[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0033] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0034] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0035] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0036] like Figures 1 to 3 As shown, this application embodiment provides a carton creasing machine, including a frame 1, a creasing assembly 2, a support platform 3, an adsorption assembly 4 and a lifting assembly 5 arranged sequentially from top to bottom on the frame 1. The top of the support platform 3 is provided with a storage groove 31 for placing cardboard, and the bottom of the support platform 3 is provided with a through hole 32 communicating with the storage groove 31.

[0037] The adsorption assembly 4 includes a suction nozzle 41, which is movably disposed in the through hole 32 and can extend into the storage slot 31, and the suction nozzle 41 is externally connected to a vacuum pump.

[0038] The creasing assembly 2 is used to creasing the cardboard, and the lifting assembly 5 is used to drive the suction nozzle 41 to move up and down.

[0039] In use, the cardboard to be crimped is placed in the storage slot 31 of the support platform 3. Then, the suction nozzle 41 uses an external vacuum pump to generate negative pressure to adsorb the bottom of the cardboard and fix it in place. Then, the cardboard is crimped by the crimping component 2. After the crimping is completed, the lifting component 5 drives the suction nozzle 41 to rise. The cardboard rises with the suction nozzle 41 until it is removed from the storage slot 31. Then, the suction function of the suction nozzle 41 is stopped, and the cardboard can be removed to complete the unloading.

[0040] This creasing machine uses an adsorption component 4 to adsorb and fix the cardboard, improving the stability of the creasing process. It also uses a lifting component 5 to push the cardboard out with the help of the suction nozzle 41. The suction nozzle 41 plays a dual role of "adsorption and fixation" and "lifting and demolding", eliminating the need for additional structures such as push rods. This solves the problem of difficulty in manually prying the cardboard, improves the convenience of board removal and unloading, reduces the cardboard breakage rate, and increases production efficiency.

[0041] like Figures 1 to 3As shown, in this embodiment, the adsorption component 4 also includes an air pipe 42 and a pipe 43. The air pipe 42 is located below the support platform 3, and the air pipe 42 is connected to a vacuum pump through the pipe 43. The suction nozzle 41 is set at the top of the air pipe 42, and the lifting component 5 is used to drive the air pipe 42 to move up and down.

[0042] When in use, turn on the external vacuum pump, and the suction nozzle 41 will generate negative pressure to adsorb the bottom of the cardboard through the pipe 43 and the air pipe 42. The pipe 43 is flexible. When the lifting component 5 pushes the air pipe 42 up and down, the pipe 43 can bend with the air pipe 42 to keep the vacuum channel unobstructed.

[0043] like Figures 1 to 3 As shown, in this embodiment, the lifting assembly 5 includes a connecting rod 51, and the frame 1 has an installation hole 11. A rotating shaft 12 is fixedly installed in the installation hole 11. The connecting rod 51 passes through the installation hole 11 and is rotatably sleeved on the rotating shaft 12. One end of the connecting rod 51 can abut against the bottom of the air pipe 42.

[0044] When in use, pressing down the other end of the connecting rod 51 causes the end of the connecting rod 51 near the air tube 42 to rise and lift the air tube 42 according to the lever principle; releasing the other end of the connecting rod 51 causes the air tube 42 to return to its original position under the action of gravity; the lifting assembly 5 adopts a mechanical transmission structure, which is simple, reliable, easy to operate, and has a low failure rate.

[0045] like Figures 1 to 3 As shown, in this embodiment, a locking component 6 is also included. The locking component 6 includes a mounting plate 61, a U-shaped plate 62, a first slide rod 63, and a second slide rod 64. The mounting plate 61 is fixedly mounted on the frame 1. The first slide rod 63 and the second slide rod 64 slide through the mounting plate 61, and one end of the first slide rod 63 and one end of the second slide rod 64 are fixedly connected to the U-shaped plate 62. The U-shaped plate 62 can be moved to engage with the connecting rod 51.

[0046] In use, press down the other end of the connecting rod 51 until the cardboard rises with the suction nozzle 41 and exits the storage slot 31. Then push the first slide rod 63 to move the U-shaped plate 62 close to the connecting rod 51 and engage with the connecting rod 51, restricting the rotation of the connecting rod 51, thereby fixing the height position of the suction nozzle 41 and mechanically locking the cardboard in the lifting state. This allows the operator to free their hands to remove the cardboard and unload it without having to continuously apply force to press down the connecting rod 51. The U-shaped plate 62 and the second slide rod 64 work together to guide and limit the U-shaped plate 62.

[0047] like Figures 1 to 3As shown, in this embodiment, the indentation assembly 2 includes a cylinder 21, a mounting frame 22, a first motor 23, a mounting base 24, a second motor 25, a screw 26, a first slider 27, and an indentation plate 28. The cylinder 21 is fixedly mounted on the frame 1, and the piston rod of the cylinder 21 is connected to the mounting frame 22. The first motor 23 is fixedly mounted on the mounting frame 22, and the output shaft of the first motor 23 is connected to the mounting base 24. A first groove 29 is provided at the bottom of the mounting base 24. The screw 26 is rotatably mounted in the first groove 29 through a bearing. The second motor 25 is fixedly mounted on the mounting base 24, and the output shaft of the second motor 25 is connected to the screw 26. The first slider 27 is limited and slidably mounted in the first groove 29, and the first slider 27 is threaded onto the screw 26. The indentation plate 28 is connected to the first slider 27.

