Description

Technical Field

[0001] This application relates to the technical field of lyocell fiber production, and more particularly to a lyocell fiber raw material crushing device. Background Technology

[0002] Lyocell fiber, a high-performance regenerated cellulose fiber, is made from natural cellulose using advanced organic solvent spinning. It boasts advantages such as high strength, excellent moisture absorption and breathability, and good dyeing properties. 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 is of positive significance for environmental protection and sustainable development.

[0003] In the process of producing lyocell fiber from 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 or clumped. If they are not crushed, these waste fibers will encounter many problems in subsequent processes such as dissolving and spinning.

[0004] In related technologies, mechanical crushing is mainly used for crushing waste fiber materials. The most common equipment is the roller crusher, which uses two relatively rotating crushing rollers to squeeze and shear the waste fiber materials. Although this method can crush the fiber materials, there are certain drawbacks in the feeding method. This method usually uses a conveyor belt for feeding, which continuously transports the waste fiber materials between the two crushing rollers. However, during the conveying process, the waste fibers are prone to accumulate and entangle on the conveyor belt. When the material is conveyed to the feed inlet, a large amount of accumulated material will quickly block the crushing mechanism, causing the equipment to malfunction. This not only increases the maintenance cost of the equipment but also causes production interruptions. In addition, manual labor is required to continuously place the fiber materials on the conveyor belt, which is labor-intensive and inefficient. Summary of the Invention

[0005] This application aims to at least partially address one of the technical problems in the related art.

[0024] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0025] The following describes the lyocell fiber raw material crushing device according to an embodiment of this application with reference to the accompanying drawings.

[0026] The lyocell fiber raw material crushing device provided in this application embodiment can be applied in the production process of lyocell fiber raw materials to crush waste fiber raw materials. It can realize the intermittent automatic input of waste fiber raw materials, so as to effectively reduce the possibility of the crushing roller being blocked, and can also effectively reduce manual intervention, reduce labor intensity, and improve crushing efficiency.

[0027] like Figures 1-6 As shown, the lyocell fiber raw material crushing device of this application embodiment may include a housing 1, a partition 2, a crushing mechanism, a driving mechanism 4, a feeding assembly 5, and multiple unblocking mechanisms 6.

[0028] The partition 2 is fixedly installed inside the box 1. Multiple material discharge slots are provided on the partition 2. The top and bottom of the partition 2 are respectively set as the feeding area 101 and the crushing area 102. The crushing mechanism is rotatably installed inside the box 1 and is located in the crushing area 102.

[0029] The feeding assembly 5 may include a fixed rod 51, a rotating tube 52, multiple material picking mechanisms 53 and a material discharging mechanism 54.

[0030] The fixed rod 51 is fixedly installed inside the box 1 and is located between the partition 2 and the crushing mechanism. The rotating tube 52 is rotatably installed inside the box 1 and is sleeved on the fixed rod 51. Multiple material picking mechanisms 53 are respectively installed on the outer circumference of the rotating tube 52. The material discharging mechanism 54 is installed on the fixed rod 51 and is connected to the material discharging mechanism 54. The driving mechanism 4 is installed on the box 1 and is connected to the crushing mechanism and the rotating tube 52. Multiple unblocking mechanisms 6 are respectively installed on the partition 2 and are connected to the rotating tube 52.

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

[0032] Specifically, when crushing waste fiber raw materials, relevant personnel first put the waste fiber raw materials into the feeding area 101 through the feeding box door, and then start the drive mechanism 4 to drive the crushing mechanism to run. At the same time, the drive mechanism 4 also drives the rotating tube 52 to rotate, so that the rotating tube 52 drives multiple picking mechanisms 53 to rotate around the rotating tube 52 as the center. During the rotation of the picking mechanism 53, the picking mechanism 53 first hooks the waste fiber raw materials through the discharge channel on the partition plate 2. When the picking mechanism 53 conveys the hooked waste fiber raw materials to the bottom of the rotating tube 52, it cooperates with the discharge mechanism 54 to convey them into the crushing mechanism, and then the crushing mechanism crushes them. Finally, relevant personnel can take out the crushed fiber raw materials through the discharge box door. This can reduce the intermittent automatic feeding of waste fiber raw materials, effectively reduce the possibility of the crushing mechanism being blocked, and reduce the process of continuously placing waste fiber raw materials on the conveyor belt, reducing labor intensity and improving crushing efficiency.

[0033] In one embodiment of this application, such as Figures 1-6 As shown, the crushing mechanism may include two crushing rollers 3, the two ends of which are rotatably connected to the two inner side walls of the housing 1, and the two crushing rollers 3 are arranged side by side.

[0034] Specifically, relevant personnel drive the two crushing rollers 3 to move relative to each other through the drive mechanism 4, so as to crush the waste fiber raw material between the two crushing rollers 3 by squeezing and shearing.

[0035] In one embodiment of this application, such as Figures 1-6 As shown, the material handling mechanism 53 may include a fixed tube 531 and a gripping tube 532.

