[0002] MS sheet (plexiglass) is a plastic material with excellent transparency, strong impact resistance, and good processing properties. It is also commonly used as a transparent decorative material. It is easy to dye and process, and has an elegant appearance. It is widely used in the construction industry. Plexiglass products can generally be divided into cast sheet, extruded sheet, and molded material.

[0003] MS boards can be extruded and granular materials produced by suspension polymerization can be used to prepare organic glass plates, rods, tubes, sheets, etc. However, the profiles prepared in this way, especially the plates, will produce bubbles and impurities during the extrusion process, and the quality is uneven. However, the production cost of large-scale central vacuum equipment is high, and a single vacuum equipment cannot achieve consistent production quality. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a central vacuum pumping device for MS board extrusion production, which aims to improve the problems of bubbles and impurities generated during the acrylic extrusion process, ensure the quality and uniformity of the extruded material, and improve the problem of high production costs and the inability to achieve consistent production quality.

[0005] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a central vacuum pumping device for MS plate extrusion production, comprising a workbench, support plates fixedly connected to both sides of one end of the upper surface of the workbench, a support plate fixedly connected between the tops of the two support plates, a fixed plate fixedly connected to the middle of the support plate, an air intake pipe fixedly connected to the middle of the fixed plate, the air intake pipe runs through the middle of the fixed plate, a vacuum pumping mechanism fixedly connected between the two support plates, a sedimentation tank fixing plate fixedly connected to the middle of the workbench, a sedimentation tank fixedly connected to the tops of the two sedimentation tank fixing plates, a first electric ball valve fixedly connected to the upper air inlet of the sedimentation tank, an air intake on one side of the sedimentation tank fixedly connected to one end of the first vacuum tube, and a second vacuum tube fixedly connected to the upper part of the first electric ball valve.

[0006] Furthermore, the vacuum pumping mechanism includes a first vacuum pump and a second vacuum pump, the air intakes of the first vacuum pump and the second vacuum pump are fixedly connected to a first vacuum tube, the middle of the first vacuum tube is fixedly connected to a second electric ball valve, one end of the first vacuum tube is fixedly connected to a sedimentation tank, and the sides of the first vacuum pump and the second vacuum pump are fixedly connected to one side of the support plate.

[0007] Furthermore, an electric vacuum gauge is provided at one end of the upper portion of the sedimentation tank.

[0008] Furthermore, second vacuum tube fixing plates are fixedly connected to the lower surfaces of both ends of the second vacuum tube.

[0009] Furthermore, a third electric ball valve is fixedly connected to the lower air outlet of the sedimentation tank.

[0010] Furthermore, an air intake diversion pipe is fixedly connected to one side of the air intake pipe, and one end of the air intake diversion pipe is fixedly connected to one end of the second vacuum tube.

[0011] Furthermore, a controller is fixedly connected to the middle portion of one side of the support plate.

[0012] Furthermore, the controller is electrically connected to the first electric ball valve, the second electric ball valve and the third electric ball valve.

[0013] The utility model has the following beneficial effects:

[0014] 1. In the utility model, the two vacuum pumps of the vacuum mechanism can eliminate bubbles and impurities generated during the extrusion process, and the adsorbed water vapor and impurities can be precipitated through the sedimentation tank, so that the vacuum pump can operate safely and stably, thereby improving the operating efficiency of the equipment.

[0015] 2. In the utility model, the electric vacuum gauge, the first electric ball valve, the second electric ball valve and the third electric ball valve are electrically connected through the controller.

When the electric vacuum gauge detects that the vacuum value in the sedimentation tank deviates from the preset value, the second electric ball valve will automatically open and the vacuum pump will start running, ensuring the stable operation of the vacuum device of the equipment connected to the intake pipe and ensuring consistent production quality.
