Abstract
The utility model discloses a kind of efficient feeding combination unit of twin-screw extrusion testing machine, including feeding device, drawing-in device and vacuum evacuation device；Drawing-in device includes feedstock barrel, the twin-screw in feedstock barrel and the driving mechanism with twin-screw transmission connection；Feeding device includes the broach hopper set on feedstock barrel top, the screw agitation shaft in broach hopper and the stirring motor with screw agitation shaft transmission connection；Vacuum evacuation device includes exhaust outlet, the exhaust pipe connecting with exhaust outlet and the vacuum pump connecting with exhaust pipe on feedstock barrel, and exhaust pipe is equipped with pressure gauge and barometric damper.The heat that the utility model friction generates is less, and shearing suffered by material is also more uniform, the conveying capacity of twin-screw is larger, and extrusion output is more stable, work efficiency is high, material residence time in feedstock barrel is longer simultaneously, is uniformly mixed, the product quality produced is higher.
Description
Technical field
The utility model relates to feeder field, especially a kind of efficient feeding of twin-screw extrusion testing machine combines unit.
Background technique
The heat that friction generates when single screw rod feeder works is larger, and shearing suffered by material is also uneven, conveying capacity
Smaller, extrusion output is lower, and speed of production is slow, low efficiency；Material residence time in barrel is short, and mixing is uneven, produces
Plastic pellet inferior quality.
Utility model content
In order to overcome the disadvantages mentioned above of the prior art, stable, work that the purpose of the utility model is to provide a kind of extrusion outputs
The efficient feeding of the high twin-screw extrusion testing machine of product quality that is high-efficient, producing combines unit.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of efficient feeding combination unit of twin-screw extrusion testing machine, including feeding device, drawing-in device and vacuum means
It sets, in which:
The drawing-in device includes feedstock barrel, the twin-screw in feedstock barrel and the driving machine with twin-screw transmission connection
Structure, the driving mechanism include feeding motor and gear reduction box, and the feeding motor is connected by gear reduction box and twin-screw
It connects；
The feeding device include set on the broach hopper on feedstock barrel top, the screw agitation shaft in broach hopper and
With the stirring motor of screw agitation shaft transmission connection；
The vacuum evacuation device includes the exhaust outlet being set on feedstock barrel, the exhaust pipe and and exhaust pipe that connect with exhaust outlet
The vacuum pump of connection, the exhaust pipe are equipped with pressure gauge and barometric damper.
As further improvement of the utility model: the twin-screw is meshed double screw in the same direction.
As further improvement of the utility model: being welded with multiple rotations in the screw agitation shaft in a spiral shape
Blade.
As further improvement of the utility model: the top of the broach hopper is equipped with top cover, and the top cover is equipped with
Transparent observation window.
Compared with prior art, the utility model has the beneficial effects that
The heat that the utility model friction generates is less, and also more uniform, twin-screw conveying energy is sheared suffered by material
Power is larger, and extrusion output is more stable, and work efficiency is high, while material residence time in feedstock barrel is longer, is uniformly mixed, production
Product quality out is higher.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Now in conjunction with Detailed description of the invention, the present invention will be further described with embodiment:
According to Fig. 1, a kind of efficient feeding of twin-screw extrusion testing machine combines unit, including feeding device, feeding dress
It sets and vacuum evacuation device, in which:
The drawing-in device includes feedstock barrel 21, the twin-screw 22 in feedstock barrel 21 and is sequentially connected with twin-screw 22
Driving mechanism, the driving mechanism includes feeding motor 24 and gear reduction box 23, and the feeding motor 24 is subtracted by gear
Fast case 23 is connect with twin-screw 22；
The feeding device includes broach hopper 11, the spiral shell in broach hopper 11 set on 21 top of feedstock barrel
The stirring motor 13 for revolving agitating shaft 12 and being sequentially connected with screw agitation shaft 12；
The vacuum evacuation device includes the exhaust outlet 31 being set on the feedstock barrel 21, the exhaust pipe connecting with exhaust outlet 31
32 and the vacuum pump 33 that is connect with exhaust pipe 32, the exhaust pipe 32 be equipped with pressure gauge 34 and barometric damper 35.
The twin-screw 22 is meshed double screw in the same direction.
It is welded with multiple rotating vanes in a spiral shape in the screw agitation shaft 12.
The top of the broach hopper 11 is equipped with top cover 14, and the top cover 14 is equipped with transparent observation window.
Between the feeding device and drawing-in device be equipped with a connection structure, the connection structure feed end connection described in
The discharge port of feeding device, the discharge end of the connection structure connect the feed inlet of the drawing-in device, set in the connection structure
There is feeding-passage 42, the installation step 41 for fixing feeding device is equipped in the feed end of the connection structure, in the connection knot
The discharge end of structure is equipped with the fixation step 43 for connecting drawing-in device.The generally up-small and down-big structure of the connection structure, energy
It is adapted the discharge port of feeding device with the feed inlet of drawing-in device, plays the role of dredging material, material accumulation is avoided to exist
The discharge port of feeding device causes discharge port to block, and increases the charging ability of feeding device, improves the feeding of drawing-in device
Amount, to further improve the production production capacity and production efficiency of drawing-in device.
In conclusion after those skilled in the art read the utility model file, skill according to the present utility model
Art scheme and technical concept are not necessarily to creative mental labour and make other various corresponding conversion schemes, and it is practical new to belong to this
The range that type is protected.
