Description

Technical Field

[0001] The invention relates to the technical field of textile processing, and in particular to a hemp fiber degumming treatment device and method. Background Art

[0002] Hemp fiber is a general term for fibers obtained from various hemp plants. Hemp fiber can be used as a textile raw material to weave various cool fine linen, summer cloth, etc. In the existing hemp fiber extraction process, hemp fiber often contains impurities such as hemp meat and hemp skin. These impurities will not only affect the subsequent weaving, but also easily cause the hemp fiber to break after drying.

[0003] Hemp fibers are bonded together by colloids. When making hemp fibers, the colloids must be removed to separate the fibers, which is called the degumming process. Degumming hemp raw materials is the most basic and critical processing process in the hemp textile industry. In this process, it is usually necessary to remove the non-cellulose substances (collectively referred to as colloids) contained in the raw hemp to obtain pure hemp fibers for textiles. Therefore, degumming is a basic process in the hemp textile industry, and its quality directly affects the texture and quality of the textiles.

[0004] For a long time, chemical degumming has been the dominant method, but no matter how it is improved, chemical degumming cannot completely overcome its own defects, such as high cost, high energy consumption, low fiber quality, poor quality, serious environmental pollution, etc., especially its huge pollution to the environment makes hemp textile enterprises face the danger of suspension of production and closure. Biological degumming is a newly developed emerging technology that can overcome the above shortcomings. There are two types of hemp fiber biological degumming: microbial degumming and enzymatic degumming. Enzymatic degumming requires enzyme preparations, which are not easy to obtain and have high costs, which limits its application and promotion. And because the ramie colloid component is complex, the degumming ability of one or several biological enzymes is limited, and its degumming effect is also difficult to control.

[0038] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0039] See also Figure 1-6 As shown, an embodiment of the present invention provides a hemp fiber degumming processing device, which includes a main body shell 1, a material placement plate 2, a conveying roller 3, a loosening component 4, an adjustment component 5, an impurity chamber 6, a collecting box 7, a cotton condensing roller 8, a brushing roller 9, a discharge port 10 and a feeding channel 11, wherein:

[0041] Specifically in the embodiment of the present invention, the rotation of the loosening roller 41 drives the hemp fibers to rotate and move. When the hemp fibers rotate and move to the curved filter plate 42, the hemp fibers are pulled by the hemp fiber scraping teeth 43 to loosen the hemp fibers, and the impurities dropped by the hemp fibers are filtered out from the curved filter plate 42 and enter the interior of the impurity chamber 6, and then gathered into the interior of the collecting box 7; at the same time, the electric telescopic rod 54 is started, and the electric telescopic rod 54 drives the lifting grid frame 52 to move up and down reciprocatingly through the sliding bracket 51, and the lifting grid frame 52 intermittently lifts the hemp fibers on the inner side of the curved filter plate 42, so that the loosening roller 41 drives the hemp fibers to move to the feed channel 11, and the hemp fibers are transported to the cotton condensing roller 8.

[0042] like Figure 2 , Figure 4 and Figure 5 As shown, the material placement plate 2 is located at the top of the main shell 1 and is connected to the inside of the loosening component 4. The conveying roller 3 is meshed with the transmission gear to make the conveying roller 3 rotate synchronously. The conveying roller 3 is located between the material placement plate 2 and the loosening component 4 and is rotatably connected to the main shell 1. The loosening component 4 includes a loosening roller 41. A curved filter plate 42 is provided at the bottom of the loosening roller 41. A plurality of hemp fiber scraping teeth 43 are fixedly connected to the inner side of the curved filter plate 42 and the upper end of the loosening roller 41. A fiber shovel plate 44 is provided on the top of the loosening roller 41.

[0043] Specifically in the embodiment of the present invention, by providing a material placement plate 2, it is convenient to place the hemp fibers that need to be loosened. The conveying roller 3 provided in the middle of the loosening roller 41 and the material placement plate 2 is convenient for conveying the hemp fibers into the interior of the main shell 1. By providing a loosening component 4, the hemp fiber scraping teeth 43 on the surface of the loosening roller 41 drive the hemp fibers to move, and at the same time, the hemp fiber scraping teeth 43 inside the curved filter plate 42 pull the moving hemp fibers to loosen them, so that the hemp fibers are pulled loose, and at the same time, the impurities inside them will fall from the curved filter plate 42 into the impurity chamber 6, and then enter the interior of the collection box 7.

