Description

Technical Field

[0001] This application relates to the field of packaging printing process equipment, and in particular to a packaging container printing process that enables efficient printing. Background Technology

[0002] Packaging container printing is a comprehensive field that combines materials science, printing technology, and post-processing. Its core lies in selecting the most suitable printing method and process based on the container's material, shape, design requirements, and production volume to achieve an aesthetically pleasing, durable, and economical decorative effect.

[0003] In related technologies, ink quality has a significant impact on packaging printing, and is one of the core factors determining the final quality of printed materials, production efficiency, and even safety. High-quality ink is the cornerstone of obtaining high-quality printed materials, while inferior or unsuitable ink may cause a series of problems, resulting in substandard products, waste products, and even safety hazards.

[0004] If ink is left for a long time after production, the pigments will sink due to gravity, resulting in inconsistent color and concentration between the upper and lower layers. This means that when ink is needed in the packaging printing process, it needs to be properly stirred and heated in advance, which makes the packaging printing process cumbersome and affects the overall efficiency of the packaging printing process. Summary of the Invention

[0005] This application provides a packaging container printing process that enables efficient printing. The purpose is to effectively ensure that the ink can maintain its performance during long-term storage and that the ink can be taken out and used in a timely manner when the packaging printing process needs to use the ink, thereby effectively ensuring the printing efficiency of the packaging printing process.

[0006] This application provides a highly efficient printing process for packaging containers, employing the following technical solution: A highly efficient printing process for packaging containers includes the following steps: S1. Lamination process: A transparent plastic film is applied to the surface of the printed material to protect the printing surface, enhance gloss, and prevent water and stains. S2. Varnishing process: A colorless and transparent coating is applied to the surface of the printed material to form a glossy layer, which enhances the gloss and provides protection. S3. Ink Control: The viscosity and drying speed of the ink are dynamically adjusted according to the paper type and ambient humidity. The ink is stirred in the corresponding storage tank to ensure that its various components, such as resin, solvent and additives, are fully mixed, thereby ensuring the stability and performance of the ink. S4. Die-cutting and creasing process: According to the design requirements, steel knives and steel wires are arranged into templates to cut the printed materials into specific shapes (die-cutting) or to press out lines that are easy to fold (creasing). S5, automated cutting; The oil storage tank is equipped with a stirring device, which includes a stirring shaft and a stirring wheel. The stirring shaft drives the stirring wheel to stir the ink in the oil storage tank. The stirring shaft is connected to an intermittent drive device, which is used to intermittently drive the stirring shaft to rotate.

[0007] By adopting the above technical solution, when the ink in the storage tank is stored for a long time, in order to avoid inconsistencies in pigment and concentration due to prolonged storage, the intermittent drive device can intermittently drive the stirring shaft to rotate. This allows the stirring wheel to intermittently stir the ink in the storage tank, ensuring that various components such as resin, solvent, and additives are fully mixed, thereby ensuring the stability and performance of the ink. When the packaging printing process requires the use of ink, it can be taken out and used in a timely manner, thus effectively ensuring the printing efficiency of the packaging printing process.

[0008] Preferably, the intermittent drive device includes a first drive gear, a first drive rack, a second drive rack, and a second drive gear; The oil storage tank is provided with a first mounting box on one side and a second mounting box at the bottom of the oil storage tank. The first drive gear and the first drive rack are located in the first mounting box, and the second drive rack and the second drive gear are located in the second mounting box. The first drive rack is vertically arranged and meshes with the first drive gear, and the first drive rack moves up and down in the vertical direction; The second drive rack is horizontally arranged and connected to the first drive rack. The first drive rack is used to drive the second drive rack to slide in the horizontal direction. The second drive gear is meshed with the second drive rack. The bottom of the stirring shaft extends downward into the second mounting box, and the second drive gear is integrally sleeved on the periphery of the stirring shaft.

[0009] By adopting the above technical solution, the second drive gear rotates simultaneously, driving the stirring shaft to rotate, which in turn drives the stirring wheel to stir the ink in the oil storage tank.

