Description

Technical Field

[0001] This utility model relates to the field of pad printing technology, and in particular to a magnet-embedded oil cup. Background Technology

[0002] Pad printing is a printing technology that transfers ink from a gravure plate to an irregularly shaped surface. It is widely used in many fields such as electronics, automobiles, and daily consumer goods. With the rapid development of digital printing technology, pad printing machines are being used more and more widely in the manufacturing industry, and the performance requirements for the key component of pad printing machines, the ink cup, are also increasing.

[0003] Confirm that the pad printing machine platform is flat and the steel plate is securely installed. Check that the ink cup sealing ring, vent valve, and magnet cover are intact. Select the appropriate ink according to the printing material. Use a magnetic field strength meter to test the magnet's magnetism, ensuring that all magnet poles are aligned. If the magnetism weakens by more than 10%, the magnet assembly needs to be replaced. Place the ink cup above the pad printing steel plate and adjust it manually or with a robotic arm to ensure the distance between the bottom of the ink cup and the steel plate is 0.2mm. Start the pad printing machine for a no-load test and observe whether the ink cup shifts or vibrates. If necessary, fine-tune the magnet position. Insert the scraper into the slot at the bottom of the ink cup and tighten the fixing screws. Open the ink chamber sealing cover and slowly inject ink to 80%-90% of the capacity. After closing the sealing cover, gently tap the outer wall of the ink cup to expel air bubbles from the ink. Open the top vent valve and close it after ink overflows from the vent hole. Start the pad printing machine. The scraper scrapes off excess ink at a speed of 10-20mm / s to evenly cover the etched pattern on the steel plate.

[0004] However, some existing ink cups use an external magnet design, which is prone to falling off during equipment operation. Once fallen off, it will not only cause scratches and collisions to the expensive and precision steel sheet below, resulting in scratches, pits and other defects on the surface of the steel sheet, affecting the accuracy and quality of pad printing, but may also cause equipment failure, increasing maintenance costs and downtime. In addition, the magnets used in the ink cups often do not meet the actual working requirements in terms of magnetic strength, resulting in insufficient adsorption between the ink cup and the steel sheet. During pad printing operations, the ink cup is prone to displacement and shaking, reducing the stability and accuracy of printing. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] This solves the problem of externally mounted magnets easily falling off, preventing magnets from falling off and damaging the steel plate, reducing equipment maintenance costs, reducing the shaking of the ink cup during operation, and improving printing stability and accuracy.

[0007] (II) Technical Solution

[0008] In view of the above-mentioned printing instability problem, this utility model is proposed.

[0009] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a magnet-embedded oil cup, including a body, a cover plate installed at the top of the body, two push plates slidably connected to the top of the body in a mirror-like arrangement, a cavity opened in the inner wall of the body, a magnetic ring snapped into the inner wall of the cavity, a plurality of magnets arranged in a circular array installed on the inner wall of the magnetic ring, a rotating plate slidably connected to the top of the magnets and the top of the magnetic ring, and a doctor blade slidably connected to the bottom of the body, with two connecting posts fixedly connected to the top of the doctor blade in a mirror-like arrangement.

[0010] As a preferred embodiment of the magnet-embedded oil cup of this utility model, the bottom end of the magnetic ring is slidably connected to four evenly distributed blocks that are slidably connected to the outer wall of the doctor blade. The outer wall of the blocks is fixedly connected to a rectangular plate, and the outer wall of the rectangular plate is fixedly connected to two evenly distributed rubber pads that are slidably connected to the inner wall of the machine body.

[0011] As a preferred embodiment of the magnet-embedded oil cup of this utility model, the inner wall of the scraper blade is slidably connected to two guide rods that are mirror-distributed and fixedly connected to the inner wall of the machine body, the inner wall of the connecting column is slidably connected to a limit block, and the outer wall of the limit block is slidably connected to a rectangular block that is fixedly connected to the inner wall of the machine body.

