A weighing mixer is a production equipment used in industry to automatically and accurately formulate different powder or liquid main and auxiliary materials in a certain proportion. It is usually composed of a Weighing system, weighing module, weighing control instrument, PLC system, and upper computer. The weighing mixer includes a planetary mixer and a container. One side of the planetary mixer is equipped with a feeding device and a feeding box transmission device. One side of the feeding device is connected to an output bucket, and one side of the output bucket is equipped with a discharge port. The feeding box transmission device is equipped with a motor and a blocking plate, and the blocking plate is connected to the motor transmission. The blocking plate is connected to the discharge port in a flexible manner. The feeding device is equipped with a pump and a feeding port on one side. One output end of the pump is connected to the feeding port, and the other output end is connected to the output bucket. A leak proof spoon is installed on one side of the container. The output end of the motor is connected to a first gear set for rotation, and one side of the first gear set is meshed with a second gear set. The second gear set is connected to the shielding plate through a bearing. One side of the output bucket is provided with a support frame, which is connected to the first gear set for movement. One side of the feeding port is equipped with a cover. The inside of the leak proof spoon is equipped with a slope. Polish the side of the shielding plate near the discharge port. The mixer puts the material into the outlet through the feeding port, and then drives the pump to pump the internal material into the output bucket. Then, the motor is driven to rotate the first gear set, which in turn drives the second gear set to rotate, and the second gear set in turn drives the blocking plate to rotate. As the blocking plate is in contact with the outlet, it can periodically block the outlet by rotating the blocking plate. By adjusting the output power of the motor, the speed of the blocking plate can be adjusted, thereby achieving the adjustment of the feeding speed; After the material is output from the discharge port, it can flow into the leak proof spoon, and then flow into the container through the slope inside the leak proof spoon. Then, it can be stirred and mixed by a planetary mixer.

The weighing mixer is equipped with a hopper scale and a bottom plate set below the hopper scale. The bottom of the hopper scale is provided with support feet, and a weighing module is detachably connected between the bottom plate and the support feet. The top and bottom surfaces of the weighing module are respectively connected to the support feet and the bottom plate by bolts. The bottom surface of the bottom plate is provided with a support frame, and the bottom end of the hopper scale is detachably connected to a discharge cylinder that runs through the bottom plate. A through hole is formed in the middle of the bottom plate for installing the discharge cylinder, and the bottom end of the discharge cylinder is detachably connected to a valve. The two ends of the discharge cylinder are respectively connected to the hopper scale and the valve by bolts. The top end of the hopper scale is detachably connected to a top cover, and one side of the top cover is provided with a feeding port that is connected to the hopper scale. The detachable connection has a motor, and the bottom end of the motor is connected to the top cover through bolts. The motor is connected and drives a rotating shaft that extends into the hopper scale, The top of the rotating shaft is connected to the top cover through a bearing, and the rotating shaft is detachably connected with two symmetrical positioning sleeves. The two positioning sleeves are connected to the rotating shaft key and fixed by bolts. The outer walls of the two positioning sleeves are equipped with several ring-shaped support rods. The outer side of the rotating shaft is equipped with several ring-shaped sail plates. The two ends of the sail plates are respectively detachably connected to the ends of the support rods on the outer side of the two positioning sleeves. The support rods on the outer side of the two positioning sleeves correspond uniformly, and the sail plates are set between the two corresponding support rods on the upper and lower sides. They are fixed by bolts, and can be erected by cooperating with the bottom plate through the support frame. The material to be mixed is added to the hopper scale from the feeding port, and then the material inside the hopper scale is measured by the weighing module. Weighing is carried out to facilitate the measurement of incoming and outgoing materials, and is coordinated by a positioning sleeve, sail board, and support rod, The mixing structure that constitutes the cage expands the mixing area and is driven by a motor to rotate the shaft. Then, the positioning sleeve and support rod are used to drive the sail to mix the materials in the hopper scale, improving the mixing efficiency and quality of the materials.
