[0001] The present invention relates to the technical field of leather hot stamping, and particularly to a hot stamping machine for in-vehicle leather processing with quick switching. Background Art

[0002] Hot stamping (also known as thermal hot stamping or hot foil stamping) of in-vehicle leather is a common decorative process widely used in automotive interiors, especially in high-end models and customized vehicles. Through hot stamping, various patterns, logos, textures and other elements can be added to the leather surface, thereby enhancing the aesthetics and uniqueness of the interior.

[0003] Currently, when using a hot stamping machine to hot stamp in-vehicle leather, first control the hot stamping plate to apply a certain pressure downward so that the text or pattern on the hot stamping plate is hot stamped on the leather, then control the hot stamping plate to lift upward, then control the hot stamping plate to move away, then control the ink printing plate to move to the ink cartridge, then control the ink printing plate to dip ink downward, then lift the ink printing plate, then control the ink printing plate to move above the leather hot stamping mark, then press down the ink printing plate so that the ink mark is pressed on the leather hot stamping mark, then lift the ink printing plate, and then control the ink printing plate to move away. In this way, the hot stamping of in-vehicle leather is completed.

[0004] It can be seen that the above-mentioned processes are numerous and the steps are cumbersome. In order to reduce the operation steps, the present invention provides a hot stamping machine for in-vehicle leather processing with quick switching. Summary of the Invention

[0005] In order to overcome the disadvantages of the existing hot stamping machine with numerous processes and cumbersome steps, the present invention provides a hot stamping machine for in-vehicle leather processing with quick switching.

On both sides of the frame, cylinders symmetrically distributed along the frame are fixedly connected. A sliding frame is slidably connected inside the frame. A connecting frame is fixedly connected to the cylinder, and the connecting frame is fixedly connected to the sliding frame. A storage box is slidably connected to the sliding frame. The bottom of the storage box is in contact with a roller shaft in a rotational connection manner. On both sides of the sliding frame, first sliders symmetrically distributed along the sliding frame are slidably connected. The roller shaft is rotatably connected to the first slider. A heating roller is rotatably connected to the bottom of the sliding frame. The convex surface of the heating roller is in extrusion fit with the roller shaft. A hot stamping plate is fixedly connected to one side of the heating roller. On the other side of the heating roller opposite to the hot stamping plate, a heat insulation plate is fixedly connected. An ink printing plate is inserted into the heat insulation plate, and the ink printing plate is in contact with the roller shaft through the rotation of the heating roller.

[0007] In addition, particularly preferably, a motor is further included. The motor is fixedly connected to one side of the sliding frame, and the output shaft of the motor is fixedly connected to the heating roller.

[0008] In addition, it is particularly preferred that a first gear is further included, the first gear is fixedly connected to the heating roller, a second gear is fixedly connected to one side of the roller shaft close to the first gear, and the second gear meshes with the first gear.

[0009] In addition, it is particularly preferred that the diameter of the second gear is smaller than that of the first gear.

[0010] In addition, it is particularly preferred that the transmission ratio of the first gear to the second gear is 1.5:1.

[0011] In addition, it is particularly preferred that telescopic rods symmetrically distributed along the sliding frame are further included, the telescopic rods are fixedly connected to the sliding frame, the telescopic rods are fixedly connected to the first slider adjacent to the same side, a pushing block is fixedly connected to the first slider, cams symmetrically distributed along the heating roller are fixedly connected to the heating roller, the cams are in pressing fit with the adjacent pushing blocks, and the concave surface of the cam is close to the side of the ink plate.

[0012] In addition, it is particularly preferred that a first spring is further included, the first spring is fixedly connected to the adjacent connecting frame, a pressing frame is slidably connected to the telescopic rod of the air cylinder, the pressing frame is fixedly connected to the adjacent first spring, the pressing frame is slidably connected with second sliders symmetrically distributed along the pressing frame through inclined grooves, the machine frame is slidably connected with third sliders corresponding to the second sliders, and the third sliders are located directly below the corresponding second sliders.

[0013] In addition, it is particularly preferred that a fixed nozzle is further included, the fixed nozzle is fixedly connected to the sliding frame, the outlet of the fixed nozzle faces downward the heating roller, an air pump is fixedly connected to one side of the machine frame close to the fixed nozzle, and the air pump is communicated with the fixed nozzle.

