[0022] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0023] The following disclosure provides many different embodiments or examples for implementing different solutions of the present invention.

[0024] Reference Figures 1 to 3 As shown, in one embodiment of the utility model, a chip cleaning device for wood processing equipment includes a bracket 1 and a first driving module 2 for driving the bracket 1 to move horizontally, a chip suction frame 3, a negative pressure module 4 and a second driving module 5 are provided on the bracket 1, and the second driving module 5 drives the chip suction frame 3 to move up and down;

[0025] The chip suction rack 3 includes a top plate 31, a side plate 32 and a blocking plate 33. The top plate 31 extends horizontally. There are two side plates 32 and they are arranged on both sides of the top plate 31 along its length direction. The two side plates 32 are both located below the top plate 31. The distance between the upper ends of the two side plates 32 is greater than the distance between the lower ends of the two side plates 32. The two blocking plates 33 are located at both ends of the top plate 31 along its length direction. The top plate 31, the side plates 32 and the blocking plates 33 enclose a chip suction chamber 34. A chip suction slit 35 of the chip suction chamber 34 is formed between the lower ends of the two side plates 32. The chip suction chamber 34 is connected to the negative pressure module 4.

[0026] The negative pressure module 4 is connected to the external negative pressure device to generate negative pressure in the chip suction chamber 34, so that the wood chips can be adsorbed. The chip suction chamber 34 shrinks from top to bottom, so that the area of ​​the chip suction gap 35 becomes smaller and the suction force is stronger. At the same time, the chip suction rack 3 can be raised and lowered. When sucking chips, the height of the chip suction rack 3 is controlled to make the chip suction gap 35 as close to the surface of the wooden board as possible, but not completely in contact with the surface of the wooden board, so that the airflow can enter the chip suction gap 35, and the airflow is used to carry the wood chips, so that the chip suction effect is better;

[0027] The first driving module 2 can drive the bracket 1 to move horizontally, thereby driving the chip suction frame 3 to move horizontally, and can move along the length direction of the wooden board to absorb the wood chips on the wooden board.

[0028] In this embodiment, the distance between the lower ends of the two side plates 32 is 4-9 mm, and the width of the chip suction slit 35 is minimized while ensuring that the chip suction slit 35 can suck in wood chips;

[0029] Preferably, the distance between the lower ends of the two side plates 32 is 6 mm.

[0030] In this embodiment, the negative pressure module 4 includes a negative pressure tube body 41 and a connecting tube body 42. The negative pressure tube body 41 is parallel to the top plate 31. Both ends of the negative pressure tube body 41 are provided with elbows 43. The elbows 43 are connected to the debris suction chamber 34 through a connecting piece 44.

[0031] The lower end of the connecting tube body 42 is connected to the negative pressure tube body 41, and the upper end of the connecting tube body 42 is connected to the external negative pressure equipment through a hose;

[0032] This structure solves the problem that the chip suction rack 3 is difficult to connect to an external negative pressure device. The external negative pressure device forms a negative pressure in the negative pressure tube body 41 by exhausting air. The connecting piece 44 is a hollow structure. The negative pressure tube body 41 exhausts air to the chip suction chamber 34 through the connecting piece 44, so that the chip suction chamber 34 generates suction. The hose facilitates the lifting and lowering of the chip suction rack 3, and the pipe will not be torn when the chip suction rack 3 is lifted and lowered.

[0033] Preferably, the lower end of the connecting tube body 42 is connected to the middle part of the negative pressure tube body 41, and the two connecting parts 44 are symmetrically connected to the top plate 31. Therefore, when the connecting tube body 42 is evacuated, negative pressure can be evenly generated at both ends of the negative pressure tube body 41, and the connecting part 44 can evenly extract the gas in the chip suction chamber 34, so that the negative pressure generated in the chip suction chamber 34 is more balanced.

[0034] In this embodiment, a third driving module 6 is provided on the outer wall of the negative pressure tube body 41, a baffle 61 is provided on the output end of the third driving module 6, and a slot 421 is provided on the connecting tube body 42. The baffle 61 can be inserted into the slot 421 or away from the slot 421 when the third driving module 6 is driven. When the baffle 61 is inserted into the slot 421, the baffle 61 will block the connecting tube body 42, thereby preventing the hose from evacuating air. At this time, the chip suction gap 35 will not absorb wood chips, and the chip cleaning device can be in an idle state.

[0035] In this embodiment, the first driving module 2 includes a rack arranged on the external workbench, a gear set on the bracket 1, and a motor driving the gear to rotate. The gear is meshed with the rack, and the motor drives the gear to rotate, so that the gear can move along the rack, and the bracket 1 can also move horizontally;

[0036] The second driving module 5 and the third driving module 6 are both cylinders.

[0037] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
