Description

Technical Field

[0001] This invention relates to the field of printing technology, and in particular to an automatic inking system. Background Technology

[0002] Corrugated board is a common material at present. During the processing of corrugated board, its surface needs to be printed. The printing work of corrugated board requires the use of a printing press. The ink supply device of the printing press is an essential piece of equipment. During the use of the printing press, ink needs to be delivered to the ink pool of the printing press in order to print on the corrugated board.

[0003] In existing technologies, when supplying ink to the ink tank of a printing press, ink from the ink bucket is usually directly pumped into the ink tank using an oil pump. Ink in the ink bucket that is not supplied has low fluidity during storage and is prone to sedimentation and clumping, which affects the printing quality during ink printing. Summary of the Invention

[0004] This application provides an automatic inking system that reduces the possibility of ink settling and clumping during storage, thereby improving the printing quality of the ink during printing.

[0005] The automatic inking system provided in this application adopts the following technical solution:

[0006] An automatic inking system includes a base; an ink storage tank is mounted on the top surface of the base; a pump body is mounted on the top surface of the ink storage tank; an inlet pipe is fixedly connected to the input end of the pump body, and an outlet pipe is fixedly connected to the output end of the pump body; an ink delivery pipe is mounted on one side of the ink storage tank; an ink supply pipe communicating with the ink delivery pipe is fixedly connected to the side wall of the ink delivery pipe; the end of the inlet pipe away from the pump body extends into the ink storage tank and communicates with the ink storage tank; the end of the outlet pipe away from the pump body communicates with the interior of the ink delivery pipe; a motor is mounted on the bottom surface of the base; a rotating shaft extending into the ink storage tank is fixedly connected to the output end of the motor; a stirring plate is fixedly connected to the outer wall of the rotating shaft; and an ink extrusion mechanism located on one side of the ink storage tank is mounted on the top surface of the base; the ink extrusion mechanism can transport ink from the ink tank to the ink storage tank.

[0007] By adopting the above technical solution, the ink tank containing the ink is placed on the top surface of the base. The ink is conveyed to the ink storage tank by the ink extrusion mechanism. When ink needs to be conveyed to the ink pool of the printing press, the pump is started to convey the ink in the ink storage tank to the ink delivery pipe through the inlet and outlet pipes. The ink in the ink delivery pipe is then conveyed to the ink pool in the printing press through the ink supply pipe. When the ink is stored in the ink storage tank, the motor is started to drive the rotating shaft to rotate. During the rotation of the rotating shaft, the stirring plate is driven to stir the ink, which promotes the movement of the ink in the ink tank, improves the fluidity of the ink, and makes it less likely for the ink to precipitate and clump in the ink storage tank, thereby improving the printing quality during ink printing.

[0008] Preferably, the ink extrusion mechanism includes a pair of electric push rods and a pad mounted on the top surface of the base; the pad is fixedly connected to the output end of the pair of electric push rods, and a cylinder is mounted on the bottom surface of the pad; a pressure plate is fixedly connected to the output end of the cylinder; a connecting pipe extending to the top of the pressure plate is fixedly connected to the bottom surface of the pressure plate; the end of the connecting pipe away from the pressure plate is connected to the ink storage box.

[0009] By adopting the above technical solution, the electric actuator is activated to drive the cylinder and pressure plate to rise. Then, the ink barrel containing ink is placed at the bottom of the pressure plate. The electric actuator is activated to drive the cylinder and pressure plate to move down so that the pressure plate comes into contact with the ink in the ink barrel. The cylinder is activated to drive the pressure plate to move down and squeeze the ink, so that the ink in the ink barrel is transported to the ink storage box through the connecting pipe, making it convenient for staff to transfer the ink in the ink barrel to the ink storage box for storage.

[0010] Preferably, a lead screw is rotatably connected to the inner side wall of the bottom end of the ink storage box; a scraper is sleeved on the outer side wall of the lead screw and contacts the inner side wall of the ink storage box; the scraper is threadedly driven to the outer side wall of the lead screw, and a piercing rod is fixedly connected to the inner side wall of the scraper; a spike is provided on the outer side wall of the piercing tube; and a transmission component is provided on the lead screw that can be driven to rotate by a rotating shaft.

