Description

Technical Field

[0001] This utility model relates to the field of ballpoint pen refill technology, specifically to a ballpoint pen refill ink machine. Background Technology

[0002] Ballpoint pen refills come in a wide variety of types, varying in color, thickness, ink type, design, and brand to suit different needs. Common refill colors include black, blue, and red, and they also come in different thicknesses, from fine to thick nibs to meet various writing requirements.

[0003] A ballpoint pen refill machine (publication number: CN209616710U) disclosed in the public notice includes a refill machine body. The refill machine body includes a worktable, several pen refill positioners disposed on the worktable, and an ink injection mechanism. The worktable has an ink injection chamber inside, and several ink nozzles connected to the ink injection chamber and corresponding to the pen refill positioners are also provided on the worktable. The ink injection mechanism includes a fixed plate, a sliding plate slidably disposed below the fixed plate, and a positioning plate fixed to the worktable and located below the sliding plate. The fixed plate is fixed to the worktable by a support column at its bottom. A locking hole is provided on the sliding plate corresponding to the position of the positioning plate. An ink bag is provided on the positioning plate, and the bottom end of the ink bag is connected to the ink injection chamber. This utility model has a reasonable structural design, effectively preventing air bubbles from forming inside the pen refill during the refilling process and enabling simultaneous refilling of multiple pen refills, thus effectively improving the refilling efficiency.

[0004] The worktable, pen refill positioner, ink injection mechanism and other components in the above application work together to achieve the effect of air bubbles appearing inside the pen refill during the ink filling process and to fill multiple pen refills at the same time. However, they cannot achieve the effect of automatic feeding and stopping of pen refills. Therefore, we propose an ink filling machine for ballpoint pen refills. Utility Model Content

[0005] This utility model proposes an ink filling machine for ballpoint pen refills, which solves the problem of not being able to automatically feed and stop the refills in related technologies.

[0006] The technical solution of this utility model is as follows:

[0007] This utility model is a ballpoint pen refill machine, including a base, a connecting seat fixedly connected to the top of the base, and a feeding device provided on the side of the connecting seat.

[0008] Optionally, the feeding device includes a pump box, the side of which is fixedly connected to the side of the connecting seat. An inlet is provided at the top of the pump box. A piston at one end of the pump box is slidably connected to a force-bearing rod. A discharge pipe is fixedly connected to the bottom of the pump box. A conveying plate is fixedly connected to the side of the base. A motor is fixedly connected to the side of the conveying plate. A telescopic rod is fixedly connected to the output shaft of the motor. A push plate is fixedly connected to one end of the telescopic rod, and a striker is fixedly connected to the side of the telescopic rod. This feeding device design incorporates multiple mechanisms, utilizing components such as a motor, telescopic rod, and push plate to achieve precise material or liquid conveying. Specifically, the sliding piston and force-bearing rod in the structure can adjust the pressure and flow rate within the pump box, thereby regulating the material flow. Through reasonable fixing methods and moving parts, the system can operate efficiently and stably.

[0009] Optionally, one end of the force-bearing rod is located on the displacement trajectory of the impact rod, and the bottom of the discharge pipe is located on the displacement trajectory of the push plate. The force-bearing rod bears the impact force and transmits it to the system, while the discharge pipe ensures smooth material discharge.

[0010] Optionally, a rubber plug is inserted into the top of the feed inlet, and there is a gap between the side of the conveyor plate and the side of the push plate. The rubber plug is used to seal the feed inlet and prevent material leakage; while the gap between the conveyor plate and the push plate is mainly to ensure smooth material conveying, reduce friction and wear, and provide space for normal operation of the equipment.

[0011] Optionally, a return spring is fixedly connected to the circumferential surface of the force-bearing rod, with one end of the return spring fixedly connected to one end of the pump box. This design ensures that the system can automatically return to its initial state after being affected by external forces, avoiding permanent damage or malfunction of the equipment due to external forces. The return spring, by providing restoring force, helps reduce the long-term load on the force-bearing rod, while also increasing the stability and durability of the system.

