Description

Technical Field

[0001] This invention relates to the field of stationery manufacturing equipment technology, specifically to a coating device for a rewritable and erasable notebook. Background Technology

[0002] Erasable and rewritable notebooks, also known as whiteboard notebooks or erasable notepads, are widely used in office and education fields due to their environmentally friendly characteristics of being able to be repeatedly erased and rewritten. The writing surface of these notebooks is usually made of hard whiteboard material. During production, transportation, and storage, a transparent protective film needs to be applied to the surface to prevent scratches and stains, ensuring the writing performance after leaving the factory.

[0003] In existing technologies, the lamination process for notebook computer boards has the following main technical drawbacks: 1. Separation of processes makes it difficult to balance efficiency and precision: Film rolling and edge trimming are two independent processes. First, the film is laminated by the rolling mechanism, and then it is transferred to an independent cutting device for edge trimming. The process flow is long and the production efficiency is low.

[0004] 2. Independent cutting drive, high equipment cost and failure rate: The cutting mechanism is mostly driven by independent cylinders, motors and other power components, which not only increases the overall size and manufacturing cost of the equipment, but also requires an independent control system to match the rolling stroke and cutting timing, resulting in a high equipment failure rate and high maintenance costs.

[0005] Therefore, there is an urgent need for a laminating device that integrates pressure rollers and cutting to improve efficiency for rewritable and erasable notebooks. Summary of the Invention

[0006] The purpose of this invention is to provide a laminating device for a rewritable notebook, in order to solve the problems mentioned in the background art of existing laminating equipment, such as the separation of rolling and cutting processes, independent cutting drive, and low equipment integration.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a laminating device for a rewritable notebook, comprising a frame base and a film material unwinding and winding mechanism mounted on the frame base.

The pressure roller lateral movement transmission mechanism is provided with an eccentric transmission part. The eccentric transmission part is driven downward to cooperate with the movable roller frame mechanism. The movable roller frame mechanism is assembled inside the mounting box. The floating cutting blade assembly is connected to the periphery of the mounting box. When the pressure roller lateral movement transmission mechanism drives the movable roller frame mechanism to move laterally to the end of the stroke, the movable roller frame mechanism drives the floating cutting blade assembly to move downward. The blade of the floating cutting blade assembly performs closed-loop cutting on the edge of the film.

The roller body gap compensation pressure frame 530 is fixedly connected to the middle of the upper connecting frame assembly 510.

[0028] A single servo motor 411 drives the worm gear body 412, which synchronously drives the two transmission worm wheels 421 on both sides to rotate. The rotational motion is converted into the transverse reciprocating linear motion of the rolling roller assembly 520 through the eccentric connecting column 424 and the linkage wheel 425. The entire transmission structure is integrated inside the mounting box 320, which has a high space utilization rate. Moreover, the worm gear transmission has self-locking properties, and the rolling position is stable without slippage. Only a single servo motor 411 needs to be controlled to complete the entire rolling and cutting process. The control system is greatly simplified, and the equipment failure rate and maintenance costs are significantly reduced.

The double pressure rollers achieve double-pass rolling, while the middle pressure plate 532 makes up for the gap blind area between the two rollers, so that the protective film of the entire surface of the notebook board is pressed down, effectively eliminating bubbles and lifting defects, and greatly improving the product coating yield.

[0031] Furthermore, the upper connecting frame assembly 510 includes a frame body 511, a guide rod frame 512, and a worm gear bearing seat 513.

The pressure roller column 523 is rotatably connected to the lower part of the roller mounting frame 521 along the longitudinal direction, and the side vertical plate 525 is fixed.

[0033] In some embodiments of the present invention, reference is made to... Figure 5 - Figure 6 and Figure 11 - Figure 12 As shown, the floating cutting blade assembly 600 includes a blade holder body assembly 610 and a guide reset assembly 620. The blade holder body assembly 610 is slidably mounted on the outside of the mounting box 320 in the vertical direction via the guide reset assembly 620. The guide reset assembly 620 provides vertical sliding guidance and upward reset elasticity for the blade holder body assembly 610.

[0034] Furthermore, the main body assembly 610 of the blade holder includes a floating blade holder frame 611, a frame-shaped cutting blade 612, and a wedge-shaped triggering block 613. The floating blade holder frame 611 has a rectangular frame structure and surrounds the outer periphery of the mounting box 320. The frame-shaped cutting blade 612 is fixed to the lower edge of the floating blade holder frame 611, with the cutting edge of the frame-shaped cutting blade 612 facing downward. The wedge-shaped triggering block 613 is symmetrically fixed to the two transverse ends of the upper part of the floating blade holder frame 611. The inclined surface of the wedge-shaped triggering block 613 faces upward and is arranged in the direction of movement of the cutting triggering shaft 526, for pressing and engaging with the cutting triggering shaft 526.

