Description

Technical Field

[0001] The utility model relates to an extruder mixing and feeding device for chips and master batches, and relates to the technical field of particle mixing and feeding equipment, in particular to an extruder mixing and feeding device for chips and master batches. Background Art

[0002] Conventional mixing devices use a masterbatch machine, where chips and masterbatch are mixed before the masterbatch and chips are fed into the extruder together. Masterbatch machines achieve a uniform mix of chips and masterbatch, but are expensive and are only suitable for applications requiring high precision in masterbatch control.

[0003] In addition, after being extruded by the masterbatch injection machine, the masterbatch pipeline is obliquely downward to the center of the slicing pipeline. The masterbatch enters the slicing pipeline by gravity, and then enters the extruder together with the slices. The extruder will exhaust during the production process, and sometimes the exhausted gas will gather at the lower part of the masterbatch pipeline. When the gas pressure is high to a certain level, the masterbatch is not easy to enter the slicing pipeline, which will make the masterbatch discharge uneven and even block the material, resulting in different mixing ratios of slices and masterbatch in the extruder at different time periods, affecting the final product quality.

[0004] In view of the problems existing in the above-mentioned prior art, it is very necessary to research and design a new type of extruder mixing and feeding device for chips and masterbatches, so as to overcome the problems existing in the prior art. Summary of the Invention

[0005] According to the above-mentioned prior art, the existing masterbatch machine equipment is expensive, and the masterbatch extruded by the masterbatch injection machine carries the discharged gas which will gather in the lower part of the pipeline, which may make it difficult for the masterbatch to enter the pipeline, and may also easily cause uneven discharge, even blockage, uneven material mixing ratio, and affect product quality and other technical problems. Therefore, a chip and masterbatch extruder mixing and feeding device is proposed.

[0006] The technical means adopted by this utility model are as follows:

[0007] An extruder mixing and feeding device for chips and masterbatch comprises: a mixing device housing, a masterbatch feeding structure, a chip feeding structure, a discharge structure and internal parts of the mixing device;

[0008] Furthermore, a masterbatch feeding structure communicating with the interior of the mixing device housing is provided on one side of the upper portion of the mixing device housing;

[0009] Furthermore, a slice feeding structure communicating with the interior of the mixing device housing is provided on the top of the mixing device housing;

[0010] Furthermore, a discharge structure communicating with the interior of the mixing device housing is provided on one side of the upper portion of the mixing device housing;

[0011] Further, a mixing device internal is provided at the inner center of the mixing device housing;

[0012] Furthermore, a mixing device mixture outlet is provided at the bottom of the mixing device housing, for the mixture to be discharged from the outlet to enter the next process.

[0013] Furthermore, the internals of the mixing device are a frame structure made of panels;

[0014] Furthermore, the upper portion of the internal part of the mixing device is a conical structure, and the lower portion is a cylindrical structure;

[0016] Furthermore, a feeding through hole is provided at the top center of the mixing device housing, for the slices inputted by the slice feeding structure to enter the interior of the mixing device housing through the feeding through hole.

[0017] Furthermore, the masterbatch feeding structure includes: a functional masterbatch output pipe and a masterbatch inlet piece;

[0018] Furthermore, the pipe of the masterbatch inlet piece penetrates the outer shell of the mixing device and the inner part of the mixing device at a certain angle;

[0019] Furthermore, the top of the masterbatch inlet is connected to the functional masterbatch output pipe, and the bottom end of the pipe is placed at the center of the mixing device. The dried functional masterbatch enters the center of the mixing device through the functional masterbatch output pipe and the masterbatch inlet.

[0020] Furthermore, the slice feeding structure includes: a slice output pipe and a slice inlet piece;

[0021] Furthermore, the slice inlet is provided at the top of the mixing device housing, above the material discharge through hole;

[0022] Furthermore, the top of the slice inlet piece is connected to the slice output pipe through a flange.

[0023] Furthermore, the slice inlet and the mixing device inner part are arranged concentrically. The dried slices enter the mixing device housing through the slice output pipe and the slice inlet. They are evenly distributed to the upper part of the mixing device inner part by gravity, fall in an umbrella shape along the outer wall of the mixing device inner part, and mix with the masterbatch at the mixing device mixture outlet connected to the lower part of the mixing device housing. The mixture enters the next process through the mixing device mixture outlet.

[0024] Further, the discharge structure includes: a discharge port and a discharge valve;

[0025] Furthermore, the discharge port is provided on one side of the upper portion of the mixing device housing and communicates with the interior of the mixing device housing;

[0026] Furthermore, a discharge valve is provided on the discharge port pipeline. The discharge valve is opened during discharge. When the gas generated by the mixing or the gas from the next process affects the mixing effect, the discharge valve is adjusted to discharge the gas. The gas is discharged from the mixing and feeding device through the discharge port pipeline and the discharge valve.

[0027] Furthermore, a window is fixed on the side of the mixing device housing by bolts, for observing the mixing and feeding of chips and masterbatch through the window.

[0028] Compared with the prior art, the utility model has the following advantages:

[0029] 1. The extruder mixing and feeding device for chips and masterbatch provided by the utility model has a simple and practical structure, low manufacturing cost, and is suitable for use in various occasions;

[0030] 2. The extruder mixing and feeding device for chips and masterbatches provided by the utility model is provided with a discharge structure. The gas discharged from the extruder during the production process will be discharged through the exhaust valve on the upper part of the device.

[0031] In summary, the application of the technical solution of the utility model solves the problems in the prior art that the existing masterbatch machine equipment is high in price, the masterbatch extruded by the masterbatch injection machine carries the discharged gas which will accumulate in the lower part of the pipeline, which can easily lead to the masterbatch being difficult to enter the slicing pipeline, and can also easily cause uneven masterbatch discharge and even blockage, resulting in uneven material mixing ratios in different time periods, affecting product quality and other problems.
