technical field

The invention relates to the field of textile production, in particular to a cotton wool filtering and collecting device for a cleaning machine.

Background technique

When processing cotton materials, firstly, the impurity dust inside will be stripped by the cleaning machine. Impurities are easy to remove, but in order to ensure the air quality of the working environment during the dust removal process, it is often used to increase the air quality inside the cleaning machine. The dust removal device is used to prevent the dust from spreading, but the existing dust removal equipment is easily affected by the clogging of cotton wool, which greatly reduces the dust handling capacity and the service life of the filter screen, and requires frequent replacement of the filter screen or manual cleaning of the cotton wool on the filter screen, which greatly reduces production efficiency;

The carding machine with the dust removal function disclosed in the publication number CN 110219158 B adopts a brush body that reciprocates up and down to clean the cotton wool on the surface of the dust filter plate, but the cotton wool is easy to fit tightly on the filter plate due to the flat surface of the filter plate. On the surface of the plate or in the filter holes, the brush body is difficult to be brushed off by the cotton wadding attached to the surface of the filter plate, and the lint that is brushed off tends to remain on the brush body, requiring regular cleaning, which is poor in practicability.

A vertical rod 7 is fixed on the right end of the turntable 2, and an arc-shaped plate 8 is fixed on the inner side of the vertical rod 7. The arc-shaped plate 8 is coaxial with the filter cartridge 3. When the arc-shaped plate 8 rotates with the vertical rod 7 to the front side of the filter cartridge 3 At the same time, the arc plate 8 can block the front opening of the filter cartridge 3, and the inner edge of the arc plate 8 is provided with a plurality of blind holes 9 from top to bottom, and each blind hole 9 is located at the interval position of the C-shaped block 5. There is a scraper 10 in each blind hole 5, the scraper 10 can slide axially along the blind hole 5 and the outer end of the scraper 10 is always in contact with the outer edge of the filter cartridge 3;

An air outlet pipe 11 is fixed in the middle of the lower end surface of the filter cartridge 3. The air outlet pipe 11 runs through the lower end surface of the filter cartridge 3 and the housing 1 and is rotatably connected with the turntable 2 through bearings. A first through-hole 12 is provided, a second through-hole 13 coaxial with the first through-hole 12 is provided on the lower surface of the housing 1, and a third through-hole 14 is provided on the turntable 2. When the arc-shaped plate 8 follows the vertical bar 7 When rotating to the front side of the filter cartridge 3, the third through hole 14 is coaxial with the first through hole 12 and the second through hole 13.

The first through hole 12 of the upper end is connected with an air intake pipe 15, the air intake pipe 15 runs through the upper end surface of the housing, the second through hole 13 lower end is connected with an exhaust pipe 16, and a cloth bag 17 is fixed at the lower end of the exhaust pipe 16.

The lower end surface of the housing 1 is fixed with a motor 18. The output shaft of the motor 18 penetrates into the cavity of the housing 1 and is fixedly connected with a gear 19. The outer edge surface of the turntable 2 is a toothed surface and meshes with the gear 19. The motor 18 Can drive the turntable 2 to rotate.

One end of each scraper 10 close to the axis of the filter cartridge 3 is fixed with bristles 20, and the scraper 10 is connected to the bottom of the blind hole 9 through a spring.

The bristles 20 are hard bristles.

The filter cartridge 3 has a certain thickness, and the groove 4 does not penetrate through the inner and outer end surfaces of the filter cartridge 3 .

The C-shaped blocks 5 are arranged at equal intervals, and the scraper 10 is in clearance fit with the adjacent C-shaped blocks 5 .

A plurality of horizontally placed support rods 21 are evenly distributed between the arc-shaped plate 8 and the vertical bar 7 from top to bottom, and the left and right ends of the support bars 21 are respectively fixed on the arc-shaped plate 8 and the vertical bar 7 .

It is worth mentioning that, in order to increase the effective filtering area, the C-shaped block 5 can be set as a material that can be used for filtering, and hard bristles are arranged on the inner edge of the arc-shaped plate 8 to fit the outer edge of the C-shaped block 5 .

When the present invention is in use, firstly, air is blown above the working cavity of the cleaning machine or carding machine through a fan, and the air inlet pipe 15 is connected with the working cavity of the cleaning machine or carding machine, and the air flow carries dust and lint through the trachea 15 enters the cavity of the housing 1, and then the clean gas filtered by the filter cartridge 3 is discharged from the housing 1 through the lower air outlet pipe 11, and the motor 18 is started, and the motor 18 drives the turntable 2 to rotate through the gear 19, and the turntable 2 is supported by the vertical rod 7 and The rod 21 drives the arc-shaped plate 8 to rotate on the outer edge of the C-shaped block 5. When the scraper moves to the position of the groove 4, the bristles 20 at the outer end of the scraper 10 are always in contact with the outer edge of the filter cartridge 3 due to the pressure of the spring on the scraper 10. When the scraper 10 rotates with the arc-shaped plate 8, the bristles 20 scrape and carry the cotton on the outer edge of the filter cartridge 3 and move it until the arc-shaped plate 8 moves to the front opening of the filter cartridge 3. The arc-shaped plate 8 seals the front opening of the filter cartridge 3 and at the same time the third through hole rotating with the turntable 2 communicates with the first through hole 12 and the second through hole 13 on the lower side, and the scraper 10 and the bristles 20 will rotate once The scraped cotton is uniformly scraped to the inside of the U-shaped plate 6, and the airflow entering the air inlet pipe 15 discharges the cotton collected inside the U-shaped plate from the exhaust pipe 16 below to the cloth bag 17, and then the arc-shaped plate 8 and the scraper The plate 10 continues to rotate with the turntable 2, and the scraper 10 restarts a new round of scraping, and finally can carry out unified recycling by taking out the cotton wool collected in the cloth bag 17.

In the present invention, grooves 4 and C-shaped blocks 5 are fixed on the outer edge of the filter cartridge 3, so that the outer edge of the filter cartridge 3 presents a longitudinally and circumferentially concave-convex curved surface, so that the cotton wool blocked on the outside of the filter screen cannot be separated from the filter cartridge 3. The outer edge surface fits together, making it easier for the scraper 10 and the bristles 11 to scrape off the lint outside the filter cartridge 3, greatly improving the self-cleaning effect of the filter cartridge 3, and improving the overall filtration efficiency and service life of the device;

In the present invention, by opening the front side of the filter cartridge 3 and setting a U-shaped plate 6 at the opening position, the arc-shaped plate 8 blocks the front opening of the filter cartridge 3 when the rotating disk 2 rotates to the position of the U-shaped plate 6, and the third through hole 14 With the rotation of the turntable 2 to the coaxial position with the first through hole 12 and the second through hole 13, an independent pipeline is formed, so that the air flow can only be discharged through the exhaust pipe 16, and the scraper 10 is scraped to the U-shaped plate 6 The inner lint can be rushed out into the cloth bag 17 by the air flow, so as to realize the centralized collection of the lint scraped by the scraper 10. When the arc-shaped plate 8 leaves the position of the U-shaped plate 6, the turntable 2 blocks the first through hole on the lower side again. 12. Prevent the collected cotton wool from returning to the material again.