[0010] Preferably, a first wedge and a second wedge are provided between the first drive rack and the second drive rack. The first wedge is located in the first mounting box and is vertically arranged. The second wedge is located in the second mounting box and is horizontally arranged. One end of the first wedge is integrally connected to the first drive rack, and the other end of the first wedge is wedge-shapedly engaged with the second wedge. The second drive rack is integrally connected to the side wall of the second wedge.

[0011] By adopting the above technical solution, specifically, the first drive rack synchronously drives the first wedge to rise and fall during the lifting and lowering process. During the lifting and lowering process, the first wedge engages with the second wedge in a wedge shape, thereby driving the second wedge to slide horizontally. During the sliding process, the second wedge synchronously drives the second drive rack to slide, and during the sliding process, the second drive rack meshes with the second drive gear, thereby driving the stirring shaft and stirring wheel to rotate, so as to complete the stirring of the ink in the oil storage tank.

[0012] Preferably, the peripheral side of the first drive gear has a smooth portion and a toothed portion.

[0013] By adopting the above technical solution, when the teeth of the first drive gear mesh with the first drive rack, the stirring shaft and the stirring wheel rotate. In this state, the stirring shaft and the stirring wheel complete the stirring of the ink in the oil storage tank. When the teeth of the first drive gear disengage from the first drive rack and the smooth part gradually rotates to the position of the first drive rack, the stirring shaft and the stirring wheel gradually stop rotating. In this state, the stirring shaft and the stirring wheel gradually stop stirring the ink in the oil storage tank.

[0014] By dividing the first drive gear into a smooth part and a toothed part, the engagement between the first drive gear and the first drive rack can be set to be intermittent. This allows for appropriate stirring of the ink during prolonged storage, ensuring thorough mixing of its various components such as resin, solvent, and additives. This guarantees the stability and performance of the ink while effectively preventing over-stirring, which can cause temperature imbalances and affect its performance. Therefore, intermittent stirring ensures appropriate stirring of the ink while effectively avoiding over-stirring.

[0015] Intermittent stirring of the ink during long-term storage ensures its stability and performance, allowing it to be used promptly when needed, thus contributing to the stability of the packaging and printing process.

[0016] Preferably, a lifting seat is provided between the first drive rack and the first wedge, and the upper and lower ends of the lifting seat are integrally connected to the first drive rack and the first wedge, respectively. A fixed pulley is provided in the first mounting box, the lifting seat is located on one side of the fixed pulley, and a counterweight is provided on the other side of the fixed pulley. The lifting seat and the counterweight are connected by a traction belt wrapped around the periphery of the fixed pulley, and the weight of the counterweight is greater than the weight of the lifting seat. A return spring is provided in the second mounting box along the horizontal direction, one end of the return spring is connected to the inner wall of the second mounting box, and the other end of the return spring is connected to the second wedge.

[0017] By adopting the above technical solution, when the first drive gear and the first drive rack mesh, the first drive rack moves downward, simultaneously driving the lifting seat and the first wedge to move downward, at which point the counterweight is lifted. When the first drive gear and the first drive rack disengage, the counterweight moves downward, lifting the lifting seat, which in turn drives the first drive rack to rise until the first drive rack is reset. Simultaneously, as the first drive rack resets, the second wedge is driven to reset synchronously by the reset spring.

[0018] Preferably, a rotating shaft is provided vertically inside the oil storage tank. The rotating shaft is integrally connected to the top of the stirring shaft. A heating box and a cooling box are respectively installed on the left and right sides of the top of the oil storage tank. The stirring shaft is used to drive the rotating shaft to rotate synchronously inside the oil storage tank, and during the rotation of the rotating shaft, the heating box or the cooling box controls the temperature adjustment of the oil storage tank.

[0019] By adopting the above technical solution, the heating box and cooling box are controlled by the rotating shaft to adjust the temperature inside the oil storage tank. This allows the ink in the oil storage tank to be simultaneously subjected to temperature adjustment during intermittent stirring, keeping the ink at a constant temperature. This, in turn, helps to maintain the stability and performance of the ink during long-term storage.

