DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0034] Embodiment 1: Please refer to Figures 1-11 The present application provides a technical solution: an ink jet printer for cheese packaging, comprising a conveyor belt 1, a packaging bag 2, a shell 3 and a spray pipe 4 arranged on one side of the shell 3, further comprising:

[0035] A storage tank 5 is arranged in the shell 3 for storing ink. A stirring plate 6 is arranged in the storage tank 5 for stirring the ink in the storage tank 5 to separate the gas bubbles mixed in the ink from the ink.

[0036] A stirring assembly 7 is arranged in the storage tank 5 for providing the power required for the rotation of the stirring plate 6 to drive the stirring plate 6 to stir the ink in the storage tank 5, so that the ink in the storage tank 5 generates centrifugal force to separate the gas bubbles in the ink from the ink.

[0037] A pressure control member 8 is arranged above the storage tank 5 for controlling the air pressure in the storage tank 5 to keep the storage tank 5 in a low vacuum state during the rotation of the stirring plate 6, so that the ink is separated from the gas bubbles.

[0038] A replenishment opening 14 is arranged on the top of the storage tank 5. A threaded groove 15 is formed on the outer side of the replenishment opening 14. A sealing cover 16 is arranged on the top of the replenishment opening 14 and is threadedly connected with the replenishment opening 14 through the threaded groove 15. When the staff needs to replenish or pour ink into the storage tank 5, the sealing cover 16 is rotated along the threaded groove 15 on the outer side of the replenishment opening 14 until the sealing cover 16 can be separated from the replenishment opening 14, and then the ink can be poured into the storage tank 5 through the replenishment opening 14. After the replenishment of the ink is completed, the sealing cover 16 can be screwed on the replenishment opening 14 along the threaded groove 15. The function is to ensure that the storage tank 5 remains sealed during operation to prevent external impurities from entering or ink from leaking, ensuring the stability and clarity of the coding process. At the same time, this structure design also facilitates regular inspection and maintenance of the ink inventory by the operator, improving the overall safety and work efficiency of the equipment.

[0039] The stirring assembly 7 comprises a driving member 9 arranged in the shell 3 for generating the power required for the rotation of the stirring plate 6. A rotating member 10 is arranged in the storage tank 5 for assisting the rotation of the stirring plate 6 in the storage tank 5.

[0040] The driving member 9 comprises a motor 91 arranged in the shell 3, and the motor 91 is provided with a driving rod 92 at the output end, and the driving rod 92 is provided with a driving plate 93 at the end away from the motor 91, and the stirring plate 6 is arranged on the top of the driving plate 93. After the ink is replenished, the motor 91 is started, and the motor 91 drives the driving rod 92 at the output end to rotate, so that the driving rod 92 drives the driving plate 93 to rotate quickly, and the plurality of stirring plates 6 arranged on the top of the driving plate 93 rotate quickly, so that the ink in the storage tank 5 is fully stirred, and the centrifugal force generated by the stirring plate 6 rotating quickly can make the ink uniformly distributed on the inner wall of the storage tank 5. While ensuring that the ink is uniformly mixed and has no sediment, the bubbles in the ink can also be separated out, thereby improving the purity of the ink and the code printing quality, so that the bubbles in the ink quickly gather towards the center position of the storage tank 5. The purpose is to avoid the phenomenon of code printing breakpoint or blur caused by residual bubbles, further improve the clarity and accuracy of code printing, and at the same time, the efficient operation of the stirring assembly 7 can also effectively prevent the stratification or sedimentation problem of the ink caused by long-term standing during storage, so as to ensure that the ink is always in a uniform and stable state, thereby providing reliable protection for the continuous and high-quality operation of the code printing equipment.

