[0019] Embodiment 1: like Figure 1-Figure 5 The technical solution shown in the figure, the present invention provides the following technical solution: In order to solve the problem that the debris generated by the cutting of the wood-plastic board by the production equipment is inconvenient to clean, which will affect the product processing quality and processing efficiency, a rotating mechanism is disclosed: The invention comprises a cutting device 1, a conveying device 2 is arranged on the side of the cutting device 1, a conveying device 3 is arranged on the side of the conveying device 2 away from the cutting device 1, three groups of through grooves 101 are opened on the top of the cutting device 1, a rotating groove 102 is opened on the top of the cutting device 1 near the through groove 101, a motor is installed inside the rotating groove 102, a first rotating wheel 103 is fixed on the output end of the motor, a rotating mechanism for cleaning cutting waste is arranged inside the rotating groove 102, a rotating groove 108 is symmetrically opened at the bottom of the rotating groove 102, a swinging mechanism for improving the waste collection effect is arranged inside the rotating groove 108, and the rotating mechanism comprises a second rotating wheel 104, and the second rotating wheel 104 is fixed on The top of the first rotating wheel 103, the second rotating wheel 104 and the side of the first rotating wheel 103 are all connected with a transmission belt 105, and the transmission belts 105 are symmetrically distributed about the center of the rotating groove 102. The transmission belts 105 are respectively connected to the third rotating wheel 106 away from the inner sides of the first rotating wheel 103 and the second rotating wheel 104. The third rotating wheel 106 is rotatably connected inside the rotating groove 102. The third rotating wheel 106 and the transmission belt 105 are respectively connected to the first rotating wheel 103 and the second rotating wheel 104 to form a transmission connection. A cleaning rod 107 is fixed on the top of the third rotating wheel 106. The cleaning rod 107 penetrates and rotates inside the rotating groove 102, and the cleaning rod 107 is closely attached to the upper surface of the cutting device 1; When the production equipment processes the wood-plastic board, it is necessary to cut the wood-plastic board into specified specifications through the cutting device 1, and then convey the wood-plastic board to the upper surface of the conveying device 3 through the conveying device 2, and then the wood-plastic board is transported away by the conveying device 3. When the wood-plastic board is cut, debris will be scattered on the surface of the cutting device 1, and when it needs to be cleaned, the output end of the starting motor can drive the first rotating wheel 103 and the second rotating wheel 104 to rotate. When the first rotating wheel 103 and the second rotating wheel 104 rotate, they can respectively drive the transmission belt 105 to rotate, and when the transmission belt 105 rotates, it can drive the third rotating wheel 106 to rotate. When the third rotating wheel 106 rotates, it can rotate through the rotating groove 102. When the two third rotating wheels 106 rotate, they can drive the cleaning rod 107 to rotate. The two cleaning rods 107 rotate on the upper surface of the cutting device 1 in a relative motion direction.

[0020] Embodiment 2: like Figure 6-Figure 8 The technical solution shown in the figure, the present invention provides the following technical solution: In order to solve the problem that the debris is easily accumulated when the wood-plastic board production equipment collects the debris, which affects the efficiency of debris processing, on the basis of the first embodiment, a swing mechanism is disclosed: The swing mechanism includes a first bevel gear rod 109, which is rotatably connected inside the rotating groove 108. The side of the first bevel gear rod 109 is meshedly connected with a second bevel gear rod 110, and the teeth of the second bevel gear rod 110 are larger than the teeth of the first bevel gear rod 109. The second bevel gear rod 110 rotates inside the rotating groove 108. A rotating block 111 is fixed to the end of the second bevel gear rod 110 away from the first bevel gear rod 109, and the side of the rotating block 111 away from the center of the circle is rotatably connected with a rotating block 112. The end of the rotating block 112 away from the rotating block 111 is rotatably connected with a reciprocating rod 113. The reciprocating rod 113, the rotating block 112 and the rotating block 111 are transmission-connected. A placement groove 114 is provided on the side of the rotating groove 108 and the bottom of the through groove 101. A collection box 115 is provided inside the placement groove 114, and the collection box 115 is connected to the end of the reciprocating rod 113. When the production equipment cleans the debris of the wood-plastic board, the third rotating wheel 106 can rotate, and when the third rotating wheel 106 rotates, it can drive the first bevel gear rod 109 to rotate. When the first bevel gear rod 109 rotates, it can rotate through the rotating groove 108. When the first bevel gear rod 109 rotates, it can drive the second