Description

Technical Field

[0001] This invention relates to the field of nonwoven fabric preparation technology, specifically a system for preparing water-soluble fiber-reinforced needle-punched nonwoven fabric. Background Technology

[0002] Water-soluble fiber needle-punched nonwoven fabric is a type of nonwoven fabric that combines the properties of water-soluble fibers with the needle-punching process. It possesses characteristics such as solubility, high strength, and porous breathability, making it promising for applications in medical, environmental protection, and industrial filtration fields. The most significant feature of water-soluble fiber needle-punched nonwoven fabric is its solubility. This type of nonwoven fabric gradually dissolves upon contact with water or certain solvents, facilitating subsequent processing or recycling. Through the needle-punching process, water-soluble fiber needle-punched nonwoven fabric can form a relatively dense fiber structure, resulting in high strength. This makes it perform exceptionally well in applications requiring tensile strength.

[0003] However, due to the characteristics of the fiber material, water-soluble nonwoven fabrics are not suitable for high-strength needle punching processes. For example, water-soluble nonwoven fabric fibers have low hardness and weak tension, and are prone to fiber damage during high-density needle punching. Therefore, we propose a water-soluble fiber reinforced needle punching nonwoven fabric preparation system. Summary of the Invention

[0004] The purpose of this invention is to provide a system for preparing water-soluble fiber-reinforced needle-punched nonwoven fabrics, in order to solve the problems mentioned in the background art, such as low fiber hardness, weak tension, and easy fiber damage during high-density needle punching.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a water-soluble fiber-reinforced needle-punched nonwoven fabric preparation system, comprising: a worktable;

[0006] Also includes:

[0007] There are two needle beams.

[0008] Needle plate: The needle plate is located inside the worktable and is used to cooperate with the needle beam.

[0009] The linkage assembly consists of two components, symmetrically distributed about the central axis of the needle beams. The linkage assembly is positioned between the two needle beams and drives them to alternately insert into the nonwoven fabric. This intermittent insertion reduces the risk of fiber damage. The linkage assembly includes two drive gear plates, which are meshed with a drive gear that is rotatably connected to the worktable.

[0010] Each of the two needle beams has a set of needles fixedly connected to its bottom end, and the two sets of needles are distributed alternately.

[0011] The outer wall of the needle plate is provided with needle holes, and the positions of the needle holes correspond to the positions of the needles one by one.

[0012] The two transmission tooth plates are slidably connected with the workbench, and the bottom ends of the two transmission tooth plates are fixedly connected with the needle beams.

[0013] The rear ends of the two transmission tooth plates are fixedly connected with limiting sliding blocks, the longitudinal section shape of the limiting sliding block is set as a "T" shape, and the limiting sliding block is slidably connected with the workbench.

[0014] The top end of one of the limiting sliding blocks is fixedly connected with a transmission frame, the inside of the transmission frame is movably connected with a movable shaft, and the rear end of the movable shaft is fixedly connected with a movable handle.

[0015] The movable handle is rotatably connected with the workbench, the movable handle and the transmission gear are in the same vertical plane, and the rear end of the movable handle is provided with a servo motor.

[0016] The front and rear ends of the workbench are fixedly connected with fixed frames, and the end portions of the fixed frames are rotatably connected with compression rollers.

[0017] The present application has at least the following advantages:

[0018] Under the action of the linkage assembly, the two needle beams cooperate with each other, when the needles of one needle beam are inserted, the needles of the other needle beam are just lifted, and when the water-soluble non-woven fabric enters the working range of the next needle beam, the insertion position of the needles of this needle beam is between the last insertion positions. By reducing the distribution density of the needles, the risk of fiber damage caused by the low tension of the water-soluble non-woven fabric web is reduced, and the needle punching depth, frequency and other parameters are ensured to meet the process standards, so that the water-soluble non-woven fabric is processed, and the water-soluble fiber reinforced needle punched non-woven fabric is obtained.

[0033] Wherein, the servo motor 450 starts, drives the movable handle 440 to rotate, the movable handle 440 drives the movable shaft 430 to make the circular motion of the movable handle 440, the transmission shaft can drive the transmission frame 420 which is movably connected with it to slide inside the workbench 001, since the transmission frame 420 is fixed with the transmission gear plate 401 through limiting sliding, the transmission gear plate 401 slides up and down inside the workbench 001 reciprocatingly, and under the action of the transmission gear 402, the other transmission gear plate 401 is driven to slide synchronously and reversely, so that the two needle beams 002 move alternately and are spacedly punctured;

[0034] Wherein, the water-soluble fiber non-woven fabric enters the workbench 001 through the related conveying device, the conveying speed needs to be matched with the puncture speed, the puncture of the two needle beams 002 is alternately distributed, when the needle 210 of one needle beam 002 is punctured, the needle 210 of the other needle beam 002 is just lifted, and when the water-soluble non-woven fabric enters the working range of the next needle beam 002, the puncture position of the needle 210 of this needle beam 002 is between the last two puncture positions, by reducing the distribution density of the needle 210, the risk of fiber damage due to the low tension of the water-soluble non-woven fabric web can be reduced, and at the same time, the needle puncture depth, frequency and other parameters can be ensured to meet the process standards, so that the water-soluble non-woven fabric can be processed.
