[0001] The invention belongs to the technical field of hot stamping plate rollers, in particular to a device for heating the arc surface of a hot stamping plate roller. Background Art

[0002] The hot stamping process uses the principle of heat transfer to transfer the aluminum layer in the electroplated aluminum to the surface of the substrate to form a special metallic effect. Since the main material used for hot stamping is electroplated aluminum foil, hot stamping is also called electroplated aluminum hot stamping. The hot stamping roller is mainly used for hot printing on the surface of paper, plastic, and cloth. The hot stamping roller is a pressure roller, and a mold that adapts to the arc surface is installed on the surface of the pressure roller. During the embossing process, the pressure roller needs to be heated.

[0003] The existing hot stamping process is to directly pressurize the hot stamping object through the curved printing plate, so as to obtain the pattern required for hot stamping on the outer surface of the object. However, when the plate used for printing involves a curved structure, it needs to be specially customized. Otherwise, the printed pattern will be uneven in depth during the stamping process, which leads to the following problems:

[0004] 1. The cost of printing curved surfaces is high, and a plate with a shape complementary to the printed curved surface needs to be specially customized, resulting in poor versatility of the device;

[0005] 2. The printing surface needs to be replaced, so the parts used for printing must be detachable structures, and the internal volume will change. Therefore, when the hot stamping device supplies hot oil to the printing end, it is easy to have insufficient hot oil supply. Summary of the invention

Under normal circumstances, the segmented slide plate is set at a position slightly above the inner push ball, so when the segmented slide plate rotates with the printing cylinder, it will move in the direction of fitting the inner push ball; when the segmented slide plate is not in contact with the inner push ball, it will not be pushed by the inner push ball to the side of the inner wall of the printing cylinder, and it will be stretched and reset by the tension spring belt.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. The roller printing device used for hot stamping printing of the device is a rolling cylindrical structure as a whole, so it can perform perfect rolling printing on the curved hot stamping surface and is not affected by the curvature of the hot stamping surface, so that the hot stamping surface that can be printed by the device has high versatility, and it can work normally without the need to specially customize the roller printing device that conforms to the curved hot stamping surface;

[0015] 2. In order to ensure that the force exerted on the curved gilded surface by the printing roller is always kept at a fixed strength when it rolls along the curved gilded surface, double rotating pressure columns capable of sensing pressure are set on both sides. According to the advancing distance of the inner sliding push plate, the advancing distance of the segmented traction arm is adjusted synchronously, thereby ensuring that the printing roller always fits the curved gilded surface with a fixed strength, avoiding the problem of the printed gilded pattern being too dark or too shallow;

[0016] 3. When stamping, it is difficult to achieve stamping only by the rolling friction between the stamping surface and the printing roller. The friction may be too small, resulting in the problem that the printing roller cannot roll synchronously. Therefore, a torsion motor is added inside the printing roller to enable the printing roller to rotate actively, reduce the influence of friction resistance, and avoid slipping problems;

[0017] 4. Due to the small diameter of the heat-resistant hose, the liquid hot oil will cause a large pressure on the inner wall of the heat-resistant hose, thereby applying pressure to the pressure-sensitive push plate. Therefore, according to the pressure feedback from the pressure-sensitive push plate, the melt flow through the inserted long rod can be judged, and then the pressurization effect of the internal pressure slide can be adjusted to avoid the problem of insufficient heat supply due to too little total amount of liquid hot oil supplied, and also to avoid the problem of hot oil reflux and overflow due to excessive supply of hot oil.

[0028] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0029] Example 1, please refer to Figure 1-Figure 5 The present invention provides a technical solution: a curved surface heating device for a hot stamping plate roller, comprising two roller printing devices 4, which can perform hot stamping printing on the curved surface by rolling printing; a suspension component 1, which can push the roller printing device 4 below to adjust the distance between it and the hot stamping surface; a pressure probe device 2, which is clamped at the bottom of the suspension component 1 and can accurately control the pressure between the roller printing device 4 and the hot stamping surface; a braking device 3, which can protect the outer surface of the roller printing device 4 to a certain extent and control the roller printing device 4 to stop rotating.

