Description

Technical Field

[0001] This application relates to the field of printing equipment, and in particular to a drying structure for use in water-based ink printing equipment and a water-based ink printer. Background Technology

[0002] A water-based ink printer is a type of printer that uses water-based ink as its printing pigment. Compared to traditional inkjet or laser printers, water-based ink printers use water-based ink pigments, which typically means that they use water-based inks.

[0003] In related technologies, the drying time and adhesion of this type of water-based ink on the workpiece are different from those of traditional ink. Therefore, water-based ink printers are often equipped with corresponding ovens to bake the water-based ink on the workpiece, so as to effectively improve the efficiency of drying and shaping of the water-based ink on the workpiece.

[0004] However, the drying ovens in most water-based ink printers do not dry the ink on the workpiece evenly enough. This results in inconsistent drying speeds, causing some areas of the ink to dry too quickly while others dry too slowly. This affects the overall print quality and is detrimental to the daily use of water-based ink printers.

[0005] In addition, during the high-temperature drying process, a large amount of oil fumes will be generated on the surface of the workpiece. If they are not absorbed in time, the ink will accumulate in the equipment and form grease. If the printer is used for a long time, the grease will drip down and affect the workpiece during transmission. Summary of the Invention

[0006] This application provides a drying structure for water-based ink printing equipment and a water-based ink printer. The purpose is to effectively ensure that when a workpiece is printed on the water-based ink printer, the drying structure on the water-based ink printer can uniformly dry the water-based ink on the workpiece, so that the water-based ink on the workpiece can be dried and set synchronously and uniformly, thereby helping to ensure the overall printing quality of the workpiece and facilitating the daily use of the water-based ink printer.

[0007] At the same time, a large amount of oil fumes generated on the surface of the workpiece will be discharged to the outside, thereby effectively preventing the oil fumes from affecting the workpiece during transmission.

[0008] This application provides a drying structure for water-based ink printing equipment, employing the following technical solution: A drying structure for use in water-based ink printing equipment. It includes an oven and a cooling box arranged sequentially along the workpiece conveying direction, the oven and the cooling box being connected, and the oven being used to heat and dry the water-based ink on the workpiece; The oven is equipped with a heating assembly for heating the printing surface of the workpiece. The heating assembly consists of multiple heating elements, which are arranged alternately along the conveying direction of the workpiece, and the spacing between two adjacent heating elements gradually increases along the conveying direction of the workpiece. The oven is equipped with a fume extraction component for absorbing oil fumes.

[0009] By adopting the above technical solution, this distribution method can effectively avoid the heating elements in two adjacent heating components being distributed side by side, thereby effectively avoiding the problem of excessively high overall temperature in the oven caused by the side-by-side distribution of heating elements; at the same time, the staggered distribution of heating elements in two adjacent heating components can make the heat emitted by the heating elements more uniform, which is conducive to the uniform drying of water-based ink on the workpiece or material, and can make the water-based ink on the workpiece or material dry and set synchronously and evenly, thus helping to ensure the overall printing quality of the workpiece or material and facilitating the daily use of the water-based ink printer.

[0010] Meanwhile, since the heat continuously emitted by the heating elements eventually settles at the top of the oven, the temperature of the heating elements closer to the top is higher, while the temperature of the heating elements closer to the bottom is lower, creating a temperature difference. By arranging the heating elements from bottom to top with the spacing between adjacent elements gradually increasing, the heating elements closer to the bottom have a higher density and heat up faster, while those closer to the top have a lower density and heat up more slowly. This distribution method balances and compensates for the temperature difference between these heating elements, effectively reducing the temperature difference between adjacent elements and ensuring more uniform heat dissipation within the oven. This, in turn, facilitates the simultaneous and even drying and setting of the ink on the workpiece within the oven.

[0011] At the same time, the fume extraction component can effectively exhaust the oil fumes generated by the ink in the oven to the outside of the oven, thereby effectively preventing the oil fumes from affecting the workpieces during transmission.

