DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0026] See also Figures 1 to 6 The present invention provides a technical solution: a device for producing carbon dioxide by vacuum foaming of XPS extruded board, comprising a base 1, a fixed base 2 being fixed on the base 1, a power mechanism 3 being fixedly installed on the fixed base 2, the power mechanism 3 being a driving motor, the driving motor providing power for the rotation of a screw rod 38, a transmission box 4 being fixedly installed on the side of the power mechanism 3, a support base 5 being installed on the side of the transmission box 4, the support base 5 being fixed on the fixed base 2, a connecting box 6 being fixed on the side of the support base 5, a supporting box 7 being fixedly installed on one side of the connecting box 6, a supporting frame 8 being fixed on the bottom of the supporting box 7, one end of the supporting frame 8 being fixed on the base 1, a feeding box 10 being fixed on the side of the supporting box 7, a feeding assembly 9 being fixedly installed on the feeding box 10, the supporting frame 8 being fixed inside the supporting box 7, and the supporting frame 8 providing supporting force for the supporting box 7.

[0028] In this embodiment, a stirring motor 17 and a feeding pipe 16 are fixedly installed on the top of the barrel body 15, and an extrusion auger 24 is installed on the stirring motor 17. The extrusion auger 24 is rotatably installed inside the barrel body 15. A barrel 20 is fixed on the side of the barrel body 15, and a material bucket 22 is fixed on the top of the barrel body 20. A connecting seat 21 is fixed on the bottom of the barrel body 20, and the connecting seat 21 is fixed on the support box 7. A conveying motor 23 is fixedly installed at one end of the barrel body 20. The conveying motor 23 A pushing auger 25 is installed on it, and the pushing auger 25 is rotatably installed inside the cylinder 20. A slot 27 is provided on the top of the protective cover 11, and an air inlet pipe 28 is movably installed inside the slot 27. A fixed pipe 33 is movably installed on the air inlet pipe 28, and the fixed pipe 33 is rotatably installed on the dissolving material seat 32. The extrusion auger 24 pushes the material to move downward and performs preliminary stirring and mixing between the raw materials. Under the push of the extrusion auger 24, the material actively enters the interior of the feed box 10 for processing.

[0029] In this embodiment, a marking line 34 is fixedly installed on the fixed tube 33, an indicator line 35 is fixed on the air inlet pipe 28, and the indicator line 35 cooperates with the marking line 34. An adding tube 30 is fixedly installed on the side of the dissolving seat 32, a mounting hole is opened on the dissolving seat 32, and an internal thread is opened on the inner wall of the mounting hole.

The spiral rod 38 includes a spiral rod 1 and a spiral rod 2, and the spiral rod 1 and the spiral rod 2 are meshed. After the indicator lines 35 and the marking lines 34 at different positions are distributed oppositely, the position of the exhaust holes 40 of different diameters and the openings 39 can be quickly understood.

[0030] When the device is in use, the required principle is added to the inside of the barrel 15 and the material barrel 22. After different materials are added separately in the early stage, the conveying motor 23 is started to drive the pushing auger 25 to rotate, and the pushing auger 25 pushes the raw materials in the material barrel 22 into the inside of the barrel 15. The inside of the barrel 15 continues to enter another principle. Under the push of the pushing auger 25, the two raw materials are preliminarily mixed. When the material in the material barrel 22 completely enters the inside of the barrel 15, the stirring motor 17 is started, and the stirring motor 17 drives the extrusion auger 24 to rotate. 24 pushes the raw materials in the barrel 15 to move downward, and the raw materials are mixed and stirred again while moving downward. The raw materials enter the feed seat 19 under the push of the extrusion auger 24, and the heating mechanism 26 in the feed seat 19 is opened in advance. The heating mechanism 26 heats the inner wall of the feed seat 19. As the material flows at the inner wall of the feed seat 19, the raw materials moving in the feed seat 19 are preliminarily melted, and the melted materials enter the interior of the feed box 10. The spiral rod 38 in the feed box 10 pushes the material into the interior of the melt seat 32, and the melt seat 3 2 The internal heating plate is heated and melted again. After the spiral rod 38 pushes the material into the position of the fixed tube 33, the foaming agent is introduced into the inside of the melt seat 32 through the adding tube 30. The foaming agent contacts the raw material. After the contact, the material cooperates with the fixed tube 33 to generate resistance. The material is squeezed under the resistance. The extrusion makes the material and the foaming agent mix. When the foaming agent and the raw material are mixed, they are connected to the air inlet pipe 28 through the external air pipe. The air inlet pipe 28 rotates on the fixed tube 33 before air intake. The rotation makes the indicator line 35 at different positions cooperate with the marking line 34 to match the exhaust hole of the used diameter. 40 cooperates with the opening 39 to inject carbon dioxide into the raw material. The direction of the opening 39 is the same as the direction of material movement, which can effectively prevent the raw material from entering the inside of the opening 39. After the raw material is heated and extruded, it is discharged from the inside of the discharge port 12. A vacuum exhaust hole is installed on the melt seat 32. The function of the vacuum exhaust hole is a common mature technology of existing extrusion equipment. Vacuum exhaust can be used directly on this device. When it is not in use later, the fixed tube 33 can be rotated, and the threaded tube 36 on the fixed tube 33 is removed from the melt seat 32. The fixed tube 33 is removed for cleaning.