[0014] In addition, it is particularly preferred that a lifting frame is further included, the lifting frame is slidably connected to the machine frame, the lifting frame protrudes from the hot stamping table surface of the machine frame, and at least one second spring is fixedly connected between the lifting frame and the machine frame.

[0015] The beneficial effects of the present invention are as follows: By controlling the telescopic movement of the air cylinder back and forth twice and controlling the intermittent rotation of the motor by 180 degrees, the hot stamping operation of the leather can be completed, significantly shortening the hot stamping process, reducing the hot stamping steps, and accelerating the hot stamping process of the leather.

[0016] The present invention drives the roller shaft to rotate through the heating roller, so as to achieve the effect of assisting the rotation of the roller shaft, enabling the roller shaft to uniformly discharge ink and preventing the situation that the roller shaft cannot rotate and discharge ink due to slipping.

[0017] Through the transmission ratio between the first gear and the second gear, the rotation speed of the roller shaft is 1.5 times that of the heating roller in the present invention. Thus, within the same time, more ink is evenly applied to the printing ink plate, avoiding insufficiently applied ink, which may lead to a lighter hot stamping on the leather.

[0018] Through the cooperation of the pushing block and the cam in the present invention, the roller shaft only discharges ink downward when the printing ink plate rotates to the top, and no ink is discharged during other periods, avoiding ink from contaminating the heating roller.

[0019] During the descending process of the present invention, first, the four corners of the leather are respectively clamped and pulled outward by the four second sliders and the adjacent third sliders, keeping the leather under tension, and then hot stamping or inking operations are performed on the leather, which helps to ensure that patterns, characters, or ink can be accurately transferred to the substrate, reducing the risk of deviation and misalignment, and thus improving the clarity and detail performance of the hot stamping.

[0020] During the rotation process of the present invention, by starting the air pump, the heating roller and the hot stamping plate are blown to be cleaned, preventing excess ink from contaminating the heating roller and the hot stamping plate.

[0021] When the hot stamping plate presses downward on the leather in the present invention, the leather bulges upward through the lifting frame and the buffering effect of the second spring, avoiding the non - stamping area from being sunken and deformed downward. Description of the Drawings

Detailed implementation manners

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Embodiment 1: A vehicle leather processing stamping machine with quick switching, as Figures 1 - 5As shown in the figure, it includes a machine frame 101. At the lower part of the machine frame 101, air cylinders 102 symmetrically distributed left and right along the machine frame 101 are fixedly connected. At the upper part of the machine frame 101, a sliding frame 103 is slidably connected in the up and down direction. The telescopic end of the air cylinder 102 is fixedly connected with a connecting frame 1031, and the connecting frame 1031 is fixedly connected with the sliding frame 103. At the upper part of the sliding frame 103, an ink storage box 104 is slidably connected in the up and down direction. Ink is stored in the ink storage box 104. The bottom of the ink storage box 104 is in contact with a roller shaft 105 in a rotating manner. The sliding frame 103 is slidably connected with first sliders 106 symmetrically distributed left and right along the sliding frame 103 in the up and down direction. The roller shaft 105 is rotatably connected with the first sliders 106. At the bottom of the sliding frame 103, a heating roller 107 is rotatably connected. The convex surface of the heating roller 107 is in extrusion fit with the roller shaft 105. On the right side of the sliding frame 103, a motor is fixedly connected. The output shaft of the motor is fixedly connected with the right end of the heating roller 107. At the lower side of the heating roller 107, a hot stamping plate 108 is fixedly connected. At the upper side of the heating roller 107, a heat insulation plate 109 is fixedly connected. An ink printing plate 110 is inserted into the heat insulation plate 109, and the ink printing plate 110 is in contact with the roller shaft 105.

[0036] When using this hot stamping machine to perform hot stamping on leather, first place the leather on the hot stamping tabletop of the machine frame 101 so that the hot stamping part is directly below the hot stamping plate 108. Then, control the telescopic rod of the air cylinder 102 to shorten downward. The telescopic rod of the air cylinder 102 drives the sliding frame 103 to slide downward along the machine frame 101 through the connecting frame 1031. The sliding frame 103 drives the ink storage box 104, the roller shaft 105, the first sliders 106, the heating roller 107, the hot stamping plate 108, the heat insulation plate 109, and the ink printing plate 110 to move downward as a whole. The hot stamping plate 108 applies a certain pressure downward on the leather, so that the text or pattern on the hot stamping plate 108 is hot stamped on the leather. Then, control the telescopic rod of the air cylinder 102 to extend upward to reset, so that the connecting frame 1031, the sliding frame 103, the ink storage box 104, the roller shaft 105, the first sliders 106, the heating roller 107, the hot stamping plate 108, the heat insulation plate 109, and the ink printing plate 110 are lifted upward as a whole.

