[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] like Figures 1-5 As shown, this utility model discloses a dust removal structure for a twisting machine, which is an improvement on a dust removal device for a twisting machine disclosed in Chinese Patent Publication No. CN205965355U. The purpose is to improve the suction range and flexibility of use. It includes a circulating filter box 1 located on the side of the twisting machine body and a track 2 for guiding the circulating filter box 1. The front and rear side walls of the circulating filter box 1 are respectively provided with an air inlet 3 and an air outlet 4. The top of the circulating filter box 1 is provided with a meandering spray pipe 20. The specific improvement of this dust removal structure is that: an air suction hood 5 is provided on the front side of the circulating filter box 1 below the air inlet 3. The opening 6 of the air suction hood 5 faces forward to facilitate suction. A connecting port 7 is opened in the middle of the top of the air suction hood 5, which communicates with the inner cavity of the air suction hood. The connecting port 7 is connected to the air inlet 3 via a connecting hose 8. The air suction hood 5 is driven to move up and down by a lifting component. During operation, the circulating filter box 1 reciprocates along the track 2. Dust, lint, and other floating debris generated during textile production are drawn in through the suction hood 5, then pass through the connecting hose 8 into the suction port 3, and finally enter the circulating filter box 1. By installing a suction hood connected to the suction port on the front of the circulating filter box, the suction range is increased. Simultaneously, the suction hood can be raised and lowered vertically, facilitating flexible adjustment of the suction height, making it convenient and flexible to use.

[0024] In this embodiment, the lifting assembly includes a vertical lead screw 9 and a pair of vertical guide rails 10 arranged parallel to the left and right sides of the vertical lead screw 9. The vertical lead screw 10 is driven to rotate by a lifting motor 11 vertically disposed below it. A lifting slider 12 is screwed onto the vertical lead screw 9, and the lifting slider 12 is slidably engaged with the pair of vertical guide rails 10. The suction hood 5 is fixedly installed at the front end of the lifting slider 12. During operation, the lifting motor drives the vertical lead screw to rotate, and the vertical lead screw drives the lifting slider to slide up and down along the pair of vertical guide rails. The lifting slider drives the suction hood to move up and down synchronously, so as to adjust the position of the suction hood.

[0025] In this embodiment, a support block 13 is provided at the lower end of the front side of the circulating filter box 1; the lifting motor 11 is installed on the top of the support block 13.

[0026] In this embodiment, in order to increase the suction range, the suction hood 5 is elongated and extends along the traveling direction of the circulating filter box 1.

[0027] In this embodiment, the cross-section of the air intake hood 5 is trapezoidal in shape, with a larger front end and a smaller rear end.

[0028] In this embodiment, a guide plate 14 is fixed between the top and bottom surfaces of the air intake hood 5. The guide plate 14 is inclined with a lower front end and a higher rear end, and its upper end is located behind the connecting port 7. By setting the guide plate, during suction, the airflow entering from the air intake hood flows upward along the guide plate to the connecting port.

[0029] In another embodiment, in order to facilitate silencing during exhaust and reduce exhaust noise, a muffler 15 is connected to the end of the exhaust port 4 away from the circulating filter box 1.

[0030] In another embodiment, the air outlet 4 has a tubular structure and is threadedly connected to the circulating filter box 1. One end of the air outlet 4 extending into the circulating filter box 1 is detachably fitted with a fiber filter cloth 16 to filter the emitted air. Because the air outlet is threadedly connected to the circulating filter box, it is easy to install and remove, and the fiber filter cloth can be easily replaced manually.

[0031] In another embodiment, in order to improve the noise reduction effect, the inner circumferential side of the air outlet 4 is provided with noise-absorbing cotton 17.

[0032] In this embodiment, the lower end of the circulating filter box 1 is connected to a return water pipe 18, which is connected to a spray pipe 20 via a water pump 19. The water pump draws water from the circulating filter box and sprays it out through multiple spray nozzles on the spray pipe. This part of the structure is the same as the dust removal device on a twisting machine disclosed in Chinese Patent Publication No. CN205965355U, and will not be described in detail here.

[0033] It should be noted that this utility model is an improvement on a dust removal device for a twisting machine disclosed in Chinese Patent Publication No. CN205965355U. Other undescribed structures (such as the internal structure of the circulating filter box, filter plate, drain pipe, etc.), suction principle, spraying method, detailed working process, etc. are the same as the dust removal device for a twisting machine disclosed in Chinese Patent Publication No. CN205965355U, and will not be repeated here.

[0034] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then, unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws), or a non-detachable fixed connection (e.g., riveting, welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured using a casting process) (except where it is obviously impossible to use an integral forming process).

[0035] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in this utility model above include states or shapes that are similar to, close to, or approximate with them.
