Description
Technical Field
[0001] This utility model relates to the field of cotton sliver cleaning devices for drawing frames, and more specifically, to a cotton sliver cleaning device for drawing frames. Background Technology
[0002] Cotton is the seed fiber of plants in the genus Gossypium of the Malvaceae family. It originated in subtropical regions. During cotton processing, a drawing frame is used to draw the fibers. The drawing frame is a spinning machine that processes several fibers into a sliver. The function of the drawing frame is to change the internal structure of the sliver, thereby improving its long-segment uniformity and reducing its dimensional inconsistency. It makes the fibers in the sliver straight and parallel, reduces hooks, ensures that the fineness meets the specifications, and mixes different types or qualities of raw materials evenly to achieve the specified mixing ratio. When drawing slivers, the cotton sliver cans are left in the workshop for a long time, which can cause some impurities to adhere to the surface of the cotton slivers. However, current drawing frames cannot clean the impurities attached to the cotton slivers during use. When the cotton slivers and impurities enter the drawing frame together, it affects the drawing effect and can easily damage the drawing frame.
[0003] In traditional technology, such as the authorized announcement number CN218872962U, this utility model relates to the field of cotton drawing technology. This utility model provides a cotton drawing processing device, including a drawing machine and a cotton sliver. The drawing machine is provided with a connecting rod, which is fixedly connected to the drawing machine. The connecting rod is provided with a cleaning component, which includes a fixed frame. This utility model, by setting a fixed frame, a connecting plate, a cleaning brush, screws, a push plate, and a push rod, allows the cotton sliver to pass through the cleaning component before entering the drawing machine for drawing. Under the action of the elastic force of the support spring, the support spring drives the connecting plate to move through the push plate and the push rod. The connecting plate drives the cleaning brush to stick to the cotton sliver. During the process of the cotton sliver entering the drawing machine, the cleaning brush can clean the impurities on the cotton sliver. Thus, the impurities on the cotton sliver can be cleaned during use without affecting the drawing effect of the cotton sliver or damaging the drawing machine.
[0004] Furthermore, in the existing technology, such as the authorized announcement number CN219731176U, this utility model relates to the field of drawing frame technology and discloses a cotton sliver cleaning device for a drawing frame, including a cleaning box fixed at the cotton sliver inlet of the drawing frame. The cleaning box has a cavity inside, and a partition is arranged opposite to each other in the cavity. The partition divides the cavity into a cleaning chamber and a dust suction chamber. Multiple cleaning brushes are arranged on the side of the partition near the cleaning chamber, and a rotating rod is rotatably installed in the dust suction chamber. This utility model, by setting a cleaning box at the cotton sliver inlet of the drawing frame, allows the partition in the cleaning box to work with the brushes to clean cotton lint and other debris on the cotton sliver passing through the cleaning chamber, thereby improving the subsequent drawing effect. The drive motor and the rotating rod, together with the scraping teeth, can scrape off the debris attached to the cleaning brushes. Then, the blower sucks the debris out through the exhaust pipe, which is more time-saving and labor-saving than manual cleaning.
[0005] In the aforementioned patents, one method cleans the dust off the surface of the tampons with a brush, while the other method removes the lint from the brush surface by suction after cleaning the tampons. Both methods have complex mechanisms and low efficiency. Furthermore, cleaning the tampons with a brush directly causes the tampons to become fuzzy and damaged, affecting subsequent processing.

[0025] Example 1
[0026] Please see Figure 1-5 A cotton sliver cleaning device for a drawing frame includes a drawing frame body 1. Positioning wheels 2 are provided on the surface of the drawing frame body 1. A cotton sliver 100 is inserted into the inner surface of the positioning wheels 2. A support base 3 is fixedly connected to the upper surface of the drawing frame body 1. An annular suction shell 4 is fixedly connected to the inner surface of the support base 3. Suction holes 5 and an annular cleaning sponge block 6 are provided on the inner surface of the annular suction shell 4. The inner surface of the annular cleaning sponge block 6 is attached to the outer surface of the cotton sliver 100. A suction cylinder 7 is provided at the outer end of the annular suction shell 4. A turbine fan 8 is fixedly connected to the outer end face of the suction cylinder 7. A collection box 9 is fixedly connected to the outer surface of the outlet of the turbine fan 8. A filter screen 10 is fixed to the inner surface of the collection box 9. The device removes dust by allowing the cotton sliver to pass through the annular suction shell, using the turbine fan to suck up dust from the surface of the cotton sliver, and using the sponge to clean the surface of the cotton sliver. The device is simple in structure and does not damage the cotton sliver.
