Description

Technical Field

[0001] The utility model belongs to the technical field of rotor spinning machines, and specifically relates to a yarn guide device for a rotor spinning machine. Background Art

[0002] With the continuous development of textile technology, rotor spinning machines have been widely used in the textile industry. As a new type of spinning equipment, rotor spinning machines have quickly become an important choice for textile enterprises to improve production efficiency and reduce energy consumption due to their significant advantages such as high speed, high efficiency, and energy saving. In today's highly competitive textile market, these advantages of rotor spinning machines have enabled them to stand out among numerous spinning equipment and become an indispensable part of spinning machines.

[0003] The deficiencies of the existing yarn guide device for rotor spinning machines are as follows: In the existing technology, the yarn guide nozzle and the yarn guide base are mostly connected by fixed welding. This makes it necessary to directly replace the entire base once the base is damaged during use. At present, when replacing the base, due to its one-piece welded formation, it takes a lot of time and manpower. Moreover, when replacing the base, since the yarn guide nozzle is fixedly welded to the base, even if the yarn guide nozzle may not be damaged, it has to be replaced together, which undoubtedly causes great waste. Summary of the Utility Model

[0004] To solve the problems raised in the above background art, the utility model provides a yarn guide device for a rotor spinning machine, which includes a yarn guide rod, an A base and a B base assembled outside the yarn guide rod, and a yarn guide nozzle structure located at the top of the B base. A quick installation structure is provided in the middle of the A base and the B base.

[0005] The yarn guide nozzle structure includes a limiting groove opened at the top of the B base, a guiding rod inserted into the inner wall of the limiting groove, and threaded sleeves fixedly installed on the front and back of the B base. A threaded rod is rotatably connected to the inner wall of the threaded sleeve. One end of the threaded rod close to the B base is rotatably connected to an abutting block through a bearing, and a yarn guide nozzle is fixedly installed at the top of the guiding rod.

[0006] Preferably, the quick installation structure includes an installation groove opened on the surface where the B base and the A base are in contact with each other, and a plug block inserted into the inner wall of the installation groove and fixedly connected to the A base.

[0007] Preferably, installation blocks are provided on the surfaces where the A base and the B base are in contact with each other, and installation holes are opened in the inner walls of the installation blocks.

[0008] Preferably, a screw rod is rotatably connected to the inner wall of the installation hole, and a nut is threadedly connected to the outer wall of the screw rod.

[0009] Preferably, a through groove communicating with the threaded sleeve is formed in the inner wall of the limiting groove, and the abutting block is in contact with the guide rod.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] Through the design of the yarn guide nozzle structure and the quick installation structure, the A base and the B base are plugged together to form a complete base. This method not only greatly reduces the time required for replacing the base, improves production efficiency, but also reduces maintenance costs. Secondly, when a single yarn guide nozzle is damaged and a new one needs to be replaced, only need to bend the two guide rods towards the middle so that they can be plugged into the inner wall of the limiting groove. When plugged into the inner wall of the limiting groove, the guide rod rebounds by its own rigidity and is clamped and fixed between the through groove and the limiting groove, thus realizing the effect of quickly installing the yarn guide nozzle. This design not only facilitates the operation and replacement by the operator, but also ensures the stability and reliability of the yarn guide nozzle after installation.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Such asFigures 1 to 5 As shown in the figure, the present utility model provides a yarn guide device for a rotor spinning machine, which includes a yarn guide rod 1, an A base 2 and a B base 21 assembled outside the yarn guide rod 1, and a yarn guide nozzle structure 3 located at the top of the B base 21. A quick installation structure 4 is provided in the middle of the A base 2 and the B base 21;

[0020] The yarn guide nozzle structure 3 includes a limiting groove 31 opened at the top of the B base 21 and a guide rod 32 inserted into the inner wall of the limiting groove 31, and threaded sleeves 33 fixedly installed on the front and back of the B base 21. A threaded rod 34 is rotatably connected to the inner wall of the threaded sleeve 33. One end of the threaded rod 34 close to the B base 21 is rotatably connected to an abutting block 35 through a bearing, and a yarn guide nozzle 36 is fixedly installed at the top of the guide rod 32.

