Description

Technical Field

[0001] This utility model relates to the field of vacuum feeding machine technology, specifically to a feeding device for an automatic vacuum feeding machine. Background Technology

[0002] Automatic vacuum feeders, as a highly efficient automated material conveying equipment, have been widely used in many industrial fields such as chemical industry, food processing, pharmaceutical manufacturing, and plastic molding due to their advantages such as no need for manual intervention, cleanliness and pollution-free operation, and small footprint. They are mainly used for conveying powder, granular and small block materials.

[0003] In actual production processes, materials often clump together to varying degrees due to factors such as changes in storage humidity, prolonged storage time, and pressure. For example, flour and starch in the food industry are prone to clumping due to moisture, while some powder raw materials in the chemical industry can form agglomerates due to electrostatic adsorption. Since the diameter of the suction nozzle is fixed, it is difficult to suck up large clumps of material, which can easily accumulate and block the suction port. Once a blockage occurs, it will not only cause the feeding process to be interrupted, affecting the continuity of the production line, but also require machine shutdown for manual cleaning, increasing labor intensity and production progress. Therefore, an automatic vacuum suction machine feeding device is proposed to solve the above problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please refer to Figure 1-3 As shown, this utility model provides a feeding device for an automatic vacuum feeding machine, including a hopper 1 and a suction port 2. The suction port 2 is connected to the lower end of the hopper 1. An installation plate 4 is installed on the upper surface of the hopper 1. A stirring device is installed inside the hopper 1. A support component is installed at the bottom of the stirring device. A suction pipe 3 is connected to the lower end of the suction port 2. A crushing device is installed inside the suction port 2.

[0020] Specifically, this utility model uses a servo motor 5 to drive the stirring rod 6 to rotate, and the stirring blades 9 to stir the material in the hopper 1, which can initially disperse the agglomerated material and prevent the material from accumulating in the hopper 1. The rotating motor 14 also drives the rotating shaft 12 and the crushing disc 11 to rotate, and the crushing disc 11 can crush the agglomerated material in a secondary manner, so that the material can pass smoothly through the suction port 3 and then be transported to the vacuum feeder, avoiding blockage and improving the continuity and stability of feeding. The staggered distribution of the stirring blades 9 can improve the stirring and dispersion effect and the material flowability. The circular array distribution of the crushing discs 11 ensures comprehensive crushing. The baffle 13 assists in guiding the material and leaves gaps to prevent accumulation, which can work with the vacuum feeder to stably feed the material.

[0021] The support assembly includes a stirring support rod 7 and a first bearing 8. Multiple sets of stirring support rods 7 are arranged evenly around the inner wall of the hopper 1. One end of the rod is fixedly installed on the inner wall of the hopper 1. The first bearing 8 is located at the lower end inside the hopper 1 and is also fixedly installed at the other end of the stirring support rod 7. The support rods 7 and the first bearing 8 can provide support for the stirring rod 6.

[0022] The mixing device includes a servo motor 5, a mixing rod 6, and mixing blades 9. The servo motor 5 is fixedly mounted on the upper surface of the mounting plate 4. The output end of the servo motor 5 passes through the mounting plate 4 and is connected to the upper end of the mixing rod 6. The mixing rod 6 is located at the center inside the hopper 1. Multiple sets of mixing blades 9 are arranged and are staggered on the surface of the mixing rod 6. The lower end of the mixing rod 6 is rotatably mounted inside the first bearing 8. By starting the servo motor 5, the mixing rod 6 is driven to rotate. The rotation of the mixing rod 6 drives the multiple sets of mixing blades 9 to rotate, thereby stirring the material inside the hopper 1, initially dispersing the agglomerated material, and preventing the material from containing a large amount of agglomerated material, which could lead to blockage.

[0023] The crushing device includes a crushing disc 11, a rotating shaft 12, and a rotating motor 14. Multiple sets of crushing discs 11 are evenly arranged on the surface of the rotating shaft 12. The rotating shaft 12 is rotatably installed inside the suction port 2. The rotating motor 14 is located on one side of the suction port 2, and its output end passes through the suction port 2 and is connected to one end of the rotating shaft 12. By starting the rotating motor 14, the rotating shaft 12 is driven to rotate. The rotation of the rotating shaft 12 drives the multiple sets of crushing discs 11 to rotate. The rotation of the crushing discs 11 further crushes the materials that are agglomerated during the flow process.

[0024] Among them: baffles 13 are installed between multiple crushing discs 11, and a second bearing 10 is installed on the inner wall of one side of the suction port 2. One end of the rotating shaft 12 is rotatably installed inside the second bearing 10. The baffles 13 can drive the material flow and prevent material accumulation.

[0026] Working Principle: This utility model is a feeding device for an automatic vacuum feeder. First, the material is poured into the hopper 1, and the suction pipe 3 is connected to the pipeline of the vacuum feeder. Then, the servo motor 5 is started to drive the stirring rod 6 to rotate. The rotation of the stirring rod 6 drives multiple sets of stirring blades 9 to rotate, thereby stirring the material inside the hopper 1, initially dispersing the lumpy material, and preventing the material from containing a large number of lumps that could cause blockage. Then, the suction force generated by the vacuum feeder sucks the material out of the hopper 1. When the material passes through the suction port 2, the rotating motor 14 is started to drive the rotating shaft 12 to rotate. The rotation of the rotating shaft 12 drives multiple sets of crushing discs 11 to rotate. The rotation of the crushing discs 11 further crushes the lumpy material that is flowing. At the same time, baffles 13 are installed between the multiple sets of crushing discs 11 to promote the flow of material and prevent material accumulation. The crushed material is transported into the vacuum feeder through the suction pipe 3 by the suction force of the vacuum feeder.
