Abstract
Description
Technical Field
[0001] This application relates to the field of printing presses, and more particularly to a printhead moisturizing device for printing presses. Background Technology
[0002] A printing press is a widely used printing device that can spray different colors onto materials such as paper and plastic film to form patterns.
[0003] Existing printing presses include a machine body, a brush head, and a drive mechanism. The drive mechanism is located on the machine body, and the brush head is connected to the drive mechanism. The user lays the paper flat on the worktable of the machine body, allowing the brush head to move back and forth in a straight line, thus enabling the brush head to spray patterns onto the paper. After the brush head moves and sprays, the user needs to control the movement of the paper so that the brush head can continue to move and spray in a straight line on the paper, ultimately forming a large-sized pattern.
[0004] The aforementioned technical solutions have the following drawbacks: when the user moves the paper, the printing press stops. When the printing press restarts printing, the ink in the printing press brush head is prone to drying out, resulting in poor ink flow and affecting printing quality. Utility Model Content
[0005] In order to reduce the chance of ink drying inside the printhead when the printing press stops, this application provides a printhead moisturizing device for printing presses.
[0006] The printing press nozzle moisturizing device provided in this application adopts the following technical solution:
[0007] A printing press nozzle moisturizing device includes a printing press, a moisturizing box, and multiple nozzles. The printing press is equipped with a brush head and a drive mechanism. The drive mechanism is mounted on the printing press, and the brush head is connected to the drive mechanism. The drive mechanism is used to drive the brush head to move back and forth in a straight line. The moisturizing box is located on one side of the printing press, and the multiple nozzles are located inside the moisturizing box. The brush head is moved into the moisturizing box by the drive mechanism, and the nozzles are used to spray water mist.
[0008] By adopting the above technical solution, a moisturizing box is set on one side of the printing press, so that the upper surface of the moisturizing box is flush with the printing press table. When the drive mechanism moves the brush head, the brush head can cover the opening of the moisturizing box, and the nozzle inside the moisturizing box can spray water mist, thereby keeping the ink in the ink outlet of the brush head moist. When the drive mechanism moves the brush head and sprays ink, the printing quality can be guaranteed and the chance of ink drying in the nozzle can be reduced.
[0009] Optionally, a sponge brush is provided inside the moisturizing box, with the top surface of the sponge brush flush with the top surface of the moisturizing box and a gap between the bottom surface of the sponge brush and the bottom of the moisturizing box.
[0010] By adopting the above technical solution, a sponge brush is placed inside the humidification box, allowing the sponge brush to contact the bottom surface of the brush head. This enables the sponge brush to absorb moisture from the surface of the brush head, resulting in higher printing quality. When the brush head is removed from the humidification box by the drive mechanism, the brush head rubs against the sponge brush, keeping the brush head dry.
[0011] Optionally, a lid is rotatably connected to the humidifying box, and the lid is used to cover the humidifying box.
[0012] By adopting the above technical solution, a lid is set on the moisturizing box so that the lid can be placed on the moisturizing box. When the brush head moves and prints, the lid is placed on the moisturizing box, thereby reducing the chance of dust entering the moisturizing box and adhering to the surface of the brush head.
[0013] Optionally, a motor is provided outside the humidifying box, which is used to drive the lid to rotate automatically.
[0014] By adopting the above technical solution, a motor is installed outside the humidification box, which can drive the lid to rotate, thereby reducing the number of manual operation steps required by the user.
[0015] Optionally, the humidification box is equipped with a humidity sensor, which is used to detect the humidity inside the humidification box.
[0016] By adopting the above technical solution, a humidity sensor is installed in the humidification box to detect the humidity inside the box. When the humidity inside the humidification box is too high, the user can manually turn off the nozzle, thereby reducing the chance of water adhering to the brush head on the inner surface of the humidification box.
[0017] Optionally, a fan is provided inside the humidifying box, and the fan passes through the side wall of the humidifying box and is fixedly connected to the humidifying box.
