Description

Technical Field

[0001] This invention relates to the field of aluminum foil bag production technology, specifically to a composite device for aluminum foil bag production. Background Technology

[0002] Aluminum foil bags are bags made of composite materials such as aluminum foil and plastic film, commonly used for packaging food, medicine, cosmetics, and other items. Aluminum foil bags offer advantages such as moisture resistance, oxidation prevention, UV protection, and moisture retention, effectively protecting the quality and freshness of the contents. The production of aluminum foil bags typically involves a lamination process, combining aluminum foil with materials such as plastic film. This is because aluminum foil alone suffers from poor moisture retention, insufficient rigidity, and high cost. The lamination production process for aluminum foil bags utilizes equipment such as coating machines, laminating machines, and pressing machines.

[0003] In related technologies, Chinese Patent Publication No. CN216832728U discloses a composite device for producing aluminum foil bags, comprising a mounting box, an mounting frame installed inside the mounting box, an unwinding roller rotatably connected to the mounting frame, and an aluminum foil bag wound around the unwinding roller; an extrusion composite assembly installed inside the mounting box for extruding the aluminum foil bag; and a transmission port opened on the mounting box through which the aluminum foil bag passes. In use, the aluminum foil bag is passed between the extrusion composite assemblies, which are then driven to move closer together to extrude the aluminum foil bag. The extrusion composite assemblies are then driven to rotate, extruding and transmitting the aluminum foil bag. However, in the above technology, after the aluminum foil bag is transported, the unwinding roller needs to be disassembled and replaced. During the replacement process, the laminating device needs to be paused for a long time to control the extrusion laminating component to reset, then the unwinding roller is removed, a new unwinding roller with the aluminum foil bag wound on it is installed, the aluminum foil bag is passed through the extrusion laminating component again, and the extrusion laminating component is controlled to extrude the aluminum foil bag again. The replacement operation is cumbersome, prolongs the production laminating waiting time, and reduces production efficiency. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one objective of the present invention is to provide a laminating device for aluminum foil bag production, which, through the cooperation of an automatic transfer assembly, multiple unwinding rollers, and an extrusion assembly, achieves efficient and continuous lamination of aluminum foil and plastic film, thereby improving production efficiency.

[0005] The first aspect of the present invention provides a composite apparatus for producing aluminum foil bags, comprising:

[0006] A base, on which a support frame and a composite box are provided. The support frame includes two vertical support plates installed in parallel on the base. The composite box is installed on the base and located on one side of the support frame. The interior of the composite box forms an installation cavity. The side of the installation cavity near the support frame is provided with a feed port, and the side away from the support frame is provided with a discharge port.

[0007] Two unwinding mechanisms are respectively installed between two vertical support plates. One unwinding mechanism is used to unwind plastic film, and the other unwinding mechanism is used to unwind aluminum foil. Each unwinding mechanism includes multiple unwinding rollers and an automatic rotation assembly. The multiple unwinding rollers are respectively connected to the automatic rotation assembly. The automatic rotation assembly is used to automatically rotate the unwound roller to a non-working position after the material on one of the unwinding rollers has been unwound, and to rotate the next unwound roller to a working position to achieve continuous production.

[0008] The extrusion assembly includes two first extrusion rollers symmetrically arranged in the mounting cavity of the composite box along the vertical direction. An extrusion composite area for aluminum foil and plastic film to pass through is formed between the two first extrusion rollers, thereby achieving tight bonding between the aluminum foil and the plastic film.

[0023] A connecting block is installed at one end of the rotating rod and is adapted to a sliding groove in the baffle; when the rotating rod rotates, the connecting block slides in the sliding groove, thereby driving the baffle to rotate;

[0024] A connecting groove is formed on the side wall of the slot and is adapted to the baffle. The connecting groove allows the baffle to rotate within it, thereby sealing or opening the notch.

[0025] In a first aspect of the invention, as a preferred embodiment, the extrusion assembly further includes two second extrusion rollers symmetrically arranged in the mounting cavity of the composite box along the vertical direction, forming an extrusion composite area for aluminum foil and plastic film to pass through between the two second extrusion rollers, and the two second extrusion rollers are located to the right of the two first extrusion rollers.

