Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastic processing, in particular to a mixed masterbatch automatic feeding device. Background Art
[0002] With the continuous development of the plastics industry, plastic products are increasingly used in various fields, from daily necessities to industrial components, from building materials to electronic device casings. The demand for color diversity and coloring quality of plastic products is also increasing. Masterbatch is a new type of colorant specially made for polymer materials. It is composed of three basic elements: pigment or dye, carrier, and additive. Mixed masterbatch can provide richer color effects and special properties (such as fluorescence, pearlescent effects, or enhanced weather resistance). This has prompted the development of automatic feeding equipment. Existing automatic feeding equipment has some shortcomings. First, uneven mixing can cause the color of the final plastic product to appear mottled, streaked, or chromatic aberration, resulting in areas of varying shades of color on the film, seriously affecting the product's appearance quality and reducing its market competitiveness. Second, masterbatch easily remains, making cleaning inside the equipment difficult. Residual masterbatch may deteriorate and clump, affecting the quality of the next feeding and contaminating the next batch of masterbatch. It is easy to cause material blockage and affect the continuity of feeding. To address the above problems, we have proposed an automatic feeding equipment for mixed masterbatch. Utility Model Content

[0027] Specifically, the clean water is introduced into the first water delivery rod 18 and the second water delivery rod 38 by rotating the rod 2, and finally sprayed out through multiple groups of water delivery nozzles 19, thereby cleaning the components in the shell 1, removing residual masterbatches and impurities, preventing contamination between different masterbatches, and preparing for the next production.
[0028] In this embodiment, the outer wall of the shell 1 is provided with multiple groups of holes in a circular array and are all fixedly connected to the conveying pipe 13.

The mixed masterbatch is discharged through the discharge pipe 25. The inclination of the guide bin 24 and the spiral conveying device ensure that the masterbatch can be discharged smoothly without clogging or leakage.
[0034] It should be noted that the present invention is a mixed-type masterbatch automatic feeding device. The user pours the required masterbatch of different colors into different feeding barrels 17. The masterbatch in multiple groups of feeding barrels 17 moves to the inside of the conveying pipe 13 under the action of gravity. At this time, the operation of multiple groups of first motors 14 drives the first transmission shaft 15 to rotate, so that the first spiral blade 16 drives the masterbatch to move to the inside of the shell 1. The speed and flow of the discharge can be adjusted by spiral conveying, so as to control the quantity. When the masterbatch of different components is respectively introduced into the inside of the shell 1 through the conveying pipe 13, the masterbatch is fed to the shell 1 through the conveying barrel 13.

The rotation of the rotating rod 2 drives the second transmission shaft 27 to rotate, so that the second spiral blade 28 moves the mixed masterbatch downward. Conveying, at the same time, in this process, the rotation of the second transmission shaft 27 and the second spiral blade 28 has a certain stirring and mixing effect on the masterbatch, and the mixed masterbatch is discharged through the discharge pipe 25. The inclination of the guide bin 24 and the spiral conveying device ensure that the masterbatch can be discharged smoothly without clogging or leakage. When different colors or types of products are to be produced subsequently, the equipment needs to be cleaned. At this time, the rotation of the rotating rod 2 drives the support rod 35 to rotate, thereby driving the cleaning rod 36 to rotate, so that multiple groups of cleaning strips 37 clean the inside of the shell 1. At the same time, the cleaning strip 37 is a soft silicone The cleaning rod 36 and the cleaning strip 37 are made of rubber material to prevent scratching the inside of the shell 1. Moreover, when the masterbatch is being mixed inside the shell 1, the rotating cleaning rod 36 and the cleaning strip 37 also prevent the masterbatch from adhering to the inner wall of the shell 1. When there is no masterbatch in the shell 1, the clean water is transmitted to the rotating rod 2 through the connecting pipe 33 through the operation of the water tank 34, and is then transmitted to the first water delivery rod 18 and the second water delivery rod 38, and finally sprayed out through multiple groups of water delivery nozzles 19, thereby cleaning the internal parts of the shell 1, removing residual masterbatch and impurities, preventing contamination between different masterbatches, and preparing for the next production.
