DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solution of this application in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0022] The embodiment of the present application discloses a protective mask sheeting machine that is easy to disassemble. Figure 1 、 Figure 2 and Figure 3 The protective mask sheeting machine that is easy to disassemble includes a sheeting machine body 1, on which a knife roller 2 is installed, and a cutter 3 is installed on the knife roller 2. The knife roller 2 includes a roller body 4, and a mounting groove 5 is provided on the outer peripheral surface of the roller body 4 along its length. The mounting groove 5 does not extend through the end of the roller body 4 in the length direction. The roller body 4 is fixed with a mounting seat 6 on the bottom wall of the mounting groove 5, and the cutter 3 is mounted on the mounting seat 6. Specifically, the cutter 3 is fixed to the mounting seat 6 in a bolted manner. The roller body 4 is also provided with a cover plate 7 for covering the mounting groove 5 and a locking device for locking the cover plate 7 to the roller body 4. When the cover plate 7 and the roller body 4 are buckled together, they form a complete cylinder, and a knife groove 8 is reserved at the seam between the two for the cutter head of the cutter 3 to extend. The knife groove 8 is provided on the bottom wall of the mounting groove 5, and when the cutter head of the cutter 3 is embedded in the knife groove 8, the cutting surface of the cutter 3 is flush with the bottom wall of the mounting groove 5.

[0023] After being set up in this way, when the cutter 3 needs to be replaced, there is no need to remove the cutter roller 2. It is only necessary to release the lock of the locking device on the cover plate 7, and then remove the cover plate 7, and then replace the cutter 3 on the mounting seat 6; after the cutter 3 is replaced, the cover plate 7 is covered and locked by the locking device, without removing the transmission structure on the cutter roller 2 or re-calibrating the cutter roller 2, which greatly improves the convenience and efficiency of replacing the cutter 3.

[0024] When setting up the specific Figure 3 and Figure 4 The locking device includes a card embedding structure for realizing the card embedding connection between the cover plate 7 and the roller body 4 and a fixing mechanism for fixing the cover plate 7 on the roller body 4; wherein the card embedding structure includes a plurality of card strips 9 fixedly connected to one side of the length direction of the cover plate 7 and a plurality of slots 10 opened on the roller body 4, a plurality of card strips 9 and a plurality of slots 10 are arranged in a one-to-one correspondence and the card strips 9 are fixedly connected to one side of the inner arc surface of the cover plate 7, and the card strips 9 and the slots 10 are gap-fitted and adapted; the roller body 4 is also fixedly connected to a support strip 11 on the groove wall of the mounting groove 5. When the cover plate 7 completely covers the mounting groove 5, the inner arc side of the cover plate 7 away from the end of the card strip 9 rests on the support strip 11. The support strip 11 can be arranged along the length direction of the roller body 4, or it can be arranged in a plurality and arranged at equal intervals along the length direction of the roller body 4.

[0025] After such arrangement, after replacing the cutter 3, first insert the multiple clips 9 on the cover plate 7 into the multiple slots 10 on the multiple roller bodies 4 one by one, and then flip the cover plate 7 until the inner arc side of the cover plate 7 rests on the support strip 11. At this time, the cover plate 7 can completely close the mounting groove 5 on the roller body 4.

[0026] In order to reduce the probability of the cover plate 7 shaking during the high-speed rotation of the knife roller 2, refer to Figure 3 and Figure 4 An elastic layer 12 is provided between the support strip 11 and the cover plate 7, and when the outer peripheral wall of the cover plate 7 is flush with the outer peripheral wall of the roller body 4, the elastic layer 12 is compressed and deformed; wherein the elastic layer 12 is set as a rubber sheet, and the elastic layer 12 can be fixed to the support strip 11 or to the cover plate 7.

[0027] In this way, when the fixing mechanism fixes the cover plate 7 on the roller body 4, the compressed elastic layer 12 tightly fills the gap between the cover plate 7 and the roller body 4, making the connection between the cover plate 7 and the roller body 4 tighter, greatly reducing the possibility of the cover plate 7 shaking on the roller body 4.

[0028] In order to realize the convenient fixing of the cover plate 7 on the roller body 4, refer to Figure 3 and Figure 4The fixing mechanism includes two fixing hooks 13 respectively fixed to the two ends of the cover plate 7 in the length direction, and a fixing bolt 14 is threadedly connected to the end of the roller body 4; when the cover plate 7 completely covers the mounting groove 5, the fixing bolt 14 is aligned with the hook portion of the fixing hook 13; and, a reduced diameter portion 15 is provided at one end of the fixing bolt 14 close to the middle of the roller body 4, and the outer diameter of the reduced diameter portion 15 gradually decreases along the direction from the end of the roller body 4 to the middle of the roller body 4.

[0029] After such arrangement, after flipping over the cover plate 7 to cover the mounting groove 5, the fixing bolt 14 is rotated, and the fixing bolt 14 passes through the bent hook portion of the fixing hook 13, which can pull and limit the fixing hook 13 and the cover plate 7 so that the cover plate 7 is tightly pressed against the roller body 4; and since the fixing bolt 14 is also provided with a reduced diameter portion 15, as the fixing bolt 14 gradually extends into the mounting groove 5, the fixing bolt 14 pushes the fixing hook 13 toward the middle of the roller body 4. The greater the stroke, the tighter the elastic layer 12 can be pressed, that is, the cover plate 7 is more securely installed on the roller body 4.

[0030] The implementation principle of the protective mask sheeting machine that is easy to disassemble in the embodiment of the present application is: when the cutter 3 needs to be replaced, there is no need to remove the knife roller 2, only the locking device for the cover plate 7 needs to be released, and then the cover plate 7 is removed, and then the cutter 3 is replaced on the mounting seat 6; after the cutter 3 is replaced, the cover plate 7 is covered and locked by the locking device, and there is no need to remove the transmission structure on the knife roller 2, nor is there any need to recalibrate the knife roller 2, which greatly improves the convenience and efficiency of replacing the cutter 3.

[0031] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
