Description

Technical Field

[0001] The invention relates to the technical field of environmentally friendly hot stamping technology, and in particular to an environmentally friendly hot stamping technology. Background Art

[0002] Fabric hot stamping is a technique that transfers metallic patterns, text or decorative elements to fabrics through a heat-pressing process. The process uses a combination of heat, pressure and metal foil to create a metallic effect on the fabric, usually with a gold, silver or other lustrous effect. Hot stamping is widely used in the decoration of textiles, such as clothing, household items and advertising fabrics. Hot stamping technology was originally used in the field of paper printing, and with the advancement of technology, it has been gradually introduced into the textile industry. Hot stamping relies on heat transfer machines or manual equipment that can heat and stamp metal foil onto the surface of fabrics. Metal foil is usually made of materials such as aluminum film and copper film, and is treated with a special coating to make it tightly bonded to the fabric at high temperatures, forming a durable and bright pattern. With the improvement of environmental protection requirements, hot stamping technology is also constantly innovating, and some environmentally friendly hot stamping materials and equipment have been applied, making this technology not only meet the needs of decoration, but also meet the standards of sustainable development.

[0003] In the hot stamping process currently used, the screen printing equipment usually relies on manually holding the screen printing template to perform screen printing on the surface of the fabric that has been fixed in position, and then the fabric is moved to the heat press for hot pressing after completion. However, this screen printing method has certain defects. Since the surface of the fabric is relatively soft, although the position has been fixed, during operation, if the screen printing template is slightly tilted during the lowering process, wrinkles may appear on the surface of the fabric. These wrinkles will have an extrusion effect on the fabric, causing the original screen printing effect to be destroyed when the fabric is unfolded after screen printing. What's more serious is that in the subsequent hot stamping film gluing process, the screen printing effect caused by these wrinkles will cause the pattern to deform. Therefore, the existing manual screen printing method not only affects the screen printing effect of the fabric, but also may reduce the clarity and quality of the hot stamping pattern of the fabric. Summary of the invention

[0004] The invention provides an environmentally friendly hot stamping process, which makes the surface of the fabric flat and will not be deformed, improves the silk-screen printing effect on the surface of the fabric, facilitates workers to transfer the silk-screen printed fabric, and increases the service life of the silk-screen printing components.

[0005] The technical solution of the present invention is as follows: Environmentally friendly hot stamping process, including the following process steps: S100: Pattern design: manufacturing a hot stamping template 11 according to a designed pattern, so that a notch corresponding to the designed pattern is opened in the hot stamping template 11; S200: Cleaning and Installation: After cleaning the surface of the hot stamping template 11 and the inner side of the screen printing stencil 12, install the hot stamping template 11 in the groove on the inner side of the screen printing stencil 12. The upper surface of the hot stamping template 11 is flush with the inner side of the screen printing stencil 12, and then place the screen printing stencil 12 on the workbench 13 waiting for processing; S300: Limiting: Through the limiting module, apply a downward force on the screen printing stencil 12 on the workbench 13 to smooth and tighten the fabric on the lower side of the screen printing stencil 12 until the lower side of the screen printing stencil 12 completely adheres to the upper surface of the fabric; S400: Screen Printing: Pour environmentally friendly glue into the screen printing stencil 12, and evenly apply the environmentally friendly glue on the hot stamping template 11 multiple times through the material sweeping module, so that the environmentally friendly glue is evenly applied on the fabric on the lower side of the screen printing stencil 12 through the notch on the hot stamping template 11; S500: Hot Stamping Film Transfer: Reset the limiting module to separate the screen printing stencil 12 from the screen printed fabric. Place the substrate with the hot stamping film into the hot stamping machine. Through the hot pressing process, the machine heats up and presses the hot stamping film on the surface of the fabric, and part of the hot stamping film will be transferred to the screen printed area on the fabric; S600: Cooling: Wait for the screen printed area to cool to ensure that the transfer effect is fixed, and remove the excess hot stamping film, leaving only the metallic effect of the pattern part; S700: Quality Inspection: Check whether the hot stamping effect is uniform, whether there are defective or incomplete areas, and for defective areas, perform necessary trimming; S800: Finished Product Processing: Package, label or perform other subsequent processing on the hot stamped finished product to ensure that the finished product meets environmental protection standards and is ready to be delivered to customers.

