Description

Technical Field

[0001] This application relates to the field of ink solvent dispensing technology, and in particular to a feeding device for an ink dispensing system. Background Technology

[0002] An ink dispensing system is an automated device specifically designed for quantitative dispensing of inks, widely used in industries such as printing, coatings, and chemicals. These systems typically possess precise metering capabilities, can handle liquids of varying viscosities, and ensure the safety and efficiency of the dispensing process.

[0003] During the ink production process, workers typically use a ladle to remove the ink from the material bucket and then add the ink to the feeding hopper of the ink solvent dispensing system.

[0004] The existing technical solutions mentioned above have the following drawbacks: most ink solvents are viscous liquids, and the method of manually using a water ladle to hold the ink requires repeated operations, which increases the labor intensity of workers and reduces the efficiency of adding materials. Utility Model Content

[0005] This application provides a feeding device for an ink dispensing system in order to reduce the labor intensity of workers and improve feeding efficiency.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0007] A feeding device for an ink dispensing system includes a base, a cylinder fixedly connected to the base, a piston slidably disposed within the cylinder, an electric push rod mounted on the base, the output end of the electric push rod extending into the cylinder and fixedly connected to the piston, two one-way tubes connected to the cylinder, a fixed frame fixedly connected inside the one-way tube, a guide rod fixedly connected to the fixed frame, a guide tube sleeved on the guide rod, a first elastic element fixedly connected inside the guide tube, one end of the first elastic element fixedly connected to the guide rod, a stop block fixedly connected to one end of the guide rod, one end of the stop block extending out of the one-way tube, an annular groove for the stop block to be embedded in one end of the one-way tube, the end of the one-way tube near the stop block being the output end, and the other end being the input end, the cylinder being connected to the input end and output end of the two one-way tubes respectively, the one-way tube with the input end away from the cylinder being connected to an input tube, and the one-way tube with the output end away from the cylinder being connected to an output tube, a controller mounted on the base, the controller being electrically connected to the electric push rod.

[0008] By adopting the above technical solution, the electric push rod drives the piston to reciprocate within the cylinder. The two one-way pipes on the cylinder open and close sequentially, which can draw ink from the material bucket into the cylinder and then transport it to the ink dispensing system. The frequency and distance of the reciprocating motion of the piston driven by the electric push rod can be adjusted by the controller, which facilitates the adjustment of the feeding speed and the volume of each feeding. This reduces the number of manual operation steps when feeding ink into the ink dispensing system, reduces the labor intensity of workers, reduces ink residue in the feeding device, and improves feeding efficiency.

[0009] Optionally, two cylinders and two electric push rods are provided, with the input pipes on the two cylinders connected to a common feed pipe and the output pipes on the two cylinders connected to a common discharge pipe.

[0010] By adopting the above technical solution, the two electric push rods are controlled to move back and forth alternately, so that the two cylinders alternately input and output ink, and the feeding device continuously inputs ink into the ink dispensing system, thereby improving the feeding efficiency.

[0011] Optionally, one end of the feed pipe is connected to a conveying pipe, a push screw is rotatably installed inside the conveying pipe, one end of the conveying pipe is closed and a motor is installed thereon, the output shaft of the motor is connected to the push screw, and the controller is electrically connected to the motor.

[0012] By adopting the above technical solution, the motor is controlled to rotate when ink is input into the feeding device, so that the push screw pushes the ink in the material tank into the feeding pipe, reducing the resistance when the feeding device inputs ink, which is beneficial to the feeding device input of ink and improves the feeding efficiency.

[0013] Optionally, the piston is provided with a first sealing ring on its peripheral wall, and a scraper ring is fixedly connected to the first sealing ring.

[0014] By adopting the above technical solution, a scraper ring is set on the first sealing ring, so that the scraper ring moves back and forth with the piston in the cylinder to scrape off the ink adhering to the inner wall of the cylinder, reduce ink residue in the cylinder, reduce ink residue in the feeding device, improve feeding efficiency, facilitate the reciprocating movement of the piston in the cylinder, and facilitate the measurement of the volume of material fed by the feeding device each time.

[0015] Optionally, a second sealing ring is provided on the stop block.

[0016] By adopting the above technical solution, a second sealing ring is set on the baffle to increase the sealing performance at the connection between the baffle and the one-way pipe, thus ensuring the reliability and stability of the feeding device.

[0017] Optionally, an extrusion pad is fixed to the piston, and at least two extrusion pads are spaced apart.

[0018] By adopting the above technical solution, the connection between the extrusion pad and the cylinder body and the one-way tube is reduced, ink residue in the cylinder body is reduced, the risk of ink adhesion leading to reduced sealing of the one-way tube is reduced, and the stability and safety of the feeding device are ensured.

