Description

Technical Field

[0002] Plywood is a three-layer or multi-layer plate-like material made by peeling wood segments into veneers or planing wood blocks into veneers, and then gluing them with adhesive. It is usually made of an odd number of veneers, and the fibers of adjacent veneers are glued perpendicular to each other. Plywood is often trimmed during the production process to ensure the flatness of the edge of the board, and the cut edge waste will be crushed. However, when the existing crushing facilities crush the edge waste of plywood, the plywood edge waste is too long to be put into the crushing tank, resulting in the need for workers to manually break the edge waste during the crushing process, and then put it into the crushing tank for crushing.

A through hole 38 is provided on the inner bottom surface of the feed hopper 5 near the side of the lower cutter 37. The through hole 38 serves to accommodate the feed roller 35. Two bearing shafts 11 are rotatably installed between the front and rear end surfaces inside the feed hopper 5. The bearing shafts 11 serve to support the feed roller 35, and the two bearing shafts 11 are arranged vertically.

[0019] Both ends of the load-bearing shaft 11 pass through the front and rear ends of the feed hopper 5. The front ends of the two load-bearing shafts 11 are coaxially inlaid with connecting gears 12. The connecting gears 12 allow the two load-bearing shafts 11 to rotate towards each other.

[0021] A large pulley 21 is coaxially inlaid at the rear end of the upper load-bearing shaft 11, and a small pulley 22 is coaxially inlaid at the middle of the outer surface of the connecting shaft 17. The large pulley 21 and the small pulley 22 can slow down the rotation speed of the load-bearing shaft 11, thereby slowing down the speed of conveying waste. A No. 2 synchronous belt 20 is connected between the small pulley 22 and the large pulley 21. A motor frame 18 is fixedly installed on the upper side of the fixed frame 19. The No. 2 synchronous belt 20 plays a transmission role. A No. 1 servo motor 10 is fixedly installed at the end of the motor frame 18.

When the pressing frame 15 drives the upper cutter 13 to move up and down continuously, it will also drive the tooth plate 28 to move up and down continuously through the pushing frame 7. At this time, the guide sleeve 27 slides on the guide edge frame 26 to assist the movement of the tooth plate 28, so that the moving tooth plate 28 continuously drives the swing gear 31 to reciprocate, thereby driving the crushing tank 1 to swing, so that the waste in the crushing tank 1 can be swung to fully contact with the crushing rod 24, so as to fully crush the waste.

[0023] A pushing frame 7 is fixedly installed on the side of the extending frame 14, and the pushing frame 7 plays a role in pushing the tooth plate 28. A guide sleeve 27 is fixedly installed on the end of the pushing frame 7. The side of the guide sleeve 27 is fixed to the upper part of the side of the tooth plate 28. A guide rib frame 26 is fitted inside the guide sleeve 27. The guide sleeve 27 and the guide rib frame 26 play a role in guiding the tooth plate 28. The two ends of the guide rib frame 26 pass through the upper and lower ends of the guide sleeve 27. A frame seat 29 is fixedly installed on the lower end of the guide rib frame 26. The frame seat 29 plays a role in fixing the guide rib frame 26, and the end of the frame seat 29 is fixed to the tank rack 3.

The discharge port 2 plays a role of discharging the crushed waste. The discharge port 2 can be covered by threaded installation to prevent the waste from falling out during the crushing process. A crushing rod 24 is rotatably installed in the middle of the upper end of the crushing tank 1. The crushing rod 24 extends into the interior of the crushing tank 1. The crushing rod 24 plays a role of crushing the waste. It is an existing technology to install a crushing knife at the end and use the rotating crushing rod 24 to drive the crushing knife to crush the material, and it has been widely used, so it is not elaborated here. A No. 2 servo motor 34 is fixedly installed on the side of the crushing tank 1. The No. 2 servo motor 34 drives the crushing rod 24 to rotate. The output end of the No. 2 servo motor 34 and the upper end of the crushing rod 24 are coaxially inlaid with a connecting pulley 25. The connecting pulley 25 serves to connect the No. 1 synchronous belt 9. A No. 1 synchronous belt 9 is connected between the two connecting pulleys 25. The No. 1 synchronous belt 9 connects the output end of the No. 2 servo motor 34 and the crushing rod 24.

[0025] During crushing, the edge waste of the long strip of plywood is placed in the feeding hopper 5. At this time, the end of the waste passes through the two feeding rollers 35. Then the No. 1 servo motor 10 works to drive the connecting shaft 17 to rotate, so as to drive the pressing ear 16 to rotate through the rotating connecting shaft 17, and then drive the pressing frame 15 to move continuously to push and pull the upper cutter 13. At this time, the guide column 33 slides in the guide sleeve 23 to assist the movement of the upper cutter 13, so as to use the upper cutter 13 that moves up and down continuously to cut the edge waste of the plywood into small segments. In this process, the connecting shaft 17 will also drive the bearing shaft 11 to rotate through the No. 2 synchronous belt 20 when rotating, so that the feeding roller 35 on the bearing shaft 11 rotates towards each other under the action of the two connecting gears 12, so as to align the two feeding rollers 3 5, so as to push the edge waste of the plywood between them to the upper cutter 13 for cutting, and the cut waste in small segments falls into the crushing tank 1. At this time, the No. 2 servo motor 34 works to drive the crushing rod 24 to rotate through the No. 1 synchronous belt 9 to crush the waste falling into the crushing tank 1. In this process, when the pressing frame 15 drives the upper cutter 13 to move up and down continuously, it will also drive the tooth plate 28 to move up and down continuously through the pushing frame 7. At this time, the guide sleeve 27 slides on the guide edge frame 26 to assist the movement of the tooth plate 28, so that the swing gear 31 is continuously driven to reciprocate through the moving tooth plate 28, thereby driving the crushing tank 1 to swing, so that the waste in the crushing tank 1 can be swung to fully contact with the crushing rod 24, so as to fully crush the waste.
