All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 and fig. 2, in an embodiment of the present invention, a metering color master batch mixer includes: feeding zone 1, measurement district 2, mixing stirring district 3 and support 4, feeding zone 1 includes a plurality of feeder hopper 11, and the below of feeder hopper 11 is connected with the measurement structure. An operator can put corresponding raw materials into the feed hopper 11 according to production requirements to automatically mix new materials, defective materials, color master batches or additives in proportion. Metering area 2 sets up in 4 tops of support, including box 20 and measurement structure, wherein the measurement structure includes L venturi tube 21, discharging pipe 22, measurement storehouse 23, ejection of compact slide 24 and measurement title 6, and wherein the top of L venturi tube 21 is passed through the screw thread and is connected with feeder hopper 11, and the one end that the feeder hopper 11 was kept away from to L venturi tube 21 is passed through the screw thread and is connected with vertical discharging pipe 22 of placing, the bottom and the measurement storehouse 23 of discharging pipe 22 are connected, the bottom and the ejection of compact slide 24 of measurement storehouse 23 rotate to be connected, the top surface at ejection of compact slide 24 is inlayed to measurement title 6. Mix stirring district 3 fixed connection in the below of support 4, including motor 31, agitator 32 and blending hopper 33, motor 31 fixed connection is on the lateral wall of blending hopper 33, agitator 32 is vertical to be placed and agitator 32 and motor 31's output coaxial coupling, the bottom of blending hopper 33 is arc and the bottom of blending hopper 33 is provided with discharge gate 34. The female machine of tradition look also drives stirring rod and stirring vane through motor 31 and mixes the stirring to the raw materials, but the stirring rod of tradition look female machine of mixing is vertical to be placed, and the stirring vane level is placed, and such structure though the accessible sets up multilayer stirring vane and stirs as far as possible and mix to each raw materials, but the raw materials of device bottom edge still is in the stirring blind area. The bottom of the mixing barrel 33 is arc-shaped, so that a stirring blind area at the bottom of the device can be avoided, and the bottom of the device can be matched with the shape of the stirring wheel 32, so that the space is fully utilized, and the stirring and mixing efficiency is improved. The stirring wheel 32 of the invention is vertically arranged, and the stirring wheel 32 is coaxially welded with a plurality of sub-wheels, under the drive of the motor 31, the stirring wheel 32 can turn over the raw materials from bottom to top without putting each raw material, thus ensuring the uniformity and sufficiency of mixing and improving the product quality to a certain extent.

The L-shaped pipe 21 is provided with a negative pressure machine 5 at the joint of the horizontal pipe and the vertical pipe. The L-shaped pipe 21 may be blocked due to the special structure thereof, the negative pressure machine 5 can suck out the raw material blocked in the horizontal pipe of the L-shaped pipe 21, and the sucked out raw material can fall into the metering bin 23 downwards under the action of gravity when passing through the discharge pipe 22, so that the problem of the blockage of the L-shaped pipe 21 can be effectively solved.

The working principle is as follows: an operator sets the weight of each raw material and the stirring and mixing time through the touch screen 9 according to actual needs, and after setting, the raw materials are put into the feed hopper 11 and the device is started; the raw materials fall from the feed hopper 11, and fall into the metering bin 23 through the L-shaped pipe 21 and the discharge pipe 22, when the reading of the metering scale 6 embedded on the discharge sliding plate 24 reaches a set value, the PLC 10 controls the second transmission mechanism 8 to push the circular baffle 81 to move downwards until the L-shaped pipe 21 is completely blocked; after the second transmission mechanism 8 stops operating, the first transmission mechanism 7 pushes the connecting frame 71 and the connecting rod 72 downwards under the control of the PLC 10, so that the discharging sliding plate 24 is opened downwards, and the raw materials can fall into the stirring area 3 along the discharging sliding plate 24; when a plurality of raw materials enter the mixing barrel 33, the PLC 10 controls the motor 31 to drive the stirring wheel 32 to rotate, the stirring wheel 32 and the sub-wheel coaxially welded with the stirring wheel turn the raw materials from bottom to top, and after the set mixing time is reached, the motor 31 stops operating under the control of the PLC 10. After mixing of the new material, the defective material, the color master or the additive, etc., the operator can connect the plastic extruding machine or the injection molding machine at the discharge port 34 according to the production requirement to perform the next plastic extruding or injection molding work. It should be emphasized that the second transmission mechanism 8 and the circular baffle 81 are arranged at one end of the horizontal pipe of the L-shaped pipe 21 close to the negative pressure machine 5, and when the reading of the scale 6 reaches the set value, the circular baffle 81 can immediately fall to block the raw material from entering. Compared with the traditional color master mixer, the circular baffle 81 is arranged on the horizontal pipe of the L-shaped pipe 21, the moving speed of the raw materials in the horizontal pipe is relatively low, so that the raw materials entering the discharging pipe 22 can be almost ignored at the moment that the circular baffle 81 falls, and the metering precision is greatly improved. The first transmission mechanism 7 and the second transmission mechanism 8 are devices that can perform reciprocating linear motion, such as an electric push rod and an air cylinder, and are not limited herein. An operator can select the language type of an operation interface besides controlling the negative pressure machine 5, the metering scale 6, the first transmission mechanism 7 and the second transmission mechanism 8 on the touch screen 9 through the PLC 10, so that the applicability of the invention is greatly improved.

Referring to fig. 3 and 4, a first power transmission mechanism 7 is connected to the side wall of the metering bin 23 through a bolt, a connecting frame 71 is rotatably connected to the bottom of the first power transmission mechanism 7, a connecting rod 72 is rotatably connected to the bottom of the connecting frame 71, and the bottom of the connecting rod 72 is rotatably connected to the discharging sliding plate 24. The connecting frame 71 is square, and the structure can ensure the transmission efficiency without influencing the passing of raw materials. The horizontal pipe of the L-shaped pipe 21 is provided with a second transmission mechanism 8, the bottom of the second transmission mechanism 8 is fixedly connected with a circular baffle 81 with the same inner diameter as the L-shaped pipe 21, and the horizontal pipe of the L-shaped pipe 21 is provided with a semicircular groove (not shown in the figure) for the circular baffle 81 to pass through. The circular baffle 81 matches the wall shape of the L-shaped tube 21, which ensures that no material will get through the gap after the circular baffle 81 has fallen.
