Technical Field
[0001] This utility model relates to the field of paper box edge reinforcement and folding technology, and in particular to an automatic paper box edge reinforcement and folding device. Background Technology
[0002] In today's packaging industry, paper boxes are an extremely common and widely used form of packaging, carrying important functions such as protecting products, facilitating transportation, and enhancing product display. With the continuous growth of market demand and the increasing variety of products, the requirements for the production efficiency and quality of paper box packaging are also constantly rising. Automatic edge-reinforced folding equipment for paper boxes has emerged to meet the needs of large-scale, high-quality paper box production. It realizes the transformation of paper boxes from flat cardboard to finished paper boxes with a stable structure and good edge reinforcement through automation, thereby replacing the traditional manual folding method, improving production efficiency, reducing labor costs, and ensuring the precision and consistency of paper boxes during the folding process. It better meets the diverse requirements of various products for paper box packaging. Many industries, including food, daily necessities, and electronic products, have an urgent need for this type of automated equipment.
[0003] Traditional cardboard box folding equipment is mostly built on relatively simple mechanical transmission principles. In the folding section, it mainly relies on a combination of components such as mechanical linkages, cams, and cylinders to achieve the folding action. For example, the extension and retraction of the cylinder drives the linkage, causing it to push the edge of the cardboard box along a specific trajectory to bend and gradually form the shape of the box. For reinforcing the edges of the cardboard box, a common method is to use an adhesive tape applicator. A motor-driven tape roller delivers and applies tape to the edges of the cardboard box, thereby strengthening the connection and preventing it from unraveling during subsequent transportation and use. The entire equipment operates using a simple electrical control system, which controls the coordinated work of various mechanical components according to a preset time sequence and action flow to complete the tasks of folding and reinforcing the edges of the cardboard box.
[0004] However, traditional paper box folding equipment has significant shortcomings in terms of folding precision. Because it relies on a relatively simple mechanical structure for folding, it is often difficult to accurately control the angles of each corner and edge fold. This leads to asymmetrical corner folds and irregular edge folds in actual production, which seriously affects the appearance quality and overall structural stability of the paper box. It cannot meet the current requirements for high-quality paper box packaging, which has become one of the important factors restricting the improvement of paper box production efficiency and product quality. Therefore, an automatic edge reinforcement folding equipment for paper boxes is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an automatic edge reinforcement and folding device for paper boxes, which aims to improve the problems of insufficient folding precision of paper boxes in the prior art, which easily leads to asymmetrical folding angles and irregular edge folding.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An automatic edge-reinforced folding device for paper boxes includes a housing, inside which a paper box forming and folding device is installed, and a fixing plate is fixedly connected inside the housing. An angle adjustment component is provided on the upper surface of the fixing plate, and the angle adjustment component is used to adjust the paper box.
[0008] The angle adjustment assembly includes a fixed frame, which is fixedly connected to the bottom of the fixed plate. A motor is fixedly connected inside the fixed frame, and a rotating plate is fixedly connected to the output end of the motor. The rotating plate rotates inside the fixed plate. A support frame is fixedly connected to the top of the rotating plate, and a cylinder is fixedly connected to the top of the support frame.

A connecting block is rotatably connected inside the connecting rod. An adjustment plate is fixedly connected to the top of the connecting block, and a connecting block is fixedly connected to the bottom of the adjustment plate. A connecting block is rotatably connected to the outer wall of the connecting block, and a connecting block is fixedly connected to the bottom of the connecting block.

A limit component is provided on the top of the adjustment plate, and the limit component is used to fix the position of the paper box.

[0010] The limiting component includes a connecting plate and a connecting post, wherein the connecting plate is fixedly connected to the top of the adjusting plate, and the connecting post is fixedly connected to the top of the connecting plate;

[0012] A second support frame is fixedly connected to the top of the connecting column, a second cylinder is fixedly connected to the lower surface of the second support frame, and a transmission shaft is fixedly connected to the output end of the second cylinder.
[0013] As a further description of the above technical solution:
[0014] The top of the drive shaft is fixedly connected to a symmetrical sliding plate, and the top of the sliding plate is fixedly connected to a clamping plate.
[0015] As a further description of the above technical solution:
[0016] The slide plate is slidably connected to a slide rail, which is fixedly connected to the upper surface of the support frame 2.

