Description

Technical Field

[0001] This invention relates to the field of rotor spinning machine technology, and more specifically, to an automatic rotor cleaning mechanism and cleaning method. Background Technology

[0002] Rotor spinning machines are devices that operate continuously 24 hours a day, and the opening and closing locking structure of the spinner serves the entire life cycle of the equipment. Currently, before yarn splicing, the spinner needs to be manually opened to remove remaining fibers from the rotor. When dust accumulates in the condensation tank, it also needs to be cleaned with a brush or air gun, resulting in a significant workload. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic rotating cup cleaning mechanism and cleaning method.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This invention discloses an automatic rotor cleaning mechanism, including a spinning machine housing assembly and a rotor seat assembly, which are rotatably connected. The rotor seat assembly includes a rotor head, a vortex cavity, and a process air duct. The rotor head is located in the middle of the rotor seat assembly. The process air duct is sealed to the rotor seat assembly, and one end of the process air duct is connected to the vortex cavity. A yarn guide seat and a flexible channel are installed on the spinning machine housing assembly. A false twist disc is installed in the middle of the flexible channel. One end of the yarn guide seat is connected to the false twist disc, and the other end of the yarn guide seat is connected to an untwisting component.

[0006] Furthermore, the untwisting assembly includes an untwisting seat, a yarn guide seat, and a sealing sleeve between the untwisting seat and the yarn guide seat.

[0007] Furthermore, a yarn guide assembly is installed on the yarn guide seat. The yarn guide assembly is embedded in the yarn guide seat, and an arc-shaped hole is formed between the bottom of the yarn guide seat and the yarn guide assembly to allow yarn and airflow to pass through.

[0008] Furthermore, the yarn guide seat includes an extended ring, which is fitted into a sealing sleeve. A yarn guide tube is installed inside the sealing sleeve. The untwisting seat includes a stepped hole, which is fitted onto the sealing sleeve through the stepped hole. The axis of the untwisting seat coincides with the axis of the yarn guide tube.

[0009] Furthermore, a central hole is provided inside the untwisting seat, which is set along the length of the untwisting seat. The untwisting seat includes an air inlet and an air outlet, both of which are connected to the central hole. The air outlet is set closer to the yarn guide seat than the air inlet.

[0010] Furthermore, a yarn suction nozzle assembly is installed inside the untwisting seat, and the yarn suction nozzle assembly is inserted into the central hole.

[0011] Furthermore, the rotating cup holder assembly includes a seal, and the process air duct is inserted into the seal. The process air duct achieves a sealed connection with the rotating cup holder assembly through the seal, and the seal is a process air duct sealing sleeve.

[0012] A cleaning method for an automatic rotor cleaning mechanism: When the spinner is opened, i.e., the spinner housing assembly leaves the rotor seat assembly, and the rotor head stops rotating, the fibers and dust that were originally attached to the side wall of the rotor head under centrifugal force become loose. Compressed air enters the untwisting seat, passes through the false twisting disc, and enters the rotor head, blowing the loose fibers and dust inside the rotor head into the vortex cavity. When the spinner is closed, i.e., the spinner housing assembly approaches and adheres to the rotor seat assembly, the fibers and dust blown out in the vortex cavity are sucked into the process air duct, thereby completing the cleaning.

[0013] Furthermore, the blown fibers and dust are drawn out into the process waste disposal box through the process air duct under the action of a process negative pressure of 0.5-0.6MPa.

[0014] The beneficial effects of this invention are: it realizes automatic cleaning of the rotating cup, greatly reduces manual intervention, lowers labor costs, and solves the problems of low efficiency and high labor intensity of existing manual cleaning; the structural design is reasonable, the components are tightly connected and accurately positioned, ensuring smooth airflow transmission, and the overall structure takes into account both cleaning effect and operational stability.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1-4 As shown, an automatic rotor cleaning mechanism includes a spinning machine housing assembly 1, a rotor seat assembly 2, an untwisting assembly 5, and a yarn guide seat 11. The lower parts of the spinning machine housing assembly 1 and the rotor seat assembly 2 are rotatably connected by a pin. The rotor seat assembly 2 can rotate flexibly relative to the spinning machine housing assembly 1 to meet the angle adjustment requirements during cleaning and maintenance.

[0022] The rotor holder assembly 2 includes a rotor head 3, a vortex chamber 6, a process air duct 7, and a sealing element 23. The rotor head 3 is fixedly installed in the middle position of the rotor holder assembly 2 and has a condensation groove inside for fiber condensation and spinning. The vortex chamber 6 is located inside the rotor holder assembly 2 and communicates with the interior of the rotor head 3 to collect fibers and dust blown out during the cleaning process. One end of the process air duct 7 is sealed and connected to the vortex chamber 6, and the other end is connected to the process waste discharge box. The sealing element 23 is a process air duct sealing sleeve, which is fixedly installed on the rotor holder assembly 2. The process air duct 7 is inserted into the process air duct sealing sleeve, and the process air duct sealing sleeve achieves a sealed connection between the process air duct 7 and the rotor holder assembly 2, effectively preventing negative pressure leakage.

