[0002] Mylar sheet is a widely used insulating material that plays a vital role in electronic devices such as laptops, including circuit board insulation and transformer insulation. In the manufacturing process of laptops, Mylar sheets need to be processed into specific shapes to meet the requirements of different components; therefore, Mylar sheet forming equipment is crucial.

[0003] Early Mylar sheet forming equipment had a relatively simple structure, typically consisting of a basic working platform, simple cutting tools, and a manual or semi-automatic drive mechanism. The working platform only served as a support surface for placing the Mylar sheet raw material, lacking an effective positioning and guiding structure for material transport. Cutting speed and accuracy were difficult to guarantee, making continuous and efficient forming processing impossible.

[0004] Regarding the aforementioned technologies, it has been found that in the existing Mylar sheet forming equipment, the formed Mylar sheets are prone to sticking to the raw material strip during processing, requiring manual separation. This not only increases labor intensity and reduces production efficiency, but may also damage the Mylar sheets during the separation process. Furthermore, the equipment lacks effective collection and diversion devices, making it difficult to quickly collect the formed Mylar sheets, which is detrimental to continuous processing. Utility Model Content

[0021] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:

[0022] Reference Figure 1 , Figure 2 and Figure 3As shown, a Mylar sheet forming device for laptops includes a forming base 1. A positioning hanger 2 is installed on the rear end face of the forming base 1 and is fixedly connected to the forming base 1. A forming cylinder 3 is vertically fixedly installed in the positioning hanger 2, and a forming cutter 4 is fixedly installed at the output end of the forming cylinder 3. Two sets of positioning shells 5 are installed on both sides of the upper end face of the forming base 1, and a guide roller 50 is provided between the two sets of positioning shells 5. A separation component 6 is also provided in the forming base 1, and a flow guide shell 7 is installed on the upper end face of the forming base 1 and is fixedly connected to the forming base 1. The forming base 1 is configured to ensure the stable installation of the positioning hanger 2. At the same time, when forming, the rolled PET strip is passed through both ends of the upper end of the forming base 1. The two sets of positioning shells 5 installed on both sides of the upper end face of the forming base 1 provide positioning for the conveying of the PET strip and prevent the Mylar sheet from shifting during the conveying process. The guide roller 50 is positioned between the two sets of positioning shells 5, which can press and guide the Mylar sheet, keeping it flat during conveying and further improving the forming accuracy. The positioning shell 5 can be made of aluminum alloy, which has the advantages of being lightweight and corrosion resistant. The guide roller 50 can be made of rubber to increase the friction between it and the Mylar sheet, ensuring the stability of the conveying. The forming cylinder 3 serves as the power source, which can precisely control the up and down movement of the forming cutter 4. The forming cylinder 3 can be a common standard cylinder on the market, such as the SC series cylinder, which has the characteristics of large output force and smooth movement. The forming cutter 4 can be made of high-speed steel, which undergoes precision grinding and heat treatment to give it a sharp blade and high wear resistance. It can quickly and accurately cut the Mylar sheet into the required shape, thus enabling continuous cutting and forming processing. The separation component 6 facilitates the quick separation of the formed Mylar sheet from the raw material strip after cutting and forming, and the guide baffle 7 stably discharges the Mylar sheet to the outside. The forming base 1 includes a base box 11 and a work platform 12. The work platform 12 is horizontally positioned on the upper surface of the base box 11 and is fixedly connected to the base box 11. The forming base 1 consists of the base box 11 and the work platform 12. The base box 11 provides stable support for the entire equipment, while the work platform 12 provides a flat working surface for the forming operation of the Mylar sheet. The base box 11 can be welded from high-strength steel to ensure its structural strength and stability. The work platform 12 can be made of smooth stainless steel to reduce the friction between the Mylar sheet and the platform, facilitating the movement of the Mylar sheet and the forming operation.

