Detailed Description
The core of the invention is to provide a high-speed and high-yield doffer metal card clothing.
The invention will be further explained with reference to the accompanying drawings:
the high-speed high-yield doffer metal card clothing comprises a base 1 and three main comb teeth 2 protruding from the base 1, wherein the main comb teeth 2 comprise front teeth of a working surface and back teeth of a transfer surface; the front teeth are of sickle structures and comprise tooth tips 3, tooth edges and small corners 4, the end surfaces of the tooth tips are parallel to the base 1, the horizontal direction of the small corners 4 and the base 1 form a horizontal working surface horizontally, and the vertical direction of the small corners is an arc line and is connected with the tooth edges; the back teeth are provided with four convex triangular prism teeth 5, the outline of the back teeth is divided into a first back tooth line and a second back tooth line, the triangular prism teeth 5 are triangular prism teeth with isosceles right triangle bottom surfaces, and the bottom surfaces are in the same direction with the outline of the back teeth; the back tooth contour line is an arc line, a first back tooth line is connected with the horizontal working surface of the front tooth tip 3, and a second back tooth line is smoothly connected with the front tooth of the adjacent main comb tooth 2 by the arc line; the small corner 4 divides the front tooth contour line into a first front tooth line and a second front tooth line; the first front tooth line is connected with the tooth tip 3 and the small corner 4, and the second front tooth line is connected with the second back tooth line in a smooth arc manner after being straight with the base part 1; back teeth and front teeth of two adjacent main comb teeth 2 form funnel-shaped tooth gaps 6 with large openings and small tooth bottoms; the height difference range of the triangular ridge 5 is 0.10-0.20 mm, the tooth height range of the front tooth is 0.50-1.00 mm, and the tooth parallel base 1 width of the front tooth is 0.30-0.55 mm.
During the specific use, working face before the work avris protrusion of former broach is equipped with, and the back of the tooth adds four triangle arriss, form a tooth root "hook" tooth structure promptly, in holding the fibre transfer process, the back of the tooth triangle arris holds and annotates the fibre, hold in the palm in the regional support of "hook" of main broach 2 front working face with the fibre and take away, the transfer effect of holding of broach has been improved, simultaneously "funnel" that tooth working face and the back of the tooth formed also helps control and release fibre, through increasing hook form pinpoint depth of operation, the tooth depth that makes metal card clothing has increased more than 30%, increased the transfer fibre volume. In addition, the triangular edges of the metal card clothing with the sickle tooth structure are increased, the friction resistance is increased, the fiber falling net in high speed and high yield is eliminated, and the strip outlet can be improved to 180-200m/min from 80-90 m/min.
Example 1:
three main comb teeth 2 are protruded along the strip-shaped base 1, a concave platform which is 0.3-0.6mm wider than the base 1 is arranged at the position of 0.5-1mm of each main comb tooth 2 along the working edge to the tooth depth direction, and the concave platform and the back edge form a sickle-shaped needle point; and four triangular edges with the height of 0.1-0.2mm are arranged at the position 0.8-2mm below the back edge. The back triangular edge protrudes 45 degrees along the horizontal direction. In the structure shown in fig. 2, the triangular edges of the back side are arranged between the first oblique line and the second oblique line of the tooth back and can be connected in a straight line or in an arc. The front edge of the tooth of the sickle needlepoint of the working edge is parallel to the working edge of the main comb teeth 2 and is connected with the working edge of the main comb teeth 2 by a horizontal line segment to form the sickle needlepoint. The triangular edges at the back of the tooth have the function of strengthening and holding fibers, so that the fiber transfer process is kept on the layer of the teeth of the doffer needle, the control on the fibers during transfer is increased, the sickle plane in the sickle-shaped needle point is utilized, the reverse advancing direction in operation is utilized, the carried fibers are supported forwards, the falling flowers are eliminated, and the transfer efficiency is greatly improved. The arrangement of the sickle point and the back triangular edge of the working edge doubles the transfer amount of doffer metal card clothing, which is beneficial to improving the yield of the carding machine. The strip-discharging speed can be increased from 80-90m/min to 180-200 m/min.
