This utility model discloses a roll forming and coating device for polytetrafluoroethylene (PTFE) glass fiber substrates in the field of substrate coating technology. It includes an operating table, with a first fixed support fixedly connected to the upper center of the operating table. A coating device is disposed at the lower end of the first fixed support. A sliding groove is fixedly formed on the upper end of the operating table, with limiting slide rods fixedly connected to both ends inside the sliding groove. An adsorption and fixing device is slidably connected inside the sliding groove, with the limiting slide rods slidably sleeved on both sides of the adsorption and fixing device. A first threaded rod is rotatably connected to the center of the sliding groove, with one end of the first threaded rod fixedly connected to a first drive motor via a shaft. The first threaded rod is threadedly sleeved on the center of the adsorption and fixing device. This setup uses negative pressure adsorption to fix the substrate, simplifying the fixing and detachment process while avoiding damage to the substrate, providing excellent protection.

This invention relates to the field of advanced manufacturing technology, specifically disclosing an integrated 3D printing and laser processing equipment, including a small integrated device and a large integrated device. The small integrated device includes an integrated housing, a laser cutting area, a mechanical clamping area, a 3D printing area, and control buttons. The laser cutting area is located on one side inside the integrated housing, and the mechanical clamping area is located on the middle side inside the integrated housing. By setting up small and large integrated devices, this invention integrates the two originally independent processes of 3D printing and laser processing into a single device. This significantly shortens the transfer time of parts between different processing stages, effectively avoids the cumulative errors introduced by multiple clamping and positioning, thereby greatly improving overall manufacturing efficiency, while reducing logistics costs and time consumption, bringing a more efficient and precise processing solution to the manufacturing industry.
