Description

Technical Field

[0001] This utility model relates to the technical field of thermal paper processing equipment, and in particular to a high-gloss paper coating device. Background Technology

[0002] High-gloss paper is a type of processed paper. Its manufacturing process involves coating a layer of thermal coating onto high-quality base paper. When heated by a thermal printer, this coating develops color, forming various image information such as barcodes, QR codes, graphics, and text. However, the printed thermal images are directly exposed and easily become blurred due to natural oxidation or friction and wear during transportation and movement, severely affecting subsequent information recognition. Lamination is an effective solution to these problems. However, existing high-gloss paper lamination devices still have significant issues: lamination quality is highly dependent on the pressure applied by the pressure rollers to the protective film and high-gloss paper. Insufficient pressure leads to weak lamination, air bubbles, or localized delamination, failing to effectively isolate air and friction; excessive pressure may damage the thermal coating or cause material deformation. Existing devices generally lack a convenient, precise, and stable pressure adjustment mechanism. Therefore, it is necessary to develop a high-gloss paper lamination device that can accurately and conveniently adjust and lock the pressure rollers on the protective film and high-gloss paper to ensure a firm and reliable lamination. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a high-gloss paper coating device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A high-gloss paper laminating device is designed, comprising a base frame, a film roll and a thermal paper roll disposed on one side of the base frame, a take-up roll disposed on the other side of the base frame, a pressure roll for pressing the protective film and the high-gloss paper, a pressure regulating component connected to the pressure roll, a drive shaft connected to the pressure regulating component via a control component, a linkage component connecting the drive shaft and the take-up roll, and a handwheel disposed at one end of the drive shaft. The control component controls the lifting and lowering of the pressure regulating component under the drive of the drive shaft. The control component includes a lifting plate, a support rod disposed on the lifting plate, a swing rod hinged to the top of the support rod, an eccentric wheel connected to the swing rod via a rotating shaft, a connection control part connecting the other end of the eccentric wheel to the drive shaft, and a limiting part for fixing the lifting plate on the base frame.

[0006] Furthermore, the connection control unit includes a through hole penetrating the eccentric wheel, an annular groove formed on the inner wall of the through hole, blocking blocks distributed along the annular groove array, an inner groove provided on the drive shaft, a magnetic block that slides with the inner groove, an electromagnet provided at the bottom of the inner groove, a mounting groove provided on the inner wall of the inner groove, and a first spring connecting the inner wall of the mounting groove and the magnetic block.

[0007] Furthermore, the limiting part includes a fixed plate on the lifting plate, a plug rod slidably connected to the fixed plate, a baffle on the plug rod, a second spring connecting the baffle and the fixed plate, and a slot on the base frame for inserting the plug rod.

[0008] Furthermore, the pressure regulating assembly includes a U-shaped plate connected to both ends of the pressure roller, a third spring connecting the U-shaped plate and the lifting plate, and a guide rod fixed to the bottom of the lifting plate and slidably engaged with the U-shaped plate.

[0009] Furthermore, it also includes guide grooves symmetrically formed on the base frame, a lower pressure block that slides with the guide groove, and a fourth spring connecting the lower pressure block and the bottom of the guide groove.

[0010] Furthermore, the linkage component includes a drive sprocket connected to the drive shaft, a driven sprocket connected to one end of the take-up roller, and a chain connecting the drive sprocket and the driven sprocket.

[0011] Furthermore, the base frame is also provided with a tension balancing assembly, which includes guide rollers connected to the base frame at both ends, a swing arm provided on the guide rollers, protrusions and counterweights respectively provided at both ends of the swing arm, and an arc-shaped groove opened on the base frame and slidingly engaged with the protrusions.

[0012] Furthermore, the base frame is provided with an adhesive spray nozzle below the protective film and a hot air outlet above the protective film.

