Description

Technical Field

[0001] The present invention relates to the technical field of UV ink curing, and specifically provides a method for curing UV ink. Background Art

[0002] In order to ensure the aesthetic appearance of metal vacuum cups and glass vacuum cups, they are usually decorated by using self-adhesive labels or screen printing during the production process. However, both of the above two methods have certain defects. For example, self-adhesive labels are prone to falling off and have a relatively high cost; while screen printing will damage the overall appearance effect of the product.

[0003] In view of this, a technical solution for achieving pattern printing by using UV ink has been proposed in the related art. Specifically, a UV printer can be used to directly inkjet the inner surface of a transparent container (i.e., the container to be printed), and then the ejected ink is quickly dried and cured by irradiating with an ultraviolet light source, so as to achieve the purpose of pattern printing.

[0004] However, this process method is very likely to cause the UV light to directly irradiate the ink layer, resulting in some of the ink adhering to the inside of the transparent container after curing. Over time, the problem of ink curing blockage will occur. Summary of the Invention

[0005] The purpose of the present invention is to provide a method for curing UV ink to solve the problem in the above background art that it is very likely to cause the UV light to directly irradiate the ink layer, resulting in some of the ink adhering to the inside of the transparent container after curing, and over time, the problem of ink curing blockage will occur.

[0007] Further, before the method is executed, it further includes: setting at least two pressure value ranges for the expansion airbag and pre-storing corresponding control instructions for each pressure value range; wherein, when the detected pressure is within the first pressure value range, output a first control instruction to make the printing device start working; when the detected pressure is within the second pressure value range, output a second control instruction to stop the printing device from working.

[0008] Further, the expansion airbag has a plurality of air inlets and air outlets.

[0009] Further, the inflatable airbag includes a first section, a second section, and a third section connected in sequence; wherein, the first section is provided with a plurality of air inlets, the second section is provided with a plurality of air outlets, and the third section is provided with a plurality of air inlets.

[0010] Further, the first section, the second section, and the third section are all cylindrical.

[0011] Further, the first section, the second section, and the third section have the same diameter.

[0012] Further, the first section, the second section, and the third section have different thicknesses.

[0013] Further, the first section, the second section, and the third section are of an integrally formed structure.

[0014] Further, the cup body fixing fixture has a cup bottom chuck, side wall claws, and a connecting plate; wherein, the cup bottom chuck and the side wall claws are disposed on both sides of the connecting plate at intervals, and the through hole is formed at one end of the side wall claws away from the cup bottom chuck.

[0015] The present invention provides a method for curing UV ink, which has the following beneficial effects: by inflating the inflatable airbag in the transparent container, the inflatable airbag can be attached to the inner wall of the transparent container, so that the UV lamp can be prevented from directly irradiating the ink layer, thereby solving the problem of ink curing blockage. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 It is a schematic structural diagram of a method for curing UV ink according to the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following further describes in detail the embodiments of the present invention in conjunction with the drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0018] See Figure 1 As shown, the embodiment of the present invention provides a method for curing UV ink, including the following steps:

[0019] Place the transparent container in the cup body fixing fixture;

[0020] Specifically, the transparent container to be processed can be first placed in the cup body fixing fixture for subsequent positioning and fixing.

[0021] Insert the air guide rod into the transparent container and pass it through the through hole in the cup body fixing fixture;

[0022] Specifically, the air guide rod can be driven by a driving mechanism to slide in the up and down direction, so that the air guide rod extends into the transparent container and passes through the through hole in the cup body fixing fixture.

[0023] Inflate a certain amount of gas into the expansion airbag on the guiding air rod so that the expansion airbag fits against the inner wall of the transparent container;

[0024] Specifically, it can be connected to the expansion airbag through an air duct, and a certain amount of gas is inflated into the expansion airbag by means of a compressed air pump, so that the expansion airbag gradually expands until it completely fits against the inner wall of the transparent container.

[0025] In summary, for the UV ink curing method provided by the present invention, by inflating the expansion airbag in the transparent container, the expansion airbag can be made to fit against the inner wall of the transparent container, thus avoiding the direct irradiation of UV light onto the ink layer, and further solving the problem of ink curing blockage.

[0026] In practical applications, in order to avoid the problem that it cannot be taken out smoothly due to the too large volume of the expansion airbag, preferably, before the method is executed, at least two pressure value ranges can be set for the expansion airbag, and corresponding control instructions are pre-stored for each pressure value range.

[0027] Specifically, when the detected pressure is within the first pressure value range, output the first control instruction to make the printing device start working;

[0028] When the detected pressure is within the second pressure value range, output the second control instruction to stop the working of the printing device.

[0029] That is to say, the printing device can only be started after the expansion airbag is filled with gas, otherwise the expansion airbag needs to be inflated again.

[0030] Of course, in practical applications, users can also adjust the pressure value range according to the actual situation to better meet different requirements.

[0031] As an alternative implementation manner, the expansion airbag has a plurality of air inlets and air outlets.

[0032] Specifically, gas can be inflated into the expansion airbag through a plurality of air inlets, and at the same time, the excess gas is discharged through a plurality of air outlets.

[0033] As another alternative implementation manner, the expansion airbag includes a first section, a second section and a third section connected in sequence;

[0034] Wherein, the first section is provided with a plurality of air inlets, the second section is provided with a plurality of air outlets, and the third section is provided with a plurality of air inlets.

[0035] Specifically, gas can be inflated into the first section and the third section through a plurality of air inlets, and at the same time, the excess gas in the second section is discharged through a plurality of air outlets.

[0036] As another alternative embodiment, the first section, the second section, and the third section are all cylindrical.

[0037] Specifically, the overall shape of the inflatable airbag is a three - section cylindrical shape, which not only facilitates the manufacture of the inflatable airbag but also improves its sealing performance.

[0038] As another alternative embodiment, the diameters of the first section, the second section, and the third section are the same.

[0039] Specifically, the diameters of the three cylindrical sections are kept consistent, which not only helps to improve the strength of the inflatable airbag but also enables it to be more easily pressed against the inner wall of the transparent container.

[0040] As another alternative embodiment, the thicknesses of the first section, the second section, and the third section are different.

[0041] Specifically, in order to ensure the stability of the inflatable airbag after inflation, the thicknesses of the first section and the third section can be designed to be larger than that of the second section.

[0042] As another alternative embodiment, the first section, the second section, and the third section are of an integrally formed structure.

[0043] Specifically, the inflatable airbag is manufactured by means such as injection molding, which not only reduces the production difficulty but also reduces the assembly error.

[0044] As another alternative embodiment, the cup - body fixing fixture has a cup - bottom chuck, side - wall claws, and a connecting plate;

[0045] Among them, the cup - bottom chuck and the side - wall claws are arranged on both sides of the connecting plate at intervals, and a through - hole is formed at one end of the side - wall claws away from the cup - bottom chuck.

[0046] Specifically, the cup - bottom chuck is used to fix the bottom of the transparent container, the side - wall claws are used to fix the side of the transparent container, and the air - guiding rod can pass through the gap between the side - wall claws and reach the inside of the transparent container.

[0047] In summary, the UV ink curing device provided by the present invention can make the inflatable airbag fit against the inner wall of the transparent container by inflating the inflatable airbag in the transparent container, thus avoiding the direct irradiation of the UV lamp on the ink layer and then solving the problem of ink curing blockage.

[0048] The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to best explain the principles of the invention and its practical application, and to enable those of ordinary skill in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.