[0026] In a first aspect of the present invention, as a preferred embodiment, threaded rods are respectively provided through one end of the two first extrusion rollers and the two second extrusion rollers, and an adjusting motor is installed at the upper end of the threaded rods. Guide rods are respectively provided through the other end of the two first extrusion rollers and the two second extrusion rollers.

[0027] In a first aspect of the present invention, as a preferred embodiment, two mounting housings are respectively provided on both sides of the composite box, the threaded rod is installed in the mounting housing on one side, the adjusting motor is installed on the mounting housing on that side, and the guide rod is installed in the mounting housing on the other side.

[0028] In a first aspect of the invention, as a preferred embodiment, a winding assembly is further included, the winding assembly being used to wind up the composited material.

[0029] In a first aspect of the invention, as a preferred embodiment, two anti-deviation components are symmetrically arranged on the side of the support frame away from the composite box, and a driving component is installed between the two anti-deviation components to adjust the distance between the two anti-deviation components to prevent the unwinding roller from deviating.

[0030] In a first aspect of the present invention, as a preferred embodiment, the anti-deviation component includes upper and lower symmetrically arranged limiting plates, a connecting plate is installed on one end of the two limiting plates relatively close to each other, and a connecting frame is installed between the upper and lower connecting plates by screws;

[0031] The driving component includes a lead screw and a third motor installed at one end thereon. A connecting rod is provided on one side of the lead screw, and both the lead screw and the connecting rod pass through two connecting frames.

[0032] The support frame is equipped with a fixed plate on the side away from the composite box. The lead screw and connecting rod are both installed between the two fixed plates. The third motor is installed on the outside of the fixed plate on one side by screws. The lead screw is a bidirectional lead screw.

[0033] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0034] 1. In this invention, the plastic film and aluminum foil are unwound separately via unwinding mechanisms. Each unwinding mechanism is equipped with multiple unwinding rollers. When the material on one unwinding roller is exhausted, the automatic indexing component automatically rotates the next unwinding roller, now filled with material, to the working position, ensuring the continuity of the unwinding process. The plastic film and aluminum foil released from the unwinding mechanism are guided into the mounting cavity of the laminating box. In the laminating box, two first extrusion rollers extrude and laminate the two materials at a constant speed and pressure. In the extrusion lamination area, the aluminum foil and plastic film are tightly bonded under pressure, forming a uniform composite material. The laminated material is discharged from the outlet of the laminating box and can then be collected or directly entered into the next production stage. Thus, this embodiment, through the cooperation of the automatic indexing component, multiple unwinding rollers, and extrusion component, achieves efficient and continuous lamination of aluminum foil and plastic film, improving production efficiency.

[0035] 2. The automatic indexing assembly of this invention includes a rotary drive motor, a mounting plate, a turntable, and multiple connecting rollers. Initially, the connecting rollers are detachably mounted between the mounting plate and the turntable, arranged in a circular array around the turntable. Each connecting roller is fitted with an unwinding roller wrapped with aluminum foil or plastic film. When the material on a particular unwinding roller is unwound, the rotary drive motor receives a signal and begins operation. The output shaft of the rotary drive motor is connected to the center of the turntable, driving the turntable to rotate. Since the mounting plate and the turntable are rotatably mounted on a vertical support plate, the rotation of the turntable causes the mounting plate and connecting rollers to rotate together. When the next unused unwinding roller rotates to the working position, the rotary drive motor stops operating, completing the automatic indexing. When all the material on the unwinding rollers is used up, a new unwinding roller can be replaced by disassembling the connecting rollers. After replacement, the connecting rollers are reinstalled, and the positions of the turntable and mounting plate are adjusted so that the new unwinding roller is in the working position. In this way, the automatic rotation component drives the turntable and mounting plate to rotate via a rotary drive motor, enabling rapid and automatic replacement of the unwinding rollers, thus ensuring the continuity and efficiency of the aluminum foil bag production process. This design not only simplifies the operation process but also improves production efficiency and product quality.

