Description

Technical Field

[0001] The utility model relates to the technical field of cotton pulp board production, in particular to a device for screening and removing impurities from production materials. Background Art

[0002] Cotton pulp board is a kind of pulp, which is made of waste cotton and cotton linters from the textile industry by caustic soda method. It contains pure cellulose, and the fibers are slender and elastic, tough and fold-resistant, and have good absorbency. The paper made from it is fine and soft, highly opaque, and can be preserved for a long time. The bleached ones are used to make filter paper, absorbent base paper, drawing paper, bond paper and other high-grade printing papers, and the unbleached ones are used to make steel paper base paper, etc. It is sometimes also used as a raw material for rayon and cellulose acetate derivatives. In the process of making cotton pulp board, it is necessary to screen the waste cotton and cotton linters in advance to remove dust and impurities in the raw materials. However, the current production material impurity removal device has a poor screening effect on the dust and impurities of the raw materials, resulting in more impurities in the final produced cotton pulp board. Secondly, the screen of the current dust screening device is easily blocked by dust and impurities, and the screen needs to be manually cleaned, which ultimately leads to the problem of low efficiency of the impurity removal device. Therefore, a production material impurity screening and removal device is proposed to address the above problems. Utility Model Content

[0019] A device for screening and removing impurities from production materials comprises a workbench 1 and a screen 7. A support plate 2 is fixedly connected to the left and right sides of the top of the workbench 1. The upper and lower ends of the inner side of the support plate 2 are fixedly connected to a first spring 3. A slider 4 is fixedly connected between the first springs 3 at the upper and lower ends. The slider 4 is slidably connected to the support plate 2. The outer side of the right end of the slider 4 at the right end is fixedly connected to a motor 5. The left end of the main shaft of the motor 5 is fixedly connected to a rotating shaft 6. The outer sides of the left and right ends of the rotating shaft 6 are fixedly connected to a screen 7. A movable door 8 is arranged at the bottom end of the screen 7. A weight-increasing block 9 is fixedly connected to the outer side of the central position of the rotating shaft 6. This arrangement can drive the rotation of the screen 7 and make the screen 7 vibrate, so as to effectively screen dust and impurities. The rotating shaft 6 runs through the slider 4 at the left end. A fixed block 10 is fixedly connected to the outer side of the left end of the rotating shaft 6. The rotating shaft 6 is rotatably connected to the slider 4. This arrangement can make the rotating shaft 6 move in the sliding The block 4 rotates internally, and there are four first springs 3 in total. The first springs 3 are symmetrically distributed on the inner sides of the left and right support plates 2 at both ends. Through this arrangement, the screen 7 can be stably supported. A dust collecting box 11 is provided on the top of the workbench 1, and a cleaning brush 12 is provided on the top of the screen 7. The left and right outer sides of the cleaning brush 12 are fixedly connected with connecting plates 13. Through this arrangement, the cleaning brush 12 can clean the dust and impurities on the outside of the screen 7, thereby preventing the screen 7 from being blocked. A positioning block 14 is fixedly connected to the bottom end of the connecting plate 13, and a bayonet 15 is engaged with the inner side of the positioning block 14. A connecting rod 16 is fixedly connected to the outer side of the other end of the bayonet 15. The connecting rod 16 is slidably connected to the support plate 2, and the outer side of the connecting rod 16 is covered with a second spring 17. The spring 17 is fixedly connected to the bayonet 15 and the support plate 2. Through this arrangement, it is convenient to disassemble and clean the cleaning brush 12.

[0020] Working process: Before use, the utility model is powered by an external power supply. When the raw materials for the production of cotton pulp boards need to be screened, the raw materials are first placed into the screen 7 through the movable door 8, and then the movable door 8 is closed and the motor 5 is started. The motor 5 drives the rotating shaft 6 and the weight-increasing block 9 to rotate inside the slider 4. When the weight-increasing block 9 rotates to the bottom, the slider 4 outside the rotating shaft 6 is driven to move downward due to the gravity of the weight-increasing block 9. At this time, the first spring 3 at the top end of the support plate 2 is stretched, and the first spring 3 at the bottom end of the support block 2 is compressed. Then, the slider 4 is driven upward through the first springs 3 at the upper and lower ends in the process of continuous deformation and recovery of the deformation. The cleaning brush 12 can be used to clean the dust and impurities on the outside of the screen 7 to prevent the screen 7 from being blocked. At the same time, the connecting rod 16 can be pulled to drive the latch 15 to compress the second spring 17. At this time, the first connecting rod 16 slides inside the support plate 2 until the latch 15 is disengaged from the positioning block 14. At this time, the cleaning brush 12 and the connecting plate 13 can be removed, which facilitates the disassembly and cleaning of the cleaning brush 12.
