Description

Technical Field

[0001] This application belongs to the field of feeding equipment technology, specifically a feeding device for a UV machine. Background Technology

[0002] UV printers use piezoelectric inkjet printing technology. The voltage inside the printhead causes the ink in the nozzle orifice to be ejected onto the surface of the substrate, thereby achieving the purpose of printing images. Generally, a small nozzle has thousands of nozzle orifices, which are difficult to see with the naked eye. The amount of ink output from the nozzle orifice can be precisely controlled. The ultraviolet light emitted by the LED cold light source reacts with the photosensitive curing agent in the UV ink, causing the pigment molecules in the UV ink to solidify on the material surface, thereby achieving ink drying.

[0003] Referring to CN219927315 U, a water-cooled modified UV printer ink transfer device belongs to the field of digital printing technology. This water-cooled modified UV printer ink transfer device includes a UV printer. The UV printer printhead has a left-side through-hole and a right-side through-hole, both of which are sealed and fixedly connected to a condenser pipe. The side of the condenser pipe furthest from the UV printer is fixedly connected to a condenser, which provides condensate water for cooling. The condenser pipe circulates condensate water to cool the UV printer printhead. A pressure pump is installed at the connection point between the condenser pipe and the condenser. One end of the pressure pump is sealed to the condenser pipe, and the other end is fixedly connected to one side of the condenser. This device can solve the problem of poor heat dissipation of existing UV printer printheads, causing irreversible damage to the printer and resulting in decreased print quality.

[0004] However, the following problems still exist. When the ink cartridges of the existing UV printers are fed, the ink stored in the ink tank is pumped into the printing area by the ink pump. After the ink tank is left for a long time, the ink sits for too long and contains large particles of impurities, which leads to uneven feeding and easy ink blockage, affecting the printing quality and working efficiency of the UV printer. Utility Model Content

[0005] The purpose of this application is to address the problem mentioned above: in the existing UV printer ink cartridge feeding process, ink stored in the ink tank is pumped into the printing area by an ink pump. After the ink tank is left to stand for a long time, the ink contains large particles of impurities, which leads to uneven feeding, easy ink blockage, and affects the printing quality and working efficiency of the UV printer. The application provides a feeding device for a UV printer.

[0006] The technical solution adopted in this application is as follows: A feeding device for a UV machine includes a UV machine body, an ink cartridge fixedly connected to the upper surface of the UV machine body, a metering pump fixedly connected to the inner wall of the ink cartridge, an ink inlet pipe fixedly connected to the water inlet end of the metering pump, an ink outlet pipe fixedly connected to the water outlet end of the metering pump, a threaded hollow cylinder rotatably connected to the end of the ink outlet pipe away from the metering pump, a support frame fixedly connected to the bottom wall of the inner wall of the ink cartridge, a heat insulation shell fixedly connected to the upper surface of the support frame, an ink cylinder fixedly connected to the upper surface of the heat insulation shell, an mounting cylinder fixedly connected to the side of the ink cylinder, the inner wall of the mounting cylinder being threadedly connected to the surface of the threaded hollow cylinder, a filter screen fixedly connected to the side of the threaded hollow cylinder near the ink cylinder, a connecting pipe fixedly connected to the front of the ink cylinder, and a printing mechanism fixedly connected to the end of the connecting pipe away from the ink cylinder.

[0007] By adopting the above technical solution, firstly, when the level sensor detects that the ink level in the ink cartridge is low, the controller turns on the metering pump. The metering pump operates according to the set parameters to draw a fixed amount of ink from the ink storage tank and draws it into the ink cartridge through the ink inlet and outlet pipes. During the process of drawing the ink into the ink cartridge, the ink passes through the filter screen to filter out impurities and clumps. When the temperature sensor detects that the ink level in the ink cartridge is low, the controller turns on the heating wire. The heating wire heats up the ink in the ink cartridge and at the same time turns on the stirring motor. The stirring motor drives the stirring rod to rotate and stir the ink in the ink cartridge, making the ink concentration uniform. Then, the ink enters the printing mechanism through the connecting pipe for printing, which solves the problem of pipe blockage to a certain extent.

[0008] In a preferred embodiment, a stirring motor is fixedly connected to the side of the support frame, and a stirring rod is fixedly connected to the output end of the stirring motor.

[0009] By adopting the above technical solution and setting up a stirring motor, the stirring rod can be rotated after operation to stir the ink in the ink cylinder evenly, reducing the occurrence of clumping.

[0010] In a preferred embodiment, a liquid level sensor and a temperature sensor are respectively provided on the inner wall of the ink cartridge, and a controller is provided on the front of the ink cartridge.

[0011] By adopting the above technical solution and setting a liquid level sensor, the ink level in the ink cartridge can be detected, and then the signal is transmitted to the controller. The controller then uses a metering pump to draw ink into the ink cartridge.

[0012] In a preferred embodiment, an electric heating wire is fixedly connected to the inner wall of the heat insulation shell. By setting the electric heating wire, a temperature sensor detects the temperature of the ink cartridge. When the ink in the ink cartridge is low...

