[ background of the invention ]

In the cotton spinning production process, the carding machine is used for opening, uniformly mixing, carding and removing impurities from raw materials such as cotton rolls or raw cotton layers conveyed in the previous process, and finally bundling into cotton slivers which are regularly stored in a sliver can for the subsequent process.

The carding function of the carding machine is mainly realized by three parts:

the first part consists of a cotton feeding structure and a licker-in structure, and is characterized in that the licker-in is held and combed to realize carding and impurity removal;

the second part consists of a cylinder structure, a movable cover plate structure and a doffer structure, and fine carding, straightening and uniform mixing are realized by taking fine carding of the cylinder and the movable cover plate as characteristics;

the third part is the output part of the carding machine and consists of a three-roller structure, a bundling and sliver forming structure and a coiler structure.

In the second part of the carding machine, cotton flock adhered to floccules is collected on the movable cover plate in the working process, which is one of key factors directly influencing the carding quality of the carding machine. After careful observation, research and analysis, the flocculent cotton linters gathered and adhered on the movable cover plate are both floating type and winding type, and a cleaning device is required to be arranged on the movable cover plate to remove the applique on the movable cover plate in order to improve the carding quality of the carding machine. The traditional cleaning device has the working structure and the principle that: the cleaning device is composed of a brush roller and a cleaning roller, when the cover plate slowly rotates and circularly moves forwards from back through a synchronous belt, the cover plate is cleaned by the brush roller, the brush roller is cleaned by the cleaning roller, and the cleaned short fibers are cleaned away through an air suction pipeline. However, the scheme can only remove part of floating cotton linters, the cleaning of the winding cotton linters is incomplete, the machine is stopped periodically and the cotton linters are manually removed, and the efficiency is low.

[ summary of the invention ]

The invention provides a bidirectional cotton cleaning device for a movable cover plate of a carding machine, which can thoroughly clean floating cotton linters and winding cotton linters which are gathered and adhered to the movable cover plate.

The technical scheme adopted by the invention is as follows:

As an advantageous development of the invention, the steel needles of the blowing clothing wrapped around the primary brush roller are distributed uniformly in the radial direction thereof.

As an optimized scheme of the invention, the steel needles of the blowing card clothing wrapped on the primary brush roller are uniformly distributed in the spiral direction, and the spiral distribution direction of the steel needles is opposite to the spiral distribution direction of the steel needles wrapped on the outer surface of the secondary brush roller.

As an optimized scheme of the invention, card clothing distributed in the left spiral direction is wrapped on the secondary brush roller.

As an optimized scheme of the invention, card clothing with steel needles distributed in the right spiral direction is wrapped on the outer surface of the secondary brush roller.

As an optimized scheme of the invention, card clothing with steel needles distributed in the left spiral direction and card clothing with steel needles distributed in the right spiral direction are respectively wrapped on the outer surface of the secondary brush roller along the middle position.

As an optimized scheme of the invention, the outer surface of the primary brush roller is wrapped with card clothing of which the steel needles are distributed in the left spiral direction, and the outer surface of the secondary brush roller is wrapped with card clothing of which the steel needles are distributed in the right spiral direction.

The advantages of the invention are:

the primary brush roller can realize carrying out the radial blowing for the first time to the card clothing on the removable cover, clear away most unsteady type cotton linter promptly, the second grade brush roller can carry out the radial blowing for the second time to the card clothing on the removable cover, can more thoroughly clear away and remain unsteady type cotton linter, can carry out the axial blowing again to the card clothing on the removable cover, be about to twine cotton linter on the removable cover and clear away along the axle, if set up the card clothing of left spiral distribution and the card clothing of right spiral distribution respectively along the centre on the second grade brush roller, the cotton linter of twining on the removable cover then can be driven by the second grade brush roller and clear away the discharge to both sides along the axial. The cotton cleaning device with the structure can clean floating cotton linters and winding cotton linters, has a more thorough cleaning effect, can better ensure the careful carding function of the movable cover plate, and has a good practical operation effect.

[ detailed description ] embodiments

The invention will be further explained with reference to the drawings.

Example 1: a bidirectional blowing device for a movable cover plate of a carding machine is shown in figure 1 and comprises a primary brush roller 1, a secondary brush roller 2, a cleaning roller 3 and a movable cover plate 4, wherein card clothing with steel needles uniformly distributed along the radial direction is wrapped on the outer surface of the cleaning roller 3; the outer surface of the primary brush roller 1 is wrapped with card clothing with steel needles distributed uniformly along the radial direction of the primary brush roller, the outer surface of the secondary brush roller 2 is wrapped with card clothing with the steel needles distributed in the right spiral direction, the primary brush roller 1, the secondary brush roller 2 and the cleaning roller 3 are connected to the movable cover plate 4 through mounting plates and supports, and the steel needles of the card clothing on the primary brush roller 1 and the secondary brush roller 2 are in mutual insertion type contact with the card clothing steel needles on the movable cover plate 4.

Example 2: the difference from the embodiment 1 is that: and the second-stage brush roller 2 is wrapped with card clothing distributed in the left spiral direction.

Example 3: the difference from the embodiment 1 is that: the outer surface of the second-level brush roller 2 is respectively wrapped with card clothing distributed according to the left spiral direction and card clothing distributed according to the left spiral direction along the middle position.

Example 4: the difference from the embodiment 1 is that: the card clothing wrapped on the outer surface of the primary brush roller 1 is distributed in the left-handed spiral direction, and the card clothing distributed in the right-handed spiral direction is wrapped on the outer surface of the secondary brush roller 2.

In the four embodiments, the primary brush roller 1, the secondary brush roller 2 and the cleaning roller 3 are mounted on the movable cover plate 4 through mounting plates and brackets, and the primary brush roller 1, the secondary brush roller 2 and the cleaning roller 3 are all rotated around the central shaft of the primary brush roller 1, the secondary brush roller 2 and the cleaning roller 3 in a fixed-axis manner, wherein the rotating direction is shown in fig. 1. The flap 4 is moved in a cycle in a counter-clockwise direction, as shown in figure 1. The outer surface of the primary brush roller 1 is wrapped with card clothing distributed along the radial direction, and the card clothing is used for removing part of floating type short fibers attached to the movable cover plate 4, as shown in fig. 2. The cleaning roller 3 is wrapped with radial distributed card clothing on the outer surface and is used for removing short hairs scraped from the card clothing on the surface of the movable cover plate 4 on the primary brush roller 1, as shown in figure 3. The short fibers scraped by the cleaning roller 3 are discharged through an air suction pipeline arranged at the end side of the movable cover plate 4.
