The invention discloses an etching machine for a display screen PCB, and relates to the technical field of wet etching, the etching machine comprises a workbench, a rotating roller device, a first hydraulic cylinder, a second hydraulic cylinder, a motor, an air blowing fan and a rotating sprayer, the bottom of the inner wall of the workbench is provided with a water storage tank, the bottom of the water storage tank is provided with a water outlet, the rotating roller device is arranged on the inner wall of the workbench, and the rotating roller device is arranged on the inner wall of the workbench. The first hydraulic cylinder is fixedly installed on the outer wall of the workbench, the second hydraulic cylinder is fixedly installed on the outer wall of the workbench, and the control device is used for controlling whether the rotating spray head is communicated with the first hydraulic cylinder or not and arranged on the inner wall of the workbench and controls fluid to be connected or disconnected through mechanical coincidence and dislocation of through holes of the second water conveying opening and the first water conveying opening. Rapid and accurate response without an intermediate link is realized, and uneven etching caused by spraying angle deviation or valve delay is effectively eliminated.

This utility model discloses a hammering mechanism for processing bait cakes, belonging to the field of bait cake processing technology. The hammering mechanism includes a base and a bracket mounted on the base, and further includes a disc rotatably connected to the base. Multiple sets of springs are arranged equidistantly in a ring on the disc. A mounting plate is fixedly connected to the disc, and the ends of the springs are respectively connected to the disc and the mounting plate. A feeding bowl for dispensing material is fixedly mounted on the mounting plate. When the bait cake material moves to the detour section, it flips downwards, creating a flipped edge effect. This achieves the effect of flipping the edges of the bait cake material during hammering, preventing it from sticking to the inner wall of the feeding bowl, while ensuring that every side and part of the bait cake receives uniform hammering force. This avoids areas with uneven hardness and residual granular texture, reduces the need for manual flipping, and increases the safety of bait cake production.
