The utility model discloses a box folding machine for a special-shaped airplane box. The box folding machine comprises a paper box conveying mechanism, a buckling assembly, a forming mechanism, a sliding frame and a page turning metal plate. The paper box conveying mechanism conveys a box paper plate to the forming mechanism, and the buckling assembly drives a buckling plate through a lifting plate and a buckling air cylinder to complete folding and buckling of buckling pages. The forming mechanism comprises an upper folding device and a lower discharging device, the upper folding device folds a paper box through a main plate folding metal plate, a bottom insert jacking plate, a side plate inclined pushing metal plate and a front insert, and the lower discharging device completes front plate buckling and discharging through a push plate and a suction cup; the sliding frame and the page turning metal plate cooperatively control the buckling page to be turned towards the middle part; full-automatic forming operation of the special-shaped aircraft box can be achieved, and the production efficiency, adaptability and forming precision are remarkably improved.

This utility model discloses a reflective folding raincoat, which includes a main body, a folding assembly disposed on the rear side of the main body, and a pull-out assembly disposed inside the folding assembly. The main body includes a garment section and sleeves disposed on both sides of the garment section. Passive blocks and male fasteners are sewn onto the side walls of the garment section, and active blocks are sewn onto the side walls of the sleeves. This reflective folding raincoat, by setting passive blocks in the garment section and active blocks in the sleeves, allows for quick and accurate folding of the garment, reducing space occupation. Simultaneously, after rolling up from the bottom, pulling the pull-out assembly in the folding assembly causes the elastic band to wrap around the rolled-up raincoat, and then using the female and male fasteners to complete the roll-up, facilitating storage. Furthermore, during normal use, the pull-out assembly springs back into the folding assembly without affecting use, and the flashing strip on the folding assembly increases safety.

The utility model discloses rapid folding and flattening equipment for carton production, and belongs to the technical field of carton processing devices. The device comprises a rack, a frame body and a spring, a flattening part is arranged on the rack, U-shaped plates are installed on the two sides of the rack, first electric push rods are installed in the middles of the U-shaped plates, push plates are installed at the output ends of the first electric push rods, T-shaped blocks are arranged in the push plates, and abutting blocks are installed at the bottoms of the T-shaped blocks. According to the carton folding device, the carton is folded through the push plate and the abutting block, the two sides of the unfolded carton are rapidly and accurately folded, the step of manual folding is avoided, the production cycle of the carton from raw materials to finished products is shortened, the overall production efficiency is remarkably improved, it is guaranteed that the carton is evenly stressed in the folding process, and the production efficiency is improved. The problems of irregular shapes, corner upwarping and the like possibly caused by manual folding are avoided, so that finished cartons are regular in shape and uniform in size, the overall attractiveness and practicability of the cartons are improved, and follow-up flattening of the cartons is facilitated.

This invention discloses a self-cleaning conveyor device for peanut processing, relating to the field of peanut production. It includes a support frame with a control panel mounted on one side. Drive rollers are rotatably mounted on the inner sides of both ends of the support frame. A vibrating contact rod contacts the inner side of the conveyor belt at multiple positions, creating a squeezing vibration. The squeezing mechanism drives the auxiliary roller frame, rotatably connected to both sides of the contact roller frame, to adjust its angle. During adjustment, the auxiliary roller frame folds the belt's bending area, achieving anti-splashing and conveyor belt tension adjustment. This self-cleaning conveyor device for peanut processing, in conjunction with an upper vacuum cleaner body, continuously absorbs dust, forming a dual dust removal closed loop of vibration shaking and negative pressure adsorption, completely solving the dust residue problem. Simultaneously, the vibration mechanism triggers the squeezing and driving mechanisms, forming a closed protective frame to prevent peanuts from splashing and scattering, while also ensuring continuous conveyor belt tension through folding tension.

The application discloses a mobile labor-saving folding welding workbench and belongs to the technical field of welding tool equipment. In view of the problems that the existing welding workbench needs side turning operation, is labor-consuming and has safety hidden dangers when being folded, the application provides a workbench which can be automatically and slowly folded in a standing state. The workbench comprises a table panel, two groups of supporting foot supports hinged to the lower end of the table panel, a synchronous rotating structure, a locking and energy releasing delay device and a fixable roller. The synchronous rotating structure is connected with the two groups of supporting foot supports through a gear driving assembly, a connecting shaft and a driving handle, and can drive the two groups of supporting foot supports to be synchronously folded or unfolded. The locking and energy releasing delay device comprises a preliminary braking structure and an energy storage locking structure. The preliminary braking structure is preliminarily locked through the friction force between a braking block and the connecting shaft, and the energy storage locking structure accumulates energy through an energy storage spring and drives the supporting foot supports to be automatically folded after being unlocked. The operator only needs to assist in supporting and does not need to bear the weight of the workbench.

The invention discloses a cutinase mutant gene, a protein expressed by the cutinase mutant gene and application of the cutinase mutant gene. The protein expressed by the cutinase mutant gene can be correctly folded and can be massively purified in an escherichia coli system. Meanwhile, the mutant protein disclosed by the invention has the function of degrading PET (Polyethylene Terephthalate) by wild cutinase, and the catalytic efficiency of the protein expressed by the cutinase mutant gene is improved compared with that of a control group. The protein expressed by the keratin mutant gene has activity and stability at 40-80 DEG C. Specifically, when the pH value is 8.0 and the temperature is 72 DEG C, the PET degradation capacity is improved by 20% compared with that of a control group, and when the pH value is 8.0 and the temperature is 60 DEG C, the PET degradation capacity is improved by 70% compared with that of the control group.
