Technical Field

[0001] The present application relates to the technical field of touch-cutting machines, and in particular to a waste paper cleaning structure for touch-cutting machines. Background Art

[0002] At present, the die-cutting machine is also called a die-cutting machine, a cutting machine, and a CNC punching machine. It is mainly used for die-cutting, creasing, hot stamping, laminating, and automatic waste discharge of some corresponding non-metallic materials, self-adhesive labels, EVA, double-sided tape, electronics, mobile phone pads, etc. The die-cutting machine uses steel knives, hardware molds, and steel wires to apply a certain pressure through the stamping plate to cut the printed products or cardboard into a certain shape.

[0003] The working principle of the die-cutting machine is to use a die-cutting knife, a steel knife, a hardware mold, and a steel wire to apply a certain pressure through the stamping plate to cut the printed product or cardboard into a certain shape.

[0004] The existing Chinese patent with publication number CN209367505U discloses a waste paper separation and storage mechanism for a die-cutting machine, including a frame and a paper suction unit arranged on one side of the die-cutting cylinder of the die-cutting machine. The paper suction unit includes a paper suction cylinder and an exhaust device. The paper suction cylinder is rotatably connected to the frame. The paper suction cylinder is located below the paper receiving conveyor belt. The paper suction cylinder is arranged parallel to the die-cutting cylinder of the die-cutting machine. Paper suction grids are distributed on the surface of the paper suction cylinder. A waste paper collection box is also arranged on the frame below the paper suction cylinder.

[0005] When using the above-mentioned waste paper separation and storage mechanism for the die-cutting machine, the exhaust device is turned on to absorb the scraps scattered by the die-cutting drum of the die-cutting machine onto the paper suction grille on the paper suction cylinder. At the same time, the paper suction cylinder can also absorb the scraps transmitted by the paper receiving conveyor belt onto the paper suction grille on the paper suction cylinder. The scraps rotate with the paper suction cylinder to the bottom and then fall into the waste paper collection box, thereby completing the centralized absorption, separation and storage of the scraps generated by the die-cutting machine.

[0006] With respect to the above-mentioned related technologies, the inventor believes that after the cardboard is cut by the die-cutting machine, some scraps will still stick to the cardboard, so the staff needs to manually remove the scraps from the cardboard, which increases the workload of the staff.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments.

[0034] The following is combined with Figure 1-5 This application is described in further detail.

[0035] The embodiment of the present application discloses a waste paper cleaning structure for a touch-cutting machine.

[0036] Reference Figure 1-Figure 2A waste paper cleaning structure for a touch-cutting machine includes a cabin 1, a frame 2 is arranged in the cabin 1, and an inlet 11 and an outlet 12 are formed on the cabin 1, and a first conveyor belt 3 is arranged on the frame 2, and both ends of the first conveyor belt 3 are respectively connected with the extended inlet 11 and the outlet 12. When in use, the cardboard enters from the inlet 11 of the cabin 1 under the action of the first conveyor belt 3, and the cardboard is moved out from the outlet 12 after passing through the cabin 1. A pressing component 5 and a removing component 6 are arranged in the cabin 1, and the pressing component 5 moves the first conveyor belt 3 to the side close to the frame 2, and the removing component 6 removes the waste paper on the cardboard. A second conveyor belt 4 is arranged on the lower side of the frame 2 at the first conveyor belt 3, and the waste paper on the cardboard falls on the second conveyor belt 4.

[0037] Reference Figure 3 A support plate 21 is provided on the frame 2, and the support body is in a rectangular plate shape as a whole, and the length direction of the support plate 21 is horizontally arranged. A suspension rod 22 is provided on the support plate 21, and a plurality of suspension rods 22 are evenly spaced on the support plate 21, and one end of the suspension rod 22 is connected to the support plate 21, and the other end is connected to the top of the cabin 1.

