Description

Technical Field

[0001] This utility model belongs to the field of cardboard box production technology, specifically relating to a conveying and correction mechanism for a corrugated cardboard box production line. Background Technology

[0002] In the modern production process of corrugated boxes, efficient and continuous material transfer is the core link to ensure the efficiency and automation level of the production line. Corrugated boxes usually need to be precisely transferred between a series of processes such as forming, printing, slotting, gluing, and stacking through a continuously running conveyor belt system.

[0003] However, the conveyor belt itself inevitably generates varying degrees of mechanical vibration. These vibrations can cause corrugated boxes, which should be moving in a straight line along the predetermined path, to gradually shift in position during transport. That is, their axis of travel gradually deviates from the center line of the conveyor belt. If this shift is not corrected in time, it will not only lead to inaccurate positioning of the boxes in subsequent processes, but also affect the integrity of the printed patterns, the accuracy of the slotting, and the quality of the bonding, thus reducing the pass rate of the finished boxes. Utility Model Content

[0004] The purpose of this utility model is to provide a conveyor correction mechanism for a corrugated cardboard box production line to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a corrugated cardboard box production line conveying and correction mechanism, including a support frame, a first conveyor belt and a second conveyor belt are provided between the inner walls of the two sides of the support frame, and the first conveyor belt and the second conveyor belt are on the same horizontal plane, a correction component for corrugated cardboard boxes is provided between the inner walls of the two sides of the support frame, and a pushing component for corrugated cardboard boxes is provided on both sides of the support frame.

[0006] The correction assembly includes a fixed frame installed between the inner walls of both sides of the support frame. The fixed frame is located between the first conveyor belt and the second conveyor belt and is on the same horizontal plane as the first conveyor belt and the second conveyor belt. A strip-shaped groove is formed on the upper surface of the fixed frame. Multiple correction wheels are fixed at equal intervals on the top of the fixed frame and in the groove by bearing seats.

[0022] 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.

[0023] Please see Figures 1-3 This utility model provides a conveyor belt correction mechanism for a corrugated cardboard box production line, including a support frame 1. A first conveyor belt 4 and a second conveyor belt 5 are bolted between the inner walls of both sides of the support frame 1, and the first conveyor belt 4 and the second conveyor belt 5 are on the same horizontal plane. A correction assembly 3 for corrugated cardboard boxes is provided between the inner walls of both sides of the support frame 1. The correction assembly 3 includes a fixing frame 302 bolted between the inner walls of both sides of the support frame 1. The fixing frame 302 is located between the first conveyor belt 4 and the second conveyor belt 5, and is bolted between the inner walls of both sides of the support frame 1. The first conveyor belt 4 and the second conveyor belt 5 are on the same horizontal plane. A strip-shaped groove 303 is opened on the upper surface of the fixed frame 302. Multiple equidistant correction wheels 304 are fixed to the top of the fixed frame 302 and inside the groove 303 by bearing seats. A fixed plate 301 is fixed to one side of the support frame 1 by bolts. The correction wheels 304 are inclined toward the fixed plate 301. The tops of the multiple correction wheels 304 protrude from the upper surface of the fixed frame 302. The inclination angle of the correction wheels 304 is in the range of 30° to 60°.

[0024] When the corrugated carton is conveyed on the first conveyor belt 4 and the second conveyor belt 5, if a positional deviation occurs, the corrugated carton will come into contact with the correction wheel 304 during its movement because the correction wheel 304 is tilted towards the fixed plate 301 and its top protrudes from the upper surface of the fixed frame 302. The correction wheel 304 will generate a lateral friction force on the corrugated carton, thus pushing the corrugated carton towards the fixed plate 301. The fixed plate 301 will block the corrugated carton, causing it to slide along the fixed plate 301 and gradually return it to the correct conveying path. This will calibrate the tilted corrugated carton to the same horizontal direction as the fixed plate 301, avoiding inaccurate positioning of the carton in subsequent processes, which would affect the integrity of the printed pattern, the accuracy of the slotting, and the quality of the bonding.

