Description

Technical Field

[0001] This utility model relates to the field of automatic laminating machine technology, specifically an automatic laminating machine. Background Technology

[0002] For pulp-molded paper products (such as lunch boxes and cup lids), some products require an inner film coating due to waterproofing needs. Because the products are three-dimensional and have a certain depth, and the coating layer must adhere tightly to the inner cavity, a vacuum environment is necessary during coating (the three-dimensional structure of the products makes it impossible to use a pressing or laminating method). In pulp-molded paper product coating equipment, film transport is a key technology.

[0003] Currently, there are two film feeding methods in the industry. The first is to feed the film through the cyclical operation of the mold, and the second is to feed the film through a film clamping chain. However, the former requires three molds, making the machine structure complex, while the latter leaves residual film edges and products, requiring the addition of a waste film collection device at the back of the machine, which is also complex and occupies a large area.

[0004] In traditional equipment, if the membrane is too close to the product during the membrane preheating process, wrinkles may form on the membrane material, affecting the coating effect. Conversely, if the membrane is too far from the product during the coating process, the coating effect will also be affected. Therefore, an automatic coating machine has been developed. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic film coating machine, comprising a frame, wherein the frame comprises a first mounting frame, a second mounting frame and a third mounting frame arranged sequentially from top to bottom and integrally formed;

[0007] The first mounting frame is provided with a lifting module, and a heating module is installed on the movable end of the bottom of the lifting module.

The pressing mechanism is located at the beginning of the second mounting frame, and the sealing mechanism includes a plurality of lifting cylinders and an upper sealing frame connected to the plurality of lifting cylinders.

[0009] The third mounting frame is equipped with a lifting module 2. The movable end of the top of the lifting module 2 is equipped with an air chamber mechanism. The sealing mechanism also includes several lifting cylinders 5 arranged around the air chamber mechanism. The several lifting cylinders 5 are connected to a lower sealing frame. The upper sealing frame, the lower sealing frame and the air chamber mechanism are adapted to each other in shape.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] Please see Figures 1 to 6 An embodiment of this utility model is provided: an automatic film coating machine, including a frame 100, the frame 100 including a first mounting frame 10, a second mounting frame 20 and a third mounting frame 30 arranged sequentially from top to bottom and integrally formed a three-layer frame 100;

[0031] The first mounting frame 10 is equipped with a lifting module 1, and a heating module 2 is installed at the movable end of the bottom of the lifting module 1. The second mounting frame 20 is equipped with a feeding mechanism 3, a pressing mechanism 4, and a sealing mechanism 5. The pressing mechanism 4 is located at the beginning of the second mounting frame 20. The third mounting frame 30 is equipped with a film feeding rack 6 at its end, which is close to the pressing mechanism 4. The film feeding rack 6 is mainly used for loading roll film. The third mounting frame 30 is equipped with a second lifting module 7, and an air chamber mechanism 8 is installed at the movable end of the top of the second lifting module 7. The air chamber mechanism 8 is adapted to the shape of the upper sealing frame 22. The system realizes the workflow of positioning, pressing, clamping, feeding, sealing, and cutting film, making the equipment structure simpler and the footprint smaller.

[0032] Furthermore, the side of the frame 100 is also provided with a manual standing groove 9, which can be used for automatic feeding and picking, or for operators to manually feed and pick up materials in the manual standing groove. The structure is simpler and occupies less space.

[0033] In this embodiment, the feeding mechanism 5 includes a drive shaft 23, two racks 24, and a first propulsion cylinder 25. The first propulsion cylinder 25 is fixedly mounted on a second mounting bracket 20. The two racks 24 are parallel to each other and slidably connected to the second mounting bracket 20. The propulsion end of the first propulsion cylinder 25 is rotatably connected to the drive shaft 23. Synchronous gears 26 are connected to both sides of the drive shaft 23, and the two synchronous gears 26 mesh with the two racks 24 respectively. Each rack 24 is equipped with a second propulsion cylinder 27. The transmission directions of the second propulsion cylinder 27 and the first propulsion cylinder 25 are perpendicular to each other. The movable end of the second propulsion cylinder 27 is connected to an extension mounting bracket 28. The mounting frame 28 has finger cylinders 29 at its bottom. Two push cylinders 27 can drive the two finger cylinders 29 to perform relative or opposite transmission. When the two finger cylinders 29 drive inwards, they can clamp the two sides of the film material. The push cylinder 25 drives the finger cylinders 29 and the film material clamped by the finger cylinders 29 to move away from the pressing mechanism 4. The push cylinder 25 pushes the transmission shaft 23, and the transmission shaft 23 rotates. The synchronous gear 26 drives the rack 24 relative to each other, realizing the synchronous transmission of the two racks 24. This maintains the accuracy of synchronous transmission, prevents the film material from wrinkling, and improves the coating effect. It also has the advantages of simple structure and high transmission synchronization rate.

[0034] In this embodiment, the sealing mechanism 5 includes four lifting cylinders 21 disposed on the second mounting frame 20 and an upper sealing frame 22 connected to the four lifting cylinders 21; the sealing mechanism 5 also includes a plurality of lifting cylinders 40 disposed around the air chamber mechanism, and the plurality of lifting cylinders 40 are connected to a lower sealing frame 41.

