2results about How to "Good anti-drip effect" patented technology

The utility model discloses a kind of anti-dripping pesticide filling machines, it is related to pesticide filling technical field, improve the problem that pesticide is prone to drip to outside in filling process, anti-dripping effect is poor, including bottom box, the top of the bottom box is fixedly installed with pesticide storage tank by support plate, the top of the right side of pesticide storage tank is fixedly installed with anti-dripping plate, the top of the anti-dripping plate is provided with filling mechanism, the utility model is stored frame by setting, it is convenient to store the container needing filling, by setting filling mechanism, pesticide filling can be carried out to container, by setting servo motor, threaded rod, threaded sleeve, bearing plate and push plate, stored frame and the container placed can be driven to move upwards, make medicine pipe stretch into container, and make the bottom of anti-dripping plate and the top of container contact, improve anti-dripping effect, this mode is good in filling anti-dripping effect, pesticide is not prone to spatter to outside, use safety.

The application relates to a drip-proof gravity back-suction structure of a high-viscosity vinegar filling valve and relates to the technical field of filling valves, which comprises a valve body, the inner side of the valve body is provided with a valve core assembly, and the valve core assembly comprises a valve core main body which is slidably connected to the inner side of the valve body. The application is characterized in that the valve core assembly is arranged on the inner side of the valve body, the back-suction channel in the inner side of the valve core main body is matched with the communicating pipe, the collecting box and the negative pressure adsorption assembly on the outer side of the valve body, after filling is completed, the second cylinder in the negative pressure adsorption assembly drives the piston plate to move upwards, a negative pressure is formed in the collecting box, the high-viscosity vinegar liquid remaining in the valve port is timely sucked into the collecting box through the back-suction channel, the problem that the residual vinegar liquid is difficult to clean and dripping frequently in the conventional technology is effectively solved, the structure can be adapted to filling of vinegar liquids with different viscosities, the application range of the conventional technology is broken through, meanwhile, the taper matching structure of the valve core main body and the valve body is combined with the first sealing ring, the rubber sleeve and the second sealing ring, the sealing performance is enhanced, and the drip-proof effect is improved.
