Description
Technical Field
The invention belongs to the field of textile machinery equipment, and particularly relates to a scraper head.
Background
In the production process of chemical fibers, a molten polyester body is sprayed out from a spraying panel with a plurality of small holes under pressure and is cooled to form filaments. The orifices of the spinneret plate are typically very small, about 0.15mm in diameter. During the production process, polymer is generated, and the small holes are easily blocked or partially blocked, so that the spinning effect and the spinning quality are influenced. Therefore, these spin panels require periodic cleaning. In the prior art, the manual cleaning mode is common, but the manual cleaning is time-consuming and labor-consuming, the efficiency is low, and the cleaning effect is not ideal. Therefore, a scraper head specially used for cleaning the spinning panel is developed and designed, and the spinning panel is cleaned by a blade rotating under the action of power. But the structure of current scraper head is complicated, and the dismouting is very inconvenient.
Disclosure of Invention
The scraper head provided by the invention is convenient to disassemble and assemble.
The technical scheme of the invention is as follows: the utility model provides a scraper head, includes the blade disc, set up blade subassembly on the blade disc, wear to locate the rotation axis on the blade disc and wear to locate the epaxial floating spring of rotation, still including wearing to overlap in the outside support axle sleeve of rotation axis, the floating spring butt is between blade disc and support axle sleeve, connect through the key slot mechanism of axial fixity connection and the fixed draw-in groove mechanism of circumference between rotation axis and the support axle sleeve.
The floating spring is abutted between the supporting shaft sleeve and the cutter head, when the cutter head rotates and the blade assembly is in contact with the spinning panel for cleaning, under the elastic force action of the floating spring, the friction force between a cutter head in the blade assembly and the spinning panel can be reduced, and the protection effect can be achieved.
The key groove mechanism has various structural forms, can adopt various existing modes, and preferably consists of a key groove formed in the rotating shaft and a convex key arranged on the inner wall of the shaft sleeve.
The clamping groove mechanism has various structural forms, can adopt various existing modes, and preferably comprises a positioning groove formed in the side wall of the rotating shaft and a positioning piece arranged on the support shaft sleeve and matched with the positioning groove.
Preferably, the positioning piece comprises an extrusion spring arranged on the supporting shaft sleeve and a steel ball arranged at one end of the extrusion spring, and the steel ball extends into the positioning groove under the elastic force action of the extrusion spring. During installation, the supporting shaft sleeve axially moves along the rotating shaft under the action of the elastic force of the floating spring, and when the steel balls correspond to the positioning grooves in position, the steel balls are fixed in the positioning grooves under the action of the elastic force of the extrusion spring, so that circumferential fixation is realized.
Preferably, a set screw penetrates through the support shaft sleeve, and the extrusion spring is fixed on the set screw.
Preferably, the positioning groove is an annular groove arranged circumferentially along the rotary shaft.
Preferably, the positioning member is a plurality of positioning members, and the plurality of positioning members are uniformly arranged along the circumferential direction of the annular groove.
Preferably, the number of the positioning pieces is 4.
Compared with the prior art, the invention has the beneficial effects that:
when the supporting shaft sleeve is installed, the axial direction of the rotating shaft and the axial direction of the supporting shaft sleeve are fixed through the key groove mechanism, circumferential fixing is achieved through the clamping groove mechanism, the supporting shaft sleeve is very convenient to assemble and disassemble, and the assembling and disassembling efficiency is improved.