[0021] Adopting the above scheme: Through the design of the yarn guide nozzle 36 structure 3 and the quick installation structure 4, the A base 2 and the B base 21 are plugged together to form a complete base. When the base needs to be replaced, only the A base 2 and the B base 21 need to be sleeved on the outer wall of the yarn guide rod 51, and the positioning is achieved by inserting the plugging block 42 into the inner wall of the installation groove 41. Subsequently, the A base 2 and the B base 21 are locked by using the screw 44 and the nut 45, achieving the effect of quick replacement. This method not only greatly reduces the time required for replacing the base, improves production efficiency, but also reduces maintenance costs. Secondly, if the yarn guide nozzle 36 is damaged individually, the threaded rod 34 can be rotated to drive the abutting block 35 to move. The movement of the abutting block 35 pushes the guide rod 32, so that the connection relationship between the guide rod 32 and the through groove and the limiting groove 31 is released. In this way, the yarn guide nozzle can be directly taken out for replacement without disassembling the entire yarn guide device. When replacing the new yarn guide nozzle 36 subsequently, only need to bend the two guide rods 32 towards the middle so that they can be inserted into the inner wall of the limiting groove 31. When inserted into the inner wall of the limiting groove 31, the guide rod 32 rebounds with its own rigidity and is clamped and fixed with the through groove and the limiting groove 31, thus achieving the effect of quickly installing the yarn guide nozzle 36. This design not only facilitates the operation and maintenance of the operator, but also ensures the stability and reliability of the yarn guide nozzle after installation.

[0022] As Figures 1 to 5 shown, the quick installation structure 4 includes an installation groove 41 opened at the surface where the B base 21 and the A base 2 are in contact with each other, and a plugging block 42 inserted into the inner wall of the installation groove 41 and fixedly connected to the A base 2. Installation blocks 43 are provided on the surfaces where the A base 2 and the B base 21 are in contact with each other, and installation holes are opened in the inner walls of the installation blocks 43.

[0023] Adopting the above scheme: the accurate positioning between the plug-in block 42 and the mounting groove 41 plays a vital role in the yarn guide device of the rotor spinning machine, and can achieve the precise installation effect between the A base 2 and the B base 21. In actual operation, the process is simple and efficient. It only needs to accurately plug the plug-in block 42 carefully arranged on the outside of the A base 2 into the mounting groove 41 opened on the inner wall of the B base 21, so as to quickly achieve the positioning between the A base 2 and the B base 21. The design of the plug-in block 42 and the mounting groove 41 also takes into account the adaptability under different working conditions. Whether in a high-speed spinning environment or in the case of frequent replacement of the base, this positioning method can function reliably. It can withstand a certain degree of wear and impact, and can still maintain good positioning accuracy after long-term use, providing a strong guarantee for the stable operation of the yarn guide device.

[0024] like Figures 1 to 5 As shown, the inner wall of the mounting hole is rotatably connected to a screw rod 44 , the outer wall of the screw rod 44 is threadedly connected to a nut 45 , a through groove connected to the threaded sleeve 33 is provided on the inner wall of the limiting groove 31 , and the abutment block 35 is in contact with the guide rod 32 .

[0025] The above solution is adopted: the guide rod 32 has a certain elasticity, so that when installing, it can be driven to move toward the middle by bending the two guide rods 32, and then the guide rod 32 is released, and it is fixed by rebounding and clamping between the through groove and the installation groove 41.

[0026] The working principle and use process of this utility model:

[0027] When the base 36 is replaced, the two guide rods 32 are bent toward the middle to insert them into the inner wall of the limit groove 31. With their own rigid rebound, the guide rod 32 is clamped and fixed to the through groove and the limit groove 31 to achieve quick installation. This design facilitates maintenance and replacement by operators, while ensuring the stability and reliability of the yarn guide nozzle after installation, thereby improving the availability and production efficiency of the equipment.