[0018] By adopting the above technical solution, a fan is installed inside the moisturizing box, which can extract air from the box. When the humidity inside the box is too high, the fan can work and extract the humid air, thereby reducing the chance that the brush head will have water adhering to the inner surface of the box.
[0019] Optionally, the humidification box is equipped with a limit switch, which is used to contact the brush head and control the operation or braking of the spray head.
[0020] By adopting the above technical solution, and by setting a limit switch on the humidification box, when the brush head moves into the humidification box, the brush head can contact the limit switch, thereby making the print head work and spraying water mist. When the brush head is removed from the humidification box and printing begins, the brush head loses contact with the limit switch, at which point the print head stops spraying water, saving energy.
[0021] Optionally, the moisturizing box is provided with a water outlet, which is located on the side wall of the moisturizing box. The moisturizing box is provided with a water outlet pipe, one end of which is connected to the water outlet.
[0022] By adopting the above technical solution, and by setting a water outlet on the moisturizing box, the clean water inside the moisturizing box can flow out through the water outlet, thereby keeping the water level inside the moisturizing box low and reducing the chance of water in the moisturizing box submerging the brush head and adhering to the surface of the brush head.
[0023] In summary, the beneficial technical effects of this application are as follows:
[0024] 1. By setting a humidification box on one side of the printing press, the upper surface of the humidification box is flush with the printing press worktable. When the drive mechanism moves the brush head, the brush head can cover the opening of the humidification box, and the nozzle inside the humidification box can spray water mist, thereby keeping the ink in the ink outlet of the brush head moist. When the drive mechanism moves the brush head and sprays ink, the printing quality can be guaranteed and the chance of ink drying in the nozzle can be reduced.
[0025] 2. By setting a lid on the humidification box, the lid can be placed on the humidification box. When the brush head moves and prints, the lid is placed on the humidification box, thereby reducing the chance of dust entering the humidification box and adhering to the surface of the brush head.
[0026] 3. By setting a water outlet on the moisturizing box, the clean water inside the moisturizing box can flow out through the water outlet, thereby keeping the water level inside the moisturizing box low and reducing the chance of water submerging the brush head and adhering to the surface of the brush head.

[0031] The present application will be further described in detail below with reference to the accompanying drawings.
[0032] This application discloses a printhead moisturizing device for a printing press, referring to... Figure 1 and Figure 2 The printing press includes a printing press 1, a humidifier box 2, and multiple printheads 3. The printing press 1 is equipped with a brush head 11 and a drive mechanism 12. The drive mechanism 12 drives the brush head 11 to reciprocate in a straight line. The brush head 11 moves horizontally along the length of the drive mechanism 12, with its orientation vertically downwards. By placing paper on the printing press 1's worktable, the brush head 11 slides back and forth, printing patterns onto the paper. The humidifier box 2 is located on one side of the printing press 1. The brush head 11 can slide into the humidifier box 2 via the drive mechanism 12. Multiple printheads 3 are located inside the humidifier box 2. The printheads 3 spray clean water or water mist to keep the ink in the nozzles of the brush head 11 moist, reducing the chance of ink drying. After the brush head 11 moves and prints, it needs to stop moving so the operator can perform other printing processes such as moving the paper. After these processes are completed, the brush head 11 moves again to print. At this time, the ink in the brush head 11 remains moist, resulting in high print quality.
[0033] Reference Figure 1 The humidification box 2 is flush with the worktable of the printing machine 1. The opening of the humidification box 2 is vertically upward. The brush head 11 can slide to the position covered on the humidification box 2 through the drive mechanism 12. At this time, the bottom surface of the brush head 11 is inside the humidification box 2. The nozzle 3 sprays water to make the humidity inside the humidification box 2 relatively high. When the brush head 11 moves into the humidification box 2, the ink inside the brush head 11 has a low chance of drying.
