Description

Technical Field

[0001] The present invention relates to the technical field of printer devices, and particularly to a cleaning device suitable for manual powder filling. Background Art

[0002] Existing printing devices, especially some color printers, use paraffin powder or toner of various colors for spraying. These powders are packed in powder cans, and the powders are filled into the powder cans through existing devices. Many of them use manual methods for powder filling operations. In order to maintain the cleanliness of the working environment, a suction dust removal device is used. For example, a Chinese patent with the application number 201410576684.X discloses a drum assembly workbench with dust removal, including a tabletop and support feet. The tabletop is rectangular, a conveyor belt is provided in the middle of the tabletop, and the two sides of the tabletop are assembly areas. The assembly areas are divided into several adjacent assembly partitions by setting partitions. Except for the first and last ends, a deflector is suspended above the conveyor belt near the upstream section corresponding to the assembly partitions in the middle area. The deflector is V-shaped, the opening direction of the V-shaped deflector is opposite to the advancing direction of the conveyor belt, and the end of the deflector extends above the tabletop and is fixed to the tabletop. A receiving groove is provided at the part below the deflector in the assembly partition; filter holes are provided on the tabletop of the assembly partition at the end of the conveyor belt, and a dust removal chamber is provided below the tabletop of the assembly partition at the end of the conveyor belt. This kind of workbench can also be used during powder filling. Because during the powder filling process, when manually using chopsticks to constantly poke the powder into the powder can, a lot of powder will be splashed, which will cause pollution to the working environment and the human body. Therefore, cleaning is carried out through the suction structure on the front side, etc. However, this structure will also suck away some useful powder, resulting in some waste.

A support frame is installed on the bottom plate, and a first limit ring for limiting the insertion of the powder supply tank is fixed on the support frame. Above the first limit ring, a second limit ring is connected to the support frame and is used for the bottom of a funnel to be inserted downward and suspended. A suction duct is also installed and connected to the support frame and is located in front of the second limit ring and has an opening facing the rear.

[0005] As a preference for the present invention, the funnel is placed in the second limit ring.

[0006] As a preference for the present invention, a spring is connected between the funnel and the second limit ring.

[0007] As a preference for the present invention, the second limit ring is liftable.

[0008] Preferably, a third limiting ring for inserting and limiting the powder filling chopsticks is further installed on the support frame above the second limiting ring.

[0009] Preferably, the inner diameter of the third limiting ring is the same as the size of the discharge port at the bottom of the funnel.

[0010] Preferably, the powder filling chopsticks are inserted through the third limiting ring, and an Oxford belt in a circumferential array is connected between the side part of the powder filling chopsticks and the third limiting ring.

[0011] Preferably, the air extraction duct is connected to the support frame through a moving device.

[0012] Preferably, a recovery duct with an upward opening is arranged between the second limiting ring and the air extraction duct.

[0013] Preferably, a filter screen is connected to the opening of the recovery duct.

[0014] The beneficial effects of the present invention: The manual operation has higher precision, reduces powder splashing, and has better cleaning effect. Description of the Drawings

[0015] Figure 1 It is a three-dimensional structural schematic diagram of the embodiment. Detailed Embodiment

[0016] The following specific embodiments are only explanations of the present invention, and they do not limit the present invention. Those skilled in the art can make modifications without creative contributions to this embodiment according to needs after reading this specification, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.

[0017] Embodiment, as Figure 1 shown, a cleaning device suitable for manual powder filling includes a bottom plate 1 for supporting a powder supply tank. A support frame 2 is installed on the bottom plate 1. A first limiting ring 3 for sleeving and limiting the powder supply tank is fixed on the support frame 2. Above the first limiting ring 3, a second limiting ring 4 is connected to the support frame 2 and is used for the bottom of the funnel to be inserted downward and hung. An air extraction duct 5 is also installed and connected to the support frame 2 in front of the second limiting ring 4 and with an opening facing backward. After the powder tank is placed in the first limiting ring 3, the bottom of the funnel is aligned downward with the opening of the powder tank. The first limiting ring 3 is mainly to make the funnel move within a small range as much as possible, facilitate powder falling and reduce powder splashing, so that the wind force of the cleaning air extraction duct 5 can be smaller.

[0018] Preferably, the funnel 6 is placed in the second limiting ring 4. A spring 40 is connected between the funnel 6 and the second limiting ring 4. On the one hand, the spring 40 facilitates the placement of the powder tank into the first limiting ring 3 after the funnel 6 is lifted. On the other hand, during powder filling, an elastic vibration can be formed, making it easier for the powder to fall.

[0019] The second limiting ring 4 is liftable. This can be achieved through existing structures such as lifting air cylinders or lead screws.

[0020] Furthermore, a third limiting ring 7 for inserting and limiting the powder filling chopsticks is installed on the support frame 2 above the second limiting ring 4. Since the most important thing in manual powder filling is to continuously poke up and down with chopsticks, but if the operation range is too large, it is easy to splash the powder out. Therefore, the third limiting ring 7 can better limit the chopsticks to perform poking operations within a more effective area. Further, the inner diameter of the third limiting ring 7 is the same as the size of the discharge port at the bottom of the funnel 6. The powder filling chopsticks 8 are inserted through the third limiting ring 7, and an Oxford belt 70 arranged in a circumferential array is connected between the side of the powder filling chopsticks 8 and the third limiting ring 7, further improving the accuracy of poking.

[0021] The exhaust duct 5 is connected to the support frame 2 through a moving device, facilitating the adjustment of the exhaust duct 5 and making it more flexible and effective to use. The moving device can also adopt existing related moving equipment such as pneumatic cylinders and lead screws.

[0022] Furthermore, a recovery duct 9 with an upward opening is provided between the second limiting ring 4 and the exhaust duct 5. Since the powder is relatively heavy and will fall when the wind force is small, it can be used for recovery, while the dust will be sucked away. Further, a filter screen 90 is connected to the opening of the recovery duct 9. Some large particle impurities in the environment need to be filtered out.

[0023] The above is only the specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
