Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of twist preventers, and more specifically to a ceramic twist preventer. Background Art
[0002] At present, the spinning technologies mainly include rotor spinning and ring spinning. The twist preventer is an essential component applied to a rotor spinning machine, which includes a base and a ceramic body coaxially implanted therein, and the ceramic body is in a funnel-shaped structure.
[0003] Under the traditional process, the assembly structure between the ceramic body and the base is to coat glue between the two to bond them. However, such a bonding structure is easy to fall off. During the use of the twist preventer, high temperature will be generated, resulting in the degumming and separation of the ceramic body and the base, which will damage the heart of the spinning machine and even pose a fire hazard in serious cases, bringing huge losses to production enterprises. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a ceramic twist preventer, which improves the connection stability between the ceramic body and the connecting base, and effectively avoids damaging the spinning machine or even causing a fire hazard due to the falling off of the ceramic body.
[0005] In order to achieve the above purpose, the technical solution of the utility model is as follows:
[0006] A ceramic twist preventer includes a connecting base and a ceramic body. The ceramic body is in a funnel-shaped structure. A placement cavity matching the ceramic body is opened inside the connecting base. A through groove communicating to the outside of the connecting base is opened on the side wall of the placement cavity. A plug rod is slidably connected in the through groove. A slot corresponding to the plug rod is opened on the side wall of the ceramic body. A plug rod limiting component is arranged on the outer side wall of the connecting base.
[0007] Further, a vertical groove communicating with the slot is opened on the side wall of the connecting base; the plug rod limiting component includes a limiting rod slidably connected in the vertical groove. A through hole corresponding to the limiting rod is opened on the plug rod. The limiting rod is inserted into the through hole. A lifting rod is fixedly connected to the top of the limiting rod.
[0008] Further, a push-pull plate is fixedly connected to one end of the plug rod located outside the connecting base.
[0009] Further, multiple groups of the through groove, the plug rod, the slot and the plug rod limiting component are provided and are evenly distributed around the ceramic body.
[0010] Further, the ceramic body is made of finely polished ceramic.
[0011] Compared with the prior art, the beneficial effects of the utility model:
[0012] By providing a through groove on the side wall of the placement cavity of the connection base, the present utility model enables the insertion rod to cooperate with the slot on the side wall of the ceramic body, thus changing the traditional glue bonding method. This mechanical connection structure is not prone to debonding and separation problems in high-temperature environments, improving the connection stability between the ceramic body and the connection base, effectively avoiding the risk of damaging the spinning machine or even causing a fire hazard due to the detachment of the ceramic body, ensuring production safety, and reducing enterprise losses.

[0016] As Figure 1 and Figure 2 shown, a ceramic twist stopper includes a connection base 1 and a ceramic body 2. The ceramic body 2 has a funnel-shaped structure. The connection base 1 is internally provided with a placement cavity 101 that matches the ceramic body 2. A through groove 102 communicating with the outside of the connection base 1 is provided on the side wall of the placement cavity 101. An insertion rod 3 is slidably connected in the through groove 102. A slot 201 corresponding to the insertion rod 3 is provided on the side wall of the ceramic body 2. An insertion rod limiting component is provided on the outer side wall of the connection base 1.
[0017] A vertical groove 103 communicating with the slot 201 is provided on the side wall of the connection base 1; the insertion rod limiting component includes a limiting rod 4 slidably connected in the vertical groove 103. A through hole 301 corresponding to the limiting rod 4 is provided on the insertion rod 3. The limiting rod 4 is inserted into the through hole 301. A pull rod 5 is fixedly connected to the top of the limiting rod 4.
[0018] One end of the insertion rod 3 located outside the connection base 1 is fixedly connected with a push-pull plate 6.
[0019] The through groove 102, the insertion rod 3, the slot 201, and the insertion rod limiting component are all provided in multiple groups and are evenly distributed around the ceramic body 2; so that the connection force between the ceramic body 2 and the connection base 1 is evenly distributed on the circumference of the ceramic body 2. In this way, during the working process, the ceramic body 2 can evenly bear the forces from all directions, avoiding the problem of connection failure caused by excessive local stress, and further improving the stability of the overall structure.
[0020] The ceramic body 2 is made of precisely polished ceramic; the surface of the ceramic after precise polishing is smoother. During the spinning process, the friction between the yarn and the ceramic body 1 is more uniform, reducing damage to the yarn and being beneficial to improving the spinning quality. At the same time, precisely polished ceramic has high wear resistance, which can extend the service life of the ceramic body 1 and reduce the equipment maintenance cost.
[0021] Working principle:
[0022] Installation process: Place the ceramic body 2 into the placement cavity 101 of the connection base 1, aligning the slot 201 of the ceramic body 2 with the through slot 102 of the connection base 1; then push the insertion rod 3 so that the insertion rod 3 slides along the through slot 102 and inserts into the slot 201 of the ceramic body 2; then slide the limit rod 4 along the vertical slot 103 and insert it into the through hole 301 of the insertion rod 3 to limit the insertion rod 3, completing the connection and installation of the ceramic body 2 and the connection base 1.
[0023] Working process: When the cup spinning machine is working, the yarn passes through the ceramic body 1 (funnel-shaped structure). Since the ceramic body 1 is firmly connected to the connection base 2, it can stably provide resistance to the yarn and achieve the normal yarn twisting resistance function.
[0024] Disassembly process: When maintenance of the yarn twisting head or replacement of the ceramic body 1 is required, pull up the lifting rod 5 upwards so that the limit rod 4 disengages from the through hole 301 of the insertion rod 3, and then pull the insertion rod 3 outwards through the push-pull plate 6 so that the insertion rod 3 withdraws from the slot 201 of the ceramic body 2, thereby enabling the ceramic body 2 to be taken out from the placement cavity of the connection base 1.
[0025] The present utility model abandons the traditional glue bonding method that is prone to degumming, and adopts a mechanical connection structure, avoiding the risk of damaging the spinning machine or even causing a fire due to the degumming and separation of the ceramic body 2 and the connection base 1, providing a safer production environment for production enterprises; the combined use of multiple mechanical connection structures and the uniform distribution of multiple groups of components make the connection between the ceramic body 2 and the connection base 1 more stable and reliable, ensuring the stable operation of the yarn twisting head during the spinning process.
[0026] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model.
