A forming apparatus for processing aluminum foil containers

Abstract

This utility model discloses a forming device for processing aluminum foil containers, comprising: a first forming mechanism, including a support and a processing table below the inner side of the support; a hydraulic pusher cylinder is fixedly installed on the top of the support, and the output end of the hydraulic pusher cylinder has an installation groove; and a lifting component for lifting the aluminum foil container after forming is installed on the top of the processing table. In the second forming mechanism of this utility model, a synchronous plate, under the pressure of a slope-shaped push rod, pushes a semi-circular seat to move directly below the bottom of the sleeve, forming a circular structure. This allows the first arc groove at the bottom of the sleeve to mate with the second arc groove at the top of the semi-circular seat. When the synchronous plate and the sleeve move relative to each other, the edge of the aluminum foil container opening can be precisely bent and rolled, enabling the rolling process to be completed synchronously during the aluminum foil container forming process without additional steps, greatly improving production efficiency and eliminating the risk of accidental damage.

Description

Technical Field

[0001] This utility model relates to the field of forming equipment technology, and in particular to a forming device for processing aluminum foil containers. Background Technology

[0002] Aluminum foil containers are a lightweight, durable, and reusable packaging material, typically made of thin aluminum sheets. They possess excellent thermal conductivity and are moisture-proof and oxidation-resistant, making them widely used for food storage, cooking, and microwave heating. Their environmentally friendly properties also make them a viable alternative to single-use plastic containers, offering convenience and reducing resource waste.

[0003] During the aluminum foil container processing, the container opening is thin, which not only makes it easy to scratch during use or handling, but also poses a significant safety hazard to operators' fingers when manually handling and transferring the container after forming, as these sharp edges can easily cause injury. Although existing technology uses an external edge curler to address this issue, this method usually requires two steps to complete the edge curling, which not only increases the number of steps and consumes manpower and time, but also directly affects the overall production efficiency. At the same time, the risk of accidental injury during manual handling still exists, so improvements are needed. Utility Model Content

[0004] One objective of this invention is to provide a forming device for aluminum foil container processing. This invention addresses the issue raised in the background that during the forming process of aluminum foil containers, the container opening, being a thin sheet, is prone to scratches during use or handling. Furthermore, when manually handling and transferring the container after forming, the sharp edges can easily injure the operator's fingers, posing a significant safety hazard. Although existing technologies use external edge curlers to address this problem, this method typically requires two steps to complete the edge curling, increasing the number of steps, consuming manpower and time, and directly impacting overall production efficiency. Additionally, the risk of injury during manual handling remains.

[0005] A forming apparatus for processing aluminum foil containers according to an embodiment of the present invention includes:

[0006] The first forming mechanism includes a support and a processing table below the inner side of the support. A hydraulic pusher cylinder is fixedly installed on the top of the support. An installation groove is opened at the output end of the hydraulic pusher cylinder. A lifting component for lifting the aluminum foil container after forming is installed on the top of the processing table.

[0007] The second forming mechanism is installed on top of the processing table in the first forming mechanism and is used to limit the position of the aluminum foil container during the stamping process.

[0008] An edge-rolling mechanism is installed on the outside of the hydraulic cylinder output end in the first forming mechanism to simultaneously roll the edge during the forming of the aluminum foil container. The edge-rolling mechanism includes two sleeves sleeved on the outside of the hydraulic cylinder output end. The sleeves are connected to the hydraulic cylinder output end through an installation component to achieve quick assembly and disassembly. In the second forming mechanism, a semi-circular seat is fixedly provided at one end of the synchronous plate corresponding to the forming mold. A first arc groove is opened at the bottom of the sleeve, and a second arc groove is opened at one end of the top of the semi-circular seat corresponding to the first arc groove, for bending the edge of the aluminum foil container opening.

[0009] The pushing mechanism, installed at the output end of the hydraulic cylinder in the first forming mechanism, is used to push out the formed aluminum foil container.

[0010] Preferably, the lifting assembly includes a support platform fixed to the top of the processing table, and a buffer platform is movably mounted on the top of the support platform via a first spring.

[0011] Preferably, the second forming mechanism includes a synchronization plate fixed to the output end of the hydraulic push cylinder and a centering seat movable on both sides of the top of the processing table. A slope-shaped push rod is symmetrically fixed on one side of the bottom of the synchronization plate. The centering seat and the processing table are both provided with a sliding groove adapted to the slope-shaped push rod.

[0012] Preferably, the mounting assembly includes a docking post fixed to one end of one of the sleeves and a docking hole opened at one end of the other sleeve. The docking post and the docking hole are adapted to each other and are engaged. A mounting seat is fixedly provided on the top of the sleeve, and the mounting seat is sleeved in the mounting groove on the outside of the hydraulic cylinder output end.

[0013] Preferably, magnetic stones are fixedly provided inside the docking hole and at the end of the docking post for magnetic installation.