[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, the cylinder output end drives the transmission block and slider to slide inside, thereby further driving the connecting rod to move synchronously. The movement of the connecting rod forces the adjusting plate to move off-center. At the same time, the motor output end drives the rotating plate to rotate inside the fixed plate, thereby achieving the effect of quickly adjusting the angle of the paper box. This solves the problem of traditional equipment making it difficult to accurately control the angle of the paper box, and improves the production efficiency of the paper box folding process and the overall forming quality efficiency of the paper box.
[0023] 2. In this utility model, the output end of cylinder two drives the transmission shaft to retract, and the movement of the transmission shaft causes the slide plate to slide on the outer wall of the slide rail. This causes transmission rod one to move synchronously, and the movement of transmission rod one drives the rotating shaft and transmission rod two to move, so that the two clamping plates move inward synchronously, thereby achieving the effect of quickly limiting the position of the paper box. This solves the problem of paper box position deviation and difficulty in accurate positioning in traditional equipment, and improves the accuracy of paper box processing. Attached Figure Description

Detailed Implementation
[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Reference Figure 1 - Figure 3 The present invention provides an embodiment of an automatic edge-reinforced folding device for paper boxes, comprising a housing 1. The housing 1 serves as the external frame of the device, providing a stable support platform to ensure that the internal components can be accurately positioned during operation and to reduce the impact of vibration on the device. A paper box forming and folding device 2 is provided inside the housing 1, which is mainly responsible for folding and forming the paper box. A fixing plate 3 is fixedly connected inside the housing 1, and an angle adjustment component is provided on the upper surface of the fixing plate 3. The angle adjustment component is used to adjust the paper box.
[0032] The angle adjustment assembly includes a fixed frame 4, which is fixedly connected to the bottom of a fixed plate 3. A motor 5 is fixedly connected inside the fixed frame 4. The motor 5 drives a rotating plate 6 to adjust the paper direction. The output end of the motor 5 is fixedly connected to the rotating plate 6, which rotates inside the fixed plate 3. A support frame 7 is fixedly connected to the top of the rotating plate 6, and a cylinder 8 is fixedly connected to the top of the support frame 7 to provide power to drive the rear assembly. A transmission block 9 is fixedly connected to the output end of the cylinder 8, and the transmission block 9 slides inside the support frame 7, ensuring the cylinder 8... For precise adjustment of 8, a slider 15 is fixedly connected to the side wall of the transmission block 9. A connecting rod 10 is rotatably connected inside the slider 15. A connecting block 11 is rotatably connected inside the connecting rod 10. An adjusting plate 12 is fixedly connected to the top of the connecting block 11 to provide a certain support force and ensure the stability of the component. A connecting block 2 13 is fixedly connected to the bottom of the adjusting plate 12. A connecting block 3 14 is rotatably connected to the outer wall of the connecting block 2 13. The bottom of the connecting block 3 14 is fixedly connected to the upper surface of the rotating plate 6. A limit component is provided on the top of the adjusting plate 12 to fix the position of the paper box.
[0033] Specifically, during the automatic edge-reinforced folding process of the cardboard box, when the initial angle of the cardboard box deviates or needs to be folded at a specific non-standard angle, the output end of the motor 5 drives the rotating plate 6 to rotate inside the fixed plate 3, thereby achieving rapid adjustment of the cardboard box's orientation. The motor 5 provides power, and the movement of the rotating plate 6 allows the cardboard box on the fixed plate 3 to flexibly change direction. At the same time, the output end of the cylinder 8 drives the transmission block 9 to slide inside the support frame 7. The pushing force of the cylinder 8 is converted into the sliding action of the transmission block 9. When the transmission block 9 slides, it further triggers the synchronous sliding of the slider 15 inside the support frame 7. To ensure the continuity of the transmission components, when the slider 15 slides inside the support frame 7, it interacts with the connecting block 11 through the connecting rod 10, causing one side of the connecting rod 10 to rotate inside the connecting block 11. The rotation of one side of the connecting rod 10 causes the entire device to shift upward, which in turn causes the adjusting plate 12 to move upward synchronously. During the movement of the adjusting plate 12, the connecting block 2 13 and the connecting block 3 14 on the other side of the adjusting plate 12 form a mechanical linkage. When the connecting block 2 13 rotates inside the connecting block 3 14, it provides stability for the movement of the adjusting plate 12, avoiding instability or deviation during the movement.