[0012] Preferably, an exhaust pipe is installed on the top of the cooling box, and two suction pipes are installed on the side wall of the drying oven, both of which are connected to the exhaust pipe. The smoke extraction assembly includes a first smoke exhaust pipe and a smoke exhaust plate, and the two air intake pipes are respectively connected to the first smoke exhaust pipe and the smoke exhaust plate; The first exhaust pipe and the exhaust plate are both installed horizontally on the top of the oven. The first exhaust pipe and the exhaust plate are used to exhaust the oil fumes inside the oven to the outside of the oven.

[0013] By adopting the above technical solution, the ink on the workpiece will generate a certain amount of oil fumes after baking. When the workpiece is baked in the oven, the exhaust pipe is opened and the exhaust pipe will draw in air. The air drawn in enters the first exhaust pipe and exhaust plate through the exhaust pipe. The oil fumes generated by the ink on the workpiece are carried to the first exhaust pipe and exhaust plate by the air drawn in through the exhaust pipe and the exhaust pipe, and flow to the exhaust pipe through the first exhaust pipe and exhaust plate. Finally, the oil fumes generated by the ink during baking are discharged outside the oven through the exhaust pipe.

[0014] Preferably, the first exhaust pipe has multiple exhaust holes evenly spaced along its length on both its left and right sides; the exhaust plate also has multiple exhaust holes evenly spaced along its length on its sidewall. Furthermore, the closer the exhaust holes on the first exhaust pipe and the exhaust plate are to the air intake pipe, the smaller their diameter.

[0015] By adopting the above technical solution, the oil fumes generated by the ink on the workpiece are drawn in by the air from the exhaust pipe and the suction pipe and carried to the first exhaust pipe and the exhaust plate. They then flow to the exhaust pipe through the exhaust holes on the first exhaust pipe and the exhaust plate. Finally, the oil fumes generated by the ink during baking are discharged outside the oven through the exhaust pipe.

[0016] After the exhaust duct is opened, outside air enters the first exhaust duct and exhaust plate from the intake duct. Therefore, the closer the first exhaust duct and exhaust plate are to the intake duct, the greater the airflow and the larger the volume of air coming in from the intake duct. Therefore, in order to effectively ensure that the airflow at these exhaust holes on the first exhaust duct and exhaust plate remains uniform, the diameter of the exhaust holes closer to the intake duct is gradually reduced.

[0017] At the same time, the air drawn in from the suction pipe will cool down the heating element. The diameter of the exhaust hole gradually decreases as it gets closer to the suction pipe, so that the air discharged from the exhaust hole can cool down the heating element evenly, effectively reducing the temperature difference between the left and right ends of the heating element, which helps to further ensure more uniform heat distribution in the oven.

[0018] Preferably, a first ink receiving plate is provided on both the left and right sides of the bottom of the first exhaust pipe, and the end of the first ink receiving plate away from the first exhaust pipe is inclined upward. A second ink receiving plate is provided directly below the bottom of the first exhaust pipe along its length. Multiple ink discharge pipes are installed on the second ink receiving plate in the vertical direction. The multiple ink discharge pipes are evenly spaced along the length of the second ink receiving plate, and the top of the ink discharge pipes is connected to the second ink receiving plate. The bottom of the oven is inclinedly provided with a third ink receiving plate, which is connected to the bottom of the ink discharge pipe, and the lower side of the third ink receiving plate is connected to an ink discharge port.

[0019] By adopting the above technical solution, when the workpiece is running in the oven, the ink on the workpiece will often drip into the oven. When the workpiece is running, these dripping ink drops may smear on the workpiece, thus affecting the printing quality of the workpiece.

[0020] By adding a first ink receiving plate, a second ink receiving plate, an ink exhaust pipe, and a third ink receiving plate inside the oven, the ink dripping from the workpiece can be caught, thus effectively preventing the dripping ink from affecting the printing quality of the workpiece.

[0021] Specifically, when the workpiece reaches the top of the oven, the ink droplets on it fall onto the first ink receiving plate. When the ink on the first ink receiving plate accumulates to a certain amount, it flows to the second ink receiving plate, then through the second ink receiving plate into the ink discharge pipe, and continues to be discharged through the ink discharge pipe into the third ink receiving plate. Finally, the ink is guided through the third ink receiving plate to the ink discharge port at the bottom of the oven, and discharged out of the oven through the ink discharge port.

