Description

Technical Field

[0001] The utility model relates to the technical field of paint filling, in particular to a paint canning device. Background Art

[0002] Water-based paints include water-soluble paints, water-dilutable paints, and water-dispersible paints (latex paints). Water-soluble paints use water-soluble resins as film-forming materials, represented by polyvinyl alcohol and its various modified products. In addition, there are water-soluble alkyd resins, water-soluble epoxy resins, and inorganic polymer water-based resins. In the production process of water-based paints, the paints need to be filled and sealed before transportation. Workers often use filling machines to assist in the filling of water-based paints.

[0003] When using existing water-based paint filling machines, the water-based paint is generally filled into containers by manually controlling valves. The filling accuracy of the water-based paint is poorly controlled, and it is very easy for the filling volume to be higher or lower than the specified value, affecting the filling effect of the water-based paint. Utility Model Content

[0004] The disclosed embodiments relate to a paint canning device, which solves the problem that, when in use, existing water-based paint filling machines generally use a manually controlled valve to fill the water-based paint into a container, which has poor control over the filling accuracy of the water-based paint and easily leads to the filling volume being higher or lower than a specified value.

[0005] In a first aspect of the present disclosure, a paint canning device is provided, which specifically includes: a filling body; a servo motor is fixedly installed on the outside of the filling body, and a crankshaft is installed in the bottom of the filling body; a pumping piston is installed in the top of the filling body, and a transmission rod is connected to the bottom of the pumping piston, and the crankshaft is connected to the transmission rod; a top cover is fixedly connected to the top of the filling body, a one-way valve A and a one-way valve B are installed on the top of the top cover, a liquid inlet pipe is installed at one end of the one-way valve A, and the liquid inlet pipe is connected to the liquid supply pipeline; a liquid discharge pipe is installed at one end of the one-way valve B, the liquid discharge pipe is fixedly connected to the filling body, a filling nozzle is installed at the front end of the liquid discharge pipe, and a bolt is connected to the outside of the filling nozzle.

[0006] In at least some embodiments, a pumping cavity is provided in the top of the filling body, a pumping piston is slidably connected to the pumping cavity provided in the filling body, a three-way pipe is provided on the top of the top cover, and the bottom of the three-way pipe is connected to the pumping cavity.

[0007] In at least some embodiments, the crankshaft is rotatably connected to the filling body, and the drive shaft of the servo motor is connected to one end of the crankshaft.

[0008] In at least some embodiments, the bottom end of the transmission rod is rotatably connected to the crankshaft, and the top end of the transmission rod is rotatably connected to the pumping piston.

[0009] In at least some embodiments, one end of the three-way pipe is connected to the liquid inlet pipe through a one-way valve A, and the other end of the three-way pipe is connected to the liquid discharge pipe through a one-way valve B. The servo motor drives the crankshaft to rotate, and the crankshaft drives the pumping piston to move back and forth up and down in the pumping chamber through the transmission rod. When the pumping piston moves downward, the water-based paint is sucked into the pumping chamber through the one-way valve A. When the pumping piston moves upward, the water-based paint in the pumping chamber is discharged through the one-way valve A under the influence of pressure, and the water-based paint is intermittently filled into the container.

[0010] In at least some embodiments, the end of the discharge pipe is slidably connected to the filling nozzle, and two sealing rings are installed on the outer side of the end of the discharge pipe, and the sealing rings are in sliding contact with the inner wall of the filling nozzle.

[0011] In at least some embodiments, a screw hole is provided at the bottom of the filling nozzle, and a bolt is threadedly connected to the screw hole provided at the filling nozzle, and the bottom of the bolt is in contact with the outer wall of the discharge pipe. The filling nozzle can be adjusted to move forward and backward according to the different water-based paint storage containers, and the distance between the liquid outlet end of the filling nozzle and the filling body can be changed, so that the liquid outlet end of the filling nozzle is directly above the container mouth, thereby ensuring the filling effect of the water-based paint, better adapting to the filling needs of different containers, and having strong versatility.

[0012] The utility model provides a coating canning device, which has the following beneficial effects:

[0013] When the utility model is in use, the servo motor drives the crankshaft to rotate, and the crankshaft drives the pumping piston to move back and forth up and down in the pumping chamber through the transmission rod. When the pumping piston moves downward, the water-based paint is sucked into the pumping chamber through the one-way valve A. When the pumping piston moves upward, the water-based paint in the pumping chamber is discharged through the one-way valve A under the influence of pressure, and the water-based paint is intermittently filled into the container. The volume of the pumping chamber is fixed to ensure the consistency of the single water-based paint delivery amount. The filling amount of the water-based paint can be automatically and accurately controlled by controlling the number of single start and stop operations of the servo motor.

[0014] In addition, the filling nozzle can be adjusted to move forward and backward according to the different water-based paint storage containers, and the distance between the liquid outlet end of the filling nozzle and the filling body can be changed to make the liquid outlet end of the filling nozzle directly above the container mouth, thereby ensuring the filling effect of water-based paint and better adapting to the filling needs of different containers. It has strong versatility. After the filling nozzle is moved and adjusted, the contact part between the filling nozzle and the discharge pipe is sealed by a sealing ring, and the connection part between the filling nozzle and the discharge pipe is fixed by bolts to ensure the stability of the filling nozzle state.