[0012] Optionally, the initial state of the return spring is relaxed, and the initial state of the pump housing is closed. When the return spring is relaxed, the system does not apply additional force, ensuring that there is no unnecessary energy consumption or pressure when the equipment is shut down or in standby mode. The closed state of the pump housing ensures that the equipment is sealed and safe in the initial stage, preventing leakage or material spillage.

[0013] Optionally, a low-material warning device is provided at the bottom of the water pump tank. This device includes a switch, the bottom of which is located on the inner bottom of the water pump tank. A wire is electrically connected to the side of the switch, and one end of the wire is electrically connected to an indicator light. This low-material warning device allows the water pump tank to issue a timely warning when there is insufficient material or the liquid level is too low, ensuring the system can be replenished promptly and preventing equipment malfunction due to material shortage.

[0014] Optionally, a float plate is slidably connected to the inner side of the pump tank, and a pressure rod is fixedly connected to the bottom of the float plate. The float plate and the pressure rod are connected by a simple mechanical link and work together to support the pump tank level monitoring system. The float plate moves up and down according to changes in the water level, while the pressure rod transmits the movement signal of the float plate to activate the low-material warning device, ensuring that the liquid or material in the pump tank remains within the normal range and preventing system failure due to low material.

[0015] Optionally, the top of the switch is located on the movement trajectory of the pressure rod, and the bottom of the indicator light is fixedly connected to the side of the water pump tank. This system, through the linkage of the float, pressure rod, and switch, accurately senses changes in the liquid level inside the water pump tank and provides a real-time visual alarm signal via the indicator light.

[0016] The working principle and beneficial effects of this utility model are as follows:

[0017] 1. This utility model achieves automated ink filling by cooperating with components such as a motor, conveyor plate, telescopic rod, push plate, water pump box, and force-bearing rod. When the motor is started, it drives the telescopic rod to move horizontally. This horizontal movement of the telescopic rod drives the push plate to move horizontally, which in turn pushes the pen refill horizontally to directly below the discharge pipe. The horizontal movement of the telescopic rod then drives the impact rod to move horizontally, which in turn drives the internal piston of the force-bearing rod to move. This piston movement forces ink out of the discharge pipe and fills the pen refill. This achieves automated ink filling, improves work efficiency, and ensures efficient and stable operation.

[0018] 2. This utility model utilizes the coordinated operation of components such as a float plate, pressure rod, switch, and wires. When the ink level in the water pump tank is low, the float plate, under its own weight, drives the pressure rod to move vertically. This vertical movement of the pressure rod compresses the switch, energizing it and illuminating an indicator light via the wires. This alerts the operator that the ink level in the water pump tank is low, prompting the operator to add ink. This improves work efficiency and ensures the system can be replenished promptly, preventing equipment malfunction due to ink shortages. Attached Figure Description

[0030] Example 1

[0031] Reference Figures 1-5 The first embodiment of this utility model proposes a base 1, a connecting seat 2 fixedly connected to the top of the base 1, and a feeding device 3 provided on the side of the connecting seat 2.

[0032] The feeding device 3 includes a pump box 31, which is fixedly connected to the side of the connecting seat 2. An inlet 32 ​​is located at the top of the pump box 31. A piston at one end of the pump box 31 is slidably connected to a force-bearing rod 33. A discharge pipe 34 is fixedly connected to the bottom of the pump box 31. A conveying plate 35 is fixedly connected to the side of the base 1. A motor 36 is fixedly connected to the side of the conveying plate 35. A telescopic rod 37 is fixedly connected to the output shaft of the motor 36. A push plate 38 is fixedly connected to one end of the telescopic rod 37, and a striker 39 is fixedly connected to the side of the telescopic rod 37. This feeding device 3 incorporates multiple mechanisms, utilizing components such as the motor 36, telescopic rod 37, and push plate 38 to achieve precise material or liquid conveying. Specifically, the sliding piston and force-bearing rod 33 can adjust the pressure and flow rate within the pump box 31, thereby regulating the material flow. Through a reasonable fixing method and moving parts, the system can operate efficiently and stably.