[0022] Preferably, the smoke extraction assembly further includes a second smoke exhaust pipe, which is installed horizontally on the top of the cooling box; The second exhaust pipe also has multiple exhaust holes on its left and right sides, and the second exhaust pipe is connected to the exhaust pipe. The bottom of the second exhaust pipe has a fourth ink receiving plate extending from the left and right sides towards each other.

[0023] By adopting the above technical solution, a second exhaust pipe is added inside the cooling box, which enables secondary exhaust of the oil fumes inside the cooling box, further ensuring the effectiveness of oil fume removal. Simultaneously, when the workpiece enters the cooling box, the fourth ink receiving plate can also collect the ink inside, effectively preventing ink drips from the workpiece into the cooling box.

[0024] Preferably, the cooling box is equipped with conveyor rollers for driving the workpiece. Cooling plates are provided on both the left and right sides of the cooling box, and a cooling air duct is formed between the cooling plates and the cooling box. The cooling plate includes a first plate and a second plate. One side of the first plate is connected to the outer wall of the second exhaust pipe, and the other side of the first plate is connected to the second plate. The cooling air duct is formed between the second plate and the cooling box.

[0025] By adopting the above technical solution, when the exhaust pipe is opened, cold air from the outside can enter the cooling box through the cooling air duct, and then cool down the double-row rollers in the cooling box through the cold air.

[0026] Preferably, the sidewall of the first plate has a groove along its width direction, and the sidewall of the second plate has a hole along its width direction, with fastening bolts inserted vertically in the groove and the hole.

[0027] By adopting the above technical solution, the second plate can be slidably installed on the first plate in the horizontal direction using the sliding groove and sliding hole.

[0028] When the position of the second plate needs to be adjusted, remove the fastening bolts from the groove and the sliding hole, then adjust the position of the second plate. After the position of the second plate is adjusted, insert the fastening bolts back into the groove and the sliding hole.

[0029] By setting the second plate to a sliding installation method, the distance between the second plate and the outermost insulation pipe can be adjusted, which in turn allows for adjustment of the size of the cooling air duct. This enables the adjustment of the air intake at the cooling air duct according to the actual operating conditions, making the drying structure more adaptable to different application scenarios and more convenient to use.

[0030] Preferably, the heating element is an infrared lamp.

[0031] By adopting the above technical solution, infrared lamp heating is achieved through light radiation. Compared with traditional resistance wire heating, light radiation heating is gentler and produces softer workpieces.

[0032] Preferably, a plurality of elastic clamps are fitted around the periphery of the heating element, and the plurality of elastic clamps are evenly distributed at intervals along the length direction of the heating element.

[0033] By adopting the above technical solution, the oven will vibrate during the transfer process, which will cause the heating element inside the oven to break due to the vibration. By placing elastic clamps around the heating element, the elastic clamps can play a good buffering role when the heating element vibrates, thereby effectively preventing the heating element from breaking during the transfer of the oven.

[0034] A water-based ink printer, The system includes an integrated machine and the aforementioned drying structure, wherein both the drying oven and the cooling box are installed inside the integrated machine.

[0035] By adopting the above technical solution, the drying oven and cooling box are installed inside the printer's all-in-one unit, which can effectively ensure the drying effect of water and ink on the workpiece during printing, and at the same time, cool down the double-row rollers in the cooling box, thus helping to ensure the printing quality of the workpiece.

[0036] In summary, this application includes at least one of the following beneficial technical effects: 1. This distribution method effectively avoids the heating elements in adjacent heating components being arranged side by side, thus preventing the overall temperature inside the oven from becoming too high due to the side-by-side arrangement of heating elements. At the same time, the staggered distribution of heating elements in adjacent heating components allows for more uniform heat dissipation, which is beneficial for the even drying of the ink on the workpiece or material. This ensures that the ink on the workpiece or material is dried and set synchronously and evenly, thereby ensuring the overall printing quality of the workpiece or material and facilitating the daily use of the inkjet printer.

