Abstract

The invention belongs to the technical field of perimeter guard plate production, and proposes a steel coil perimeter guard plate production line, which includes an extrusion device, a three-roller calendering device, a tensioning device, a cooling device and a cutting device arranged in sequence. The extrusion device includes two A horizontally arranged barrel, one end of the barrel is a closed end, and the other end is an output end. The two output ends are close to each other and are connected to the distributor. The distributor includes a main material inlet and an auxiliary material inlet near the output end. The main material inlet is connected to the distributor. The auxiliary material inlets are all connected to the split flow pump, and the split flow pump is connected to the main flow channel and the auxiliary flow channel. The main flow channel is close to the converging flow channel. There are pressure rollers, and the pressure rollers are arranged at both ends along the thickness direction. The direction is vertical, which solves the technical problems of excessive equipment, high cost, and low quality of the perimeter guards in the existing production of steel coil perimeter guards.

Description

technical field [0001] The invention belongs to the technical field of steel coil protection, and relates to a steel coil peripheral guard plate production line. Background technique [0002] Steel coils are difficult to transport due to their heavy weight during transportation, and the transportation environment is difficult to guarantee. Since steel coils are steel, they are prone to corrosion when exposed to acid and water, and collisions are likely to occur when transporting and rolling, resulting in deformation or damage to the steel coils. The value of the steel coils If the protection of the steel coil is not paid attention to, it will cause great economic losses. Therefore, the steel coil produced by the general manufacturer will be wrapped with a circumferential guard plate when it leaves the factory. Chemical extrusion, cooling, cutting and segmentation, etc. The material of the peripheral guard plate is generally polyethylene on the upper and lower surfaces and po...
