Description
Technical Field
[0001] This invention relates to the field of hot-press lamination printing equipment technology, specifically to a hot-press lamination printing equipment and its usage method. Background Technology
[0002] In the field of hot-press lamination printing, the cooling process after hot pressing is crucial to ensuring the quality of the composite material. Currently, most hot-press lamination equipment on the market uses cooling rollers with built-in cooling water circulation systems for cooling, but this approach faces numerous technical bottlenecks in practical applications.
[0003] In traditional equipment, cooling water often remains inside the cooling rollers after the cooling process is complete. Over time, this can lead to scale buildup inside the rollers, resulting in reduced cooling efficiency and uneven temperature distribution. Uneven cooling can cause differential shrinkage in localized areas of the composite material, leading to quality problems such as warping and twisting, which severely impacts product yield. Summary of the Invention
[0004] The purpose of this invention is to provide a hot-press composite printing device and its method of use to solve the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:
[0006] This invention relates to a hot-press lamination printing device, comprising a mounting frame, and further comprising:
[0007] A tilting mechanism is provided, which is mounted on a mounting frame. The tilting mechanism includes several mounting rods fixedly mounted on the front of the mounting frame. Cooling hollow roller one and cooling hollow roller two are provided inside the mounting frame. Limiting arc-shaped boxes are fixedly mounted on the mounting rods. Arc-shaped rods are fixedly mounted inside the limiting arc-shaped boxes. Limiting springs are fixedly mounted on the top inner walls of the limiting arc-shaped boxes. The bottom ends of the limiting springs are fixedly connected to cooling hollow roller one and cooling hollow roller two. The tilting mechanism is used to drain water from cooling hollow roller one and cooling hollow roller two when the device stops operating.
[0008] A pre-pressing mechanism is mounted on a mounting frame. The pre-pressing mechanism includes two rectangular slots formed on the mounting frame. A round rod is fixedly installed in each of the two rectangular slots. A clamping spring and a rectangular slider are respectively sleeved on the two round rods. The top ends of the two clamping springs are fixedly connected to the two rectangular sliders. A pre-pressing roller is rotatably mounted on the two rectangular sliders. The pre-pressing mechanism is used to remove air between the substrate and the printing material.
[0009] Furthermore, the tilting mechanism also includes two mounting blocks fixedly installed on the back of the mounting frame. The first and second hollow cooling rollers are respectively hinged to the two mounting blocks. An L-shaped limiting plate is slidably installed inside the mounting frame, and a rotating wheel is rotatably installed on the top of the L-shaped limiting plate.
[0010] Furthermore, a temperature-controlled pump is fixedly installed on the back of the mounting frame, and a connecting pipe is fixedly installed on the back of the temperature-controlled pump. The connecting pipe communicates with the cooling hollow roller. A water outlet pipe is fixedly installed on the front of the cooling hollow roller. A rectangular transmission box is fixedly installed on the front of the mounting frame. The end of the water outlet pipe communicates with the rectangular transmission box. A water inlet pipe is fixedly installed on the back of the rectangular transmission box. The end of the water inlet pipe communicates with the temperature-controlled pump.
[0011] Furthermore, a compression spring is fixedly installed on the top inner wall of the rectangular transmission box, and a rectangular plate is fixedly installed on the bottom end of the compression spring. The rectangular plate slides inside the rectangular transmission box, and an L-shaped connecting rod is fixedly installed on the bottom end of the rectangular plate. The bottom end of the L-shaped connecting rod slides out of the rectangular transmission box. A transmission plate is fixedly installed on the front side of the L-shaped connecting rod, and two L-shaped round rods are fixedly installed on the back side of the transmission plate. The bottom ends of the two L-shaped round rods are respectively in contact with cooling hollow roller one and cooling hollow roller two.
[0012] Furthermore, the pre-compression mechanism also includes several pre-compression rollers fixedly installed in the mounting frame, a C-shaped plate fixedly installed on the pre-compression rollers, a connecting plate hinged to the C-shaped plate, and an I-beam plate fixedly installed in the mounting frame.
[0013] Furthermore, a connecting block and a movable plate are slidably sleeved on the I-beam plate, a return spring is fixedly installed between the connecting block and the movable plate, the bottom end of the connecting plate is hinged to the connecting block, and the movable plate is hinged to the L-shaped limiting plate.
[0014] Furthermore, several flattening rollers are rotatably mounted on the mounting frame, and a printing material roller and a substrate roller are rotatably mounted inside the mounting frame. The printing material on the printing material roller passes through the several flattening rollers.