[0014] Preferably, the pushing mechanism includes an L-shaped rack fixed to the outside of the output end of the hydraulic push cylinder and a guide frame fixed to one side of the processing table. A gear is rotatably arranged inside the guide frame via a rotating shaft. The gear and the L-shaped rack are meshed and driven. A T-shaped rack that meshes and drives the gear is movably arranged at the center of the guide frame. An arc-shaped feeding plate is fixedly arranged at the front end of the T-shaped rack.

[0015] Preferably, a second spring is installed between the tail end of the T-shaped toothed rod and the guide frame.

[0016] The beneficial effects of this utility model are:

[0017] This invention effectively avoids the problem of time-consuming, labor-intensive, and inefficient edge-rolling operations caused by the two-step edge-rolling process, thanks to its specially designed edge-rolling mechanism. During use, the two sleeves are engaged with the connecting posts and holes in the mounting assembly, and magnetic stones are fixed inside and at the ends, facilitating quick installation and disassembly of the edge-rolling mechanism. When the hydraulic cylinder operates, it drives the second forming mechanism and the edge-rolling mechanism to move downwards synchronously. The synchronous plate in the second forming mechanism, pressed down by the slope-shaped push rod, pushes the semi-circular seat to directly below the bottom of the sleeve, forming a circular structure. This allows the first arc groove at the bottom of the sleeve to mate with the second arc groove at the top of the semi-circular seat. During the relative movement of the synchronous plate and the sleeve, the edge of the aluminum foil container can be precisely bent and rolled, enabling the edge-rolling process to be completed synchronously during the aluminum foil container forming process, eliminating the need for additional steps, greatly improving production efficiency, and eliminating the risk of accidental damage.

[0018] This invention effectively avoids the problem of accidental injury caused by manual handling of containers after molding through a designed pushing mechanism. After the hydraulic pusher cylinder completes the molding and edge rolling of the aluminum foil container, the L-shaped toothed rod moves upward with the output end of the hydraulic pusher cylinder, driving the gear meshing with it to rotate. The gear then drives the T-shaped toothed rod to move in the opposite direction, and the arc-shaped feeding plate fixed at the front end of the T-shaped toothed rod moves forward accordingly, pushing the molded aluminum foil container off the processing table. When the hydraulic pusher cylinder pushes down, the T-shaped toothed rod will drive the arc-shaped feeding plate back to the starting position. Therefore, this mechanism avoids the safety hazard of fingers being scratched by the edge of the container when manually handling it, and also improves production efficiency and product quality.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0026] refer to Figure 1-4 A forming apparatus for processing aluminum foil containers, comprising:

[0027] The first forming mechanism 1 includes a support 101 and a processing table 102 located below the inner side of the support 101. A hydraulic pusher 103 is fixedly installed on the top of the support 101. An installation groove 108 is opened at the output end of the hydraulic pusher 103. A lifting component for lifting the aluminum foil container after forming is installed on the top of the processing table 102.

[0028] The second forming mechanism 2 is installed on the top of the processing table 102 in the first forming mechanism 1. It is used to limit the position of the aluminum foil container during the stamping process. The second forming mechanism 2 includes a synchronization plate 201 fixed to the output end of the hydraulic push cylinder 103 and a centering seat 202 movable on both sides of the top of the processing table 102. A slope-shaped push rod 203 is symmetrically fixed on one side of the bottom of the synchronization plate 201. The centering seat 202 and the processing table 102 are both provided with a sliding groove 204 that matches the slope-shaped push rod 203. When the hydraulic push cylinder 103 works, it drives the synchronization plate 201 to move downward. The slope-shaped push rod 203 will enter the sliding groove 204 and push the centering seat 202 to move towards the center, thereby accurately limiting the position of the aluminum foil material during the stamping process and ensuring the accuracy and consistency of the forming.

[0029] The edge-rolling mechanism 3 is installed on the outside of the output end of the hydraulic pusher cylinder 103 in the first forming mechanism 1. It is used to simultaneously roll the edge during the forming of the aluminum foil container. The edge-rolling mechanism 3 includes two sleeves 301 that are sleeved on the outside of the output end of the hydraulic pusher cylinder 103. The sleeves 301 are connected to the output end of the hydraulic pusher cylinder 103 through a mounting assembly for quick assembly and disassembly. The mounting assembly includes a docking post 304 fixed to one end of one sleeve 301 and a docking hole 303 opened at one end of the other sleeve 301. The docking post 304 and the docking hole 303 are adapted to each other and are engaged. A mounting seat 302 is fixedly provided on the top of the sleeve 301. 302 is fitted into the mounting groove 108 on the outside of the output end of the hydraulic push cylinder 103. In the second forming mechanism 2, the synchronous plate 201 is fixedly provided with a semi-circular seat 307 at one end of the forming mold 104. The bottom of the sleeve 301 is provided with a first arc groove 306, and the top of the semi-circular seat 307 is provided with a second arc groove 308 at one end of the first arc groove 306. It is used to bend the edge of the aluminum foil container. When in use, the two sleeves are engaged with the docking post and docking hole in the mounting assembly, and magnetic stones are fixed inside and at the ends, which facilitates the quick installation and disassembly of the edge rolling mechanism. When the hydraulic push cylinder works, it drives the second forming mechanism and the edge rolling mechanism to move downward synchronously. The synchronous plate in the second forming mechanism pushes the semi-circular seat to move directly below the bottom of the sleeve under the pressure of the slope-shaped push rod, forming a circular structure. This allows the first arc groove at the bottom of the sleeve to match the second arc groove at the top of the semi-circular seat. When the synchronous plate and the sleeve move relative to each other, the edge of the aluminum foil container can be bent and rolled precisely, so that the rolling process can be completed synchronously during the forming of the aluminum foil container without additional steps, which greatly improves production efficiency.

