[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 , Figure 2 and Figure 5, an embodiment of the utility model provides: a toner cartridge gear fixing frame, comprising a cover plate 1, a developing cover 2 is fixedly connected to the outside of the cover plate 1, a powder conveying cover 3 is fixedly connected to the outside of the cover plate 1, a driving cover 4 is fixedly connected to the outside of the cover plate 1, two connecting grooves 17 are provided on the outside of the cover plate 1, a baffle 19 is slidably connected to the inner wall of the connecting groove 17, a pull rod 5 is fixedly connected to one side of the baffle 19, a spring 18 is sleeved on the outside of the pull rod 5, a clamping block 20 is fixedly connected to the other side of the baffle 19, two mounting grooves 15 are provided on the outside of the cover plate 1, a cover plate 22 is slidably connected to the outside of the cover plate 1, a powder conveying pipe 8 is fixedly connected to the outside of the cover plate 22, a developing pipe 6 is fixedly connected to the outside of the cover plate 22, a driving pipe 7 is fixedly connected to the outside of the cover plate 22, two mounting blocks 16 are fixedly connected to the outside of the cover plate 22, a clamping groove 21 is provided on the outside of the mounting block 16, and an extrusion component is installed inside the cover plate 1.

[0032] Specifically, when it is necessary to remove the cover 1, pull the pull rod 5, and the pull rod 5 drives the baffle 19 to slide along the inner wall of the connecting groove 17, thereby driving the block 20 to slide until the block 20 is completely retracted into the inside of the connecting groove 17. At the same time, pull the cover 1 to disengage the mounting block 16 from the mounting groove 15, and complete the removal of the cover 1. When it is necessary to install the cover 1, pull the pull rod 5 to repeat the above steps, so that the spring 18 is in a compressed state. At the same time, push the cover 1 to make the mounting block 16 snap into the inside of the mounting groove 15. At this time, the outer side of the cover 1 is fitted with the outer side of the cover 22, release the pull rod 5, and under the elastic force of the spring 18, the baffle 19 is reset, and then the block 20 is inserted into the slot 21, that is, the installation of the cover 1 is completed. By disassembling and installing the cover 1, the disassembly process of the gear fixing frame is faster and more efficient, which can reduce downtime and improve the availability and production efficiency of the equipment.

[0033] Reference Figure 1 and Figure 3 The extrusion assembly includes a support member 10, which is fixedly connected to the outer side of the cover plate 1, and a motor 14 is fixedly connected to the outside of the support member 10. A bidirectional threaded rod 11 is rotatably connected to the outer side of the support member 10, and the outer threads of the bidirectional threaded rod 11 are connected to two sliders 12. An oil bottle 13 is fixedly connected to the outer side of the cover plate 1, and a conduit 9 is fixedly connected to the bottom of the oil bottle 13.

[0034] Specifically, the motor 14 is started, and the output end of the motor 14 drives the bidirectional threaded rod 11 to rotate, and then under the action of the bidirectional threaded rod 11, the two sliders 12 are brought close to each other, and then the two extrusion plates are driven to squeeze the oil bottle 13, so that the lubricating oil enters the conduit 9. Under the transportation of the conduit 9, the lubricating oil drips on the surface of each gear, and the gears are lubricated by automatically squeezing the oil bottle 13, which can improve the operating stability of the toner cartridge gear fixing frame, reduce equipment failures and shutdowns caused by insufficient or uneven lubrication, and help maintain the stable operation of the production line.

[0035] Reference Figure 3 and Figure 4 A sealing strip 23 is fixedly connected to the outer side of the cover plate 1, and a sealing groove 24 is opened on the outer side of the cover plate 22.

[0036] Specifically, under the action of the sealing strip 23 and the sealing groove 24, the noise generated by the gear transmission can be reduced, the vibration and mechanical interference can be reduced, and it is helpful to improve the product assembly quality.

[0037] Reference Figure 5 One end of the spring 18 is fixedly connected to the outer side of the baffle 19 , and the other end of the spring 18 is fixedly connected to the inner wall of the connecting groove 17 .

[0038] Specifically, the baffle plate 19 is limited and fixed by the spring 18 to prevent the baffle plate 19 from sliding freely along the inner wall of the connecting groove 17, thereby further improving the stability of the connection between the cover plate 1 and the cover plate 2 22.

[0039] Reference Figure 5 The longitudinal section of the card block 20 is a square, and the card block 20 and the card slot 21 are plug-fitted.

[0040] Specifically, by snapping the snap block 20 into the snap slot 21 , the cover plate 22 is made more stable, thereby ensuring the reliability of the connection between the cover plate 1 and the cover plate 2 22 .

[0041] Reference Figure 3 The bottoms of the two sliders 12 are fixedly connected with extrusion plates, and the outsides of the extrusion plates are fixedly connected with rubber pads.

[0042] Specifically, the two extrusion plates are driven to approach each other by the slider 12 to squeeze the oil bottle 13, so that the parts are always kept in a good lubrication state, thereby improving the production efficiency of the equipment.

[0043] Reference Figure 3 The connection of the conduit 9 is connected through a three-way valve, and the conduit 9 is made of a hard material.

[0044] Specifically, the three-way valve is used to enable the conduit 9 to have multiple forks, so that the lubricating oil in the conduit 9 can lubricate the gears more accurately. The hard material can prevent the conduit 9 from being deformed due to shaking or vibration, thereby causing waste of lubricating oil.

[0045] Reference Figure 1 and Figure 5 One end of the pull rod 5 passes through the cover plate 1 and extends to the outside, and the outside of the pull rod 5 is provided with anti-slip grooves.

[0046] Specifically, it is convenient for the user to pull the pull rod 5 to disassemble or install the device, and the anti-slip pattern can increase the friction force, so that the user can better control the pull rod 5.

[0047] Working principle: when it is necessary to remove the cover 1, pull the pull rod 5 to make the baffle 19 slide along the inner wall of the connecting groove 17, thereby driving the card block 20 to slide, so that the card block 20 is separated from the card slot 21. At the same time, pull the cover 1 to make the mounting block 16 disengage from the mounting groove 15, that is, the removal of the cover 1 is completed. When it is necessary to install the cover 1, pull the pull rod 5 and repeat the above steps to make the spring 18 in a compressed state. At this time, push the cover 1 to make the mounting block 16 fit the inner wall of the mounting groove 15, release the pull rod 5, and under the elastic force of the spring 18, the baffle 19 is reset, so that the card block 20 is inserted into the card slot 21, that is, the installation of the cover 1 is completed. By removing and installing the cover 1, the toner cartridge gear fixing frame is easier to maintain and maintain, saving maintenance time and labor costs.

[0048] In addition, the motor 14 is started, and the output end of the motor 14 drives the bidirectional threaded rod 11 to rotate, and then the two sliders 12 are moved closer to each other through the rotation of the bidirectional threaded rod 11, and then the two extrusion plates are driven closer to each other, and the oil bottle 13 is squeezed by the two extrusion plates, so that the lubricating oil drips onto the surface of each gear through the conduit 9. The gears are lubricated by automatically squeezing the oil bottle 13, which can ensure that the gears, bearings and other components always maintain a good lubrication state during the working process, which helps to reduce friction and wear between components and extend their service life.

[0049] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
