Description

Technical Field

[0001] This utility model relates to the field of spinning equipment technology, specifically to a handle sealing structure for a rotor spinning chamber. Background Technology

[0002] The rotor spinning machine consists of multiple identical units arranged adjacent to each other on both sides of the frame. Its process negative pressure and impurity removal negative pressure are generated by process fans and impurity removal fans located at the rear of the machine. These negative pressures are transmitted through PVC pipes throughout the entire machine body. To facilitate the cleaning of short fibers and impurities generated during spinning, an air chamber is provided between the fans and the PVC pipes. Cleaning the air chamber of short fibers and impurities requires changing the air duct, hence the inclusion of a handle.

[0003] In existing technologies, such as Figure 1 and Figure 2 As shown, the same-function device used on rotor spinning machines has the following problems: the handle is made of flat iron, requiring a large opening in the air chamber wall panel; the seal at the handle opening relies on the rubber gasket between the air chamber wall panel and the handle, which places high demands on the flatness of the wall panel and assembly; even slight wear of the mechanism can cause poor sealing and poor fault tolerance. All of these problems will increase energy consumption. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] like Figure 1 and Figure 2 The image shows the existing structure for the rotor spinning chamber handle installation. The existing handle has the following problems:

[0023] 1. The handles used are made of flat iron, and the holes in the ventilation chamber wall panel need to be relatively large;

[0024] 2. The sealing at the handle opening relies on the rubber gasket between the air chamber wall panel and the handle, which requires a high degree of flatness of the wall panel and proper assembly.

[0025] 3. Even slight wear and tear on the mechanism can lead to poor sealing and reduced fault tolerance. These problems all contribute to increased energy consumption.

[0026] Please see Figures 3-5 This utility model provides a technical solution: a handle sealing structure for a rotor spinning air chamber, comprising: an installation sleeve 3 fixedly installed on the air chamber wall panel 1 and a linkage plate 6 movably installed on the air damper. A sealing ring 4 is fixedly installed inside the installation sleeve 3, and a pull rod 2 is inserted inside the sealing ring 4. The pull rod 2 reciprocates within the sealing ring 4 to switch the air damper. A small hole is opened in the air chamber wall panel 1 for fixing the installation sleeve 3, and the sealing ring 4 is fixedly installed on the inner end of the installation sleeve 3. The pull rod 2 passes through the sealing ring 4, and the outer wall of the pull rod 2 and the inner wall of the sealing ring 4 slide in contact. The sealing ring 4 seals the connection between the pull rod 2 and the installation sleeve 3. The structure is compact, has low requirements for assembly precision, and can effectively seal, reduce energy consumption, and reduce maintenance time.

[0027] One end of the pull rod 2 is inserted into the air chamber and fixedly connected to one end of the linkage plate 6 through the connecting component. The other end of the pull rod 2 is located on the outside of the air chamber wall panel 1 and is fixedly connected to the handle 5. A rectangular frame is fixedly installed on one side of the handle 5 by bolts. The end of the rectangular frame away from the handle 5 is fixedly connected to the end of the pull rod 2 away from the linkage plate 6. By holding the handle 5, the pull rod 2 can be driven to move back and forth in the air chamber. When the pull rod 2 moves, it moves the linkage plate 6 at the same time, thereby switching the damper. The outer end of the air chamber wall panel 1 is provided with a groove corresponding to the rectangular frame. When the handle 5 is close to the air chamber wall panel 1, the rectangular frame is located in the groove.

[0028] The connecting component includes two parallel connecting blocks 7. One end of the two connecting blocks 7 is fixed to the outer side of one end of the linkage plate 6 by bolts. The other end of the two connecting blocks 7 is fixed to a fixing block 8 by bolts. Both connecting blocks 7 have operating holes 9 on their side walls. The end of the pull rod 2 away from the handle 5 has a threaded groove 10. The end of the pull rod 2 away from the handle 5 passes through the side wall of the fixing block 8 and is threaded with two adjusting nuts 11. The two adjusting nuts 11 are located on the inner and outer sides of the fixing block 8, respectively. The adjusting nuts 11 at the inner end of the fixing block 8 can be adjusted through the operating holes 9, which facilitates the disassembly and assembly of the pull rod 2.

[0029] In actual use, a small hole is made in the wall panel 1 of the air chamber for fixing the mounting sleeve 3, and a sealing ring 4 is fixedly installed on the inner end of the mounting sleeve 3. The pull rod 2 passes through the sealing ring 4 and is fixedly connected to the linkage plate 6 through the connecting component. The outer end of the pull rod 2 is fixedly connected to the handle 5. The pull rod 2 can be driven to move back and forth through the handle 5. When the pull rod 2 moves, the outer wall and the inner wall of the sealing ring 4 slide into contact. The sealing ring 4 seals the connection between the pull rod 2 and the mounting sleeve 3. The pull rod 2 synchronously drives the linkage plate 6 to move back and forth to switch the damper. This device has a compact structure, low requirements for assembly precision, and can effectively seal, reduce energy consumption, and reduce maintenance time.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