[0012] As a preferred embodiment of the present invention, a magnet-embedded oil cup is provided, wherein: a spring is connected between the inner wall of the rectangular block and the outer wall of the limiting block; a connecting plate that is fixedly connected to the bottom end of the push plate is fixedly connected to the top of the limiting block; and multiple cylindrical seats that are evenly distributed and slidably connected to the inner wall of the rotating plate are fixedly connected to the top of the magnetic ring.

[0013] As a preferred embodiment of the magnet-embedded oil cup of this utility model, the top of the rotating plate is fixedly connected to a handle, the bottom of the rotating plate is fixedly connected to a locking post that engages with the inner wall of the magnetic ring, the outer wall of the locking post is fixedly connected to a plurality of evenly distributed circular protrusions, and the inner wall of the magnetic ring is provided with a circular groove to facilitate the positioning of the circular protrusions.

[0014] As a preferred embodiment of the magnet-embedded oil cup of this utility model, a magnetic block is fixedly connected to the top of the body, a handle is fixedly connected to the top of the cover plate, a magnetic sheet that is slidably connected to the top of the magnetic block is fixedly connected to the bottom of the cover plate, and a sealing ring that is slidably connected to the top of the body is fixedly connected to the bottom of the cover plate.

[0015] The beneficial effects of this utility model are:

[0016] 1. By adding a magnetic ring to enclose the original magnet, a closed magnetic circuit is formed, concentrating the magnetic field lines, reducing magnetic field leakage, avoiding electromagnetic interference to surrounding sensitive equipment such as sensors and electronic components, ensuring system stability, thereby improving the magnet's adsorption efficiency, preventing ink cup shaking, improving printing stability and accuracy, and the magnet is installed on the inner wall of the magnetic ring, avoiding the possibility of the magnet falling off due to external placement, reducing damage to the steel sheet surface, and further improving printing stability.

[0017] 2. The cover is closed by magnetic strips at the bottom of the cover that attract the magnetic blocks of the machine body. Pushing the handle to tilt changes the direction of the force, allowing the user to overcome the magnetic force with a smaller force. When tilted to a certain angle, the leverage effect reduces the required opening force, causing the cover to pop open automatically. This avoids the need to use more tools to disassemble the cover and improves the efficiency of ink injection. At the same time, a sealing ring is provided at the bottom of the cover to prevent oil leakage or the entry of external contaminants. Attached Figure Description

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Example 1

[0028] Reference Figure 1-6 This is the first embodiment of the present invention, providing a magnet-embedded oil cup, including a body 1. A cover plate 2 is installed on the top of the body 1. Two mirror-distributed push plates 3 are slidably connected to the top of the body 1. The top of the push plates 3 has corrugations, and the bottom of the push plates 3 has a slider that slides with the body 1 for easy pushing by the user. A cavity is formed in the inner wall of the body 1, and a magnetic ring 5 is engaged with the inner wall of the cavity. The magnetic ring 5 is a ring structure made of a high magnetic permeability material, such as electrical pure iron, silicon steel sheet, or soft magnetic alloy, used to optimize the magnetic circuit distribution, enhance the magnetic field strength of the target area, and reduce... To minimize magnetic field leakage and improve magnetic energy utilization, the magnetic ring 5 is made of 0.5mm thick silicon steel sheet. Multiple magnets 10 arranged in a circular array are installed on the inner wall of the magnetic ring 5. The magnets 10 are arranged with alternating NS-SN polarities to form a closed magnetic circuit. The magnets 10 are used to attract steel plates. The top of the magnets 10 is slidably connected to the top of the magnetic ring 5 and to a rotating plate 8. The rotating plate 8 is used to prevent the magnets 10 from detaching from the inner wall of the magnetic ring 5. The bottom of the body 1 is slidably connected to a doctor blade 4, which is used to scrape ink. The top of the doctor blade 4 is fixedly connected to two mirror-distributed connecting posts 21.

[0029] The bottom end of the magnetic ring 5 is slidably connected to four evenly distributed blocks 18 that are slidably connected to the outer wall of the doctor blade 4. The outer wall of the blocks 18 is chamfered. A rectangular plate 20 is fixedly connected to the outer wall of the blocks 18. Two evenly distributed rubber pads 19 that are slidably connected to the inner wall of the body 1 are fixedly connected to the outer wall of the rectangular plate 20. The rubber pads 19 are used to push the blocks 18.

