Abstract

The utility model relates to a vertical extruder, wherein, a charging barrel and a screw are arranged vertically; the lower end of the charging barrel is fixed above a stander by a connecting piece; the upper end of the screw is provided with an enforced feeder and the lower part of the screw is also provided with a sealing device; the lower end of the screw passes through the stander to be connected with the speed reducer arranged under the stander; the feeding hopper is sheathed on the outside of the upper end of the screw and is fixedly connected with the upper end of the charging barrel; the inner wall of the feeding hopper is provided with a flowing guide plate and the inner wall of the charging barrel arranged on the lower part of the feeding hopper is provided with a flowing guide groove corresponding to the flowing guide plate. The utility model has simple structure; the charging barrel and the screw are arranged vertically, when the material is fully filled in a spiral flute, the friction and abrasion between the charging barrel and the screw are reduced, thus prolonging the service life of the extruder; the feeding hopper and the charging barrel are arranged coaxially, so that the material-taking angle is large and the feeding efficiency is high; the transmission power part and the torque bearing part are the largest diameter part of the screw, so that the screw does not break easily; the screw can be made of common steel, thus having lower manufacturing cost and long service life.

Description

Vertical extruder

Technical field

The utility model relates to a kind of extruder that uses in the plastics-production industry, specifically a kind of vertical extruder.

Background technology

The extruder that is used to produce plastics at present mostly is horizontal extruder.There is following defective in this type of extruder:

1, the barrel and the screw rod horizontal positioned of existing extruder, the extruding end of its screw rod does not have support, is turning round under hot environment for a long time, the screw rod end sinks, screw rod and barrel rub, and screw thread and material tube inner wall on the screw rod are worn, and barrel is eccentric to be scrapped owing to the wearing and tearing of barrel internal diameter cause;

2, the screw rod of existing extruder is that the driving end diameter is less than the extruding end diameter, when material fills up screw channel, under the effect of powerful moment of torsion, the driving end of screw rod ruptures easily, service life is short, and the screw rod of some extruder adopts high temperature resistant, anti-abrasive material, improves cost of manufacture.

3, install vertical with barrel of hopper of existing horizontal extruder limited the feed angle when reinforced, makes material be difficult for being full of screw channel, reinforced inefficiency.

Summary of the invention

The utility model is at the deficiency of existing horizontal extruder, provides a kind of simple in structure, the vertical extruder of long service life.

Realize the foregoing invention purpose by the following technical solutions: a kind of vertical extruder, comprise barrel, place screw rod, material bin, frame, reductor and the motor of barrel inside, described barrel and screw rod are vertically placed, the barrel lower end is fixed on the frame top with connector, the forced feeding device is equipped with in the screw rod upper end, on this forced feeding device the eddy flow plate is housed also, a sealing device also is equipped with in this screw rod bottom, the screw rod lower end is passed frame and is connected with the reductor that places the frame below, and reductor is connected with the motor of frame outside; Described material bin is sleeved on the outside of screw rod upper end, and is fixed in the barrel upper end, and this material bin inwall is provided with deflector, and the material tube inner wall of material bin bottom is provided with and the corresponding guiding gutter of deflector.

Compare with existing horizontal extruder, the beneficial effects of the utility model are:

1, simple in structure, barrel and screw rod are vertically placed, and when material is full of screw channel, reduce the friction and wear between the two, prolong the service life of extruder;

2, the material bin of this vertical extruder and the coaxial setting of barrel, it is big to get the material angle, reinforced efficient height, material can be full of screw channel fully, and cost of manufacture is low, and production efficiency height, output are big, and processing plastic is wide in variety, enlarges production range;

3, the transfer motion power of this vertical extruder and to bear moment of torsion partly be the screw diameter maximum, it is big to bear moment of torsion, and screw rod is easy fracture not, and screw rod can adopt common iron to make, and cost of manufacture is low, long service life.

Description of drawings

Fig. 1 is an overall structure schematic diagram of the present utility model.

Fig. 2 be among Fig. 1 A to the partial structurtes schematic diagram.

Among the figure: material bin 1, deflector 2, eddy flow plate 3, guiding gutter 4, screw thread 5, screw rod 6, heater 7, barrel 8, sealing gasket 9, adapter sleeve 10, frame 11, reductor 12, motor 13, discharging opening 14, forced feeding device 15.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Referring to accompanying drawing, in the present embodiment, the barrel 8 of this vertical extruder and be positioned at its inner screw rod 6 and vertically place, the lower end of barrel 8 is fixed by bolts to the top of frame 11, screw rod 6 surfaces are provided with screw thread 5, its top also is connected with a dismountable forced feeding device 15 by screw thread, on this forced feeding device 15 eddy flow plate 3 is housed.6 times thick going up carefully of screw rod, its lower end is passed frame 11 tops and is connected with the reductor 12 that places frame 11 belows, this reductor 12 is connected with the motor 13 of frame 11 outsides, and the two junction also is socketed with an adapter sleeve 10, and this adapter sleeve 10 can guarantee the concentricity of screw rod 6 and power transmission shaft.

Described material bin 1 is welded on the upper end of barrel 8, be welded with six groups of deflectors 2 on the inwall of this material bin 1, per two deflectors 2 are one group, form groove shape structure, on the inwall of the barrel 8 of material bin 1 bottom, also be provided with six and deflector 2 corresponding guiding gutters 4, discharging opening 14 is positioned at a side of barrel 8 bottoms, and three heaters 7 are equipped with in the outside of described barrel 8.

Sealing device described in the present embodiment is made up of a plurality of sealing gaskets 9, the maximum diameter place, bottom of sealing pad 9 socket screw rods 6, and the narrow footpath that promptly is positioned at barrel 8 is located.

Operation principle of the present utility model is:

Open electric heater 7, give barrel 8 heating, after barrel 8 reaches assigned temperature, open motor 13 and reductor 12, its power transmission shaft drives screw rod 6 and rotates, and doses material in material bin 1, the material that some are difficult for entering, force down to enter by the rotation stirring of eddy flow plate 3 and the cooperation of deflector 4, tiny material enters barrel 8 along deflector 2 by guiding gutter 4, and material melts rapidly in hot environment, stirring extruding at screw thread 5 is depressed, and is extruded by discharging opening 14 at last.

The diameter maximum of screw rod 6 is connected with the power transmission shaft of reductor 12, increases the moment of torsion holding capacity, screw rod 6 long service life.After material fills up screw channel, can avoid rocking of screw rod 6, and reduce the friction of screw rod 6 and barrel 8.Material bin 1 and barrel 8 coaxial communication increase the feed angle greatly.In the process of pressing materials, because screw rod 6 imposes on downward spin of material, and the reaction force that material can make progress for screw rod 6 one equally, cause screw rod 6 upwards to be carried, thereby drive sealing gasket 9 upwards, when sealing gasket 9 is expressed to the narrow footpath of barrel 8, play sealing function, reach sealing effectiveness.
