Description

Technical Field

[0001] This invention relates to the field of packaging machine technology, and in particular to an automatic packaging machine for roll materials. Background Technology

[0002] In industrial production, after roll materials (such as fabric rolls) are wound and formed, they usually need to be wrapped with a protective film and the film is sealed and fixed before being unloaded from the packaging station to achieve protective functions such as dust prevention, moisture prevention, and scratch prevention, while facilitating subsequent storage and transportation.

[0003] Currently, the lamination and packaging of roll materials mostly adopts a semi-automatic or multi-stage independent operation method. First, the laminating machine wraps the film, then the film is cut and sealed manually or by special equipment, and finally the material is hoisted and unloaded. This multi-equipment, multi-station decentralized operation mode results in a large floor space, long material flow path, difficulty in coordinating production rhythm, unstable sealing quality, and complex unloading structure. Therefore, there is an urgent need for an automatic roll material packaging machine that integrates film laying, bundling, cutting, sealing, and unloading functions to simplify the structure and improve efficiency. Summary of the Invention

[0004] This invention discloses an automatic roll packaging machine, which mainly solves the problem that most existing roll packaging machines only have parts for coating and cutting the roll, and do not have integrated packaging that combines coating, cutting, sealing and unloading. This makes it inconvenient to operate in a centralized manner, resulting in a large floor area for the entire line and troublesome roll operation.

[0005] To achieve the aforementioned objective, the technical solution of the present invention is implemented as follows: The present invention provides an automatic roll packaging machine, including a frame, a strapping and film covering device on the frame, a film cutting device on one side of the strapping and film covering device and a material unloading device on the other side of the frame, a sealing device at the end of the strapping and film covering device, and a material pushing device below the strapping and film covering device. The bundling and film-coating device includes a bundling mechanism for driving the roll material to rotate and a film-releasing mechanism, wherein the film-releasing mechanism is used to release the roll film onto the surface of the roll material for winding. The film cutting device includes a film cutting mechanism for cutting the film after the film winding is completed; The sealing device includes a hot air mechanism and a film pressing mechanism symmetrically arranged at both ends of the binding mechanism. The hot air mechanism is used to heat the film at the end of the roll to make it melt, and the film pressing mechanism is used to press the melted film tightly to seal the roll. The pushing device includes a pushing component that is driven to rise and fall by a pushing drive mechanism. The pushing component is located below the binding mechanism. When the pushing drive mechanism drives the pushing component to rise, it pushes the sealed roll of material toward the unloading device. The unloading device is used to carry and transport the sealed roll material.

[0006] In one embodiment, the bundling mechanism includes a first bundling roller and a second bundling roller spaced apart, the first bundling roller and the second bundling roller being used to carry the roll material, the first bundling roller and the second bundling roller rotating in the same direction, and the film feeding mechanism includes a first film feeding roller and a second film feeding roller spaced apart and an air-expanding roller for placing the roll film, the first film feeding roller and the second film feeding roller rotating in opposite directions.

[0007] In one embodiment, a pressure plate is provided on the frame above the first and second film-laying rollers. A film support plate for carrying the end of the film and a material support plate for carrying the end of the roll are provided on the frame between the binding mechanism and the film-laying mechanism. There is a gap between the film support plate and the material support plate. The film-cutting mechanism is located above the gap between the film support plate and the material support plate.

[0008] In one embodiment, the film cutting device includes a movable film cutting base slidably connected to the frame. The movable film cutting base is driven by a movable film cutting drive mechanism to move along the length direction of the roll. A lifting film cutting base is slidably connected to the movable film cutting base. The lifting film cutting base is driven to move up and down by the lifting film cutting drive mechanism. The film cutting mechanism is disposed on the lifting film cutting base.

[0009] In one embodiment, the sealing device includes two movable sealing bases slidably connected to a frame. The movable sealing bases are driven by a movable sealing drive mechanism to move along the length of the roll. Each movable sealing base is slidably connected to a lifting sealing base, which is driven to rise and fall by a lifting sealing drive mechanism. The hot air mechanism is disposed on the movable sealing base at a corresponding position, and the film pressing mechanism is disposed on the lifting sealing base at a corresponding position.

