Description

Technical Field

[0001] The present invention relates to the technical field of textile production equipment, and more specifically, the present invention relates to a hydroentangling device and processing technology for non-woven fabric production and processing. Background Art

[0002] Non-woven fabric, also known as non-woven cloth, needle-punched cotton, needle-punched non-woven fabric, etc., is produced using polyester fiber and polyester fiber (abbreviation: PET) materials and is made through a needle-punching process. It can be made into different thicknesses, handfeel, hardness, etc. Non-woven fabric has the characteristics of moisture-proof, breathable, flexible, light, flame-retardant, non-toxic and odorless, low price, recyclable, etc. It can be used in different industries, such as sound insulation, heat insulation, electric heating sheets, masks, clothing, medical use, filling materials, etc.; and hydroentangled non-woven fabric is to spray high-pressure fine water jets onto one or more layers of fiber webs, so that the fibers are entangled with each other, so that the fiber web is strengthened and has a certain strength, and the obtained fabric is hydroentangled non-woven fabric. Its fiber raw materials are widely sourced, and can be polyester, nylon, polypropylene, viscose fiber, chitin fiber, ultra-fine fiber, tencel, silk, bamboo fiber, wood pulp fiber, seaweed fiber, etc. The principle of strengthening the fiber web by the hydroentangling method is similar to the needle-punching process, but instead of using a needle, it uses multiple fine water jets generated by high pressure - a hydroentangling machine sprays the fiber web. After the water jet passes through the fiber web, it is rebounded by the supporting mesh curtain and penetrates the fiber web again. Thus, the fibers in the fiber web are displaced, penetrated, entangled and held together under the hydraulic action of the high-speed water jets in different directions, so that the fiber web is strengthened.

[0003] In the prior art, the hydroentangling device for non-woven fabric usually directly injects high-pressure water source, which increases the burden on the water pump, thus affecting the service durability and stability of the entire hydroentangling device. Summary of the Invention

The technical problem to be solved by the present invention is: how to ensure the service durability and stability of the hydroentangling device.

[0005] To achieve the above object, the present invention provides the following technical solution: A hydroentangling device for non-woven fabric production and processing, including a carrier box base, a hydroentangling treatment mechanism is fixedly provided on the top of the carrier box base, a gap for passing non-woven fabric is left between the bottom end of the hydroentangling treatment mechanism and the top of the carrier box base, a sub-compartment water replenishing component is provided at the top end of the hydroentangling treatment mechanism, a water replenishing pipe is provided at the center of the top end of the hydroentangling treatment mechanism, an air inlet pipe is also provided on one side of the hydroentangling treatment mechanism, and a drain pipe is provided on one side of the carrier box base;

[0006] The hydroentangling treatment mechanism includes an air storage tank and a water distribution tank. The air storage tank and the water distribution tank are integrally formed. The interior of the water distribution tank is provided with a water storage cavity, and the interior of the air storage tank is provided with a pressurization cavity. The water storage cavity is connected to the pressurization cavity. The bottom end of the air storage tank is provided with a water outlet, and a hydroentangling head is arranged above the water outlet;

[0007] The compartment water replenishing component includes a partition paddle and a driving motor. The partition paddle is arranged inside the water storage cavity. The water storage cavity is divided into three relatively isolated liquid storage spaces by the partition paddle. The driving motor is fixedly arranged on the outer wall of the water distribution tank, and the output shaft of the driving motor is connected to the partition paddle. A backstop is also arranged on the output shaft of the driving motor to prevent the partition paddle from reversing under high air pressure.

[0008] In a preferred embodiment, the water replenishing pipe penetrates through the water distribution tank and is connected to the water storage cavity. The water replenishing pipe is connected to the drain pipe, and a water pump is additionally arranged at the connection;

[0009] The air inlet pipe movably penetrates through the air storage tank and is connected to the pressurization cavity. An air pump is additionally arranged at the other end of the air inlet pipe to add gas and increase pressure to the pressurization cavity.

[0010] In a preferred embodiment, air flow guiding plates are fixedly arranged at both ends of the bottom end of the air storage tank, and the cross-sectional shape of the air flow guiding plates is set to be arc-shaped.

[0011] In a preferred embodiment, the bottom of the carrier box includes a seat body. A water storage cavity is arranged inside the seat body. A water collecting trough is arranged on the top of the seat body. A plurality of water distribution holes are evenly arranged between the water collecting trough and the water storage cavity. The water collecting trough and the water storage cavity are communicated by the water distribution holes. Air dispersion holes are also arranged between the water storage cavity and the top of the seat body;

[0012] The water storage cavity is arranged in alignment with the water outlet, and foot posts are fixedly arranged at the bottom end of the seat body.

[0013] In a preferred embodiment, a filtering mechanism is also arranged at the position of the water replenishing pipe or the drain pipe. The filtering mechanism includes a shell and a filtering sponge arranged inside the shell, and is used for filtering short fibers in water.

