Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts are within the scope of the present application.

[0029] Please refer to Figures 1-4 In the embodiments of the present application, a laminating device for printed matter comprises a rack 1 and a laminating device arranged on the rack 1. The rack 1 has a workbench 2. The laminating device comprises a base material feeding mechanism 3 arranged below the front end of the workbench 2, a laminating material feeding mechanism 4 arranged above the front end of the workbench 2, a composite mechanism 5 arranged at one side of the front end of the workbench 2, and a winding mechanism 6 arranged below the rear end of the workbench 2.

[0030] The base material feeding mechanism 3 and the laminating material feeding mechanism 4 are used to respectively feed the base material and the laminating material to the composite mechanism 5. The composite mechanism 5 is used to combine the base material and the laminating material and feed them to the workbench 2. The winding mechanism 6 is used to wind the finished product or semi-finished product formed by the base material after being laminated on the workbench 2.

[0031] In the technical solutions of the present application, the laminating device forms an organic whole by reasonably distributing various functional mechanisms on the rack 1. The workbench 2 serves as an operation platform. The base material feeding mechanism 3 is arranged below the front end of the workbench 2, which facilitates the stable feeding of the base material. The laminating material feeding mechanism 4 is arranged above the front end of the workbench 2, corresponding to the base material feeding mechanism 3, which ensures that the laminating material accurately covers the base material. The composite mechanism 5 is arranged at one side of the front end of the workbench 2, which facilitates the receiving of the base material and the laminating material from the feeding mechanisms and the combination operation. The winding mechanism 6 is arranged below the rear end of the workbench 2, which can timely wind the finished product or semi-finished product after being laminated. The base material feeding mechanism 3 and the laminating material feeding mechanism 4 are respectively responsible for feeding the base material and the laminating material to the composite mechanism 5. They cooperate with each other to ensure the accurate supply of the materials. The composite mechanism 5 uses specific technical means, such as hot pressing or adhesive, to tightly combine the base material and the laminating material together and feed the combined materials to the workbench 2. The winding mechanism 6 winds the finished product or semi-finished product on the workbench 2, thereby completing the whole laminating process.

[0032] In summary, the design integrates the base material feeding mechanism 3, the film feeding mechanism 4, the compounding mechanism 5 and the winding mechanism 6 on the rack 1, realizes the integrated design, avoids the disadvantages of scattered and independent operation of various functional modules, so that the whole film covering process is more smooth, and the efficiency is improved; the position layout of the base material feeding mechanism 3 and the film feeding mechanism 4 is optimized, and they are located below and above the front end of the workbench 2 respectively, avoiding the problems of unsmooth feeding and material deviation in the traditional equipment, so that the material conveying is more stable and accurate, and the film covering precision and quality are improved.

[0033] In the embodiment of the utility model, the base material feeding mechanism 3 includes base material feeding roller 7 and base material guiding assembly, base material feeding roller 7 is guided by the base material guiding assembly and is transported to compounding mechanism 5,

[0034] The base material guiding assembly is provided with at least one base material guiding roller 8, and the surfaces of the base material guiding roller 8 and the base material feeding roller 7 are respectively provided with forward screw structure 9 and reverse screw structure 10.

[0035] The base material feeding roller 7 is the driving conveying component, and the base material guiding roller 8 in the base material guiding assembly plays a guiding and auxiliary conveying role, so that the base material is accurately conveyed to the compounding mechanism 5 according to the predetermined path, and the problems of inaccurate film covering position, material waste and the like caused by base material deviation are effectively avoided, and the film covering precision and quality are improved.

[0036] The surfaces of the base material guiding roller 8 and the base material feeding roller 7 are respectively provided with forward screw structure 9 and reverse screw structure 10, and the principle is that the lateral force generated by the difference in the rotation direction of the screw is used to position and adjust the base material horizontally, when the base material moves on the roller, the screw structures on both sides will exert a centripetal force on the base material, so that the base material always remains at the center position of the roller, preventing the base material from deviating during conveying, and the base material feeding mechanism 3 with bidirectional screw structure can be adjusted according to the specific conditions of the base material, and is suitable for base materials of different thicknesses, widths and materials, improving the versatility and adaptability of the equipment.

