[0002] Plastic products are indispensable products in people's lives, such as tableware, tables and chairs, vehicle supplies, toys, etc. Traditionally, plastic coloring is done by direct spraying, which is relatively simple, but the coloring effect is not good enough and it is easy to fade. Therefore, the existing plastic coloring has a method of directly mixing the color powder with the plastic raw material and directly forming the main color, which makes the coloring effect excellent and will not fade.

[0003] The Chinese patent application CN218196195U discloses a colorant device for a plastic color matching machine, comprising a color matching machine housing (1) having a stirring chamber (2), a colorant housing being provided on the color matching machine housing (1), a colorant chamber being provided on the colorant housing, a powder outlet channel being provided at the bottom of the toner chamber and communicating with the stirring chamber (2), a powder outlet gear (3) being rotatably connected to the powder outlet channel and partially located in the stirring chamber (2), a feeding space (4) being formed between the teeth of the powder outlet gear (3) and the wall of the powder outlet channel, and the powder outlet gear (3) being driven to rotate by a power assembly, and a pushing assembly capable of pushing the colorant to the powder outlet channel being provided at the bottom of the toner chamber. The toner is easy to agglomerate, thereby affecting the dosage of the toner. Moreover, the conveying amount of the toner is different, so it is necessary to equip powder outlet gears of different dosages, which has many accessories and high cost. At the same time, the driving mechanism of the colorant device is relatively complex and occupies a large space, and it is necessary to set a special colorant base on the side of the color matching machine to support the colorant device. Summary of the invention

[0004] In order to solve the above problems existing in the prior art, the utility model provides a roller assembly of a powder discharging device which occupies a small space, has stable material discharging and can effectively control the toner conveying amount.

[0026] See also Figure 1-6The present embodiment provides a roller assembly of a powder discharge device, which can be rotatably installed around a horizontal axis in a powder discharge channel of the powder discharge device, including a roller 1 with a plurality of powder discharge grooves 7 on the circumferential surface, and each powder discharge groove 7 is provided with a push block 2 that can push the toner out of the powder discharge groove 7, the push block 2 is installed in the powder discharge groove 7 through a rotating shaft 4, and push block guide rails 5 are provided at both ends of the rotating shaft 4. When the push block 2 rotates, it can move along a track 51 on the push block guide rail 5 in the radial direction of the roller 1 to push out the toner, and the push block guide rail 5 is fixed in the roller 1, and a central shaft 3 is passed through the center of the push block guide rail 5, and the central shaft 3 is fixed in the powder discharge channel.

[0027] The push block 2 and the roller 1 described in this embodiment can be installed in the powder outlet channel so as to rotate around the central axis 3. Specifically, the push block guide rail 5 is positioned and installed at both ends of the rotating shaft 4 by the mounting block 6, and the mounting block 6 can be mounted on the central axis 3 so as to rotate around the central axis 3. The mounting block 6 is arranged on both sides of the roller 1 and is fixedly connected to the roller 1, so that the roller 1 can be driven to rotate when the mounting block 6 rotates. The mounting block 6 is connected to an external power mechanism that drives it to rotate. The mounting block 6 is provided with a socket 61 connected to the external power mechanism. The external power mechanism can be a structure in which a motor drives a gear transmission, and of course it can also be directly driven by a motor.

[0028] In this embodiment, a flat surface is provided on the central shaft 3, and is positioned and connected to the push block guide rail 5 through the flat surface, so that the central shaft 3 and the push block guide rail 5 are fixed and cannot rotate, so that the push block 2 can move radially in the powder outlet groove 7 under the action of the trajectory 51 during the rotation process.

[0029] The distance between the track 51 on the push block guide rail 5 and the edge of the push block guide rail 5 is gradually reduced from top to bottom, thereby ensuring that the push block 2 in the powder outlet groove 7 can completely push out the toner in the powder outlet groove 7 when the drum 1 rotates downward.

[0030] When the external power mechanism of the utility model is started, the mounting block 6 rotates, driving the roller 1 and the push block 2 to rotate. While the push block 2 rotates, it moves radially along the track 51 set on the push block guide rail 5 along the roller 1, thereby pushing the toner out of the powder outlet groove 7, preventing the toner from agglomerating in the powder outlet groove 7, and ensuring the stability of the powder output.

[0031] The push block 2 of the utility model automatically pushes the colorant out of the powder outlet slot 7, has a self-cleaning function, and avoids the defect of unstable powder output caused by the toner sticking to the powder outlet slot 7. At the same time, it occupies a small space, has stable material output, and can effectively control the toner delivery amount.
