Description

Technical Field

[0001] The invention relates to the technical field of hot stamping machines, and in particular to a hot stamping machine capable of automatically correcting paper. Background Art

[0002] The hot stamping machine is a device that completes the hot stamping process. The hot stamping process is a special printing process that does not use ink. It uses a certain temperature and pressure to hot stamp the electrochemical aluminum foil onto the surface of the substrate. The working principle of the hot stamping machine is to use the principle of heat pressure transfer. Under the action of combined pressure, the electrochemical aluminum contacts the hot stamping plate and the substrate. The heat of the electrochemical aluminum melts the hot-melt dyeing resin layer and the adhesive. The aluminum layer is peeled off from the electrochemical aluminum base film and transferred to the substrate. As the pressure is removed, the adhesive quickly cools and solidifies, and the aluminum layer firmly adheres to the substrate to complete the hot stamping process.

[0003] In the process of hot stamping paper, the hot stamping machine in the prior art can place the stacked multiple papers neatly near the hot stamping head with the help of manual or other transfer equipment, and then take and load the papers in turn with the help of relevant loading and unloading equipment. However, since there is no relevant automatic correction mechanism for the papers inside the hot stamping machine, the papers stacked in a higher position are easily vibrated during the operation of the hot stamping machine, causing the position of the stacked papers to shift, and then causing the loading and unloading equipment to transfer the papers with deviation in position to the bottom of the hot stamping head, causing the hot stamping head to stamp the pattern on the paper surface with deviation, which reduces the aesthetics of the paper hot stamping process and makes the hot stamping machine in the prior art unable to meet people's usage needs.

[0041] As a technical optimization solution of the present invention, the detection mechanism includes two mounting plates installed on the outer wall of one side away from the two horizontal plates 10, and the tops of the two mounting plates are connected to the top plate 11 through the second electric telescopic rod 26, and multiple industrial cameras 32 are installed on the bottom of the top plate 11.

[0042] As a technical optimization solution of the present invention, the cleaning mechanism includes a third chute 21 opened at the top of the two horizontal plates 10, and the third sliders 33 are installed inside the two third chute 21, and the moving rods 28 are installed on the top of the two third sliders 33.

[0043] As a technical optimization solution of the present invention, a fourth slot 34 is provided on the outer wall of the side where the two moving rods 28 are close to each other, and a fourth slider 36 is installed inside the two fourth slots 34. A rectangular strip 29 is installed between the two fourth sliders 36 for common rotation, and a dust collector 39 is installed on the outer wall of one side of the rectangular strip 29. A fourth linear motor is preset inside the two fourth slots 34, and the two fourth linear motors can drive the two fourth sliders 36 to move up and down and adjust inside the corresponding fourth slots 34, and drive the rectangular strip 29 and other components to move and adjust between the two moving rods 28; a second driving device is preset inside one of the fourth sliders 36, and the output end of the second driving device is connected to the rotating part of one end of the rectangular strip 29, so as to drive the rectangular strip 29 to rotate and adjust between the two fourth sliders 36; the dust collector 39 can be connected to the external preset dust collector through the second pipe, so that the dust collector 39 has the effect of automatically removing impurities when in use.

[0044] As a technical optimization solution of the present invention, a groove is provided on the outer wall of the rectangular strip 29 away from the dust collector 39, and a double-headed screw 37 is rotatably installed inside the groove. Two moving blocks 38 are threadedly installed on the outer wall of the double-headed screw 37, and vacuum suction cups 35 are installed on the outer wall of the same side of the two moving blocks 38. A third driving device is preset inside the rectangular strip 29, and the output end of the third driving device is connected to one end of the double-headed screw 37, so that the double-headed screw 37 can be driven to rotate inside the groove, and the two moving blocks 38 and the vacuum suction cups 35 can be moved and adjusted in the direction of approaching or moving away from each other; the two vacuum suction cups 35 are connected to the external preset vacuum device through a hose, so that the two vacuum suction cups 35 can adsorb paper with a smooth surface when in use.

