Description

Technical Field

[0001] This utility model relates to the field of friction belt production technology, specifically to a core-spun yarn equipment for friction belts. Background Technology

[0002] In the field of friction belt production, core-spun yarn is a key raw material, and its preparation process and equipment performance directly affect the quality and production efficiency of friction belts. In the core step of core-spun yarn preparation—winding cotton yarn onto fiberglass core yarn and then winding it up—current equipment has shown obvious limitations.

[0003] However, current equipment cannot achieve integrated winding of cotton thread around the fiberglass core. Specifically, during the winding process, the coordination between the cotton thread and the fiberglass core is poor, easily leading to uneven winding, knotting, or even separation of the cotton thread from the fiberglass core. This results in unstable core-spun yarn quality and a high defect rate, which not only increases production costs but also affects production efficiency. In addition, as a key component in the core-spun yarn winding process, the ease of disassembly is crucial for improving production efficiency and reducing equipment maintenance costs. However, most current equipment uses bolts to install and fix the spool. While this traditional installation method ensures the stability of the spool during operation to some extent, it brings many inconveniences in actual production. When the spool needs to be replaced, operators must use specialized tools, such as wrenches and screwdrivers, to complete the bolt disassembly and installation work. This not only increases the workload and time cost of operators but also reduces production efficiency. Therefore, we propose a dedicated core-spun yarn equipment for friction belts to solve the above problems. Utility Model Content

A flexible steel rope is fixedly connected to one side of the first T-shaped rod. Grooves are formed on the inner walls of both sides of the mounting base, with a fixed pulley rotatably connected to one side of each groove. The end of the flexible steel rope passes over one side of the corresponding fixed pulley and extends to the outside of the mounting base, where a pull block is fixedly connected.

[0009] Furthermore, the first spring is movably sleeved on the corresponding first T-shaped rod.

[0010] Furthermore, the mounting base is provided with a second T-shaped rod, the end of which extends to the outside of the corresponding mounting base and is fixedly connected to one side of the pull block.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a core-spun yarn device for friction belts, which has the following beneficial effects:

[0017] This invention fixes a cotton thread to a spinning drum by passing one end of a cotton thread guide roller, two rotating rollers, a first pressure roller, and one side of a second pressure roller, and then through a second limiting member. The other end of a fiberglass core thread is passed around a core thread guide roller and a guide rod, through the first limiting member, and then around one side of one of the two rotating rollers and fixed to the spinning drum. The internal rotating mechanism of the device then operates, transmitting power to a rotating shaft. The shaft winds the cotton thread onto the fiberglass core thread via the spinning drum. Under the rotation of the spinning drum, the cotton thread gradually winds around the fiberglass core thread, forming a core-spun yarn structure. This allows the cotton thread to be automatically wound onto the fiberglass, eliminating the need for a traditional roving machine. Pulling the pull block moves the first T-shaped rod via a flexible steel rope, stretching the first spring and causing the first T-shaped rod to separate from the slot. Moving the spinning drum causes the mounting block to separate from the mounting base, making it easy to remove without the need for specialized tools. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example

[0027] like Figure 1-6 As shown in the figure, an embodiment of the present invention discloses a core-spun yarn device for friction belts, comprising a device body 1. A core yarn guide roller 2, a cotton yarn guide roller 3, and two rotating rollers 9 are rotatably connected between the inner walls of both sides of the device body 1. A support rod 4 and a guide rod 8 are provided between the inner walls of both sides of the device body 1. Multiple support arms 5 are provided on the support rod 4. A first pressure roller 6 is rotatably connected to one side of each support arm 5, and two second pressure rollers 7 are rotatably connected to the other side of each support arm 5. Two brackets 11 are fixedly connected to one side of the device body 1. A horizontal plate 12 is welded between the two brackets 11. Multiple rotating shafts 13 are provided on the horizontal plate 12. A mounting base 14 is welded to the top of each rotating shaft 13, and the top of the mounting base 14 movably contacts a... The cable reel 15 has a mounting block 16 at its bottom. The mounting block 16 has slots 17 on both sides. The inner walls of both sides of the mounting base 14 are welded with U-shaped blocks 18. The U-shaped blocks 18 have a first T-shaped rod 19. The first T-shaped rod 19 is engaged with the corresponding slot 17. A first spring 20 is welded between the first T-shaped rod 19 and the corresponding U-shaped block 18. A flexible steel rope 21 is fixedly connected to one side of the first T-shaped rod 19. The inner walls of both sides of the mounting base 14 have grooves 22. A fixed pulley 23 is rotatably connected to one side of the inner wall of the groove 22. The end of the flexible steel rope 21 passes around one side of the corresponding fixed pulley 23 and extends to the outside of the mounting base 14, where a pull block 24 is fixedly connected.

