The present application relates to the field of vacuum heat sealing, in particular to a vacuum wet extraction heat sealing control method of a textured vacuum bag and a vacuum heat sealer, first, taking the rated speed of the vacuum pump motor as the benchmark N0, setting the starting speed of the vacuum pump motor as N1, the speed of N1 is lower than the speed of N0, driving the vacuum pump to extract vacuum for the textured vacuum bag at the starting speed N1; using a linear pressure sensor to replace a pressure switch to monitor the pressure change of the vacuum cavity in real time, presetting a unit time T and a corresponding preset pressure change value P, when the linear pressure sensor detects that the pressure change value in the vacuum cavity is greater than P within the time range of T, stopping vacuum extraction, and starting the heat sealing bar to heat and seal at the same time; starting vacuum extraction again in the last second of heat sealing, increasing the vacuum degree of the vacuum cavity, forcing the machine to be buckled tighter to enhance the pressure on the bag opening, seal better, and effectively improve the sealing effect of the food containing liquid.

The utility model discloses a three -roller coating device, including frame, install the paint box in the inside of frame, rotate and install the first roller in the inside of paint box, install the second roller in the inside of frame and be in the first roller top, install the third roller in the inside of frame and be in the second roller top, still include setting in the inside of frame and be in the first roller rear scraper mechanism, including transverse fixed in the inside of frame's support beam, the scraper air cylinder of fixed support beam top surface, the utility model puts forward an improved three -roller coating device, and its core innovation lies in on the first roller and added the special scraper mechanism, this design not only solved the problem of paint overflow when high -speed operation, still can through scraper and make the uniform distribution of paint on the roller surface, significantly improved the uniformity of coating after coating, improve the coating quality standard, and this scraper adopts the design convenient to quick assembly and disassembly, simplified maintenance and cleaning process.

This utility model relates to the field of submerged arc furnace technology, specifically a dust collection device for fixed-point casting in front of a metallurgical submerged arc furnace. It includes an enclosed fume hood, a semi-enclosed fume hood connected to one side of the enclosed fume hood, support legs connected to the four lower corners of the semi-enclosed fume hood, and rotating side protection mechanisms symmetrically arranged on both sides of the semi-enclosed fume hood. The rotating side protection mechanism includes two mounting brackets spaced apart on one side of the semi-enclosed fume hood, hydraulic cylinders hinged to the mounting brackets, rotating side protection plates hinged to the piston rods of the two hydraulic cylinders, and a rotating mechanism connected to one end of the rotating side protection plates and between the corresponding two support legs. This device seals the bottom of both sides of the fume hood, reducing flue gas leakage, enhancing dust collection, controlling the concentration of dust during operation, and protecting health and the environment. The symmetrical rotating side protection mechanism prevents molten iron from splashing, preventing burns, eliminating hidden dangers, reducing accidents, ensuring safe production, and solving two major problems of traditional fume hoods.

This utility model provides an adjustable wooden formwork frame structure, belonging to the field of building materials. It includes an aluminum alloy formwork, a wooden formwork, a first connector, and a second connector. The wooden formwork is mounted on the outer wall of the aluminum alloy formwork. The first connector is bolted to the outer wall of the aluminum alloy formwork, and the second connector is bolted to the outer wall of the wooden formwork. A connecting assembly is provided on the outside of the aluminum alloy formwork, and a support assembly is provided on the outer wall of the connecting assembly. In this utility model, a shell is mounted on the surface of the second connector, allowing a wedge block to penetrate the second connector and extend into the interior of the first connector. At this point, the wooden formwork is connected to the aluminum formwork through the shell and the wedge block, forming a unified structure. When concrete impacts the wooden formwork, it remains stable under the counter-support of the shell and the wedge block, preventing gaps between the wooden and aluminum formwork.

This application relates to the field of data backup technology, and discloses a method, apparatus, and storage medium for backing up wireless gun communication data. By employing an adaptive compression algorithm to compress waveform data during TCP disconnection, the problem of memory overflow is solved. Furthermore, by establishing a mapping relationship between workpiece sequence numbers and cache group numbers, access efficiency is improved. After TCP reconnection, the retransmission order is determined based on the mapping relationship, and data is retransmitted in this order, achieving complete data storage during communication interruption and orderly retransmission after reconnection, ensuring data traceability and integrity.
