Technical Field

[0001] This utility model relates to the field of cardboard box processing technology, specifically a cardboard box quick bending device. Background Technology

[0002] Cardboard boxes are the most widely used packaging products, and the processing of various cardboard boxes and cartons often requires bending the cardboard into various required shapes. In current cardboard box production, to facilitate assembly, the cardboard is pre-bent to form specific creases that clearly indicate the direction of subsequent folds.

[0003] Chinese utility model patent application number 202223300176.8 provides a carton bending device. The device uses a telescopic rod to push the slide table vertically downward. The bending knife installed on the lower surface of the slide table can press down on the upper surface of the carton. As the bending knife moves downward, the bending area on the lower surface of the carton contacts the upper surface of the bending block. At the same time, the bottom end of the bending knife engages with the groove, thus completing the bending process of the carton surface.

[0004] However, during the use of the above equipment, it was found that when the positioning plate is fixed on the bending frame during the bending process, if the carton size is large or small, the bending point of the carton cannot accurately correspond to the bending knife when the positioning plate positions the edge of the carton, resulting in inaccurate bending position and affecting product quality. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a rapid cardboard box bending device, which solves the problem mentioned in the background technology that when a fixed positioning plate is used with cardboard boxes of different sizes, the bending point of the cardboard box cannot be accurately aligned with the bending blade.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0023] Example 1:

[0024] Please see Figures 1-5 A rapid cardboard box bending device includes an operating table 1, a moving groove 12 in the middle of the operating table 1, and conveyor belts 2 at both ends of the moving groove 12. A limit component 4 is provided on one end of the moving groove 12. The limit component 4 includes a fixed plate 41, which is provided on both sides of the conveyor belt 2. A motor 42 is fixedly installed on the fixed plate 41 on one side of the conveyor belt 2. The output end of the motor 42 is connected to a one-way threaded rod 43. The one-way threaded rod 43 is rotatably mounted on the fixed plate 41. A moving block 44 is screwed onto the one-way threaded rod 43. A motor 46 is fixedly installed on the top of the moving block 44. A limit plate 47 is connected to the output end of the motor 46. The end of the limit plate 47 away from the motor 46 is rotatably mounted on the moving block 44 on the other side of the conveyor belt 2. The moving block 44 on the other side of the conveyor belt 2 is slidably mounted on a slide rod 45.

[0025] A sliding plate is fixedly installed in the middle of the moving trough 12, and electric telescopic rods 11 are installed at both ends of the sliding plate in the middle of the moving trough 12.

[0026] Specifically, the operator places the cardboard box onto the conveyor belt 2 at one end of the workbench 1. Driven by the conveyor belt 2, the box passes through the moving trough 12 and moves to the other end of the workbench 1. A trolley installed in the moving trough 12 prevents the cardboard box from falling significantly as it passes through. The trolley supports the cardboard box. Under normal conditions, the limiting plate 47 in the limiting assembly 4 is perpendicular to the conveyor belt 2, blocking the cardboard box being transported. Below, one end of it is attached to the limiting plate 47. Depending on the size of the carton, in order to make the fold on the carton correspond to the bending knife 52, the motor 42 drives the one-way threaded rod 43 to rotate. Through the screw connection between the one-way threaded rod 43 and the moving block 44, the moving block 44 drives the limiting plate 47 to slide along the slide rod 45, so as to make it easy to accurately adjust the distance between the limiting plate 47 and the bending knife 52, so that the fold of the carton can be accurately moved below the bending knife 52.

[0027] Before bending, the electric telescopic rods 11 at both ends of the slide push the push plate to fit against the side of the carton. Then, the electric telescopic rods 11 on both sides of the carton clamp and fix the carton to prevent it from tilting during bending, which would reduce the bending effect. After the bending assembly 5 completes the bending of the carton, the motor 46 drives the limiting plate 47 to rotate, causing the limiting plate 47 to tilt. This allows the bent carton to pass through the gap between the limiting plate 47 and the conveyor belt 2, making it easier for the operator to process it.

