Description

Technical Field

[0001] The utility model relates to the technical field of tube forming, and specifically relates to a heat shrink tube cutting machine. Background Art

[0002] Heat shrinkable tubes include PVC heat shrinkable tubes and PET heat shrinkable tubes. PVC heat shrinkable tubes are widely used for the outer covering of various tubular items such as curtain rods, shower curtain rods, hanging rods, mop rods, broom handles, tool rods, etc., and can be used for the identification and insulation outer covering of low-voltage indoor busbars, joints, and wiring harnesses. PET heat shrinkable tubes are superior to PVC heat shrinkable tubes in terms of heat resistance, electrical insulation performance, and mechanical properties, and are more in line with environmental protection requirements, but the cost is also relatively high. Heat shrinkable tubes need to be cut to a fixed length during the molding process. Existing tube cutting machines, such as the Chinese patent authorization announcement number CN215093812U, disclose a heat shrinkable tube cutting machine. Through the setting of the propulsion wheel, the heat shrinkable tube can be driven by friction to pass through the propulsion wheel to reach the bottom of the cutter for cutting. However, the distance between the two propulsion wheels is inconvenient to adjust, and it is difficult to apply to heat shrinkable tubes of different diameters. For this reason, a heat shrinkable tube cutting machine is proposed. Utility Model Content
