Description

Spiral cutting device

Technical Field

The utility model relates to a hair cutting device especially relates to a hair cutting device of reciprocating type razor.

Background

Currently, hair cutting devices on the market are of various types, generally rotary or reciprocating. The reciprocating moving knife is contacted with the static knife when in action, and the static knife is easy to damage due to large reciprocating inertia and large vibration. The hair cutting devices of reciprocating shavers achieve hair cutting by rotating a moving blade relative to a stationary blade. Generally, the number of the movable blades is fixed, once one movable blade or part of the blades are worn, the whole movable blade needs to be replaced, and the cost is high. The assembly and shaving effect require a very high precision for the assembly and the fitting. The existing movable knife is generally integrated, even though the movable knife is a simple split body of an inner knife and an outer knife, and the structure of the actual cutting part of the movable knife can not be adjusted at the later stage. In addition, the existing rotary moving blade structure has many problems, such as the hair is easy to slip off from the cutting edge part, the hair is pulled or clamped, the hair accumulated on the cutting edge part is too much, so that the load borne by a power source in the cutting process is too large, the skin feeling in the hair cutting process is not ideal, even the skin is scratched, and in order to solve some problems, some manufacturers bring other problems or aggravate defects in other aspects, some manufacturers cannot perfectly solve the problems.

The utility model discloses a hair cutting device adopts the roller bearing unit combination formula to move the sword, moves the sword and carries out S type cutting route at sword net internal surface, and the cutting is more sharp effective, and it has broken the cutting mode of traditional tool bit completely, has effectively avoided the tradition to shave various problems that appear, especially the problem is piled up to the hair. The movable knife of the structure is of a unit combination type, can be adjusted at the later stage, and can replace part of the movable knife abrasion units. Greatly reduces the maintenance cost, has small abrasion to the static knife, has no reversing and avoids various problems caused by reversing.

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings.

Drawings

Fig. 1 is a schematic structural diagram of an embodiment of the spiral cutting apparatus of the present invention.

Fig. 2 is an exploded view of the assembly of fig. 1.

Detailed Description

Fig. 1 and 2 show an embodiment of the spiral cutting device of the present invention, which comprises a housing, a blade net 1 with hair guiding holes 11 on the net surface, a moving blade assembly installed in the housing and cooperating with the inner surface of the blade net to shave, a first pull-down member 5, and a second pull-down member 6, wherein the blade net has an arch-shaped cross section. The movable cutter component comprises a rolling roller 2 transversely arranged in a shell, a plurality of circular blade cutter units 3 with cutting edges at the edges, and a transmission part 4 which is positioned at the end part of the roller and drives the roller 2 to roll, wherein the circular blade cutter units 3 are uniformly spaced and inclined and are limited on the roller in a sleeving manner, and the circular blade cutter units 3 of the embodiment are composed of cutting circular blades and spacing pieces for spacing. The transmission piece 4 drives the roller 2 to roll forwards or backwards, so that the blade of the circular knife unit on the roller 2 realizes S-shaped cutting action on the inner surface of the knife net. Two ends of the rolling shaft 2 are respectively transversely arranged in the shell through bearings 7 in a rolling manner, so that noise is effectively reduced, and the rolling shaft rolls at a high speed. After hair entered through the hair guiding hole 11 of the cutter mesh 1, the cutting edge of the cutting circular blade of the circular blade unit 3 is matched with the lower inner surface of the cutter mesh to cut hair, and the cut hair falls into the interval between every two circular blades, and the hair after cutting is brought out due to the rolling motion of the movable cutter assembly, so that the hair after cutting falls and is collected in one position, thereby effectively avoiding hair accumulation and other problems caused by hair accumulation, and the structure is more favorable for cleaning and waterproofness.

The upper end of the first pull-down piece 5 is connected with the opposite side surface of the rolling direction of the cutter mesh rolling shaft, and the lower end of the first pull-down piece 5 is connected with the inner bottom surface of the shell or the supporting piece below the inner part of the shell. The first pull-down piece 5 can enable the cutter net to be stably matched with the movable cutter assembly, particularly a circular blade cutter unit, the cutter net is prevented from shifting, and the noise reduction effect is obvious. In order to further stabilize the knife net, the embodiment further comprises a second pull-down part 6, the upper end of the second pull-down part 6 is connected to the side face in the rolling direction of the knife net roller, and the lower end of the second pull-down part 6 is connected to the inner bottom surface of the shell or the supporting part below the inner bottom surface of the shell.

The transmission part of this embodiment is gear drive assembly, gear drive assembly by the action wheel of power driving piece drive, with the action wheel engaged with from the driving wheel constitution. The gear transmission can be designed and assembled conveniently, and the meshing mode is stable. Of course, the driving can be carried out by other transmission modes.

Although the present invention has been described with reference to the specific embodiments, it should be understood that various changes and modifications can be made by those skilled in the art without departing from the spirit and scope of the invention.
