Description

Technical Field

[0001] The invention relates to the technical field of printing, in particular to a laser transfer machine. Background Art

[0002] At present, laser patterns are commonly used as anti-counterfeiting marks. The general laser mark is formed by covering a layer of laser pattern film on the base paper. The formation of this laser mark requires three steps: producing the base paper, producing the laser film, and compounding the two together. The production process is complicated. Special UV varnish is fully or partially coated on the surface of the printed matter. After passing through the UV curing device, the ink surface is cured, and then the film is peeled off. At this time, the holographic pattern on the pre-treated film is completely transferred to the surface of the printed matter.

[0003] The patent document with application number CN202010998694.8 discloses a laser printing process. The key points of its technical solution are that it includes a first pressing roller, a second pressing roller and a driving device. The first pressing roller is used to guide the transfer film, and the second pressing roller is on the inner side of the conveyor belt. When in use, the driving device drives the first pressing roller and the second pressing roller to move toward each other. The first pressing roller presses the transfer film onto the conveyor belt, and the second pressing roller supports the conveyor belt.

[0004] However, the above equipment has some shortcomings. Since it is necessary to print base papers of different thicknesses, if no corresponding adjustments are made and printing is done directly, the printing quality of the final printed product will be affected. In order to achieve the best printing effect, before printing different batches, it is necessary to adjust the printing parameters in the film pressing device in advance, such as the position of the film, the height of the hot pressing roller, and the position of the UV lamp. All printing equipment needs to be adjusted to the appropriate position, and a new type of laser transfer machine that can be optimized and adjusted needs to be designed. Summary of the invention

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0035] Example 1

[0036] There are various types of paper that need to be laser printed on the current market, some are as thin as cards, and some are multi-layered cardboards. Therefore, different printing heights need to be adjusted to meet the corresponding printed products. In order to improve the final quality of laser printing, the present invention designs a laser transfer machine that can be accurately adjusted and is suitable for various types of printing materials.

[0037] like Figure 1 , Figure 2As shown, specifically, a laser transfer machine of the present invention mainly includes a support frame 1, which is a split type and is assembled from multiple panels. Specifically, it includes a base 11, a transfer support plate 12 and a laser film support plate 13. The transfer support plate 12 and the laser film support plate 13 are two symmetrically arranged on both sides of the base 11 for installing various equipment.

[0038] Among them, a pre-press conveying device 2, a main adsorption steel rod 3 and a post-press conveying device 4 are sequentially arranged on the transfer support plate 12. The printed matter is sequentially loaded from the pre-press conveying device 2, laser printing is completed on the main adsorption steel rod 3, and then transferred out from the post-press conveying device 4. At the same time, a laser mercury lamp 8 is arranged on both the pre-press conveying device 2 and the post-press conveying device 4. The laser mercury lamp 8 arranged on the pre-press conveying device 2 can strengthen and cure the previous UV ink layer of the printed matter before loading and dyeing, so as to prevent the dye of the previous step from being not completely cured, and the residual uncured dye affects the printing step on the main adsorption steel rod 3 in this device, causing pattern errors and reducing the overall printing quality. The laser mercury lamp 8 is arranged on the post-press conveying device 4 to further strengthen and cure the UV ink layer formed on the main adsorption steel rod 3 after printing, so as to prevent the uncured UV ink from affecting the subsequent steps.

[0039] A front hot pressing roller device 5 and a rear hot pressing roller device 6 are respectively arranged on both sides of the main adsorption steel roller 3. The front hot pressing roller device 5 and the rear hot pressing roller device 6 are mainly used to heat the dye on the film and print the dye on the surface of the printed matter by pressure.

[0040] A transfer film device 7 is arranged on the laser film support plate 13, and the transfer film device 7 is located above the main adsorption steel rod 3. A driving motor is also arranged on the side of the main adsorption steel rod 3, which is used to rotate and drive the main adsorption steel rod 3 to roll, so that the printed matter rotates after the main adsorption steel rod 3 is printed, and is rotated and moved to the post-printing conveying device 4 through the post-hot pressing roller device 6.

