[0032] The utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0033] A dustproof device for textile machine frequency converter, which has the structure that can be Figures 1-6 schematically shown. In this embodiment, the dustproof device for textile machine frequency converter comprises a connecting seat 1, a first filter plate 4 and a cleaning assembly, wherein the connecting seat 1 is used to provide a bearing base for other components in the device, the first filter plate 4 is used to filter air and intercept fabric debris entrained in the air, and the cleaning assembly is used to clean the first filter plate 4 to avoid clogging of the first filter plate 4.

[0034] Specifically, a plurality of first filter holes 41 are arranged on the first filter plate 4, a flow guide channel 11 is arranged inside the connecting seat 1, a connecting plate 2 is arranged on the top of the connecting seat 1, the connecting plate 2 is provided with an air outlet cutout 21 that is in communication with the flow guide channel 11, and a bearing plate 3 is further arranged on the bottom surface of the connecting seat 1, and the bearing plate 3 is provided with an air inlet cutout 31 that is in communication with the flow guide channel 11. When assembling, the staff can first detachably install the first filter plate 4 inside the air inlet cutout 31 and ensure that the bottom surface of the first filter plate 4 is flush with the bottom surface of the bearing plate 3, and then install the connecting plate 2 on the air inlet of the frequency converter heat dissipation device through bolts, so that the air outlet cutout 21 is in communication with the air inlet of the heat dissipation device. When in use, the air in the external environment needs to be filtered by the first filter plate 4 to enter the flow guide channel 11, and finally enters the heat dissipation device along the air outlet cutout 21, so as to avoid clogging of the heat dissipation device due to the fabric debris entrained in the air.

[0035] Since the first filter plate 4 can intercept the fabric debris entrained in the air, after the device is used for a period of time, a debris attachment layer will be formed on the first filter plate 4. In order to facilitate cleaning of the debris attachment layer, the cleaning assembly in the device comprises a dust collection box 5 and a cleaning roller brush 6. As Figure 2 and Figure 5As shown, the dust collecting box 5 is slidingly arranged at the bottom of the bearing plate 3, and the dust collecting port is arranged on the top surface of the dust collecting box 5. The cleaning roller brush 6 is rotatably arranged inside the dust collecting port, and the side wall of the cleaning roller brush 6 is in contact with the bottom surface of the bearing plate 3. When the debris adhering layer needs to be cleaned, the staff can drive the dust collecting box 5 to reciprocally slide on the bottom of the bearing plate 3, so that the cleaning roller brush 6 sweeps the bottom surface of the first filter plate 4. During the sweeping process, the debris adhering layer will be separated from the first filter plate 4 and collected inside the dust collecting box 5, ensuring that the air in the external environment smoothly enters the inside of the device.

[0036] In addition, since the common fabric debris generally contains long threads and fabric fibers, the threads and fabric fibers are easy to wind around the outside of the cleaning roller brush 6 during the sweeping process of the cleaning roller brush 6, thereby affecting the sweeping effect of the cleaning roller brush 6. To solve this problem, the cleaning assembly further includes a cleaning rod 7, which should be arranged inside the dust collecting box 5 and parallel to the cleaning roller brush 6. A dust collecting channel is formed between the cleaning rod 7 and the inner side wall of the dust collecting box 5. A plurality of cleaning strips 71 are arranged on the side wall of the cleaning rod 7 close to the cleaning roller brush 6, and a plurality of cleaning ring grooves 61 are arranged on the cleaning roller brush 6 for accommodating the cleaning strips 71.

[0037] When the cleaning roller brush 6 rotates due to the sliding of the dust collecting box 5, the cooperation of the cleaning strips 71 and the cleaning ring grooves 61 can make the threads and fabric fibers wound around the outside of the cleaning roller brush 6 fall off, so as to ensure that the cleaning roller brush 6 always has good sweeping effect. At the same time, since the dust collecting channel exists between the cleaning rod 7 and the inner side wall of the dust collecting box 5, when the fabric debris is separated from the cleaning roller brush 6, it can move along the dust collecting channel to the bottom of the dust collecting box 5, thereby avoiding the debris in the dust collecting box 5 from splashing outward due to the rotation of the cleaning roller brush 6.