[0020] Preferably, a drive gear is integrally connected to the circumference of the rotating shaft in the horizontal direction. The drive gear is horizontally arranged, and a first bevel gear and a second bevel gear are respectively meshed and connected to the left and right sides of the drive gear. The first bevel gear is connected to the heating box, and the second bevel gear is connected to the cooling box. During the rotation of the drive gear following the rotating shaft, it meshes with the first bevel gear or the second bevel gear respectively. The first bevel gear is used to control the heating box to heat up the oil storage tank, and the second bevel gear is used to control the cooling box to cool down the oil storage tank.

[0021] By adopting the above technical solution, during the rotation of the first bevel gear, the heating box is controlled to inject hot air into the oil storage tank to achieve the heating of the oil storage tank; during the rotation of the second bevel gear, the cooling box is controlled to inject cold air into the oil storage tank to achieve the cooling of the oil storage tank.

[0022] Preferably, the ends of the first bevel gear and the second bevel gear that are far apart from each other are integrally connected with a rotating rod in the horizontal direction. A rotating cam is integrally fitted around the periphery of the rotating rod. A vent plate is installed inside the heating box and the cooling box. A lifting rod is added between the vent plate and the corresponding rotating cam. One end of the lifting rod is connected to the vent plate, and the other end of the lifting rod is connected to the rotating cam.

[0023] By adopting the above technical solution, the first bevel gear and the second bevel gear drive the corresponding rotating rod to rotate synchronously during the rotation process. The rotating rod drives its corresponding rotating cam to rotate. During the rotation of the rotating cam, the lifting rod is driven to rise and fall in the vertical direction. In turn, the lifting rod drives the vent plate to rise and fall in the corresponding heating box or cooling box. During the rise and fall of the vent plate in the heating box or cooling box, the opening and closing of the heating box or cooling box is controlled.

[0024] Preferably, the circumference of the rotating cam also has the smooth portion and the toothed portion, the toothed portion being one-quarter of the circumference of the rotating cam, and the toothed portion being located between the first bevel gear and the second bevel gear.

[0025] By adopting the above technical solution, as the first drive gear and the first drive rack mesh or disengage, during the process of the second wedge sliding to the left and resetting to the right in the second mounting box, the stirring shaft moves in two different states, clockwise and counterclockwise, respectively. This causes the rotating shaft to also move in two different states, clockwise and counterclockwise, which in turn causes the drive gear to rotate clockwise and counterclockwise.

[0026] When the drive gear rotates clockwise, it meshes only with the first bevel gear. In this state, the first bevel gear controls the heating box to heat the oil tank. When the drive gear rotates counterclockwise, it meshes only with the second bevel gear. In this state, the second bevel gear controls the cooling box to cool the oil tank. Thus, by having the drive gear rotate clockwise and counterclockwise, the temperature of the ink in the oil tank is adjusted.

[0027] Preferably, an auxiliary roller is provided between the rotating cam and the lifting rod, and the auxiliary roller is sleeved around the lifting rod.

[0028] By adopting the above technical solution, the auxiliary roller helps to make the connection between the rotating cam and the lifting rod smoother, which in turn helps to ensure the stability of the lifting rod during the lifting process driven by the rotating cam.

[0029] In summary, this application includes at least one of the following beneficial technical effects: 1. When ink is stored in the oil tank for an extended period, to prevent inconsistencies in pigment and concentration due to prolonged storage, the intermittent drive device can intermittently drive the stirring shaft to rotate. This allows the stirring wheel to intermittently agitate the ink in the tank, ensuring thorough mixing of various components such as resin, solvent, and additives, thereby guaranteeing the stability and performance of the ink. When the packaging printing process requires the ink, it can be promptly retrieved and used, effectively ensuring the printing efficiency of the packaging printing process. 2. When the teeth of the first drive gear mesh with the first drive rack, the stirring shaft and the stirring wheel rotate. In this state, the stirring shaft and the stirring wheel agitate the ink in the oil storage tank. When the teeth of the first drive gear disengage from the first drive rack and the smooth part gradually rotates to the position of the first drive rack, the stirring shaft and the stirring wheel gradually stop rotating. In this state, the stirring shaft and the stirring wheel gradually stop agitating the ink in the oil storage tank.

