Description

Technical Field

[0001] The utility model relates to the technical field of bare-rod spindles of spinning machines, in particular to a bare-rod spindle supporting yarn-breaking device for colonization. Background Art

[0002] At present, the short spinning machines used in the market are almost all equipped with bare spindles as standard. However, in actual applications, since the bobbin is specially used with aluminum ingots, it is necessary to transform the traditional doffing system and replace all bare spindles with aluminum sleeve spindles to ensure sufficient support for the bobbin. This not only causes waste, but also prolongs the transformation cycle, affects production, and greatly increases the transformation cost. In subsequent maintenance, the entire aluminum sleeve spindle needs to be disassembled and maintained, which increases the difficulty of maintenance.

[0003] To this end, we modified the original bare spindle and installed spring support components that can support the yarn tube at the top and tail of the bare spindle, so that the bare spindle can support the yarn tube and cooperate with the thin-walled yarn tube specially made for aluminum ingots to ensure that no weak twist occurs during the spinning process; at the same time, a tail yarn breaking device was installed at the tail of the bare spindle to increase the yarn retention rate, reduce the labor intensity of workers, and reduce the time and cost of the transformation of the spun yarn collection system.

Figure 3 , Figure 5As shown, the cutter head fixing sleeve 2 is mounted on the fixing sleeve clamping platform 6, and its bottom is in contact with the retaining ring 7; the cutter head fixing sleeve 2 and the fixing sleeve clamping platform 6 preferably adopt a tight fit, that is, an interference fit, and other conventional fixed connection methods can also be adopted, which will not be described in detail in this application; at the same time, Figure 7 As shown, a yarn cutting knife 17 is fixedly arranged on the yarn cutting knife disc 3, and a plurality of yarn cutting grooves 18 corresponding to the yarn cutting knife 17 are evenly opened on the yarn cutting knife disc 3 to improve the yarn retention rate.

[0035] In order to achieve the replacement of the yarn breaking knife 17, preferably, the yarn breaking knife disc 3 is detachably connected to the knife disc fixing sleeve 2. Preferably, a connecting portion 23 is provided at the head of the knife disc fixing sleeve 2, preferably, it is a connecting ring for threaded connection with the yarn breaking knife disc 3, and the yarn breaking knife disc 3 is screwed onto the connecting portion 23. Other conventional connection methods familiar to those skilled in the art may also be used, and this application will not go into details.

[0036] Further, if Figure 3 as well as Figure 5 As shown, a spring assembly fixing sleeve 5 for fixing the first bobbin supporting spring assembly 4 to the spindle rod 1 is arranged outside the first bobbin supporting spring assembly 4; specifically, as Figure 8 As shown, the first bobbin support spring assembly 4 includes a first connecting ring 13 sleeved on the spindle rod 1, the first connecting ring 13 is provided with a first through hole 16 corresponding to the spindle rod 1, a plurality of first spring sheets 14 are evenly arranged around the first connecting ring 13, and a first supporting pressure head 15 is arranged outside the first spring sheet 14, as shown in FIG. Fig.16 As shown, the first supporting pressure head 15 passes through the spring assembly fixing sleeve 5 and is in close contact with the inner wall of the yarn tube 12; Figure 5 , Fig. 9 , Fig.10 As shown, the spring assembly fixing sleeve 5 is clamped on the spindle rod 1, and a plurality of first strip-shaped clamping protrusions 19 are evenly arranged on the lower side of the inner wall of the spring assembly fixing sleeve 5, and a plurality of first side holes 21 are evenly opened on the outer wall of the spring assembly fixing sleeve 5.

A second side hole 29 communicating with the second positioning groove 28 is opened on the outer wall of the lower positioning sleeve 24, and the second bobbin supporting spring assembly 25 includes a second connecting ring 30, and a second through hole 33 corresponding to the spindle rod 1 is opened on the second connecting ring 30, and a plurality of second springs are evenly arranged around the second connecting ring 30. The second spring sheet 31 is provided with a second supporting press head 32 on the outer side of the second spring sheet 31. The second bobbin supporting spring assembly 25 is provided in the lower positioning sleeve 24. The second connecting ring 30 is mounted on the upper end of the second strip-shaped convex 27. The second spring sheet 31 is located in the second positioning groove 28. The second supporting press head 32 passes through the second side hole 29 and is used to be in close contact with the inner wall of the bobbin 12 to support the bobbin 12. At the same time, an upper pressing sleeve 26 for pressing the second bobbin supporting spring assembly 25 is also provided on the top of the spindle rod 1. Fig.14 As shown, the upper pressing sleeve 26 is sleeved on the top of the spindle rod 1, and a plug 34 is provided at the bottom of the upper pressing sleeve 26. The plug 34 is inserted into the top of the lower positioning sleeve 24 and presses the second connecting ring 30 to fix the second yarn tube supporting spring assembly 25.

[0041] When assembling the bobbin 12, Fig.15 as well as Fig.16 As shown, the yarn tube 12 is mounted on the spindle rod 1, and its tail end is inserted into the tube gap 11. The first supporting press head 15 leaking out of the spring assembly fixing sleeve 5 and the second supporting press head 32 leaking out of the lower positioning sleeve 24 can tightly press against the inner wall of the yarn tube 12 to prevent the yarn tube 12 from falling off. Its specific working principle is the working principle of a conventional spinning frame familiar to those skilled in the art, and will not be repeated in this application.
