Description

Technical Field

[0001] The utility model relates to the technical field of sealant filling, in particular to an organosilicon sealant filling and packaging machine. Background Art

[0002] At present, sealant refers to a sealing material that deforms with the shape of the sealing surface, is not easy to flow, and has a certain degree of adhesion. Silicone sealant is a polymer material, mainly used for sealing applications in various industrial and construction fields. It is made of silane-based polymerization and has good flexibility, corrosion resistance, high temperature stability and electrical properties. Silicone sealant exhibits excellent performance in bonding, waterproofing, moisture-proofing, high temperature resistance and corrosion resistance. The sealant needs to be filled during the production process.

[0003] For example, an automatic filling and packaging machine for sealant with publication number CN211619921U includes a filling tank and a discharge pipe, the discharge pipe is connected to the middle part of the lower end of the filling tank, and the discharge pipe is connected to the inside of the filling tank, a solenoid valve is fixedly installed in the middle part of the discharge pipe, a first stirring rod is rotatably installed laterally inside the discharge pipe at the upper end of the solenoid valve, and a second stirring rod is rotatably installed laterally inside the discharge pipe at the lower end of the solenoid valve, the first stirring rod is transmission-connected to a first motor fixed to the surface of the discharge pipe at the upper end of the solenoid valve, and the second stirring rod is transmission-connected to the surface of the discharge pipe at the lower end of the solenoid valve, the first stirring rod and the second stirring rod are respectively fixed to the upper and lower ends of the solenoid valve in the discharge pipe, and both can be driven to rotate, so that the first stirring rod and the second stirring rod can be rotated at the same time when the solenoid valve is opened to start filling, thereby avoiding blockage of the upper and lower ends of the solenoid valve inside the discharge pipe and ensuring smooth filling.

[0004] Based on the above, it can be seen that the following technical problems exist in the prior art: Since silicone sealant has a certain viscosity, it may encounter certain resistance during the outflow process, and its flow effect is not very ideal. The existing device usually only relies on the effect of gravity to make the sealant flow out of the discharge pipe. When the total amount of sealant inside the filling tank decreases, the outflow speed of the sealant will also slow down, which may have a negative impact on the filling efficiency. In order to solve the problems existing in the prior art, the present application proposes a silicone sealant filling and packaging machine. Utility Model Content

[0030] A shell 5 and a cylinder 15 are fixed on the top of the filling tank 4. The cylinder 15 is located inside the shell 5.
