Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of transfer paper making, in particular to a low-color-difference, interference-line-free, and non-plate-seam light column transfer paper making device and method. BACKGROUND

[0002] According to different mold pressing processes and mold pressing equipment, the non-plate-seam laser holographic mold pressing technology is divided into a cylinder plate non-plate-seam laser holographic mold pressing (single mold pressing plate roller) and a double-plate non-plate-seam laser holographic mold pressing (double mold pressing plate roller).

[0003] The double-plate non-plate-seam mold pressing is to realize the non-plate-seam laser holographic mold pressing by setting a low-temperature zone and a high-temperature zone on the mold pressing plate roller and through twice mold pressing technology by using two mold pressing stations. However, the cold and hot transition zone (heat transfer between high and low temperatures) is inevitably generated due to twice mold pressing, and then two bright difference zones (about 3-5 cm) are formed in the transition zone (the area with high temperature has high brightness, and the area with low temperature has low brightness). If the image to be mold pressed is a laser dot pattern, 3-5 points of brightness difference will be generated. If the light column pattern is mold pressed, not only 3-5 points of brightness difference will be generated, but also spiral lines similar to fingerprints (the surface of the holographic nickel plate 1 and 2 is too close) or diagonal interference lines (the surface of the holographic nickel plate 1 and 2 is too far apart) will be generated due to the characteristics of the plate surface. In the industry, the color difference of the cold and hot transition zone can be reduced by continuously optimizing the structure of the plate roller, but the diagonal interference lines cannot be eliminated.

[0004] To this end, a cylinder plate single-plate laser holographic mold pressing machine can be used to eliminate the interference lines. The plate surface will not appear the color difference of the cold and hot transition zone generated by double-plate mold pressing during mold pressing, and the printing color difference, spiral lines, and interference lines generated by the double-plate mold pressing alignment can be avoided. The core of this process is the preparation of the cylinder UV holographic plate.

[0005] In the fabrication of a cylindrical UV hologram, a sleeve needs to be fitted onto a molding roller. Rotation then replicates the pattern from the holographic column nickel plate onto the coated surface of the sleeve. During sleeve installation, one side of the molding roller must be suspended to ensure smooth sleeve placement. To ensure the sleeve rotates synchronously with the molding roller, a retaining ring and bolts are used to secure the sleeve to the roller. However, since the sleeve needs to be replaced each time a pattern is replicated, frequent disassembly and reassembly are required. Furthermore, multiple bolts are typically used for assembly and fixation to ensure the stability of the connection between the sleeve and the molding roller, making disassembly and reassembly quite difficult. The large size of the sleeve leads to a decrease in overall preparation efficiency. To address this, an air-expanding roller can be installed at the suspended end to lock the position of the sleeve. The sleeve can be quickly locked and released through simple inflation and deflation operations. However, the air-expanding roller cannot position the sleeve axially. If the sleeve is misaligned axially, it will inevitably cause deviation in pattern replication. Moreover, the air-expanding roller relies on friction for transmission. When the sleeve acts on the holographic light column nickel plate with a certain pressure, it also relies on friction for transmission. The interference between the two frictional forces can easily cause a phase difference between the sleeve and the molding roller, resulting in misaligned seams, uneven brightness, or interference patterns in the molded pattern.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.

[0023] In addition, elements in the present application can be referred to as "fixed" or "disposed" on another element, which can be directly on another element or can exist with a middle element. When an element is considered to be "connected" to another element, it can be directly connected to another element or can exist with a middle element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not the only implementation.

[0024] Please refer to Figures 1-12 In the embodiment of the present application, the low chromatic aberration interference fringe free and no-seam light column transfer paper making equipment comprises: a machine table 1, and a bearing table 2 fixed on the machine table 1, a sliding plate 3 is slidingly installed on the bearing table 2, and a support plate 4 is fixed on the sliding plate 3; further comprising: a rotating rod 5 rotatably installed on the support plate 4, a die plate roller 6 is fixed on the rotating rod 5, a sleeve pipe 7 is sleeved on the die plate roller 6, and a side plate 8 is fixed on the side end of the sleeve pipe 7; a let-in support assembly is arranged on the sliding plate 3, and a receiving plate 18 cooperating with the rotating rod 5 is connected to the let-in support assembly; a multi-direction positioning mechanism is arranged on the die plate roller 6 and connected with the receiving plate 18, and a rotation adjusting mechanism is arranged on the rotating rod 5; when the receiving plate 18 moves, the side plate 8 can be driven to rotate through the multi-direction positioning mechanism and the rotation adjusting mechanism, and the sleeve pipe 7 can be positioned through the side plate 8.

