Abstract
The utility model discloses a kind of constant-current stabilizer of extruder, comprising: be connected with the current stabilization body 5 identical with lower screw rod 4-1 inside radius extruding between duckbilled 4-2 and extruder 3.Being achieved by the utility model adopts current stabilization body 5 to the stability contorting being sent to the plasticity material block flow extruding duckbilled 4-2; Further, realize cooling being sent to the plasticity material block extruding duckbilled 4-2 by cooling chamber 5-1, favourable sheet material forming.
Description
Technical field
The application relates to extrusion machinery technical field, espespecially a kind of constant-current stabilizer of extruder.
Background technology
When extruder is applied to the sheet material of fibre cement, complete whole manufacturing process: first mainly through following steps, the requirement of the formula formulated according to sheet properties by the various raw materials making sheet material is configured; Then fully stirred by mixer, and make through kneader, mixing roll the plasticity material block all made; Finally add in extruder, by extruder, air discharge and the control of extruding output flow etc. are carried out to plasticity material block and realize the process shaping to board making.
Fig. 1 is the overall structure block diagram of existing extruder, and as shown in Figure 1, extruder, from the processing procedure being fed to extrusion molding, structurally mainly comprises: upper screw rod 1, vacuum storehouse 2, lower screw rod 4-1 and die head mould extrude duckbilled 4-2 and mould part.After plasticity material block drops into from charging aperture, vacuum storehouse 2 is entered into through upper screw rod 1, vacuum storehouse 2 set pressure under (generally at below-0.08MPa) carry out air discharge, that discharges that the plasticity material block of air is further advanced to the die head mould of extruder by lower screw rod 4-1 extrudes in duckbilled 4-2 and mould, arranged by the flow-control of the diverse location to mould and the shape of mould, form the sheet material of different cross section shape.
Formed in sheet material process at extruder, lower screw rod 4-1 and to extrude the spacing of duckbilled 4-2 less, in use there are wearing and tearing in screw rod 3 instantly, then extruding the flow that duckbilled 4-2 squeezes toward mould will change, and affects the percent defective of sheet forming.
Summary of the invention
In order to solve the problem, the utility model provides a kind of constant-current stabilizer of extruder, can steady extruding duckbilled extrude flow.
In order to reach the purpose of this utility model, the application provides a kind of constant-current stabilizer of extruder, comprising:
Be connected with the current stabilization body (5) identical with lower screw rod (4-1) inside radius extruding between duckbilled (4-2) and extruder (3).
Further, the length of current stabilization body (5) is 260 millimeters.
Further, current stabilization body (5) also includes the cooling chamber (5-1) risen for reducing, the temperature that causes of being rubbed by plasticity material block and extruder (3) and current stabilization body (4) be arranged at outside output channel, and cooling chamber includes cooling water I/O channel.
The utility model provides a kind of technical scheme, comprising: be connected with the current stabilization body 5 identical with lower screw rod 4-1 inside radius extruding between duckbilled 4-2 and mould.Being achieved by the utility model adopts current stabilization body 5 to the stability contorting being sent to the plasticity material block flow extruding duckbilled 4-2; Further, realize cooling being sent to the plasticity material block extruding duckbilled 4-2 by cooling chamber 5-1, favourable sheet material forming.
Accompanying drawing explanation
Accompanying drawing is used to provide the further understanding to technical scheme, and forms a part for description, is used from the technical scheme explaining the application, does not form the restriction to technical scheme with the embodiment one of the application.
Fig. 1 is the overall structure block diagram of existing extruder;
Fig. 2 is the structured flowchart of screw rod under the utility model.
Detailed description of the invention
For making the object of the application, technical scheme and advantage clearly understand, hereinafter will by reference to the accompanying drawings the embodiment of the application be described in detail.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can be combined mutually.
Fig. 2 is the structured flowchart of screw rod under the utility model, as shown in Figure 2, comprising: be connected with the current stabilization body 5 identical with lower screw rod 4-1 inside radius extruding between duckbilled 4-2 and mould.
It should be noted that, because wearing and tearing in use appear in existing lower screw rod 4-1, the flow that duckbilled 4-2 squeezes past mould is extruded in impact, and by the setting of current stabilization body 5, what can make plastic material extrudes stability of flow.Here the connected mode of current stabilization body 5 can be realized by existing connected mode, as long as the steadiness that can meet connection requires, preferably, can adopt screw rod 1 and vacuum storehouse 2 or the connected mode between vacuum storehouse 2 and extruder 3 on extruder.
Preferably, the length of current stabilization body 5 is 260 millimeters.
Current stabilization body 5 also includes the cooling chamber 5-1 risen for reducing, the temperature that causes of being rubbed by plasticity material block and extruder 3 and current stabilization body 4 be arranged at outside output channel, and cooling chamber includes cooling water I/O channel.
It should be noted that, cooling chamber is for reducing when extruder works, and the inwall of extruder 3 and current stabilization body 4 and plasticity material block produce and rub, and causes plasticity material block, current stabilization body 4 and extrudes duckbilled 4-2 temperature and rise, affect extruder work.The design of cooling chamber is relevant with the friction size of extruder 3 and current stabilization body 4 with plasticity material block, according to temperature design requirement, those skilled in the art design in conjunction with the size of cooling chamber and the speed etc. of cooling water input and output, belong to the conventional techniques means of those skilled in the art, do not repeat them here.
Although the embodiment disclosed by the application is as above, the embodiment that described content only adopts for ease of understanding the application, and be not used to limit the application.Those of skill in the art belonging to any the application; under the prerequisite not departing from the spirit and scope disclosed by the application; any amendment and change can be carried out in the form implemented and details; but the scope of patent protection of the application, the scope that still must define with appending claims is as the criterion.
Claims (2)
