Description

Technical Field

[0001] This utility model belongs to the technical field of nonwoven fabric production equipment, specifically relating to a self-cleaning feeding device for nonwoven fabric production. Background Technology

[0002] Nonwoven fabric supply equipment uses conveyor belts extensively, but the raw materials for nonwoven fabrics are mostly short fibers, which can cause cotton jamming (fibers rub and become entangled between the conveyor belt and the mechanical guard plate). Over time, this can cause white fibers to turn yellow or black, collectively known as impurities, affecting product quality, requiring machine shutdown for cleaning, and also affecting production utilization.

[0003] This invention improves the structure of the conveyor mechanism to automatically clean up fiber impurities accumulated on the edges of the conveyor belt during operation, thereby improving quality, reducing downtime, and ensuring production uptime. Utility Model Content

[0004] The purpose of this invention is to provide a self-cleaning feeding device for nonwoven fabric production, in order to solve the above-mentioned problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A self-cleaning feeding device for nonwoven fabric production is installed on the mechanical guard plate of a nonwoven fabric feeding equipment. The inner side of the mechanical guard plate is a conveyor belt and includes a fiber scraping mechanism. One end of the fiber scraping mechanism is fixedly connected to the mechanical guard plate, and the other end of the fiber scraping mechanism extends towards the surface of the conveyor belt and extends above the conveyor belt, with a distance from the edge of the conveyor belt. An angle is formed between the fiber scraping mechanism and the long side of the conveyor belt, and the angle does not exceed 90 degrees. At least two fiber scraping mechanisms are provided, located on both sides of the conveying direction of the conveyor belt.

[0007] Optionally, two fiber scraping mechanisms may be provided.

[0008] Optionally, the conveyor belt includes a loading surface and a venting surface, and the fiber scraping mechanism is located above the venting surface.

[0009] Optionally, the fiber scraping mechanism is provided with a brush on the end face facing the conveyor belt, the brush is arranged perpendicular to the surface of the conveyor belt, and the end of the brush does not contact the surface of the conveyor belt.

[0010] Optionally, the distance from the other end of the fiber scraping mechanism to the edge of the conveyor belt is between one-fifth and one-quarter of the width of the conveyor belt.

[0011] Optionally, the included angle is between 30 degrees and 60 degrees.

[0012] Optionally, a clamping mechanism is provided at one end of the fiber scraping mechanism near the mechanical guard plate, and the fiber scraping mechanism is fixedly connected to the mechanical guard plate through the clamping mechanism.

[0013] Beneficial effects: This utility model discloses a self-cleaning feeding device for nonwoven fabric production. A fiber scraping mechanism is installed above the conveyor belt to scrape off short fibers remaining on the conveyor belt surface, preventing the accumulation of short fibers between the conveyor belt and the mechanical guard plate, which can cause fiber jamming and affect product quality and production utilization. The structure of this utility model is simple, requiring only one fiber scraping mechanism to be installed on the mechanical guard plate. It is applicable to the retrofitting of all existing nonwoven fabric feeding equipment without the need to replace the original equipment, and has widespread applicability.

[0020] Example

[0021] like Figures 1-2 As shown, this embodiment provides a self-cleaning feeding device for nonwoven fabric production, which is installed on the mechanical guard plate 1 of the nonwoven fabric feeding equipment. The inner side of the mechanical guard plate 1 is a conveyor belt 2, including a fiber scraping mechanism 3. One end of the fiber scraping mechanism 3 is fixedly connected to the mechanical guard plate 1, and the other end of the fiber scraping mechanism 3 extends towards the surface of the conveyor belt 2 and extends above the conveyor belt 2, with a distance from the edge of the conveyor belt 2. An angle 4 is formed between the fiber scraping mechanism 3 and the long side of the conveyor belt 2, and the angle 4 does not exceed 90 degrees. At least two fiber scraping mechanisms 3 are provided, respectively located on both sides of the conveying direction of the conveyor belt 2.

[0022] In existing nonwoven fabric feeding equipment, a mechanical guard plate 1 is installed around the perimeter of the conveyor belt 2, and a transparent cover plate is installed above the mechanical guard plate 1. The conveyor belt 2 is located in the space between the mechanical guard plate 1 and the transparent cover plate. One end of the conveyor belt 2 is the inlet and the other end is the outlet. During the feeding process of the nonwoven fabric feeding equipment, most of the long fibers will gather in the middle of the conveyor belt 2 and be conveyed along the conveyor belt 2, while the short fibers will gather on both sides of the conveyor belt 2. Since the surface of the conveyor belt 2 is relatively rough, with long-term use, the short fibers on both sides of the conveyor belt 2 will accumulate more and more, getting stuck between the conveyor belt 2 and the mechanical guard plate 1, eventually causing the cotton jamming phenomenon, affecting product quality and production utilization rate.

