[0002] Masterbatch, also called color seed, is a new type of colorant for polymer materials, also known as pigment preparation. After the masterbatch is cut into pellets, it needs to be packaged and the masterbatch is put into packaging bags in equal amounts. Most of the existing packaging mechanisms feed the material through a conveyor belt, then weigh the masterbatch through a weighing device, and then put the weighed masterbatch into the packaging bag.

[0003] Although this packaging mechanism can package the masterbatch quantitatively with relative accuracy, the packaging process is cumbersome and inefficient due to the need to frequently weigh the masterbatch. Utility Model Content

[0007] The first servo motor drives the first screw rod to rotate, and then the rotating first screw rod and the fixed frame cooperate with each other to drive the movable plate to adjust the position, thereby adjusting the position of the entire quantitative component, so that the top of the top cover is located below the top of the fixed cylinder, and the second servo motor drives the second screw rod to rotate, and the rotating second screw rod drives the bottom cover to move, adjust the distance between the bottom cover and the top cover in the fixed cylinder, cooperate to add masterbatch from the top cover to the fixed cylinder, and weigh the quantitative masterbatch through the bottom cover with a weighing sensor, so that the quantitative ingredients are consistent with the space between the bottom cover and the top cover in the fixed cylinder. After each quantitative weighing and batching, the first servo motor drives the entire quantitative component to move downward, so that the bottom cover is moved out of the fixed cylinder, and the discharge after batching can be completed.

[0008] Preferably, the output shaft of the first servo motor is connected and fixed to the top end of the first screw rod.

[0009] The output shaft of the first servo motor drives the first screw rod to rotate.

[0010] Preferably, the movable plate is threadedly connected to the first screw rod, and the movable plate forms a sliding fit with the fixed frame.

[0011] The rotating first screw rod and the fixing frame cooperate with each other to drive the movable plate to adjust the position.

[0012] Preferably, sliding rods are fixed to the inner walls at both ends of the connecting frame, and the sliding rods are plugged and slidably connected with the adjustment plate.

[0013] The slide bar cooperates with the connecting frame so that the adjusting plate can move in the vertical direction along the connecting frame.

[0014] Preferably, a feed hole is opened on the top of the top cover, and a plug is inserted into the feed hole, and the top cover is screwed to the second screw rod.

[0015] A certain amount of masterbatch can enter between the top cover and the bottom cover through the feed hole.

[0016] Preferably, the top of the bottom cover is a conical slope, and a weighing sensor is installed at the bottom of the bottom cover.

[0017] The conical slope of the bottom cover 16 facilitates the downward discharge of the masterbatch on the top, and the masterbatch on the top of the bottom cover 16 can be weighed by a weighing sensor.

[0018] The beneficial effects of the utility model are:

[0019] The height position of the entire quantitative component is adjusted by the first servo motor so that the top of the top cover is located below the top of the fixed barrel, and the second servo motor is used to adjust the distance between the bottom cover and the top cover in the fixed barrel, and then the bottom cover with a weighing sensor is used to weigh the quantitative masterbatch so that the quantitative ingredients are consistent with the space between the bottom cover and the top cover in the fixed barrel. After each quantitative weighing and batching, the first servo motor drives the entire quantitative component to move downward so that the bottom cover is moved out of the fixed barrel, and the discharge after batching can be completed, which effectively solves the problem in the prior art that the masterbatch needs to be weighed frequently, resulting in a cumbersome and inefficient packaging process and a complex equipment structure.
