[0002] The powder feeding mechanism is a material feeding mechanism used for packaging machinery to disperse and transport the materials. The existing powder feeding mechanism includes a powder delivery mechanism and a powder conveying mechanism. After the powder enters the hopper body, it is dispersed through multiple groups of pipelines. Each group of pipelines is equipped with a servo motor to drive a spiral feeding group. The spiral rod in the spiral feeding group rotates, driving the powder to be transmitted downward along the pipeline to the powder transmission mechanism, and the powder enters the material bag along the conveying pipe in the conveying mechanism.

[0003] The above-mentioned prior art has the following problems: 1. During the filling process, the powder material will be affected by factors such as the material surface height and pressure difference in the hopper, resulting in large fluctuations in the weight deviation of the powder output at the terminal, resulting in defective products. 2. When replacing powder products, the pipeline needs to be cleaned. The pipeline disassembly and installation of the prior art are inconvenient, affecting the production time. 3. The spiral feeding group of the prior art is mostly filled with a long screw, which is difficult to process and has high cost. Summary of the invention

[0004] The purpose of the utility model is to solve the above existing problems and provide a powder feeding mechanism with good material weight consistency and convenient equipment disassembly and assembly.

[0005] The utility model is implemented as follows: a powder feeding mechanism includes a powder delivery mechanism and a powder conveying mechanism, the first support frame of the powder delivery mechanism is connected to a silo group, the silo group is connected to a spiral feeding group and a hopper body, and the spiral feeding group is connected to a motor group. A first bearing is installed on the second support frame of the powder conveying mechanism, a transmission shaft is installed in the first bearing, a synchronous pulley, a first servo motor, and a first coupling are installed on the transmission shaft, a connecting frame is connected to a synchronous belt, a connecting frame is connected to a bracket of a conveying pipe, and a synchronous belt is installed on the synchronous pulley.

[0006] Furthermore, the hopper is installed on the third support frame of the hopper body, the hopper is installed on the stirring frame through the first linear bearing, the hopper is connected with a pipeline, the cylinder is installed on the third support frame, and the rod of the cylinder is connected to the stirring frame through the bracket.

[0007] Furthermore, a guide shaft and a second bearing are installed on the fourth support frame of the motor group, and a second linear bearing and a nut are installed on the first mounting plate. The upper part of the screw connected to the handwheel cooperates with the second bearing, and the lower part cooperates with the nut. The position of the first mounting plate can be adjusted, and the second servo motor is installed on the first mounting plate.

[0008] Furthermore, the lower end of the spiral rod of the spiral feeding group is connected to the stop plate, the upper end of the spiral rod is installed with a second coupling, and a limit ring, a third bearing, a spiral rod, a stirring rod, and a sealing gasket are installed on the spiral rod.

[0009] Furthermore, the small silo of the silo group is equipped with an observation plate, a connecting pipe and a bearing seat are installed on the upper part of the small silo, and a limit block and a feed pipe are installed on the lower part of the small silo.

[0010] Furthermore, the mounting frame of the first support frame is installed with a slide rail, the slider is installed on the slide rail and slides therewith, the second mounting plate is connected to the slider, and the second mounting plate is installed with a limit plate and a pin shaft.

[0011] The advantages of the utility model are:

[0012] After the powder enters the hopper, it is dispersed into each small silo through multiple sets of pipelines to eliminate material pressure fluctuations, so that the weight of the powder entering the bag is stable and the consistency is good.

[0013] At the same time, the small silo is easy to disassemble and clean. You only need to loosen the coupling and rotate the handwheel to lift the multiple servo motors to make room. Loosen the limit plate and pull the silo group to separate the silo group and the spiral feeding group from the pin shaft to complete the disassembly for subsequent cleaning.

[0014] The spiral rod used is used in conjunction with the silo group and the powder conveying mechanism to complete the powder transmission. The conveying pipe of the powder conveying mechanism can extend into the material bag and be driven by a servo motor to move up and down with the material bag. It can replace the long spiral rod and directly insert it into the material bag to convey the powder. The shorter spiral rod replaces the long spiral rod, which reduces the difficulty of bolt rod processing and reduces processing costs. BRIEF DESCRIPTION OF THE DRAWINGS