[0038] The first conveyor belt 3 is rotatably connected to the side of the support plate 21 in the thickness direction away from the suspension rod 22, and the frame 2 is located at the lower side of the first conveyor belt 3. A first drive motor 23 is provided on the support plate 21, and the first drive motor 23 is installed on the support plate 21, and the output shaft of the first drive motor 23 is connected to the first conveyor belt 3. When in use, the first drive motor 23 drives the first conveyor belt 3 to rotate. As the first conveyor belt 3 rotates, the cardboard moves between the first conveyor belt 3 and the frame 2.

[0039] Reference Figure 4-Figure 5 In the process of the first conveyor belt 3 moving the cardboard, due to the different thickness of the cardboard, if the thickness of the cardboard is thin, the first conveyor belt 3 cannot drive the cardboard to move. Therefore, after improvement by the designer, the pressing assembly 5 includes a pressing plate 51, which is in the shape of a rectangular plate as a whole, and is arranged parallel to the support plate 21 with a spacing therebetween.

[0040] When in use, the pressing plate 51 passes through the middle of the first conveyor belt 3 in the horizontal direction, and a guide rod 52 is provided on the pressing plate 51. Four guide rods 52 are provided at intervals on the pressing plate 51. One end of each of the four guide rods 52 is connected to the pressing plate 51, and the other end passes through the upper support plate 21 in the vertical direction. When in use, the pressing plate 51 presses the first conveyor belt 3 toward the side close to the frame 2.

[0041] In addition, in order to improve the convenience of adjusting the first conveyor belt 3 by the pressing plate 51, a screw rod 53 is provided on the pressing plate 51, and two screw rods 53 are arranged at intervals on the pressing plate 51, one end of each of the two screw rods 53 is connected to the pressing plate 51, and the other ends of each of the two screw rods 53 pass through the support plate 21. Further, nuts 54 are provided on each of the two screw rods 53, and two nuts 54 are arranged at intervals corresponding to the screw rods 53, and the two nuts 54 are located on both sides of the thickness direction of the support plate 21, and the nuts 54 are threadedly connected to the screw rods 53, and one side of the two nuts 54 on the screw rods 53 respectively contacts the two sides of the support plate 21.

[0042] When in use, the two nuts 54 are rotated to improve the convenience of adjusting the position of the screw rod 53 on the support plate 21. When the pressing plate 51 needs to be adjusted, the two nuts 54 on the screw rod 53 are rotated to move the pressing plate 51 closer to or away from the side of the frame 2.

[0043] Furthermore, anti-scratch arc surfaces 511 are formed on both sides of the pressing plate 51 in the length direction, and the anti-scratch arc surfaces 511 face the side close to the frame 2. When the pressing plate 51 moves the first conveyor belt 3 to the side close to the frame 2, the anti-scratch arc surfaces 511 contact the first conveyor belt 3, thereby preventing the corners of the pressing plate 51 from scratching the first conveyor belt 3, thereby improving the service life of the first conveyor belt 3.

[0044] In addition, in order to improve the stability of the cardboard moving between the first conveyor belt 3 and the frame 2, the first conveyor belt 3 is provided with anti-skid protrusions 31, and a plurality of anti-skid protrusions 31 are evenly spaced on the first conveyor belt 3. The plurality of anti-skid protrusions 31 are all made of rubber. When in use, the anti-skid protrusions 31 on the first rubber pad are pressed against the cardboard, thereby improving the friction between the cardboard and the first conveyor belt 3.

[0045] When in use, the side of the frame 2 close to the first conveyor belt 3 is made of a smooth iron plate. Since the surface of the iron plate is relatively smooth, the friction between the cardboard and the first conveyor belt 3 is greater than the friction between the cardboard and the frame 2. Therefore, the first conveyor belt 3 can slide on the frame 2 against the cardboard.

[0046] When cutting the cardboard, in order to reduce waste of the cardboard, the die-cutting machine will only cut the two sides of the cardboard, so the first conveyor belt 3 conveys the middle part of the cardboard.

[0047] The material removal assembly 6 includes a material removal cylinder 61, and two support rods 62 are respectively arranged on both sides of the support plate 21 in the width direction. One end of the support rod 62 is connected to the support plate 21, and the other end extends horizontally away from one side of the support rod 62.

