Description

Technical Field

[0001] This utility model relates to the technical field of printer consumables maintenance equipment, specifically an auxiliary positioning device for refilling toner cartridges. Background Technology

[0002] Toner cartridge refilling is a crucial process for maintaining the normal operation and print quality of a printer. The accuracy and efficiency of toner delivery directly affect the refilling results. During this process, an auxiliary positioning device is needed to position and support the toner cartridge.

[0003] The existing patent document CN222629708U provides an auxiliary positioning device for toner cartridge filling. This utility model has a return spring between the limiting plate and the support plate. The operator presses the return spring to place the toner cartridge on the limiting plate, and the toner cartridge is fixed by the stabilizing mechanism, which improves the stability of the toner cartridge during filling. After filling is completed, the operator presses down on the limiting plate to remove the toner cartridge, thus solving the problem of the fixed support distance and the inconvenience of removing the toner cartridge.

[0004] However, existing auxiliary positioning devices for toner cartridge refilling lack dynamic monitoring of the force applied to the toner cartridge. During the toner cartridge clamping process, existing auxiliary positioning devices cannot sense and adjust the pressure in real time. This can easily lead to damage to the toner cartridge due to uneven force or excessive pressure, such as wear on the surface coating and deformation of the internal structure. In particular, for toner cartridges of different models and materials, the fixed clamping force cannot meet the differentiated needs. At the same time, the lack of force monitoring also means that if the toner cartridge is slightly displaced or loosened during the refilling process, the equipment cannot provide timely feedback and adjustment, which will affect the refilling accuracy and even cause problems such as toner spillage and blockage, reducing the refilling efficiency and success rate. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] The purpose of this invention is to provide an auxiliary positioning device for refilling toner cartridges, in order to solve the problem mentioned in the background art that existing auxiliary positioning devices for refilling toner cartridges lack a dynamic monitoring mechanism for the force applied to the toner cartridge.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary positioning device for refilling toner cartridges, comprising a rectangular base, a positioning groove formed in the middle of the upper surface of the rectangular base, and arc-shaped plates symmetrically arranged on both sides of the positioning groove above the rectangular base, with pressure sensors installed on the inner sides of the arc-shaped plates.

[0009] A stabilizing plate is connected to the side of the pressure sensor away from the arc plate. The side of the stabilizing plate away from the pressure sensor is covered with an anti-slip rubber layer. A control panel is integrated on the upper surface of the rectangular base. The control panel is electrically connected to the pressure sensor.

[0010] As a further improvement to the above solution, a mounting bracket is provided on one side of the upper surface of the rectangular base, and a positioning motor is installed on one side inside the mounting bracket. The transmission end of the positioning motor is fixedly connected to a bidirectional lead screw.

[0011] As a further improvement to the above solution, the end of the bidirectional lead screw away from the positioning motor is connected to the mounting bracket via a bearing, and the outer surface of the bidirectional lead screw is connected to an internal thread positioning plate via a thread, the internal thread positioning plate being in sliding fit with the mounting bracket.

[0012] As a further improvement to the above solution, the arc-shaped plate is fixed to the inner side of the internal thread positioning plate, a top plate is provided above the rectangular base, and a hydraulic cylinder is installed at the bottom end of the top plate.

[0013] As a further improvement to the above solution, an adjusting rod is fixedly connected to the transmission end at the bottom of the hydraulic cylinder, a support frame is fixedly connected to the bottom end of the adjusting rod, and a powder storage tank is fixed in the middle of the support frame.

[0014] As a further improvement to the above solution, a horizontally arranged powder filling guide cylinder is fixedly connected to the bottom of the powder storage tank. A micro motor is installed on one side of the powder filling guide cylinder, and a spiral vane powder feeding shaft is fixedly connected to the transmission end of the micro motor through the cylinder wall.

