Therefore, a device is needed to reduce the splashing of plastic during the cutting process. UTILITY MODEL CONTENT

Multiple sets of horizontally distributed limiting rollers 2 are arranged in the middle of the cooling tank 1. Two limiting shafts 3 are arranged parallel to each other at the tail end of the cooling tank 1, below the liquid surface. Equidistant annular grooves 4 are formed on the surface of each limiting shaft 3. A rotating shaft 5 is positioned above the limiting shaft 3 on one side of the head end. An extrusion wheel 6, fitted inside the annular groove 4, is fixedly mounted on the surface of the rotating shaft 5. The extrusion wheel 6 rotates and rubs against the plastic strip, causing it to move. A crossbeam 7 is positioned above the limiting shaft 3 on one side of the tail end. A telescopic sleeve 8 is fixedly mounted at the bottom end of the crossbeam 7. A cutter 9 is fixedly mounted at the free end of the telescopic sleeve 8, fitted inside the annular groove 4.

[0023] There are multiple limit rollers 2 in each group, and the multiple limit rollers 2 are distributed equidistantly in the vertical direction. The number of limit shafts 3 in the vertical direction is the same as the number of limit rollers 2. The upper tangent of the annular groove 4 is located below the lower tangent of the limit roller 2. With this setting, the extruded plastic strips can be arranged in the vertical direction, thereby improving the cutting efficiency.
