Description

Technical Field

[0001] This invention relates to the technical field of printing presses, and in particular to an ink supply device for a printing press. Background Technology

[0002] A printing press is a machine for printing text and images. The purpose of the ink supply device of a printing press is to add ink to the press, ensuring sufficient ink supply and thus guaranteeing the normal and stable operation of the printing press. Existing technology publication number CN216069236U discloses an ink supply device for a printing press, including an L-shaped mounting plate, an ink supply assembly, and a stirring assembly. A fixed top plate is fixedly installed on one side of the L-shaped mounting plate, and an ink supply box and an ink storage box are fixedly installed on the top of the L-shaped mounting plate.

[0003] However, adding ink requires manual handling of the ink container, which is too labor-intensive, prone to dripping, resulting in ink waste, affecting the working environment, and the upper layer of ink is easily oxidized, affecting printing quality. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides an ink supply device for a printing press that can reduce the labor intensity of workers when carrying ink canisters for adding ink, improve work efficiency, prevent unused ink in the upper part from oxidizing and affecting printing quality, and improve the continuity of ink supply.

[0005] This invention discloses an ink supply device for a printing press, comprising a base, a detection box, an ink bucket, an ink pump, a vertical plate, a moving mechanism, a fixing mechanism, a pushing mechanism, an application assembly, a connecting mechanism, and a guiding assembly. Multiple fixing feet are respectively provided at the four corners of the base's bottom. The ink bucket is placed on the moving mechanism via the fixing mechanism. A positioning slot is provided on the base, and the moving mechanism is inserted into the positioning slot. The vertical plate is fixedly installed on the top left end of the base. The pushing mechanism is installed inside the vertical plate, and a guiding assembly is installed on the pushing mechanism. An inflation assembly is installed on the pushing mechanism. The application assembly is installed on the vertical plate. The detection box is installed on the right side wall of the vertical plate. The output end of the ink bucket is connected to the input end of the detection box via the connecting mechanism. An ink pump is installed on the top of the detection box, and the input end of the ink pump is connected to the output end of the detection box. The ink bucket is placed... The ink canister is clamped and secured by a fixing mechanism on the moving mechanism to ensure stability during movement. This moving mechanism reduces the labor intensity of workers when handling ink canisters for refilling, improving work efficiency. After the moving mechanism inserts the ink canister into the positioning slot, it connects to the input end of the testing box via a connecting mechanism. Ink is drawn in by an ink pump and enters the testing box for comparative testing to ensure printing quality. Then, the moving mechanism moves to the top of the ink canister to seal it. Before sealing, erucic acid amide is applied using a coating component to prevent ink adhesion. Simultaneously, nitrogen gas is introduced into the ink canister, forming a nitrogen layer on top to prevent oxidation of unused ink, which would affect printing quality. This also creates positive pressure inside the ink canister, improving the continuity of ink supply.

[0006] Preferably, the moving mechanism includes a movable base, multiple movable wheels, two plug-in positioning slide rails, a push frame, two suction plates, and two electromagnets. Multiple movable wheels are installed at the four corners of the bottom of the movable base. Plug-in positioning slide rails are installed at both the front and rear ends of the movable base. Limit slots are provided at both the front and rear ends of the positioning socket of the base. A suction plate is installed at the left end of the plug-in positioning slide rail. Electromagnets are installed on the front and rear sides of the left end of the base. A push frame is installed on the left side wall of the movable base, and a pull handle is provided on the upper part of the push frame. After the ink bucket is placed on top of the movable base, the push frame and movable base are pulled by pulling the handle. The movable base moves via the multiple movable wheels, driving the ink bucket to move, reducing the labor intensity of workers during handling and improving work efficiency. The movable base enters the positioning socket, causing the plug-in positioning slide rails to insert into the limit slots. At the same time, the suction plates contact the electromagnets, limiting the movement of the movable base and ensuring stability during use.

