It should be understood that the implementation of this utility model is not limited to the following embodiments, and any modifications and / or alterations made to this utility model will fall within the protection scope of this utility model.

[0032] like Figure 1-6As shown, this utility model discloses a technical solution: a printing material cutting device, including a frame 1. Adjustable feet 2 are installed at the four corners of the bottom of the frame 1. Adjusting the adjustable feet 2 allows the device to remain horizontal. The adjustable feet 2 are commercially available, and their specific structure will not be described here. Two sets of guide baffles 3 are horizontally arranged on the upper surface of the frame 1, forming a feeding channel 4 between them for placing printed materials. During the cutting process, the printed materials are manually fed to one side. A discharge port 5 is opened at the right end of the guide baffles 3 on the frame 1. A bolt is bolted below the discharge port 5. A receiving hopper 33 is fixedly installed to collect the cut printed materials; an inverted U-shaped first support frame 6 is fixedly installed above the discharge port 5 by bolts, and an inverted U-shaped second support frame 7 is fixedly installed on the top of the first support frame 6 by bolts. A telescopic component 8 is fixedly installed at the center of the top of the second support frame 7 by bolts. The telescopic component 8 is made of a cylinder, hydraulic cylinder or push rod motor, which can be purchased from the market. Its specific structure and principle are existing technologies and will not be described in detail here. A tool holder mounting plate 9 is slidably connected inside the first support frame 6, and the telescopic component 8 can drive the tool holder mounting plate 9 to move up and down.

[0033] Specifically, a cutting blade 11 is mounted on the bottom of the blade holder mounting plate 9 via a blade holder plate 10. A blade pad plate 12, which works in conjunction with the cutting blade 11, is fixed to the left side of the feed port 5 via bolts. The cutting blade 11 and the blade pad plate 12 work together to complete the cutting action. A clamping component for clamping printed materials is also mounted on the lower surface of the blade holder mounting plate 9. This component is used to clamp the printed materials during cutting.

[0034] Specifically, the guide baffle 3 is provided with a plurality of longitudinal first elongated holes 13 along its length direction, and the upper surface of the frame 1 is provided with first fixing holes 14 that cooperate with the first elongated holes 13. The distance between the two sets of guide baffles 3 can be adjusted by fasteners such as bolts to accommodate printed materials of different widths.

[0035] Specifically, the first support frame 6 has two vertically arranged first guide rods 15 inside. The bottom of the first guide rod 15 is fixedly connected to the upper surface of the frame 1 by bolts. The tool holder mounting plate 9 is slidably connected to the first guide rod 15 to ensure the stability of the tool holder mounting plate 9 when moving up and down. The top center of the tool holder mounting plate 9 is fixedly connected to a vertical connecting rod 16 by bolts. The top of the connecting rod 16 passes upward through the top of the first support frame 6. The telescopic end of the telescopic component 8 passes downward through the top of the second support frame 7 and is fixedly connected to the top of the connecting rod 16. The upper end of the connecting rod 16 is welded or bolted to a first limiting block 17. The outer wall of the connecting rod 16 is fitted with a first elastic element 18. The first elastic element 18 is located between the upper surface of the first support frame 6 and the lower surface of the first limiting block 17, and plays a buffering role. In this embodiment, the first elastic element 18 is a spring.

[0036] Specifically, a limiting post 19 is also fixedly installed on the frame 1 below the tool holder mounting plate 9 by bolts. In this embodiment, there are two limiting posts 19, one in the front and one in the back. When the telescopic component 8 moves the tool holder mounting plate 9 downward, it will contact the top of the limiting post 19, thereby limiting the downward movement of the tool holder mounting plate 9.

[0037] Specifically, the clamping assembly includes a second guide rod 20, a clamping plate 21, and a second elastic element 22. There are four second guide rods 20, which are respectively fixed to the four corners of the upper surface of the clamping plate 21 by bolts. The top of the second guide rod 20 passes through the tool holder mounting plate 9 and is welded or bolted to a second limiting block 23. The second elastic element 22 is sleeved on the outer wall of the second guide rod 20 and abuts against the lower surface of the tool holder mounting plate 9 and the upper surface of the clamping plate 21. The second elastic element 22 is a spring.

[0038] Specifically, the blade holder plate 10 is provided with two front and rear second fixing holes 24, and the cutting blade 11 is provided with two front and rear second elongated holes 25 that cooperate with the second fixing holes 24. The second elongated holes 25 are vertically arranged and can adjust the vertical position of the cutting blade 11. The middle part of the clamping plate 21 is provided with a through groove 26 for the bottom of the cutting blade 11 and the blade holder plate 10 to pass through.

[0039] Specifically, the frame 1 is provided with an alignment assembly on the right side of the feed port 5. The alignment assembly includes a first mounting frame 27, a second mounting frame 28, and an alignment stop bar 29. The first mounting frame 27 and the second mounting frame 28 are respectively installed on the front and rear sides of the feed port 5 by bolts. One end of the alignment stop bar 29 is rotatably connected to the upper surface of the first mounting frame 27 through a rotating shaft. A vertical alignment plate 30 is integrally provided on the left side of the second mounting frame 28. When the alignment stop bar 29 rotates toward the second mounting frame 28, it can contact the left side of the alignment plate 30. By rotating the alignment stop bar 29 to contact the alignment plate 30, the alignment of the printed matter can be achieved.

[0040] Specifically, both the first mounting bracket 27 and the second mounting bracket 28 are provided with two sets of third elongated holes 31 at the front and rear. The third elongated holes 31 are arranged horizontally, and the upper surface of the frame 1 is provided with two sets of third fixing holes 32 that cooperate with the third elongated holes 31, so as to adjust the left and right positions of the alignment components.

[0041] The present invention provides a printing material cutting device. In use, the printed material is placed into the feeding channel 4, and the position of the guide baffle 3 is adjusted according to the width of the printed material. After adjustment, the printed material is manually pushed towards the alignment component. The alignment baffle 29 is rotated in advance to make it contact the alignment plate 30, so as to facilitate the alignment of the printed material. The telescopic component 8 is activated, which drives the knife holder mounting plate 9 to move down. The pressing component first contacts the printed material and presses it down. It continues to move down, and the cutting knife 11 and the knife pad plate 12 cooperate to complete the cutting. After the cutting is completed, the telescopic component 8 drives the knife holder mounting plate 9 to move up, and the cut printed material falls from the feeding port 5 into the receiving hopper 33.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