[0035] In this embodiment, the pressure mechanism 4 includes a second lifting cylinder 31 and a third lifting cylinder 32 mounted on the second mounting bracket 20. The bottom of the second lifting cylinder 31 is connected to a first pressing block 33, and the top of the third lifting cylinder 32 is connected to a second pressing block 34. The first pressing block 33 and the second pressing block 34 are arranged vertically, and the first pressing block 33 and the second pressing block 34 form a clamping structure.

[0036] In this embodiment, a heat insulation mechanism is also provided on the second mounting bracket 20. The heat insulation mechanism includes a transmission module and a heat insulation plate 35 connected to the transmission module. In this embodiment, since the transmission module is located at the bottom of the heat insulation plate 35, it is not shown in the figure. The transmission direction of the transmission module is the same as that of the feeding mechanism 3.

[0037] In this embodiment, the air chamber mechanism 8 includes an air chamber 36 and a vacuum adsorption module 37 connected to the air chamber 36. The shape of the air chamber 36 is adapted to the upper sealing film frame 22.

[0038] In this embodiment, a cutter assembly is also provided on the side of the air chamber 36. The cutter assembly includes a lifting cylinder 4 38 and a cutter 39 disposed on the top of the lifting cylinder 4 38, and the cutter assembly is located near the pressing module 4.

[0039] Working principle: The film feed rack 6 loads the roll film, and the product is placed in the positioning groove on the air chamber 36. The beginning end of the film extends between the first pressure block 33 and the second pressure block 34. The second lifting cylinder 31 and the third lifting cylinder 32 drive in opposite directions to achieve the positioning and pressing action of the film. The two finger cylinders 29 drive inwards and clamp the two sides of the film. The second lifting cylinder 31 and the third lifting cylinder 32 reset, and the first pushing cylinder 25 pushes the transmission shaft 23 for transmission. Shaft 23 rotates, and synchronous gear 26 drives relative transmission with rack 24. Feeding mechanism 3 drives the film to move, ensuring the film tension remains high during movement. The film material is between the lower sealing frame 41 and the upper sealing frame 22. Four lifting cylinders 1 21 drive the upper sealing frame 22 downward, and lifting cylinder 5 40 drive the lower sealing frame 41 upward. The upper sealing frame 22 and the lower sealing frame 40 press against each other and clamp the film, making the film material suspended. Then, lifting cylinder 2 31 and lifting cylinder 5 40... The three lowering cylinders 32 drive in opposite directions to achieve the positioning and pressing action of the film material. At the same time, the lifting cylinder 38 of the cutting assembly drives the cutter 39 to rise. The first lifting module 1 drives the heating module 2 to move downward, and the film material and the heating module 2 move closer to each other, so that the film material is at a certain distance from the product and is preheated. The second lifting module 7 drives the air chamber 36 to move upward, the upper sealing frame 22 presses against the lower sealing frame 41, and the movable end of the lifting cylinder 41 moves downward, then cuts the film material and covers the film material. The lower sealing frame 40 is attached to the top of the air chamber 36, forming a sealed space, bringing the product close to the bottom of the film material. The air chamber 36 is evacuated by the vacuum adsorption module 37, and the film material adheres to the inner wall of the product. The film is then applied to the product to reduce wrinkles. The lifting module 1 and lifting module 2 7 are reset. At the same time, the transmission module pushes the heat insulation plate 35, which isolates the heat between the heating module 2 and the pressing mechanism 4. Finally, the product is unloaded by automated equipment or manually.

[0040] Furthermore, the cylinder body of lifting cylinder 21 is larger than that of lifting cylinder 40, and the air inlet end of lifting cylinder 41 is connected to a pneumatic overflow valve 42. Therefore, when the second lifting module 7 drives the air chamber 36 to rise, lifting cylinder 40 overflows, the movable end of lifting cylinder 40 can move, and the upper sealing frame 22 and the lower sealing frame 41 always hold the film material.

[0041] Furthermore, the cutting assembly replaces the traditional heating wire cutting structure, preventing the exposure of high voltage electricity and further improving safety.

[0042] Furthermore, the second mounting bracket 20 is provided with two parallel slide rails 11, and the bottom of the toothed belt 24 is equipped with a slider 12 that is compatible with the slide rails 11. The slider 12 and the slide rails 11 are fitted together to improve the sliding smoothness of the rack 24 and the second mounting bracket 20, and improve the synchronization accuracy.

[0043] Furthermore, the air chamber 36 is provided with multiple positioning grooves for placing products, and the positioning grooves are provided with multiple micropores that communicate with the vacuum adsorption module 37.

[0044] Furthermore, a slide rail (not shown) is provided on the second mounting bracket 20, and a slider (not shown) adapted to the slide rail is installed at the bottom of the heat insulation plate 35. The slider and the slide rail are assembled together to improve the sliding smoothness of the heat insulation plate 35 and the second mounting bracket 20.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