[0036] 3. The connecting assembly of the present invention also includes a sealing assembly. Under normal operating conditions, the sealing assembly is in a closed position, completely sealing the notch and ensuring that the connecting roller will not accidentally detach through the notch during unwinding. This state ensures the stability and safety of the unwinding process and prevents production accidents caused by the connecting roller detaching. When it is necessary to replace the connecting roller, the sealing assembly moves to the open position, exposing the notch, allowing the connecting roller to be removed or inserted through the notch. This state facilitates the replacement of the connecting roller by the operator, improving work efficiency. By flexibly controlling the opening and closing of the notch, the sealing assembly ensures both the safety and stability of the unwinding process and improves the convenience of connecting roller replacement.

[0037] 4. The sealing assembly of this invention includes a baffle, a rotating rod, a connecting block, and a connecting groove. The baffle can be rotated with a simple rotation operation, thereby quickly releasing the restriction on the connecting roller and facilitating the replacement of the winding roller. This design allows operators to flexibly control the rotation angle of the baffle according to actual conditions, thus adapting to different operational needs.

[0038] 5. This invention utilizes a combination of a limiting plate, a connecting plate, a connecting frame, a lead screw, a connecting rod, and a third motor. When the third motor drives the lead screw to rotate, the two connecting frames (and their limiting plates) move simultaneously towards the center or simultaneously outward, thereby adjusting the distance between the two anti-deviation components. The third motor drives the bidirectional lead screw to rotate, thus adjusting the distance between the two anti-deviation components (i.e., the two sets of limiting plates). In this way, regardless of the size of the unwinding roller, its stability and deviation can be ensured by adjusting the distance between these two anti-deviation components.

[0055] Please refer to Figure 1-7 As shown, this embodiment provides a composite device for producing aluminum foil bags, including a base 10, two unwinding mechanisms 20 and an extrusion assembly 30;

[0056] Specifically, a support frame 11 and a composite box 12 are provided on the base 10. The support frame 11 includes two vertical support plates 111 that are installed in parallel on the base 10. The composite box 12 is installed on the base 10 and located on one side of the support frame 11. The interior of the composite box 12 forms an installation cavity 121. An inlet 122 is provided on the side of the installation cavity 121 near the support frame 11, and an outlet 123 is provided on the side away from the support frame 11.

[0057] Specifically, two unwinding mechanisms 20 are respectively installed between two vertical support plates 111. One unwinding mechanism 20 is used to unwind plastic film, and the other unwinding mechanism 20 is used to unwind aluminum foil. The unwinding mechanism 20 includes multiple unwinding rollers 21 and an automatic rotation component 22. The multiple unwinding rollers 21 are respectively connected to the automatic rotation component 22. The automatic rotation component 22 is used to automatically rotate the unwinding roller 21 to a non-working position after the material on one of the unwinding rollers 21 has been unwound, and to rotate the next unwound roller 21 to a working position to achieve continuous production.

[0058] Specifically, the extrusion assembly 30 includes two first extrusion rollers 31 symmetrically arranged in the mounting cavity 121 of the composite box 12 along the vertical direction. An extrusion composite area for aluminum foil and plastic film to pass through is formed between the two first extrusion rollers 31, so as to achieve tight bonding between aluminum foil and plastic film.

[0059] Based on the above structure, the plastic film and aluminum foil are unwound by the unwinding mechanism 20. Each unwinding mechanism 20 is equipped with multiple unwinding rollers 21. When the material of one unwinding roller 21 is exhausted, the automatic rotation component 22 automatically rotates the next unwinding roller 21 filled with material to the working position, ensuring the continuity of the unwinding process. The plastic film and aluminum foil released from the unwinding mechanism 20 are guided into the mounting cavity 121 of the laminating box 12. In the laminating box 12, two first extrusion rollers 31 extrude and laminate the two materials at a constant speed and pressure. In the extrusion lamination area, the aluminum foil and plastic film are tightly bonded under pressure to form a uniform composite material. The laminated material is discharged from the discharge port 123 of the laminating box 12 and can then be collected or directly enter the next production stage. Thus, this embodiment achieves efficient and continuous lamination of aluminum foil and plastic film through the cooperation between the automatic rotation component 22, multiple unwinding rollers 21, and extrusion component 30, improving production efficiency.

