Description
Technical Field
The invention relates to a warp beam clamping disc of a warp knitting machine, in particular to an axial conical anti-loosening warp beam clamping device of the warp knitting machine.
Background
The raw material of the warp knitting machine is that the yarn is wound on the sectional warp knitting pan heads through warping, then a group of warp knitting pan heads (4-10 are unequal to form a group) is penetrated on a warp beam with the diameter of 152mm, in order to achieve the effect that the group of pan heads can synchronously run without loosening and relative sliding between the pan heads, two ends of the warp beam need to be clamped by a pan head clamp, the inner diameter of the pan head clamp is also 152mm, and the currently used pan head clamp completely increases the friction force by increasing the clamping force to prevent the pan head clamp from axially sliding on the warp beam. However, under the inertia effects of warp beam operation, sudden stop and the like, the pan head clamp can slide axially, so that the pan head can be loosened, and then the relative sliding between the pan heads can occur, and the sliding can cause defective products with cloth cover problems. Therefore, the prior art has the problem that the clamping effect is not ideal.