[0030] By dividing the first drive gear into a smooth part and a toothed part, the engagement between the first drive gear and the first drive rack can be set to be intermittent. This allows for appropriate stirring of the ink during prolonged storage, ensuring thorough mixing of its various components such as resin, solvent, and additives. This guarantees the stability and performance of the ink while effectively preventing over-stirring, which can cause temperature imbalances and affect its performance. Therefore, intermittent stirring ensures appropriate stirring of the ink while effectively avoiding over-stirring.

[0031] Intermittent stirring of the ink during long-term storage ensures its stability and performance, allowing it to be used promptly when needed, thus contributing to the stability of the packaging and printing process. 3. As the first drive gear and the first drive rack engage or disengage, during the process of the second wedge sliding to the left and resetting to the right in the second mounting box, the stirring shaft moves in two different states, clockwise and counterclockwise, which in turn drives the rotating shaft to move in two different states, clockwise and counterclockwise, which in turn drives the drive gear to rotate clockwise and counterclockwise, respectively.

[0032] When the drive gear rotates clockwise, it meshes only with the first bevel gear. In this state, the first bevel gear controls the heating box to heat the oil tank. When the drive gear rotates counterclockwise, it meshes only with the second bevel gear. In this state, the second bevel gear controls the cooling box to cool the oil tank. Thus, by having the drive gear rotate clockwise and counterclockwise, the temperature of the ink in the oil tank is adjusted. Attached Figure Description

Detailed Implementation

[0035] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.

[0036] Example: This application discloses a highly efficient printing process for packaging containers, including the following steps: S1. Lamination process: A transparent plastic film is applied to the surface of the printed material to protect the printing surface, enhance gloss, and prevent water and stains. S2. Varnishing process: A colorless and transparent coating is applied to the surface of the printed material to form a glossy layer, which enhances the gloss and provides protection. S3. Ink Control: The viscosity and drying speed of the ink are dynamically adjusted according to the paper type and ambient humidity. The ink is stirred in the corresponding oil storage tank 1. Stirring ensures that the various components such as resin, solvent and additives are fully mixed, thereby ensuring the stability and performance of the ink. S4. Die-cutting and creasing process: According to the design requirements, steel knives and steel wires are arranged into templates to cut the printed materials into specific shapes (die-cutting) or to press out lines that are easy to fold (creasing). S5, automated cutting.

[0037] Reference Figure 1 and Figure 2 The oil storage tank 1 is equipped with a stirring device, which includes a stirring shaft 2 and a stirring wheel 3. The stirring shaft 2 drives the stirring wheel 3 to stir the ink in the oil storage tank 1, ensuring that its various components, such as resin, solvent, and additives, are fully mixed, thereby ensuring the stability and performance of the ink. At the same time, the stirring shaft 2 is connected to an intermittent drive device, which is used to intermittently drive the stirring shaft 2 to rotate, thereby enabling the stirring wheel 3 to stir the ink in the oil storage tank 1.

[0038] When the ink in storage tank 1 is stored for an extended period, to prevent inconsistencies in pigment and concentration due to prolonged storage, the intermittent drive device can intermittently drive the stirring shaft 2 to rotate. This allows the stirring wheel 3 to intermittently agitate the ink in storage tank 1. Agitation ensures thorough mixing of various components such as resin, solvent, and additives, thereby guaranteeing the stability and performance of the ink. When the packaging printing process requires the ink, it can be readily accessed, effectively ensuring the printing efficiency of the packaging printing process.

[0039] Specifically, refer to Figure 1 and Figure 2 The intermittent drive device includes a first drive gear 4, a first drive rack 5, a second drive rack 6, and a second drive gear 7.

[0040] One side of the oil storage tank 1 is secured with a first mounting box 8 in the vertical direction by fastening bolts, and the bottom of the oil storage tank 1 is secured with a second mounting box 9 in the horizontal direction by fastening bolts. The first drive gear 4 and the first drive rack 5 are located inside the first mounting box 8, and the second drive rack 6 and the second drive gear 7 are located inside the second mounting box 9.

[0041] Specifically, the first drive gear 4 is driven by a corresponding motor, and the first drive rack 5 is vertically arranged and meshed with the first drive gear 4. During the rotation of the first drive gear 4 driven by the motor, the first drive rack 5 moves up and down in the vertical direction.