[0060] In a preferred embodiment of the present invention, the automatic rotation assembly 22 includes a rotary drive motor 221, a mounting plate 222, a turntable 223, and a plurality of connecting rollers 224;

[0061] Mounting plate 222 and turntable 223 are rotatably mounted on two vertical support plates 111, respectively;

[0062] Multiple connecting rollers 224 are detachably connected between the mounting plate 222 and the turntable 223, and the multiple connecting rollers 224 are arranged in a ring around the turntable 223.

[0063] Each connecting roller 224 is used to mount an unwinding roller 21 wrapped with aluminum foil or plastic film;

[0064] The rotary drive motor 221 is mounted on the vertical support plate 111, and the output shaft of the rotary drive motor 221 is connected to the middle of the turntable 223.

[0065] Based on the above structure, in the initial state, multiple connecting rollers 224 are detachably installed between the mounting plate 222 and the turntable 223, arranged in a circular array around the turntable 223. Each connecting roller 224 is fitted with an unwinding roller 21 wrapped with aluminum foil or plastic film. When the material on a certain unwinding roller 21 is unwound, the rotary drive motor 221 receives a signal and starts working. The output shaft of the rotary drive motor 221 is connected to the center of the turntable 223, driving the turntable 223 to rotate. Since the mounting plate 222 and the turntable 223 are rotatably mounted on the vertical support plate 111, the rotation of the turntable 223 will drive the mounting plate 222 and the connecting rollers 224 to rotate together. When the next unused unwinding roller 21 rotates to the working position, the rotary drive motor 221 stops working, completing the automatic rotation. When the material on all the unwinding rollers 21 is used up, a new unwinding roller 21 can be replaced by disassembling the connecting rollers 224. After replacement, the connecting roller 224 is reinstalled, and the positions of the turntable 223 and mounting plate 222 are adjusted so that the new unwinding roller 21 is in the working position. In this way, the automatic indexing assembly 22 drives the turntable 223 and mounting plate 222 to rotate via the rotary drive motor 221, achieving rapid and automatic replacement of the unwinding roller 21, thus ensuring the continuity and efficiency of the aluminum foil bag production process. This design not only simplifies the operation process but also improves production efficiency and product quality.

[0066] In a preferred embodiment of the present invention, the unwinding mechanism 20 further includes multiple sets of connecting components 23, the connecting components 23 including a movable plate 231 and an electric telescopic rod 232;

[0067] One end of the movable plate 231 is hinged to the turntable 223, and the other end extends out of the turntable 223 to form a connecting part. A slot 2311 is provided on the connecting part, and a notch 2312 communicating with the slot 2311 is provided on one side of the connecting part.

[0068] One end of the electric telescopic rod 232 is mounted on the turntable 223, and its telescopic rod is connected to the movable plate 231;

[0069] When the telescopic rod of the electric telescopic rod 232 is in the extended state, the connecting roller 224 is inserted into the slot 2311 of the connecting part. When the electric telescopic rod 232 is in the retracted state, the connecting roller 224 can disengage from the slot 2311 through the notch 2312.

[0070] Based on the above structure, when it is necessary to connect the connecting roller 224 to the unwinding mechanism 20, first align the connecting roller 224 with the slot 2311 on the connecting part of the movable plate 231. Next, control the extension of the electric telescopic rod 232, pushing the movable plate 231 to rotate around the hinge point until the connecting roller 224 is fully inserted into the slot 2311. When the electric telescopic rod 232 reaches the preset extension state, the connecting roller 224 is securely connected to the unwinding mechanism 20, ready for unwinding. When it is necessary to replace the connecting roller 224, control the retraction of the electric telescopic rod 232. As the electric telescopic rod 232 retracts, the movable plate 231 rotates in the opposite direction around the hinge point, gradually disengaging the connection between the slot 2311 and the connecting roller 224. When the electric telescopic rod 232 is fully retracted, the connecting roller 224 can easily disengage from the slot 2311 through the notch 2312, completing the disconnection process. The connecting assembly 23, through the cooperation of the electric telescopic rod 232 and the movable plate 231, achieves a stable connection and quick replacement of the connecting roller 224. This design not only improves production efficiency but also reduces the complexity and error rate of manual operation, providing a strong guarantee for the continuity and stability of aluminum foil bag production.

