Description

Technical Field

[0001] The invention belongs to the technical field of printer toner cartridges, and in particular relates to a recycling device for an environmentally friendly printer toner cartridge. Background Art

[0002] The toner cartridge is an important component in the operation of the printer. The toner cartridge in the printer drum provides raw materials for printing work. After the toner cartridge is used up, it is of great significance to recycle it. Most of the existing recycling methods are to directly recycle the materials after crushing the toner cartridge. Only a small number of toner cartridges can be directly recycled.

[0003] The traditional crushing method generally crushes the printer toner cartridge by squeezing and cutting with a crushing roller. After squeezing and cutting, the toner cartridge has more fragments pressed together due to the greater pressure. If there is still toner in the toner cartridge, the toner will be pressed in the middle and difficult to separate. As a result, the recycled toner cartridge fragments contain a large amount of toner, which not only causes dust pollution, but also causes the purity of the recycled toner to be not high enough. Summary of the invention

Due to the limitation of the arc groove, the separation barrel will swing up and down while rotating, causing the toner in the toner cartridge fragments to leak out under the impact, and the toner is thrown out of the filter hole under the action of centrifugal force, so as to achieve the effect of improving the purity of the recovered toner cartridge material.

The high-speed airflow passes through the gaps in the toner cartridge fragments and directly blows out the toner in the toner cartridge, thereby reducing the residual toner in the toner fragments, further improving the purity of the toner cartridge material recovery, and avoiding dust pollution.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. When the disc is set to rotate, the disc drives the separation barrel to rotate through the sliding column. The spring applies an upward elastic force to the separation barrel, so that the rotating wheel moves along the arc surface of the arc groove at the bottom of the limiting ring. Due to the limitation of the arc groove, the separation barrel swings up and down while rotating, so that the toner cartridge fragments move up and down inside the separation barrel and collide with the blocking rod, so that the toner in the toner cartridge fragments leaks out under the impact, and the toner is thrown out of the filter hole under the action of centrifugal force, so as to achieve the effect of improving the purity of the toner cartridge material recovery.

[0027] 2. The separation barrel moves up and down, and the pressure cylinder moves up and down with it. When the pressure cylinder moves downward, the valve cover on the top of the air vent will play a one-way ventilation role, blocking the air vent, allowing the gas inside the pressure cylinder to be compressed and pass through the one-way valve, and then be ejected from the air pipe at high speed. The high-speed airflow passes through the gaps in the toner cartridge fragments and directly blows out the toner in the toner cartridge, thereby reducing the residual amount of toner in the toner fragments, further improving the purity of the toner cartridge material recovery, and avoiding dust pollution.

[0028] 3. The fan set up will draw the air inside the dustproof cloth to the outside through the air duct, so that low pressure is formed inside the dustproof cloth to absorb the floating toner. The air inlet holes outside the air duct can make the air pressure inside the dustproof cloth more uniform, so as to prevent toner from floating and prevent dust pollution.

[0029] 4. After the set collection box rotates, the slider rotates along the slide slot, and the collection box can be easily taken out. The operator then stands on the anti-slip plate, holds the handle, and controls the electric push rod to retract through the control switch, so that the rotating wheel and the limit ring are no longer in contact, and the separation barrel can be easily lifted upward to achieve the effect of easy use and convenient operation.

[0046] In order to achieve the purpose of convenient use, the device is implemented by the following technical solutions: at least two evenly distributed sliders 39 are fixedly connected to the top of the outer wall of the collection box 11, and a slide groove 40 matched with the slider 39 is opened at the bottom of the inner wall of the outer cylinder 1. The slide groove 40 is an "inverted L-shaped groove. After the collection box 11 is rotated, the slider 39 rotates along the slide groove 40, so that the collection box 11 can be easily taken out. The outer wall of the outer cylinder 1 is fixedly connected to the anti-skid plate 37, and the outer wall of the anti-skid plate 37 is fixedly connected to the outer wall of the leg 2.

The air inlet 41 outside the air duct 9 can make the air pressure inside the dustproof cloth 10 more uniform, so as to prevent the toner from floating and prevent dust pollution. The toner on the outside of the dustproof cloth 10 will slide along the inclined surface of the dustproof cloth 10 to the inside of the collecting box 11 and be collected. When the classification is completed, the collecting box 11 is rotated to make the slider 39 rotate along the slide groove 40, and the collecting box 11 can be easily taken out. The operator then stands on the anti-slide plate 37, holds the handle 5, and controls the electric push rod 30 to be retracted through the control switch 34, so that the rotating wheel 31 is no longer in contact with the limiting ring 6, and the separation barrel 3 can be easily lifted up, and the toner cartridge fragments that have been cleaned inside the separation barrel 3 can be dumped out, so as to achieve the effect of easy use and convenient operation.