[0048] The material removal cylinder 61 corresponds to the support rod 62, and a guide groove 63 is provided on the support rod 62, and the length direction of the guide groove 63 is parallel to the length direction of the support rod 62. The material removal cylinder 61 is installed on the corresponding support rod 62, and one end of the piston rod of the material removal cylinder 61 passes through the guide groove 63 on the corresponding support rod 62. When the material removal cylinder 61 moves to a specified position along the guide groove 63, the material removal cylinder 61 is installed on the support rod 62 by fixing bolts.

[0049] Furthermore, a stripping plate 64 is provided on both sides of the conveying direction of the first conveyor belt 3. The stripping plate 64 is in the shape of a rectangular plate as a whole, and the stripping plate 64 is arranged horizontally in the length direction. When in use, the stripping plate 64 is connected to the piston rods of the two stripping cylinders 61 on both sides of the length direction, so that the stripping cylinders 61 can drive the stripping plate 64 to move up and down.

[0050] In addition, a rubber sheet 65 is provided on the side of the material removal plate 64 that is away from the material removal cylinder 61 in the thickness direction. The rubber sheet 65 is screwed onto the material removal plate by screws, and a pressing groove 651 is provided on the rubber sheet 65. During the opening process of the pressing groove 651, the cross section of the pressing groove 651 matches the cutting part of the edge of the cardboard, so that when the material removal cylinder 61 drives the material removal plate 64 to press the waste paper of the cardboard, the rubber sheet 65 can match the edge of the cardboard, so that the waste paper can fall off the cardboard better. Therefore, each time when processing different types of cardboard, the staff selects rubber sheets 65 of different types to install on the material removal plate 64.

[0051] When removing different types of cardboard, due to the different sizes of cardboard, the frame 2 needs to support different ranges of cardboard. If the cardboard is large and the support range of the frame 2 is small, the cardboard will be easily bent. Therefore, after improvement, the designer sets a slide bar 24 on the frame 2. The slide bar 24 is located on both sides of the frame 2 near the first conveyor belt 3 in the horizontal direction. One end of the two slide bars 24 is connected to the frame 2, and the other end extends to the side away from the frame 2 in the horizontal direction.

[0052] The frame 2 is provided with a slide plate 25, which is slidably mounted on the slide bar 24. When in use, the slide plate 25 slides on the slide bar 24. When in use, the slide plate 25 slides on the slide bar 24, so that the slide plate 25 can support cardboards of different sizes, greatly improving the waste paper removal efficiency of the cardboards.

[0053] After the waste paper falls from the cardboard, it falls on the second conveyor belt 4. The frame 2 is provided with a second drive motor 26, which is installed on the frame 2. When in use, the second drive motor 26 drives the second conveyor belt 4 to rotate on the frame 2. When the waste paper falls on the second conveyor belt 4, the second drive motor 26 drives the second conveyor belt 4 to rotate on the frame 2, so that the waste paper can be sent out from the cabin 1.

[0054] The implementation principle of a waste paper cleaning structure for a die-cutting machine in the embodiment of the present application is as follows: the nut 54 on the screw rod 53 is rotated, and the first conveyor belt 3 is pressed against the screw rod 53 and the pressing plate 51 to adjust the spacing between the first conveyor belt 3 and the frame 2, and then the slide plate 25 is moved along the slide rod 24 to the side close to the frame 2, so that the slide plate 25 supports both sides of the cardboard, and then the material removal cylinder 61 is adjusted to move the material removal cylinder 61 to the upper side of the slide plate 25. When in use, the first conveyor belt 3 takes out the cardboard in the die-cutting machine, and as the first driving motor 23 drives the first conveyor belt 3 to rotate, the cardboard moves between the first conveyor belt 3 and the frame 2. The cardboard moves to the upper side of the slide plate 25 driven by the first conveyor belt 3. At this time, the material removal cylinder 61 drives the material removal plate 64 to move to the side close to the frame 2, and the rubber plate 65 on the material removal plate 64 removes the waste paper on the cardboard, and the waste paper falls on the second conveyor belt 4. At this time, the second driving motor 26 drives the second conveyor belt 4 to rotate, and the second conveyor belt 4 sends the waste paper out of the cabin 1.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
