During the production of quilt spinning yarns, slivers or tops, etc., are regularly accommodated in a certain receipt-shaped portion for the next process. Special equipment for the textile industry on the winder. As the last process of spinning and the first process of weaving, winding is the link between the past and the next.“bridge”Therefore, it occupies an important position in the textile field.
Grinder A spinning machine that turns fiber strands into rovings. The main function is to draft and twist, and to wind the roving into a certain package to meet the processing requirements of the spinning frame. During the spinning process of the spinning frame, the semi-finished roving or sliver is drafted, twisted, and wound into a spinning machine. The combed sliver and the needle-carding machine combine the sliver, the needle row is drafted to improve the sliver structure, and the roving is further spun into spun yarn on the ring spinning frame, which is the main spinning machine.
When the formed coiler is completed, the mentioned winding mechanism for producing quilt coils. In the production of quilt production lines, in order to improve the labor and social productivity of the enterprise and the utilization rate of equipment resources, large-diameter cans are used, and products with the largest market capacity in China are required to be included in the geometric development space formed by a certain package size. Because the bag is loose, the fiber is small, and the strength of the strip is low, when the strip is in and out of the strip, if it is subjected to a large tensile force, accidental drafting or breakage will occur.
Therefore, in addition to the above requirements, it is required that the ring strips are formed correctly, the layers are clear, and the ring strips are not entangled with each other. The following mainly introduces the design of the cotton spinning sliver mechanism. In the cotton spinning carding machine, the sliver product on the quilt production line generally passes through the edge of the coil, so that the sliver is stored in the brocade in a cycloid shape.
Because 2-32 is a drawing of the a187a card return frame. When the sliver is pressed by the small roller 2, it enters the sliver 4 through the inclined tube 3 of the reel. Silver is stored in cylinders in a certain shape.
The return reel rotates at the same speed, and the absolute trajectory of the inclined tube is circular in space. It is because there is an eccentric distance e between the gold ring and the silver ring, and the speed of the silver cylinder and the gold ring is the same, so the relative trajectory of the cotton sliver in the sliver is cycloid, forming an air hole in the center of the sliver. When the size of the sliver is constant, such as changing the eccentricity e value, the shape of the sliver has a small sliver (the diameter of the sliver of the sliver, the radius of the sliver) and the large sliver (the diameter of the sliver track is larger than the radius of the sliver) points.
The design of the coiling mechanism should meet the following technical requirements: (1) The coiling is formed normally, that is, the air holes in the sliver can penetrate through the entire height, the solid layers are clear, and the two adjacent slivers are arranged closely without Overlapping, the sliver can be smoothly drawn out in the next straw process. Figure: Put the outer garden in order, and there is no excessive gap at the edge of the bar. (2) The amount of brocade rolled leather is large, which reduces the time of changing cans and improves the labor and social productivity of the enterprise.
