Description
1. Technical field
[0002] The utility model belongs to the technical field of packaging carton processing, and particularly relates to a printing press reel hoisting device. (II) Background technology
[0004] Packaging cartons refer to the packaging of products in paper boxes in order to protect products, facilitate storage and transportation, and promote sales during the circulation process. Carton packaging has the characteristics of easy material acquisition, light weight, easy printing, easy design and molding, and low cost, and is widely used in sales packaging and transportation packaging of goods. In order to intuitively understand the products inside the packaging cartons on the surface, and also for publicity, the surface of the packaging cartons needs to be printed with patterns. When mass-producing packaging cartons, it is necessary to use a digital printing machine to print patterns on the paper. Under current technology, paper is usually wound on a roll, unwound into the printing machine, and then rewound after printing. When the diameter of the paper wound on the roll is large, it is time-consuming and labor-intensive to put the unwinding roll of the paper before printing on the printing machine and to remove the fully wound rewinding roll from the printing machine, which is prone to safety accidents, not only causing property losses, but also easily causing personal injuries to operators.

[0009] A crossbeam is installed on the top of the swing arm.
[0010] The hook is hinged to the lower part of the swing block, the upper part of the swing block is hinged to the sprocket, and the sprocket is arranged on the chain.
[0011] A clamping block is installed on the chain.
[0012] The chain passes over the crossbeam.
[0013] An anti-dropping arc plate is arranged above the power gear, and the anti-dropping arc plate is fixed to the bottom of the suspension rod, and the suspension rod is fixed below the crossbeam.
[0014] A chain stopper is installed on the side of the crossbeam.
[0015] The beneficial effects of the utility model are that a larger and heavier unwinding roller can be quickly placed on the roller frame from the ground, and a larger and heavier winding roller can be quickly removed from the roller frame. The operation is convenient, time-saving and labor-saving, safe and reliable, which improves paper printing efficiency and ensures operational safety. (IV) Description of the drawings

(V) Specific implementation methods
[0023] The accompanying drawings are a specific embodiment of the utility model. The embodiment includes a printing machine 1, a roller frame 2 is connected to the rear of the printing machine 1, a reeling roller 3 is installed at the front of the roller frame 2, a reeling roller 4 is installed at the rear of the roller frame 2, the outer side of the roller frame 2 is hinged to the bottom of the swing arm 5, the lower part of the swing arm 5 is hinged to one end of the cylinder 6, the other end of the cylinder 6 is connected to the roller frame 2, a power shaft 7 is installed on the upper part of the swing arm 5, a power gear 8 is installed on the power shaft 7, a chain 9 is wound around the power gear 8, and a hook 10 is connected to the bottom of the chain 9. A crossbeam 11 is installed on the top of the swing arm 5. The hook 10 is hinged to the lower part of the swing block 12, the upper part of the swing block 12 is hinged to the sprocket 13, and the sprocket 13 is arranged on the chain 9. A clamping block 14 is installed on the chain 9. The chain 9 passes over the top of the crossbeam 11. An anti-slip circular arc plate 15 is provided above the power gear 8, and the anti-slip circular arc plate 15 is fixed to the bottom of the suspension rod 16, and the suspension rod 16 is fixed below the crossbeam 11. A chain stopper 17 is installed on the side of the cross beam 11 .
[0024] The utility model of the printing press reeling and unreeling roller hoisting device is adopted, the unreeling roller 3 for winding paper is placed on the ground, the cylinder 6 is started, the piston rod of the cylinder 6 is extended, and the swing arm 5 is pushed to swing backward until the cross beam 11 leaves the roller frame 2, the motor is started to drive the power shaft 7 to rotate through the reducer, the power shaft 7 drives the power gear 8 to rotate synchronously, the power gear 8 drives the chain 9 to be lowered, the hook 10 is hung on both ends of the unreeling roller 3, the motor is started again, the power shaft 7 rotates in the opposite direction, the chain 9 is retracted upward, so that the unreeling roller 3 is raised to a certain height through the hook 10, and then, the cylinder 6 is started, the piston rod of the cylinder 6 is retracted, and the swing arm 5 is pulled forward to swing until the cross beam is located just above the position where the unreeling roller 3 is placed, and the unreeling roller 3 is placed at the required position of the roller frame 2. The paper on the unreeling roller 3 enters the printing press 1, and the paper after printing is finally wound on the reeling roller 4 through the multi-stage roller until the unreeling roller 3 is completely unwound, and all the printed paper is wound on the reeling roller 4. Start the cylinder 6 again, the piston rod of the cylinder 6 extends, pushes the swing arm 5 to swing backward until the crossbeam 11 is located directly above the winding roller 4, puts down the hook 10, and lifts the winding roller 4. The piston rod of the cylinder 6 continues to extend until the crossbeam 11 leaves the roller frame 2, puts down the hook 10, places the winding roller 4 on the ground, and lifts the new unwinding roller 3 again through the hook 10. This cycle repeats to complete the unwinding roller 3 and the unwinding roller 4. The hook 10 is hinged to the lower part of the swing block 12, and the upper part of the swing block 12 is hinged to the sprocket 13. In this way, the hook 10 can rotate relative to the swing block 12, and the swing block 12 can rotate relative to the sprocket 13, which greatly improves the flexibility of the use of the hook 10. The part of the chain 9 connected to the clamp block 14 does not need to rotate, and the clamp block 14 effectively ensures the stability of the chain 9 when it rotates. The chain 9 is wound around the power gear 8. When the chain 9 rotates rapidly, it may be separated from the power gear 8 due to inertia. The anti-separation arc plate 15 is arranged above the power gear 8 to effectively solve this problem. The chain stopper 17 effectively ensures the stability of the chain 9 when it moves up and down.
