Description

Technical Field

[0001] This utility model relates to the field of chemically formed aluminum foil processing technology, specifically to a chemically formed aluminum foil splicing device. Background Technology

[0002] Chemically formed aluminum foil is the process of processing aluminum into thin sheets. It mainly includes melting aluminum blocks, casting and rolling them into sheets, annealing to improve flexibility, and finally cutting or rolling them into finished products. Chemically formed aluminum foil is widely used in food packaging, pharmaceuticals, and other daily necessities, and is popular due to its excellent barrier properties and lightweight characteristics.

[0003] In the production process of aluminum foil, it is often necessary to change the rolls of raw materials. This mainly involves connecting a roll of raw materials that is about to finish production with a new roll of raw materials. The traditional method is to use a foil-joining hammer to strike the surfaces of the two raw materials that need to be joined during the roll change, so that the two aluminum foils are riveted together. Usually, this foil-joining method is done manually by repeatedly striking the foil with a foil-joining hammer. This is not only time-consuming and labor-intensive, but also the hammering points cannot evenly cover the entire connection area, resulting in inconsistent strength at the joint between the two aluminum foils and poor connection effect. Utility Model Content

[0004] The purpose of this invention is to provide a foil forming and splicing device for aluminum foil, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A foil forming and splicing device for aluminum foil includes a workbench. A vertical frame is fixed on one side of the workbench. A drive mechanism is provided on the frame. A pair of vertically distributed mounting seats are installed on the side of the frame through the drive mechanism. The two drive mechanisms are used to drive the two mounting seats to move closer or further apart. Pressure rollers are installed on the sides of the two mounting seats. Riveting plates are fixed at corresponding positions on the two pressure rollers. Several protrusions extending along the length of the riveting plate are fixed at intervals on the upper riveting plate. Several grooves for the protrusions to match and fit into the lower riveting plate are arranged at intervals.

[0007] As can be seen, the two mounting seats are driven to move closer to each other by the working of the drive mechanism, which in turn drives the two rivet plates to move closer to each other. By utilizing the ductility of the formed aluminum foil, the two formed aluminum foils are pressed into the groove by the convex ridge, thus achieving foil bonding. The automation level is high, the pressing points and force distribution are uniform and consistent, and the foil bonding quality is high.

[0008] The protruding ridges are used to press the joint of the two formed aluminum foils into the groove. Multiple protruding ridges and grooves are provided, which can greatly increase the riveting area of ​​the two formed aluminum foils, ensure high structural strength at the joint, and effectively improve the firmness of the foil joint.

[0009] Furthermore, both pressure rollers are rotatable and adjustable, and pressure plates are fixed at corresponding positions on the two pressure rollers to flatten the aluminum foil splicing area.

[0010] Furthermore, each pressure roller is rotatably mounted on a mounting base, and each mounting base is equipped with a second drive device for driving the pressure roller to rotate and adjust.

[0011] Furthermore, both second drive devices are drive motors, which are fixed on the mounting base, and their output shafts are fixedly connected to the shaft ends of the corresponding pressure rollers.

[0012] Furthermore, the drive mechanism includes a bidirectional threaded rod, a first drive device, and a nut seat. The side of the stand is provided with a vertically extending drive groove. The bidirectional threaded rod is rotatably installed in the drive groove. The first drive device is arranged on the top of the stand and is used to drive the bidirectional threaded rod to rotate and adjust. The two nut seats are respectively limited and slidably installed in the drive groove and are respectively threadedly matched and fitted on the bidirectional threaded rod. The mounting seat is correspondingly installed on the side of the nut seat.

[0013] Furthermore, the first driving device uses a drive motor, which is fixed to the top of the stand, and its output shaft is fixedly connected to the top of the bidirectional threaded rod.

[0014] Furthermore, mounting plates are fixed to the sides of both nut seats, and vertical through holes are provided on both mounting plates. Sliding rods are slidably inserted through both sliding holes. The two mounting seats are respectively fixed to the ends of the two sliding rods that are close to each other. Springs are fitted on both sliding rods. One end of the spring is fixed to the surface of the mounting plate, and the other end of the spring is fixed to the surface of the mounting seat.

[0015] Furthermore, the cross-section of the convex ridge is triangular, and the cross-section of the groove is a V-shape that matches the convex ridge.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0017] This invention uses a drive mechanism to drive two mounting bases closer together, which in turn drives two rivet plates closer together. Utilizing the ductility of the formed aluminum foil, the protruding ridges press the joint of the two formed aluminum foils into the groove to achieve foil bonding. It has a high degree of automation, uniform and consistent distribution of pressing points and force, and high foil bonding quality.

[0018] This invention utilizes protruding ridges to press the joint of two formed aluminum foils into a groove. Multiple protruding ridges and grooves are provided, which can greatly increase the riveting area of ​​the two formed aluminum foils, ensure high structural strength at the joint, and effectively improve the firmness of the foil joint.

