[0020] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0021] Some embodiments of the present invention are described below with reference to the accompanying drawings.

[0022] Example 1:

[0023] Combine Figure 1-3 As shown, this embodiment provides a dust collection air pipe switching device for a cutting machine, including: a main body mechanism 100.

[0024] Among them, the main body mechanism 100 includes an upper tube body 110, a lower tube body 120 arranged below the upper tube body 110, a filter element 130 symmetrically arranged between the upper tube body 110 and the lower tube body 120 and connected to the two, an air delivery member 140 movably arranged in the inner cavity of the upper tube body 110 and the lower tube body 120 and extending outward, a driving member 150 installed on one side of the filter element 130 and fixedly connected to the air delivery members 140 on both sides, a dust exhaust pipe 160 installed in the middle of the upper tube body 110 and connected to the inner cavity of the upper tube body 110, a cleaning pipe 170 installed in the middle of the lower tube body 120 and connected to the inner cavity of the lower tube body 120, and a flow rate sensor 180 installed at the end of the upper tube body 110 corresponding to the air delivery member 140.

[0025] The upper tube body 110 and the lower tube body 120 have the same structure and are used to install the filter element 130 and the air delivery element 140. Two filters 130 are provided, which are located between the upper tube body 110 and the lower tube body 120 and are used to filter the dust-laden gas. The filter element 130 includes a shell 131 arranged between the upper tube body 110 and the lower tube body 120 and a filter cartridge 132 fixed on the inner top wall of the shell 131. The top end of the shell 131 is connected to the inner cavity of the upper tube body 110, and the bottom end is connected to the inner cavity of the lower tube body 120, so that the dust-laden gas is conveniently sent into the inner cavity of the filter cartridge 132 through the air delivery element 140 in the upper tube body 110. After being filtered by the filter cartridge 132, the dust stays in the filter cartridge 132, and the clean air is sent out through the air delivery element 140 in the lower tube body 120.

[0026] The gas delivery component 140 is used to introduce dust-laden gas into the filter element 130 on one side and to discharge the clean gas filtered by the filter element 130. It includes a slider 141 movably arranged in the inner cavity of the upper tube body 110 or the lower tube body 120 and an air pipe 142 fixed at the end of the slider 141 and extending outward. A right-angle flow channel 1411 is opened in the slider 141, and one end of the right angle is connected to the air pipe 142, which is used to introduce the air in the air pipe 142 into the filter element 130 or to facilitate the clean gas in the filter element 130 to enter the air pipe 142.

[0027] The driving member 150 is used to drive the gas delivery member 140 in the upper tube body 110 and the lower tube body 120 to move synchronously to realize the switching of the filter element 130. The driving member 150 includes an electric telescopic rod 151 fixed to the outside of the filter element 130, a connecting rod 152 fixed to the end of the electric telescopic rod 151 and one end of which is fixedly connected to the end of the gas delivery member 140 in the upper tube body 110; and a support rod 153 fixed to the other end of the connecting rod 152 and fixedly connected to the corresponding end of the gas delivery member 140 in the lower tube body 120. When the electric telescopic rod 151 is started, it drives the connecting rod 152 and the support rod 153 to move synchronously, that is, drives the gas delivery member 140 in the upper tube body 110 and the lower tube body 120 to move synchronously to realize the switching of the filter element 130.

[0028] The flow rate sensor 180 is used to monitor the flow rate of the dust-laden gas in the gas transmission component 140 in real time. When the flow rate is lower than a set value, it can be determined that the filter element 130 on this side is clogged and the filter element 130 needs to be switched.

[0029] The dust exhaust pipe 160 is used to discharge the dust entering the upper tube body 110, and the cleaning pipe 170 is used to deliver high-pressure gas into the lower tube body 120, so that the high-pressure gas can pass through the lower tube body 120 into the clogged filter element 130 to backwash the filter cartridge 132 in the filter element 130. The cleaning pipe 170 includes an air intake pipe 171142 fixed in the middle of the lower tube body 120 and connected to the inner cavity of the lower tube body 120, and an electric valve 172 installed on the air intake pipe 171142. The air intake pipe 171142 is used to deliver high-pressure gas into the lower tube body 120, and the electric valve 172 is used to control the opening and closing of the air intake pipe 171142.

[0030] The working principle and use process of the utility model are as follows: when in use, the dust-laden gas is fed in through the gas delivery member 140 in the upper tube body 110, and the dust-laden gas enters the filter element 130 on one side through the air pipe 142 and the right-angle flow channel 1411 in the slider 141. At this time, the dust in the gas is filtered by the filter cartridge 132, and the clean air is discharged through the gas delivery member 140 in the lower tube body 120. When the flow rate sensor 180 detects that the flow rate of the dust-laden gas is lower than the set value, it is determined that the filter cartridge 132 in the filter element 130 is blocked, and the electric telescopic rod 151 is started. The start-up drives the connecting rod 152 and the support rod 153 to move synchronously, that is, drives the air delivery member 140 in the upper tube body 110 and the lower tube body 120 to move synchronously, switches to the filter element 130 on the other side to continue operation, and then opens the electric valve 172. High-speed air is sent into the lower tube body 120 through the air inlet pipe 171142, and then enters the clogged filter element 130 to backwash the filter cartridge 132. The cleaned dust enters the upper tube body 110 and is discharged along the dust exhaust pipe 160, realizing automatic cleaning of the filter element 130. Then the above process can be repeated.

[0031] 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 these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
