Technical Field

[0001] The utility model belongs to the technical field of injection devices, in particular to a polysiloxane injection device. Background Art

[0002] Polysiloxane, also known as silicone oil, usually refers to linear polysiloxane products that remain liquid at room temperature. It is generally divided into two categories: methyl silicone oil and modified silicone oil. The most commonly used silicone oil is methyl silicone oil, also known as ordinary silicone oil. Its organic groups are all methyl. In the preparation process of certain polymer materials and new composite materials, polysiloxane is an indispensable material. During the preparation process, an injection device is required to inject polysiloxane into the raw materials of the polymer material for mixing.

[0003] Although there are many different injection devices available, some problems still exist. For example, current injection devices often require the addition of polysiloxane at regular intervals and in fixed quantities during injection. After one injection, the existing injection device needs to be removed and polysiloxane added again before injection can be continued. This makes continuous operation impossible and the operation is cumbersome, seriously affecting work efficiency. Utility Model Content

[0028] The injection mechanism 4 includes a servo motor 41, a linkage disk 42, a clamping disk 43, an abutment plate 44, a push rod 45 and a storage barrel 46. The servo motor 41 is fixed at the center of the top plate 1, and the linkage disk 42 is coaxially fixed on the output shaft of the servo motor 41, and is located between the top plate 1 and the bottom plate 3.
