Description

Technical Field

[0001] This utility model relates to the field of inkjet printer technology, and in particular to an air-cooled cooling mechanism for inkjet printers. Background Technology

[0002] Currently, inkjet printers are widely used in industrial production, packaging, and commercial office applications. Through non-contact inkjet technology, inkjet printers print text, patterns, codes, and other information onto the surface of various carrier materials, achieving visual marking of information.

[0003] A typical inkjet printer includes a printing section, a winding section, and a drying section. During the material processing, the inkjet printer sprays ink onto the material in a preset pattern shape through the printing section. At this time, the material is in a wet state. The drying section dries the printed material at high temperature, and the winding section winds up the dried material. Driven by the winding section, the material is wound into a roll, making it easy for operators to sort and remove the material.

[0004] Regarding the aforementioned technologies, the material remains at a high temperature after printing, making it prone to deformation. This causes the material to be flat on the inside and loose on the outside due to the winding tension during the winding process. After unfolding, wrinkles and curling edges appear, which is not conducive to improving the quality of the finished product. Utility Model Content

[0005] In order to improve the quality of finished products after printing by an inkjet printer, this application provides an air-cooled cooling mechanism for an inkjet printer.

[0006] This application provides an air-cooled cooling mechanism for an inkjet printer, employing the following technical solution: A cooling mechanism for an inkjet printer includes an inkjet printer body. The inkjet printer body has an external take-up wheel for pulling material. Inside the inkjet printer body, on the side furthest from the take-up wheel, is a drying chamber. The drying chamber has heating elements on both sides along its horizontal direction, arranged vertically. Several heating fans are located on both sides of the drying chamber, with the heating elements positioned between two sets of heating fans. Several support wheels are rotatably connected to the lower end of the drying chamber on the inkjet printer body. Printed material enters the drying chamber vertically downwards, wraps around the support wheels, and moves vertically upwards before being output from the upper end of the drying chamber. A cooling fan is located at the upper end of the drying chamber. A second cooling fan is located on the inkjet printer body, directly opposite the first cooling fan, and is positioned opposite the first cooling fan both when the material is output from the drying chamber and when it enters the drying chamber after printing.

[0007] By adopting the above technical solution, the inkjet printer body supports the take-up roller, which in turn takes up and supports the material. The inkjet printer body also supports and fixes the drying chamber. Two support rollers work together to support and guide the material, allowing it to be vertically transported within the drying chamber. The drying chamber supports the heating unit, which heats the air inside. Two cooling fans on both sides blow air into the drying chamber, accelerating the airflow and ensuring the material is heated evenly during transport. This improves the drying effect of the drying chamber. When the material is output from the drying chamber, cooling fan one immediately blows air onto the material, while cooling fan two directs the hot airflow from cooling fan one outwards, reducing the impact of surrounding hot air on the output material. The airflow direction of cooling fan one is parallel to the material transport direction, increasing the area of ​​the material being blown by cooling fan one, thus improving the blowing effect of cooling fan one. Together, they cool and dissipate heat, improving the cooling effect of the device and reducing the probability of material deformation during take-up, thereby improving the quality of the material produced by the device.

[0008] Optionally, the heating section includes several heating tubes and a protective plate. Both the heating tubes and the protective plate are arranged vertically. The two ends of the heating tubes along the vertical direction are respectively connected to the inner walls of the drying box on both sides along the vertical direction. Both the heating tubes and the protective plate are parallel to the material movement direction. The protective plate has a mounting groove adapted to the heating tubes along the vertical direction, and the heating tubes are located in the mounting grooves.

[0009] By adopting the above technical solution, the drying box supports and fixes the heating tube and the protective plate. The protective plate accommodates and limits the heating tube through the groove, reducing the probability of the material coming into contact with the heating tube during the transportation process. This helps to improve the heating stability of the drying box. The heating part heats the material evenly during the material transportation process, which helps to improve the heating effect of the drying box on the material.

[0010] Optionally, the upper end of the drying box is provided with a suction pipe, which is parallel to the axis of the support wheel. The suction pipe is located between the material output from the drying box and the material input to the drying box. A ventilation opening is provided on the suction pipe, and the side of the suction pipe away from the drying box is connected to an external fan.

