Description

Technical Field

[0001] The present application relates to the technical field of textile machine bobbins, and in particular to a bobbin assembly that is easy to replace. Background Art

[0002] A textile machine is a piece of mechanical equipment specially used to process raw materials such as fiber, cotton, linen, wool, and artificial fiber. It can use these raw materials for textile processing and eventually make various fabrics and textiles. The textile machine bobbin is a component on the textile machine. Its main function is to assist in collecting yarn during the spinning process and winding it into a neat bobbin. After the yarn is processed by the spindle on the spinning wheel, it will be wound onto the bobbin, which is convenient for storage and transportation. Generally, a textile machine will be equipped with multiple bobbins. When the yarn production is completed, these bobbins need to be removed and replaced.

[0003] Existing Chinese patent application number CN111646318B, "A Textile Machine Bobbin Assembly Easy to Replace", includes a through shaft, a sliding rod, a limit spring, etc. When disassembling the bobbin, it is first necessary to engage the limit block with the fixed head, and then move the sliding sleeve to press the fixed head down, the front end protrusion of the sliding sleeve is engaged with the slot, and the sliding sleeve is docked with the outer sleeve. At this time, the bobbin loses its fixing function and can be taken out.

[0004] In the above device, because the limit block and the fixed block are located at one end of the spool, and the sliding sleeve is located at the other end of the spool, in the above device, when disassembling the spool, corresponding operations need to be performed at both ends of the spool. When installing, it is also necessary to control the limit blocks, fixed blocks and sliding sleeves at both ends of the spool. Therefore, the operation process is still relatively cumbersome. Moreover, a textile machine is usually equipped with multiple spools. Each spool needs to be operated at both ends when it is disassembled and assembled. The workload is still large when all the spools are replaced together. Summary of the Invention

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-9 This application is described in further detail.

[0030] Reference Figure 1 and Figure 2 A reel assembly that is easy to replace includes a rotating shaft 1. The rotating shaft 1 can be installed on a textile machine and driven by a motor. A supporting cylinder 2 is fixed to one end of the rotating shaft 1 by welding. The supporting cylinder 2 is a hollow cylindrical structure. A reel 3 is sleeved on the outside of the supporting cylinder 2.

[0031] The center shaft 5 is fixedly connected to the interior of the bearing cylinder 2, and a movable plate 6 is provided between the center shaft 5 and the bearing cylinder 2.

[0032] Because the spool 3 needs to rotate when in use, the rotating shaft needs to be fixed on the outside of the carrying cylinder 2, and the rotating shaft 1 drives the carrying cylinder 2 and the spool 3 to rotate together;

[0033] Therefore, a pushing mechanism 9 is provided on the central shaft 5 for pushing the movable plate 6 to move outward, and an upper limit block 604 and a lower limit block 605 are provided on the movable plate 6 for fixing the bobbin 3. A limiting hole 201 for accommodating the upper and lower blocks and the lower limit block 605 is provided on the supporting cylinder 2. When the pushing mechanism 9 pushes the movable plate 6 to move outward, the upper limit block 604 and the lower limit block 605 extend from the limiting hole 201 to limit and fix the two ends of the bobbin 3.

[0034] Referring to Figure 3, two upper and lower fixed mounting rings 7 are fixedly connected to the central axis 5 by welding, and the outer sides of the two fixed mounting rings 7 are hingedly connected to the auxiliary oblique support rod 8. At the same time, the other end of the auxiliary oblique support rod 8 is hinged to one side of the movable plate 6. Because the movable plate 6 is a long strip structure, and the pushing mechanism 9 of the movable plate 6 is located in the upper half of the movable plate 6, the upper and lower ends of the long strip movable plate 6 are synchronized in movement through the cooperation of the upper and lower fixed rings and the auxiliary oblique support rod 8 to prevent it from bending during use, which causes the lower limit block 605 at the lower end to be unable to extend.

[0035] Reference Figure 4 and Figure 5 Specifically, the pushing mechanism 9 includes a lifting cylinder 901, a movable mounting ring 902, a driving oblique support rod 903, a threaded shaft 904, and a rotating ring 905. The upper end of the lifting cylinder 901 is welded and fixed to the threaded shaft 904. A groove is provided on the outer side of the lifting cylinder 901. At the same time, the movable mounting ring 902 is rotatably connected in the groove through a plane bearing. That is, when the lifting cylinder 901 moves up and down, it will also drive the movable mounting ring 902 to move up and down, and the movable mounting ring 902 can rotate. At the same time, the two ends of the driving oblique support rod 903 are rotatably connected to the movable mounting ring 902 and the movable plate 6 respectively, and as shown in FIG. Figure 4As shown, the installation direction of the driving oblique support rod 903 is opposite to the installation direction of the auxiliary oblique support rod 8;

[0036] The lifting cylinder 901 is sleeved on the central shaft 5. An inner limiting groove 906 is provided on the central shaft 5. A corresponding inner limiting strip 907 is provided on the inner side wall of the lifting cylinder 901. The inner limiting strip 907 is slidably connected in the inner limiting groove 906, that is, the lifting cylinder 901 can move up and down along the central shaft 5.

[0037] Because the upper end of the lifting cylinder 901 is fixedly connected to the threaded shaft 904, in order to enable the lifting cylinder 901 and the movable mounting ring 902 to move up and down along the central axis 5, the lower end of the threaded shaft 904 is also provided with a hole, that is, the lifting cylinder 901 and the threaded shaft 904 are both sleeved on the central axis 5, and the upper end of the threaded shaft 904 extends out of the supporting cylinder 2.

