Description

Technical Field

[0001] This utility model relates to the technical field of color box processing equipment, and in particular to a color box folding edge device. Background Technology

[0002] A color box folding machine is a specialized piece of machinery used in the production process of paper box packaging. It primarily performs folding operations on pre-printed and die-cut color box cardboard, precisely folding the originally flat cardboard along pre-designed crease lines to initially form a three-dimensional box shape, preparing it for subsequent processes such as gluing and assembly.

[0003] For example, a color box folding machine disclosed in Chinese Patent Publication No. CN219360438U includes a base, which is set on the ground; an L-shaped mounting frame, which is mounted on the base and consists of a horizontal plate and a vertical plate; a lifting and pressing mechanism, which is set below the horizontal plate; and a rotation adjustment mechanism, which is used to improve the safety of folding.

[0004] However, when folding the edges of the color box, the color box cardboard may rotate and shift, making it difficult for the folding plate to accurately align with the color box cardboard for folding. Due to the inaccurate folding position, the color box cardboard is prone to damage such as skewed creases and edge tears during the folding process. These damaged color box cardboards cannot meet the requirements of high-quality packaging and can only be discarded or reworked, which directly leads to a significant increase in the processing cost of the color box cardboard. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art where the color box cardboard rotates and shifts, making it difficult for the folding edge plate to accurately align with the color box cardboard for folding operations, and to propose a color box folding device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a color box folding device, comprising a folding table, wherein an adsorption adjustment mechanism and a stamping folding mechanism are fixedly installed on the top of the folding table, the adsorption adjustment mechanism comprising an adsorption component and a rotation adjustment component, the adsorption component comprising a cardboard adsorber, a telescopic rotating chamber, an air chamber, a return spring and a folding chamber, one end of the cardboard adsorber being movably engaged inside the telescopic rotating chamber, one end of the telescopic rotating chamber being rotatably engaged at the input end of the air chamber, the output end of the air chamber being fixedly connected to the input end of a vacuum pump, the return spring being movably sleeved on one end of the cardboard adsorber, and the rotation adjustment component being tractively connected to the outside of the telescopic rotating chamber.

[0007] Preferably, the cardboard absorber includes an absorbent plate, an absorbent rod, and limiting blocks. The absorbent plate is fixedly connected to one end of the absorbent rod, and several limiting blocks are fixedly installed on the outside of the other end of the absorbent rod.

[0008] Preferably, the interior of the telescopic rotating chamber is fixedly installed with several limiting partitions arranged in a ring, and one end of the limiting block is movably engaged between two limiting partitions.

[0009] Preferably, the rotation adjustment assembly includes a transmission pulley, a toothed synchronous belt, a drive pulley, and a drive assembly. The transmission pulley is fixedly installed on the outside of the telescopic rotating chamber. One end of the toothed synchronous belt is connected to the outside of the transmission pulley, and the other end of the toothed synchronous belt is connected to the outside of the drive pulley. The drive end of the drive assembly is connected to the center of the drive pulley.

[0010] Preferably, the rotation adjustment assembly includes a transmission pulley, a toothed synchronous belt, a drive pulley, and a drive assembly. The transmission pulley is fixedly installed on the outside of the telescopic rotating chamber. One end of the toothed synchronous belt is connected to the outside of the transmission pulley, and the other end of the toothed synchronous belt is connected to the outside of the drive pulley. The drive end of the drive assembly is connected to the center of the drive pulley.

[0011] Preferably, support legs are fixedly installed at the four corners of the folding compartment, and one end of the cardboard suction device is located inside the folding compartment.

[0012] Preferably, the stamping and folding mechanism includes a mounting side frame and an electric telescopic rod. The electric telescopic rod is fixedly installed on one side of the mounting side frame, and a pressure plate is fixedly installed on the drive end of the electric telescopic rod.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the telescopic rotating chamber is driven to rotate by the rotating adjustment component. The telescopic rotating chamber drives the cardboard suction device and the color box cardboard to rotate, so that the color box cardboard is facing the folding chamber. The electric telescopic rod in the stamping and folding mechanism can accurately drive the pressure plate to stamp and fold the color box cardboard, avoiding edge damage caused by rotational deviation, improving the yield of color box folding and reducing the processing cost of color box cardboard.

[0015] 2. In this utility model, the suction rod is reset by the reset spring, so that the suction plate at one end of the suction rod is located at the upper end of the folding chamber, thus completing the reset operation. This ensures that the suction plate adsorbs and supports the color box cardboard before stamping and folding, preventing one side of the color box cardboard from contacting the upper edge of the folding chamber. This ensures that the upper edge of the folding chamber will not scratch the outer surface of the color box cardboard when it is rotated and adjusted, thereby improving the smoothness and flatness of the outer surface of the color box cardboard.

[0024] The specific settings and functions of this embodiment are described below. The color box cardboard to be folded is placed above the cardboard suction unit 31.

Subsequently, the camera detects that the color box cardboard has shifted. The drive component 44 in the rotation adjustment component 4 drives the drive pulley 43 to rotate.

[0026] The overall effect of this embodiment is that when the color box cardboard is stamped, the pressure plate 521 drives the color box cardboard and the cardboard suction device 31 to retract into the folding chamber 35. The folding plate in the folding chamber 35 performs the folding operation on the color box cardboard. The suction rod 312 in the cardboard suction device 31 is pushed to the bottom of the telescopic rotating chamber 32. After the folding is completed, the reset spring 34 drives the suction rod 312 to reset, so that the suction plate 311 at one end of the suction rod 312 is located at the upper end of the folding chamber 35, completing the reset operation. This ensures that the suction plate 311 first absorbs and supports the color box cardboard before stamping and folding, preventing one side of the color box cardboard from contacting the upper edge of the folding chamber 35. This ensures that the upper edge of the folding chamber 35 will not scratch the outer surface of the color box cardboard when the color box cardboard is rotated and adjusted, thereby improving the smoothness and flatness of the outer surface of the color box cardboard.

[0027] The usage and working principle of this device are as follows: Place the cardboard box to be folded above the cardboard suction unit 31. The vacuum pump extracts the gas between the cardboard suction unit 31 and the cardboard box, causing the cardboard box to be adsorbed onto one end of the suction plate 311 in the cardboard suction unit 31. Then, the camera detects the cardboard box shifting, and the drive component 44 in the rotation adjustment assembly 4 drives the drive pulley 43 to rotate. Under the transmission of the toothed synchronous belt 42, the drive pulley 43 drives the transmission pulley 41 to rotate. The transmission pulley 41 drives the telescopic rotating chamber 32 to rotate, which in turn drives the cardboard suction unit 31 and the cardboard box to rotate. The color box cardboard faces the folding chamber 35. The electric telescopic rod 52 in the stamping and folding mechanism 5 can accurately drive the pressure plate 521 to stamp and fold the color box cardboard. When the color box cardboard is stamped, the pressure plate 521 drives the color box cardboard and the cardboard suction device 31 to retract into the folding chamber 35. The folding plate in the folding chamber 35 performs the folding operation on the color box cardboard. The suction rod 312 in the cardboard suction device 31 is pushed to the bottom of the telescopic rotating chamber 32. After the folding is completed, the return spring 34 drives the suction rod 312 to return to its original position, so that the suction plate 311 at one end of the suction rod 312 is located at the top of the folding chamber 35, completing the return operation.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
