Description

Technical Field

[0001] The present application relates to the technical field of laser imprinting equipment, and in particular to a laser imprinting transfer device. Background Art

[0002] Laser embossing is a method of imprinting patterns using laser technology. It is usually used to add high-gloss, metallic or colorful patterns to the surface of various materials. When laser embossing a pattern, a roller is used to press the pattern paper onto the drawing.

[0003] The existing announcement number is CN201052688Y, and the name is a laser embossing transfer device, which includes a conveying mechanism, a reeling mechanism, a compounding mechanism, a UV curing mechanism, a cooling mechanism, a peeling mechanism and a reeling mechanism. The compounding mechanism is arranged on the conveying mechanism, and the compounding mechanism is composed of a transfer pressure roller and a transfer roller. The transfer pressure roller is arranged above the transfer roller; the peeling mechanism is composed of a film receiving roller and the above transfer roller. The film receiving roller is arranged on one side of the transfer roller and is located behind the transfer pressure roller; the UV curing mechanism is arranged between the transfer pressure roller and the film receiving roller and is close to the transfer roller; the cooling mechanism is arranged above the above On the print transfer roller, since the print transfer roller and the print transfer pressure roller form a composite structure and form a peeling mechanism with the film collection roller, one roller serves two purposes. The laser embossing transfer device of the present invention not only has a compact structure, but also eliminates a roller, thereby saving costs. At the same time, since the print transfer pressure roller, the UV curing mechanism, and the film collection roller are arranged in sequence around the print transfer roller, and the cooling mechanism is arranged on the print transfer roller, the structure of the laser embossing transfer device becomes very compact, which greatly reduces the volume of the laser embossing transfer device, reduces the floor space occupied by the laser embossing transfer device, and also reduces the production cost of the laser embossing transfer device.

[0004] In response to the above-mentioned related technologies, the inventors discovered that the laser embossing transfer device has a transfer roller, which is responsible for ensuring the pressure when the laser film is transferred to the paper. This pressure usually requires a large pressure to transfer the pattern of the laser film to the paper. However, the existing technology lacks a mechanism to pressurize the transfer roller, resulting in the pressure of the transfer roller being not high enough, thereby affecting the quality of the final embossing. Utility Model Content

[0005] In order to overcome the problem that the pressure of the transfer roller is not high enough due to the existing transfer roller pressurizing mechanism, thereby affecting the quality of the final imprint, the present application provides a laser imprint transfer device.

[0006] The laser imprint transfer device provided in this application adopts the following technical solution:

[0007] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0008] By adopting the above technical solution, during use, the laser paper roll and the transfer film roll are respectively plugged and assembled on the conveying parts on both sides of the top surface of the frame, and then the laser paper and the transfer film are transported horizontally to the reeling rod of the conveying part on the other side for reeling. The laser paper and the transfer film pass horizontally through the pressure component, and the laser paper and the transfer film are squeezed together by two pressure rollers. Then, in order to ensure the effectiveness of the lamination of the laser paper and the transfer film, the pressure column on the sliding hole on the top surface of the slide frame is rotated and moved downward. Under the deformation force of the downward pressure spring, the pressure column pushes the pressure column downward to squeeze the lifting slide bar vertically downward in the slide frame, thereby driving the upper pressure roller to squeeze downward, thereby tightening the effectiveness of the lamination of the laser paper and the transfer film. Therefore, by adjusting the number of pressure columns that squeeze the lifting slide bar downward, the pressing force of the pressure roller to squeeze the laser paper and the transfer film downward can be controlled.

[0009] Optionally, multiple elastic sheets are fixed on the outer wall of the pressure roller, and multiple elastic sheets are fixed horizontally along the outer circumference of the pressure roller. The outer sleeve of the pressure roller is provided with a sleeve, and the sleeve is made of rubber. The inner wall of the sleeve is fixed on the top of the multiple elastic sheets.

[0010] By adopting the above technical solution, the multiple elastic sheets laterally arranged on the outer wall of the middle pressure roller are used to deform the support sleeve to push the sleeve to press the laser paper and the transfer film to fit together.

[0011] Optionally, a guide groove is vertically opened on the inner wall of the sliding hole, and a clamping plate is vertically fixed on the outer wall of the pressure column.

[0012] By adopting the above technical solution, the pressure column rotates in the sliding hole. When the clamping plate on the pressure column coincides with the guide groove on the sliding hole, the pressure column slides down vertically in the sliding hole. On the contrary, when the clamping plate on the pressure column is staggered with the guide groove on the sliding hole, the pressure column is vertically clamped in the sliding hole, thereby facilitating the vertical adjustment of the pressure column to slide vertically on the sliding frame, thereby improving the adjustability of the pressure column.

[0013] Optionally, a reeling rod is connected to the lifting slider for horizontal rotation, and a reeling motor is fixed horizontally to the end of the lifting slider, and the output end of the reeling motor is fixed to the end of the reeling rod.