[0027] The filter screen 10 is obliquely distributed and fixed on the upper inner surface of the collection box 9; when it is venting, dust and air are sprayed out together, and the dust and debris adsorbed by the filter screen 10 are filtered out, which facilitates filtration.
[0028] A hinge shaft 11 is provided on the lower outer surface of the collection box 9, and a flip-top closing cover 12 is hinged to the lower surface of the collection box 9 through the hinge shaft 11; when the collection box 9 is opened, the collected dust can be discharged, and the collection box 9 can be opened by opening the flip-top closing cover 12.
[0029] The flip-top closing cover 12 is fixedly connected to the lower surface of the collection box 9 by bolts 13; the flip-top closing cover 12 is locked and fixed by bolts 13, and the flip-top closing cover 12 can be opened after the bolts 13 are removed.
[0030] The outer surface of the positioning wheel 2 is set with a polished smooth layer; when the cotton strip 100 passes through the positioning wheel 2, the cotton strip 100 can be positioned and dragged, which facilitates positioning, and the smooth surface treatment reduces friction.
[0031] Suction holes 5 are distributed on the inner and outer surfaces of the annular suction shell 4; when the cotton strip 100 passes by, it can evenly and comprehensively suck up the dust on the surface of the cotton strip 100.
[0032] The annular suction shell 4 and the suction cylinder 7 are interconnected, and the outer end of the suction cylinder 7 is fixedly connected to the outer surface of the air inlet of the turbine fan 8; this facilitates the interconnection and suction of dust.
[0033] In use, an annular suction shell 4 is fixedly connected to the inner surface of the support base 3. The inner surface of the annular suction shell 4 is provided with suction holes 5 and an annular cleaning sponge block 6. The inner surface of the annular cleaning sponge block 6 is attached to the outer surface of the cotton strip 100. A suction cylinder 7 is provided at the outer end of the annular suction shell 4, and a turbine fan 8 is fixedly connected to the outer end face of the suction cylinder 7. (A turbine fan is a device that uses a motor to drive an impeller to rotate, generating centrifugal force to compress and transport gas. It features high efficiency and a compact structure. The turbine fan drives the impeller to rotate via a motor, and the blades in the impeller force the gas to rotate, doing work on the gas and increasing its momentum; under the action of centrifugal force, the gas is thrown out.) The impeller converts kinetic energy into pressure energy through the vortex casing. When the gas inside the impeller is discharged, the pressure inside the impeller is lower than the pressure inside the air inlet pipe. New gas is drawn into the impeller under the action of the pressure difference, thereby realizing the continuous discharge of gas (with a large suction force). A collection box 9 is fixedly connected to the outer surface of the air outlet of the turbine fan 8, and a filter screen 10 is fixed to the inner surface of the collection box 9. In use, the cotton strip 100 passes through the annular suction shell 4 and the annular cleaning sponge block 6. The turbine fan 8 draws airflow, and the suction holes 5 in the annular suction shell 4 can draw dust from the surface of the cotton strip 100. The annular cleaning sponge block 6 can clean the surface dust without brushing the cotton strip 100 and causing damage.
[0034] The lower surface of the collection box 9 is hinged to a flip-top closing cover 12 via a hinge shaft 11. When the collection box 9 is opened, the collected dust can be discharged. The collection box 9 can be opened by opening the flip-top closing cover 12. The flip-top closing cover 12 is fixedly connected to the lower surface of the collection box 9 by bolts 13. The flip-top closing cover 12 is locked and fixed by bolts 13. After removing the bolts 13, the flip-top closing cover 12 can be opened, making it easy to take out the collected dust.
