The air duct box 201 is installed on the dust collector 1, and its rear end opening is communicated with the interior of the dust collector 1. The rear guide slot frame 202, the front guide slot frame 205 and the air inlet plate 206 are arranged in sequence from rear to front, and are fixed together at the front end opening of the air duct box 201 by screws. The front guide slot frame 205 and the rear guide slot frame 202 combine to form a frame structure with an upper guide slot and a lower guide slot, and the upper guide bar 208 and the lower guide bar 209 are installed on the frame structure and cooperate with the upper guide slot and the lower guide slot respectively. The top and bottom of the mobile reversing plate 204 are fixedly connected with the right half of the upper guide bar 208 and the lower guide bar 209 respectively, and the left ends of the upper guide bar 208 and the lower guide bar 209 are also fixedly connected with the guide bar connecting rod 210 respectively. The air cylinder 207 is installed on the air duct box 201, and the guide bar connecting rod 210 is installed on the cylinder rod of the air cylinder 207 through a floating joint 211, and can drive the upper guide bar 208, the lower guide bar 209 and the mobile reversing plate 204 to move left and right along the upper guide slot and the lower guide slot under the action of the air cylinder 207.

[0030] The first dust collecting port 3 and the second dust collecting port 4 are arranged side by side on the air inlet plate 206, and one of the first dust collecting port 3 and the second dust collecting port 4 can be closed by the left and right movement of the mobile reversing plate 204. In combination with Figure 3 and Figure 7 As shown, when the cylinder rod of the air cylinder 207 is not pushed out, the guide bar connecting rod 210 is located at the left side of the frame structure formed by the front guide slot frame 205 and the rear guide slot frame 202, and the mobile reversing plate 204 is located at the rightmost side, closing the second dust collecting port 4, and at this time, the dust collector 1 is started to suck dust from the first dust collecting port 3.

[0032] As shown in the drawings, Figure 2 , Figure 5 and Figure 6 , in order to avoid the air leakage problem caused by the vibration of the dust collector when the first dust collecting port 3 or the second dust collecting port 4 is in the closed state, the center of the front guide groove frame 205 is provided with a partition frame that can be fitted with the edge of the moving reversing plate 204, and two magnetic buffer blocks 212 are arranged on the left side frame of the frame structure composed of the front guide groove frame 205 and the rear guide groove frame 202, and a magnet 213 and a magnet 214 are arranged at the corresponding positions on the right side of the guide strip connecting rod 210 and the left side of the moving reversing plate 204, respectively, which are matched with the magnetic buffer blocks 212. The right side of the guide strip connecting rod 210 and the left side of the moving reversing plate 204 are respectively provided with rubber buffer blocks 215 and rubber buffer blocks 216.

[0033] As shown in the drawings, Figure 5 , during the pushing process of the air cylinder rod, the rubber buffer block 216 of the moving reversing plate 204 first collides with the left side frame of the frame structure, which plays a buffering role, and the magnet 214 and the magnetic buffer block 212 are tightly adsorbed together by the continuous left movement of the moving reversing plate 204, preventing the moving reversing plate 204 from moving due to vibration and causing air leakage from the first dust collecting port 3. Figure 6 As shown in the drawings, , during the retraction process of the air cylinder rod, the rubber buffer block 215 of the guide strip connecting rod 210 first collides with the left side frame of the frame structure, which plays a buffering role, and the magnet 213 and the magnetic buffer block 212 are tightly adsorbed together by the continuous right movement, preventing the moving reversing plate 204 from moving due to vibration and causing air leakage from the first dust collecting port 4.

[0035] When the air cylinder rod needs to be pushed out, the machine tool numerical control system controls the gas source to communicate with the right quick connector 217 of the air cylinder 207, the gas source gas enters the right side of the air cylinder cylinder to provide thrust for the air cylinder, and pushes the air cylinder rod to move left, when the air cylinder rod is pushed to the in-place position, the left magnetic switch 218 triggers, and sends the in-place signal to the machine tool numerical control system, and the numerical control system controls the gas source to be disconnected with the right quick connector 217 after receiving the signal, and the gas source stops providing power to the air cylinder.

[0036] When the air cylinder rod needs to be pushed out, the machine tool numerical control system controls the gas source to communicate with the right quick connector 217 of the air cylinder 207, the gas source gas enters the right side of the air cylinder cylinder to provide thrust for the air cylinder, and pushes the air cylinder rod to move left, when the air cylinder rod is pushed to the in-place position, the left magnetic switch 218 triggers, and sends the in-place signal to the machine tool numerical control system, and the numerical control system controls the gas source to be disconnected with the right quick connector 217 after receiving the signal, and the gas source stops providing power to the air cylinder.