[0045] In the present invention, when the user uses the device, Figure 1As shown, at this time, the rotating plate 12 rotates to an upward vertical state, and multiple papers to be stamped can be stacked and placed inside the first box 7, and the external preset hot air blower is controlled to start, and the preset heating device inside the first box 7 is controlled to start synchronously. The heating device can heat the multiple papers placed inside the first box 7, and control the two first sliders 27 to move downward inside the corresponding first slide grooves 20, driving the rotating plate 12 in a vertical state at this time to move downward to between the first box 7 and the second box 8. At this time, the hot air discharged from the multiple blower heads 30 can be directed to the multiple papers, further improving the heating and drying effect of the multiple papers, and avoiding the low dryness of the papers to be stamped, which affects the subsequent stamping work.

[0046] Furthermore, in order to heat and dry multiple sheets of paper uniformly, when the rotating plate 12 is located between the first box body 7 and the second box body 8, the two driving motors 14 can be controlled to drive the two screw rods 15 to rotate, thereby driving the push plate 17 to push the stacked sheets of paper inside the first box body 7 toward the rotating plate 12, so that one end of the multiple sheets of paper are all in contact with the rotating plate 12. While the multiple blower heads 30 discharge hot air, the two first sliders 27 can be controlled to repeatedly move up and down inside the corresponding first slide grooves 20, driving the rubber pads 31 on one side of the rotating plate 12 to rub against one end of the multiple sheets of paper, driving gaps between the multiple sheets of paper, so that the hot air discharged from the multiple blower heads 30 can enter the gaps between the multiple sheets of paper, so as to facilitate the heat transfer to the central position inside the multiple sheets of paper, thereby improving the efficiency of heating and drying the sheets of paper and bringing convenience to the subsequent hot stamping processing of the sheets of paper.

[0047] Before the paper is hot stamped, heating the paper can make the paper surface smoother and reduce surface roughness, making the hot stamping effect more uniform and brighter; heating can also expand the paper fibers, increase the adsorption of the hot stamping material, and ensure that the hot stamping pattern is clearer and fuller; heating can make the adhesive on the paper surface more active, enhance the adhesion between the hot stamping material and the paper, and prevent the hot stamping pattern from falling off or fading; it can also reduce bubbles and plate sticking during the hot stamping process. Bubbles are usually caused by uneven evaporation of water on the paper surface or poor contact between the hot stamping material and the paper. Proper heating can solve these problems and ensure that the hot stamping effect lasts and does not change color; heating can even speed up the heat transfer speed during the hot stamping process, shorten the hot stamping time, and thus improve production efficiency; in addition, heating can also reduce the failure rate during the hot stamping process and reduce maintenance and downtime.

[0048] After the plurality of papers stacked in the first box 7 are heated and dried, if the papers are relatively humid before drying, the papers will be slightly deformed after drying. At this time, the two first sliders 27 can be controlled to move upward and reset in the corresponding first chute 20, driving the rotating plate 12 to move to Figure 1 After the state shown, the rotating plate 12 is controlled to rotate 90 degrees counterclockwise downward, so that the rotating plate 12 can enter the first box body 7 after rotating downward to a horizontal state, and the rotating plate 12 in a horizontal state is driven by the two first sliders 27 to slowly move downward inside the first box body 7, so that the rotating plate 12 at this time can be used as a pressing plate to press and shape the paper after heating and drying inside the first box body 7, and shape and remove the slight deformation of the paper after heating and drying, so as to facilitate the subsequent hot stamping of the paper;

[0049] At the same time, after the horizontal rotating plate 12 presses and shapes the papers inside the first box body 7, in order to prevent the multiple papers from sticking to each other after being squeezed, the above-mentioned step of the vertical rotating plate 12 driving the rubber pad 31 to rub against one end of the multiple papers can be repeated, so that the multiple papers with adhesion can be separated, avoiding the influence of paper adhesion on subsequent hot stamping processing, thereby improving the applicability of the rotating plate 12 and other components.