[0011] By adopting the above technical solution, during the process of the rotating shaft driving the stirring plate, the rotating shaft drives the lead screw to rotate through the transmission component. During the rotation of the lead screw, the scraper slides along the inner wall of the ink storage tank. During the sliding process, the scraper scrapes the ink on the inner wall of the ink storage tank, making it less likely for the ink to stick to the inner wall of the ink storage tank. In addition, during the sliding process, the scraper drives the piercing rod to move. The spikes set on the piercing rod pierce the air bubbles in the ink, reducing the air bubble content in the ink and improving the printing quality of the ink.

[0012] Preferably, the bottom end of the lead screw passes through the ink storage box and the base and extends to the bottom of the base; the transmission component includes a first pulley fixed to the outer wall of the rotating shaft and a belt sleeved on the first pulley; the end of the lead screw extending to the bottom of the base is fixed to a second pulley; the end of the belt away from the first pulley is sleeved on the outside of the second pulley, and the belt causes the first pulley and the second pulley to move together.

[0013] By adopting the above technical solution, the rotating shaft drives the first pulley to rotate during rotation. Under the transmission action of the first pulley, the second pulley and the belt, the rotating shaft drives the lead screw to rotate. The forward and reverse rotation of the lead screw is achieved by the motor driving the rotating shaft to rotate in both directions.

[0014] Preferably, the rotating shaft has a first cavity; the stirring plate has a second cavity communicating with the first cavity; a push plate is slidably connected to the inner wall of the second cavity, and a first rotating shaft located on the side of the push plate away from the first cavity is rotatably connected to the inner wall of the second cavity; the end of the first rotating shaft extends through the stirring plate and out of the stirring plate, a pointed rod is fixedly connected to the outer wall of the first rotating shaft extending out of the stirring plate, and a gear is fixedly connected to the outer wall of the first rotating shaft located in the second cavity; a rack that meshes with the gear is fixedly connected to the side wall of the push plate near the gear; the rack slides in cooperation with the inner wall of the second cavity, and the end of the rack away from the push plate is connected to the inner wall of the second cavity through a first spring; the top surface of the ink storage box is provided with an air supply mechanism that can supply air into the first cavity to drive the push plate to slide towards the gear.

[0015] By adopting the above technical solution, when the stirring plate stirs the ink, air is supplied to the first cavity through the air supply mechanism set on the top surface of the ink storage box. The push plate slidably connected in the second cavity slides towards the gear under the action of air pressure. During the sliding process of the push plate, the rack slides and compresses the first spring. During the sliding process of the rack, the gear and the first rotating shaft rotate, thereby driving the tip rod to rotate. The rotating tip rod breaks up the air bubbles in the ink and reduces the air bubble content in the ink.

[0016] Preferably, the air supply mechanism includes a concave shell, an air bladder, and a pressing component fixed to the top surface of the ink storage tank; the concave shell is fixed to the top surface of the ink storage tank, and a pressing block that can extend out of the concave shell is connected to the inner side wall of the concave shell by a second spring; the air bladder is disposed inside the concave shell, and the air bladder contacts the side wall of the pressing block connected by the second spring, and an air supply pipe is connected to the air bladder; the end of the air supply pipe away from the air bladder extends into the first cavity and communicates with the first cavity; the top end of the lead screw extends to the top of the ink storage tank; the pressing component is disposed at the top end of the lead screw, and the pressing component can drive the pressing block to press the air bladder.

[0017] By adopting the above technical solution, the lead screw drives the extruder to move during rotation. After the extruder contacts the pressure block, it pushes the pressure block to squeeze the airbag. After the airbag is compressed, the gas inside enters the first cavity through the air supply pipe, which increases the air pressure inside the first cavity. The push plate sliding on the inner wall of the second cavity is pushed along the inner wall of the second cavity under the action of air pressure.

[0018] Preferably, the side wall of the pressure block away from the first spring has an arc surface; the extrusion member includes a cam fixed to the top of the lead screw; the cam can contact and cooperate with the arc surface to push the pressure block to extrude the airbag.

[0019] By adopting the above technical solution, the lead screw drives the cam to rotate during the rotation process. The cam gradually approaches the pressure block and contacts the arc surface during the rotation process. Through the cooperation between the cam and the arc surface, the cam pushes the pressure block to squeeze the air bag to deliver air. When the cam loses contact with the arc surface, the pressure block slides back to the initial position under the elastic force of the second spring, so that the cam can squeeze the pressure block again.

[0020] Preferably, the end of the rotating shaft away from the motor extends to the top of the ink storage tank; an end cap covering the outside of the rotating shaft is fixedly connected to the top surface of the ink storage tank; the rotating shaft is rotatably engaged with the inner wall of the end cap; the end of the air supply pipe away from the air bladder passes through the end cap and extends into the first cavity; a sealing ring is fixedly connected to the inner wall of the end cap that contacts the air supply pipe.