[0015] Furthermore, a hot-pressing roller and a pressure-bearing roller are rotatably mounted inside the mounting frame, and the hot-pressing roller and the pressure-bearing roller are parallel to the pre-pressing roller one and the pre-pressing roller two. A collecting roller is rotatably mounted on the mounting frame.
[0016] Furthermore, a second temperature-controlled pump is fixedly installed on the back of the mounting bracket, and a second connecting pipe is fixedly installed on the second temperature-controlled pump. The second connecting pipe is connected to the second cooling hollow roller. A second water outlet pipe is fixedly installed on the front of the second cooling hollow roller. The end of the second water outlet pipe is connected to the second temperature-controlled pump. The second connecting pipe, the second water outlet pipe, the first connecting pipe, the first water outlet pipe, and the inlet pipe are all made of corrugated pipe material.
[0017] Furthermore, the hot-press lamination printing equipment comprises the following steps:
[0018] S1: Flexible Cooling: After the cooling operation is completed, temperature control pump one and temperature control pump two are stopped. The water pressure in the corresponding rectangular transmission box decreases. Under the elastic force of the compression spring, the L-shaped connecting rod rises. Under the elastic force of the limit spring, cooling hollow roller one and cooling hollow roller two rise. At this time, the water in cooling hollow roller one and cooling hollow roller two will leave cooling hollow roller one and cooling hollow roller two, avoiding water stagnation in pre-compression roller one and cooling hollow roller two and scaling. This would cause uneven cooling of the composite material by cooling hollow roller one or cooling hollow roller two in the next cooling, resulting in local warping or twisting and affecting the quality of the composite material.
[0019] S2: Pre-pressure venting: When the first cooling hollow roller descends to the cooling position, it contacts the rotating wheel on the L-shaped limit plate. The rotating wheel drives the L-shaped limit plate to descend, which in turn drives the movable plate to move towards the first pre-pressure roller. The movable plate drives the return spring to move, which in turn drives the connecting block to move. The connecting block drives the connecting plate to move, which in turn drives the C-shaped plate to rise. The C-shaped plate then drives the second pre-pressure roller to rise. The second pre-pressure roller works with the first pre-pressure roller to vent air from the printed material and substrate, preventing air bubbles from forming in the composite material and affecting its quality. The return spring absorbs the thrust of the movable plate on the connecting block, making the compression between the second and first pre-pressure rollers elastic and preventing excessive deformation of the composite material.
[0020] S3: Gradient Cooling: When the printed material passes through the flattening roller, it will be flattened under the action of the flattening roller to avoid the material wrinkles that would cause insufficient local pressure during lamination. After the printed material and the substrate pass through the hot press roller and the bearing roller, they will form a composite material. The composite material will pass through the first cooling hollow roller, which has a temperature of 25°C, and then through the second cooling hollow roller, which has a temperature of 15°C. This gradient cooling of the newly hot-pressed composite material ensures that the composite material will not have increased molecular chain crystallinity due to excessive cooling, but will not be disordered, which would lead to increased brittleness, decreased toughness, and weakened bending resistance.
[0021] The present invention has the following beneficial effects:
[0022] This invention discloses a hot-press lamination printing device. When lamination is required, temperature control pump one and temperature control pump two are simultaneously activated. Temperature control pump two pumps 15°C water through connecting pipe two into cooling hollow roller two, filling the entire cooling hollow roller two. The 15°C water then returns from outlet pipe two to temperature control pump two, forming a circulating cooling process. Correspondingly, temperature control pump one pumps 25°C water through connecting pipe one to cool hollow roller one. The 25°C water then enters a rectangular transmission box through outlet pipe one. Under water pressure, the water pushes a rectangular plate downwards. The rectangular plate drives an L-shaped connecting rod downwards, which in turn drives a transmission plate downwards. The transmission plate drives an L-shaped round rod downwards, pushing cooling hollow roller one and cooling hollow roller two to a parallel state. Correspondingly, cooling hollow roller one and cooling hollow roller two will then drive a limit... The spring is stretched, ultimately positioning the first and second hollow cooling rollers in a suitable cooling posture. Water at 25°C then enters the temperature-controlled pump from the inlet pipe to complete the circulation process. After cooling is complete, the temperature-controlled pumps stop running, causing the water pressure in the rectangular transmission box to decrease. Under the force of the compression spring, the L-shaped connecting rod rises, and under the force of the limit spring, the first and second hollow cooling rollers rise. At this point, the water in the first and second hollow cooling rollers leaves, preventing water from stagnating in the pre-compression rollers and causing scaling. This would prevent uneven cooling of the composite material during the next cooling cycle, leading to localized warping or twisting and affecting the quality of the composite material.
