Description

TECHNICAL FIELD

[0001] The utility model relates to plastic production equipment, concretely relates to plastic toner machine. BACKGROUND

[0002] Plastic products, such as tableware, tables and chairs, vehicle supplies, toys, etc. The coloring of plastics adopts a direct spraying method, which is relatively simple, but the coloring effect is not good, and it is easy to discolor. Therefore, the existing coloring of plastics has directly mixed toner with plastic raw materials, and directly injection molding, without discoloration phenomenon.

[0003] The plastic color matching machine is used for mixing and stirring plastic and toner, and includes a plastic supply device, a toner supply device, and a device for mixing and stirring plastic and toner. For example, the patent document with the authorization announcement number CN218019493U discloses an automatic stirring color matching machine for plastic particles, a colorant device is connected to the machine shell, a powder outlet groove is arranged in the bottom of the powder storage box body of the colorant device, the powder outlet groove is rotatably connected with a feeding gear located partially in the stirring cavity, a feeding cavity is formed between the teeth of the feeding gear and the side wall of the powder outlet groove, and the feeding gear is driven to rotate by a power device. The feeding gear rotates, and the colorant received on one side of the feeding gear is transported to the other side of the feeding gear, which is connected to the stirring cavity. In this way, the feeding gear can transport the colorant from the powder storage box body to the stirring cavity on the side. SUMMARY

[0004] The technical problem solved by the utility model is that the colorant may be compressed in the tooth groove of the feeding gear on one side of the stirring cavity and cannot fall into the stirring cavity under the action of gravity.

[0005] To solve the above technical problems, the utility model provides the following technical scheme: the discharging structure of the toner supply device includes a powder outlet groove communicating with the stirring cavity, a feeding gear arranged in the powder outlet groove, a powder outlet on one side of the powder outlet groove, the powder outlet being arranged vertically and above the stirring cavity, a powder stirring member arranged at the powder outlet, a first bending structure arranged at the front end of the powder stirring member, a second bending structure arranged at the tail end of the powder stirring member, the first bending structure being capable of penetrating into the tooth groove of the feeding gear, the annular structure of the second bending structure being pivotally connected to a vertical column, the sheet structure of the second bending structure abutting against the side wall of the vertical column groove, the vertical column being arranged in the vertical column groove, and the vertical column groove being arranged beside the discharging opening.

[0006] When the feeding gear rotates, the first bending structure of the powder poking member enters the tooth groove of the feeding gear one by one, so that the toner in the tooth groove falls into the powder outlet.

[0007] The powder outlet groove is arranged on the powder outlet groove plate, and the powder outlet groove plate is provided with a powder poking groove and a column groove with the same depth as the powder outlet groove.

[0008] The column groove is shaped according to the second bending structure, and the second bending structure is sunk in the column groove.

[0009] The angle between the sheet structure of the second bending structure and the main body of the powder poking member is an acute angle, and the side wall of the column groove abutting against the sheet structure is inclined, and the inclination direction is the same as that of the sheet structure. When the feeding gear rotates, the teeth of the feeding gear act on the first bending structure, so that the powder poking member is elastically deformed, and at the same time, the powder poking member rotates reversely around the column (different from the forward rotation when the first bending structure enters the tooth groove), and the first bending structure leaves the tooth groove. At this time, the sheet structure is elastically deformed on the inclined side wall of the column groove. Since the inclination direction of the inclined side wall of the column groove is the same as that of the sheet structure, the elastically deformed sheet structure is in large-area contact with the inclined side wall of the column groove, and is stable. When the first bending structure is aligned with the next tooth groove, the first bending structure enters the tooth groove, and the sheet structure returns to the original state.

[0010] The first bending structure comprises a first bending portion and a second bending portion, the angle of the first bending portion is obtuse, the second bending portion is in the shape of a circular arc, and the first bending portion enables the second bending portion to be deeply inserted into the tooth groove of the feeding gear.

[0011] The powder outlet is matched with a falling powder guide sleeve, and the falling powder guide sleeve extends downward into the stirring cavity.

[0012] One end of the powder poking member is pivotally connected to the column and abuts against the side wall of the column groove, has good elasticity, is beneficial to the toner to be separated from the tooth groove, and has a long service life. BRIEF DESCRIPTION OF DRAWINGS

[0025] Combination Figure 1 , Figure 2 The feeding structure of the color powder supply device includes a powder outlet 10 connected to the mixing chamber and a feeding gear 20 disposed in the powder outlet 10. A powder outlet 30 is provided on one side of the powder outlet 10. The powder outlet is vertically disposed and located above the mixing chamber. A powder-dispensing component 40 is provided at the powder outlet. The front end of the powder-dispensing component is provided with a first bending structure 41, and the tail end of the powder-dispensing component is provided with a second bending structure 42. The first bending structure can penetrate into the tooth groove of the feeding gear. The annular structure 421 of the second bending structure is pivotally connected to the column 51. The sheet-like structure 422 of the second bending structure abuts against the side wall of the column groove 50. The column is located in the column groove, and the column groove is located beside the discharge port.

[0026] The powder outlet 10 is formed on the powder outlet plate 11. The powder outlet plate has a powder-dispensing groove 12 and a column groove 50 with the same depth as the powder outlet. The powder-dispensing groove and the column groove are connected to the powder outlet. The powder outlet 30 is formed on the powder outlet plate and located below the powder-dispensing groove.

[0027] The shape of the column groove 50 is modeled after the second bending structure 42, which is embedded in the column groove 50.

[0028] The angle between the sheet structure 422 of the second bending structure and the main body of the powder stirring member 40 is an acute angle, and the side wall of the columnar groove abutting against the sheet structure 422 is inclined, and the inclination direction is the same as the inclination direction of the sheet structure.

[0029] The first bending structure 41 comprises a first bending portion 411 and a second bending portion 412, the angle of the first bending portion is obtuse, and the second bending portion is in a circular arc shape, and the first bending portion enables the second bending portion to be deeply inserted into the tooth groove of the feeding gear 20.

[0030] As shown in Figure 3 , the powder outlet 30 is matched with a powder falling guide sleeve 31, and the powder falling guide sleeve extends downward into the stirring cavity.

[0031] Referring to Figure 1 , the toner in the toner container falls into the neck cavity 60, and the rotating blade 61 at the bottom of the neck cavity scrapes the toner into the powder outlet groove 10. The toner enters the space formed by the tooth groove of the feeding gear 20 and the side wall of the powder outlet groove 10, and the rotating feeding gear 20 conveys the toner to the powder outlet 30. The first bending structure 41 of the powder stirring member enters the tooth groove of the feeding gear 20 one by one, so that the toner in the tooth groove falls into the powder outlet 30 from the feeding gear. Among them, since the sheet structure 422 abuts against the side wall of the columnar groove 50, the front end of the powder stirring member 40 has a tendency to rotate towards the feeding gear 20, and this tendency is the power source for the first bending structure 41 to enter the tooth groove of the feeding gear 20. The feeding gear 20 rotates, and the teeth of the feeding gear act on the first bending structure 41, so that the powder stirring member 40 and the sheet structure 422 of the second bending structure are elastically deformed, and when the first bending structure 41 is aligned with the next tooth groove, the first bending structure enters the tooth groove. The powder outlet 30 is downwardly arranged, and the toner falls into the stirring cavity of the toner machine through the powder outlet.

[0032] The above is only a preferred embodiment of the present application, and for those skilled in the art, according to the idea of the present application, the specific embodiment and application range can be changed, and the content of the specification should not be understood as a limitation of the present application.
