Description

Technical Field

[0001] This utility model relates to the field of spunlace nonwoven fabric processing technology, specifically to a device for pre-treating abrasion-resistant fibers in spunlace nonwoven fabrics. Background Technology

[0002] Spunlace nonwoven fabric, also known as hydroentangled nonwoven fabric, is a type of fabric made by spraying high-pressure micro-streams of water onto one or more layers of fiber web, causing the fibers to entangle with each other, thereby strengthening the web and giving it a certain strength. The hydroentanglement process mainly utilizes high-pressure water to continuously spray the fiber web. After the water passes through the web, it is rebounded by the support curtain and penetrates and entangles the fibers again from different directions, forming numerous mechanical bonding points, thus strengthening the web. To achieve wear resistance, the fibers are pretreated.

[0003] In traditional technology, the fabric is passed through the machine and then coated with a chemical coating to make it wear-resistant. However, when the fabric is wound up by the machine, although the whole body is under tension and in a tight state, the surface does not have an uneven surface, making it difficult for the coating to be fully absorbed.

[0004] Therefore, it is particularly important to improve the existing spunlace nonwoven fabric abrasion-resistant fiber pretreatment device, design a new type of spunlace nonwoven fabric abrasion-resistant fiber pretreatment device to solve the above-mentioned technical defects, and improve the overall practicality of the spunlace nonwoven fabric abrasion-resistant fiber pretreatment device. Utility Model Content

[0005] The purpose of this invention is to provide a pretreatment device for abrasion-resistant fibers in spunlace nonwoven fabric. Through the overall design, two sets of friction rollers are controlled to reciprocate and come into contact with the spunlace fabric, creating an uneven surface that facilitates the absorption of chemical coatings, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

A moving block is slidably connected to the top of the mounting plate, and a lifting platform is fixedly connected to the bottom end of the mounting plate. The lifting platform has a stepped structure design. A drive plate is slidably connected to the top of the lifting platform. A guide seat is fixedly connected to one end of the drive plate, and a friction roller is rotatably connected inside the guide seat.

[0009] As a preferred embodiment of this utility model, the driven plate is fixedly connected to a fixed seat on the outside, the fixed seat has a groove inside, and a moving rod is slidably connected inside the groove.

[0010] As a preferred embodiment of this utility model, a support base is fixedly connected to the outside of the mounting plate and below the driven plate, a limit rod is fixedly connected inside the support base, and the moving rod extends to the outside of the limit rod and is rotatably connected to the limit rod.

[0011] As a preferred embodiment of this utility model, a connecting seat is fixedly connected to the top of the drive plate, and a receiving groove is provided inside the connecting seat. The end of the moving rod away from the waist groove extends into the receiving groove and is slidably connected to the receiving groove.

[0012] As a preferred embodiment of this utility model, an extension platform is fixedly connected to the outside of the machine body, a connecting pipe is rotatably connected to the inside of the extension platform, a flexible hose is fixedly connected to the inside of the connecting pipe, a storage box is fixedly connected to the bottom of the machine body, a water pump is fixedly connected to the end of the flexible hose away from the connecting pipe and located at the end of the storage box, and a nozzle is fixedly connected to the outside of the connecting pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, the recesses and protrusions inside the chute contact the positioning pin, enabling the driven plate to slide. The waist groove then squeezes the moving rod, causing the two ends of the moving rod to move in opposite directions, thereby generating a thrust on the receiving groove. Subsequently, the connecting seat generates a thrust on the drive plate. Through the repeated sliding of the moving block, the drive plate reciprocates, achieving synchronous movement of the friction roller. This friction then rubs against the fabric, damaging its surface structure and creating a fine uneven surface. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Example: Please refer to Figures 1-6 This utility model provides a technical solution:

[0025] A pretreatment device for abrasion-resistant fibers in spunlace nonwoven fabric includes a machine body 1. A unwinding roller 2 is rotatably connected to the right end of the machine body 1, and a take-up roller 3 is rotatably connected to the left end of the machine body 1. A heating frame 101 is fixedly connected between the machine body 1 and the take-up roller 2. A mounting plate 4 is fixedly connected to the inner wall of the machine body 1. A moving block 5 is slidably connected to the top of the mounting plate 4. A raising platform 6 is fixedly connected to the bottom end of the mounting plate 4. The raising platform 6 has a stepped structure design. A drive plate 7 is slidably connected to the top of the raising platform 6. One end of the drive plate 7 is fixedly connected to... The guide seat has a friction roller 8 rotatably connected inside. The spunlace nonwoven fabric to be processed is placed outside the unwinding roller 2, and then one end of it is pulled into the machine body 1 and the heating frame 101 in sequence. Finally, it is wound around the outside of the take-up roller 3. The take-up roller 3 rotates, which drives the entire fabric to move in a translational motion. The drive plate 7 slides back and forth outside the lifting platform 6 to realize the synchronous movement of the friction roller 8, which then rubs the fabric, destroys the surface structure of the fabric, and makes it have a slight unevenness.

