Description

Technical Field

[0001] The utility model relates to the technical field of dust removal for a wooden board sliding table saw, in particular to a dust removal device for a wooden board sliding table saw. Background Art

[0002] When the current wooden board sliding table saw is in use, the staff places the wooden board on the top of the equipment, and then turns on the equipment. At this time, the staff pushes the wooden board and then cuts the wooden board. When the cutting is completed, the staff collects the wood chips generated when cutting the wooden board, and the operation is completed.

[0003] Chinese patent publication number CN220008144U discloses a dust removal device for a wooden board sliding table saw. Through the cooperation of a collection box, a duct, a suction fan, a spring, a first set of boxes and a second set of boxes, the device can automatically collect and process the wood chips generated when cutting wooden boards, thereby preventing the wood chips from diffusing into the air and reducing the number of operating steps for the staff, thereby improving work efficiency, effectively reducing the work intensity of the staff and bringing convenience to the staff.

[0004] However, compared with the prior art and comparative documents, in order to reduce the dust generated when cutting the board during use, the existing wooden board sliding table saw is equipped with a corresponding dust removal mechanism, and the impurities and dust absorbed by the dust removal mechanism are finally collected in a collection box. In the collection process, in order to ensure the smoothness of air intake, an exhaust pipe needs to be opened at the collection box, and in order to prevent dust from overflowing, a filter plate needs to be used at the front end of the exhaust pipe for dust prevention. During use, dust is easy to adhere to the surface of the filter, resulting in the inability to quickly remove the gas, reducing the air intake, thereby reducing the dust removal effect.

The extrusion seat 1001 can be subjected to force to apply pressure to the filter plate 9, and the side of the extrusion seat 1001 facing the filter plate 9 is an arc-shaped mechanism. A guide rod 1002 is provided through the extrusion seat 1001. The guide rod 1002 can ensure the stability of the movement of the extrusion seat 1001. A return spring 1003 is provided on the outer side of the guide rod 1002.

[0029] The transmission mechanism 11 includes an eccentric block 1101 located at the lower side of the extrusion seat 1001. The extrusion seat 1001 can be moved horizontally during the rotation of the eccentric block 1101. A support shaft 1102 is fixed in the middle of the eccentric block 1101. The support shaft 1102 can drive the eccentric block 1101 to rotate. A synchronous wheel 1103 is fixed to the outer side of one end of the support shaft 1102, and a synchronous belt 1104 is nested on the outer side of the synchronous wheel 1103.

[0030] like Figure 1-Figure 2 As shown, a motor 4 is installed on one side below the fixed frame 3, and the motor 4 can drive the connecting shaft 5 to rotate. A connecting shaft 5 is fixed at one end of the output shaft of the motor 4, and the connecting shaft 5 can drive the cutting blade 6 to rotate, thereby realizing the cutting of the wooden board, and a cutting blade 6 is fixed on the outer side of the connecting shaft 5, and the top of the cutting blade 6 passes through the top of the fixed frame 3.

[0032] like Figure 5-Figure 6 As shown, the dust removal mechanism 7 includes a dust cover 701 located above the fixing frame 3. The dust cover 701 is a bottom opening structure, and the dust cover 701 is made of transparent acrylic material. The four corners of the dust cover 701 are all arc-shaped structures.

[0036] Working principle of the device: When the device is used, the staff places the wooden board on the slide 2, and then drives the wooden board to move on the machine 1 by pushing the slide 2. During the movement, the motor 4 under the fixed frame 3 drives the cutting blade 6 to rotate through the connecting shaft 5. The wooden board can be cut when it contacts the cutting blade 6. In the cutting process, the wooden board will contact the dust cover 701. The dust cover 701 moves to the top surface of the wooden board along the support 12 through the connecting rod 13. The dust and impurities generated during the cutting process are gathered in the dust cover 701. The pump 703 on one side below the fixed frame 3 extracts the dust and impurities in the dust cover 701 through the exhaust pipe 702 and transports them to the collection box 8 for collection. The filter plate 9 in the collection box 8 can prevent dust and impurities from being discharged from the exhaust pipe. While cutting the wooden board, the motor 4 drives the synchronous wheel 1103 and the synchronous belt 1104 to work through the connecting shaft 5.

In addition, the filter plate 9 can be deformed to a certain extent during the extrusion process, so that the dust in the filter holes on the filter plate 9 is discharged, thereby avoiding clogging of the filter plate 9, ensuring the exhaust efficiency, and improving the air intake and dust removal effect. After extrusion, the extrusion seat 1001 can be reset by the pull of the reset spring 1003.
