Abstract

The utility model relates to a blade compressing mechanism used for a plastic granulation granule cutting machine. The blade compressing mechanism is characterized by comprising a fixed block. Through holes are formed in the fixed block, and guide pillars are arranged in the through holes. The two ends of each guide pillar extend out of the two sides of the fixed block. External threads are machined at one end of each guide pillar, and nuts are arranged on the threads. The other ends of the guide pillars are connected with a knife holder, and compression springs are arranged on the guide pillars between the knife holder and the fixed block in a sleeved mode. A blade clamp is arranged on the knife holder, and a blade is fixed to the blade clamp. By the adoption of the compressing mechanism, the feed amount of the blade can be automatically adjusted, so that a cutting edge of the blade is always tightly attached to the face of a die head, the appearance and the production efficiency of plastic granules can not be affected, and besides maintenance cost can be reduced.

Description

Plastic granulator granulating device blade pressing mechanism
Technical field
The utility model relates to plastic granulator granulating device, is for the blade pressing mechanism of the adjustable blade depth of cut automatically on plastic granulator granulating device specifically.
Background technology
As everyone knows, in plastic cement industry, 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 flowing out, and then it is cooling.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 cutting or have adhesion, affect particle outward appearance and production efficiency.At this moment, in order to guarantee that cutting knife blade is close to die face all the time, just need to apply an axial compressive force to cutoff knife rack, cutting knife is pressed in die face.Yet, between blade, the different degrees of wear causes single force mechanism cannot 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, making to maintain cost increases.
Utility model content
Problem to be solved in the utility model 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 maintenance cost yet.
For addressing the above problem, take following scheme:
Plastic granulator granulating device of the present utility model is to comprise fixed block by the feature of blade pressing mechanism, has through hole on fixed block, has lead in through hole.All stretch out from fixed block both sides at the two ends of described lead, and one 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 of lead between tool rest and fixed block, cover has Compress Spring.On described tool rest, there is cutting blade clip, on cutting blade clip, be fixed with blade.
Further improvement of the utility model 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, all have lead, be all processed with external screw thread and cover has nut in the same corresponding end of two leads, another corresponding end of two leads is all connected on described tool rest.Between the plane at axis place of described two leads and the median plane of blade, there is angle.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 blade distortion because accepting inequality.
Take such scheme, have the following advantages:
Owing to having through hole on the fixed block of plastic granulator granulating device of the present utility model with blade pressing mechanism, in through hole, there is lead, 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 of lead between tool rest and fixed block, cover has Compress Spring, on tool rest, there is cutting blade clip, on cutting blade clip, be fixed with blade.This structure is the equal of between tool rest and fixed block, to be provided with spring-compressed mechanism, fixed block is fixed in the rotating shaft of plastic granulator granulating device, and adjust the nut on lead, make thrust that tool rest is compressed spring by blade pressing on die face, and make Compress Spring leave certain springback capacity.Granulating device in use, when there are wearing and tearing in blade, Compress Spring is push-tight tool rest all the time, blade and die face are close to, thereby there will not be the gap between blade and die face, just can not cause the particle size inequality cutting or have adhesion, so can not affect particle outward appearance and production efficiency yet.And each blade has Compress Spring separately to compress, 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 maintenance cost.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, Figure 2 and Figure 3, plastic granulator granulating device of the present utility model comprises fixed block 2 with blade pressing mechanism, has two through holes that are arranged side by side on fixed block 2, and the axis of two through hole is parallel, and all has lead 3 in through hole.All stretch out from fixed block 2 both sides at the two ends of lead 3, in the same corresponding end of two leads 3, be all processed with on external screw thread and its and have nut 1, another corresponding end of two leads 3 has a tool rest 5, between the corresponding end of tool rest 5 and two leads 3, be all and be fixedly connected with, on those the two sections of leads 3 between tool rest 5 and fixed block 2, all cover has Compress Spring 4.On described tool rest 5, there is cutting blade clip 6, on cutting blade clip 6, be fixed with between the plane at axis place of blade 7, two leads 3 and the median plane of blade 7 and have angle.
As shown in Figure 4 and Figure 5, during use, plastic granulator granulating device of the present utility model is fixed in the rotating shaft 8 of plastic granulator granulating device with the fixed block 2 of blade pressing mechanism, and adjust the nut 1 on 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.