[0041] The rotating member 10 comprises a first rotating plate 101 arranged at the bottom of the driving plate 93, and a second rotating plate 102 is arranged at the bottom of the inner wall of the storage tank 5. The opposite sides of the first rotating plate 101 and the second rotating plate 102 are both provided with rotating grooves 103, and a plurality of rolling balls 104 are arranged between the first rotating plate 101 and the second rotating plate 102, and the plurality of rolling balls 104 are rotatably arranged in the two rotating grooves 103. When the driving plate 93 rotates, the first rotating plate 101 arranged at the bottom of the driving plate 93 will rotate synchronously, and the rolling balls 104 arranged in the rotating grooves 103 will roll in the rotating grooves 103, thereby reducing the frictional resistance in the rotating process of the driving plate 93, improving the smoothness and stability of the rotation, and further ensuring that the driving plate 93 always maintains a uniform stress state during rotation, avoiding equipment vibration or abnormal wear caused by uneven stress. At the same time, the rolling of the rolling balls 104 can also effectively reduce energy consumption, so that the motor 91 operates more efficiently and energy-savingly. The overall structure design is reasonable, which not only prolongs the service life of the equipment, but also improves the reliability and stability of the inkjet printer during continuous operation.

[0042] The pressure control member 8 comprises a first gas conveying pipe 81 arranged at the top of the storage tank 5 and communicating with the storage tank 5, and the first gas conveying pipe 81 is provided with a micro air pump 82 at the end away from the storage tank 5, and the first gas conveying pipe 81 is arranged at the air inlet end of the micro air pump 82, and the air outlet end of the micro air pump 82 is provided with a second gas conveying pipe 83. During the rotation of the driving plate 93, the micro air pump 82 is started, which will extract the gas in the storage tank 5 through the first gas conveying pipe 81 and discharge the extracted gas into the external air through the second gas conveying pipe 83, so as to form a low-vacuum environment in the storage tank 5, so that the gas pressure in the storage tank 5 is extracted to 10-30 kPa absolute pressure. In this state, the gas bubbles in the ink will accelerate to the center of the storage tank 5 under the action of low pressure and quickly break and discharge, thereby further improving the deaeration efficiency and purity of the ink. At the same time, the vacuum environment can effectively inhibit the re-adsorption of air in the ink due to high-speed rotation during stirring, ensuring that the ink remains stable during the entire stirring and conveying process, and providing high-quality ink supply for subsequent code spraying operations.

[0043] The stirring plates 6 are arranged in multiple numbers and are all arc-shaped, and the multiple stirring plates 6 are arranged in a ring-shaped equidistant array with the driving plate 93 axis as the center. The driving plate 93 axis is provided with a conical plate 11, which can effectively guide the ink to flow to the inner wall of the storage tank 5 when the driving plate 93 rotates, avoiding the accumulation of ink in the central region of the driving plate 93, so that the gas bubbles in the ink are more easily separated out, thereby further improving the uniformity of the ink and the code spraying effect, and reducing the code spraying blur or code break phenomenon caused by residual gas bubbles. In addition, the arc-shaped shape of the stirring plate 6 can effectively reduce the resistance generated during stirring and more easily drive the ink to flow, so that the gas bubbles in the ink are more easily brought out of the ink liquid surface. Through the continuous disturbance action of the arc-shaped stirring plate 6, the ink forms a spiral circulating flow in the storage tank 5, so that the ink is more easily to form a centrifugal field during rapid rotation, thereby further promoting the separation and discharge of residual gas bubbles in the ink, improving the overall stability and uniformity of the ink. At the same time, this spiral flow can effectively prevent dead angles in the storage tank 5, ensuring that the ink always maintains full circulation during stirring, further improving the working efficiency and code spraying quality of the code spraying equipment.

[0044] The storage tank 5 is provided with a bubble eliminating member 12, which is used to break the bubbles separated from the ink. The bubble eliminating member 12 comprises an electric push rod 121 arranged in the shell 3, the output end of the electric push rod 121 is provided with a pressing rod 122, the end of the pressing rod 122 away from the electric push rod 121 is provided with a pressing plate 123, the shell 3 is provided with a pressing pipe 124, the pressing plate 123 is slidingly arranged in the pressing pipe 124, the top of the pressing pipe 124 is provided with an alcohol tank 125 for storing alcohol, the bottom end of the alcohol tank 125 is provided with a first one-way valve 126, the opening direction of the first one-way valve 126 is downward, the end of the pressing pipe 124 away from the pressing rod 122 is provided with a liquid delivery pipe 127, the liquid delivery pipe 127 is communicated with the pressing pipe 124, the liquid delivery pipe 127 is provided with a second one-way valve 128, and the opening direction of the second one-way valve 128 is upward.

