[0019] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0020] Please refer to Figure 1-4 , the technical solution adopted by the utility model is:

[0021] A mixing device for coating production with fast discharging comprises a mixing tank, wherein a rotating rod with two ends passing through is rotatably connected to the top of the inner cavity of the mixing tank, a plurality of L-shaped stirring rods are fixedly connected to the outer wall of the rotating rod at equal angles, and the L-shaped stirring rods are bent upward, a pressing plate is slidably connected between the side walls of the inner cavity of the mixing tank, and the pressing plate abuts against the outer wall of the rotating rod, the L-shaped stirring rod passes through the inner cavity of the pressing plate and is slidably connected to the pressing plate, a pressing block is slidably connected between the side walls of the inner cavity of the rotating rod, and the pressing block and the pressing plate are horizontally arranged, two connecting blocks are connected between the pressing block and the pressing plate, the rotating rod is provided with a through groove that cooperates with the connecting block along the length direction, a mounting frame is fixedly connected to the top of the mixing tank, an electric cylinder is installed on the top of the mounting frame, the telescopic end of the electric cylinder is inserted into the inner cavity of the rotating rod and is rotatably connected to the pressing block, a driving motor is installed on the top of the mounting frame, the output end of the driving motor passes through the mounting frame and is installed with a driving gear, and the top of the rotating rod passes through the top of the mixing tank and is installed with a driven gear meshing with the driving gear.

[0022] From the above description, it can be seen that the beneficial effects of the utility model are:

[0023] When mixing the paint, the utility model can drive the rotating rod and the L-shaped stirring rod to rotate through the driving motor so as to stir and mix the raw materials of the paint. When the mixing is completed and the materials are discharged, the electric cylinder pushes the pressing block and the pressing plate to slide downward along the rotating rod and the L-shaped stirring rod, thereby squeezing the paint in the mixing tank and pushing the paint downward, thereby increasing the discharge speed of the paint.

[0024] Furthermore, a discharge pipe is connected to the bottom of the mixing tank, and the cross-section of the bottom of the mixing tank is a conical structure. The outer wall of the rotating rod is provided with spiral blades, and the spiral blades are located inside the discharge pipe.

[0025] From the above description, it can be seen that after the paint is mixed, the rotating rod drives the spiral blade to rotate, thereby conveying the paint, avoiding blockage inside the discharge pipe, and further increasing the discharge speed.

[0026] Furthermore, the driving motor is a forward and reverse rotating motor.

[0027] From the above description, it can be seen that when the motor rotates forward, it can drive the rotating rod and the spiral blade to rotate forward, wherein the rotating rod can stir and mix the raw materials, and the forward rotation of the spiral blade can transport the raw materials flowing into the discharge pipe upward to avoid the accumulation of raw materials in the discharge pipe. When the motor rotates reversely, it can stir and transport the mixed coating through the spiral blade.

[0028] Furthermore, the bottom cover of the discharge pipe is provided with an end cover, and a spacing is provided between the bottom of the rotating rod and the top of the end cover, the bottom of the pressing block is connected with an extrusion rod, and the extrusion rod is connected to the top of the end cover.

[0029] From the above description, it can be seen that under the push of the electric cylinder, the pressing block descends along the rotating rod, thereby pushing the end cover down and opening the end cover through the squeezing rod, thereby realizing the automatic opening of the end cover.

[0030] Furthermore, a rubber block that cooperates with the inner wall of the discharge pipe is arranged on the top of the end cover, and the cross-sectional shape of the rubber block is conical.

[0031] From the above description, it can be known that the deformation ability of the rubber block can more closely abut against the inner wall of the discharge pipe, thereby ensuring the sealing of the discharge pipe, and setting the rubber block to a cone can play a good role in guiding the flow.

[0032] Furthermore, a feed pipe is connected to the side wall of the mixing tank, and the connection between the feed pipe and the mixing tank is lower than the top of the L-shaped stirring rod.

[0033] From the above description, it can be seen that when adding materials, raw materials can be added to the mixing tank through the feeding pipe, and when adding materials through the feeding pipe, the pressing plate can be along the top of the L-shaped stirring rod so that the added raw materials will not run above the pressing plate.