[0037] Meanwhile, since the heat continuously emitted by the heating elements eventually settles at the top of the oven, the temperature of the heating elements closer to the top is higher, while the temperature of the heating elements closer to the bottom is lower, creating a temperature difference. By arranging the heating elements from bottom to top with the spacing between adjacent elements gradually increasing, the heating elements closer to the bottom of the oven have a higher density and heat up faster, while the heating elements closer to the top have a lower density and heat up more slowly. This distribution method can balance and compensate for the temperature difference between these heating elements, effectively reducing the temperature difference between adjacent heating elements and ensuring more uniform heat dissipation within the oven. This, in turn, facilitates the simultaneous and uniform drying and setting of the ink on the workpiece within the oven. 2. Adding a first ink receiving plate, a second ink receiving plate, an ink exhaust pipe, and a third ink receiving plate inside the oven can catch the ink dripping from the workpiece, thereby effectively preventing the dripping ink from affecting the printing quality of the workpiece. 3. The second plate can be slidably mounted on the first plate in a horizontal direction using the sliding groove and sliding hole; When the position of the second plate needs to be adjusted, remove the fastening bolts from the groove and the sliding hole, then adjust the position of the second plate. After the position of the second plate is adjusted, insert the fastening bolts back into the groove and the sliding hole. Attached Figure Description

[0040] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail below.

[0041] Example: This application discloses a drying structure for use in water-based ink printing equipment, referring to... Figure 1 The system includes an oven 1 and a cooling box 2 arranged sequentially along the workpiece conveying direction. The cooling box 2 is installed on top of the oven 1, and the oven 1 and the cooling box 2 are connected. The oven 1 is equipped with a heating component for heating the printing surface of the workpiece. When the printed workpiece passes through the oven 1, the heating component in the oven 1 heats and dries the ink on the workpiece. The oven 1 is also equipped with a fume extraction component for absorbing oil fumes; The cooling box 2 is equipped with double-row rollers for driving the workpiece. When the oven 1 is used for a long time, the heat dissipated by the heating components in the oven 1 will heat the double-row rollers in the cooling box 2. After the workpiece carrying water ink passes through the heated double-row rollers, the water ink on the workpiece will be detached. The cooling box 2 will cool down the double-row rollers to effectively prevent the water ink on the workpiece from detaching when it passes through the double-row rollers.

[0042] Specifically, refer to Figure 1 and Figure 2 The oven 1 is hollow inside. The oven 1 is equipped with multiple heating components. The multiple heating components are evenly distributed along the width of the oven 1. Each heating component consists of multiple heating elements 3. The heating elements 3 are installed in the oven in the horizontal direction, and these heating elements 3 in each heating component are distributed along the height of the oven 1.

[0043] Specifically, the heating elements 3 in adjacent heating components are staggered vertically. This distribution effectively avoids the heating elements 3 in adjacent heating components being arranged side by side, thus preventing the overall temperature inside the oven 1 from becoming too high due to the side-by-side arrangement of the heating elements 3. At the same time, the staggered vertical arrangement of the heating elements 3 in adjacent heating components makes the heat emitted by the heating elements 3 more uniform, which is conducive to the uniform drying of the ink on the workpiece or material. This allows the ink on the workpiece or material to be dried and set synchronously and uniformly, which helps to ensure the overall printing quality of the workpiece or material and facilitates the daily use of the inkjet printer.

[0044] Meanwhile, within each heating assembly, the spacing between adjacent heating elements 3 gradually increases along the workpiece conveying direction. Since the heat continuously emitted by the heating elements 3 eventually settles at the top of the oven 1, the temperature of the heating elements 3 closer to the top of the oven 1 is higher, while the temperature of the heating elements 3 closer to the bottom of the oven 1 is lower, creating a temperature difference. By gradually increasing the spacing between adjacent heating elements 3 from bottom to top, the heating elements 3 closer to the bottom of the oven 1 have a higher density and heat up faster, while the heating elements 3 closer to the top of the oven 1 have a lower density and heat up slower. This distribution method can balance and compensate for the temperature difference between these heating elements 3, effectively reducing the temperature difference between adjacent heating elements 3, and further ensuring that the heat emitted by these heating elements 3 within the oven 1 is more uniform. This is beneficial for the synchronous and uniform drying and setting of the ink on the workpiece within the oven 1.