[0023] (2) In the hot-press composite printing equipment of the present invention, when the cooling hollow roller 1 descends to the cooling position, the cooling hollow roller 1 will contact the rotating wheel on the L-shaped limiting plate during descent. The rotating wheel will drive the L-shaped limiting plate to descend. The L-shaped limiting plate will drive the movable plate to move in the direction of the pre-press roller 1. The movable plate will drive the reset spring to move. The reset spring will drive the connecting block to move. The connecting block will drive the connecting plate to move. The connecting plate will drive the C-shaped plate to rise. The C-shaped plate will drive the pre-press roller 2 to rise. The pre-press roller 2 will cooperate with the pre-press roller 1 to squeeze and vent the printed material and substrate that have passed through, so as to avoid air between the printed material and the substrate, which will cause air bubbles in the composite material after molding and affect the quality of the composite material. The corresponding reset spring will absorb the thrust of the movable plate on the connecting block, so that the compression of the pre-press roller 2 and the pre-press roller 1 is elastic compression, and the composite material will not be subjected to excessive stress and deformation.
[0024] (3) The present invention provides a hot-pressing composite printing equipment. When in use, the collecting roller is started, and the collecting roller drives the composite material to move. Since the composite material is formed by hot pressing the printing material and the substrate, the corresponding printing material and substrate drive the printing material roller and the substrate roller to rotate respectively. When the printing material passes through the flattening roller, it will be flattened under the action of the flattening roller to avoid the material wrinkles causing insufficient local pressure during the composite process. After the printing material and the substrate pass through the hot pressing roller and the bearing roller, a composite material will be formed. The composite material will pass through the first cooling hollow roller, the temperature of which is 25°C, and then through the second cooling hollow roller, the temperature of which is 15°C. The composite material that has just been hot-pressed will be cooled in a gradient to ensure that the composite material will not be cooled too quickly, resulting in increased molecular chain crystallinity but disordered arrangement, which would lead to increased brittleness, decreased toughness, and weakened bending resistance. Finally, the composite material that has been cooled in a gradient is wound onto the collecting roller to complete the hot-pressing composite work.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0039] Please see Figure 1 - Figure 9 As shown, the present invention is a hot-press lamination printing device, including a mounting frame 1, and further comprising:
[0040] A tilting mechanism is mounted on a mounting frame 1. The tilting mechanism includes several mounting rods 103 fixedly mounted on the front of the mounting frame 1. Cooling hollow roller one 102 and cooling hollow roller two 1021 are installed inside the mounting frame 1. Limiting arc-shaped boxes 104 are fixedly mounted on each of the mounting rods 103. Arc-shaped rods 105 are fixedly mounted inside each of the limiting arc-shaped boxes 104. Limiting springs 106 are fixedly mounted on the inner top walls of each of the limiting arc-shaped boxes 104. The bottom ends of the limiting springs 106 are respectively connected to the cooling hollow rollers... Roller 102 and cooling hollow roller 2 1021 are fixedly connected. The tilting mechanism is used to drain water from the cooling hollow roller 102 and cooling hollow roller 2 1021 when the device stops operating. The tilting mechanism also includes two mounting blocks 101 fixedly installed on the back of the mounting frame 1. Cooling hollow roller 102 and cooling hollow roller 2 1021 are respectively hinged to the two mounting blocks 101. An L-shaped limiting plate 107 is slidably installed in the mounting frame 1. A rotating wheel is rotatably installed on the top of the L-shaped limiting plate 107. A temperature control pump is fixedly installed on the back of the mounting frame 1. A connecting pipe 109 is fixedly installed on the back of the temperature control pump 108, and the connecting pipe 109 communicates with the cooling hollow roller 102. A water outlet pipe 110 is fixedly installed on the front of the cooling hollow roller 102. A rectangular transmission box 111 is fixedly installed on the front of the mounting bracket 1. The end of the water outlet pipe 110 communicates with the rectangular transmission box 111. A water inlet pipe 112 is fixedly installed on the back of the rectangular transmission box 111, and the end of the water inlet pipe 112 communicates with the temperature control pump 108. A pressure device is fixedly installed on the top inner wall of the rectangular transmission box 111. A compression spring 113 has a rectangular plate 114 fixedly installed at its bottom end. The rectangular plate 114 slides inside the rectangular transmission box 111. An L-shaped connecting rod 115 is fixedly installed at the bottom end of the rectangular plate 114. The bottom end of the L-shaped connecting rod 115 slides to the outside of the rectangular transmission box 111. A transmission plate 116 is fixedly installed on the front side of the L-shaped connecting rod 115. Two L-shaped round rods 117 are fixedly installed on the back side of the transmission plate 116. The bottom ends of the two L-shaped round rods 117 are in contact with the first cooling hollow roller 102 and the second cooling hollow roller 1021, respectively.
