Description

Technical Field

[0001] The present invention belongs to the technical field of textile cleaning machines, and particularly relates to a self-suction cotton device for a blowing and suction cleaner. Background Art

[0002] During the use of existing textile machines such as spinning frames, a large amount of floating yarns and fiber dust will be generated. The floating yarns and fiber dust will cause yarn defects or breaks, affecting the quality of textile fabrics. For the cleaning machines supporting existing textile machines, whether it is the commonly used belt-type blowing and suction cleaner at home and abroad or the recently emerged intelligent blowing and suction cleaner with electricity, impurities such as floating yarns and fiber dust at the parts to be cleaned of the textile machine are blown outside the machine and fall to the ground by the blowing air pipe led out from the main machine box, and then are collected by the floor suction and other waste discharge systems in the workshop or are sucked into the filter screen in the suction air circuit by the suction air pipe led out from the main machine box of the cleaner and stored and then cleaned. At present, there are mainly two ways to clean sundries: The first is that the filter screen part is in the main machine box of the cleaner. When the cleaner patrols to the head or tail of the textile machine, the floating cotton fluffs and other impurities in the main filter screen box of the machine are sucked away and recycled by the collective cotton picking system; The second is that the filter screen box (i.e., the manual cotton picking box) is in the middle of the suction air pipe. When the impurities fill the filter screen box, they are taken out and recycled by workers. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a self-suction cotton device for a blowing and suction cleaner, aiming to solve the defects of high use and maintenance costs of the cotton suction device, small cotton box storage capacity and large manual input.

The lower space is provided with an air outlet, and a volute fan is arranged in the lower space. Two partition plates are arranged side by side in the upper space, dividing the upper chamber into three chambers: a middle chamber and filter screen chambers arranged on both sides of the middle chamber. The middle chamber is communicated with the filter screen chambers on both sides through ventilation holes arranged on the two partition plates, and the middle chamber is communicated with the lower space. Moreover, the ventilation holes on the partition plates control the connection or closure of the middle chamber and the filter screen chambers on both sides through a damper mechanism. A first filter screen is arranged in the filter screen chambers. The two filter screen chambers are communicated with an air inlet arranged on the machine shell. In addition, three cotton suction holes respectively communicated with the middle chamber and the filter screen chambers and for the cotton picking mechanism to intervene are opened on the machine shell;

The upper part of the cover plate bracket is rotatably mounted with a pressure roller. A linear bearing is also mounted on the housing. The top rod passes through the linear bearing and is connected to one end of the pressure rod. At the same time, the upper end of the top rod is in contact with the cover plate bracket. The middle position of the pressure rod is rotatably connected to the fulcrum seat located in the intermediate cavity. Its lower end is connected to the door panel, which covers the ventilation hole.

[0008] The cotton-collecting mechanism includes a cotton-suction tube, a cotton-collecting box, a cotton-collecting box, and a push rod. The cotton-collecting box is located at one end of the guide rail. Three cotton-suction tubes are arranged side by side on the cotton-collecting box. The middle cotton-suction tube passes through the cotton-collecting box and connects to the second filter screen located in the cotton-collecting box. The cotton-suction tubes on both sides are connected to the cavity of the cotton-collecting box. The cotton-collecting box is connected to the cotton-collecting box through an air return pipe. A push rod is provided on the upper part of the cotton-collecting box for opening the cover plate. The front end of the push rod is an inclined surface for pushing the pressure roller. At the same time, during the cotton-suction process, the push rod pushes the pressure roller to open the cover plate, and the three cotton-suction tubes are inserted into the middle cavity and the filter screen chamber one by one.

[0009] As a further improvement to the invention, the housing is provided with four air inlets, and every two air inlets are connected to a filter chamber.

[0010] As a further improvement to the invention, the cover plate is provided with three caps for sealing the cotton suction holes.

[0011] As a further improvement to the invention, the cotton collection box is provided with a lid that can be rotatably connected and facilitates the removal of the second filter screen.

The door panel 218 cooperates to cover the ventilation hole 207. The cover plate 211 is provided with three hole covers 219 for sealing the cotton suction hole 209.

[0027] The cotton-picking mechanism 30 includes a cotton-suction tube 301, a cotton-picking box 302, a cotton-collecting box 303, and a push rod 304. The cotton-picking box 302 is located at one end of the guide rail 10. Three cotton-suction tubes 301 are arranged side by side on the cotton-picking box 302. The middle cotton-suction tube 301 passes through the cotton-picking box 302 and connects to the second filter screen 306 located in the cotton-collecting box 303. The cotton-suction tubes 301 on both sides communicate with the cavity of the cotton-picking box 302. The cotton-collecting box 303 is connected to the cotton-picking box through an air return pipe 305. 302 is connected, and the upper part of the cotton collection box 302 is provided with a push rod 304 for opening the cover plate 211. The front end of the push rod 304 is an inclined surface 314 for pushing the pressure roller 213. At the same time, during the cotton suction process, the push rod 304 pushes the pressure roller 213 and the cover plate 211 to open, and the three cotton suction tubes 301 are inserted into the intermediate chamber 205 and the filter chamber 206 one by one. In addition, the cotton collection box 303 is provided with a box cover 307 that can be rotatably connected and is convenient for removing the second filter 306.

[0028] Working principle: During the cotton filtration process, the cover plate 211 of the blow-suction cleaning machine 20 is closed and the door plate 218 is opened. The volute fan 203 in the lower space runs, and the air circulates between the intermediate chamber 205 and the filter chamber 206. The cotton enters the filter chamber 206 from the air inlet and exits from the air outlet 202, forming a circulation loop.

[0029] During the cotton suction process, the push rod 304 pushes the pressure roller 213, the cover plate 211 opens, and the cotton suction pipes 301 are inserted into the intermediate chamber 205 and the filter chamber 206 respectively. At the same time, the cover plate bracket 212 rotates, and the upper end presses down the top rod 215. Using the lever principle, the door plate 218 closes, the filter chamber 206 and the intermediate chamber 205 are sealed, the intermediate chamber 205 is connected to the intermediate cotton suction pipe 301, and the cotton suction pipes 301 on both sides are connected to the filter chamber 206. The cotton fibers in the filter chamber 206 enter the cotton collection box 302 through the cotton suction pipes 301 on both sides, and then enter the cotton collection box 303 again. After entering the cotton collection box 303, the cotton fibers are collected in the cotton collection box 303 through the second filter 306. Air enters the intermediate chamber 205 through the intermediate cotton suction pipe 301, and is discharged from the air outlet 202 under the action of the volute fan 203. The collection of cotton fibers is realized by changing the air path.