[0021] By adopting the above technical solution, the end of the gas delivery tube away from the airbag passes through the end cap and extends into the interior of the rotating shaft, so that the gas delivery tube is connected to the interior of the first cavity. The end cap keeps the gas delivery tube stable, and the sealing ring on the end cap improves the sealing performance of the end cap, making it less likely for the gas inside the airbag to leak.

[0022] Preferably, an exhaust pipe communicating with the interior of the ink storage box is fixedly connected to the top surface of the ink storage box; a first valve is provided on the exhaust pipe; and a second valve is provided on the connecting pipe.

[0023] By adopting the above technical solution, when the pressure plate squeezes the ink for conveying, the first valve on the exhaust pipe and the second valve on the connecting pipe are opened; the exhaust pipe is set to keep the air pressure in the ink storage box stable; when the ink tank is replaced, the second valve on the connecting pipe is closed, so that the ink in the connecting pipe is not easy to flow out of the connecting pipe and cause waste.

[0024] Preferably, a sealing groove is provided on the outer wall of the pressure plate; a sealing strip is fixedly connected in the sealing groove.

[0025] By adopting the above technical solution, when the pressure plate squeezes the ink in the ink barrel, the ink is transported to the ink storage box through the connecting pipe. The sealing strip set in the sealing groove improves the sealing performance of the ink barrel when the pressure plate squeezes the ink, and reduces the possibility of ink leakage at the contact point between the pressure plate and the inner wall of the ink barrel.

[0026] In summary, this application has the following beneficial effects:

[0027] 1. By starting the cylinder, the pressure plate is moved down, which squeezes the ink and delivers it into the ink storage tank through the connecting pipe. During the ink storage process in the ink storage tank, the motor is started. The motor drives the rotating shaft and the stirring plate to rotate. During the rotation of the stirring plate, the ink moves in the ink storage tank, which improves the fluidity of the ink and makes it less likely to precipitate and clump during storage, thus improving the printing quality of the ink.

[0028] 2. During the rotation of the rotating shaft, the transmission action of the first pulley, the second pulley and the belt drives the lead screw to rotate, thereby causing the scraper sleeved on the outside of the lead screw to slide along the lead screw. The scraper scrapes the ink on the inner wall of the ink storage box, making it less likely for the ink to stick to the inner wall of the ink storage box and form clumps. In addition, the scraper drives the piercing rod to move during the sliding process, so that the spikes pierce the air bubbles in the ink and reduce the air bubble content in the ink.

[0029] 3. During the rotation of the lead screw, the cam gradually contacts the pressure block and the arc surface of the pressure block. Through the cooperation between the cam and the arc surface, the cam pushes the pressure block to squeeze the air bladder, so that the gas inside the air bladder is transported to the first cavity to squeeze the push plate to slide. The push plate drives the rack to compress the second spring and drives the gear and the first rotating shaft to rotate, thereby driving the tip rod to rotate. As the stirring plate rotates, the tip rod breaks the air bubbles in the ink, further reducing the air bubble content in the ink and improving the printing quality during ink printing.

[0038] The present invention will be further described in detail below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0039] This invention discloses an automatic inking system, such as... Figure 1 and Figure 2As shown, the system includes a base 1, an ink reservoir 2, an ink extrusion mechanism 5, a pump body 3, and an ink delivery pipe 4. The ink reservoir 2 is fixed to the top surface of the base 1. The ink extrusion mechanism 5 is located on one side of the ink reservoir 2 and includes a pair of electric actuators 51, a pad 52, and a cylinder 53 located on one side of the ink reservoir 2. The pair of electric actuators 51 are fixed to the top surface of the base 1, and the pad 52 is fixed to the output end of the pair of electric actuators 51. The cylinder 53 is fixed to the bottom of the pad 52, and a pressure plate 54 that can extend into the ink tank is fixed to the piston rod end of the cylinder 53. A connecting pipe 55 extending to the top of the pressure plate 54 is fixed to the bottom surface of the pressure plate 54. The connecting pipe 55 is located away from the pressure plate 54. The end is fixed to the top surface of the ink storage tank 2, and the connecting pipe 55 is connected to the inside of the ink storage tank 2; the ink supply pipe 4 is set on one side of the ink storage tank 2, and multiple ink supply pipes 41 connected to the inside of the ink supply pipe 4 are fixed to the side wall of the ink supply pipe 4. A third valve 411 is set at the end of the ink supply pipe 4 away from the ink supply pipe 4; the pump body 3 is fixed to the top surface of the ink storage tank 2, and the inlet pipe 31 is fixed to the input end of the pump body 3. The outlet pipe 32 is fixed to the output end of the pump body 3; the end of the inlet pipe 31 away from the pump body 3 penetrates the top side wall of the ink storage tank 2 and extends into the inside of the ink storage tank 2. The end of the outlet pipe 32 away from the pump body 3 is fixed to the side wall of the ink supply pipe 4 and is connected to the inside of the ink supply pipe 4.

