[0002] A toner cartridge is an accessory for storing and loading toner. It usually includes a plastic cylinder and a hole for filling toner. Its function is to load toner powder into the printer and cooperate with the toner cartridge to complete the printing job. To prevent the toner cartridge from leaking powder during transportation and use, a sealing sponge needs to be pasted at the hole during the assembly of the finished toner cartridge. The existing process is to paste the sealing sponge at the hole by hand and press it. This process is prone to the problem of skewed pasting and not being in place, which requires rework, has poor workmanship, and affects efficiency, especially for novice operators.

For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] The utility model provides a powder cartridge sealing sponge pasting auxiliary device, such as Figure 1 and Figure 3 As shown, it includes a base 10 and a limiting bracket 20 that cooperate with each other, wherein a portion is provided on the base 1 for placing a sealing sponge 40 to be pasted, the limiting bracket 20 cooperates with the powder tube 30, and a limiting structure is provided between the base 10 and the limiting bracket 20, so that the limiting bracket 20 can move vertically toward the sealing sponge 40 with the powder tube 30, thereby ensuring that the sealing sponge 40 can be smoothly pasted to the powder tube 30.

[0028] Specifically, in this embodiment, a limiting groove 11 for placing the sealing sponge 40 is opened on the base 10, and the limiting bracket 20 cooperates with the powder tube 30. Then, the limiting structure is used to make the limiting bracket 20 face the limiting groove 11, and the limiting bracket 20 is moved so that the powder tube 30 can face the sealing sponge 40, so that the sealing sponge 40 is stably adhered to the powder tube 30, and then the powder tube 30 and the limiting bracket 20 can be separated.

[0029] like Figure 2 and Figure 5 As shown, the limiting structure includes a guide rod 12 vertically installed on the base 10. In this embodiment, two guide rods 12 are provided, and the guide rods 12 are symmetrically arranged along the limiting groove 11. A guide hole 21 is opened at the position of the limiting bracket 20 corresponding to the guide rod 12, and the guide rod 12 is inserted into the corresponding guide hole 21. Under the action of the guide rod 12, the limiting bracket 20 can be moved opposite to the limiting groove 11.

[0030] Specifically, Figure 2 and Figure 4 As shown, in this embodiment, the guide rod 12 is located between the base 10 and the limit bracket 20 and is sleeved with a compression spring 13. When the limit bracket 20 is pressed downward, the compression spring 13 is compressed. When the limit bracket 20 is released, the compression spring 13 lifts the limit bracket 20, thereby separating the base 10 from the limit bracket 20, achieving a semi-automatic effect, thereby facilitating user use. In order to make the limit bracket 20 move more smoothly on the guide rod 12, a linear bearing 22 is provided in the guide hole 21, and the guide rod 12 is inserted into the linear bearing 22.

[0031] like Figure 2 and Figure 3 As shown, a mounting hole 14 is provided at a position of the base 10 corresponding to the guide rod 12, and the guide rod 12 is inserted into the mounting hole 14. At the same time, a receiving groove 18 is provided at the top of the mounting hole 14. When the compression spring 13 is compressed, the compression spring 13 slowly enters the receiving groove 18, so that the limit bracket 20 and the base 10 can fit more closely, ensuring that the sealing sponge 40 is better adhered to the powder tube 30.

[0032] In order to prevent the guide rod 12 from slipping out of the mounting hole 14 and the guide hole 21, a slot 15 is provided on the side surfaces at both ends of the guide rod 12, and a retaining spring 16 is installed on the slot 15. The retaining spring 16 can prevent the guide rod 12 from being separated from the base 10 and the limiting bracket 20. At the same time, in order to enable the base 10 to be stably placed on the platform, a receiving groove 17 is provided on the bottom surface of the base 10 corresponding to the retaining spring 16 at the bottom of the guide rod 12, which is used to hide the end of the guide rod 12, so that the base 10 can be stably placed on the platform, which is convenient for users to operate.

[0033] At the same time, if Figure 5 As shown, in order to enable the limiting bracket 20 to be smoothly connected to and separated from the powder cartridge 30, in the present embodiment, a step 31 is provided on the powder cartridge 30, and a boss 23 is provided at the position of the inner circle of the limiting bracket 20 corresponding to the step 31. When the powder cartridge 30 is pushed to move downward, the step 31 cooperates with the boss 23, thereby pushing the limiting bracket 20 to move. Under the action of the guide rod 12, the limiting bracket 20 can move vertically toward the sealing sponge 40 with the powder cartridge 30. After the sealing sponge 40 is pasted, the powder cartridge 30 can be separated from the limiting bracket 20 by moving upward. At the same time, the compression spring 13 also lifts the limiting bracket 20 to expose the limiting groove 11. Subsequently, a new sealing sponge 40 is placed on the limiting groove 11, and the step 31 on the new powder cartridge 11 cooperates with the step 23, and the powder cartridge 30 is pressed downward again, so that the new powder cartridge 30 and the new sealing sponge 40 are pasted together, thereby realizing repeated operations, greatly improving work efficiency, and achieving better pasting effects.

[0034] It should be understood that the above description of the specific embodiments of the utility model is only for illustrating the technical route and features of the utility model, and its purpose is to enable those skilled in the art to understand the content of the utility model and implement it accordingly, but the utility model is not limited to the above specific implementation methods. All changes or modifications made within the scope of the claims of the utility model should be included in the protection scope of the utility model.
