Description

Technical Field

[0001] The utility model relates to the technical field of discharging equipment, in particular to a quantitative discharging equipment for polyvinyl chloride particles. Background Art

[0002] Existing polyvinyl chloride particles, referred to as PVC particles, are high-molecular polymer particles formed by free radical polymerization of vinyl chloride monomer. In the process of plastic molding, polyvinyl chloride particles are needed as raw materials. Quantitative discharge is a key link to ensure production continuity and product quality.

[0003] During the quantitative discharge process, the PVC particles need to enter the interior of the hopper first. During the feeding process, due to the influence of speed or gravity, the PVC particles will have a continuous impact on the inner wall of the hopper, causing wear on the hopper surface. When the hopper is excessively worn, the feed needs to be replaced or repaired. Repairing the entire hopper results in high maintenance costs and long downtime. Utility Model Content

At this time, the limiting plate 5 is pushed so that the limiting plate 5 fits on the upper surface of the hopper 1 and the built-in plate 2. At this time, the limiting screw 8 is rotated so that the limiting screw 8 fits tightly on the inside of the limiting plate 5 to fix the limiting plate 5.

At this time, clamp the handle 10 inside the card slot 9 and rotate the limit screw 8 so that the limit screw 8 fits tightly inside the limit plate 5 to fix the limit plate 5. At this time, the built-in plate 2 is installed. When the built-in plate 2 is worn to a certain extent, a new built-in plate 2 can be quickly replaced without replacing the entire hopper 1, thereby reducing maintenance costs and downtime. At the same time, according to the different characteristics of polyvinyl chloride particles, users can choose built-in plates 2 of different materials to achieve the best protection effect;

[0028] The second step is to release the connection between the handle 10 and the card slot 9. At this time, pull the pressure plate 12 upward. At this time, the spring 13 is stretched. At this time, the handle 10 is slidably connected to the inside of the fixed slot 11. At this time, release the pressure plate 12. Under the action of the spring 13, the pressure plate 12 slides upward so that the pressure plate 12 is slidably connected to the outside of the handle 10. At this time, the handle 10 is stored.
