Description

Technical Field

[0001] The utility model relates to the technical field of printer carbon powder, in particular to a material control mechanism for filling printer carbon powder. Background Art

[0002] A printer is one of the computer's output devices, used to print computer processing results on related media. The toner cartridge is an important component in the printer. Current printer consumables can be roughly divided into three categories: ribbons, inkjet and laser; and the material control mechanism for printer toner filling is a mechanism specially designed to control and manage the flow and distribution of powder during the printer toner filling process.

[0003] In the prior art, when filling printer toner, the toner flows downward. Due to the lack of a material control mechanism during the filling process, the toner's continued downward flow may clog the pipe, preventing the toner from entering the toner cartridge and preventing quantitative filling. Furthermore, when the pipe is clogged, workers need to manually clear the blockage, which is time-consuming and labor-intensive, increasing workers' labor intensity and inconvenience. In view of this, we have introduced a material control mechanism for printer toner filling. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-3 The utility model provides a technical solution: a material control mechanism for filling toner in a printer, comprising: a positioning cylinder 3, a cover plate 2 is connected to the top of the positioning cylinder 3, and a quantitative cylinder 8 is provided at the bottom of the positioning cylinder 3;

[0024] Pipeline 10, the pipeline 10 is connected between the metering cylinder 8 and the positioning cylinder 3, and a valve 9 is provided on the surface of the pipeline 10. The valve 9 is preferably a powder butterfly valve, such as a McQuay powder butterfly valve, which controls the flow and cutoff of the medium by rotating the valve plate, and has high flexibility and accuracy in regulating and controlling the powder flow;

[0025] The metering cylinder 8 is provided with a driving mechanism inside, and the cylinder 18 of the driving mechanism drives the piston block 11 to move inside the metering cylinder 8, so that the piston block 11 pushes the printer toner out of the metering cylinder 8 to form controlled filling.

[0026] The driving mechanism includes a push rod 19 provided at the output end of the cylinder 18 , the piston block 11 is slidably connected to the interior of the metering cylinder 8 , and the cylinder 18 is connected to one side of the piston block 11 .

[0027] A weight sensor 14 is embedded in the bottom of the metering cylinder 8 . The top of the weight sensor 14 is flush with the bottom wall and is used to detect the weight of the printer toner flowing out of the pipe 10 .

[0028] One side of the piston block 11 is connected to a limiting rod 12, and one end of the limiting rod 12 passes through the metering cylinder 8 and is connected to a limiting disk 13. By using the limiting rod 12 and the limiting disk 13 together, the movement of the piston block 11 can be limited, so that the piston block 11 is always in a horizontal state. The surface of the limiting rod 12 is provided with a spring 16, which facilitates buffering the movement of the piston block 11.

[0029] The top of the cover plate 2 is connected to a motor 1, the output end of the motor 1 is connected to a rotating rod 5, the surface of the rotating rod 5 is connected to stirring rods 6 at equal intervals, the stirring rods 6 and the rotating rod 5 are fixedly arranged, and one side of the stirring rod 6 is connected to a scraper 4, the scraper 4 can be set to scrape off the printer toner remaining on the inner wall of the positioning cylinder 3, and the scraper 4 and the stirring rod 6 are fixedly arranged.

[0030] A support rod 7 is connected between the metering cylinder 8 and the positioning cylinder 3. The support rod 7 can support the metering cylinder 8 and the positioning cylinder 3, and the upper and lower ends of the support rod 7 are welded to the metering cylinder 8 and the positioning cylinder 3 respectively.

[0031] The bottom of the rotating rod 5 is connected to a spiral rod 17, which extends to the inside of the pipe 10. The surface of the spiral rod 17 is connected to a spiral blade 15. The combined use of the spiral rod 17 and the spiral blade 15 can prevent the pipe 10 from being blocked and allow the printer toner to move downward from the inside of the positioning cylinder 3.

[0032] Specifically, when in use, the motor 1 is started, and the output end of the motor 1 is used to drive the rotating rod 5 and the stirring rod 6 to rotate, thereby stirring the printer toner inside the positioning cylinder 3, so that the printer toner is mixed and convenient for use. At the same time, under the continuous rotation of the stirring rod 6, one side of the stirring rod 6 will drive the scraper 4 to rotate, so that the scraper 4 is used to scrape off the printer toner remaining on the inner wall of the positioning cylinder 3, which is convenient for subsequent use.

[0033] By controlling the valve 9 to control the opening and closing of the pipeline 10, the motor 1 drives the rotating rod 5 to rotate continuously, which can drive the screw rod 17 and the spiral blade 15 to rotate. The combined use of the screw rod 17 and the spiral blade 15 can prevent the pipeline 10 from being blocked, allowing the printer toner to move downward from the inside of the positioning cylinder 3 and fall on the surface of the weight sensor 14, so that the weight of the printer toner can be detected. The weight sensor 14 controls the closing of the valve 9 to allow the mixed printer toner to enter the inside of the metering cylinder 8, thereby forming a quantitative weight. When the set weight is met, the controller of the mechanism controls the start cylinder 18, and the controller simultaneously controls the powder butterfly valve to close and stop feeding (it can also control the motor 1 to stop rotating at the same time), allowing the cylinder 18 to drive the push rod 19 to move. The movement of the push rod 19 can drive the piston block 11 to move inside the metering cylinder 8, thereby pushing out the quantitative printer toner inside the metering cylinder 8, so that the printer toner is quantitatively filled, which is more convenient to use.

[0034] When the piston block 11 is moving, the limiting rod 12 and the limiting plate 13 on one side of the piston block 11 work together to limit the movement of the piston block 11, so that the piston block 11 is always in a horizontal state, and the spring 16 on the surface of the limiting rod 12 will be stretched, thereby cushioning the movement of the piston block 11, making it easy to use.

[0035] When the piston block 11 pushes the printer toner in the metering cylinder 8 out, the controller of the mechanism controls the powder butterfly valve to reopen and discharge the powder, the motor 1 continues to rotate, and the cylinder 18 drives the piston block 11 to return to its position, preparing for the next quantitative addition in the metering cylinder 8.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
