Description

Technical Field

[0001] This utility model relates to the field of aluminum foil lunch box pressing mold technology, and in particular to a two-layer rolled edge sealing pressing mold for sealing aluminum foil lunch boxes. Background Technology

[0002] Aluminum foil lunch boxes are disposable lunch boxes made of aluminum material, mainly used for food cooking, baking, freezing, preservation and takeout. They have a series of advantages such as being lightweight, having high barrier properties, being easy to recycle, and having good covering properties. They can better maintain the freshness of food and are in line with modern people's environmental protection and health concepts. In the production process of aluminum foil lunch boxes, aluminum foil needs to be stamped with molds to form the shape of the lunch box.

[0003] The existing pressing mold for sealing aluminum foil lunch boxes with two-layer rolled edges (announcement number: CN203900250U) uses a device that guides the lower pressing ring by matching the inner hole of the lower pressing ring with the outer shape of the lower die. The lower pressing ring has a rolling groove. The lower cylinder pushes the lower pressing ring to spring back through the lower cylinder push rod. The lower die is fixed on the lower die base, and the lower die base is fixed on the lower template. Although it can seal and press the rolled edges of the aluminum foil lunch box, during the feeding and unloading process, the operator usually needs to put their hands between the upper and lower molds to operate, which leads to low safety. In addition, after the upper and lower molds press the aluminum foil lunch box into shape, the formed lunch box is embedded in the interior of the lower mold, making it inconvenient for the operator to quickly remove the formed lunch box. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a two-layer rolled edge sealing mold for sealing aluminum foil lunch boxes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A two-layer rolled edge sealing mold for sealing aluminum foil lunch boxes includes a support base, a fixed frame, and a lower mold. The fixed frame is fixedly connected to the support base. A conveyor belt device is installed on the support base by fasteners. The lower mold is located on the conveyor belt device. A cylinder is fixedly installed on the inner wall of the fixed frame. A pressure plate is fixedly installed on the output end of the cylinder. An upper mold is fixedly installed at the bottom of the pressure plate. An electric push rod is fixedly installed on the outer side of the fixed frame. A rectangular block is fixedly installed on the output end of the electric push rod. A rectangular frame is fixedly installed on the side of the lower mold near the rectangular block. The rectangular block is fitted into the rectangular frame. A positioning pin is movably installed on the side of the lower mold near the rectangular block. A pusher plate is movably installed inside the lower mold. A telescopic tube is fixedly installed between the bottom of the pusher plate and the inner wall of the lower mold. A spring is sleeved on the telescopic tube.

[0007] As a further embodiment of this utility model, a guide post is fixedly provided on the inner side of the fixing frame, the pressure plate is slidably connected to the guide post, and the two ends of the second spring are respectively fixedly connected to the bottom of the pusher plate and the inner wall of the lower mold.

[0008] As a further embodiment of this utility model, a spring is sleeved on the guide post, and the two ends of the spring are respectively fixedly connected to the bottom of the pressure plate and the inner wall of the fixing frame. A sensor is provided on one side of the cylinder.

[0009] As a further embodiment of this utility model, the sensor is fixedly mounted on the mounting bracket, and a control console is fixedly provided on the side wall of the mounting bracket near the electric push rod.

[0010] As a further embodiment of this utility model, the rectangular blocks are symmetrically distributed on the lower mold, and the second spring and the telescopic tube are distributed at equal intervals at the bottom of the pusher plate.

[0011] As a further embodiment of this utility model, the positioning pin penetrates through the side wall of the lower mold and is embedded in the side wall of the pusher plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. During use, the operator first places the aluminum foil material into the lower mold, then starts the conveyor belt device via the control console. The conveyor belt transports the lower mold to the fixed frame. When the sensor detects the lower mold passing by, it transmits a signal to the control console. Upon receiving the signal, the control console opens the electric push rod, which pushes the rectangular block closer to the lower mold, allowing the rectangular block to interlock with the rectangular frame, thus fixing the lower mold below the upper mold. The control console then starts the cylinder, which pushes the pressure plate downward along the guide column. Simultaneously, the pressure plate deforms the spring, which provides a buffering effect, preventing excessive pressure and wear on the upper mold. The pressure plate moves the upper mold downward, pressing the aluminum foil material inside the lower mold. Once the aluminum foil lunch box is formed, the electric push rod extends and retracts to separate the rectangular block from the rectangular frame, releasing the lower mold from its positioning. The conveyor belt then transports the lower mold to one side for unloading. Simultaneously, the operator can continue feeding material on the other side of the conveyor belt, improving feeding efficiency and safety.

