Description

Technical Field

[0001] The utility model relates to the technical field of printer equipment, in particular to a spiral powder feeding waste toner box with stable structure. Background Art

[0002] The waste toner box is mainly responsible for collecting the residual toner that the printer fails to transfer to the paper during the printing process, which is the so-called waste toner. If this waste toner remains inside the printer, it will not only contaminate the new toner, but also may affect the print quality.

[0003] At present, the waste toner boxes on the market are generally equipped with a spiral conveyor rod to sort out the accumulated materials in the waste toner box to prevent the waste powder from accumulating in the waste toner box. However, the spiral conveyor rod is made of elastic plastic. If it shakes during transportation, it can easily cause the spiral conveyor rod to fall into the waste toner box, resulting in the buyer being unable to use the product normally when receiving it, which brings a bad experience to the user and increases the cost of returning to the factory for repairs. Utility Model Content

[0004] In response to the problems existing in the prior art, this utility model proposes a spiral powder feeding waste powder bin with a stable structure, aiming to solve the problem of the spiral conveying rod falling during transportation and reduce the cost of returning to the factory for repairs.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a spiral powder feeding waste powder box with stable structure, which includes a box body, a spiral conveying rod and a driving gear. The spiral conveying rod is horizontally arranged in the box body and fixedly connected to the driving gear arranged at one end of the box body. The box body includes a bottom box and a box cover. The bottom box is provided with a first limit plate, and the box cover is provided with a plurality of second limit plates and a third limit plate. After the bottom box and the box cover are combined, the first limit plate is provided directly below the spiral conveying rod, and the second limit plate and the third limit plate are respectively provided on both sides directly above the spiral conveying rod, and a distance is left between the third limit plate and the spiral conveying rod.

[0006] Based on the above, a first limiting plate is provided on the bottom box. During transportation, when the spiral conveying rod shakes up and down, the first limiting plate will exert an upward supporting force on the spiral conveying rod, so that the spiral conveying rod will not fall down; a plurality of second limiting plates and a third limiting plate are provided on the box cover. The plurality of second limiting plates and third limiting plates are arranged in an array. The second limiting plate cooperates with the third limiting plate to limit the horizontal swing of the spiral conveying rod. The first limiting plate, the second limiting plate and the third limiting plate cooperate with each other to prevent the spiral conveying rod from swinging significantly during transportation and falling, causing economic losses. At the same time, a gap is left between the third limiting plate and the spiral conveying rod to avoid blocking the transmission of toner.

[0007] Furthermore, a powder inlet is provided on the upper surface of the box body and at one end close to the driving gear, and a transparent monitoring window is provided on the lower surface of the box body and at one end away from the driving gear. The monitoring window and the box body are an integrally formed structure.

[0008] Based on the above, the monitoring window and the box body are integrally formed by secondary injection molding, which can reduce the number of parts and assembly processes compared to traditional assembly methods, thereby reducing production costs and labor costs.

[0009] Furthermore, the spiral conveying rod is provided with a plurality of spiral blades, and a distance is left between any adjacent spiral blades.

[0010] Based on the above, a distance is provided between the spiral leaves, and the first limiting plate, the second limiting plate and the third limiting plate are provided in the section without spiral leaves to avoid interference with the spiral leaves.

[0011] Furthermore, the base box is provided with connecting columns, and the box cover is provided with connecting holes, and the base box and the box cover are installed by interference fit with the connecting columns through the connecting holes.

[0012] Based on the above, the base box and the box cover are installed by interference fit through the connecting holes and the connecting columns. Compared with the traditional method of fixing with screws, this installation method reduces the number of screw holes, improves the waterproof and dustproof effects, and is convenient for disassembly and assembly.

