Description

Technical Field

[0001] The present application relates to the technical field of flax fiber processing, and in particular to an anti-blocking mechanism for a fiber dispersing machine. Background Art

[0002] At present, flax fiber is a rare natural fiber produced by processing flax. During the processing of flax fiber, it is necessary to use an opener to loosen the tightly connected flax to make the flax fiber reach a loose state for subsequent production and use.

[0003] In the related art, an opener is a process equipment that loosens compressed and entangled fiber raw materials and removes impurities. When in use, the staff needs to place the flax fibers on the conveyor belt of the opener, and the conveyor belt feeds the flax fibers into the opener for opening operations. In order to avoid affecting the opening effect by feeding too much material at one time, general openers usually install limiting guide rollers at the feed port to limit the feeding thickness of the material through the limiting guide rollers.

[0004] However, in actual use, since the flax fibers are initially relatively messy and tangled into balls, the flax fibers are easily piled up when feeding. In this way, when the thickness of the flax fibers is high, it is difficult for the limiting roller to continue feeding the flax fibers, and then the flax fiber balls will stay in front of the limiting roller, causing the limiting roller to be blocked, affecting the operation of the opener. At this time, the staff will manually pull the flax fiber balls back to pull the flax fiber balls apart. However, this will not only consume a lot of manpower, but also the limiting guide roller may cause the staff's hands to be caught in the equipment when pulling the flax fibers, which will pose a safety hazard and is very inconvenient.

[0005] In view of the above problems, an anti-blocking mechanism for a fiber dispersing machine is now designed. Utility Model Content

[0006] The embodiment of the present application provides an anti-blocking mechanism for a fiber unwinding machine to solve the problem in the related art that flax fibers are easily blocked at the limiting guide rollers during opening and feeding, and workers are required to manually pull and clean the flax fibers, which poses a safety hazard.

The two groups of rotating shafts are respectively arranged on the opposite sides of the two groups of support plates. The rotating shafts penetrate through the frame body and are rotatably connected thereto;

[0013] A driving assembly, which is arranged on the frame body and connected to the rotating shaft to drive the rotating shaft to rotate.

[0014] In some embodiments, the driving assembly includes a first pulley, a second pulley and a transmission belt. The first pulley is arranged on one of the rotating shafts. The second pulley is used to be mounted on the limiting guide roller. The transmission belt is sleeved on the first pulley and the second pulley.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Apparently, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application.

[0030] The embodiment of this application provides an anti-blocking mechanism for a fiber loosening machine, which can solve the problem in the related art that flax fibers are likely to be blocked at the limit guide rollers during the opening and feeding process, and it is also necessary for workers to manually pull and clean the flax fibers, which will pose a safety hazard.

[0031] Please refer to Figures 1 - 3 , an anti-blocking mechanism for a fiber loosening machine, which includes: a frame 1, a mounting frame 2, a fixed column 3, a connecting piece 4, a crankshaft 5, and a driving component 6. The frame 1 is used to be installed on the conveyor belt 100 of the opener. The mounting frame 2 is arranged on the frame 1. There are several groups of fixed columns 3, and all of the several fixed columns 3 are arranged at the lower end of the mounting frame 2. The two ends of the connecting piece 4 are respectively rotatably connected to the frame 1 and the mounting frame 2;

[0032] The crankshaft 5 is located above the connecting piece 4. The crankshaft 5 includes a fixed shaft 51, two groups of support plates 52, and two groups of rotating shafts 53. The fixed shaft 51 penetrates through the mounting frame 2 and is rotatably connected thereto. The two groups of support plates 52 are symmetrically arranged at both ends of the fixed shaft 51. The two groups of rotating shafts 53 are respectively arranged on the opposite sides of the two groups of support plates 52. The rotating shaft 53 penetrates through the frame 1 and is rotatably connected thereto. The driving component 6 is arranged on the frame 1 and is connected to the rotating shaft 53 to drive the rotating shaft 53 to rotate;

[0033] In this way, during use, the frame 1 can be installed on the conveyor belt 100 of the opener, and then the driving component 6 is used to drive the rotating shaft 53 to rotate, so that the rotating shaft 53 drives the fixed shaft 51 to rotate through the support plate 52. In this way, the fixed shaft 51 will drive the mounting frame 2 to move during the rotation process. At the same time, since the mounting frame 2 is movably connected to the frame 1 through the connecting piece 4, the mounting frame 2 will drive several fixed columns 3 to make a reciprocating circular curve motion when moving;

[0034] Please refer to Figures 4 - 5, so that when the flax fibers are stacked too thickly and block the limiting guide roller 200, the fixed shaft 51 rotates downward, which will push the mounting frame 2 downward. Thus, through the mounting frame 2, multiple fixed columns 3 are pushed downward, so that the fixed columns 3 are inserted into the flax fibers. Then, when the fixed shaft 51 continues to rotate downward, it will push the mounting frame 2 and multiple fixed columns 3 away from the limiting guide roller 200. Thus, through the multiple fixed columns 3, the flax fibers are pulled in a direction away from the limiting guide roller 200, so as to pull apart the stacked flax fibers and ensure the normal feeding of the flax fibers;

