Technical Field

[0001] This invention belongs to the field of mechanical technology and relates to a defective product ejection and replenishment device. Background Technology

[0002] Zongzi is a food made by wrapping glutinous rice in bamboo leaves and steaming it. The main ingredients are glutinous rice and fillings, and it is wrapped in bamboo leaves (or reed leaves, eucalyptus leaves, etc.).

[0003] In order to automate the production of zongzi (sticky rice dumplings), it is necessary to weigh the materials wrapped in bamboo leaves in a quantitative manner. After the materials are automatically added to the feeding cup, the cups that do not meet the weight requirements need to be rejected a second time before the materials are added. Therefore, it is necessary to design a defective product ejection and replenishment device. Summary of the Invention

Two elastic guide plates are installed at the working port of one end of the temporary storage cylinder. The sealing door is located at an auxiliary port at one end of the temporary storage cylinder and is connected to a control structure that can drive it to open and close. An electronic scale is installed inside the temporary storage cylinder, and a limiting block is also installed inside the temporary storage cylinder. A cylinder three is installed on the limiting block, and an ejector block is connected to the piston rod end of the cylinder three. The material box is arranged on the side of the temporary storage cylinder and is connected to a feeding pipe. A screw is horizontally rotatably installed inside the feeding pipe, and the end of the screw is connected to a power motor two that can drive it to rotate. The feeding pipe has a downward-facing discharge port, and the temporary storage cylinder also has an opening. One end of the feeding hopper is inserted into the opening, and the other end of the feeding hopper is located directly below the storage port. The feeding hopper is also connected to a mounting frame through several first springs, and the mounting frame is fixed to the side of the temporary storage cylinder.

[0007] The feeding hopper is arranged at an angle.

[0008] A fixing plate is connected to the mounting frame. A guide post is vertically mounted on the fixing plate. A guide sleeve is slidably connected to the guide post. A linkage beam is installed between the guide sleeves. The linkage beam has an impact member that cooperates with the feeding hopper. A drive motor is also mounted on the fixing plate.

Using the action of cylinder one and cylinder two, the rejection block removes the material cup from the chain conveyor belt and pushes it into the temporary storage cylinder. The material is replenished into the cup by different vibration amplitudes of the feeding hopper. Subsequently, the ejector block is driven by cylinder three to send the cup with the correct amount of material back to the chain conveyor belt. The replenishment is accurate and convenient.