[0025] The machine table 1 is slidingly installed with a die flat plate 26, and the die flat plate 26 is electromagnetically adsorbed with a holographic light column nickel plate 27.

[0026] Specifically, when producing low-color-difference interference-free joint-free light column transfer paper, a cylindrical UV holographic plate needs to be made first. For this purpose, the corresponding holographic light column nickel plate 27 can be cut according to product requirements, and the holographic light column nickel plate 27 can be fixed on the mold pressing flat plate 26 by electromagnetic adsorption. At the same time, under the action of the accommodation supporting assembly, the supporting plate 18 and the multidirectional positioning mechanism are in a separated state, so that the multidirectional positioning mechanism and the rotary adjusting mechanism are moved to be out of position with the sleeve 7. At this time, the corresponding sleeve 7 can be sleeved on the mold pressing plate roller 6. Under the action of the accommodation supporting assembly, the supporting plate 18 is in abutment with the multidirectional positioning mechanism to support the rotating rod 5. At the same time, the supporting plate 18 also drives the multidirectional positioning mechanism and the rotary adjusting mechanism to move, so as to position and lock the sleeve 7 in the horizontal direction through the side plate 8, and lock the angle of the sleeve 7 in the circumferential direction through the side plate 8, so that the sleeve 7 can rotate synchronously with the mold pressing plate roller 6 and always maintain a coaxial state. In this way, when the mold pressing plate roller 6 translates and rotates subsequently, the sleeve 7 can also move synchronously, so that when the sleeve 7 contacts the holographic light column nickel plate 27, the mold pressing flat plate 26 is controlled to translate in the vertical direction to copy the image on the holographic light column nickel plate 27 to the UV coating on the surface of the sleeve 7. When the image copying is completed, the mold pressing plate roller 6 is controlled to reset, and the accommodation supporting assembly controls the supporting plate 18 to accommodate again, so that the multidirectional positioning mechanism and the rotary adjusting mechanism are separated from the side plate 8. At this time, the sleeve 7 is taken out, and the next sleeve 7 is replaced. The above steps are repeated to prepare a plurality of required cylindrical UV holographic plates.

[0027] Please refer to Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 , the accommodation supporting assembly comprises a supporting sleeve 16 fixed on the sliding plate 3, a supporting rod 17 fixedly connected with the supporting plate 18 is axially slidably arranged in the supporting sleeve 16, a connecting plate 19 is fixed on the supporting rod 17, and a gas cylinder 20 fixedly connected with the connecting plate 19 is fixed on the sliding plate 3.

[0028] Please refer to Figures 1-10The multi-direction positioning mechanism comprises a rotating sleeve 9 rotatably mounted on the mold plate roller 6 and sleeved on the rotating rod 5, a rotating disc 10 fixed on the rotating sleeve 9, and a plurality of slide grooves 1001 circumferentially and equidistantly formed on the rotating disc 10; further comprising an elastic pushing assembly and a limiting assembly arranged on the side plate 8 and connected with the slide grooves 1001, the elastic pushing assembly comprising a sliding block 11 slidably mounted in the slide groove 1001, a sliding sleeve 13 axially sliding on the rotating sleeve 9, a hinge rod 15 hingedly connected with the sliding block 11 and arranged on the sliding sleeve 13, a third spring 28 sleeved on the rotating sleeve 9, two ends of the third spring 28 abutting against the sliding sleeve 13 and the rotating disc 10 respectively, the elastic pushing assembly further comprising a first conical ring 21 axially sliding on the rotating sleeve 9, a guide plate 14 fixed on the sliding sleeve 13, a guide column 22 fixed on the first conical ring 21 and penetrating through the guide plate 14, a limiting ring 2201 fixed on the end of the guide column 22 and abutting against the guide plate 14, a first spring 23 sleeved on the rotating sleeve 9, two ends of the first spring 23 abutting against the first conical ring 21 and the guide plate 14 respectively, and the limiting assembly comprising a plurality of oblique guide grooves 801 and straight grooves 802 circumferentially and equidistantly formed on the side plate 8, and a limiting plate 12 fixed on the sliding block 11 and matched with the oblique guide grooves 801 and the straight grooves 802.

