[0025] The technical solutions in the utility model will be described clearly and completely below in combination with the drawings in the utility model.

[0026] Embodiment one: the selenium drum powder filling device provided by the utility model is mainly composed of a device main body 100, wherein the device main body 100 comprises the following key components:

[0027] The powder storage bottle 110 is designed as a funnel-shaped structure with an open top end and is made of transparent material, which enables the operator to intuitively observe the storage amount of the carbon powder in the powder storage bottle 110. The bottom end of the powder storage bottle 110 is in communication with the powder filling pipe 111, and the powder filling pipe 111 serves as a channel for carbon powder delivery and can be precisely inserted into the powder filling port of the selenium drum, thereby realizing the function of smoothly delivering the carbon powder in the powder storage bottle 110 to the inside of the selenium drum.

[0028] Sealing assembly: installed at the top end of the toner bottle 110, specifically including a sealing cover 112, an internal thread 113 and an external thread 114. The inner side of the sealing cover 112 is processed with the internal thread 113, and the outer surface of the toner bottle 110 is provided with the external thread 114 at the corresponding position. Through the close cooperation of the threads, the operator can easily install the sealing cover 112 at the top end of the toner bottle 110 to form a reliable sealing structure, effectively preventing the carbon powder from flying and leaking during storage and transportation, keeping the working environment clean, and reducing the waste of carbon powder.

[0029] Quantitative mechanism: provided on the toner bottle 110, mainly composed of a scale line 115 and an on-off assembly. The scale line 115 is clearly marked along the side wall of the toner bottle 110, providing an intuitive reference for the carbon powder capacity for the operator, so that he can accurately control the powder filling amount according to the actual demand of the selenium drum. The on-off assembly is located at the powder filling pipe 111 and is composed of an insertion box 116, an insertion plate 117 and a handle 118. The insertion box 116 is firmly installed on the powder filling pipe 111, and the insertion plate 117 can be smoothly inserted into the insertion box 116 through the insertion slot, thereby realizing the sealing effect of the powder filling pipe 111. The handle 118 is connected to one side of the insertion plate 117, which is convenient for the operator to hold and operate. When filling powder is needed, the operator can pull out the insertion plate 117 through the handle 118 to open the powder filling channel; after the powder filling is completed, the insertion plate 117 is inserted again to close the powder filling pipe 111 to prevent carbon powder leakage.

[0030] Example two

[0031] In the design of example two, further optimization and improvement are made on the basis of example one, as follows:

[0032] Improved powder filling pipe: the bottom edge of the powder filling pipe 111 is specially designed as an arc-shaped part 119, and the arc of the arc-shaped part 119 is precisely matched with the edge arc of the common selenium drum powder filling port on the market after careful research and testing. In actual powder filling operation, this design not only makes the powder filling pipe 111 more smoothly inserted into the powder filling port, avoiding damage to the powder filling port due to improper insertion, but also ensures that the powder filling pipe 111 and the powder filling port form a good sealing connection, effectively preventing the carbon powder from leaking during powder filling, improving the accuracy and stability of powder filling.

[0033] Anti-slip design: In order to improve the holding stability of the operator during use, anti-slip lines are added to the outer surface of the powder storage bottle 110. These anti-slip lines are evenly distributed along the height direction of the powder storage bottle 110, and their shapes can be wavy or strip-shaped, etc. with good anti-slip effect. When the operator holds the powder storage bottle 110 to perform powder filling operation, the anti-slip lines can significantly increase the friction between the hand and the powder storage bottle 110, effectively preventing the device from falling or inaccurate powder filling due to slippery hands, thereby greatly improving the safety and stability of the operation, ensuring that the powder filling process can be smoothly and accurately completed.

[0034] Sealing performance enhancement: A sealing rubber strip is added to the contact surface between the insertion plate 117 and the insertion box 116. The sealing rubber strip is arranged tightly around the edge of the insertion plate 117, and when the insertion plate 117 is inserted into the insertion box 116, the sealing rubber strip will be extruded to elastically deform, thereby filling the small gap between the insertion plate 117 and the insertion box 116, further enhancing the sealing performance between the two. This design can more effectively prevent carbon powder from leaking from the powder filling tube 111 in the non-powder filling state, ensuring the sealing and reliability of the device during the entire use cycle, reducing unnecessary loss of carbon powder and pollution to the environment.

[0035] Anti-static treatment: Considering that carbon powder is easily affected by static electricity during storage and powder filling, which may cause agglomeration and affect the efficiency and quality of powder filling, a layer of anti-static coating is applied to the inner wall of the powder storage bottle 110. The anti-static coating is made of advanced organic polymer material, which has good conductivity and stability. In actual application, the anti-static coating can timely guide away the static electricity generated during the flow of carbon powder, effectively reducing the agglomeration of carbon powder due to static adsorption, ensuring that the carbon powder can flow uniformly and smoothly through the powder filling tube 111 for powder filling. This not only improves the efficiency and quality of powder filling, but also ensures the stability and reliability of the print effect of the selenium drum during use, providing high-quality print output for users.

[0036] Through the detailed description of the above two embodiments, the unique features and advantages of the selenium drum powder filling device of the present application in structure design and function realization can be clearly seen, which can effectively solve many problems existing in the current selenium drum powder filling process, and provide a more efficient, convenient, environmentally friendly and reliable powder filling solution for users. In actual production and application, the design scheme of example one or example two can be selected according to specific needs and cost considerations to meet the diversified needs of different users.