[0033] One end of the force-bearing rod 33 is located on the displacement trajectory of the impact rod 39, and the bottom of the discharge pipe 34 is located on the displacement trajectory of the push plate 38. The force-bearing rod 33 bears the impact force and transmits it to the system, while the discharge pipe 34 ensures that the material is discharged smoothly.

[0034] A plug 310 is inserted into the top of the feed inlet 32, and there is a gap between the side of the conveyor plate 35 and the side of the push plate 38. The function of the plug 310 is to seal the feed inlet 32 ​​to prevent material leakage; while the gap between the conveyor plate 35 and the push plate 38 is mainly to ensure smooth material conveying, reduce friction and wear, and provide space for normal operation of the equipment.

[0035] A return spring 311 is fixedly connected to the circumferential surface of the force-bearing rod 33, with one end of the return spring 311 fixedly connected to one end of the pump box 31. This design ensures that the system can automatically return to its initial state after being affected by external forces, preventing permanent damage or malfunction of the equipment due to external forces. By providing restoring force, the return spring 311 helps reduce the long-term load on the force-bearing rod 33, while also increasing the stability and durability of the system.

[0036] The initial state of the return spring 311 is relaxed, and the initial state of the pump housing 31 is closed. When the return spring 311 is relaxed, the system does not apply additional force, ensuring that there is no unnecessary energy consumption or pressure when the equipment is shut down or in standby mode. The closed state of the pump housing 31 ensures that the equipment is sealed and safe in the initial stage, preventing leakage or material spillage.

[0037] In this embodiment, the motor 36 is started, and the motor 36 drives the telescopic rod 37 to move horizontally. The horizontal movement of the telescopic rod 37 drives the push plate 38 to move horizontally. The horizontal movement of the push plate 38 pushes the pen refill to move horizontally to directly below the discharge pipe 34. The horizontal movement of the telescopic rod 37 drives the impact rod 39 to move horizontally. The horizontal movement of the impact rod 39 pushes the force rod 33 to move its internal piston. The internal piston movement of the force rod 33 discharges ink from the discharge pipe 34 and fills the pen refill. When the force rod 33 loses its thrust, the force rod 33 is driven to return to its horizontal position by the elasticity of the return spring 311. When the force rod 33 returns to its horizontal position, the water pump box 31 loses its internal piston thrust, and the discharge pipe 34 stops discharging ink.

[0038] Example 2

[0039] Reference Figures 1-5 This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: a material shortage warning device 4 is provided at the bottom of the water pump tank 31. The material shortage warning device 4 includes a switch 41, the bottom of which is located on the inner bottom of the water pump tank 31. A wire 42 is electrically connected to the side of the switch 41, and one end of the wire 42 is electrically connected to an indicator light 43. Through this material shortage warning device 4, the water pump tank 31 can promptly issue a warning when the material is insufficient or the liquid level is too low, ensuring that the system can be replenished in a timely manner and preventing the equipment from malfunctioning due to material shortage.

[0040] A float plate 44 is slidably connected to the inner side of the water pump box 31, and a pressure rod 45 is fixedly connected to the bottom of the float plate 44. The float plate 44 and the pressure rod 45 work together through a simple mechanical connection to the water level monitoring system of the water pump box 31. The float plate 44 floats up and down according to changes in the water level, and the pressure rod 45 is used to transmit the movement signal of the float plate 44 to activate the low material reminder device 4, ensuring that the liquid or material in the water pump box 31 is kept within the normal range and avoiding system failure due to low material.

[0041] The top of switch 41 is located on the movement trajectory of pressure rod 45, and the bottom of indicator light 43 is fixedly connected to the side of water pump tank 31. Through the linkage of float plate 44, pressure rod 45 and switch 41, the system accurately senses the liquid level change inside water pump tank 31 and provides a real-time visual alarm signal through indicator light 43.

[0042] Compared to Embodiment 1, further, when the ink in the water pump tank 31 is insufficient, the float 44 drives the pressure rod 45 to move vertically by its own gravity. The vertical movement of the pressure rod 45 squeezes the switch 41, and the switch 41 is energized by the squeeze. The indicator light 43 is lit through the wire 42, thereby reminding the operator that the ink in the water pump tank 31 is insufficient, so that ink can be added.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