[0013] The high-gloss paper coating device proposed in this utility model has the following advantages:

[0014] This invention connects the eccentric wheel and the drive shaft via a connecting control unit. A handwheel drives the drive shaft to rotate, causing the eccentric wheel to swing the swing arm and push the support rod to rise and fall. This, in turn, causes the lifting plate to rise and fall with the pressure adjustment component. A limiting part fixes the position of the lifting plate and the adjustment component, thus adjusting the pressure of the pressure roller on the protective film and glossy paper roller. After adjusting the pressure of the pressure roller on the protective film and glossy paper roller, the connecting control unit disconnects the eccentric wheel and the drive shaft. The rotation of the drive shaft continues to drive the winding roller through the linkage component. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example, refer to Figures 1-7 A high-gloss paper coating apparatus includes a base frame 1, a film roll 2 for winding a protective film and a high-gloss paper roll 3 for winding high-gloss paper, both located on one side of the base frame 1, a take-up roll 4 located on the other side of the base frame 1, and a pressure roll 5 for pressing the protective film and the high-gloss paper. In this embodiment, the film roll 2 is located above the high-gloss paper roll 3. The apparatus also includes a pressure regulating component 6 connected to the pressure roll 5, a drive shaft 8 connected to the pressure regulating component 6 via a control component 7, and a linkage component connecting the drive shaft 8 and the take-up roll 4. 9. A handwheel 10 is provided at one end of the drive shaft 8. The control component 7 controls the lifting and lowering of the pressure regulating component 6 under the drive of the drive shaft 8. The control component 7 includes a lifting plate 701, a support rod 702 provided on the lifting plate 701, a swing rod 703 hinged to the top of the support rod 702, an eccentric wheel 705 connected to the swing rod 703 through a rotating shaft 704, a connection control part 706 connecting the other end of the eccentric wheel 705 to the drive shaft 8, and a limiting part 707 for fixing the lifting plate 701 on the base frame 1.

[0024] This invention connects the eccentric wheel 705 and the drive shaft 8 via the connecting control unit 706. The handwheel 10 drives the drive shaft 8 to rotate, causing the eccentric wheel 705 to swing the swing rod 703 and push the support rod 702 up and down. This, in turn, causes the lifting plate 701 to move the pressure regulating component 6 up and down. The position of the lifting plate 701 and the regulating component 6 is fixed by the limiting part 707, thus adjusting the pressure of the pressure roller 5 on the protective film and the glossy paper roller. After adjusting the pressure of the pressure roller 5 on the protective film and the glossy paper roller, the connecting control unit 706 disconnects the eccentric wheel 705 and the drive shaft 8. The drive shaft 8 rotates and continues to drive the take-up roller 4 through the linkage component 9.

[0025] In an optional embodiment of this utility model, the connection control unit 706 includes a through hole 7061 penetrating the eccentric wheel 705, an annular groove 7062 formed on the inner wall of the through hole 7061, blocking blocks 7063 arranged in an array along the annular groove 7062, an inner groove 7064 provided on the drive shaft 8, a magnetic block 7065 slidably engaged with the inner groove 7064, an electromagnet 7066 provided at the bottom of the inner groove 7064, a mounting groove 7067 provided on the inner wall of the inner groove 7064, and a first spring 7068 connecting the inner wall of the mounting groove 7067 and the magnetic block 7065. Preferably, in this embodiment, the drive shaft 8 and the through hole 7061 are rotatably connected, and the drive shaft 8 is located on the eccentric wheel. Limiting plates can be installed on both sides of wheel 705, and buttons can be installed on handwheel 10. Pressing the button controls the electromagnet 7066 to be energized. After the electromagnet 7066 is energized, its magnetism is opposite to that of the magnetic block 7065, which allows the magnetic block 7065 to move towards the inner wall of the annular groove 7062. When the drive shaft 8 rotates, the magnetic block 7065 abuts against the blocking block 7063 and drives the eccentric wheel 705 to rotate. After the pressure roller 5 has adjusted the pressure of the protective film and the thermal paper roller, the electromagnet 7066 is de-energized, and the magnetic block 7065 enters the recessed groove 7064 under the action of the first spring 7068. At this time, after the drive shaft 8 rotates, the magnetic block 7065 and the blocking block 7063 are no longer in contact.