[0030] The inner wall of the doctor blade 4 is slidably connected to two guide rods 12 that are mirror-distributed and fixedly connected to the inner wall of the body 1. The inner wall of the connecting column 21 is slidably connected to a limiting block 14. The outer wall of the limiting block 14 is chamfered. The outer wall of the limiting block 14 is slidably connected to a rectangular block 15 that is fixedly connected to the inner wall of the body 1.

[0031] A spring 16 is connected between the inner wall of the rectangular block 15 and the outer wall of the limiting block 14. The spring 16 is used to push the limiting block 14. The top of the limiting block 14 is fixedly connected to a connecting plate 17 which is fixedly connected to the bottom of the push plate 3. The connecting plate 17 is used to drive the limiting block 14 to move. The top of the magnetic ring 5 is fixedly connected to multiple evenly distributed cylindrical seats 11 that are slidably connected to the inner wall of the rotating plate 8.

[0032] During use, the equipment needs to be cleaned and maintained. Pushing the push plate 3 via the connecting plate 17 causes the limiting block 14 to disengage from the connecting column 21. Simultaneously, the limiting block 14 compresses the spring 16. Due to gravity, the doctor blade 4 causes the connecting column 21 to move along the guide rod 12 and disengage from the inner wall of the machine body 1. At the same time, the rubber pad 19, via the rectangular plate 20, causes the stop block 18 to disengage from the limiting position of the magnetic ring 5. Because the outer wall of the magnetic ring 5 has a protruding plate, the magnetic ring 5 causes the protruding plate to disengage along the inner wall of the cavity. After cleaning and installation, the magnetic ring 5 is moved along... The cavity is inserted, and then the doctor blade 4 is aligned with the guide rod 12 and inserted. The outer wall of the doctor blade 4 presses against the stop block 18. The stop block 18 presses against the rubber pad 19 through the rectangular plate 20. The stop block 18 limits the position of the magnetic ring 5. At the same time, the doctor blade 4 drives the connecting post 21 to press against the limiting block 14. Since the outer wall of the limiting block 14 has a chamfer, the limiting block 14 moves along the inner wall of the rectangular block 15 to press against the spring 16. When the connecting post 21 drives the slot to pass through the limiting block 14, the spring 16 releases its elastic force to push the limiting block 14 to engage with the connecting post 21.

[0033] Example 2

[0034] Reference Figure 1-4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a handle is fixedly connected to the top of the rotating plate 8, and a locking post 9 is fixedly connected to the bottom of the rotating plate 8, which engages with the inner wall of the magnetic ring 5. Multiple evenly distributed circular protrusions are fixedly connected to the outer wall of the locking post 9. The protrusions are elastic, and a circular groove is provided on the inner wall of the magnetic ring 5 to facilitate the positioning of the circular protrusions.

[0035] A magnetic block 13 is fixedly connected to the top of the body 1, a handle is fixedly connected to the top of the cover plate 2, a magnetic sheet 6 is fixedly connected to the bottom of the cover plate 2 and is slidably connected to the top of the magnetic block 13, and a sealing ring 7 is fixedly connected to the bottom of the cover plate 2 and is slidably connected to the top of the body 1.

[0036] During use, pulling the handle causes the rotating plate 8 to rotate around the cross-section of the cylindrical base 11 to open. The rotating plate 8 causes the locking pin 9 to disengage from the magnetic ring 5, making it easy to remove the magnet 10 for maintenance. After maintenance, the magnet 10 is placed back in, and the handle is pushed to rotate the rotating plate 8. The rotating plate 8 causes the locking pin 9 to enter the inner wall of the magnetic ring 5. Since the outer wall of the locking pin 9 has elastic protrusions, the locking pin 9 enters the circular groove of the magnetic ring 5 to achieve simple limiting. The handle causes the cover plate 2 to tilt, and the cover plate 2 springs open and disengages from the magnetic block 13, making it easy to inject ink. The operation is now complete.

[0037] The remaining structure is the same as that in Example 1.

[0038] 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.