[0011] By adopting the above technical solution, the drying box supports and fixes the suction pipe. During the heating process of the material, the suction pipe absorbs the evaporated water vapor through the vent under the action of the external fan. The water vapor enters the suction pipe through the vent, reducing the probability of the evaporated water vapor re-wetting the material, which is beneficial to improving the drying effect of the drying box on the material.

[0012] Optionally, the protective plate has several vents along its vertical direction for airflow.

[0013] By adopting the above technical solution, the heating fan blows hot airflow onto the material through the air vent, making the hot airflow evenly dispersed and thus ensuring that the material surface is evenly heated. At the same time, the holes balance the air pressure inside the drying chamber, which helps to improve the drying effect and working stability of the drying chamber.

[0014] Optionally, a probe is provided in the middle of the drying chamber, and the probe is parallel to the air suction pipe.

[0015] By adopting the above technical solution, the drying chamber supports and fixes the probe, and the probe separates the materials moving upward and downward, reducing the probability of ink adhesion and color transfer caused by the materials on both sides, which is beneficial to improving the drying effect of the materials.

[0016] Optionally, the bottom of the drying oven has multiple positioning holes on both sides along the horizontal direction that are adapted to the heating tubes, and the lower end of the heating tubes is inserted into the positioning holes and fits against the inner wall of the positioning holes.

[0017] By adopting the above technical solution, the heating tube is supported and fixed at the bottom of the drying oven through positioning holes, which further improves the installation stability of the heating tube, reduces the probability of the heating tube shaking during the heating process, and helps to improve the installation stability and working stability of the heating tube.

[0018] Optionally, the drying oven includes a box body and a door. The door is provided with fixing rods on both sides along the horizontal direction, and the box body is provided with fixing plates on both sides along the horizontal direction, which are directly opposite the fixing rods. The fixing plates are provided with fixing grooves that are adapted to the fixing rods along the thickness direction, and the fixing rods are inserted into the fixing grooves and fit against the bottom of the fixing grooves.

[0019] By adopting the above technical solution, the inkjet printer body supports the cabinet, the cabinet supports and fixes the fixing plate, the fixing plate supports and limits the fixing rod through the fixing groove, thereby supporting the cabinet door, which in turn allows the cabinet to support and fix the cabinet door. The cabinet is installed by inserting the fixing rod into the fixing groove. The operator can disassemble the cabinet door by moving the cabinet door upward to disengage the fixing rod from the fixing groove, thus improving the convenience of the operator in maintaining and repairing the drying oven.

[0020] Optionally, the inner wall of the fixing groove on the side away from the box body is set as an inclined surface, and the inclined surface is inclined in the direction from the box door to the box body.

[0021] By adopting the above technical solution, the fixing groove guides the fixing rod through the inclined surface, so that the fixing rod is inserted into the fixing groove or detached from the fixing groove along the inclined surface, thereby improving the convenience of installation and disassembly of the cabinet door.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The inkjet printer body supports the take-up roller, which in turn winds and supports the material. The inkjet printer body also supports and fixes the drying chamber. Two support rollers work together to support and guide the material, allowing it to be vertically transported within the drying chamber. The drying chamber supports the heating unit, which heats the air inside. Two cooling fans on both sides blow air into the drying chamber, accelerating the airflow and ensuring the material is heated evenly during transport. This improves the drying effect. When the material exits the drying chamber, cooling fan one immediately blows air onto the material, while cooling fan two directs the hot airflow from cooling fan one outwards, reducing the impact of surrounding hot air on the material. The airflow from cooling fan one is parallel to the material transport direction, increasing the area of ​​the material being blown by cooling fan one and thus improving the blowing effect of cooling fan one. Together, they cool and dissipate heat, improving the cooling effect of the device and reducing the probability of material deformation during winding, thereby improving the quality of the material produced by the device. 2. The drying oven supports and fixes the heating tubes and protective plates. The protective plates contain and limit the heating tubes through grooves, reducing the probability of material contact with the heating tubes during transportation. This helps improve the heating stability of the drying oven. The heating section heats the material evenly during transportation, which helps improve the heating effect of the drying oven on the material. 3. The drying chamber supports and fixes the suction pipe. During the heating process of the material, the suction pipe absorbs the evaporated water vapor through the vent under the action of the external fan. The water vapor enters the suction pipe through the vent, reducing the probability of the evaporated water vapor re-wetting the material, which helps to improve the drying effect of the drying chamber on the material.

