Description
Technical Field
The utility model belongs to the technical field of the modified plastics extrusion and specifically relates to the field that extruder evacuation easily blockked up, concretely relates to plastics that can change on line vacuum piping installation for extrusion equipment.
Background
With the progress of society, the plastic industry develops vigorously, the use range of plastics is wider and wider, the requirements of parts on the performance and the function of the plastics are higher and higher, and the simple synthetic resin and the modified resin can not meet the changing requirements. The plastic extrusion modification is used as a means for improving the multifunctional and high-use performance of the plastic, the requirements are stricter and stricter, and due to the diversity of the plastic modification additive, the frequency of blockage of a vacuum pipeline is higher and higher. The extrusion vacuumizing is used as an important auxiliary function for plastic extrusion modification, and the capacity and efficiency of the vacuum vacuumizing determine the yield and the product stability of the modified plastic. Therefore, it is very important to design a vacuum pipeline that can be cleaned and replaced online.
SUMMERY OF THE UTILITY MODEL
The utility model provides a plastics that can change on line vacuum piping installation for extrusion equipment. The above technical problems of the prior art have been solved.
In order to solve the technical problem, the utility model discloses a realize through following technical scheme:
a vacuum pipeline device for plastic extrusion equipment capable of being replaced on line comprises a first three-way connector communicated with a vacuum port of an extruder and a second three-way connector communicated with a vacuum pump; the main pipe of the first three-way connector is connected and communicated with the vacuum port of the extruder; the main pipe of the second three-way connector is connected and communicated with the second three-way connector; the branch pipes of the first three-way connector and the branch pipes of the second three-way connector are connected and communicated with each other in pairs through two branch pipes respectively; and the openings of the two branch pipes of the first three-way connector and the second three-way connector are respectively provided with a pneumatic valve for controlling the pipeline to be opened or closed.
The two ends of the branch pipe are respectively connected with the branch pipes of the first three-way connector and the second three-way connector in an airtight mode in a sleeving mode. The branch pipe and the branch pipe are fixed through a quick joint.

The three-way connector is a same-diameter three-way connector or a different-diameter three-way connector.
Compared with the prior art, the utility model, following obvious advantage has:
1. the double-pipeline design ensures the stability and the error proofing of the vacuum pumping equipment;
2. the independent operation of the branch pipes is realized, so that the blocked pipes are cleaned without shutdown or unqualified products, and the production efficiency and the product stability are improved;
3. the branch pipes are connected by quick connectors, and are convenient to disassemble.
Drawings
FIG. 1 is a schematic view of a vacuum line apparatus;
in the figure, 1, a first three-way connector; 2. a second three-way connector; 3. pipe distribution; 4. a pneumatic valve; 5. a quick coupling.
Detailed Description
The structural features of the present invention will be further explained with reference to the accompanying drawings and specific embodiments.
The vacuum pipeline device for the plastic extrusion equipment, which can be replaced on line as shown in fig. 1, comprises a first three-way connector communicated with a vacuum port of an extruder and a second three-way connector communicated with a vacuum pump; the main pipe of the first three-way connector is connected and communicated with the vacuum port of the extruder; the main pipe of the second three-way connector is connected and communicated with the second three-way connector; the branch pipes of the first three-way connector and the branch pipes of the second three-way connector are connected and communicated with each other in pairs through two branch pipes respectively; and the openings of the two branch pipes of the first three-way connector and the second three-way connector are respectively provided with a pneumatic valve for controlling the pipeline to be opened or closed.
The two ends of the branch pipe are respectively connected with the branch pipes of the first three-way connector and the second three-way connector in an airtight mode in a sleeving mode. The embodiment is firmer and convenient to disassemble, and the branch pipe are fixed through a quick connector after being sleeved.
The three-way connector is a Y-shaped three-way connector or a T-shaped three-way connector.
The three-way connector is a same-diameter three-way connector or a different-diameter three-way connector.
The utility model discloses have two relatively independent branch pipe two parts and constitute. When the pipeline plugging device is used, after one branch pipe normally works for a period of time and a pipeline is plugged, the pneumatic valve of the other pipeline is opened, the pipeline is kept smooth, the pneumatic valve of the plugged pipeline is closed, and the branch pipe is detached, cleaned and then installed back to the original position. The process does not need to stop the vacuumizing device and stop the machine, does not influence the quality of the produced products, and greatly improves the stability and the production efficiency of the produced products.
