Description

Technical Field

[0001] The utility model relates to the technical field of foam processing equipment, in particular to a foam structure film laminating tooling. Background Art

[0002] In modern industrial production, the packaging of electrical products is a key link to ensure the safety and integrity of products during transportation and storage. Although traditional foam packaging materials have good cushioning performance, there are some limitations in actual applications. For example, foam materials are vulnerable to scratching and abrasion, are prone to adsorbing dust and pollutants, and are easy to absorb water in a humid environment, affecting the protection performance and service life of the packaging.

[0003] In view of the above problems, the prior art proposes to bond a layer of plastic film at the bottom of the foam material as a protective layer, which can not only provide additional protection for the foam material to prevent scratching and abrasion, but also effectively prevent moisture and water, enhance the structural stability of the packaging, improve the overall aesthetics of the electrical packaging products, and enhance the user experience.

[0004] However, the problem of the prior art is that, as Figure 1 shown, the foam board 1 for packaging electrical appliances is mostly square in structure. The plastic film 2 not only needs to cover the bottom surface of the foam board 1 ( Figure 1 the shown foam board 1 is in an inverted state), but also needs to cover the position on the side wall close to the bottom surface with a height of about 3 - 5 cm. However, the existing film laminating equipment can only press the plastic film 2 on the bottom surface from top to bottom. The plastic film 2 on the side wall of the foam board 1 can only be manually pressed by workers or rolled and pressed by using a pressing roller, which not only has low working efficiency and poor bonding effect, but also easily leaves air bubbles between the foam board 1 and the plastic film 2, and the edge of the plastic film 2 is also prone to warping problems. Therefore, there is an urgent need for a film laminating tooling that is easy to disassemble and can be assembled to the existing film laminating equipment to effectively press the plastic film 2 on the side wall of the foam board 1. Summary of the Utility Model

[0005] The utility model provides a foam structure film laminating tooling, which can solve the technical problem of poor pressing effect of the plastic film on the side wall of the foam board.

[0006] The present application provides the following technical solutions:

[0007] The foam structure film laminating tooling includes a mounting plate detachably connected to the film laminating equipment, a telescopic mechanism slidably connected to the mounting plate, a connecting plate fixedly connected to the telescopic end of the telescopic mechanism, a hot pressing plate detachably connected to the side of the connecting plate far from the mounting plate. The surface of the hot pressing plate far from the mounting plate is a plane, and it also includes a control mechanism for controlling the movement of the telescopic mechanism and heating the hot pressing plate.

[0008] Beneficial Effects:

[0009] 1. Improve the lamination effect: In this solution, the telescopic mechanism drives the hot pressing plate under the control of the control mechanism to specifically hot-press the plastic film on the side wall of the foam board, that is, the edge position of the plastic film. The side of the hot pressing plate away from the mounting plate, namely the heating surface, is a plane. Compared with the traditional solutions that rely on manual pressing by workers and using pressing rollers for lamination, it is beneficial to eliminate the residual bubbles and edge warping problems between the foam board and the plastic film, thereby improving the overall lamination effect.

[0010] 2. Expand the scope of use: The telescopic mechanism is connected to the mounting plate in a sliding connection manner, enabling the height positions of the telescopic mechanism and the hot pressing plate to be adjusted within the sliding range, so as to adapt to the film covering processing of foam boards of different specifications, which is beneficial to expanding the scope of use.

[0011] 3. A connecting plate is added between the hot pressing plate and the telescopic mechanism, which is beneficial for heat insulation and can prevent the telescopic mechanism from malfunctioning due to heat.

[0012] Furthermore, as an improvement, it also includes a limiting plate for fixing the telescopic mechanism. A plurality of limiting holes are fixedly arranged on the mounting plate along the sliding direction of the telescopic mechanism, and the limiting plate is detachably connected to the limiting holes.

[0013] Beneficial effect: The limiting plate is set to limit the sliding of the telescopic mechanism on the mounting plate, so that the hot pressing plate always maintains the same height to continuously press the plastic film.

[0014] Furthermore, as an improvement, the film covering equipment includes a gantry, and the mounting plate and the gantry are connected by screw threads.

[0015] Beneficial effect: Installing the mounting plate on the gantry enables this tooling to adapt to existing film covering equipment, improving its operability and convenience.

[0016] Furthermore, as an improvement, the control mechanism includes a PLC with an external power supply. The telescopic mechanism is selected as an electric telescopic rod, and the PLC is electrically connected to the hot pressing plate and the electric telescopic rod respectively.

[0017] Beneficial effect: As a general industrial automatic control device, the PLC has a series of advantages such as high reliability, small volume, strong function, simple program design, flexible generality, and convenient maintenance. Using the PLC to centrally control the hot pressing plate and the electric telescopic rod is beneficial for the convenience of workers when operating the equipment, and the heating temperature of the hot pressing plate and the telescopic amount of the electric telescopic rod can both be adjusted through the PLC.

[0023] The following is a further detailed description through specific embodiments:

[0024] The marks in the attached drawings of the specification include: foam board 1, plastic film 2, mounting plate 3, chute 31, electric telescopic rod 4, telescopic end 41, base 42, connecting plate 5, hot pressing plate 6, limiting plate 7, limiting hole 71, mating hole 72, gantry 8, frame one 81, frame two 82, frame three 83, crawler 9.