[0029] Please refer to Figures 1-5 、 Figures 7-9 、 Figure 11 , the rotating adjusting mechanism comprises a second conical ring 24 axially sliding on the rotating sleeve 9, a fixed ring 902 fixed on the end of the rotating sleeve 9, a second spring 25 sleeved on the rotating sleeve 9, two ends of the second spring 25 abutting against the second conical ring 24 and the fixed ring 902 respectively, and the rotating adjusting mechanism further comprising a clamping groove 901 formed on the circumferential outer wall of the rotating sleeve 9, a helical groove 501 formed on the circumferential outer wall of the rotating rod 5, and a limiting block 2401 fixed on the inner wall of the second conical ring 24 and slidably embedded in the clamping groove 901 and the helical groove 501.

[0030] In detail, the stamper roller 6 is fixed with a support ring near one end of the support plate 4, which is used to limit the maximum sleeve amount of the sleeve 7. In order to ensure that the sleeve 7 can be smoothly sleeved on the stamper roller 6, it is necessary to make one end of the stamper roller 6 in a suspended state. For this purpose, before the sleeve 7 is assembled, the air cylinder 20 controls the support rod 17 to be located at the end of the stroke towards the inside of the support sleeve 16 through the connecting plate 19, so that the receiving plate 18 is separated from the rotating sleeve 9; in this state, the first conical ring 21, the sliding sleeve 13 and the guide plate 14 are located at the end of the stroke away from the rotating disc 10, and the distance between the guide plate 14 and the first conical ring 21 is maximum, so that the limiting ring 2201 abuts against the guide plate 14. Under the action of the sliding sleeve 13, a plurality of sliding blocks 11 are controlled by the hinged rod 15 to be located at the end of the stroke on one side of the sliding groove 1001, and the distance between the plurality of sliding blocks 11 is minimum, so that the distance between the limiting plates 12 is also minimum, and the distance from the end of the limiting plate 12 to the center of the rotating rod 5 is smaller than the radius of the stamper roller 6. The elongation of the first spring 23 in the natural state is greater than the maximum distance between the sliding sleeve 13, the guide plate 14 and the first conical ring 21, and the elongation of the third spring 28 in the natural state is greater than the maximum distance between the sliding sleeve 13 and the rotating disc 10. For this purpose, the first spring 23 and the third spring 28 are both in a pre-compressed state, and the elastic potential of the first spring 23 is much greater than that of the third spring 28. For this purpose, the third spring 28 always provides a pushing force to the sliding sleeve 13 in the direction away from the rotating disc 10, and the first spring 23 always provides a pushing force to the first conical ring 21 in the direction away from the rotating disc 10; Similarly, the distance between the second conical ring 24 and the fixed ring 902 is maximum, so that the limiting block 2401 is located at the end of the stroke away from the fixed ring 902 on one side of the clamping groove 901 and the spiral groove 501, and the elongation of the second spring 25 in the natural state is greater than the maximum distance between the second conical ring 24 and the fixed ring 902. For this purpose, the second spring 25 is in a pre-compressed state, and always provides a pushing force to the second conical ring 24 in the direction away from the fixed ring 902.At this time, the sleeve 7 can be sleeved on the die plate roller 6, and one end of the sleeve 7 is in abutment with the supporting ring. After the sleeve 7 is sleeved, in order to ensure that the sleeve 7 can rotate synchronously with the die plate roller 6, the sleeve 7 needs to be limited. For this purpose, under the action of the air cylinder 20, the supporting rod 17 is driven to move away from the supporting sleeve 16 through the connecting plate 19, so as to drive the supporting plate 18 to move. When the supporting plate 18 moves to the position in abutment with the first tapered ring 21 and the second tapered ring 24, the first tapered ring 21 is driven to move towards the rotating disc 10. Since the elastic potential energy of the first spring 23 is greater than that of the third spring 28, the first tapered ring 21 will push