Abstract
Description
Technical Field
[0001] This utility model relates to plastic production equipment, specifically to a plastic color matching 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. Patent document CN 219153401 U discloses a color powder device for a plastic color mixing machine, which has a color powder cavity. Below the color powder cavity are rotating blades and a powder dispensing gear, with the powder dispensing gear and rotating blades partially stacked. The rotating blades push the color powder to the chamfered powder dispensing groove where the gear is located. The gear uses its tooth grooves to drive the color powder, causing it to be output from the powder outlet and fall into the plastic color powder mixing and stirring device of the color mixing machine. The powder outlet and the color powder cavity are located on opposite radial sides of the gear, thus allowing the plastic to enter directly from above the mixing and stirring device, while the color powder enters from the side of the mixing and stirring device. Utility Model Content
[0004] The technical problem solved by this utility model is: how to improve the color powder supply device so that the color powder in the color powder cavity can be fully stirred, fully dispersed, and smoothly fed.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a color powder supply device for a plastic color mixing machine, including a color powder container and a color powder transverse conveying mechanism disposed below the color powder container. The color powder transverse conveying mechanism includes a conveying housing, a rotating blade, and a powder feeding gear. The conveying housing has a neck cavity connected to the color powder container, a gear cavity communicating with the neck cavity, and a powder outlet communicating with the gear cavity. The neck cavity and the gear cavity partially overlap. The rotating blade is located in the neck cavity, and the powder feeding gear is located in the gear cavity. The rotating blade is located above the powder feeding gear. A stirring blade is coaxially disposed on the rotating blade, and the stirring blade extends upward into the color powder container.
[0006] According to the above technical solution, under the action of gravity, the pigment powder falls into the neck cavity after passing through the stirring blades. The stirring blades stir and disperse the pigment powder, and the rotating blades scrape the pigment powder into the gear cavity along the bottom surface of the neck cavity. The pigment powder enters the space formed by the tooth groove of the powder feeding gear and the side wall of the gear cavity. The rotating powder feeding gear conveys the pigment powder to the powder outlet, which is set downwards. The pigment powder falls into the mixing and stirring device of the pigment machine through the powder outlet.
[0007] The stirring blade comprises several individual blades, each with a bending structure. The stirring blade includes blades with upward bending structures and blades with downward bending structures. The upward bending angles and lengths of the upward bending structures differ among the blades with upward bending structures. This expands the stirring range of the stirring blade, facilitating thorough mixing and dispersion of the pigment powder.
[0008] A gear set is installed inside the conveying housing, positioned below the powder-feeding gear. The driving gear in the gear set is coaxial with the rotating blades and driven by a motor mounted on the conveying housing. The driven gear in the gear set is coaxial with the powder-feeding gear. Simultaneously, the motor drives the driving gear, which in turn drives the rotating blades and the stirring blades to rotate synchronously. The driving gear drives the driven gear through an intermediate gear, and the driven gear rotates coaxially with the powder-feeding gear.
[0009] The conveying housing includes a top cover plate, a gear cavity plate, a gear set upper cover plate, and a gear set lower base arranged sequentially from top to bottom. The neck cavity is located on the top cover plate, the gear cavity and the powder outlet are located on the gear cavity plate, the gear set is located between the gear set upper cover plate and the gear set lower base, and the motor is installed at the bottom of the gear set lower base.
[0010] Compared with the prior art, the present invention has the following technical effects: the stirring blade and the rotating blade are coaxially arranged, which simplifies the structure, improves the stirring effect, and ensures smooth powder feeding; the individual blades of the stirring blade have different shapes, resulting in a wide stirring range, which is conducive to the full stirring and dispersing of the color powder.

[0024] Combination Figure 3 , Figure 4 The color powder supply device of the plastic color mixing machine includes a color powder container 10 and a color powder transverse conveying mechanism 20 disposed below the color powder container. The color powder transverse conveying mechanism includes a conveying housing 30, a rotating blade 21, and a powder feeding gear. The conveying housing has a neck cavity 311 connected to the color powder container, a gear cavity 331 communicating with the neck cavity, and a powder outlet 332 communicating with the gear cavity. The neck cavity and the gear cavity partially overlap. The rotating blade is located in the neck cavity, and the powder feeding gear is located in the gear cavity. The rotating blade is located above the powder feeding gear. A stirring blade 23 is coaxially disposed on the rotating blade and extends upward into the color powder container.
[0025] like Figure 3 The stirring blade 23 comprises several blade units 230, each blade unit having a bending structure. The stirring blade includes blade units with an upward bending structure 231 and blade units with a downward bending structure 232. There are two blade units with the upward bending structure 231, and the upward bending structure of each blade unit has a different bending angle.

The driving gear in the gear set is coaxially arranged with the rotating blade 21 and driven by a motor 24, which is mounted on the conveying housing. The driven gear in the gear set is coaxially arranged with the powder-feeding gear. The shafts connected to the motor 24 include an upper shaft and a lower shaft. The stirring blade 23 and the rotating blade 21 are mounted on the upper shaft 361, and the driving gear 365 is mounted on the lower shaft 362. A coupling 364 is fitted at the connection between the upper and lower shafts. A magnet 363 is provided at the end of the lower shaft to attract the upper shaft, thus facilitating the separation and connection of the upper and lower shafts. Figure 7 , Figure 8 As shown.
[0027] like Figures 4 to 5 The conveying housing 30 includes a top cover plate 31, a gear cavity plate 33, a gear set upper cover plate 34, and a gear set lower base 35 arranged sequentially from top to bottom. The neck cavity 311 is disposed on the top cover plate. The gear cavity 331 and the powder outlet 332 are disposed on the gear cavity plate.

[0028] In actual production, the color powder container 10 is inserted into the neck cavity 311. Under the action of gravity, the color powder in the container falls into the neck cavity 311 after passing through the stirring blade 23. Simultaneously, the motor 24 drives the drive gear, which in turn drives the rotating blade 21 and the stirring blade 23 to rotate synchronously. The drive gear drives the driven gear through the intermediate gear, and the driven gear rotates coaxially with the powder feeding gear. The stirring blade 23 stirs and disperses the color powder, while the rotating blade 21 scrapes the color powder into the gear cavity 331 along the bottom surface of the neck cavity 311. The color powder enters the space formed by the tooth groove of the powder feeding gear and the side wall of the gear cavity, and the rotating powder feeding gear conveys the color powder to the powder outlet 332. The powder outlet is downward-facing, and the color powder falls through the powder outlet 332 into the mixing and stirring device of the color powder machine.
