The technical scheme adopted by the utility model is as follows: the cleaning brush comprises a drum frame main body, a first end cover, a second end cover and a charging roller placing groove, wherein the first end cover and the second end cover are arranged at the left side end and the right side end of the drum frame main body, the charging roller placing groove is arranged at the inner side of the drum frame main body, a step layer is arranged at the bottom of the charging roller placing groove, the step layer and the drum frame main body are integrally formed in an injection molding mode, the outer portion of the step layer is of a hollow design, a pasting positioning opening is further formed in any end position of the left side and the right side of the step layer, a cleaning brush is pasted on the upper surface of the step layer, and one end of the cleaning brush penetrates through the pasting positioning opening and is reversely pasted on the outer side wall of the pasting positioning opening.

Further, the outer side of the step layer is of a hollow structure, and a plurality of reinforcing ribs are arranged in the hollow structure.

Further, a handle which is integrally injection molded with the drum frame body is further arranged at the bottom of the drum frame body, a waste powder bin is arranged in the handle, and a powder receiving port communicated with the waste powder bin is arranged on the step.

Further, a charging frame inner groove communicated with the charging roller placing groove is formed in the inner side of the first end cover, a guide groove is formed at the joint of the charging frame inner groove and the charging roller placing groove, a gear groove is formed in the inner side of the second end cover, and a charging roller reset mechanism is further arranged at the position where the gear groove is connected with the charging roller placing groove.

Finally, the charging roller reset mechanism comprises a sliding rail, a reset slide block in sliding fit with the sliding rail through a clamping groove, and a reset spring is arranged between the reset slide block and the bottom of the charging roller placing groove.

Compared with the prior art, the utility model has the beneficial effects that: compared with the conventional selenium drum skeleton in the market which is of a split type design, the selenium drum with small size like the HP219 is directly cancelled, the step layer is adopted to finish the pasting of the cleaning brush, so that the internal structure of the selenium drum is simplified, the product integrity is further optimized, the production efficiency of the product is improved, and the process of manual assembly is omitted. Therefore, the utility model simplifies the cleaning brush mounting structure, thereby optimizing the production and assembly procedures of the small selenium drum and effectively improving the production efficiency and the yield.

Detailed Description

As shown in fig. 1, 2 and 3, the utility model comprises a drum frame main body 1, a first end cover 2 and a second end cover 3 which are arranged at the left side end and the right side end of the drum frame main body 1, and a charging roller placing groove 4 which is arranged at the inner side of the drum frame main body 1, wherein a step layer 5 is arranged at the bottom of the charging roller placing groove 4, the step layer 5 and the drum frame main body 1 are integrally injection molded, the outside of the step layer is of a hollow design, a pasting positioning opening 6 is further arranged at any end position at the left side and the right side of the step layer 5, a cleaning brush 7 is pasted on the upper surface of the step layer 5, one end of the cleaning brush 7 passes through the pasting positioning opening 6 and is reversely pasted on the outer side wall of the pasting positioning opening 6, and when a worker pastes the cleaning brush 7, one end of the cleaning brush 7 passes through the pasting positioning opening 6 and is reversely pasted at the bottom to be positioned, and then the pasting of the cleaning brush 7 is completed, so that the installation accuracy of the cleaning brush 7 is ensured. The outer side of the step layer 5 is of a hollow structure, and a plurality of reinforcing ribs 8 are arranged in the hollow structure, so that the durability of the product is improved.

The utility model adopts an integral injection molding manufacturing mode, simplifies the structure inside the drum frame main body 1, thereby optimizing the production assembly process of the small-sized selenium drum and improving the production efficiency and the yield. The traditional cleaning brush needs to be adhered to the brush plate, a plurality of springs are often required to be arranged at the bottom of the brush plate to adapt to the size of the charging roller, an elastic buffer area is provided, the structure is too complex for the selenium drum with smaller size, such as the model HP219, which is mainly aimed at by the utility model, so that the production and installation efficiency is very low, the small-size selenium drum is easy to damage in the assembly process, the problem of adapting the charging roller does not exist, the complex structure is rather cumbersome, therefore, the utility model is replaced by the step layer 5, the actual height size of the step layer 5 can be changed through a die in the injection molding production according to different model requirements, and the cleaning brush 6 is adhered to the step layer 5, so that the mutual contact between the cleaning brush 6 and the charging roller is ensured, and the printing effect of the cleaning brush is ensured.