[0028] During use, the cotton thread will gradually wind around the fiberglass core under the rotation of the spool 15, forming a core-spun yarn structure. This allows the cotton thread to be automatically wound onto the fiberglass. A single device is sufficient, eliminating the need for a traditional roving machine. It also facilitates quick disassembly of the spool 15 without the need for specialized tools.

[0029] In use, one end of the cotton thread is wrapped around the cotton thread guide roller 3, the two rotating rollers 9, the first pressure roller 6, and one side of the second pressure roller 7, and then passed through the second limiting member 10 and fixed to the winding drum 15. The other end of the fiberglass core thread is wrapped around the core thread guide roller 2 and the guide rod 8, passed through the first limiting member 29, then wrapped around one side of one of the two rotating rollers 9 and fixed to the winding drum 15. The device body 1 is started, and the internal rotating mechanism begins to operate, transmitting power to the rotating shaft 13. The rotating shaft 13 then winds the fiberglass core thread through the winding drum 15. Because the cotton thread and the fiberglass core thread have already formed a specific relative position during the initial threading process, under the rotation of the winding drum 15, the cotton thread will gradually... The cotton yarn is wound around the fiberglass core to form a core-spun yarn structure, which can automatically wind the cotton yarn onto the fiberglass, eliminating the need for a traditional roving machine. When it is necessary to remove the spool 15, pull the pull block 24. The pull block 24 drives the second T-shaped rod 25 to move and compress the second spring 26. At the same time, the pull block 24 drives the first T-shaped rod 19 to move through the corresponding flexible steel rope 21. During the movement, the first T-shaped rod 19 stretches the corresponding first spring 20, causing the first T-shaped rod 19 to separate from the corresponding slot 17. Then, the spool 15 is moved, causing the spool 15 to drive the mounting block 16 to separate from the mounting base 14, making it easy to remove without the need for professional tools.

[0030] In some embodiments, the first spring 20 is movably sleeved on the corresponding first T-shaped rod 19.

[0031] In some embodiments, the mounting base 14 is provided with a second T-shaped rod 25, the end of which extends to the outside of the corresponding mounting base 14 and is fixedly connected to one side of the pull block 24.

[0032] The second T-shaped rod 25 is set to limit the pull block 24 and prevent the pull block 24 from shifting when it moves.

[0033] In some embodiments, a second spring 26 is welded between one inner wall of the second T-shaped rod 25 and one inner wall of the corresponding mounting base 14, and the second spring 26 is movably sleeved on the corresponding second T-shaped rod 25.

[0034] In some embodiments, a rectangular hole 27 is provided on the top inner wall of the mounting base 14, and the rectangular hole 27 is in active contact with the corresponding mounting block 16.

[0035] The rectangular hole 27 limits the position of the mounting block 16, making it easy to insert the mounting block 16 into the corresponding mounting base 14.

[0036] In some embodiments, a first connecting plate 28 is welded between the inner walls of the two sides of the device body 1, and a plurality of first limiting members 29 are provided on the front side of the first connecting plate 28.

[0037] In some embodiments, a second connecting plate 30 is welded between the inner walls of the two sides of the device body 1, and a plurality of second limiting members 10 are provided on the front side of the second connecting plate 30.

[0038] The second connecting plate 30 serves a supporting function.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
