Problems solved by technology

[0005] In actual use, the use of rubber rings can better output frictional resistance during the rotation of the bobbin, but it will also bring a lot of inconvenience
On the one hand, the apron is made of rubber, which is soft in summer and hard in winter. When the deformation of the apron is certain, the output friction force is quite different, which is not convenient for the stable control of yarn tension.
On the other hand, the rubber ring will gradually wear out during long-term use, its deformation degree will gradually decrease, and the output friction force will also become smaller, so it needs to be replaced regularly

Embodiment

[0033] A radial unwinding core for section warping machines, such as figure 2 As shown, the spindle bar 5 erected on the frame 7 is included. Spindle bar 5 is arranged along the horizontal direction, and damping disc 1 , barrel core body 6 and end cap 2 are sheathed on it. The damping disc 1 , the barrel core body 6 and the head 2 are arranged in sequence, all of which are coaxial with the spindle rod 5 , and the damping disc 1 is closest to the frame 7 .

[0034] like figure 2 As shown, a limiting plate 13 is integrally formed on the outer wall of the damping disc 1, the limiting plate 13 is annular, and its axis coincides with the axis of the damping disc 1, and the limiting plate 13 is located on the damping disc 1 close to the position of the limiting plate 13. one end. The end face of the bobbin 8 facing the frame 7 is against the limit plate 13 and does not contact the frame 7 during the rotation.

[0035] like figure 2 As shown, an annular groove 11 is formed on...

Abstract

The invention belongs to the technical field of textile machinery, and discloses a radially unwinding core for a section warping machine. The key points of the technical solution are to include a damping disc and a head, and an O-shaped core is sleeved on the damping disc. The ring also includes reeds arranged on the side of the head, the reeds are arranged along the circumference of the head, the cross section of the reed is arc-shaped, the middle part of the reed is arched away from the head, and is aligned with the inner side of the bobbin The walls are offset, and the rubber apron is replaced by a metal reed, which is less affected by temperature changes, has high wear resistance, and can output friction force stably.

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to a radial unwinding core for a section warping machine. Background technique [0002] Warping is to wind the bobbins on the pan head in parallel, constant speed and neatly under the same tension according to the number and length of the yarns required by the process. It is a crucial preparation process in warp knitting. A warping machine is required for this process. [0003] The unwinding bobbin core can be said to be the starting point of the warping machine, where the yarn is unwound from the original bobbin, and wound on the warp beam after steps such as split twisting and sizing. In order to keep the yarn in a tensioned state, the yarn pulling yarn drum needs to be subjected to certain resistance when it rotates, and this resistance is realized by means of the dynamic friction force between the yarn drum and the core. [0004] There is an existing yarn unwinding c...
