Description

Technical Field

[0001] This utility model belongs to the field of printing consumables production equipment, specifically relating to an ink bag production equipment. Background Technology

[0002] Ink bags, also known as inkjet ink cartridge inner bags, are used as printing consumables when installed on inkjet printers. Currently, the assembly and filling of ink bags adopt a decentralized single-station operation mode: internal components such as springs, steel balls, and sealing rings are mostly assembled manually one by one. The filling process is set up independently with few stations, and the sealing process requires a separate transfer line. This mode has decentralized processes, long material turnover paths, low overall production efficiency, high labor costs, poor consistency of manual assembly, high risk of missing or incorrect assembly, and reliance on manual visual inspection, resulting in a high rate of missed inspections and unstable product yield. The filling stations are mostly single-path or a few parallel operations, resulting in poor ink supply continuity, insufficient ink volume control precision, and problems such as uneven ink filling and ink overflow and waste. The lack of linkage positioning between processes leads to repeated clamping, causing cumulative positioning errors and affecting the accuracy of assembly and filling. Therefore, in order to avoid the shortcomings of the existing technology, it is necessary to improve the existing technology. Utility Model Content

[0022] Please refer to the following: Figures 1 to 7The ink bag production equipment provided in the embodiments of this utility model will now be described.

[0023] like Figures 1 to 7 As shown, the ink bag production equipment of this utility model includes a transfer device 100, a spring steel ball assembly mechanism 200, a sealing ring assembly mechanism 300, a quantitative ink filling mechanism, and a sealing film mechanism 600. The transfer device 100 is a rotary table structure. A clamping and positioning carrier 110 is arranged along the circumference of the transfer device 100, which can clamp the outer ring of the ink bag's bottle mouth. An unloading / loading station is provided at the starting end of the transfer device 100. The spring steel ball assembly mechanism 200 is distributed along the transfer device 100 at the rear end of the unloading / loading station. The spring steel ball assembly mechanism 200 can assemble springs and steel balls into the cavity of the ink bag and perform assembly testing. The sealing ring assembly mechanism 300 is distributed along the transfer device 100 at the rear end of the spring steel ball assembly mechanism 200. At the rear end, the sealing ring assembly mechanism 300 can press the sealing ring into the corresponding slot of the ink bag. The quantitative ink filling mechanism is distributed at the rear end of the sealing ring assembly mechanism 300 along the transfer device 100. The quantitative ink filling mechanism includes an ink filling device 400 and a quantitative ink storage device 500. The ink filling device 400 and the quantitative ink storage device 500 are connected. The ink filling device 400 is set above the clamping and positioning carrier 110. The ink filling device 400 is provided with a number of ink filling connectors 410. The ink filling connectors 410 are aligned with the opening of the ink bag. The quantitative ink storage device 500 and the ink filling device 400 are also connected by an ink recycling tank 510. The sealing film mechanism 600 is set at the end of the transfer device 100. The sealing film mechanism 600 can heat-seal the sealing film to the ink filling port of the ink bag.

[0024] Specifically, a solenoid valve is installed on the connecting pipe between the ink filling device 400 and the quantitative ink storage device 500 to control the ink output. A solenoid valve is also installed on the bypass pipe connected to the ink recovery tank 510 to recover overflowing ink.

[0025] like Figures 4-5 As shown, the spring ball assembly mechanism 200 includes a spring vibrating feeder 211 and a spring assembly device 210. The spring vibrating feeder 211 is connected to a spring conveying track 212, and the end of the spring conveying track 212 is connected to the spring assembly device 210. The vibration of the spring vibrating feeder 211 causes the springs to be fed in sequence along the spring conveying track 212. The spring assembly device 210 clamps the springs on the spring conveying track 212 and inserts them into the cavity of the ink bag.

[0026] For example, the spring assembly device 210 includes a transfer gripper 213, a first assembly gripper 216, and a telescopic cylinder 215. The transfer gripper 213 is located at the end of the spring transport track 212. The transfer gripper 213 can hold the spring transported by the spring transport track 212 and transfer it to the first assembly gripper 216. The first assembly gripper 216 is connected to the telescopic cylinder 215. The telescopic cylinder 215 drives the first assembly gripper 216 to install the spring into the cavity of the ink bag. The vibration of the spring vibrating tray 211 causes the spring to be transported in a flat state along the spring conveying track 212. The transfer gripper 213 is located at the end of the spring conveying track 212. After gripping the spring at the end of the spring conveying track 212, it rotates 90 degrees to adjust its posture so that the first assembly gripper 216 can grip the spring in a vertical posture from the transfer gripper 213. The first assembly gripper 216 is connected to the telescopic cylinder 215. After the first assembly gripper 216 grips the spring, it is driven by the telescopic cylinder 215 to put the spring into the cavity of the ink bag in a vertical posture.