[0026] In an optional embodiment of this utility model, the limiting part 707 includes a fixing plate 7071 disposed on the lifting plate 701, a plug rod 7072 slidably connected to the fixing plate 7071, a baffle 7073 disposed on the plug rod 7072, a second spring 7074 connecting the baffle 7073 and the fixing plate 7071, and a slot 7075 disposed on the base frame 1 for inserting the plug rod 7072. The plug rod 7072 is inserted into the slot 7075 of the base frame 1 by the pushing force of the second spring 7074, fixing the position of the lifting plate 701. When adjustment is required, the plug rod 7072 is manually pulled out and disengaged from the slot 7075.

[0027] In an optional embodiment of this utility model, the pressure regulating component 6 includes a U-shaped plate 601 connected to both ends of the pressure roller 5, a third spring 602 connecting the U-shaped plate 601 and the lifting plate 701, and a guide rod 603 fixed to the bottom of the lifting plate 701 and slidably engaged with the U-shaped plate 601. Preferably, in this embodiment, the third spring 602 is sleeved on the guide rod 603, and the third spring 602 is symmetrically distributed between the lifting plate 701 and the U-shaped plate 601. When the lifting plate 701 descends, the third spring 602 pushes the U-shaped plate 601, the U-shaped plate drives the pressure roller 5 to press down, and the guide rod 603 restricts the offset of the U-shaped plate 601, thereby improving the uniformity of film coating.

[0028] In an optional embodiment of this utility model, it further includes a guide groove 604 symmetrically opened on the base frame 1, a lower pressure block 605 that slides with the guide groove 604, and a fourth spring 606 connecting the lower pressure block 605 and the bottom of the guide groove 604. When the pressure roller 5 presses down, the lower pressure block 605 slides along the guide groove 604. The symmetrically distributed fourth spring 606 and lower pressure block 605 ensure that the pressure roller is subjected to uniform force at both ends.

[0029] In an optional embodiment of this utility model, the linkage component 9 includes a drive sprocket 901 connected to the drive shaft 8, a driven sprocket 902 connected to one end of the take-up roller 4, and a chain 903 connecting the drive sprocket 901 and the driven sprocket 902. When the drive shaft 8 rotates, the drive sprocket 901 drives the driven sprocket 902 through the chain 903, thereby driving the take-up roller 4 to rotate, thus avoiding the problem of uneven winding caused by belt slippage.

[0030] In an optional embodiment of this utility model, the base frame 1 is further provided with a tension balancing component 11. The tension balancing component 11 includes a guide roller 1101 connected to the base frame 1 at both ends, a swing arm 1102 provided on the guide roller 1101, a protrusion 1103 and a counterweight 1104 respectively provided at both ends of the swing arm 1102, and an arc-shaped groove 1105 opened on the base frame 1 and slidingly engaged with the protrusion 1103. The thermal paper enters the coating area 12 through the guide roller 1101. When the material tension increases, the swing arm 1102 swings to drive the counterweight 1104 to balance the tension. When the tension decreases, the counterweight 1104 pulls the swing arm 1102 back to its original position by gravity, ensuring that the guide roller 1101 dynamically adjusts its position.

[0031] In an optional embodiment of this utility model, a spray nozzle 13 is provided on the base frame 1 below the protective film, and a hot air nozzle 14 is provided above the protective film. The spray nozzle 13 is used to spray adhesive onto the protective film, and the hot air nozzle 14 is used to blow hot air onto the protective film to heat it up, thereby improving the adhesion of the film. The pre-coating of adhesive combined with hot air curing enhances the bonding strength between the protective film and the thermal paper.