[0045] In this embodiment, the heating element 3 is an infrared lamp tube. Infrared lamp tube heating is achieved through light radiation. Compared with traditional resistance wire heating, light radiation heating is gentler, and the heated workpiece is more flexible.

[0046] Furthermore, referring to Figure 1 and Figure 2 When the heating element 3 is installed inside the oven 1, its left and right ends are first installed on the oven 1. Simultaneously, multiple elastic clamps 19 are fitted around the heating element 3, evenly distributed along its length. During transport, the oven 1 vibrates, which can cause the heating element 3 inside to break. The elastic clamps 19, by providing cushioning during vibration, effectively prevent breakage of the heating element 3 during transport.

[0047] In this embodiment, insulation layers are added to both the inner and outer sides of the oven 1 to maintain the temperature inside the oven 1, thereby effectively ensuring the temperature inside the oven 1.

[0048] Specifically, the insulation layer inside the oven 1 consists of a cuboid plate and a cavity formed between the plate and the inner wall of the oven 1, and the cavity is filled with insulation cotton; the insulation layer outside the oven 1 consists of insulation tubes, which are cuboid tubes with hollow interiors, and insulation cotton is also filled inside the insulation tubes.

[0049] Meanwhile, an inspection window is hinged to the outside of the oven 1. When it is necessary to perform maintenance on the inside of the oven 1, the inspection window can be opened to facilitate the maintenance of the oven 1 by the staff.

[0050] Furthermore, referring to Figure 1 and Figure 2 The top of the cooling box 2 is equipped with an exhaust pipe 4, one end of which extends into the cooling box 2. Two suction pipes 5 are installed on the side wall of the drying oven 1, both of which are connected to the exhaust pipe 4. At the same time, a first exhaust pipe 6 and an exhaust plate 7 are installed along the length of the drying oven 1, and the two suction pipes 5 installed on the side wall of the drying oven 1 are connected to the first exhaust pipe 6 and the exhaust plate 7, respectively.

[0051] The ink on the workpiece will produce some oil fumes after baking. When the workpiece is baked in the oven 1, the exhaust pipe 4 is opened and the exhaust pipe 4 will draw in air. The air drawn in enters the first exhaust pipe 6 and exhaust plate 7 through the exhaust pipe 5. The oil fumes generated by the ink on the workpiece are carried by the air drawn in by the exhaust pipe 4 and the exhaust pipe 5 to the first exhaust pipe 6 and exhaust plate 7, and then flow to the exhaust pipe 4 through the first exhaust pipe 6 and exhaust plate 7. Finally, the oil fumes generated by the ink during baking are discharged to the outside of the oven 1 through the exhaust pipe 4.

[0052] Specifically, refer to Figure 1 , Figure 2 as well as Figure 3 The first exhaust pipe 6 has a triangular structure, with multiple round exhaust holes 8 evenly spaced along its length on both its left and right sides. The exhaust plate 7 is a bent plate that forms an exhaust chamber with the inner wall of the oven 1. The side walls of the exhaust plate 7 also have multiple exhaust holes 8 evenly spaced along its length. The oil fumes generated by the ink on the workpiece are drawn into the first exhaust pipe 6 and the exhaust plate 7 by the air drawn in by the exhaust pipe 4 and the suction pipe 5. The fumes then flow through the exhaust holes 8 on the first exhaust pipe 6 and the exhaust plate 7 to the exhaust pipe 4. Finally, the oil fumes generated by the ink during baking are discharged outside the oven 1 through the exhaust pipe 4.

