Abstract
The utility model discloses a plastic extruding machine comprising a feeding device, a driving mechanism, a charging barrel and a vacuum-pumping device, wherein the feeding device comprises a hopper main body at one end of the charging barrel of the extruding machine, and a spiral stirrer in the hopper main body; a top cover is arranged at the top of the hopper main body; a feeding hopper, a motor and a reducer are arranged at the top cover of the hopper main body; a lateral feeding part is arranged between the charging barrel of the extruding machine and the hopper main body; the lateral feeding part comprises a feeding box communicated with the charging barrel of the extruding machine, a feeding screw rod, a feeding motor driving the feeding screw rod, and a reduction gearbox; the feeding screw rod is positioned below the hopper main body; and one end part of the feeding screw rod extends into the feeding box. Through the adoption of the plastic extruding machine with the structure that materials are pre-compacted through the spiral stirrer of the feeding device and then fed into the extruding machine through the feeding screw rod, the materials can be pre-compacted during feeding, so as to avoid the phenomenon of nonuniform material conveying and improve the qualification rate of products.
Description
Technical field
The utility model relates to a kind of plastic extruder.
Background technology
Plastic extruder comprises feeding device, driving mechanism, barrel and vacuum extractor; Feeding device comprises the hopper body and the intrinsic spiral agitator of hopper of extruder barrel one end; The top of hopper body has top cover, has feeding hopper, motor and decelerator on the top cover of hopper body, and existing feeding device adopts the reinforced hopper of gravity fall; Maintain certain controlling level in the hopper, above machine barrel charging aperture below the hopper, all pile with material.When the screw rod in the barrel rotated, the spiral shell rib of screw rod was taken away material by machine barrel charge door below, and material leans on the screw channel that rotates into of gravity and screw rod.The mode that the gravity factor of this employing material own is reinforced; Reinforced situation and material level height also have relation; Because the height of materials in the hopper is a continually varying, this just can cause feed end pressure also can produce slight variation, and influences the conveying capacity of material; Cause the inhomogeneous even termination of charging, product percent of pass reduces.
The utility model content
The utility model technical problem to be solved is: a kind of plastic extruder is provided, and this kind plastic extruder can avoid the mass transport uneven phenomenon to take place, and can improve product percent of pass.
Solve this technical problem; The technical scheme of the utility model is: a kind of plastic extruder; Comprise feeding device, driving mechanism, barrel and vacuum extractor; Described feeding device comprises the hopper body and the intrinsic spiral agitator of hopper of extruder barrel one end, and the top of hopper body has top cover, has feeding hopper, motor and decelerator on the top cover of hopper body; Be provided with side feeding portion between described extruder barrel and the hopper body; Described side feeding portion comprises the feeding motor and the reduction box of the material feeding box that communicates with extruder barrel, feed screw, driving feed screw, and described feed screw is positioned at the below of hopper body, and the end of feed screw feeds material feeding box.
Described feed screw is the level of state.
Described material feeding box and extruder barrel removably connect.
A kind of plastic extruder of the utility model adopts such structure; The spiral agitator of feeding device carries out material to be discharged in the extruder through feed screw after the pre-compacted; When reinforced, can carry out pre-compacted to material; Avoid the uneven phenomenon of mass transport to take place, thereby improved product percent of pass.And feeding quantity can control through the rotating speed of regulating feed screw, and material part in screw channel is full of, and material compress and the melting process hysteresis in screw rod, and the reduction melt temperature is controlled extrusion better.

The specific embodiment
Like Fig. 1, shown in Figure 2; Plastic extruder comprises feeding device 6, driving mechanism 7, barrel 5 and vacuum extractor; Feeding device comprises the hopper body 16 of extruder barrel 22 1 ends, spiral agitator 17, motor 13, decelerator 14, feeding hopper 15 and the side feeding portion in the hopper body 16, and the top of hopper body 16 has top cover, has feeding hopper 15, motor 13 and decelerator 14 on the top cover of hopper body 16; Side feeding portion is arranged between extruder barrel 22 and the hopper body 16; Side feeding portion comprises material feeding box 21, the feed screw 20 that communicates with extruder barrel 22, feeding motor 18 and the reduction box 19 that drives feed screw 20, and feed screw 20 is positioned at the below of hopper body 16, and the end of feed screw 20 feeds material feeding box 21; Feed screw 20 is the level of state, and material feeding box 21 removably connects with extruder barrel 22.
Vacuum extractor comprises exhaust outlet 4, Pressure gauge 3, barometric damper 2, vavuum pump 8, volume separator 10, downtake pipe 1 and the second exhaust pipe 9 on the barrel 5; Has water-filled volume separator 10 between exhaust outlet 4 and the vavuum pump 8; Volume separator 10 sidewalls have water inlet 11 and delivery port 12; Has the downtake pipe 1 that is communicated with between volume separator 10 and the exhaust outlet 4; Have the second exhaust pipe 9 that is communicated with between volume separator 10 and the vavuum pump 8, Pressure gauge 3 is arranged on the downtake pipe 1 with barometric damper 2.Downtake pipe 1 removably connects with exhaust outlet 4, and second exhaust pipe 9 removably connects with vavuum pump 8.
Such structure, raw material add from feeding hopper, through the rotation of spiral agitator; After material is compacted along the hand of spiral; Again through the feed screw feeding in extruder, can avoid some material to be difficult to feed in raw material, form the phenomenon of " bridge formation ", when reinforced, can carry out pre-compacted to material; Avoid the uneven phenomenon of mass transport to take place, thereby improved product percent of pass.And feeding quantity can control through the rotating speed of regulating feed screw, and material part in screw channel is full of, and material compress and the melting process hysteresis in screw rod, and the reduction melt temperature is controlled extrusion better.
