A coil ironing roller device for a high-speed cold rolling mill, wherein the coil is tightened by an angle roller and then wound on a winding roller, and the ironing roller is installed at one end of a lever; the projection point B of the lever rotation axis, the projection point A of the winding roller axis, and the projection point C of the coil at the departure tangent of the angle roller, are located on the same straight line; the axis projection point of the ironing roller is D; in terms of length, AB=BC, DB=AB+L, wherein 80mm≥L≥35mm. The present invention takes the motion trajectory of the coil cutting point as the research object, so that the ironing roller can be relatively constantly pressed at a position 3-5 cm far from the coil cutting point, so as to achieve the purpose of the best coiling effect. The constant pressure mechanism of the present invention only needs the swing cylinder to output a constant thrust, so that the ironing roller can exert a constant pressure on the coil, thereby simplifying the constant pressure control system of the ironing roller device.

The present invention relates to a strip steel coiling system, a high-strength steel coiling method based on the strip steel coiling system, and a high-strength steel production line using the strip steel coiling system. The coiling system includes a coiler, a steering pinch roller, and a coil unloading car. The steering pinch roller is connected to the coiler through a strip threading guide plate. A bending machine is provided on the material-incoming side of the steering pinch roller. At least one auxiliary pressure roller is arranged around the reel of the coiler. The axial direction of the auxiliary pressure roller is parallel to the axial direction of the reel. The auxiliary pressure roller is provided with an auxiliary pressure roller driving unit so as to have a working position in rolling contact with the steel coil and a standby position away from the steel coil. The bending machine can straighten the strip steel in the early stage of coiling to avoid damaging the strip threading guide plate, and plastically deform the strip steel at the end of coiling, so as to provide back tension for coiling and reduce the rebound force of the outer ring strip steel; the auxiliary pressure roller can make the strip steel adhere to the reel / steel coil during coiling, improve the coiling effect of the strip steel, and avoid problems such as bulging near the jaws when coiling high-strength steel and other steel types.

The utility model discloses a cashmere yarn winding and tensioning device, which relates to the technical field of cashmere yarn production equipment and comprises a worktable, a support is fixedly connected to the front side of the upper end of the worktable, a mounting frame is fixedly connected to the top of the support, two yarn inlet wheels are rotatably mounted in the mounting frame, and an adjusting unit is arranged behind the support. The rear side of the upper end of the workbench is fixedly connected with a pair of mounting plates, the top of the right mounting plate is provided with dismounting parts, a winding roller is arranged between the two dismounting parts, the left side and the right side of the winding roller are sleeved with rotating shafts, the outer side wall of the left mounting plate is fixedly provided with a second driving motor, and the left sides of the mounting plates are provided with stand columns fixedly connected with the workbench. Guiding units are arranged at the front ends of the stand columns. According to the cashmere yarn take-up device, the adjusting unit and the guiding unit are arranged, the tensioning degree of cashmere yarn is adjusted through lifting of the adjusting roller during take-up, the cashmere yarn can be evenly wound on a bobbin through back-and-forth movement of the guiding frame, use is flexible, and the good take-up effect of the cashmere yarn is guaranteed.

The present invention relates to a strip steel coiling device, comprising a frame with a storage groove capable of accommodating a coiling drum, a belt running roller system, a coiling belt wound on the belt running roller system, and an arm mechanism for assisting the coiling of the coiling drum during coiling, and an auxiliary coiling mechanism, the auxiliary coiling mechanism comprising an auxiliary coiling pressure roller and a pressure roller driving unit arranged on the frame, the auxiliary coiling pressure roller is connected to the pressure roller driving unit so as to have a working position and a non-working position, in the working position, the auxiliary coiling pressure roller is close to the strip steel entrance between the auxiliary coiling belt and the coiling drum, and cooperates with the coiling drum to form a strip steel bite pre-bending channel; in the non-working position, the auxiliary coiling pressure roller deviates from the auxiliary coiling belt. The auxiliary coiling pressure roller can apply pressure to the strip steel at the strip steel entrance, so as to achieve the effect of pre-bending the strip steel head, so that the strip steel head is better fitted on the coiling drum and is bitten by the auxiliary coiling belt and the coiling drum, thereby improving the strip steel coiling effect and efficiency, and can better solve the problem that high-strength thick plates are not easy to be coiled in the prior art.

This utility model provides a winding machine for waterproof membrane winding, belonging to the field of waterproof membrane production technology. The winding machine includes a winding machine and a roll support mechanism. A roll is installed on the left side of the inner side of the winding machine, and a feeding frame located outside the roll is installed on the top of the winding machine. A support plate is movably connected to the right side of the top of the winding machine. A support groove is opened on the rear side of the top of the support plate, and an inclined plate is fixedly connected to the left side of the support plate. An adjustment groove is opened at the bottom of the support plate. By setting up the roll support mechanism, a stable medium for supporting the roll can be formed on the top of the winding machine, ensuring that the suspended end of the roll is in a stable state during the winding operation of the waterproof membrane. This avoids the suspended end of the roll shaking during operation, which would interfere with the winding of the waterproof membrane. Therefore, the winding stability and winding effect of the winding machine and the roll are improved.
