[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] like Figure 1 to Figure 2 As shown, a mechanical paper unloading mechanism for a digital printing device proposed in this embodiment includes two brackets 601, support plates 602 respectively fixedly connected to the two brackets 601, U-shaped support sleeves 603 respectively fixedly connected to the sides close to the two support plates 602, and a paper reel 6 movably mounted in the two U-shaped support sleeves 603. A mechanical paper unloading mechanism body matching the paper reel 6 is installed on the top of the two brackets 601. The mechanical paper unloading mechanism body includes two cylinders 1, which are respectively fixedly mounted on the top of the corresponding brackets 601. The top of the output shafts of the two cylinders 1 is rotatably mounted with a same lifting link 3, wherein a spherical bearing 2 is fixedly connected to the top of the extended end of the cylinder 1, and the inner ring of the spherical bearing 2 is fixedly fitted to the outer side of the end of the lifting link 3, so as to achieve the effect of rotatably mounting the lifting link 3. Two connecting plates 5 are fixedly connected to the outer side of the lifting link 3, and the left sides of the two connecting plates 5 are clamped with a same driving shaft 4;

[0019] Two support platforms 7 are rotatably sleeved on the driving shaft 4, and a circular sleeve is fixedly connected between the left sides of the two support platforms 7 that are close to each other. The circular sleeve is movably sleeved on the driving shaft 4, and the circular sleeve is used to strengthen the integrity of the two support platforms 7. The right sides of the two support platforms 7 are rotatably installed with the same paper traction rack 9, wherein the right sides of the two support platforms 7 that are close to each other are fixedly connected with the same connecting rod 701, and two hinges 8 are fixedly connected between the top of the connecting rod 701 and the top of the paper traction rack 9, and the support platform 7 is rotatably connected to the paper traction rack 9 through the connecting rod 701 and the hinge 8, which plays an effect of rotatably installing the support platform 7. As a result, the paper-drawing rack 9 is movably clamped on the top of the two brackets 601, the bracket platform 7 is an arc-shaped rod structure with a concave arc at the top, the top of the paper-drawing rack 9 is a V-shaped structure, the bottom front side and the bottom rear side of the paper-drawing rack 9 are fixedly connected with a support, the top right side of the bracket 601 is fixedly connected with a support, the top of the support is movably contacted with the bottom of the corresponding support, the front and rear sides of the paper-drawing rack 9 are fixedly connected with limit plates, the sides of the two limit plates close to each other are movably contacted with the sides of the two supports that repel each other, and the two limit plates are used to perform limiting work on the front and rear sides through the two supports to prevent the paper-drawing rack 9 from shifting forward and backward;

[0020] A round through hole is provided on the left side of the front side of the bracket platform 7, and a support bearing is fixedly sleeved in the round through hole. The inner ring of the support bearing is fixedly sleeved on the outer side of the driving shaft 4, which plays the effect of rotatably installing the driving shaft 4; three hook-shaped slots with openings on the front and rear sides are provided on the left side of the connecting plate 5, and the driving shaft 4 is movably mounted in the two hook-shaped slots at the top. The hook-shaped slots and the driving shaft 4 are movably mounted, which facilitates the upward rotation of the connecting plate 5 and the separation of the driving shaft 4, so as not to affect the subsequent rightward movement of the paper towing rack 9 through the bracket platform 7 to drive the rightward movement of the driving shaft 4.

[0021] The method of using this embodiment is as follows: when unloading the paper rolled up on the paper winding shaft 6, the two cylinders 1 are started in the positive direction, and the two cylinders 1 drive the lifting connecting rod 3 to rise through the two joint bearings 2. The lifting connecting rod 3 drives the driving shaft 4 to move up through the two connecting plates 5, and the driving shaft 4 drives the support platform 7 to rotate upward. At this time, the two support platforms 7 hold the paper winding shaft 6 and the paper rolled thereon and rise out of the notch of the U-shaped support sleeve 603. Since the support platform 7 is inclined at this time and its top is an arc-shaped design, the paper winding shaft 6 slides down along the arc of the support platform 7 to the paper traction rack 9. The support platform 7 and the paper traction rack 9 are connected by hinges 8, which is conducive to up and down rotation. By adopting the principle design of the cylinder 1 to push the lever, the method of pushing and moving and tilting the guide row into the paper traction rack 9 can be adjusted by a single person to achieve the effect of automatic and fast paper unloading, reduce the labor intensity and production cost, and improve the work efficiency and the degree of automation.