[0041] like Figure 3 and Figure 7As shown, the transfer film device 7 includes two laser film rollers 71 and multiple laser transfer turning rollers 72, and a film driving motor 711 is arranged at the end of each laser film roller 71. A laser film 73 is wound and connected between the two laser film rollers 71. The two laser film rollers 71 are used to wind the laser film, one is responsible for unwinding and the other is responsible for winding, and the linear speed of rotation is consistent with the linear speed of rotation of the main adsorption steel roller 3. The laser film 73 is wound around the laser transfer turning roller 72, the front hot pressing roller device 5 and the rear hot pressing roller device 6 in turn. A UV lamp 9 is arranged above the main adsorption steel roller 3. The UV lamp 9 irradiates ultraviolet light of a special band to quickly solidify the UV particles in the dye on the printed matter, forming a fixed UV layer covering the entire dye area, isolating the ink from the outside, and the dye will not be transferred to other printed matters during the movement, and has sufficient time to dry.

[0042] like Figure 4-Figure 6 As shown, the pre-press conveying device 2 and the post-press conveying device 4 are symmetrically arranged. The structures of the pre-press conveying device 2 and the post-press conveying device 4 are basically the same, and they mainly convey printed materials into and out of the transfer area. Specifically, Figure 4 As shown, the pre-press conveying device 2 and the post-press conveying device 4 both include a fixed conveying plate 21 and a suspended conveying plate 22, a conveying drive motor 20 is arranged on the transfer support plate 12, and conveying rollers 23 and a plurality of conveying belts 24 are arranged on the fixed conveying plate 21 and the suspended conveying plate 22, the conveying rollers 23 include an active roller and a driven roller, and a plurality of conveying belts 24 are arranged in parallel, the conveying drive motor 20 and the conveying rollers 23 are connected by a synchronous belt drive, and one end of the suspended conveying plate 22 is rotatably arranged on one side of the fixed conveying plate 21.

[0043] One end of the hanging transport plate 22 away from the fixed transport plate 21 is connected to a hanging control cylinder 221, and the bottom of the hanging control cylinder 221 is fixed on the transfer support plate 12. The telescopic rod of the hanging control cylinder 221 controls the rotation angle of the hanging transport plate 22, so that the hanging transport plate 22 runs at a horizontal angle of 180 degrees, and remains horizontal and parallel to the fixed transport plate 21, and normally receives printed materials. At the same time, the hanging transport plate 22 can also be adjusted to tilt 45 degrees upward or downward, and can be adapted to printing and transportation equipment of other sizes.

[0044] By adjusting the angle of the hanging transport board 22, the position of the printed paper can be adjusted during the loading and unloading process by relying on the change in the transmission angle and the change in the paper's own gravity, thereby reducing the risk of paper jams and paper breaks; at the same time, when the machine is shut down, the entire hanging transport board 22 can be adjusted to a vertical angle of 90 degrees to reduce the occupied space and protect the internal equipment at the same time.

[0045] In order to protect the printed products after printing, it is necessary to cool down in time to prevent the temperature from being too high, which makes it difficult for the printing dye to cool and solidify. An internal cooling water tank plate 25 is provided on the fixed transport plate 21 and the hanging transport plate 22, and a fixed cooling water tank plate 26 is provided between the fixed transport plate 21 and the hanging transport plate 22. The laser mercury lamp 8 is located above the fixed cooling water tank plate 26. A support column 211 is provided at the bottom of the fixed transport plate 21, and a water tank support plate 212 is provided on the support column 211. The fixed cooling water tank plate 26 is fixed on the water tank support plate 212.

[0046] like Figure 7-9 As shown, the front hot pressing roller device 5 of the present invention includes a front hot pressing roller 51 and two front rubber roller control devices 52 symmetrically arranged at both ends of the front hot pressing roller 51 , and movable connecting bearings 511 are arranged at both ends of the front hot pressing roller 51 .

[0047] Specifically, Figure 7 and 9 As shown, the front rubber roller control device 52 includes a front L-shaped movable rod 521, a front transfer bearing 522 and a front drive device 53. The front drive device 53 controls the distance between the front heating pressure roller 51 and the main adsorption steel roller 3 by controlling the rotation angle of the L-shaped movable rod 521.

