Description

Technical Field

[0001] The utility model relates to the technical field of fixed knives for pulverizers, in particular to a high-strength fixed knife for a plastic cutting pulverizer. Background Art

[0002] A pulverizer is a machine that crushes large-sized solid raw materials into required sizes. The pulverizer consists of coarse crushing, fine crushing, wind conveying and other devices. It achieves the purpose of the pulverizer in the form of high-speed impact and uses wind energy to pulverize the raw materials in one step, eliminating the traditional screening process. It is mainly used in mining, building materials and other industries.

[0003] For example, the patent document with the announcement number CN 209934897 U discloses a high-strength fixed blade head for a metal cutting pulverizer, including a blade body, a front blade head and a rear blade head. The blade body is an M42 steel blade body, the front end face of the blade body is the front blade head, the rear end face of the blade body is the rear blade head, and the blade body, the front blade head and the rear blade head are an integral structure. Fixed slots are respectively provided on the upper and lower end faces of the blade body, the distance between the rear blade head and the fixed slot is greater than the distance between the front blade head and the fixed slot, and more than two screw holes are respectively provided on the side wall of the blade body. The cutting tool blade head of the utility model is made of M42 steel. The M42 steel has high hardness, which can reach 70HRC, good hot hardness, high high temperature hardness, and is easy to cut. It can cut iron-based high-temperature alloys, cast high-temperature alloys, titanium alloys and ultra-high strength steels, etc.

[0004] However, in the actual process of using this structure, it is often only possible to perform simple installation and use operations of the high-strength fixed knife for plastic cutting and crushing machines. When the plastic fixed knife is subsequently disassembled and assembled separately, the tightness of the connection cannot be guaranteed, which affects the effect of the fixed knife plastic cutting and crushing. At the same time, the equipment cannot perform tight splicing, installation and use operations between multiple sets of cutting rollers, and cannot be replaced and used more stably separately later, which cannot meet daily use needs. Therefore, it is urgent to design a high-strength fixed knife for plastic cutting and crushing machines to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a high-strength fixed knife for a plastic cutting and crushing machine, so as to solve the problem that the existing structure proposed in the above background technology can often only perform simple installation and use operations of the high-strength fixed knife for plastic cutting and crushing machine in the actual process, and the tightness of the connection cannot be guaranteed when the plastic fixed knife is disassembled and assembled separately later, which affects the effect of the fixed knife plastic cutting and crushing. At the same time, the equipment cannot perform tight splicing, installation and use operations between multiple groups of cutting knife rollers, and cannot perform more stable separate replacement and use later, and cannot meet daily use needs.

[0007] The blade body is fixedly connected to the four sides of the side of the mounting roller seat, a positioning frame is arranged at the bottom end of the back side of the clamping groove, and a mounting seat is fixedly connected to the bottom end of the front side of the blade body.

[0008] Preferably, a fixing sleeve is provided inside the mounting seat, and a fixing bolt is provided on the inner wall of the fixing sleeve.

[0009] Preferably, an arc-shaped contraction frame is provided inside the positioning frame, and an arc-shaped top plate is movably connected inside the arc-shaped contraction frame.

[0010] Preferably, a top joint is fixedly connected to the bottom end of the arc-shaped top plate, and the top joint is adapted to the positioning frame.

[0011] Preferably, movable grooves are provided inside the first conical cover and the second conical cover, a connecting groove is provided inside the mounting roller seat, and sealing rings are provided on the sides of the first conical cover and the second conical cover.

[0012] Preferably, both sides of the first conical cover and the second conical cover are movably connected with a retractable seat, and the side surfaces of the retractable seat are provided with a top connecting plate.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The high-strength fixed blade for the plastic cutting and pulverizing machine can make the equipment more stable for plastic cutting and pulverizing at the blade body by means of the arranged mounting roller seat, the clamping groove, the first conical cover, the second conical cover, the blade body, the positioning frame, the mounting seat, the fixing sleeve, the fixing bolt, the arc-shaped shrinking frame, the arc-shaped top plate and the top joint. In the actual use process, the staff can install multiple sets of positioning frames at the clamping groove at the center of the side of the mounting roller seat through the mounting seat at the bottom, and quickly carry out adaptive docking of the blade body at the mounting roller seat and the second conical cover at both ends and the blade body. The positioning frame is first adapted to be offset and fixed with the mounting seat inside the clamping groove. At this time, the arc-shaped top plate and the top joint are contracted through the arc-shaped contraction frame inside the positioning frame, and stably fixed on the mounting seat at the bottom of the blade body, so that the mounting seat can be stably fastened at the clamping groove of the mounting roller seat. Finally, it is only necessary to fix the fixing sleeve inside the mounting seat with a fixing bolt to ensure high-strength plastic cutting and crushing operations of all blade bodies on the mounting roller seat. The single blade body can also be quickly disassembled and replaced at any time later, which reflects the practicality of the equipment design.

[0015] The high-strength fixed blade of the plastic cutting pulverizer further improves the overall use effect of the equipment by arranging an installation roller seat, a clamping groove, a first conical cover, a second conical cover, a blade body, a movable groove, a connecting groove, a sealing ring, a shrinkage seat and a top connecting plate. In daily use, the staff can install the shrinkage seat and the top connecting plate through the installation roller seat and the movable grooves and connecting grooves of the first conical cover and the second conical cover at both ends, and then use the adaptive docking between the shrinkage seat and the top connecting plate to quickly install and use multiple groups of installation roller seats, first conical covers and second conical covers in a adaptive docking combination. The first conical cover and the second conical cover are then sealed and tightly fitted by the sealing ring on the side edge, so as to ensure the stability of the use of the pulverizing roller composed of the multiple groups of installation roller seats at all times, and can also perform individual quick disassembly and maintenance operations later, which reflects the comprehensiveness of the equipment design.
