Description

Technical Field

[0001] This utility model relates to a hot-pressing composite mechanism, specifically a hot-pressing composite mechanism for packaging films, belonging to the technical field of hot-pressing mechanisms for packaging films. Background Technology

[0002] Packaging film is a thin film used for packaging goods. It is widely used in the modern packaging industry, often in food packaging, pharmaceutical packaging, and other fields. The production of packaging film requires steps such as raw material preparation, extrusion plasticizing, molding, printing, and lamination. Among these steps, a thermoforming lamination mechanism is often used to combine two or more layers of packaging film together through the action of heat and pressure to form a composite packaging material with better performance. In order to make the equipment suitable for packaging films of different thicknesses, the height of the two ends of the pressure rollers usually needs to be adjusted one by one. During adjustment, the handwheels at the top of the two lead screws are turned in sequence. The lead screws drive the sliders on which the pressure rollers are mounted to slide, thereby driving the pressure rollers to move and adjusting the height of the two ends of the pressure rollers.

[0003] However, adjusting one by one makes the operation steps cumbersome, time-consuming and labor-intensive, and it is difficult to ensure that the two ends of the pressure roller can be adjusted precisely and synchronously. This may result in inconsistent heights at the two ends of the same pressure roller, leading to quality problems such as uneven pressure, wrinkles and weak bonding during the lamination process of the packaging film. Utility Model Content

[0004] The purpose of this utility model is to provide a packaging film hot-pressing lamination mechanism to solve the above problems. The mechanism uses a coarse adjustment structure to drive the support frame to move up and down, thereby initially adjusting the position of the pressure roller. Then, the meshing transmission of the first bevel gear and the second bevel gear drives the support frames at both ends of the same pressure roller to move up and down synchronously, thereby ensuring that the pressure roller always remains horizontal during the up and down adjustment process. This makes the operation time-saving and labor-saving, and also makes the lamination mechanism more uniform in hot-pressing the packaging film.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a packaging film hot-pressing composite mechanism, comprising a base plate, characterized in that: a support structure is provided on the base plate, the support structure includes a support seat, two support seats are fixedly connected to the base plate, an adjustment structure is fitted on the base plate, the adjustment structure includes a rotating shaft, two rotating shafts are rotatably connected inside the base plate, two first bevel gears are fixedly connected to each of the two rotating shafts, two support frames are slidably connected inside each of the two support seats, two lead screws are rotatably connected to the support seats, a second bevel gear is fixedly connected to the bottom of each of the two lead screws, the first bevel gears mesh with the second bevel gears, the lead screws are threadedly connected to the support frames, an mounting block is slidably connected to the support frame, a pressure roller is rotatably connected to the mounting block, the pressure roller is rotatably connected to the support seat, a second motor is fixedly connected to the side of the mounting block opposite to the pressure roller, the output shaft of the second motor is fixedly connected to the pressure roller, and a coarse adjustment structure is fitted on the support frame.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 As shown, a packaging film hot-pressing lamination mechanism includes a base plate 1, characterized in that: a support structure 2 is provided on the base plate 1, the support structure 2 includes a support base 201, two support bases 201 are fixedly connected to the base plate 1, an adjustment structure 3 is fitted on the base plate 1, the adjustment structure 3 includes a rotating shaft 301, two rotating shafts 301 are rotatably connected inside the base plate 1, two first bevel gears 302 are fixedly connected to each of the two rotating shafts 301, two support frames 305 are slidably connected inside each of the two support bases 201, two lead screws 304 are rotatably connected to the support bases 201, and second bevel gears 303 are fixedly connected to the bottom of each of the two lead screws 304, the first bevel gears 302 and the second bevel gears 303 are connected to each other. Gears 303 mesh with each other; lead screw 304 is threadedly connected to support frame 305; mounting block 306 is slidably connected to support frame 305; pressure roller 307 is rotatably connected to mounting block 306; pressure roller 307 is rotatably connected to support base 201; a second motor 308 is fixedly connected to the side of mounting block 306 opposite to pressure roller 307; the output shaft of the second motor 308 is fixedly connected to pressure roller 307; handwheels 309 are fixedly connected to the ends of both rotating shafts 301; a limit structure 4 is fitted on mounting block 306; the two rotating shafts 301 are symmetrically arranged; the cross-section of support frame 305 is "T" shaped; and a coarse adjustment structure 5 is fitted on support frame 305.