[0006] Further, the limiting module in step S300 includes: A lifting plate, which is connected to the upper side of the workbench by a driving module for driving the height of the lifting plate; Two transmission plates, each transmission plate is connected to the lower side of the lifting plate, and two driving plates are hinged to the lower side of each transmission plate. One end of each driving plate away from the transmission plate is hinged to a clamping plate; Each clamping plate is slidably abutted against the side of the screen printing stencil, and a pressure plate is rotatably connected to each clamping plate. A pressure roller is rotatably connected between two coaxial pressure plates; A reset tension spring is connected between each clamping plate and the screen printing stencil.

[0007] Further, a clamping block is connected between each pressure plate and the side of the screen printing stencil. Two clamping bars are fixedly connected to both side surfaces of the screen printing stencil, and each clamping block is slidably abutted between the two clamping bars.

[0008] Furthermore, a knob is fixedly connected to each of the pressure plates, and two limiting grooves are formed on both side surfaces of the screen printing stencil. Each of the knobs abuts against the inner wall of the adjacent limiting groove.

[0009] Furthermore, two of the clamping strips on the same side are respectively arranged on both sides of the limiting groove. The side of the clamping strip is tangent to the side of the limiting groove close to the reset spring, and the length of the clamping strip is less than the length of the limiting groove.

[0010] Furthermore, a turnover plate is fixedly connected between the lifting plate and each transmission plate, and an arc surface is formed on the upper side of each pressure plate.

[0011] Furthermore, the material sweeping module in step S400 includes: Two material sweeping plates. One end of each material sweeping plate close to the inner side surface of the screen printing stencil is slidably connected to the inner side surface of the screen printing stencil. A reset column is fixedly connected to each material sweeping plate. A reset plate is slidably connected to each reset column. A linkage plate is rotatably connected to the two reset plates; A transmission block is fixedly connected to the linkage plate. A transmission lead screw is threadedly connected to the transmission block. The transmission lead screw is rotatably connected to the screen printing stencil; A material sweeping motor is fixedly connected to the screen printing stencil. The drive shaft of the material sweeping motor is fixedly connected to the transmission lead screw; A reset spring is sleeved on the reset column.

[0012] Furthermore, two sliding grooves are formed on the inner side surface of the screen printing stencil. One end of each material sweeping plate close to the sliding groove is slidably abutted against the sliding groove, and the threaded surface of the transmission lead screw is longer than the length of the sliding groove.

[0013] The beneficial effects of the present invention are: Through the limit module, the lifting plate is moved. When the lifting plate moves downward, it can drive two driving plates to move to both sides through the transmission plate, that is, drive two pressure rollers to act on the fabric below. Under the limiting action of the clamping strip, the pressure plate drives the two pressure rollers to roll from the center to both sides. This rolling action mainly flattens the fabric. When the fabric is subjected to a pulling force, it will also be reset through the rotation of the pressure rollers, making the surface of the fabric flat without deformation, improving the silk printing effect on the fabric surface. Then, when the lifting plate resets upward a small distance, since the pressure rollers are abutted against both sides of the silk printing screen plate, the upward movement of the lifting plate will directly drive the silk printing screen plate to move upward. After the gap between the lifting plate and the fabric gradually expands, the worker can easily transfer the silk-printed fabric. Through the transmission lead screw in the material sweeping module, the linkage plate is driven, and then two material sweeping plates can be controlled to move in the silk printing screen plate. During the movement, a "V"-shaped angle can be formed, and the glue will flow along the inclined surfaces of the two material sweeping plates to evenly coat the glue on the hot stamping template, improving the brushing effect of the material sweeping plates on the hot stamping template. Then, when the two material sweeping plates are moving, the two material sweeping plates can be buffered by the return spring due to the friction between the glue and the bottom surface of the silk printing screen plate, reducing the wear between the material sweeping plates and the bottom surface of the silk printing screen plate, and improving the service life of the contact part between the material sweeping plates and the silk printing screen plate.