[0038] As an optional embodiment of the present embodiment, the cleaning rod 7 in the device has two, and the two cleaning rods 7 should be located on the two sides of the cleaning roller brush 6, so as to facilitate the cleaning of the cleaning roller brush 6 with different rotating directions. In addition, one end of the cleaning strip 71 close to the cleaning roller brush 6 should be higher than the other end close to the cleaning rod 7, so as to guide the debris separated from the cleaning roller brush 6 by the inclination of the cleaning strip 71, and facilitate the movement of the debris along the dust collecting channel to the bottom of the dust collecting box 5.

[0039] In addition, to facilitate the cleaning of the debris collected inside the dust collecting box 5, a sweeping port can be arranged on the bottom surface of the dust collecting box 5, and a detachable sweeping baffle 53 is arranged inside the sweeping port. The staff can periodically remove the sweeping baffle 53, so as to move the debris accumulated inside the dust collecting box 5 out of the dust collecting box 5 along the sweeping port.

[0040] In order to realize the sliding connection between the dust collecting box 5 and the bearing plate 3, two connecting rods 51 can be arranged on the top surface of the dust collecting box 5, and the two connecting rods 51 are located on both sides of the dust collecting port, and two guide cutouts 32 for accommodating the connecting rods 51 are arranged on the bearing plate 3, so that the sliding of the dust collecting box 5 is guided and constrained by the cooperation of the guide cutouts 32 and the connecting rods 51. In addition, the top end of the connecting rod 51 can also be provided with a limiting piece 52, and a spring 81 should also be arranged on the connecting rod 51. After assembly is completed, the limiting piece 52 should be located above the bearing plate 3, and the spring 81 should be located between the limiting piece 52 and the bearing plate 3. The elastic force generated by the spring 81 can make the side wall of the cleaning roller brush 6 tightly adhere to the bottom surface of the first filter plate 4, so that the cleaning assembly obtains better cleaning effect.

[0041] Optionally, in order to reduce the difficulty of the staff driving the dust collecting box 5 to slide, a contact ring 82 can also be arranged on the connecting rod 51, and the contact ring 82 should be arranged between the spring 81 and the bearing plate 3. As shown in Figure 6 The bottom surface of the contact ring 82 can be provided with rolling beads 821, which can reduce the movement resistance of the dust collecting box 5 and improve the operation convenience of the device when the staff drives the dust collecting box 5 to slide.

[0042] As another optional embodiment of the embodiment, in order to facilitate the staff to apply force to the dust collecting box 5, an operation strip 54 can be arranged on the side wall of the dust collecting box 5, so as to improve the gripping reliability of the dust collecting box 5 by means of the operation strip 54.

[0043] In actual work process, due to the difference in particle size of fabric debris, in order to improve the filtering effect of the device on fabric debris, the dustproof device for textile machine frequency converter can also include a second filter plate 9 in the embodiment. Specifically, the second filter plate 9 is detachably arranged inside the air outlet cutout 21, a plurality of second filter holes 91 are arranged on the second filter plate 9, the aperture of the second filter hole 91 is smaller than the aperture of the first filter hole 41, and the second filter hole 91 is arranged in a staggered manner with the first filter hole 41. By arranging the second filter plate 9, the air leaving the flow guide channel 11 can be filtered again, so as to intercept small particle size fabric debris in the air, thereby further improving the dustproof filtering effect of the device.

[0044] In addition, in order to avoid that the air in the external environment enters the heat dissipation equipment through the joint gap between the device and the heat dissipation equipment, a sealing ring groove 22 can also be arranged on the top surface of the connecting plate 2, and a sealing strip 221 is arranged in the sealing ring groove 22, so as to block the joint gap by means of the sealing strip 221.

[0045] The effect of the above scheme is described as follows:

[0046] The embodiment provides a dustproof device for a textile machine frequency converter, which can clean the first filter plate through a cleaning assembly, so that the first filter plate is prevented from being blocked.

[0047] The above merely describes preferred embodiments of the utility model and is not intended to limit the utility model, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
