Abstract
The utility model relates to a plastic extruding machine which belongs to the technical field of plastic processing machinery. The utility model is designed in order to conveniently change a screw rod. The utility model comprises a heat source, a hopper (1), a material pipe (2) and a die head (3), wherein the die head (3) is arranged at the outlet end of the material pipe (2), a screw rod (4) is arranged in the material pipe. One end of the screw rod, which is adjacent to the hopper, is mutually fixed with a driving gear and the screw rod is connected to a motor through a transmission mechanism containing the driving gear. The utility model is characterized in that the end part of one end, which is aligned to the screw rod and is adjacent to the hopper, is fixedly provided with an oil cylinder (5) communicated with an oil pump through a control device. The utility model adopts an upright type gear wheel box (9) to fit to the height which is required by the screw rod, the pad height is cancelled or reduced and the weight is reduced. A gear wheel shaft hole of the gear wheel box (9) is arranged in the boundary surface position of a box body and a box cover, the shaft hole is formed by combining the box body with the box cover and the gear wheel box is assembled and disassembled conveniently.
Description
Affiliated technical field
The utility model belongs to technical field of plastic processing machinery, relates in particular to the plastic extruder of plastic granulator system.
Background technology
Industry said " plastic granulator machine ", the system that forms by the subsidiary hygroscopic machine of (minimum comprising) plastic extruder, bosh, three equipment of pelleter.The function of plastic extruder is with the plastic cement fusing and by the screw rod extrusion device it to be extruded from die head to make plastic cement be the section strip fixed according to die head.Under situations such as change raw material, need to change or clean the screw rod of plastic extruder.Because the output gear of its screw rod and gear-box installs with core, add in the feeding tube with on the screw rod and also have a little plastic cement, resistance is very big, and beaing by manpower need about 30 minute, perhaps pushes screw rod with what the manpower turn was established specially in addition, also wants 15 minutes.Not only incured loss through delay these times, and machine also there is cooling significantly after more finishing changing screw rod, need reheat intensification, both expends time in, and also expends the more energy.
Summary of the invention
For solve existing plastic extruder not only consuming time when changing screw rod, but also expend the problem of the energy, the utility model provides a kind of plastic extruder, it is laborsaving, convenient that its changes screw rod, quick.
The technical scheme that is adopted is: aim at the ad hoc oil cylinder in end of screw rod, start oil pump and give oil cylinder with power in needs, by oil cylinder screw rod is released.That is:
A kind of plastic extruder comprises thermal source, hopper, material pipe, die head, and die head is installed in the port of export of material pipe, installing screw rod in the material pipe, and screw rod is connected to motor near end of hopper and the transmission mechanism that driven wheel installs and process comprises this driven wheel; It is characterized in that: aim at the end of screw rod, (the being communicated to oil pump) oil cylinder that installs through control device near an end of hopper.
The beneficial effects of the utility model: through prototype experiment, artificial down auxiliary, the utility model is as long as just can finish the work of changing screw rod in 2,3 minutes.Saved the time, manpower, also saved the energy.
Description of drawings
Introduce the utility model in detail below in conjunction with accompanying drawing:
Fig. 1 is a schematic diagram of the present utility model.
The specific embodiment
As shown in the figure, a kind of plastic extruder, comprise thermal source, hopper 1, material pipe 2, die head 3, die head 3 is installed in the port of export of material pipe 2, installing screw rod 4 in the material pipe, screw rod near an end of hopper be installed in driven wheel in the gear-box 9 and install mutually and be connected to motor through the transmission mechanism that comprises this driven wheel; It is characterized in that: aim at the end of screw rod, install the oil cylinder 5 that one (through control device) is communicated to oil pump (being to illustrate among the figure) near hopper one end.
" (through control device) is communicated to the oil cylinder 5 of oil pump " herein can be carried out equivalence with other linear reciprocating mechanism and be replaced, such as using " (through control device) is communicated to the straight line cylinder of high-pressure air source ".
Installing mutually of screw rod and driven wheel is enclosed within screw rod in the axis hole of its driven wheel and the keyway that both aim at this is embedded in fastening key and realizes.To dismantle fastening key earlier during dismounting.
As shown in the figure, the gear-box 9 that the utility model also adopts vertical (being that each gear shaft is arranged up and down) to be to adapt to the needed height of screw rod, cancels or reduces (adopt usually horizontal gear-box needed) bed hedgehopping, reduces weight.And the gear axis hole of (not shown) gear-box 9 is arranged on the interface place of casing and case lid, and (" casing " and " case lid " has been symmetry substantially from the body at that time, practise title for explaining convenient still continuing to use), be casing and the amalgamation of case lid two-phase and form axis hole, make the mounting or dismounting of gear-box convenient.
Claims (2)
1. plastic extruder, comprise thermal source, hopper (1), material pipe (2), die head (3), die head (3) is installed in the port of export of material pipe (2), installing screw rod (4) in material is managed, screw rod installs near an end of the hopper driven wheel interior with being installed in gear-box (9) and is connected to motor through the transmission mechanism that comprises this driven wheel; It is characterized in that: aim at the end of screw rod, install an oil cylinder (5) that is communicated to oil pump near an end of hopper.
2. plastic extruder according to claim 1 is characterized in that: its gear-box (9) is vertical, and the gear axis hole of gear-box (9) is arranged on the interface place of casing and case lid.