[0050] After the stacked multiple sheets of paper in the first box 7 are heated, dried and squeezed to shape, the telescopic ends of the multiple second electric telescopic rods 26 need to be controlled to extend upward together, so as to facilitate the rotation of the rotating plate 12 clockwise to the inside of the second box 8. Then, the rotating plate 12 can be controlled to rotate 90 degrees clockwise downward, so that the rotating plate 12 in a horizontal state enters the inside of the second box 8, and the two first sliders 27 move downward in the corresponding first slide grooves 20, so as to drive the rotating plate 12 to move synchronously downward in the second box 8 to abut against the tops of the two rectangular blocks 24, as shown in FIG. Figure 4As shown, the inner bottom surface of the first box body 7 is higher than the inner bottom surface of the second box body 8. At this time, the rotating plate 12 moves downward inside the second box body 8 to a state flush with the inner bottom surface of the first box body 7. With the help of the push plate 17 moving in the direction close to the second box body 8, the stacked papers can be pushed down to the top of the rotating plate 12 placed on the inner bottom surface of the second box body 8 at this time. With the help of the extension of the telescopic ends of the two first electric telescopic rods 25, the two limit plates 19 are located inside the second box body 8 and move in the direction of approaching each other, so that the two ends of the multiple papers stacked inside the second box body 8 are pushed and corrected, and then the two first sliders 27 and the two second sliders 23 can be used to move in the second box body 8. The corresponding first slide 20 and second slide 22 move slowly upward together, so that the rotating plate 12 and the stacked papers on the top thereof can move slowly upward inside the second box body 8, until the topmost paper moves to a position higher than the second box body 8, and then the paper is placed on the top of the conveyor belt 6 at the left end with the help of the automatic loading and unloading robot preset near the body 3, and the paper is transported to the top of the workbench 2 with the help of the conveyor belt 6, and the top of the paper is hot stamped by the hot stamping head 4. After the hot stamping, the paper is placed on the top of the conveyor belt 6 at the right end with the help of the robot, and the hot stamped paper is unloaded with the help of the conveyor belt 6 at the right end.

[0051] Since a detection mechanism and a cleaning mechanism are provided on the tops of the two horizontal plates 10, after the multiple sheets of paper in the first box body 7 are transferred to the second box body 8, the multiple industrial cameras 32 are used to automatically identify the impurities on the top of the sheets of paper. If impurities are found on the top of the sheets of paper, the two third sliders 33 can be synchronously controlled to drive the moving rod 28 and the rectangular strip 29 and other components to the top of the first box body 7 in the corresponding third slide groove 21, and the rectangular strip 29 can be controlled to rotate 90 degrees clockwise downward to drive the dust collector 39 to rotate to the bottom. After the top sheet of paper moves to the top of the second box body 8, the dust collector 39 is controlled to start, and the two third sliders 33 are used to move in the corresponding third slide groove 21 toward the direction close to the machine body 3, so that the dust collector 39 can automatically remove impurities on the top of the paper to be stamped during the movement, so as to avoid the impurities on the top of the paper from adversely affecting its own stamping process.

[0052] After the vacuum head 39 automatically removes impurities from the top of the paper, the appearance quality of the topmost paper can be detected with the help of multiple industrial cameras 32 at the bottom of the top plate 11. If the paper has no quality problems, it can be transferred to the top of the conveyor belt 6 at the left end by a preset robot and placed there, and then subjected to subsequent hot stamping processing; if the paper has quality problems, the rectangular strip 29 can be controlled to rotate and adjust, driving the two vacuum suction cups 35 to rotate to the bottom, and with the help of two fourth sliders 36, they can move downward synchronously inside the corresponding fourth slide groove 34, driving the two vacuum suction cups 35 to adsorb the smooth surface of the top of the paper, and then controlling the two third sliders 33 to move toward the left end inside the corresponding third slide groove 21, driving the adsorbed paper to move to the left side of the first box body 7, and controlling the two vacuum suction cups 35 to release the adsorption of the paper, so that the paper with quality problems is automatically removed and discharged, avoiding the problem of continuing to perform hot stamping processing on the paper with quality problems, which increases production costs;

[0053] At the same time, in order to prevent the staff from confusing the rejected paper with quality problems with other papers to be processed, after the two vacuum suction cups 35 adsorb and fix the top of the paper, the double-headed screw 37 can be controlled to rotate, driving the two moving blocks 38 and the vacuum suction cups 35 to move in a direction close to each other, so that the paper adsorbed by the vacuum suction cups 35 is bent and deformed, and the paper with quality problems can be automatically marked, which is convenient for subsequent staff to distinguish.
