Description

Technical Field

[0002] Lyocell fiber, as a regenerated cellulose fiber with excellent performance, is based on natural cellulose and made through advanced organic solvent spinning method. It has the advantages of high strength, excellent moisture absorption and air permeability, and good dyeing performance. In the production of Lyocell fiber, recycled waste fibers are often used as an important source of raw materials. These waste fibers may come from waste materials and waste textiles in the textile production process. Reusing waste fibers can not only reduce production costs, but also reduce resource waste and promote the recycling of resources, which has positive significance for environmental protection and sustainable development.

[0003] In the process of producing Lyocell fiber using recycled waste fibers, crushing the raw materials is an essential pretreatment step. Waste fiber raw materials usually have irregular shapes and different sizes, and may be entangled, agglomerated, etc. If they are not crushed, these waste fibers will have many problems in subsequent dissolution, spinning and other processes.

[0004] In the related art, mechanical crushing means are mainly used for crushing fiber waste raw materials. A common equipment is a roller crusher, which uses two relatively rotating crushing rollers to squeeze and shear the waste fiber raw materials. Although this method can realize the crushing of fiber raw materials, the loading method has certain disadvantages. This method usually uses a conveyor belt for loading, and the conveyor belt is used to continuously transport the fiber waste raw materials to between the two crushing rollers. However, in the process of conveying it, the waste fibers are easily accumulated and entangled on the conveyor belt. When it is transported to the feed port, a large amount of accumulated raw materials will quickly block the crushing mechanism, causing the equipment to fail to work normally, which not only increases the maintenance cost of the equipment, but also causes interruptions in production time.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0025] The lyocell fiber raw material crushing device according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0031] It should be noted that the top and bottom of the box body 1 described in this embodiment are also respectively equipped with a feed box door (not specifically marked in the figure) and a discharge box door (not specifically marked in the figure), so as to facilitate the feeding of waste fiber raw materials into the loading area 101 and the discharge of crushed fiber raw materials from the crushing area 102.

[0032] Specifically, when the waste fiber raw materials are crushed, the relevant personnel first put the waste fiber raw materials into the loading area 101 through the feed box door, and then start the driving mechanism 4 to drive the crushing mechanism to operate. At the same time, the driving mechanism 4 also drives the rotating tube 52 to rotate, so that the rotating tube 52 drives multiple feeding mechanisms 53 to rotate with the rotating tube 52 as the center. During the rotation of the feeding mechanism 53, the feeding mechanism 53 first hooks the waste fiber raw materials through the unloading slot on the partition 2, and when the feeding mechanism 53 transports the hooked waste fiber raw materials to the bottom of the rotating tube 52, it cooperates with the discharge mechanism 54 to transport it to the crushing mechanism, and then the crushing mechanism crushes it.

[0037] It should be noted that a limit key (not specifically marked in the figure) is fixedly provided on the fixed tube 531 described in this embodiment, and the pivot angle of the grabbing tube 532 is limited by the limit key so that the pivot angle of the grabbing tube 532 is less than 90°.

[0038] In one embodiment of the present application, the discharge mechanism 54 may include an L-shaped airbag 541 , a fixed cylinder 542 , a piston 543 , a movable rod 544 , a limit plate 545 , a positioning plate 546 , a first spring 547 and a cam roller 548 .

[0039] The L-shaped airbag 541 is respectively located in the fixed tube 531 and the grabbing tube 532, and the two ends of the L-shaped airbag 541 are respectively fixedly connected to the inner walls of the fixed tube 531 and the grabbing tube 532. The fixed cylinder 542 is fixedly arranged in the fixed tube 531, and one end of the fixed cylinder 542 is connected to the L-shaped airbag 541. The piston 543 is slidably arranged in the fixed cylinder 542, and the outer peripheral surface of the piston 543 is adapted to the inner wall of the fixed cylinder 542. The cam roller 548 is sleeved on the fixed rod. 51, a movable rod 544 is slidably disposed in the fixed tube 531, one end of the movable rod 544 is fixedly connected to the piston 543, and the other end of the movable rod 544 is rollingly connected to the outer circumference of the cam roller 548 through a roller, a limit plate 545 is fixedly disposed in the fixed tube 531, a positioning plate 546 is sleeved on the movable rod 544, a first spring 547 is sleeved on the movable rod 544, and two ends of the first spring 547 are respectively fixedly connected to the limit plate 545 and the positioning plate 546.

