Specific embodiment

The utility model is described in further detail below in conjunction with attached drawing.

Embodiment 1:

A kind of feeding device of extruder, such as Fig. 1, including hopper 1, horizontal feed conveyor pipe 2 that 1 discharge port of hopper is set, The spiral conveying bar 21(such as Fig. 4 being rotatably arranged in conveying pipeline 2), conveying pipeline 2 is closed at one end open at one end, and conveying pipeline 2 is by solid It is scheduled on the driving of first motor 22 that conveying pipeline 2 closes one end, conveying pipeline 2 is perpendicular equipped with what is be connected to conveying pipeline 2 far from 1 one end of hopper Straight mixing tube 3, such as Fig. 4, the interior rotation of mixing tube 3 is equipped with vertical spiral mixing bar 31, i.e. 31 outer wall of mixing bar has external screw thread Blade, the upper end closed of mixing tube 3, lower end are discharge port, and the upper end of mixing tube 3, the other end are extended in one end of mixing bar 31 The discharge port of mixing tube 3, the feed inlet of 3 lower end discharge port face extruder of mixing tube are extended to, 3 upper end of mixing tube is equipped with driving The actuator 4 that mixing bar 31 rotates.

Such as Fig. 1 and Fig. 3, at this time actuator 4 drive the rotation of mixing bar 31 can further mixed material, improve material into The mixing uniformity for entering extruder improves the quality of product.The opening face of 3 side wall of mixing tube and conveying pipeline 2 is arranged, this When conveying pipeline 2 close to mixing tube 3 one end be equipped with mounting flange 23, mixing tube 3 outside position connect with conveying pipeline 2 consolidate Surely it is arranged with reinforcement block 24, is threaded on mounting flange 23 into the connection bolt 25 in reinforcement block 24, connects bolt 25 have been fixed on reinforcement block 24 on conveying pipeline 2, so that mixing tube 3 and 2 stable connection of conveying pipeline, and reinforcement block 24 is set It sets and reduces material acting in opposition in the power on conveying bar 21 and conveying pipeline 2, reduce the separation of conveying pipeline 2 and mixing tube 3.

Such as Fig. 4, actuator 4 includes the second motor 41 for being horizontally set on 3 upper end of mixing tube, is co-axially located at the second motor The first angular wheel 42 in 41 shafts, the second angular wheel 43 being co-axially located on mixing bar 31, the second angular wheel 43 It is equipped with the first angular wheel 42,3 upper end of mixing tube is covered with outside the first angular wheel 42 and the second angular wheel 43 Protection box 44, the second motor 41 drives the rotation of the first angular wheel 42 at this time, so that the rotation of the second angular wheel 43 is driven, second Angular wheel 43 drives mixing bar 31 to rotate, and protection box 44 protects the first angular wheel 42 and the second angular wheel 43.

Such as Fig. 4, when the first angular wheel 42 and the rotation of the second angular wheel 43, protection box 44, which is equipped with inclination and refuels, to be led to Road 45(such as Fig. 2), protection box 44 is extended in one end of filling passage 45, and the other end extends to the first angular wheel 42 and the second cone The intermeshing top of shape gear 43, filling passage 45 are gradually tilted to the first angular wheel 42 and 43 direction of the second angular wheel Downwards, convenient for the inflow of lubricating oil.

As Fig. 5 needs the last object being detained in mixing tube 3 furthermore when transmitting different material in mixing bar 31 Material is cleaned out, and reduces the mixed influence between different material, therefore be fixed with hollow fixed disk in 3 inner wall upper end of mixing tube 32, the side of fixed disk 32 towards 3 discharge port of mixing tube offers several cleaning eyes 33,3 side of mixing tube be equipped with it is hollow solid Air is passed through in fixed disk 32 by the air inlet pipe 34 that price fixing 32 is connected to, air inlet pipe 34, and passes through cleaning eye 33 to 31 side of mixing bar To air blowing, the material being bonded on mixing bar 31 is cleared up, mixing when reducing next conveying between different material.Such as figure 4, mixing bar 31 is ironwork, and air inlet pipe 34 is equipped with the drying box 35 filled with desiccant, the desiccant pair in drying box 35 It is dried into the air in mixing tube 3, reduces the moisture contained in air and cause getting rusty for mixing bar 31.

Such as Fig. 5, iron rust is generated when transmitting material once mixing bar 31, the 31 outer hand of spiral of mixing bar is equipped with several magnetic Property stirring rod 38, the iron rust being blended in material is attracted on magnetic stirring bar 38 when passing through magnetic stirring bar 38, and magnetic Stirring rod 38 plays stirring action to the mixing of material with the rotation of mixing bar 31, further increases being uniformly mixed for material Property.

Such as Fig. 5, in addition to this in order under the material row that will be bonded on mixing tube 3, therefore during the tube wall of mixing tube 3 is Sky, and mixing tube 3 is equipped with vibrator 36 on the side hollow wall close to mixing bar 31, vibrator 36 will be bonded in when working Material vibrating on 3 inner wall of mixing tube gets off, and reduces materials from bonding in 3 inner wall of mixing tube, and the setting of the hollow tube wall of mixing tube 3 Reduce influence of the ambient temperature to material in mixing tube 3.Puigging 37, sound insulation are filled in hollow position in mixing tube 3 Layer 37 reduces the noise generated when material transmits in mixing tube 3.

Specific operation process: after material is transported in mixing tube 3 out of conveying pipeline 2, material is passed by spiral mixing bar 31 It is defeated, by external screw thread blade on mixing bar 31 stirring and make material mixing it is more uniform, when needing to clear up mixing tube 3, Stop the rotation of the second motor 41, so that the gas in air inlet pipe 34 is by the cleaning eye 33 in fixed disk 32 gradually to mixing bar The blowout of 31 directions, in order to the material for the bonding cleared up on mixing bar 31, while the start-up operation of vibrator 36 will be bonded in mixing Material on pipe 3 is vibrated away from mixing tube 3.

Embodiment 2: a kind of extruder, including above-described embodiment 1.

This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but As long as all by the protection of Patent Law in the scope of the claims of the utility model.
