Problems solved by technology
[0004] Since a part of the material with a low melting point adheres to the feeder of the twin-screw extruder after melting, the proportion of each component in the actual formula is seriously inconsistent with the proportion of each component set, which affects the product quality and even produces a large amount of scrap.
The material adheres to the screw barrel and screw of the feeder, and is subjected to long-term friction and heat generation by the feeding screw and screw barrel, resulting in material degradation and quality accidents such as product discoloration
If it is not discovered in time, it is bound to cause heavy losses to customers

Embodiment Construction
[0029] The following combination figure 1 , a preferred embodiment of the present invention is described in detail.
[0030] Such as figure 1 as shown, figure 1 It is a structural schematic diagram of a twin-screw extruder feeding device for preventing agglomeration of mixed materials provided by the present invention.
[0031] A feeding device for a twin-screw extruder that prevents agglomeration of mixed materials includes a feeding transmission mechanism 1 and a feeding cooling mechanism 3 . The feeding transmission mechanism 1 is in transmission connection with the feeding cooling mechanism 3. The feeding cooling mechanism 3 is filled with the mixed material 2 continuously fed by the feeding transmission mechanism 1 and the feeding cooling mechanism 3. The feeding cooling mechanism 3 will feed The mixed material 2 is cooled and sent to the extrusion equipment.
[0032] The feeding transmission mechanism 1 includes a driving motor 11 , a screw barrel 12 , and a twin scr...

A feeding device for a twin-screw extruder that prevents agglomeration of mixed materials includes a feeding transmission mechanism and a feeding cooling mechanism. The feeding transmission mechanism is connected with the feeding cooling mechanism. The feeding cooling mechanism is filled with the mixed material that is continuously fed through the feeding transmission mechanism and the feeding cooling mechanism. The feeding cooling mechanism cools the fed mixed material and transports it to the extrusion equipment. The advantages of the present invention are: the present invention is simple in structure, easy to configure, easy to operate and use, can fully block the transmission of the production environment temperature to the mixed material, and can take away the heat of the feeder hopper and screw barrel of the twin-screw extruder, reducing the temperature. , to avoid the agglomeration of the mixture caused by low melting point components and additives in the formula due to high ambient temperature, it is an ideal twin-screw extruder feeding device to prevent the agglomeration of the mixture, and can be expanded to similar Solid low melting point or processing feed containing solid low melting point.
Description
technical field [0001] The invention relates to a feeding device, in particular to a feeding device for a twin-screw extruder which prevents agglomeration of mixed materials. Background technique [0002] Low-melting additives or resins are often used in modified plastic formulation components, but during the modified production process, the heat conduction of the feeder through the barrel of the twin-screw extruder will cause the low-melting substance to melt and adhere to the Storage tanks and feeders. After a long production time, the material agglomerates, resulting in unstable product performance. The agglomeration of the mixed material in the feeder of the twin-screw extruder causes production interruption, and it must be cleaned before continuous production. This will not only delay production, waste costs, and even cause unqualified finished products. [0003] At present, the feeder of the twin-screw extruder in the prior art generally adopts screw feeding, and the...