[0037] Then, control the motor to drive the heating roller 107 to rotate 180 degrees, so that the hot stamping plate 108 and the ink printing plate 110 are interchanged. During this process, when the ink printing plate 110 rotates, it drives the roller shaft 105 to rotate through friction, so that the ink in the ink storage box 104 is automatically fed onto the surface of the roller shaft 105. The roller shaft 105 then brushes the ink onto the ink printing plate 110. When the convex surface of the heating roller 107 rotates to contact the roller shaft 105, the convex surface of the heating roller 107 squeezes the roller shaft 105 to move upward, so that the ink storage box 104 and the first sliders 106 move upward as a whole. When the plane of the hot stamping plate 108 rotates 180 degrees to the directly above, under the action of gravity, the roller shaft 105, the ink storage box 104, and the first sliders 106 move downward as a whole.

[0038] Next, the telescopic rod of the air cylinder 102 is controlled to shorten downward again, so that the ink printing plate 110 moves downward, thereby inking the hot stamping mark on the leather. After the inking is completed, the telescopic rod of the air cylinder 102 is controlled to extend upward and reset. In this way, the hot stamping operation of the leather can be completed, significantly shortening the hot stamping process, reducing the hot stamping steps, and accelerating the hot stamping process of the leather.

[0039] As Figures 6 - 7 shown, it further includes a first gear 201. The first gear 201 is fixedly connected to the right part of the heating roller 107. A second gear 202 is fixedly connected to the right side of the roller shaft 105. The second gear 202 meshes with the first gear 201. The diameter of the second gear 202 is smaller than that of the first gear 201. The transmission ratio of the first gear 201 to the second gear 202 is 3:2. Telescopic rods 203 symmetrically distributed left and right along the sliding frame 103 are fixedly connected to the upper part of the sliding frame 103. The telescopic ends of the telescopic rods 203 are fixedly connected to the adjacent first slider 106 on the same side. A pushing block 205 is fixedly connected to the lower side of the first slider 106. Cam 204 symmetrically distributed left and right along the heating roller 107 is fixedly connected to the heating roller 107. The cam 204 is in pressing fit with the adjacent pushing block 205, and the concave surface of the cam 204 is close to the side of the ink printing plate 110.

[0040] When the ink printing plate 110 rotates, in order to prevent the roller shaft 105 from slipping, resulting in the ink printing plate 110 being unable to drive the roller shaft 105 to rotate continuously, causing uneven ink output of the ink material. Therefore, the heating roller 107 drives the first gear 201 to rotate, thereby driving the second gear 202 to rotate, and then driving the roller shaft 105 to rotate. In this way, the effect of assisting the rotation of the roller shaft 105 is achieved, enabling the roller shaft 105 to output ink evenly and preventing the situation where the roller shaft 105 cannot rotate and output ink due to slipping; Moreover, through the transmission ratio of the first gear 201 to the second gear 202, the rotation speed of the roller shaft 105 is 1.5 times that of the heating roller 107. Thus, in the same time, more ink material is evenly applied to the ink printing plate 110, avoiding insufficiently applied ink material, resulting in light hot stamping of the leather; In addition, when the ink printing plate 110 contacts the roller shaft 105, the concave surface of the cam 204 corresponds to the pushing block 205, and the telescopic rod 203 extends downward. When the ink printing plate 110 rotates away from the roller shaft 105, the convex surface of the cam 204 presses the pushing block 205 to move upward, thereby driving the first slider 106 thereon to move upward, and the telescopic rod 203 shortens upward, causing the roller shaft 105 to move upward, avoiding the roller shaft 105 from contacting the heating roller 107. In this way, through the cooperation of the pushing block 205 and the cam 204, the present invention enables the roller shaft 105 to discharge ink downward only when the ink printing plate 110 rotates to the top, and no ink is discharged at other times, avoiding ink contamination of the heating roller 107.

