7results about How to "Improve folding efficiency" patented technology

This utility model relates to a folding mechanism for producing double-sided QR code labels, belonging to the field of label folding technology. It includes a base, a pre-lifting block, and a flattening block, both mounted on the base. The base is equipped with a driving component for moving the label. The pre-lifting block has a pre-lifting groove for the label to pass through, and the flattening block has a flattening groove for the label to pass through. A pre-lifting auxiliary block with a pre-lifting inclined surface is disposed within the pre-lifting groove, and a flattening auxiliary block with a flattening inclined surface is disposed within the flattening groove. The driving component includes a driving roller rotatably mounted on the base, which flattens the folded label. This application improves label folding efficiency.

This invention belongs to the field of bioengineering and enzyme engineering technology, specifically relating to a method for improving the soluble expression and catalytic activity of chondroitin 4-O-sulfotransferase. Using chondroitin 4-O-sulfotransferase MamC4ST as the research object, this invention constructs various fusion expression systems of soluble tags in prokaryotic hosts, and systematically evaluates its soluble expression behavior and catalytic performance under different host strains and molecular chaperone co-expression conditions. The MBP tag has significant advantages in improving the soluble expression of MamC4ST; under the synergistic effect of the GroEL / GroES molecular chaperone, the recombinant engineered strain MBP-Δ60MamC4ST-Shuttle7-pGro7 exhibits excellent catalytic performance on chondroitin substrates, with conversion and sulfation rates reaching 98.41% and 95.03%, respectively, at a substrate concentration of 2 g / L.

The application discloses a wind guide component for adjusting indoor air quality of high-rise buildings and an adjusting system, and belongs to the field of ventilation of high-rise buildings. The application is used for solving the problems existing in the natural ventilation of the high-rise buildings. The application comprises a top plate, a bottom plate and a wind baffle. The top plate and the bottom plate are arranged in parallel on the wall above and below the outer window. The top plate and the bottom plate are both triangular plate structures. The long straight edge of the triangular plate is fixed to the wall where the outer window is located, the short straight edge of the triangular plate is perpendicular to the wall where the outer window is located, and an arc-shaped track is arranged on the inclined edge of the triangular plate. The arc-shaped track is close to the short straight edge of the triangular plate. The wind baffle comprises a square frame and a louver fan. A plurality of louver fans are arranged in parallel in the square frame. One vertical edge of the square frame is hinged to the right-angle vertex of the top plate and the bottom plate. The other vertical edge of the square frame slides along the two arc-shaped tracks to adjust the included angle between the windward surface of the wind guide component and the wind direction.

The utility model provides a gift box automatic folding device convenient to adjust, include: workstation, mounting bracket, placing mechanism, first drive mechanism, second drive mechanism and bending mechanism, the workstation has set up the placing groove on one side, placing mechanism sets up in the placing groove, mounting bracket sets up on one side of the workstation, just the mounting bracket part is located above placing mechanism, first drive mechanism with second drive mechanism all set up on the mounting bracket, first drive mechanism is used for driving bending mechanism. Use this convenient to adjust's force to split and automatic folding device to carry out processing, through the cooperation and installation of workstation, mounting bracket, placing mechanism, first drive mechanism, second drive mechanism and bending mechanism, can fold the carton of different size, the overall folding efficiency is high, and need not to carry out replacement in the middle, simple and convenient, can satisfy use demand very well.

This utility model discloses a device for assembling ship sections, specifically relating to the field of assembly technology. It includes a support base, with support frames fixedly connected to both the left and right ends. Four slide rails are fixedly connected to the top of the support base, with the bottom left and right sides of each slide rail contacting the top of the support frame on the same side. An assembly assembly is installed inside the support base, and two adjustment components are located above the support base. This device for assembling ship sections, by setting up the assembly assembly, specifically involves activating a motor to move two moving blocks closer together. As the two moving blocks move closer, the ship sections placed on top of them can be precisely assembled. This eliminates the need for repeated manual adjustments, reducing the difficulty of subsequent welding and assembly. Furthermore, the entire assembly process can be completed automatically, enabling rapid ship section assembly operations and improving the efficiency of ship assembly.

This utility model discloses a folding cap structure for a carton sealing machine, including a conveyor housing. A height frame is fixedly installed in the middle of the conveyor housing. Lifting grooves are provided on both sides of the inner wall of the height frame. Lifting blocks are slidably connected inside the two lifting grooves. A movable shell is fixedly installed between the two lifting blocks. Two movable blocks are provided at the bottom of the movable shell. Folding cap components are fixedly installed on one side of each of the two movable blocks. This folding cap structure for a carton sealing machine, by setting up folding cap components, a lead screw, and two movable blocks, allows the two movable blocks to slide relative to each other along the rotating lead screw, adjusting the distance between the two folding cap components. The first sliding block slides along the first sliding groove, adjusting the angle between the connecting table and the length plate, indirectly adjusting the folding angle of the folding cap components. This facilitates the carton sealing machine to flexibly fold cartons of different specifications. The overall operation is simple and convenient, improving the folding efficiency of the carton sealing machine.

This application discloses a folding clothes hanger, including a hook and hanger arms. The hook is rotatably connected to at least two hanger arms. The hanger arms can be unfolded or folded by rotation. Each hanger arm has a first receiving cavity. A linkage is rotatably installed in the first receiving cavity. The linkage is connected to a clip. The linkage rotates inward to drive the clip into the first receiving cavity. The linkage rotates outward to drive the clip out of the first receiving cavity. By adding a first receiving cavity to completely store the clip, and by adding a linkage to allow the clip to be completely detached from the first receiving cavity during use, the use of the clip is not interfered with. This not only meets the needs of space utilization and portability, but also improves the practicality of the clothes hanger.