Detailed Implementation

[0027] The present application will be further described in detail below with reference to all the accompanying drawings.

[0028] This application discloses an air-cooled cooling mechanism for an inkjet printer. Example

[0029] Reference Figure 1 and Figure 2 A cooling mechanism for an inkjet printer includes an inkjet printer body 1. A take-up roller 11 is installed on the outer wall of the inkjet printer body 1 to take up the material. A drying chamber 2 is installed inside the inkjet printer body 1 on the side away from the take-up roller 11. The upper end of the drying chamber 2 has a first through hole 211 and a second through hole 212 adapted to the width of the material. The first through hole 211 and the second through hole 212 are arranged laterally. The first through hole 211 is located on the side of the drying chamber 2 away from the take-up roller 11, and the second through hole 212 is located on the side of the drying chamber 2 closer to the take-up roller 11. The lower end of the drying chamber 2 has a third through hole 212 directly opposite the first through hole 211. 3. The inkjet printer body 1 is rotatably connected to two parallel support wheels 12 at the lower end of the drying chamber 2, and the two support wheels 12 are located between the through holes 3 213 and 4 214. Under the traction of the take-up wheel 11, the material enters the drying chamber 2 through the through hole 1 211 after printing, approaches the through hole 2 212 in the vertical direction and is output through the through hole 2 212. The material passes through the lower end of the support wheel 1 12 and rolls with the support wheel 1 12. The material enters the drying chamber 2 again through the through hole 4 214 and moves in the vertical direction and is output through the through hole 2 212.

[0030] Reference Figure 2 and Figure 3Heating units 23 are installed on both inner walls of the drying chamber 2, parallel to the material surface. Each heating unit 23 includes a heating pipe 231 and a protective plate 232. The heating pipe 231 is vertically oriented, and both sides of the heating pipe 231 are fixedly connected to the inner wall of the drying chamber 2 along its length. The drying chamber 2 supports and fixes the heating pipe 231 and the protective plate 232. The protective plate 232 is parallel to the heating pipe 231 and has multiple mounting slots 233 vertically oriented. The heating pipe 231 is located within the mounting slots 233 and does not protrude from the surface of the protective plate 232. The mounting slots 233 accommodate and limit the heating pipe 231, reducing the probability of contact between the material and the heating pipe 231 during material movement. The heating pipe 231 dries the material by heating air, and the protective plate 232 provides uniform heating of the air, ensuring uniform heating of the material during transport and improving the heating effect.

[0031] Reference Figure 1 and Figure 2 Multiple heating fans 24 are installed on both sides of the drying oven 2 near the heating tube 231, with each heating fan 24 corresponding to the other on both sides. Multiple air vents 251 are vertically opened along the upper edge of the protective plate 232. The air vents 251 have different shapes. When the heating fans 24 blow air, they blow the hot air in the drying oven 2 through the air vents 251 onto the material surface. The air vents 251 make the airflow in the drying oven 2 evenly dispersed, further making the material surface evenly heated, thereby improving the drying effect of the drying oven 2 on the material. At the same time, the air vents 251 balance the air pressure in the drying oven 2, which is conducive to improving the drying effect of the drying oven 2 on the material and the working stability of the drying oven 2.

[0032] Reference Figure 1 and Figure 2 The bottom of the drying chamber 2 has multiple positioning holes 27 on both sides along the length direction, which are adapted to the heating tube 231. The lower end of the heating tube 231 is inserted into the positioning hole 27. The drying chamber 2 positions and supports the heating tube 231 through the positioning hole 27, which reduces the probability of the heating tube 231 shaking due to vibration during the operation of the inkjet printer, and helps to improve the installation stability and working stability of the heating tube 231.

[0033] Reference Figure 1 and Figure 2 A cooling fan 3 is fixedly installed on the upper end of the drying box 2 near the take-up reel 11. A support wheel 13 is vertically connected to the inner wall of the box body 21 above the cooling fan 3. After the material is output through the through hole 212, it moves to the surface of the support wheel 13. The support wheel 13 supports and guides the material. After passing through the support wheel 13, the material is wound around the take-up reel 11.

