Description

Technical Field

[0001] The utility model relates to the technical field of air-jet spinning machines, in particular to a new type of spinning cup for air-jet spinning machines. Background Art

[0002] Air-jet spinning is a new type of spinning technology that uses airflow to condense and twist fibers in a high-speed rotating spinning cup and output them into yarn. It does not use spindles, but mainly relies on multiple components such as combing rollers, spinning cups, and false twist devices. The combing roller is used to grab and comb the fed cotton sliver fibers, and the centrifugal force generated by its high-speed rotation can throw the grabbed fibers out. The spinning cup is a small metal cup, and its rotation speed is more than 10 times higher than that of the combing roller. The resulting centrifugal effect discharges the air in the cup outward; according to the principle of fluid pressure, the cotton fibers enter the airflow cup and form a fiber flow that moves continuously along the inner wall of the cup.

[0003] In the process of air-jet spinning, the use of spinning rotors is indispensable. During the installation process, existing spinning rotors are often installed through threads. However, since the machine will generate certain vibrations during operation, after a long period of operation, the spinning rotor thread installation may become loose, which will affect the production quality and even cause the spinning rotor to fall, thus affecting production efficiency.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Embodiment 1:

[0020] Please refer to Figure 1-4 A new type of spinning rotor for an air-jet spinning machine comprises a spinning rotor body 1, a mounting threaded barrel 2 is fixedly mounted on the lower surface of the spinning rotor body 1, a mounting plate 3 is fixedly mounted on the outer surface of the mounting threaded barrel 2, a limiting hole 4 is arranged on the surface of the mounting plate 3, a wire outlet base 5 is threadedly mounted on the inner wall of the mounting threaded barrel 2, a pipe sleeve 6 is fixedly mounted on the upper surface of the wire outlet base 5, a pipe column 7 is movably mounted on the inner wall of the pipe sleeve 6, a torsion spring 8 is fixedly mounted on the lower end of the pipe column 7, a connecting rod 9 is fixedly mounted on the upper end of the pipe column 7, a limiting block 10 is fixedly mounted on the upper end of the connecting rod 9, and a mounting block 11 is fixedly mounted on the outer surface of the wire outlet base 5.

[0021] Specifically: during the use of the utility model, when the spinning cup needs to be installed, the spinning cup body 1 is manually threadedly installed through the threaded barrel 2 and the mounting block 11. After the threaded installation is completed, the limit block 10 will be directly below the limit hole 4. At this time, the pipe column 7 is manually rotated, and the pipe column 7 rotates, thereby driving the connecting rod 9 and the limit block 10 to rotate, until the limit block 10 is rotated to match the limit hole 4, the torsion spring 8 is in a twisted state at this time, and then the limit block 10 is directly inserted and installed through the limit hole 4, until the limit block 10 is completely inserted through the limit hole 4, the pipe column 7 is released at this time, due to the resilience of the torsion spring 8, the limit block 10 is driven to reset, until the limit block 10 is reset, the torsion spring 8 will also drive the limit block 10 to move downward, so that the silicone plate is attached to the upper surface of the mounting plate 3 to complete the limit.

[0022] In this embodiment: a silicone pad 15 is fixedly installed on the lower surface of the limit block 10, the size of the limit hole 4 matches the size of the limit block 10, the limit hole 4 is an oblique cross shape, and the lower end of the torsion spring 8 is fixedly connected to the lower inner wall of the pipe sleeve 6.

[0023] Specifically: when the limit block 10 is in the restricted state, it does not match the position of the limit hole 4. The design of the silicone pad 15 can increase the friction between the limit block 10 and the mounting plate 3 on the one hand, making it difficult for the limit block 10 to move. On the other hand, it can play a buffering role to protect the limit block 10.

[0024] In this embodiment: the surface of the mounting block 11 is provided with threads, and the outer surface of the threads is threadedly connected to the inner wall of the mounting thread barrel 2 .

[0025] Specifically, the installation of the spinning rotor body 1 and the wire outlet base 5 is achieved through the installation block 11 and the installation thread barrel 2.

[0026] Working principle: In the utility model, when the spinning cup body 1 needs to be installed, the spinning cup body 1 and the wire outlet base 5 are first installed by installing the threaded barrel 2 and the mounting block 11. After the installation is completed, the limiting block 10 is used again to cooperate with the limiting hole 4 and the torsion spring 8 to complete the limiting of the wire outlet base 5. Compared with the related art, the new spinning cup of the air-jet spinning machine provided by the utility model has the following beneficial effects: the design can achieve the effect of auxiliary installation of the spinning cup body 1 and the wire outlet base 5, thereby avoiding the situation in which the thread of the machine becomes loose after a long period of vibration operation, resulting in a decrease in production quality and the spinning cup falling off, thereby affecting production efficiency.

[0027] Embodiment 2:

[0028] Please refer to Figure 1-4 A wire hole 12 is provided on the upper surface of the wire outlet base 5 , a brush head 13 is fixedly installed on the upper side of the inner wall of the wire hole 12 , and an air supply pipe 14 is fixedly installed on the upper surface of the spinning cup body 1 .

[0029] Specifically: when the spinning rotor is working, the yarn will pass through the yarn hole 12 and be transported to the next link. When the yarn reaches the yarn hole 12 after being combed by the spinning rotor, the brush head 13 will clean the yarn surface, thereby cleaning the fluff adhering to the yarn surface. At this time, the air supply pipe 14 is externally connected to a suction fan to suck away the fluff for cleaning, and finally it is cleaned uniformly manually.

[0030] In this embodiment, the interior of the air delivery pipe 14 and the interior of the spinning rotor body 1 are interconnected, and the air delivery pipe 14 can be externally connected to a suction fan.

[0031] Specifically, the air delivery pipe 14 is externally connected to a suction fan so as to suck out the fluff in the spinning rotor body 1, and then the fluff is processed uniformly by humans.

[0032] Working principle: The utility model cleans the lint adhered to the surface of the spinning thread through the brush head 13, and then cleans the lint through the air duct 14. Compared with the related art, the utility model provides a new spinning cup for an air-jet spinning machine with the following beneficial effects: the design can improve the production quality of the spinning thread while cleaning the lint inside the spinning cup, thereby avoiding the accumulation of lint inside the spinning cup, causing problems with the spinning thread flow, and thus affecting production efficiency.

[0033] The above-mentioned equipment is used in different ways for each device. It is selected and used according to actual conditions, and various parameters are referred to, in accordance with the functions of the equipment used and the effects achieved.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