bevel gear rod 110 on the side to engage and rotate. When the second bevel gear rod 110 engages and rotates, it can also rotate through the rotating groove 108. Since the first bevel gear rod 109 and the second bevel gear rod 110 are of different sizes, the first bevel gear rod 109 can drive the second bevel gear rod 110 to rotate more effortlessly. When the second bevel gear rod 110 rotates, it can drive the rotating block 111 to rotate inside the rotating groove 108. When the rotating block 111 rotates, it can drive the rotating block 112 to move. When the rotating block 112 moves, it can drive the reciprocating rod 113 to move. When the reciprocating rod 113 moves, it can pass through the rotating groove 108. When the reciprocating rod 113 slides, the rotating block 112 can rotate between the reciprocating rod 113 and the rotating block 111. Since the rotating block 111 rotates with the second bevel gear rod 110 as the center, the rotating block 111 can drive the reciprocating rod 113 to slide back and forth inside the rotating groove 108 when it rotates. When the reciprocating rod 113 slides back and forth, it can drive the collecting box 115 to move back and forth. When the collecting box 115 moves, it can roll on the ground through the universal wheels at the bottom, and the collecting box 115 will swing back and forth inside the placement groove 114. When the collecting box 115 swings back and forth, the wood-plastic board debris accumulated inside will be evenly distributed through shaking, preventing the debris from continuously accumulating in one place and leaking out of the collecting box 115, thereby improving the effect of collecting debris by the collecting box 115, reducing the steps of manual intervention, and further improving the cleaning effect of the debris in disguise.

[0021] Embodiment 3: Figure 6 , Figure 8 and Fig. 9 The technical solution shown in the figure, the present invention provides the following technical solution: In order to solve the problem that the collection box 115 of the production equipment is inconvenient to fix and affects the production efficiency, on the basis of the second embodiment, a locking mechanism is disclosed: A snap-fit ​​mechanism for improving the fixing efficiency of the collection box 115 is arranged inside the collection box 115, and the snap-fit ​​mechanism includes a guide block 116, which is fixed on both sides of the collection box 115, and the guide blocks 116 are fixed on both sides of the collection box 115, and a universal wheel is installed at the bottom of the collection box 115, and the guide block 116 slides inside the guide groove 117, and the guide groove 117 is arranged on both sides of the guide block 116, and a rotating rod 118 is rotatably connected to the inside of the collection box 115, and a torsion spring is connected between the rotating rod 118 and the collection box 115, and a side of the collection box 115 away from the rotating rod 118 is symmetrically penetrated with a through hole, and the through hole is slidably connected to the reciprocating rod 113, and a fixed block 119 is fixed on the surface of the rotating rod 118, and the fixed block 119 is snap-fitted with the fixed groove 120, and the fixed groove 120 is respectively arranged at the top and the bottom of the reciprocating rod 113; Before the wood-plastic board production equipment is used, the collection box 115 needs to be positioned first. Moving the collection box 115 first can drive the guide block 116 to move. At the same time, the collection box 115 can be adjusted in position through the universal wheel at the bottom. When the guide block 116 moves to the side of the guide groove 117, it pushes the collection box 115 into the placement groove 114. When the collection box 115 is pushed, the guide block 116 can slide through the guide groove 117. Before the collection box 115 slides into the placement groove 114, the rotating rod 118 is rotated. When the rotating rod 118 rotates, it can rotate through the collection box 115. When the rotating rod 118 rotates, the torsion spring inside the collection box 115 can be tightened. At the same time, when the rotating rod 118 rotates, it can drive the fixed block 119 to rotate. After the rotating rod 118 rotates to a certain angle Continue to push the collecting box 115. When the collecting box 115 is pushed, the perforations on the side can pass through the surface of the reciprocating rod 113. At this time, the collecting box 115 can drive the fixing block 119 to move to the side of the fixing groove 120. When the rotating rod 118 is released, it can be reset by the torsion force of the torsion spring itself. When the rotating rod 118 is reset, it can drive the fixing block 119 to reset. When the fixing block 119 is reset, it can be stuck in the fixing groove 120 at the top and bottom of the reciprocating rod 113 respectively. After the fixing block 119 is stuck with the fixing groove 120, it can be positioned. When the fixing groove 120 is positioned, it can drive the reciprocating rod 113 to connect with the collecting box 115. At this time, the collecting box 115 can be located inside the placement groove 114, which improves the efficiency of connecting the collecting box 115 and further improves the convenience of using the production equipment.