[0026] Furthermore, in this embodiment, the movable block 5 has a sliding groove 9 inside, which is designed in a W-shape. A driven plate 10 is slidably connected to the outside of the mounting plate 4. One end of the driven plate 10 extends to the outside of the movable block 5. A positioning post 11 is fixedly connected inside the driven plate 10 and extends into the inside of the sliding groove 9. By connecting one end of the movable block 5 to the output end of the electric telescopic rod, the movable block 5 will slide outside the mounting plate 4. Then, the sliding groove 9 will press against the positioning post 11. The recess and protrusion inside the sliding groove 9 will contact the positioning post 11, thereby generating a thrust on the driven plate 10 and enabling the driven plate 10 to slide.

[0027] Furthermore, in this embodiment, a fixed seat 12 is fixedly connected to the outside of the driven plate 10. A waist groove 13 is provided inside the fixed seat 12. A movable rod 14 is slidably connected inside the waist groove 13. A support seat 15 is fixedly connected to the outside of the mounting plate 4 and below the driven plate 10. A limit rod 16 is fixedly connected inside the support seat 15. The movable rod 14 extends to the outside of the limit rod 16 and is rotatably connected to the limit rod 16. By sliding through the driven plate 10, the waist groove 13 squeezes the movable rod 14, and the middle of the movable rod 14 is provided by the limit rod 16 as a new force point, so that the movable rod 14 swings along the limit rod 16.

[0028] Furthermore, in this embodiment, a connecting seat 17 is fixedly connected to the top of the drive plate 7. The connecting seat 17 has a receiving groove 18 inside. The end of the moving rod 14 away from the waist groove 13 extends into the receiving groove 18 and is slidably connected to the receiving groove 18. When the moving rod 14 swings, the two ends of the moving rod 14 will move in opposite directions, thereby generating a thrust on the receiving groove 18. Then the connecting seat 17 will generate a thrust on the drive plate 7. Through the repeated sliding of the moving block 5, the drive plate 7 can reciprocate.

[0029] Furthermore, in this embodiment, an extension platform is fixedly connected to the outside of the body 1, a connecting pipe 19 is rotatably connected to the inside of the extension platform, a flexible hose is fixedly connected to the inside of the connecting pipe 19, a storage box is fixedly connected to the bottom of the body 1, a water pump is fixedly connected to the end of the flexible hose away from the connecting pipe 19 and located at the end of the storage box, a nozzle 20 is fixedly connected to the outside of the connecting pipe 19, a handle is fixedly connected to one end of the connecting pipe 19, a support plate 21 is fixedly connected to the end of the extension platform near the handle, and a limit plate is rotatably connected to the top of the support plate 21. 22. A spring 23 is fixedly connected to the outside of the limiting plate 22. A ratchet 24 is fixedly connected to the outside of the connecting tube 19 at a position corresponding to the limiting plate 22. By filling the inside of the storage box with a chemical agent that enhances wear resistance, the chemical agent is then conducted to the inside of the connecting tube 19 by a water pump, and finally sprayed out through the nozzle 20. The angle of the nozzle 20 can be directly adjusted by turning the handle. Then, the spring 23 returns to its original position, causing the limiting plate 22 to engage in the tooth groove of the ratchet 24, thus completing the limiting of the nozzle 20 after angle adjustment.

[0030] In this embodiment, the specific implementation scenario is as follows: the spunlace nonwoven fabric to be processed is placed outside the unwinding roller 2, and then one end of it is sequentially pulled into the machine body 1 and the heating frame 101. Finally, it is wound around the outside of the take-up roller 3. The take-up roller 3 rotates, causing the entire fabric to move horizontally. One end of the moving block 5 is connected to the output end of the electric telescopic rod. The moving block 5 then slides outside the mounting plate 4, and the groove 9 presses against the positioning post 11. The recess and protrusion inside the groove 9 contact the positioning post 11, thereby generating a thrust on the driven plate 10, causing the driven plate 10 to slide. The waist groove 13 presses against the moving rod 14, and the middle of the moving rod 14 receives a new force point provided by the limiting rod 16, causing the moving rod 14 to move along the limiting rod 16. The moving rod 14 swings, and the two ends of the moving rod 14 move in opposite directions, which in turn pushes the receiving groove 18. Then the connecting seat 17 pushes the drive plate 7. Through the repeated sliding of the moving block 5, the drive plate 7 reciprocates, and the friction roller 8 moves synchronously, which in turn rubs the fabric, destroying the surface structure of the fabric and making it have a slight unevenness. The storage box is filled with a chemical agent that improves abrasion resistance. Then the chemical agent is transferred to the inside of the connecting pipe 19 by the water pump. Finally, it is sprayed out through the nozzle 20. The angle of the nozzle 20 can be directly adjusted by turning the handle. Then the spring 23 returns to its original position, which causes the limiting piece 22 to engage in the tooth groove of the ratchet 24, completing the limiting after the nozzle 20 angle is adjusted. Finally, the chemical agent is heated by the heating frame 101 to complete the abrasion resistance treatment.
