Production line for preparing welding seam glue

Abstract

The invention discloses a production line for preparing a welding seam glue, which comprises a kneading machine, a kneading screw discharging device, a mixing tank, a mixing screw discharging device, a filter and a barreling device, wherein, the kneading machine comprises a cylinder body and a cylinder cover; a discharge port is formed in the bottom of the cylinder body; a feed port of the kneading screw discharging device is connected with the discharge port of the cylinder body; a discharge port of the kneading screw discharging device is communicated with a material adding port of the mixing tank; a vacuum orifice, the material adding port and a liquid phase port are formed in the top of the mixing tank; a discharge port is formed in the bottom of the mixing tank; the vacuum orifice is connected with a vacuum device; the discharge port of the mixing tank is connected with the mixing screw discharging device; the liquid phase port is connected with a liquid phase adding pipeline; the mixing screw discharging device is connected with the filter; the filter is connected with the barreling device. According to the production line provided by the invention, the kneading machine and the mixing tank adopt the screw discharging device for discharging, the discharge is more smooth, the pressure is more strong, the cylinder body of the kneading machine fall does not need to topple, the structure is simpler and the maintenance is more convenient.

Description

technical field [0001] The invention relates to a production line for preparing welding seam glue, which is used for automobiles. Background technique [0002] The preparation method of weld glue has become mature. The powdery material and liquid material are added to the kneader for stirring. Because of its high viscosity, a kneader is needed to mix evenly. After stirring, the kneader cylinder is dumped. Send the stirred material into the mixing tank, add the liquid phase material into the mixing tank and stir, mix again and adjust the solid-liquid ratio and viscosity, and finally use high-pressure gas to press the material in the mixing tank into the discharge pipe In the process, a filter is set on the discharge pipe, and the material passes through the filter to filter out impurities with large particle size, and then it is sent to the barreling device for barreling. [0003] However, this welding seam adhesive production line has the following technical defects: 1. The...

Problems solved by technology

[0003] However, this welding seam adhesive production line has the following technical defects: 1. The mixing kettle uses high-pressure gas as the power for discharging, and when the high-pressure gas is introduced, the kettle body becomes a high-pressure equipment, which requires the performance of the kettle body to be high-pressure. Explosion-proof performance, the cost of the kettle body increases, and there are also potential safety hazards. Even if high-pressure gas is introduced, the discharge rate is not high, the discharge pressure is insufficient, and the fluidity when passing through the filter is poor and easy to block.

2. The kneader adopts the structure of turning the cylinder and dumping. This structure is easy to be damaged, the maintenance cost is high, and the cylinder needs to be turned over, which consumes a lot of energy, and the viscosity of the material is high, and the dumping is not thorough enough; 3. The current filtration When the filter is in use, the material enters the outer cylinder from the inside of the inner filter cartridge, and the particles with relatively large particle size will be filtered and attached to the inner wall of the inner filter cartridge. Not easy to clean on the inner wall of the inner filter cartridge

When cleaning the inner filter cartridge, it is necessary to lift the inner filter cartridge from above, and then clean the inner filter cartridge. Due to the presence of weld glue, it takes a lot of force to take out the inner filter cartridge, which is difficult to remove
