Tea bag packer

The invention discloses a tea bag packer. A hanging wire coil component thereof comprises a central shaft, wherein one end of the central shaft is fixedly connected to a frame; a shaft sleeve is assembled on the periphery of the central shaft by rotating the shaft; a hanging wire coil is coaxially fixed with an external end face of the shaft sleeve away from the frame along the radial direction; hanging wire claws extending along radial direction are uniformly distributed on the periphery of the hanging wire coil; a support rod for supporting cotton wires is slidingly penetrated through each hanging wire claw along the radial direction of the hanging wire coil; a cam connecting rod transmission mechanism which is in transmission connection with each support rod and drives the support rod to have linear reciprocating motion along the axis thereof is sleeved on the periphery of the shaft sleeve close to the hanging wire coil; and the cam is fixedly connected to the frame. Through the structure of the invention, the cotton wire can avoid the non-heat-seal area on the tea bag when the cotton wire is heat-sealed with the tea bag, so as to prolong the sealing length between the cotton wire and the tea bag, enhance the connecting strength between the cotton wire and the tea bag and avoid the phenomenon in the prior art that the cotton wire drops off.

Bionic concrete artificial fish reef and preparation method thereof

The invention discloses a bionic concrete artificial fish reef arranged on the seafloor. According to the fish reef, C40 concrete is used for pouring to form an artificial fish reef base body, the surface of the base body is covered with a protective layer which is composed of cement mortar, biological calcium carbonate and oyster shells, the biological calcium carbonate is made of eggshells, corals, seashells and fishbone and is used as an additive to be added into the cement mortar, the cement mortar mixture is smeared on the surface of the fish reef base body to form cement paste after the biological calcium carbonate and the cement mortar are evenly stirred together, and the oyster shells are inlaid in the cement paste in a convex face outward mode. According to the artificial fish reef, the environment-friendly function, the durable function and the trapping function are integrated, the cement mortar covering layer doped with the biological calcium carbonate and the coating of the oyster shells can attract marine organisms to inhabit, and thus the trapping effect of the artificial fish reef can be better achieved; compared with a traditional concrete fish reef, the artificial fish reef has good waterproof property and chloride ion resistance, surface roughness and alkalinity of the surface of the fish reef are appropriate, bionic performance is achieved, and the fish collecting effect is excellent.