[0042] The second drive rack 6 is horizontally positioned and connected to the first drive rack 5. As the first drive rack 5 moves vertically up and down, it drives the second drive rack 6 to slide horizontally. The second drive gear 7 meshes with the second drive rack 6, and as the second drive rack 6 slides horizontally, it drives the second drive gear 7 to rotate.

[0043] Simultaneously, the bottom of the stirring shaft 2 extends downward into the second mounting box 9, and the second drive gear 7 is integrally fitted around the periphery of the stirring shaft 2. As the second drive gear 7 rotates, it synchronously drives the stirring shaft 2 to rotate, thereby driving the stirring wheel 3 to stir the ink in the oil storage tank 1.

[0044] Specifically, refer to Figure 1 and Figure 2 A first wedge 10 and a second wedge 11 are provided between the first drive rack 5 and the second drive rack 6. The first wedge 10 is located in the first mounting box 8 and is vertically arranged. The second wedge 11 is located in the second mounting box 9 and is horizontally arranged.

[0045] One end of the first wedge 10 is integrally connected to the first drive rack 5, the other end of the first wedge 10 is wedge-shaped and engaged with the second wedge 11, and the second drive rack 6 is integrally connected to the side wall of the second wedge 11.

[0046] Specifically, during the lifting and lowering process, the first drive rack 5 synchronously drives the first wedge block 10 to lift and lower. During the lifting and lowering process, the first wedge block 10 engages with the second wedge block 11 in a wedge shape, thereby driving the second wedge block 11 to slide horizontally. During the sliding process, the second wedge block 11 synchronously drives the second drive rack 6 to slide. During the sliding process, the second drive rack 6 meshes with the second drive gear 7, thereby driving the stirring shaft 2 and the stirring wheel 3 to rotate, so as to complete the stirring of the ink in the oil storage tank 1.

[0047] Furthermore, referring to Figure 1 , Figure 2 as well as Figure 3 The first drive gear 4 has a smooth part 12 and a toothed part 13 on its circumference, and the toothed part 13 is one-quarter of the circumference of the first drive gear 4.

[0048] When the teeth 13 of the first drive gear 4 mesh with the first drive rack 5, the stirring shaft 2 and the stirring wheel 3 rotate. In this state, the stirring shaft 2 and the stirring wheel 3 complete the stirring of the ink in the oil storage tank 1. When the teeth 13 of the first drive gear 4 disengage from the first drive rack 5 and the smooth part 12 gradually rotates to the position of the first drive rack 5, the stirring shaft 2 and the stirring wheel 3 gradually stop rotating. In this state, the stirring shaft 2 and the stirring wheel 3 gradually stop stirring the ink in the oil storage tank 1.

[0049] By dividing the first drive gear 4 into a smooth part 12 and a toothed part 13, the first drive gear 4 and the first drive rack 5 can be intermittently meshed. This allows for appropriate stirring of the ink during prolonged storage, ensuring thorough mixing of its various components such as resin, solvent, and additives. This guarantees the stability and performance of the ink while effectively preventing over-stirring, which can cause temperature imbalances and affect its performance. Therefore, intermittent stirring ensures appropriate stirring of the ink while effectively preventing over-stirring.

[0050] Intermittent stirring of the ink during long-term storage ensures its stability and performance, allowing it to be used promptly when needed, thus contributing to the stability of the packaging and printing process.

[0051] Furthermore, referring to Figure 1 and Figure 2 A lifting seat 14 is provided between the first drive rack 5 and the first wedge block 10. The upper and lower ends of the lifting seat 14 are integrally connected to the first drive rack 5 and the first wedge block 10, respectively. A fixed pulley 15 is provided inside the first mounting box 8. The lifting seat 14 is located on one side of the fixed pulley 15, and a counterweight 16 is provided on the other side of the fixed pulley 15. The lifting seat 14 and the counterweight 16 are connected by a traction belt wrapped around the periphery of the fixed pulley 15. The weight of the counterweight 16 is slightly greater than the weight of the lifting seat 14. In the initial state, the counterweight 16 is below and the lifting seat 14 is above.

