boxes, leather boxes, acrylic boxes, corrugated boxes, etc. The function of packaging boxes is to ensure the safety of products in transportation and improve the grade of products. With the rapid development of modern industry and the continuous improvement of people's living standards, people's demand for packaging boxes will continue to increase, and higher requirements are also placed on the quality of iron boxes. The increase in short-run workpieces, improving processing quality and reducing production costs are also market pressures and problems faced by paper box packaging companies. This requires the application of new technologies in the production process of iron box packaging, continuously improving the degree of automation of equipment, reducing equipment adjustment time and auxiliary preparation time of workpieces. Only by constantly adapting to new changes in the market and meeting the requirements of different users can the competitiveness of packaging box packaging companies be improved. Folding devices are needed in the production process of packaging boxes.

[0003] However, most of the existing packaging box folding devices do not have equipment to prevent the folding rebound. After the cardboard is folded, it will rebound, resulting in the need for the cardboard to be folded twice, which greatly reduces work efficiency. Therefore, in view of this, research and improvement are conducted on the shortcomings of the existing structure, and a packaging box production device that prevents folding rebound is proposed.

[0026] The sliding assembly 22 includes a connecting rod 221, and the two ends of the connecting rod 213 are rotatably connected to the connecting rod 221. The end of the connecting rod 221 away from the connecting rod 213 is rotatably provided with a slide plate 222. The top of the slide plate 222 is fixedly connected to the connecting block 223, and the top of the connecting block 223 is fixedly connected to the clamp 224. The top of the workbench 1 is fitted with a limiting plate 225.

[0027] Furthermore, the slide plate 222 forms a sliding structure with the workbench 1 through the connecting rod 221 and the connecting rod 213. During operation, when the rotating rod 212 rotates, it drives the connecting rod 213 to rotate, pushes the connecting rod 221 to swing, and pulls the slide plate 222 to slide along the inner wall of the workbench 1, driving the two sets of connecting blocks 223 and the clamp 224 to slide in the same direction to clamp and fix the limit plate 225.

[0028] Furthermore, the center of the rotating rod 212 and the center of the connecting rod 213 are on the same straight line. During operation, by setting the center of the rotating rod 212 and the center of the connecting rod 213 to be on the same straight line, when the rotating rod 212 rotates, it drives the connecting rod 213 to rotate, pushing the connecting rod 221 to swing.

[0029] Furthermore, two groups of connecting rods 221 are provided, and the two groups of connecting rods 221 are distributed parallel to the center of the rotating rod 212. During operation, by setting two groups of connecting rods 221, the slide plate 222 is pulled to slide along the inner wall of the workbench 1, driving the two groups of connecting blocks 223 and the clamps 224 to slide in the same direction to clamp and fix the limit plate 225.

[0030] Example 2: Figure 1 - Figure 5As shown, the top of the workbench 1 is fixedly connected to a bracket 3, the bottom end of the bracket 3 is fixedly connected to an electric hydraulic rod 31, the bottom end of the electric hydraulic rod 31 is fixedly connected to a connecting plate 32, the bottom end of the connecting plate 32 is fixedly connected to a fixed block 33, the interior of the connecting plate 32 is penetrated by a positive and negative threaded rod 34, the outer wall of the positive and negative threaded rod 34 is threadedly connected to a slider 35 that is slidably connected to the inner wall of the connecting plate 32, the bottom end of the slider 35 is fixedly connected to a movable block 36, the side wall of the movable block 36 is fixedly connected to a clamping block 37, the bottom end of the fixed block 33 is clamped and connected to a connecting plate 38, the bottom end of the connecting plate 38 is fixedly connected to a pressing plate 39, the bottom end of the workbench 1 is fixedly connected to a supporting foot 310, and one end of the positive and negative threaded rod 34 is fixedly connected to a handwheel 311 When the locking block 37 is moved away from the fixing block 33 and the connecting plate 38, the pressing plate 39 is removed, and then the replaced pressing plate 39 and the connecting plate 38 are brought close to the fixing block 33, and the above steps are performed in the reverse direction to lock the locking block 37 into the locking groove of the side wall of the fixing block 33 and the connecting plate 38, thereby achieving the purpose of facilitating the replacement of the pressing plate 39.

[0031] Furthermore, the slider 35 forms a sliding structure with the connecting plate 32 through the forward and reverse threaded rods 34. When working, turning the handwheel 311 drives the forward and reverse threaded rods 34 to rotate, pushing the two groups of sliders 35 to slide relative to each other along the sliding groove at the bottom end of the connecting plate 32.

[0032] Furthermore, the side walls of the fixed block 33 and the connecting plate 38 are provided with slots that fit with the outer walls of the card block 37. During operation, by providing slots that fit with the outer walls of the card block 37 on the side walls of the fixed block 33 and the connecting plate 38, when the card block 37 is away from the fixed block 33 and the connecting plate 38, the pressure plate 39 is removed, and then the replaced pressure plate 39 and the connecting plate 38 are placed close to the fixed block 33, and the above steps are performed in the reverse direction to insert the card block 37 into the slots on the side walls of the fixed block 33 and the connecting plate 38, so as to facilitate the replacement of the pressure plate 39.

[0033] Working principle: When using the packaging box production device to prevent folding edge rebound, first, the limit plate 225 is placed on the workbench 1, and then the servo motor 211 is started to drive the rotating rod 212 to rotate. By setting the center of the rotating rod 212 and the center of the connecting rod 213 to be on the same straight line, when the rotating rod 212 rotates, it drives the connecting rod 213 to rotate, pushing the connecting rod 221 to swing, and by setting two sets of connecting rods 221, the slide plate 222 is pulled to slide along the inner wall of the workbench 1, driving the two sets of connecting blocks 223 and the clamp 224 to slide in the same direction to clamp and fix the limit plate 225, and then the cardboard is placed on the top of the limit plate 225, and the electric hydraulic rod 31 is started to drive the pressure plate 39 to move downward through the connecting plate 32 and the connecting plate 38 to squeeze the cardboard to make its folding edge more complete. After folding the plastic packaging box, the above steps are performed in the opposite direction to remove the limit plate 225. By setting the limit plate 225, the folding edge rebound of the cardboard packaging box is avoided.

[0034] When the limit plate 225 is replaced, the pressure plate 39 that matches the limit plate 225 needs to be replaced at the same time. At this time, it is necessary to turn the hand wheel 311 to drive the forward and reverse threaded rods 34 to rotate, pushing the two sets of sliders 35 to slide relative to each other along the sliding grooves at the bottom ends of the connecting plates 32, so that the movable block 36 and the clamping block 37 slide in the same direction. By providing the side walls of the fixed block 33 and the connecting plate 38 with the clamping grooves that fit with the outer walls of the clamping block 37, when the clamping block 37 is away from the fixed block 33 and the connecting plate 38, the pressure plate 39 is removed, and then the replaced pressure plate 39 and the connecting plate 38 are placed close to the fixed block 33, and the above steps are performed in the reverse direction to clamp the clamping block 37 into the clamping grooves on the side walls of the fixed block 33 and the connecting plate 38, thereby achieving the purpose of facilitating the replacement of the pressure plate 39.