[0007] Preferably, the fixing mechanism includes two threaded rods, two sliding blocks, two arc-shaped positioning clamps, a rotating rod, and a gearbox. The top of the movable seat has a clamping groove, and a positioning push plate is located at the left end of the top of the movable seat. The two threaded rods are symmetrically and rotatably installed in the clamping groove. A bevel gear is located at the end of the two threaded rods that is close to each other. A rotating groove is located on the left side of the movable seat, and the rotating rod is rotatably installed in the rotating groove. A driving bevel gear is located at the right end of the rotating rod, meshing with the bevel gear. The left input end of the rotating rod is connected to the output end of the gearbox, and a rotating handwheel is located on the gearbox. Sliding blocks are screwed onto the outer wall of the threaded rods, and arc-shaped positioning clamps are installed on the top of the sliding blocks through the clamping groove. After the ink bucket is placed on top of the movable seat, rotating the handwheel drives the gearbox to rotate the rotating rod, which in turn drives the threaded rod to rotate. The threaded rod causes the sliding blocks to move within the clamping groove, and the sliding blocks cause the arc-shaped positioning clamps to move on top of the movable seat, thus clamping and positioning the bottom of the ink bucket with the two arc-shaped positioning clamps, ensuring stability during use and movement.

[0008] Preferably, the testing box includes a transparent tube, a photosensitive chip, and a light source. The transparent tube is installed inside the testing box, the photosensitive chip is installed at the upper part of the testing box, and the light source is installed at the lower part of the testing box. A controller is set at the front end of the upright plate, and the photosensitive chip is connected to the controller. After the ink tank is replaced, the ink is output from the ink tank and enters the transparent tube. The light source is activated to emit light, and the photosensitive chip identifies the ink color and compares the colors of the two ink tanks to avoid large color differences that may affect printing.

[0009] Preferably, the connecting mechanism includes a push-button switch, an output pipe, a connector, an input pipe, a sealing gasket, multiple electric telescopic rods, and multiple clamps. The bottom of the ink tank is tapered, and a discharge pipe is provided at the bottom of the ink tank. The output end of the discharge pipe is connected to an output pipe. An input pipe is installed at the input end of the transparent pipe. The input pipe is installed inside the upright plate. A connector is installed at the output end of the output pipe. An insert sleeve is provided at the input end of the input pipe. A sealing gasket is installed inside the insert sleeve. Multiple electric telescopic rods are axially and evenly installed on the insert sleeve. Clamps are installed at the telescopic ends of the electric telescopic rods. The device is equipped with a connecting groove that matches the clamp. The push-button switch is installed on the side wall of the base and is electrically connected to the electromagnet and the electric telescopic rod. When the ink tank is moved to the use position, the ink tank drives the output pipe and the plug to insert into the insert sleeve. Multiple electric telescopic rods drive the clamps to move closer to each other, so that the clamps enter the connecting groove and connect the plug and the insert sleeve. The sealing gasket increases the sealing after the connection. After the ink in the ink tank is used up, the operator presses the push-button switch with his foot to de-energize the electromagnet and retract the electric telescopic rod, making it easy to move the ink tank away.

