Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery and equipment, in particular to a carding machine for polyester-cotton yarn which is easy to maintain. Background Art

[0002] When processing polyester-cotton yarn, traditional carding machines often experience filter clogging due to the high levels of impurities and lint in the raw material. This requires frequent machine downtime for cleaning, impacting production efficiency and product quality. While some automatic cleaning devices exist, many suffer from issues such as incomplete cleaning and complex maintenance. Therefore, developing an efficient, automatic, and easy-to-maintain self-cleaning carding machine with a filter is crucial.

[0003] After searching, the Chinese patent with publication number CN221588785U discloses a cotton carding machine with a dust removal function, and its technical points are: it includes a cotton carding machine body, a suction pump and a dust removal device, the upper end of the cotton carding machine body is fixedly connected to a suction pipe, and the right side of the suction pipe is fixedly connected to the suction pump, the upper right side of the suction pipe is snap-connected to the dust removal device, and a dust-proof net is slidably connected to the dust removal device, the top right end of the cotton carding machine body is snap-connected to a collecting box, and the front and rear ends of the inner side of the collecting box are fixedly connected to a handle, the dust removal device is composed of a top plate, a motor, a first gear, a second gear, a scraper and a connecting rod, the middle part of the top of the top plate is fixedly connected to the motor, and the output shaft of the motor is fixedly connected to the first gear, and the right side of the bottom end of the first gear is meshedly connected to the second gear.

[0004] The carding machine with the dust removal function is convenient for disassembling the dust-proof net and the dust removal device, and is convenient for cleaning the dust-proof net to prevent clogging of the dust-proof net.

[0005] However, when the dust screen is clogged, this technology can only be cleaned by stopping the machine and removing the dust screen. Stopping the machine to clean the dust screen will seriously affect production, so a new solution is needed to solve this problem. Utility Model Content

[0006] In view of the above background technology, the prior art has the disadvantages and defects of requiring the machine to be shut down for filter cleaning.

[0007] The utility model discloses an easy-to-maintain carding machine for polyester-cotton yarn, comprising a housing having a hollow structure and a working chamber disposed therein. The working chamber is provided with a pre-combing mechanism, a cylinder, a cover plate, a doffer, a dust removal mechanism, a cleaning mechanism, and a strip forming mechanism. A feed port is disposed at the top of the housing and is in communication with the working chamber. The working chamber comprises a pre-combing chamber, a cylinder chamber, and a doffer chamber. The pre-combing chamber is in communication with the cylinder chamber, which is in communication with the doffer chamber, and the doffer chamber is connected to the strip forming mechanism. Both the cylinder chamber and the doffer chamber are cylindrical cavities, each coaxially provided with a cylinder and a doffer. The dust removal mechanism is disposed in the wall of the doffer chamber. The wall of the cylinder chamber is provided with a filter assembly receiving groove. After the pre-combing chamber completes preliminary combing of the material, the material is further combed by the cylinder, which cooperates with the cover plate to finely comb the material and remove short fibers and impurities. The dust removal mechanism then adsorbs the short fibers and impurities onto the surface of the filter screen. The doffer condenses the fiber layer of the material, further combs and mixes the material, and then transports it to the sliver forming mechanism, which collects the cotton web into slivers and presses them tightly, and outputs the slivers regularly.

[0008] Furthermore, the dust removal mechanism includes a first suction filtration unit and a second suction filtration unit of identical structure. The first suction filtration unit includes a first curved filter screen disposed on the wall of the cylinder chamber, the curvature of the first curved filter screen being adapted to the curvature of the cylinder chamber. A first suction hood is adapted to be disposed on the outer ring of the first curved filter screen, which is connected to a first suction pipe, and a first suction fan is disposed within the first suction pipe. The negative pressure generated by the suction fan causes the air containing impurities in the cylinder chamber to be filtered through the first curved filter screen and discharged to the outside of the housing.

[0009] Furthermore, the second filtration unit has the same structure as the first filtration unit, including a second curved filter screen, a second suction hood, a second suction pipe, and a second suction fan. The first and second curved filter screens are coaxially arranged, and the upper side of the first curved filter screen is aligned with the lower side of the second curved filter screen. The lower side of the first curved filter screen is aligned with the lower side of the filter assembly receiving tank, and the upper side of the second curved filter screen is aligned with the upper side of the filter assembly receiving tank. This alignment prevents leakage of impurity-laden air.

[0010] Furthermore, the cleaning mechanism includes a cleaning cover disposed on the inner wall of the cylinder chamber, the cleaning cover having a fan-shaped structure; the outer arc of the cleaning cover matches the inner wall arcs of the first and second curved filter screens and is slidably connected thereto; a slag discharge channel is formed axially through the cleaning cover, and slag suction holes are formed circumferentially on the curved surface of the cleaning cover, the slag discharge channel and the slag suction holes being in communication; the slag discharge channel is connected to the exterior of the housing, facilitating the discharge of impurities.

[0011] Furthermore, a sliding groove is provided on the outside of the shell, and the specifications of the sliding groove are adapted to the size and movement path of the cleaning cover.

[0012] Furthermore, both front and rear end surfaces of the cleaning cover are provided with sliding cover plates; the sliding cover plates are slidably connected to the outside of the shell; and the end surface of the sliding cover plates is larger than the groove surface of the sliding groove.

[0013] Furthermore, the cleaning cover drive assembly includes a gear ring arranged on the outer ring of the sliding cover and a first gear meshing with the gear ring; the first gear is coaxially fixed on the output shaft of the first drive motor; and the first drive motor is fixed on the outer surface of the shell.

[0014] Furthermore, both end surfaces of the cleaning cover are provided with threaded openings, which are both communicated with the slag discharge channel and are convenient for connecting an external dust removal bag.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. The utility model is provided with a dust removal mechanism, which can remove impurities in the material when the carding machine is working, and can also prevent the material from being sucked out of the equipment, thereby avoiding waste of material.

[0017] 2. The utility model is provided with a cleaning mechanism, which can clean the dust removal mechanism in the equipment without stopping the machine, thereby improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
