Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and more specifically, to a printing press feeding device. Background Technology

[0002] Printing presses, as one of the most common printing equipment in the printing industry, are capable of mass printing of paper. When printing paper in batches, the paper is usually wound around a paper tube, and then the paper tube is placed on a feeding device, which then feeds the paper smoothly into the printing press.

[0003] Publication No. CN221439833U discloses a rapid feeding device for a printing machine. The technical solution includes two side plates fixedly connected to the top edge of a base plate. The two side plates are located on the front and back of the top left end of the base plate. A motor is fixedly connected to the front of the front side plate. The output shaft of the motor is fixedly connected to one end of a double-ended screw. The two ends of the double-ended screw are rotatably connected to the two side plates respectively. The double-ended screw passes through a moving block and is threadedly connected to the moving block. The two moving blocks are located on the threaded portions on both sides of the double-ended screw. A mounting plate is fixedly connected to the top of the moving block. Two slide rails are fixedly connected to the top of the base plate. The two slide rails are located on the left and right sides of the bottom of the mounting plate.

[0004] When the above-mentioned technical solution uses the feeding device to feed paper, the electric drive causes the bidirectional screw to rotate. At the same time, the bidirectional screw drives the two mounting plates to move towards the printing paper roll and install them together with the printing paper roll, thereby achieving the effect of feeding paper. When it is necessary to replace the printing paper roll, simply drive the motor to rotate in the opposite direction to separate the mounting plates from the printing paper roll. Then repeat the above operation to install another printing paper roll with the mounting plate, thereby completing the effect of replacing the printing paper roll.

[0005] However, when changing the printing paper roll, the above technical solution requires the operator to lift the printing paper roll upwards and place it between two mounting plates before the printing paper roll can be fixed. When the operator lifts the printing paper roll, the paper will affect the weight of the printing paper roll, which will increase the weight of the printing paper roll. As a result, the operator will need to exert more force to lift the printing paper roll, which will affect the work efficiency.

[0006] Therefore, a new solution is needed to address this problem. Utility Model Content

[0007] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a printing press feeding device that solves the problem that when changing printing paper rolls, the weight of the paper affects the operator's ability to lift the rolls, resulting in significant effort and reduced work efficiency.

[0008] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a printing machine feeding device, comprising a device body, a support frame fixedly connected to the side wall of the device body, a slide groove provided on the side wall of the support frame, a movable block slidably connected in the slide groove, a lifting component provided on the support frame for driving the movable block to move along the slide groove, a slide rail for sliding the printing paper roll fixedly connected to the side of the support frame away from the device body, one end of the slide rail contacting the ground, the other end penetrating into the slide groove, a push plate slidably connected to the slide rail, an electric push rod fixedly connected to the side of the slide rail away from the support frame, and the output end of the electric push rod fixedly connected to the push plate.

[0009] By adopting the above technical solution, when it is necessary to replace the printing paper roll, the printing paper roll located in the support frame is taken out. Then, the printing paper roll with paper is pushed to move between the two slide rails and make contact with the slide rails. Then, the electric push rod is activated, and the output end of the electric push rod drives the push plate to move along the slide groove. At the same time, the push plate pushes the printing paper roll with paper towards the support frame. Since the support frame and the slide rails are interconnected, when the printing paper roll with paper moves to the support frame, the printing paper roll with paper will enter the support frame and make contact with the moving block inside the support frame. Then, the lifting component drives the moving block to move upward and lifts the printing paper roll with paper upward. This achieves the effect of automatically lifting the printing paper roll with paper, reducing the effort required by the staff when replacing the printing paper roll and improving work efficiency.

[0010] The present invention is further configured such that: the lifting assembly includes a connecting block fixedly connected to one side of the moving block; the side wall of the support frame is provided with a through groove for the connecting block to slide; a motor is fixedly connected to the support frame; a screw is fixedly connected to the output end of the motor; and the screw passes through the connecting block and is threadedly connected to the connecting block.

[0011] By adopting the above technical solution, when driving the moving block to move along the slide, the motor is started, and the output end of the motor drives the screw to rotate. At the same time, the screw drives the connecting block to move along the through groove, and drives the moving block to move in the same direction along the slide, thereby achieving the effect of driving the moving block to move along the slide.

[0012] The present invention is further configured such that: a limiting plate is fixedly connected to the top of the support frame, and a limiting groove for the screw to rotate is provided at the bottom of the limiting plate.

[0013] By adopting the above technical solution, when the connecting block moves along the through groove, the setting of the limiting plate can limit the connecting block, preventing the connecting block and the screw from separating. When the printing paper roll with paper is placed on the moving block, the weight of the printing paper roll with paper will be converted into pressure on the moving block, connecting block and screw. At this time, the setting of the limiting groove can support the screw, prevent the screw from tilting due to pressure, and improve the stability of the screw.

[0014] The present invention is further configured such that an opening is provided at the top of the support frame.

[0015] By adopting the above technical solution, it is easier for staff to remove the used printing paper rolls from the support frame, making it easier for staff to operate.

[0016] The present invention is further configured such that: the movable block has a groove for placing the printing paper roll.

[0017] By adopting the above technical solution, the fixing effect between the printing paper roll and the moving block can be improved, and the stability of the printing paper roll on the moving block can be increased.

[0018] The present invention is further configured such that the slide rail is inclined toward the support frame.