[0025] Embodiment 1

[0026] Combined with Figures 2 - 4 as shown, the foam structure film covering tooling includes a mounting plate 3, an electric telescopic rod 4 slidably connected to the mounting plate 3, a connecting plate 5 fixedly connected to the electric telescopic rod 4 by screws, a hot pressing plate 6 detachably connected to the side of the connecting plate 5 far from the mounting plate 3 by screws, and a control mechanism for centralized control.

[0027] Two vertical chutes 31 are fixedly arranged on the mounting plate 3. The cross-section of the chute 31 is a trapezoidal structure. The electric telescopic rod 4 includes a telescopic end 41 and a base 42. Two sliders with the same trapezoidal structure and adapted to the chute 31 are fixedly arranged on the side of the base 42 far from the telescopic end 41. The sliders are in clearance fit with the chute 31 and can slide vertically along the chute 31 on the mounting plate 3 to adjust the position height of the hot pressing plate 6.

[0028] In this embodiment, the control mechanism includes a PLC with an external power supply. The telescopic mechanism selects the electric telescopic rod 4. The PLC is electrically connected to the hot pressing plate 6 and the electric telescopic rod 4 through wires respectively to achieve the functions of controlling the movement of the telescopic end 41 on the electric telescopic rod 4 and heating the hot pressing plate 6. The hot pressing plate 6 is a square structure as a whole, so that the side of the hot pressing plate 6 far from the mounting plate 3 is a plane. The hot pressing plate 6 is hollow inside and an electric heating wire is fixedly installed. The electric heating wire is electrically connected to the PLC through a wire.

[0029] The electric telescopic rod 4 is also provided with a limit plate 7. When the height position of the hot pressing plate 6 is determined, the limit plate 7 is required to limit the electric telescopic rod 4 as a whole. Figure 3 As shown, they are distributed vertically with the slide groove 31. Three groups of limiting holes 71 are fixedly set on the mounting plate 3 along the slide groove 31. Matching holes 72 with the same specifications as the limiting holes 71 are fixedly set on both sides of the limiting plate 7. Both the limiting holes 71 and the matching holes 72 are internal threaded holes. The matching holes 72 and the limiting holes 71 are threadedly connected in sequence by installing screws, so that the limiting plate 7 is installed on the mounting plate 3 to limit the downward movement of the electric telescopic rod 4.

[0030] In this embodiment, the width of the hot pressing plate 6 is 15 cm, which is greater than the width of the plastic film 2 on the side wall of the corresponding foam board 1 .

[0031] The specific application process is as follows:

[0032] like Figure 5 As shown, the existing laminating equipment includes a gantry 8 for supporting the whole set of equipment and a crawler 9 for inverting and conveying the foam board 1, so that the bottom surface of the foam board 1 is as shown in FIG. Figure 1 As shown, the foam board 1 is placed upward, and a pressing mechanism is installed on the top of the gantry 8 to press the plastic film 2 located on the bottom surface of the foam board 1.

[0033] When in use, the mounting plate 3 is fixed on the gantry 8 by screws, and then the electric telescopic rod 4 with the connecting plate 5 and the hot pressing plate 6 fixed in advance is slidably installed in the slide groove 31 on the mounting plate 3. As for the height position of the base 42 on the electric telescopic rod 4 on the mounting plate 3, it is based on the standard that the hot pressing plate 6 can completely cover the plastic film 2 on the side wall of the foam board 1, and at least one group of limiting holes 71 is required to be exposed outside the hot pressing plate 6, and then the limiting plate 7 is used to limit the electric telescopic rod 4 as a whole. Specifically, the matching holes 72 on the limiting plate 7 correspond to the limiting holes 71 on the mounting plate 3, and then the matching holes 72 and the limiting holes 71 are threadedly connected in sequence with screws. Finally, the base 42 of the electric rope rod is slidably installed from the top position of the slide groove 31 and contacts the limiting plate 7. The setting of the limiting plate 7 and the design of the trapezoidal slide groove 31 ensure that the base 42 will not separate from the mounting plate 3.

[0034] Then, the PLC is used to control the heating of the hot pressing plate 6. When the temperature of the hot pressing plate 6 reaches a certain level, the PLC starts the electric telescopic rod 4 to drive the hot pressing plate 6 to press the plastic film 2 on the side wall of the foam board 1. At the same time, the track 9 will also drive the foam board 1 to move forward to ensure the continuous pressing of the hot pressing plate 6 on the plastic film 2. In this embodiment, the gantry includes frame 1 81, frame 2 82, and frame 3 83. A foam structure laminating tool is installed on frame 1 81, frame 2 82, and frame 3 83.

[0035] This solution designs a foam structure film laminating tooling that is easy to install on the gantry 8, and performs a flat and continuous hot pressing action on the plastic film 2 on the side wall of the foam board 1, which can ensure the effect of laminating the plastic film 2 on the foam board 1 and avoid problems such as air bubbles and warping edges.

[0036] The above are only embodiments of the present utility model. The present utility model is not limited to the fields involved in this embodiment. Common knowledge such as specific structures and characteristics known in the solution is not described in detail here. It should be noted that for those skilled in the art, without departing from the structure of the present utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the present utility model, and these will not affect the implementation effect of the present utility model and the practicability of the patent. The protection scope required by this application should be based on the content of its claims, and the specific implementation manners described in the specification can be used to interpret the content of the claims.