[0010] In one embodiment, the hot air mechanism includes a fan and a heating duct, wherein the air outlet of the fan is connected to the air inlet of the heating duct, and the air outlet of the heating duct faces the end of the coil.

[0011] In one embodiment, the film pressing mechanism includes a film pressing plate driven by a film pressing drive member, which moves along the length of the roll material, and the film pressing plate is located at the end of the roll material carried by the binding mechanism.

[0012] In one embodiment, the pusher is provided with a plurality of pusher teeth, and the pusher teeth are provided with pusher inclined surfaces.

[0013] In one embodiment, the frame is provided with a blocking device on the side of the strapping and film-covering device away from the film-cutting device, the blocking device including a blocking block that is driven to rise and fall by a blocking drive mechanism.

[0014] In one embodiment, a guide platform is provided between the unloading device and the frame, and the height of the upper surface of the guide platform gradually decreases along the direction of the guide platform approaching the unloading device.

[0015] The advantages or beneficial effects of the above technical solution include at least the following: By setting up a bundling and film-coating device, a film-cutting device, a sealing device, and a pushing device on the frame, the bundling and film-releasing mechanisms of the bundling and film-coating device work together to coat the roll material. Then, the film-cutting mechanism of the film-cutting device cuts the coated film. The hot air mechanism of the sealing device heats and melts the film at the end of the roll material. The film-pressing mechanism then presses the heat-melted film to seal the roll. Finally, the pushing device pushes the sealed roll material to the unloading device, driven by the pushing drive mechanism. The unloading device then transports the finished product to the storage rack for subsequent packaging of the roll material. By integrating the bundling, film-cutting, sealing, pushing, and unloading devices, the entire process of roll material packaging is continuously automated. The layout is compact, the flow is efficient, and the packaging efficiency and quality are greatly improved. Attached Figure Description

[0024] See Figures 1 to 7 , Figure 15 An embodiment of the present invention provides an automatic roll packaging machine, including a frame 1, a bundling and film covering device 2 on the frame 1, a film cutting device 3 on one side of the bundling and film covering device 2 and a material unloading device 6 on the other side of the frame 1, a sealing device 4 at the end of the bundling and film covering device 2, and a material pushing device 5 below the bundling and film covering device 2. The bundling and coating device 2 includes a bundling mechanism 21 for driving the roll material to rotate and a film-releasing mechanism 22 for releasing the roll film onto the surface of the roll material for winding. The film cutting device 3 includes a film cutting mechanism 35 for cutting the film after the film winding is completed; The sealing device 4 includes a hot air mechanism 45 and a film pressing mechanism 46 symmetrically arranged at both ends of the bundling mechanism 21. The hot air mechanism 45 is used to heat the film at the end of the roll to make it melt, and the film pressing mechanism 46 is used to press the melted film to seal it. The pushing device 5 includes a pushing component 52 that is driven to rise and fall by the pushing drive mechanism 51. The pushing component 52 is located below the binding mechanism 21. When the pushing drive mechanism 51 drives the pushing component 52 to rise, it pushes the sealed roll of material toward the unloading device 6. The unloading device 6 is used to carry and transport the sealed roll material.

[0025] With the above structure, the bundling and film-coating device 2, film-cutting device 3, sealing device 4, and pushing device 5 are set on the frame 1. The bundling and film-coating device 2 uses the bundling mechanism 21 and the film-releasing mechanism 22 to coat the roll material. The film-cutting device 3 uses the film-cutting mechanism 35 to cut the coated film. The sealing device 4 uses the hot air mechanism 45 to heat-melt the film at the end of the roll material. The film-pressing mechanism 46 presses the heat-melted film to seal the roll material. Finally, the pushing device 5 uses the pushing drive mechanism 51 to drive the pushing component 52 to push the sealed roll material to the unloading device 6. The unloading device 6 then transports the finished product to the storage rack for subsequent packaging. By integrating the bundling, film-cutting, sealing, pushing, and unloading devices, the entire process of roll material packaging is continuously automated. The layout is compact and the flow is efficient, greatly improving packaging efficiency and quality.

