Description

Technical Field

[0001] This utility model relates to the field of packaging box fastening machine technology, specifically an automatic fastening machine for flip-top packaging boxes. Background Technology

[0002] The automatic snap-fitting machine for flip-top packaging boxes is an automated device specifically designed to automatically and accurately position and snap-fit ​​the box body and lid of flip-top packaging boxes. Its core function is to achieve efficient assembly of packaging boxes through mechanical structures, sensors, and a control system, replacing the traditional manual snap-fitting process and significantly improving production efficiency and product quality consistency. The packaging box moves to the pressure plate, where the lid is pressed down. Then, a hydraulic cylinder drives a piston rod to move, causing the pressure plate to press down and tighten the lid against the box body. Another set of hydraulic cylinders drives a piston rod to press down and bend the insert plates at both ends of the lid. Finally, a set of hydraulic cylinders drives a piston rod to press the lid tightly against the side of the box body, at which point the insert plates are inserted into the gaps on both sides of the box body.

[0003] During the conveying process, the box may shift position due to equipment vibration, or the box may not be centered on the conveyor belt. This causes the inserts at both ends of the lid to fail to fully fold into place when bent, affecting the accurate insertion of the inserts into the gaps at both ends of the lid. Therefore, an automatic snap-fit ​​machine for flip-top packaging boxes is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic snap-fit ​​machine for flip-top packaging boxes to solve the problems mentioned in the background section. To solve the above technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to an automatic snap-fit ​​machine for flip-top packaging boxes, comprising:

[0006] An automatic fastening machine includes a conveyor belt, a gantry frame, a pressure plate, and a fastening plate. The gantry frame is fixed to the upper end of the conveyor belt, the pressure plate is fixed to the lower end of the hydraulic telescopic rod in the middle of the gantry frame, and the fastening plate is movably connected to the side of the pressure plate through the hydraulic telescopic rod.

[0007] The alignment assembly includes a first opening, a support rod, a second opening, a first support plate, an inclined plate, a movable plate, and a first spring column. The first opening is located at the middle of both ends of the gantry frame. One end of the support rod is fixed to the middle of both ends of the pressure plate, and the other end is inserted into the first opening. The second opening is located at the end of the support rod located at the first opening. The first support plate is inserted into the second opening. The inclined plate is fixed to the lower end of the first support plate. The movable plate is inserted into the first opening. One end of the first spring column is fixed to one end of the movable plate, and the other end is fixed to the side of the gantry frame.

[0008] Furthermore, the alignment component also includes a threaded tube, which is fixed to one end of the support rod and communicates with the inside of the second opening.

[0009] Furthermore, the alignment assembly also includes a first push plate and a second support plate. The first push plate is fixed to one end of the moving plate, the second support plate is fixed to the other end of the moving plate, and the other end of the first spring column away from the gantry is fixed to the side of the second support plate.

[0010] Furthermore, the inclined plate faces downwards and aligns with the upper inclined surface of the movable plate.

[0011] Furthermore, two other fastening plates are movably connected to both sides of the same end of the pressure plate where the fastening plate is located via hydraulic telescopic rods.

[0012] Furthermore, it also includes a compensation component, which includes a second spring post and a second push plate. The second spring post is fixed to one end of the middle buckle plate, and the second push plate is fixed to the lower end of the second spring post.

[0014] This utility model has the following beneficial effects:

[0015] This invention utilizes a aligning assembly. When the box moves below the pressure plate, a hydraulic cylinder drives a piston rod to move, causing the pressure plate to move downwards. The downward movement of the pressure plate causes the support rod to move downwards, which in turn causes the inclined plate below the first support plate to move downwards. When the inclined plate reaches the moving plate, it continues to move downwards, causing the moving plate to move along the first opening towards the inside of the gantry frame. This causes the first push plate to move towards the center of the conveyor belt. The two first push plates align the box. This design allows the box to be centered and aligned, improving the accuracy of the lid and box body when they are fastened together. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-4 As shown, this utility model is an automatic snap-fit ​​machine for flip-top packaging boxes, comprising:

[0026] The automatic fastening machine includes a conveyor belt 10, a gantry frame 11, a pressure plate 12, and a fastening plate 13. The gantry frame 11 is fixed to the upper end of the conveyor belt 10, the pressure plate 12 is fixed to the lower end of the hydraulic telescopic rod in the middle of the gantry frame 11, and the fastening plate 13 is movably connected to the side of the pressure plate 12 through the hydraulic telescopic rod.

