[0011] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.
[0012] Embodiment 1:
[0013] like Figure 1 , Figure 2 As shown, the utility model discloses a wire cutter for a hair implanting machine, comprising a knife seat 1, a fixed knife body 5 and a movable knife body 4, an L-shaped hollow channel is arranged inside the knife seat 1, and the L-shaped hollow channel comprises a horizontal channel 2 and a vertical channel 3, the movable knife body 4 is arranged in the horizontal channel 2, and a fixed knife body 5 is arranged on the knife seat 1 on the side of the vertical channel 3, the end of the movable knife body 4 contacts the end of the fixed knife body 5 in the vertical channel 3, a wire feeding hole 8 is arranged on the movable knife body 4 in the vertical channel 3, a wire guide hole 9 is arranged inside the knife seat 1 at a position corresponding to the wire feeding hole 8, the wire guide hole 9 passes through the knife seat 1, and the steel wire passes through the wire guide hole 9 and the wire feeding hole 8 to enter the vertical channel 3, the fixed knife body 5 is arranged at an angle, the upper end surface of the end of the fixed knife body 5 located in the vertical channel 3 is the highest point, and the highest point of the fixed knife body 5 contacts the lower surface of the movable knife body 4 in the vertical channel 3.
[0014] An L-shaped hollow channel, namely a horizontal channel 2 and a vertical channel 3, is arranged in the knife seat 1, wherein the horizontal channel 2 accommodates the movable knife body 4, and the movable knife body 4 reciprocates in the horizontal channel 2 under the action of the power mechanism. The horizontal channel 2 can effectively limit the movement trajectory of the movable knife body 4. During use, the movable knife body 4 is always accurately limited in the horizontal channel 2, and the reciprocating precision and stability are high. The vertical channel 3 is the area for wire cutting. The end of the fixed knife body 5 extends into the vertical channel 3, and the end of the movable knife body 4 also extends into the vertical channel 3. The fixed knife body 5 is arranged obliquely, and the end of the fixed knife body 5 that contacts the movable knife body 4 is the higher end, and the other end is the lower end. The higher end of the fixed knife body 5 contacts the lower surface of the movable knife body 4, which is a line contact. When the movable knife body 4 reciprocates, a triangular gap will be formed between the movable knife body 4 and the fixed knife body 5, so even if there are some impurities such as iron filings between the two, they can fall off during the movement, and it is not easy to cause wear to the movable knife body 4. Under normal working conditions, the steel wire passes through the wire guide hole 9 into the knife seat 1, then into the wire feed hole 8, passes out from the bottom of the movable knife body 4, and enters the vertical channel 3. At this time, the wire feed hole 8 is located on the side of the fixed knife body 5. After the steel wire passes through a certain length, the movable knife body 4 moves so that the wire feed hole 8 moves to the top of the movable knife body 4. During this process, the end of the movable knife body 4 squeezes and cuts the steel wire in the wire feed hole 8 to cut it off, and then the movable knife body 4 withdraws. The above process is repeated to achieve cutting of the steel wire.
[0015] In the above process, the contact area between the movable blade body 4 and the fixed blade body 5 is small, so there is less wear and tear and a long service life.
[0016] An upper limit plate 6 is arranged in the horizontal channel 2 on the upper side of the movable knife body 4, and a lower limit plate 7 is arranged in the horizontal channel 2 on the lower side of the movable knife body 4. Two tightening bolts 11 are arranged in the knife seat 1 on the upper side of the upper limit plate 6, and two tightening bolts 11 are arranged in the knife seat 1 on the lower side of the lower limit plate 7. One end of the upper limit plate 6 extends into the vertical channel 3 and abuts against the end of the vertical channel 3. A through hole 10 is arranged on the upper limit plate 6 at a position corresponding to the wire guide hole 9 for the steel wire to pass through. A limiting column 13 is arranged on the lower surface of the lower limit plate 7, and a limiting hole 14 is arranged on the knife seat 1 at a position corresponding to the limiting column 13, and the limiting column 13 is inserted into the limiting hole 14.
[0017] The width of the horizontal channel 2 is consistent with or close to the width of the movable knife body 4, so as to ensure that the width direction of the movable knife body 4 can be limited, and the height direction of the horizontal channel 2 can be greater than the height of the movable knife body 4, and an upper limit plate 6 is set on its upper side, and a lower limit plate 7 is set on its lower side, and the positioning is adjusted by the tightening screw to achieve adjustable height position of the movable knife body 4. After long-term use, when the fixed knife body 5 and the movable knife body 4 are worn, the position of the movable knife body 4 can be adjusted to make the movable knife body 4 contact with the fixed knife body 5 to ensure a stable cutting effect. In order to prevent the upper limit plate 6 and the lower limit plate 7 from being displaced during the reciprocating motion of the movable knife body 4, the upper limit plate 6 is used to abut against the side wall of the vertical channel 3, and in order to allow the steel wire to move smoothly into the vertical channel 3, there is a gap between the lower limit plate 7 and the farthest side wall of the vertical channel 3. Therefore, the lower limit plate 7 adopts the design of a limit column 13, and the cooperation of the limit column 13 and the limit hole 14 is used to limit the displacement of the lower limit plate 7 in the length direction, which has higher stability.
[0018] The wire feeding hole 8 is a truncated cone structure with a larger upper portion and a smaller lower portion, and the upper end diameter of the wire feeding hole 8 is larger than the diameter of the wire guide hole 9. In normal operation, the wire feeding hole 8 reciprocates with the movable blade body 4, and the upper limit plate 6 fits with the movable blade body 4. In order to avoid interference between the steel wire inside the wire feeding hole 8 of the movable blade body 4 and the steel wire inside the wire guide hole 9 and the through hole 10, the wire feeding hole 8 with a larger upper portion and a smaller lower portion is adopted. During the reciprocating motion of the movable blade body 4, the through hole 10 and the wire guide hole 9 are always within the range of the wire feeding hole 8, and no damage is caused to the steel wire.
[0019] The upper part of the lower limit plate 7 near one end of the vertical channel 3 is in a chamfered structure 12, and the end of the lower limit plate 7 is aligned with the side wall of the vertical channel 3 or a part of the lower limit plate 7 is exposed in the vertical channel 3. In order to prevent the cut steel wire from interfering with the lower limit plate 7 and the bottom wall of the horizontal channel 2 when it is output from the wire feeding hole 8 into the vertical channel 3 and affecting the normal downward movement of the steel wire, the end of the lower limit plate 7 is in a chamfered structure 12, which can ensure that the end of the steel wire will not abut against the lower limit plate 7, and the downward movement of the steel wire is smoother and more stable.
