Embodiment Construction

[0007] In the specific implementation, a kind of opening beater with a specific shape is obtained by casting technology. Its material and main part are the same as ordinary truncated conical angle nails, and its surface is made with several circles of special external convex threads along the axial direction. The thread interval is 1-2cm, and the graph of the special convex thread along the beater axis section is formed by the intersection of the curve sin(x) and the curve sin(x-π / 2) with the x-axis in the interval [π / 2, π]. The graphics, the coordinate axis length unit used for calculation is determined by the length of the truncated conical angle nail, so that 1 / 10 of the length of the beater can be the coordinate axis length unit "1", and a section of it can be threaded in the metalworking workshop. The screw thread specification matches the screw thread specification of the roller, and is still connected with the roller of the cotton opener by means of bolt connection. Duri...

Abstract

The invention provides a cotton-slitting beater, which is applied to a step cleaner and comprises the following manufacturing process that: the cotton-slitting beater with a specific profile is manufactured by adopting a casting technique, wherein the main part of the cotton-slitting beater is the same as the common truncated cone bradnail; the surface of the cotton-slitting beater is provided with a plurality of loops of special male threads along the axial direction at intervals of 1 to 2 cm; the figure of the special male thread along the axial section of the beater is formed by intersecting a curve sin(x) and a curve sin(x-pi / 2) with x axis at an interval [pi / 2, pi]; during cotton slitting, the cotton-slitting beater can effectively cut into a cotton block from a plurality of positions; along with the rotation of the beater, the cotton block is torn in a larger range; and compared with the common truncated cone bradnail beater, the cotton-slitting beater of the invention has more acute cotton-slitting process and can improve the cotton-slitting efficiency of the step cleaner to a great extent.

Description

Technical field [0001] The invention relates to an opener beater in the cotton opening and cleaning process, in particular to an opener beater capable of improving the cotton opening efficiency in a six-roller opener. Background technique [0002] In the cotton opening and cleaning process, the cotton opener uses the cotton opener to drive the cotton block to collide with the dust grid at high speed, so as to play the role of loosening and removing impurities. , the types of cotton opening beaters are also different. At present, the main cotton opening beaters are of the following types: 1. Truncated conical angle nail beaters, the arrangement is, four rows of truncated cone angle nails, 7-8 pieces / row, distributed on the surface of the opener roller, the structure is relatively simple; 2. Porcupine beater, which is characterized by 19 discs, each disc has 12 rectangular blades, irregular arrangement, uniform blow, φ610mm, 480-600r / min, if the speed is high, the opening ...
