Description

Technical Field

[0001] This utility model relates to the field of paper cutting technology, and more specifically, to a two-hand triggering device for paper cutting. Background Technology

[0002] When paper is cut, it is often necessary to use a paper cutter to cut the paper. For example, the new paper cutter proposed in application number "CN201711144672.X" is characterized by including a machine body (1), a pressure gauge (2) installed inside the machine body (1), a worktable (3) installed on the machine body (1), a cutter (4) installed on the worktable (3), a digital display screen (5) installed on the cutter (4), a control panel (6) installed next to the digital display screen (5), and a wire box (7) installed next to the machine body (1).

[0003] However, the above-mentioned technical solutions use a single-handed control panel to trigger the cutting action, which poses a risk of accidental hand contact with the cutter, resulting in a safety accident. In addition, the control panel is in a fixed position and cannot be adjusted according to the arm span of different operators, which makes it inconvenient to operate. Therefore, we propose a two-handed triggering device for paper cutting to solve the above problems. Utility Model Content

[0004] The main purpose of this utility model is to provide a two-hand triggering device for paper cutting, which solves the problem that using a one-handed control panel to trigger the cutting action poses a safety risk of accidental hand contact with the cutter, and the control panel is fixed in position and cannot be adjusted according to the arm span of different operators, resulting in poor operation convenience.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A paper cutting two-hand triggering device includes a worktable. An isolation cover is installed at the rear end of the upper surface of the worktable. Triggering mechanisms are installed at both ends of the front surface of the worktable. A cutting blade is installed on the front side of the upper end inside the isolation cover, and a pressure block is installed on the rear side of the upper end inside the isolation cover. The cutting blade and the pressure block are parallel to each other, with their closest ends touching. Second hydraulic cylinders are installed on both sides of the upper end inside the isolation cover, with their output ends connected to the pressure block and the cutting blade, respectively. A push plate is engaged at the rear end of the inner side of the isolation cover. First hydraulic cylinders are installed at both ends of the rear side of the isolation cover, with their output ends movably penetrating the rear end of the inner side of the isolation cover and connected to the push plate. The triggering mechanism includes a sliding groove located at both ends of the front surface of the worktable. A slider is movably installed inside the sliding groove, and a button is installed on the front surface of each slider.

[0007] Preferably, the output end of the second hydraulic cylinder is equipped with a first guide rod, the lower end of the first guide rod is movably connected with a first connecting rod, the lower end of the first connecting rod is connected to the pressure block, and a second spring is installed between the upper end of the first connecting rod and the first guide rod.

[0008] Preferably, a connecting frame is installed on the upper rear side of the cutter. The shafts of the first guide rods are movably installed inside the connecting frame. Pressure plates are installed on the upper ends of the shafts of the first guide rods, and the pressure plates overlap with the connecting frame vertically. Second guide rods are installed at both ends of the upper inner surface of the isolation cover. Second connecting rods are movably installed on the lower inner ends of the second guide rods. The lower ends of the shafts of the second connecting rods are connected to the connecting frame. Third springs are sleeved on the outer sides of the shafts of the second connecting rods located inside the second guide rods.

[0009] Preferably, the inner rear side of the slide groove is provided with an auxiliary groove, the rear side of the slider is provided with an extension rod, and the rod body of the extension rod is movably located inside the auxiliary groove. Rollers are movably installed on the outer side of the rod body of the extension rod inside the auxiliary groove, and the rollers are movably installed inside the auxiliary groove.

[0010] Preferably, the slider has grooves at its upper and lower ends, and a transmission plate is movably installed inside each groove.

The slide groove 301 is located at both ends of the front surface of the workbench 1. A slider 303 is movably installed inside the slide groove 301. A button 304 is installed on the front surface of the slider 303. The button 304, the first hydraulic cylinder 7, and the second hydraulic cylinder 8 are connected to the control center inside the workbench 1 through wires.

[0025] like Figures 4 to 7As shown, in another embodiment of this utility model, the output end of the second hydraulic cylinder 8 is respectively equipped with a first guide rod 9, and the lower end of the first guide rod 9 is movably installed with a first connecting rod 10. The lower end of the first connecting rod 10 is connected to the pressure block 5. The upper end of the first connecting rod 10 and the first guide rod 9 are respectively equipped with a second spring 11. The upper rear side of the cutter 4 is equipped with a connecting frame 13. The rod body of the first guide rod 9 is movably installed inside the connecting frame 13. The upper end of the rod body of the first guide rod 9 is respectively equipped with a pressure plate 12, and the pressure plate 12 and the connecting frame 13 overlap vertically. The upper inner surface of the isolation cover 2 is respectively equipped with two second guide rods 14. The lower end of the second guide rod 14 is movably installed with a second connecting rod 15. The lower end of the rod body of the second connecting rod 15 is connected to the connecting frame 13. The outer side of the rod body of the second connecting rod 15 located inside the second guide rod 14 is respectively sleeved with a third spring 16. The rear side of the slide groove 301 is respectively provided with an auxiliary groove 302. The rear side of the slider 303 is respectively provided with an auxiliary groove 302. Extension rods 305 are respectively installed on the sides, and the rod bodies of the extension rods 305 are movably located inside the auxiliary groove 302. Rollers 306 are movably installed on the outer sides of the rod bodies of the extension rods 305 inside the auxiliary groove 302. The rollers 306 are movably installed inside the auxiliary groove 302. The upper and lower ends of the slider 303 are respectively provided with grooves 307. Transmission plates 308 are movably installed inside the grooves 307. Transmission rods 309 are movably installed through the front end of the grooves 307 on the opposite sides. Push rods 311 are movably installed through the rear end of the groove 307 on opposite sides. The ends of the push rods 311 and the transmission rod 309 that are close to each other are connected to the transmission plate 308. Several first springs 310 are installed between the transmission plate 308 and the groove 307. Several second teeth 313 are equidistantly installed at the upper and lower ends of the slide groove 301. First teeth 312 are installed at the ends of the push rods 311 that are close to the second teeth 313. The first teeth 312 and the second teeth 313 are meshed together.

