The above-mentioned solution solves the problem that with the diversification and development of enterprise products, more and more types of coupling agents are involved, and the space on the production site is limited, resulting in that some types of coupling agents that need to be protected cannot be protected by nitrogen. During use, the barrel cover must be opened and closed frequently to prevent reaction, which makes the operation cumbersome and affects work efficiency. At the same time, it is also impossible to better guarantee the quality of the coupling agent. It can be understood that the above-mentioned solution can be used to enable the coupling agent to be taken out without frequently opening and closing the barrel cover during use, thereby blocking the contact between air and the coupling agent, and protecting the coupling agent.

The pipeline 103 adds nitrogen into the raw material barrel 101, and adjusts the nitrogen pressure in the raw material barrel 101 through the control component to make the pressure slightly higher than the atmospheric pressure, so as to use the pressure difference as the power of discharging, so that the coupling agent is discharged outward through the discharge pipeline 104, thereby avoiding the need to frequently open and close the barrel cover during use to prevent the coupling agent from reacting with air, and protecting the coupling agent. The auxiliary component is arranged on the threaded sealing cover 102. The arrangement of the auxiliary component can enhance the air tightness between the air inlet pipeline 103 and the threaded sealing cover 102 and the air tightness between the discharge pipeline 104 and the The airtightness between the threaded sealing cover 102 is ensured, thereby protecting the coupling agent in the raw material barrel 101.
