Description

Technical Field

[0001] This utility model relates to the field of drawing frame technology, and in particular to a cleaning device for a drawing frame. Background Technology

[0002] The function of a drawing frame is to improve the internal structure of the sliver, thereby increasing the uniformity of its long segments and reducing the weight unevenness, so that the sliver meets the specifications. During the operation of the drawing frame, a large amount of cotton wool and other impurities will adhere to the drawing rollers during the rolling process, which will affect the quality of the sliver. At the same time, cotton wool and other impurities can easily fill the workshop and cause environmental pollution. Therefore, a drawing frame cleaning device is needed to clean the drawing rollers.

[0003] A search revealed that publication number CN216192975U discloses a suction device for cleaning cotton lint from a drawing frame. The device includes a drawing frame body with multiple compression rollers rotatably connected within it. The drawing frame body also contains a cotton-adhesive roller covered with an adhesive plate. The suction device body is also mounted on the drawing frame body, and has an air inlet pipe. A fixed plate is fixedly connected to the air inlet pipe via multiple support rods. A drive device is fixedly connected to the fixed plate, and a rotating rod is fixedly connected to the output end of the drive device. The advantage of this invention is that the drive device and bevel gear structure can drive a short rod to rotate, thereby using a cleaning brush on the short rod to remove cotton lint from the adhesive plate. This ensures the cleanliness of the adhesive plate, allowing it to clean the cotton lint from the compression rollers, keeping the compression rollers clean, preventing cotton lint accumulation on the compression rollers, and ensuring the cleanliness of the cotton sliver.

[0004] However, the suction device in this solution can only clean one side of the tampons, resulting in incomplete removal of impurities such as lint, which leads to poor tampon cleanliness.

[0005] To address this, a cleaning device for a drawing frame is proposed, which has the advantage of cleaning both sides of the sliver, thereby solving the problems mentioned in the background technology. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cleaning device for a drawing frame.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a cleaning device for a drawing frame, comprising a drawing frame housing, wherein a plurality of upper rollers are installed on the upper part of the inner side of the drawing frame housing, and a plurality of lower rollers are installed on the lower part of the inner side of the drawing frame housing; a sliver is conveyed between the plurality of upper rollers and the plurality of lower rollers; an upper impurity removal component is fixed above the upper rollers, and an upper adsorption tube is provided above the upper impurity removal component; a lower impurity removal component is fixed below the lower rollers, and a lower adsorption tube is provided below the lower impurity removal component; a communication is established between the upper impurity removal component and the upper adsorption tube. A connecting pipe group is provided, and another connecting pipe group is connected between the lower impurity removal component and the lower adsorption pipe. Several unit adsorption hoods are respectively provided on the facing surfaces of the upper and lower impurity removal components, and a scraping component is fixed in each unit adsorption hood. The scraping component is equipped with a brush and a scraper, and the brush and scraper are in contact with the upper or lower roller. A collection box is fixed on the outer wall of the drawing frame housing, and a dust extraction fan is installed on the top of the collection box. A filter screen is installed between the collection box and the dust extraction fan. The upper adsorption pipe and the lower adsorption pipe are connected to the side of the collection box through a tee and a short pipe.

[0008] As a further description of the above technical solution: the lower surface of the collection box is provided with a discharge port, and a U-shaped guide frame welded to the outer wall of the discharge port is welded around the discharge port. A sealing plate in contact with the discharge port is provided on the inner side of the U-shaped guide frame, and guide strips that are slidably connected to the U-shaped guide frame are welded on the left and right sides of the sealing plate.

[0009] As a further description of the above technical solution: the connecting pipe group is composed of two symmetrically arranged F-shaped pipes, and the two F-shaped pipes facing each other are connected to the upper adsorption pipe and the lower adsorption pipe, respectively.

[0010] As a further description of the above technical solution: the scraping assembly is composed of a mounting plate and a scraper and a brush that are inclinedly arranged on the mounting plate, and the mounting plate of the scraping assembly is fixedly connected to the inner side of the upper or lower cleaning assembly by screws.