[0026] In one embodiment, see Figure 2 , Figure 3 and Figure 15 To achieve the rotation of the roll material and the conveying of the film, the bundling mechanism 21 includes a first bundling roller 211 and a second bundling roller 212 spaced apart, which are used to support the roll material. The first bundling roller 211 and the second bundling roller 212 rotate in the same direction. The film feeding mechanism 22 includes a first film feeding roller 221 and a second film feeding roller 222 spaced apart, and an air-expanding roller 223 for placing the roll film. The first film feeding roller 221 and the second film feeding roller 222 rotate in opposite directions. Since the first bundling roller 211 and the second bundling roller 212 rotate in the same direction, this embodiment can use a combination of a motor, a transmission belt, and pulleys. Since the first film feeding roller 221 and the second film feeding roller 222 rotate in opposite directions, this embodiment can use two meshing gears, coupled with a motor driving one of the film feeding rollers.

[0027] A pressure plate 11 is provided on the frame 1 above the first film feeding roller 221 and the second film feeding roller 222. A film bearing plate 12 for carrying the end of the film and a material bearing plate 13 for carrying the end of the roll are provided on the frame 1 between the binding mechanism 21 and the film feeding mechanism 22. There is a gap between the film bearing plate 12 and the material bearing plate 13. The film cutting mechanism 35 is located above the gap between the film bearing plate 12 and the material bearing plate 13.

[0028] When wrapping the roll material with film, the rotation of the first binding roller 211 and the second binding roller 212 causes the roll material to rotate in the opposite direction, releasing the roll material onto the material support plate 13 and hanging it down into the gap between the film support plate 12 and the material support plate 13. Then, the rotation of the first film release roller 221 and the second film release roller 222 releases the film from the air expansion roller 223 onto the film support plate 12 until it is released onto the roll material. At this time, the first binding roller 211 and the second binding roller 212 drive the roll material to rotate in the forward direction, while simultaneously continuously releasing the film, so that the end of the film is wound into the roll material and wrapped around the roll material, thereby realizing the film wrapping operation of the roll material. In this process, various existing sensors, encoders, PLCs, or control circuits can be used to control whether the release of the roll material and the release of the film are in place, as well as the timing of the roll material winding. Therefore, the specific control method will not be described in detail here, as long as the function can be achieved.

[0029] In one embodiment, see Figure 4 To enable the film cutting operation of the film cutting mechanism 35, the film cutting device 3 includes a movable film cutting base 31 slidably connected to the frame 1. The movable film cutting base 31 is driven by a movable film cutting drive mechanism 32 to move along the length direction of the roll material. A lifting film cutting base 34 is slidably connected to the movable film cutting base 31. The lifting film cutting base 34 is driven to rise and fall by a lifting film cutting drive mechanism 33. The film cutting mechanism 35 is mounted on the lifting film cutting base 34. The movable film cutting base 31 and the frame 1, as well as the lifting film cutting base 34 and the movable film cutting base 31, can be slidably connected using slide rails and sliders. The film cutting mechanism 35 can utilize existing cutting equipment.

[0030] In this embodiment, the movable film-cutting drive mechanism 32 includes a film-cutting motor 321 mounted on the movable film-cutting base 31 and a film-cutting rack 322 mounted on the frame 1. The output end of the film-cutting motor 321 is provided with a film-cutting gear 323. The film-cutting rack 322 and the film-cutting gear 323 mesh with each other. When the film-cutting motor 321 drives the film-cutting gear 323, the movable film-cutting base 31 can be moved on the frame 1 through the cooperation of the film-cutting rack 322 and the film-cutting gear 323. The lifting film-cutting drive mechanism 33 can be a cylinder. During this process, various existing sensors, encoders, PLCs, or control circuits can be used to control whether the film-cutting mechanism 35 moves and is lifted to the correct position.