[0034] Reference Figure 1 and Figure 2The material between support wheel 13 and the upper end of drying chamber 2 is directly opposite to cooling fan 3. Cooling fan 3 cools the material surface by blowing air. The airflow direction of cooling fan 3 is perpendicular to the material movement direction, thereby increasing the blowing area of ​​cooling fan 3 and further improving the cooling effect of cooling fan 3 on the material. Cooling fan 4 is installed on the inner wall of the inkjet printer near cooling fan 3. Cooling fan 3 and cooling fan 4 are directly opposite each other. Cooling fan 4 exhausts the hot air blown by cooling fan 3. Cooling fan 3 and cooling fan 4 work together to improve the efficiency of hot air exhaust, further improving the cooling effect on the material, thereby reducing the probability of material deformation during winding and improving the quality of the material produced by the device.

[0035] Reference Figure 1 and Figure 2 The upper part of the inner wall of the drying chamber 2 is equipped with a suction pipe 25. One end of the suction pipe 25 is connected to an external fan along its length. Multiple ventilation openings 234 are formed along the upper part of the suction pipe 25. The drying chamber 2 supports and fixes the suction pipe 25. When the suction pipe 25 is working, a small amount of water vapor generated by the drying process on the material floats upwards and enters the suction pipe 25 through the ventilation openings 234. The ventilation openings 234 are circular, facilitating the even entry of water vapor into the suction pipe 25 from all sides. This improves the suction effect of the suction pipe 25 on water vapor, thereby reducing the probability of secondary wetting of the material by water vapor and improving the drying effect of the drying chamber 2. A probe 26 is installed on the inner wall of the drying chamber at the lower end of the suction pipe 25. The probe 26 isolates the material on both sides, reducing the probability of ink adhesion and color transfer caused by materials coming close together, further improving the drying effect of the drying chamber 2.

[0036] Reference Figure 1 and Figure 2 The drying oven 2 includes a body 21 and a door 22. Fixing rods 221 are fixedly installed on both sides of the door 22 along its width. Fixing plates 215, corresponding to the fixing rods 221, are fixedly installed on both sides of the body 21 along its transverse direction. The body 21 supports the fixing plates 215. A fixing groove 216 is vertically formed on the upper edge of the fixing plate 215. The fixing rods 221 are inserted into the fixing groove 216 and fit against the inner wall of the fixing groove 216. The fixing plates 215 are fixed through the fixing groove 216. The rod 221 provides support and limits, thereby enabling the box body 21 to support and limit the box door 22. The operator can install the box door 22 by moving the box door 22 vertically downward to insert the fixing rod 221 into the fixing groove 216, and disassemble the box door 22 by moving the box door 22 vertically upward to disengage the fixing rod 221 from the fixing groove 216. This improves the stability of the installation and disassembly of the box door 22 and facilitates the operator to maintain and repair the inside of the box body 21.

[0037] Reference Figure 1 and Figure 2 The inner wall of the fixing groove 216 on the side away from the box body 21 is set as an inclined surface. The inclined surface is inclined from the box door 22 towards the box body 21. When the fixing rod 221 is inserted into the fixing groove 216, the inclined surface guides and supports the fixing rod 221, which helps to improve the stability of the box door 22 installation and the convenience of disassembly.

[0038] The implementation principle of the air-cooled cooling mechanism for a printer according to an embodiment of this application is as follows: The printer body 1 supports the drying chamber 2 and the take-up roller 11. Under the traction of the take-up roller 11, the drying chamber 2 supports the heating part 23. The heating part 23 heats the air in the drying chamber 2, thereby uniformly heating the material. The heating fan 24 blows air to make the material surface fully contact the hot air, further improving the drying effect of the drying chamber 2 on the material. The cooling fan 3 blows the material output from the through hole 212 to cool it down in real time. The cooling fan 4 exhausts the hot air blown by the cooling fan 3, reducing the probability that the hot air will affect the drying of the material. The cooling fan 3 and the cooling fan 4 work together to cool the material surface, reducing the probability of the material warping and deformation when it is wound by the take-up roller 11, thereby improving the quality of the material produced by the device.

[0039] 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.