[0027] For example, the spring assembly device 210 also includes a first moving track 214, and a telescopic cylinder 215 is slidably disposed on the first moving track 214. The telescopic cylinder 215 slides along the first moving track 214 to move the first assembly gripper 216 above the ink bag. The first moving track 214 extends from the end of the spring conveying track 212 to the top of the ink bag assembly station. After the transfer gripper 213 transfers the spring from the end of the conveying track to the first assembly gripper 216, the telescopic cylinder 215 slides along the first moving track 214 to move the first assembly gripper 216 together with the spring to the top of the ink bag assembly station. Then the telescopic cylinder 215 extends downward to drive the first assembly gripper 216 to precisely press the spring into the ink bag cavity in a vertical position. After it is in place, the gripper releases and resets, completing a single spring assembly action. Subsequently, the first assembly gripper 216 returns to the end of the spring conveying track 212 along the first moving track 214 with the telescopic cylinder 215, waiting for the handover of the next transfer gripper 213. This cycle repeats to achieve continuous automated assembly of the spring.

[0028] like Figure 5As shown, the spring steel ball assembly mechanism 200 includes a steel ball assembly device 220, which includes a steel ball hopper 221 and an air-blowing conveying device 223. The steel ball hopper 221 sorts and arranges the steel balls so that they are output one by one through the outlet of the steel ball hopper 221. The air-blowing conveying device 223 conveys the steel balls output from the steel ball hopper 221 to the outlet of the steel ball assembly mechanism through air blowing. The outlet of the steel ball assembly mechanism is aligned with the opening of the ink bag. The air-blowing conveying device 223 presses the steel balls into the cavity of the ink bag through airflow. The steel ball hopper 221 sorts and arranges the steel balls so that they are output one by one through the outlet of the steel ball hopper 221. The steel ball hopper 221 is also equipped with an electric material handling mechanism 222. The electric material handling mechanism 222 sorts and arranges the steel balls by rotation or vibration to ensure that the steel balls are arranged in an orderly manner and enter the outlet one by one, avoiding the accumulation or jamming of steel balls. The air blowing and conveying device 223 includes a carrier air interface, a conveying pipeline, and an air blowing and pushing mechanism. The carrier air interface is connected to a compressed air source. The conveying pipeline connects the carrier air interface to the output port of the steel ball assembly mechanism. The air blowing and pushing mechanism is set in the conveying pipeline. By controlling the on / off state and pressure of the compressed air flow, the steel ball is stably pushed along the conveying pipeline to the output port, and the steel ball is pressed into the ink bag cavity with a set pressure to complete the steel ball assembly.

[0029] The spring steel ball assembly mechanism 200 is connected to a lifting device 224. The lifting device 224 is driven by a cylinder. The lifting device 224 drives the spring steel ball assembly mechanism 200 to lift as a whole, so that the output port of the steel ball assembly mechanism can extend to the opening of the ink bag, thereby using airflow to accurately press the steel ball into the ink bag cavity.

[0030] For example, the spring ball assembly mechanism 200 also includes an installation detection device 230, which is distributed along the transfer device 100 at the rear end of the ball assembly device 220. The installation detection device 230 is equipped with a sensor, which is aligned with the opening of the ink bag cavity to detect whether the ball has been pressed into place. When the ball passes through the sensor detection area, the sensor outputs a corresponding detection signal. The control system determines whether the ball has been correctly pressed into the cavity based on the signal. The installation detection device 230 can detect whether the ball and spring are installed in place and identify defects such as missing or incomplete installation.

[0031] like Figure 6As shown, the sealing ring assembly mechanism 300 includes a sealing ring vibratory plate 320, a clamping and pressing device 340, and a second moving track 330. The second moving track 330 is provided above the output end of the sealing ring vibratory plate 320. The clamping and pressing device 340 is slidably disposed on the second moving track 330. The clamping and pressing device 340 can clamp the sealing ring on the sealing ring vibratory plate 320 and move along the second moving track 330 to the top of the ink bag for sealing ring pressing. The sealing ring vibratory feeder 320 automatically sorts and feeds the sealing rings by vibration, continuously supplying parts to the clamping and pressing device 340. After the clamping and pressing device 340 clamps the sealing ring from the conveying track of the sealing ring vibratory feeder 320, it moves along the second moving track 330 to above the ink bag assembly position. The pressing cylinder 342 presses the sealing ring into the corresponding slot of the ink bag. After the sealing ring is pressed, the rear end of the sealing ring assembly mechanism 300 is also equipped with a sealing ring in-place detection device 310. This detection device is equipped with a photoelectric sensor to detect whether the sealing ring has been pressed into place.

