Description

Technical Field

[0001] This utility model relates to the field of printing press technology, and specifically to a paper cutter mechanism for printing presses. Background Technology

[0002] In the printing press production process, paper feeding and cutting are crucial steps. The paper cutter mechanism is responsible for accurately cutting the continuously fed paper according to production needs at specific times to obtain printing paper of the specified size. This process is essential for ensuring the consistency of printed materials, improving production efficiency, and achieving automated production.

[0003] Traditional paper cutter mechanisms lack limiting functions on both sides when cutting paper, leading to errors in the cutting process. Furthermore, when the paper cutter mechanism stops working, the blade cannot be properly retracted, making it easy for operators to touch the blade and get cut. Therefore, there is an urgent need for paper cutter mechanisms for printing presses to overcome these defects. Utility Model Content

[0021] More specifically, by setting a limiting component 1 to limit the two sides of the workpiece to be cut, and by setting a cutting and storage component 2 to cut the workpiece while storing the cutter body 28, the first motor 13 is turned on according to the size of the workpiece to be cut. The first motor 13 drives the threaded rod 17 to rotate, causing the first slider 16 to drive the limiting rolling frame 15 to move inward, thereby limiting the two sides of the workpiece to be cut. After limiting, the workpiece to be cut is pushed to the designated position. The cylinder 291 is turned on, and the cylinder 291 drives the cutter body 28 to move downward, thereby cutting the workpiece to be cut. When the machine stops after cutting, the cylinder 291 drives the cutter body 28 to reset. Then the second motor 29 is turned on, and the second motor 29 drives the gear 24 to rotate, causing the protective arc seat 25 to flip to the designated position, thereby protecting the bottom of the cutter body 28. It has the advantages of good protection and limiting function.

[0022] In some embodiments, a first motor 13 is fixedly installed on the right side of the limiting seat 11, and a first sliding groove 14 is provided inside the limiting seat 11. A first slider 16 is slidably connected to both sides inside the first sliding groove 14. A limiting rolling frame 15 is fixedly installed on the top of the first slider 16. More specifically, the first slider 16 is limited by the first sliding groove 14 to prevent the first slider 16 from shaking during movement, and the limiting rolling frame 15 is limited by the first slider 16 to prevent the limiting rolling frame 15 from shaking during movement.

[0023] In some embodiments, the first slider 16 is internally connected to a threaded rod 17 via a threaded connection, and the output shaft of the first motor 13 passes through the inner cavity of the first slide groove 14 and is fixedly connected to the right side of the threaded rod 17. Positioning brackets 12 are fixedly installed on both sides of the top of the limiting seat 11. More specifically, the first motor 13 drives the threaded rod 17 and adjusts the first slider 16 via the threaded rod 17.

[0024] In some embodiments, a receiving box 21 is fixedly installed on one side of the positioning frame 12 that is relatively close to each other. Cylinders 291 are fixedly installed on both sides of the top of the inner cavity of the receiving box 21. A cutter body 28 is fixedly installed at the bottom of the cylinder 291. More specifically, the cutter body 28 is driven by the cylinder 291, and the workpiece to be cut is cut under the action of the cutter body 28.

[0025] In some embodiments, arc-shaped magnetic blocks 22 are fixedly installed on both sides of the top of the housing 21, a second motor 29 is fixedly installed on the right side of the inner cavity of the housing 21, a gear 24 is provided on the right side of the housing 21, and the output shaft of the second motor 29 passes through the right side of the housing 21 and is fixedly connected to the left side of the gear 24. More specifically, the arc-shaped magnetic blocks 22 are used to magnetically limit the protective arc-shaped seat 25, and the second motor 29 is used to drive the gear 24.

[0026] In some embodiments, a protective arc-shaped seat 25 is provided at the bottom of the housing 21, and evenly distributed teeth 23 are fixedly installed on the inner surface of the right side of the protective arc-shaped seat 25. The surface of the teeth 23 meshes with the surface of the gear 24. More specifically, the bottom of the housing 21 is sealed by providing the protective arc-shaped seat 25.

[0027] In some embodiments, the protective arc-shaped seat 25 has a second sliding groove 26 inside, and a second slider 27 is slidably connected inside the second sliding groove 26. The back of the second slider 27 is fixedly connected to the front of the receiving box 21. More specifically, the second sliding groove 26 is used to limit the second slider 27, and the second slider 27 is used to limit the protective arc-shaped seat 25 to prevent it from shaking during movement.

[0028] Working principle:

[0029] Step 1: Limit the two sides of the workpiece to be cut by setting the limiting component 1, cut the workpiece by setting the cutting and storage component 2, and store the cutter body 28 at the same time. When in use, according to the size of the workpiece to be cut, turn on the first motor 13, and drive the threaded rod 17 to rotate, so that the first slider 16 drives the limiting rolling frame 15 to move inward, thereby limiting the two sides of the workpiece to be cut. After limiting, push the workpiece to be cut to the designated position.

[0030] Step 2: Open cylinder 291, which drives the cutter body 28 to move downward to cut the workpiece. After cutting, when the machine stops, cylinder 291 drives the cutter body 28 to reset. Then, the second motor 29 is turned on, which drives the gear 24 to rotate, causing the protective arc seat 25 to flip to the designated position, thereby protecting the bottom of the cutter body 28. This has the advantages of good protection and limit function.
