Description

Technical Field

[0001] This application relates to the field of cotton opener technology, specifically a pre-treatment cotton opener. Background Technology

[0002] Cotton openers are an important component of textile machinery. Their main function is to open and remove impurities from raw materials. They are used to evenly open and fluff two-dimensional / three-dimensional spiral cotton, PP cotton, doll cotton, and ordinary hollow cotton. A single-pass opening process is sufficient, making them suitable for toy factories, sofa factories, bedding factories, and home textile and garment factories. While loosening the raw cotton into small bundles, it separates fibers from impurities, with the impurity removal process completed by a mechanical impurity removal section.

[0003] An existing patent (publication number: CN218372647U) discloses a cotton opener, belonging to the technical field of cotton opener technology. It includes a cotton inlet channel, a cotton opener mechanism, and a cotton outlet channel. The cotton opener mechanism includes a main cotton opener roller and several auxiliary cotton opener rollers. The auxiliary cotton opener rollers are arranged around the main cotton opener roller along its rotation direction and gradually approach it. The rotation direction of the auxiliary cotton opener rollers is the same as that of the main cotton opener roller. The advantages of this invention are: it can perform multi-stage cotton opening on raw cotton, reducing cotton fiber damage while improving opening quality; and it is equipped with a dust collection drawer to collect impurities from the raw cotton for easy removal.

[0004] Although the device in the aforementioned comparative document solves the problem that cotton openers can usually only open cotton once and cannot open cotton a second or even third time, the device lacks a filtration structure. During the cotton opening process, it cannot remove impurities from the cotton, resulting in a lot of impurities still mixed in the cotton after opening. In order to solve the above problems, a pre-treatment cotton opener is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a pre-treatment cotton opening machine, which has the advantages of ensuring that the cotton fibers after opening still contain many impurities. This solves the problem that during the cotton opening process, the cotton cannot be cleaned of impurities, resulting in the cotton fibers after opening still containing many impurities.

[0006] To achieve the above objectives, this application provides the following technical solution: a pre-treatment cotton opener, comprising a housing, a feed hopper at the top of the housing, a discharge hole on the side of the housing, and a diverting roller structure, a first conveying structure, a second conveying structure, a main cotton opener roller, a first auxiliary cotton opener roller, a second auxiliary cotton opener roller, and a third auxiliary cotton opener roller inside the housing. The first conveying structure and the second conveying structure are respectively disposed on opposite sides of the main cotton opener roller, and the diverting roller structure is disposed at the bottom of the feed hopper.

[0007] The first conveying structure and the second conveying structure are respectively connected to a first conveyor belt and a second conveyor belt. The first conveyor belt and the second conveyor belt are respectively fixedly connected to a first filter screen and a second filter screen. The front of the housing is provided with a first collection groove and a second collection groove. The inner side of the first collection groove and the inner side of the second collection groove are respectively fixedly connected to a first sliding frame and a second sliding frame. The first sliding frame and the second sliding frame are respectively slidably connected to a first collection box and a second collection box. The first conveyor belt and the second conveyor belt are each fixedly connected to two vibrating frames. The top of the vibrating frame is provided with two through holes. The top of the vibrating frame is fixedly connected to a dual-axis motor. The output end of the dual-axis motor is fixedly connected to a rotating rod. The surface of the rotating rod is fixedly connected to multiple cams. The shaft end of the rotating rod is rotatably connected to the inner side of the vibrating frame.

[0008] The above scheme involves setting up a first conveyor belt to transport cotton to the surface of the main cotton-opening roller, and a second conveyor belt with a discharge hole to transport the opened cotton out. Multiple vibrating frames are used; during cotton transport, the dual-axis motors within the vibrating frames rotate the rotating rod and cam, which in turn vibrates the first or second conveyor belt, preventing cotton from accumulating and jamming. Then, impurities in the cotton are filtered through the first or second filter screen, and the filtered impurities fall into the first or second collection box for collection, facilitating impurity removal from the cotton.

[0009] Furthermore, the first auxiliary opening cotton roller, the second auxiliary opening cotton roller, and the third auxiliary opening cotton roller are arranged inside the housing around the main opening cotton roller, and two sets of cotton twisting columns are provided on the surface of the diverting roller structure.

[0010] The above scheme, by setting up a first auxiliary cotton opening roller, a second auxiliary cotton opening roller, and a third auxiliary cotton opening roller, and in conjunction with the drive of the main cotton opening roller, can perform multi-stage cotton opening, which can reduce cotton fiber damage and improve cotton opening quality. By setting up two sets of cotton twisting columns, the diverting roller structure can feed twice after rotating once, which can intermittently feed cotton.

[0011] Furthermore, a first cotton removal plate, a second cotton removal plate, and a third cotton removal plate are fixedly connected inside the housing, with the first cotton removal plate positioned between the diverting roller structure and the first conveying structure.

[0012] The above scheme allows cotton on the surface of the diverting roller structure to be scraped off onto the surface of the first conveyor belt by setting a first cotton removal plate.

[0013] Furthermore, the second cotton removal plate is positioned between the first conveying structure and the main cotton opening roller.

[0014] The above scheme allows cotton to be conveyed to the surface of the main cotton-opening roller by setting a second cotton-removing plate.

[0015] Furthermore, the third cotton removal plate is positioned between the main cotton opening roller and the second conveying structure.

[0016] The above scheme, by setting a third cotton removal plate, can scrape the cotton from the surface of the main cotton roller onto the surface of the second conveyor belt.

[0017] Furthermore, fixed plates are fixedly connected to both sides of the feed hopper, and a rotating rod is tightly nested between the two fixed plates via bearings. A rotating cover is fixedly connected to the surface of the rotating rod, and a handle is fixedly connected to the side of the rotating cover.

[0018] With the above solution, by setting a rotating cover, after the cotton is put into the device, people can put the rotating cover back on the top of the feed hopper. Under the action of the rotating cover, the cotton can be prevented from flowing out of the feed hopper.

[0019] Furthermore, two circular plates are fixedly connected to the surface of the rotating rod, and the two circular plates are respectively arranged on opposite sides of the rotating cover. A torsion spring is sleeved on the surface of the rotating rod, and the two ends of the torsion spring are respectively fixedly connected to the side of the circular plate and the side of the fixed plate.

[0020] The above solution, by setting a torsion spring, allows the rotating cover to close the top of the feed hopper when the device is not in use, thus preventing dust from flowing into the device.

[0021] Furthermore, multiple support rods are fixedly connected to the bottom of the housing.

[0022] By implementing the above solution and installing support rods, the bottom of the equipment can be supported, thereby enhancing the overall structural stability.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] This pre-treatment cotton opening machine uses a first conveyor belt to transport cotton to the surface of the main opening roller. A second conveyor belt, along with a discharge hole, transports the opened cotton out. Multiple vibrating frames are used; during cotton transport, a dual-shaft motor inside the vibrating frame rotates a rotating rod and a cam. The cam vibrates either the first or second conveyor belt, preventing cotton from accumulating and jamming. Then, impurities in the cotton are filtered through a first or second filter screen. The filtered impurities fall into a first or second collection box for collection, facilitating impurity removal from the cotton. Attached Figure Description