[0024] As a technical optimization of this utility model, two guide rods 310 are fixedly connected inside each of the two support seats 201, and the support frame 305 is slidably connected to the guide rods 310; the guide rods 310 have a guiding effect on the support seats 201, making the sliding of the support seats 201 more stable.

[0025] As a technical optimization of this utility model, two hot press rollers 202 are rotatably connected between the two support seats 201. A first motor 203 is fixedly connected inside one of the support seats 201, and the output shaft of the first motor 203 is fixedly connected to one of the hot press rollers 202. Two pulleys 204 are provided inside the other support seat 201, and pulleys 204 are fixedly connected to the ends of the two hot press rollers 202. A belt 205 is wound between the two pulleys 204. Different film materials to be laminated are respectively installed on corresponding unwinding devices. The two film materials are drawn out from the unwinding devices and guided by a series of guide rollers so that the film materials follow a predetermined path. The film is conveyed to the hot-pressing lamination zone, between the hot-pressing roller 202 and the pressure roller 307. At this time, the heating system starts to work, heating the film material and applying pressure to the film material through the pressure roller 307, thereby achieving lamination of the two film materials. Then, the first motor 203 is started, driving the hot-pressing roller 202, which is fixedly connected to the first motor 203, to rotate. The rotation of the hot-pressing roller 202 simultaneously drives the other hot-pressing roller 202 to rotate through the pulley 204 and the belt 205. Then, two second motors 308 are started, driving the two pressure rollers 307 to rotate respectively. Thus, the film material can be smoothly conveyed forward during the lamination process by the cooperation of the hot-pressing roller 202 and the pressure roller 307.

[0026] As a technical optimization of this utility model, the limiting structure 4 includes a guide strip 401, the guide strip 401 is fixedly connected to the mounting block 306, a limiting block 402 is slidably connected to the guide strip 401, the support frame 305 has multiple slots 404, the limiting block 402 engages with the slots 404, a spring 403 is fixedly connected between the limiting block 402 and the mounting block 306, the limiting block 402 has an "L" shaped cross-section, the multiple slots 404 are equidistantly arranged, and the coarse adjustment structure 5 includes two connecting rods 501, the two symmetrical limiting blocks 402... A connecting rod 501 is fixedly connected between the two support bases 201. The connecting rod 501 is slidably connected to the support base 201. Two connecting plates 502 are slidably connected between the two connecting rods 501. A hydraulic rod 503 is fixedly connected to the center of each of the two support bases 201. The telescopic end of the hydraulic rod 503 abuts against the connecting plate 502. The two connecting rods 501 are symmetrically arranged and have a "U"-shaped structure. Pushing the two connecting rods 501 towards the center of the support base 201 causes the connecting rods 501 to slide towards the center of the connecting plate 502. At the same time, the connecting rods 501 drive the two limiting blocks 402 to move towards the center. The internal sliding of mounting block 306 causes the limiting block 402 to no longer engage with the slot 404 on the support frame 305. At this time, the limiting block 402 retracts against the spring 403, thereby quickly releasing the limiting effect on mounting block 306. Then, the hydraulic rod 503 is activated, extending and contacting the connecting plate 502 upwards. Simultaneously, the connecting plate 502 drives the connecting rod 501 to slide upwards. The connecting rod 501 drives the pressure roller 307 to move upwards through the limiting block 402 and mounting block 306. When the pressure roller 307 is adjusted to the appropriate height, the two connecting rods 501 are released. At this time, the spring 403 resets and drives the limiting block 402 to engage with the slot 404 on the support frame 305. 04 engages, thus fixing the position of the pressure roller 307 and quickly increasing the distance between the pressure roller 307 and the hot pressure roller 202. When it is necessary to reduce the distance between the pressure roller 307 and the hot pressure roller 202, slide the two connecting rods 501 towards the middle of the connecting plate 502, and at the same time control the hydraulic rod 503 to retract. The pressure roller 307 moves downward under its own weight. When the pressure roller 307 moves to the appropriate position, release the connecting rods 501, so that the limiting block 402 engages with the slot 404, thereby fixing the position of the pressure roller 307. Through the cooperation of the limiting structure 4 and the coarse adjustment structure 5, the height of the pressure roller 307 can be quickly and initially adjusted.

