Abstract
The utility model discloses a cylinder of a plastic extruder and relates to the technical field of plastic extruder manufacture. The cylinder comprises a plurality of cylinder bodies with cavities communicated in sequence, wherein the cavities form a plastic extruding passage; a plurality of heating pipes are horizontally arranged in the cylinder bodies in positions corresponding to the plastic extruding passage; the two ends of each heating pipe are respectively communicated with the oil outlet and the oil inlet of a heating oil station through oil pipes, two or more temperature sensors connected with a controller are arranged in the cylinder bodies. Compared with the prior art, the heating pipes made of copper are arranged in the cylinder bodies and the cylinder bodies are heated with thermal oil, so that the heating efficiency is greatly improved, and energy is saved by 25 percent when compared with cylinder bodies adopting an electrothermal film heating mode.
Description
Technical field
The utility model relates to plastic extruder manufacturing technology field, especially a kind of machine barrel for double-screw plastic extrusion machine.
Background technology
Double-screw plastic extrusion machine machine barrel is one of important parts of double-screw plastic extrusion machine, its operation principle is that various plastic raw materials are fully mixed and on the machine barrel that is input to plastic extruder, carry out heating and melting, raw material after melting is configured as strip by plastic extruder die head by the modified plastics of melting, cuts off and becomes particulate material for follow-up equipment.The plastic extruder of existing a kind of twin-screw, this machine barrel has multiple cylindrical shells that its chamber is connected successively, in each described cylindrical shell outer wrap one deck Electric radiant Heating Film.In use there are the following problems for this plastic extruder: 1, owing to being to be undertaken by the outside Electric radiant Heating Film of parcel cylindrical shell the heating of machine barrel, although be provided with insulation heat preservation layer outward in Electric radiant Heating Film, but still have a large amount of heat energy not to be fully used, cause that the heat time is long, energy consumption is high; 2, cannot regulate according to raw materials for production the heating-up temperature of machine barrel.
Utility model content
The problem that the utility model solves is to provide one can carry out thermoregulator plastic extruder, to solve cylindrical shell heat time length and the high problem of energy consumption of existing plastic extruder.
In order to address the above problem, the technical solution adopted in the utility model is: this plastic extruder includes multiple cylindrical shells that chamber is connected successively, these described chambers that are connected form a plastic extrusion passage, in described cylindrical shell, be horizontally arranged with many two ends with respect to described plastic extrusion passage and stretch out respectively the heating tube of its two sides, the two ends of described heating tube are connected with oil-out and the oil return opening of heating petrol station by oil pipe respectively; Described in these, on cylindrical shell, be at least provided with two temperature sensors that are connected with controller.
In above-mentioned plastic extruder technical scheme, technical scheme can also be more specifically: many described heating tubes are set in parallel, and described heating tube is copper pipe.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect: 1, owing to being provided with at the upper and lower cylindrical shell of plastic extrusion passage the heating tube that material is copper pipe, adopt conduction oil to heat cylindrical shell, greatly improve the efficiency of heating surface, adopted heated by electrothermal film energy-conservation 25% than cylindrical shell; 2,, owing to being provided with temperature sensor on cylindrical shell, can regulate according to raw material the heating-up temperature of cylindrical shell.

Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail:
Plastic extruder as shown in Figure 1, Figure 2 and Figure 3 includes four cylindrical shells 1 that chamber 6 is connected successively, between cylindrical shell 1 and cylindrical shell 1, is bolted; The chamber being connected successively 6 of these cylindrical shells 1 forms a plastic extrusion passage, is coated with two intermeshing screw rods that are connected with drive unit in plastic extrusion passage; In cylindrical shell 1, be horizontally arranged with many two ends with respect to plastic extrusion passage and stretch out respectively the heating tube 2 of its two sides, many heating tubes are set in parallel and are installed on abluminal compartment 6 places on cylindrical shell 1 top and abluminal compartment 6 places of cylindrical shell 1 bottom, two ends at every heating tube 2 are all connected with pipe joint 2-1, one end of heating tube 2 is connected with the oil-out of heating petrol station 5 by the oil pipe being connected with pipe joint 2-1, the other end of heating tube 2 is connected with oil return opening by the oil pipe that is connected with pipe joint 2-1 and heating petrol station 5, and the heating tube 2 of the present embodiment is copper pipe; Because the material heating tube that is copper pipe is distributed in abluminal compartment 6 places of cylindrical shell 1, while adopting conduction oil to heat cylindrical shell 1, can greatly improve the efficiency of heating surface; On first cylindrical shell 1 of these four cylindrical shell 1 front ends and the 4th cylindrical shell 1 of end, be separately installed with two temperature sensors 3 that are connected with controller 4, the temp probe of temperature sensor 3 is contained on cylindrical shell 1 by probe mount pad.
When work, controller 4 is controlled from the conduction oil that flows out of heating petrol station 5 cylindrical shell 1 is heated, and makes cylindrical shell 1 to from being squeezed through the plastic raw materials of plastic extrusion passage and carry out heating and melting by two intermeshing screw rods; On cylindrical shell 1, temperature sensor is housed, controller 4 can regulate by controlling the temperature of the conduction oil of exporting at deep fat station 5 heating-up temperature of cylindrical shell 1.
Claims (2)
1. a plastic extruder, include multiple cylindrical shells (1) that chamber (6) is connected successively, the described chamber (6) that these are connected forms a plastic extrusion passage, it is characterized in that: in described cylindrical shell (1), be horizontally arranged with many two ends with respect to described plastic extrusion passage and stretch out respectively the heating tube of its two sides (2), the two ends of described heating tube (2) are connected with oil-out and the oil return opening of heating petrol station (5) by oil pipe respectively; Cylindrical shell described in these (1) is provided with the temperature sensor (3) being connected with controller (4).
