Abstract
A vacuum degree control device of a polyvinyl chloride (PVC) extruder structurally comprises a machine body, a material barrel is arranged at one end of the machine body, a mold is arranged at the other end of the machine body, and the lower portion of the machine body is connected with a vacuum pump through a negative pressure pipe. A filter layer is arranged at the junction position of the negative pressure pipe and the machine body, material storage boxes are arranged on the negative pressure pipe, the two material storage boxes are arranged in parallel, a valve is arranged on an inlet of each of the two material storage boxes, and a valve is arranged on an outlet of each of the two material storage boxes. The vacuum degree control device of the PVC extruder is provided with the two material storage boxes in parallel, one material storage box is used when the other is under preparation for being used, both the valves of the one material storage box are closed when dust in the one material storage boxes is cleaned, and the other material storage box is used for operation. Therefore, continuity of production is guaranteed, and air can be prevented from entering into materials in the process of cleaning one of the material storage boxes.
Description
Technical field
The utility model relates to a kind of polyvinyl chloride extruder vacuum degree control device, belongs to the equipment for producing plastic products technical field.
Background technology
At the plastic products production industry, most plastic products all are to produce by extruder, the structure of existing extruder such as Figure of description shown in Figure 1, comprise body 1, one end of body 1 is provided with barrel 2, the other end is provided with mould 3, and the below of body 1 is connected with a vavuum pump 6 by negative tube 4; Negative tube 4 is provided with filter course with the junction of body 1, and negative tube 4 is provided with material stock box 5, and material stock box 5 is provided with openable seal cover.During work, material adds body 1 from barrel 2, behind body 1 internal plasticiztion, produces the plastic products of required form through mould 3.In process of production, entrained air produces bubble and causes product defective in the material, and vavuum pump 6 can be with the gas in the material and the sucking-off of impurity dust, and the impurity dust collection is in the 5 interior periodic cleanings of material stock box.
During the dust of the extruder of said structure in cleaning material stock box 5, must allow the extruder break-off, and open in the process that material stock box 5 clears up, air can be sneaked in the material by material stock box 5 again, cause product normally not produce, easily produce the defectives such as bubble, for the problems referred to above, good solution is not also arranged at present.
The utility model content
The purpose of this utility model is to provide a kind of polyvinyl chloride extruder vacuum degree control device, need not to stop to produce during the dust of this device in cleaning material stock box, can avoid also that gas enters material in the scale removal process.
The technical scheme in the invention for solving the technical problem is: polyvinyl chloride extruder vacuum degree control device, comprise body, and an end of body is provided with barrel, and the other end is provided with mould, and the below of body is connected with a vavuum pump by negative tube; The junction of negative tube and body is provided with filter course, and negative tube is provided with the material stock box, and the material stock box is provided with openable seal cover, and described material stock box is set side by side with two, and the import of each material stock box and outlet are respectively arranged with valve.
Described body is provided with a Pressure gauge.
Compared with prior art, the utlity model has following outstanding beneficial effect:
1, is set side by side with two material stock boxes, the import of each material stock box and outlet are respectively arranged with valve, the material stock box can be with one standby one, when clearing up the dust in the material stock box all valves of this material stock box are all closed, the work of another one material stock box, both guarantee the continuity of producing, and can avoid again entering material at cleaning material stock box process Air, guaranteed the quality of product.
2, be provided with Pressure gauge, can understand timely the pressure of internal body, when appearance is unusual, can in time find, can avoid the appearance of waste product and the generation of accident, provide guarantee to safety in production.
Description of drawings
Fig. 1 is the structural representation of existing extruder;
Fig. 2 is the structural representation of the utility model extruder.
Among the figure: 1 body, 2 barrels, 3 moulds, 4 negative tubes, 5 material stock boxes, 51 first material stock boxes, 511 first imported valves, 512 first outlet valves, 52 second material stock boxes, 521 second imported valves, 522 second outlet valves, 6 vavuum pumps, 7 Pressure gauges.
The specific embodiment
As shown in Figure 2.Polyvinyl chloride extruder vacuum degree control device of the present utility model comprises body 1, and an end of body 1 is provided with barrel 2, and the other end is provided with mould 3, and the below of body 1 is connected with a vavuum pump 6 by negative tube 4; Negative tube 4 is provided with filter course with the junction of body 1, and negative tube 4 is provided with material stock box 5, and material stock box 5 is provided with openable seal cover.Described material stock box is set side by side with two, is respectively the first material stock box 51 and the second material stock box 52.The exit that the import department of the first material stock box 51 is provided with the first imported valve 511, the first material stock boxes 51 is provided with the first outlet valve 512; The exit that the import department of the second material stock box 52 is provided with the second imported valve 521, the second material stock boxes 52 is provided with the second outlet valve 522.
Described body 1 is provided with a Pressure gauge 7.
When the first imported valve 511 and 512 unlatchings of the first outlet valve, when the second imported valve 521 and the second outlet valve 522 were closed, the first material stock box 51 was connected with production line; Otherwise the second material stock box 52 is connected with production line; When all valves were all opened, the first material stock box 51 and the second material stock box 52 were all connected with production line.When clearing up the dust in the material stock box all valves of this material stock box are all closed, the work of another one material stock box had both guaranteed the continuity of producing, and can avoid again entering material at cleaning material stock box process Air, guaranteed the quality of product.The pressure of body 1 inside can be understood timely by Pressure gauge 7, when occurring in time to find when unusual, the appearance of waste product and the generation of accident can be avoided.
The above, principles more of the present utility model just explain through diagrams, this specification be not be the utility model to be confined to shown in described concrete structure and the scope of application, so every corresponding modify that might be utilized and equivalent all belong to the claim that the utility model is applied for.
Except the described technical characterictic of specification, all the other technical characterictics are those skilled in the art's known technology.