[0010] Preferably, the pushing mechanism includes an air pump, a stud, a servo motor, a lifting seat, two guide slides, two guide sliders, a push arm, a push column, and a piston push plate. The interior of the upright plate has a lifting groove. The stud is rotatably installed within the lifting groove. The top input end of the stud is connected to the output end of the servo motor. The middle of the lifting seat is screwed onto the outer wall of the stud. Guide grooves are provided at both the front and rear ends of the lifting groove. Guide slides are installed within the guide grooves. Guide sliders are slidably installed on the outer wall of the guide slides. The two guide sliders are connected to the front and rear ends of the lifting seat. A push arm is fixedly installed at the top left end of the lifting seat. A push column is installed at the top of the push arm. A piston push plate is installed at the bottom of the push column. An air intake channel is provided in the middle of the push column and the piston push plate. The air pump is installed... At the top of the push arm, an air inlet pipe is installed at the input end of the air pump, and the output end of the air pump is connected to the air inlet channel. A rubber sleeve is installed on the outer wall of the piston push plate. The servo motor is started to drive the stud to rotate, and the stud drives the lifting seat to move in the lifting slide. The lifting seat drives the push arm to move, and the push arm drives the push column and piston push plate to move to the upper part of the ink tank, sealing the upper part of the ink tank. This facilitates the discharge of ink from the ink tank and improves the continuity of ink supply. At the same time, the air pump is started to input nitrogen into the ink tank, so that a nitrogen layer is formed on the upper part of the ink tank, preventing the unused ink on the upper part of the ink tank from oxidizing and affecting the printing quality. When the lifting seat moves, it drives the guide slider to slide on the guide slide rod, supporting and guiding the lifting seat to ensure stability during use.

[0011] Preferably, the application assembly includes a circular ring, a rotating ring, two drive gears, two drive sprockets, two tension guide wheels, a transmission belt, and a drive motor. The right end of the circular ring is fixedly mounted on the upper left side wall of the upright plate via a support arm. An annular groove is formed inside the circular ring, and the rotating ring is rotatably mounted in the annular groove. Clearance grooves are formed at the right ends of both the circular ring and the rotating ring. Multiple application blocks are provided on the inner wall of the rotating ring. A replenishment box is provided at the top of the circular ring. Drive boxes are provided at the front and rear ends of the left side of the circular ring, and two drive gears are rotatably mounted in the drive boxes. Teeth are provided on the outer wall of the rotating ring, and the drive gears mesh with the teeth. A drive sprocket is installed at the top input end of the drive gear. Two drive sprockets are rotatably mounted at the top left end of the circular ring. A tension guide wheel and two drive sprockets are connected by a transmission belt. The tension guide wheel guides and supports the transmission belt. The input end of the front drive gear is connected to the output end of the drive motor. After the piston push plate moves downward into the ring, the drive motor is started to drive the drive gear to rotate. The drive gear drives the rotating ring to rotate in the annular groove through its teeth. Erucamide is applied to the rubber sleeve on the outer wall of the piston push plate by an applicator to prevent ink from adhering to the rubber sleeve. The two drive gears rotate synchronously through the cooperation of the transmission belt and the drive sprocket, driving the rotating ring. After the application is completed, the rotating ring and the ring's clearance groove are aligned, allowing the push arm to pass through without obstruction.

[0012] Preferably, the guide assembly includes two support plates, multiple support frames, multiple damping rods, multiple clamping frames, and multiple clamping springs. The two support plates are fixedly installed at the left and right ends of the lifting seat. Support frames are installed at the four corners of the side wall of the end where the two support plates are close to each other. Guide wheels are rotatably installed on the support frames. Multiple damping rods are installed on the left side wall of the left support plate. Clamping frames are installed on the damping rods. Contact wheels are rotatably installed on the clamping frames. The clamping springs are fitted onto the outer wall of the damping rods. One end of the clamping spring is connected to the left support plate, and the other end of the clamping spring is connected to the clamping frame. When the lifting seat moves up and down, the support plates drive the support frames to move, causing the guide wheels to slide on the outer walls of the left and right sides of the vertical plate, providing guidance and support for the lifting seat and improving stability. At the same time, the left support plate drives the contact wheels to contact the outer wall of the ink barrel and cooperate with the positioning and pushing plate, further improving stability.