[0048] The front L-shaped movable rod 521 is composed of two straight rods at 90 degrees. The middle part of the front L-shaped movable rod 521 is rotatably connected to the front transfer bearing 522, and the front transfer bearing 522 is fixed on the transfer support plate 12. The upper end of the front L-shaped movable rod 521 is fixed on the movable connection bearing 511, and the lower end of the front L-shaped movable rod 521 is connected to the front drive device 53.

[0049] In order to enable the front heated pressing roller 51 to maintain appropriate pressure and avoid excessive printing pressure causing the printing ink to be compressed and the printed pattern to be chaotic, or too little pressure causing insufficient transfer of the printed ink and ink residue, the position of the front heated pressing roller 51 needs to be controlled.

[0050] Since the laser film 73 is rotated and wound on the front heating pressure roller 51, the contact point between the laser film 73 and the printed matter moves synchronously with the front heating pressure roller 51. Therefore, only the lower end of the front L-shaped movable rod 521 needs to be rotated to move the position of the front heating pressure roller 51, thereby adjusting the distance between the front heating pressure roller 51 and the main adsorption steel roller 3, thereby adjusting the printing pressure between the laser film 73 and the printed matter.

[0051] Specifically, the front drive device 53 includes a front private service screw rod 531 and a private service electric cylinder 532. The front end of the front private service screw rod 531 is rotatably connected to the lower end of the L-shaped movable rod 521. Since the front heating roller 51 is the most important component responsible for the entire printing, the position of the front heating roller 51 needs to be accurately controlled. The private service electric cylinder 532 and the front private service screw rod 531 have a stable power output through the private service electric cylinder 532, and the force of pushing the front private service screw rod 531 is uniform and soft, which will not cause the front heating roller 51 to have a large impact force on the laser film 73.

[0052] Similarly, the position of the rear hot pressing roller device 6 needs to be adjusted and controlled. The rear hot pressing roller device 6 includes a rear hot pressing roller 61, a rear rubber roller control device 62 and a rear drive device 63. The rear rubber roller control device 62 includes a rear L-shaped movable rod 621 and a rear transfer bearing 622. The rear drive device 63 is a reciprocating cylinder. The main function of the rear hot pressing roller device 6 is to heat again and transfer the printing ink that may remain on the laser film 73 to the surface of the printed matter to perform an insurance supplement.

[0053] Both the front heating roller 51 and the rear heating roller 61 are provided with electric heating devices, and the electric heating devices are connected to a 380V power supply, and are provided with temperature control devices to control the temperature during printing.

[0054] The present invention arranges a front heating pressing roller 51 and a rear heating pressing roller 61 on both sides of a main adsorption steel roller 3 to perform double heating printing, so that the printing ink on the laser film is fully bonded, and at the same time a protective isolation space is formed between the front heating pressing roller and the rear heating pressing roller. The film is synchronously rotated and fitted with the printed matter on the upper part of the main adsorption steel roller, thereby increasing the contact time, increasing the bonding and curing time of the printing ink, allowing the printing ink on the film to be fully bonded to the printed matter, and allowing the UV ink to form a protective film layer.

[0055] At the same time, in order to make the UV lamp 9 at the optimal irradiation height, it is necessary to make corresponding adjustments after the front heating pressure roller 51 moves. Therefore, lamp adjustment cylinders 91 are provided at both ends of the UV lamp 9, and the telescopic rod of the lamp adjustment cylinder 91 moves up and down to control the irradiation height of the UV lamp 9.

[0056] like Figure 7-8 As described above, in order to be able to adjust the tension of the laser film 73, the transfer film device 7 also includes a tension adjustment rod 74, and adjustment rods 75 are provided at both ends of the tension adjustment rod 74. A sliding block 76 that can move up and down is provided on the adjustment rod 75. The two ends of the tension adjustment rod 74 are fixed on the sliding block 76. Six laser transfer turning rollers 72 are provided in the middle and are symmetrically arranged into two groups. The tension adjustment rod 74 is located between the two groups of laser transfer turning rollers 72.

[0057] The adjustable tension rod can adjust the tension of the laser film so that the ink on the laser film can be bonded to the printed matter with appropriate tension, thus improving the final printing effect.

[0058] A vacuum pump 10 is disposed on the base 11, and the vacuum pump 10 provides gas control power for various cylinders in the device of the present invention.

[0059] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0060] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
