This application discloses a foreign fiber removal device for cotton web, relating to the field of textile machinery and equipment. It includes a frame and a feeding conveyor belt, a foreign fiber detection component, and a spray valve assembly mounted on the frame. An impurity collection channel is fixedly provided at the feeding end of the feeding conveyor belt. The impurity collection channel has an upper opening as its inlet and a lower opening as its outlet, with the inlet plane located below the conveying surface of the feeding conveyor belt. The foreign fiber detection component and the spray valve assembly are located above the feeding conveyor belt and the impurity collection channel, with the detection end of the foreign fiber detection component and the ejection end of the spray valve assembly both facing the inlet of the impurity collection channel. This device can perform online foreign fiber detection and positioning on the cotton web output from the carding machine, and spray airflow to accurately eject foreign fibers. Combined with the fan and impurity collection channel, it quickly guides foreign fibers away from the production line, thereby effectively removing foreign fiber impurities from the cotton web and achieving online removal of foreign fibers from the cotton web.

This invention relates to the field of lithium-ion battery manufacturing technology, specifically providing a full-tab battery cell for large cylindrical batteries, its preparation method, and applications. This invention innovatively employs a "winding-fixing-laser axial cutting-graded flattening" process flow, changing the traditional "cut-then-winding" process long used in the industry, achieving a breakthrough in the precision of tab forming. Specifically, after the bare cell is wound, the blank areas of each current collector layer have formed a stable stacked structure, which is precisely fixed using a special fixture and simultaneously cut along the axial direction by laser, completing the high-precision forming of multiple tabs in one step. This method fundamentally eliminates the problem of accumulated deviations caused by step-by-step operations in traditional winding processes, stably controlling the tab alignment accuracy within 0.1mm, effectively solving the long-standing problem of alignment consistency in existing technologies.

The utility model relates to the technical field of battery manufacturing, in particular to a dry-method electrode rolling film-forming production line. The dry electrode rolling film forming production line comprises an extension mechanism, the extension mechanism comprises a driving roller and a plurality of extension rollers matched with the driving roller, the driving roller and the extension rollers are oppositely arranged, the driving roller and the extension rollers are arranged in parallel, and the total length of the extension rollers is smaller than that of the driving roller, the extension rollers and the driving roller which are used for extending a non-coating area of a material belt. Due to the fact that the material belt firstly passes through the extension mechanism to enable the non-coating area to be stretched, and then the coating area is calendered, the non-coating area is calendered and stressed in advance to release stress in advance, when the coating area of the material belt is calendered, the reverse acting force borne by the non-coating area is reduced, and then the flat material belt is obtained. And the non-coating area of the pole piece does not wrinkle after being stretched.

The invention relates to the field of tissue packaging equipment, and discloses a soft tissue packaging machine with a synchronous upward-insertion film package keeping mechanism, which comprises a transfer assembly, a downward-insertion plate sealing assembly, a conveying power source in transmission connection with the transfer assembly, and a material accommodating space between an upper clamping part and a lower clamping part. The lower inserting plate is used for folding the side lower portion of the packaging film at the feeding station, the transferring assembly is provided with at least one end maintaining path between the feeding station and the sealing station, and the attaching plane of the lower inserting plate makes contact with the outer surface of the side lower portion of the packaging film and enables the lower inserting plate to be attached to the side portion of stacked materials all the time on the maintaining path. And the lower inserting plate is withdrawn out of the material accommodating space before reaching the sealing station or when reaching the sealing station. The lower inserting plate and the side lower portion of the packaging film are kept to be attached to the side portion of stacked materials during conveying, the side upper portion of the packaging film can be turned from a drooping state to a natural covering state under the gravity effect in the conveying process, and the problems of loosening and edge warping of the side lower portion of the film material are thoroughly solved.

This utility model relates to a road and bridge crack reinforcement structure, belonging to the technical field of road and bridge crack reinforcement structures. The road and bridge crack reinforcement structure includes: a base, carbon fiber cloth and guide components, a frame, a bidirectional threaded rod, a support frame, guide rollers, and pressure rollers. The guide rollers and pressure rollers rotate on the same horizontal plane. The bidirectional threaded rod can adjust the distance between the two support frames to accommodate reinforcement requirements of carbon fiber cloth of different widths. Guide rollers and pressure rollers are movably inserted into the two support frames to ensure the carbon fiber cloth remains flat during laying. The guide components are located on both sides of the support frames and are movable at both ends of the guide rollers to prevent the carbon fiber cloth from shifting during laying. The carbon fiber cloth is movably sleeved on the surface of the bidirectional threaded rod, with one side sliding along the surface of the guide rollers and pressure rollers. Through the compaction action of the pressure rollers, the carbon fiber cloth is tightly adhered to the crack surface, thereby effectively improving the load-bearing capacity and durability of the bridge structure.

The utility model relates to the technical field of textile fabric printing and dyeing, in particular to an efficient short-process textile fabric printing and dyeing device which comprises a printing and dyeing box, the inner side of the printing and dyeing box is rotationally connected with multiple sets of guide rollers, the position, close to the bottom end, of the inner wall of the printing and dyeing box is rotationally connected with a dip dyeing roller, and the dye liquor amount of the inner side of the printing and dyeing box is higher than the top face of the dip dyeing roller. A drying box is installed on one side of the printing and dyeing box, a water squeezing assembly is installed on the side, close to the drying box, of the printing and dyeing box, a discharging port is formed in one side of the drying box, a feeding port is formed in one side of the printing and dyeing box, and a double-face drying mechanism is installed on the drying box. The double-face drying mechanism comprises a flow dividing assembly, a rolling and pushing assembly and a movable assembly. The fabric drying device is simple in structure, convenient to operate and capable of drying the two faces of a fabric, the fabric can be flattened during drying, the surface of the fabric is free of wrinkles, practicability is further improved, and the subsequent printing and dyeing effect is guaranteed.