[0052] When the first drive gear 4 and the first drive rack 5 mesh, the first drive rack 5 moves down and simultaneously drives the lifting seat 14 and the first wedge block 10 to move down. At this time, the counterweight block 16 is lifted. When the first drive gear 4 and the first drive rack 5 disengage, the counterweight block 16 moves down and lifts the lifting seat 14, which in turn drives the first drive rack 5 to rise until the first drive rack 5 is reset.

[0053] At the same time, refer to Figure 1 , Figure 2 as well as Figure 3A return spring 17 is provided horizontally inside the second mounting box 9. One end of the return spring 17 is connected to the inner wall of the second mounting box 9, and the other end of the return spring 17 is connected to the second wedge 11. When the first drive rack 5 is reset, the second wedge 11 is driven to reset synchronously through the return spring 17.

[0054] Furthermore, referring to Figure 1 and Figure 2 A rotating shaft 18 is vertically mounted inside the oil storage tank 1, and the rotating shaft 18 is integrally connected to the top of the stirring shaft 2. Meanwhile, a heating box 19 and a cooling box 20 are respectively installed on the left and right sides of the top of the oil storage tank 1. The stirring shaft 2 drives the rotating shaft 18 to rotate synchronously inside the oil storage tank 1, and during the rotation of the rotating shaft 18, it controls the heating box 19 or the cooling box 20 to regulate the temperature inside the oil storage tank 1.

[0055] The heating box 19 and cooling box 20 are controlled by the rotating shaft 18 to adjust the temperature inside the oil storage tank 1. This allows the ink in the oil storage tank 1 to be adjusted in temperature while being intermittently stirred, so that the ink is kept at a constant temperature. This helps to maintain the stability and performance of the ink during long-term storage.

[0056] Specifically, refer to Figure 1 , Figure 2 as well as Figure 4 A drive gear 21 is integrally connected to the circumference of the rotating shaft 18 in a horizontal direction, and the drive gear 21 is horizontally positioned. A first bevel gear 22 and a second bevel gear 23 are meshed and connected to the left and right sides of the drive gear 21, respectively, and both the first bevel gear 22 and the second bevel gear 23 are vertically positioned. The first bevel gear 22 is connected to the heating box 19, and the second bevel gear 23 is connected to the cooling box 20. As the drive gear 21 rotates with the rotating shaft 18, it meshes with either the first bevel gear 22 or the second bevel gear 23, thereby driving either the first bevel gear 22 or the second bevel gear 23 to rotate. The first bevel gear 22 controls the heating box 19 to raise the temperature of the oil storage tank 1, and the second bevel gear 23 controls the cooling box 20 to lower the temperature of the oil storage tank 1.

[0057] During the rotation of the first bevel gear 22, the heating box 19 is controlled to inject hot air into the oil storage tank 1 to raise the temperature of the oil storage tank 1; during the rotation of the second bevel gear 23, the cooling box 20 is controlled to inject cold air into the oil storage tank 1 to lower the temperature of the oil storage tank 1.

[0058] Reference Figure 1 , Figure 2 as well as Figure 4The first bevel gear 22 and the second bevel gear 23 are both connected horizontally at opposite ends by a rotating rod 24, and a rotating cam 25 is integrally fitted around the periphery of the rotating rod 24. Both the heating box 19 and the cooling box 20 are equipped with vent plates 26. A lifting rod 27 is provided between the vent plate 26 and the corresponding rotating cam 25. One end of the lifting rod 27 is connected to the vent plate 26, and the other end of the lifting rod 27 is connected to the rotating cam 25.

[0059] During the rotation of the first bevel gear 22 and the second bevel gear 23, the corresponding rotating rod 24 is driven to rotate synchronously. The rotating rod 24 drives its corresponding rotating cam 25 to rotate. During the rotation of the rotating cam 25, the lifting rod 27 is driven to rise and fall in the vertical direction. In turn, the lifting rod 27 drives the vent plate 26 to rise and fall in the corresponding heating box 19 or cooling box 20. During the rise and fall of the vent plate 26 in the heating box 19 or cooling box 20, the opening and closing of the heating box 19 or cooling box 20 is controlled.

[0060] Reference Figure 4 An auxiliary roller 28 is provided between the rotating cam 25 and the lifting rod 27, and the auxiliary roller 28 is sleeved around the lifting rod 27.

