5results about How to "Increase unit capacity" patented technology

The application provides a pickling unit automatic speed control method and system based on multi-factor constraints, and relates to the technical field of cold-rolled strip steel production. In view of the defects that the existing control relies on manual operation or primary automation and is difficult to cope with multiple constraints and instantaneous working conditions, the method comprises the following steps: constructing a multi-factor constraint model covering process, equipment, logistics, acid liquid and instantaneous working conditions; collecting corresponding data in real time; dynamically calculating a global optimal speed setting value through multi-layer decision logic, calculating a basic speed first and then superimposing an instantaneous working condition constraint, and directly triggering emergency disposal through high-priority alarm; issuing an instruction for execution and closed-loop feedback, and combining machine learning for self-learning optimization. The application realizes automatic intelligent control of the unit speed, guarantees quality and equipment safety, improves production efficiency and continuity, and reduces energy consumption cost.

This invention discloses a hot melt adhesive for high-temperature protective clothing and its preparation method, comprising the following raw materials: Fischer-Tropsch wax, styrene-isoprene-styrene block copolymer with 0% diblock content, styrene-isoprene-styrene block copolymer with 20-30% diblock content, styrene-isoprene-styrene block copolymer with 40-50% diblock content, rosin resin, petroleum resin, ethylene-vinyl acetate copolymer, and antioxidant. This hot melt adhesive requires no toxic solvents, possesses both heat resistance and water resistance, and is suitable for high-temperature protective clothing. The preparation method of this hot melt adhesive involves heating and mixing polymer materials without adding any solvents or toxic substances during the preparation process, reducing the risk of toluene poisoning, completely solving the problems of solvent evaporation and recovery, and, more importantly, eliminating safety hazards in the storage and use of organic chemicals, achieving environmentally friendly, safe, and efficient production.

The invention relates to the technical field of electric digital data processing, in particular to a dynamic scheduling method and system for a garment production line based on digital twinning, and the method comprises the steps: receiving a plurality of garment orders sent by a customer, and according to the first description information of a garment process in the garment orders, generating a plurality of garment production lines; grouping the clothing orders in each preset time period to obtain a plurality of order groups; according to the first description information, generating production processes corresponding to the clothing process, and based on second description information for clothing materials in the clothing order, grouping the production processes to obtain a plurality of process groups; based on the parameters of the digital twin model corresponding to the production equipment, clustering operation is carried out on the process groups in the same order group to obtain a plurality of clusters, and the execution sequence of the process groups in the order group is determined according to the clustering distance between the process groups in the clusters and the production equipment; and sending the execution sequence to an edge end corresponding to the clustering cluster.

This utility model relates to a novel grinding disc-assisted grinding device for a sand mill, comprising a frame, a variable frequency motor fixedly installed inside the frame, a bearing seat fixedly installed above the frame, a drive shaft mounted on the bearing seat, the variable frequency motor and the drive shaft connected by a drive belt device, a grinding cylinder fixedly mounted on the bearing seat by grinding cylinder fixing bolts, and an end cap fixedly mounted on the other end of the grinding cylinder by end cap fixing bolts. The bearing seat, grinding cylinder and end cap form a sealed grinding chamber, in which a grinding disc, a conical spacer and a rotor are arranged. The conical spacer is a spacer with a tapered structure. The grinding disc and the conical spacer are mounted on the drive shaft, and the rotor is mounted at the farthest end of the drive shaft. The stirring device composed of the grinding disc, the conical spacer and the rotor rotates with the drive shaft. This utility model solves the problems of traditional cylindrical spacers not being able to fully utilize the grinding chamber space and having low grinding efficiency, and square spacers having high energy consumption and relatively insufficient uniform mixing ability.

The utility model relates to the technical field of fermented bean curd, specifically relates to a multilayer fermented bean curd fermentation frame, including multigroup vertical interval arrangement's through -and -through tray, the inside lower side wall fixed limit strip for supporting embedded hole -like board of tray, the both sides of hole -like board are equipped with pull rope and is convenient for to extract, the rotating plate of rotating groove is fixed in the middle of tray one end, the rotating bearing installed in the groove is arranged on the outside of support column and forms the rotating pivot, need to operate when horizontally pulling tray, rotating bearing rotates along the support column and makes the layer to slide outward, through pull rope to take out hole -like board and its carried bean curd blank, complete detection or replacement operation in open space, after reset, hole -like board returns to limit strip fixed, multilayer tray keeps vertical ventilation state, the structure will traditional longitudinal operation change into horizontal operation, eliminate the need of interlayer reserved arm operating space, make interlayer distance need only satisfy the thickness of bean curd blank and bearing structure, significantly improve the stacking density and capacity in the same space.
