Description

Technical Field

[0001] The utility model relates to the technical field of energy-saving street lamps, and specifically relates to a paper turning structure of a double-sided digital printing press. Background Art

[0002] A double-sided printing press is a device specifically used for printing on both sides of paper simultaneously. It adopts specific structures and technologies to achieve operations such as paper transmission, double-sided printing, and alignment, ensuring the accuracy of two-sided printing and the quality of finished products. Double-sided printing presses are widely used in fields such as publishing, advertising, packaging, and color page printing, and can significantly improve printing efficiency and save paper costs. Its working principle includes precise paper transmission, precision control during the printing process, and alignment of the starting points of double-sided printing, etc.

[0003] For the existing turning mechanism of a double-sided printing press, due to its complex mechanical structure and functional requirements, it is often designed to be relatively large. This not only results in a larger size of the device itself but also significantly increases its floor area in the printing workshop. Such a large-sized turning mechanism not only limits the space utilization rate of the printing workshop, reducing the compactness of the workshop layout, but also often leaves limited installation space for adding other necessary equipment inside the printing press, and even affects the smoothness and efficiency of the entire production line. Therefore, how to optimize the design of the turning mechanism, reduce its size, and improve the space utilization rate to leave enough installation space for other equipment, for this reason, we propose a paper turning structure of a double-sided digital printing press.

Detailed Embodiment

[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0034] Example 1

[0035] As Figures 1-4 shown, in this embodiment, a paper flipping structure of a double-sided printing digital printing machine includes a plate body 1. Two sliding plates 2 are fixedly connected to one side of the plate body 1. A flipping assembly 3 for flipping is arranged on the plate body 1. A clamp 38 is arranged in the flipping assembly 3 for clamping the paper for flipping. A moving assembly 4 is arranged outside the plate body 1 for moving the plate body 1 and the flipping assembly 3. By cooperating with the flipping assembly 3 that can lift and adjust the position of the clamp 38, papers of different specifications can be printed.

[0036] The flipping assembly 3 includes a lifting plate 31. The lifting plate 31 is slidably connected between the two sliding plates 2. Two first electric push rods 32 are fixedly connected to one side of the plate body 1. The driving ends of the two first electric push rods 32 are fixedly connected to the top of the lifting plate 31. A first motor 33 is fixedly connected to one end of the lifting plate 31. A driving wheel 331 is fixedly connected to the driving end of the first motor 33. A chain 332 is externally meshed and sleeved on the driving wheel 331. The other end of the lifting plate 31 is rotatably connected with a driven wheel 333. The other end of the chain 332 is meshed and sleeved outside the driven wheel 333. The driving wheel 331 and the driven wheel 333 have the same number of teeth. The axes of the driving wheel 331 and the driven wheel 333 are parallel. The pitch and the number of teeth of the driving wheel 331, the driven wheel 333 and the chain 332 are matched. The tightness of the chain 332 is moderate. When the two groups of sliders 35 slide to both ends of the limit frame 34, they stop. The limit frame 34 is fixedly connected to one side of the lifting plate 31. A limit groove 341 is opened on the limit frame 34. The slider 35 is slidably connected in the limit frame 34. The top of the slider 35 is slidably connected in the limit groove 341. The slider 35 is fixedly connected with the chain 332. A connecting block 36 is fixedly connected to the top of the slider 35. A second motor 37 is fixedly connected to one side of the connecting block 36. The driving end of the second motor 37 penetrates through the connecting block 36 and is fixedly provided with a clamp 38. The plate body 1, the sliding plates 2, the flipping assembly 3 and the moving assembly 4 are arranged in two groups, and the two groups are arranged oppositely. While the paper is unfolded and flipped, the two groups of second motors 37 respectively drive the two groups of clamps 38 to rotate correspondingly, so that when the paper is flipped in place, the two groups of clamps 38 rotate in place synchronously, avoiding creases on the paper.

[0037] In this embodiment, the number of the flipping assemblies 3 on the plate body 1 is set to two, and the two flipping assemblies 3 are arranged oppositely. The two clamps 38 are arranged oppositely. The two clamps 38 are both detachably connected to the driving ends of the second motors 37. The two groups of clamps 38 can be replaced with different specifications and can be repaired.

[0038] During specific implementation, the paper is clamped by two sets of upper and lower clamps 38. Then, the four first motors 33 in the upper and lower groups are started. The two sets of first motors 33 drive the driving wheels 331 to rotate respectively. With the assistance of the two sets of driven wheels 333, the two sets of chains 332 rotate relative to each other, driving the four sliders 35 in the two sets to slide within the limit frame 34, and then driving the upper and lower clamps 38 to move relative to each other. At the same time, the two sets of first electric push rods 32 in the upper and lower groups drive the two lifting plates 31 to lift in opposite directions under the limitation of the sliding plate 2. The distance between the two sets of four clamps 38 in the upper and lower groups is thus widened, and the paper can be unfolded and flipped. Since there is no large-scale flipping operation and there is sufficient space between the two plates 1 and at the upper and lower positions of the flipping assembly 3 to place other printing mechanisms, the floor area can be reduced.

[0039] Embodiment 2

[0040] As Figure 1 shown, in this embodiment, the moving assembly 4 includes: a moving block 41, which is fixedly connected to the corner of the plate body 1; a moving box 42, which is arranged outside the plate body 1, and the moving block 41 is slidably connected within the moving box 42; a third motor 43, which is fixedly connected to one end of the moving box 42, and the driving end of the third motor 43 extends into the moving box 42 and is fixedly connected with a screw rod 431, and the screw rod 431 is threadedly connected with the moving block 41; the number of the moving assemblies 4 on the plate body 1 is set to four, and the four moving assemblies 4 are respectively arranged at the four corners of the plate body 1, and the moving assembly 4 drives the plate body 1 to move.

[0041] During specific implementation, the two sets of third motors 43 are started. The two sets of third motors 43 drive the two sets of screw rods 431 to rotate respectively, and then drive the two sets of moving blocks 41 to move relatively in opposite directions, that is, drive the two plate bodies 1 and the components thereon to move relatively and in opposite directions. In this way, in cooperation with the flipping assembly 3 with a liftable and adjustable clamp 38 position, papers of different specifications can be printed.

[0042] Working principle: First, the paper is clamped by the upper and lower groups of clamps 38. Then, the four first motors 33 in the upper and lower groups are started. The two groups of first motors 33 drive the driving wheels 331 to rotate respectively. With the assistance of the two groups of driven wheels 333, the two groups of chains 332 rotate relatively, and then drive the four sliders 35 in the two groups to slide in the limit frame 34, and then drive the upper and lower groups of clamps 38 to move relatively. At the same time, the two groups of first electric push rods 32 in the upper and lower groups drive the two lifting plates 31 to lift in opposite directions under the limitation of the sliding plate 2. The distance between the four clamps 38 in the upper and lower groups is then widened, that is, the paper can be unfolded and flipped. While the paper is being unfolded and flipped, the two groups of second motors 37 in the upper and lower groups drive the two groups of clamps 38 to rotate correspondingly, so that when the paper is flipped in place, the two groups of clamps 38 rotate in place synchronously, avoiding creases on the paper. The two groups of third motors 43 are started, and the two groups of third motors 43 drive the two groups of screws 431 to rotate respectively, and then drive the two groups of moving blocks 41 to move relatively in opposite directions, that is, drive the two plates 1 and the components thereon to move relatively and in opposite directions. In this way, by cooperating with the flipping assembly 3 that can lift and adjust the position of the clamp 38, papers of different specifications can be printed.