[0034] Please refer to Figures 1 to 4 As shown, the first embodiment of the utility model is:

[0035] Please refer to Figure 1 , Figure 3 and Figure 4 A mixing device for coating production with fast discharging comprises a mixing tank 1, wherein a rotating rod 2 with two ends passing through is rotatably connected to the top of the inner cavity of the mixing tank 1, a plurality of L-shaped stirring rods 3 are fixedly connected to the outer wall of the rotating rod 2 at equal angles, and the L-shaped stirring rods 3 are bent upward, a pressing plate 4 is slidably connected between the side walls of the inner cavity of the mixing tank 1, and the pressing plate 4 abuts against the outer wall of the rotating rod 2, the L-shaped stirring rod 3 passes through the inner cavity of the pressing plate 4 and is slidably connected to the pressing plate 4, a pressing block 5 is slidably connected between the side walls of the inner cavity of the rotating rod 2, and the pressing block 5 and the pressing plate 4 are horizontally arranged, and the pressing block 5 and the pressing plate 4 are arranged horizontally. There are two connecting blocks 6 connected in between, and the rotating rod 2 is provided with a through groove 7 which cooperates with the connecting block 6 along the length direction. A mounting frame 8 is fixedly connected to the top of the mixing tank 1, and an electric cylinder 9 is installed on the top of the mounting frame 8. The telescopic end of the electric cylinder 9 is inserted into the inner cavity of the rotating rod 2 and is rotatably connected to the pressing block 5 through a rotating bearing. A driving motor 10 is installed on the top of the mounting frame 8. The output end of the driving motor 10 passes through the mounting frame 8 and is installed with a driving gear 11. The top of the rotating rod 2 passes through the top of the mixing tank 1 and is installed with a driven gear 12 which is meshed with the driving gear 11.

[0036] Please refer to Figure 1The bottom of the mixing tank 1 is connected to a discharge pipe 13 , and the cross-section of the bottom of the mixing tank 1 is a conical structure. The outer wall of the rotating rod 2 is provided with a spiral blade 14 , and the spiral blade 14 is located inside the discharge pipe 13 .

[0037] Please refer to Figure 1 , the driving motor 10 is a forward and reverse motor.

[0038] Please refer to Figure 2 The bottom cover of the discharge pipe 13 is provided with an end cover 15, and a distance is provided between the bottom of the rotating rod 2 and the top of the end cover 15. The bottom of the pressing block 5 is connected with an extrusion rod 16, and the extrusion rod 16 is connected to the top of the end cover 15.

[0039] Please refer to Figure 2 A rubber block 17 that cooperates with the inner wall of the discharge pipe 13 is provided on the top of the end cover 15, and the cross-sectional shape of the rubber block 17 is conical.

[0040] Please refer to Figure 1 The side wall of the mixing tank 1 is connected with a feed pipe 18 , and the connection between the feed pipe 18 and the mixing tank 1 is lower than the top of the L-shaped stirring rod 3 .

[0041] The working process of the above mixing device is as follows:

[0042] When mixing the coating, the electric cylinder 9 first drives the pressing block 5 and the pressing plate 4 to slide upward to the top of the L-shaped stirring rod 4, and then the coating raw materials are added into the mixing tank 1 through the feeding pipe 18;

[0043] Then, the driving motor 10 is started in the positive direction. The driving motor 10 drives the driven gear 12 and the rotating rod 2 to rotate through the driving gear 11, thereby driving the stirring rod to stir and mix the raw materials inside the mixing tank 1. During the coating mixing process, part of the coating flows into the rotating rod 2 through the through groove 7 and flows out from the opening at the bottom of the rotating rod 2. At this time, the rotating rod 2 drives the spiral blade 14 to rotate in the positive direction, thereby transporting the raw materials in the discharge pipe 13 upward, realizing the up and down flow of the coating, and improving the mixing effect.

[0044] After the paint is mixed, the electric cylinder 9 is started, and the electric cylinder 9 pushes the pressing block 5 and the extrusion rod 16 down, thereby driving the pressing plate 4 to slide downward along the through groove 7, and then the paint inside the rotating rod 2 and the mixing tank 1 is squeezed and pushed downward by the pressing plate 4 and the pressing block 5. At the same time, the extrusion rod 16 descends to push the end cover 15 to slide downward and open, so that the paint flows out quickly under the action of pressure, and the paint inside the rotating rod 2 can also flow out through the opening at the bottom of the rotating rod 2;

[0045] At the same time, when the paint is discharged, the drive motor 10 is started in reverse, and the drive motor 10 drives the stirring rod and the spiral blade 14 to rotate in the opposite direction, so that the paint is quickly pushed out through the spiral blade 14 to prevent the paint from clogging the discharge pipe 13.

[0046] After the discharge is completed, the electric cylinder 9 is retracted to allow the pressing plate 4 to slide back to the top position of the stirring rod, and then the raw materials are added again through the feeding pipe 18.

[0047] To sum up, the utility model provides a mixing device for paint production with fast discharging. When mixing the paint, the driving motor can drive the rotating rod and the L-shaped stirring rod to rotate so as to stir and mix the raw materials of the paint. When discharging after mixing, the electric cylinder pushes the pressing block and the pressing plate to slide downward along the rotating rod and the L-shaped stirring rod, thereby squeezing the paint in the mixing tank and pushing the paint downward, thereby increasing the discharging speed of the paint.