[0041] Embodiment 2: On the basis of Embodiment 1, asFigures 8 - 9 As shown, it further includes a first spring 301. The first spring 301 is fixedly connected to the adjacent connecting frame 1031. The telescopic rod of the cylinder 102 is slidably connected to a pressing frame 302 in the up and down direction. The pressing frame 302 is fixedly connected to the adjacent first spring 301. The pressing frame 302 is slidably connected with second sliders 303 symmetrically distributed before and after the pressing frame 302 through inclined grooves. The frame 101 is slidably connected with third sliders 304 corresponding to the second sliders 303. The third sliders 304 are located directly below the corresponding second sliders 303.

[0042] When the leather is placed on the hot stamping tabletop of the frame 101, the bottom of the leather contacts the third slider 304. Initially, when the telescopic rod of the cylinder 102 drives the connecting frame 1031 to move downward, it also drives the pressing frame 302 to move downward synchronously through the first spring 301. The pressing frame 302 drives the second sliders 303 to move downward synchronously. The second sliders 303 first move downward to contact the top surface of the leather. Then, the telescopic rod of the cylinder 102 drives the pressing frame 302 to continue moving downward through the first spring 301, so that the pressing frame 302 moves downward until its bottom surface contacts the second sliders 303. The second sliders 303 cooperate with the corresponding third sliders 304 at the bottom to clamp the four corners of the leather. During this process, the pressing frame 302 squeezes the third sliders 304 to move outward through the inclined grooves, achieving the effect of pulling the four corners of the leather.

[0043] Then, the telescopic rod of the cylinder 102 continues to shorten downward. At this time, since both the pressing frame 302 and the second sliders 303 cannot continue to descend, the telescopic rod of the cylinder 102 slides downward relative to the pressing frame 302, and the first spring 301 is compressed until the hot stamping plate 108 or the ink plate 110 performs hot stamping or inking operations on the leather.

[0044] After stamping, control the telescopic rod of the cylinder 102 to extend upward. The telescopic rod of the cylinder 102 first drives the connecting frame 1031 to move upward, so that the hot stamping plate 108 or the ink plate 110 first separates from the leather. The first spring 301 gradually returns to its original position. Finally, the telescopic rod of the cylinder 102 drives the pressing frame 302 to move upward through the first spring 301, thereby driving the second sliders 303 to move upward and separate from the leather.

[0045] In summary, in the descending process of the present invention, first, the four second sliders 303 and the adjacent third sliders 304 respectively clamp the four corners of the leather and pull them outward, so that the leather maintains tension, and then hot stamping or inking operations are performed on the leather, which helps to ensure that patterns, characters or ink can be accurately transferred to the printing substrate, reducing the risk of offset and misalignment, thereby improving the clarity and detail performance of hot stamping.

[0046] Embodiment 3: On the basis of Embodiment 2, as Figure 10As shown, it further includes a fixed nozzle 401. The fixed nozzle 401 is fixedly connected to the rear side of the sliding frame 103. The outlet of the fixed nozzle 401 faces downward the heating roller 107. A gas pump 402 is fixedly connected to the upper rear side of the frame 101. The gas pump 402 is communicated with the fixed nozzle 401.

[0047] During the rotation, start the gas pump 402 to make the fixed nozzle 401 blow air towards the heating roller 107 from the rear side to clean the heating roller 107 and the stamping plate 108, preventing the excess ink from contaminating the heating roller 107 and the stamping plate 108.

[0048] As Figure 11 shown, it further includes a lifting frame 501. The lifting frame 501 is slidably connected to the frame 101. The lifting frame 501 protrudes from the stamping table surface of the frame 101. Two second springs 502 are fixedly connected between the lifting frame 501 and the frame 101.

[0049] When the stamping plate 108 presses down on the leather, if the leather is relatively thick, it may cause the non-stamping part to easily sink and deform downward. Therefore, the leather is made to protrude upward through the lifting frame 501. In this way, during stamping, under the buffering action of the second spring 502, even if the stamping pressure is large, only the lifting frame 501 is lowered to be flush with the workbench surface.

[0050] It should be understood that the above description is only for exemplary purposes and does not limit the present invention. Those skilled in the art will understand that the variant forms of the present invention will be included within the scope of the claims herein.
