It should be noted that these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art. The present disclosure can be implemented in various forms and should not be limited by the embodiments described herein.

[0024] Example 1

[0025] See also Figure 1 and Figure 2 A switching dust removal device for a cutting machine in this embodiment 1 includes: a dust removal duct 1, which is arranged around the inner side of a cutting platform and has a plurality of square first openings on the inner side, and the first openings are connected to a dust suction part 2 on the outside; the dust suction part 2 includes a baffle 201, and a second opening adapted to the first opening is provided on the baffle 201; the baffle 201 is connected to a sandwich plate 202 and a fixed plate 204 in sequence on the side away from the first opening, a movable plate 203 is movably inserted in the sandwich plate 202, and a third opening is provided on the fixed plate 204, and the movable plate 203 is connected to a pumping unit 205, which can control the opening and closing of the third opening on the fixed plate 204 and the first opening on the baffle 201; a dust collecting plate group 3 is arranged at the lower part of the cutting platform and connected to the dust suction part 2, and the dust suction part 2 absorbs dust on the dust collecting plate group 3.

[0026] The dust removal duct 1 is a square duct, and the first opening is a square opening. Compared with a circular tube, a square tube is better for fixing other structures on the surface. A circular tube has to take into account the sliding of the surface structure and is difficult to install. The square opening is on one side of the dust removal duct 1, which can absorb dust with maximum efficiency. Compared with a circular opening, the utilization rate of the first opening is improved.

[0027] The second opening on one side of the baffle 201 is a square opening, and the other side is equipped with a pumping unit 205; the second opening of the baffle 201 has the same shape and size as the first opening, which can better adapt to the whole.

[0028] The sandwich plate 202 is a U-shaped structure with one side open. Figure 5 , the opening faces the side of the pulling unit 205, and a movable plate 203 is arranged inside. The movable plate 203 has the same thickness as the sandwich plate 202, and includes a shielding plate and a connecting portion, the connecting portion is connected to the pulling unit 205, and the shielding plate is inserted in the opening of the sandwich plate 202, and can overlap with the third opening position when the pulling unit 205 is pulled, so as to control the opening and closing of the dust suction part 2.

[0029] The third openings of the fixed plate 204 are a plurality of square openings, the width of the third openings is equal to the spacing between two adjacent third openings, and the total size is not greater than the size of the second openings. The shielding plate of the movable plate 203 is provided with fourth openings of the same shape and number as the third openings. When in use, when the movable plate 203 is only pulled by a fourth opening width, the third opening and the fourth opening can be aligned to achieve the dust removal function, save the pulling distance, shorten the working time of the pulling unit 205, and improve the efficiency. At the same time, the plate is maximized, and the effect is better than other openings such as circular shapes; when it is necessary to stop, the shielding plate can be fully inserted into the sandwich plate 202 to turn off the dust removal function of the dust suction part 2.

[0030] Furthermore, under the same negative pressure source condition, by controlling the overlapping area of ​​the third opening and the fourth opening, the dust suction capacity of the dust suction part 2 can be effectively adjusted. The smaller the overlapping area, the stronger the dust suction capacity of the dust suction part 2 is, so as to cope with different processing environments respectively.

[0031] The outer edges of the fixed plate 204, the sandwich plate 202 and the baffle plate 201 away from the pumping unit overlap. During the production process, the design of edge overlap facilitates unified cutting for the next step of processing, improves processing efficiency, and combines Figure 6 Screw holes are provided at the four corners of the three, and the positions of the screw holes cooperate with each other. They can be connected layer by layer through studs and then fixed on the dust removal duct 1. The fixed plate 204, the sandwich plate 202 and the baffle 201 are arranged in an overlapping manner as a whole, and the height is greater than the opening height of the dust removal duct 1, ensuring that the purpose of opening and closing the dust removal part can be achieved.

[0032] The pumping unit 205 is in the form of a cylinder, which has a small size and high efficiency. It can maintain stable output during rapid start and rapid stop, has good adaptability, and does not generate sparks or overheating in actual applications. It is very suitable for pumping the movable plate 203.

[0033] The dust collecting part 2 also includes: a heat insulation board 206, and the pumping unit 205 is covered with a heat insulation board 206 on the side away from the dust removal pipe 1 and the upper part. Figure 3 and Figure 4 The temperature of the newly processed dust is extremely high, which can easily damage the pumping unit 205. The heat insulation plate 206 protects the pumping unit 205 from being burned. The heat insulation plate 206 is arranged on the movement route of the pumping unit 205 to protect the pumping unit 205 from contacting the dust.

[0034] The dust removal pipeline 1 is arranged in a U-shaped pattern, the dust collection part 2 is arranged symmetrically on both sides of the length direction of the dust removal pipeline 1, and the dust receiving plate group 3 includes a horizontal plate and two inclined plates. Figure 7 The two inclined plates are symmetrically arranged in a V shape on both sides of the dust collection part 2, and the two ends are connected to the dust collection pipe 1 respectively, and the bottom is connected to the horizontal plate, and the horizontal plate is flush with the bottom of the dust collection pipe 1. It is used to receive the dust falling from the cutting platform and improve the dust collection efficiency of the dust collection part 2.

[0035] To facilitate the installation and fixation of the dust collecting plate group 3, horizontally arranged square tubes are respectively provided on both sides of the dust suction part 2, and fifth openings are respectively opened on both sides of the inclined plate. The length of the fifth opening is greater than the height of the square tube. The fifth opening of the inclined plate is inserted into the square tube, and the inclined plate can be fixed at a preset angle, which is convenient for installation.

[0036] An external pipe joint is connected to the dust removal pipe 1, an opening of the dust removal pipe 1 covered by the pipe joint, the other side of the pipe joint is externally connected to a negative pressure source, and an opening is arranged at the part where the dust removal pipe 1 and the pipe joint overlap, so as to provide dust removal power for the whole device.

[0037] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or additions, subtractions or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
