Description

Technical Field

[0001] The utility model relates to the technical field of mask machines, in particular to a cutting mechanism of a mask machine. Background Art

[0002] The mask machine uses processes such as hot pressing, folding, ultrasonic welding, waste cutting, ear strap and nose bridge welding to manufacture various masks with certain filtering performance through multi-layer non-woven fabrics. The mask equipment is not a single machine, it requires the cooperation of multiple machines to complete various processes. The more popular mask equipment on the market include; cup-shaped mask machine, non-woven flat mask machine, N95 mask machine, 3M9001 / 9002 folding mouth-placement machine, duckbill mouth-placement machine, three-dimensional dust-proof mouth-placement machine, etc.

[0003] After the mask machine hot-presses the non-woven fabric, it will be cut by a cutter. The existing cutter generally has a cutter groove on the cutter roller, and then the cutter is locked with screws from the side of the cutter roller to fix the cutter. For example, the Chinese utility model patent with application number "202011040314.6" discloses a cutter wheel for a mask machine, and its cutter is directly set on the cutter roller. However, during long-term use, dust and other debris will adhere to the cutter groove, causing the cutter to be fixed on it. When replacing the cutter, it is difficult to take out the cutter after loosening the screws on the side.

[0004] To this end, the utility model proposes a mask machine cutting mechanism to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figures 1 to 4 In the embodiment of the utility model, the cutting mechanism of the mask machine includes a support table 1, on which a pair of support plates 2 are arranged at intervals, a lower cutting knife roller 3 is arranged between the lower parts of the support plates 2, and the two ends of the lower cutting knife roller 3 are rotatably connected to the corresponding support plates 2 respectively, and an upper cutting knife roller 4 cooperating with the lower cutting knife roller 3 is arranged between the upper parts of the support plates 2, and a fan-shaped groove 5 is arranged on the upper cutting knife roller 4, in which a cutting knife 6 is arranged, and a clamping block 7 matching its shape for clamping the cutting knife 6 is detachably provided at the groove 5. By arranging the clamping block 7 in a detachable manner, the cutting knife 6 can be easily replaced to prevent the cutting knife 6 from being inconvenient to be removed due to dust accumulation inside after being used for a long time. At the same time, the installation can also be more convenient, and it is easier to install the cutting knife 6 in place to prevent it from being directly plugged into the knife groove, resulting in the problem of inadequate installation.

[0022] Furthermore, a plurality of through holes 8 are provided at the lower portion of the cutter 6, and a plurality of locking holes corresponding to the through holes 8 are provided on the clamping block 7. The through holes 8 are provided with screws which pass through the through holes 8 and are locked into the side surfaces of the grooves 5. It should be noted that after the screws are locked into the locking holes, the outer ends of the screws do not protrude from the locking holes to prevent the screw ends from pressing on the material strip.

[0023] Furthermore, a plurality of positioning posts 9 are provided at the bottom of the cutter 6, and a plurality of positioning holes 10 corresponding to the positioning posts 9 are provided on the groove 5. The cutter 6 can be quickly positioned through the cooperation between the positioning posts 9 and the positioning holes 10. It should also be noted that the positioning holes 10 need to be slightly larger than the positioning posts 9, so that it is easy to install. At the same time, when the clamping block 7 clamps the lower part of the cutter 6, it can prevent the positioning posts 9 from being deformed by force, which makes it difficult to pull out later.

[0024] Furthermore, both ends of the upper cutting roller 4 are provided with sliding frames 11 rotatably connected thereto, and the support plate 2 is provided with sliding grooves 12 for sliding up and down cooperation with the sliding frame 11, and the top of the sliding groove 12 is provided with a locking bolt 13. By setting the sliding frame 11 and pressing the sliding frame 11 with the locking bolt 13, the lower cutting roller 3 can be fixed.

[0025] Furthermore, a bearing 14 is provided in the sliding frame 11 , and both ends of the upper cutting roller 4 are rotatably connected to the bearing 14 .

[0026] Furthermore, the same end of the upper cutting roller 4 and the lower cutting roller 3 passes through the bearing 14, and an upper gear 15 is provided at one end of the upper cutting roller 4 passing through the bearing 14, and a double-row gear 16 matching with the upper gear 15 is provided at one end of the lower cutting roller 3 passing through the bearing 14. One row of the double-row gears 16 cooperates with an external chain or other gears to drive it to rotate, and then the upper gear 15 can be driven to rotate, so that the upper cutting roller 4 and the lower cutting roller 3 can rotate synchronously to drive the material belt to move.

[0027] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