[0053] In this embodiment, the closer these exhaust holes 8 on the first exhaust pipe 6 and the exhaust plate 7 are to the air suction pipe 5, the smaller their aperture is. After the air extraction pipe 4 is opened, external air enters the first exhaust pipe 6 and the exhaust plate 7 from the air suction pipe 5. Therefore, the closer the positions of the first exhaust pipe 6 and the exhaust plate 7 are to the air suction pipe 5, the greater the wind force and the larger the air volume coming from the air suction pipe 5. Thus, to effectively ensure that the wind force at these exhaust holes 8 on the first exhaust pipe 6 and the exhaust plate 7 remains uniform, the aperture of the exhaust holes 8 is gradually reduced as their position gets closer to the air suction pipe 5.

[0054] At the same time, the wind sucked in from the air suction pipe 5 will cool the heating element 3. By gradually reducing the aperture of the exhaust holes 8 as their position gets closer to the air suction pipe 5, the wind discharged from the exhaust holes 8 can uniformly cool the heating element 3, effectively reducing the temperature difference between the left and right ends of the heating element 3, which is conducive to further ensuring more uniform heat in the oven 1.

[0055] Further, with reference to Figure 1 , Figure 2 and Figure 3 , first ink receiving plates 9 are integrally formed on both left and right sides of the bottom of the first exhaust pipe 6. The first ink receiving plates 9 are in the shape of a rectangular plate, and one end of each first ink receiving plate 9 far away from the first exhaust pipe 6 is arranged to tilt upward. A second ink receiving plate 10 is additionally arranged directly below the bottom of the first exhaust pipe 6 along its length direction. The second ink receiving plate 10 is in a U-shaped structure. A plurality of ink discharge pipes 11 are installed on the second ink receiving plate 10 in the vertical direction. These ink discharge pipes 11 are evenly arranged at intervals along the length direction of the second ink receiving plate 10, and the top of each ink discharge pipe 11 is in communication with the second ink receiving plate 10. At the same time, a third ink receiving plate 12 is obliquely arranged at the bottom of the oven 1. The third ink receiving plate 12 is in communication with the bottom of the ink discharge pipe 11, and the lower side of the third ink receiving plate 12 is connected with an ink discharge port.

[0056] When the workpiece runs in the oven 1, the water-based ink on the workpiece often drips into the oven 1. When the workpiece is running, these dripping water-based inks are likely to smear on the workpiece, thus affecting the printing quality of the workpiece.

[0057] By additionally arranging the first ink receiving plate 9, the second ink receiving plate 10, the ink discharge pipe 11 and the third ink receiving plate 12 in the oven 1, the ink dripping from the workpiece can be caught, thereby effectively preventing the dripping ink from affecting the printing quality of the workpiece.

[0058] Specifically, when the workpiece runs to the top of the oven 1, the water-based ink on it drips onto the first ink receiving plate 9. When the ink on the first ink receiving plate 9 accumulates to a certain amount, it flows to the second ink receiving plate 10, then flows through the second ink receiving plate 10 into the ink discharge pipe 11, is further discharged from the ink discharge pipe 11 into the third ink receiving plate 12, and finally the ink is guided by the third ink receiving plate 12 to the ink discharge port at the bottom of the oven 1, and is discharged out of the oven 1 through the ink discharge port.

[0059] Furthermore, referring to Figure 1 , Figure 2 as well as Figure 3 A second exhaust pipe 13 is provided inside the cooling box 2 along its length. Multiple exhaust holes 8 are also provided on the left and right sides of the second exhaust pipe 13. The second exhaust pipe 13 is connected to the exhaust pipe 4. At the same time, a fourth ink receiving plate 14 is formed on the left and right sides of the bottom of the second exhaust pipe 13 in a direction that approaches each other. The fourth ink receiving plate 14 has an "L" shaped structure.

[0060] A second exhaust pipe 13 is added inside the cooling box 2 to perform secondary exhaust of the oil fumes inside the cooling box 2, further ensuring the effectiveness of oil fume removal. At the same time, when the workpiece moves into the cooling box 2, the fourth ink receiving plate 14 can also receive the ink inside the cooling box 2, thereby effectively preventing ink drips from the workpiece into the cooling box 2.

