Technical Field

[0001] The utility model relates to the technical field of foam board laminating, in particular to a sealing and cutting device for an automatic laminating machine. Background Art

[0002] When foam boards are produced, they often need to be coated. Coating can effectively protect the surface of the foam board from scratches, stains and daily wear and tear, thereby extending its service life. It can also improve the waterproof and moisture-proof properties of the foam board, preventing moisture penetration from causing deformation or damage to the board.

[0003] The existing Chinese patent with announcement number CN204936412U discloses a sealing and cutting machine for film packaging, including a base, on which a conveying mechanism and a sealing and cutting mechanism are provided. A film placing mechanism is provided above the conveying mechanism. The sealing and cutting mechanism includes a sealing and cutting knife holder, which is hinged with a scraper. The sealing and cutting knife holder includes a right bracket and a left bracket connected by a fixed plate. Both the right bracket and the left bracket are provided with mounting grooves, which have the advantage of quickly and accurately adjusting the distance between the sealing and cutting knife and the product.

[0004] Based on the above situation, the inventors believe that the current sealing and cutting knives are often directly exposed to the air and are often idle for a long time when not in use. This makes the sealing and cutting knives easily affected by moisture and air, causing rust and oxidation, which shortens their lifespan. Utility Model Content

The output end of the first driving member 12 is fixed to the knife holder 13, and the left and right ends of the knife holder 13 slide with the mounting plate 11. The outer side of the mounting plate 11 is fixed to the frame of the laminating machine. The sealing and cutting knife 14 is fixed to the bottom surface of the knife holder 13. The knife holder 13 is pushed down by the first driving member 12, so that the sealing and cutting knife 14 can move down synchronously, thereby realizing cutting of the laminated film.

[0034] Specifically, the top end of the L-shaped frame 2 is fixed to the mounting plate 11, and the L-shaped frame 2 can provide an installation space for the inner end of the protection component 3. The protection component 3 is fixed on the L-shaped frame 2, and the protection component 3 is kept in contact with the outer surface of the sealing and cutting knife 14, so that the protection component 3 provides dust and oxidation protection for the surface of the sealing and cutting knife 14.

[0035] Furthermore, the protection component 3 includes a push-pull component 4, an installation box 5, a connecting rod 6 and a protection plate 7. The push-pull component 4 and the installation box 5 are fixed to the outside of the L-shaped frame 2. The outside of the connecting rod 6 is slidably connected to the installation box 5. The protection plate 7 is in contact with the outer surface of the sealing and cutting knife 14, and the protection plate 7 is connected to the push-pull component 4 through the connecting rod 6. The connecting rod 6 is driven to move by the push-pull component 4, so that the protection plate 7 can be separated from or attached to the sealing and cutting knife 14, so that the protection plate 7 can be separated when the sealing and cutting knife 14 is in use, and the sealing and cutting knife 14 is protected by the protection plate 7 when it is placed daily.

[0036] For details, please refer to Figure 2 The push-pull assembly 4 includes a second driving member 41, a frame plate 42 and a push-pull plate 43. The outer side of the second driving member 41 is fixed to the L-shaped frame 2, the piston rod of the second driving member 41 is fixedly connected to the frame plate 42, and the bottom end of the frame plate 42 is fixed to the push-pull plate 43, so that when the piston rod of the second driving member 41 moves, the push-pull plate 43 can be driven to move left and right through the frame plate 42. A push opening 21 is provided on the L-shaped frame 2, and the push-pull plate 43 slides into the push opening 21 and is connected to the connecting rod 6. The outer wall of the push-pull plate 43 is slidably connected to the push opening 21, so that the push-pull plate 43 can stably realize push-pull movement, which is convenient for operation.

[0037] Among them, the installation box 5 includes a box body 51 and a mounting groove 52. The box body 51 is fixedly connected to the outer side of the L-shaped frame 2. The box body 51 slides with the connecting rod 6 through the mounting groove 52, so that the connecting rod 6 can slide along the mounting groove 52 after being pushed by the push-pull plate 43, thereby driving the protective plate 7 to be close to the sealing and cutting knife 14 or separate from it.

[0038] When implementing, please refer to Figure 3 The mounting groove 52 includes a slide groove 521 and a through groove 522. The slide groove 521 and the through groove 522 are opened inside the box body 51, and the slide groove 521 is arranged at two locations in the box body 51 in an upper and lower spacing manner. The upper part of the through groove 522 is connected to the two slide grooves 521, so that the two slide grooves 521 arranged above and below can respectively drive the connecting rods 6 at different positions at the front and rear to achieve synchronous movement.

[0039] Furthermore, there are two connecting rods 6 symmetrically arranged, and the two connecting rods 6 slide along separate sliding grooves 521 respectively, so that the connecting rods 6 can independently drive the protective plate 7 connected thereto to move synchronously, thereby realizing the fitting or separation operation of the protective plate 7 and the sealing and cutting knife 14.

The outer side of the push rod 44 is slidably connected to the push groove 64. The push groove 64 is an inclined structure. The top of the push rod 44 penetrates the through groove 522 and the slide groove 521 in sequence, so that when the push rod 44 is driven to the right by the push-pull plate 43, the push rod 44 can apply force to the slider 61 through the push groove 64, so that the slider 61 is retracted into the slide groove 521, so that the protective plate 7 is close to the sealing and cutting knife 14. When the push rod 44 moves to the left, the slider 61 is pushed outward, so that the protective plate 7 is separated from the sealing and cutting knife 14.

[0042] Furthermore, the protective plate 7 includes a pasting plate 71 and a contact pad 72. The outer side of the pasting plate 71 is fixedly connected to the fixed block 62, so that when the slider 61 moves, it can drive the fixed block 62 and the pasting plate 71 to move synchronously. A contact pad 72 is fixed on the inner side of the pasting plate 71. The pasting plate 71 is fitted with the outer surface of the sealing and cutting knife 14 through the contact pad 72. The material of the contact pad 73 is rubber, which can improve the contact effect between the pasting plate 71 and the sealing and cutting knife 14.

[0043] During implementation, the first driving member 12 and the second driving member 41 are of the type of a pneumatic cylinder, an oil cylinder or an electric push cylinder, thereby providing sufficient output force for the connected components to ensure stable operation of the equipment.

[0044] The control method of the present invention is to manually start and stop the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in the field. Moreover, the present invention is mainly used to protect mechanical devices.