the guide plate 14 and the sliding sleeve 13 to slide along the axis of the rotating rod 5 through the first spring 23, so as to control the sliding block 11 to slide along the sliding groove 1001 through the hinged rod 15. The sliding block 11 will also drive the plurality of limiting plates 12 to move away from each other. The supporting plate 18 will also control the second tapered ring 24 to move towards the fixed ring 902 and compress the second spring 25. The second tapered ring 24 will also drive the limiting block 2401 to slide along the clamping groove 901, and under the action of the spiral groove 501, the rotating sleeve 9 is rotated, so as to drive the rotating disc 10 to rotate. Please refer to; Figures 5-7, further, the side of the limiting plate 12 towards the rotating disc 10 is formed with a wedge-shaped groove 1201, when the plurality of limiting plates 12 move away from each other, if the limiting plate 12 is located at the matching position of the inclined guide groove 801, the limiting plate 12 will smoothly enter the inclined guide groove 801, and under the action of the wedge-shaped groove 1201, even if the sleeve 7 does not completely abut against the supporting ring, the sleeve 7 can be first pushed to abut against the supporting ring by the limiting plate 12, in this way, during the radial locking process, the wedge-shaped groove 1201 automatically generates an axial force, ensuring that the sleeve 7 can always be pushed to the preset position, eliminating the axial installation gap, ensuring the positioning accuracy, and during the opening process of the limiting plate 12, it will abut against one of the inclined surfaces of the inclined guide groove 801, the cooperation between the limiting plate 12 and the inclined surface of the inclined guide groove 801 generates a circumferential rotating force on the side plate 8 and the sleeve 7, under the action of the force, the sleeve 7 rotates to make room, to ensure that the limiting plate 12 can smoothly enter the straight groove 802 through the inclined guide groove 801, if the limiting plate 12 is located at the misaligned position of the inclined guide groove 801, that is, the limiting plate 12 abuts against the inner wall of the side plate 8, under the action of the side plate 8, the position of the limiting plate 12 no longer changes, and when the first conical ring 21 continues to move, it will compress the first spring 23, at the same time, since the limiting block 2401 always slides along the spiral groove 501, the rotating sleeve 9 is always in a rotating state, thereby driving the limiting plate 12 to rotate around the rotating rod 5 through the rotating disc 10, so that the limiting plate 12 moves towards the inclined guide groove 801, until the limiting plate 12 enters the inclined guide groove 801, at this time, the first spring 23 is elastically released to push the limiting plate 12 to move, that is, the plurality of limiting plates 12 perform the opening action, and when the limiting plate 12 moves vertically to the axial direction of the rotating rod 5, it abuts against the inclined surface of the inclined guide groove 801, thereby providing a circumferential rotating force on the side plate 8 and the sleeve 7, so that the sleeve 7 is also passively rotated to make room, until the end of the limiting plate 12 enters the straight groove 802, under the action of the limiting plate 12 and the straight groove 802, the position of the sleeve 7 in the axial direction of the mold plate roller 6 is locked, and the angle of the sleeve 7 in the circumferential direction is locked, and it is ensured that the sleeve 7 always moves synchronously with the mold plate roller 6; when the sliding block 11 moves to the end of the stroke away from the rotating sleeve 9 side of the sliding groove 1001, the sliding sleeve 13 and the guide plate 14 no longer move, at this time, the first conical ring 21 continues to move and compresses the first spring 23, until the first conical ring 21 abuts against the guide plate 14, the receiving plate 18 also moves to the abutting position of the rotating sleeve 9, the first conical ring 21 no longer moves, and the position of the guide plate 14 is locked, and under the action of the receiving plate 18, the rotating sleeve 9 is supported to prevent the mold plate roller 6 and the sleeve 7 from shaking due to insufficient support when the rotating rod 5 rotates.