[0061] Furthermore, referring to Figure 1 and Figure 4 Cooling plates 15 are provided on both the left and right sides of the cooling box 2. A cooling air duct 16 is formed between the cooling plates 15 and the cooling box 2. When the exhaust pipe 4 is opened, cold air from the outside can enter the cooling box 2 through the cooling air duct 16, and then cool down the double-row rollers in the cooling box 2 through the cold air.

[0062] Specifically, refer to Figure 2 and Figure 4 The cooling plate 15 includes a first plate 151 and a second plate 152. The first plate 151 is formed by bending multiple rectangular plates together. One side of the first plate 151 is connected to the outer wall of the second exhaust pipe 13 by fastening bolts, and the other side of the first plate 151 is connected to the second plate 152. A certain space is reserved between the second plate 152 and the cooling box 2, which is the cooling air duct 16.

[0063] Meanwhile, in this embodiment, the second plate 152 is slidably disposed on the first plate 151 in the horizontal direction.

[0064] By setting the second plate 152 to a sliding installation method, the distance between the second plate 152 and the outermost insulation pipe can be adjusted, which in turn can adjust the size of the cooling air duct 16. This allows the air intake at the cooling air duct 16 to be adjusted according to the actual operating conditions, making the drying structure more adaptable to different application scenarios and more convenient to use.

[0065] Specifically, refer to Figure 4 and Figure 5The side wall of the first plate 151 is provided with a long strip groove 17 along its width direction, and the side wall of the second plate 152 is also provided with an elliptical sliding hole 18 along its width direction. Fastening bolts are inserted vertically in the groove 17 and the sliding hole 18.

[0066] When the position of the second plate 152 needs to be adjusted, remove the fastening bolts from the slide groove 17 and slide hole 18, then adjust the position of the second plate 152. After the position of the second plate 152 is adjusted, insert the fastening bolts back into the slide groove 17 and slide hole 18.

[0067] In this embodiment, multiple sliding grooves 17 and sliding holes 18 are provided, and they correspond one-to-one. By providing multiple sliding grooves 17 and sliding holes 18, the first plate 151 and the second plate 152 can be connected by multiple fastening bolts, thereby effectively enhancing the stability of the connection between the first plate 151 and the second plate 152.

[0068] Reference Figure 1 and Figure 6 This application also discloses a water-based ink printer, including the oven 1, cooling box 2 and all-in-one machine 20 described above, with the oven 1 and cooling box 2 both installed inside the all-in-one machine 20.

[0069] The drying structure applied to a water-based ink printing device and the implementation principle of the water-based ink printer in this application embodiment are as follows: The heating elements 3 in adjacent heating components are staggered vertically. This distribution effectively avoids the heating elements 3 in adjacent heating components being arranged side by side, thus preventing the overall temperature inside the oven 1 from becoming too high due to the side-by-side arrangement of the heating elements 3. At the same time, the staggered vertical distribution of the heating elements 3 in adjacent heating components makes the heat emitted by the heating elements 3 more uniform, which is conducive to the uniform drying of the ink on the workpiece or material. This allows the ink on the workpiece or material to be dried and set synchronously and evenly, which helps to ensure the overall printing quality of the workpiece or material and facilitates the daily use of the inkjet printer.

[0070] Meanwhile, within each heating assembly, the spacing between adjacent heating elements 3 gradually increases from bottom to top. Since the heat continuously emitted by the heating elements 3 eventually settles at the top of the oven 1, the temperature of the heating elements 3 closer to the top of the oven 1 is higher, while the temperature of the heating elements 3 closer to the bottom of the oven 1 is lower, creating a temperature difference. By distributing these heating elements 3 from bottom to top with gradually increasing spacing, the heating elements 3 closer to the bottom of the oven 1 have a higher density and heat up faster, while the heating elements closer to the top of the oven 1 have a lower density and heat up slower. This distribution method can balance and compensate for the temperature difference between these heating elements 3, effectively reducing the temperature difference between adjacent heating elements 3, and further ensuring that the heat emitted by these heating elements 3 within the oven 1 is more uniform. This is beneficial for the synchronous and uniform drying and setting of the ink on the workpiece within the oven 1.

[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.
