Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, in particular to a web cold stamping printing equipment. Background Art

[0002] With the development of society and the improvement of people's lives, more and more daily necessities require exquisite printing and fine hot stamping. Hot stamping methods mainly include hot stamping and cold stamping. Cold stamping usually uses ultraviolet curing varnish to transfer the hot stamping foil to the surface of the printing material. Cold stamping has the advantages of no need to make metal hot stamping plates, no need for heating devices, and a wide range of hot stamping substrates. However, cold stamping also has its shortcomings. The UV glue used for cold stamping has poor leveling and is not smooth, which causes diffuse reflection on the surface of the cold stamping foil, affecting the color and gloss of the stamped images and texts.

[0003] With the continuous installation and use of web-fed cold stamping equipment, the following problems were found during use:

[0004] 1. Traditional web-fed cold stamping equipment does not have a device for evenly applying UV glue, which affects the color and gloss of the stamped images.

[0005] 2. Traditional web-fed cold foil printing equipment does not have a calibration device for the hot foil and the web during cold foiling. During hot foiling, the operation of the device will inevitably cause deviation, thus affecting the product effect.

[0006] 3. Traditional web cold stamping equipment does not have a device to press the hot stamping foil and web paper, and only relies on UV spotlights for fixed drying.

[0007] Therefore, it is necessary to design a web cold stamping printing device to address the above problems. Utility Model Content

[0038] Embodiment 2: The adjustment structure 6 is composed of a horizontal plate 601, a slot 602, a clamping strip 603, a limiting tube 604, a limiting slot 605 and a fixing spring 606. The horizontal plate 601 is arranged on one side of the connecting plate 31 close to the fifth support rod 23. A limiting slot 605 is provided at the middle position inside the horizontal plate 601, and limiting tubes 604 are provided on both sides inside the limiting slot 605. A fixing spring 606 is provided at the central position inside the limiting tube 604, and clamping strips 603 are installed at both ends of the fixing spring 606. The top end of the clamping strip 603 passes through the limiting tube 604 and extends to the outside of the limiting tube 604. Six clamping slots 602 are provided at both ends of the horizontal plate 601.

[0039] A fixing plate 30 is disposed on one side of the limiting tube 604 close to the fourth support rod 22, and two second limiting rollers 33 are installed at one end of the fixing plate 30;

[0040] The clamping slot 602 and the clamping strip 603 match each other, and the limiting tube 604 and the limiting slot 605 are slidably connected;

[0041] Specifically, Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, by squeezing the clamping strip 603 toward the middle, the fixed spring 606 is driven to contract, so that the cross plate 601 is separated from the clamping slot 602, and then the limiting tube 604 is moved to reach the appropriate position, and then the clamping strip 603 is released. Under the action of the fixed spring 606, the clamping strip 603 is re-engaged with the clamping slot 602, so that not only can cold stamping be performed at any point on the surface of the roll paper, but also the position of the hot stamping foil and the roll paper is limited, which is convenient for better performing the next step of operation.

[0042] Embodiment 3: The clamping structure 7 is composed of a slide 701, a return spring 702, a slide bar 703 and a squeeze roller 704.

Both ends of the return spring 702 are connected to the slide bar 703. One end of the slide bar 703 is installed with a squeeze roller 704 through a bearing.

[0043] The slide bar 703 and the slide groove 701 are slidably connected, and two groups of the slide groove 701, the return spring 702 and the slide bar 703 are symmetrically arranged at both ends of the squeezing roller 704;

[0044] Specifically, Figure 1 and Figure 3 As shown, when in use, the squeezing roller 704 is first moved to one side, and one end of the hot stamping foil and the roll paper is passed through between the squeezing rollers 704. Then, under the action of the return spring 702, the squeezing rollers 704 are squeezed against each other through the slide bar 703, so that the hot stamping foil and the roll paper are more closely attached to each other, preventing the color and gloss of the hot stamping from being affected during the printing process.

[0045] Working principle: When using this device, first power on the device and start it. At this time, the damping motor 1 drives the winding roller 2 to rotate and slowly retracts the web of paper. At this time, the web of paper is pulled out from the unwinding roller 16, crosses the surfaces of the first conveying roller 15 and the second conveying roller 17, and is transferred to the top of the fixed block 14. At this time, the UV glue inside the glue box 11 slides through the opening at the bottom of the glue box 11 to the surface of the first glue pressing roller 10.

[0046] At the same time, the driving motor 29 drives the first glue pressing roller 10 to rotate, and the belt 9 makes the two first glue pressing rollers 10 rotate at the same time, so that the UV glue is evenly applied to the surface of the web, and then passes through the third roller 8, and is transferred to the inside of the hot stamping box 25 through the gap between the first limiting roller 32 and the second limiting roller 33, and then squeezes the card strip 603 toward the middle, driving the fixed spring 606 to contract, so that the cross plate 601 is separated from the card slot 602, and then the limiting tube 604 is moved. After reaching the appropriate position, the card strip 603 is released. Under the action of the fixed spring 606, the card strip 603 is re-engaged with the card slot 602. At this time, the hot stamping foil is transferred from the discharge roller 4 through the second roller 5 to the second limiting roller 33 for clamping.

[0047] Finally, the hot stamping foil and the web of paper pass through the squeezing roller 704 at the same time, and under the action of the return spring 702, the slide bar 703 is pulled to drive the squeezing roller 704 to be squeezed toward the middle, and finally, after being sprayed by the printer 28 and irradiated by the curing lamp 26, the cold stamping printing is completed, and then it is transferred to the surface of the winding roller 2 through the fourth roller 27 and the first roller 3.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
