[0031] Please refer to Figures 1-7 This utility model provides a convenient particle metering mechanism, including a measuring cup holder 1, a measuring cup 2, an adjusting block 3, an adjusting screw holder 4, an adjusting handwheel 5, an adjusting spring 6, a material buffer bin 7, a hopper baffle 8, a viewing window 9, a buffer hopper receiving hopper 10, an electric cylinder connecting plate 11, an electric cylinder front cover 12, an electric cylinder 13, a measuring cup cover 14, a suction box 15, a sliding hopper 16, and a measuring cup fixing support 17.
[0032] A square slot is provided on the measuring cup holder 1, and the measuring cup 2 is installed in the square slot and reciprocates along the direction of the slot. The measuring cup holder 1 has an inlet at the top and an outlet at the bottom. The measuring cup 2 has a trapezoidal slot that is wider at the top and narrower at the bottom, with a threaded hole at the center of the trapezoidal slot end face connecting to the adjusting thread seat 4. The size of the adjusting block 3 corresponds to the size of the trapezoidal slot on the measuring cup 2, and it can move back and forth within the trapezoidal slot. The center of the trapezoidal end face of the adjusting block 3 has a threaded hole connecting to the adjusting handwheel 5, forming a whole. Under the action of the adjusting thread seat 4, the adjusting handwheel 5, and the adjusting spring 6, the adjusting block 3 moves back and forth along the adjusting thread seat 4 in the direction of tension of the threaded hole in the measuring cup 2, forming an adjustable cavity between itself and the measuring cup 2. By rotating the adjusting thread seat 4, the position of the adjusting block 3 can be changed, thereby changing the volume of the cavity.
[0033] The measuring cup 2, adjusting block 3, adjusting screw seat 4, adjusting handwheel 5, and adjusting pressure spring 6 together constitute a measuring cup feeding mechanism.
[0034] The material buffer bin 7 is equipped with a discharge port, which corresponds to the inlet above the measuring cup holder 1. The sliding hopper 16 is equipped with an inlet, which corresponds to the outlet below the measuring cup holder 1, and the size of the inlet of the sliding hopper 16 is larger than the outlet below the measuring cup holder 1.
[0035] The material buffer bin 7 is provided with a slot and is connected to a bin baffle 8. The bin baffle 8 can adjust the relative position of the material buffer bin 7 discharge port along the slot direction to achieve the size adjustment of the material buffer bin 7 discharge port.
[0036] The material buffer bin 7 is also equipped with a viewing hole, through which the product status inside the material buffer bin 7 can be observed.
[0037] Above the material buffer bin 7, a buffer material receiving hopper 10 is connected by a hinge, which is used to receive and temporarily store products to be packaged.
[0038] The electric cylinder connecting plate 11 has holes for connecting to the electric cylinder front cover plate 12 and the electric cylinder 13, respectively. The piston rod of the electric cylinder 13 is connected to the measuring cup 2, driving the measuring cup 2 to reciprocate along the square slot. The electric cylinder front cover plate 12 covers the outside of the electric cylinder 13, providing protection and support.
[0039] The measuring cup cover 14 is connected to the upper surface of the measuring cup holder 1 through the threaded holes around the top, protecting the measuring cup 2 and related components from the influence of the external environment.
[0040] The suction box 15 is fixedly connected to the side of the measuring cup holder 1, and its end is provided with a suction port. This suction port faces the movement trajectory of the measuring cup 2 and is connected to a negative pressure generator or dust collector. During the reciprocating motion of the measuring cup 2, the suction box 15 sucks away the dust and debris generated by particle friction, ensuring the cleanliness of the measurement process and avoiding the impact of dust accumulation on measurement accuracy. The sliding hopper 16 receives the discharge port of the measuring cup holder 1, ensuring that the material slides smoothly into the packaging mechanism.
[0041] In summary, the working principle of this utility model embodiment of a convenient particle metering mechanism is as follows: The entire system consists of a measuring cup holder 1, a measuring cup 2, an adjusting block 3, an adjusting screw seat 4, an adjusting handwheel 5, an adjusting spring 6, a material buffer bin 7, a bin baffle 8, a viewing window 9, a buffer bin receiving hopper 10, an electric cylinder connecting plate 11, an electric cylinder front cover 12, an electric cylinder 13, a measuring cup cover 14, a suction box 15, a sliding hopper 16, and a measuring cup fixing support 17. The product enters the material buffer bin 7 through the buffer bin receiving hopper 10, and then enters the cavity of the measuring cup discharging mechanism. Driven by the electric cylinder 13, the measuring cup 2 reciprocates, feeding the product in the cavity through the discharge port into the sliding hopper 16, where it slides into the packaging mechanism. By adjusting the rotation of the adjusting screw seat 4, the change in cavity volume can be controlled, thereby achieving precise adjustment of the product weight.
[0042] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