[0023] In this embodiment, by adding a fiber scraping mechanism 3 to the mechanical guard plate 1, and having at least two fiber scraping mechanisms 3 respectively located on both sides of the conveyor belt 2 in the conveying direction, the above-mentioned problems in the prior art are solved; specifically, the function of the fiber scraping mechanism 3 in this utility model is to scrape off the short fibers gathered on both sides of the conveyor belt 2, and the scraped short fibers fall along the gap between the conveyor belt 2 and the mechanical guard plate 1 to the recycling device below for recycling and reuse.

[0024] One end of the fiber scraping mechanism 3 is fixedly connected to the mechanical guard plate 1, and the other end extends towards the conveyor belt 2 and extends above the conveyor belt 2, with a distance from the edge of the conveyor belt 2; the fiber scraping mechanism 3 and the long side of the conveyor belt 2 form an angle 4, specifically, the angle 4 does not exceed 90 degrees.

[0025] When using it, first adjust the angle of the fiber scraping mechanism 3, then install the fiber scraping mechanism 3 on the mechanical guard plate 1, and start the non-woven fabric feeding equipment.

[0026] An angle adjustment mechanism can also be set between the fiber scraping mechanism 3 and the mechanical guard plate 1. The angle adjustment mechanism can be used to easily adjust the included angle 4 between the fiber scraping mechanism 3 and the long side of the conveyor belt 2 to adapt to the needs of more scenarios.

[0027] In one preferred embodiment, two fiber scraping mechanisms 3 are provided, and the two fiber scraping mechanisms 3 are symmetrically arranged on both sides of the conveyor belt 2. Of course, the number of fiber scraping mechanisms 3 and whether they are symmetrically arranged are not limited. The number of fiber scraping mechanisms 3 on both sides can be multiple, or they can be arranged asymmetrically.

[0028] When the fiber scraping mechanism 3 is located on the carrying surface of the conveyor belt 2, it may accidentally scrape off long fibers. To avoid this, in one preferred embodiment, the conveyor belt 2 includes a carrying surface and an empty surface 21, with the fiber scraping mechanism 3 located above the empty surface 21. Specifically, the carrying surface is used to transport fibers, and the empty surface 21 is the empty state after transport. The carrying surface and the empty surface 21 are not two separate surfaces, but rather represent two different states. When the surface carries fibers, it is the carrying surface; when the surface does not carry fibers, it is the empty surface 21. Simply put, the front of the conveyor belt 2 is the carrying surface, and the back of the conveyor belt 2 is the empty surface 21. The fiber scraping mechanism 3 is located on the back of the conveyor belt 2. This design can reduce the phenomenon of long fibers being accidentally scraped off.

[0029] In one of the alternative implementations, see Figure 2 The fiber scraping mechanism 3 is provided with a brush 5 on the end face facing the conveyor belt 2. The brush 5 is arranged perpendicular to the surface of the conveyor belt 2, and the end of the brush 5 does not contact the surface of the conveyor belt 2.

[0030] Specifically, the end of the brush 5 does not contact the surface of the conveyor belt 2, so as to avoid friction between the brush 5 and the surface of the conveyor belt 2 during the conveying process, which would affect the transportation of the conveyor belt 2.

[0031] In one alternative implementation, the distance from the other end of the fiber scraping mechanism 3 to the edge of the conveyor belt 2 is between one-fifth and one-quarter of the width of the conveyor belt 2. Too large a distance will increase the risk of accidentally scraping long fibers, while too small a distance may result in short fibers not being scraped thoroughly. Therefore, in specific applications, the length of the fiber scraping mechanism 3 should be reasonably set according to the width of the conveyor belt 2.

[0032] In one preferred embodiment, the included angle 4 is between 30 degrees and 60 degrees.

[0033] In one preferred embodiment, a clamping mechanism is provided at one end of the fiber scraping mechanism 3 near the mechanical guard plate 1, and the fiber scraping mechanism 3 is fixedly connected to the mechanical guard plate 1 through the clamping mechanism. The clamping mechanism facilitates the fixing and disassembly of the fiber scraping mechanism 3. During installation, the clamping mechanism can be directly clamped onto the mechanical guard plate 1. When the fiber scraping mechanism 3 is damaged and needs to be replaced, the clamping mechanism can be directly pressed to remove it. It is very convenient to use.

[0034] This utility model discloses a self-cleaning feeding device for nonwoven fabric production. A fiber scraping mechanism 3 is provided above the conveyor belt 2. The fiber scraping mechanism 3 scrapes off the short fibers remaining on the surface of the conveyor belt 2, avoiding the accumulation of short fibers between the conveyor belt 2 and the mechanical guard plate 1 after long-term use, which can cause cotton jamming and affect product quality and production utilization. The structure of this utility model is simple, requiring only one fiber scraping mechanism 3 to be installed on the mechanical guard plate 1. It is applicable to the modification of all existing nonwoven fabric feeding equipment without replacing the nonwoven fabric feeding equipment, and has universal promotion significance.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
