The applicant has found that refined cotton is primarily a compressed mass of cotton which, after being broken by the plucker, forms a cotton flock having a soft texture which is fed from the top of the apparatus by belt transport, the feed rate being adjustable by the plucker. The cotton pulp is a paper-shaped cotton pulp paperboard, and the texture is hard, and no proper position is arranged at the top of the device for feeding paper. Therefore, the cotton pulp is pulled into the equipment by utilizing the two conveying rollers, the feeding amount of the cotton pulp can be controlled by adjusting the rotating speed of the conveying rollers to control the speed of the stretched paperboard, and the feeding amount is controlled.
In specific implementation, the cotton pulp is in a roll shape with the width of about 760mm and the thickness of 2.5mm-3.5mm, and the width of the crusher is 1000 mm. The width of the crusher can meet the required width for crushing cotton pulp. The local structure of the crusher is shown in figure 1, the upper pressing strip 1 and the lower pressing strip 2 are tightly closed together by using a closing nut, the gap A between the upper pressing strip 1 and the lower pressing strip 2 is very small and about 1mm in a closed state, when equipment is overhauled, the closing nut of the equipment is detached, and the parts above the lower pressing strip 2 are shaken up by using a hydraulic rocker arm.
According to the structural characteristics of equipment and the demand of the improvement of a grinder, the equipment is improved by adjusting the gap A between the upper pressing strip 1 and the lower pressing strip 2, the improved upper pressing strip 1 is shown in figure 3, the distance between the crushing port 5 and the lower pressing strip 2 is about 14mm, the distance between the feeding port 4 and the lower pressing strip 2 is about 28mm, and the distance between the feeding port 4 and the lower pressing strip 2 is about 28mm, so that a larger gap is ensured during paper feeding, the paper feeding is facilitated, the distance between the blade and the lower pressing strip is reduced, and the leakage of cotton powder during the crushing is reduced.
As shown in figure 1, two conveying rollers are added in front of a cotton pulp feeding port 4 for conveying cotton pulp into a pulverizer. When viewed from the paper feeding direction, the upper conveying roller 6 and the lower conveying roller 7 are arranged in front of the upper pressing strip 1 and the lower pressing strip 2, and the upper and lower positions of the upper conveying roller 6 and the lower conveying roller 7 are adjusted to ensure that the cotton pulp is aligned with the feeding opening 4 when being conveyed.
The feeding system of the pulverizer provided by the invention realizes the pulverizing function of two raw materials of purified cotton and cotton pulp. Cotton pulp can get into the rubbing crusher through the feed inlet in, and the paper feed process is steady, and the no card paper phenomenon, the leakage quantity of cotton powder is a little, satisfies crushing demand. Moreover, the production cost of the product is reduced after the cotton powder is obtained by using the cotton pulp.
