Description

Technical Field

[0001] This utility model relates to the field of wood door manufacturing and processing technology, specifically to a wood chip crushing device for wood door manufacturing. Background Technology

[0002] Wood chips are the powdery residue left over from wood processing. They can be used to manufacture composite boards, such as MDF (medium-density fiberboard). They can also be used as raw materials for papermaking. After manufacturing wooden doors, the leftover scraps can be crushed to obtain wood chips, facilitating the reuse of these scraps. This requires the use of wood chip crushing equipment.

[0003] Existing wood chip crushing devices sometimes fail to completely crush some scraps and pieces. Repeated crushing of these incompletely crushed scraps is inconvenient and cannot meet usage requirements. Therefore, we propose a wood chip crushing device for wooden door manufacturing to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a wood chip crushing device for wooden door manufacturing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wood chip crushing device for wooden door manufacturing, comprising:

[0006] A crushing cylinder is a hollow cavity with an open end. A feed hopper is fixedly installed on the top wall of the crushing cylinder, and a through groove is formed on the bottom wall of the crushing cylinder. A screening plate is installed in the through groove. A discharge nozzle is fixedly installed on the bottom wall of the crushing cylinder at the position of the through groove. A cover plate is fixedly installed at the opening of the crushing cylinder. Two rotating rods are rotatably installed on the side wall of the crushing cylinder away from the cover plate via bearings. Crushing rollers are fixedly installed on the two rotating rods on the surface of the inner cavity of the crushing cylinder. Gears are fixedly installed on both rotating rods and the two gears are meshed together. A first drive motor is fixedly installed on the side wall of the crushing cylinder. The output end of the first drive motor is drivenly connected to one of the rotating rods. A rotating column is rotatably installed on the cover plate via bearings. Multiple annularly distributed mounting rods are fixedly welded to one end of the rotating column in the inner cavity of the crushing cylinder. A tilting plate is fixedly installed on the mounting rod. One side wall of the tilting plate is in contact with the inner wall of the crushing cylinder. A second drive motor is fixedly installed on the cover plate. The output end of the second drive motor is drivenly connected to the rotating column.

[0007] Preferably, a fixed seat is fixedly welded to both sides of the discharge nozzle. A U-shaped rod is slidably connected to the fixed seat through a through hole. One end of the U-shaped rod is fixedly installed on the bottom wall of the screening plate. An installation ring is fixedly welded to the surface of the U-shaped rod below the fixed seat. A tension spring is sleeved on the U-shaped rod. The two ends of the tension spring are fixedly connected to the fixed seat and the installation ring, respectively.

[0008] Preferably, the inner cavity of the discharge nozzle is adapted to the screening plate.

[0009] Preferably, a push rod is fixedly welded to the top of the U-shaped rod located below the second drive motor, a roller is fixedly installed at the top of the push rod, and a cam is fixedly installed on the rotating column, with the cam aligned with the roller.

[0010] Preferably, four support legs are fixedly welded to the outer wall of the crushing cylinder.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In the crushing process, the present invention can drive the rotating column to rotate through the second drive motor, thereby driving multiple tipping plates to rotate in the inner cavity of the crushing cylinder to turn the incompletely crushed scraps onto the two crushing rollers for repeated crushing, so that the scraps are crushed more completely and the crushing effect is improved.

[0013] 2. When the second drive motor of this utility model drives the rotating column to rotate, it can drive the cam to rotate. During the rotation, the cam will cyclically squeeze the roller. When the roller is squeezed by the cam, it will move downward. The push rod pushes the U-shaped rod to move downward, stretching the tension spring. When the cam rotates to disengage from the roller, the stretched tension spring returns to its original position, driving the U-shaped rod to return to its original position. This realizes the up-and-down reciprocating movement of the U-shaped rod, thereby driving the screening plate to shake up and down in the discharge nozzle, improving the screening effect of the screening plate.

A discharge nozzle 5 is fixedly installed on the bottom wall of the crushing cylinder 1 at the position of the through groove 3. A cover plate 6 is fixedly installed at the opening of the crushing cylinder 1. Two rotating rods 7 are rotatably installed on the side wall of the crushing cylinder 1 away from the cover plate 6 via bearings. Crushing rollers 8 are fixedly installed on the surface of the two rotating rods 7 located in the inner cavity of the crushing cylinder 1. Gears 9 are fixedly installed on both rotating rods 7. The gear 9 is meshed and connected. A first drive motor 10 is fixedly installed on the side wall of the crushing cylinder 1. The output end of the first drive motor 10 is connected to a rotating rod 7. A rotating column 11 is rotatably installed on the cover plate 6 through a bearing. A plurality of annularly distributed mounting rods 12 are fixedly welded to one end of the rotating column 11 located in the inner cavity of the crushing cylinder 1. A turning plate 13 is fixedly installed on the mounting rod 12. One side wall of the turning plate 13 is in contact with the inner wall of the crushing cylinder 1. A second drive motor 14 is fixedly installed on the cover plate 6. The output end of the second drive motor 14 is connected to the rotating column 11.

[0021] Fixed seats 15 are fixedly welded to both sides of the discharge nozzle 5. A U-shaped rod 16 is slidably connected to the fixed seat 15 through a through hole. One end of the U-shaped rod 16 is fixedly installed on the bottom wall of the screening plate 4. An installation ring 17 is fixedly welded to the surface of the U-shaped rod 16 below the fixed seat 15. A tension spring 18 is sleeved on the U-shaped rod 16. The two ends of the tension spring 18 are fixedly connected to the fixed seat 15 and the installation ring 17, respectively. Through the cooperation of the fixed seat 15, the U-shaped rod 16 and the tension spring 18, the screening plate 4 can be supported at the bottom wall of the crushing cylinder 1.

[0022] The inner cavity of the discharge nozzle 5 is adapted to the screening plate 6, and the screening plate 6 can slide in the inner cavity of the discharge nozzle 5.

[0023] A push rod 19 is fixedly welded to the top of the U-shaped rod 16 located below the second drive motor 14. A roller 20 is fixedly installed on the top of the push rod 19. A cam 21 is fixedly installed on the rotating column 11. The cam 21 is aligned with the roller 20. When the rotating column 11 rotates, it can drive the cam 21 to rotate.