[0044] like Figure 2 , Figure 3 and Figure 6As shown, the loosening roller 41 is rotatably connected to the main shell 1, and one end of the loosening roller 41 penetrates the main shell 1 and is fixedly connected to the industrial motor, the curved filter plate 42 is fixedly connected to the main shell 1, the hemp fiber scraping teeth 43 on the surface of the loosening roller 41 are distributed in a ring shape, the hemp fiber scraping teeth 43 on the inner side of the curved filter plate 42 and the hemp fiber scraping teeth 43 on the surface of the loosening roller 41 are staggered, and the fiber shovel plate 44 is fixedly connected to the main shell 1, the fiber shovel plate 44 has an arc-shaped structure that bends downward toward the cotton condensing roller 8, the middle part of the fiber shovel plate 44 is linearly distributed with an opening corresponding to the position of the curved filter plate 42 on the surface of the loosening roller 41, and the bottom of the fiber shovel plate 44 is in conflict with the surface of the loosening roller 41.

[0045] Specifically in the embodiment of the present invention, a loosening roller 41 is provided, and the loosening roller 41 drives the hemp fiber scraping teeth 43 to rotate, so as to convey the hemp fibers. The hemp fiber scraping teeth 43 are arranged to be staggered between the surface of the loosening roller 41 and the inner side of the curved filter plate 42, so that when the loosening roller 41 drives the hemp fibers to rotate, the hemp fiber scraping teeth 43 will stagger with each other to pull the hemp fibers to loosen the hemp fibers. The setting change of the curved filter plate 42 will filter out impurities dropped from the hemp fibers when the hemp fibers are loosened. The fiber shovel plate 44 provided on the top of the loosening roller 41 can contact the surface of the loosening roller 41, so that the hemp fibers hung between the hemp fiber scraping teeth 43 on the surface of the loosening roller 41 can be scraped off by the fiber shovel plate 44, so as to avoid the hemp fibers from being entangled and accumulated on the surface of the loosening roller 41. The opening opened on the loosening roller 41 can avoid the hemp fiber scraping teeth 43 from being stuck with the loosening roller 41.

[0046] like Figures 3 to 6 As shown, the adjustment assembly 5 includes a pair of sliding brackets 51, a lifting grid frame 52 is movably connected in the middle of the pair of sliding brackets 51, springs 53 are fixedly connected on both sides of the lifting grid frame 52, an electric telescopic rod 54 is fixedly connected to the bottom of the sliding bracket 51, a sliding sealing baffle 55 is fixedly connected to the top of a sliding bracket 51, the sliding bracket 51 is slidably connected to the main body shell 1, the sliding bracket 51 is located on both sides of the curved filter plate 42, and sliding rods are linearly distributed in the middle of the sliding bracket 51, the lifting grid frame 52 is slidably connected to the curved filter plate 42, the lifting grid frame 52 includes two parts: fixed partitions on both sides and an arc-shaped grid plate in the middle, wherein the fixed partition is slidably connected to the sliding rod in the middle of the sliding bracket 51, the arc-shaped grid plate has the same shape and structure as the curved filter plate 42, and the arc-shaped grid plate is linearly distributed in the middle of the hemp fiber scraping teeth 43.

[0047] Therefore, by setting the adjustment component 5, the electric telescopic rod 54 drives the lifting grid frame 52 to move up and down, so that the lifting grid frame 52 lifts the hemp fibers inside the curved filter plate 42, and at the same time, the sliding sealing baffle 55 moves upward to release the separation of the feeding channel 11, so that the hemp fibers can be transported to the condensing roller 8. By setting the sliding bracket 51, the sliding bracket 51 drives the lifting grid frame 52 to move up and down, and the sliding rod set inside the sliding bracket 51 is convenient for limiting the lifting grid frame 52, so that the lifting grid frame 52 maintains stable movement. The setting of the lifting grid frame 52 is convenient for lifting the hemp fibers retained on the inner side of the curved filter plate 42. The grid plate of the lifting grid frame 52 lifts the hemp fibers on the inner side of the curved filter plate 42, so that the hemp fibers are disconnected from the hemp fiber scraping teeth 43 on the inner side of the curved filter plate 42, so that the pulling roller 41 can drive the hemp fibers to move and transport them to the inside of the feeding channel 11, and the lifting grid frame 52 is set to an arc shape similar to the curved filter plate 42, so that when the lifting grid frame 52 lifts the hemp fibers, the lifting grid frame 52 always seals the gaps between the curved filter plates 42.

