Description

Technical Field

[0001] The utility model relates to a full-automatic napkin folding machine, in particular to a full-automatic napkin folding machine, belonging to the technical field of full-automatic napkin folding machines. Background Art

[0002] The fully automatic napkin folding machine is a highly efficient and automated mechanical equipment that is mainly used to automatically fold napkins into preset shapes.

[0003] When folding napkins, the paper is placed in the paper feed port, the motor and positioning mechanism are driven to work, and the paper is conveyed to the folding mechanism. The folding mechanism automatically folds the paper into a preset shape, and the control panel drives the conveying mechanism to output the folded paper.

[0004] In the prior art, when outputting paper, the paper moves on the transmission rack, and the driven conveying mechanism pushes the paper to contact the limiting plate and pushes the limiting plate to move. Under the friction between the limiting plate and the transmission rack, the paper is limited. It is limited by its own gravity and friction, and cannot effectively limit the paper, resulting in the paper being loosely connected on the transmission rack and easily scattered, affecting the paper collection and cutting effect. Therefore, we propose a fully automatic napkin folding machine. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] The utility model discloses a fully automatic napkin folding machine.

[0023] According to the attached Figure 1-3 As shown, it includes a napkin folding machine 1, a folding mechanism 2, a cutting mechanism 3 and a support frame 4. The napkin folding machine 1 is provided with the folding mechanism 2 and the cutting mechanism 3. The support frame 4 is fixedly connected to the napkin folding machine 1. Two side baffles 401 are slidably connected to the support frame 4. The cutting mechanism 3 is located directly above the support frame 4. The support frame 4 is transmission-connected with a transmission unit 5 and a limiting unit 6. The paper end on the paper roll passes through the napkin folding machine 1. Under the action of the folding mechanism 2, the paper towel is folded. The folded paper is on the support frame 4. When the paper is transmitted on the support frame 4, the cutting mechanism 3 is cooperated to cut the paper.

[0024] The transmission unit 5 includes a sliding seat 502 slidably connected to the inner wall of the support frame 4, and a limiting unit 6 is connected to the sliding seat 502. The sliding seat 502 is driven by the screw rod 501 to slide on the support frame 4. Under the movement of the sliding seat 502, the limiting unit 6 moves accordingly, and the paper towels on the support frame 4 are limited by the limiting unit 6, thereby ensuring the stability of the cutting mechanism 3 when cutting the paper towels. At the same time, the cut paper is limited for easy removal to prevent the paper from being scattered. At this time, when the paper is continuously transported under the action of the folding mechanism 2, the limiting unit 6 is driven to move under the movement of the screw rod 501, thereby ensuring that the paper is always limited during processing;

[0025] The limiting unit 6 includes a fixed seat 601 fixedly connected to the sliding seat 502, and a threaded rod 603 is slidably connected to the inner wall of the fixed seat 601, and a connecting seat 7 is fixedly connected to one side of the threaded rod 603. A squeezing seat 701 is provided on one side of the connecting seat 7. When the paper towel is transmitted to the supporting frame 4, the sliding seat 502 is driven to move by the transmission unit 5, so that the sliding seat 502 drives the fixed seat 601, the connecting seat 7 and the squeezing seat 701 to move. At this time, the squeezing seat 701 contacts and squeezes the paper towel. At this time, by adjusting the threaded rod 603 and the guide rod 602 to slide along the inner wall of the fixed seat 601, the position of the connecting seat 7 is changed, and then the squeezing of the paper towel by the squeezing seat 701 is changed.

[0026] A screw rod 501 is rotatably connected to the inner wall of the support frame 4 , and the screw rod 501 is threadedly connected to the sliding seat 502 .

[0027] One end of the screw rod 501 is connected to the driving mechanism, which is installed on the bottom end face of the support frame 4. The driving mechanism drives the screw rod 501 to rotate. When the screw rod 501 rotates, the sliding seat 502 rotates along the outer wall of the screw rod 501. At this time, the sliding seat 502 slides along the inner wall of the support frame 4.

[0028] There are multiple guide rods 602 slidingly connected to the inner wall of the fixed seat 601, and one side of the guide rod 602 is fixedly connected to the connecting seat 7. When the sliding seat 502 moves, it drives the fixed seat 601 to move. At this time, the fixed seat 601, the guide rod 602 and the threaded rod 603 move with the sliding seat 502 at the same time, driving the connecting seat 7 to move accordingly.

[0029] A nut seat 604 is rotatably connected to the outer wall of the fixing seat 601 , and the nut seat 604 is threadedly connected to the outer peripheral wall of the threaded rod 603 .

[0030] There are multiple sliding rods 702 slidingly connected to the inner wall of the connecting seat 7, and the other side of the multiple sliding rods 702 is fixedly connected to the extrusion seat 701. When the connecting seat 7 moves, the sliding rods 702 and the extrusion seat 701 move accordingly. When the connecting seat 7 moves, the extrusion seat 701 contacts and squeezes the paper towel. By rotating the nut seat 604, the threaded rod 603 and the guide rod 602 are driven to slide along the inner wall of the fixed seat 601, and the position of the connecting seat 7 is adjusted, the distance between the connecting seat 7 and the extrusion seat 701 is changed, and then the thrust of the spring 703 on the extrusion seat 701 is changed.

[0031] A spring 703 is sleeved on the outer peripheral wall of the sliding rod 702 , and two sides of the spring 703 are fixedly connected to the extrusion seat 701 and the connecting seat 7 respectively.

[0032] The end of the squeezing seat 701 away from the sliding rod 702 is fixedly connected to the limiting block, and the limiting block fits with the connecting seat 7. Under the rebound of the spring 703, the squeezing seat 701 is pushed to squeeze the paper towel, thereby limiting the paper towel on the support frame 4, ensuring the stability of the cutting mechanism 3 when cutting the paper towel, and at the same time limiting the cut paper for easy removal to prevent the paper from scattering.

[0033] At this time, the napkin folding machine 1 is started, and the driving mechanism installed at the bottom of the support frame 4 drives the screw rod 501 to rotate. Under the movement of the sliding seat 502, the limiting unit 6 moves accordingly, and the paper towels on the support frame 4 are limited by the limiting unit 6. At this time, when the paper continues to be transported under the action of the folding mechanism 2, the movement of the screw rod 501 drives the limiting unit 6 to move, ensuring that the paper is always limited during processing.

[0034] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