[0036] One end of the fixed tube 531 is fixedly disposed on the outer circumferential surface of the rotating tube 52, and the fixed tube 531 is connected to the interior of the rotating tube 52. One end of the gripping tube 532 is pivotally connected to the other end of the fixed tube 531, and the other end of the gripping tube 532 is set to a closed state.

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

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

[0039] The L-shaped airbag 541 is located inside the fixed tube 531 and the grasping tube 532, respectively, with both ends of the L-shaped airbag 541 fixedly connected to the inner walls of the fixed tube 531 and the grasping tube 532. The fixed cylinder 542 is fixedly installed inside the fixed tube 531, with one end of the fixed cylinder 542 communicating with the L-shaped airbag 541. The piston 543 is slidably installed inside the fixed cylinder 542, with the outer circumferential surface of the piston 543 adapted to the inner wall of the fixed cylinder 542. The cam roller 548 is sleeved on the fixed rod. On 51, the movable rod 544 is slidably disposed inside 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 rolledly connected to the outer peripheral surface of the cam roller 548 through a roller. The limiting plate 545 is fixedly disposed inside the fixed tube 531. The positioning plate 546 is sleeved on the movable rod 544. The first spring 547 is sleeved on the movable rod 544, and the two ends of the first spring 547 are fixedly connected to the limiting plate 545 and the positioning plate 546 respectively.

[0040] Specifically, while the rotating tube 52 rotates, it also drives the fixed tube 531 and the gripping tube 532 to rotate around the rotating tube 52 as the center. This causes the fixed tube 531 to drive the movable rod 544 to slide along the outer circumferential surface of the cam roller 548. Under the action of the first spring 547, the roller on the movable rod 544 remains in rolling contact with the outer circumferential surface of the cam roller 548, thus driving the movable rod 544 to slide back and forth. This, in turn, drives the piston 543 to reciprocate in and out of the L-shaped airbag 541. When the fixed tube 531 moves above the rotating tube 52, the L-shaped airbag 541 is inflated. The shape of the L-shaped airbag 541 causes the gripping tube 532 and the fixed tube 531 to form a certain angle, allowing the gripping tube to move more efficiently. The grabbing tube 532 cooperates with the fixed tube 531 to hook the waste fiber material in the feeding area 101 through the feeding channel on the partition plate 2. When the grabbing tube 532 carries the waste fiber material to the bottom of the rotating tube 52, the piston 543 draws the gas inside the L-shaped air bag 541, so that it cannot limit the angle of the grabbing tube 532. At this time, the waste fiber material will slide off the grabbing tube 532 under the action of gravity and fall between the two crushing rollers 3 for crushing. The crushing rollers 3 crush the waste fiber material. The above method realizes the automated intermittent feeding operation of waste fiber material, avoids the waste fiber material from clogging the crushing rollers 3, and eliminates the need for an additional conveyor belt to transport the waste fiber material, effectively reducing the equipment footprint and production cost.

[0041] In one embodiment of this application, such as Figures 1-6 As shown, the drive mechanism 4 may include a mounting bracket 401, a motor 402, two drive gears 403, a driven rod 404, a driven gear 405, and a chain 406.

[0042] The mounting bracket 401 is fixedly mounted on the housing 1, the motor 402 is mounted on the mounting bracket 401, and the output shaft of the motor 402 is coaxially connected to one end of one of the crushing rollers 3 through a coupling. Two drive gears 403 are respectively sleeved on the two crushing rollers 3 and are meshed together. One end of the driven rod 404 is rotatably connected to the housing 1, and the chain 406 is driven between the driven rod 404 and the rotating tube 52 through two sprockets. The driven gear 405 is sleeved on the driven rod 404 and is meshed with one of the drive gears 403.

[0043] Specifically, the relevant personnel start the motor 402 to drive one of the crushing rollers 3 to rotate, so that under the action of two meshing drive gears 403, the other crushing roller 3 is driven to move relative to it. Then, the waste fiber raw material between the two crushing rollers 3 is crushed by the squeezing and shearing forces. In addition, one of the drive gears 403 also drives the driven rod 404 to rotate through the driven gear 405 meshing with it. In turn, 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 one possible scenario, the drive gear 403 and driven gear 405 described in this embodiment can employ a commercially available gear transmission drive structure to adjust the rotation speed of the rotating tube 52 through the gear transmission drive structure.

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

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

[0047] Specifically, during the rotation of the rotating tube 52, the rotating tube 52 also drives the cam 604 to rotate, thereby enabling the cam 604 to reciprocate the lifting motion of the unblocking rod 601. This reciprocating lifting motion of the unblocking rod 601 improves the looseness of the waste fiber material, effectively avoiding the problem of accumulation and compression between waste fiber materials. Furthermore, this application achieves effective driving of the crushing mechanism, the material handling mechanism 53, and the unblocking mechanism 6 by a single motor 402, reducing the production cost of the equipment and the energy consumption during use.

[0048] In summary, the lyocell fiber raw material crushing device of this application embodiment can realize the intermittent automatic feeding of waste fiber raw materials, so as to effectively reduce the possibility of the crushing roller being blocked, and can also effectively reduce manual intervention, reduce labor intensity, and improve crushing efficiency.
