Description

Technical Field

[0001] The application of the utility model relates to the technical field of pre-press machines, and specifically relates to a device for removing pre-pressed waste boards. Background Art

[0002] In the production and processing of wood-based panels, the panels after sizing and core mending need to go through a pre-pressing process before hot pressing. After pre-pressing, when the panels are conveyed, they will pass through the detection of a detection device. If the quality of the panels does not meet the standard, the detection device will issue an alarm. For the unqualified panels, the common treatment method is to suspend the conveying, remove them from the conveyor, and recycle the waste boards. However, such an operation requires stopping the conveyor, which affects the normal conveying efficiency of the panels and thus affects the overall working efficiency.

Detailed Embodiments

[0019] The following further elaborates on the device of the present utility model in combination with specific embodiments. These embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the device of the present utility model, those skilled in the art can make various changes or modifications to the present utility model, and these equivalent forms also fall within the scope defined by the appended claims of the application.

[0020] Refer to Figures 1 to 2 a structural view of the present utility model, Figure 1 a partial enlarged view at A in, a device for removing pre-pressed waste plates, which includes a recycling conveyor 8 for receiving the crushed plate debris and fragments. Below the output end of the recycling conveyor 8, an elevator 10 is provided. The outlet end of the elevator 10 is butt-connected with a waste recycling bin 11. The recycled materials are finally conveyed into the waste recycling bin 11 through the recycling conveyor 8 and the elevator 10 for subsequent processing.

[0021] On the side of the recycling conveyor 8, there are the first support 4, the second support 6, and the third support 9 arranged in parallel. Inside the first support 4, there is a rotary conveyor 1. Inside the second support 6 and the third support 9, a transition conveyor 2 is arranged by bolts. Inside the middle of the first support 4, there is a bearing. On the left side surface of the rotary conveyor 1, a first pin shaft 5 is connected. The first pin shaft 5 is arranged inside the bearing. On the right side surface of the rotary conveyor 1, a second pin shaft is connected. A collar is rotatably arranged outside the second pin shaft. The end of the collar is connected with a first hydraulic cylinder 7. The bottom of the first hydraulic cylinder 7 is hinged with a hinge seat. The hinge seat is arranged on the ground. By the extension or contraction of the first hydraulic cylinder 7, the rotary conveyor 1 can be controlled to rotate counterclockwise or clockwise around the first pin shaft 5, so that the crushed waste board fragments can enter the conveyor belt of the recycling conveyor 8 through the rotated rotary conveyor 1.

[0022] The tops of the first support 4 and the second support 6 are connected with a top mounting plate 3. On the upper end surface of the top mounting plate 3, there is a second hydraulic cylinder 12. The output end of the second hydraulic cylinder 12 passes through the top mounting plate 3 and is connected with an upper plate 15. Four guide posts 13 are connected at the four corners of the upper plate 15. All four guide posts 13 pass through the top mounting plate 3. A guide sleeve 14 is arranged between the guide post 13 and the top mounting plate 3. Below the upper plate 15, there is a mounting frame 21. The mounting frame 21 and the upper plate 15 are connected by four columns 16 distributed at the corners. At the upper end of the mounting frame 21, there is a driving motor 17. The output end of the driving motor 17 is connected with a driving sprocket 18. The driving sprocket 18 is connected with a driven sprocket 20 through a transmission chain 19. The inner side of the driven sprocket 20 is connected with a rotating shaft 22. The rotating shaft 22 passes through the side wall of the mounting frame 21 and is rotatably arranged with the mounting frame 21 through a bearing. On the outer side of the rotating shaft 22 and inside the mounting frame 21, there is a crushing roller 23. On the circumferential surface of the crushing roller 23, there are crushing cones 24. By the extension or contraction action of the second hydraulic cylinder 12, the upper plate 15 can be made to drive the columns 16, the mounting frame 21, and the crushing roller 23 to descend or ascend. Under normal conditions, the second hydraulic cylinder 12 is in a contracted state, and the crushing roller 23 and the crushing cones 24 do not contact the board. When there is a waste board, the second hydraulic cylinder 12 extends, making the mounting frame 21 drive the crushing roller 23 to descend, so that the crushing cones 24 can contact the waste board. The driving motor 17 rotates to drive the rotating shaft 22 and the crushing roller 23 to rotate through the transmission chain 19, so that the crushing cones 24 continuously knock the waste board passing under the crushing roller 23 during rotation. Since the waste board is of unqualified quality and brittle texture, it can be easily broken. Under the rotation of the crushing roller 23, the passing waste boards are all knocked into pieces and debris by the crushing cones 24 and enter the recycling conveyor 8 along the downwardly inclined rotary conveyor 1.

[0023] When the first hydraulic cylinder 7 contracts to the limit position, the output end of the rotary conveyor 1 is not in contact with the recycling conveyor 8. When the first hydraulic cylinder 7 extends to the limit position, the upper end surface of the rotary conveyor 1 is horizontally arranged and is respectively butted with the transition conveyors 2 arranged on both sides.

[0024] In order to prevent the guide post 13 from disengaging from the guide sleeve 14 during the extension and contraction actions of the second hydraulic cylinder 12, the length of the guide post 13 is greater than the maximum stroke of the second hydraulic cylinder 12, and the output end of the second hydraulic cylinder 12 is tightly connected to the upper plate 15 through two nuts.

[0025] The crushing cone 24 and the crushing roller 23 are movably connected. Threaded holes for threaded connection with the crushing cone 24 are provided on the circumferential surface of the crushing roller 23. The movable connection facilitates maintenance and replacement of the crushing cone 24. The threaded holes are equally spaced in the axial direction of the crushing roller 23 and are evenly arranged in the circumferential direction.

[0026] In the arrangement mode of the crushing cones 24, all the threaded holes can be provided with the crushing cones 24 so that the crushing cones 24 are evenly distributed on the circumferential surface of the crushing roller 23.

[0027] The crushing cones 24 can also be staggered on the crushing roller 23. Staggering the crushing cones 24 can reduce the generation of large strip-shaped broken blocks.

[0028] Furthermore, the structural shape of the crushing cone 24 can be replaced according to the processing requirements. When the crushing cone 24 is of a conical head structure, the broken blocks produced are smaller; when the crushing cone 24 is of a spherical head structure, the broken blocks produced are larger.

[0029] The utility model arranges conveyors with adjustable angles on the conveyor line, completely crushes the unqualified plates in cooperation with the crushing device and conveys them onto the recycling conveyor belt for differential conveyance, realizing the functions of automatically cleaning waste plates, improving the waste plate removal efficiency, and improving the working efficiency.
