Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of carbon powder recycling, in particular to a residual powder recycling and cleaning device based on a carbon powder cartridge. BACKGROUND

[0002] A carbon powder cartridge is a storage and delivery device for solid powdery substances, mainly responsible for storing carbon powder and delivering it to a selenium drum, which is a supplier of printing media and has an important influence on printing quality. Laser printers convert images into visible images through photosensitive materials on the selenium drum, and the carbon powder in the carbon powder cartridge is an important component of these images. Multifunctional copiers rely on carbon powder in the carbon powder cartridge to form the final printing result.

[0003] After the carbon powder cartridge is used up, it is usually replaced, and the replaced carbon powder cartridge can be recycled. The carbon powder in the carbon powder cartridge is a valuable resource, and recycling residual powder can achieve resource reuse and reduce the demand for new carbon powder.

[0004] A residual powder recycling and cleaning device based on a carbon powder cartridge is disclosed in Chinese patent CN2022106344549, which includes a collection barrel, a top cover, a connecting pipe, a sticky block, and a fan. The top cover is detachably connected to the upper part of the collection barrel, and the connecting pipe is connected to the top cover. One end of the connecting pipe penetrates into the collection barrel, and the other end of the connecting pipe is connected to two sticky blocks. The end of the connecting pipe inside the collection barrel is connected to the fan. The convex block rotates to continuously move the lifting frame up and down, thereby vibrating the carbon powder cartridge, shaking off the residual powder adhering to the inner wall of the carbon powder cartridge, reducing residue, and improving recycling effect. The fan operates to suck the residual powder in the carbon powder cartridge into the collection barrel through the connecting pipe. In the above-mentioned patent, the residual powder adhering to the inner wall is shaken off by vibrating the carbon powder cartridge, reducing residual powder. However, the residual powder adheres to the inner wall of the carbon powder cartridge again after being shaken off, and the residual powder cannot be fully and quickly recycled and cleaned. SUMMARY

[0005] In order to overcome the difficulty of fully and quickly recycling residual powder by relying on the vibration of the carbon powder cartridge, the technical problem to be solved is to provide a residual powder recycling and cleaning device based on a carbon powder cartridge that can fully and quickly recycle residual powder.

[0006] The technical solution is: a residual powder recovery and cleaning device based on a toner cartridge, comprising a mounting seat, a support plate, a mounting rod, a mounting shell, a wind separation assembly, a dust suction pipe and an air outlet pipe.

[0009] Furthermore, it also includes a connecting block, a telescopic rod, a second spring, an arc rod and a connecting rod. The outer side of the lower part of the dust suction pipe is symmetrically connected to two groups of connecting blocks in a front-to-rear rotation. The number of connecting blocks in each group is two, and the two connecting blocks are symmetrically arranged up and down. A telescopic rod is connected between the upper and lower connecting blocks, and a second spring is sleeved on the outer side of the telescopic rod. The two ends of the second spring are respectively connected to the fixed end and the movable end of the telescopic rod. The lower part of the dust suction pipe and the air outlet pipe is located between the upper and lower connecting blocks and is set as a bellows structure to facilitate the bending of the dust suction pipe and the lower part of the air outlet pipe. The outer side of the lower part of the dust suction pipe is connected to an arc rod, which is located between the upper and lower connecting blocks. The ends of the arc rod are rotatably connected to the adjacent connecting blocks with connecting rods.

[0010] Furthermore, it also includes a sleeve, a sleeve, a first spring, a ring and a pull rope. The left side of the support plate is connected to the sleeve, the middle part of the sleeve is slidably connected to the sleeve, the sleeve is sleeved on the outside of the dust suction tube, the lower part of the sleeve is connected to the sleeve, the middle part of the dust suction tube is slidably sleeved with a ring, the sleeve can be squeezed and matched with the ring, the front and back sides of the ring are connected to the pull rope, the pull rope passes through the upper connecting block and is connected to the lower connecting block.

[0011] Furthermore, it also includes a bidirectional screw, a sliding seat, a clamping block and a movable column. The middle part of the mounting seat is rotatably connected to the bidirectional screw, and the left and right sides of the top of the mounting seat are slidably connected to the sliding seat.

[0014] The beneficial effects are as follows: 1. The present invention extends the dust suction pipe and the air outlet pipe into the powder feeding hole of the carbon powder box, and the fan rotates to generate airflow, so that the airflow is discharged from the air outlet pipe, thereby blowing up the residual powder in the carbon powder box. At the same time, the airflow drives the residual powder into the dust suction pipe, and then the residual powder enters the installation shell and is blocked by the filter. The centrifugal separator can settle the residual powder in the installation shell in the collection barrel for collection.

[0015] 2. When the air flow flows through the air outlet duct, it can drive the turbine to rotate, thereby driving the turntable to rotate, and then driving the air nozzle to rotate. That is, the air nozzle blows out air while rotating, so that the residual powder adsorbed on the inner wall of the toner cartridge can be fully blown off and recovered, reducing the residual powder residue.

[0016] 3. Through the cooperation of the sleeve and the ring, the lower ends of the dust suction pipe and the air outlet pipe are bent to the left after entering the powder adding hole, ensuring that the air nozzle can be directed towards the inside of the toner cartridge, so that the residual powder adsorbed on the inner wall of the toner cartridge can be fully blown off, reducing the residual powder residue.
