Description

Technical Field

[0001] The utility model relates to the technical field of discharging mechanisms, in particular to a discharging mechanism of a raw material mixer. Background Art

[0002] The matrix of thermally conductive structural adhesive is usually epoxy resin adhesive, polyurethane adhesive and acrylate adhesive. In order to obtain thermal conductive properties, it is usually necessary to add thermally conductive powder with a volume fraction of more than 20% of the total amount of colloid to the adhesive matrix to form a thermal conductive channel. A mixer is required in the production of thermally conductive structural adhesive. The mixer is used to stir the raw materials of the thermally conductive structural adhesive. After the raw materials of the thermally conductive structural adhesive are stirred, they need to be discharged from the discharge structure.

[0003] The existing discharging structure usually pumps out the thermal conductive structural adhesive inside the mixer through a material pump connected to a pipe. When the thermal conductive structural adhesive is discharged through the pipe, there is air inside the pipe, which makes it difficult for the thermal conductive structural adhesive to completely fill the pipe at the beginning. At the same time, when the last part of the thermal conductive structural adhesive is pumped out, the outside air will also enter the pipe synchronously with the thermal conductive structural adhesive, which makes it difficult for the last part of the thermal conductive structural adhesive to completely fill the pipe, and it is not easy to evenly discharge the thermal conductive structural adhesive, which easily affects the packaging quality of the thermal conductive structural adhesive at the beginning and end.

[0004] The purpose of the utility model is to provide a discharging mechanism of a raw material mixer to solve the problems raised in the above background technology.

After the thermal conductive structural adhesive is accumulated in the discharge pipe, the air inside it is discharged through the exhaust frame, and the filter paper allows the air to pass through and blocks the thermal conductive structural adhesive. Therefore, when the thermal conductive structural adhesive is pumped out, at the beginning and end of the discharge of the thermal conductive structural adhesive, the thermal conductive structural adhesive is temporarily stored in the discharge pipe through the baffle, and the air inside the discharge pipe is discharged, so that the thermal conductive structural adhesive is easy to fill the pipe completely, and then the thermal conductive structural adhesive is discharged evenly, so as to prevent air from entering the discharge pipe and affecting the packaging quality of the thermal conductive structural adhesive at the beginning and end.

[0015] 2. Pull the limit rod to separate it from the limit hole and disassemble the fixing frame to facilitate the replacement of the filter paper.

After the thermal conductive structural adhesive is discharged, tighten the No. 2 bolt to separate it from the threaded ring, remove the block, and clean the inside of the discharge pipe from the cleaning pipe, so that the thermal conductive structural adhesive remaining inside the discharge pipe is easy to clean.
