A U-shaped plate is slidably connected inside the groove, with the end of the U-shaped plate away from the groove fixedly connected to one of the sliders. A sliding plate is slidably connected inside the long groove, with a positioning rod fixedly installed on its surface. Multiple positioning holes are evenly distributed on one side of the base. A spring is fixedly installed between the end of the sliding plate away from the positioning rod and the inner wall of the U-shaped plate. A pull rod is fixedly installed on the end of the sliding plate away from the positioning rod, and a pull plate is fixedly installed on the end of the pull rod away from the sliding plate. This invention solves the problem that in existing creasing and cutting machines, the user may be pushed out by the flip-over plate during use, thus compromising personal safety.

[0003] In actual use, the aforementioned equipment has several drawbacks. Because the T-shaped support is equipped with multiple cutting blades and there is no outward lifting mechanism on the existing T-shaped support, the cardboard is easily stuck between the cutting blades and cannot be easily detached when cutting the cardboard. As a result, it is necessary to manually separate the cardboard from the cutting blades, which is not only time-consuming and laborious, but also unsafe to remove it manually. At the same time, when cutting the cardboard, paper scraps will remain on the cutting blades. If they are not cleaned in time, the cuts made by the cutting blades on the cardboard will not be smooth.

[0004] Therefore, a cardboard creasing and cutting machine is proposed. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: Please refer to Figure 1-4This utility model provides a technical solution: a cardboard creasing and cutting machine, including a base 1, a T-shaped support 2 on the base 1, multiple cutting blades 3 on the T-shaped support 2, an ejection mechanism and a cleaning mechanism on the T-shaped support 2, the cleaning mechanism contacting the cutting blades 3, the ejection mechanism including multiple mounting slots 4, the T-shaped support 2 having multiple mounting slots 4, two sliding blocks 41 slidably mounted on the bottom side of the mounting slots 4, and two transmission rods 42 rotatably mounted on the sliding blocks 41. A movable block 43 is rotatably mounted on the other end. A movable plate 44 is mounted on the two movable blocks 43. The movable plate 44 is slidably mounted on the mounting groove 4. Limiting rods 47 are installed on the inner walls of both sides of the mounting groove 4. Two sliding blocks 41 are slidably mounted on the limiting rods 47. A spring 45 is sleeved on the limiting rods 47. The two ends of the spring 45 are respectively mounted on the side of the two sliding blocks 41 that are close to each other. A guide groove 46 is opened on the inner wall of the bottom side of the mounting groove 4. The two sliding blocks 41 are slidably mounted on the inner wall of the guide groove 46. The cardboard is moved closer to the cutting blade 3 on the T-shaped support 2 by a flip plate. During the cutting process, the flip plate moves the cardboard and presses the moving plate 44 into the mounting groove 4, making it flush with the surface of the T-shaped support 2. At the same time, the moving plate 44 moves the movable block 43 downward, the movable block 43 drives the transmission rod 42 to rotate, and the transmission rod 42 drives the sliding block 41 on the limit rod 47 to move to both sides. The two sliding blocks 41 drive the spring 45 on the limit rod 47 to stretch. When the cardboard is processed and the flip plate separates from the T-shaped support 2, the restoring force of the spring 45 drives the sliding block 41 to move towards the middle. The sliding block 41 drives the transmission rod 42 to rotate, the transmission rod 42 drives the movable block 43 to move upward, the movable block 43 drives the moving plate 44 to move upward, and the moving plate 44 drives the cardboard to move upward. This allows the cardboard to be easily pushed out of the T-shaped support 2, avoiding the situation where the processed cardboard gets stuck in the gap between the two cutting blades 3 and cannot fall off automatically, requiring manual removal and increasing the risk of operation.

[0023] Example 2: Based on Example 1, a cleaning mechanism is provided to facilitate the cleaning of residual paper scraps on the surfaces of the T-shaped support 2 and the cutting blade 3. Specifically, it includes an extension block 5, which is installed on one side of the T-shaped support 2. Both the T-shaped support 2 and the extension block 5 are equipped with fixing plates 52. Positioning plates 51 are installed on the adjacent sides of the two fixing plates 52. A cross slider 54 is slidably mounted on the positioning plate 51. A connecting rod 55 is mounted on the cross slider 54, and a cleaning brush 56 is mounted on the connecting rod 55. The cleaning brush 56 contacts the cutting blade 3. Threaded rods 59 are rotatably mounted on the two extension blocks 5. Threaded sleeves 53 are threaded onto the threaded rods 59, and adapter blocks 510 are mounted on the threaded sleeves 53. The adapter blocks 510 are mounted on the cross sliders 52. On the slider 54, a support plate 58 is installed on the extension block 5 on one side. A motor 57 is installed on the support plate 58. The motor 57 is installed on one end of the threaded rod 59. The motor 57 drives the threaded rod 59 on the extension block 5 to rotate. The threaded rod 59 drives the threaded sleeve 53 to move. The threaded sleeve 53 drives the adapter block 510 to move. The adapter block 510 drives the cross slider 54 on the positioning plate 51 to move. The cross slider 54 drives the connecting rod 55 to move. The connecting rod 55 drives the cleaning brush 56 to reciprocate to clean the surface of the T-shaped support 2 and the cutting blade 3. This allows for quick cleaning of the paper scraps remaining on the surface of the T-shaped support 2 and the cutting blade 3 after cutting the cardboard, which facilitates the processing of the next cardboard sheet. The remaining features are the same as in Embodiment 1.

[0024] The working principle is as follows: When using the components on the base 1 to creasing and cut the cardboard, the flip plate moves the cardboard close to the cutting blade 3 on the T-shaped support 2 for cutting. During the cutting process, the flip plate moves the cardboard to press the moving plate 44 into the mounting groove 4 and make it flush with the surface of the T-shaped support 2. At the same time, the moving plate 44 moves the movable block 43 downward, the movable block 43 drives the transmission rod 42 to rotate, and the transmission rod 42 drives the sliding block 41 on the limit rod 47 to move to both sides. The two sliding blocks 41 drive the spring 45 on the limit rod 47 to stretch. When the cardboard is processed and the flip plate separates from the T-shaped support 2, the restoring force of the spring 45 drives the sliding block 41 to move towards the middle. The sliding block 41 drives the transmission rod 42 to rotate, the transmission rod 42 drives the movable block 43 to move upward, the movable block 43 drives the moving plate 44 to move upward, and the moving plate 44 moves the cardboard upward. The cardboard can be easily ejected from the T-shaped support 2, preventing it from getting stuck in the gap between the two cutting blades 3 and failing to fall off automatically, which would require manual removal and increase the risk of accidents. After the cardboard is removed, the switch of the motor 57 on the support plate 58 is immediately turned on. The motor 57 drives the threaded rod 59 on the extension block 5 to rotate. The threaded rod 59 drives the threaded sleeve 53 to move. The threaded sleeve 53 drives the adapter block 510 to move. The adapter block 510 drives the cross slider 54 on the positioning plate 51 to move. The cross slider 54 drives the connecting rod 55 to move. The connecting rod 55 drives the cleaning brush 56 to reciprocate to clean the surfaces of the T-shaped support 2 and the cutting blades 3. This allows for quick cleaning of the cardboard scraps remaining on the surfaces of the T-shaped support 2 and the cutting blades 3, facilitating the processing of the next cardboard sheet.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