[0045] The support pipe 129 is arranged in the storage tank 5 and located at the axis of the storage tank 5, the synchronization pipe 1210 is arranged in the support pipe 129, the synchronization pipe 1210 is communicated with the infusion pipe 127, a plurality of spray heads 1211 are arranged in the synchronization pipe 1210 and extend out of the support pipe 129, when the bubbles in the ink are separated, the electric push rod 121 is started, the extrusion rod 122 at the output end of the electric push rod 121 pushes the extrusion plate 123, the extrusion plate 123 is driven to slide in the extrusion pipe 124, when the extrusion plate 123 moves towards the electric push rod 121, the first one-way valve 126 is opened and the second one-way valve 128 is closed, the alcohol in the alcohol tank 125 enters the extrusion pipe 124 through the first one-way valve 126, when the extrusion plate 123 moves away from the electric push rod 121, the first one-way valve 126 is closed and the second one-way valve 128 is opened, the alcohol in the extrusion pipe 124 is pushed into the infusion pipe 127 under the action of the extrusion plate 123, the alcohol entering the infusion pipe 127 enters the synchronization pipe 1210 along the infusion pipe 127, is uniformly distributed to each spray head 1211 through the synchronization pipe 1210, and forms mist alcohol after passing through the spray head 1211, so that the mist alcohol falls on the surface of the ink bubbles, thereby rapidly dissolving the separated ink bubbles, further improving the purity and stability of the ink, the support pipe 129 arranged in the storage tank 5 can effectively support the plurality of spray heads 1211 and keep a uniform distribution interval, avoiding uneven code or ink splashing caused by position deviation of the spray head 1211, the detachable connection structure is adopted between the support pipe 129 and the spray head 1211, which is convenient for daily maintenance and replacement, at the same time, the surface of the spray head 1211 is sprayed with an anti-corrosion coating, effectively prolonging the service life of the spray head 1211, avoiding corrosion or blockage caused by long-term contact with the ink, further improving the stability and durability of the equipment, which acts on the mist alcohol sprayed by the spray head 1211 to rapidly break and dissolve the bubbles in the ink, thereby preventing the bubbles from interfering with the code effect and ensuring the clarity and integrity of the code pattern, at the same time, the structure design is reasonable and the operation is simple, which not only improves the stability of the code equipment operation, but also reduces the maintenance cost, and is suitable for ink code application in various industrial environments.

[0046] The discharge part 13 is arranged at the bottom of the storage tank 5 and is used for conveying the ink in the storage tank 5 after the bubble separation to the spray pipe 4, the discharge part 13 comprises a discharge pipe 131 arranged at the bottom of the storage tank 5, the discharge pipe 131 is provided with a discharge pump 132 at the end away from the storage tank 5, the discharge pump 132 is provided with a connecting pipe 133 at the output end, and the connecting pipe 133 is used in cooperation with the spray pipe 4;

