Abstract
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 tip supporting 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 by installing a spring support assembly on the top of the bare spindle that can support the yarn tube. The bare spindle can support the yarn tube and can effectively prevent the yarn tube from falling off the bare spindle without replacing the special aluminum ingot. The complicated modification steps of replacing the aluminum sleeve spindle are eliminated, which effectively reduces the modification cost and subsequent maintenance cost and improves the practical performance of the bare spindle. Utility Model Content
[0004] The utility model aims to provide a bare-rod spindle tip supporting device for colony to solve the problems raised in the above-mentioned background technology.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] A spindle tip support device for colony bare spindles comprises a bare spindle body, a lower positioning sleeve is fixedly mounted on the bare spindle body, a spring support assembly for supporting a yarn tube is arranged in the lower positioning sleeve, and an upper pressing sleeve is arranged on the upper end of the lower positioning sleeve for pressing the spring support assembly to prevent the spring support assembly from escaping from the lower positioning sleeve.
[0007] As a further preferred solution of the utility model: the spring support assembly includes a connecting plate, which is sleeved on the bare rod spindle body and clamped on the inner upper end of the lower positioning sleeve. A plurality of spring sheets are evenly arranged on the circumference of the connecting plate, and a supporting pressure head is arranged on the outer side of the spring sheet. A plurality of side holes are evenly opened on the outer wall of the lower positioning sleeve. The supporting pressure head passes through the side holes and is located on the outer side of the lower positioning sleeve for pressing against the inner wall of the yarn tube.
[0008] As a further preferred solution of the utility model: a plurality of strip-shaped protrusions are evenly arranged on the inner wall of the lower positioning sleeve, the strip-shaped protrusions are spaced apart from the side holes, the connecting plate is clamped on the upper end of the strip-shaped protrusions, and the spring sheet is clamped between adjacent strip-shaped protrusions.
[0009] As a further preferred solution of the utility model: the upper pressing sleeve is fixedly sleeved on the top of the polished ingot body, and the lower end of the upper pressing sleeve is fixedly inserted in the lower positioning sleeve and contacts with the connecting plate.
[0010] As a further preferred solution of the utility model: the polished rod ingot body and the lower end of the lower positioning sleeve and the upper pressing sleeve are all taper-fitted.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] The spindle tip support device of the bare spindle is provided with an elastic supporting pressure head on the circumferential side of the top of the spindle tip. When the bobbin is put on the bare spindle, the supporting pressure head can press against the inner wall of the bobbin to support the bobbin and prevent the bobbin from falling off the bare spindle. There is no need to replace the traditional bare spindle with a special aluminum sleeve spindle, which reduces the difficulty of modifying the doffing system. By providing a lower positioning sleeve and an upper pressure sleeve, the support device can be assembled by only installing the upper and lower positioning sleeves, the spring support assembly and the upper tooth sleeve on the upper end of the bare spindle body in sequence. The operation is convenient and the subsequent disassembly and maintenance are also convenient. The structural design is scientific and reasonable and the practicability is strong.

DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1
[0023] See also Figure 1-8 The present embodiment provides a spindle tip supporting device for colonization, comprising a spindle body 1, a lower positioning sleeve 2 fixedly mounted on the spindle body 1, a spring support assembly 4 for supporting a yarn tube 13 being arranged in the lower positioning sleeve 2, and an upper pressing sleeve 6 for pressing the spring support assembly 4 being arranged at the upper end of the lower positioning sleeve 2, so as to prevent the spring pressing support assembly 4 from escaping from the lower positioning sleeve 2.
[0024] Specifically, Figure 5 As shown, the spring support assembly 4 includes a connecting plate 10, which is sleeved on the polished ingot body 1. Specifically, a center hole 11 corresponding to the polished ingot body 1 is opened on the connecting plate 10, and the connecting plate 10 is clamped on the inner upper end of the lower positioning sleeve 2. A plurality of spring sheets 12 are evenly arranged around the connecting plate 10, and a supporting pressure head 5 is arranged on the outer side of the spring sheet 12. Preferably, the supporting pressure head 5 is located at the lower end of the spring sheet 12, as shown in FIG. Figure 3 , Figure 4 as well as Figure 8 As shown, a plurality of side holes 3 are evenly opened on the outer wall of the lower positioning sleeve 2 , and the supporting pressing head 5 passes through the side holes 3 and is located outside the lower positioning sleeve 2 for pressing against the inner wall of the yarn tube 13 .
[0025] In order to better ensure the stability of the spring support assembly 4 in the lower positioning sleeve 2, as shown in FIG. Figure 4 As shown, a plurality of strip-shaped latching protrusions 7 are evenly arranged on the inner wall of the lower positioning sleeve 2, and the strip-shaped latching protrusions 7 are spaced apart from the side holes 3. A clamping platform 8 for supporting the connecting plate 10 is formed at the upper end of the strip-shaped latching protrusions 7, so that the connecting plate 10 can be clamped on the upper end of the strip-shaped latching protrusions 7, and positioning grooves 9 corresponding to the spring sheets 12 are formed between adjacent strip-shaped latching protrusions 7, so that the spring sheets 12 can be clamped between adjacent strip-shaped latching protrusions 7, thereby effectively ensuring the stability of the supporting pressure head 5 in the side hole 3.
[0026] like Figure 3 as well as Figure 6 As shown, the upper pressing sleeve 6 is fixedly sleeved on the top of the bare rod ingot body 1, and the lower end of the upper pressing sleeve 6 is fixedly inserted in the lower positioning sleeve 2 and contacts the connecting plate 10. Specifically, as a conventional setting, a plug 14 corresponding to the upper end of the lower positioning sleeve 2 is provided at the bottom of the upper pressing sleeve 6, and the plug 14 is inserted in the lower positioning sleeve 2 and contacts the connecting plate 10.
[0027] It should be noted that, as common knowledge familiar to those skilled in the art, since the bare rod ingot body 1 is a tapered rod rather than a cylinder in actual application, the fit between the bare rod ingot body 1 and the lower end of the lower positioning sleeve 2 and the upper pressing sleeve 6 is preferably a taper fit, and the lower positioning sleeve 2 and the upper pressing sleeve 6 are put on the bare rod ingot body 1 and pressed tightly to achieve their installation. This fitting design is a conventional design familiar to those skilled in the art and will not be repeated in this application.
[0028] like Figure 7 as well as Figure 8 As shown, after the spindle tip support device is assembled, the yarn tube 13 is mounted on the bare spindle body 1, and the support pressure head 5 can press against the inner wall of the yarn tube 13 to prevent the yarn tube 13 from falling off, thereby ensuring that the yarn tube 13 has sufficient supporting force and that weak twist will not occur during the spinning process, so that the required spinning effect can be achieved.
[0029] It should be noted that the above embodiments are only specific and clear descriptions of the technical solutions and technical features of the present application.