[0048] like Figures 2 to 6 As shown, the lower end of the spring 53 is fixedly connected to the sliding bracket 51, and the spring 53 is sleeved on the outer side of the middle sliding rod of the sliding bracket 51, the bottom of the electric telescopic rod 54 penetrates the main body shell 1, and extends to the outside of the main body shell 1 and is fixedly connected to the main body shell 1, the sliding sealing baffle 55 is located at the top of the sliding bracket 51 close to the side of the cotton condensing roller 8, the sliding sealing baffle 55 is L-shaped and slidably connected to the inside of the feeding channel 11, the top of the sliding sealing baffle 55 penetrates the main body shell 1 and extends to the outside of the main body shell 1, the loosening roller 41 rotates to drive the fibers to move toward the feeding channel 11, the electric telescopic rod 54 drives the lifting grid frame 52 to move up and down, the lifting grid frame 52 lifts the hemp fibers on the inner side of the curved filter plate 42, and the sliding sealing baffle 55 moves upward, releasing the separation of the feeding channel 11, so that the loosening roller 41 drives the hemp fibers to move to the feeding channel 11, and the fiber shovel plate 44 scrapes the hemp fibers on the surface of the loosening roller 41.

[0049] Therefore, by setting the spring 53, after the lifting grid frame 52 rises to the top, the sliding bracket 51 can continue to move to push the sliding sealing baffle 55 to move upward, so as to release the separation of the feeding channel 11. The setting of the electric telescopic rod 54 is convenient for driving the sliding bracket 51 to move up and down. The sliding sealing baffle 55 arranged inside the feeding channel 11 can block the feeding channel 11 when the lifting grid frame 52 does not lift the hemp fibers inside the curved filter plate 42, so that the hemp fibers remain at the loosening roller 41, and prevent impurities from entering the feeding channel 11 to the condensing roller 8 when the hemp is pulled loose.

[0050] When the loosening roller 41 rotates and drives the fibers to move toward the feed channel 11, the electric telescopic rod 54 is started to drive the lifting grid frame 52 to move up and down, and the hemp fibers on the inner side of the curved filter plate 42 are intermittently lifted by the lifting grid frame 52, so that the hemp fibers will not remain on the inner side of the curved filter plate 42 and will not block the curved filter plate 42, thereby maintaining the filtering effect of the curved filter plate 42. At the same time, the sliding sealing baffle 55 moves upward to release the separation of the feed channel 11, so that the loosening roller 41 drives the hemp fibers to move to the feed channel 11, and transports the hemp fibers to the cotton condensing roller 8.

[0051] The embodiment of the present invention further provides a hemp fiber degumming treatment method, using the hemp fiber degumming treatment device described above, the treatment method comprises the steps of:

[0052] Step S 100 : Place the material on the top of the material placement plate 2, start the conveying roller 3, and the conveying roller 3 conveys the hemp fiber into the interior of the main shell 1;

[0053] Step S 200 : The loosening roller 41 rotates to drive the hemp fibers to rotate and move. When the hemp fibers move to the curved filter plate 42, the hemp fibers are pulled by the hemp fiber scraping teeth 43 to loosen the hemp fibers, and the impurities dropped by the hemp fibers are filtered out from the curved filter plate 42 into the impurity chamber 6, and then gathered into the collection box 7;

[0054] Step S 300 : Start the electric telescopic rod 54, which drives the lifting grid frame 52 to move up and down reciprocatingly through the sliding bracket 51, and the lifting grid frame 52 intermittently lifts the hemp fibers inside the curved filter plate 42, so that the hemp fibers will not remain inside the curved filter plate 42, ensuring the smooth flow of the curved filter plate 42;

[0055] Step S 400 The sliding sealing baffle 55 moves upward to release the separation of the feeding channel 11, so that the loosening roller 41 drives the flax fibers to move to the feeding channel 11, and transports the flax fibers to the condensing roller 8.
