Description

A kind of disintegrator knife chamber

Technical field

The utility model belongs to field of mechanical technique, and in particular to a kind of disintegrator knife chamber.

Background technology

In the injection process of rubber or working of plastics, due to the requirement of injection technique and mold design, typically all can or it is more Or gate materials are left less, the gate materials of these rubber or plastics can be with recycling.And during gate materials recycling, typically To be crushed by rubber-plastic thresher, could be mixed after dedusting with virgin material after be injection moulded.Current various in the market institutes Two pieces of knife chamber pieces that the crushing chamber of the plastic crusher of sale generally comprises front and rear end plate and is fixedly connected with front and rear end plate are formed, Cutter runs through front and rear end plate and is supported on by bearing on front and rear end plate.The top of two pieces of knife chamber pieces is charging aperture, is pacified to fixed Cast hopper is filled, bottom is discharging opening, discharge bucket is fixedly mounted.Motor is driven by being arranged on the transmission mechanism of front end front edge of board Cutter is rotated, and by the collective effect of cutter and knife chamber, the rubber entered in crushing chamber or plastics are crushed.Above-mentioned knife Chamber is fully closed structure design, and this mainly goes what is considered in terms of Intensity Design, because rubber or plastics are when crushing Very big pressure can be produced, it is necessary to which the relatively good knife chamber of an intensity adapts to therewith.And in practice process, in order to assign The intensity that knife chamber more arrives, sometimes also it can design some reinforcements in knife chamber.Although above-mentioned closed knife chamber ensure that its intensity, To bear pressure when crushing, but there is also the cutter in cavity and in cavity to clean the problem of inconvenient, easily leaves clear The dead angle swept.Just because of above-mentioned using the problems of closed knife chamber, some current pulverizers are caused to crush one Occur mixing phenomenon after kind of rubber or plastics, then when crushing a kind of rubber or plastics, make recovery rubber or plastic material by Pollution.Because the working process parameter between different rubber or plastics differs.These contaminated rubber or plastics, Many problems can be run into during post-production, welded side seam, bubble cavity, color occur in such as rubber of processing or working of plastics It is uneven etc., decline the product quality of processing, have influence on the recycling using waste old or plastics, particularly gate materials.

But the open angle of existing combined knife chamber is smaller, it is impossible to opens completely, can thus influence to clear up, cause Cleaning is not thorough, in cleaning is also possible to that hand or other positions of body can be run into；And the composition cutter groove of combined knife chamber After arc groove is all integrated into left and right knife chamber installing plate, in order to prevent being touched when left and right knife chamber installing plate flips over To cutter, it is necessary to the joint of left and right knife chamber installing plate is cut out downwards into a part so that in the arc groove in junction With one downward " pit ", some piece materials can be accumulated here in use, cause crushing material not thorough, Sometimes the solid accumulation in pit is excessive, can also hinder the operation of blade.

The content of the invention

It is smaller in order to solve the open angle of existing combined knife chamber, it is impossible to open completely, influence to clear up, in cleaning It is also possible to the people that can damage；The problems such as also producing solid accumulation in knife bottom of chamber portion.Provide that a kind of open angle is big, structure is simple Single, intensity height, it is convenient for changing a kind of disintegrator knife chamber of cutter.
