Description

Technical Field

[0001] This utility model relates to the field of printing press technology, specifically an automatic feeding device for a printing press. Background Technology

[0002] An automatic cardboard feeding structure is a device that transports cardboard to the printing press position. A printing press is a machine that prints text and images. The printing press first makes a printing plate of the text and images to be printed, loads it onto the printing press, and then applies ink to the areas of the printing plate with text and images by hand or by the printing press. The ink is then directly or indirectly transferred to the cardboard, thus reproducing a printed product identical to the printing plate.

[0003] Currently, most paper mills still use the traditional manual feeding method for printing. This involves manually moving stacks of cardboard to the vicinity of the ink printing machine, then manually placing each piece onto the conveyor belt and feeding it into the printing machine. This operation is cumbersome, mainly because moving thicker cardboard consumes a lot of labor and requires long hours of manual monitoring, resulting in a significant waste of manpower. Furthermore, it is difficult to adjust the spacing between adjacent cardboard pieces entering the printing machine to be equal, making it impossible to effectively and automatically feed the cardboard into the printing machine.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0009] A clamping structure is located on the top of opposite sides of the two support plates.

[0010] Furthermore, the feeding structure includes a reciprocating screw, a movable seat, a synchronous transmission wheel, and a feeding frame. Movable seats are fixedly connected to the bottom two sides of the feeding frame. Reciprocating screws are respectively installed inside the two movable seats. One end of each of the two reciprocating screws is connected to the inner wall of the cavity by a bearing, and the other end passes through the support platform and is sleeved with a synchronous transmission wheel.

[0011] Furthermore, the two movable seats are slidably connected to the cavity, and the interior of the two movable seats is provided with threaded holes. The two threaded holes are respectively threadedly connected to the reciprocating screw. The two synchronous transmission wheels are connected by a synchronous transmission belt. The end of one of the reciprocating screws away from the storage box is fixedly connected to a drive motor.

[0012] Furthermore, sliders are fixedly connected to both sides of the two lifting seats, the two lifting seats are slidably connected to the inside of the cavity, the two sliders are adapted to the slide groove, one end of the two damping rods is fixedly connected to the inner wall of the cavity, and the other end is fixedly connected to the lifting seat, and buffer springs are sleeved on the outer walls of the two damping rods respectively.

[0013] Furthermore, the top of each of the two support plates is provided with a through cavity, and the two through cavities are provided with sliding grooves on both sides. The bottom of the storage box is provided with through holes on both sides. A control panel is fixedly connected to the front of the storage box.

[0016] The advantages of this invention compared to existing technologies are as follows:

[0017] 1. This utility model provides an automatic feeding device for a printing machine, which is equipped with a feeding structure. Through the cooperation of a drive motor, a synchronous transmission wheel and a synchronous transmission belt, two reciprocating lead screws can rotate simultaneously in the same direction, pushing the moving seat to reciprocate inside the cavity. This drives the feeding frame to stably push the cardboard to feed in an orderly manner, avoiding the phenomenon of tilting of the feeding frame. The top cardboard is supported by a top wheel higher than the feeding frame, reducing the resistance of the top cardboard to the pushing of the cardboard and improving the feeding efficiency.

[0018] 2. This utility model provides an automatic feeding device for a printing machine, which is equipped with a pressing structure. The moving seat is pushed downward by the cooperation of a damping rod and a buffer spring. The downward moving seat drives the pressing wheel to press the feeding cardboard, forming a pulling force on the pushing cardboard, so as to prevent the top cardboard from continuing to squeeze the tail of the pushing cardboard when the feeding frame is recycled, thus preventing jamming.

[0030] Example 2:

[0031] The following describes the specific working method of the scheme in Embodiment 1 in further detail: The feeding structure 6 includes a reciprocating screw 601, a movable seat 602, a synchronous transmission wheel 603, and a feeding frame 606. Movable seats 602 are fixedly connected to the bottom two sides of the feeding frame 606. The reciprocating screw 601 is respectively installed inside the two movable seats 602. One end of the two reciprocating screws 601 is respectively bearing connected to the inner wall of the cavity 3, and the other end passes through the support platform 2 and is sleeved with the synchronous transmission wheel 603. The top of the feeding frame 606 is provided with an inner cavity 607. The inner cavity 607 is internally bearing... A top wheel 608 is connected, with its top end higher than the top end of the feeding frame 606. The top end of the top wheel 608 abuts against the top of the inner wall of the through hole 5. The feeding frame 606 is adapted to the through hole 5. Two movable seats 602 are slidably connected to the cavity 3. The interior of the two movable seats 602 is provided with threaded holes, which are threadedly connected to the reciprocating screw 601.

The end of one of the reciprocating screws 601 away from the storage box 4 is fixedly connected to a drive motor 604, which is electrically connected to the control panel 7.

[0032] Through the cooperation of the drive motor 604, the synchronous transmission wheel 603 and the synchronous transmission belt 605, the two reciprocating screws 601 can rotate simultaneously in the same direction, driving the moving seat 602 to reciprocate inside the cavity 3, which in turn drives the feeding frame 606 to stably push the cardboard to feed in an orderly manner, avoiding the phenomenon of the feeding frame 606 tilting. The top cardboard is supported by the top wheel 608 which is higher than the feeding frame 606, reducing the resistance of the top cardboard to the pushing cardboard and improving the feeding efficiency.

[0033] Example 3:

[0034] The following describes the scheme in Embodiment 2 in detail with reference to the specific working method: The pressing structure 12 includes a rotating shaft 1201, a pressing wheel 1202, a lifting seat 1203 and a damping rod 1204. The pressing wheel 1202 is sleeved on the outer wall of the rotating shaft 1201. The two ends of the rotating shaft 1201 are respectively connected to the lifting seats 1203 by bearings.

One end of the two damping rods 1204 is respectively fixedly connected to the inner wall of the through cavity 9, and the other end is fixedly connected to the lifting seat 1203. The outer walls of the two damping rods 1204 are respectively sleeved with buffer springs 1205.

[0035] The damping rod 1204 and the buffer spring 1205 work together to push the lifting seat 1203 downward. The downward movement of the lifting seat 1203 drives the pressing wheel 1202 to press the paperboard being fed, forming a pulling force on the pushing paperboard, so as to prevent the top paperboard from continuing to squeeze the tail of the pushing paperboard when the feeding frame 606 is recycled, thus preventing jamming.
