Description

Technical Field

[0002] An opener is an indispensable device in the textile industry, mainly used to loosen the compacted and entangled fiber raw materials and efficiently remove the impurities mixed therein. Its core function is to loosen the large entangled fibers into small pieces or bundles, while realizing the mixing of fibers and the removal of impurities.

[0003] The core working part of the opener is the cylinder roller. Cooperating with the working rollers distributed around its outer side, the chemical fiber raw materials are conveyed along with the cylinder roller, making them move along the outer surface of the cylinder roller. At the same time, the spikes on the cylinder roller tear and disperse the chemical fiber raw materials to make them fluffy, so as to achieve the opening effect.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention;

[0026] Please refer to Figures 1-6 , in the present invention, a chemical fiber raw material opener for rotor spinning processing includes a base 1. Both ends of the top of the base 1 are provided with conveyor belts 2. Two side positioning plates 3 are fixedly installed on the base 1. Two groups of symmetrically distributed working rollers 4 are installed between the two side positioning plates 3. A cylinder roller 5 is installed between the two side positioning plates 3. The cylinder roller 5 is hollow. A driving mechanism 6 is installed between the two side positioning plates 3. One end of the driving mechanism 6 penetrates through the cylinder roller 5 and is connected and matched with it. The driving mechanism 6 is connected and matched with the two groups of working rollers 4. A fan blade 7 is installed inside one end of the back surface of the cylinder roller 5. Two housings 8 are slidably installed on the base 1. The two housings 8 are relatively matched and clamped on the outside of the two side positioning plates 3. Two locking mechanisms 9 are installed on the outside between the two housings 8. A negative pressure dust removal mechanism 10 is installed on the right housing 8. A through slot 11 is opened on the base 1. The outside of the cylinder roller 5 extends into the inside of the through slot 11. An opening and closing mechanism 12 is installed at the bottom of the base 1. An annular hole group 13 arranged at equal distances is opened on the outside of the cylinder roller 5. A rake bar 15 is fixedly connected between the two side positioning plates 3. The teeth of the rake bar 15 fit into the angular teeth gaps of the cylinder roller 5. The other side of the rake bar 15 slopes downward above the conveyor belt 2 on the right.

[0027] In the present invention, with the base 1 as the device support, first, when in use, start the driving mechanism 6 to drive the cylinder roller 5 and the working rollers 4 on both sides to rotate. Then, put the chemical fiber raw materials through the conveyor belt 2 on the left for feeding. The chemical fiber raw materials enter the inside of the housing 8, are rotated and torn and dispersed upward by the rotating cylinder roller 5 in cooperation with the working roller 4 on the left. Then, the chemical fiber raw materials pass through the highest point of the cylinder roller 5 and enter the conveying area of the working roller 4 on the right. They move downward in cooperation with the cylinder roller 5 and are guided by the rake bar 15 onto the conveyor belt 2 on the right for discharging, completing the opening operation;

[0028] During the opening operation, the negative pressure dust removal mechanism 10 is started to adsorb the torn chemical fiber raw materials from the upper shell 8 of the highest point of the cylinder roller 5, adsorb and clean the dust, effectively avoiding the dispersion of scattered chemical fiber fibers and dust;

[0029] At the same time, while the driving mechanism 6 drives the cylinder roller 5 to rotate, it will drive the fan blade 7 to rotate synchronously. The rotation of the fan blade 7 introduces low-pressure air flow from the back end of the cylinder roller 5, enters the inside of the cylinder roller 5, and increases the internal pressure. The pressurized air flow blows the opened chemical fiber raw materials outward along the annular hole group 13, making the opening and dust removal effects better. Combining with the adsorption effect of the negative pressure dust removal mechanism 10, it realizes efficient cleaning and dust removal, and also uses the blowing negative pressure effect to reduce the residue of the opened chemical fiber raw materials on the cylinder roller 5;

[0030] When the cylinder roller 5 needs to be cleaned, only need to pull the opening and closing mechanism 12 at the bottom to open, so that the through groove 11 is exposed. At this time, the part of the cylinder roller 5 located inside the through groove 11 is exposed, which is convenient for cleaning its surface. And during cleaning, it is convenient to adjust the rotation angle of the cylinder roller 5 to achieve comprehensive cleaning of its surface. Thus, when the device is cleaning the surface of the cylinder, it does not need to be disassembled a lot, and the operation is more convenient and efficient. At the same time, when the equipment is flowing, the continuous air flow blows the chemical fiber raw materials and cooperates with the adsorption to clean the dust, the cleaning effect is better and more thorough, and it also helps to reduce the residue of the opened chemical fiber raw materials and extend the operation cycle of the equipment, solving the problem that in the prior art, during the operation of the opener, with the running time, the surface of the cylinder will continuously remain chemical fiber raw material filaments and need to be cleaned regularly. However, the current cleaning method requires disassembling the equipment to completely expose the cylinder or directly removing the cylinder, with low operation efficiency, long time consumption and difficult operation. And when the cylinder is running, the dust in the raw materials will be scattered and cleaned, but some small particle dust will still adhere to the surface of the scattered chemical fiber raw materials, and the cleaning effect is not good.

[0032] In the present invention, the two end chucks 121 cooperate with the two rows of L-shaped chucks 122 to support the moving plate 123, so that it slides left and right along the bottom of the base 1, realizing the closing and opening of the through groove 11, facilitating the cleaning operation and the closing after the operation.