[0047] The storage tank 5 is provided with a discharge groove 134, a discharge pipe 131 communicates with the storage tank 5 through the discharge groove 134, an auxiliary pipe 135 is arranged in the storage tank 5 and is located at the same axis as the discharge groove 134, an auxiliary groove 136 is arranged at the top of the auxiliary pipe 135, an auxiliary frame 137 is arranged in the auxiliary pipe 135, an auxiliary spring 138 is arranged at the top of the auxiliary frame 137, a rubber pad 139 matched with the auxiliary groove 136 is arranged at the top of the auxiliary spring 138, the discharge pump 132 is started, the discharge pump 132 will transport the processed ink to the spray pipe 4 through the connecting pipe 133 through the discharge pipe 131, and then the ink is sprayed through the spray pipe 4 for coding operation, when the discharge pump 132 is started, a negative pressure state is generated in the discharge pipe 131, the rubber pad 139 in the auxiliary pipe 135 is adsorbed and moves downward, the auxiliary spring 138 starts to compress and store energy, and the rubber pad 139 is separated from the auxiliary groove 136, so that the ink in the storage pipe can enter the auxiliary pipe 135 through the auxiliary groove 136, and then enter the discharge pipe 131 through the discharge groove 134 after passing through the auxiliary pipe 135, and finally reaches the spray pipe 4 through the discharge pump 132 to complete the coding operation, during the whole conveying process, the rubber pad 139 and the auxiliary groove 136 are always separated, so that the ink continuously and stably flows into the discharge pipe 131, and the phenomenon of flow interruption or backflow caused by pressure change is avoided, when the coding operation is completed, the discharge pump 132 stops running, at this time, the auxiliary spring 138 releases the accumulated elastic force, pushes the rubber pad 139 to reset upward and reseals the auxiliary groove 136, so as to prevent backflow or leakage of residual ink, thereby ensuring the cleanliness and safety of the equipment, and ensuring that the ink bubble separation process in the storage tank 5 is not disturbed by external factors, always maintaining a closed and stable working environment, further improving the stability and reliability of the ink bubble separation.

[0048] In use, when the staff needs to use the ink-jet printer to code the cheese packaging, the cheese packaging is intermittently transported by the conveying belt 1, and when the cheese packaging passes under the ink-jet nozzle 4, the cheese packaging is coded by the ink-jet nozzle 4. This is the prior art and will not be described in detail here. When the staff needs to supplement or pour ink into the storage tank 5, the sealing cover 16 is rotated along the threaded groove 15 outside the refilling opening 14 until the sealing cover 16 can be separated from the refilling opening 14, and then the ink can be poured into the storage tank 5 through the refilling opening 14. After the ink is supplemented, the sealing cover 16 is screwed onto the refilling opening 14 along the threaded groove 15. After the ink is supplemented, the motor 91 is started, which drives the drive rod 92 at the output end to rotate, thereby driving the drive plate 93 to rotate quickly. The plurality of stirring plates 6 arranged at the top of the drive plate 93 rotate quickly, which stirs the ink in the storage tank 5 sufficiently. At the same time, the centrifugal force generated by the quickly rotating stirring plates 6 causes the ink to be evenly distributed on the inner wall of the storage tank 5. This not only ensures that the ink is mixed uniformly without sedimentation, but also separates the bubbles in the ink, thereby improving the purity of the ink and the coding quality. The bubbles in the ink quickly move towards the center of the storage tank 5. When the drive plate 93 rotates, the first rotating plate 101 arranged at the bottom of the drive plate 93 rotates synchronously, and the balls 104 arranged in the rotating groove 103 roll in the rotating groove 103, thereby reducing the frictional resistance during the rotation of the drive plate 93, improving the smoothness and stability of the rotation, and further ensuring that the drive plate 93 always maintains a uniform stress state during rotation, avoiding equipment vibration or abnormal wear caused by uneven stress. At the same time, the rolling of the balls 104 can effectively reduce energy consumption, making the motor 91 operate more efficiently and energy-saving. The overall structure design is reasonable, which not only prolongs the service life of the equipment, but also improves the reliability and stability of the ink-jet printer during continuous operation. When the drive plate 93 rotates, the conical plate 11 arranged on the drive plate 93 can effectively guide the ink to flow to the inner wall of the storage tank 5, avoiding the accumulation of ink in the center area of the drive plate 93, thereby making it easier for the bubbles in the ink to be separated out, further improving the uniformity of the ink and the coding effect, and reducing the phenomenon of blurred or broken codes caused by residual bubbles. In addition, the arc shape of the stirring plate 6 can effectively reduce the resistance generated during stirring, making it easier to move the ink, thereby making it easier for the bubbles in the ink to be brought out of the ink surface;