[0040] After the electric actuator 51 is activated, the pad 52 and cylinder 53 are raised, and the ink tank containing ink is placed on the base 1. The electric actuator 51 is activated, and the pad 52 and cylinder 53 are moved down so that the pressure plate 54 comes into contact with the ink. Then, the cylinder 53 is activated, and the pressure plate 54 is moved down to squeeze the ink. The ink is transported into the ink storage tank 2 through the connecting pipe 55. When the ink filling operation is performed, the third valve 411 on the ink filling pipe 41 is opened, and the pump body 3 is activated to transport the ink in the ink storage tank 2 to the ink supply pipe 4 through the liquid inlet pipe 31 and the liquid outlet pipe 32. The ink entering the ink supply pipe 4 is transported to the ink pool of the printing machine through the ink filling pipe 41.

[0041] like Figure 1 and Figure 2 As shown, an exhaust pipe 25 communicating with the inside of the ink storage box 2 is fixedly connected to the top surface of the ink storage box 2. A first valve 251 is provided on the exhaust pipe 25, and a second valve 551 is provided on the connecting pipe 55. An annular sealing groove 541 is provided on the outer wall of the pressure plate 54, and an annular sealing strip 542 is fixedly connected in the sealing groove 541.

[0042] The sealing strip 542 fixed inside the sealing groove 541 ensures good sealing of the ink tank when the pressure plate 54 squeezes the ink, reducing the possibility of ink flowing to the top of the pressure plate 54 through the gap between the pressure plate 54 and the ink tank. The exhaust pipe 25 and the first valve 251 ensure that the pressure in the ink storage tank 2 remains stable when the ink is transported. The second valve 551 on the connecting pipe 55 prevents ink from flowing back out of the connecting pipe 55 and causing waste when the ink tank is replaced.

[0043] like Figure 3 As shown, a motor 11 is installed on the bottom surface of the base 1; a rotating shaft 12 is fixedly connected to the output end of the motor 11; the rotating shaft 12 passes through the bottom inner wall of the base 1 and the ink storage box 2 and extends into the inside of the ink storage box 2; multiple stirring plates 13 are fixedly connected to the outer wall of the rotating shaft 12.

[0044] When storing ink in the ink storage tank 2, the motor 11 is started to drive the rotating shaft 12 and the stirring plate 13 to rotate. When the stirring plate 13 rotates, it causes the ink in the ink storage tank 2 to flow, improving the fluidity of the ink. This makes it less likely for the ink to clump when stored in the ink storage tank 2, thus improving the printing quality when the ink is used for printing.

[0045] like Figure 3 and Figure 4 As shown, a lead screw 21 is rotatably connected to the inner side wall of the bottom end of the ink storage box 2; a scraper 22 is sleeved on the outer side wall of the lead screw 21 and contacts the inner side wall of the ink storage box 2; the scraper 22 is threadedly driven to the outer side wall of the lead screw 21, the scraper 22 is annular, and a plurality of spaced piercing rods 23 are fixedly connected to the inner side wall of the scraper 22; a plurality of spikes 231 are fixedly connected to the outer side wall of the piercing rods 23. The bottom end of the lead screw 21 passes through the inner side wall of the bottom end of the ink storage box 2 and the base 1 and extends to the bottom of the base 1. The end of the lead screw 21 extending to the bottom of the base 1 is provided with a transmission component 24 that can be driven to rotate by the rotating shaft 12. The transmission component 24 includes a first pulley 241, a second pulley 243 and a belt 242. The first pulley 241 is fixed to the outer side wall of the rotating shaft 12 located at the bottom of the base 1. The second pulley 243 is fixed to the outer side wall of the lead screw 21 extending to the bottom of the base 1. The belt 242 is sleeved on the outside of the first pulley 241 and the second pulley 243, and the belt 242 makes the first pulley 241 and the second pulley 243 move together.

