Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard processing technology, specifically to a roller conveyor preheating device for corrugated cardboard processing. Background Technology

[0002] Corrugated paper is a sheet-like material made by bonding linerboard and corrugated paper formed by corrugating rollers. It is generally divided into single-wall and double-wall corrugated paperboard, and further classified into five types according to the size of the corrugations: A, B, C, E, and F. Corrugated paper has been invented and used for over a century. It boasts advantages such as low cost, light weight, easy processing, high strength, excellent printability, and convenient storage and handling. Over 80% of corrugated paper can be recycled. It is widely used for packaging food and digital products, is relatively environmentally friendly, and has a broad range of applications.

[0003] Based on existing technology, it has been found that preheating corrugated cardboard is a step in the corrugated cardboard processing. Generally, the corrugated cardboard to be heated is placed on a conveyor for transportation. The heating method usually involves a heating box fixedly installed on the frame of the conveyor, with an electromagnetic heating tube fixedly installed on the top of the heating box. When the corrugated cardboard passes by the electromagnetic heating tube, it is heated accordingly. However, the length of the electromagnetic heating tube cannot be adjusted. If the width of the corrugated cardboard is less than the length of the electromagnetic heating tube, there will be excess heating space, resulting in heat loss. Utility Model Content

[0020] 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.

[0021] Please see Figures 1-4 In this embodiment of the utility model, the roller conveyor preheating equipment for corrugated cardboard processing includes a roller conveyor 1. A heating box 2 is fixed on the frame of the roller conveyor 1. Multiple parallel and equidistant recesses 3 are provided on the top of the heating box 2. An electromagnetic heating rod 4 is fixed in the recess of the recesses 3. A staggered mechanism is provided on the top of the outer side of the heating box 2 to stagger the multiple recesses 3.

[0022] As can be seen from the above connection relationship, each electromagnetic heating rod 4 has a staggered mechanism for position adjustment. The staggered mechanism allows each electromagnetic heating rod 4 to be staggered with each other, thereby changing the lateral heating range. Therefore, it can be adjusted according to the width of the corrugated cardboard to make full use of the heating space.

[0023] Specifically, the recessed frame 3 located in the middle position is fixed to the heating box 2. The other recessed frames 3 are provided with a linear structure between them and the heating box 2 to allow the recessed frames 3 to move linearly. The linear structure includes a fixed column 5 and a rectangular plate 6. The top of the heating box 2 is provided with multiple linear grooves 8, and the fixing degree in the multiple linear structure corresponds one-to-one with the multiple linear grooves 8. One end of the fixed column 5 is fixed to the middle position of the outer side of the corresponding recessed frame 3, and the other end of the fixed column 5 is slidably inserted into the rectangular plate 6. Both ends of the rectangular plate 6 are fixed with fixing blocks 7 that are fixed to the heating box 2.

[0024] As can be seen from the above connection relationship, the straight structure is designed so that the recessed frame 3 can only move in a straight line within the heating box 2.

[0025] Specifically, the offset mechanism includes a rotating shaft 9 and a rotating plate 10. One end of the rotating shaft 9 is fixed to the heating box 2. The rotating shaft 9 is aligned with the recess 3 at the middle position. A first circular hole is opened on the outer side of the rotating plate 10. The other end of the rotating shaft 9 is rotatably installed with the first circular hole. Straight slots 11 are opened on the outer sides of both ends of the rotating plate 10. The fixed column 5 is slidably installed in the straight slots 11. The offset mechanism also includes a moving block 14, a threaded rod 13, and two support blocks 12. Both support blocks 12 are fixed to the heating box 2. A second circular hole is opened on the outer side of the support block 12. The two ends of the threaded rod 13 are rotatably installed in the two second circular holes respectively. A threaded hole is opened on the outer side of the moving block 14. The outer side of the threaded rod 13 is installed in the threaded hole through external thread. A rotating column 15 is slidably embedded in the straight slot 11 at one end of the rotating plate 10. The rotating column 15 is fixed to the moving block 14. A servo motor is fixed on the outer side of one of the support blocks 12. The output shaft of the servo motor is coaxial with the threaded rod 13.

[0026] As can be seen from the above connection relationship: the servo motor drives the threaded rod 13 to rotate through the output shaft, the threaded rod 13 drives the moving column to rotate through the threaded transmission, the moving column moves the rotating plate 10 with the help of the rotating column 15, and the rotating plate 10 pushes each fixed column 5 through the two straight slots 11, so that the fixed columns 5 are staggered with each other, that is, each recess 3 is staggered with each other.

[0027] Specifically, the inner wall of the heating box 2 is coated with an insulating coating for heat preservation.

[0028] Working principle: The servo motor drives the threaded rod 13 to rotate through the output shaft. The threaded rod 13 drives the moving column to rotate through the threaded transmission. The moving column moves the rotating plate 10 through the rotating column 15. The rotating plate 10 pushes each fixed column 5 through the two straight slots 11, so that the fixed columns 5 are staggered with each other, that is, the recessed frames 3 are staggered with each other, that is, the electromagnetic heating rods 4 can be staggered with each other, thereby changing the lateral heating range. Therefore, it can be adjusted according to the width of the corrugated cardboard to make full use of the heating space.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