[0031] In one embodiment, see Figure 5 and Figure 6 To enable the movement and lifting / lowering of the hot air mechanism 45 and the film pressing mechanism 46, the sealing device 4 includes two movable sealing bases 41 slidably connected to the frame 1. The movable sealing bases 41 are driven by a movable sealing drive mechanism 42 to move along the length of the roll. Each movable sealing base 41 is slidably connected to a lifting sealing base 43, which is driven to rise and fall by a lifting sealing drive mechanism 44. The hot air mechanism 45 is positioned on the corresponding movable sealing base 41, and the film pressing mechanism 46 is positioned on the corresponding lifting sealing base 43. The frame 1 and the movable sealing bases 41, as well as the lifting sealing bases 43 and the movable sealing bases 41, can be slidably connected using slide rails and sliders. Both the movable sealing drive mechanism 42 and the lifting sealing drive mechanism 44 can be driven by cylinders or screw jacks. During this process, various existing sensors, encoders, PLCs, or control circuits can be used to control whether the hot air mechanism 45 and the film pressing mechanism 46 move and rise / fall into position.

[0032] The hot air mechanism 45 includes a fan 451 and a heating air duct 452. The air outlet of the fan 451 is connected to the air inlet of the heating air duct 452, and the air outlet of the heating air duct 452 faces the end of the coil. The heating air duct 452 can be an existing hot air generator, which can heat the airflow so that the blown air carries heat.

[0033] The film-pressing mechanism 46 includes a film-pressing plate 462 driven by a film-pressing drive 461, which moves the film-pressing plate 462 along the length of the roll. The film-pressing plate 462 is located at the end of the roll carried by the bundling mechanism 21. In practical applications, after the film at the end of the roll is melted by the hot air mechanism 45, the film-pressing plate 462 is moved to the end of the roll by the cooperation of the moving sealing drive mechanism 42 and the lifting sealing drive mechanism 44. Then, the film-pressing drive 461 drives the film-pressing plate 462 to press the melted film, thereby achieving the sealing operation.

[0034] In one embodiment, see Figure 2 , Figure 3 and Figure 7 To ensure that the pusher 52 can push the coiled material towards the unloading device 6 during its ascent, the pusher 52 is equipped with multiple pusher teeth 53, and each pusher tooth 53 has a pusher ramp 531. The pusher drive mechanism 51 can use a linear motor, cylinder, or other drive mechanism to drive the pusher 52. During this process, various existing sensors, encoders, PLCs, or control circuits can be used to control the lifting and lowering of the pusher 52 into position.

[0035] In one embodiment, see Figure 2 , Figure 3 and Figure 8 The frame 1 has an obstruction device 7 on the side of the bundling and film-coating device 2 away from the film-cutting device 3. The obstruction device 7 includes an obstruction block 72 that is driven to rise and fall by an obstruction drive mechanism 71. In practical applications, when the roll material is pushed from the fabric inspection machine onto the bundling mechanism 21, in order to prevent the roll material from detaching from the bundling mechanism 21 due to inertia during its rolling process, the obstruction drive mechanism 71 drives the obstruction block 72 to rise, thereby achieving the obstruction effect on the roll material and ensuring that the roll material remains on the bundling mechanism 21. The obstruction drive mechanism 71 can use a linear motor, cylinder, or other drive mechanism to drive the pusher 52. During this process, various existing sensors, encoders, PLCs, or control circuits can be used to control the rise and fall of the pusher 52 into position.

[0036] In one embodiment, see Figure 1 , Figure 2 , Figure 3 and Figure 15 In order to ensure that the packaged rolls can smoothly enter the unloading device 6, a guide platform 8 is provided between the unloading device 6 and the frame 1. The height of the upper surface of the guide platform 8 gradually decreases along the direction of the guide platform 8 towards the unloading device 6.

[0037] In one embodiment, see Figure 1 , Figures 9 to 15 The unloading device 6 includes symmetrically arranged unloading brackets 61. A load component 63 is slidably connected between the two unloading brackets 61 through a sliding component 62. A flipping component 65 is fixedly installed on the unloading bracket 61. The load assembly 63 includes a lifting crossbeam 631, a load member 632 rotatably connected to the lifting crossbeam 631, a load member 632 is provided on the load member 632 for carrying the coil material, a limit member 633 is provided on the side of the lifting crossbeam 631 facing the load member 632, and an unloading drive assembly 64 is provided on the unloading bracket 61 for driving the load assembly 63 to lift, so that the load assembly 63 has an unloading position and a loading position; When the load assembly 63 is in the unloading position, the flipping part 65 presses against the load part 632, forcing the load part 632 to rotate relative to the lifting crossbeam 631, so that the load part 632 abuts against the limiting part 633. When the load assembly 63 is in the load position, the load member 632 disengages from the flipping member 65, and the bottom surface of the load member 632 contacts the top surface of the lifting crossbeam 631.