[0041] Temperature control pump 108 fills the cooling hollow roller 102 with 25°C water through connecting pipe 109. The 25°C water then enters the rectangular transmission box 111 through outlet pipe 110. Under water pressure, the water pushes the rectangular plate 114 downwards. The rectangular plate 114 drives the L-shaped connecting rod 115 downwards, which in turn drives the transmission plate 116 downwards. The transmission plate 116 then drives the L-shaped round rod 117 downwards, pushing the cooling hollow roller 102 and the cooling hollow roller 2021 to a parallel position. Correspondingly, the cooling hollow roller 102 and the cooling hollow roller 2021 will stretch the limit spring 106, ultimately aligning them in a suitable cooling posture. The corresponding 25°C water then enters the temperature control pump through inlet pipe 112. The cycle is completed within 108. After the cooling process is finished, the temperature control pump 108 and temperature control pump 207 are stopped. The water pressure in the corresponding rectangular transmission box 111 decreases. Under the elastic force of the compression spring 113, the L-shaped connecting rod 115 rises. Under the elastic force of the limit spring 106, the cooling hollow roller 102 and cooling hollow roller 2021 rise. At this time, the water in the cooling hollow roller 102 and cooling hollow roller 2021 will leave the cooling hollow roller 102 and cooling hollow roller 2021 to avoid water stagnation in the pre-compression roller 102 and cooling hollow roller 2021, which would cause scaling. This would make the cooling hollow roller 102 or cooling hollow roller 2021 uneven when cooling the composite material next time, resulting in local warping or twisting and affecting the quality of the composite material.
[0042] like Figure 6 and Figure 7 As shown, a pre-pressing mechanism is mounted on a mounting frame 1. The pre-pressing mechanism includes two rectangular slots 201 formed on the mounting frame 1. Round rods 202 are fixedly installed in each of the two rectangular slots 201. Clamping springs 203 and rectangular sliders 204 are respectively sleeved on the two round rods 202. The top ends of the two clamping springs 203 are fixedly connected to the two rectangular sliders 204. Pre-pressing rollers 205 are rotatably mounted on the two rectangular sliders 204. The pre-pressing mechanism is used to remove air between the substrate and the printing material. It also includes several pre-pressure rollers 2 fixedly installed in the mounting frame 1. A C-shaped plate 206 is fixedly installed on the pre-pressure roller 205. A connecting plate 207 is hingedly installed on the C-shaped plate 206. An I-beam plate 208 is fixedly installed in the mounting frame 1. A connecting block 209 and a movable plate 210 are slidably sleeved on the I-beam plate 208. A return spring 211 is fixedly installed between the connecting block 209 and the movable plate 210. The bottom end of the connecting plate 207 is hinged to the connecting block 209. The movable plate 210 is hinged to the L-shaped limiting plate 107.
[0043] L-shaped limiting plate 107 drives movable plate 210 to move towards the direction of pre-pressure roller 2. Movable plate 210 drives return spring 211 to move, return spring 211 drives connecting block 209 to move, connecting block 209 drives connecting plate 207 to move, connecting plate 207 drives chamfered plate 206 to rise, chamfered plate 206 drives pre-pressure roller 205 to rise, pre-pressure roller 205 will cooperate with pre-pressure roller 2 to squeeze and vent the printed material and substrate, avoiding air between the printed material and substrate that will cause air bubbles in the composite material after molding, affecting the quality of the composite material. Correspondingly, return spring 211 will absorb the pushing force of movable plate 210 on connecting block 209, so that the squeezing of pre-pressure roller 205 and pre-pressure roller 2 is elastic squeezing, and the composite material will not be excessively deformed by force.
