Description

Technical Field

[0001] The utility model belongs to the technical field of cellulose ether raw material crushing, in particular to a refined cotton crusher. Background Art

[0002] Cellulose ether is a kind of macromolecular compound obtained by replacing part or all of the hydroxyl groups on the cellulose molecular chain with hydrocarbon groups through etherification reaction of natural cellulose. Refined cotton is a raw material source of cellulose. It is a high-purity cellulose product obtained by treating cotton fibers with special processes. At present, the processing of refined cotton, the raw material of cellulose ether, is mainly carried out by using a special refined cotton pulverizer.

[0003] The authorization announcement is CN 220678067 U, a refined cotton pulverizing mechanism for cotton cellulose production, including a base, a pulverizing mechanism and a dust removal mechanism, support rods are fixedly installed around the top of the base, a pulverizing box is fixedly installed on the top of the support rods, and a fixed box is fixedly installed on the left side of the pulverizing box; the pulverizing mechanism includes a rotating shaft movably installed at the top and bottom of the pulverizing box, and pulverizing blades are fixedly installed around the outer surface of the rotating shaft. The refined cotton pulverizing mechanism for cotton cellulose production, by setting up a pulverizing mechanism, a servo motor can drive the pulverizing blades to rotate via a rotating shaft and a transmission belt, and because the upper and lower groups of pulverizing blades are cross-displaced, the pulverization of refined cotton can be completed efficiently and comprehensively, and the pulverized refined cotton will enter the conveying pipe, and by setting up a dust removal mechanism, the dust suction fan can suck the dust and debris in the refined cotton into the slag storage box for storage;

[0004] Although dust can be cleaned during refined cotton processing, there are still some problems in daily use. When refined cotton is processed, cohesion is easily formed between the cotton fibers, which causes the originally loose cotton fibers to clump together, making the cotton material present a significant lump-like structure. Moreover, the fibers inside these clumps are closely arranged and intertwined with each other, which greatly weakens the looseness and fluidity of the overall material. This leads to a significant reduction in the efficiency of the subsequent refined cotton crushing process. Faced with large-area, high-density cotton clumps, the crushing tool needs to consume more energy to penetrate and disperse these clumps, resulting in a decrease in the total amount of fiber processed per unit time and a significant reduction in the crushing efficiency. Utility Model Content

[0005] In view of this, the utility model provides a refined cotton pulverizer, which can comb and loosen the refined cotton through a cotton loosening mechanism, so that the sticky parts between the cotton fibers can be separated, ensuring that the cotton balls are fully loosened, improving the looseness and fluidity of the refined cotton, thereby improving the subsequent refined cotton pulverization efficiency.

[0006] In order to solve the above technical problems, the utility model provides a refined cotton pulverizer, including a pulverizing box and a cotton loosening mechanism arranged at the upper end of the pulverizing box, the cotton loosening mechanism includes a rotating roller which is laterally symmetrically rotated and connected to the upper end between the front and rear walls of the pulverizing box, the outer arc surfaces of the rotating rollers are provided with longitudinally uniformly distributed cotton loosening tooth rings, the cotton loosening tooth rings on the two rotating rollers are arranged at intervals, the left and right ends of the top wall of the pulverizing box are provided with laterally symmetrically distributed material guide plates near the feed port, and the bottom wall of the pulverizing box is also provided with a pulverizing assembly.

[0007] The cotton loosening mechanism also includes scrapers respectively arranged at the lower ends of the inner inclined surfaces of the material guide plates, and the scrapers are respectively arranged in cooperation with the cotton loosening gear rings that are longitudinally adjacent to each other on the same side; the cotton loosening mechanism also includes gears respectively arranged at the front extension ends of the rotating rollers, and the two gears are meshed and connected with each other; the cotton loosening mechanism also includes motor 1 arranged at the upper right end of the rear surface of the crushing box, the front end of the output shaft of motor 1 is fixedly connected to the rear extension end of the rotating roller on the right side, and motor 1 is electrically connected to an external single-chip computer.

[0008] The crushing assembly includes a rotating rod that is laterally symmetrically connected to the bottom wall of the crushing box. The outer arc surface of the rotating rod is provided with vertically evenly distributed crushing tool holders. The crushing tool holders on the two rotating rods are arranged at intervals. The lower end of the crushing box is also provided with a driving assembly for driving the rotating rod to rotate.

[0009] The driving assembly includes an installation cavity arranged in the middle of the lower end of the crushing box, a transmission rod is rotatably connected between the left and right walls of the installation cavity, a bevel gear 1 is provided at the right end of the outer arc surface of the transmission rod and is symmetrically distributed laterally, the lower ends of the rotating rods pass through the through holes correspondingly arranged on the top wall surface of the installation cavity and extend into the installation cavity, and bevel gear 2 is provided at the lower ends of the rotating rods, and bevel gear 2 is respectively meshed and connected with the adjacent bevel gear 1 on the same side; the driving assembly also includes motor 2 arranged at the lower end of the left surface of the crushing box, the right end of the output shaft of motor 2 is fixedly connected to the left extension end of the rotating rod, and motor 2 is electrically connected to the external single-chip computer.

[0010] The beneficial effects of the above technical solution of the utility model are as follows:

[0011] 1. First, the relevant staff controls the synchronous operation of motor 1 and motor 2 through an external single-chip microcomputer, and then the relevant staff feeds the raw material refined cotton required for the production of cellulose ether into the crushing box. The refined cotton entering the crushing box is guided to between the two rotating rollers through the guide plate. At this time, the output shaft of motor 1 rotates to drive the rotating roller on the right to rotate synchronously. Since the gears on the two rotating rollers are engaged with each other, the rotation of the rotating roller on the right will synchronously drive the rotating roller on the left to rotate in the opposite direction. When the two rotating rollers rotate in the opposite directions with the same amplitude at the same time, the loose cotton tooth rings arranged at intervals on them also rotate synchronously, thereby combing and loosening the refined cotton, separating the adhesion parts between the cotton fibers, ensuring that the cotton balls are fully loosened, improving the looseness and fluidity of the refined cotton, and thus improving the subsequent refined cotton crushing efficiency.

[0012] 2. The refined cotton processed by the cotton loosening mechanism falls into the bottom of the crushing box. At this time, the output shaft of the second motor rotates to drive the rotating rod and the second bevel gear to rotate synchronously. When the second bevel gear rotates, it drives the corresponding transmission rod and the crushing knife frame to rotate synchronously in the opposite direction through the corresponding bevel gear one that is meshed with it, so as to crush the loosened refined cotton, which greatly improves the crushing effect of the refined cotton. The crushed cotton fibers are discharged through the discharge port at the bottom of the crushing box to complete the entire crushing operation. The cotton balls are first combed and loosened by the cotton loosening mechanism, and then crushed efficiently by the crushing component. The two work together to ensure that the refined cotton obtains a uniform and appropriately fine crushed product after the cotton loosening and crushing processes.

[0013] 3. The scraper cooperates with the loose cotton tooth ring to avoid blockage or accumulation on the loose cotton tooth ring. BRIEF DESCRIPTION OF THE DRAWINGS