[0030] The detection and pressure device 2 includes a storage bin 21, a large amount of liquid hot oil can be temporarily added to the interior of the storage bin 21 to provide sufficient heat for the roller printing device 4; a side sleeve 22, the number of the side sleeves 22 is two, and one side of the outer surface of the side sleeve 22 is fixedly connected to one end of the storage bin 21; an inner sliding push plate 23, the outer surface of the inner sliding push plate 23 is slidably connected to the inner wall of the side sleeve 22, and the top of the inner sliding push plate 23 is slidably connected with a detection and pressure element; a side support plate 24, the top of the side support plate 24 is fixedly connected to the middle of the lower surface of the inner sliding push plate 23; a double rotation and pressure column 25, the middle part of the inner wall of the double rotation and pressure column 25 is fixedly connected to the bottom end of the side support plate 24 through a connecting shaft, and the left and right sides of the outer surface of the double rotation and pressure column 25 are pressed against the hot stamping surface.

[0031] The storage bin 21 includes a heat-insulating long tube 211, which can keep the liquid hot oil stored inside warm and play a heat-insulating role; a liquid infusion branch tube 213, the number of which is three, and the front end of which is fixedly connected to the inner cavity of the heat-insulating long tube 211 through a through-hole, and the external liquid hot oil can be directly transported to the inside of the heat-insulating long tube 211 through the liquid infusion branch tube 213; an internal pressure slide plate 212, the number of which is two, one side of the outer surface of the internal pressure slide plate 212 is fixedly connected to one end of the inner wall of the heat-insulating long tube 211, and the other side of the outer surface of the internal pressure slide plate 212 is slidably connected to the inner wall of the heat-insulating long tube 211. The internal pressure slide plates 212 on both sides can actively extend, thereby pressurizing the liquid hot oil inside the heat-insulating long tube 211, so that the liquid hot oil is discharged downward.

[0032] The suspension component 1 includes a strip movable plate 11, the top of which is slidably connected to a guide horizontal rod 15 through a column slide plate 13, and the left and right sides of the lower surface of the strip movable plate 11 are fixedly connected to the middle of the inner cavity of the side sleeve 22 through a connecting wire 26; an embedded roller 12, the number of which is two, and the outer surface of the embedded roller 12 is rollingly connected to the outer surface of the guide horizontal rod 15, and the outer surface of the embedded roller 12 is rollingly connected to the top of the inner cavity of the strip movable plate 11; a segmented traction arm 14, the top of the segmented traction arm 14 is fixedly connected to the axis of the bottom of the inner cavity of the strip movable plate 11, the bottom end of the segmented traction arm 14 is fixedly connected to the middle of the outer surface of the insulation long tube 211, and a corresponding sensing component is provided inside the strip movable plate 11, and the propulsion movement of the segmented traction arm 14 can be controlled according to the electrical signal output by the connecting wire 26.

[0033] The device is used to perform hot stamping processing on the curved surface structure. The hot stamping surface is placed on the table facing the roller printing device 4, and then the strip movable plate 11 controls the bottom end of the segmented traction arm 14 to extend downward, and the roller printing device 4 moves to the side close to the hot stamping surface. Since the double-rotation pressure column 25 pushed by the side support plate 24 in the initial position is lower, the double-rotation pressure column 25 will first contact the hot stamping surface, and then be pushed to the side close to the side sleeve 22 under the extrusion action, and the sliding distance of the inner sliding push plate 23 is monitored. When the roller printing device 4 is just squeezed with the hot stamping surface, the segmented traction arm 14 will no longer advance, thereby fixing the pushing distance of the side support plate 24.

