Technical Field

[0001] The present disclosure relates to the technical field of textile equipment, and particularly to a circular knitting machine encoder seat. Background Art

[0002] A circular knitting machine encoder seat is mainly designed to install and fix an encoder to ensure that the encoder can accurately and stably measure the rotational motion of the circular knitting machine. In the existing design of the circular knitting machine encoder seat, due to the lack of effective sealing and isolation measures between the transmission shaft and the encoder, oil leakage from the transmission shaft, dust, or other impurities often enter the interior of the encoder, resulting in a decline in the performance of the encoder, frequent failures, and even affecting the operation stability and product quality of the entire circular knitting machine. Therefore, an encoder seat structure for a circular knitting machine that can effectively prevent oil leakage from the transmission shaft is needed. Summary of the Utility Model

One end of the transmission shaft is installed on the base through the installation hole and extends to the outside of the base to be in transmission connection with the encoder through a coupling, and the other end is installed with the synchronous pulley. The isolation component is arranged between the base and the synchronous pulley;

[0006] A convex portion is provided above the base, and the isolation component is located on the convex portion. Through the isolation component, an isolation barrier is formed between the base and the synchronous pulley;

[0029] Refer to Figures 1-4 , a large circular knitting machine encoder seat, comprising a base 1, an isolation component 2, a synchronous pulley 3 for connecting with a large disc gear, and a transmission shaft 4 for linking the encoder. An installation hole 11 is provided in the base 1. One end of the transmission shaft 4 is installed on the base 1 through the installation hole 11 and extends to the outside of the base 1 to be in transmission connection with the encoder through a coupling, and the other end is installed with the synchronous pulley 3. The isolation component 2 is arranged between the base 1 and the synchronous pulley 3;

[0030] Above the base 1, there is a convex part 12. The isolation component 2 is located on the convex part 12. Through the isolation component 2, a separation barrier is formed between the base 1 and the synchronous pulley 3, so that a sealed cavity is formed between the base 1, the isolation component 2 and the synchronous pulley 3 and the transmission shaft 4, thereby isolating and blocking impurities such as oil and dust infiltrated by the transmission shaft 4, and improving the service life and working stability of the encoder;

[0031] The isolation component 2 includes a sealing ring 21 and a sealing cover 22. The sealing cover 22 is fixedly installed on the convex part 12. The transmission shaft 4 is located inside the sealing cover 22. A fitting port 221 is provided at the bottom of the sealing cover 22. The sealing cover 22 is snap-connected to the fitting port 221 through the convex part 12 to form a first sealing barrier, thereby protecting the transmission shaft 4 installed on the base 1, reducing the situation of oil, dust or other impurities infiltrating into the transmission shaft 4 and entering the encoder, and reducing the probability of the encoder being damaged. The sealing ring 21 is located inside the sealing cover 22. The sealing ring 21 is made of a sealing material compatible with oil and wear-resistant to improve the sealing performance and durability of the sealing ring 21. The sealing ring 21 fits against the inner wall of the sealing cover 22. When the transmission shaft 4 is located inside the sealing cover 22, the outer circumference of the transmission shaft 4 fits against the inner wall of the sealing ring 21, enabling the sealing ring 21 to wrap the transmission shaft 4 and form a second sealing barrier for further isolating and blocking impurities such as oil and dust infiltrated by the transmission shaft 4, and improving the service life and working stability of the encoder;

[0032] The top of the sealing cover 22 has an annular convex part 222, and a groove 31 is provided at the bottom of the synchronous pulley 3. By embedding the annular convex part 222 into the groove 31, the synchronous pulley 3 is installed on the sealing cover 22 to form a third sealing barrier, effectively preventing impurities such as oil and dust infiltrated by the transmission shaft 4 from entering the encoder, and improving the service life and working stability of the encoder.

[0033] Based on the above structure, due to the structural setting of the sealing cover 22 in the isolation component 2, when the sealing cover 22 is fixedly installed on the convex part 12 of the base 1 and the transmission shaft 4 is located inside the sealing cover 22, the sealing cover 22 is snap-connected to the fitting port 221 through the convex part 12 to form a first sealing barrier, thereby protecting the transmission shaft 4 installed on the base 1, reducing the situation of oil, dust or other impurities infiltrating into the transmission shaft 4 and entering the encoder, and reducing the probability of the encoder being damaged. Also, due to the structural setting of the sealing ring 21 installed inside the sealing cover 22, when the transmission shaft 4 is located inside the sealing cover 22, the outer circumference of the transmission shaft 4 fits against the inner wall of the sealing ring 21, enabling the sealing ring 21 to wrap the transmission shaft 4 and form a second sealing barrier for further isolating and blocking oil, dust or other impurities infiltrated by the transmission shaft 4, achieving effective sealing and isolation between the transmission shaft 4 and the encoder, and at the same time improving the service life and working stability of the encoder;

[0034] Furthermore, since the top of the sealing cover 22 has an annular protrusion 222 and the bottom of the synchronous pulley 3 is provided with a groove 31, by embedding the annular protrusion 222 into the groove 31, the synchronous pulley 3 is mounted on the sealing cover 22 to form a third sealing barrier. Through the multiple sealing and isolation design of the isolation component 2, it can effectively prevent impurities such as oil and dust from infiltrating into the encoder through the transmission shaft 4, improving the stability and reliability of the encoder, correspondingly enhancing the overall operating efficiency of the circular knitting machine, and at the same time reducing the downtime and maintenance costs caused by encoder failures.

[0035] In one implementation, referring to Figures 1-4 , when the sealing cover 22 is mounted on the protrusion 12, the inner surface of the sealing cover 22 fits with the outer surface of the protrusion 12, and the sealing cover 22 is movably connected to the base 1. This enables quick and convenient disassembly and replacement when the sealing cover 22 is damaged, and at the same time facilitates the replacement of the sealing ring 21 installed in the sealing cover 22, improving the installation convenience of the isolation component 2;

[0036] When the synchronous pulley 3 is mounted on the sealing cover 22, the inner surface of the groove 31 fits with the outer surface of the annular protrusion 222, and the synchronous pulley 3 is movably connected to the sealing cover 22. This enables quick and convenient disassembly and replacement when the isolation component 2 is damaged, simplifies the maintenance process, reduces downtime, and improves the maintenance efficiency, thereby enhancing the practicality and working efficiency of the encoder seat.

[0037] In one implementation, referring to Figure 1 and Figure 3 , a bearing 13 is provided between the transmission shaft 4 and the base 1, and a hole card 14 is further provided at the bottom of the base 1. There are two bearings 13, and the base 1 is disposed between the two bearings 13. The setting of the bearing 13 enables the transmission shaft 4 to maintain a stable operating state on the base 1, while reducing friction, effectively extending the service life of the transmission shaft 4, and reducing mechanical failures and downtime caused by wear. The outer side of the bearing 13 at the bottom of the base 1 is positioned by the hole card 14. By positioning with the hole card 14, it can ensure that the bearing 13 maintains a stable position during use, thereby reducing errors caused by the movement or deviation of the bearing 13, and enhancing the stability of the transmission shaft 4 during use.