[0023] The yarn guide seat 11 is installed in a groove in the spinning machine housing assembly 1. This groove, designed according to the shape of the yarn guide seat 11, restricts its five degrees of freedom, allowing only the necessary up-and-down movement during assembly. The flexible channel 4 is installed into the spinning machine housing assembly 1, simultaneously fixing the yarn guide seat 11 in place. A false twist disc 9 is installed in the center of the flexible channel 4 via an interference fit. The outer periphery of the false twist disc 9 has twisting grooves, ensuring both the false twisting effect of the yarn and the passage of clean airflow. One end of the yarn guide seat 11 communicates with the false twist disc 9, and the other end is fixedly connected to the untwisting seat 12 via threads, ensuring a secure and well-sealed connection.

[0024] A sealing sleeve 14 is provided between the yarn guide seat 11 and the untwisting seat 12. The sealing sleeve 14 can be made of nitrile rubber, which has good sealing performance and aging resistance. A yarn guide assembly 10 is installed on the yarn guide seat 11 by embedding. After assembly, an arc hole with a diameter of 2-3 mm is formed at the bottom. This arc hole allows the yarn to pass through smoothly while ensuring the efficiency of compressed air flow. An extension ring 13 is provided at the end of the yarn guide seat 11. The extension ring 13 is integrally formed with the yarn guide seat 11 and is inserted into one end of the sealing sleeve 14. The sealing sleeve 14 provides positioning by elastic clamping. A yarn guide tube 15 is installed inside the sealing sleeve 14 by interference fit. The yarn guide tube 15 is made of stainless steel with a smooth surface to reduce airflow and yarn resistance. A stepped hole 16 is provided at the lower end of the untwisting seat 12. The untwisting seat 12 is fitted onto the other end of the sealing sleeve 14 through the stepped hole 16, ensuring the coaxiality of the two.

[0025] The untwisting seat 12 has a central hole 20 along its length, with a diameter of 5-8 mm. The untwisting seat 12 has an air inlet 18 and an exhaust outlet 19, both of which communicate with the central hole 20. A yarn suction nozzle assembly 17 is inserted into the central hole 20 of the untwisting seat 12. The top and bottom of the yarn suction nozzle assembly 17 are sealed to the inner wall of the untwisting seat 12, while the middle portion forms an airflow chamber that allows airflow. Gas enters through the air inlet 18, then into the airflow chamber, and finally into the yarn suction nozzle assembly 17. The airflow chamber formed by the untwisting seat 12 and the yarn suction nozzle assembly 17 both changes the airflow direction and provides pressurization.

[0026] When the rotor spinning machine needs rotor cleaning, the control system issues a cleaning command, the opening and closing cylinders act and engage the locking components, driving the spinner to open 10°, that is, the spinner housing assembly 1 rotates 10° relative to the rotor seat assembly 2. At the same time, the drive motor of the rotor head 3 stops working, and the rotor head 3 stops rotating quickly under the action of the braking mechanism. The fibers and dust that were originally attached to the side wall 22 and the condensation tank of the rotor head 3 are loosened due to the loss of centrifugal force.

[0027] Subsequently, the compressed air source is activated. Compressed air is connected to the air inlet 18 of the untwisting seat 12 via an air pipe, then enters the central hole 20 through the airflow cavity between the untwisting seat 12 and the yarn suction nozzle assembly 17. Part of the compressed air flows out through the exhaust port 19, and part enters the yarn guide tube 15. The compressed air is transmitted downward along the yarn guide tube 15, passing through the arc hole at the bottom of the yarn guide assembly 10 and the false twist disc 9, and finally enters the interior of the rotor cup head 3. After the compressed air collides with the bottom 21 of the rotor cup head 3, it disperses towards the condensation tank and side wall 22, creating a strong sweeping effect on loose fibers and dust, causing them to detach from the rotor cup head 3 and fall into the vortex chamber 6.

[0028] After purging, the opening and closing cylinder drives the spinner to close tightly, that is, the spinner housing assembly 1 rotates towards the rotor seat assembly 2, so that the flexible channel 4 fits against the rotor seat assembly 2, forming a seal for the vortex cavity 6. The rotor seat assembly 2 and the sealing element 23 fit tightly, so that the end of the process air duct 7 is connected to the vortex cavity 6 through the exhaust port 24. The process negative pressure system is activated, generating a negative pressure of 0.5-0.6MPa. Under the action of negative pressure, the fibers and dust in the vortex cavity 6 are sucked into the process waste removal box through the process air duct 7, completing one cleaning cycle. The vortex cavity 6 is equipped with a sealing ring 8, and the flexible channel 4 abuts against the sealing ring 8, thereby improving the sealing effect of the vortex cavity 6.

[0029] To ensure thorough cleaning, the opening, blowing, and negative pressure discharge process is repeated three times. After the three cleaning cycles are completed, the spinning machine remains closed, the rotor head 3 is restarted, and the rotor spinning machine resumes normal spinning operation. By repeating this process three times, it is ensured that fibers and dust inside the rotor and the condensing tank are completely removed, resulting in a stable and reliable cleaning effect, effectively reducing yarn breakage rate and improving yarn quality.

[0030] If manual cleaning or replacement of parts is required, the locking mechanism can be operated to disengage the spinning machine from the locking structure, allowing the spinning machine to open 90°.

[0031] The above description is merely a preferred embodiment of the present invention, and the scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
