Description

Technical Field

[0001] This utility model relates to the field of cardboard box manufacturing technology, specifically to an automatic cardboard box stacking mechanism. Background Technology

[0002] Automated cardboard box stacking is the process of orderly stacking manufactured cardboard boxes for storage and transportation. Traditional cardboard box stacking operations have several problems. Firstly, boxes are prone to tilting or tipping over during stacking, resulting in uneven stacking, affecting storage and transportation efficiency, and potentially causing damage. Secondly, during folding and stacking, the cardboard can warp, making the boxes irregular in shape, which is detrimental to subsequent packaging and handling. Furthermore, manual operation is inefficient and cannot meet the needs of large-scale production.

[0003] Publication number CN214988757U describes an automatic cardboard box stacking mechanism. Through a pusher, roller support, and hydraulic lifting rod, it can easily lift cardboard boxes onto a lifting block. The height of the lifted boxes can be easily adjusted as needed, facilitating the stacking of large cardboard boxes. The use of a hydraulic lifting rod for height adjustment solves, to some extent, the problem of height adjustment during cardboard box stacking.

[0004] Then, the technical means mainly focus on lifting and height adjustment of the carton, and lack effective measures to prevent the carton from tilting and the cardboard from warping during the folding process.

[0005] Therefore, in order to address the shortcomings of the existing system, an automatic cardboard box stacking mechanism was proposed. Utility Model Content

[0006] The purpose of this invention is to provide an automatic cardboard box stacking mechanism to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic carton stacking mechanism, comprising: a frame, an anti-tilting mechanism and an anti-lifting mechanism, wherein a horizontal track is provided on one side of the top of the frame, a discharge area is provided on one side of the bottom of the horizontal track, a feeding platform is provided on the other side of the top of the frame, a servo push rod assembly is provided around the feeding platform, and a folding area plate is provided at the connection between the discharge area and the feeding platform;

[0008] The anti-tilt mechanism is used to prevent the carton from tipping over when folded;

[0009] The anti-warping mechanism is used to prevent the cardboard from warping when the carton is folded.

[0010] Furthermore, the anti-tilt mechanism includes a motor assembly, a horizontal helical gear, a vertical helical gear, a rotating shaft, a push plate, a curved arm, and a C-shaped plate. The motor assembly is located on the outer sides of both sides of the folding area plate. A horizontal helical gear is located on one side of the motor assembly. A vertical helical gear is located near the outer side of the horizontal helical gear on the outer side of the folding area plate. A rotating shaft is located at the top of the vertical helical gear. A curved arm is located outside the rotating shaft. A push plate is located at one end of the curved arm. A C-shaped plate is located at one end of the push plate. The tilt angle of the C-shaped plate is the same as the tilt angle of the unfolded parts on both sides of the folding area plate.

[0011] Furthermore, when the push plate moves, it can drive the C-shaped plate to move horizontally inside the folding area plate.

[0012] Furthermore, the vertical helical gear can drive the shaft to rotate when it rotates.

[0013] Furthermore, the anti-tilting mechanism includes a transmission gear, a reset frame, and a rack. The transmission gear is provided on the outside of the vertical helical gear, and a rack is provided on one side of the transmission gear. A reset frame is provided on the back of the rack, and an inclined plate is provided on the top of the rack. The angle of the inclined plate is perpendicular to the inclination angle of the unfolded parts on both sides of the folding area plate.

[0014] Furthermore, the reset frame includes a reset spring, a limiting shaft, and a sliding base, with the sliding base and the rack being interconnected.

[0015] Furthermore, the rack and the inclined plate are fixedly connected, and the rack can drive the inclined plate to move up and down when it moves up and down.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The anti-tilting mechanism of this utility model, through the linkage of components such as motor assembly, horizontal helical gear, and vertical helical gear, makes the C-shaped plate move inside the folding area plate. The C-shaped plate fits against both sides of the carton, effectively preventing it from tipping over. When processing cartons in batches, it avoids problems such as folding errors and equipment jamming caused by carton tipping over, ensures the continuity of folding work, improves production efficiency, and reduces the defect rate.

[0018] 2. The anti-warping mechanism of this utility model utilizes the cooperation of transmission gears, racks and pinions. During the folding process of the carton, the inclined plate moves up and down to fit the folded part of the carton. This effectively prevents the cardboard from warping, ensures the neatness of the folded carton, and makes the shape of the subsequently stacked cartons uniform, which is convenient for storage and transportation, and improves product quality and corporate benefits.

[0028] 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.

[0029] like Figures 1-8 As shown, an automatic carton stacking mechanism includes: a frame 7, an anti-tilting mechanism and an anti-lifting mechanism. A horizontal rail 1 is provided on one side of the top of the frame 7, a discharge area 6 is provided on one side of the bottom of the horizontal rail 1, a feeding table 4 is provided on the other side of the top of the frame 7, a servo push rod assembly 5 is provided around the feeding table 4, and a folding area plate 3 is provided at the connection between the discharge area 6 and the feeding table 4.

[0030] The anti-tilt mechanism is used to prevent the carton from tipping over when folded;

[0031] Anti-warping mechanisms are used to prevent the cardboard from warping when the carton is folded.

