Description

Technical Field

[0001] This utility model relates to the field of refined cotton production, and in particular to the technical field of a refined cotton opening device. Background Technology

[0002] Refined cotton is a high-purity cellulose product obtained by refining cotton linters through alkaline cooking, bleaching, and other processes. The main material of refined cotton is baled cotton linters. During production, the baled cotton linters need to be evenly opened. This opening process removes impurities and prepares the cotton for subsequent even alkali impregnation. Currently used cotton opening devices require manual tearing of the cotton linters into sheets of a specified thickness before using a licker-in roller to break up the sheets. This method is inefficient, and the open-type opening system causes cotton dust to leak out, impacting the environment. Utility Model Content

[0018] Example 1 Figure 1As shown in Figure 3, the cotton lint opening device for refined cotton includes a housing 1, a first pair of rollers 2, a first motor 3, a second pair of rollers 4, a second motor 5, a third pair of rollers 6, a third motor 7, a guide plate 8, a support screw 9, a roller shutter 10, a roller shutter shaft, a traction rope 11, a roller shutter motor 12, a counterweight 13, and a discharge pipe 14. The upper end of the housing 1 is open. A through groove 15 is formed on the left side wall of the upper opening of the housing 1, and a pair of through holes 16 corresponding to the through groove 15 are formed on the right side wall of the upper opening of the housing 1. Sliding grooves 17 are formed on the front and rear side walls of the upper opening of the housing 1, respectively, and the sliding grooves 17 correspond to the through grooves 15. The roller shutter shaft is rotatably mounted on the outside of the left side wall of the housing 1. The roller shutter 10 is slidably placed in the sliding grooves 17 on the front and rear side walls of the housing 1 through the front and rear sides. One end of the roller blind 10 passes through the through groove 15 and is wound around the roller blind shaft. One end of the pair of traction ropes 11 passes through the through hole 16 on the right side wall of the housing 1 and is fixedly connected to the other end of the roller blind 10. The other end of the pair of traction ropes 11 is fixedly connected to the pair of counterweights 13. The roller blind motor 12 is fixedly installed outside the housing 1. The output shaft of the roller blind motor 12 is connected to the roller blind shaft for transmission. When material needs to be fed, the roller blind motor 12 drives the roller blind shaft to rotate, and the roller blind shaft winds the roller blind, opening the upper opening of the housing 1 to facilitate material feeding. After the material feeding is completed, the roller blind motor 12 drives the roller blind shaft to rotate in the opposite direction. At the same time, under the action of the counterweight 13, the roller blind 10 unfolds, closing the upper opening of the housing 1 to prevent cotton dust from leaking out of the upper opening when opening the cotton, thus protecting the working environment.The first pair of rollers 2, the second pair of rollers 4, and the third pair of rollers 6 are rotatably mounted inside the housing 1. The second pair of rollers 4 and the third pair of rollers 6 are located below the first pair of rollers 2. The second pair of rollers 4 and the third pair of rollers 6 can perform a second opening process on the material after it has been opened by the first pair of rollers 2, thereby improving the opening effect. The first pair of rollers 2, the second pair of rollers 4, and the third pair of rollers 6 are each meshed with a gear at their ends, that is, the rollers are connected to each other by gear meshing at their ends. The first motor 3, the second motor 5, and the third motor 7 are fixedly mounted outside the housing 1. The output shafts of the first motor 3, the second motor 5, and the third motor 7 are respectively connected to any input shaft of the first pair of rollers 2, the second pair of rollers 4, and the third pair of rollers 6, that is, the three motors drive the three rollers to rotate. The first pair of rollers 2, the second pair of rollers 4, and the third pair of rollers 6 are each provided with an "L"-shaped tearing claw 18. The "L"-shaped tearing claws 18 on each pair of rollers are arranged facing away from each other. On both sides of the roller 6, there are mesh plates 19 that cooperate with the tearing claws 18. The mesh plates 19 are fixedly installed inside the housing 1. The mesh plates 19 improve the cotton opening effect and also have a dirt removal function. The paired guide plates 8 are respectively hinged at one end to the left and right side walls inside the housing 1. The other end of the paired guide plates 8 corresponds to the first roller 2. Support holes are also opened on the left and right side walls of the housing 1. Screw sleeve seats 20 are movably installed in the support holes. The support screw 9 is threadedly installed in the screw sleeve seat 20. The upper end of the support screw 9 is movably hinged to the bottom of the guide plate 8. A handwheel 22 is fixedly installed at the lower end of the support screw 9. By rotating the handwheel 22, the support screw 9 is rotated within the screw sleeve seat 20, thereby changing the tilt angle of the guide plate 8, which is beneficial for limiting the cotton bales during opening. The lower end of the housing 1 is provided with a discharge port, and the discharge pipe 14 is connected to the housing 1 through the discharge port. The material after opening is discharged from the discharge pipe 14. In order to improve the flexibility of the traction rope 11, a pair of guide pulleys 21 are installed on the outside of the right side wall of the housing 1, and the traction rope 11 is wound around the guide pulleys 21.