[0019] Optionally, a fixed flange ring is fixedly connected to the cylinder body, and two fixed flange rings are provided. Both ends of the one-way pipe are fixedly connected to a connecting flange ring of the two one-way pipes, and the two fixed flange rings are respectively connected to one of the connecting flange rings of the two one-way pipes.

[0020] By adopting the above technical solution, the connecting flange ring connects the one-way pipe to the cylinder body, which facilitates the disassembly and maintenance of the one-way pipe, makes it easy to clean the one-way pipe, and ensures the stability and safety of the feeding device.

[0021] Optionally, the base is equipped with casters at its bottom, and at least two casters are provided.

[0022] By adopting the above technical solution, universal wheels are installed at the bottom of the base, which facilitates the movement of the feeding device in the production workshop, improves the mobility and ease of operation of the feeding device, and enhances the applicability of the feeding device to different production layouts and work requirements.

[0023] In summary, this application has the following technical effects:

[0024] 1. By setting up a cylinder, electric push rod, piston, one-way tube and controller, the ink in the material tank can be sucked into the cylinder and then transported to the ink dispensing system. The controller adjusts the frequency and distance of the reciprocating motion of the piston driven by the electric push rod, which facilitates the adjustment of the feeding speed and the volume of each feeding, reduces the manual operation steps when feeding into the ink dispensing system, reduces the labor intensity of workers, reduces ink residue in the feeding device and improves feeding efficiency;

[0025] 2. By setting up a feeding pipe, a push screw and a motor, the motor is controlled to rotate when ink is input into the feeding device, so that the push screw pushes the ink in the material tank into the feeding pipe, reducing the resistance when the feeding device inputs ink, which is conducive to the input of ink into the feeding device and improving the feeding efficiency;

[0026] 3. By setting an extrusion pad, the extrusion pad squeezes the connection between the cylinder and the one-way tube, reducing ink residue in the cylinder and lowering the risk of reduced sealing of the one-way tube due to ink adhesion, thus ensuring the stability and safety of the feeding device.

[0032] The present application will be further described in detail below with reference to the accompanying drawings.

[0033] This application discloses a feeding device for an ink dispensing system, referring to... Figure 1 and Figure 2 The feeding device includes a base 1, with four casters 13 installed at the bottom of the base 1 in a rectangular arrangement. In this embodiment, the casters 13 are self-locking casters. A mounting bracket 11 is bolted to the base 1, and a cylinder 2 is bolted to the mounting bracket 11. Two cylinders 2 are spaced apart and are vertically arranged. A piston 3 is slidably arranged inside the cylinder 2. A first sealing ring 31 is embedded in the peripheral wall of the piston 3. A scraper ring 32 is integrally formed on the outer wall of the first sealing ring 31. Both the first sealing ring 31 and the scraper ring 32 slide along the inner wall of the cylinder 2. An electric push rod 12 is installed on the base 1. Two electric push rods 12 are spaced apart and are located below the two cylinders 2 respectively. The output end of the electric push rod 12 extends into the cylinder 2 and is bolted to the piston 3.

[0034] Reference Figure 2 and Figure 3A fixed flange ring 21 is welded to the top of the cylinder body 2. Two fixed flange rings 21 are spaced apart. A one-way pipe 4 is connected to the fixed flange ring 21. Both ends of the one-way pipe 4 are welded with connecting flange rings 41. The connecting flange rings 41 are fixed to the fixed flange ring 21 by bolts. A fixing frame 42 is welded inside the one-way pipe 4. A guide rod 43 is integrally formed on one side of the fixing frame 42. The guide rod 43 is arranged along the length of the one-way pipe 4. A guide tube 44 is sleeved on the section of the guide rod 43 away from the fixing frame 42. An elastic element 45 is welded inside the guide tube 44. In this embodiment, the elastic element 45 is a spring. One end of the elastic element 45 is welded to the end of the guide tube 44 away from the guide rod 43. The other end of the elastic element 45... One end is welded to the guide rod 43 near the guide tube 44. A stop block 46 is welded to the end of the guide tube 44 away from the fixed frame 42. The stop block 46 is slidably disposed in the one-way tube 4. The stop block 46 is conical and its tip is connected to the guide tube 44. The end of the stop block 46 away from the guide tube 44 extends out of the one-way tube 4. An annular groove 47 for the stop block 46 to be embedded is opened at the end of the one-way tube 4 near the stop block 46. A second sealing ring 461 is embedded in the section of the stop block 46 away from the guide rod 43. The outer wall of the second sealing ring 461 abuts against the inner wall of the annular groove 47. The end of the one-way tube 4 near the stop block 46 is the output end and the other end is the input end. The cylinder body 2 is connected to the input end and the output end of the two one-way tubes 4 respectively.

