Description

Technical Field

[0002] In the existing film lamination technology, due to the limitations of equipment design and operation methods, there are often problems such as inaccurate positioning, complex operation and unstable lamination effect. These problems are particularly prominent when performing high-precision and high-efficiency film lamination work.

[0003] First, the traditional film laminating machine has obvious deficiencies in positioning. Due to the inaccurate and inflexible design of the limit device, the positioning of the sheet and film is often difficult to achieve the ideal state, which directly affects the accuracy and quality of lamination. At the same time, due to the lack of an effective guide mechanism, it is difficult for operators to ensure the accuracy of the position when placing the sheet and film, further increasing the possibility of lamination errors.

[0004] Secondly, the operational complexity of traditional equipment is also a major problem. When adjusting the spacing of the limit plates, the guide rollers and the height of the heating components, operators are often required to perform tedious manual adjustments, which not only reduces work efficiency, but also increases the difficulty of operation and the error rate. In view of this, we propose a preheating laminating machine for precise operation. Utility Model Content

By setting the first guide plate 70 on the limiting plate 7, the coated plate can be placed between the two limiting plates 7 to increase the accuracy of plate positioning. At the same time, the film can be pulled up above the second guide plate 71 during use, and then the film can be slowly placed between the two limiting plates 7 along the two second guide plates 71 to increase the accuracy of the film position, thereby increasing the accuracy of positioning between the film and the plate. A height-adjustable guide roller 4 is provided to facilitate use with plates of different heights, and a height-adjustable heating component is used to cooperate with the guide roller 4.

[0027] As a preferred embodiment of the present invention, a limiting cap 20 is fixedly connected to the top of the support column 2 by a fixing bolt 21, and the end of the film placement roller 3 is clamped and fixed between the top of the support column 2 and the limiting cap 20. This design makes the installation and removal of the film placement roller 3 simple and convenient, and improves the maintenance efficiency of the equipment.

[0028] As a preferred embodiment of the present invention, a driving block 40 is fixedly connected to both ends of the guide roller 4, and two first hydraulic cylinders 41 are installed on the bottom plate 1 for driving the two driving blocks 40 to move up and down, respectively, so as to adapt to plates of different thicknesses.

[0029] As a preferred embodiment of the present invention, the heating assembly includes two symmetrically arranged mounting blocks 61, two horizontal plates 6 are symmetrically fixedly connected between the two mounting blocks 61, a heating plate 60 is fixed on the outer wall of each of the horizontal plates 6 located on one side opposite to the other, and two second hydraulic cylinders 62 are installed on the bottom plate 1 for driving the two mounting blocks 61 to move up and down. The heating plate 60 in the heating assembly can preheat the material to improve the bonding effect.

[0030] As a preferred embodiment of the present invention, the driving mechanism 8 includes two screw rods 88 respectively fixedly connected to the outer wall of the limit plate 7 and two support plates 87 symmetrically fixed on the top of the base plate 1, and a knob 89 threadedly connected to the screw rod 88 is rotatably connected to the support plate 87, and a toothed ring 86 is coaxially welded to the outer wall of the knob 89. The driving mechanism 8 also includes a mounting box 81 fixed to the bottom of the base plate 1, and two driving rods 80 are symmetrically rotatably connected to the mounting box 81, and a first spur gear 84 is coaxially fixed to the end of each driving rod 80, and a second spur gear 85 is meshed above the first spur gear 84, and the second spur gear 85 is meshed with the toothed ring 86. The driving mechanism 8 realizes precise control of the limit plate 7 through the cooperation of the screw rod 88, the support plate 87, the knob 89 and the toothed ring 86. By rotating the knob 89, the screw rod 88 can be driven to move, thereby driving the limit plate 7 to move. This design makes the adjustment of the limit plate 7 simple and convenient, and has high precision.

[0031] As a preferred embodiment of the present invention, a bevel gear set 82 connected to both driving rods 80 is provided inside the installation box 81, and a driving motor 83 for driving the bevel gear set 82 is installed at the bottom of the installation box 81. A limiting slide groove 880 is provided on the outer wall of the screw rod 88, and the screw rod 88 is slidably connected to the support plate 87 left and right. The cooperation between the bevel gear set 82 and the driving motor 83 enables the two limiting plates 7 to move synchronously, further improving the automation degree and operation convenience of the equipment. At the same time, the design of the limiting slide groove 880 ensures the stability of the screw rod 88 during the movement, and improves the service life and reliability of the equipment.

[0032] When the precision preheating laminating machine of the utility model is used, first, the operator needs to install the film placement roller 3 on the support column 2 and fix it by fixing bolts 21 and limit caps 20. In this way, the film can be unrolled from the film placement roller 3, ready for subsequent laminating work, and the heating component is started at the same time.

[0033] Next, the operator needs to start the driving mechanism 8, drive the bevel gear set 82 through the driving motor 83, and then drive the two driving rods 80 to rotate. The first spur gear 84 on the driving rod 80 will drive the second spur gear 85 to rotate, thereby driving the knob 89 and the gear ring 86 to rotate. Since the knob 89 and the screw rod 88 are threadedly connected, the rotation of the knob 89 will drive the screw rod 88 to slide left and right on the support plate 87, thereby driving the limit plate 7 to move. In this way, the two limit plates 7 can move synchronously to the middle, and the distance between the two limit plates 7 can be adjusted to be equal to the width of the plate.

[0034] Next, according to the thickness of the plate to be laminated, the operator needs to adjust the height of the guide roller 4 and the heating assembly. This is achieved by controlling the first hydraulic cylinder 41 and the second hydraulic cylinder 62, which can respectively drive the guide roller 4 and the heating assembly to move up and down to adapt to plates of different thicknesses.

[0035] Then, the operator needs to place the plate to be coated between the two limit plates 7. In this process, the first guide plate 70 can play a guiding role, helping the operator to place the plate more accurately. At the same time, the second guide plate 71 can help the operator to place the film on the plate more accurately.

[0036] Finally, press the sheet and film together to complete the bonding process.
