Technical Field

[0001] This invention relates to the field of paper cutter technology, and more particularly to a servo-driven computer paper cutter. Background Technology

[0002] In the fields of printing, packaging, and office automation, computerized paper cutters are core cutting equipment, and their performance directly affects production efficiency and product quality. Paper cutters are used to cut paper of various sizes. When cutting paper, one side of the entire stack of paper must first be cut flat before being cut according to specifications. Traditional paper cutters use a paper-pushing mechanism to transport the paper, and the cutter descends to cut the paper. During use, there are the following significant drawbacks: paper scraps are generated during the cutting process, requiring manual cleaning. Each time the cutter descends, the paper scraps must be cleaned manually. If not cleaned in time, it may clog moving parts and cause malfunctions. Furthermore, small granular debris is generated during the cutting process, which is difficult to clean. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a servo-driven computer paper cutter, which cleans up the debris generated during the cutting process by installing a paper scrap collection mechanism at one end of the machine, aiming to solve the problems in the background technology.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] This embodiment discloses a servo-driven computer paper cutter, such as... Figures 1-8 As shown, the device includes a machine base 100, a paper cutting mechanism 300, a paper pushing mechanism 200, and a paper scrap collection mechanism 400 mounted on the machine base 100. The paper cutting mechanism 300 is existing technology, and its specific structure will not be described in detail. The paper scrap collection mechanism 400 is mounted at one end of the machine base 100 and is used to collect and process the scraps generated during the paper cutting process to prevent the scraps from scattering on the machine base 100. The paper scrap collection mechanism 400 includes a collection box 401, a fan 403 mounted on the side of the collection box 401, and an opening and closing structure 405 mounted on the upper surface of the collection box 401. The surface of the collection box 401 is flush with the surface of the machine base 100. The opening and closing structure 405 is used to control the opening and closing of the collection box 401. When cutting paper, the opening and closing structure 405 is opened, and the collection box 401 is in the open state. The strong suction generated by the fan 403 draws the scraps generated during the cutting process into the collection box 401.

[0025] like Figures 4-6As shown, the opening and closing structure 405 includes a frame 4051, with multiple sliders 4052 slidably connected inside the frame 4051. Multiple rotating plates 4053 are rotatably connected to the sliders 4052 for sealing the frame 4051. Ropes connect adjacent sliders 4052. A drive mechanism is installed below the frame 4051 to drive the sliders 4052 to separate or assemble. The drive mechanism includes a drive motor 4057 and a threaded rod 4058 mounted on the shaft of the drive motor 4057. A sliding frame 4055 is slidably connected inside the frame 4051, and the sliding frame 4055 is fixedly connected to adjacent sliders 4052. A rotating plate 4053 is fixedly connected to the sliding frame 4055. A threaded seat 4059 is threadedly connected to the threaded rod 4058; a drive motor 4057 drives the threaded rod 4058 to rotate, thereby driving the sliding frame 4055 to slide. The sliding frame 4055 drives the adjacent sliders 4052 and rotating plates 4053 to move. The first slider 4052 drives each slider 4052 to slide in sequence through a rope, thereby controlling the distance between adjacent rotating plates 4053. When the adjacent rotating plates 4053 separate from each other, the opening and closing structure 405 opens to collect waste paper scraps. When the rotating plates 4053 contact each other, the opening and closing structure 405 closes. When the paper cutter is not in use, the opening and closing structure 405 closes to prevent dust from falling into the collection box 401.

[0026] Preferably, a gear 4054 is fixedly connected to the rotating shaft of the rotating plate 4053, and a rack 4050 that meshes with the gear 4054 is fixedly connected to the frame 4051. When the slider 4052 slides, the gear 4054 rolls on the surface of the rack 4050, causing the rotating plate 4053 to rotate. When the rotating plate 4053 rotates, it plays a flipping role, causing the paper scraps to move and fall into the collection box 401.

[0027] Preferably, the frame 4051 is provided with a receiving hole 40510 for accommodating the gear 4054. A retractable bellows 4056 is fixedly connected between the sliding frame 4055 and one end of the frame 4051. The bellows 4056 serves to seal the sliding frame 4055 and the frame 4051, and can also cooperate with the sliding of the sliding frame 4055.

[0028] Preferably, the collection box 401 has a trapezoidal structure, and a rectangular collection chamber 402 is provided at the lower end of the collection box 401. A box door 404 is connected to the collection chamber 402. A vertically arranged filter screen 406 is installed inside the collection box 401. The filter screen 406 plays the role of intercepting paper scraps and intercepting them into the collection box 401.

[0029] like Figures 7-8As shown, the paper pushing mechanism 200 is installed on the machine base 100 and is surrounded by a protective cover 500. The paper pushing mechanism 200 includes a pair of track frames 201, a slide seat 204 slidably connected to the track frames 201, a slide frame 205 fixedly connected between the two slide seats 204, and a push plate 207 for pushing the paper. The track frames 201 are fixedly installed on the machine base 100, and the push plate 207 is in contact with the paper. The track frames 201 are equipped with a slide rod 202 slidably connected to the slide seat 204, a first lead screw 203 threadedly connected to the slide seat 204, and a first motor 206 for driving the first lead screw 203 to rotate. The two first lead screws 203 are synchronously driven by a pulley and a belt, and the two first lead screws 203 rotate at the same speed. The machine base 100 is equipped with a tensioning wheel 211 for tightening the pulley. The first motor 206 drives the two first lead screws 203 to rotate simultaneously. The slide frame 205 driven by the first lead screw 203 slides, and the paper is conveyed by the push plate 207.

[0030] Preferably, a second motor 208 is installed on the slide 205, and a second lead screw 209 is fixedly connected to the shaft of the second motor 208. An adjusting frame 210 that is threadedly connected to the second lead screw 209 is slidably connected to the slide 205. A guide plate 212 that is slidably connected to the adjusting frame 210 is provided on the slide 205. The second motor 208 plays the role of fine adjustment of the position of the push plate 207. By driving the second lead screw 209 to rotate through the second motor 208, the position of the adjusting frame 210 is corrected, thereby correcting the position of the push plate 207.

[0031] The servo-driven computer paper cutter disclosed in this invention achieves efficient and precise paper cutting and debris management through integrated design. Its core working principle is as follows: When the paper cutting mechanism 300 performs cutting operations on the machine base 100, the paper debris collection mechanism 400 starts simultaneously. The surface of the collection box 401 is flush with the machine base 100. The opening and closing structure 405 automatically opens before cutting, keeping the collection box 401 open. The exhaust fan 403 generates directional suction, causing the debris generated during cutting to fall precisely onto the opening and closing structure 405 and then be directly sucked into the collection box 401, preventing debris from scattering and contaminating the working environment. After cutting is completed, the opening and closing structure 405 closes, sealing the collection box 401. 01. To prevent dust intrusion, the opening and closing structure 405 consists of a frame 4051, a sliding slider 4052, and a rotating plate 4053. A drive motor 4057 rotates a threaded rod 4058, which in turn moves the sliding frame 4055 via a threaded seat 4059, causing adjacent sliders 4052 to separate or converge along the frame 4051. The sliders 4052 are linked by ropes to ensure synchronized action: Opening process: When the sliders 4052 separate, the rotating plate 4053 flips under the meshing action of the gear 4054 and rack 4050, forming an open channel for debris to enter; Closing process: The convergence of the sliders 4052 causes the rotating plate 4053 to contact, achieving a seal. A bellows 4056 compensates for the displacement of the sliding frame 4055, maintaining the cleanliness of the inside of the frame 4051.
