One end of the third spring (42) is fixedly connected to the support plate (41), and the other end of the third spring (42) is fixedly connected to the outer wall of the clamping rod (40). A clamping hole (43) is opened on the top of the slide plate (37), and the end of the clamping rod (40) is clamped and matched with the clamping hole (43).

9. The device for recycling waste from wood-plastic board production according to claim 8, characterized in that: The bottom end of the material discharge plate (23) is fixedly connected to a rubber belt (24), the end of the rubber belt (24) is fixedly connected to a material guide plate (25), the material guide plate (25) extends into the collection box (36), and the two sides of the material guide plate (25) are respectively fixedly connected to the side plates (44).

10. A recycling method for a wood-plastic board production waste recycling device, applicable to the wood-plastic board production waste recycling device according to claim 9, characterized in that: The following steps are involved: S1. Put the waste wood-plastic board into a box (1), drive one of the first rotating shafts (4) to rotate through a motor (16), drive the other first rotating shaft (4) to rotate through a gear (6), and drive the second rotating shaft (7) to rotate through a synchronous wheel (9), so that the two first rotating shafts (4) and the second rotating shaft (7) can rotate synchronously, and the board is crushed by the crushing knives (5) on the outer walls of the first rotating shaft (4) and the second rotating shaft (7), the guard plate (2) can prevent the wood chips generated by the crushing from splashing out of the outside of the box (1), and the block board can be discharged to the multiple crushing knives (5) through the guide plate (3), so that the board is crushed in a centralized manner; S2, the crushed debris falls on the unloading plate (23), and the dust collector (19) can collect the dust generated in the box (1) through the plurality of suction nozzles (20) and discharge it through the chip discharge pipe (21), thereby centrally processing the dust in the box (1) and preventing it from spreading to the outside; S3, when the second rotating shaft (7) rotates, the first connecting arm (11) is driven to rotate through the third rotating shaft (10), the first connecting arm (11) drives the second connecting arm (13) to rotate through the connecting shaft (12), and the second connecting arm (13) drives the unloading plate (23) to slide up and down along the outer wall of the second sliding rod (30) through the connecting rod (14), at this time, the connecting rod (14) slides along the inner wall of the second connecting arm (13), and the unloading plate (23) can quickly discharge the broken plate on the top into the collection box (36) through the shaking; S4, when the upper end of the blanking plate (23) shakes, under the elastic force of the first spring (29), the sealing plate (26) can always seal and block the second through hole (18), and at the same time, the sealing plate (26) can adapt to the shaking of the blanking plate (23) and slide along the first slide bar (28), so as to prevent dust inside the box body (1) from spreading outward; S5. Insert the slides (37) on both sides of the collection box (36) into the corresponding slide holes (35) of the side plate (44) respectively, so that the side plate (44) rolls along the supporting wheel (34) in the supporting plate (33), and the inclined surface of one end of the side plate (44) is squeezed against the corresponding clamping rod (40) until, under the elastic force of the third spring (42), the end of the clamping rod (40) is clamped into the clamping hole (43) on the side plate (44), thereby fixing the collection box (36). After filling, hold the handle (39) and pull the connecting plate (38) upward until the clamping rod (40) is removed from the clamping hole (43) on the side plate (44), so that the collection box (36) can be quickly disassembled.
