[0022] The following will clearly and completely describe the technical solutions of the present invention in conjunction with specific embodiments. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.
[0023] Example: A cutting device for corrugated cardboard, such as Figure 1-3 As shown, it includes a cardboard wire saw machine 1 and a cardboard moving mechanism 2 for cooperating with the cardboard wire saw machine 1 to cut cardboard. The cardboard moving mechanism 2 includes a machine tool 21 fixed to one side of the cardboard wire saw machine 1, a pair of C-shaped plates 22 movably arranged on the machine tool 21, a driving component 23 for driving the two C-shaped plates 22 to move relative to the machine tool 21, two pairs of belt rollers 24 respectively arranged on the bottom edges of the two C-shaped plates 22 for vertical rotation, two conveying belts 25 respectively sleeved on the two pairs of belt rollers 24, and a pair of worm gear reduction motors 26 respectively driving one belt roller 24 on the two C-shaped plates 22 to rotate. The two C-shaped plates 22 are symmetrically located on both sides of the wire saw blade of the cardboard wire saw machine 1, and the openings of the two C-shaped plates 22 are opposite to each other. A worm gear reduction motor 26 is fixedly mounted on each of the C-shaped plates 22. The upper end of a belt roller 24 on the C-shaped plate 22 rotates through the top edge of the C-shaped plate 22 and is fixedly connected to the output end of the worm gear reduction motor 26. The width of the bottom edge of the C-shaped plate 22 is greater than the spacing between the two sides of the conveyor belt 25, and one side of the conveyor belt 25 abuts against the vertical edge of the C-shaped plate 22. The drive assembly 23 includes a pair of parallel and horizontally rotatable screw rods 231 mounted on the machine tool 21, a pair of worm gear reduction motors 232 fixedly mounted on the machine tool 21 and fixedly connected to one end of the two screw rods 231, and a pair of nuts 233 fixedly connected to the bottoms of the two C-shaped plates 22 and threadedly connected to the two screw rods 231. The belt roller 24 and the conveyor belt 25 are meshing synchronous toothed rollers and synchronous toothed belts, respectively, which can further improve the accuracy of the conveyor belt 25 in clamping and pushing the cardboard, thereby effectively ensuring the accuracy of the cardboard cutting process.
[0024] like Figure 3 、 Figure 4 As shown, two parallel guide grooves 211 are provided on the surface of the machine tool 21, and a slider 221 is fixedly provided at the bottom of the C-shaped plate 22 to slide in the two guide grooves 211. By adopting the above-mentioned guide grooves 211 and sliders 221, the sliding stability of the C-shaped plate 22 on the machine tool 21 can be further improved.
[0025] like Figure 3 、 Figure 4 As shown, the bottom of each of the two guide grooves 211 is formed with a groove 1 212, and the width of the groove 1 212 is greater than the width of the guide groove 211. The two nuts 233 slide in the two grooves 1 212, and the two screw rods 231 rotate in the two grooves 1 212. The worm gear reduction motor 232 is fixedly mounted on one end of the machine tool 21. One end of the screw rod 231 rotates from the end of the groove 1 212 to pass through the side wall of the machine tool 21 and is fixedly connected to the output end of the worm gear reduction motor 232. By adopting the above-mentioned groove 1 212, not only can a safe transmission space be provided for the screw rod 231 and the nut 233, but it can also cooperate with the slider 221 to stably drive the C-shaped plate 22 to move relative to the machine tool 21.
[0026] like Figure 3 、 Figure 4 As shown, a second groove 213 is formed on each side wall of the guide groove 211, and the width of the second groove 213 is smaller than the height of the guide groove 211. A pair of rollers 222 are rotatably provided on each side of the slider 221, and the two pairs of rollers 222 roll in the two second grooves 213. By using the second groove 213 and rollers 222, the friction between the slider 221 and the guide groove 211 can be effectively reduced, thereby further ensuring the stability of the C-shaped plate 22 sliding relative to the machine tool 21.
[0027] like Figure 3 As shown, a support plate 223 is vertically fixed to the bottom edge of the C-shaped plate 22. The support plate 223 is located between the two belt rollers 24 and in the middle of the conveyor belt 25. One side of the support plate 223 is in parallel contact with the inner side of the conveyor belt 25, away from the vertical side of the C-shape. The use of the support plate 223 provides support for the side of the conveyor belt 25 that grips the cardboard, thereby further improving the stability of the conveyor belt 25 gripping the cardboard.
[0028] like Figure 2As shown, an accordion-folding shield 1 27 is connected between the bottom edges of the two C-shaped plates 22. Limit plates 214 are fixedly mounted on either side of the two C-shaped plates 22 on the machine tool 21. The two limit plates 214 are connected to accordion-folding shields 28 between the vertical edges of the two C-shaped plates 22. The two guide grooves 211 are covered by the accordion-folding shield 1 27, the accordion-folding shield 2 28, and the bottom edges of the two C-shaped plates 22. The use of the accordion-folding shield 1 27 and the accordion-folding shield 2 28 effectively prevents cardboard cutting waste from falling into the guide grooves 211 and the groove 1 212, thereby fully ensuring the stable sliding of the slider 221 and the safe transmission of the screw rod 231 and the nut 233.
[0029] like Figure 1 As shown, a protective housing 11 is fixedly mounted on one side of the cardboard wire saw 1 connected to the machine tool 21. This housing 11 encloses the top, rear, and left and right ends of the machine tool 21. This housing 11 not only effectively isolates noise but also prevents waste from scattering, which could negatively impact the environmental quality of the cardboard cutting process. Double-opening inspection doors 111 are located at each end of the housing 11, facilitating easy access to various components of the machine tool 21 and ensuring safe operation of the device.
[0030] The working principle of this embodiment is as follows:
[0031] When it is necessary to cut and process the corrugated cardboard, first, the two worm gear reduction motors 232 drive the two screw rods 231 to rotate synchronously in the opposite direction, so that the nuts 233 threadedly connected to the two screw rods 231 respectively move along the screw rods 231, and then the two C-shaped plates 22 connected to the two nuts 233 through the slider 221 will move closer to each other under the drive of the nuts 233 until the two sides of the cardboard can be placed on the bottom edges of the C-shaped plates 22; then, the cardboard is placed on the bottom edges of the two C-shaped plates 22, while ensuring that one end of the cardboard and the side of the C-shaped plate 22 facing the cardboard wire saw machine 1 are aligned; then, the two worm gear reduction motors 232 continue to drive the two screw rods 231 to rotate synchronously in the opposite direction, The conveying belts 25 on the two C-shaped plates 22 clamp the two sides of the cardboard; finally, the worm gear reduction motor 232 drives the two screws 231 to rotate synchronously in the same direction to control the two C-shaped plates 22 to drive the cardboard to move horizontally, while the worm gear reduction motor 1 26 on the top edges of the two C-shaped plates 22 synchronously drives the two belt rollers 24 to rotate in the opposite direction to control the friction of the two conveying belts 25 to drive the clamped cardboard to move horizontally and longitudinally. In this way, not only the same cutting processing effect as the traditional CNC sawing machine is achieved, but the two conveying belts 25 can also fully clamp the two sides of the cardboard while pushing the cardboard to move, thereby effectively improving the safety and stability of the cardboard clamping and movement.