[0035] Furthermore, the guide reset assembly 620 includes an upper fixed mounting base 621, a guide rod 622, a lower fixed mounting base 623, a lower stop block 624, and a reset spring 625. The upper fixed mounting base 621 is fixedly connected to the four corners of the upper end of the mounting box 320, and the lower fixed mounting base 623 is fixedly connected to the four corners of the floating tool holder frame 611. The upper end of the guide rod 622 is fixedly connected to the upper fixed mounting base 621 and passes through the lower fixed mounting base 623. The lower stop block 624 is fixedly connected to the lower end of the guide rod 622. The reset spring 625 is sleeved on the outer periphery of the guide rod 622. The upper end of the reset spring 625 is connected to the lower end face of the lower fixed mounting base 623, and the lower end of the reset spring 625 is connected to the top surface of the lower stop block 624.

[0036] The eccentric transmission structure of the pressure roller transverse transmission mechanism 400 drives the rolling roller assembly 520 to move laterally to complete the film rolling. At the end of the rolling stroke, the cutting trigger shaft 526 cooperates with the inclined surface of the wedge trigger inclined block 613 to automatically trigger the floating cutting knife assembly 600 to descend for cutting. No independent cutting drive element and additional control process are required. Rolling and edge closed-loop cutting can be completed in one press, saving process flow and greatly improving production efficiency.

[0037] Working principle: The roll of transparent protective film is installed on the feed shaft of the feed roll frame 210. The end of the protective film is pulled around the guide roller of the right guide roller frame 220, passes smoothly over the laminating worktable 130, then around the left guide roller frame 220, and finally fixed on the take-up shaft of the take-up roll frame 230. The rewritable notebook to be laminated is placed on the positioning station of the laminating worktable 130, with the whiteboard side of the notebook facing up and directly below the protective film.

[0038] At this time, the pressing drive cylinder 310 is in the retracted state, the mounting box 320 is raised as a whole, and the pressure roller column 523 and the frame-shaped cutting blade 612 are both higher than the surface of the protective film; the reset spring 625 is in the naturally extended state, the floating blade frame 611 is in the upper limit position, and at this time the wedge-shaped triggering block 613 is higher than the guide through-strip opening 321.

[0039] The pressing drive cylinder 310 is activated, and the piston rod extends downward, pushing the mounting box 320 to descend smoothly in the vertical direction, driving the movable rolling roller frame mechanism 500 and the floating cutting blade assembly 600 to descend synchronously; until the roller surface of the pressure roller column 523 and the bottom surface of the pressure plate 532 press against the surface of the protective film, evenly pressing the protective film onto the laptop board surface, the pressing drive cylinder 310 maintains pressure and stops operating.

[0040] During this process, the frame-shaped cutting blade 612 descends synchronously with the mounting box 320, but still does not contact the surface of the protective film and remains in the upper position to be cut.

[0041] The servo motor 411 is started, which drives the worm gear body 412 to rotate at a constant speed. Through the meshing transmission of the worm gear and worm wheel, the transmission worm wheels 421 on both sides are driven to rotate synchronously around the worm wheel mounting shaft 423 in the same direction. When the transmission worm wheel 421 rotates, the eccentric connecting column 424 on the lower end face drives the linkage wheel 425 to perform eccentric circular motion. The linkage wheel 425 rolls in the linkage groove 524, pushing the roller mounting frame 521 to move laterally from one end of the stroke to the other along the guide rod frame 512.

[0042] Two sets of roller assemblies 520 move synchronously in opposite directions from the middle position to the left and right sides. The roller column 523 performs double-pass continuous rolling on the protective film, flatly adhering the protective film to the laptop board surface and expelling air under the film. At the same time, the pressure plate 532 in the middle position is always pressed against the area between the two rollers to compensate for insufficient pressure in the middle gap, ensuring that the entire laptop board surface is tightly adhered and completely eliminating defects such as air bubbles and poor adhesion.

[0043] During the rolling process, the cutting trigger shaft 526 moves laterally along the guide through-strip opening 321. Before contacting the wedge trigger block 613, the floating cutting tool assembly 600 remains in the upper position and does not interfere with the rolling operation.

[0044] When the transmission worm gear 421 rotates to the half-circle position, the roller mounting bracket 521 moves to the end of the transverse stroke, and the cutting trigger shaft 526 moves synchronously to the top of the wedge trigger block 613 and rolls along the inclined surface of the wedge trigger block 613. Through the component force of the inclined surface, the cutting trigger shaft 526 presses the wedge trigger block 613 downward, pushing the floating knife holder frame 611 to overcome the elastic force of the return spring 625 and slide smoothly vertically downward along the guide column rod 622.

[0045] The floating blade holder frame 611 descends, causing the frame-shaped cutting blade 612 to descend synchronously. The blade edge vertically cuts the four edges of the protective film, completing a rectangular closed-loop cut in one go.

[0046] After the cutting is completed, the servo motor 411 continues to rotate, and the transmission worm gear 421 enters the second half of the rotation, driving the roller mounting frame 521 to move laterally in the return direction; the cutting trigger shaft 526 gradually disengages from the wedge trigger block 613 along the inclined plane, the downward pressure gradually disappears, and the floating blade holder frame 611 slowly returns to its original position along the guide post 622 under the elastic force of the return spring 625, and the frame-shaped cutting blade 612 is lifted and detached from the film surface.

[0047] During the return stroke of the roller mounting frame 521, the pressure roller column 523 performs secondary rolling on the protective film to further compact the film material and ensure the bonding effect. When the roller mounting frame 521 returns to the initial position, the servo motor 411 stops rotating, completing one rolling and cutting cycle.
