Abstract
The utility model discloses a die head of a plastic extruder and belongs to the technical field of plastic machine manufacture. The die head comprises a die head main body, wherein the die head main body is fixedly connected with the tail end of a heating unit of the plastic extruder, and a plastic passage is arranged in the die head main body; a forming mold plate is mounted at the outlet end of the plastic passage; a filter screen replacing plate is horizontally arranged in the die head main body in a position corresponding to the plastic passage and can be moved out of the die head main body through a cylinder; filter screens are arranged on the filter screen replacing plate; a plurality of heating pipes facing the same direction as the plastic passage are arranged between the filter screen replacing plate and the heating unit in the die head main body; a pressure sensor is arranged in the plastic passage and between the filter screen replacing plate and the heating unit; the pressure sensor is connected with a controller; the controller is connected with the cylinder through an electromagnetic valve. According to the die head of the plastic extruder, the problems that the performance of modified plastic products is affected by non-uniform temperature of the conventional die head of the plastic extruder in the manufacturing process and the filter screens cannot be replaced in time after being blocked are solved.
Description
Technical field
The utility model relates to plastics machinery manufacturing technology field, especially a kind of die head of plastic extruding machine.
Background technology
At present in the production of modified plastic material, its production method is that various plastic raw materials are fully mixed to melting on the heating unit that is input to plastic extruder, raw material after melting is configured as strip by die head of plastic extruding machine by the modified plastics of melting, cuts off and becomes particulate material for follow-up equipment; In the production of this modified plastic material, have impurity, or there is no the infusibility raw material of enough pulverizing.Existing a kind of die head of plastic extruding machine includes its inside affixed with extruder heating unit tail end and offers the die body of plastic of conduit, plastic of conduit import is connected with the outlet of extruder heating unit, the plastic of conduit port of export is provided with forming panel, be horizontally arranged with and can shift out by cylinder the screen replacing plate of die body inside with respect to plastic of conduit in die body inside, on screen replacing plate, filter screen is installed, in production, this die head of plastic extruding machine can produce following problem: 1, because die head of plastic extruding machine temperature is lower than plastic extruder heating unit temperature, and modified plastics is to be mixed by various different types of plastic raw materials, temperature can produce different impacts to the performance of different types of plastics, so can affect modified plastics end properties.2, cause melt flow variation because the low meeting of die head of plastic extruding machine temperature causes the decline of solution temperature, easily cause the obstruction of filter screen.3, need manual observation could determine whether the filter screen of die head stops up and start cylinder and carry out the replacing of filter screen, if change not in time filter screen in production and just easily cause the breaking-up of machine, thereby impact is produced.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of die head of plastic extruding machine, this die head of plastic extruding machine can solve existing die head of plastic extruding machine in process of production non-uniform temperature affect and can not get the problem changed in time after modified plastics end properties and filter net jam.
In order to address the above problem, the technical scheme that the utility model adopts is: include its inside affixed with plastic extruder heating unit tail end and offer the die body of plastic of conduit, the described plastic of conduit port of export is provided with forming panel; In described die body, be horizontally arranged with and can shift out the screen replacing plate in described die body by cylinder with respect to described plastic of conduit, on described screen replacing plate, filter screen is installed, in the described die body between described screen replacing plate and described heating unit, be provided with many with described plastic of conduit towards identical heating tube; In described plastic of conduit between described screen replacing plate and described heating unit, be provided with pressure sensor, described pressure sensor is connected with controller, and described controller is connected with described cylinder by magnetic valve.
In above-mentioned die head of plastic extruding machine technical scheme, technical scheme can also be more specifically: described heating tube is connected with the heating controller of described plastic extruder.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:
1, in the die body of the utility model between extruder heating unit and screen replacing plate, arrange many with plastic of conduit towards identical heating tube, the temperature of die body and the temperature of plastic extruder heating unit are consistent, not only ensure modified plastics end properties, also made solution have better mobility to be difficult for causing the obstruction of filter screen.
2, in the plastic of conduit between extruder heating unit and screen replacing plate, be provided with pressure sensor, when the bulk materials such as impurity obstruction amount in die head filter screen larger, extruding is obstructed while making in plastic of conduit pressure increase, pressure sensor is that transmission of pressure signal is to controller, the signal of controller output moves by solenoid control cylinder, thereby drive screen replacing plate to be displaced to outside die body, filter screen is changed in time, improved the security reliability of producing.
brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail:
Die head of plastic extruding machine shown in Fig. 1, includes its inside affixed with extruder heating unit tail end and offers the die body 1 of plastic of conduit, and plastic of conduit import 1a is connected with heating unit outlet, and plastic of conduit outlet 1b end is provided with forming panel 7; Be horizontally arranged with screen replacing plate 5 in die body 1 inside with respect to plastic of conduit, screen replacing plate 5 one end are fixedly connected with the telescopic arm of cylinder 6, the inside that cylinder 6 is stretched or screen replacing plate 5 can shift out by cylinder 6 die body 1 when contracting, filter screen 4 is installed on screen replacing plate 5, in die body 1 between screen replacing plate 5 and heating unit, be provided with many with plastic of conduit towards identical heating tube 3, heating tube 3 is connected with the heating controller of plastic extruder; In plastic of conduit between screen replacing plate 5 and heating unit, be provided with pressure sensor 2, pressure sensor 2 is connected with controller, and controller is connected with cylinder 6 by magnetic valve; Pressure sensor 2 induction pressure signals are exported to controller, and controller is stretched or contracted by solenoid control cylinder 6.
In the time that plastic extruder is worked, heating controller by plastic extruder heats heating unit and die head of plastic extruding machine simultaneously, the temperature of die body 1 and the temperature of plastic extruder heating unit are consistent, not only ensure modified plastics end properties, also made solution have better mobility to be difficult for causing the obstruction of filter screen 4.When the bulk materials such as impurity obstruction amount in die head filter screen 4 larger, extruding is obstructed while making in plastic of conduit pressure increase, pressure sensor 2 is that transmission of pressure signal is to controller, controller moves by solenoid control cylinder 6, thereby drive screen replacing plate 5 to be displaced to outside die body 1, filter screen 4 is changed in time, improved the security reliability of producing.