Detailed implementation mode

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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 fall within the scope of protection of the present invention. Embodiment

[0018] As Figures 1 to 6 shown, this embodiment proposes an environmentally friendly hot stamping process, including the following process steps: S100: Pattern design: Make a hot stamping template 11 according to the designed pattern, and make a notch corresponding to the designed pattern in the hot stamping template 11; S200: Cleaning and installation: After cleaning the surface of the hot stamping template 11 and the inner side of the silk screen printing plate 12, then install the hot stamping template 11 in the groove on the inner side of the silk screen printing plate 12. The upper surface of the hot stamping template 11 is flush with the inner side of the silk screen printing plate 12, and then place the silk screen printing plate 12 on the workbench 13 for processing; S300: Limiting: Through the limiting module, apply a downward force on the silk screen printing plate 12 on the workbench 13 to smooth and tighten the fabric on the lower side of the silk screen printing plate 12 until the lower side of the silk screen printing plate 12 completely adheres to the upper surface of the fabric; Through the limiting module, the lifting plate 21 is moved. When the lifting plate 21 moves downward, it can drive the two driving plates 23 to move to both sides through the transmission plate 22, that is, drive the two pressure rollers 26 to act on the fabric on the lower side. With the limiting effect of the clamping strip 29, the pressure plate 25 drives the two pressure rollers 26 to roll from the center to both sides. This rolling effect mainly flattens the fabric. When the fabric is subjected to a pulling force, it will also be reset through the rotation of the pressure rollers 26, making the surface of the fabric flat without deformation, improving the silk-screen printing effect on the fabric surface. Then, when the lifting plate 21 resets upward a small distance, since the pressure rollers 26 are abutted against both sides of the silk-screen printing plate 12, the upward movement of the lifting plate 21 will directly drive the silk-screen printing plate 12 to move upward. After the gap between the lifting plate 21 and the fabric gradually expands, the worker can easily transfer the silk-screened fabric; S400: Silk-screen printing: Pour environmental protection glue into the silk-screen printing plate 12, and through the material-sweeping module, the environmental protection glue is evenly applied on the hot stamping template 11 multiple times, so that the environmental protection glue is evenly applied on the fabric under the silk-screen printing plate 12 through the slots on the hot stamping template 11; The transmission lead screw 36 in the material-sweeping module drives the linkage plate 34, and then controls the two material-sweeping plates 31 to move in the silk-screen printing plate 12. During the movement, a "V"-shaped angle can be formed. The glue will flow along the inclined surfaces of the two material-sweeping plates 31 to evenly coat the hot stamping template 11, improving the brushing effect of the material-sweeping plates 31 on the hot stamping template 11. Then, when the two material-sweeping plates 31 are moving, the two material-sweeping plates 31 can be buffered by the return spring 38 due to the friction between the glue and the bottom surface of the silk-screen printing plate 12, reducing the wear between the material-sweeping plates 31 and the bottom surface of the silk-screen printing plate 12, and improving the service life of the contact part between the material-sweeping plates 31 and the silk-screen printing plate 12; S500: Hot stamping film transfer: Reset the limiting module to separate the silk-screen printing plate 12 from the silk-screened fabric, put the substrate with the hot stamping film into the hot stamping machine, and through the hot pressing process, the machine heats up and presses the hot stamping film on the fabric surface, and part of the hot stamping film will be transferred to the silk-screened area on the fabric; S600: Cooling: Wait for the silk-screened area to cool down to ensure that the transfer effect is fixed, and remove the excess hot stamping film, leaving only the metallic effect of the pattern part; S700: Quality inspection: Check whether the hot stamping effect is uniform, whether there are defective or incomplete areas, and for the defective parts, perform necessary trimming; S800: Finished product processing: Package, label or perform other subsequent processing on the hot-stamped finished product to ensure that the finished product meets the environmental protection standards and is ready to be delivered to the customer.

