AI Technical Summary
The dust removal knife of the existing card machine collides with hard impurities when rotating at high speed, resulting in wear of the blade and affecting the removal effect. When the blade loses its sharpness, it needs to be replaced as a whole, which is cumbersome to disassemble and assemble, which increases production costs.
A replacement dust collector knife for carding is designed, adopting a separate design, which divides the dust collector into two parts: the base body and the knife body. The knife body is connected to the base body through the plug-in method of sliding grooves and sliders, making it easy to replace.
By replacing only the worn knife body without the need to replace the dust removal knife as a whole, the production cost is significantly reduced, the disassembly and assembly is convenient, and the production efficiency is improved.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cotton carding machine equipment, in particular to a replaceable dust removal knife of a cotton carding machine. Background Art
[0002] In the textile industry, the dust removal knife on the carding machine is used to remove impurities and short fibers on the raw materials to ensure product quality. However, impurities on the raw materials, especially those with greater hardness, will frequently collide with the dust removal knife when in direct contact with the high-speed rotation. This collision will continuously wear the blade of the dust removal knife, causing it to gradually lose its sharpness and affect the removal effect.
[0003] At present, when the dust removal knife can no longer be used, the dust removal knife needs to be replaced as a whole, which is not only cumbersome to disassemble and assemble, increasing the workload, but also greatly increasing the production cost. Utility Model Content
[0004] In view of the above-mentioned problem that the dust removal knife currently needs to be replaced as a whole, which not only makes disassembly and assembly cumbersome and increases workload, but also greatly increases production costs, the utility model provides a replaceable dust removal knife for a cotton carding machine.
[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0006] A replaceable dust removal knife for a cotton carding machine comprises a base and a knife body, a slide groove is provided on one side of the base, a slider is connected to one side of the knife body, the knife body is adapted and snap-fitted into the slide groove through the slider, and the blade of the knife body is located on the outside of the base.
[0007] Furthermore, the base includes a first connecting section and a second connecting section, the first connecting section has an arc-shaped cross section, the second connecting section has a triangular cross section, and the slide groove is located on the second connecting section.
[0008] Furthermore, the slide groove is approximately in a cross shape, and the slide groove is arranged on the top of the second connecting section.
[0009] Further, one side of the second connection extends downward to form an extension plate.
[0010] Furthermore, the cross-section of the extension plate is arc-shaped.
[0011] Furthermore, a baffle is fixed on one side of the bottom of the extension plate.
[0012] Furthermore, the slider is plate-shaped, and the knife body is detachably fixedly connected to the slider via a plurality of connecting columns.
[0013] Furthermore, a groove matched with the blade body is arranged at the top of the second connecting section, and the sliding groove is arranged at the bottom of the groove.
[0014] Furthermore, air duct connectors are provided at the ends of both ends of the first connecting section.
[0015] The utility model has the following beneficial effects: the utility model separates the dust removal knife on the carding machine into a base and a knife body. When the dust removal knife is worn out while removing impurities from raw materials, only the knife body can be replaced without replacing the dust removal knife as a whole, which greatly reduces production costs. The knife body is connected to the base by plugging, which is convenient for disassembly and assembly, easy for replacement, and is conducive to improving production efficiency.

[0023] The utility model discloses a replaceable dust removal knife of a cotton carding machine. An implementation mode of the utility model is specifically described below in conjunction with the accompanying drawings.
[0024] like Figure 1 As shown, a replaceable dust removal knife of a carding machine comprises a base body 1 and a knife body 2, wherein the base body 1 comprises a first connecting section and a second connecting section. Figure 2 and Figure 3 As shown, the cross section of the first connecting section is arc-shaped, the cross section of the second connecting section is triangular, and the first connecting section is located on the left side of the second connecting section. The outer edge of the top of the second connecting section is concave inward to form a groove, and the bottom of the groove has a sliding groove 5 that is approximately cross-shaped. Figure 4 and Figure 5As shown, the outer side of the second connecting section extends downward to form an extension plate 3, and the cross section of the extension plate 3 is arc-shaped. An arc-shaped baffle plate 6 is fixed to the left side of the extension plate 3.
[0025] Combination Figure 6 and Figure 7 As shown, one side of the blade body 2 has a blade, and the blade is made of a highly wear-resistant alloy material, which can effectively enhance the wear resistance of the blade and significantly reduce the wear caused when removing impurities from the raw material. The bottom of the blade body 2 is connected to a slider 7 through a plurality of connecting columns 8, and the slider 7 is in the shape of a plate. The blade body 2 is inserted into the slide groove 5 from the end opening of the slide groove 5 and is engaged with the second connecting section, and the blade of the blade body 2 is located on the outside of the second connecting section. The ends of the second connecting section are provided with air duct connectors 4, which are used to connect to the air duct to absorb impurities and short fluff removed by the blade body 2.
[0026] The utility model adopts a separate design for the dust removal knife on the carding machine, and divides the dust removal knife into two parts, a base body 1 and a knife body 2. When the dust removal knife is worn out by removing impurities from raw materials, only the knife body 2 can be replaced, and the dust removal knife does not need to be replaced as a whole, which greatly reduces the production cost. The knife body 2 is connected to the base body 1 by plugging, which is convenient for disassembly and assembly, easy to replace, and conducive to improving the production effect.
[0027] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