[0034] The platform that lifts and fixes the hot stamping surface slides forward and backward relative to the device, so that the roller printing device 4 can sweep the entire hot stamping surface. Since the hot stamping surface is a curved surface structure, when the hot stamping surface moves, the double-rotating pressure columns 25 on both sides will be dislocated in the vertical direction relative to the hot stamping surface. When the hot stamping curved surface pushes the double-rotating pressure columns 25 upward, the sliding distance of the inner sliding push plate 23 is further increased. At this time, the inner sliding push plate 23 moves upward, and transmits the electrical signal of the upward sliding distance to the strip moving plate 11 through the connecting wire 26. Then, through the feedback regulation of the strip moving plate 11, the segmented traction arm 14 is synchronously pulled up to the same height, so that the roller printing device 4 and the curved hot stamping surface always maintain a fixed extrusion pressure;

[0035] Similarly, when the hot stamping arc surface gradually tends to separate from the double-rotation pressure column 25 while moving, in order to ensure that the double-rotation pressure column 25 is always in contact with the hot stamping surface, the inner sliding push plate 23 at this time will push the double-rotation pressure column 25 downward, and then the strip moving plate 11 will synchronously push the segmented traction arm 14 according to the sliding height of the inner sliding push plate 23, and descend to the same height so that the roller printing equipment 4 and the arc-shaped hot stamping surface always maintain a fixed extrusion pressure.

[0036] As the roller printing device 4 rolls back and forth along the hot stamping surface, the imprint on the outer surface is hot stamped on the hot stamping surface in a fixed shape, completing the hot stamping heating work.

[0037] The device actually performs hot stamping processing with only two roller printing devices 4, but the strip-shaped movable plate 11 can perform directional sliding movement along the guide horizontal rod 15 through the embedded rollers 12 on both sides, so the actual stamping range of the roller printing device 4 can meet daily work needs.

[0038] Example 2, please refer to Figure 1-Figure 9The present invention provides a technical solution: on the basis of embodiment 1, the roller printing device 4 includes a printing roller 41, the number of the printing rollers 41 is two, and the outer surface of the printing roller 41 is provided with a card slot, and the liquid hot oil located on the inner wall of the printing roller 41 will transfer the heat to the outer surface of the printing roller 41; an inner rotating drum 42, the left and right sides of the inner rotating drum 42 are rotatably connected to the axis of the inner wall of the printing roller 41 through a transfer groove, and the front and rear sides of the inner cavity of the inner rotating drum 42 are symmetrically provided with discharge pipes 43, and the discharge pipe 43 extends to the inner cavity of the printing roller 41 away from the end of the inner rotating drum 42; a torsion motor 45, the outer surface of the output shaft of the torsion motor 45 is fixedly connected with a clamping disk 46, and the inner wall of the clamping disk 46 is connected to the axis of the outer surface of the printing roller 41 through a through-hole. Fixed connection; a segmented slide 47, the left and right ends of the segmented slide 47 are fixedly connected to the axis of the inner wall of the printing cylinder 41 through a tension spring belt 48; an inner push ball 44, the outer surface of the inner push ball 44 is rollingly connected to the middle part of the outer surface of the inner rotating cylinder 42 through an embedded groove, a mold 49, the number of the molds 49 is two, and the inner wall of the mold 49 is clamped with the outer surface of the printing cylinder 41 through a slot. Under normal circumstances, the segmented slide 47 is set at a position slightly above the inner push ball 44, so when the segmented slide 47 rotates with the printing cylinder 41, it will move in the direction of fitting the inner push ball 44; when the segmented slide 47 is not in contact with the inner push ball 44, it will not be pushed by the inner push ball 44 to the side of the inner wall of the printing cylinder 41, and it will be stretched and reset by the tension spring belt 48.