[0044] like Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 8 As shown, several flattening rollers 3 are rotatably mounted on the mounting frame 1. A printing material roller 301 and a substrate roller 302 are rotatably mounted inside the mounting frame 1. The printing material on the printing material roller 301 passes through the flattening rollers 3. A hot press roller 303 and a pressure roller 304 are rotatably mounted inside the mounting frame 1. The hot press roller 303 and the pressure roller 304 are parallel to the pre-press roller 2 and the pre-press roller 205. A collecting roller 305 is rotatably mounted on the mounting frame 1. The back of the mounting frame 1... A temperature control pump 2 307 is fixedly installed on the surface. A connecting pipe 2 308 is fixedly installed on the temperature control pump 2 307. The connecting pipe 2 308 is connected to the cooling hollow roller 2 1021. A water outlet pipe 2 309 is fixedly installed on the front side of the cooling hollow roller 2 1021. The end of the water outlet pipe 2 309 is connected to the temperature control pump 2 307. The connecting pipe 2 308, the water outlet pipe 2 309, the connecting pipe 1 109, the water outlet pipe 1 110, and the water inlet pipe 112 are all made of corrugated pipe material.
[0045] When in use, the collecting roller 305 is activated, which drives the composite material to move. Since the composite material is formed by hot pressing of the printing material and the substrate, the corresponding printing material and substrate drive the printing material roller 301 and the substrate roller 302 to rotate respectively. When the printing material passes through the flattening roller 3, it will be flattened under the action of the flattening roller 3 to avoid the material wrinkles that would cause insufficient local pressure during the lamination. After the printing material and the substrate pass through the hot pressing roller 303 and the bearing roller 304, a composite material is formed. The composite material passes through the cooling hollow roller 102, which has a temperature of 25°C, and then through the cooling hollow roller 21021, which has a temperature of 15°C. This gradient cooling of the newly hot-pressed composite material ensures that the composite material will not have increased molecular chain crystallinity due to excessive cooling, but will not be disordered, resulting in increased brittleness, decreased toughness, and weakened bending resistance. Finally, the gradient-cooled composite material is wound onto the collecting roller 305, completing the hot pressing lamination process.
[0046] like Figure 1-9 As shown, a hot-press lamination printing device has the following steps:
[0047] S1: Flexible Cooling: After the cooling process is completed, the temperature control pump 108 and temperature control pump 207 are stopped. The water pressure in the corresponding rectangular transmission box 111 decreases. Under the elastic force of the compression spring 113, the L-shaped connecting rod 115 rises. Under the elastic force of the limit spring 106, the cooling hollow roller 102 and cooling hollow roller 2021 rise. At this time, the water in the cooling hollow roller 102 and cooling hollow roller 2021 will leave the cooling hollow roller 102 and cooling hollow roller 2021, preventing water from stagnating in the pre-compression roller 102 and cooling hollow roller 2021 and causing scaling. This would prevent uneven cooling of the composite material during the next cooling of the composite material, resulting in local warping or twisting and affecting the quality of the composite material.
[0048] S2: Pre-compression exhaust: When the cooling hollow roller 102 descends to the cooling position, it will contact the rotating wheel on the L-shaped limit plate 107. The rotating wheel will drive the L-shaped limit plate 107 to descend. The L-shaped limit plate 107 will drive the movable plate 210 to move in the direction of the pre-compression roller 2. The movable plate 210 will drive the return spring 211 to move. The return spring 211 will drive the connecting block 209 to move. The connecting block 209 will drive the connecting plate 207 to move. The connecting plate 207 will... The convex plate 206 is driven to rise, which in turn drives the pre-pressure roller 205 to rise. The pre-pressure roller 205 works with the pre-pressure roller 2 to squeeze and vent the printed material and substrate, preventing air bubbles from forming in the composite material and affecting its quality. The corresponding return spring 211 absorbs the thrust of the movable plate 210 on the connecting block 209, making the compression of the pre-pressure roller 205 and the pre-pressure roller 2 elastic, preventing the composite material from being excessively deformed.
[0049] S3: Gradient Cooling: When the printed material passes through the flattening roller 3, it will be flattened under the action of the flattening roller 3 to avoid the material wrinkles that would cause insufficient local pressure during lamination. After the printed material and the substrate pass through the hot pressing roller 303 and the bearing roller 304, they will form a composite material. The composite material passes through the cooling hollow roller 102, the temperature of which is 25°C, and then through the cooling hollow roller 21021, the temperature of which is 15°C. This gradient cooling of the newly hot-pressed composite material ensures that the composite material will not have increased molecular chain crystallinity due to excessive cooling, but the arrangement will be disordered, resulting in increased brittleness, decreased toughness, and weakened bending resistance.
