Description

Technical Field

[0001] The invention relates to the technical field of spandex spinning equipment, in particular to an online cleaning device for a false twister. Background Art

[0002] my country is both the largest producer and consumer of spandex products. Dry spinning is currently the most widely used spandex production method worldwide. Dry-spun spandex yarn undergoes spinning, false twisting, oiling, drafting, and winding on a winder. The aperture within the metal chuck of the false twister is a spiral channel running from top to bottom. When a pressurized airflow is introduced from one end of the channel, the individual filaments in the tow are distorted by the high-speed airflow. The interaction of the spiral channel creates a false twist "balloon" similar to a braid. Due to its relatively complex structure, cleaning the false twister requires manual disassembly and assembly. The current false twister cleaning process includes: ① disassembling the false twister; ② soaking it in high-temperature DMAC for one hour; ③ cleaning it with clean water under ultrasonic guidance; ④ drying it with airflow; ⑤ laying the false twister flat in an oven and drying it for one hour; ⑥ assembling it with the false twister cavity and then installing it.

[0003] According to statistics, it takes at least two skilled workers 4 hours to complete the cleaning of the false twister on a winding machine, which is very time-consuming and inconvenient. Summary of the Invention

[0007] The water inlet of the pneumatic pump is connected to the output end of the three-way valve, and the input end of the three-way valve has two paths, one of which is connected to the clean water tank through the clean water pipe, and the other is connected to the washing solvent tank; the output end of the pneumatic pump is connected to the cleaning head water inlet pipe, the outlet of the cleaning head water inlet pipe is connected to the input end of the three-way air source connector, and the output end of the three-way air source connector is divided into two cleaning head water inlet pipes, which are respectively connected to the front end and the rear end of the false twister cavity;

[0008] The return pipe has two sections, one is a horizontal section and the other is a vertical section. The two sections are connected by a connecting elbow. A seal is provided at the outer end of the horizontal section. The vertical section of the return pipe is inserted into the washing solvent tank or the clean water tank. The horizontal section of the return pipe is provided on the periphery of the false twister cavity.

[0009] The horizontal section of the return pipe is provided with an inlet, and the two cleaning head water inlet pipes are respectively connected to the cleaning heads through the inlet.

During operation, the liquid sprayed by the cleaning head flows out through the false twister, and forms a reflux through the horizontal section of the return pipe, the connecting elbow, and the vertical section of the return pipe. When the washing solvent is turned on for cleaning, the vertical section of the return pipe is located in the washing solvent tank. When the clean water is turned on for cleaning, the vertical section of the return pipe is located in the clean water tank.

[0013] A drain valve is respectively provided at the bottom of the washing solvent tank and the clean water tank. The washing solvent tank, the clean water tank and the pneumatic pump are connected through a three-way valve and fixed on the vehicle body.

[0014] Two wheels are respectively installed at the front and rear of the bottom of the vehicle body, and a vehicle handrail is arranged at one end of the vehicle body to facilitate people to push and walk.

[0015] The online cleaning method of the false twister online cleaning device of the present invention comprises the following steps: during operation, compressed air is first introduced into the pneumatic pump; during the first cleaning, the vertical section of the return pipe is first placed in a washing solvent tank; then the three-way valve connected to the washing solvent tank is opened; the washing solvent is driven by the pneumatic pump to enter the false twister cavity through the water inlet pipe of the cleaning head to clean the false twister; the cleaned solvent flows back to the washing solvent tank through the return pipe; then the second cleaning is started, the vertical section of the return pipe is placed in a clean water tank; then the three-way valve is switched to the clean water tank; clean water is driven by the pneumatic pump to enter the false twister cavity through the water inlet pipe of the cleaning head to clean the false twister; the cleaned clean water flows back to the clean water tank through the return pipe; finally, the three-way valve is switched to the compressed air to blow dry the false twister and the false twister cavity; thus, the cleaning of the false twister is completed; and the device can be directly removed after the cleaning is completed.

[0016] The first cleaning process takes 5-8 minutes; the second cleaning process takes 5-8 minutes; and the drying process takes 5-8 minutes.

[0017] Beneficial effects: The present invention has the following advantages:

[0018] The present invention provides an online cleaning device for a spandex false twister. This device can clean oil and stains from the false twister without manually disassembling the false twister, thus enabling online cleaning of the spandex winding false twister. This device solves the current problems of inconvenient false twister disassembly, time-consuming cleaning, high labor intensity, and waste of personnel. The device has the advantages of good cleaning effect, convenience, and high cleaning efficiency. Using this online cleaning device for a spandex false twister eliminates the steps of US immersion, ultrasonic cleaning, drying, and O-ring installation for the spandex false twister, reducing the cleaning time from 4 hours to 0.5 hours, saving various costs per device per year.

[0019] By increasing the flow rate of the cleaning solvent, the inside of the cavity and the false sense organ can be cleaned more thoroughly, so that the stains can be washed away more quickly. By increasing the flow rate of clean water, the false sense organ can be cleaned more thoroughly.

[0020] The pneumatic pump, the washing solvent water tank and the clean water tank are fixedly connected to the vehicle body. Two front wheels and two rear wheels are installed at the bottom of the vehicle body. A vehicle handrail is provided at one end of the vehicle body to facilitate people to push and walk.