[0014] By adopting the above technical solution, when unwinding the laser paper roll and the transfer film roll in use, the unwinding motor is started to drive the unwinding rod on the lifting slider to rotate, so that the unrolled laser paper and the transfer film are overlapped.

[0015] Optionally, a stud is horizontally fixed to the end of the unwinding rod, and a screw cap is threadedly assembled on the stud.

[0016] By adopting the above technical solution, a stud is horizontally fixed at one end of the unwinding rod during use, and the screw cover assembled on the stud is used to press the laser paper roll and transfer film roll on the rewinding rod to keep the laser paper roll and transfer film roll stable on the unwinding rod.

[0017] Optionally, one side of the lifting slider is horizontally rotatably connected to a winding rod, and a winding motor is horizontally fixed to one side of the lifting slider, and the output end of the winding motor is fixed to the end of the winding rod.

[0018] By adopting the above technical solution, when the laser paper roll and the transfer film roll are being wound up, the winding motor is started to drive the winding rod on the lifting slider to rotate, so as to wind up the laser paper and the transfer film separately.

[0019] Optionally, an adjusting screw is assembled through a vertical thread on the top surface of the lifting frame, and the bottom end of the adjusting screw is rotatably connected to the lifting slider.

[0020] By adopting the above technical solution, the adjusting screw on the top surface of the lifting frame is rotated during use to push the lifting slider to slide vertically on the lifting frame, thereby facilitating vertical adjustment of the unwinding height.

[0021] Optionally, a lamp box is horizontally fixed on a lifting slide block of a conveying member on one side of the frame, and a UV lamp stick is horizontally fixed inside the lamp box.

[0022] By adopting the above technical solution, the UV lamp rod in the lamp box is used to heat the laser paper to increase its temperature, thereby improving the heating effectiveness of the laser paper.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: during use, the laser paper roll and the transfer film roll are respectively plugged and assembled on the conveying parts on both sides of the top surface of the frame, and then the laser paper and the transfer film are transported horizontally to the winding rod of the conveying part on the other side for winding, and the laser paper and the transfer film pass horizontally through the pressure component, and the laser paper and the transfer film are squeezed together by two pressure rollers. Then, in order to ensure the effectiveness of the bonding of the laser paper and the transfer film, the pressure column on the sliding hole on the top surface of the slide frame is rotated and moved downward. Under the deformation force of the downward pressure spring, the pressure column pushes the pressure column downward to squeeze the lifting slide bar vertically downward in the slide frame, thereby driving the upper pressure roller to squeeze downward, thereby compressing the effectiveness of the bonding of the laser paper and the transfer film, and thus by adjusting the number of pressure columns that squeeze the lifting slide bar downward, the pressing force of the pressure roller to squeeze the laser paper and the transfer film downward can be controlled.

[0029] The present application is further described in detail below with reference to the accompanying drawings.

[0030] The embodiment of the present application discloses a laser imprint transfer device. Figure 1 、 Figure 2 、 Figure 3 and Figure 4A laser imprint transfer device includes a frame 1, a pressure member 2 and a conveying member 3. Two conveying members 3 are symmetrically and vertically arranged on both sides of the top surface of the frame 1, and a conveying member 3 is arranged in the middle of the top surface of the frame 1. The conveying member 3 includes a lifting frame 31, which is vertically fixed on the top surface of the frame 1, and a lifting slider 32 is vertically slidably assembled in the lifting frame 31. The lifting slider 32 is horizontally connected to the unwinding rod 33, and the other side of the lifting slider 32 is horizontally connected to the winding rod 34. The pressure member 2 includes a slide frame 21, and the slide frame 21 It is vertically fixed on the top surface of the frame 1, and a rotating bar 22 is horizontally fixed on the inner lower side of the sliding frame 21, and a lifting slide bar 23 is vertically slidably assembled on the inner upper side of the sliding frame 21. The top surfaces of the lifting slide bar 23 and the rotating bar 22 are horizontally rotatably connected with a pressure roller 24. A plurality of sliding holes 25 are opened horizontally and vertically through the top surface of the sliding frame 21, and a pressure column 26 is vertically inserted into each of the plurality of sliding holes 25. A downward pressure spring 27 is vertically sleeved on the outside of the pressure column 26, and the two ends of the downward pressure spring 27 are respectively fixed to the inner top surface of the sliding frame 21 and the bottom of the pressure column 26.