[0013] Preferably, it also includes a fixed plate, a switch valve body, a valve plate, and a push rod. The switch valve body is installed at the input end of the input pipe. The valve plate is slidably installed inside the switch valve body. A tensioning spring is installed on the top of the valve plate. The fixed plate is fixedly installed on the left side wall of the upright plate. The tensioning spring is slidably installed on the fixed plate. A push plate is provided above the tensioning spring. A push rod that cooperates with the push plate is provided at the bottom left side of the lifting seat. A spring is fitted outside the tensioning spring, and a magnetic plate is provided at the top of the tensioning spring. An electromagnet is provided on the outer wall of the upright plate above the fixed plate. The electromagnet and... The push switch is electrically connected; when the ink runs out, the lifting seat moves down to the bottom, driving the push rod to press down the push plate. The push plate drives the top spring to slide on the fixed plate, pushing the valve plate to be fully inserted into the switch valve body. At the same time, the magnetic plate is attracted to the electromagnet, fixing the top spring, thereby sealing the input end of the input tube, maintaining pressure in the delivery pipeline, preventing air from entering, and facilitating uninterrupted ink delivery. After the ink tank is replaced, the electromagnet releases the attraction between itself and the magnetic plate, and the spring pushes the top spring upward, allowing the ink to continue to be delivered.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The ink bucket is placed on the moving mechanism, and the ink bucket is clamped and fixed by the fixing mechanism to ensure stability during movement. The moving mechanism can reduce the labor intensity of workers when carrying ink buckets for addition and improve work efficiency. After the moving mechanism drives the ink bucket to be inserted into the positioning socket, the ink bucket is connected to the input end of the detection box through the connecting mechanism. The ink is drawn by the ink pump and enters the detection box for comparative testing to ensure printing quality. Then, the pushing mechanism moves to the top of the ink bucket to seal its upper part. Before sealing, erucamide is applied to it by the coating component to prevent ink adhesion. At the same time, nitrogen gas is introduced into the ink bucket to form a nitrogen layer on the upper part of the ink bucket, preventing the unused ink on the upper part of the ink bucket from oxidizing and affecting the printing quality. At the same time, the inside of the ink bucket is kept under positive pressure to improve the continuity of ink supply. Attached Figure Description

[0026] Example 1

[0027] like Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, multiple fixed feet are provided at the four corners of the bottom of the base 1.

Inside the detection box 2, the photosensitive chip 7 is installed at the upper part, and the light source 9 is installed at the lower part. A controller is set at the front end of the upright plate 28, and the photosensitive chip 7 is connected to the controller. The bottom of the ink tank 13 is tapered, and a discharge pipe is set at the bottom of the ink tank 13. The output end of the discharge pipe is connected to the output pipe 15. An input pipe 17 is installed at the input end of the transparent pipe 6. The input pipe 17 is installed inside the upright plate 28. A connector 16 is installed at the output end of the output pipe 15. An insert sleeve is set at the input end of the input pipe 17. A sealing gasket 18 is installed inside the insert sleeve. Multiple electric telescopic rods 19 are axially and evenly installed on the insert sleeve. A clamp 20 is installed at the telescopic end of the electric telescopic rod 19. A matching clamp 20 is set on the connector 16. A connecting slot is provided. A push switch 12 is installed on the side wall of the base 1. The push switch 12 is electrically connected to the electromagnet 11 and the electric telescopic rod 19. A lifting slide groove is provided inside the upright plate 28. A stud 29 is rotatably installed in the lifting slide groove. The top input end of the stud 29 is connected to the output end of the servo motor 30. The middle part of the lifting seat 31 is screwed onto the outer wall of the stud 29. Guide slide grooves are provided at both the front and rear ends inside the lifting slide groove. A guide slide rod 32 is installed in the guide slide groove. A guide slider 33 is slidably installed on the outer wall of the guide slide rod 32. The two guide sliders 33 are connected to the front and rear ends of the lifting seat 31. A push arm 36 is fixedly installed at the top left end of the lifting seat 31. A push column 37 is installed at the top of the push arm 36. A piston push plate 38 is installed at the bottom of the push column 37. An air intake channel is provided in the middle of the push column 37 and the piston push plate 38. The air pump 27 is installed on the top of the push arm 36. An air intake pipe is provided at the input end of the air pump 27, and the output end of the air pump 27 is connected to the air intake channel. A rubber sleeve is provided on the outer wall of the piston push plate 38. The switch valve body 50 is installed at the input end of the input pipe 17. The valve plate 51 is slidably installed inside the switch valve body 50. A clamping spring 48 is installed on the top of the valve plate 51. The fixing plate 49 is fixedly installed on the left side wall of the upright plate 28. The clamping spring 48 is slidably installed on the fixing plate 49. A push plate is provided on the upper part of the clamping spring 48. A push rod 52 that cooperates with the push plate is provided on the bottom left side of the lifting seat 31. A spring is sleeved on the outside of the clamping spring 48, and a magnetic suction plate is provided on the top of the clamping spring 48.An electromagnet 11 is installed on the outer wall of the upright plate 28 above the fixed plate 49, and the electromagnet 11 is electrically connected to the push switch 12;