[0014] The present invention also includes a hydroentangling processing technology for non-woven fabric production and processing. The specific processing steps are as follows:

[0015] S1. Installation of non-woven fabric: Use a winding machine or a transmission roller to pass the non-woven fabric to be processed through the hydroentangling device, so that the non-woven fabric is horizontally distributed at the gap position between the base of the carrier box and the hydroentangling treatment mechanism;

[0016] S2: The water pump between the water replenishing pipe and the drain pipe works to transport the water in the water storage cavity to the position of the water storage cavity;

[0017] S3: During this period, the driving motor and the air pump work synchronously;

[0018] S4: The drive motor operates to drive the partition paddle to rotate. When the liquid storage space formed by the two blades of the partition paddle and the water storage cavity is in communication with the water supply pipe, the water supply pipe stores water in this liquid storage space. When the water-filled liquid storage space rotates with the partition paddle and is connected to the pressurization cavity, it falls into the pressurization cavity under the action of the self-weight of the water. This process is repeated continuously to replenish water into the pressurization cavity;

[0019] S5: The air pump operates to pressurize the pressurization cavity, and through the water jet head, high-pressure fine water columns are ejected from the air dispersion holes to continuously perform water jet work on the non-woven fabric transmitted at the bottom;

[0020] S6: The high air pressure state in the pressurization cavity acts on the partition paddle. Under the action of the check valve, it prevents the reverse rotation of the partition paddle; Compared with the traditional direct water pipe transportation, it effectively avoids the inability to replenish water smoothly due to the reaction of air pressure. Moreover, the traditional method of only replenishing water through the water pipe cannot meet the pressure required by the water jet head, affecting the water jet effect;

[0021] S7: The water that has completed the water jet work is gathered by the water collection tank, and then flows back to the water storage cavity through the water distribution holes. After the water with added gas is impacted, the gas flows upward in a reverse direction through the water distribution holes and the air dispersion holes. Limited by the air flow guiding plate, an air flow is generated in a nearly horizontal direction, accelerating the air flow speed around the non-woven fabric after water jetting, achieving a certain drying and water droplet splashing effect. And the water loss can be supplemented into the water storage cavity from the position of the water collection tank to ensure the smooth progress of the water jet work;

[0022] S8: The water storage cavity gathers the water after water jetting, and then through the transmission of the drain pipe, continuous water jet work is carried out.

[0023] Technical effects and advantages of the present invention:

[0024] Through the combined use of the water jet treatment mechanism and the multi-compartment water replenishing component in the present invention, the drive motor operates to drive the partition paddle to rotate. When the liquid storage space formed by the two blades of the partition paddle and the water storage cavity is in communication with the water supply pipe, the water supply pipe stores water in this liquid storage space. When the water-filled liquid storage space rotates with the partition paddle and is connected to the pressurization cavity, it falls into the pressurization cavity under the action of the self-weight of the water, effectively avoiding the inability to replenish water smoothly due to the reaction of air pressure. Moreover, the traditional method of only replenishing water through the water pipe cannot meet the pressure required by the water jet head, affecting the water jet effect. The water that has completed the water jet work is gathered by the water collection tank. After the water with added gas is impacted, the gas flows upward in a reverse direction through the water distribution holes and the air dispersion holes to generate an air flow in a nearly horizontal direction, accelerating the air flow speed around the non-woven fabric after water jetting, achieving a certain drying and water droplet splashing effect, and further reducing the air pressure in the gathered water, reducing the burden on the water pump, thereby improving the service durability and stability of the entire water jet device.

[0039] As Figures 1-5 shown, the implementation method is specifically: a hydroentangling processing technology for non-woven fabric production and processing. The specific processing steps are as follows:

[0040] Installation of non-woven fabric: Use a winding machine or a transmission roller to pass the non-woven fabric to be processed through the hydroentangling device, so that the non-woven fabric is horizontally distributed at the gap position between the carrier box base 1 and the hydroentangling treatment mechanism 2;

[0041] The water pump between the water replenishing pipe 4 and the drain pipe 6 works to transport the water in the water storage cavity 15 to the position of the water storage cavity 23;

[0042] During this period, the driving motor 32 and the air pump work synchronously;

[0043] The driving motor 32 works to drive the partition paddle 31 to rotate. When the liquid storage space formed by the two paddle blades of the partition paddle 31 and the water storage cavity 23 is connected to the water replenishing pipe 4, the water replenishing pipe 4 stores water in this liquid storage space. When the water-filled liquid storage space rotates with the partition paddle 31 and is connected to the pressurization cavity 24, it falls into the pressurization cavity 24 under the action of the self-weight of the water.

[0045] The high air pressure state in the pressurized cavity 24 acts on the partition paddle 31, and under the action of the check valve 33, the reverse rotation of the partition paddle 31 is avoided; compared with the traditional direct water pipe conveyance, it effectively avoids the inability to smoothly replenish water due to the reaction of air pressure, and the traditional water replenishment only by the water pipe cannot meet the pressure required by the hydroentangling head 27, affecting the hydroentangling effect;

[0046] The water that has completed the hydroentangling work is gathered by the water collecting tank 12, and then flows back to the water storage cavity 15 through the water distribution holes 13. After the aerated water is impacted, the gas flows upward in a reverse manner through the water distribution holes 13 and the air dispersion holes 14. Limited by the position of the air flow guiding plate 25, an air flow is generated in a nearly horizontal direction, accelerating the air flow speed around the hydroentangled non-woven fabric, achieving a certain drying and water droplet splashing effect, and the water loss can be replenished into the water storage cavity 15 from the position of the water collecting tank 12 to ensure the smooth progress of the hydroentangling work;
