Description

Technical Field

[0001] This utility model relates to the field of packaging paper production technology, specifically to a cigarette packaging paper rolling and cutting device. Background Technology

[0002] Currently, when using a roll-cutting device to roll-cut cigarette packaging paper, the rolling cutter on the lower cutter roller rolls the cigarette packaging paper to form shaped paper and waste material on the upper cutter roller. A waste removal needle on the lower cutter roller traps the waste material on the upper cutter roller and pulls it off. A scraper then removes the waste material from the waste removal needle and the lower cutter roller. However, in existing roll-cutting devices, the diameter of the waste removal needle gradually increases from the needle tip to the point of connection with the lower cutter roller. The paper becomes increasingly tightly trapped on the waste removal needle, and if the paper is not removed in time, it accumulates to a certain extent. Because the waste cannot be expelled promptly, the waste removal needle collides with the scraper, making it prone to breakage. Utility Model Content

The upper cutting roller 2 and the lower cutting roller 3 are rotatably connected to the support member 1. The upper cutting roller 2 includes a forming area disposed on the side, a waste area disposed on the side, and an insertion hole disposed on the waste area and matching the waste removal needle 4. The waste removal needle 4 includes a needle tip 41 and a connection point to the lower cutting roller 3. The mounting part 43 is connected to the side, and the recessed part 42 is recessed between the needle tip part 41 and the mounting part 43; when the upper cutter roller 2 and the lower cutter roller 3 rotate, the rolling cutter is used to roll and cut the packaging paper to form the shaped paper and the waste material located on the upper cutter roller 2. The needle tip part 41 is used to insert into the insertion hole and hold the waste material. The needle tip part 41 is used to drive the waste material to detach from the upper cutter roller 2, so that part of the waste material is connected to the needle tip part 41 and the other part is connected to the lower cutter roller 3. The recessed part 42 is used to receive the waste material that slides down from the needle tip part 41. The scraper 5 is used to scrape the waste material off the waste removal needle 4 and the lower cutter roller 3.

[0020] Here, the upper cutter roller 2 and the lower cutter roller 3 rotate in corresponding directions. When the upper cutter roller 2 rotates at a first preset angle and the lower cutter roller 3 rotates at a second preset angle, the rolling cutter rolls the packaging paper to form shaped paper and waste material, which adheres to the surface of the upper cutter roller 2. When the upper cutter roller 2 rotates at a third preset angle and the lower cutter roller 3 rotates at a fourth preset angle, the needle tip 41 rotates to insert into the insertion hole and secures the waste material. When the upper cutter roller 2 rotates at a fifth preset angle and the lower cutter roller 3 rotates at a sixth preset angle, the needle tip 41 drives the waste material to detach from the upper cutter roller 2, causing a portion of the waste material to... One part is connected to the needle tip 41, and the other part is connected to the lower cutter roller 3. A portion of the waste material connected to the needle tip 41 slides to the recessed part 42. The recessed part 42 is recessed between the needle tip 41 and the mounting part 43, so the waste material will not become more and more tightly stuck on the waste removal needle 4. The recessed part 42 is used to receive a portion of the waste material. When the upper cutter roller 2 rotates at the seventh preset angle and the lower cutter roller 3 rotates at the eighth preset angle, the lower cutter roller 3 drives the waste removal needle 4 and the waste material connected to the waste removal needle 4 to rotate to the position that matches the scraper 5. The scraper 5 scrapes the waste material off the waste removal needle 4 and the lower cutter roller 3.

[0021] Specifically, the needle tip 41 may include a cone and a first cylinder arranged vertically. The top of the first cylinder is connected to the bottom of the cone, and the diameter of the top surface of the first cylinder is the same as the diameter of the bottom surface of the cone. The recess 42 may be a second cylinder, with its top connected to the bottom of the second cylinder and its bottom connected to the top of the mounting portion 43. The diameter of the top surface of the recess 42 is smaller than the diameter of the bottom surface of the first cylinder, and the diameter of the bottom surface is smaller than the diameter of the top surface of the mounting portion 43. The waste needle 4 passes through the waste material and forms a hole in the waste material. After the waste material enters the needle tip 41 of the waste cleaning needle 4, the hole gradually expands along the needle tip 41. After passing the highest point, it will be left in the recessed part 42. Since there is a certain gap between the hole on the waste material and the waste cleaning needle 4, the waste material is not completely fixed on the waste cleaning needle 4. When the scraper 5 is used to remove the waste material on the waste cleaning needle 4, the scraper 5 can remove the waste material on the waste cleaning needle 4, and then scrape the part of the waste material on the lower cutter roller 3 off the lower cutter roller 3.

[0022] Specifically, the height of the needle tip 41 can be 2mm, the diameter of the top surface of the first cylinder can be 1.4mm, the height of the recess 42 can be 1.2mm, and the diameter of the top surface of the recess 42 can be 1mm.

[0023] Specifically, the upper cutting roller 2 and the lower cutting roller 3 are arranged vertically; the mounting part 43 is connected to the surface of the lower cutting roller 3, and the waste removal needle 4 protrudes from the surface of the lower cutting roller 3; when the upper cutting roller 2 and the lower cutting roller 3 rotate to cut the packaging paper, the rolling cutter rolls and cuts the packaging paper through the gap to form shaped paper and waste, and the waste removal needle 4 peels the waste off the surface of the upper cutting roller 2. This application can be used in conjunction with a printing press for production. The packaging paper coming out of the printing press enters the gap between the upper cutting roller 2 and the lower cutting roller 3. The rotation speed of the upper cutting roller 2 and the lower cutting roller 3 is synchronized with the speed of the packaging paper. The upper cutting roller 2 and the lower cutting roller 3 rotate to cut the packaging paper into shaped paper and waste.
