Abstract
The invention discloses a compression roller device of a double-screw extruding and tabletting machine for a powder coating and aims at solving the technical problem that a clearance between an upper compression roller and a lower compression roller is gradually enlarged along with the prolonging of working time because the compression roller device is used for a long term. The compression roller device is provided with a limiting plate and a compression spring, so that a reasonable clearance is continuously kept between the upper compression roller and the lower compression roller under the action of the compression spring. The compression roller device is simple in structure, low in modification cost and remarkable in effect.
Description
Technical field
The present invention relates to powdery paints production technical field, particularly relate to a kind of press-roller device of powdery paints twin-screw extrusion tablet press.
Background technology
Powdery paints is form diverse with general coating, and it exists with the state of attritive powder.Owing to not using solvent, so be called powdery paints.Powdery paints be a kind of novel, not containing solvent, 100% solid powdery coating, have without solvent, pollution-free, save the energy and resource, reduce labor intensity and film mechanical strength high.
It has two large classes: thermoplastic powder coating and thermosetting powder coating.
Thermoplastic powder coating is become to be grouped into stabilizing agent etc. by thermoplastic resin, pigment, filler, plasticizer.Thermoplastic powder coating comprises: polyethylene, polypropylene, polyester, polyvinyl chloride, chlorinated polyether, polyamide-based, cellulose-based, Polyester.
Thermosetting powder coating is made up of thermosetting resin, curing agent, pigment, filler and auxiliary agent etc.Thermosetting powder coating comprises: epoxy resin, Polyester, acrylic resin.
Extruded by double screw extruder after the procedure of processing of powdery paints is mixed by raw material, then the thin slice that pressure roller becomes area larger, deliver to pressure roller by conveyer belt and be ground into fragment, finally fragment is sent into flour milling unit and make powdery paints.Pressure roller comprises pressure roller and lower compression roller, and both are cylindric horizontally disposed, and centre is left gap and entered for thin slice, and its weak point is: upper gap between pressure roller and lower compression roller increases gradually along with the increase of working time, causes crushing effect to reduce.
Summary of the invention
The object of the invention is the technological deficiency for existing in prior art, and a kind of press-roller device that can keep the powdery paints twin-screw extrusion tablet press of pressure roller crushing effect is provided.
The technical scheme adopted for realizing object of the present invention is: a kind of press-roller device of powdery paints twin-screw extrusion tablet press, it is characterized in that comprising upper pressure roller and lower compression roller that two levels stack, is formed with gap between the two; Described upper pressure roller and lower compression roller are cylinder-like structure, and its two ends are respectively arranged with rotating shaft, and described rotating shaft is arranged with the support for supporting revolving shaft; The barrel of upper pressure roller and lower compression roller spreads all over the tip had for pulverizing; The rotating shaft of described lower compression roller one end is provided with driven gear; Described driven gear is connected with driving gear by chain; The top back-off of described support has the limiting plate of spill, and described limiting plate is connected with described support by rivet; Middle part and the described support of described limiting plate form dead slot, and described dead slot place is provided with Compress Spring.
The side that described support is being positioned at described chain is fixed with base, and described base is fixed with bearing pin.
Described base is the H-shaped structure that both sides have horizontal draw-in groove, and horizontal draw-in groove place is equipped with clamping screw.
The outer wall cover of described bearing pin has cylindric metal jacket casing, and the fill gaps between the inside of described metal jacket casing and the outer wall of described bearing pin has multiple ball.
The invention has the beneficial effects as follows: due to Long-Time Service, gap between upper pressure roller and lower compression roller increases gradually along with the increase of working time, the present invention is by being provided with limiting plate and Compress Spring, under the effect of Compress Spring, make pressure roller and lower compression roller continue to keep rational gap, its structure is simple, improvement cost is low, successful.

Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Embodiment:
Be illustrated in figure 1 a kind of press-roller device of powdery paints twin-screw extrusion tablet press, comprise upper pressure roller 1 and lower compression roller 2 that two levels stack, be formed with gap between the two; Described upper pressure roller 1 and lower compression roller 2 are cylinder-like structure, and its two ends are respectively arranged with rotating shaft, and described rotating shaft is arranged with the support 3 for supporting revolving shaft; The barrel of upper pressure roller 1 and lower compression roller 2 spreads all over the tip had for pulverizing; The rotating shaft of described lower compression roller 2 one end is provided with driven gear 4.
Shown in Fig. 2, described driven gear 4 is connected with driving gear 6 by chain 5; The top back-off of described support 3 has the limiting plate 7 of spill, and described limiting plate 7 is connected with described support 3 by rivet 8; Middle part and the described support 3 of described limiting plate 7 form dead slot, and described dead slot place is provided with Compress Spring 9.Due to Long-Time Service, gap between upper pressure roller 1 and lower compression roller 2 increases gradually along with the increase of working time, the present invention is by being provided with limiting plate 7 and Compress Spring 9, just can adjust the compression distance of Compress Spring 9 by turning rivet 8, under the effect of Compress Spring 9, making pressure roller 1 and lower compression roller 2 continue to keep rational gap.
As shown in Figure 3, the side that described support 3 is being positioned at described chain 5 is fixed with base 10, and described base 10 is fixed with bearing pin 11; The H-shaped structure of base 10 horizontal draw-in groove for both sides have, horizontal draw-in groove place is equipped with clamping screw 12.Long-time use can make chain occur to loosen, and by adjusting the relative position of clamping screw 12 and base 10, just can adjust the position of bearing pin 11, making chain be in preferably degree of tightness state.
Further, as shown in Figure 4, the outer wall cover of described bearing pin 11 has cylindric metal jacket casing 13, fill gaps between the inside of described metal jacket casing 13 and the outer wall of described bearing pin 11 has multiple ball 14, ball 14 can avoid chain and bearing pin 10 to wear and tear, thus has influence on the service life of chain.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