[0032] The anti-tilt mechanism includes a motor assembly 8, a horizontal helical gear 13, a vertical helical gear 14, a rotating shaft 17, a push plate 15, a curved arm 16, and a C-shaped plate 9. The motor assembly 8 is provided on the outside of both sides of the folding area plate 3. A horizontal helical gear 13 is provided on one side of the motor assembly 8. A vertical helical gear 14 is provided near the outside of the horizontal helical gear 13. A rotating shaft 17 is provided on the top of the vertical helical gear 14. A curved arm 16 is provided on the outside of the rotating shaft 17. A push plate 15 is provided at one end of the curved arm 16. A C-shaped plate 9 is provided at one end of the push plate 15. The tilt angle of the C-shaped plate 9 is the same as the tilt angle of the unfolded part on both sides of the folding area plate 3.

[0033] The anti-tilting mechanism includes a transmission gear 10, a reset frame 11, and a rack 12. The transmission gear 10 is provided on the outside of the vertical helical gear 14. The rack 12 is provided on one side of the transmission gear 10. The reset frame 11 is provided on the back of the rack 12. The inclined plate 2 is provided on the top of the rack 12. The angle of the inclined plate 2 is perpendicular to the inclination angle of the unfolded parts on both sides of the folding area plate 3.

[0034] In this embodiment, the anti-tilt mechanism is optimized by replacing the material of the C-plate 9 with a flexible rubber material with anti-slip texture on its surface. When preventing the carton from tipping over, the flexible rubber C-plate 9 can better fit the surface of the carton, avoiding scratches and damage. At the same time, the anti-slip texture increases friction and enhances the blocking effect. In addition, an angle sensor is added at the pivot 17 to monitor the rotation angle of the crank arm 16 in real time. Through feedback control, the moving distance of the push plate 15 and the C-plate 9 is precisely adjusted so that it can better adapt to the anti-tilt requirements of different sized cartons, further improving the applicability and stability of the anti-tilt mechanism.

[0035] For the anti-warping mechanism, an elastic buffer layer is added to the edge of the inclined plate 2. When the inclined plate 2 moves up and down and contacts the folded part of the carton, the elastic buffer layer plays a buffering role to prevent the inclined plate 2 from colliding with the carton and causing damage. At the same time, a damper is added in the reset frame 11 to adjust the moving speed of the rack 12, so that the movement of the inclined plate 2 is more stable and the anti-warping effect is improved.

[0036] In addition, this embodiment improves the power transmission and control method of the automatic carton stacking mechanism. A servo motor is used to replace the ordinary motor at the motor assembly 8, and a high-precision reducer is equipped. The servo motor can achieve more precise speed and direction control, and the high-precision reducer can increase the torque, making the transmission of components such as the horizontal helical gear 13 and the vertical helical gear 14 more stable and reliable. Through programming settings, the motor speed and torque can be flexibly adjusted according to the material, size and other parameters of different cartons to optimize the anti-tilting and anti-bending effects.

[0037] In terms of control, a sensor network and intelligent control system are introduced. Pressure sensors and position sensors are installed at key locations such as the folding plate 3 and the feeding table 4. The sensors collect information such as the position and force of the carton in real time. Based on this information, the intelligent control system automatically adjusts the working status of components such as the servo push rod assembly 5 and the motor assembly 8. For example, when a change in the size of the carton is detected, the extension distance of the C-shaped plate 9 and the height of the inclined plate 2 are automatically adjusted to realize intelligent and adaptive control of the entire stacking process, thereby improving the versatility and work efficiency of the equipment.

[0038] Working principle: When using this automatic carton stacking mechanism, the raw material is first placed on the top of the feeding table 4 during the automatic stacking process. The servo push rod assembly 5 is activated to apply a pushing force to the outside of the carton moving inside the feeding table 4, so that the raw material of the carton is squeezed and blocked by each other, achieving initial folding. Then, the feeding table 4 transports part of the folded product to the middle position of the folding area plate 3.

[0039] At this time, the anti-tilt mechanism starts working, the motor assembly 8 starts, driving the horizontal helical gear 13 to rotate, the horizontal helical gear 13 meshes with the vertical helical gear 14, driving the vertical helical gear 14 to rotate, the vertical helical gear 14 drives the rotating shaft 17 to rotate, the crank arm 16 on the rotating shaft 17 rotates accordingly, pushing the push plate 15 to move horizontally, the push plate 15 drives the C-shaped plate 9 to move horizontally on the unfolded surface of the inner side of the folding area plate 3, the C-shaped plate 9 is located on both sides of the conveyed product, preventing the product from tipping over, and ensuring the stability of the carton during the folding process;

[0040] At the same time, the anti-warping mechanism plays a role. When the vertical helical gear 14 rotates, it drives the external transmission gear 10 to rotate. The transmission gear 10 meshes with the rack 12, causing the rack 12 to move up and down in the reset frame 11. The reset spring, limit shaft and sliding base inside the reset frame 11 work together to ensure that the rack 12 moves smoothly. The rack 12 drives the top inclined plate 2 to move up and down on the upper end of the unfolded part on both sides of the folding area plate 3 to prevent the unfolded part of the carton product from warping up and to ensure folding accuracy.

[0041] After being processed by the folding plate 3, the carton moves to the discharge area 6 under the action of the horizontal track 1, completing the entire automatic stacking process.

[0042] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
