Description

Technical Field

[0001] This application relates to the field of paper packaging box processing technology, specifically a pressing device for paper packaging box processing. Background Technology

[0002] Paper packaging boxes are containers made primarily of paper or cardboard through processing, folding, gluing, or molding techniques. They are used to hold, protect, transport, or display goods. They are one of the most widely used packaging forms in the modern packaging industry, and due to their environmental friendliness, processability, and cost-effectiveness, they have important applications in many fields such as food, daily necessities, electronic products, and pharmaceuticals.

[0003] Currently, in the process of processing and pressing paper packaging boxes, the packaging box is generally pressed in one go, that is, pressure is applied to the entire packaging box at once. The stress distribution of this pressing method may be uneven, especially at the edges, creases or weak points of the packaging box, where stress concentration is likely to occur. In addition, when the surface of the packaging box is uneven, some areas (such as corners) may not be fully compressed, forming tiny gaps and affecting the processing quality. Utility Model Content

[0004] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and to propose a pressing device for processing paper packaging boxes, so as to solve the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides a pressing device for processing paper packaging boxes, including a base, a processing groove on the top of the base, a vertical plate fixedly connected to the top of the base, a plate shaft fixedly connected to the top of the vertical plate, a rotating arm rotatably connected to the outer surface of the plate shaft, a connecting rod fixedly connected to one end of the rotating arm, a buffer cylinder fixedly connected to the bottom end of the connecting rod, a spring installed inside the buffer cylinder, a T-shaped rod slidably connected to the inner wall of the buffer cylinder, a lower pressure plate installed at the bottom of the T-shaped rod, and an alternating eccentric motion mechanism installed on the base.

[0006] Preferably, the alternating eccentric motion mechanism includes a motor fixedly installed inside the base, the output end of the motor is fixedly connected to a drive shaft, and a drive gear is fixedly sleeved on the outer surface of the drive shaft. The alternating eccentric motion mechanism can drive two sets of rotating arms to swing sequentially, thereby driving two sets of lower pressure plates to press down alternately.

[0007] Preferably, a lower drive shaft is rotatably connected to the outer surface of the base, and a transmission gear is fixedly sleeved on the outer surface of the lower drive shaft, with the outer surface of the transmission gear meshing with the outer surface of the drive gear.

[0008] Preferably, an eccentric wheel is fixedly sleeved on the outer surface of the lower moving shaft, and an upper fixed shaft is fixedly connected to the outer surface of the base.

[0009] Preferably, a first swing arm is rotatably connected to the outer surface of the upper fixed shaft, and a second swing arm is rotatably connected to the outer surface of the upper fixed shaft.

[0010] Preferably, both the first and second swing arms are provided with guide rods at their tops, and a counterweight ball is movably mounted on the end of the swing arm away from the connecting rod, with the outer surface of the counterweight ball fixedly connected to the top of the guide rod.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. The pressing device for paper packaging box processing uses an alternating eccentric motion mechanism during the pressing process to allow two sets of lower pressure plates to act on only a local area of ​​the packaging box each time. This disperses the pressure that was originally concentrated in a large area to multiple small areas, applying it in stages. In this way, the stress distribution is more dispersed, effectively reducing the risk of single-point overload, lowering the possibility of damage to the packaging box structure due to stress concentration, and ensuring the integrity and stability of the packaging box.

[0012] 2. This paper packaging box processing clamping device uses two sets of lower pressure plates to alternately move downwards to clamp the box. It can flexibly adjust the clamping sequence and location according to the different shapes and sizes of the packaging boxes. For irregularly shaped packaging boxes, the clamping sequence of the lower pressure plates can be reasonably arranged to ensure that each part receives appropriate pressure, adapting to diverse needs and improving the versatility of the equipment.

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] Please see Figure 1-4 A pressing device for processing paper packaging boxes includes a base 1, a processing groove 2 on the top of the base 1, a vertical plate 3 fixedly connected to the top of the base 1, a plate shaft 4 fixedly connected to the top of the vertical plate 3, a rotating arm 5 rotatably connected to the outer surface of the plate shaft 4, a connecting rod 6 fixedly connected to one end of the rotating arm 5, a buffer cylinder 7 fixedly connected to the bottom end of the connecting rod 6, a spring 8 installed inside the buffer cylinder 7, a T-shaped rod 9 slidably connected to the inner wall of the buffer cylinder 7, a lower pressure plate 10 installed at the bottom of the T-shaped rod 9, and an alternating eccentric motion mechanism installed on the base 1.

[0017] Through the above technical solution, in the process of processing and pressing paper packaging boxes, the paper packaging box needs to be placed in the processing groove 2 first. Through the alternating eccentric motion mechanism, the two sets of lower pressure plates 10 can alternately squeeze different positions of the packaging box. During this period, the position of the packaging box can be manually adjusted.

[0018] Specifically, the alternating eccentric motion mechanism includes a motor 11 fixedly installed inside the base 1, a drive shaft 12 fixedly connected to the output end of the motor 11, and a drive gear 13 fixedly sleeved on the outer surface of the drive shaft 12.

[0019] With the above technical solution, when the motor 11 drives the drive gear 13 to rotate through the drive shaft 12, the transmission gear 15, which is meshed with the drive gear 13, will rotate synchronously.

