This utility model relates to the field of film winding machine technology, specifically a film winding machine for reverse osmosis membrane processing: it includes a support frame, a first motor fixedly connected to the surface of the support frame, a take-up roller mounted on the output shaft of the first motor, and a constant pressure mechanism provided on the surface of the support frame, the constant pressure mechanism including a guide rail fixedly connected to the surface of the support frame. This utility model uses the output shaft of a second motor to drive a bidirectional lead screw to rotate. The bidirectional lead screw, through rotation, drives two sets of square nuts to slide on the surface of the support frame. During the sliding process, the square nuts drive a lifting plate to rise and fall via an adjusting rod. The lifting plate, during its sliding process, drives a lifting bracket and a pressure roller to rise and fall, thereby changing the pressure value of the pressure roller on the membrane material on the take-up roller. This ensures that the pressure roller always applies constant pressure to the membrane material on the take-up roller, ensuring that the membrane material is tightly wound on the take-up roller, reducing membrane roll slack and deformation, and improving the quality of winding.

This utility model relates to the field of fire-fighting equipment technology, specifically a vehicle-mounted integrated hose reeling and cleaning machine. It includes a vehicle body, a fixed bracket, a hose reeling / unwinding device, and a guiding and cleaning device. The fixed bracket is mounted on the vehicle body, and the hose reeling / unwinding device and the guiding and cleaning device are respectively located on both sides of the fixed bracket. The hose reeling / unwinding device is used to reel in and unwind empty hoses. During reeling, the guiding and cleaning device guides the empty hoses towards the hose reeling / unwinding device. The guiding and cleaning device includes an adjustment component, a guiding component, and a cleaning component. The adjustment component is mounted on the fixed bracket. This utility model achieves integrated hose reeling / unwinding and cleaning operations, significantly improving work efficiency, reducing labor costs, and providing strong technical support for fire-fighting operations.

This utility model belongs to the field of cable processing technology and discloses a winding machine for cable processing, including a base plate, a support plate fixedly connected to the upper surface of the base plate, a winding cylinder fixedly connected to the outer surface of the support plate, a mounting base fixedly connected to the outer surface of the support plate, a first motor fixedly connected to the lower surface of the mounting base, a lead screw fixedly connected to the output end of the first motor, a threaded block threadedly connected to the lead screw, a rotating rod rotatably connected to the threaded block, and a tensioning wheel fixedly connected to the other end of the rotating rod. A sliding groove is provided on the base plate, and a slider is slidably connected in the sliding groove. Through the cooperation of the first motor, lead screw, threaded block, rotating rod and tensioning wheel, the cable can be tightened. The height position of the tensioning wheel can be adjusted according to the material or tightness of the cable, so as to obtain the optimal tension suitable for different types of cables. Reasonable tension force and tension uniformity help the cable to be wound flat and compactly.

This invention discloses a multi-roller winding device for high-voltage bushing capacitor cores, including a winding roller, a winding heating roller mechanism disposed on both sides of the winding roller, and a winding lifting mechanism that drives the winding roller to lift. The winding heating roller mechanism includes two heating rollers symmetrically disposed on both sides of the winding roller and multiple sets of clutch adjustment mechanisms arranged along the length of the heating roller and adjusting the distance between the two heating rollers. Oil circulation temperature control devices are respectively installed at both ends of the winding roller. This invention is rationally designed, connecting two oil circulation temperature control devices to two heating rollers to form a circulating heating circuit, ensuring the temperature of the heating rollers and further ensuring the dryness of the capacitor core during winding. Simultaneously, multi-roller collaboration is employed during winding, with both the winding roller and the heating roller having winding power, collaboratively completing the winding of the insulating paper in the capacitor core, ensuring stable and tight winding of the insulating paper, and improving the performance of the capacitor core.

This utility model relates to the field of high-speed printing thermal materials technology, and in particular to a winding tension adjustment mechanism for high-speed printing thermal materials. It includes an unwinding roller and a tension adjustment component. An antistatic component is located on the side of the tension adjustment component away from the unwinding roller, and a dust removal component is located on the side of the antistatic component close to the tension adjustment component. A pressing component is located on the antistatic component, and a winding roller is located on the side of the antistatic component away from the tension adjustment component. The antistatic component includes a lower housing and an upper housing. A feed inlet is opened on the side of the lower housing and the upper housing close to the tension adjustment component. An ionizer is installed inside both the lower housing and the upper housing. In this utility model, static electricity can be eliminated before the thermal material contacts the winding roller, preventing the thermal material from developing micro-wrinkles or unevenness due to static electricity, which could cause gaps and allow air to enter. This avoids the phenomenon of the outer layer material wrinkling the inner layer material after winding.