[0040] Specifically, while the rotating tube 52 rotates, the rotating tube 52 also drives the fixed tube 531 and the grabbing tube 532 to rotate around the rotating tube 52 as the center, so as to drive the movable rod 544 to slide along the outer peripheral surface of the cam roller 548 through the fixed tube 531, and under the action of the first spring 547, the roller on the movable rod 544 can always be connected with the outer peripheral surface of the cam roller 548 in a rolling manner, so as to realize the reciprocating sliding drive of the movable rod 544, and then drive the piston 543 to reciprocate and pump the gas in the L-shaped airbag 541 through the movable rod 544. When the fixed tube 531 moves to the top of the rotating tube 52, the L-shaped airbag 541 is in an inflated state, so that a certain angle is formed between the grabbing tube 532 and the fixed tube 531 under the action of the shape of the L-shaped airbag 541, so as to The taking tube 532 cooperates with the fixed tube 531 to hook the waste fiber raw materials in the loading area 101 through the unloading groove on the partition 2, and when the grabbing tube 532 carries the waste fiber raw materials to the bottom of the rotating tube 52, the piston 543 extracts the gas inside the L-shaped airbag 541, making it impossible to limit the angle of the grabbing tube 532. At this time, the waste fiber raw materials will slide down the grabbing tube 532 under the action of gravity and fall between the two crushing rollers 3 to be crushed by the crushing roller 3. In this way, the automated intermittent feeding operation of the waste fiber raw materials is realized, the waste fiber raw materials are prevented from clogging the crushing roller 3, and there is no need to set up an additional conveyor belt to transport the waste fiber raw materials, which effectively reduces the equipment's footprint and production costs.

[0042] Among them, the mounting frame 401 is fixedly set on the box body 1, the motor 402 is set on the mounting frame 401, and the output shaft of the motor 402 is coaxially connected to one end of one of the crushing knife rollers 3 through a coupling, the two driving gears 403 are respectively sleeved on the two crushing knife rollers 3, and the two driving gears 403 are meshed and connected, one end of the driven rod 404 is rotatably connected to the box body 1, and the chain 406 is arranged between the driven rod 404 and the rotating tube 52 through two sprocket transmissions, the driven gear 405 is sleeved on the driven rod 404, and the driven gear 405 is meshed and connected with one of the driving gears 403.

[0043] Specifically, the relevant personnel drive one of the crushing knife rollers 3 to rotate by starting the motor 402, so as to drive the other crushing knife roller 3 to move relative to it under the action of two meshing driving gears 403, and then crush the waste fiber raw materials between the two crushing knife rollers 3 through the forces of extrusion and shearing, and one of the driving gears 403 also drives the driven rod 404 to rotate through the driven gear 405 meshing with it, so that the driven rod 404 drives the rotating tube 52 to rotate through the chain 406, so as to realize the linkage drive of the rotating tube 52.

[0044] As a possible situation, the driving gear 403 and the driven gear 405 described in this embodiment may use a gear speed change driving structure currently available on the market, so as to adjust the rotation speed of the rotating tube 52 through the gear speed change driving structure.

[0045] In one embodiment of the present application, Figure 1-Figure 6 As shown, the unblocking mechanism 6 may include a unblocking rod 601 , a movable plate 602 , a second spring 603 and a cam 604 .

[0046] Among them, the dredging rod 601 is slidably connected to the partition 2, the cam 604 is sleeved on the rotating tube 52, and one end of the dredging rod 601 is rollingly connected to the outer peripheral surface of the cam 604 through a roller, the movable plate 602 is sleeved on the dredging rod 601, the second spring 603 is sleeved on the dredging rod 601, and the two ends of the second spring 603 are respectively fixedly connected to the partition 2 and the movable plate 602.