[0026] Place the paper to be cut on workbench 1 and push it to the designated position inside the isolation cover 2. Then, the operator presses buttons 304 on both sides simultaneously. The signal from buttons 304 is transmitted to the control center inside workbench 1 via wires. The control center activates the second hydraulic cylinder 8, and the output end drives the first guide rod 9 downward. The first guide rod 9 pushes the pressure block 5 to contact and compact the paper through the first connecting rod 10. Then, the first guide rod 9 continues to descend, allowing the upper end of the first connecting rod 10 to slowly enter the interior of the first guide rod 9 and compress the second spring 11. This causes the first guide rod 9 to also drive the pressure plate 12 to press the connecting frame 13 downward. The connecting frame 13 then drives the cutter 4 downward to cut the paper. Simultaneously, as the connecting frame 13 moves downward, The connecting frame 13 will drive the second connecting rod 15 to move downward, so that the second connecting rod 15 will squeeze the third spring 16. Then, after the cutter 4 finishes cutting the paper, the second hydraulic cylinder 8 will drive the first guide rod 9 to move upward. Then the third spring 16 will push the second connecting rod 15, the connecting frame 13 and the cutter 4 to move upward and reset. Then, as the first guide rod 9 moves upward, the upper end of the first connecting rod 10 will connect with the lower end of the inside of the first guide rod 9 again. Then the first guide rod 9 will drive the first connecting rod 10 and the pressure block 5 to reset. Finally, the control center will start the first hydraulic cylinder 7, so that the first hydraulic cylinder 7 will push the push plate 6 and the paper to move outward, so that the paper will be removed from the inside of the isolation cover 2, making it easier for the user to pick up and adjust the paper.

[0027] When the operator needs to adjust the position of button 304 according to their arm span, the user first presses the transmission rod 309, causing the transmission rod 309 to push the transmission plate 308, which in turn compresses the first spring 310. Simultaneously, this causes the push rod 311 to separate from the first tooth 312 and the second tooth 313. The user can then control the slider 303 to adjust its position along the slide groove 301. During sliding, the extension rod 305 on the rear side of the slider 303 drives the roller 306... The auxiliary slider 303 rolls within the auxiliary groove 302 to adjust its position. After the slider 303 is adjusted, the user can release the transmission rod 309, allowing the first spring 310 to push the transmission plate 308, transmission rod 309, and push rod 311 to reset. This causes the push rod 311 to engage the first tooth 312 with the second tooth 313, thus completing the positioning of the slider 303. This ensures that when the user presses the button 304, the slider 303 provides more stable support for the button 304.

[0028] The working principle of this paper cutting two-hand trigger device:

[0029] In use, first place the paper to be cut on the workbench 1 and push it to the designated position inside the isolation cover 2. Then, the operator presses the buttons 304 on both sides simultaneously. The signal from the buttons 304 is transmitted to the control center inside the workbench 1 via a wire. The control center activates the second hydraulic cylinder 8, and the output end drives the first guide rod 9 downward, allowing the first guide rod 9 to push the pressure block 5 to contact and compact the paper through the first connecting rod 10. Then, the first guide rod 9 continues to descend, allowing the upper end of the first connecting rod 10 to slowly enter the interior of the first guide rod 9 and compress the second spring 11. This causes the first guide rod 9 to also drive the pressure plate 12 to press the connecting frame 13 downward, allowing the connecting frame 13 to drive the cutter 4 downward to cut the paper. At the same time, as the connecting frame 13... As the paper is cut, the connecting frame 13 moves downward, causing the second connecting rod 15 to press against the third spring 16. Then, after the cutter 4 has finished cutting the paper, the second hydraulic cylinder 8 moves the first guide rod 9 upward. The third spring 16 then pushes the second connecting rod 15, the connecting frame 13, and the cutter 4 upward to reset. As the first guide rod 9 moves upward, the upper end of the first connecting rod 10 connects again to the lower end of the inside of the first guide rod 9. The first guide rod 9 then drives the first connecting rod 10 and the pressure block 5 to reset. Finally, the control center activates the first hydraulic cylinder 7, which pushes the push plate 6 and the paper outward, allowing the paper to detach from the inside of the isolation cover 2, making it easier for the user to pick up and adjust the paper.

[0030] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