[0071] In a preferred embodiment of the present invention, the number of connecting components 23 is three sets, which are arranged in a ring around the circumference of the turntable 223. The design of the three sets of connecting components 23 arranged in a ring around the circumference of the turntable 223 not only improves the stability and durability of the turntable 223 structure, but also optimizes the stress distribution, simplifies the manufacturing and maintenance process, and provides a strong guarantee for the efficient and safe operation of the turntable 223.

[0072] In a preferred embodiment of the present invention, the connecting component 23 further includes a blocking component 24, which is mounted on the connecting portion of the movable plate 231 and is used to block or open the notch 2312.

[0073] Based on the above structure, under normal operating conditions, the sealing component 24 is in the closed position, completely sealing the notch 2312 to ensure that the connecting roller 224 will not accidentally detach through the notch 2312 during unwinding. This state ensures the stability and safety of the unwinding process, preventing production accidents caused by the connecting roller 224 detaching. When it is necessary to replace the connecting roller 224, the sealing component 24 moves to the open position, exposing the notch 2312, allowing the connecting roller 224 to be removed or inserted through the notch 2312. This state facilitates the replacement of the connecting roller 224 by operators, improving work efficiency. By flexibly controlling the opening and closing of the notch 2312, the sealing component 24 ensures both the safety and stability of the unwinding process and improves the convenience of replacing the connecting roller 224.

[0074] In a preferred embodiment of the invention, the blocking assembly 24 includes:

[0075] Baffle 241 is arc-shaped. One end of baffle 241 is rotatably mounted on movable plate 231. A sliding groove 2411 is provided in baffle 241.

[0076] Rotating rod 242 is installed on one side of baffle 241 and extends to the outside of movable plate 231. Rotating rod 242 is threadedly connected to movable plate 231, so that rotating rod 242 can rotate and move on movable plate 231.

[0077] A connecting block 243 is installed at one end of the rotating rod 242 and is adapted to the sliding groove 2411 in the baffle 241. When the rotating rod 242 rotates, the connecting block 243 slides in the sliding groove 2411, thereby driving the baffle 241 to rotate.

[0078] The connecting groove 244 is formed on the side wall of the slot 2311 and is adapted to the baffle 241. The connecting groove 244 allows the baffle 241 to rotate within it, thereby blocking or opening the notch 2312.

[0079] Based on the above structure, the baffle 241 is in its initial position, sealing the notch 2312 to ensure the stability and safety of the connecting roller 224 during unwinding. The connecting roller 224 is securely limited by the cooperation of the slot 2311 and the connecting groove 244. When unwinding is complete and the winding roller needs to be replaced, the operator begins disassembly. The operator rotates the rotating rod 242 outwards. Since the rotating rod 242 is threadedly connected to the movable plate 231, this rotation causes the rotating rod 242 to move outwards along the threaded path. As the rotating rod 242 rotates outwards, the connecting block 243 also moves. The connecting block 243 slides in the groove 2411 opened in the baffle 241. This sliding action is transmitted to the baffle 241, causing the baffle 241 to rotate within the connecting groove 244. When the baffle 241 rotates to a certain angle, it will no longer limit the connecting roller 224, meaning the baffle 241 no longer seals the notch 2312. At this point, one end of the connecting roller 224 is released from the slot 2311, allowing the operator to easily disassemble the unwinding winding roller. In the initial state, the baffle 241 effectively seals the notch 2312, ensuring that the connecting roller 224 will not fall off during unwinding, thus improving operational safety. The baffle 241 can be rotated with a simple rotation, quickly releasing the restriction on the connecting roller 224 and facilitating the replacement of the winding roller. This design allows the operator to flexibly control the rotation angle of the baffle 241 according to actual conditions, thereby adapting to different operational needs.

[0080] In a preferred embodiment of the present invention, the extrusion assembly 30 further includes two second extrusion rollers 32 symmetrically arranged in the mounting cavity 121 of the composite box 12 along the vertical direction, and an extrusion composite area for aluminum foil and plastic film to pass through is formed between the two second extrusion rollers 32, and the two second extrusion rollers 32 are located to the right of the two first extrusion rollers 31.

