Abstract
The invention relates to an auxiliary device for a modified plastic extruder, in particular to a lapping device for a modified plastic extruder producing broken chain in an extrusion process. An automatic lapping device for a plastic extruder comprises an extruder head (1) which is horizontally provided with extrusion holes (2) in rows; the front part of the extruder head (1) is provided with an annular revolving transmission chain (4) encircling the extrusion holes (2); and the transmission chain (4) is provided with a plurality of bar rams (3) extended to a chain conveying direction. The lapping device automatically laps the broken chain at any time through constant movement so as to overcome the defect of manual lapping in the prior art, effectively stop the production of bulk materials and achieve better effect compared with the manual lapping; and the lapping device does not need manual monitoring and manual operation, and can repair the broke material in time and ensure normal operation.
Description
(1) technical field
The present invention relates to a kind of servicing unit of Modified plastic extruder, especially be a kind of Modified plastic extruder disconnected bar appears in extrusion and the time lapping device.
(2) background technology
Known; an expressing technique link is arranged in processing modified plastics; be to add in the process equipment extruder after various raw material fully mix by high mixer; by many modified plastics billots of extruder extrusion molding; enter again pelleter cut-out granulating and finish processing, produce the plastics of different qualities.Can cause unavoidably powder to produce with particle in mixing material process and material movement process separates; in addition; being subjected to the extrusion exhaust and vacuumizing affects, and the billot of extruding in extrusion can cause unavoidably and have some setbacks, occurs unusually, finally causes extruder material strip out often to have disconnected bar and occurs.
Solution behind the at present disconnected bar normally will be broken down with quick-moving speed by the employee and the material strip that continues to extrude has been picked up; ride over that adjacent other is disconnected, on the normal operating material strip; carry out pelletizing by adjacent good material strip, normal synchronous transport to the pelleter that reaches in service, to guarantee normal purpose of producing.
There is following shortcoming in such means to save the situation, if during disconnected bar the employee find untimely or the employee not at the scene, disconnected bar will occur and pile up until all material strips are all broken, form the bulk material, general bulk material does not all reclaim, and does Transition Materials and loses, have a strong impact on output capacity, cause the cost waste.All more than 200 degree, the employee takes bar with hand also has certain injury to health to the plastics temperature of fusing on the other hand, and extruding the operative employee all has in various degree scald on hand, unhealthful.Moreover the employee often sees that bar takes bar and also affect normal operation, has reduced greatly employee's operating efficiency, increases burden to the employee.After this production scene an urgent demand changes mends the measure present situation, alleviates and avoids above defective.
(3) summary of the invention
Purpose of the present invention is intended providing a kind of artificial supervision that do not need, and does not need manually-operated, finishes by the normal operation of adjacent continuous material strip in the time of in time remedying fracture and occur and takes the operation that bar transports.
The objective of the invention is to be achieved through the following technical solutions:
A kind of automatic lapping device of plastic extruder, comprise the extruder head that is the extrusion cavities in a row that level offers, it is characterized in that, an annular running driving-chain around extrusion cavities is set in described extruder head front portion, on driving-chain, arrange many to the material strip throughput direction and choose the bar bar.
Evenly the bar bar is chosen in the spacing distance setting on described driving-chain.
The described adjacent spacing of bar bar of choosing is 4 to 15 centimetres.
The described bar bar of choosing is in level up and down in the 30 degree angular range.
Described driving-chain speed of service adjustable range is 10 to 30 centimetres of per seconds.
The sprocket wheel of described driving-chain configuration different-diameter.
Described driving-chain is by motor-driven.
Adopt the technical program; the many bars that are arranged on the driving-chain are chosen the continuous extrusion cavities operation that stably centers on the extruder head of bar bar; the material strip that falls of not breaking is transported to the pelleter direction from the normal operation of driving-chain central portion of annular; when the disconnected bar of material strip occurs; anterior fracture will continue to be advanced by the traction of the haulage gear in the place ahead; and that follow-up material strip has lacked the traction in the place ahead is can only be naturally mobile vertically downward by gravity; drive the material strip transverse shifting when driving choosing the bar bar and running into sagging fracture bar of transverse shifting by driving-chain and around falling to the top; automatically with the plastic strip adhesion that has just gone out; substitute original bar of manually taking; moved forward by sticking the taking in the lump of the material strip of normal operation; reach safety; automatically; the artificial purpose of bonding jumper, the defects that exists to overcome prior art.
There is the above as seen, the invention has the beneficial effects as follows fairly obvious, the moving bar that will break is at any time taken bar automatically by not stopping transport, solved the weak point that prior art is manually taken bar, the generation of effectively stopping the bulk material has realized than manually taking the better effect of bar, a kind of artificial supervision that do not need is provided, do not need manually-operated, can in time remedy fracture, guarantee a kind of lapping device of normal operation.

(5) specific implementation method
Below in conjunction with accompanying drawing, the present invention is elaborated:
A kind of automatic lapping device of plastic extruder, comprise the extruder head 1 that is the extrusion cavities in a row 2 that level offers, in described extruder head 1 front portion the one annular running driving-chain 4 around extrusion cavities 2 is set, on driving-chain 4, arranges many to the material strip throughput direction and choose bar bar 3.Evenly bar bar 3 is chosen in the spacing distance setting on driving-chain 4.Choosing bar bar 3 adjacent spacings is 4 to 15 centimetres.Choose bar bar 3 in level up and down in the 30 degree angular range.
Driving-chain 4 speed of service adjustable ranges are 10 to 30 centimetres of per seconds.The sprocket wheel 5 of driving-chain 4 configuration different-diameters.
Driving-chain 4 is driven by motor 6.
At first make driving-chain 4 length according to cross-head 1 size, and make a sprocket wheel 5 and speed varying chain wheels 8, driving-chain 4 can be formed rotatable rotation driving-chain 1 on sprocket wheel 5 and speed varying chain wheels 8, on driving-chain 1, arrange many every 4 to 15 centimetres to the material strip throughput direction and choose bar bar 3, choosing bar bar 3, to stretch out angle be the 60-120 degree, the level that namely is controlled at is up and down in the 30 degree angular range, otherwise is not easy disconnected bar is hooked; In speed varying chain wheels 8 sides synchronous motor 6 is installed again, rotate control, the plugged line is also installed power switch box at sidepiece, the present invention namely completes, before the present invention is installed in extrusion main unit head 1, extrusion cavities 2 just is positioned in the middle of the conveyer chain 4, not only can not affect production but also can realize the purpose that disconnected bar is taken bar.