[0027] Two other snap plates 13 are movably connected to both sides of the pressure plate 12 at the same end of the snap plate 13 via hydraulic telescopic rods;

[0028] The conveyor belt 10 is used to transport packaging boxes, the gantry frame 11 provides support, the pressure plate 12 is used to press the box lid onto the box body, and the buckle plate 13 is used to fasten the box lid onto the box body.

[0029] The alignment assembly includes a first opening 20, a support rod 21, a second opening 22, a first support plate 24, an inclined plate 25, a movable plate 26, and a first spring column 28. The first opening 20 is located at the middle of both ends of the gantry frame 11. One end of the support rod 21 is fixed to the middle of both ends of the pressure plate 12, and the other end is inserted into the first opening 20. The second opening 22 is located at the end of the support rod 21 located at the first opening 20. The first support plate 24 is inserted into the second opening 22. The inclined plate 25 is fixed to the lower end of the first support plate 24. The movable plate 26 is inserted into the first opening 20. One end of the first spring column 28 is fixed to one end of the movable plate 26, and the other end is fixed to the side of the gantry frame 11.

[0030] The alignment assembly also includes a threaded tube 23, which is fixed to one end of the side of the support rod 21 and communicates with the inside of the second opening 22.

[0031] The alignment assembly also includes a first push plate 27 and a second support plate 29. The first push plate 27 is fixed to one end of the movable plate 26, the second support plate 29 is fixed to the other end of the movable plate 26, and the other end of the first spring column 28 away from the gantry frame 11 is fixed to the side of the second support plate 29.

[0032] The inclined plate 25 faces downward and matches the upper inclined surface of the movable plate 26;

[0033] The first opening 20 facilitates the movement of the support rod 21 and the movable plate 26. The support rod 21 provides support. The second opening 22 is used to connect the first support plate 24. The threaded tube 23, in conjunction with screws, is used to fix the first support plate 24. The first support plate 24 provides support. The inclined plate 25 provides a pushing function. The movable plate 26 is used to drive the first push plate 27 to move. The first push plate 27 is used to straighten the packaging box. The first spring post 28 has a reset function. The second support plate 29 is used to fix one end of the first spring post 28.

[0034] Working principle:

[0035] Move the first support plate 24 to a suitable position and tighten the screw in the threaded tube 23 to fix the first support plate 24 in the second opening 22. When the box body moves below the pressure plate 12, the hydraulic cylinder drives the piston rod to move, causing the pressure plate 12 to move down. The downward movement of the pressure plate 12 causes the support rod 21 to move down, which in turn causes the inclined plate 25 below the first support plate 24 to move down. When the inclined plate 25 moves to the moving plate 26, it continues to move down, causing the moving plate 26 to move along the first opening 20 towards the inside of the gantry 11, and causing the first push plate 27 to move towards the middle of the conveyor belt 10. When the pressure plate 12 presses the box cover onto the box body, the inclined plate 25 stops moving. The moving plate 26 pushes the first push plate 27 to straighten the box body. After the box cover and box body are fastened, the pressure plate 12 moves up, the inclined plate 25 disengages from the moving plate 26, the first spring column 28 extends, causing the second support plate 29 to move away from the gantry 11, and then causing the moving plate 26 and the first push plate 27 to reset.

[0036] This step ensures the box is centered and aligned, improving the accuracy of the lid and body when they snap together.

[0037] Please see Figure 1 , Figure 4 As shown, this embodiment, based on the above embodiment, further includes:

[0038] The compensation component includes a second spring post 31 and a second push plate 32. The second spring post 31 is fixed to one end of the middle buckle plate 13, and the second push plate 32 is fixed to the lower end of the second spring post 31.

[0039] The compensation component also includes a third opening 30, which is opened at one end of the middle buckle plate 13, and the second spring post 31 is fixed in the third opening 30.

[0040] The third opening 30 is used to connect the second spring post 31, which has a telescopic function, and the second push plate 32 is used to push the lid.

[0041] Working principle:

[0042] When the packaging box moves on the conveyor belt 10 to below the pressure plate 12, due to inertia, if it stops at a position that exceeds the original stopping position, the hydraulic cylinder drives the piston rod to rotate the buckle plate 13 by 90 degrees. This, in turn, causes the second spring post 31 and the second push plate 32 to move closer to the box cover. The second push plate 32 pushes the box cover to fit against the side of the box body, so that the side inserts are inserted into the gaps in the box body. The second spring post 31 is designed to prevent the buckle plate 13 from being too close to the box cover after flipping over, which would cause the box cover and the box body to be squeezed during pushing, thus preventing damage to the packaging box.

[0043] This step can further improve the integrity of the box after the lid and body are fastened together.