[0019] By adopting the above technical solution, when the printing paper roll with paper is pushed to the slide rail, it is easy to put the printing paper roll at different positions into the slide rail, thereby making it easier to drive the pusher plate to move the printing paper roll along the slide rail.

[0020] In summary, this utility model has the following beneficial effects: When it is necessary to replace the printing paper roll, the printing paper roll is pushed between the two slide rails and comes into contact with the slide rails. Then, the output end of the electric push rod drives the push plate to move along the slide groove. At the same time, the push plate pushes the printing paper roll towards the support frame, causing the printing paper roll to enter the support frame and come into contact with the moving block inside the support frame. Then, the lifting component drives the moving block to move upward and lifts the printing paper roll with paper on it. This achieves the effect of automatically lifting the printing paper roll with paper on it, reducing the effort required by the staff when replacing the printing paper roll and improving work efficiency.

[0028] A printing press feeding device, such as Figures 1-3As shown, the device includes a main body 1 with a printing paper roll. A support frame 2 is fixedly connected to the side wall of the main body 1. A groove 3 is provided on the side wall of the support frame 2, and a movable block 4 is slidably connected in the groove 3. A groove 15 is provided on the movable block 4 for placing the printing paper roll, which can improve the fixing effect between the printing paper roll and the movable block 4 and increase the stability of the printing paper roll on the movable block 4. The support frame 2 is provided with a lifting component for driving the movable block 4 to move along the groove 3. An opening 14 is provided at the top of the support frame 2 to facilitate the removal of the used printing paper roll from the support frame 2, which is convenient for the operator. In operation, a slide rail 5 for sliding the printing paper roll is fixedly connected to the side of the support frame 2 away from the device body 1. One end of the slide rail 5 is in contact with the ground, and the other end passes through the slide groove 3. A push plate 6 is slidably connected to the slide rail 5. An electric push rod 7 is fixedly connected to the side of the slide rail 5 away from the support frame 2. The output end of the electric push rod 7 is fixedly connected to the push plate 6. The slide rail 5 is inclined towards the support frame 2, which makes it easy to push the printing paper roll with paper into the slide rail 5 when it is pushed towards the slide rail 5, so as to drive the push plate 6 to push the printing paper roll along the slide rail 5.

[0029] When it is necessary to replace the printing paper roll, the printing paper roll located in the support frame 2 is taken out through the opening 14. Then, the printing paper roll with paper is pushed to move it between the two slide rails 5 and into contact with the slide rails 5. Then, the electric push rod 7 is activated. The output end of the electric push rod 7 drives the push plate 6 to move along the slide groove 3. At the same time, the push plate 6 pushes the printing paper roll with paper towards the support frame 2. Since the support frame 2 and the slide rails 5 are interconnected, when the printing paper roll with paper moves to the support frame 2, the printing paper roll with paper will enter the support frame 2 and come into contact with the moving block 4 in the support frame 2. Then, the lifting component drives the moving block 4 to move upward and lifts the printing paper roll with paper upward. This achieves the effect of automatically lifting the printing paper roll with paper, reducing the effort required by the staff when replacing the printing paper roll and improving work efficiency.

[0030] like Figures 1-3As shown, the lifting assembly includes a connecting block 8 fixedly connected to one side of the movable block 4. A through groove 9 is provided on the side wall of the support frame 2 for the connecting block 8 to slide. A motor 10 is fixedly connected to the support frame 2. A screw 11 is fixedly connected to the output end of the motor 10. The screw 11 passes through the connecting block 8 and is threadedly connected to it. When the movable block 4 is driven to move along the slide groove 3, the motor 10 is started, and the output end of the motor 10 drives the screw 11 to rotate. Simultaneously, the screw 11 drives the connecting block 8 to move along the through groove 9, and drives the movable block 4 to move in the same direction along the slide groove 3, thereby achieving the effect of driving the movable block 4 to move along the slide groove 3. A limiting plate 12 is fixedly connected to the top, and a limiting groove 13 is provided at the bottom of the limiting plate 12 for the screw 11 to rotate. When the connecting block 8 moves along the through groove 9, the limiting plate 12 can limit the connecting block 8, preventing the connecting block 8 and the screw 11 from separating. When the printing paper roll with paper is placed on the moving block 4, the weight of the printing paper roll with paper will be converted into pressure on the moving block 4, the connecting block 8, and the screw 11. At this time, the limiting groove 13 can support the screw 11, preventing the screw 11 from tilting due to pressure and improving the stability of the screw 11.

[0031] The usage process of this utility model is as follows: When it is necessary to replace the printing paper roll, the printing paper roll located in the support frame 2 is taken out through the opening 14. Then, the printing paper roll with paper is pushed to move it between the two slide rails 5 and into contact with them. Then, the electric push rod 7 is activated. The output end of the electric push rod 7 drives the push plate 6 to move along the slide groove 3. At the same time, the push plate 6 pushes the printing paper roll with paper towards the support frame 2. Since the support frame 2 and the slide rails 5 are interconnected, when the printing paper roll with paper moves... When the paper roll with paper is moved to the support frame 2, it will enter the support frame 2 and come into contact with the moving block 4 inside the support frame 2. Then the motor 10 is started, and the output end of the motor 10 drives the screw 11 to rotate. At the same time, the screw 11 drives the connecting block 8 to move along the through groove 9, and drives the moving block 4 to move upward along the slide groove 3, lifting the paper roll with paper upward. This achieves the effect of automatically lifting the paper roll with paper upward, reducing the effort required by the staff when changing the paper roll and improving work efficiency.