[0028] Example 2:

[0029] To meet the requirements for different bending spacings, please refer to [link / reference]. Figures 1-5 Based on embodiment 1, a lifting rod 31 is fixedly installed on the top of the periphery of the moving groove 12, a bending assembly 5 is provided on the lifting rod 31, and a connecting plate 3 is fixedly installed on the top of the lifting rod 31.

[0030] The bending assembly 5 includes a lifting plate 51, the top of which is connected to the output end of the electric telescopic rod 32, which is fixed on the connecting plate 3.

[0031] A bending blade 52 is provided below the lifting plate 51. Both ends of the bending blade 52 are fixedly connected to sliders 521. The sliders 521 are slidably mounted on the fixed rod 53. A support plate 55 is fixedly connected to the bottom of the fixed rod 53. A bending groove 56 is fixedly provided on the support plate 55. The bending groove 56 is adapted to the bending blade 52. The slider 521 is connected to the support plate 55 through a spring 54.

[0032] An adjustment assembly 6 is provided on the lifting plate 51. The adjustment assembly 6 includes a motor 61. The output end of the motor 61 is connected to a bidirectional threaded rod 63. Both ends of the bidirectional threaded rod 63 are screwed with connecting blocks 62. A sliding groove 64 is provided on the lifting plate 51. Both ends of the connecting blocks 62 pass through the sliding groove 64 and are fixedly connected to the bending knife 52. Both ends of the connecting blocks 62 are adapted to the sliding groove 64.

[0033] Specifically, the motor 61 drives the bidirectional threaded rod 63 to rotate, causing the connecting block 62, which is helically connected to the bidirectional threaded rod 63, to move in opposite directions or away from each other along the slide groove 64. This allows the connecting block 62 to drive the bending blade 52 to move, thereby adjusting the spacing between the bending blades 52 to meet the bending requirements of different widths. During the movement of the bending blade 52, the fixed rod 53 can drive the support plate 55 and the bending groove 56 to move, so that the bending blade 52 and the bending groove 56 always correspond to each other.

[0034] During bending, the electric telescopic rod 32 extends to control the lifting plate 51 to descend along the lifting rod 31. During this process, the lifting plate 51 drives the bending knife 52 to move downward. The support plate 55 is set in the moving groove 12. The support plate 55 is blocked by the bottom of the moving groove 12. During the downward movement of the bending knife 52, the support plate 55 is always in contact with the moving groove 12, which causes the distance between the bending knife 52 and the support plate 55 to become closer. This causes the slider 521 to slide along the fixed rod 53 and squeeze the spring 54. During the downward movement of the bending knife 52, the bending knife 52 is adapted to the bending groove 56, so that the bending knife 52 can bend the carton, thus creating creases on the carton. The fixed rod 53 is used to guide the movement of the bending knife 52, so that the bending knife 52 can accurately enter the bending groove 56.

[0035] Working principle: When the equipment is in use, the spacing between the bending blades 52 is first adjusted according to the bending requirements of different widths. The double-threaded rod 63 is driven by motor 3 61 to rotate, causing the connecting block 62, which is helically connected to the double-threaded rod 63, to move in opposite directions or away from each other along the slide groove 64, thereby adjusting the spacing between the bending blades 52. Then, the operator adjusts the distance between the limiting plate 47 and the bending blades 52 according to the different sizes of cartons. The unidirectional threaded rod 43 is driven by motor 1 42 to rotate, so that the moving block 44 helically connected to the unidirectional threaded rod 43 can drive the limiting plate 47 to slide along the slide rod 45, thereby adjusting the distance between the limiting plate 47 and the bending blades 52.

[0036] When bending the cardboard box, the operator places the box on the conveyor belt 2. Driven by the conveyor belt 2, the box passes through the moving groove 12 and moves to another conveyor belt 2, so that one end of the box is in contact with the limiting plate 47, causing the bending point to be below the bending knife 52. The electric telescopic rod 32 extends to control the lifting plate 51 to drive the bending knife 52 to move downward, so that the box is bent by the cooperation of the bending knife 52 and the bending groove 56, resulting in creases on the box. After the box is bent, the motor 46 drives the limiting plate 47 to rotate, so that the bent box can pass through the gap between the limiting plate 47 and the conveyor belt 2, making it easier for the operator to process it later.
