Description

Technical Field

[0001] This utility model belongs to the field of nickel screen printing technology, specifically a continuous drying device for nickel screen printing. Background Technology

[0002] As the core carrier of high-precision printing processes in industries such as textiles, wallpaper, and metal foil, nickel screen printing has a surface with fine mesh holes. It is thin and fragile, and requires a drying process to remove the moisture from the paste adhering to it after printing, while ensuring the regularity of the mesh holes, the accuracy of the pattern, and the stability of the material.

[0003] Meanwhile, a cylindrical nickel mesh baking device for printing, with application number CN201721599296.9, includes a base, a box body, a box cover, a receiving plate, a drive system, and a control system. The box body is fixedly mounted on the base, and the control system is located inside the base. The box body and box cover are arc-shaped and coaxially arranged. The box body includes an inner shell, an outer shell, an end plate, and a heating tube. The heating tube is located within the cavity formed by the inner shell and the outer shell. The outer diameter of the outer shell is equal to the inner diameter of the box cover. The receiving plate is located at the lower edge of the box body. The drive system includes a gear, a rack, and a cylinder. The gear is located at the center of the outer wall of the end plate, and the box cover is connected to the gear via a connecting rod. The cylinder is located inside the base. The cylinder drives the rack to move up and down, the rack drives the gear to rotate, and the gear drives the connected box cover to rotate.

[0004] However, the following problems were found in the implementation of the relevant technology: the drying device is fixed. During the initial wetting period, if the heat source is too close and too strong, the moisture on the surface of the nickel mesh will evaporate quickly to form a "hard shell", which will block the internal moisture evaporation channel and cause the deep slurry to not dry. In the later stage of drying, if the heat source is too far away and the hot air energy is insufficient, the slurry cannot be completely solidified, or the drying time may need to be extended.

[0005] Therefore, we propose a continuous drying device for printed nickel mesh. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a continuous drying device for printed nickel mesh, which features the advantages of providing hot air through three sets of hot air blowers, and being able to control the distance between the air outlet and the mesh surface segment by segment to obtain different convection intensities. At the same time, it can adjust the tension of the conveyed printed nickel mesh to ensure flatness.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a continuous drying device for nickel mesh printing, comprising a support frame, three sets of hot air blowers fixedly connected to the upper surface of the support frame, a hot air pipe fixedly connected to the output end of each set of hot air blowers, an air outlet fixedly connected to the other end of the hot air pipe, sliders fixedly connected to both sides of each set of air outlets, three sets of sliding grooves provided inside the support frame, the sliders slidingly connected to the sliding grooves, a screw rotatably connected to the upper surface of the rear slider, three threaded holes provided on the support frame, the screw threadedly connected to the threaded holes, a motor fixedly connected to the inner surface of the support frame, a lead screw fixedly connected to the output end of the motor, a threaded block threadedly connected to the lead screw, a rotating shaft rotatably connected to the outer surface of the threaded block, and a tension roller fixedly connected to the outer surface of the rotating shaft.

[0008] Preferably, a control handle is fixedly connected to the upper surface of the screw, and the control handle is provided with anti-slip texture.

[0009] Preferably, the support frame is provided with three openings, the hot air pipe is movably connected to the openings, and a protective sleeve is fixedly connected to the openings.

[0010] Preferably, a protective shell is fixedly connected to the inner surface of the support frame, and the lead screw is located inside the protective shell.

[0011] Preferably, the protective shell is provided with a slot, and the tensioning roller is slidably connected to the slot.

[0012] Preferably, a fixing block is fixedly connected to the inner surface of the protective shell, and the fixing block is rotatably connected to the lead screw.

[0013] Preferably, a sliding rod is fixedly connected to the outer surface of the fixing block, and the threaded block is slidably connected to the sliding rod.

[0014] Preferably, a conveying roller is provided inside the support frame, and an observation window is provided on the front surface of the support frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model utilizes the cooperation of a hot air blower, a hot air pipe, an air nozzle, a slide groove, a slider, a screw, and a threaded hole. It provides hot air through three sets of hot air blowers, and the height of each air nozzle can be adjusted to control the distance between the air outlet and the mesh surface in stages. This allows for a gentler heating and moisture removal to the mesh in the initial stage, while increasing the hot air energy or reducing the distance in the later stage achieves stronger drying. This avoids single-point overheating that could cause burrs, localized stress concentration, and deformation on the nickel mesh surface. Furthermore, the adjustable distance in different areas allows for different convection intensities, enabling more even removal of moisture.

[0016] 2. This utility model can adjust the tension of the printed nickel screen by cooperating with the motor, lead screw, threaded block, rotating shaft and tension roller. Appropriate tension can maintain the flatness of the screen material along the entire transmission path, avoid the generation of excess slack area between the drive roller and the driven roller, thereby reducing the initial source of wrinkles and improving the flatness of the screen and the uniformity of the entire line.

[0022] Furthermore, the support frame 1 is provided with three openings, the hot air pipe 3 is movably connected to the openings, and a protective sleeve is fixedly connected to the openings to protect the hot air pipe 3 and reduce wear.

[0023] Furthermore, a protective shell 14 is fixedly connected to the inner surface of the support frame 1, and the lead screw 10 is located inside the protective shell 14 to protect the connection structure of the lead screw 10.

[0024] It is worth noting that the protective shell 14 is provided with a slot, and the tension roller 13 is slidably connected to the slot.

[0025] It is worth noting that a fixing block 15 is fixedly connected to the inner surface of the protective shell 14. The fixing block 15 is rotatably connected to the lead screw 10 and is used to support the lead screw 10.

The height of the air nozzles 4 at different positions can be adjusted, thereby adjusting the distance between the air nozzles 4 and the nickel screen being printed at different drying stages. By controlling the handle 17 to rotate the screw 7, the screw 7 rotates within the threaded hole 8. Simultaneously, the screw 7 moves due to the action of the thread, thereby driving the slider 6 to slide within the groove 5. The slider 6 then drives the air nozzles 4 to slide, adjusting the distance between the air nozzles 4 and the nickel screen being printed. Then, through... The conveyor roller 19 conveys the unfolded printing nickel screen, while the tension roller 13 presses down on the printing nickel screen to ensure tension. The tension can be adjusted by adjusting the pressure of the tension roller 13 on the printing nickel screen. The motor 9 drives the lead screw 10 to rotate, and the threaded block 11 moves linearly on the lead screw 10 through the action of the thread, so that the threaded block 11 slides on the lead screw 10. In turn, the threaded block 11 drives the rotating shaft 12 to slide with the tension roller 13. The height position of the tension roller 13 is adjusted, and the tension is adjusted by adjusting the pressure of the tension roller 13 on the printing nickel screen.