[0019] As Figures 1 to 6 shown, the limiting module in step S300 includes: The lifting plate 21, and the driving module is connected between the upper side of the lifting plate 21 and the workbench 13 for driving the height of the lifting plate 21; Two transmission plates 22, each transmission plate 22 is connected to the lower side of the lifting plate 21, two driving plates 23 are hinged to the lower side of the transmission plate 22, and one end of each driving plate 23 away from the transmission plate 22 is hinged to each clamping plate 24; Each clamping plate 24 is slidably abutted against the side surface of the silk screen plate 12, each clamping plate 24 is rotatably connected to each pressure plate 25, and the pressure roller 26 is rotatably connected between two coaxial pressure plates 25; Each reset tension spring 27 is connected between each clamping plate 24 and the silk screen plate 12; The limiting module drives the lifting plate 21 to lift through the driving module on the lifting plate 21. The driving module is preferably driven by a cylinder. Since this is a standard part and its working principle is well-known, it will not be elaborated here. When the lifting plate 21 moves downward, it can drive the two driving plates 23 to move to both sides through the transmission plate 22, that is, drive the two pressure rollers 26 to act on the lower fabric. Then, because the angle between the pressure plate 25 and the fabric gradually changes, that is, the component forces received by the two pressure plates 25 also change continuously, and the pulling force of the pressure roller 26 on the fabric also changes continuously. As the acting force of the two pressure rollers 26 on the fabric changes, the fabric is opened to both sides, and then the fabric is elastically reset through its own fibers, making the surface of the fabric smoother before silk screen printing and improving the silk screen printing effect.

[0020] As Figures 1 to 2 and Figure 6 shown, the material sweeping module in step S400 includes: Two material sweeping plates 31, one end of each material sweeping plate 31 close to the inner side surface of the silk screen plate 12 is slidably connected to the inner side surface of the silk screen plate 12, each material sweeping plate 31 is fixedly connected to each reset column 32, the reset plate 33 is slidably connected to the reset column 32, and the linkage plate 34 is rotatably connected to the two reset plates 33; The transmission block 35 is fixedly connected to the linkage plate 34, the transmission block 35 is threadedly connected to the transmission lead screw 36, and the transmission lead screw 36 is rotatably connected to the silk screen plate 12; The material sweeping motor 37, the material sweeping motor 37 is fixedly connected to the silk screen plate 12, and the drive shaft of the material sweeping motor 37 is fixedly connected to the transmission lead screw 36; The reset spring 38 is sleeved on the reset column 32; The material sweeping module drives the linkage plate 34 through the transmission lead screw 36, thereby controlling the two material sweeping plates 31 to move in the screen printing stencil 12. During the movement, a "V"-shaped angle can be formed, and the glue will flow along the inclined surfaces of the two material sweeping plates 31 to evenly coat the hot stamping template 11 with the glue, improving the brushing effect of the material sweeping plate 31 on the hot stamping template 11. Then, when the two material sweeping plates 31 are moving, the two material sweeping plates 31 can be buffered by the return spring 38 due to the friction between the glue and the bottom surface of the screen printing stencil 12, reducing the wear between the material sweeping plate 31 and the bottom surface of the screen printing stencil 12, and improving the service life of the contact part between the material sweeping plate 31 and the screen printing stencil 12.

[0021] As Figures 1 to 3 shown, the two sliding grooves 122 are respectively opened on the inner side surface of the screen printing stencil 12, and one end of each material sweeping plate 31 close to the sliding groove 122 is in sliding contact with the sliding groove 122, and the threaded surface of the transmission lead screw 36 is longer than the groove length of the sliding groove 122; The transmission lead screw 36 drives the two material sweeping plates 31 to move to the other side. Then, when moving to the other side, since the threaded surface of the transmission lead screw 36 is longer than the groove length of the sliding groove 122, the angle between the two material sweeping plates 31 and the inner side surface of the screen printing stencil 12 changes, and then the two material sweeping plates 31 are driven to reset, so that the two material sweeping plates 31 move back and forth in a "V" angle structure, enabling the glue to be evenly coated on the hot stamping template 11 along the sides of the two material sweeping plates 31. Furthermore, this part of the glue can pass through the slots on the hot stamping template 11 and be screen-printed on the fabric. Embodiment