[0019] This invention uses the rotation adjustment of two pressure rollers to switch the two pressure plates to the working position. Then, the drive mechanism drives the two pressure rollers to move closer to each other. The two pressure plates can flatten the riveting joint. On the one hand, they can press the undulations of the riveting joint firmly and further enhance the strength of the connection. On the other hand, they can flatten the riveting joint, improve the flatness of the connection, and ensure the appearance quality of the foil riveting. Attached Figure Description

[0025] Please see Figures 1-4 This utility model provides a forming aluminum foil splicing device. The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0027] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0028] This foil splicing equipment includes a workbench 1, with a vertically fixed frame 2 on one side above the workbench 1. A drive mechanism 3 is provided on the frame 2. A pair of vertically distributed mounting seats 4 are installed on the side of the frame 2 through the drive mechanism 3. The two drive mechanisms 3 are used to drive the two mounting seats 4 to move closer or further apart. Pressure rollers 5 are installed on the sides of the two mounting seats 4. Riveting plates 6 are fixed at corresponding positions on the two pressure rollers 5. Several protrusions 61 extending along the length of the riveting plate 6 are fixed at intervals on the upper riveting plate 6. Several grooves 62 are arranged at intervals on the lower riveting plate 6 for the protrusions 61 to match and fit into one by one.

[0029] The two formed aluminum foils to be connected are overlapped and placed between the two rivet plates 6. The driving mechanism 3 drives the two mounting seats 4 to move closer to each other, which in turn drives the two rivet plates 6 to move closer to each other. Utilizing the ductility of the formed aluminum foil, the joint of the two formed aluminum foils is pressed into the groove 62 by the protrusion 61, so as to realize the foil pressing and joining. The degree of automation is high, the pressing point and force distribution are uniform and consistent, and the foil joining quality is high.

[0030] The two formed aluminum foils are pressed into the groove 62 by using the protruding ribs 61. Multiple protruding ribs 61 and grooves 62 are provided, which can greatly increase the riveting area of ​​the two formed aluminum foils, ensure the structural strength of the connection, and effectively improve the firmness of the foil connection.

[0031] In addition, the cross-section of the protruding rib 61 is triangular, and the cross-section of the groove 62 is V-shaped to match the protruding rib 61. The design of the triangular cross-section of the protruding rib 61 and the V-shaped cross-section of the groove 62 makes it easy for the protruding rib 61 and the riveting joint to come out of the groove 62 when separated, and the structural layout is reasonable.

[0032] Specifically, both pressure rollers 5 can be rotated and adjusted, and pressure plates 7 are fixed at corresponding positions on the two pressure rollers 5 to flatten the aluminum foil splicing area.

[0033] After the two aluminum foils are riveted together using the convex rib 61 and the groove 62, the driving mechanism 3 drives the two pressure rollers 5 to move away. Then, the two pressure rollers 5 are rotated and adjusted to switch the two pressure plates 7 to the working position. Subsequently, the driving mechanism 3 drives the two pressure rollers 5 to move closer to each other. The two pressure plates 7 can flatten the riveted area. On the one hand, they flatten the uneven parts of the riveted area, further enhancing the firmness of the connection. On the other hand, they flatten the riveted area, improve the flatness of the connection, and ensure the appearance quality of the riveted aluminum foil.

[0034] Specifically, each pressure roller 5 is rotatably mounted on the mounting base 4, and each mounting base 4 is equipped with a second drive device 41 for driving the pressure roller 5 to rotate and adjust. Both second drive devices 41 are drive motors, which are fixed on the mounting base 4 and their output shafts are fixedly connected to the shaft end of the corresponding pressure roller 5. When the drive motors work, their output shafts can drive the pressure roller 5 to rotate, thereby providing a drive for switching the positions of the rivet plate 6 and the protrusion 61.

[0035] Specifically, the drive mechanism 3 includes a bidirectional threaded rod 31, a first drive device 32, and a nut seat 33. The side of the stand 2 is provided with a vertically extending drive groove 301. The bidirectional threaded rod 31 is rotatably installed in the drive groove 301. The first drive device 32 is arranged on the top of the stand 2 and is used to drive the bidirectional threaded rod 31 to rotate and adjust. The two nut seats 33 are respectively limited and slidably installed in the drive groove 301 and are respectively threadedly matched and fitted on the bidirectional threaded rod 31. The mounting seat 4 is correspondingly installed on the side of the nut seat 33. The first drive device 32 is a drive motor. The drive motor is fixed on the top of the stand 2, and its output shaft is fixedly connected to the top end of the bidirectional threaded rod 31.

[0036] The drive motor operates, and its output shaft drives the bidirectional threaded rod 31 to rotate. The rotating bidirectional threaded rod 31 can drive the two nut seats 33 to move closer or further apart in the drive groove 301, providing a drive for riveting and flattening actions.

[0037] Specifically, mounting plates 8 are fixed to the sides of both nut seats 33. Both mounting plates 8 are provided with vertically penetrating sliding holes 81. Sliding rods 82 are slidably inserted into both sliding holes 81. The two mounting seats 4 are respectively fixed to the ends of the two sliding rods 82 that are close to each other. Springs 83 are fitted on both sliding rods 82. One end of the spring 83 is fixed to the surface of the mounting plate 8, and the other end of the spring 83 is fixed to the surface of the mounting seat 4.

[0038] During the riveting or flattening process, if the pressure is excessive, the mounting base 4 pushes the slide bar 82 to move back, and the two springs 83 are compressed and stored, which plays a buffering and protective role for the aluminum foil and avoids damage to the aluminum foil caused by excessive pressure.

[0039] 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.
