Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric raw material pretreatment, in particular to a melt-blown non-woven fabric raw material pretreatment device. Background Art

[0002] Meltblown nonwoven fabric is a nonwoven fabric produced by the meltblowing process. It is widely used in medical, sanitary and filtration fields. Its manufacturing process heats thermoplastic polymers to a molten state and sprays them through a nozzle to form fine fibers. These fibers cross-link with each other after cooling to form fabric. The main raw material of meltblown nonwoven fabric is usually polypropylene (PP) because of its excellent chemical stability and biocompatibility. In addition, polyester (PET) and polyurethane (PU) can also be used to meet the needs of different applications. Due to its good filtration performance and breathability, meltblown nonwoven fabrics are widely used in protective products such as masks.

[0003] Currently, when processing meltblown nonwoven fabrics, the raw materials may have uneven particle sizes, which may affect the melt flowability during the meltblowing process, resulting in inconsistent fiber diameters, which in turn affects the product's filtration performance, strength and appearance, and reduces the quality and reliability of the final product.

[0026] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them.

[0027] The present invention will be further described below with reference to the embodiments.

[0028] Embodiment: A melt-blown non-woven fabric raw material pretreatment device comprises a box body 1 and a screening box 5 arranged inside the box body 1, and a guide hopper 11 is fixedly installed at the bottom of the box body 1, and a fixed rod 8 is rotatably installed on the side wall of the inner cavity of the box body 1, and a driving member is provided on the top of the fixed rod 8. When the fixed rod 8 rotates, the screening box 5 can be driven to move back and forth by the driving member, thereby screening its raw materials. The surface of the fixed rod 8 is also provided with a cleaning member. When the fixed rod 8 rotates, the screened raw materials can be cleaned and discharged to the guide hopper 11 through the cleaning member. The cleaning member includes a fixed sleeve 9 fixedly installed on the surface of the fixed rod 8, and a plurality of scrapers 10 are fixedly installed on the surface of the fixed sleeve 9. A motor 13 is fixedly installed at the bottom of the box body 1, and the bottom of the fixed rod 8 rotates through the box body 1, and the motor 13 is fixedly installed on the bottom of the fixed rod 8 through the output shaft. A plurality of support frames 2 are also fixedly installed on the surface of the box body 1 to raise the box body 1 so that the guide hopper 11 can discharge materials.

[0029] Specifically, the raw materials to be processed can be poured into the screening box 5 first, and the motor 13 is used for output to drive the rotation of the fixed rod 8, and cooperate with its driving part to drive the screening box 5 to move back and forth, so that the raw materials poured into the screening box 5 are evenly spread, so that the raw materials with uniform particle size can enter the box body 1 below from the screening box 5, and while the fixed rod 8 rotates, the fixed sleeve 9 on the surface of the fixed rod 8 can be synchronously driven to rotate, so that the multiple groups of scrapers 10 on the surface of the fixed sleeve 9 can be used to scrape the raw materials entering the box body 1 to the guide hopper 11 for discharge, so as to facilitate the centralized collection of the raw materials after the screening process;

[0030] Specifically, the driving member includes a rotating wheel 7 fixedly mounted on the top of the fixed rod 8, a connecting rod 6 is rotatably mounted on the top of the rotating wheel 7, and one end of the connecting rod 6 away from the rotating wheel 7 is rotatably mounted on one side of the screening box 5, and two groups of sliding sleeves 12 are fixedly mounted on both sides of the screening box 5, and the inner cavity side walls of the two groups of sliding sleeves 12 are slidably mounted with guide rods 4, and both ends of the guide rods 4 are fixedly mounted with fixing frames 3, and the surfaces of the fixing frames 3 are fixedly mounted on the inner cavity side walls of the box body 1;

[0031] Specifically, when the fixed rod 8 is driven to rotate by the output of the motor 13, the rotating wheel 7 on the top of the fixed rod 8 can be driven to rotate. Because its screening box 5 is slidably installed on the guide rod 4 in the fixed frame 3 through multiple sets of sliding sleeves 12 on its surface, it is limited and guided by its guide rod 4. Therefore, when the rotating wheel 7 rotates, the connecting rod 6 rotatably installed on its top can pull the screening box 5 to perform a linear reciprocating motion, so that the raw materials in the screening box 5 can be evenly shaken out, thereby screening the raw materials.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