[0034] Reference Figure 4 The limiting assembly includes a connecting plate 16 and a connecting column 17. The connecting plate 16 is fixedly connected to the top of the adjusting plate 12, and the connecting column 17 is fixedly connected to the top of the connecting plate 16, serving as an extension and support to ensure the vertical stability of the entire limiting assembly. A support frame 18 is fixedly connected to the top of the connecting column 17, providing stable support for the cylinder 19. The cylinder 19 is fixedly connected to the lower surface of the support frame 18 to provide driving force and drive the transmission shaft 20 to move back and forth. The output end of the cylinder 19 is fixedly connected to the transmission shaft 20. A symmetrical sliding plate 21 is fixedly connected to the top of the transmission shaft 20. A clamping plate 22 is fixedly connected to the top of the sliding plate 21. The function of the clamping plate 22 is to physically fix the cardboard box to ensure that the cardboard box will not shift or tilt during angle adjustment and reinforcement.
[0035] Specifically, during the operation of the automatic edge-reinforcing and folding cardboard box equipment, when the cardboard box is prone to positional displacement due to external forces during transport or processing, affecting the accuracy of subsequent processes, power is provided through the output end of cylinder 219. The contraction movement of cylinder 219 drives the transmission shaft 20 to contract. When the transmission shaft 20 begins to move, it forces the slide plate 21 to slide along the track on the outer wall of the slide rail 23. The smooth movement of the slide plate 21 is based on the stable structural design of the slide rail 23. The function of the slide rail 23 is to guide the slide plate 21, ensuring that it moves along the correct path. The movement of the slide plate 21 directly causes the clamping plate 22 to contact the cardboard box, thereby achieving the clamping function.
[0036] Reference Figure 4The slide plate 21 is slidably connected to a slide rail 23, which is firmly fixed to the upper surface of the support frame 2 18, ensuring that the slide plate 21 can slide smoothly along the slide rail 23. The slide rail 23 is fixedly connected to the upper surface of the support frame 2 18. One of the slide plates 21 is rotatably connected to a transmission rod 24, which is rotatably connected to a rotating shaft 25 for transmitting power and ensuring the accuracy of power transmission. The rotating shaft 25 is rotatably connected to a transmission rod 26, which is rotatably connected to the inside of another slide plate 21.
[0037] Specifically, during the movement of the slide plate 21, the clamping plate 22 contacts the surface of the cardboard box, ensuring that the cardboard box is stably placed in a fixed position. When one of the slide plates 21 moves, it not only causes the clamping plate 22 to contact the cardboard box, but also causes the transmission rod 24 to deflect. The deflection of the transmission rod 24 is synchronized with the sliding direction of the slide plate 21, further driving the rotating shaft 25 to rotate. The deflection direction of the rotating shaft 25 is consistent with that of the transmission rod 24, thus achieving precise synchronous rotation of the rotating shaft 25. The rotation of the rotating shaft 25 drives the transmission rod 26 to deflect in the opposite direction through the internal mechanical connection. The reverse movement of the transmission rod 26 causes the other side of the clamping plate 22 to deflect, causing the two clamping plates 22 to move inward synchronously. Due to the synchronous action of the clamping plates 22, the cardboard box can be quickly clamped and fixed, achieving a rapid limiting effect on the cardboard box, ensuring that the cardboard box does not shift in a fixed position, and ensuring the smooth progress of subsequent processing or transportation operations.
[0038] Working Principle: When using this device, the cardboard box is folded and reinforced by the cardboard box forming and folding device 2. During processing, the output end of the motor 5 drives the rotating plate 6 to rotate inside the fixed plate 3, thereby quickly adjusting the orientation of the cardboard box. The output end of the cylinder 8 drives the transmission block 9 to slide inside the support frame 7. When the transmission block 9 slides, it further causes the slider 15 to slide synchronously inside the support frame 7, thereby driving one side of the connecting rod 10 to rotate inside the connecting block 11, causing it to shift upwards. This causes the adjusting plate 12 to move synchronously. When the adjusting plate 12 moves, the connecting block 13 on its other side will... The internal rotation of connecting block 3 14 ensures the stability of the movement of adjusting plate 12, thereby adjusting the angle of the cardboard box. At the same time, the output end of cylinder 2 19 drives the transmission shaft 20 to retract. The movement of the transmission shaft 20 forces the slide plate 21 to slide on the outer wall of the slide rail 23. The movement of the slide plate 21 causes the clamping plate 22 to contact the cardboard box. When one of the slide plates 21 moves, it will drive the transmission rod 1 24 to deflect, thereby causing the rotating shaft 25 to rotate synchronously with it. The rotation of the rotating shaft 25 drives the transmission rod 2 26 to deflect in the opposite direction, causing the two clamping plates 22 to move inward synchronously, achieving the function of quickly limiting the cardboard box.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
