Description
Technical Field
[0001] This utility model relates to the field of plastic steel strip roller cutting technology, and in particular to a roller cutting device for plastic steel strip production. Background Technology
[0002] Plastic steel strapping is a high-strength packaging strap made primarily of PET. It features high tensile strength and is not easily broken, making it a substitute for traditional steel strapping for cargo bundling. It also offers advantages such as lightweight, corrosion resistance, and recyclability, and is widely used in heavy-duty packaging in industries such as logistics, building materials, and metallurgy.
[0003] The production process of PET steel strip is as follows: after drying, PET raw materials are melted and plasticized by an extruder and extruded into thick sheets. After longitudinal stretching and transverse shaping, the sheets are cooled and solidified by cooling rollers, and then cut into strips of a set width by a slitting machine. Finally, they are wound into rolls by a winding machine. Some of them need to be further embossed or dyed. The strength and flatness of the strip are ensured throughout the process by a temperature control and tension control system.
[0004] Existing plastic steel strips produce debris when cut with roller cutters. The debris accumulates between the roller cutters, which reduces the cutting accuracy and causes roughness in the cut. Utility Model Content

[0033] Working principle: The cooled plastic steel strip is pulled from the middle of a pair of roller cutters 13 to the middle of the take-up shaft 11. The roller cutters 13 are activated, cutting the plastic steel strip. The take-up shaft 11 then rewinds the plastic steel strip. As the roller cutters 13 continue to cut the plastic steel strip, debris is generated. At this time, the motor 15 can be activated to drive the slider 14 to slide back and forth on the top of the first support frame 12. During the sliding process, the support rod 16 drives a pair of cleaning brushes 17 to slide together. The cleaning brushes 17 can interact with the roller cutters 13... 3. Contact friction removes debris from the plastic strip cut by the roller cutter 13. The plastic strip can be first pulled from the top of the support shaft 23, and then pulled to the middle of the roller cutter 13. When the plastic strip shifts to one side, the first electric push rod 22 can be activated to push the first support seat 2 to slide on the top of the worktable 1. Then, the plastic strip on the top of the first support seat 2 can be pushed to the middle of the worktable 1 by the pushing force of the first electric push rod 22 and continue to be conveyed. After the roller cutter 13 cuts the plastic strip, multiple sets of heating plates 31 can be activated to heat the plastic strip after cutting. The edge will contact the heating plate 31, which will heat and eliminate the burrs produced during cutting. When the heating plate 31 heats and trims the burrs on the plastic strip, polluting gases will be generated. At this time, the air pipe 42 can be connected to a vacuum cleaner, and the vacuum head 41 can then absorb the gases generated by the heating plate 31 during burr removal. When the take-up shaft 11 winds up the cut plastic strip, the second electric push rod 51 can be activated, driving the rotating shaft 52 to approach the plastic strip being wound by the take-up shaft 11. During the winding process, the take-up shaft 11 applies pressure to the plastic strip, causing... The plastic steel belt is tightly wound by the reel 11. The cut plastic steel belt can pass through the middle of a pair of cleaning blocks 61. Then the cleaning blocks 61 can clean both sides of the plastic steel belt. When the cleaning brush 17 sweeps away the debris on the surface of the roller cutter 13, the debris can fall into the collection box 7. The collection box 7 collects the debris. When the first electric push rod 22 pushes the support shaft 23 to move, the friction pad 8 can increase the friction between the plastic steel belt and the first support seat 2, so that the plastic steel belt moves along with the friction of the friction pad 8 when the first support seat 2 moves.
[0034] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