[0014] 2. After the aluminum foil lunch box is moved to one side by the lower mold, the staff can pull the positioning pin outward to separate the positioning pin from the lower mold and the pusher plate, release the limit on the pusher plate, and allow the compressed multiple springs to regain their elasticity. This causes the telescopic tube to extend and retract, pushing the pusher plate upward, thereby pushing the formed aluminum foil lunch box out. This assists the staff in quickly unloading the food and enhances convenience. Attached Figure Description

[0023] Reference Figures 1-4 A sealing aluminum foil lunch box two-layer rolled edge sealing pressing mold includes a support base 1, a fixed frame 2 and a lower mold 3. The fixed frame 2 is fixedly connected to the support base 1. A conveyor belt device 4 is installed on the support base 1 by fasteners. The lower mold 3 is located on the conveyor belt device 4. A cylinder 106 is fixedly installed on the inner wall of the fixed frame 2. A pressure plate 102 is fixedly installed on the output end of the cylinder 106. An upper mold 101 is fixedly installed at the bottom of the pressure plate 102. An electric push rod 201 is fixedly installed on the outer side of the fixed frame 2. A rectangular block 202 is fixedly installed at the output end of the electric push rod 201. A rectangular frame 6 is fixedly installed on the side of the lower mold 3 near the rectangular block 202. The rectangular block 202 is fitted into and connected to the rectangular frame 6. A positioning pin 5 is movably installed on the side of the lower mold 3 near the rectangular block 202. A pusher plate 203 is movably installed inside the lower mold 3. A telescopic tube 302 is fixedly installed between the bottom of the pusher plate 203 and the inner wall of the lower mold 3. A spring 301 is sleeved on the telescopic tube 302.

[0024] In use, the operator first places the aluminum foil material into the lower mold 3, and then starts the conveyor belt device 4 through the control console 303. The lower mold 3 is transported to the fixed frame 2 by the conveyor belt on the conveyor belt device 4. When the sensor 105 senses the passage of the lower mold 3, it transmits a signal to the control console 303. After receiving the signal, the control console 303 opens the electric push rod 201, which pushes the rectangular block 202 close to the lower mold 3, so that the rectangular block 202 is inserted into the rectangular frame 6, thereby fixing the lower mold 3 below the upper mold 101. The cylinder 106 is then started again through the control console 303, which pushes the pressure plate 102 along the guide. The column 104 moves downward, while the pressure plate 102 compresses the spring 103, which provides a buffer to prevent excessive pressure from causing wear on the upper mold 101. The pressure plate 102 drives the upper mold 101 to move downward, so that the upper mold 101 presses the aluminum foil material inside the lower mold 3. After the aluminum foil lunch box is formed, the electric push rod 201 extends and retracts to separate the rectangular block 202 from the rectangular frame 6, releasing the positioning of the lower mold 3. The conveyor belt device 4 then works to transport the lower mold 3 to one side for unloading. At the same time, the staff can continue to feed materials on the other side of the conveyor belt device 4, which improves feeding efficiency and safety.

[0025] In this embodiment, a guide post 104 is fixedly installed on the inner side of the fixing frame 2, and the pressure plate 102 is slidably connected to the guide post 104. The two ends of the spring 2 301 are respectively fixedly connected to the bottom of the pusher plate 203 and the inner wall of the lower mold 3.