[0032] For example, the clamping and pressing device 340 is equipped with a second assembly gripper 341 and a pressing cylinder 342. The second assembly gripper 341 can grip the sealing ring, and the pressing cylinder 342 is located above the second assembly gripper 341. The movable end of the pressing cylinder 342 can extend downward to press the sealing ring on the second assembly gripper 341 into the corresponding slot of the ink bag. The second assembly gripper 341 is an actuating gripper. The gripper end of the second assembly gripper 341 is provided with a contoured groove that matches the shape of the sealing ring. When the gripper is closed, it can stably cover the outer edge of the sealing ring to prevent displacement or detachment during the pressing process. When the movable end of the pressing cylinder 342 extends downward, the second assembly gripper 341 opens simultaneously, so that the sealing ring falls smoothly into the ink bag slot along the axial direction under the thrust of the cylinder, completing the pressing.

[0033] For example, the quantitative ink storage device 500 is equipped with two sets of ink volume control mechanisms 520 that can operate alternately. Each ink volume control mechanism 520 is equipped with a servo motor 530 and a liquid level relay. The ink volume control mechanism 520 controls the ink filling volume through the servo motor 530 and the liquid level relay. The two sets of ink volume control mechanisms 520 operate alternately to achieve uninterrupted continuous ink filling. Each ink volume control mechanism 520 uses a 300cc metering cylinder, which, in conjunction with the liquid level relay, achieves precise liquid level control. The servo motor 530 drives the metering structure to switch the ink filling parameters for different types of ink bags, further improving the accuracy of ink filling weight control. Specifically, a control rail 540 is vertically installed on the quantitative ink storage device 500, and the metering structure is a metering limit plate 550. The metering limit plate 550 is slidably installed on the control rail 540. The servo motor 530 drives the metering limit plate 550 to move up and down along the control rail 540 through a lead screw to adjust the piston stroke in the metering cylinder, thereby accurately controlling the ink volume of each filling. The liquid level relay monitors the ink level in the metering cylinder in real time. When the liquid level reaches the set value, the liquid level relay sends a signal, and the control mechanism stops replenishing ink to ensure the consistency of the ink volume each time. When the two sets of ink volume control mechanisms 520 operate alternately, one set of mechanisms is in the ink filling state, and the other set of mechanisms simultaneously performs ink replenishment and metering reset. The two sets of mechanisms achieve seamless connection through timing control.

[0034] The metering ink storage device 500 is also provided with an ink tank placement area 700 on the side, which is used to store ink tanks to replenish the metering ink storage device 500 at any time.

[0035] For example, the clamping and positioning carrier 110 is provided with positioning pins for positioning the ink bag. The positioning pins accurately position the outer ring of the ink bag, and the clamping and positioning carrier 110 clamps the outer ring of the ink bag with a clamping cylinder to ensure that the product position does not shift when the ink bag is processed along each station of the transfer device 100.

[0036] The advantages of implementing the ink bag production equipment provided by this utility model compared with the prior art are as follows: The transfer device 100 of this utility model is a rotary table structure. By setting a clamping and positioning carrier 110 to clamp the ink bag, the assembly, testing, ink filling, and sealing processes of the ink bag are all completed on the ink bag production equipment of this technical solution. This avoids the problems of dispersed processes, long material turnover paths, and repetitive positioning. The spring and steel ball assembly mechanism 200 is distributed along the transfer device 100. The spring and steel ball assembly mechanism 200 can assemble the spring and steel ball into the cavity of the ink bag and perform assembly testing. The sealing ring assembly mechanism 300 is distributed at the rear end of the spring and steel ball assembly mechanism 200 along the transfer device 100. The sealing ring assembly mechanism 300 can press the sealing ring into the corresponding slot of the ink bag, automatically assembling the spring, steel ball, and sealing ring. The assembly consistency is high, and the assembly testing avoids misassembly and omissions, resulting in a stable yield. The quantitative ink filling mechanism includes an ink filling device 400 and a quantitative ink storage device 500. The ink is connected to the transfer device 100 via a quantitative ink storage device 500, which delivers ink to the ink filling device 400. The ink filling device 400, through several ink filling connectors 410 aligned with the openings of the ink bags, can simultaneously fill multiple ink bags, improving filling efficiency. The quantitative ink storage device 500 plays a quantitative control role in the ink delivery, ensuring that a fixed amount of ink is filled into the ink bags. An ink recovery tank 510 is also connected between the quantitative ink storage device 500 and the ink filling device 400. Ink overflowing during the filling process can flow into the ink recovery tank 510 for recovery through the bypass branch pipe, avoiding the problems of uneven filling and ink overflow and waste. The sealing film mechanism 600 is located at the end of the transfer device 100. After filling, the ink bags are sealed by heat-pressing with a sealing film. This technical solution enables the assembly, testing, filling and sealing processes of ink bags to be completed on the ink bag production equipment, avoiding the problems of dispersed processes, long material turnover paths and repetitive positioning.

[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
