Description
Technical field
The invention belongs to plastic sheet production technical field, the micro device of particularly plastic sheet product sampling.
Background technology
At present, the sampling for various plastic raw materials product detects generally excises a part of exemplar in whole product, and need of production starts whole production line, and sampling time is of a specified duration, and fabrication cycle is long, and waste is serious.
Summary of the invention
For overcoming above-mentioned technical problem, the invention provides a kind of plastic sheet sampler, utilizing micro plastic extruder extrusion sheet product, by miniature tri-roll press machine formed sheet, and then obtaining the samples of sheets of needs easily.
Plastic sheet sampler of the present invention comprises extrusion device, sheet die, press-roller device and heater, and these three devices are fixed in frame.Described extrusion device comprises extruder main frame, extruder barrel, and described press-roller device comprises three roller main frames, pressure roller and governor motion.Distance between described three rollers can be regulated by governor motion between 1 ~ 25mm, and the temperature of extruder barrel can reach 280 DEG C from room temperature.
Three roller main frames are also provided with three shaft hard-tooth surface speed reducers, and adopt chain drive between pressure roller.
Governor motion in described press-roller device comprises adjusting handle, flange platen, take-up housing bearing, regulates screw mandrel, bearing flange and swivel joint, and adjusting handle is by regulating screw mandrel and flange platen connection sliding block seat bearing.
Described extrusion device comprises extruder main frame, extruder barrel, and wherein this extruder barrel bosom is provided with an extrusion screw rod, and outside has heater coated, and described heater comprises clip and heating collar.
Especially, the roller combination of described three roller main frames is vertical with described frame is arranged.
Preferably, described roller can be cylindrical, dolioform, also can at roller surface texturing line.Meanwhile, in three rollers, all there is recirculated cooling water to pass through, in order to samples of sheets cooling, accelerate shaping, shorten sample time.
Described swivel joint is also installed an anti-rotation sheet to be used for limiting rotation, make the mouth of a river all the time down.
Overall volume 750mm*450mm*700mm of the present invention, because volume is little, heating is fast, and save the time, driving power is little, reduces energy consumption.

Detailed description of the invention
Technical scheme of the present invention is illustrated below in conjunction with accompanying drawing:
As shown in Figure 1, 2, 3, stand type support 15 is fastened by bolts in frame 1, pressure roller 4 is arranged in stand type support 15 by take-up housing bearing 16 or band square base bearing 18, adjusting handle 3 is by regulating screw mandrel 9 and flange platen 14 connection sliding block seat bearing 16, adjustment screw mandrel 9 is driven to rotate in the nut 13 be fixed in stand type support 15 by rotating handwheel 3, take-up housing bearing 16 slides up and down relative to stand type support 15, to regulate the gap between pressure roller 4.
Pressure roller 4 one end is threaded connection swivel joint 2, and swivel joint 2 limits with anti-rotation sheet 17 and rotates, and makes the mouth of a river all the time down; The other end is connected by movable sprocket 10 by key, and three roller main frames 6 drive pressure roller 4 to rotate by chain drive, and three roller main frames 6 are bolted in frame 1.Swivel joint 2 connects circulating water pipe.Pressure roller 4 inside is referring to Fig. 4.
As shown in Figure 5, extruder main frame 7 is fastened by bolts in frame 1, and extruder barrel 19 is bolted on extruder main frame, extruder barrel is coated with clip 12, heating collar 11, and connecting hopper 5, head end is by screw thread and Flange joint sheet die 8.
Wherein, extruder barrel 19 bosom is provided with an extrusion screw rod.
Especially, the roller combination of described three roller main frames 6 is vertical with described frame 1 to be arranged, and three roller main frames 6 is also provided with three shaft hard-tooth surface speed reducers, and adopts chain drive between pressure roller 4.
Described roller can be cylindrical, dolioform, also can at roller surface texturing line.Meanwhile, in three rollers, all there is recirculated cooling water to pass through, in order to samples of sheets cooling, accelerate shaping, shorten sample time.
During use, first open heating collar switch, heating 15-20 minute.Then, raw material is put into hopper 5 and enter extruder barrel 19 subsequently, heat through heating collar 11, extrude from sheet die 8 after extruder host driven extrusion screw rod is mixing, roll after cooling forming through pressure roller 4 and become PE articles of sheet material.
When dallying, motor rotary speed is brisk, can become heavier after pan feeding, if become very painstaking, please stopping immediately, may be that extrusion screw rod warm-up time is too short or temperature is low.
After die extrusion raw material, between raw material traction to three rollers, draw in turn, action is wanted fast, attendant exclusion band gloves.
After pulling out, formed sheet, detect thickness, regulates gap, again measures until qualified.
