Description

Technical Field

[0001] The utility model relates to the technical field of material mixing, in particular to a material mixer. Background Art

[0002] Color masterbatch is a pre-dispersed pigment or dye used for coloring plastic products, usually composed of pigment, carrier resin, and some additives. They are added to colorless or natural plastic raw materials during plastic processing to achieve the desired color and performance.

[0003] In order to ensure that the color masterbatch is evenly dispersed in the plastic raw materials and avoid problems such as color spots and color differences, it is necessary to ensure that the color masterbatch is evenly dispersed in the plastic raw materials to avoid problems such as color spots and color differences. At the same time, uniform color distribution helps to improve the appearance quality and performance of the product.

[0004] When mixing the color masterbatch, it is necessary to ensure that the mixing equipment (such as a high-speed mixer) is clean and free of foreign matter to avoid contamination or color error. According to the product formula requirements, the required color masterbatch and plastic raw materials should be accurately weighed, and the color masterbatch and plastic raw materials should be properly dried during mixing to remove surface moisture. During the operation, first put the plastic raw materials into the mixer, start the mixer to evenly disperse, then gradually add the color masterbatch, and adjust the mixer to an appropriate speed for high-speed mixing to ensure that the color masterbatch and the plastic raw materials are fully mixed. After stirring for a period of time, take a small amount of sample to check whether the color is uniform. If necessary, the amount of color masterbatch added or the mixing time can be appropriately adjusted.

[0005] Chinese utility model patent: Publication number CN207983753U discloses a color masterbatch stirring device, including a feed port, a drying fan, a top cover, a stirring assembly, a stirring tank body, a rotating shaft, a driving motor and a bracket. The top of the stirring tank body is equipped with a top cover, the top cover is provided with a feed port, a drying fan is provided on one side of the feed port, the drying fan is fixed on the top outer wall of the top cover, the bottom of the stirring tank body is equipped with a bracket, the bracket is equipped with a driving motor, the output shaft of the driving motor is connected with a rotating shaft, the rotating shaft is provided inside the stirring tank body, and several groups of evenly distributed stirring assemblies are installed on the rotating shaft. By designing a scraping brush head, it can rotate with the rotating shaft during stirring, sweeping down particles adhered to the inner wall of the stirring tank, effectively preventing the masterbatch raw material from adhering to the inner wall of the tank body, avoiding the agglomeration phenomenon, so that the masterbatch raw material particles are stirred and dried more evenly and fully during stirring.

[0006] However, when the prior art CN207983753U is in use, since the dryer continuously inputs air into the mixing tank body, and the feed port is in a sealed state during the mixing process, the pressure of the mixing tank body will increase but moisture will be difficult to discharge. In addition, since the device in the prior art fails to preset the discharge port when discharging, the top cover needs to be opened when discharging. At the same time, after the top cover is opened, the setting of the mixing component also makes discharging difficult. Therefore, a material mixer is needed to solve the above problems.

During the mixing process, the drying fan body 7 is started to dry the masterbatch and the plastic raw material to remove moisture on the surface, and the moisture can be discharged through the connecting pipe 5.