[0013] In order to more clearly illustrate the above features of the present invention and the objectives to be achieved, the present invention will be further described below with reference to the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] like Figures 1 to 4 As shown, a spiral powder feeding waste powder box with a stable structure includes a box body 1, a spiral conveying rod 2 and a driving gear 3. The driving gear 3 is arranged at one end of the box body 1. One end of the spiral conveying rod 2 passes through the box body 1 and is fixedly installed with the driving gear 3, and the other end cooperates with the mounting hole set in the box body 1. In the process of installing the spiral conveying rod 2 to the mounting hole, the spiral conveying rod 2 needs to be bent and then installed to the mounting hole. The spiral conveying rod 2 uses its own elasticity to restore its original shape. During transportation, severe vibrations will cause the spiral conveying rod 2 to bend significantly and fall from the mounting hole, thereby affecting the quality of the product. A first limit plate 6 is provided on the bottom box 4. The first limit plate 6 is provided directly below the spiral conveying rod 2 and just contacts the spiral conveying rod 2. The first limit plate 6 has an upward supporting force on the spiral conveying rod 2, so that the spiral conveying rod 2 will not fall downward. The box cover 5 is provided with a plurality of second limit plates 7 and a third limit plate 8. The second limit plate 7 and the third limit plate 8 are respectively provided on both sides directly above the spiral conveying rod 2. The second limit plate 7 and the third limit plate 8 cooperate to limit the horizontal swing of the spiral conveying rod 2. A gap is left between the third limit plate 8 and the spiral conveying rod 2. The first limit plate 6, the second limit plate 7 and the third limit plate 8 cooperate with each other to prevent the spiral conveying rod 2 from swinging greatly and falling during transportation, causing economic losses. At the same time, the gap left between the third limit plate 8 and the spiral conveying rod 2 can avoid blocking the transmission of carbon powder. The position settings of the first limit plate 6, the second limit plate 7 and the third limit plate 8 have been tested in multiple directions and can effectively realize the above functions in actual applications.

[0020] Preferably, a powder inlet 9 is provided on the upper surface of the box body 1, near the end of the drive gear 3, and a transparent monitoring window 10 is provided on the lower surface of the box body 1, away from the end of the drive gear 3. The monitoring window 10 and the box body 1 are integrally molded by a two-shot injection molding. Compared with traditional assembly methods, the two-shot injection molding can reduce the number of parts and assembly steps, thereby reducing production costs and labor costs.

[0021] Preferably, the spiral conveyor rod 2 is provided with a plurality of spiral blades 11, with spacing between any adjacent spiral blades 11. The first limiting plate 6, the second limiting plate 7 and the third limiting plate 8 are provided in sections without spiral blades 11 to avoid interference with the spiral blades 11.

[0022] Preferably, the base box 4 is provided with a connecting column 12, and the box cover 5 is provided with a connecting hole 13. The base box 4 and the box cover 5 are installed by interference fit with the connecting column 12 through the connecting hole 13. Compared with the traditional method of fixing with screws, while ensuring the tightness of its installation structure, this installation method also reduces the number of screw holes, improves the waterproof and dustproof effects, and is convenient for disassembly and assembly.

[0023] The specific implementation of this embodiment is as follows: the spiral conveying rod 2 is installed on the box body 1, and then the connecting hole 13 and the connecting column 12 are interference-fitted to fix the bottom box 4 and the box cover 5. For the convenience of installation, there is an installation gap between the spiral conveying rod 2 and the box body 1. The installation gap will not affect the normal operation of the waste powder box, but during transportation, large vibrations will cause the spiral conveying rod 2 to fall from the installation hole, thereby affecting the quality of the product. Therefore, the utility model is provided with the first limit plate 6, the second limit plate 7 and the third limit plate 8. The first limit plate 6, the second limit plate 7 and the third limit plate 8 cooperate with each other to prevent the spiral conveying rod 2 from swinging significantly during transportation and falling, causing economic losses. In addition, the monitoring window 10 is combined with the box body 1 by secondary injection molding. Compared with the traditional assembly method, this method can reduce the number of parts and assembly processes, reduce production costs and labor costs, and at the same time has high sealing performance to avoid powder leakage.

[0024] The above description is only the optimal solution embodiment of the present invention and is not intended to limit the present invention. Various modifications or replacements of the present invention made by those skilled in the art without departing from the essence and protection scope of the present invention should also be within the protection scope of the present invention.
