Abstract

The utility model discloses an integrated tool holder for a first pulverizer, which is a rotor of the first pulverizer used for processing PVA (polyvinyl alcohol in the vinylon industry) and cuts bulk materials into strips. The prior structure is to assemble the entire tool pans, separation disks and arc-shaped tool plates on a spline shaft, which has complicated processing and various kinds of cutters, and makes the spline shaft easy to loosen. The integrated tool holder for the first pulverizer is formed by the following steps: two adjacent tool pans and a separation disk between the tool pans are welded and fixed into a whole to become a unit integrated tool holder; and then a plurality of sections of unit integrated tool holders M are assembled. A transmission shaft is driven by a flat key. Thus when longitudinal and transverse cutters are suspended on the two tool pans, the operations are performed inside each unit integrated tool holder independently and are not correlated with each other; and all spline holes, mounting grooves, gasket counterbores and so on, do not need to be synchronously processed, which can ensure that the tool holder does not transplace or distort. Five types of longitudinal cutters are reduced to two types of longitudinal cutters. The rigidity and the strength of the whole tool holder are increased, and the tool holder is convenient to disassemble and assemble. When the flat key is used, the flat key is easy to repair when the flat key is damaged, thereby quickly clearing faults and restoring the production.

Description

The first pulverizer monoblock type knife rest

(1) technical field: the first pulverizer monoblock type knife rest belongs to the equipment class (B29B) of the preform of a kind of processing PVA (vinylon industry polyvinyl alcohol) or plastics.

(2) background technology:

The utility model relates to the cutter frame structure on PVA first pulverizer (following summary for ' one powder the machine ') rotor.' one powder machine ' be one of key equipment on vinylon industry polyvinyl alcohol (PVA) the alcoholysis production line, see Fig. 6, its mechanism is by ' one powder machine ' rotation of the high speed of knife rest, be installed in longitudinal knife 5 on the knife rest and revolving knife 6 and be installed in ' one powder machine ' fixedly chasing tool 9 alternating actions on the body 8, be cut into the bulk PVA material of alcoholysis machine output the fine strip shape of 100 * 6 * 2 sizes.K among Fig. 6 ₁, K ₂Be respectively the charging and discharging direction.

Existing ' one powder machine ' cutter frame structure is very complicated.It is that 8 cutterhead 2N, 7 all are assembled on the splined shaft 1N every dish 3N, 21 arc cutter plate 4N.The structure of each cutterhead 2N is seen Fig. 4 and Fig. 5, all splined hole 2.3N, cutter mounting groove 2.1N, 2.2N and all necessary synchronous processing of heavy stand that connected spacer is installed, just can guarantee knife rest do not misplace, indeformable, to realize mounting smoothly of longitudinal knife 5N, revolving knife 6N.In addition, overlapping owing to having between the adjacent longitudinal knife, on arranging, cutter tooth must dodge mutually, so the kind of longitudinal knife, quantity and arrangement mode are all very loaded down with trivial details.Even more serious is, because splined shaft is bigger in aspect difficulty such as quality of fit, selection and heat treatments, is easy to occur that spline is loosening, wearing and tearing even entirely ineffective situation.And in a single day have an accident, can not repair in the short time, thereby bury hidden danger for producing continuously.

(3) summary of the invention:

The first pulverizer monoblock type knife rest that the utility model provides, processed complex, the cutting knife kind that is exactly the existing first pulverizer rotor upper tool post structure of solution is many, splined driveshaft easily becomes flexible problems such as inefficacy.Its technical scheme is as follows:

The first pulverizer monoblock type knife rest, comprise be loaded between the outer a plurality of cutterheads 2 of power transmission shaft, adjacent two cutterheads every dish 3 and be mounted on longitudinal knife 5 and revolving knife 6 between two cutterheads, be contained in arc cutter plate 4 every the dish periphery, it is characterized in that:

A) be fixed as integral body by what interior cover 3.1 and overcoat 3.2 were formed every dish 3 whole welding between adjacent two cutterheads 2, two cutterheads, be called whole unit knife rest M; The first pulverizer monoblock type knife rest is assembled by two sections or above whole unit knife rest M; B) cover 3.1 endoporus are offered flat key groove 3.3 in, are used to adorn the flat key that is in transmission connection with power transmission shaft.

The utility model beneficial effect:

I. adopt whole unit knife rest M, the longitudinal knife 5 and the revolving knife 6 that are mounted on two cutterheads all independently carry out in each whole unit knife rest M inside, no longer interrelated, the heavy stand of all splined holes, cutter mounting groove and installation connected spacer etc. does not need synchronous processing, all can guarantee knife rest do not misplace, indeformable, to realize mounting smoothly of longitudinal and transverse cutting knife.The longitudinal knife kind significantly is reduced to 2 kinds by 5 kinds.Ii. adopt the structure of combination multistage whole unit knife rest M, the rigidity of whole knife rest and intensity increase, and dismounting is more convenient than old structure.Iii. adopt the general flat key of higher quality of fit to connect, if use has wearing and tearing, damage, the general flat key structure is repaired easily than spline linkage structure, is convenient to fix a breakdown rapidly, resumes production.

(5) specific embodiment:

See Fig. 1, the utility model first pulverizer monoblock type knife rest is sleeved on the power transmission shaft 1 by the whole knife rest M of 5-6 segment unit, and two ends tighten up with axial fastener 7 and form.What draw among Fig. 1 is 5 sections.

See Fig. 2, be fixed as integral body by what interior cover 3.1 and overcoat 3.2 were formed every dish 3 whole welding between adjacent two cutterheads 2 in the whole unit knife rest M, two cutterheads.See Fig. 3, circle has flat key groove 3.3 in the cover 3.1 in dish 3, is used for the higher flat key of installation accuracy, is in transmission connection with power transmission shaft 1.Cutterhead 2 most peripherals are to there being three groups of uniform identical cutter grooves that articulate, and the cutter groove 2.1 that articulates longitudinal knife 5 are arranged in every group, articulate the cutter groove 2.2 of revolving knife 6.Along circumferentially adorning three arc cutter plate 4, available screw thread is loaded on overcoat 3.2 surfaces every dish 3 overcoats 3.2 outsides.

See Fig. 1, see Fig. 3, during with the whole knife rest A assembling of five segment units, flat key groove 3.3 circumferential positions of the whole knife rest M of adjacent two segment units differ equal angular β=60 °, obtain 60 ° of adjacent two sections longitudinal knife 5 or revolving knife 6 circumferential misalignment thus, be convenient to process broken material.
