Description

Technical Field

[0001] The utility model relates to the technical field of toner processing, in particular to a stirring device for toner raw materials. Background Technique

[0002] Toner, also known as carbon powder, is a powdery substance used for imaging and fixing on paper in a laser printer. Black toner is composed of components such as binder resin, carbon black, charge control agent, and external additives. Color toner also needs to add pigments of other colors.

[0003] In response to different requirements, toner production is developing towards refinement, colorization, and high speed. The main methods for manufacturing toner are the grinding method and the polymerization method. When using the grinding method to prepare toner, usually treatment steps such as mixing, kneading and extrusion, grinding, and packaging are required;

[0004] When mixing toner raw materials, a stirring device is needed to fully mix various toner raw materials. However, most of the existing stirring devices only drive the stirring rod by a motor to stir and mix graphite powder. Therefore, when stirring toner raw materials, the raw materials accumulated at the bottom of the device are difficult to be evenly mixed with the upper-layer raw materials, thus affecting the evenness of the original stirring and mixing of toner. Therefore, a stirring device for toner raw materials is proposed to solve the above problems. Content of the Utility Model

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0027] As Figures 1-3 shown, a toner raw material mixing device proposed by the present utility model includes a support frame 1 and a mixing bin 4 located on the support frame 1. Two guide bins 3 are fixedly connected to the upper end of the support frame 1; a mixing member 5 for mixing raw materials is provided on the guide bin 3 and the mixing bin 4. The guide bins 3 located on both sides of the support frame 1, in cooperation with the mixing member 5, can re - convey the raw materials accumulated at the bottom in the mixing bin 4 back to the mixing bin 4 to improve the mixing uniformity of the toner raw materials.

[0028] In the present utility model, a receiving box 2 is placed inside the support frame 1. The receiving box 2 located inside the support frame 1 is used to receive the mixed raw materials. The upper end of the mixing bin 4 is communicated with a feeding hopper 6. The feeding hopper 6 located on the mixing bin 4 is used to input the toner raw materials to be mixed.

[0029] In an alternative embodiment, the mixing member 5 includes a double - shaft motor 51 fixedly connected to the upper end of the mixing bin 4. Output shafts at both ends of the double - shaft motor 51 are fixedly connected with driving rods 52. The bottom driving rod 52 penetrates and extends into the mixing bin 4. A stirring rod 57 is fixedly connected to the outside of the bottom driving rod 52. The inner bottom wall of the guide bin 3 is rotatably connected with a rotating shaft 54. A conveying paddle 55 is fixedly connected to the outside of the rotating shaft 54. A guide frame 58 is fixedly connected to the inner bottom wall of the mixing bin 4. A return pipe 56 is communicated between the mixing bin 4 and the guide bin 3. A guide pipe 510 is communicated between the mixing bin 4 and the guide bin 3 and is located below the return pipe 56. The lower end of the mixing bin 4 is communicated with a discharge pipe 59 that penetrates through the support frame 1 at one end.

[0030] In this embodiment, when the double - shaft motor 51 drives the upper and lower driving rods 52 to rotate, it can stir and mix the toner raw materials input into the mixing bin 4 through the rotating stirring rod 57. At the same time, it can also drive the rotating shaft 54 through the transmission member 53 to drive the conveying paddle 55 to rotate synchronously, so as to re - convey the accumulated toner raw materials to the upper part of the mixing bin 4 and stir and mix them with the raw materials above in the mixing bin 4 again to improve the mixing uniformity of the raw materials.

[0031] It should be noted that the lower end of the mixing bin 4 is conical, and the material guiding pipe 510 is inclined and connected between the conical end of the mixing bin 4 and the material guiding bin 3. The inclined material guiding pipe 510 can guide the toner raw material in the mixing bin 4 into the material guiding bin 3. The return pipe 56 is inclined and connected between the upper ends of the mixing bin 4 and the material guiding bin 3, and the inclined return pipe 56 can guide the raw material conveyed upward by the material guiding bin 3 into the mixing bin 4.

[0032] Among them, the upper end of the right rotating shaft 54 penetrates and extends to the outside of the right material guiding bin 3. A transmission member 53 for driving the rotating shaft 54 is provided on the rotating shaft 54 and the top driving rod 52. The transmission member 53 includes two groups of pulleys fixedly connected to the upper ends of the two rotating shafts 54 and the top driving rod 52 respectively. An activity belt is sleeved outside the pulley. The number of the activity belts is two, and the two activity belts are sleeved on the two groups of pulleys, that is, each group of pulleys corresponds to an activity belt. The top driving rod 52 is in a 'dry' shape, and the 'dry'-shaped top driving rod 52 can stably support the two pulleys thereon.

[0033] In an optional embodiment, the material guiding frame 58 is composed of two baffle blocks 581 and a material guiding block 582, forming a 'work' shape through the two baffle blocks 581 and the material guiding block 582. The two baffle blocks 581 are fixedly connected to the inner wall of the conical end of the mixing bin 4 and are located on the front and back sides of the feeding port of the material guiding pipe 510. The material guiding block 582 is trapezoidal. The 'work'-shaped material guiding frame 58 can block the falling toner raw material through the baffle blocks 581 and then guide it to the material guiding pipe 510 through the material guiding block 582.

[0034] In this embodiment, after the 'work' shape is formed by the baffle block 581 and the material guiding block 582, when the valve on the discharge pipe 59 is closed, the raw material can be guided into the material guiding pipe 510. Conversely, when the valve on the material guiding pipe 510 is closed, the raw material can be discharged through the discharge pipe 59 to improve the smoothness of the raw material guiding.

[0035] It should be noted that the number of the stirring rods 57 is several, and the several stirring rods 57 are annularly and equidistantly distributed on the bottom driving rod 52, and the lowermost stirring rod 57 is attached to the upper surface of the baffle block 581, so that when the stirring rods 57 stir and mix the raw material, they can also scrape the raw material on the baffle block 581 to reduce the amount of raw material attached to the baffle block 581 when the toner raw material is discharged.

[0036] The working principle of the above embodiment is as follows:

[0037] After the toner raw materials to be mixed are put into the feeding hopper 6, the double-shaft motor 51 can be started to drive the upper and lower driving rods 52 to rotate. The rotating bottom driving rod 52 can drive the stirring rod 57 to stir and mix the toner raw materials put into the mixing bin 4. At the same time, the rotating top driving rod 52 can also drive the rotating shaft 54 through the transmission member 53 to drive the conveying paddle 55 to rotate synchronously. After stirring for a period of time, the valve on the material guiding pipe 510 can be opened. At this time, the valve on the discharge pipe 59 is in a closed state. Therefore, the materials falling into the mixing bin 4 are stirred by the stirring rod 57 and guided by the material guiding frame 58 into the material guiding pipe 510, and then can be re-conveyed back to the raw materials from above the mixing bin 4 through the conveying paddle 55 and the return pipe 56, and are stirred and mixed again with the raw materials above the mixing bin 4 to improve the uniformity of raw material mixing. After the raw materials are stirred and mixed, the valve on the material guiding pipe 510 is closed, and the valve on the discharge pipe 59 is opened, so that the raw materials are guided by the material guiding frame 58 and discharged from the discharge pipe 59.

[0038] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
