Description

Technical Field

[0001] The present invention relates to the technical field of brush manufacturing equipment, and particularly relates to a brush wire taking mechanism for precise wire taking on a brush manufacturing equipment. Background Art

[0002] The brush wire taking mechanism is a part of the brush manufacturing equipment, and provides a set number of brush wires for the brush manufacturing equipment to ensure precise hair implantation. The traditional brush wire taking mechanism rotates the main shaft continuously, and drives the hair taking knife swing arm to swing up and down continuously through an eccentric wheel. The hair taking knife installed on the hair taking knife swing arm continuously takes out the brush wires. However, this way of taking brush wires is not conducive to the brush wires entering the brush wire taking port and being filled, resulting in uneven amount of brush wires taken each time, and the number of brush wires taken is not precisely controlled. Especially in the case of only requiring to take one brush wire each time, there will be a phenomenon of missing taking. Therefore, in order to avoid the disadvantages existing in the prior art, it is necessary to improve the prior art. Summary of the Invention

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] As Figure 1 shown, the existing brush wire taking mechanism rotates the main shaft 2 continuously. The eccentric wheel 27 drives the wool-taking knife swing arm 5 to swing up and down continuously. The wool-taking knife 6 installed on the wool-taking knife swing arm 5 takes out the brush wire continuously. However, this way of taking the brush wire is not conducive to the brush wire entering the brush wire taking port and being filled, resulting in uneven amount of brush wire taken each time, and the quantity control of the taken brush wire is inaccurate. Especially in the case where only one brush wire is required to be taken each time, there will be a phenomenon of missing taking.

[0022] As Figures 2 to 3A brush wire taking mechanism for precise wire taking on a brush making device according to the present invention is shown, which includes a hair box 1, a main shaft 2, a hair taking swing arm mounting shaft 3 and a hair taking knife swing shaft 4. The hair taking swing arm mounting shaft 3 is arranged above the left of the main shaft 2, and the hair taking knife swing shaft 4 is arranged below the right of the main shaft 2. A hair taking knife swing arm 5 extending to the right is rotatably connected to the hair taking knife swing shaft 4. A hair taking knife 6 is installed on the right side of the hair taking knife swing arm 5. The hair box 1 is arranged on the right side of the hair taking knife 6. A hair taking swing arm 7 rotatably connected to the hair taking swing arm mounting shaft 3 is installed on the hair taking swing arm mounting shaft 3. A conjugate cam is installed on the main shaft 2. The conjugate cam is provided with a first cam 8 and a second cam 9. The hair taking swing arm 7 is provided with a first swing arm 10 extending downward. A first idler wheel 11 is installed on the first swing arm 10. The outer side of the first idler wheel 11 is in rolling connection with the outer side of the first cam 8. The hair taking swing arm 7 is provided with a second swing arm 12 extending to the right. A second idler wheel 13 is installed on the second swing arm 12. The outer side of the second idler wheel 13 is in rolling connection with the outer side of the second cam 9. An upper joint bearing 14 is installed on the right side of the second swing arm 12. A lower joint bearing 15 is installed on the middle side of the hair taking knife swing arm 5. The upper joint bearing 14 and the lower joint bearing 15 are connected by a connecting rod 16. The lower part of the first cam 8 is provided with a first convex arc surface 17 with the farthest distance from the center of the main shaft 2. The lower left part of the second cam 9 is provided with a second convex arc surface 18 with the farthest distance from the center of the main shaft 2. A brush wire taking port 19 is provided on the right side of the lower part of the hair taking knife 6. By setting the hair taking swing arm 5 and the conjugate cam to control the up and down swing of the hair taking knife 6, the conjugate cam is provided with the first cam 8 and the second cam 9. The lower part of the first cam 8 is provided with the first convex arc surface 17 with the farthest distance from the center of the main shaft 2. The lower left part of the second cam 9 is provided with the second convex arc surface 18 with the farthest distance from the center of the main shaft 2. The first cam 8 controls the up and down swing of the hair taking knife 6. When the hair taking knife 6 moves up or down near the highest position, the second cam 9 controls the up and down peristalsis of the hair taking knife 6, so that when the brush wire taking port 19 contacts the brush wire, up and down peristalsis is realized, which is beneficial to the brush wire entering the brush wire taking port 19 and being filled, and makes the amount of each brush wire taken more uniform. Especially in the case of only requiring to take one brush wire each time, it is more beneficial to avoid missing taking.

[0023] A brush wire taking port depth adjusting member 20 is installed on the brush wire taking port 19. The brush wire taking port depth adjusting member 20 is used to adjust the number of brush wires taken.

[0024] The size of the first cam 8 is larger than that of the second cam 9, which is more conducive to controlling the amplitude of the up and down peristalsis of the hair taking knife 6 by the first cam 8.

[0025] The upper left part of the first cam 8 is provided with a first plane 21, and the lower right part of the second cam 9 is provided with a second plane 22, which is conducive to controlling the acceleration when the hair taking knife 6 moves upward, so that the hair taking knife 6 can be quickly lifted, saving time and improving efficiency.

[0026] Both the first swing arm 10 and the second swing arm 12 are provided with weight-avoiding holes 23 to reduce the weight of the hair-taking swing arm 7 and save the energy consumption for driving the hair-taking swing arm 7.

[0027] The first swing arm 10 is provided with a first elongated hole 24 for installing the first idler wheel 11. The first elongated hole 24 is arranged longitudinally, and the movement height of the hair-taking knife 6 is adjusted by adjusting the installation height of the first idler wheel 11.

[0028] The hair-taking knife swing arm 5 is provided with a second elongated hole 25 for installing the lower joint bearing 15. The second elongated hole 25 is arranged longitudinally and transversely, and the vertical swing amplitude of the hair-taking knife 6 is adjusted by adjusting the installation position of the lower joint bearing 15 and the hair-taking knife swing arm 5.

[0029] A longitudinal internal thread hole 26 is provided at the top of the first elongated hole 24. The internal thread hole 26 is screwed with a fastening screw, and the fastening screw abuts against the second idler wheel 13 to prevent the second idler wheel 13 from shifting upward under the impact of the second cam 9.

[0030] An opening is provided on the left side of the bottom of the hair box 1, which is beneficial for the brush wire to smoothly enter the brush wire taking port 19 of the hair-taking knife 6.

[0031] The above are only the preferred embodiments of the present invention, and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
