Abstract
Description
Technical Field
[0001] This utility model relates to the field of cleaning technology for the air suction box filter screen of a loom, and in particular to a filter screen cleaning device. Background Technology
[0002] Weaving is an essential step in the production of fiberglass cloth. During operation, the loom will start the suction motor to collect the waste yarn and lint generated during the weaving process into the suction box. The lint and dust in the suction box will adhere to the filter screen. The cleanliness of the filter screen will affect the suction power, so the suction box filter screen needs to be cleaned manually and regularly.
[0003] The traditional method for cleaning the suction box filter involves using an air gun to blow lint and dust from the filter surface into the downdraft of the workshop. The negative pressure in the downdraft then draws the lint and dust back into the return air fan. The downdraft and fan are then cleaned manually periodically. This traditional method of cleaning the suction box filter on a loom results in a dirty environment inside the return air duct and requires a significant amount of manpower for regular cleaning, leading to a waste of human resources. Utility Model Content
[0004] The purpose of this invention is to overcome the above-mentioned problems in the existing technology and provide a filter cleaning device.
[0005] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:
[0006] A filter cleaning device, comprising:
[0007] A cleaning box is provided with a guide channel with an opening facing the front of the cleaning box. A main air intake and a secondary air intake are provided at the rear of the guide channel. A transparent baffle for supporting the filter screen is installed at the front of the guide channel.

Detailed Implementation
[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0028] like Figures 1 to 7 As shown, a filter cleaning device includes a cleaning box 1 and a storage box 2, both of which are rectangular parallelepipeds.
[0029] The cleaning box 1 is provided with a guide channel 11 with an opening facing the front of the cleaning box 1. Specifically, the guide channel 11 includes an upper guide plate 111 that slopes downward from front to back, a horizontal lower guide plate 112, two left-right symmetrical outer guide plates 113, two left-right symmetrical inner guide plates 114, and a rear groove plate 115. The outer guide plates 113, inner guide plates 114, and rear groove plate 115 are welded between the upper guide plate 111 and the lower guide plate 112. An inner guide plate 114 is welded between the rear groove plate 115 and each outer guide plate 113.
[0030] The upper guide plate 111 has an inclination angle of 30° to 60°, the inner guide plate 114 and the rear groove plate 115 have an angle of 150° to 165°, and the outer guide plate 113 and the inner guide plate 114 have an angle of 120° to 150°.
[0031] In a preferred embodiment, the upper guide plate 111 has an inclination angle of 45°, the inner guide plate 114 and the rear groove plate 115 have an angle of 165°, and the outer guide plate 113 and the inner guide plate 114 have an angle of 150°.
[0032] The rear of the guide channel 11 is provided with a main air intake 12 and a secondary air intake 13. Specifically, the main air intake 12 is provided on the rear channel plate 115, and the secondary air intake 13 is provided on the inner guide plate 114.
[0033] As a preferred embodiment, there are two auxiliary air intake ports 13, that is, one auxiliary air intake port 13 is provided on each inner guide plate 114.