[0026] In use, after the aluminum foil lunch box is moved to one side by the lower mold 3, the staff can pull the positioning pin 5 outward to separate the positioning pin 5 from the lower mold 3 and the pusher plate 203, release the limit on the pusher plate 203, and allow the compressed multiple sets of springs 301 to regain their elasticity, which drives the telescopic tube 302 to extend and retract, pushing the pusher plate 203 upward. Thus, the pusher plate 203 moves the formed aluminum foil lunch box out, assisting the staff in quickly unloading the material and enhancing convenience.

[0027] In this embodiment, a spring 103 is sleeved on the guide post 104. The two ends of the spring 103 are respectively fixedly connected to the bottom of the pressure plate 102 and the inner wall of the fixing frame 2. A sensor 105 is provided on one side of the cylinder 106.

[0028] In use, the conveyor belt device 4 mainly consists of components such as a drive unit, rollers and conveyor belt. The lower mold 3 is transported to one side for unloading through the conveyor belt device 4. At the same time, the operator can place another set of lower mold 3 on one side of the conveyor belt device 4 for loading, thereby improving work efficiency.

[0029] In this embodiment, the sensor 105 is fixedly mounted on the mounting bracket 2, and the mounting bracket 2 is fixedly mounted on the side wall near the electric push rod 201 with a control console 303.

[0030] In use, the rectangular block 202 is pushed close to the lower mold 3 by the electric push rod 201, so that the rectangular block 202 is inserted into the rectangular frame 6, thereby fixing the lower mold 3 below the upper mold 101 for precise stamping.

[0031] In this embodiment, rectangular blocks 202 are symmetrically distributed on the lower mold 3, and springs 301 and telescopic tubes 302 are evenly distributed at the bottom of the pusher plate 203.

[0032] In use, multiple sets of springs 301 and telescopic tubes 302 are provided at the bottom of the pusher plate 203. When the positioning pin 5 is pulled to separate from the lower mold 3 and the pusher plate 203, the limit on the pusher plate 203 can be released, allowing the multiple sets of compressed springs 301 to regain their elasticity, thereby causing the pusher plate 203 to move the formed aluminum foil lunch box out.

[0033] In this embodiment, the positioning pin 5 penetrates through the side wall of the lower mold 3 and is embedded in the side wall of the pusher plate 203.

[0034] When in use, the cylinder 106 is model MDBB32-50Z-M9BW, and the electric push rod 201 is model JC35FA2.

[0035] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: The operator can first place the aluminum foil raw material into the lower mold 3, and then start the conveyor belt device 4 through the control console 303. The lower mold 3 is transported to the fixed frame 2 via the conveyor belt on the conveyor belt device 4. When the sensor 105 senses the passage of the lower mold 3, it transmits a signal to the control console 303. After receiving the signal, the control console 303 opens the electric push rod 201, causing the electric push rod 201 to push the rectangular block 202 closer to the lower mold 3, so that the rectangular block 202 is inserted into the rectangular frame 6, thereby fixing the lower mold 3 below the upper mold 101. The control console 303 then starts the cylinder 106, causing the cylinder 106 to push the pressure plate 102 downwards along the guide post 104. At the same time, the pressure plate 102 compresses the spring 103, which provides a buffering effect, preventing excessive pressure from causing wear on the upper mold 101. Plate 102 drives the upper mold 101 to move downward, so that the upper mold 101 presses the aluminum foil material inside the lower mold 3. After the aluminum foil lunch box is pressed into shape, the electric push rod 201 extends and retracts to separate the rectangular block 202 from the rectangular frame 6, releasing the positioning of the lower mold 3. The conveyor belt device 4 then works to transport the lower mold 3 to one side for unloading. At the same time, the staff can continue to feed materials on the other side of the conveyor belt device 4, which improves feeding efficiency and safety. After the formed aluminum foil lunch box is moved to one side by the lower mold 3, the staff can pull the positioning pin 5 outward to separate the positioning pin 5 from the lower mold 3 and the push plate 203, releasing the limit on the push plate 203. This allows the compressed multiple sets of springs 301 to regain their elasticity, driving the telescopic tube 302 to extend and retract, pushing the push plate 203 upward. Thus, the push plate 203 moves the formed aluminum foil lunch box out, assisting the staff in quickly unloading and improving convenience.
