Description

Technical Field

[0001] This utility model relates to the field of printing presses, and in particular to a paper printing flattening mechanism for printing presses. Background Technology

[0002] A paper flattening mechanism for printing presses is an auxiliary device used in conjunction with printing equipment to flatten the surface of paper after the printing process. Its core function is to use a specific structure to act on the printed paper to eliminate problems such as wrinkles and warping caused by ink adhesion, temperature changes or the material properties of the paper during the printing process, ensuring that the paper remains flat so that it can be cut, bound, stacked and other processes can be carried out. This improves the overall quality and ease of use of the printed products and is widely used in various paper printing production fields such as book printing, packaging printing, and commercial invoice printing.

[0003] In the use of existing printing presses, during continuous flattening operations, when the pressure roller comes into contact with the surface of the printed paper, the ink that is not completely dried on the paper is easily adhered to the outer wall of the pressure roller. Existing mechanisms lack a convenient pressure roller replacement mechanism. If not cleaned in time, the residual ink will transfer to the surface of the next sheet of paper to be flattened. Therefore, in response to the above-mentioned problems, a paper printing flattening mechanism for printing presses has been proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1-3This utility model provides an embodiment of a paper flattening mechanism for a printing press, comprising a placement platform 1 and a support frame 2. The placement platform 1 is used to support the paper to be flattened, and the support frame 2 provides a supporting foundation for the entire mechanism. A telescopic rod B8 is fixedly connected to the inner wall of the support frame 2, and the telescopic rod B8 is used to drive a connecting frame 3 to slide up and down along the support frame 2 to adjust the height. A connecting frame 3 is slidably connected to the outer wall of the support frame 2, and the connecting frame 3 is used to install and support components such as a servo motor 4 and a conversion mechanism 6. The servo motor 4 is fixedly connected to the outer wall of the connecting frame 3, and the servo motor 4 is a connecting plate 614. The rotation provides power. A conversion mechanism 6 is provided on the outer wall of the connecting frame 3. The conversion mechanism 6 is used to realize the position conversion and replacement of the pressure roller 914. The conversion mechanism 6 includes a card holder 611, which cooperates with a chuck 612 through a rectangular slot to achieve stable support for the connecting plate 614. The outer wall of the card holder 611 is fixedly connected to one side of the outer wall of the connecting frame 3. The chuck 612 is inserted into the inner wall of the card holder 611. The chuck 612 cooperates with the slot of the card holder 611 to fix the position of the connecting plate 614. A connecting rod 613 is fixedly connected to the outer wall of the chuck 612. The connecting rod 613 is used for connecting... The connecting rod 613 connects to the chuck 612 and the connecting plate 614 and transmits motion. The connecting plate 614 is fixedly connected to the outer wall of the right end of the connecting rod 613. The connecting plate 614 is used to install the bracket 615 and drive it to rotate. The bracket 615 is hinged to the outer wall of the connecting plate 614. The bracket 615 is used to install the telescopic rod A616 and can be kept stable under the action of the spring 618. The telescopic rod A616 is fixedly connected to the outer wall of the bracket 615. The telescopic rod A616 is used to adjust the position of the pressure roller 914 to adapt to different papers. The outer wall of the telescopic rod A616 is provided with a fixing mechanism 9 for stable fixing. The pressure roller 914 prevents the paper from falling off. The fixing mechanism 9 includes the pressure roller 914, which is used to roll and flatten the paper. The pressure roller 914 is inserted into the inner wall of the telescopic rod A616. The inner wall of the card holder 611 has a card slot. The card slot is rectangular and can be precisely matched with the chuck 612 to achieve stable engagement. The outer wall of the bracket 615 is fixedly connected to the connecting plate 617. The connecting plate 617 is used to connect the spring 618 and transmit elastic force. The outer walls of the connecting plate 617 are fixedly connected to the spring 618. The spring 618 keeps the bracket 615 stable through elastic force.