[0015] As a further improvement to the above solution, a powder filling interface is connected to one side of the bottom end of the powder filling guide cylinder, and the powder filling interface is perpendicularly corresponding to the positioning groove.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This auxiliary positioning device for toner cartridge refilling achieves flexible clamping and stable fixation of the toner cartridge by setting up a pressure sensor and an anti-slip rubber layer. The pressure sensor senses the clamping force of the curved plate on the toner cartridge in real time. If the force is too large, it will be fed back to the control panel to adjust the clamping state in time, so as to avoid damage to the toner cartridge due to uneven force or excessive pressure. The anti-slip rubber layer is covered on the surface of the stabilizing plate. Utilizing its own high friction and elasticity, it fits tightly against the surface of the toner cartridge, which can not only prevent the toner cartridge from shifting during the refilling process, but also reduce the wear caused by mechanical contact to the toner cartridge through the buffering effect. Compared with the traditional rigid clamping method, it greatly improves the safety and stability of toner cartridge refilling.

[0018] 2. This auxiliary positioning device for toner cartridge filling constructs an automated positioning structure by setting a positioning motor. The positioning motor drives the bidirectional lead screw to rotate, causing the two arc plates on both sides to move synchronously towards or away from each other, realizing automatic centering and clamping of toner cartridges of different sizes. This structure can dynamically adjust the clamping position according to the diameter of the toner cartridge, eliminating the need for manual measurement and adjustment, greatly shortening the positioning time and improving the operating efficiency. At the same time, the positioning motor and pressure sensor form a closed-loop control. When the arc plate contacts the toner cartridge and reaches the set pressure threshold, the motor automatically cuts off the power and locks the position, which not only ensures the clamping stability but also avoids the deformation of the toner cartridge due to excessive compression, significantly improving the reliability of the toner filling operation.

[0019] 3. This auxiliary positioning device for toner cartridge refilling constructs a highly efficient toner delivery system by setting up a micro motor and a spiral blade toner delivery shaft. The micro motor drives the spiral blade to rotate at a constant speed inside the toner guide cylinder. The spiral blade pushes the toner in the storage tank to the refilling interface stably. Compared with the traditional gravity-flow toner filling method, this design improves the toner delivery efficiency and can precisely control the filling amount by adjusting the motor speed, avoiding blockage of the refilling port due to toner accumulation. At the same time, the continuous rotation of the spiral blade toner delivery shaft can break up toner clumps, ensuring that the toner particles are evenly distributed during the delivery process. Combined with the precise docking of the refilling guide cylinder and the toner cartridge refilling port, it effectively reduces toner overflow, significantly improving the cleanliness and success rate of the refilling operation.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 - Figure 4 This utility model provides a technical solution: an auxiliary positioning device for refilling toner cartridges, including a rectangular base 1, a positioning groove 2 is provided in the middle of the upper surface of the rectangular base 1, and arc plates 3 are symmetrically arranged on both sides of the positioning groove 2 above the rectangular base 1, and pressure sensors 4 are installed on the inner side of the arc plates 3.

[0027] A stabilizing plate 5 is connected to the side of the pressure sensor 4 away from the arc plate 3. The side of the stabilizing plate 5 away from the pressure sensor 4 is covered with an anti-slip rubber layer 6. A control panel 7 is integrated on the upper surface of the rectangular base 1. The control panel 7 is electrically connected to the pressure sensor 4.

[0028] The pressure sensor 4 on the inner side of the arc plate 3 transmits the pressure signal to the control panel 7 in real time when the stabilizing plate 5 contacts the toner cartridge. When the pressure reaches the preset value, the control panel 7 controls the positioning motor 9 to stop running. At this time, the anti-slip rubber layer 6 is tightly attached to the surface of the toner cartridge, ensuring stable clamping while avoiding damage to the surface of the toner cartridge. During the toner filling process, the pressure sensor 4 continuously monitors the force on the toner cartridge. If the force on the toner cartridge changes due to toner filling, the control panel 7 can adjust the forward and reverse rotation of the positioning motor 9, the lifting and lowering of the hydraulic cylinder 13, or the speed of the micro motor 18 in a timely manner to ensure stable toner filling.