[0039] The braking device 3 includes a connecting bottom shell 31, the bottom of which is fixedly connected to a diversion device 5, and the top of the connecting bottom shell 31 is fixedly connected to the middle of the lower surface of the thermal insulation long tube 211; a side wing baffle 33, the number of which is two, and the end of the side wing baffle 33 is slidably connected to one side of the outer surface of the connecting bottom shell 31 through a vertical slide groove, and the inner cavity of the side wing baffle 33 is evenly provided with a compression sleeve 34, the side wing baffle 33 is a hollow plate body, when the side wing baffle 33 slides up along the connecting bottom shell 31, the slide groove space inside the connecting bottom shell 31 is squeezed, and then the inside of the side wing baffle 33 is pressurized through the hollow mouth of the end of the side wing baffle 33, and the compression sleeve 34 is pushed downward; a vertical guide tube 32, the top end of the vertical guide tube 32 is fixedly connected to the axis center of the bottom of the inner cavity of the thermal insulation long tube 211 through a through-hole.

[0040] The diversion device 5 includes an inserted long rod 51, the left and right ends of the inserted long rod 51 are respectively fixedly connected to the bottom ends of the torsion motors 45 on both sides, and both sides of the inner cavity of the inserted long rod 51 are fixedly connected to the end of the discharge pipe 43 away from the internal rotating cylinder 42 through the socket, and the bottom end of the vertical guide tube 32 is fixedly connected to the axis of the inner cavity of the inserted long rod 51; a heat-resistant hose 52, the number of the heat-resistant hoses 52 is two, and the two ends of the heat-resistant hose 52 are fixedly connected to the inner wall of the inserted long rod 51; a pressure-sensitive push plate 53, the bottom end of the pressure-sensitive push plate 53 is fixedly connected to the inner wall of the inserted long rod 51, and the top end of the pressure-sensitive push plate 53 and the outer surface of the heat-resistant hose 52 are squeezed against each other.

[0041] When performing stamping work, it is difficult to achieve stamping work only by the rolling friction between the stamping surface and the printing roller 41. The friction may be too small, resulting in the problem that the printing roller 41 cannot roll synchronously. Therefore, a torsion motor 45 is added inside the printing roller 41 to enable the printing roller 41 to rotate actively, reduce the influence of friction resistance, and avoid slipping problems.

[0042] The torsion motor 45 drives the outer shell of the printing cylinder 41 to rotate through the clamping plate 46. Since the internal rotating cylinder 42 always remains in a relatively static state under the limiting action of the discharge pipes 43 on both sides and the long rod 51 inserted at the axis, the printing cylinder 41 will drive the segmented slide plate 47 on the inner wall to pass through the inner push ball 44 when rotating, so that the segmented slide plate 47 will continue to shake along the inner wall of the printing cylinder 41 under the tension of the tension spring belt 48 and the thrust of the inner push ball 44, so as to further stir the liquid hot oil inside the printing cylinder 41 evenly, thereby ensuring that the hot oil can continuously supply heat.

[0043] The side baffle 33 can cover the upper part of the outer surface of the printing roller 41 to prevent the printing roller 41 from contacting external objects. When the hot stamping of the printing roller 41 is completed, the segmented traction arm 14 will pull the braking device 3 upward. At this time, the pressurized gas connected to the inside of the bottom shell 31 will pass through the inner cavity of the side baffle 33 and be delivered to each compression sleeve 34. After the compression sleeve 34 is extended, it will be squeezed and contacted with the printing roller 41 below, and the printing roller 41 will be prevented from further rotation through friction, and the mold 49 on the outer surface of the printing roller 41 will be peeled off.

[0044] The diversion device 5 supplies liquid hot oil to the inside of the printing rollers 41 on both sides. When the liquid hot oil passes through the heat-resistant hose 52, due to the small diameter of the heat-resistant hose 52, the liquid hot oil will cause a large pressure on the inner wall of the heat-resistant hose 52, thereby applying pressure to the pressure-sensitive push plate 53. Therefore, based on the pressure feedback from the pressure-sensitive push plate 53, the hot oil flow through the inserted long rod 51 can be determined, and then the pressurization effect of the internal pressure slide plate 212 can be adjusted.

[0045] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