[0081] This layout facilitates a continuous production line, allowing the aluminum foil and plastic film to smoothly enter the second extrusion roller 32 for further lamination after initial processing by the first extrusion roller 31. This two-stage extrusion process more effectively ensures a tight bond between the aluminum foil and plastic film, improving the lamination quality.

[0082] In a preferred embodiment of the present invention, threaded rods 33 are respectively provided through one end of the two first extrusion rollers 31 and the two second extrusion rollers 32, and an adjusting motor 34 is installed on the upper end of the threaded rods 33. Guide rods 35 are respectively provided through the other end of the two first extrusion rollers 31 and the two second extrusion rollers 32.

[0083] Based on the thickness and material properties of the aluminum foil and plastic film to be laminated, the position of the extrusion rollers is adjusted by adjusting motor 34 to ensure a suitable gap between the rollers. The aluminum foil and plastic film are fed into the mounting cavity 121 of the laminating box 12 and gradually approach the extrusion rollers. When the aluminum foil and plastic film enter the extrusion lamination area, they are compressed by the extrusion rollers, achieving a tight bond. During production, if it is necessary to adjust the lamination thickness or adapt to different materials, the adjusting motor 34 can be restarted, and the position of the extrusion rollers can be fine-tuned by rotating the threaded rod 33. After adjusting the position of the extrusion rollers, continuous and efficient lamination production can be carried out. In this embodiment, by adding components such as the threaded rod 33, adjusting motor 34, and guide rod 35, the extrusion assembly 30 not only improves the lamination quality but also achieves precise adjustment of the extrusion roller position and efficient production.

[0084] In a preferred embodiment of the present invention, two mounting housings 124 are respectively provided on both sides of the composite box 12. The threaded rod 33 is installed in the mounting housing 124 on one side, the adjusting motor 34 is installed on the mounting housing 124 on that side, and the guide rod 35 is installed in the mounting housing 124 on the other side. These housings are robustly designed to not only protect the internal adjusting mechanism but also ensure the precise installation and stable operation of each component.

[0085] In a preferred embodiment of the invention, a winding assembly is further included, which is used to wind up the composite material.

[0086] In a preferred embodiment of the present invention, two anti-deviation components are symmetrically arranged on the side of the support frame away from the composite box, and a driving component is installed between the two anti-deviation components to adjust the distance between the two anti-deviation components to prevent the unwinding roller from deviating.

[0087] Specifically, the anti-deviation component includes symmetrically arranged upper and lower limit plates 41, and a connecting plate 42 is installed on one end of the two limit plates 41 relatively close to each other. A connecting bracket 43 is installed between the upper and lower connecting plates 42 by screws.

[0088] The driving component includes a lead screw 44 and a third motor 46 installed at one end thereon. A connecting rod 45 is provided on one side of the lead screw 44. Both the lead screw 44 and the connecting rod 45 pass through two connecting frames 43.

[0089] The support frame is equipped with a fixing plate 47 on the side away from the composite box. The lead screw 44 and the connecting rod 45 are both installed between the two fixing plates 47. The third motor 46 is installed on the outside of the fixing plate 47 on one side by screws. The lead screw 44 is a bidirectional lead screw 44.

[0090] Based on the above structure, the limiting plate 41, connecting plate 42, connecting frame 43, lead screw 44, connecting rod 45, and third motor 46 work together. When the third motor 46 drives the lead screw 44 to rotate, the two connecting frames 43 (and the limiting plates 41 on them) will move simultaneously towards the center or simultaneously outward, thereby adjusting the distance between the two anti-deviation components. The third motor 46 drives the bidirectional lead screw 44 to rotate, thereby adjusting the distance between the two anti-deviation components (i.e., the two sets of limiting plates 41). In this way, regardless of the size of the unwinding roller, its stability and deviation can be ensured by adjusting the distance between these two anti-deviation components.

[0091] Although only certain components and embodiments of this application have been illustrated and described, many modifications and alterations will be apparent to those skilled in the art without actually departing from the scope and spirit of the claims, such as variations in the size, dimensions, structure, shape and proportion of the various elements, installation arrangement, material use, color, orientation, etc.

[0092] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