[0029] A mounting bracket 8 is located on one side of the upper surface of the rectangular base 1. A positioning motor 9 is installed inside the mounting bracket 8 on one side. A bidirectional lead screw 10 is fixedly connected to the transmission end of the positioning motor 9. The end of the bidirectional lead screw 10 away from the positioning motor 9 is connected to the mounting bracket 8 via a bearing. An internally threaded positioning plate 11 is threadedly connected to the outer surface of the bidirectional lead screw 10. The internally threaded positioning plate 11 slides with the mounting bracket 8. An arc-shaped plate 3 is fixed to the inner side of the internally threaded positioning plate 11. A top plate 12 is provided above the rectangular base 1. A liquid is installed at the bottom end of the top plate 12. The hydraulic cylinder 13 has an adjusting rod 14 fixedly connected to its transmission end at the bottom. The bottom end of the adjusting rod 14 is fixedly connected to a support frame 15. A powder storage tank 16 is fixedly fixed in the middle of the support frame 15. A horizontally arranged powder filling guide cylinder 17 is fixedly connected to the bottom end of the powder storage tank 16. A micro motor 18 is installed on one side of the powder filling guide cylinder 17. The transmission end of the micro motor 18 is fixedly connected to a spiral vane powder feeding shaft 19 through the cylinder wall. A powder filling interface 20 is connected to one side of the bottom end of the powder filling guide cylinder 17. The powder filling interface 20 is perpendicularly corresponding to the positioning groove 2.

[0030] After placing the toner cartridge in the positioning slot 2 of the rectangular base 1, start the positioning motor 9, which drives the bidirectional lead screw 10 to rotate, causing the two internal thread positioning plates 11 on both sides to slide towards each other along the slide rail of the mounting bracket 8. This causes the arc plate 3 fixed on the inner side to move closer to the toner cartridge simultaneously. After the toner cartridge is positioned, the hydraulic cylinder 13 at the bottom of the top plate 12 is activated, pushing the adjusting rod 14 and the support frame 15 below to move vertically downwards. This causes the filling guide cylinder 17 at the bottom of the toner storage tank 16 to descend until the filling interface 20 is precisely aligned with the toner cartridge filling port. Subsequently, the micro motor 18 drives the spiral blade feeding shaft 19 to rotate inside the filling guide cylinder 17, pushing the toner in the toner storage tank 16 into the toner cartridge at a uniform speed. After filling is completed, the hydraulic cylinder 13 drives the filling guide cylinder 17 to rise and reset. The positioning motor 9 reverses to separate the arc plate 3, allowing the toner cartridge to be easily removed.

[0031] Working principle: After placing the toner cartridge in the positioning slot 2 of the rectangular base 1, the positioning motor 9 is started, which drives the bidirectional lead screw 10 to rotate, causing the two internal thread positioning plates 11 on both sides to slide towards each other along the slide rail of the mounting bracket 8. This causes the arc-shaped plate 3 fixed on the inner side to move closer to the toner cartridge simultaneously. The pressure sensor 4 on the inner side of the arc-shaped plate 3 transmits the pressure signal to the control panel 7 in real time when the stabilizing plate 5 contacts the toner cartridge. When the pressure reaches the preset value, the control panel 7 controls the positioning motor 9 to stop running. At this time, the anti-slip rubber layer 6 tightly adheres to the surface of the toner cartridge, ensuring stable clamping while avoiding damage to the surface of the toner cartridge. After the toner cartridge is positioned, the hydraulic cylinder 13 at the bottom of the top plate 12 is activated, pushing the adjusting rod 14 and the support frame below. 15 moves vertically downward, causing the filling guide cylinder 17 at the bottom of the toner storage tank 16 to descend until the filling interface 20 is precisely aligned with the toner cartridge filling port. Subsequently, the micro motor 18 drives the spiral blade feeding shaft 19 to rotate inside the filling guide cylinder 17, pushing the toner in the storage tank 16 into the toner cartridge at a uniform speed. During the filling process, the pressure sensor 4 continuously monitors the force on the toner cartridge. If the force on the toner cartridge changes due to toner filling, the control panel 7 can adjust the forward and reverse rotation of the positioning motor 9, the lifting and lowering of the hydraulic cylinder 13, or the speed of the micro motor 18 in a timely manner to ensure stable filling. After filling is completed, the hydraulic cylinder 13 drives the filling guide cylinder 17 to rise and reset, and the positioning motor 9 reverses to separate the arc plate 3, allowing the toner cartridge to be easily removed.
