Description

Technical Field

[0001] This utility model relates to the field of printing paper cutting technology, specifically a quantitative cutting device for printing paper. Background Technology

[0002] Digital printing is a new printing method that prints computer files directly onto paper, unlike the cumbersome processes of traditional printing. Its features include: printing from a single sheet, no plate making required, immediate availability, instant error correction, variable printing options, and on-demand printing.

[0003] According to the announcement number CN217225811U, a quantitative cutting device for printed paper includes a machine body, on which a cutting platform is provided and a cutting opening is provided.

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] During operation, in the printing production process, when multiple stacks of printing paper are neatly stacked on the placement table, manual placement errors often result in the paper edges not being perfectly aligned. If this stacking deviation is not corrected in time and the paper is cut directly, it will cause excessive trimming of the paper edges, leading not only to waste of raw materials and reduced paper utilization, but also to defective products due to substandard cutting, affecting the production efficiency and quality stability of printed materials, and increasing production costs and resource consumption. Utility Model Content

[0006] The purpose of this invention is to provide a quantitative cutting device for printing paper to solve the problems mentioned in the background art.

A cutter is fixedly connected to the bottom of the top plate, and a relay is fixedly connected to the top of the top plate. The two electric push rods and the relay are electrically connected.

[0016] Compared with the prior art, the present invention provides a quantitative cutting device for printing paper, which has the following advantages:

[0017] 1. This quantitative cutting device for printed paper, through the adjustment mechanism, threaded rod and threaded hole are connected by threads. The threaded rod can move. When the threaded rod moves, it drives the connecting plate to slide on the surface of the long rod. At the same time, the threaded rod can also drive the push plate. The push plate drives the bottom plate to move, which can push the printed paper placed on the placement plate to the left so that the right side of the paper is aligned. The rotating component drives the rotating rod, which drives the placement plate to rotate. This makes it easy to rotate the paper placed on the placement plate and adjust the misaligned cutting part to the bottom of the cutter. Repeating the operation of the pushing component can cut off the misaligned parts of multiple sheets of paper.

[0018] 2. This quantitative paper cutting device uses a cutting mechanism and a relay to control two electric push rods to start or stop simultaneously. The electric push rods can move the top plate, which in turn can drive the cutter to cut the left side of the paper, making it easier to cut off the uneven parts on the left side of the printed paper.

[0027] This utility model provides the following technical solution:

[0028] Example 1

[0029] Combination Figures 1 to 3 A quantitative cutting device for printing paper includes a workbench 1 and a placement plate 2. An adjustment mechanism 4 is provided on the workbench 1 and the placement plate 2, and a cutting mechanism 3 is provided on the top left side of the workbench 1.

[0030] The adjusting mechanism 4 includes a pushing component 41 and a rotating component 42, with the rotating component 42 located on the right side of the pushing component 41;

[0031] The feeding assembly 41 includes a limiting plate 418, which is fixedly connected to the top right side of the workbench 1. The limiting plate 418 has a threaded hole 413 inside. A long rod 417 is fixedly connected to the right side of the limiting plate 418. A connecting plate 416 is slidably connected to the surface of the long rod 417. A motor 415 is fixedly connected to the right side of the connecting plate 416. A threaded rod 414 is fixedly connected to the left side of the motor 415. A push plate 419 is rotatably connected to the left side of the threaded rod 414. A base plate 412 is fixedly connected to the bottom of the push plate 419. A rectangular groove 411 is opened around the top of the placement plate 2.

[0032] There are two long rods 417, which are set on the front and rear sides of the threaded hole 413. The surface of the threaded rod 414 and the inside of the threaded hole 413 are threadedly connected. There are four rectangular slots 411, which are set with openings on the top and the outside. The bottom plate 412 is set inside the rectangular slots 411.

[0033] The rotating assembly 42 includes an annular slide 426, which is opened on the top of the workbench 1. A rotating rod 427 is fixedly connected to the center of the bottom of the placement plate 2. A handle 422 is fixedly connected to the bottom of the rotating rod 427. Annular sliding plates 421 are fixedly connected to the bottom of the placement plate 2. Slots 423 are opened on the top of the workbench 1. Fixed plates 425 are fixedly connected to the surface of the placement plate 2. Telescopic plates 424 are fixedly connected to the bottom of the fixed plates 425.

[0034] Handle 422 is located at the bottom of workbench 1, placement plate 2 is located at the top of workbench 1, there are four slots 423, the top of the four slots 423 is set as an opening, the four slots 423 are located on the outside of the annular slide 426, and the surface of telescopic plate 424 is inserted into the inside of slot 423.

[0035] Furthermore, as the threaded rod 414 moves, it causes the connecting plate 416 to slide on the surface of the long rod 417. At the same time, the threaded rod 414 can also drive the push plate 419, which in turn drives the base plate 412 to move. This allows the printed paper placed on the placement plate 2 to be pushed to the left, aligning the right side of the paper. The rotating component 42 is then turned to drive the rotating rod 427, which in turn drives the placement plate 2 to rotate. This allows the paper placed on the placement plate 2 to be rotated, thus adjusting the misaligned cutting portion to the bottom of the cutter 33. By repeating the operation of the pushing component 41, multiple misaligned portions of the paper can be cut off.

[0036] Example 2

[0037] See Figure 1-4 Furthermore, based on Embodiment 1, the cutting mechanism 3 further includes a limiting seat 31, which is fixedly connected to the front and rear sides of the workbench 1. An electric push rod 32 is fixedly connected to the top of the limiting seat 31. A top plate 35 is fixedly connected to the top of the two electric push rods 32. A cutter 33 is fixedly connected to the bottom of the top plate 35. A relay 34 is fixedly connected to the top of the top plate 35. The two electric push rods 32 and the relay 34 are electrically connected.

[0038] Furthermore, the relay 34 telecom controls the simultaneous start or stop of the two electric push rods 32. Under the operation of the electric push rods 32, the top plate 35 can be moved, and the top plate 35 can drive the cutter 33 to cut the left side of the paper, so as to cut off the uneven part on the left side of the printed paper.

[0039] In actual operation, when this device is used to cut the printing paper, the paper is first placed on the placement plate 2. The base plate 412 is set in the rectangular groove 411, and the paper is placed on the top of the base plate 412. When the motor 415 is started, it drives the threaded rod 414 to rotate. Since the threaded rod 414 and the threaded hole 413 are connected by threads, the threaded rod 414 can move. When the threaded rod 414 moves, it drives the connecting plate 416 to slide on the surface of the long rod 417. At the same time, the threaded rod 414 can also drive the push plate 419. The push plate 419 drives the base plate 412 to move, which can push the printing paper placed on the placement plate 2 to the left so that the right side of the paper is aligned.

[0040] The relay 34 controls the simultaneous start or stop of the two electric push rods 32. The operation of the electric push rods 32 can drive the top plate 35 to move. The top plate 35 can drive the cutter 33 to cut the left side of the paper, making it easier to cut off the uneven part on the left side of the printed paper.

[0041] The rotating component 42 is turned to drive the rotating rod 427, which in turn drives the placement plate 2 to rotate. This allows the paper placed on the placement plate 2 to rotate easily. At the same time, the annular slide plate 421 slides in the annular groove 426, and the telescopic plate 424 is stretched and inserted into the slot 423, which can limit and fix the position of the placement plate 2. This makes it easy to adjust the misaligned cutting part to the bottom of the cutter 33. Repeating the operation of the pusher component 41 can cut off multiple misaligned paper parts.
