Description

Technical Field

[0001] The utility model relates to the technical field of hair cutting brush equipment, in particular to a hair cutting brush mechanism. Background Art

[0002] The processing of brushes is mainly divided into two steps. First, the bristles are implanted into the brush handle, and then the brush is trimmed.

[0003] The existing publication number CN112021772A discloses a brush clamp device and a processing method for cutting and grinding bristles of different heights, which adopts a left-parting comb and a right-parting comb to comb and press the bristles, and adopts a longitudinal moving device of the hair comb to drive the left and right hair combs to be inserted into the bristles, and utilizes a transverse moving device of the hair comb to drive the left and right hair combs to comb and separate the bristles to both sides respectively, and at the same time utilizes a vertical lifting device to press the bristles downward, and the left and right hair combs are used to comb the bristles to cooperate with the cutting operation of the bristles, which cleverly solves the problem of cutting bristles of different heights, and at the same time cooperates with the grinding device to realize effective grinding of the cut surface of the bristles, forming a semicircle after grinding, and the bristles on the same brush can be cut at different heights according to needs, and at the same time, efficient grinding of the cut surfaces of the bristles of different heights can be achieved, with good cutting and grinding effects, convenient batch processing and high production efficiency.

[0004] The prior art uses a vertical downward pressure method to cut the brush, which is relatively poor compared to the staggered shearing method with two blades. Therefore, we propose a brush cutting mechanism. Utility Model Content

[0005] The purpose of the utility model is to provide a brush cutting mechanism to solve the problem in the prior art that when cutting the brush, the brush is sheared by vertical downward pressure, which is relatively inferior to the staggered shearing of two blades.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a hair cutting brush mechanism, comprising a first shell and a second shell, wherein the first shell and the second shell are respectively installed with a first end cover and a second end cover at both ends after assembly; the first shell is located on one side of the second shell and a first blade is installed, and a second blade is provided on one side of the first blade; the first shell and the second shell are located on one end of the first end cover and a transmission shaft is installed, the transmission shaft passes through the first end cover, and an eccentric shaft is provided at the end of the transmission shaft away from the first end cover, the eccentric shaft is installed with a hinge shaft, the hinge shaft drives a blade holder, and the blade holder is connected to the second blade.

[0007] Preferably, a plurality of magnets are installed on a side of the first blade away from the second blade, and a plurality of magnets are installed on a side of the second blade away from the first blade.

[0008] Preferably, the first shell includes a plurality of protrusions, and the first blade and the second blade are both provided with through holes that cooperate with the protrusions.

[0009] Preferably, the first shell is provided with a limiting groove, and the hinge shaft comprises a cylinder, which cooperates with the limiting groove.

[0010] Preferably, the hinge shaft comprises a sphere, and the sphere cooperates with the blade holder.

[0011] Preferably, the transmission shaft is provided with a second bearing at the first end cover, and the transmission shaft is provided with a first bearing at the first housing and the second housing.

[0012] Preferably, an elastic pad is provided between the first blade and the second blade.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The transmission shaft drives the eccentric shaft to rotate, and drives the hinge shaft hinged thereon to perform eccentric motion. Since the cylinder on the hinge shaft is restricted by the limit groove of the shell, the two ends of the hinge shaft can only perform reciprocating motion. The sphere on the hinge shaft drives the blade holder, and the blade holder drives the first blade to perform reciprocating motion. The teeth on the first blade and the teeth on the second blade are misaligned, forming a cutting action, thereby cutting off the hair. Compared with vertical downward pressure cutting, the cutting effect of the present application is better.

[0015] 2. Magnets are set on one side of the first blade and the second blade. The magnets make the second blade more closely attracted, thereby improving cutting efficiency. The setting of the elastic pad also increases the fit of the two blades. BRIEF DESCRIPTION OF THE DRAWINGS
