Abstract

The invention relates to a blade hold-down mechanism for a plastics granulator. The blade hold-down mechanism is characterized by comprising a fixed block, wherein the fixed block is provided with a through hole which is internally provided with a guide column, two ends of the guide column stretch out of two sides of the fixed block, one end of the guide column is provided with outer threads and is provided with a nut, the other end of the guide column is connected with a tool apron, a compression spring is sheathed on the section of guide column between the tool apron and the fixed block, the tool apron is provided with a blade clip, and a blade is fixed on the blade clip. By adopting the blade hold-down mechanism, the amount of feed of the blade can be automatically regulated, so that the cutting edge of the blade is always attached to the model head surface, the appearance of plastic particles and the production efficiency are not affected, and the maintenance cost can be lowered.

Description

Plastic granulator granulating device blade pressing mechanism
Technical field
The present invention relates to the plastic granulator granulating device, is for the blade pressing mechanism of the adjustable blade depth of cut automatically on the plastic granulator granulating device specifically.
Background technology
As everyone knows, in the plastic cement industry, the plastic particles series products be all generally by extruding, the mode of pelletizing produces.The method kind of pelletizing is more, this is wherein modal is exactly two kinds of flour milling pelletizing and water smoke pelletizings, their principle be all make the blade of monolithic or multi-disc cutting knife be skewed be close to porous die face on, and circle, make again the plastic cement after melting flow out from the aperture of die face, plastic cement is cut by cutting knife in the process flowed out, and then by its cooling getting final product.This structure is through being used for a long time, and cutting knife is easy to wear and tear, make between cutting knife blade and die face gapped, thereby cause the particle size inequality cut or adhesion arranged, affect particle outward appearance and production efficiency.At this moment, in order to guarantee the cutting knife blade, be close to die face all the time, just need to apply an axial compressive force to cutoff knife rack, cutting knife is pressed on die face.Yet, between blade, the different degrees of wear causes single force mechanism can't guarantee that each blade is pressed on die face, once occur that indivedual blades are not pressed on die face, just must change all blades simultaneously or the more serious blade of wearing and tearing is adjusted, so not only need to expend a large amount of labours, but also can waste blade, make the maintenance cost increase.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of plastic granulator granulating device blade pressing mechanism, adopt this hold-down mechanism, automatically the depth of cut of adjustable blade, make the blade of blade be close to all the time on die face, do not affect plastic particles outward appearance and production efficiency, can reduce the maintenance cost yet.
For addressing the above problem, take following scheme:
Plastic granulator granulating device of the present invention is to comprise fixed block by the characteristics of blade pressing mechanism, and through hole is arranged on fixed block, and lead is arranged in through hole.All stretch out from the fixed block both sides at the two ends of described lead, and an end of lead is processed with on external screw thread and its nut, and the other end of lead is connected with tool rest, and on that section lead between tool rest and fixed block, cover has Compress Spring.On described tool rest, cutting blade clip is arranged, be fixed with blade on cutting blade clip.
The further improvement of the present invention scheme is that the quantity of through hole on described fixed block is two, and the axis of two through hole is parallel.In described two through holes, lead is all arranged, all be processed with external screw thread on the same corresponding end of two leads and cover has nut, another corresponding end of two leads all is connected on described tool rest.Between the plane at the axis place of described two leads and the median plane of blade, angle is arranged.The structure of the two leads of employing can be strengthened the structural rigidity of this hold-down mechanism, avoids causing knife rest to tilt or the blade distortion because accepting inequality.
Take such scheme, have the following advantages:
Owing on the fixed block of plastic granulator granulating device of the present invention with blade pressing mechanism, through hole being arranged, lead is arranged in through hole, one end of lead is processed with on external screw thread and its nut, the other end is connected with tool rest, on that section lead between tool rest and fixed block, cover has Compress Spring, cutting blade clip is arranged on tool rest, be fixed with blade on cutting blade clip.This structure is the equal of to be provided with spring-compressed mechanism between tool rest and fixed block, fixed block is fixed in the rotating shaft of plastic granulator granulating device, and the nut on the adjustment lead, the thrust that makes tool rest be compressed spring on die face, and makes Compress Spring leave certain springback capacity blade pressing.Granulating device in use, when wearing and tearing occur in blade, Compress Spring is the push-tight tool rest all the time, make blade and die face be close to, thereby not there will be the gap between blade and die face, just can not cause the particle size inequality cut yet or adhesion is arranged, so can not affect particle outward appearance and production efficiency.And each blade has Compress Spring separately to be compressed, the reserved springback capacity of Compress Spring can guarantee that blade is close on die face all the time, thereby can reduce the replacing of blade and adjust frequency, thereby reduces the maintenance cost.

The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in Figure 1, Figure 2 and Figure 3, plastic granulator granulating device of the present invention comprises fixed block 2 with blade pressing mechanism, and two through holes that are arranged side by side are arranged on fixed block 2, and the axis of two through hole is parallel, and in through hole, lead 3 is all arranged.All stretch out from fixed block 2 both sides at the two ends of lead 3, all be processed with on the same corresponding end of two leads 3 on external screw thread and its nut 1 is arranged, another corresponding end of two leads 3 has a tool rest 5, all be and be fixedly connected with between the corresponding end of tool rest 5 and two leads 3, on two sections leads 3 of that between tool rest 5 and fixed block 2 all cover Compress Spring 4 is arranged.On described tool rest 5, cutting blade clip 6 is arranged, be fixed with on cutting blade clip 6 between the median plane of the plane at axis place of blade 7, two leads 3 and blade 7 angle is arranged.
As shown in Figure 4 and Figure 5, during use, plastic granulator granulating device of the present invention is fixed in the rotating shaft 8 of plastic granulator granulating device with the fixed block 2 of blade pressing mechanism, and the nut 1 on adjustment lead 3, the thrust that makes tool rest 5 be compressed spring 4 is pressed on blade 7 on die face 9, and make Compress Spring 4 leave certain springback capacity, use that so just can be relieved.
