Description

Technical Field

[0001] This utility model belongs to the field of dry nonwoven fabric production and processing technology, and specifically refers to a fiber opening and mixing device. Background Technology

[0002] refer to Figure 1 As shown, a traditional dry nonwoven fabric opening and mixing production line consists of an opening machine, a weighing device, a cotton box, an opening machine, and an air distribution system. The opened and mixed fibers are conveyed and distributed by air to the feeding cotton box of the subsequent web forming equipment. This process is suitable for processing products with a single fiber variety, and the product only requires the equipment to achieve a certain degree of opening.

[0003] As product application conditions become increasingly demanding, pure spun products using a single fiber variety can no longer meet application requirements. Therefore, blended products using multiple fiber varieties have emerged. Besides opening density, the most important requirement for equipment in blended products is the uniformity of mixing multiple raw materials. Traditional blending boxes mainly rely on the airflow of cyclones to mix fibers. After being opened, the fibers are fed into the cyclone device adjacent to the blending box through pipes. For two or more fibers with significantly different specific gravities, the force of the cyclone will also differ, causing fibers with different specific gravities to separate again within the mixed fiber bundle. In reality, the crimp, softness, coefficient of friction, and specific gravity of various fibers in nonwoven materials are all different, making it impossible for traditional opening and cleaning blending equipment to mix multiple fiber varieties of raw materials uniformly. Utility Model Content

[0004] The main purpose of this utility model is to provide a fiber opening and mixing device to solve the problems existing in the prior art. It is suitable for uniformly mixing fibers with different physical properties to improve the appearance and weight uniformity of products.

[0005] To achieve the above objectives, the solution of this utility model is:

[0006] A fiber opening and mixing device includes a frame located at the end of an opening curtain, and five opening rollers mounted on the frame. Each opening roller has a plurality of carding beaters evenly arranged on its circumference. The distance between adjacent carding beaters along the axial direction of the same opening roller is defined as the beater spacing. The beater spacing of the five opening rollers gradually decreases along the fiber's forward direction. The five opening rollers are divided into two groups: the first group consists of three opening rollers tilted upwards, and the second group consists of two opening rollers tilted downwards. The mixed fibers are transported via an airflow distribution pipe to a horizontally laid and vertically picked-up curtain in a blending box.

[0007] The fiber opening and mixing device further includes a feeding conveyor device located at the input end of the frame, the feeding conveyor device having a weighing function, and a feeding device located inside the frame and connected to the feeding conveyor device, both the feeding conveyor device and the feeding device being belt conveyors.

[0008] The value range for the distance between the thugs is set to 10~15cm.

[0009] Of the five opening rollers, the slope of the three opening rollers in the first group is set to 45°.

[0010] After adopting the above technical solution, the present invention has the following technical effects:

[0011] This invention allows for differentiated opening speeds and mixing times for different quantities of fiber raw materials to be processed, achieving a better mixing effect compared to corner nail curtains. The mixed fibers are directly transported to the horizontally laid and directly picked-up curtain in the cotton blending box via an airflow distribution pipeline, avoiding secondary separation of fibers with large specific gravities due to cyclone action. After fine opening, the fiber clumps are transported to the subsequent cotton storage box for further processing. Structurally, this invention eliminates the corner nail curtain and cyclone device, adding two sets of five working rollers. The fiber conveying position after blending is adjusted from adjacent to the cyclone device to the horizontally laid and directly picked-up position, improving the uniformity of mixing multiple fibers.

[0017] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0018] refer to Figure 2-3As shown, this utility model discloses a fiber opening and mixing device, including a frame 1 set at the end of the opening curtain, and five opening rollers 2 installed on the frame 1. Each opening roller 2 has a number of carding beaters 3 evenly arranged on its circumference. The distance between adjacent carding beaters 3 along the axial direction of the same opening roller 2 is defined as the beater distance D. The beater distance D of the five opening rollers 2 gradually decreases along the fiber's forward direction, that is, the carding beaters of the opening rollers 2 are configured according to the principle of first sparse and then dense. At the same time, the five opening rollers 2 are divided into two groups. The first group consists of three opening rollers 2 tilted upwards, and the second group consists of two opening rollers 2 tilted vertically downwards, thus making the opening rollers 2 have a triangular layout of tilting upwards first and then vertically downwards. The mixed fibers are transported to the horizontally laid and vertically picked-up curtain of the mixing box through an airflow distribution pipe.

[0019] Through the above scheme, this utility model can set differentiated opening speed and mixing time for different quantities of fiber raw materials to be processed, thereby achieving a better mixing effect than the corner nail curtain; the mixed fibers are directly transported to the horizontally laid and directly picked up leather curtain of the cotton mixing box through the airflow distribution pipeline, which can avoid secondary separation of various fibers with large specific gravity differences after mixing due to the cyclone effect. After fine opening, the fiber clumps are transported to the cotton storage box in the later stage for further circulation and processing; in terms of structure, this utility model abandons the opening corner nail curtain and cyclone device, and adds two sets of five working rollers 2. The fiber conveying position after mixing is adjusted from adjacent to the cyclone device to the horizontally laid and directly picked up position, which improves the mixing uniformity of various fibers.

[0020] The following are specific embodiments of the present invention.

[0021] This utility model also includes a feeding conveyor 4 installed at the input end of the frame 1, the feeding conveyor 4 having a weighing function, and a feeding device 5 installed inside the frame 1 and connected to the feeding conveyor 4. Both the feeding conveyor 4 and the feeding device 5 are belt conveyors.

[0022] The value range of the above-mentioned spacing D between the thugs is set to 10~15cm.

[0023] Of the five opening rollers 2 mentioned above, the slope of the three opening rollers 2 in the first group is set to 45°.

[0024] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
