Background technology
The general timber that adopts is as main raw material in the paper industry, but be accompanied by the further deterioration of environment, this employing log is just progressively replaced as the technology of raw material, in order to guarantee the needs of paper industry to the full extent, engendered now and adopted the hair grass, cotton stalk, reed, corn stalk, careless class such as straw is as the technology of pulping raw material, not only provide new fiber source for paper industry, and realized the utilization of refuse, changed the situation that original above-mentioned material can only burn or go back the field, realize the comprehensive utilization of resource, had splendid society and economic benefit.
At paper industry, particularly can make things convenient for the pulping of raw material for convenience, above-mentioned raw material need carry out pulverization process earlier before production, existing chaffcutter generally adopts traditional shearing mechanism, needs kinetic energy big, causes the energy consumption height, the cutting blade abrasion frequency is big, has improved labor strength.Generally speaking the main now roller-type hay cutter that adopts, the main chaffcutter operating part of this chaffcutter is the cast iron roll about diameter 400mm, on stud with 3 to 4 blades, in rotary course, form shearing force cut-out wheat straw by huge kinetic energy and the stationary knife on the main frame, this structure not only bring electric energy a large amount of consumption most criticals be the length of uncontrollable wheat straw section, reason is that the rotating speed of action roller is certain, so the breaks in the certain hour are certain, but present wheat straw is machine substantially receives, the approach axis of wheat straw is disorderly and unsystematic, can't guarantee the even discharging of wheat straw.
Summary of the invention
At many weak points that prior art exists, the utility model provides a kind of equipment that the raw material of paper grade (stock) is pulverized, and mainly comprises Moving plate and price fixing, all has bar-shaped cutting knife on Moving plate and the price fixing, at the poroid sieve plate of the outside coating of two dishes.This grass chopper compares with traditional chaffcutter that to have the specific yield energy consumption low, single device output is big, and feeding is simple, realizes advantages such as automation feeding easily, and this equipment is applied widely, and careless class pulping raw materials such as hair grass, cotton stalk, reed, corn stalk, straw all can be suitable for to be pulverized.
The concrete technical scheme that the utility model adopted is: a kind of paper grade (stock) raw material pulverizing machine, comprise front housing and back cabinet, the discharging opening of flexible connection and run through the main shaft of back cabinet, front housing is provided with the price fixing of fixedlying connected with front housing, back cabinet is provided with main shaft fixedlys connected, and Moving plate with the main shaft rotation, be provided with cutting knife on price fixing and the Moving plate, front housing and back cabinet inboard are provided with screen cloth.
After adopting this design, the raw material wheat straw is admitted in the housing by the charging aperture that is arranged on the front housing, open the motor that is connected with main shaft of peripheral hardware this moment, making it drive main shaft rotates, thereby realize the rotation of Moving plate, owing to be provided with cutting knife on the Moving plate and on the price fixing, when Moving plate rotates, the raw material that exists between the cutting knife that rotates and the cutting knife of fixing will be cut off, thereby realized the cut-out of raw material, be cut into suitable size, also be provided with screen cloth in the casing inboard in order to guarantee material, can come the raw material after handling is screened by screen cloth like this, the raw material that only meets the sieve aperture requirement just can pass through sieve aperture, discharges from discharging opening afterwards, and underproof raw material then can continue to be cut off in casing, the requirement that meets sieve aperture up to its length just can be discharged from, and has so just realized the uniformity coefficient of getting the raw materials ready.
Cutting knife on the Moving plate is short round steel, cutting knife on the price fixing is short square steel, cutting knife on the Moving plate and the cutting knife on the price fixing are crisscross arranged, can all have different materials like this and cut off the effect of pulverizing, and guaranteed that the cutting knife on the Moving plate can not collide with the cutting knife on the Moving plate in the Moving plate rotation process, prevented the damage of equipment; What the screen cloth that is adopted was generally selected for use is netted cylinder, and be embedded into casing inside by one groove that respectively has on the casing of front and back, thereby realize the detection and the screening of the degree of cutting off for raw material, in the groove that only needs during installation its reeve back cabinet is got, when front housing is closed, just in time tighten screen cloth, raw material such as wheat straw enters inside by charging aperture like this, be equivalent to be closed, to a certain degree discharge by sieve aperture up to broken arriving by screen cloth.
In slurrying industry the inside, the major parameter of getting the raw materials ready is exactly the length of tablet, in the ordinary course of things, this length is 2-4cm, long, too short all not too suitable, so the size of sieve aperture sees that according to the situation that we use diameter 3-6cm is proper, can satisfy the requirement of getting the raw materials ready of various differences substantially.
In order often to open the front and back casing of this raw material pulverizing machine, conveniently its inside is cleared up and keeped in repair, back cabinet and front housing are provided with jockey, and what generally adopt is the form of rotating shaft, and, also be provided with locking mechanism on the casing of front and back for the safety in the use.
Use for convenience and install, this pulverizer of casing is arranged on the frame before and after generally will comprising, and frame is provided with the motor that is connected with main shaft as its power set.
In sum, after adopting the pulverizer of said structure, it is low to have the specific yield energy consumption, single device output is big, feeding is simple, realize advantages such as automation feeding easily, and this equipment is applied widely, careless class pulping raw materials such as hair grass, cotton stalk, reed, corn stalk, straw all can be suitable for to be pulverized.
