[0025] The manual lifting of woven bag rolls requires a high level of manual coordination. Different lifting heights will cause the woven bag rolls to tilt or even fall, which poses a certain safety hazard. Figures 1 to 4As shown, a material roll winding mechanism of a printing press comprises a base 1, and fixed seats 6 are respectively vertically installed on the left and right sides of the top of the base 1, a rotating rod 7 is rotatably connected between the outer walls of the two fixed seats 6 through bearings, and lifting components are respectively installed on the left and right sides of the outer wall of the rotating rod 7, and the free end of the rotating rod 7 extends into the inner cavity of the fixed seat 6 and is rotatably connected to the inner wall of the fixed seat 6 through bearings, and gears 8 are respectively installed at the two free ends of the rotating rod 7, and the bottom ends of the outer walls of the two gears 8 are respectively meshed and connected with racks 5, and by driving the racks 5 to move, the gears 8 can be driven to rotate to realize the rotation of the rotating rod 7, and the two racks 5 can respectively realize the movement in the front and rear directions through the driving components, and the racks 5 can be moved and locked after the movement through the driving components.

[0026] See also Figure 4 As shown, the driving component includes a slide groove 2 opened on the upper surface of the base 1 from front to back, and also includes a screw 3 connected to the inner cavity of the base 1 through a bearing from front to back, and a moving seat 4 is provided on the outer wall of the screw 3 through a threaded sleeve, and the moving seat 4 is slidably embedded in the inner cavity of the slide groove 2, and the top of the moving seat 4 is connected to the bottom end of the outer wall of the rack 5. When an external force drives the screw 3 to rotate, it can drive the moving seat 4 to move along the inner cavity of the slide groove 2, and then drive the rack 5 to move, and through the threaded cooperation between the screw 3 and the moving seat 4, the moving seat 4 can be locked after the moving position, and the screw 3 is driven to continue to rotate.

[0027] In order to achieve the synchronous rotation of the two screws 3, a pulley 12 is installed on the front side of the outer wall of the screw 3, and a belt 13 is provided on the sliding sleeve of the outer wall of the pulley 12. A motor 14 is installed on the front side wall of the base 1, and the output end of the motor 14 is connected to the left screw 3. The turned-on motor 14 drives the left screw 3 connected to its output end to rotate, thereby driving the pulley 12 on the outer wall of the left screw 3 to rotate synchronously. The pulley 12 drives the belt 13 set on the outer wall to rotate, so as to drive the pulley 12 on the right side to rotate synchronously. As a result, the left and right pulleys 12 respectively drive the left and right screws 3 to rotate synchronously and in the same direction.

[0028] The lifting component includes a rotating arm 15 installed on the outer wall of the rotating rod 7, a cylinder 16 is installed in the inner cavity of the rotating arm 15, a supporting seat 17 is installed at the output end of the cylinder 16, and a placement groove 18 is opened on the outer wall of the supporting seat 17. Through the telescopic setting of the output end of the cylinder 1, the supporting seat 17 can be driven to adjust the position to adapt to the embedded connection of different material rolls at the supporting seat 17.

[0029] See also Figure 4As shown, an auxiliary limiting component is provided on the side opposite to the outer wall of the rotating arm 15 and the fixed seat 6, the auxiliary limiting component includes a connecting rod 10 installed on the outer wall of the rotating rod 7, and a movable pin 11 is installed on the outer wall of the connecting rod 10. The auxiliary limiting component includes a limiting groove 9 opened on the side wall of the fixed seat 6, and the movable pin 11 is slidably embedded in the inner cavity of the limiting groove 9. When the rotating rod 7 rotates, it can drive the rotating arm 15 and the connecting rod 10 to rotate synchronously with the axis of the rotating rod 7. At this time, the movable pin 11 at the end of the connecting rod 10 can move along the inner cavity of the limiting groove 10 to assist in limiting the rotation of the rotating arm 15 and prevent the rotating arm 15 from rotating and tilting; wherein, the center point of the limiting groove 9 is located on the central axis of the rotating rod 7, thereby ensuring that when the movable pin 11 moves along the inner cavity of the limiting groove 9, there will be no interference, and it can move smoothly along the inner cavity of the limiting groove 9.

[0030] See also Figure 2-Figure 4 As shown, a material roller 19 is embedded in the inner cavity of the placement groove 18, a stopper 20 is installed at one end of the material roller 19, and a material roll 21 is installed at the other end of the material roller 19, and the stopper 20 is arranged on the outer side of the outer wall of the support seat 17, and the material roll 21 is arranged on the inner side of the outer wall of the support seat 17, and the material rollers 19 at both ends of the material roll 21 are placed in the corresponding inner cavities of the placement groove 18 to achieve preliminary installation of both ends of the material roll 21 at the two support seats 17. In order to achieve stable placement of the material roller 19 in the inner cavity of the support seat 17, the radius of the stopper 20 is larger than the radius of the placement groove 18, so that the material roller 19 is prevented from escaping from the inner cavity of the placement groove 18 on the outer wall of the support seat 17 under the blocking action of the stopper 20.

[0031] In order to facilitate the movement of the entire device, universal wheels 22 are respectively installed at the four corners of the bottom end of the base 1. Through the arrangement of the universal wheels 22, the device can be flexibly transported, thereby meeting the use of the entire device in different occasions.

[0032] The working principle of the material roll-up mechanism of a printing press in this embodiment is as follows:

[0033] Place the material roll 21 on the ground. In the initial state, the two cylinders 16 are made horizontal. The material rollers 19 at both ends of the material roll 21 are placed in the corresponding inner cavities of the placement grooves 18 to achieve the initial placement of the two ends of the material roll 21 at the two supporting seats 17.

[0034] The motor 14 is turned on to drive the left lead screw 3 connected to its output end to rotate, thereby driving the pulley 12 on the outer wall of the left lead screw 3 to rotate synchronously, and the pulley 12 drives the belt 13 sleeved on the outer wall to rotate, so as to drive the pulley 12 on the right to rotate synchronously, thereby the left and right pulleys 12 respectively drive the left and right lead screws 3 to rotate synchronously and in the same direction;

[0035] The rotating lead screw 3 causes the moving seat 4 of the outer wall to move backward along the inner cavity of the slide slot 2, thereby driving the rack 5 to move backward, and the rack 5 drives the gear 8 meshing with its outer wall to rotate forward, thereby driving the rotating rod 7, the rotating arm 15, and the cylinder 16 to rotate forward synchronously. At this time, the material roll 21 positioned at the supporting seat 17 connected to the output end of the cylinder 16 gradually rotates forward to be lifted along with the rotating arm 15, causing the material roll 21 to be gradually lifted off the ground, and the material roll 21 is lifted to the loading position of the printing press for installation and assembly of the material roll 21; because the rotating arms 15 on the left and right sides drive the supporting seat 17 to act synchronously, thereby driving the two free ends of the material roll 21 to be lifted synchronously, thereby ensuring stability and safety during the lifting process;

[0036] The two ends of the material roll 21 of the utility model can be stably and synchronously lifted, which is more stable than the lifting method of multiple people cooperating, and eliminates the situation that the material roll 21 may fall over due to asynchronous manual cooperation, eliminates the safety hazard caused by the falling over of the material roll 21, and the lifting and installation of the material roll 21 is more labor-saving and convenient than manual work. In addition, the lifting angle of the material roll can be adapted to the material roll installation position of printing machines in different occasions, and the equipment has a wide range of uses.

For those skilled in the art, the utility model can have various modifications and changes.