[0037] Furthermore, the base material feeding roller 7 can also be connected with the printing equipment, and the printing equipment conveys the base material to the base material feeding roller 7, that is, after the printing equipment completes the printing process of the base material, the discharge port of the printing equipment is connected with the base material feeding roller 7 through the transmission belt or the transmission chain, so that the continuous operation of printing-film covering is realized.

[0038] In the embodiment of the utility model, the forward thread structure 9 is arranged along one side of the base material guiding roller 8 or the base material feeding roller 7 towards the middle, and the reverse thread structure 10 is arranged along the other side of the base material guiding roller 8 or the base material feeding roller 7 towards the middle.

[0039] The forward thread structure 9 is arranged along one side of the base material guiding roller 8 or the base material feeding roller 7 towards the middle, and the reverse thread structure 10 is arranged along the other side towards the middle, which makes the threads on both sides generate a force gathering the base material to the center when the base material moves on the roller. During the process that the base material contacts the base material guiding roller 8 or the base material feeding roller 7, the base material is automatically adjusted in position and moves to the center of the roller due to the inclination angle and rotation direction of the threads. For example, when the base material has a tendency to deviate to one side, the reverse thread on the side will apply a counteracting force to the center of the base material to prevent the base material from continuing to deviate, and the forward thread on the other side will also assist in pulling the base material back to the center position.

[0040] In the embodiment of the utility model, the film feeding mechanism 4 comprises a film feeding roller 11 and a film guiding assembly, and the film feeding roller 11 is guided by the film guiding assembly to deliver the film to the composite structure.

[0041] The film guiding assembly comprises a first fixed seat 12 arranged on the end surface of the workbench 2, an elastic hinged component and a film guiding roller 13, one end of the film feeding roller 11 is rotatably connected to the first fixed seat 12, one end of the film guiding roller 13 is arranged on the outer side of the first fixed seat 12 through the elastic hinged component and corresponds to the film feeding roller 11, and the film guiding roller 13 can approach or move away from the film feeding roller 11 through the elastic hinged component.

[0042] The film feeding mechanism 4 is composed of the film feeding roller 11 and the film guiding assembly. The film feeding roller 11 serves as a driving delivery component and moves the film material forward by rotating. The first fixed seat 12 in the film guiding assembly provides support and mounting position for the film feeding roller 11 and the film guiding roller 13. One end of the film feeding roller 11 is rotatably connected to the first fixed seat 12 to ensure that it can stably rotate to deliver the film material. One end of the film guiding roller 13 is arranged on the outer side of the first fixed seat 12 through the elastic hinged component and corresponds to the film feeding roller 11. The elastic hinged component enables the film guiding roller 13 to approach or move away from the film feeding roller 11.

[0043] Specifically, in the high-speed film covering process, the film material between the film feeding roller 11 and the film guide roller 13 is affected by various dynamic forces, such as motor vibration, uneven mechanical transmission, etc., thereby generating jitter, and the elastic hinged component can absorb and relieve the impact force generated by the jitter through its elastic deformation; when the film material jitters, the elastic hinged component will stretch or bend according to the direction and amplitude of the jitter, so that the film guide roller 13 can move slightly relative to the film feeding roller 11, thereby reducing the instantaneous impact force on the film material and playing a buffering role.

[0044] The elastic hinged component not only buffers the jitter, but also dynamically adjusts the pressure and gap between the film guide roller 13 and the film feeding roller 11 in the high-speed film covering process. When the jitter causes the thickness or position of the film material to change, the elastic hinged component will automatically adjust the position of the film guide roller 13 to maintain proper pressure and guidance on the film material, ensuring stable delivery of the film material.