[0061] The auxiliary roller 28 helps to make the connection between the rotating cam 25 and the lifting rod 27 smoother, which in turn helps to ensure the stability of the rotating cam 25 driving the lifting rod 27 to rise and fall.

[0062] Furthermore, the circumference of the rotating cam 25 also has a smooth portion 12 and a toothed portion 13, the toothed portion 13 being one-quarter of the circumference of the rotating cam 25, and its toothed portion 13 being located between the first bevel gear 22 and the second bevel gear 23.

[0063] As the first drive gear 4 and the first drive rack 5 engage or disengage, and the second wedge 11 slides to the left and resets to the right within the second mounting box 9, the stirring shaft 2 moves in two different states: clockwise and counterclockwise. This causes the rotating shaft 18 to also move in two different states: clockwise and counterclockwise. Consequently, the rotating shaft 18 drives the drive gear 21 to rotate clockwise and counterclockwise, respectively.

[0064] When the drive gear 21 rotates clockwise, it meshes only with the first bevel gear 22. In this state, the first bevel gear 22 controls the heating box 19 to heat the oil storage tank 1. When the drive gear 21 rotates counterclockwise, it meshes only with the second bevel gear 23. In this state, the second bevel gear 23 controls the cooling box 20 to cool the oil storage tank 1. Thus, by having the drive gear 21 rotate clockwise and counterclockwise respectively, the temperature of the ink in the oil storage tank 1 is adjusted.

[0065] The implementation principle of the efficient printable packaging container printing process in this application embodiment is as follows: The oil storage tank 1 is equipped with a stirring device, which includes a stirring shaft 2 and a stirring wheel 3. The stirring shaft 2 drives the stirring wheel 3 to stir the ink in the oil storage tank 1, ensuring that its various components, such as resin, solvent, and additives, are fully mixed, thereby ensuring the stability and performance of the ink. At the same time, the stirring shaft 2 is connected to an intermittent drive device, which is used to intermittently drive the stirring shaft 2 to rotate, thereby enabling the stirring wheel 3 to stir the ink in the oil storage tank 1.

[0066] When the ink in storage tank 1 is stored for an extended period, to prevent inconsistencies in pigment and concentration due to prolonged storage, the intermittent drive device can intermittently drive the stirring shaft 2 to rotate. This allows the stirring wheel 3 to intermittently agitate the ink in storage tank 1. Agitation ensures thorough mixing of various components such as resin, solvent, and additives, thereby guaranteeing the stability and performance of the ink. When the packaging printing process requires the ink, it can be readily accessed, effectively ensuring the printing efficiency of the packaging printing process.

[0067] The first drive gear 4 has a smooth portion 12 and a toothed portion 13 on its circumference, with the toothed portion 13 being one-quarter of the circumference of the first drive gear 4.

[0068] When the teeth 13 of the first drive gear 4 mesh with the first drive rack 5, the stirring shaft 2 and the stirring wheel 3 rotate. In this state, the stirring shaft 2 and the stirring wheel 3 complete the stirring of the ink in the oil storage tank 1. When the teeth 13 of the first drive gear 4 disengage from the first drive rack 5 and the smooth part 12 gradually rotates to the position of the first drive rack 5, the stirring shaft 2 and the stirring wheel 3 gradually stop rotating. In this state, the stirring shaft 2 and the stirring wheel 3 gradually stop stirring the ink in the oil storage tank 1.

[0069] By dividing the first drive gear 4 into a smooth part 12 and a toothed part 13, the first drive gear 4 and the first drive rack 5 can be intermittently meshed. This allows for appropriate stirring of the ink during prolonged storage, ensuring thorough mixing of its various components such as resin, solvent, and additives. This guarantees the stability and performance of the ink while effectively preventing over-stirring, which can cause temperature imbalances and affect its performance. Therefore, intermittent stirring ensures appropriate stirring of the ink while effectively preventing over-stirring.

[0070] Intermittent stirring of the ink during long-term storage ensures its stability and performance, allowing it to be used promptly when needed, thus contributing to the stability of the packaging and printing process.

[0071] 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.
