3results about How to "Prevent damp caking" patented technology

This invention relates to the field of fish farming technology, specifically to a fish feeding device, comprising a feed storage bin and a mounting bracket installed on the outer wall of the feed storage bin. A discharge pipe is located at the bottom of the feed storage bin, and a first opening / closing assembly, a second opening / closing assembly, and a feed dispensing assembly are sequentially installed inside the discharge pipe from top to bottom. This invention utilizes the linkage design of the first and second opening / closing assemblies. The rotating disc plate rotates, and a rotating long plate is driven to rotate via a first linkage rod. The rotation of the long plate, through a hinged rod, causes the opening / closing plate to slide symmetrically within the discharge pipe, achieving double-layer closure and opening of the discharge pipe. This effectively prevents moisture from contacting the fish feed inside the feed storage bin, preventing the fish feed from becoming damp and clumping.

This utility model discloses a fragment feeding mechanism for powder coating production, including a support frame. A suction component is provided on one outer wall of the top of the support frame, and a material cylinder assembly is provided on the other outer wall of the top of the support frame. The material cylinder assembly includes a material cylinder and two cylinders. A cylinder cover is bolted to the top of the material cylinder, and an installation port is opened on one outer wall of the top of the cylinder cover. A cover plate is installed on one outer wall of the top of the cylinder cover via a movable hinge. The tops of the two cylinders are bolted to the outer walls of the bottom of the support frame. A material holding plate is slidably inserted inside the material cylinder, and a heating element is bolted to the bottom outer wall of the material holding plate. This utility model uses cylinders to drive the material holding plate to rise and fall inside the material cylinder. The material holding plate pushes the fragments upward. At the same time, because the cross-section of the material holding plate is conical, the fragments inside the material holding cylinder move towards the center of the material holding plate, which facilitates the negative pressure adsorption of fragments by the suction pipe. Moreover, during negative pressure suction, residual fragments at the bottom and edges of the material cylinder can be thoroughly removed.