[0049] During the rotation of the driving plate 93, the micro air pump 82 is started, which will extract the gas in the storage tank 5 through the first gas pipe 81, and discharge the extracted gas into the external air through the second gas pipe 83, so as to form a low vacuum environment in the storage tank 5, so that the gas pressure in the storage tank 5 is extracted to 10-30 kPa absolute pressure, in this state, the gas bubbles in the ink will accelerate to the center of the storage tank 5 under the action of low pressure, and quickly break and discharge, thereby further improving the deaeration efficiency and purity of the ink, at the same time, the vacuum environment can effectively inhibit the re-adsorption of air in the ink due to high-speed rotation during stirring, ensure that the ink always maintains a stable state during the whole stirring and conveying process, and provide high-quality ink supply for subsequent code spraying operation;

[0050] When the gas bubbles in the ink are separated, the electric push rod 121 is started, so that the extrusion rod 122 at the output end of the electric push rod 121 pushes the extrusion plate 123, and drives the extrusion plate 123 to slide in the extrusion pipe 124. When the extrusion plate 123 moves towards the electric push rod 121, the first one-way valve 126 is opened, the second one-way valve 128 is closed, and the alcohol in the alcohol tank 125 enters the extrusion pipe 124 through the first one-way valve 126. When the extrusion plate 123 moves away from the electric push rod 121, the first one-way valve 126 is closed, and the second one-way valve 128 is opened. At this time, the alcohol in the extrusion pipe 124 is pushed into the infusion pipe 127 under the action of the extrusion plate 123, and the alcohol entering the infusion pipe 127 enters the synchronization pipe 1210 along the infusion pipe 127, and is evenly distributed to each nozzle 1211 through the synchronization pipe 1210, and forms mist alcohol after passing through the nozzle 1211, so that the mist alcohol falls on the surface of the separated ink gas bubbles, thereby quickly dissolving the separated ink gas bubbles, further improving the purity and stability of the ink. The support pipe 129 arranged in the storage tank 5 can effectively support the plurality of nozzles 1211 and keep the uniform distribution distance, avoid the uneven code or ink splashing phenomenon caused by the position deviation of the nozzle 1211, the detachable connection structure between the support pipe 129 and the nozzle 1211 facilitates daily maintenance and replacement, at the same time, the surface of the nozzle 1211 is sprayed with an anti-corrosion coating, which effectively prolongs the service life of the nozzle 1211, avoids corrosion or blockage caused by long-term contact with the ink, and further improves the stability and durability of the equipment;

[0051] After the elimination of the ink bubble is completed, the micro-pump 82 and the electric push rod 121 are closed, and the driving board 93 is stopped running, at this time, the ink is in a stable state, and the next step of conveying and code printing operation can be carried out, at this time, the discharge pump 132 is started, the discharge pump 132 will convey the processed ink through the connecting pipe 133 to the spray pipe 4 through the discharge pipe 131, and then the code printing operation is carried out through the spray pipe 4, when the discharge pump 132 is started, the negative pressure state is generated in the discharge pipe 131, so that the rubber pad 139 in the auxiliary pipe 135 is adsorbed and moves downward, so that the auxiliary spring 138 starts to compress the force storage, and the rubber pad 139 is separated from the blocking of the auxiliary groove 136, so that the ink in the storage pipe can enter the auxiliary pipe 135 through the auxiliary groove 136, and then enter the discharge pipe 131 along the discharge groove 134 after passing through the auxiliary pipe 135, and then is conveyed to the connecting pipe 133 through the discharge pump 132, and finally reaches the spray pipe 4 to complete the code printing operation, in the whole conveying process, the rubber pad 139 and the auxiliary groove 136 are always separated, which ensures that the ink continuously and stably flows into the discharge pipe 131, and the phenomena of flow interruption or backflow caused by pressure change are avoided, when the code printing operation is completed, the discharge pump 132 stops running, at this time, the auxiliary spring 138 releases the accumulated elastic force, pushes the rubber pad 139 to reset upward and reseals the auxiliary groove 136, so as to prevent residual ink from flowing back or leaking, so as to protect the cleanliness and safety of the equipment, and also ensure that the ink bubble separation process in the storage tank 5 will not be disturbed by external factors, and always maintains a closed and stable working environment, further improving the stability and reliability of the ink bubble separation.