[0031] By adopting the above technical solution, during use, the laser paper roll and the transfer film roll are respectively plugged and assembled on the conveying parts 3 on both sides of the top surface of the frame 1, and then the laser paper and the transfer film are transported horizontally toward the reeling rod 34 of the conveying part 3 on the other side for reeling. The laser paper and the transfer film pass horizontally through the pressure component 2, and the laser paper and the transfer film are squeezed together by two pressure rollers 24. Then, in order to ensure the effectiveness of the lamination of the laser paper and the transfer film, the pressure column 26 on the sliding hole 25 on the top surface of the slide frame 21 is rotated and moved downward. Under the deformation force of the downward pressure spring 27, the pressure column 26 pushes the pressure column 26 to squeeze the lifting slide bar 23 downward vertically in the slide frame 21, thereby driving the upper pressure roller 24 to squeeze downward, thereby tightening the effectiveness of the lamination of the laser paper and the transfer film. Therefore, by adjusting the number of pressure columns 26 that squeeze the lifting slide bar 23 downward, the pressing force of the pressure roller 24 squeezing the laser paper and the transfer film downward can be controlled.

[0032] Reference Figure 3 The outer wall of the pressure roller 24 is fixed with multiple elastic sheets 241, and multiple elastic sheets 241 are fixed transversely along the outer circumference of the pressure roller 24. The outer surface of the pressure roller 24 is covered with a sleeve 242 made of rubber. The inner wall of the sleeve 242 is fixed to the top of the multiple elastic sheets 241. The multiple elastic sheets 241 arranged transversely on the outer wall of the pressure roller 24 are used to deform and support the sleeve 242, pushing the sleeve 242 against the laser paper and transfer film to form a bond.

[0033] Reference Figure 3A guide groove is vertically formed on the inner wall of the sliding hole 25, and a clamping plate 261 is vertically fixed to the outer wall of the pressure column 26. The pressure column 26 rotates in the sliding hole 25. When the clamping plate 261 on the pressure column 26 coincides with the guide groove on the sliding hole 25, the pressure column 26 slides vertically in the sliding hole 25. Conversely, when the clamping plate 261 on the pressure column 26 and the guide groove on the sliding hole 25 are misaligned, the pressure column 26 is vertically clamped in the sliding hole 25, thereby facilitating vertical adjustment of the pressure column 26 sliding vertically down on the sliding frame 21 and improving the adjustability of the pressure column 26.

[0034] Reference Figure 4 The lifting slider 32 is horizontally connected to a reeling rod 33, and a reeling motor 36 is horizontally fixed to the end of the lifting slider 32. The output end of the reeling motor 36 is fixed to the end of the reeling rod 33. When unwinding the laser paper roll and transfer film roll during use, the reeling motor 36 is started to rotate the reeling rod 33 on the lifting slider 32, so that the laser paper and transfer film can be unwound and overlapped. A stud 331 is horizontally fixed to the end of the reeling rod 33, and a screw cap 332 is threadedly assembled on the stud 331. During use, a stud 331 is horizontally fixed to one end of the reeling rod 33, and the screw cap 332 assembled on the stud 331 is used to press the laser paper roll and transfer film roll onto the reeling rod 33, keeping the laser paper roll and transfer film roll stable on the reeling rod. One side of the lift slider 32 is connected to a reel rod 34 for horizontal rotation. A reel motor 37 is also fixed horizontally to one side of the lift slider 32, with the output end of the reel motor 37 fixed to the end of the reel rod 34. When reeling in laser paper and transfer film rolls, the reel motor 37 is activated to rotate the reel rod 34 on the lift slider 32, thereby reeling in the laser paper and transfer film, respectively.

[0035] Reference Figure 4 The vertical thread on the top surface of the lifting frame 31 is assembled with an adjusting screw 35, and the bottom end of the adjusting screw 35 is rotatably connected to the lifting slider 32. During use, the adjusting screw 35 on the top surface of the lifting frame 31 is rotated to push the lifting slider 32 to slide vertically on the lifting frame 31, so as to facilitate vertical adjustment of the unwinding height.

[0036] Reference Figure 4 A lamp box 38 is fixed horizontally on the lifting slider 32 of the conveying member 3 on one side of the frame 1, and a UV lamp rod 39 is fixed horizontally inside the lamp box 38. The UV lamp rod 39 in the lamp box 38 is used to heat the laser paper and increase the heating efficiency of the laser paper.

[0037] The implementation principle of a laser embossing transfer device in an embodiment of the present application is as follows: during use, the laser paper roll and the transfer film roll are respectively plugged and assembled on the conveying parts 3 on both sides of the top surface of the frame 1, and then the laser paper and the transfer film are transported horizontally toward the winding rod 34 of the conveying part 3 on the other side for winding. The laser paper and the transfer film pass horizontally through the pressure component 2, and the laser paper and the transfer film are squeezed together by two pressure rollers 24. Then, in order to ensure the effectiveness of the bonding between the laser paper and the transfer film, the pressure column 26 on the sliding hole 25 on the top surface of the slide frame 21 is rotated to move downward. Under the deformation force of the downward pressure spring 27, the pressure column 26 pushes the pressure column 26 downward to squeeze the lifting slide bar 23 and move vertically downward in the slide frame 21, thereby driving the upper pressure roller 24 to squeeze downward, thereby pressing the effectiveness of the bonding between the laser paper and the transfer film.

[0038] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