[0020] Specifically, a lower drive shaft 14 is rotatably connected to the outer surface of the base 1, and a transmission gear 15 is fixedly sleeved on the outer surface of the lower drive shaft 14, and the outer surface of the transmission gear 15 meshes with the outer surface of the drive gear 13.

[0021] Through the above technical solution, the lower drive shaft 14, the transmission gear 15 and the eccentric wheel 16 rotate synchronously. First, the transmission gear 15 is driven by the rotation of the drive gear 13, and then the lower drive shaft 14 and the eccentric wheel 16 rotate accordingly during the rotation process.

[0022] Specifically, an eccentric wheel 16 is fixedly sleeved on the outer surface of the lower moving shaft 14, and an upper fixed shaft 17 is fixedly connected to the outer surface of the base 1.

[0023] Through the above technical solution, the outer surface of the eccentric wheel 16 is slidably connected to the inner side of the first swing arm 18 and the second swing arm 19 (that is, the side of the two sets of swing arms that are close to each other is always in contact with the surface of the eccentric wheel 16).

[0024] Specifically, a first swing arm 18 is rotatably connected to the outer surface of the upper fixed shaft 17, and a second swing arm 19 is rotatably connected to the outer surface of the upper fixed shaft 17.

[0025] Through the above technical solution, the first swing arm 18 and the second swing arm 19 can drive the corresponding rotating arm 5 through the guide rod 20 and the counterweight ball 21 at their top, so that the rotating arm 5 can rotate along the plate shaft 4.

[0026] Specifically, the top of the first swing arm 18 and the second swing arm 19 are both provided with guide rods 20, and the end of the rotating arm 5 away from the connecting rod 6 is movably installed with a counterweight ball 21, and the outer surface of the counterweight ball 21 is fixedly connected to the top of the guide rod 20.

[0027] Through the above technical solution, the counterweight ball 21 plays a role in pushing and pulling the rotating arm 5 in conjunction with the guide rod 20. On the other hand, when the relatively pointed part of the eccentric wheel 16 does not touch the inner side of the first swing arm 18 or the second swing arm 19, the corresponding rotating arm 5 will be pressed down at the end near the counterweight ball 21 due to the presence of the counterweight ball 21, that is, the pressure plate 10 at the other end of the rotating arm 5 will not be moved down to the position of contacting the packaging box below.

[0028] Working principle: During the processing and pressing of paper packaging boxes, the paper packaging box is first placed in the processing groove 2. Then, the motor 11 is turned on to drive the drive shaft 12 to rotate. During this process, the drive gear 13 will rotate synchronously. In turn, the drive gear 13 will drive the transmission gear 15, which is meshed with it, to rotate. This will drive the lower drive shaft 14 and the eccentric wheel 16 to rotate. When the eccentric wheel 16 rotates, its relatively pointed tip (protruding part) pushes against the first swing arm 18 or the second swing arm 19, causing it to rotate along the upper fixed shaft 17. As a result, the corresponding guide rod 20 at the top of the first swing arm 18 or the second swing arm 19 will be pushed upwards. (If the swing arm is not pushed by the protruding part of the eccentric wheel 16, the guide rod 20 at its top will not push upwards.) During the upward pushing process of the guide rod 20, it will push the corresponding swing arm 5 through the counterweight ball 21 (during this period, the counterweight ball 21 will move flexibly inside the swing arm 5 to cooperate in pushing the swing arm 5), thereby causing the other end of the swing arm 5 to gradually press down. Finally, the connecting rod 6 drives the buffer cylinder 7 to move down synchronously. During this period, the T-shaped rod 9 will drive the pressure plate 10 to move down synchronously. When the pressure plate 10 comes into contact with the paper packaging box, the spring 8 inside the buffer cylinder 7 is gradually squeezed. Therefore, the squeezing force exerted by the pressure plate 10 on the packaging box gradually increases from a relatively light flexible pressure, rather than a direct pressure. Direct, hard pressure can leave indentations, scratches, or even damage to the surface of paper packaging boxes, which are relatively fragile. Gradually increasing, flexible pressure acts as an adaptation process. The initial light pressure does not damage the surface, and as the pressure slowly increases, the box is evenly stressed, effectively preventing surface damage caused by sudden, strong pressure and ensuring the integrity of the packaging's appearance. As the protruding part of the eccentric wheel 16 gradually moves away from the inside of the first swing arm 18 or the second swing arm 19, it gradually slides towards another set of swing arms (if the protruding part of the eccentric wheel 16 was previously pressed against the first...). The inner side of the swing arm 18 (now it is against the inner side of the second swing arm 19) will then move down synchronously with the corresponding lower pressure plate 10 of the swing arm (same principle as above). In the process of the two sets of lower pressure plates 10 alternately moving down to press the paper packaging box, the pressure is applied in stages, and each time it only acts on a local area. The stress distribution is more dispersed, reducing the risk of single-point overload and thus reducing the possibility of structural damage. By pressing in stages, it can be ensured that each corner is pressed individually, reducing the number of missed areas, thereby improving the overall sealing performance. That is, the alternating pressing has significant advantages in protecting the packaging box structure, improving sealing performance, adapting to diverse needs and saving energy through step-by-step and precise control.