[0025] It should be noted that both the first conveyor belt 4 and the second conveyor belt 5 are existing technologies, and those skilled in the art can set them according to actual needs, which will not be elaborated here.

[0026] In this embodiment, the support frame 1 is provided with push-off components 6 for corrugated cardboard boxes on both sides. The push-off components 6 include mounting brackets 601 fixed to both sides of the support frame 1 by bolts, and the mounting brackets 601 are located above the second conveyor belt 5. The mounting brackets 601 are U-shaped. The bottom of the mounting brackets 601 is fixed with a double-moving linear motor 602 by bolts. Both moving parts of the double-moving linear motor 602 are fixed with push plates 603 by bolts. The push plate 603 on the side of the fixed plate 301 in the initial position is on the same plane as the end of the fixed plate 301.

[0027] The corrugated carton moves along the fixing plate 301 onto the push plate 603 closest to the fixing plate 301. Once the carton is fully in contact with the push plate 603, the double-actuator linear motor 602 is activated. The two actuators of the motor drive the corresponding push plates 603 inwards. During this movement, the push plates 603 push the carton accurately to the preset position, ensuring precise positioning in subsequent processes and further improving the integrity of the printed pattern, the accuracy of the slotting, and the quality of the bonding. After the pushing operation is complete, the double-actuator linear motor 602 drives the actuators to return the push plates 603 to their initial position.

[0028] It should be noted that the double-acting linear motor 602 is existing technology. The model of the double-acting linear motor 602 is DH100. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0029] In this embodiment, multiple evenly distributed drag-reducing components 2 are provided on the opposite side of the two push plates 603 and the side of the fixed plate 301 away from the support frame 1. The drag-reducing component 2 includes a groove 201, which is opened on the opposite side of the two push plates 603 and the side of the fixed plate 301 away from the support frame 1. A roller 202 is rotatably installed in the groove 201 through a bearing, and the roller 202 is vertically arranged. The gap between the multiple rollers 202 and the first conveyor belt 4 or the second conveyor belt 5 is smaller than the thickness of the corrugated cardboard box to be conveyed. The corrugated cardboard box will contact the rollers 202 during the movement, and the rollers 202 will rotate. The rotation of the rollers 202 can greatly reduce the friction force on the corrugated cardboard box, so that the corrugated cardboard box can move more smoothly and avoid the surface wear or movement obstruction of the corrugated cardboard box due to excessive friction.

[0030] The use of this utility model involves the following steps:

[0031] S1: When the corrugated carton is being transported on the first conveyor belt 4 and the second conveyor belt 5, if a positional deviation occurs, the corrugated carton will come into contact with the corrugated carton during its movement because the correction wheel 304 is tilted toward the fixed plate 301 and its top protrudes from the upper surface of the fixed frame 302. The correction wheel 304 will generate a frictional force component (i.e., lateral thrust) on the corrugated carton pointing toward the fixed plate 301. The fixed plate 301 will block the corrugated carton, causing it to slide along the fixed plate 301 and gradually return it to the correct transport path.

[0032] S2: The corrugated cardboard box will continue to move forward along the fixed plate 301, and the corrugated cardboard box will be transferred to the push plate 603 on the side close to the fixed plate 301. When the corrugated cardboard box is completely in contact with the push plate 603 on the side close to the fixed plate 301.

[0033] S3: At this time, the double-moving linear motor 602 is started. The two moving parts of the double-moving linear motor 602 drive the corresponding push plate 603 to move inward towards each other. During the movement of the push plate 603, the corrugated carton can be pushed accurately to the preset position.

[0034] S4: At the same time, the corrugated cardboard box will come into contact with the roller 202 during the movement, and the roller 202 will rotate. The rotation of the roller 202 can greatly reduce the friction force on the corrugated cardboard box.

[0035] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.

[0036] The electronic components and modules used in this utility model can all be parts that are commonly used in the market and can achieve the specific functions in this case. The specific models and sizes can be selected and adjusted according to actual needs.