[0028] After placing the ink bucket 13 on top of the movable base 3, pull the handle to move the push frame 8 and the movable base 3. The movable base 3 moves via multiple casters 4, which in turn moves the ink bucket 13, reducing the labor intensity of workers during handling and improving work efficiency. The movable base 3 enters the positioning socket, causing the insertion positioning slide rail 5 to insert into the limit slot. At the same time, the adsorption plate 10 contacts the electromagnet 11 to limit the movable base 3, ensuring stability during use. When the ink bucket 13 moves to the usage position, it causes the output pipe 15 and the connector 16 to insert into the insertion sleeve. Multiple electric telescopic rods 19 drive the clamps 20 to interact. Approaching the machine, clamp 20 is inserted into the connecting groove, connecting connector 16 and insert sleeve. Sealing gasket 18 enhances the seal after connection. After the ink in ink tank 13 is used up, the operator presses switch 12 with their foot to de-energize electromagnet 11, simultaneously retracting electric telescopic rod 19 to facilitate removal of ink tank 13. After replacing ink tank 13, ink is output from ink tank 13 and enters transparent tube 6. Light source 9 is activated to emit light, and photosensitive chip 7 identifies the ink color, comparing the colors of the two ink tanks to avoid significant color differences affecting printing. Servo motor 30 is activated to drive stud 2. 9. Rotation causes the stud 29 to move the lifting seat 31 within the lifting slide groove. The lifting seat 31 then moves the push arm 36, which in turn moves the push column 37 and piston push plate 38 to the upper part of the ink tank 13, sealing the upper part of the ink tank 13. This facilitates the discharge of ink from the ink tank 13, improving ink supply continuity. Simultaneously, the air pump 27 is activated to inject nitrogen into the ink tank 13, forming a nitrogen layer on the upper part of the ink tank 13. This prevents unused ink in the upper part of the ink tank 13 from oxidizing, which would affect printing quality. As the lifting seat 31 moves, it causes the guide slider 33 to slide on the guide rod 32, providing support for the lifting seat 31. The guide ensures stability during use. When the ink is used up, the lifting seat 31 moves down to the bottom, driving the push rod to press down the push plate. The push plate drives the top spring 48 to slide on the fixed plate 49, pushing the valve plate 51 to be fully inserted into the switch valve body 50. At the same time, the magnetic plate is attracted to the electromagnet 11, fixing the top spring 48, thereby sealing the input end of the input pipe 17, maintaining pressure in the conveying pipe, preventing air from entering, and facilitating uninterrupted ink delivery. After replacing the ink tank 13, the electromagnet 11 releases the attraction between itself and the magnetic plate, and the spring pushes the top spring 48 upward, allowing the ink to continue to be delivered.