[0027] In use, this invention first pushes the two connecting rods 501 towards the center of the support base 201, causing the connecting rods 501 to slide towards the center of the connecting plate 502. Simultaneously, the connecting rods 501 drive the two limiting blocks 402 to slide inwards towards the mounting block 306, preventing the limiting blocks 402 from engaging with the slots 404 on the support frame 305. At this point, the limiting blocks 402 retract against the spring 403, quickly releasing the limiting effect on the mounting block 306. Then, the hydraulic rod 503 is activated, extending and contacting the connecting plate 502 upwards. Simultaneously, the connecting plate 502 drives the connecting rods 501 to slide upwards. The connecting rod 501 drives the pressure roller 307 to move upward via the limiting block 402 and the mounting block 306. When the pressure roller 307 is adjusted to a suitable height, the two connecting rods 501 are released. At this time, the spring 403 resets and drives the limiting block 402 to engage with the slot 404, thereby fixing the position of the pressure roller 307 and quickly increasing the distance between the pressure roller 307 and the hot pressure roller 202. When it is necessary to reduce the distance between the pressure roller 307 and the hot pressure roller 202, the two connecting rods 501 slide towards the middle of the connecting plate 502, while controlling the hydraulic rod 503 to retract. Under its own gravity, the pressure roller 307 moves upward. The roller 307 moves downwards. Once the pressure roller 307 is in the appropriate position, the connecting rod 501 is released, causing the limiting block 402 to engage with the slot 404, thus fixing the position of the pressure roller 307. The cooperation between the limiting structure 4 and the coarse adjustment structure 5 allows for quick initial height adjustment of the pressure roller 307. When more precise height adjustment of the pressure roller 307 is required, the two handwheels 309 are rotated sequentially. The handwheels 309 drive the rotating shaft 301 to rotate, which in turn drives the two first bevel gears 302 to rotate. The two first bevel gears 302 mesh with and drive the two second bevel gears 303 to rotate. The rotation of wheel 303 simultaneously drives the lead screw 304 to rotate, thereby causing the lead screw 304 to drive the support frame 305 to move up and down. The movement of the support frame 305 simultaneously drives the pressure roller 307 to move up and down through the mounting block 306, thereby further finely adjusting the height of the pressure roller 307, making the hot-pressing and lamination of the packaging film uniform. Furthermore, the meshing transmission of the first bevel gear 302 and the second bevel gear 303 drives the support frames 305 at both ends of the same pressure roller 307 to move up and down synchronously, thereby ensuring that the pressure roller 307 remains horizontal during the up and down adjustment process. This saves time and effort and provides better adjustment results.Next, the different film materials to be laminated are installed on their respective unwinding devices. The two film materials are then drawn from the unwinding devices and guided by a series of guide rollers, transporting them along a predetermined path to the hot-pressing lamination area, specifically between the hot-pressing roller 202 and the pressure roller 307. At this point, the heating system begins operation, heating the film materials and applying pressure through the pressure roller 307, thus achieving lamination of the two film materials. Then, the first motor 203 is activated, driving the hot-pressing roller 202, which is fixedly connected to it, to rotate. Simultaneously, the rotation of this hot-pressing roller 202 drives the other hot-pressing roller 202 to rotate via pulley 204 and belt 205. Finally, two second motors 308 are activated, driving the two pressure rollers 307 to rotate respectively. Thus, the hot-pressing roller 202 and the pressure roller 307 work together to smoothly transport the film materials forward during the lamination process.