[0048] In use, the cylinder 21 is activated, causing the mounting frame 22 to move downwards. The first motor 23 moves downwards with the mounting frame 22, the mounting base 24 moves downwards with the first motor 23, the first slider 27 moves downwards with the mounting base 24, and the creasing plate 28 moves downwards with the first slider 27 until the creasing plate 28 comes into contact with the cardboard and performs creasing. When the creasing angle needs to be adjusted, the first motor 23 is activated, causing the mounting base 24 to rotate. The first slider 27 and the creasing plate 28 rotate with the first mounting base 24, thereby adjusting the creasing angle. When the creasing position needs to be adjusted, the second motor 25 is activated, causing the screw 26 to rotate. The screw 26 causes the first slider 27 to move laterally along the first slide groove 29. The creasing plate 28 moves laterally with the first slider 27, thereby adjusting the creasing position. The cooperation between the first slider 27 and the first slide groove 29 guides and limits the first slider 27. Both the creasing angle and the horizontal position of the creasing are adjustable, which can increase the diversity of creasing patterns and adapt to the creasing needs of cardboard of different sizes and shapes.

[0049] like Figures 1 to 3 As shown, in this embodiment, the indentation plate 28 and the first slider 27 are detachably connected by bolts; the bolt connection facilitates quick disassembly and replacement of indentation plates 28 of different specifications or types, adapting to diverse production needs and further increasing the diversity of indentation patterns.

[0050] like Figures 1 to 3 As shown, in this embodiment, there are two first sliders 27 and two indentation plates 28. The threads of the two first sliders 27 are opposite, and the corresponding indentation plates 28 are connected to the corresponding first sliders 27.

[0051] When in use, the second motor 25 is turned on to drive the screw 26 to rotate. The screw 26 drives the two first sliders 27 to move laterally along the first slide groove 29 and move closer or further away from each other. The indentation plate 28 moves laterally with the first sliders 27, thereby adjusting the distance between the two indentation plates 28. The double indentation plate 28 design can improve processing efficiency.

[0052] like Figures 1 to 3 As shown, in this embodiment, a rubber ball 52 is fixedly provided at one end of the connecting rod 51. The rubber ball 52 can abut against the bottom of the air pipe 42. The rubber ball 52 at the end of the connecting rod 51 flexibly contacts the bottom of the air pipe 42, buffering the lifting impact, reducing mechanical noise, and increasing the contact area and friction through rubber deformation during lifting, preventing the connecting rod 51 from slipping with the air pipe 42 and improving the reliability of transmission.

[0053] like Figures 1 to 3 As shown, in this embodiment, a second slider 44 is fixedly installed on the air tube 42, and a second slide groove 13 is provided on the frame 1. The second slider 44 and the second slide groove 13 are connected in a limiting sliding connection. The cooperation between the second slider 44 and the second slide groove 13 provides support, limitation and guidance for the air tube 42.

[0054] like Figures 1 to 3 As shown, in this embodiment, a first handle 53 is provided at the end of the connecting rod 51 away from the air pipe 42, and a second handle 65 is provided at the end of the first slide rod 63 away from the U-shaped plate 62; the first handle 53 facilitates the operator to apply force to press down the connecting rod 51, and the second handle 65 facilitates the operator to apply force to push the first slide rod 63, thereby improving ease of use.

[0055] Working principle: When using the carton creasing machine provided in this application, the cardboard to be creasing is placed in the placement slot 31 of the support platform 3. Then, the external vacuum pump is turned on, which drives the suction nozzle 41 through the pipe 43 and air pipe 42 to generate negative pressure to adsorb the bottom of the cardboard and fix the cardboard. Then, the cylinder 21 is turned on to move the mounting frame 22 down. The first motor 23 moves down with the mounting frame 22, the mounting base 24 moves down with the first motor 23, the first slider 27 moves down with the mounting base 24, and the creasing plate 28 moves down with the first slider 27 until the creasing plate is lowered. 28 contacts the cardboard and performs creasing; when the creasing angle needs to be adjusted, the first motor 23 is turned on to drive the mounting base 24 to rotate, and the first slider 27 and the creasing plate 28 rotate with the first mounting base 24, thereby adjusting the creasing angle; when the creasing position needs to be adjusted, the second motor 25 is turned on to drive the screw 26 to rotate, and the screw 26 drives the two first sliders 27 to move laterally along the first slide groove 29 and move closer or further away from each other, and the creasing plate 28 moves laterally with the first sliders 27, thereby adjusting the distance between the two creasing plates 28 and adjusting the creasing position;

[0056] After the indentation is completed, press down the first handle 53 at the other end of the connecting rod 51. According to the lever principle, the rubber ball 52 at the end of the connecting rod 51 near the air tube 42 rises and lifts the air tube 42. The suction nozzle 41 rises with the air tube 42, and the cardboard rises with the suction nozzle 41 to the removal slot 31. Then push the second handle 65 to drive the first slide rod 63 to move. The first slide rod 63 drives the U-shaped plate 62 to approach the connecting rod 51 and engage with the connecting rod 51, restricting the rotation of the connecting rod 51, thereby fixing the height position of the suction nozzle 41. Then stop the suction function of the suction nozzle 41, and then the cardboard can be removed to complete the unloading.

[0057] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