[0029] Example 2

[0030] like Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, the top of the movable seat 3 has a clamping groove, and a positioning push plate is provided at the top left end of the movable seat 3. Two threaded rods 22 are symmetrically and rotatably installed in the clamping groove. A bevel gear is provided at the end of the two threaded rods 22 that are close to each other. A rotating groove is provided on the left side of the movable seat 3, and a rotating rod 25 is rotatably installed in the rotating groove. A driving bevel gear is provided at the right end of the rotating rod 25, and the driving bevel gear meshes with the bevel gear. The left input end of the rotating rod 25 is connected to the output end of the gearbox 26, and a rotating handwheel is provided on the gearbox 26. A sliding block 23 is screwed onto the outer wall of the threaded rod 22. An arc-shaped positioning clamping plate 24 is installed on the top of the sliding block 23 through a clamping groove. The right end of the ring 39 is fixedly installed on the upper left side wall of the upright plate 28 via a support arm. An annular groove is formed inside the ring 39, and a rotating ring 40 is rotatably installed within the annular groove. Clearance grooves are formed on the right ends of both the ring 39 and the rotating ring 40. Multiple application blocks are provided on the inner wall of the rotating ring 40. A replenishment box is provided on the top of the ring 39. Drive boxes are located at the front and rear ends of the left side of the ring 39. Two drive boxes... The driving gear 41 is rotatably mounted inside the drive housing. Teeth are provided on the outer wall of the rotating ring 40, and the driving gear 41 meshes with these teeth. A drive sprocket 42 is mounted on the top input end of the driving gear 41. Two tension guide wheels 43 are rotatably mounted on the top left end of the ring 39. The two drive sprockets 42 are connected by a transmission belt 44, which guides and supports the transmission belt 44. The input end of the front drive gear 41 is connected to the output end of the drive motor 45. Two support plates 34 are fixedly mounted. At the left and right ends of the lifting seat 31, support frames 35 are installed at the four corners of the side wall of the two support plates 34 that are close to each other. Guide wheels are rotatably installed on the support frames 35. Multiple damping rods 46 are installed on the left side wall of the left support plate 34. A clamping frame 47 is installed on the damping rod 46. A contact wheel is rotatably installed on the clamping frame 47. A clamping spring 48 is fitted on the outer wall of the damping rod 46. One end of the clamping spring 48 is connected to the left support plate 34, and the other end of the clamping spring 48 is connected to the clamping frame 47.

[0031] After the ink container 13 is placed on top of the movable base 3, the handwheel is turned to drive the gearbox 26 to rotate the rotating rod 25. This drives the bevel gear and the threaded rod 22 to rotate. The threaded rod 22 then moves the sliding block 23 within the clamping groove. The sliding block 23 moves the arc-shaped positioning clamp 24 on top of the movable base 3, clamping and positioning the bottom of the ink container 13 to ensure stability during movement and use. After the piston push plate 38 moves downward into the ring 39, the drive motor 45 is started to drive the drive gear 41 to rotate. The drive gear 41 drives the rotating ring 40 to rotate within the annular groove through its teeth. Erucamide is then applied by the application block. The ink is applied to the rubber sleeve on the outer wall of the piston push plate 38 to prevent it from adhering. The transmission belt 44 and the drive sprocket 42 work together to make the two drive gears 41 rotate synchronously, driving the rotating ring 40. After the coating is completed, the rotating ring 40 and the clearance groove of the ring 39 correspond to each other, allowing the push arm 36 to pass through without obstruction. When the lifting seat 31 moves up and down, the support plate 34 drives the support frame 35 to move, so that the guide wheel slides on the outer walls of the left and right sides of the upright plate 28 to guide and support the lifting seat 31 and improve stability. At the same time, the left support plate 34 drives the contact wheel to contact the outer wall of the ink tank 13 and cooperate with the positioning push plate to further improve stability.

