Detailed Embodiments

[0020] The following will combine with the attached Figures 1 to 4 to make a detailed description of the present utility model.

[0021] A liquid silicone lifting defoaming machine of the present utility model includes a housing 1. A positioning ring 11 is arranged inside the housing 1. A stirring motor 12 is arranged at the top of the housing 1. The extending end of the stirring motor 12 extends into the housing 1 and is provided with a stirring rod 13. A vacuum device 2 is arranged outside the housing 1. The vacuum device 2 is provided with an air pipe 21. An air hole connected to the air pipe 21 is arranged on the housing 1, and the air hole is located within the positioning ring 11. A lifting device 3 is arranged at the bottom of the housing 1. The lifting device 3 is provided with a support rod 31 extending upward, and a support plate 32 is arranged at the end of the support rod 31. It includes a material bucket 4. The material bucket 4 is cylindrical and can accommodate liquid silicone within 2000L. The outer diameter of the port of the material bucket 4 is smaller than the inner diameter of the positioning ring 11. The port of the material bucket 4 can be connected to the positioning ring 11 to isolate the air inside the material bucket 4 from the outside. A limiting plate 41 corresponding to the internal geometric structure of the housing 1 is arranged at the outer end of the material bucket 4. This structure enables the material bucket 4 to only perform lifting activities within the housing and cannot rotate. A guiding groove 14 and a clamping plate 5 movably connected to the guiding groove 14 are also arranged inside the housing 1. A positioning port 51 for positioning the material bucket 4 is arranged in the middle of the clamping plate 5. During use, the material bucket 4 loaded with liquid silicone is transported to the clamping plate 5. Through the guiding groove 14 and the clamping plate 5, the material bucket 4 is pushed into the housing 1. After the clamping plate 5 abuts against the inner wall of the housing 1, the lifting device 3 drives the support rod 31 to rise, and the support plate 32 supports the material bucket 4 and continuously moves upward until the port of the material bucket 4 is docked with the positioning ring 11. Then the vacuum device 2 and the stirring motor 12 are started. While the stirring rod 13 stirs the materials in the material bucket 4, the vacuum device 2 extracts the air in the material bucket 4. This defoaming machine has high airtightness and fast defoaming speed. Through the large-volume material bucket 4, a large amount of liquid silicone raw materials can be stirred and degassed by vacuum at one time. The transportation process of the material bucket 4 does not require manual handling, with high efficiency and convenient operation.

[0022] The clamping plate 5 is provided with a first connecting piece 52 and a second connecting piece 53. The first connecting piece 52 is connected to the guiding groove 14. After the material bucket 4 is docked with the first connecting piece 52, connecting the second connecting piece 53 to the first connecting piece 52 can connect the material bucket 4 to the positioning port 51. Positioning the material bucket 4 can facilitate the lifting device 3 to accurately lift the material bucket 4 to a specified height.

[0023] The first connecting member 52 is provided with a connecting hole 54, and the second connecting member 53 is provided with a screw rod 55 that can be positioned with the connecting hole 54. The material barrel 4 is transported to a specific position by a transportation device such as a transport vehicle or a crane, so that the outside of the material barrel 4 abuts against the first connecting member 52. Then, the staff inserts the screw rod 55 into the connecting hole 54 and tightens it to splice and fix the second connecting member 53 to the first connecting member 52. By pushing the second connecting member 53, the material barrel 4 can be pushed into the housing 1.

[0024] A pressure valve 15 is provided at the top of the housing 1. The pressure valve 15 can be used to balance the pressure in the material barrel 4. After the liquid silicone defoaming is completed, the material barrel 4 can descend smoothly.

[0025] A sealing ring is provided at the port of the material barrel 4. The sealing ring can improve the airtightness after the material barrel 4 is connected to the positioning ring 11 and prevent air leakage from affecting the defoaming of the vacuum device 2.

[0026] A through port 16 for the material barrel 4 to pass through is provided on one side of the housing 1. A platform portion 6 is provided outside the housing 1 near the through port 16, and a multi-stage step 61 is provided on one side of the platform portion 6. In the solution of the present utility model, the housing 1 includes three parts: an upper layer, a middle layer, and a lower layer. The lifting device 3 is arranged in the lower layer portion of the housing 1, and the through port 16 and the guiding groove 14 are arranged in the middle layer portion of the housing 1. The lifting device 3 will lift the material barrel 4 placed in the middle layer portion to the upper layer portion for vacuum defoaming. The platform portion 6 has a certain height, and the staff can step onto the platform portion 6 through the multi-stage step 61, which is convenient for operating the equipment.

[0027] The platform portion 6 is provided with a table board 62, and a support column 63 is provided below the table board 62. The position of the table board 62 is close to the top height of the lower layer portion of the housing 1. The support column 63 supports and stabilizes the table board 62, which is convenient for the staff to stand on the table board 62 and has high safety.

[0028] The platform portion 6 is provided with a detachable splicing rod 64. The connecting rod can connect an additional step portion, which is convenient for tools such as transport vehicles to move on the platform portion 6.

[0029] A fixing seat 17 is provided at the top of the housing 1, and the stirring motor 12 is fixedly connected to the fixing seat 17. The fixing seat 17 is detachably connected to the housing 1. By detaching the fixing seat 17, the stirring motor 12 and the stirring rod 13 can be removed, which is convenient for maintenance and replacement of stirring rods 13 with different shapes.

[0030] The above content is only the preferred embodiment of the present utility model. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present utility model.