[0023] Reference Figure 2As shown, the positioning hanger 2 includes a bending seat 21 and a positioning support plate 22 supporting the forming cylinder 3. The positioning support plate 22 is installed on the front end face of the bending seat 21 and is fixedly connected to the bending seat 21. The structure of the bending seat 21 and the positioning support plate 22 of the positioning hanger 2 can stably support the forming cylinder 3. The bending seat 21 can be manufactured using a casting process to ensure the strength and rigidity of its overall structure. The positioning support plate 22 can be fixedly connected to the bending seat 21 by bolts, facilitating the installation and disassembly of the forming cylinder 3. This structural design allows the forming cylinder 3 to remain stable during operation, ensuring the movement accuracy of the forming cutter 4, thereby improving the forming quality of the Mylar sheet.

[0024] Reference Figure 4 and Figure 5 As shown, the separation assembly 6 includes a top plate 61, jet plate groups 62, and an air pump connected to the jet plate groups 62. The top plate 61 is fixedly installed in the worktable 12. The jet plate groups 62 are evenly installed in the top plate 61, and both sides of the jet plate groups 62 are rotatably connected to the top plate 61. The air pump is fixedly installed in the base box 11. A drive cylinder 63 is installed on the top plate 61, and a linkage plate 64 is rotatably connected to the output end of the drive cylinder 63. The linkage plate 64 is rotatably connected to all the jet plate groups 62. The top plate 61 in the separation assembly 6 provides the mounting base for the jet plate groups 62. The jet plate groups 62 are supplied with air by the air pump and can spray gas onto the formed Mylar sheet, so that the Mylar sheet can be quickly separated from the PET belt. A small air compressor, such as a V-0.03 / 8 type air pump, can be used, which has the characteristics of small size and low noise. The cooperation of the drive cylinder 63 and the linkage plate 64 can control the flipping angle of the jet plate groups 62, making the jet direction more flexible and improving the separation effect. The drive cylinder 63 can be a MGPM series thin-type cylinder, which has the advantages of compact structure and sensitive operation. The jet plate assembly 62 includes a tilting plate 621 and an exhaust nozzle 622. The tilting plate 621 is rotatably connected to the top plate 61, and the exhaust nozzle 622 is fixedly installed on the head of the tilting plate 621. The structure of the tilting plate 621 and the exhaust nozzle 622 of the jet plate assembly 62 makes the jetting more concentrated and effective. The tilting plate 621 is rotatably connected to the top plate 61 to ensure its rotational flexibility. The exhaust nozzle 622 can be made of stainless steel and precision machined to give the ejected gas high pressure and flow rate, enabling rapid separation of Mylar flakes.

[0025] Reference Figure 3As shown, the flow guide shell 7 includes a mesh shell 71 and a flow guide ramp 72. The flow guide ramp 72 is installed obliquely within the mesh shell 71 and is fixedly connected to the mesh shell 71. The structure of the mesh shell 71 and the flow guide ramp 72 of the flow guide shell 7 enables the collection and guidance of waste generated during the molding process. The mesh shell 71 prevents Mylar sheet from splashing, while the flow guide ramp 72 guides the Mylar sheet to flow in a designated direction, facilitating its centralized collection. The mesh shell 71 can be made of stainless steel wire mesh, providing good air permeability and protection. The flow guide ramp 72 can be made of plastic sheet with a smooth surface, facilitating the sliding of the Mylar sheet.

[0026] Working Principle: During actual processing, the rolled PET strip passes through the upper end of the forming seat 1, and is positioned by the positioning shells 5 on both sides to prevent displacement. The rubber guide rollers 50 between the two sets of positioning shells 5 press and guide the Mylar sheet, improving forming accuracy. The forming cylinder 3 on the positioning plate 22 drives the high-speed steel forming cutter 4 to move up and down, precisely cutting the Mylar sheet. During processing, air is supplied by an air pump, driving the cylinder 63 and the linkage plate 64 to control the air jet plate group 62 to flip, so that the Mylar sheet is quickly separated from the PET strip. After being formed, the Mylar sheet is blocked and redirected by the mesh shell 71, and the inclined plate guides the Mylar sheet to a designated direction, facilitating rapid collection and continuous processing.