[0046] During the rotation of the rotating shaft 12, the lead screw 21 rotates through the transmission action of the first pulley 241, the second pulley 243, and the belt 242. During the rotation of the lead screw 21, the scraper 22 slides along the lead screw 21. The scraper 22 scrapes the ink on the inner wall of the ink storage tank 2, making it less likely for the ink to stick to the inner wall of the ink storage tank 2, thus reducing the possibility of ink clumping together. In addition, during the sliding process, the scraper 22 drives the piercing rod 23 to move. The spikes 231 on the piercing rod 23 pierce the air bubbles in the ink during the movement of the piercing rod 23, reducing the air bubble content in the ink. This makes the ink delivered to the ink pool of the printing press less likely to contain too many air bubbles, thus improving the printing quality of the ink.

[0047] like Figure 3 and Figure 5As shown, a first cavity 121 is formed inside the rotating shaft 12 along the axial direction of the rotating shaft 12. A second cavity 131 is formed inside the stirring plate 13, communicating with the first cavity 121. A push plate 132 is slidably connected to the inner wall of the second cavity 131. A rack 136 is fixedly connected to the side wall of the push plate 132 away from the first cavity 121, and slides with the inner wall of the second cavity 131. A first spring 137 is fixedly connected to the end of the rack 136 away from the push plate 132. The end of the first spring 137 away from the rack 136 is connected to the first spring 137. The inner walls of the two cavities 131 are fixedly connected. A first rotating shaft 133 with both ends extending to the outside of the stirring plate 13 is rotatably connected to the inner wall of the second cavity 131. A pair of pointed rods 134 are fixedly connected to the side wall of the first rotating shaft 133 extending to the outside of the stirring plate 13. A gear 135 that meshes with the rack 136 is fixedly connected to the outer side wall of the first rotating shaft 133 located inside the second cavity 131. An air supply mechanism 6 is provided on the top surface of the ink storage box 2, which can supply air to the first cavity 121. The air supply mechanism 6 can push the push plate 132 to move towards the first spring 137.

[0048] Gas is supplied into the first cavity 121 through the gas supply mechanism 6, causing the gas entering the first cavity 121 to compress the push plate 132 and slide it towards the first spring 137. During the sliding process, the push plate 132 drives the rack 136 to compress the first spring 137, and drives the gear 135 and the first rotating shaft 133 to rotate. During the rotation of the first rotating shaft 133, the tip rod 134 rotates, causing the tip rod 134 to break up the air bubbles in the ink, further reducing the air bubble content in the ink.

[0049] like Figure 3 , Figure 5 and Figure 6 As shown, the air delivery mechanism 6 includes a concave shell 61, an air bladder 62, a pressure block 65 that can extend out of the concave shell 61, and a pressing member 63 that can drive the pressure block 65 to squeeze the air bladder 62. The concave shell 61 is fixedly connected to the top surface of the ink storage box 2. The pressure block 65 is slidably connected to the inner wall of the concave shell 61. The side wall of the pressure block 65 that can extend out of the concave shell 61 is provided with an arc surface 651. A second spring 64 is fixedly connected to the side wall of the pressure block 65 away from the arc surface 651. The end of the second spring 64 away from the pressure block 65 is fixedly connected to the inner wall of the concave shell 61. The air bladder 62 is disposed in the concave shell. Inside 61, the airbag 62 is located on the side of the pressure block 65 away from the arc surface 651. The airbag 62 is in contact with the side wall of the pressure block 65 connected to the second spring 64. An air supply pipe 621 extending out of the concave shell 61 is connected to the airbag 62. The end of the air supply pipe 621 away from the airbag 62 extends into the first cavity 121. The air supply pipe 621 is rotatably engaged with the inner side wall of the rotating shaft 12. The extrusion member 63 is located at the top of the lead screw 21 extending out of the ink storage box 2. The extrusion member 63 includes a cam 631 fixed to the top of the lead screw 21. The cam 631 engages with the arc surface 651.

[0050] During the rotation of the lead screw 21, the cam 631 gradually contacts the pressure block 65 and the arc surface 651 of the pressure block 65. Through the cooperation between the cam 631 and the arc surface 651, the cam 631 pushes the pressure block 65 to squeeze the air bladder 62. After the air bladder 62 is compressed, the gas inside the air bladder 62 is transported to the first cavity 121 through the air supply pipe 621. When the cam 631 loses contact with the arc surface 651, the pressure block 65 resets under the elastic force of the first spring 137, so that the cam 631 can squeeze the pressure block 65 again.

