Description

Technical Field

[0001] This utility model relates to plastic production equipment, specifically to a plastic color powder machine. Background Technology

[0002] Plastic products, such as tableware, tables and chairs, vehicle accessories, and toys, are often colored using direct spraying. While this method is simple, the coloring effect is poor and the color is prone to fading. Therefore, current plastic coloring methods involve directly mixing color powder with the plastic raw material and then injection molding it, which avoids color fading.

[0003] A plastic color mixing machine is used for mixing and stirring plastic and color powder. It includes a plastic supply device, a color powder supply device, and a device for mixing and stirring the plastic and color powder. For example, patent document CN218019493U discloses an automatic mixing and color mixing machine for plastic granules. A color material device is connected to the machine housing. The bottom of the powder storage box of the color material device has a powder outlet trough with one side communicating with a stirring chamber. A feeding gear, partially located within the stirring chamber, is rotatably connected to the powder outlet trough. The teeth of the feeding gear and the side wall of the powder outlet trough form a feeding cavity. When the feeding gear rotates, it transports the color material received on one side of the feeding gear to the other side, which is connected to the stirring chamber. Thus, the feeding gear can transport the color material from the powder storage box to the adjacent stirring chamber. The powder outlet, which is connected to the powder outlet trough, is set vertically. The feeding gear extends into the mixing chamber. The entire color powder supply device is attached to the outer wall of the mixing and stirring device. If the powder outlet and the outer wall of the mixing and stirring device are not sealed tightly, the color powder may leak out through the gap between the color powder supply device and the outer wall of the mixing and stirring device. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an assembly structure of a color powder supply device and a mixing and stirring device, wherein the color powder supply device includes a color powder container and a color powder base, the color powder container is installed on the color powder base, the color powder base is installed on the mixing and stirring device, the powder outlet of the color powder base is connected to the stirring chamber of the mixing and stirring device, an L-shaped structure is provided on the side of the color powder base connected to the mixing and stirring device, the top two sides of the mixing and stirring device are right-angled structures, the powder outlet is vertically set on the top of the L-shaped structure, the top of the right-angled structure is provided with a powder drop outlet, and the powder drop outlet is connected to the stirring chamber; the L-shaped structure and the right-angled structure cooperate, and the powder outlet and the powder drop outlet are vertically connected.

[0006] The pigment in the pigment container is conveyed to the powder outlet by a conveying mechanism in the pigment base, and then falls into the powder discharge port and enters the mixing chamber. The pigment enters the mixing chamber vertically, which effectively avoids pigment leakage compared to the horizontal entry of pigment into the mixing chamber in the prior art.

[0007] The number of color powder supply devices is one, installed on the left or right side of the mixing and stirring device, or the number of color powder supply devices is two, symmetrically installed on both sides of the mixing and stirring device.

[0008] A powder guide sleeve is fitted into the powder outlet, protruding downwards from the powder outlet and engaging with it. This facilitates accurate alignment between the powder outlet and the powder inlet, and also ensures accurate engagement between the powder base and the mixing and stirring device.

[0009] The bottom of the color powder base is provided with a connecting strip, and the outer wall of the mixing and stirring device is provided with a positioning strip. The positioning strip cooperates with the connecting strip and is connected by a connector.

[0010] The mixing chamber is fitted with a detachable container, and the top two sides of the detachable container are provided with first through holes corresponding to the powder discharge port.

[0011] The assembly structure of this utility model not only facilitates the assembly of the color powder supply device and the mixing and stirring device, but also ensures that the powder outlet and the powder discharge outlet can be accurately aligned, preventing the color powder from leaking out.