[0038] To prevent the load component 632 from overturning when the coiled material falls into the bearing groove 6321, a limiting rod (not shown in the figure) can be installed between the two unloading brackets 61 when the load assembly 63 is in the load position. The limiting rod is used to support the side of the load component 632 that is about to overturn. To ensure that the load component 632 does not overturn during lifting and can return to its original position after unloading, the center of gravity of the load component 632 can be set on the non-overturning side.

[0039] Because a load assembly 63 and an unloading drive assembly 64 are arranged between the two unloading brackets 61, and with the cooperation of the tilting member 65, the unloading drive assembly 64 drives the load assembly 63 to lift upwards. When it reaches the unloading position, the tilting member 65 presses against the top of the load assembly 632, which forces the load assembly 632 to rotate. The bearing groove 6321 tilts and flips accordingly until it contacts the limiting member 633. At this time, the rolled material in the bearing groove 6321 automatically slides down under the action of gravity, completing the unloading. After that, the unloading drive... Component 64 drives the load component 63 to descend, and the load component 632 gradually detaches from the flipping component 65. Since the center of gravity of the load component 632 is set on the non-flipping side, under its own weight, the load component 632 rotates back in the opposite direction, and the bearing groove 6321 returns to the state of opening upward. The load component 632 automatically detaches from the limiting component 633 and returns to the load position, waiting for the next roll of material to be carried. In this process, the roll of material can be automatically unloaded and loaded into the roll rack, so as to reduce the intensity of manual labor and improve the unloading efficiency.

[0040] The sliding assembly 62 includes a slide rod 621 mounted on the unloading bracket 61 and a slide sleeve 622 mounted on the lifting crossbeam 631, with the slide sleeve 622 slidably connected to the slide rod 621. (See reference...) Figure 2 The slide rod 621 passes through the slide sleeve 622, thereby enabling the slide sleeve 622 to slide up and down along the slide rod 621.

[0041] The limiting member 633 includes a mounting part 6331 and a limiting part 6332 mounted on the lifting crossbeam 631. The limiting part 6332 is inclined away from the lifting crossbeam 631, so that there is an angle between the limiting part 6332 and the mounting part 6331. This angle can limit the flipping angle of the load member 632, so that when the load member 632 flips and detaches from the flipping member 65, it can automatically return to its original position by its own weight or center of gravity.

[0042] To ensure a stable rotatable connection between the load-bearing component 632 and the lifting crossbeam 631, the load-bearing component 632 is rotatably connected to the lifting crossbeam 631 via hinges 634. Multiple hinges 634 may be provided.

[0043] The unloading drive assembly 64 includes an unloading motor 641 and an output shaft 642 mounted on the unloading motor 641. Sprockets 643 are symmetrically arranged on the output shaft 642, and a chain 644 meshes with the sprockets 643. One end of the chain 644 is mounted on the lifting crossbeam 631. To ensure stable meshing of the chain 644 with the sprockets 643, a housing can be provided at the sprockets 643 for limiting movement, a counterweight can be provided at the other end of the chain 644, or a limiting sleeve can be provided at the other end to restrict the swing of the moving end of the chain 644 and prevent the chain 644 from skipping teeth.

[0044] The tilting component 65 includes a rotating shaft 651 mounted on the unloading bracket 61, and rollers 652 are provided on the rotating shaft 651. In practical applications, the rollers 652 reduce friction with the load component 632 and ensure smooth tilting of the load component 632.

[0045] To facilitate the installation of the rotating shaft 651 onto the unloading bracket 61, the rotating shaft 651 is installed onto the unloading bracket 61 via an L-shaped plate 653.
