Description

Technical Field

[0001] The utility model relates to the technical field of splitting devices, in particular to a splitting device for high-strength flame-retardant PVC coiled materials. Background Art

[0002] PVC coils are generally produced by calendering. They have less fillers and more plasticizers than PVC floor tiles. Generally, the PVC is plasticized by a four-roll calender. The surface is flat and smooth after calendering. After cooling, the edges are cut and rolled up to become the product. The specifications of the coils vary from country to country. Soft PVC coil floors are softer, have a certain degree of elasticity, and feel comfortable underfoot.

[0003] Authorization publication number "CN216399853U" records "a PVC coil cutting device, comprising a support frame, a rotating shaft is rotatably connected to the top of one side of the support frame, and one end of the rotating shaft is fixedly connected to a placement shaft; a movable groove is opened in the middle of one side of the support frame close to the placement shaft, and the inner wall of the movable groove is movably connected to a connecting rod, one end of the connecting rod is fixedly connected to a fixed frame, and one end of the fixed frame is fixedly connected to a storage groove on the upper surface, and the inner wall of the storage groove is movably connected to a tool holder. This PVC coil cutting device, through the arrangement of the storage groove, the first threaded rod, the tool holder and the handle, the user can hold the handle tightly after completing the cutting work to drive the tool holder to retract toward the storage groove. Under the connection of the first threaded rod, the tool holder as a whole moves with the first threaded rod as the axis, so that the cutting device can reasonably store the tool holder during the idle period, avoid the potential threat of exposed tool holder to the processing personnel, and increase the overall safety of the cutting device."

At the same time, there is no component for leveling the PVC coil. When pulling it out, it is easy to cause overall wrinkles due to its unevenness, affecting the use effect. Utility Model Content
