[0019] Embodiment: A paper cutting mechanism: See Figure 1 As shown:
[0020] The paper cutting mechanism 1 comprises an adsorption table 11, a fixed clamping jaw mechanism 12, a movable clamping jaw mechanism 13 and a cutter 14. The adsorption table 11 is a table with vacuum adsorption holes. The fixed clamping jaw mechanism 12 and the movable clamping jaw mechanism 13 are respectively arranged on opposite sides of the adsorption table 11. The fixed clamping jaw mechanism 12 is composed of at least one pair of fixed clamping bars 121 opposite to each other up and down (two are shown in the figure, one up and one down) and a fixed clamping module 122; the movable clamping jaw mechanism 13 is composed of at least one pair of movable clamping bars 131 opposite to each other up and down, a movable clamping module 132 and a translation module 133. The translation module 133 drives the movable clamping bars 131 and the movable clamping module 132 to move closer to or away from the fixed clamping jaw mechanism 12 in the horizontal direction to complete the paper pulling action; the cutter 14 is arranged on the side of the adsorption table 11 where the fixed clamping bars 121 are arranged, and is located on the inner side relative to the fixed clamping bars 121 to complete the paper cutting action.
[0021] See also Figure 1 As shown, the fixed clamping bar 121 has a plurality of grooves 1211 arranged at intervals on the side facing the adsorption table 11, and the movable clamping bar 131 has a plurality of protrusions 1311 correspondingly protruding on the side facing the adsorption table 11. When the movable clamping bar 131 is close to the fixed clamping bar 121, the protrusions 1311 of the movable clamping bar 131 extend into the grooves 1211 of the fixed clamping bar 121 to clamp the paper.
[0022] Further, see Figure 1 As shown, the cutter 14 is a disc knife structure, specifically including a circular cutter disc 141, a cutter disc lifting module 142 and a cutter disc translation module 143. The circular cutter disc 141 is rotatably supported and, under the action of the cutter disc lifting module 142 and the cutter disc translation module 143, translates and rotates along the length direction of the fixed clamp strip 121 for cutting.
[0023] Further, see Figure 1 As shown, the paper cutting mechanism 1 also includes a lower supporting assembly 15, which is correspondingly arranged under the cutter 14 and cooperates with the cutter. Specifically, the lower supporting assembly 15 includes a lower supporting bar 151 and a lower supporting bar lifting module 152, so that the lower supporting bar 151 is lifted into place to cooperate with the cutter 14 for cutting during cutting, and the lower supporting bar 151 is lowered to avoid cutting when not cutting.
[0024] The movable clamping strip 131 is provided with an elastic floating body, which is clamped by the resistance effect of the elastic floating body.
[0025] Before starting up, first pull out the end of the paper (usually tissue paper) from the paper roll and thread it through the fixed clamping strips 121. Operate the fixed clamping strips 121 to close and clamp the paper, thus completing the paper loading preparation work.
[0026] After starting up, first, the movable clamping strip 131 of the movable jaw mechanism 13 completes a reciprocating displacement to pull out the paper and spread it over the adsorption table 11. Then, after the lower supporting strip 151 of the upper supporting component 15 is lifted in place, the cutting knife 14 drops to complete the cutting, and an independent sheet of paper is fixed on the adsorption table 11 for use.
[0027] The fixed clamping module 122, the movable clamping module 132, the translation module 133, the cutter head lifting module 142, the cutter head translation module 143, and the lower supporting strip lifting module 152 can adopt driving devices such as air cylinders or motors, with air cylinders being preferred.
