Abstract
Description
Technical Field
[0001] This utility model relates to the field of cotton opening technology, specifically a step-by-step cotton opening device. Background Technology
[0002] A cotton opening device is a mechanical device used to loosen compressed or tangled fiber raw materials and remove impurities. Its main function is to loosen compressed cotton, making the cotton clumps smaller and looser, removing some impurities, and making the cotton into a more loose and uniform state, providing a suitable raw material base for subsequent processes such as carding. With the continuous development of cotton opening, various cotton opening devices have emerged, such as a step-by-step cotton opening device.
[0003] Currently, cotton opening devices on the market mainly focus on improving the opening speed. Existing cotton opening devices generally consist of a box, a feeding roller, multi-stage opening rollers, and a stripping roller. By setting up multi-stage opening rollers, the cotton is opened step by step, making the cotton clumps smaller and looser. However, existing opening devices use rigid opening rollers (such as toothed rollers), which easily lead to fiber breakage, an increase in the short fiber rate, and affect the yarn quality. Therefore, a step-by-step cotton opening device that can gradually use coarse opening and needle rollers covered with elastic materials is proposed to reduce fiber cutting and achieve low-damage opening. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a step-by-step opening device for cotton, which has the advantages of gradually using coarse opening and needle rollers covered with elastic materials, reducing fiber cutting and low-damage opening. It solves the problem that existing opening devices use rigid opening rollers (such as toothed rollers), which easily lead to fiber breakage, increased short fiber rate, and affect yarn quality.
[0005] To achieve the above-mentioned goal of gradually using needle rollers with coarse opening and covering elastic material, reducing fiber cutting, and low-damage opening, this utility model provides the following technical solution: a cotton step-by-step opening device, including an opening machine body, a feeding conveyor belt fixedly installed on the left side of the opening machine body, a discharging conveyor belt fixedly installed on the right side of the opening machine body, and an opening mechanism provided inside the opening machine body.
[0006] The loosening mechanism includes a primary loosening roller, short and thick conical nails, a working groove, a secondary loosening roller, comb needles, a variable frequency fan, a negative pressure pipe, and a filter screen. The primary loosening roller is installed inside the loosening machine body, and several short and thick conical nails are welded to the outside of the primary loosening roller. The working groove is opened inside the loosening machine body. The secondary loosening roller is installed inside the loosening mechanism, and several comb needles are welded to the outside of the secondary loosening roller. The variable frequency fan is fixedly installed inside the loosening machine body. The negative pressure pipe is fixedly installed inside the loosening machine body, and a filter screen is installed at the bottom of the negative pressure pipe.
[0007] Furthermore, a fixed box is fixedly installed on the top of the discharge conveyor belt, and a discharge port is opened on the right side of the fixed box. By setting the fixed box, it is possible to prevent cotton from falling from the side during the conveying process.
[0008] Furthermore, a discharge plate is fixedly installed inside the body of the loosening machine, and the discharge plate is located on the left side of the discharge conveyor belt.
[0009] Furthermore, the outer surface of the secondary opening roller is provided with a wear-resistant coating, which can prevent the corrosion of the cotton inside the secondary opening roller by moisture.
[0010] Furthermore, the comb needles are provided with a polyurethane layer on the outside. By providing the polyurethane layer, the cotton clumps can be flexibly opened, reducing fiber damage.
[0011] Furthermore, a PLC controller is installed at the front of the opening machine body, and the PLC controller is electrically connected to the first-stage opening roller, the second-stage opening roller and the variable frequency fan through wires.
[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0013] This cotton uses a step-by-step opening device. By setting up an opening mechanism, when the cotton is opened step by step, the PLC controller is turned on, and the cotton ball is put into the feeding conveyor belt. After the cotton enters the opening machine body, it is coarsely opened by the coarse and short conical nails arranged on the outside of the first-stage opening roller. Then, the cotton ball is finely opened by the polyurethane layer on the outside of the second-stage opening roller and the polyurethane layer on the outside of the comb needles. Then, the variable frequency fan and negative pressure pipeline are started, so that the opened cotton falls onto the discharge conveyor belt and is discharged. This opening mechanism can gradually use coarse opening and needle rollers covered with elastic material to reduce fiber cutting and low-damage opening. Attached Figure Description

[0025] In the case implementation, the first-stage opening roller 401 uses short, coarse conical nails 402 with a tooth height of eight millimeters, a tooth pitch of ten millimeters, and a spacing of three centimeters. There are several short, coarse conical nails 402 with a relatively large spacing, which are used for coarse opening and are less likely to damage cotton fibers. The second-stage opening roller 404 uses polyurethane-coated comb needles 405 with a tooth density of five teeth per square centimeter, which are used for fine opening and are conducive to flexible opening.
[0026] In the implementation of the case, a PLC controller 9 is set in front of the opening machine body 1.

[0027] When implementing this procedure, please follow these steps:
[0028] 1) First, when the cotton is being opened in stages, turn on the PLC controller and put the cotton ball into the feeding conveyor belt 2;
[0029] 2) Then, after the cotton enters the body 1 of the opening machine, it is coarsely opened by the short and thick conical nails 402 arranged on the outside of the primary opening roller 401;
[0030] 3) The cotton clump is then finely opened by the polyurethane layer 8 on the outside of the secondary opening roller 404 and the polyurethane layer 8 on the outside of the comb needle 405.
[0031] 4) Finally, the variable frequency fan 406 and negative pressure pipeline 407 are started, so that the opened cotton falls onto the discharge conveyor belt 3 and is discharged.
[0032] In summary, this cotton-opening device, through the setting of the opening mechanism 4, activates the PLC controller during the step-by-step opening of the cotton, and puts the cotton ball into the feeding conveyor belt 2. After the cotton enters the body of the opening machine 1, it is coarsely opened by the coarse and short conical nails 402 arranged on the outside of the first-stage opening roller 401. Then, the cotton ball is finely opened by the polyurethane layer 8 on the outside of the second-stage opening roller 404 and the polyurethane layer 8 on the outside of the comb needles 405. Finally, the variable frequency fan 406 and the negative pressure pipe 407 are started, so that the opened cotton falls onto the discharge conveyor belt 3 for discharge. This opening mechanism 4 can gradually use coarse opening and needle rollers covered with elastic material to reduce fiber cutting and achieve low-damage opening.