[0032] like Figures 1 to 9As shown, the ink supply device for a printing press of the present invention, when in operation, after the ink bucket 13 is placed on top of the movable seat 3, the handwheel drives the gearbox 26 to rotate the rotating rod 25, which in turn drives the bevel gear and the threaded rod 22 to rotate. The threaded rod 22 drives the sliding block 23 to move in the clamping groove. The sliding block 23 drives the arc-shaped positioning clamp 24 to move on top of the movable seat 3, so that the two arc-shaped positioning clamps 24 clamp and position the bottom of the ink bucket 13. By pulling the handle, the push frame 8 and the movable seat 3 are pulled. The movable seat 3 moves through multiple moving wheels 4, which moves the ink bucket 13, reducing the labor intensity of the workers when handling it and improving work efficiency. The movable seat 3 enters the positioning socket, which drives the insertion positioning slide rail 5 to insert into the limiting slot. Simultaneously, the adsorption plate 10 contacts the electromagnet 11, limiting the movement of the movable seat 3. When the ink tank 13 moves to the usage position, the ink tank 13 drives the output pipe 15 and the connector 16 to insert into the insert sleeve. Multiple electric telescopic rods 19 drive the clamps 20 to move closer to each other, allowing the clamps 20 to enter the connecting groove and connect the connector 16 and the insert sleeve. The sealing gasket 18 increases the sealing after connection. The ink pump 21 draws ink, and the servo motor 30 is started to drive the stud 29 to rotate. The stud 29 drives the lifting seat 31 to move in the lifting slide. The lifting seat 31 drives the push arm 36 to move. The push arm 36 drives the push column 37 and the piston push plate 38 to move to the upper part of the ink tank 13. After the piston push plate 38 moves downward into the ring 39, the start-up is complete. The drive motor 45 drives the drive gear 41 to rotate, and the drive gear 41 drives the rotating ring 40 to rotate in the annular groove through its teeth. Erucamide is applied to the rubber sleeve on the outer wall of the piston push plate 38 using an applicator, preventing ink from adhering to the rubber sleeve. The transmission belt 44 and drive sprocket 42 work together to make the two drive gears 41 rotate synchronously, driving the rotating ring 40. After application, the rotating ring 40 aligns with the clearance groove of the annular ring 39, allowing the push arm 36 to pass through and seal the upper part of the ink tank 13. The air pump 27 is started to input nitrogen into the ink tank 13, forming a nitrogen layer on the upper part of the ink tank 13 to prevent oxidation of unused ink. When the lifting seat 31 moves, it drives the guide slider 33 to slide on the guide rod 32, thus lifting the... The lifting seat 31 provides support and guidance. As the lifting seat 31 moves up and down, it drives the support frame 35 to move via the support plate 34, causing the guide wheels to slide on the left and right outer walls of the upright plate 28, providing guidance and support for the lifting seat 31 and improving stability. Simultaneously, the left support plate 34 drives the contact wheel to contact the outer wall of the ink tank 13. When the ink is used up, the lifting seat 31 moves downwards to its lowest point, driving the push rod to press down the push plate. The push plate drives the top spring 48 to slide on the fixed plate 49, pushing the valve plate 51 to fully insert into the switch valve body 50. At the same time, the magnetic plate attracts the electromagnet 11, fixing the top spring 48, thereby sealing the input end of the input pipe 17, maintaining pressure in the delivery pipe, and preventing air from entering. After the ink in the ink tank 13 is used up...The operator presses the foot switch 12 to de-energize the electromagnet 11, simultaneously retracting the electric telescopic rod 19 to facilitate the removal of the ink container 13. After replacing the ink container 13, the electromagnet 11 releases its attraction from the magnetic plate, and the spring pushes the top spring 48 upward, allowing the ink to continue being delivered. After replacing the ink container 13, the ink exits from the ink container 13 and enters the transparent tube 6. The light source 9 is activated to emit light, and the photosensitive chip 7 identifies the ink color, comparing the colors of the two ink containers to avoid significant color differences.