[0029] Reference Figures 2-4There are two sets of telescopic rods A616 and pressure rollers 914. The two sets of telescopic rods A616 and pressure rollers 914 are symmetrically arranged on the outer wall of the connecting plate 614. The symmetrical arrangement of the two sets can improve the uniformity and efficiency of paper flattening. The upper extension end of the telescopic rod B8 is fixedly connected to the bottom of the outer wall of the connecting frame 3. The telescopic rod B8 directly drives the connecting frame 3 to rise and fall by telescopic extension. The output end of the servo motor 4 is fixedly connected to a cylinder 5. The cylinder 5 is used to drive the connecting plate 614 and related components to move back and forth to realize the separation and engagement of the chuck 612 and the chuck seat 611. The extension end of the cylinder 5 is fixedly connected to the outer wall of the connecting plate 614. The fixing mechanism 9 also includes a side plate 911. The side plate 911 is used to install the insertion rod 912 and the lever 913 and provide support. The outer wall of the side plate 911 is fixedly connected to the outer wall of the telescopic rod A616. A rod 912 is inserted into the inner wall of the side plate 911. The rod 912 is used to pass through the pressure roller 914 to achieve initial fixation. The outer wall of the extended end of the rod 912 extends outward through the inner wall of the pressure roller 914. A slot is opened on the outer wall of the rod 912. The slot is used to cooperate with the lever 913 to limit the position of the rod 912. A lever 913 is hinged to the outer wall of the side plate 911. The lever 913 is locked in the slot of the rod 912 to prevent the rod 912 from falling off. The outer wall of the lever 913 is locked in the inner wall of the rod 912. There are four sets of fixing mechanisms 9. The four sets of fixing mechanisms 9 are symmetrically connected to the outer walls of the four sets of telescopic rods A616. The four sets of symmetrical arrangement can ensure that both sets of pressure rollers 914 are firmly fixed. The outer wall of the rod 912 is hexagonal. The hexagonal shape can prevent the rod 912 from rotating during use and affecting the fixing effect.

[0030] Working principle: During operation, the telescopic rod B8 fixed to the inner wall of the support frame 2 first controls the sliding of the connecting frame 3 along the outer wall of the support frame 2 to adjust the height of the connecting frame 3 to adapt to paper of different thicknesses or printing requirements. When the paper needs to be flattened, the servo motor 4 is started. The output end of the servo motor 4 drives the cylinder 5 to operate. The extension end of the cylinder 5 can drive the connecting plate 614 and the connecting rod 613 and chuck 612 connected to it to move. When the chuck 612 is located in the rectangular slot of the chuck seat 611, it can achieve stable support for the connecting plate 614. At this time, the bracket 615 hinged to the outer wall of the connecting plate 614 remains stable under the elastic action of the spring 618 between the connecting plates 617. The telescopic rod A616 fixed on the bracket 615 can be extended and retracted as needed to adjust the position of the pressure roller 914 so that the two sets of symmetrically arranged pressure rollers 914 can accurately press down onto the paper surface on the placement table 1. The rolling of the pressure rollers 914 flattens the printed paper to ensure that the paper is flat.

[0031] When it is necessary to replace the pressure roller 914 with a different specification, the cylinder 5 retracts to move the connecting plate 614, connecting rod 613, and chuck 612, causing the chuck 612 to disengage from the slot of the chuck seat 611. Subsequently, the servo motor 4 drives the connecting plate 614 to rotate, realizing the position change or replacement operation of the pressure roller 914. During replacement, first move the lever 913 hinged to the outer wall of the side plate 911 in the fixing mechanism 9 to disengage the lever 913 from the slot of the outer wall of the insert rod 912. Then, pull out the hexagonal insert rod 912 so that it no longer penetrates the inner wall of the pressure roller 914, and the pressure roller 914 can be moved from the telescopic rod A6. After removing the inner wall of the telescopic rod A616 and replacing it with a new pressure roller 914, insert the new pressure roller 914 into the inner wall of the telescopic rod A616. Then, insert the rod 912 through the inner wall of the pressure roller 914 and into the inner wall of the side plate 911. Finally, rotate the lever 913 to lock it into the slot of the rod 912, thus limiting the rod 912 to prevent it from falling off. The four symmetrically arranged fixing mechanisms 9 can ensure that both sets of pressure rollers 914 are firmly fixed. After the pressure roller 914 is replaced, the chuck 612 is re-locked into the slot of the chuck seat 611 through the cooperation of the cylinder 5 and the servo motor 4 to continue the paper flattening operation.
