Description

Technical Field

[0001] The utility model belongs to the technical field of plastic production equipment, and in particular relates to a toner device used in a plastic color matching machine. Background Art

[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 toner device for a plastic color matching machine which occupies a small space, has stable material discharge and can effectively control the toner delivery amount.

[0005] The technical solution adopted by the utility model is:

[0006] A toner device for a plastic color matching machine comprises a toner base, a toner containing groove is provided on the toner base, a pushing impeller is rotatably connected in the toner containing groove, a powder outlet channel connected to the color matching machine is provided at the bottom of the toner containing groove, the powder outlet channel can be connected to the color matching chamber of the color matching machine, a powder outlet shaft rotating around a horizontal axis is provided in the powder outlet channel, and a plurality of powder outlet grooves are provided on the circumferential surface of the powder outlet shaft.

[0007] Furthermore, a pushing shaft for driving the pushing impeller to rotate is provided on the toner base, and the pushing shaft is connected to a motor arranged at the rear side of the toner base through a transmission mechanism.

[0008] Furthermore, the transmission mechanism includes a driving gear installed on the first output shaft of the motor and a driven gear installed on the lower end of the pusher shaft, and the driving gear is meshed and connected with the driven gear.

[0009] Furthermore, a cover plate is connected below the toner base, a through hole is opened on one side of the cover plate to form a powder outlet channel between the cover plate and the toner base, and the other side of the cover plate is covered outside the transmission mechanism.

[0010] Furthermore, a wall surface of the through hole is arranged to be inclined downward toward the color matching cavity of the color matching machine. The toner in the powder outlet slot can enter the color matching cavity along the wall surface.

[0011] Furthermore, the powder output shaft is sleeved on the second output shaft of the motor. The utility model can control the toner delivery amount by the rotation angle of the motor.

[0012] Furthermore, a blocking column is arranged on the wall surface of the toner containing groove, and a first notch is formed at a position of the pushing impeller corresponding to the blocking column. The blocking column can pass through the notch to break up the condensed toner, thereby preventing the toner from agglomerating.

[0013] Furthermore, the toner containing groove is connected to a toner container, and a second notch is provided on the toner container at a position corresponding to the stop column. The second notch cooperates with the stop column to position and install the toner container, thereby preventing the toner container from falling off due to vibration during operation.
