Description

Technical Field

[0001] The utility model relates to the technical field of wool shearing machines, in particular to a high-efficiency circular knife tool for wool shearing machines. Background Art

[0002] The circular knife of the shearing machine is a key component of the shearing machine. Its function is to help trim the hair and keep it neat and orderly. The circular knife of the shearing machine is generally made of steel with high hardness, wear resistance and non-deformation. Some high-end circular knives are made of ceramic materials, which can better maintain the circular knife of the shearing machine and extend its service life.

[0003] During the use of the circular knife of the shearing machine, due to the small angle between the bottom end of the blade and the surface of the roller, the hair adheres to the angle during the shearing process, and it is difficult to suck it out through the external dust cover. When the hair adheres to a certain extent, it is necessary to stop the machine for cleaning, otherwise it will affect the cutting quality of the hair. Long-term shutdown for cleaning affects the working efficiency of the shearing machine. Therefore, we proposed an efficient circular knife tool for shearing machines to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that the angle between the bottom end of the blade and the surface of the roller is small, which causes hair to adhere to the angle during the shearing process, and proposes a high-efficiency circular knife tool for shearing machines.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A high-efficiency circular knife tool for a hair clipper comprises a roller and a plurality of blades mounted on the surface of the roller, a padding strip is arranged between two adjacent blades, the padding strip is fixed on the surface of the roller, and both sides of the padding strip are in contact with the blades, and an arc-shaped concave surface is arranged on the upper surface of the padding strip, thereby increasing the angle between the blades and the surface of the roller, thereby facilitating the outflow of hair.

[0007] As a preferred technical solution of the utility model, the blade is spiral-shaped, and the number of blades is 46 to 48. Compared with the existing circular knife, the number of blades is increased, thereby improving the shearing efficiency.

[0008] As a preferred technical solution of the utility model, the pad strip is detachably mounted on the roller shaft by means of screws, and the pad strip can be replaced.

[0009] As a preferred technical solution of the utility model, the pad is provided with a countersunk hole for installing a screw, and the end of the countersunk hole is provided with a cover flush with the arc-shaped concave surface, so that the screw does not protrude from the pad, thereby not hindering the adsorption of hair.

[0010] As a preferred technical solution of the utility model, the surface roughness value of the arc-shaped concave surface is Ra0.2-Ra1.6, and the surface roughness of the arc-shaped concave surface is controlled, thereby facilitating the sliding of hair.

[0011] The beneficial effects of the utility model are:

[0012] 1. By installing a pad with an arc-shaped concave surface between the blades, the angle between the bottom end of the blade and the roller surface is increased, thereby reducing the factor of hair adhering to the angle, making it easier to suck out the hair through the external dust cover.

[0013] 2. The bottom end of the blade can be reinforced by setting the pad, thereby reducing the vibration of the blade during the shearing process and improving the shearing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Reference Figure 1-2 , a high-efficiency circular knife tool for shearing machine, comprising a roller shaft 1 and a plurality of blades 2 mounted on the surface of the roller shaft 1, wherein the blades 2 are spiral-shaped, and the number of the blades 2 is 46 to 48. Compared with the existing circular knife with 24 to 28 blades 2, the number of the blades 2 is increased, thereby improving the shearing efficiency;

[0019] Among them, a pad strip 3 is arranged between two adjacent blades 2, and the pad strip 3 is also spiral-shaped. The pad strip 3 is detachably mounted on the roller shaft 1 by means of a screw 4, and the pad strip 3 can be replaced. Both sides of the pad strip 3 fit with the blade 2, so that hair cannot enter the bottom end of the blade 2, and an arc-shaped concave surface 5 is arranged on the upper surface of the pad strip 3 to increase the angle between the blade 2 and the surface of the roller shaft 1. The surface roughness value of the arc-shaped concave surface 5 is Ra0.2-Ra1.6, and the surface roughness of the arc-shaped concave surface 5 is controlled, so as to facilitate the outflow of hair;

[0020] Secondly, a countersunk hole for installing the screw 4 is provided on the pad strip 3, and a cover 6 flush with the arc-shaped concave surface 5 is provided at the end of the countersunk hole, so that the screw 4 does not protrude from the pad strip 3, thereby not hindering the adsorption of hair.

[0021] In this embodiment: when installing the blade 2 and the pad 3, the blade 2 and the pad 3 are rotated onto the roller shaft 1 from the end of the roller shaft 1 in sequence, and fixed by screws 4;

[0022] By installing a pad strip 3 with an arc-shaped concave surface 5 on its upper surface between the blades 2, the angle between the bottom end of the blade 2 and the surface of the roller 1 is increased, thereby reducing the factor of hair adhering to the angle, making it easier to suck out the hair through the external dust cover.

[0023] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
