Description

Technical Field

[0001] This utility model relates to the field of aluminum foil packaging technology, and in particular to a composite aluminum foil packaging box forming equipment. Background Technology

[0002] Aluminum foil is a hot stamping material made by directly rolling metallic aluminum into thin sheets. It is widely used in the production of disposable food packaging boxes. Whole sheets of aluminum foil can be formed into packaging boxes through stamping and cutting processes during processing.

[0003] Aluminum foil packaging boxes are usually cut off by a cutting blade after stamping. The waste generated during the cutting process is mostly treated by an adsorption dust removal mechanism. However, in actual processing, small wastes can easily fall into the inner cavity of the packaging box before it is demolded, either after they are generated or during the adsorption process. These wastes are difficult to detect in time, but they can affect the quality of the product, especially for packaging boxes that need to be sealed later. Utility Model Content

[0004] This utility model aims to provide a composite aluminum foil packaging box forming equipment to solve the problems mentioned in the background art. The solution has a simple structure and reasonable design. It integrates stamping and cutting functions into the upper mold assembly. The cutting area is surrounded by a sealed groove to form a closed area. Before the cutting blade finishes cutting and before the module leaves the mold cavity, the waste debris in the sealed groove is adsorbed by an adsorption mechanism. The waste debris is removed as soon as it is generated, eliminating the possibility of waste debris entering the aluminum foil packaging box, ensuring product quality and improving processing efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A composite aluminum foil packaging box forming device includes a base, an upper mold assembly, and a hydraulic cylinder. The top of the base has a mold cavity and a cutting groove, with the cutting groove surrounding the outside of the mold cavity. The upper mold assembly includes a module that matches the mold cavity. An mounting block is connected to the upper part of the outer end of the module. A sealing groove is formed around the module at the inner end of the mounting block. A knife holder is provided in the inner cavity of the sealing groove. A knife holder that works with the cutting groove is connected to the bottom end of the knife holder. Multiple connecting posts are connected to the top of the knife holder. The connecting posts pass through the mounting block and extend to the upper side of the mounting block. A limit block is connected to the output end of the hydraulic cylinder. All of the multiple connecting posts are connected to the limit block. A connecting pipe is connected to the outer end of the mounting block, with one end of the connecting pipe extending into the inner cavity of the sealing groove.

[0007] Preferably, the bottom end of the limiting block is connected to a limiting post, and the limiting post and the mounting block are slidably connected.

[0008] Preferably, a spring is sleeved on the outer end of the limiting post, and the two ends of the spring are respectively connected to the limiting block and the mounting block.

[0009] Preferably, the sealing groove is located directly above the cutting groove.

[0010] Preferably, a rubber pad is connected to the edge of the bottom end of the mounting block, and the rubber pad is arranged around the sealing groove.

[0011] The beneficial effects of this technical solution compared to existing technologies are as follows:

[0012] This solution features a simple structure and reasonable design, integrating stamping and cutting functions onto the upper mold assembly. A sealed groove surrounds the cutting area, and an adsorption mechanism adsorbs waste debris from the sealed groove before the cutting blade finishes cutting and the module leaves the mold cavity. This process removes waste debris as soon as it is generated, preventing it from entering the aluminum foil packaging box, ensuring product quality, and improving processing efficiency.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0018] like Figure 1-3The composite aluminum foil packaging box forming equipment shown includes a base 1, an upper mold assembly 2, and a hydraulic cylinder 3. The base 1 has a mold cavity 10 and a cutting groove 11 at its top, with the cutting groove 11 surrounding the outside of the mold cavity 10. The upper mold assembly 2 includes a module 21 that matches the mold cavity 10. A mounting block 22 is connected to the upper part of the outer end of the module 21. A sealing groove 23 surrounding the module 21 is formed at the inner end of the mounting block 22. A tool holder 5 is arranged inside the sealing groove 23. A tool holder 5 that mates with the cutting groove 11 is connected to the bottom end of the tool holder 5, and a tool holder 5 that cooperates with the cutting groove 11 is connected to the top end of the tool holder 5. Multiple connecting posts 7 pass through the mounting block 22 and extend to the upper side of the mounting block 22. The output end of the hydraulic cylinder 3 is connected to the limit block 4. All connecting posts 7 are connected to the limit block 4. The outer end of the mounting block 22 is connected to the connecting pipe 24. One end of the connecting pipe 24 extends into the inner cavity of the sealing groove 23. The bottom end of the limit block 4 is connected to the limit post 8. The limit post 8 and the mounting block 22 are slidably connected. The outer end of the limit post 8 is fitted with a spring 9. The two ends of the spring 9 are connected to the limit block 4 and the mounting block 22 respectively. The sealing groove 23 is located directly above the cutting groove 11.

[0019] Aluminum foil packaging boxes are usually cut off by a cutting blade after stamping. The waste generated during the cutting process is mostly treated by an adsorption dust removal mechanism. However, in actual processing, small wastes can easily fall into the inner cavity of the packaging box before it is demolded, either after they are generated or during the adsorption process. These wastes are difficult to detect in time, but they can affect the quality of the product, especially for packaging boxes that need to be sealed later.

[0020] This solution integrates stamping and cutting onto the upper mold assembly 2. When processing aluminum foil packaging boxes, the user lays the aluminum foil on the top of the base 1. Then, the hydraulic cylinder 3 is activated, causing the limiting block 4 to move downwards. The limiting block 4 then moves the upper mold assembly 2 and the tool holder 5 downwards. The first part to contact the aluminum foil is module 21, which presses the aluminum foil into the mold cavity 10 to form a box shape. Once module 21 abuts against the bottom of the inner wall of the mold cavity 10, the hydraulic cylinder 3 continues to move downwards, pushing the limiting post 8 to slide on the mounting block 22 and compressing the spring 9. This forces the tool holder 5 to move downwards within the sealed groove 23, thereby cutting the aluminum foil by embedding the cutting blade 6 into the cutting groove 11, removing excess material outside the edge of the packaging box. After cutting, the user activates the hydraulic cylinder 3 to move upwards a certain distance, allowing... The cutting blade 6 disengages from the cutting groove 11, but the module 21 remains inside the mold cavity 10 without moving, and the bottom end of the mounting block 22 abuts against the surface of the base 1. At this time, the inner cavity of the sealed groove 23 is sealed. The user connects the external waste adsorption mechanism to the connecting pipe 24 through the pipe. The adsorption mechanism can be a common vacuum cleaner or centrifugal pump. Then, the adsorption mechanism is activated to draw air from the inner cavity of the sealed groove 23. Since the sealed groove 23 is sealed at this time, and the aluminum foil cutting position is located inside the sealed groove 23, the waste generated by cutting can be easily sucked away by the connecting pipe 24. At the same time, since the module 21 and the mold cavity 10 enclose the packaging box, the waste cannot enter the inner cavity of the formed packaging box from beginning to end. Also blocked by the mounting block 22, the waste cannot reach the outside, but can only be removed by the adsorption mechanism.

[0021] A rubber pad is connected to the bottom edge of the mounting block 22, and the rubber pad is set around the sealing groove 23.

[0022] The rubber pad in this design can improve the airtightness of the inner cavity of the sealed groove 23, thereby increasing the speed at which waste is absorbed.

[0023] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
