Its main function is to apply sizing agent to the yarn to enhance its wear resistance and tensile resistance, ensuring the smooth progress of subsequent weaving processes. The stable operation of the sizing machine highly depends on the reliability of the power transmission system. The connecting structure between the motor drive shaft and the main shaft of the sizing machine is the core link of power transmission, and its performance directly affects the running stability of the sizing machine, the quality of the yarn and the production efficiency.
[0003] The shaft connecting structure used in the sizing machine on the market is mostly rigid connection, such as directly rigidly fixing the motor drive shaft and the main shaft of the sizing machine through a shaft coupling.

[0019] REFERENCE Figures 1-4 The application provides a shaft connecting structure, which comprises: the core function of the shaft connecting structure is to realize the synchronous rotation of the driving shaft of a motor and the main shaft of a sizing device, and the whole is composed of three parts: a first shaft body 1 connected with the driving shaft of the motor, a second shaft body 2 connected with the main shaft of the sizing device, and a connecting mechanism connecting the two. It is worth noting that the axes of the first shaft body 1 and the second shaft body 2 coincide, which lays the foundation for the smooth transmission of power, and the connecting mechanism is the key to ensuring the synchronous rotation of the two.
[0020] The connecting mechanism realizes efficient transmission of power through the matching of the protrusions and the mounting areas. At the end of the first shaft body 1, two first protrusions 11 are arranged symmetrically with the axis of the first shaft body 1 as the axis of symmetry, and two first mounting areas 12 are naturally formed between the two protrusions. Correspondingly, the end of the second shaft body 2 is also provided with two second protrusions 21, which are symmetrically distributed with the axis of the second shaft body 2 as the axis of symmetry, and two second mounting areas 22 are formed between the protrusions.
[0021] When the first shaft body 1 is connected with the second shaft body 2, the two second protrusions 21 can be correspondingly clamped in the two first mounting areas 12, and the two first protrusions 11 can also be clamped in the two second mounting areas 22. This interlocking clamping method not only ensures the stability of power transmission, but also ensures the synchronization of the two shafts during rotation, avoiding power loss due to loose connection.
[0022] To further improve the practicality and durability of the structure, multiple optimizations are made in the detail design of the shaft connecting structure. In the gap design, a first gap 13 is left between the first protrusion 11 and the second shaft body 2, and a second gap 23 is provided between the second protrusion 21 and the first shaft body 1, and the thickness of the two gaps is consistent. This design not only provides space for thermal expansion and contraction of the components, but also avoids rigid collision during operation, effectively reducing friction and wear.
[0023] In the fixing method, the first shaft body 1 is provided with a first screw hole 14 along the radial direction, and the first shaft body 1 can be firmly connected with the driving shaft of the motor by installing a first bolt; the second shaft body 2 is also provided with a second screw hole 24 along the radial direction, and the second shaft body 2 is fixed with the main shaft of the sizing device by means of a second bolt. This bolt fixing method not only has the advantages of convenient installation, but also can ensure the stability of the connection and prevent the shaft body from moving during high-speed operation.
[0024] Especially important is that the first shaft body 1 and the second shaft body 2 are designed with non-rigid connection, leaving a certain amount of allowance. This design effectively avoids the wear of components caused by vibration or slight deviation in traditional rigid connection, and fundamentally reduces the generation of pollution sources, providing a strong guarantee for the cleanliness of the sizing process.
[0025] The shaft connecting structure has shown significant advantages in practical application. First, by reducing wear and tear and the generation of pollution sources, the probability of contaminated yarn is greatly reduced. After multiple production tests and verifications, the equipment using this structure has a significant decrease in the occurrence rate of contaminated yarn compared to traditional structures, fundamentally improving the product quality of the yarn.
[0026] Secondly, the enhancement of equipment operation stability directly leads to the improvement of production efficiency. Due to the reduction of downtime maintenance time caused by wear and tear and failure, the equipment can maintain continuous and stable operation, shortening the production cycle. In the continuous production process, the running state of the equipment is more reliable, not only reducing the production cost, but also creating higher economic benefits for the enterprise.
[0027] In summary, this new type of shaft connection structure applied to the sizing machine, through the innovative design concept and precise detail control, effectively solves the wear and tear and pollution problems of the traditional structure while ensuring efficient power transmission, providing strong support for high-quality production of the textile industry, and can be called an important technical breakthrough for upgrading the sizing machine equipment.
[0028] The above describes only the preferred specific embodiments of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art within the technical range disclosed by the present application, according to the technical solution of the present application and the concept of the present application, equivalent replacement or change, should be covered within the protection scope of the present application.