[0013] By adopting the above technical solution, the heating wire is turned on by the controller to increase the temperature of the ink in the ink cartridge, thereby reducing the occurrence of ink clumping.

[0014] In a preferred embodiment, a support plate is fixedly connected to the inner wall of the ink cartridge, an ink storage box is fixedly connected to the upper surface of the support plate, and the end of the ink inlet pipe away from the metering pump passes through the lower surface of the support plate and is fixedly connected to the lower surface of the ink storage box.

[0015] By adopting the above technical solution and setting up an ink storage box, ink can be stored.

[0016] In a preferred embodiment, a stopper block is fixedly connected to the upper surface of the ink storage box, and a fixing cylinder is threadedly connected to the inner wall of the stopper block.

[0017] By adopting the above technical solution and setting a fixed cylinder, when the ink in the ink storage tank is used up, the fixed cylinder can be pulled out from the stopper block, and new ink can be refilled into the ink storage tank for storage.

[0018] In a preferred embodiment, the ink cartridge has heat dissipation holes on its side, and a support leg is fixedly connected to the lower surface of the UV printer body.

[0019] By adopting the above technical solution and setting heat dissipation holes, air circulation inside the ink cartridge can be maintained, and heat dissipation of the metering pump can be enhanced.

[0020] In a preferred embodiment, a sealing gasket is adhered to the surface of the threaded hollow cylinder, and the sealing gasket is made of rubber.

[0021] By adopting the above technical solution and setting a sealing gasket, when the threaded hollow cylinder is rotated and fixed in the mounting cylinder, the sealing gasket blocks the space between the threaded hollow cylinder and the mounting cylinder, thereby increasing the sealing performance.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0023] 1. In this application, when the level sensor detects that the ink level in the ink cartridge has dropped, the metering pump is activated by the controller. The metering pump operates according to the set parameters to draw a fixed amount of ink from the ink storage tank and draws it into the ink cartridge through the ink inlet and outlet pipes. During the process of drawing the ink into the ink cartridge, the ink passes through the filter screen to filter out ink containing impurities and clumps. When the temperature sensor detects that the ink level in the ink cartridge has dropped, the heating wire is activated by the controller. The heating wire heats up the ink in the ink cartridge and at the same time, the stirring motor is activated. The stirring motor drives the stirring rod to rotate and stir the ink in the ink cartridge, making the ink concentration uniform. Then, the ink enters the printing mechanism through the connecting pipe for printing, which solves the problem of pipe blockage to a certain extent. Attached Figure Description

By setting a filter screen 18, the filter screen 18 can be rotated away from the installation cylinder 19 and pulled out from the installation cylinder 19, thereby facilitating the removal of the filter screen 18 and subsequent cleaning of the filter screen 18.

A connecting pipe 15 is fixedly connected to the front of the ink cylinder 12. The end of the connecting pipe 15 away from the ink cylinder 12 is fixedly connected to the printing mechanism 3. First, when the liquid level sensor 25 detects that the ink level in the ink cylinder 12 has become low, the metering pump 11 is turned on by the controller 4. The metering pump 11 operates according to the set parameters to draw a certain amount of ink from the ink storage tank 8 and draws it into the ink cylinder 12 through the ink inlet pipe 13 and the ink outlet pipe 14. During the process of drawing ink into the ink cylinder 12, the ink passes through the filter screen 18 to filter out ink with impurities and clumps. When the temperature sensor 24 detects that the ink level in the ink cylinder 12 has become low, the heating wire 21 is turned on by the controller 4. The heating wire 21 heats up the ink in the ink cylinder 12 and at the same time, the stirring motor 23 is turned on. The stirring motor 23 drives the stirring rod 22 to rotate and stir the ink in the ink cylinder 12 to make the ink concentration uniform.

The controller 4 draws ink into the ink cartridge 12 through the metering pump 11.

When the ink in the ink cylinder 12 is low, the controller 4 turns on the heating wire 21 to raise the ink temperature in the ink cylinder 12 and reduce the occurrence of ink clumping. When the ink temperature in the ink cylinder 12 is high, the controller 4 turns off the heating wire 21 to keep the temperature in the ink cylinder 12 constant.

By setting the sealing gasket 16, when the threaded hollow cylinder 17 is rotated and fixed in the mounting cylinder 19, the sealing gasket 16 blocks the space between the threaded hollow cylinder 17 and the mounting cylinder 19, thereby increasing the sealing performance.

[0040] The implementation principle of the feeding device embodiment for a UV machine in this application is as follows: First, when the liquid level sensor 25 detects that the ink level in the ink cylinder 12 has become low, the metering pump 11 is turned on by the controller 4. The metering pump 11 operates according to the set parameters to draw a certain amount of ink from the ink storage tank 8 and draws it into the ink cylinder 12 through the ink inlet pipe 13 and the ink outlet pipe 14.
