Description

Technical Field

[0001] This utility model relates to the field of mixed production technology, specifically to a calcium powder plastic mixing system. Background Technology

[0002] The existing technology involves mixing calcium masterbatch and plastic in a mixing device before feeding. Since both are particulate matter, the mixing is uniform. However, calcium masterbatch is expensive, so calcium powder is considered as a substitute.

[0003] However, if calcium powder is used instead, since calcium powder is in powder form, if it is directly added to the plastic, the calcium powder will all accumulate at the bottom of the mixing device, thus making it impossible to feed the material evenly.

[0004] Therefore, it is necessary to propose a calcium powder and plastic mixing system that is suitable for the mixed transportation of calcium powder and plastic, and achieves uniform feeding of calcium powder and plastic. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and propose a calcium powder and plastic mixing system that is suitable for the mixed transportation of calcium powder and plastic, and achieves uniform feeding of calcium powder and plastic.

[0006] The purpose of this utility model is achieved through the following technical solution: a calcium powder plastic mixing system, including a mixing tank, a double spiral conveying device connected to the lower side of the mixing tank, and a first conveying device and a second conveying device for feeding calcium powder and plastic into the mixing tank.

[0007] The first conveying device includes a first storage tank, and the bottom of the first storage tank is connected to a screw lifting component whose outlet is connected to a mixing tank.

[0008] The lifting member is provided with a first sprocket for driving its operation. The first sprocket is connected to a second sprocket via chain drive. The second sprocket is connected to a first motor for driving its rotation.

[0009] The second conveying device includes a second storage tank, and a screw conveyor with an outlet connected to a mixing tank is provided at the lower end of the second storage tank. A second motor for driving the screw conveyor is provided on the screw conveyor.

[0010] The double-helix conveying device includes a hollow body with an inlet and an outlet connected to the mixing tank. Two parallel spiral rods rotate inside the body, and a third motor is provided on the body to drive the two spiral rods to rotate in opposite directions.

[0011] The output end of the third motor is provided with a first gear, and a second gear and a third gear are respectively meshed on both sides of the first gear. The second gear and the third gear are respectively connected to two screw rods for transmission.

[0012] A speed-changing assembly is provided between the second gear and one of the helical rods. The speed-changing assembly includes two parallel fourth gears and a fifth gear. A sixth gear meshes with the fourth gear, and a seventh gear connected to the sixth gear meshes with the fifth gear. An input rod connected to the second gear rotatably passes through the fourth gear, and an output rod connected to the helical rod is provided on the fifth gear. A synchronous shaft detachably connected to the fourth and fifth gears is slidably sleeved at the end of the input rod located between the fourth and fifth gears. The ratio of the fourth gear to the sixth gear and the ratio of the fifth gear to the seventh gear are not equal.

[0013] A collar is rotatably sleeved on the synchronous shaft, and a through groove is provided on the main body. A slider is slidably disposed on the through groove, and the slider is connected to the collar.

[0014] The beneficial effects of this utility model are: by setting up a double spiral conveying device, calcium powder and plastic are conveyed by the double spiral, and they are evenly mixed in each section during transportation, thereby achieving uniform feeding of calcium powder and plastic. Compared with uniform feeding of calcium masterbatch and plastic, the cost is greatly reduced. Attached Figure Description

A first sprocket 33, connected only to the screw, is rotatably mounted at one end of the screw lifting member 32. The first sprocket 33 is connected to a second sprocket 35 via a chain 34. A first motor 36 is connected to the second sprocket 35 to drive its rotation. When the first motor 36 operates, the screw lifting member 32 transports the calcium powder (plastic) stored in the first storage tank 31 to the mixing tank 1.

A second motor for driving the screw to rotate is provided at one end of the screw conveyor 42. When the second motor is working, the screw conveyor 42 transports the plastic (calcium powder) stored in the second storage tank 41 to the mixing tank 1.

[0021] The double-helix conveyor 2 includes a hollow body 21. An inlet 22 communicating with the mixing tank 1 is located on the upper side of the body 21, and an outlet 23 is located on the lower side of the body 21.