[0030] The pushing mechanism 4, installed at the output end of the hydraulic cylinder 103 in the first forming mechanism 1, is used to push out the formed aluminum foil container. The pushing mechanism 4 includes an L-shaped rack 401 fixed to the outside of the output end of the hydraulic cylinder 103, and a guide frame 402 fixed to one side of the processing table 102. A gear 403 is rotatably arranged inside the guide frame 402 via a rotating shaft 404. The gear 403 and the L-shaped rack 401 are meshed and driven. A T-shaped rack 405 is movably arranged at the center of the guide frame 402 and meshes with the gear 403. An arc-shaped feeding plate 407 is fixedly installed at the front end of the rack 405. After the hydraulic push cylinder completes the forming and edge rolling of the aluminum foil container, the L-shaped rack moves upward together with the output end of the hydraulic push cylinder, driving the gear meshing with it to rotate. The gear then drives the T-shaped rack to move in the opposite direction, and the arc-shaped feeding plate fixed at the front end of the T-shaped rack moves forward accordingly, pushing the formed aluminum foil container out of the processing table. When the hydraulic push cylinder pushes down, the T-shaped rack will drive the arc-shaped feeding plate back to the starting position. Therefore, this mechanism avoids the safety hazard of fingers being cut by the edge of the container when manually handling it.

[0031] Example 1: The lifting assembly includes a support platform 105 fixed to the top of the processing table 102. After the aluminum foil container is initially formed on the processing table 102, it will naturally fall onto the buffer platform 107. The buffer platform 107 is movably set on the top of the support platform 105 by a first spring 106. The first spring 106 can buffer the impact force of the container falling and prevent it from being deformed or damaged due to excessive impact force.

[0032] Example 2: Magnets 305 are fixedly installed inside the docking hole 303 and at the end of the docking post 304 for magnetic installation, so as to achieve a quick, stable and detachable connection. A second spring 406 is installed between the tail end of the T-shaped toothed rod 405 and the guide frame 402. After the gear 403 drives the T-shaped toothed rod 405 and the arc-shaped feeding plate 407 at its front end to complete the action of pushing out the forming container, the second spring 406 will automatically pull the T-shaped toothed rod 405 back to the initial position.

[0033] Working principle: First, the aluminum foil material is placed on the processing table 102 of the first forming mechanism 1. The hydraulic push cylinder 103 is activated, driving the synchronous plate 201 and the second forming mechanism 2 to move downward. The slope-shaped push rod 203 at the bottom of the synchronous plate 201 enters the centering seat 202 and the slide groove 204 of the processing table 102, pushing the centering seat 202 to move towards the center, precisely limiting the position of the aluminum foil material. At the same time, the sleeve 301 of the edge rolling mechanism 3 moves downward synchronously outside the output end of the hydraulic push cylinder 103. The first arc groove 306 at the bottom of the sleeve 301 is aligned with the second arc groove 308 at the top of the semi-circular seat 307 at one end of the synchronous plate 201, forming a circular structure. When the forming mold 104 contacts the aluminum foil material, it continues to press down to complete the stamping. At this time, the first arc groove 306 at the bottom of the sleeve 301 of the edge-rolling mechanism 3 and the second arc groove 308 at the top of the semi-circular seat 307 are tightly engaged to bend and roll the edge of the aluminum foil container opening, achieving synchronous edge rolling. After forming, the hydraulic push cylinder 103 drives the synchronous plate 201 and the second forming mechanism 2 to lift upward. At this time, the formed aluminum foil container will fall onto the buffer platform 107 of the lifting assembly. Then, the output end of the hydraulic push cylinder 103 drives the L-shaped gear 401 to move upward, and drives the gear 403 to rotate through meshing transmission. This drives the T-shaped rack 405 and its front-end arc-shaped feeding plate 407 to move forward, pushing the formed container off the processing table 102. When the hydraulic push cylinder 103 presses down again, the L-shaped rack 401 moves in the opposite direction, and the gear 403 drives the T-shaped rack 405 to retract. The second spring 406 assists in resetting it to its initial position, preparing for the next pushing cycle. Throughout the process, the edge-rolling mechanism 3 achieves quick assembly and disassembly and stable connection through the engagement of the docking post 304 and the docking hole 303, as well as the magnetic installation of the magnetic stone 305. The automatic pushing and resetting function of the pushing mechanism 4 avoids the risk of fingers being scratched by the edge of the container when handling it manually, improving production efficiency and safety.
