Description

Technical Field

[0001] The utility model relates to the technical field of rotor spinning, in particular to a damping mechanism for a rotor spinning machine. Background Art

[0002] Rotor spinning is a form of open-end spinning, so-called because it uses a rotor to condense single fibers. Initially, it primarily used airflow, also known in China as air spinning. Rotor spinning offers high spinning speeds, large winding capacity, and excellent suitability for spinning low-grade cotton and waste noil, while significantly improving the working environment. During operation, the rotor of a rotor spinning machine rotates at high speed while simultaneously winding the yarn. During deceleration and stopping, a damping mechanism is required to buffer and brake the machine. With technological advancements, the variety of damping mechanisms used in rotor spinning machines has steadily increased.

[0003] However, the existing damping mechanism has an insignificant buffering effect during use. When braking a rotating structural member such as a rotor, the braking noise is relatively loud due to the low buffering performance, and excessive damping pressure can easily cause damage to the rotor structure or structural members on the damping mechanism. Excessive buffering effect can easily result in an insignificant damping effect and a decrease in speed reduction performance. Therefore, this design proposes a damping mechanism for a rotor spinning machine. Utility Model Content

[0021] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0022] The examples are as follows:

[0023] The utility model provides Figure 1-5 The damping mechanism shown is used for a rotor spinning machine, comprising a damping base 1 and damping brake mechanisms 2 installed at both ends of the damping base 1;

[0024] The damping brake mechanism 2 includes support plates 201 installed at both ends of the damping base 1, one side of the two support plates 201 is fixed with a mounting bracket 202, one side of the two mounting brackets 202 is interspersed with a support shaft 203, one end of the two support shafts 203 is fixed with a gasket 204, one side of the two gaskets 204 is fixed with a friction plate 205, the outer wall of one end of the two support shafts 203 is sleeved with a first spring 206, and the two ends of the two first springs 206 are respectively fixedly connected to one side of the two mounting brackets 202 and the other side of the two gaskets 204, one end of the inner wall of the two mounting brackets 202 is installed with a support bracket 207, and the two mounting brackets 207 are fixed with a support bracket 207. A limit frame 208 is fixed to the other end of the inner wall of the mounting frame 202. When the rotor spinning machine is running and the rotor needs to slow down or stop by braking, the connecting shaft 8 is pushed by the small cylinder 7, thereby pushing the support plate 201 with the friction plate 205 to contact the rotor for friction braking. During friction, the friction plate 205 is squeezed and the first spring 206 is compressed, thereby causing the support shaft 203 to penetrate the mounting frame 202. During penetration, the support shaft 203 always slides on the inner wall of the support frame 207, so that it remains stable, which is convenient for later insertion into the interior of the limit frame 208. At the same time, it can also ensure the stability of the friction plate 205 and the gasket 204 when rubbing the rotor.

[0025] Furthermore, the outer walls of the other ends of the two support shafts 203 are respectively connected to the inner walls of the two support frames 207 and the two limiting frames 208, and connecting holes 209 are provided on both sides of the inner walls of the two limiting frames 208.

[0026] The inner walls of the two connecting holes 209 are interspersed with limiting balls 210, and one side of the inner walls of the two connecting holes 209 is fixedly provided with a second spring 211, and one end of the two second springs 211 is fixedly connected to one side of the two limiting balls 210 respectively. One end of the two support shafts 203 has a round head, which does not encounter much resistance when inserted into the limiting frame 208 and squeezed by the two limiting balls 210, and is stuck in the connecting hole 209, so that the round head end of the support shaft 203 continues to pass through until the limiting balls 210 no longer shrink, and its outer wall contacts the outer walls on both sides of the support shaft 203 and squeezes and locks it. The position of the master friction plate 205 is fixed and contacts the outer wall of the rotor cup, so that the rotor cup is braked by its friction after deceleration;

[0027] Furthermore, an annular limiting groove 3 is provided at the lower end of the inner wall of the damping base 1, and limiting sliding grooves 4 are provided on both sides of the inner wall of the damping base 1, and the outer walls of the two support plates 201 and the outer walls of the two mounting frames 202 are respectively slidably connected to the inner walls of the two limiting sliding grooves 4, and the support plates 201 and the mounting frames 202 are inserted into the limiting sliding grooves 4 to ensure the overall stability of the damping brake mechanism 2;

[0028] Furthermore, a fixed bracket 5 is fixed at the lower edge of the outer wall of the damping base 1, and connecting plates 6 are fixed on both sides of the fixed bracket 5. Small cylinders 7 are installed on one side of the two connecting plates 6. The output ends of the two small cylinders 7 are interspersed with connecting shafts 8 through the inner walls of the two connecting plates 6, and when the small cylinder 7 drives the connecting shaft 8 to extend and retract, the connecting shaft 8 passes through the limiting slide groove 4 and pushes the support plate 201 to move therein.

[0029] One end of the two connecting shafts 8 is fixedly connected to the other side of the two support plates 201 respectively. Mounting holes 9 are provided on both sides of the top of the fixing bracket 5. The entire damping mechanism can be installed and fixed through the mounting holes 9 on the fixing bracket 5.

[0030] Working principle: When using the damping mechanism for the rotor spinning machine in this design, the rotor is first supported by the damping base 1 and the annular limit groove 3 on the inner wall, and the rotor can rotate in the annular limit groove 3, so that it is limited and not easy to fall out. During the damping process, the small cylinder 7 on the connecting plate 6 is started to extend the connecting shaft 8 therein to push the support plate 201 and then carry the mounting frame 202 to slide in the limit slide groove 4. During the sliding process, it moves with the gasket 204 and the friction plate 205 until it contacts both sides of the rotating end of the rotor and continues to push the support plate 201 through the connecting shaft 8 so that the friction plate 205 is continuously squeezed on the outer wall of the rotor to brake it. During this process, the mounting frame 202 continuously compresses the first spring 206 and makes the support shaft 203 penetrate in the support frame 207, so that it keeps moving in the center and is stuck in the limit frame 208. This process is a buffering process. The second spring 211 is compressed and received by the support shaft 203, and the second spring 211 is compressed and received by the support shaft 203, and the support shaft 203 is stuck and cannot move further. The friction plate 205 cannot be retracted, and then rubs the outer wall of the rotor cup until it stops rotating. In this process, the damping brake mechanism 2 first contacts the rotor cup and continuously buffers the outer wall of the rotor cup through the elasticity of the first spring 206 during friction. When the speed of the rotor cup is reduced and the support shaft 203 is stuck and cannot move due to the limit ball 210 in the connecting hole 209, the friction plate 205 is no longer buffered by the first spring 206, and the rotor cup after deceleration is completely stopped, that is, it plays the role of a buffering and protective structural member, and can effectively decelerate and brake the rotor cup, thereby improving the damping quality of the device.