[0035] Then, when the fixed shaft 51 rotates upward, it will pull the mounting frame 2 upward and at the same time move the mounting frame 2 closer to the limiting guide roller 200. In this way, the fixed columns 3 can be driven by the mounting frame 2 to move away from the flax fibers, so that the fixed columns 3 are withdrawn from the flax fibers, avoiding the flax fibers being continuously wound around the fixed columns 3;

[0036] Then, after the fixed shaft 51 moves to the topmost position and then moves downward, it will continue to drive the fixed columns 3 to move downward to pick up the flax fibers and pull them apart. In this way, by repeating this cycle, the continuously moving fixed columns 3 can imitate the human hand to automatically pull apart the flax fibers stacked on the limiting guide roller 200. This can not only prevent the flax fibers from accumulating on the limiting guide roller 200 and affecting the opening efficiency of the flax fibers, but also does not require the staff to manually pull and clean the flax fibers. This can not only save a large amount of manpower, but also reduce the safety hazards, and has strong practicability.

[0037] Specifically, in this embodiment, the driving assembly 6 includes a first pulley 61, a second pulley 62 and a transmission belt 63. The first pulley 61 is arranged on one of the rotating shafts 53, the second pulley 62 is used to be installed on the limiting guide roller 200, and the transmission belt 63 is sleeved on the first pulley 61 and the second pulley 62;

[0038] In this way, when the flax fibers are opened by the opener, the rotation of the limiting guide roller 200 will drive the second pulley 62 to rotate. Thus, the second pulley 62 will drive the first pulley 61 to rotate through the transmission belt 63, and then drive the crankshaft 5 to rotate through the first pulley 61;

[0039] In this way, the device can be directly installed on the opener for operation without additionally installing a driving source. This can not only reduce the equipment cost, but also enhance the linkage effect between the device and the opener, so that the device and the opener cooperate more smoothly. Moreover, the device has a simple structure, is easy to maintain, and has strong practicability.

[0040] More specifically, a fixed rod 11 is provided on the frame body 1. The connecting member 4 includes two groups of connecting rods 41. The two groups of connecting rods 41 are symmetrically arranged on both sides of the mounting frame 2. One end of the connecting rod 41 is sleeved on the fixed rod 11 and rotatably connected thereto, and the end of the connecting rod 41 away from the fixed rod 11 is rotatably connected to the mounting frame 2;

[0041] By arranging the two groups of connecting rods 41 on both sides of the mounting frame 2 in this way, the forces on both sides of the mounting frame 2 can be made more uniform, avoiding excessive force on one side of the mounting frame 2 that may cause the equipment to jam or even be damaged, and ensuring the smoothness and service life of the device during operation.

[0042] Among them, several fixing columns 3 are equidistantly distributed on the mounting frame 2;

[0043] In this way, when multiple fixing columns 3 pull the flax fibers, the force on each fixing column 3 can be made more uniform, thus ensuring the service life of the fixing columns 3 and facilitating use.

[0044] Furthermore, in this embodiment, the mounting frame 2 includes a fixed frame 21 and a sleeve 22. The sleeve 22 is provided at the upper end of the fixed frame 21. The sleeve 22 is sleeved on the fixed shaft 51 and rotatably connected thereto. An empty slot 23 is provided on the fixed frame 21. The empty slot 23 is located below the sleeve 22. A plurality of through holes 24 are opened at the lower end of the empty slot 23, and a plurality of grooves 25 are opened at the upper end of the empty slot 23. The through holes 24 and the grooves 25 correspond to each other one by one. A plurality of fixing columns 3 penetrate through the through holes 24 and cooperate with the grooves 25;

[0045] Since the fixing column 3 will be subjected to a lateral thrust when pulling the flax fibers, by inserting the fixing column 3 into the fixed frame 21, the fixed frame 21 can reinforce the fixing column 3, avoiding the fixing column 3 being broken from the root due to excessive force at the lower end of the fixing column 3 through the lever principle when pulling the flax fibers. In this way, the service life and structural strength of the fixing column 3 can be enhanced, and the practicability is strong.

[0046] Preferably, a plurality of screws 26 are further provided on the mounting frame 2. The plurality of screws 26 correspond to the plurality of grooves 25 one by one. The screws 26 penetrate through the fixed frame 21 and are threadedly connected to the top end of the fixing column 3;

[0047] When the fixing column 3 needs to be replaced after long-term use, the staff can rotate the screw 26 to separate the screw 26 from the fixing column 3, then pull out the damaged fixing column 3 from the fixing bracket 21, and then insert the new fixing column 3 through the through hole 24 into the groove 25. Then the staff screws the screw 26 again, so that the fixing column 3 can be fixed on the fixing bracket 21 through the threaded connection between the screw 26 and the fixing column 3. This facilitates the disassembly, installation and replacement of the fixing column 3 and makes it convenient to use.