[0035] Reference Figure 1 and Figure 2 An extrusion pad 33 is attached to the piston 3. In this embodiment, the extrusion pad 33 is made of silicone rubber. Two extrusion pads 33 are spaced apart. The two extrusion pads 33 can respectively abut against one end of two one-way tubes 4. The one-way tube 4 with the input end away from the cylinder 2 is connected to the input tube 5. One end of the two input tubes 5 is connected to the feed tube 6. The one-way tube 4 with the output end away from the cylinder 2 is connected to the output tube 7. One end of the two output tubes 7 is connected to the discharge tube 8. In this embodiment, the feed tube 6 and the discharge tube 8 are both flexible hoses.

[0036] Reference Figure 1 and Figure 4 The feed pipe 6 is connected to a conveying pipe 9 at the end away from the input pipe 5. A push screw 91 is rotatably installed inside the conveying pipe 9. One end of the conveying pipe 9 is closed and a motor 92 is installed. The output shaft of the motor 92 extends into the conveying pipe 9 and is connected to the push screw 91 through a coupling. A controller is installed on the base 1. A PLC processor is installed inside the controller. The controller is electrically connected to the electric push rod 12 and the motor 92.

[0037] When using this feeding device, the feed pipe 6 is inserted into the material tank. The controller controls the electric push rod 12 to retract, causing the piston 3 to move within the cylinder 2 and generate negative pressure. At this time, the stop block 46 in the one-way pipe 4 connected to the input pipe 5 slides away from the one-way pipe 4, making the one-way pipe 4 connected to the input pipe 5 open. The stop block 46 in the one-way pipe 4 connected to the output pipe 7 moves closer to the one-way pipe 4, closing the one-way pipe 4 connected to the output pipe 7 and drawing ink into the cylinder 2. After the ink is drawn into the cylinder 2, the electric push rod 12 stops moving. The elastic force of the first elastic element 45 pulls the stop block 46 towards the one-way pipe 4, closing both one-way pipes 4. The controller then controls the electric push rod 12 to push the piston 3 within the cylinder 2 to move the oil... When the ink is ejected, the one-way pipe 4 connected to the input pipe 5 closes, and the one-way pipe 4 connected to the output pipe 7 opens, pushing the ink out of the cylinder 2. The ink is then output through the discharge pipe 8 to the feeding hopper of the ink dispensing system. The piston 3 is driven by the electric push rod 12 to move back and forth in the cylinder 2. The two one-way pipes 4 on the cylinder 2 open and close in sequence, which can draw the ink in the material bucket into the cylinder 2 and then transport it to the ink dispensing system. The frequency and distance of the reciprocating motion of the piston 3 driven by the electric push rod 12 can be adjusted by the controller, which facilitates the adjustment of the feeding speed and the volume of each feeding, reduces the manual operation steps when feeding the ink dispensing system, reduces the labor intensity of workers, reduces ink residue in the feeding device, and improves feeding efficiency.

[0038] The controller controls the two electric push rods 12 to move back and forth alternately, so that the two cylinders 2 alternately input and output ink, so that the feeding device continuously inputs ink into the ink dispensing system, thereby improving the feeding efficiency.

[0039] By installing casters 13 at the bottom of the base 1, the feeding device can be moved around in the production workshop, improving the mobility and ease of operation of the feeding device and enhancing its applicability to different production layouts and work requirements.

[0040] By setting a scraper ring 32 on the first sealing ring 31, the scraper ring 32 moves back and forth with the piston 3 in the cylinder 2, scraping off the ink adhering to the inner wall of the cylinder 2, reducing ink residue in the cylinder 2, reducing ink residue in the feeding device, improving feeding efficiency, facilitating the reciprocating movement of the piston 3 in the cylinder 2, and making it easier to measure the volume of each feeding by the feeding device.

[0041] By extruding the connection between the cylinder 2 and the one-way tube 4 through the extrusion pad 33, the ink residue in the cylinder 2 is reduced, the risk of ink adhesion leading to reduced sealing of the one-way tube 4 is reduced, and the stability and safety of the feeding device are ensured.

[0042] The one-way pipe 4 is connected to the cylinder body 2 by connecting flange ring 41, which facilitates the disassembly and maintenance of the one-way pipe 4, and makes it easy to clean the one-way pipe 4, input pipe 5 and output pipe 7, ensuring the stability and safety of the feeding device.

[0043] By setting a second sealing ring 461 on the stop 46, the sealing performance at the connection between the stop 46 and the one-way pipe 4 is increased, ensuring the reliability and stability of the feeding device.

[0044] The controller controls the motor 92 to rotate when the ink is fed into the feeding device, so that the push screw 91 pushes the ink in the material tank into the feed pipe 6, reducing the resistance when the ink is fed into the feeding device, which is beneficial to the ink feeding device and improves the feeding efficiency.

[0045] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