[0011] As a further description of the above technical solution: the suction pipe of the vacuum fan is provided with a connecting cover, and the connecting cover is correspondingly set with the filter screen of the collection box.

[0012] As a further description of the above technical solution: the multiple unit adsorption hoods of the upper and lower impurity removal components are respectively matched with the number of the upper and lower rollers.

[0013] This utility model has the following beneficial effects:

[0014] In this invention, an upper impurity removal component, a lower impurity removal component, an upper adsorption pipe, a lower adsorption pipe, and a connecting pipe assembly are installed inside the drawing frame housing corresponding to the upper and lower rollers. As the dust extraction fan at the top of the collection box operates, the negative pressure collection box absorbs cotton lint and impurities from the upper and lower rollers through the upper impurity removal component, the lower impurity removal component, the upper adsorption pipe, the lower adsorption pipe, and the connecting pipe assembly. At this time, since several adsorption hoods of the upper and lower impurity removal components are equipped with scraping components with brushes and scrapers, during the rotation of the upper and lower rollers, the brushes and scrapers inclined inside the scraping components clean the cotton lint and impurities on the surface of the upper and lower rollers by wiping and scraping. Compared with the prior art, this invention not only satisfies the double-sided cleaning of cotton slivers but also has the advantage of one-to-one cleaning of the upper and lower rollers, avoiding the problem of incomplete cleaning of cotton lint and impurities causing poor cotton sliver cleanliness.

[0024] In one embodiment, a discharge port 10 is provided on the lower surface of the collection box 9, and a U-shaped guide frame 11 welded to the outer wall of the discharge port 10 is welded to the periphery of the discharge port 10.

When cleaning the collection box 9, the sealing plate 12 inside the U-shaped guide frame 11 is pushed upward to make the sealing plate 12 disengage from the state of blocking the discharge port 10, so that the cotton lint and impurities inside the collection box 9 can be easily removed manually.

[0025] In one embodiment, the connecting pipe group 8 is composed of two symmetrically arranged F-shaped pipes, and the two F-shaped pipes of the connecting pipe group 8 are respectively connected to the upper adsorption pipe 6 and the lower adsorption pipe 7.

[0029] Working principle:

[0030] In use, the cotton sliver is first fed between the upper roller 2 and the lower roller 3 of the drawing frame housing 1. When a large amount of cotton lint and impurities adhere to the surfaces of the upper roller 2 and the lower roller 3, the dust extraction fan 13 at the top of the collection box 9 operates, causing the air inside the collection box 9 to be drawn out by the filter screen 14 through the pipe at the suction port of the dust extraction fan 13. This creates a negative pressure state in the collection box 9, which then absorbs the cotton lint and impurities from the upper roller 2 and the lower roller 3 through the upper impurity removal component 4, the lower impurity removal component 5, the upper adsorption pipe 6, the lower adsorption pipe 7, and the connecting pipe group 8. At this time, since several adsorption hoods of the upper impurity removal component 4 and the lower impurity removal component 5 are equipped with brushes 16 and... During the rotation of the upper roller 2 and the lower roller 3, the scraping component 15 of the scraper 17, with its inclined brush 16 and scraper 17, cleans the cotton lint and impurities on the surface of the upper roller 2 and the lower roller 3 by wiping and scraping. The cotton lint and impurities that have detached from the upper roller 2 and the lower roller 3 are then sucked into the collection box 9 by the suction pipe consisting of the upper impurity removal component 4, the lower impurity removal component 5, the upper suction pipe 6, the lower suction pipe 7, and the connecting pipe group 8. When cleaning the collection box 9, the sealing plate 12 inside the U-shaped guide frame 11 is pushed upward to disengage from the state of blocking the discharge port 10, and then the cotton lint and impurities in the collection box 9 can be manually removed.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