[0034] Reference Figure 2 and Figure 3 Multiple printheads 3 are mounted on the side walls of the humidification box 2. A lid 4 is rotatably connected to the humidification box 2, and the lid 4 is used to cover the humidification box 2. When the brush head 11 is removed from the humidification box 2 for printing, the lid 4 can cover the humidification box 2, thereby reducing the chance of dust entering the humidification box 2 and reducing the chance of dust adhering to the brush head 11. A motor 41 is mounted on the humidification box 2, the housing of the motor 41 is fixed to the humidification box 2, and the output shaft of the motor 41 is connected to the lid 4, and the motor 41 is used to drive the lid 4 to rotate.
[0035] Reference Figure 2 and Figure 3 A humidity sensor 5 is installed inside the humidification box 2, penetrating the humidification box 2. An electrical wire is attached to one end of the humidity sensor 5 located outside the humidification box 2. The humidity sensor 5 detects the humidity inside the humidification box 2. When the humidity inside the humidification box 2 is high, the user closes the printhead 3 based on the data from the humidity sensor 5, thereby reducing the likelihood of liquid water forming on the surface of the brush head 11 and ensuring better printing quality.
[0036] Reference Figure 3A fan 6 is installed on the humidification box 2, and the fan 6 passes through and is fixed to one side wall of the humidification box 2. The fan 6 is used to extract air from the humidification box 2. When the humidity inside the nozzle 3 is too high, the fan 6 can work to extract the humid air from the humidification box 2, thereby reducing the humidity inside the humidification box 2, so that the ink on the brush head 11 is moistened inside the humidification box 2 and no water droplets accumulate on the surface of the brush head 11.
[0037] Reference Figure 3 A limit switch 7 is installed on the side of the humidifier box 2 away from the printing press 1. The limit switch 7 is used to contact the brush head 11. When the brush head 11 moves into the humidifier box 2 via the drive mechanism 12, the brush head 11 contacts the limit switch 7. The limit switch 7 is connected in series in the power circuit of the printhead 3. When the brush head 11 contacts the limit switch 7, the printhead 3 is energized and sprays water mist. When the brush head 11 moves out of the humidifier box 2 and printing begins, the printhead 3 is de-energized and stops spraying water, saving energy.
[0038] Reference Figure 3 The moisturizing box 2 has a water outlet 8, which is used to drain the water inside the moisturizing box 2. The water outlet 8 is located on the side wall of the moisturizing box 2. A water outlet pipe 9 is connected to the moisturizing box 2, with one end of the water outlet pipe 9 connected to the water outlet 8. When the nozzle 3 sprays out a large amount of water, the water can be discharged from the water outlet 8, keeping the water level inside the moisturizing box 2 low and reducing the chance that the water inside the moisturizing box 2 will submerge the brush head 11 and cause water to adhere to the bottom surface of the brush head 11.
[0039] Reference Figure 3 A sponge brush 21 is provided on the side of the humidifying box 2 near the printing press 1. The sponge brush 21 is snapped into the humidifying box 2, with its bottom surface above the bottom surface of the humidifying box 2 and its top surface flush with the humidifying box 2. When the brush head 11 is inside the humidifying box 2, the nozzle 3 sprays water mist, which easily causes water to adhere to the bottom surface of the brush head 11. When the brush head 11 is removed from the humidifying box 2, its bottom surface comes into contact with the sponge brush 21, which absorbs the liquid water on the surface of the brush head 11, keeping the outer surface of the brush head 11 dry for printing, resulting in higher printing quality.
[0040] The implementation principle of this application embodiment is as follows: by setting a moisturizing box 2 on one side of the printing press 1, the brush head 11 can be moved into the moisturizing box 2 by the drive mechanism 12. The moisturizing box 2 is equipped with a nozzle 3. The nozzle 3 is connected to a water pipe so that the nozzle 3 can spray clean water or water mist, thereby keeping the ink in the brush head 11 moist, reducing the probability of ink drying and clogging the ink outlet, and improving the printing quality.
[0041] 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.