[0022] On the basis of Embodiment 1, this embodiment improves the flipping action of the pressure plate 25; As Figures 1 to 6 shown, each clamping block 28 is connected between each pressure plate 25 and the side surface of the screen printing stencil 12, and two clamping bars 29 are fixedly connected to the side surface of the screen printing stencil 12, and each clamping block 28 is in sliding contact between the two clamping bars 29; The clamping strip 29, through the abutting action with the clamping block 28 between the two clamping strips 29, keeps the angle between the pressure plate 25 and the silk screen printing plate 12 unchanged when the lifting plate 21 moves downward, that is, the angle between the pressure plate 25 and the fabric remains unchanged. Therefore, the acting force of the pressure roller 26 on the fabric remains unchanged. The pressure plate 25 drives the two pressure rollers 26 to roll from the center to both sides. This rolling action mainly flattens the fabric. When the fabric is subjected to a pulling force, it will also be reset through the rotation of the pressure roller 26, making the surface of the fabric flat without deformation, improving the silk screen printing effect on the fabric surface. Then, when the lifting plate 21 resets upward a small distance, since the pressure roller 26 abuts on both sides of the silk screen printing plate 12, the upward movement of the lifting plate 21 will directly drive the silk screen printing plate 12 to move upward. After the gap between the lifting plate 21 and the fabric gradually expands, the worker can easily transfer the silk screen printed fabric. After the transfer is completed, by manually intervening in the position of the pressure roller 26, the pressure roller 26 will reset under the pulling force of the reset tension spring 27. The pressure roller 26 gradually flips downward to reset each component, and the pressure roller 26 continues to support the silk screen printing plate 12.

[0023] As Figures 1 to 3 shown, each knob 210 is fixedly connected to each pressure plate 25, and two limiting grooves 121 are formed on the side surface of the silk screen printing plate 12. Each knob 210 abuts against the inner wall of the adjacent limiting groove 121 respectively; When the acting force of the reset tension spring 27 on the pressure roller 26 remains unchanged through the knob 210, manual intervention can be carried out. The knob 210 is rotated manually to make the pressure roller 26 clamped on both side surfaces of the silk screen printing plate 12 flip downward.

[0024] As Figures 2 to 6 shown, two clamping strips 29 on the same side are respectively arranged on both sides of the limiting groove 121. The side of the clamping strip 29 is tangent to the side of the limiting groove 121 close to the reset tension spring 27, and the length of the clamping strip 29 is less than the groove length of the limiting groove 121; The clamping strip 29, through the abutting action with the clamping block 28 between the two clamping strips 29, keeps the height of the silk screen printing plate 12 unchanged when the lifting plate 21 moves downward, driving the two pressure rollers 26 to roll from the center to both sides, so that the fabric on the lower side of the silk screen printing plate 12 remains flat. At the same time, the frictional force between the pressure roller 26 and the fabric can also make the fabric receive a small pulling and traction effect, further ensuring the flatness of the surface of the fabric to be screen-printed, improving the screen printing effect. Because the groove length of the limiting groove 121 is greater than the length of the clamping strip 29, when the pressure roller 26 moves to the outermost side, the pressure roller 26 is no longer limited by the clamping strip 29. At this time, the silk screen printing plate 12 starts to move towards the fabric, and then the pressure rollers 26 on both sides gradually turn up. During the turning-up process, it always has a certain pulling effect on the fabric, keeping the fabric surface flat until the bottom surface of the lower side of the silk screen printing plate 12 completely presses the fabric flat, and then the pressure rollers 26 completely turn up, that is, the pressure rollers 26 do not act on the fabric. The gap between the silk screen printing plate 12 and the tabletop of the workbench 13 allows the fabric fibers under the pulling effect to reset. Because the fabric fibers are elastic, they will reset when not under force, improving the flatness of the fabric and ensuring the screen printing effect of the fabric, so that the printed pattern will not change, ensuring the subsequent hot stamping effect.

[0025] As Figures 1 to 3 shown, the flipping plate 211 is fixedly connected between the lifting plate 21 and each transmission plate 22, and the arc surface 251 is formed on the upper side of each pressure plate 25; When the flipping plate 211 gradually moves downward along with the lifting plate 21, at this time, the two pressure plates 25 on one side gradually slide towards both sides. Then when the clamping block 28 slides out of the area between the upper and lower clamping strips 29, the upper and lower clamping strips 29 no longer limit the clamping block 28. Then, due to the downward action of the inclined surfaces on both sides of the flipping plate 211 on the arc surface 251, the arc surface 251 will tilt along the inclined surface of the flipping plate 211, thereby causing one end of the pressure plate 25 with the pressure roller 26 to turn up, enabling the bottom surface of the silk screen printing plate 12 to completely press the fabric. At this time, the fabric has been smoothed by the pressure roller 26 and the surface is already flat enough, improving the screen printing effect on the fabric surface. At the same time, the abutting action between the inclined surface of the flipping plate 211 and the arc surface 251 limits the flipping action of the pressure plate 25, ensuring that the pressure roller 26 can be completely turned up.

[0026] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
