Abstract

The utility model discloses grinding device of a plastic wet grinding mill, which comprises a lower die base and an upper die base arranged right above the lower die base, wherein the upper die base is connected with the lower die base through at least two groups of drive cylinders; an upper grinding disc is fixedly arranged in the upper die seat, a lower grinding disc is arranged in the lower die base, and the lower grinding disc is driven by a motor; and a feeding hopper is arranged on the upper end of the upper die base, a feeding channel communicated with the lower end part of the feeding hopper is arranged between the upper die base and the upper grinding disc, and a discharge port is arranged in the side of the lower die base. Because the upper die base and the lower die base respectively provided with the upper grinding disc and the lower grinding disc are connected by using the drive cylinders, thus in a plastic grinding process, the control box controls the drive cylinders to operate for maintaining a center pressure between the upper grinding disc and the lower grinding disc, plastic particles can be well ground in premise of uniform force, thus the plastic particles are uniform in size after being grinded, and can be once grinded.

Description

A kind of lapping device of plastics levigator

Technical field

The utility model belongs to the plastic processing machinery equipment technical field, is specifically related to a kind of lapping device of plastics levigator.

Background technology

The pulverizing of prior art plastics (like polytetrafluoroethylene (PTFE)), lapping device adopt the mode of dry grinding basically, and its deficiency is in the high speed process of lapping, to produce high temperature when mill, and it is rotten to cause the partly plastic powder particle to burn.On the other hand, can discharge continuously in order to make the plastic grain of claying into power, generally also need use air blast with the plastic grain sucking-off, through gunny the plastic powders particle collected, whole work flow comparatively bothers.The part levigator is also arranged on the market, and they generally adopt the fixing mill of two relative positions to come plastics are ground, and grind the plastic powders granular size of coming out like this and differ, and need the plastic grain of larger particles be ground once more inefficiency.

Summary of the invention

The purpose of the utility model is: the deficiency to prior art plastics grinding machinery troublesome poeration, inefficiency provides a kind of rational in infrastructure, the lapping device of the plastics levigator that grinding efficiency is high and easy to operate.

For realizing the purpose of the utility model, adopt following technical scheme to be achieved: a kind of lapping device of plastics levigator, include die shoe, be arranged at the upper bolster directly over the die shoe; Said upper bolster drives cylinder through at least 2 groups and is connected with die shoe; Be set with upper millstone in the described upper bolster, be provided with lower millstone in the described die shoe, described lower millstone is by motor-driven; Described upper bolster upper end is provided with feed hopper, and is provided with the feeding-passage that is communicated with the feed hopper bottom in the middle of upper bolster and the upper millstone, and described die shoe side is provided with discharging opening.

As preferred version: described die shoe is fixedly installed on the support, also is provided with in the described die shoe in order to the fixing abrasive disk seat of lower millstone, and said abrasive disk seat is coaxially connected with a driven pulley, and driven pulley is positioned at the support below; The output shaft of described motor is connected with a driving wheel, and driving wheel also is positioned at the support below; Described driven pulley is connected with driving wheel through driving-belt.

As preferred version: the driving cylinder of described connection upper bolster and die shoe is provided with 3 groups along die shoe periphery equidistance.

Compared with prior art; The beneficial effect of the utility model is: owing between upper bolster that is respectively equipped with upper millstone and lower millstone and die shoe, use the driving cylinder to connect; Like this, in the plastics process of lapping, drive cylinder through control cabinet control and operate and keep keeping between upper millstone and the lower millstone certain pressure; Can guarantee well that plastic grain grinds under stressed uniform prerequisite; Like this, the plastic grain size of grinding after accomplishing is even, only needs once to grind and can accomplish.

The specific embodiment

According to accompanying drawing the specific embodiment of the utility model is done a detailed explanation below.

Embodiment

According to illustrated in figures 1 and 2, the lapping device of the described a kind of plastics levigator of present embodiment includes die shoe 5, is arranged at the upper bolster 7 directly over the die shoe 5; Said upper bolster 7 drives cylinder 4 through at least 2 groups and is connected with die shoe 5; Be set with upper millstone 71 in the described upper bolster 7, be provided with lower millstone 51 in the described die shoe 5, described lower millstone 51 is driven by motor 2; Described upper bolster 7 upper ends are provided with feed hopper 8, and are provided with the feeding-passage 72 that is communicated with feed hopper 8 bottoms in the middle of upper bolster 7 and the upper millstone 71, and described die shoe 5 sides are provided with discharging opening 6.

Described die shoe 5 is fixedly installed on the support 1, also is provided with in the described die shoe 5 in order to the fixing abrasive disk seat 52 of lower millstone 51, and said abrasive disk seat 52 is coaxially connected with a driven pulley, and driven pulley is positioned at support 1 below; The output shaft of described motor 2 is connected with a driving wheel, and driving wheel also is positioned at support 1 below; Described driven pulley is connected with driving wheel through driving-belt 3.

The driving cylinder 4 of described connection upper bolster 7 and die shoe 5 is provided with 3 groups along die shoe 5 periphery equidistance.

Be provided with dividing plate 81 longitudinally in the described feed hopper 8, dividing plate 81 both sides are feed cavity and intake antrum.

Described feed hopper 8 bottoms are provided with the charging stirring-head 83 to lower millstone 51 direction pushers, and feed hopper 8 tops also are provided with charging motor 82, and charging motor 82 output shafts are connected with charging stirring-head 83.

Described driving cylinder 4 is connected with control valve and air pump, described motor 2, drives cylinder 4 and charging motor 82 all is electrically connected with control cabinet 9.

The use of the utility model is such: at first the intake antrum to feed hopper 8 at the uniform velocity supplies water, and adds an amount of plastic flakes in the feed cavity, then through control cabinet 9 starter motors 2,

drive cylinder

4 and 82 work of charging motor.Plastic flakes is being pressed onto between upper millstone 71 and the lower millstone 51 gradually and is being ground gradually under the promotion of charging motor 82; Because lower millstone 51 is done rotation at a high speed under motor 2 drives; Plastic powders particle after the grinding gets rid of under centrifugal action to die shoe 5 inwalls together with water, and finally discharges from discharging opening 6.