[0045] In the utility model embodiment, the elastic hinged component comprises a first connecting piece 14, a second connecting piece 15 and an elastic piece 16, the first connecting piece 14 is arranged on the first fixed seat 12, one end of the second connecting piece 15 is hinged to the first connecting piece 14, the other end of the second connecting piece 15 extends to the outside of the first fixed seat 12, one end of the film guide roller 13 is rotatably connected to the extended end of the second connecting piece 15, wherein one end of the elastic piece 16 is connected to the first fixed seat 12, and the other end of the elastic piece 16 is connected to the extended end of the second connecting piece 15.

[0046] The elastic hinged component is composed of the first connecting piece 14, the second connecting piece 15 and the elastic piece 16 (spring), the first connecting piece 14 is fixed on the first fixed seat 12 and serves as the basic connecting point of the entire elastic hinged component, one end of the second connecting piece 15 is hinged to the first connecting piece 14, so that the second connecting piece 15 can rotate at a certain angle relative to the first connecting piece 14, the other end of the second connecting piece 15 extends to the outside of the first fixed seat 12, and one end of the film guide roller 13 is rotatably connected to the extended end;

[0047] One end of the elastic piece 16 is connected to the first fixed seat 12, and the other end is connected to the extended end of the second connecting piece 15. During the film covering process, when the film material jitters or is impacted by other external forces, the film guide roller 13 will transmit the force to the elastic piece 16 through the second connecting piece 15, and the elastic piece 16 will elastically deform according to the force condition, thereby playing a buffering role;

[0048] Specifically, in the high-speed film coating process, if the film coating material produces shaking, the shaking force will first act on the film coating guide roller 13, since the film coating guide roller 13 is rotationally connected to the second connecting piece 15, the force will be transmitted to the second connecting piece 15, the second connecting piece 15 rotates relative to the first connecting piece 14, and the elastic member 16 is deformed by stretching or compression, the elastic member 16 resists the deformation by the elastic restoring force of itself, thereby absorbing and buffering the impact force generated by the shaking; for example, when the film coating material is suddenly offset to one side by a larger impact force, the film coating guide roller 13 will move in that direction, driving the second connecting piece 15 to rotate, so that the elastic member 16 is stretched, and the stretching force of the elastic member 16 will act on the second connecting piece 15 and the film coating guide roller 13, so that they gradually return to the equilibrium position, thereby reducing the offset amplitude and the shaking degree of the film coating material.

[0050] The composite mechanism 5 is arranged at the front end of the workbench 2 and mainly composed of the second fixing base 17, the supporting roller 18, and the pressing roller 19, the second fixing base 17 provides installation and support for the supporting roller 18 and the pressing roller 19, the supporting roller 18 corresponds to the base material guide roller 8 and is used for supporting the base material conveyed from the base material feeding mechanism 3, so as to ensure that the base material maintains a stable position and state when entering the composite process, the pressing roller 19 corresponds to the film coating guide roller 13 and is used for pressing the film coating material conveyed from the film coating feeding mechanism 4 on the base material to realize the combination of the base material and the film coating material, and the supporting roller 18 and the pressing roller 19 rotationally connected to the second fixing base 17 can rotate under the driving of a motor or other power device, the friction force generated by the rotation drives the base material and the film coating material to move forward, and the composite process is completed under the pressure of the pressing roller 19.

[0051] In the embodiment of the utility model, the composite mechanism 5 further includes a pressure adjusting assembly.

[0054] When it is necessary to adjust the laminating pressure, an operator rotates the knob 21, since the knob 21 is threadedly connected to the sliding block 20, the rotation of the knob 21 will be converted into the linear motion of the sliding block 20 on the guide rail, if the knob 21 is rotated clockwise, the sliding block 20 will move along the guide rail to the direction of approaching the supporting roller 18, so as to reduce the distance between the compression roller 19 and the supporting roller 18 and increase the pressure of the compression roller 19 to the film material and the base material, on the contrary, if the knob 21 is rotated counterclockwise, the sliding block 20 will move to the direction of moving away from the supporting roller 18, so as to increase the distance between the compression roller 19 and the supporting roller 18 and reduce the pressure of the compression roller 19.