[0051] like Figure 3 , Figure 6 and Figure 7 As shown, the end of the rotating shaft 12 away from the motor 11 extends to the top of the ink storage tank 2; an end cap 66 is fixedly attached to the top surface of the ink storage tank 2, covering the outside of the rotating shaft 12; the rotating shaft 12 and the inner wall of the end cap 66 are rotatably engaged; the end of the air supply pipe 621 away from the air bag 62 passes through the end cap 66 and extends into the interior of the rotating shaft 12; a sealing ring 661 is fixedly attached to the inner wall of the end cap 66 that contacts the air supply pipe 621; the sealing performance of the end cap 66 is improved by the sealing ring 661 on the end cap 66, making it less likely for the gas inside the air bag 62 to leak.

[0052] Working principle: The electric actuator 51 drives the pad 52 and cylinder 53 to rise, placing the ink tank containing ink on the base 1. The electric actuator 51 is activated to drive the pad 52 and cylinder 53 to move down, so that the pressure plate 54 comes into contact with the ink. The cylinder 53 is activated to drive the pressure plate 54 to move down, so that the pressure plate 54 squeezes the ink and delivers it into the ink storage tank 2 through the connecting pipe 55. The sealing strip 542 installed on the side wall of the pressure plate 54 ensures that the ink tank has good sealing performance when the pressure plate 54 squeezes the ink, reducing the possibility of ink leakage through the gap between the pressure plate 54 and the inner side wall of the ink tank. When the ink is being filled, the pump body 3 delivers the ink in the ink storage tank 2 to the ink delivery pipe 4 through the inlet pipe 31 and the outlet pipe 32. The ink in the ink delivery pipe 4 is then delivered to the ink pool of the printing press through the ink filling pipe 41.

[0053] During the ink storage process in ink storage tank 2, motor 11 is started. Motor 11 drives rotating shaft 12 and stirring plate 13 to rotate. During the rotation of stirring plate 13, the ink moves in ink storage tank 2, improving the fluidity of the ink and making it less likely to precipitate and clump during storage, thus improving the printing quality of the ink.

[0054] Under the transmission action of the first pulley 241, the second pulley 243 and the belt 242, the rotating shaft 12 rotates, which drives the lead screw 21 to rotate. This causes the scraper 22 sleeved on the outside of the lead screw 21 to slide along the lead screw 21. During the sliding process, the scraper 22 scrapes the ink on the inner wall of the ink storage box 2, making it less likely for the ink to stick to the inner wall of the ink storage box 2. During the sliding process, the scraper 22 drives the piercing rod 23 to move. The spikes 231 set on the piercing rod 23 pierce the air bubbles in the ink, reducing the air bubble content in the ink. The motor 11 drives the rotating shaft 12 to rotate forward and backward, which causes the lead screw 21 to rotate forward and backward, realizing the up and down reciprocating motion of the scraper 22.

[0055] During the rotation of the lead screw 21, the cam 631 gradually contacts the pressure block 65 and the arc surface 651 of the pressure block 65. Through the cooperation between the cam 631 and the arc surface 651, the cam 631 pushes the pressure block 65 to compress the airbag 62. After the airbag 62 is compressed, the gas inside the airbag 62 is transported to the first cavity 121 through the air supply pipe 621. The gas entering the first cavity 121 compresses the push plate 132 to slide. The push plate 132 drives the rack 136 to compress the second spring 64 and drive the gear 135 and the first rotating shaft 133 to rotate. During the rotation of cam 63, the pointed rod 134 rotates, causing the pointed rod 134 to break the air bubbles in the ink as the stirring plate 13 rotates, further reducing the air bubble content in the ink. When the cam 631 loses contact with the arc surface 651, the pressure block 65 resets under the elastic force of the first spring 137, making it easier for the cam 631 to squeeze the pressure block 65 again. When the pressure block 65 resets, the rack 136 slides back under the elastic force of the second spring 64, causing the pointed rod 134 to rotate in the opposite direction to break the air bubbles, thus improving the efficiency of the pointed rod 134 in breaking the air bubbles.

[0056] The exhaust pipe 25 and the first valve 251 on the top surface of the ink storage box 2 keep the pressure inside the ink storage box 2 stable. The second valve 551 on the connecting pipe 55 is closed when the ink tank is replaced, so that the ink in the connecting pipe 55 is not easy to flow out of the connecting pipe 55 and cause waste.

[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
