[0033] Specifically, the shape and size of the inner cross-section of the clamping sleeve 85 are the same as those of the outer cross-section of the clamping rod 84.

[0034] By adopting the above technical solution, the structure can ensure that the inner side of the clamping sleeve 85 is in close contact with the outer side of the clamping rod 84, thereby reducing the possibility of unstable installation and better meeting the working requirements.

[0035] When this embodiment is in use, when it is necessary to disassemble structures such as the spinning cup body assembly 6, pull the pull plate 83 in the installation and connection device 8, thereby overcoming the force of the tension spring 82 to drive the clamping rod 84 to disengage from the clamping sleeve 85 on the installation block 1, and then pull out structures such as the spinning cup body assembly 6. After disassembly, the fixed sleeve 81 is a structure fixed on the air-jet spinning machine. When it is necessary to install structures such as the spinning cup body assembly 6, pull the pull plate 83, thereby overcoming the force of the tension spring 82 to drive the clamping rod 84 to descend to a height that does not affect the normal entry of the installation block 1, and then send the installation block 1 and its upper structures into the fixed sleeve 81. Release the pull plate 83, and under the action of the tension spring 82, the pull plate 83 rises, thereby driving the clamping rod 84 to insert into the clamping sleeve 85, and the installation is completed.

[0036] The structure and principle of the rotating cup shaft 2, the shaft sleeve 3, the damping component 4 composed of a protective sleeve, a damping rod, a damping cylinder, a spring, a through hole and a buffer pad, the yarn guide tube 5, and the spinning cup body component 6 composed of a spinning cup body, a cotton condensing groove, a through hole and a groove in the utility model have been disclosed in a spinning cup device for a textile machinery disclosed in Chinese patent application No. 201820060363.8. Its working principle is to set the groove so that the fiber entering the spinning cup body is immersed in the groove, and an air flow is formed in the high-speed rotating spinning cup body, which is conducive to the rapid movement of the fiber in the groove, the condensing groove, the merging, and the twisting into yarn. The dust and other impurities mixed in the fiber are subjected to a centrifugal force greater than the fiber in the high-speed rotating spinning cup body, which is conducive to the impurities It sinks to the bottom of the groove and moves toward the cotton condensing groove, and is discharged through the through holes arranged on the cotton condensing groove, which is beneficial to the discharge of impurities in the fiber and increases the product quality; the two lateral sides of the groove are inclined, which is beneficial to the inflow of fibers and evacuates the fibers in the groove to prevent fiber accumulation and accelerate the molding of the product; further, the buffer device arranged between the shaft sleeve and the frame is beneficial to reduce the vibration of the spinning cup body, increase the stability of the spinning cup body, and improve the service life. A spring is arranged in the shock-absorbing cylinder to absorb the vibration on the spinning cup body. The through holes arranged at the lower part of the shock-absorbing cylinder prevent the spinning cup body from moving too much and increase the stability of the spinning cup body; the buffer pad arranged on the end edge of the shock-absorbing cylinder prevents excessive vibration and damage caused by collision between the shock-absorbing cylinder and the protective cover.

[0037] Working principle and usage process of the present utility model: When the air-jet spinning machine needs to use the spinning cup structure, fibers pass through the rotor shaft 2 and the yarn guide tube 5 and enter the spinning cup body assembly 6. Then, through the spinning cup body assembly 6, the fibers are condensed, combined, and twisted into yarn. The staff can start the electric telescopic rod 72 on the fixed plate 71 in the winding and drying device 7, thereby driving the lifting plate 73, the connection box 74 and other structures to move until the winding roller 77 moves to one side of the spinning cup body assembly 6. The staff can connect the yarn to the winding roller 77 and then start the motor 76. The motor 76 drives the winding roller 77 to rotate, thereby winding the yarn and then using it. When necessary, the staff can start the fan 752 and each heating rod 753 in the drying assembly 75. The fan 752 sends air into the connecting cylinder 751, and then each heating rod 753 heats the air. Then the hot air enters the connection box 74, and then dries the yarn. The shock-absorbing assembly 4 on the shaft sleeve 3 can buffer the vibration; When it is necessary to disassemble the spinning cup body assembly 6 and other structures, pull the pull plate 83 in the installation and connection device 8, thereby overcoming the force of the tension spring 82 to drive the clamping rod 84 to disengage from the clamping sleeve 85 on the mounting block 1, and then pull out the spinning cup body assembly 6 and other structures. After the disassembly is completed, the fixed sleeve 81 is a structure fixed on the air-jet spinning machine. When it is necessary to install the spinning cup body assembly 6 and other structures, pull the pull plate 83, thereby overcoming the force of the tension spring 82 to drive the clamping rod 84 to descend to a height that does not affect the normal entry of the mounting block 1. Then send the mounting block 1 and its upper structures into the fixed sleeve 81, release the pull plate 83, and under the action of the tension spring 82, the pull plate 83 rises, thereby driving the clamping rod 84 to insert into the clamping sleeve 85. After the installation is completed.