[0038] Because the rotation of the threaded shaft 904 needs to be controlled, a rotating ring 905 is rotatably connected at the upper end outlet of the supporting cylinder 2, and a rotating rod is connected to the outer side of the rotating ring 905 to facilitate the rotation control of the rotating ring 905, and the inner ring of the rotating ring 905 is provided with a thread, and the rotating ring 905 is threadedly connected to the threaded shaft 904; in summary, because the threaded shaft 904 can only move up and down together with the lifting cylinder 901 and cannot rotate, when the rotating ring 905 rotates, it will drive the threaded shaft 904, the lifting cylinder 901 and the movable mounting ring 902 to move up and down along the central axis 5.

[0039] Reference Figure 6 When the movable mounting ring 902 moves downward, the driving inclined support rod 903 rotates and opens, pushing the movable plate 6 outward. Therefore, the upper limit block 604 and the lower limit block 605 on the movable plate 6 are driven to move outward. At the same time, because the movable plate 6 mainly relies on the rotation of the driving inclined support rod 903 and the auxiliary inclined support rod 8 to move outward, the movable plate 6 will also move downward for a distance when it moves outward, while the upper limit block 604 and the lower limit block 605 only need to move outward, and do not need to move up and down. Because in order to prevent the upper limit block 604 and the lower limit block 605 from moving up and down, two upper and lower sliding grooves 601 are provided on the movable plate 6, and a guide rod 602 is installed in the sliding groove 601. At the same time, the upper limit block 604 and the lower limit block 605 are respectively slidably connected in the upper and lower sliding grooves 601 through the guide rod 602, and a spring 603 is also sleeved on the outer side of the guide rod 602.

[0040] On the inner wall of the bearing tube 2 and on both sides of the movable plate 6, a limit plate 10 is fixedly connected ( Figure 2At the same time, a dovetail groove 13 is provided on the opposite side of the upper limit block 604 and the lower limit block 605, and a slider 12 is slidably connected in the dovetail groove 13. The slider 12 is fixedly connected to the fixing frame 11, and the fixing frame 11 is fixedly connected to the limit plate 10. Because the position of the slider 12 is fixed, the upper limit block 604 and the lower limit block 605 can only move horizontally.

[0041] Reference Figure 7-Figure 9 Because the upper limit block 604 and the lower limit block 605 are fixed in the position extending from the limit hole 201, it is necessary for the spool 3 to be placed in the specified position of the carrying tube 2. Therefore, a baffle 4 is fixedly connected to the carrying tube 2. When the spool 3 is installed, the baffle 4 can serve as a limit and blocking function at one end of the spool 3. At the same time, a card interface 401 is provided on the baffle 4, and a positioning block 301 is fixedly connected to the end of the spool 3. When the spool 3 is installed, the positioning block 301 can pass through the card interface 401. A square positioning hole 302 is provided on the positioning block 301. When the positioning block 301 on the spool 3 passes through the card interface 401 on the baffle 4, its square positioning hole 302 corresponds to the limit hole 201, that is, when the lower limit block 605 extends out of the limit hole 201, it will be inserted into the positioning hole 302, thereby fixing the spool 3.

[0042] When the upper limit block 604 is extended, the upper end of the spool 3 is just stuck to the upper end of the spool 3. Therefore, the upper limit block 604 and the lower limit block 605 cooperate to fix the spool 3 from both ends.

[0043] The implementation principle of this embodiment is:

[0044] (1): When installing the spool 3, first place the end of the spool 3 with the positioning block 301 downward, and use the outer limit strip 303 on the inner wall of the spool 3 to cooperate with the outer limit groove 202 on the outer wall of the carrier tube 2 to sleeve the spool 3 on the carrier tube 2, and insert the positioning block 301 at the lower end of the spool 3 into the card interface 401 on the baffle 4,

[0045] (2): Then control the rotating ring 905 to rotate. Because of the cooperation between the inner limit strip 907 on the inner wall of the lifting cylinder 901 and the inner limit groove 906 on the central axis 5, when the rotating ring 905 rotates, it will drive the threaded shaft 904 and the lifting cylinder 901 to move downward along the central axis 5. At this time, the driving inclined support rod 903 on the side of the movable mounting ring 902 opens, pushing the movable plate 6 to move outward, and the movable plate 6 drives the upper limit block 604 and the lower limit block 605 to move outward. Therefore, the upper limit block 604 and the lower limit block 605 extend from the limit hole 201 on the supporting cylinder 2, and the lower limit block 605 is inserted into the positioning hole 302 on the positioning block 301, clamping the spool 3 from the bottom end, and after the upper limit block 604 extends, it blocks the spool 3 from the top end, and the textile spool 3 is taken out from the top end. When working, the spool 3 is driven to rotate together through the rotating shaft 1 and the supporting cylinder 2.

[0046] (3): When removing the spool 3, it is only necessary to rotate the rotating ring 905 in the reverse direction to retract the upper limit block 604 and the lower limit block 605 back into the supporting tube 2. At this time, it is convenient to remove the spool 3 from the supporting tube 2 and replace the new spool 3. In summary, the device has a simple structure and is easy to operate. It is only necessary to rotate the rotating ring 905 in the forward and reverse directions to complete the fixing and then loosening of the spool 3, which makes it more convenient for the operator to replace the spool 3 and improves work efficiency.

[0047] The embodiments of this specific implementation method are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
