Description

Technical Field

[0001] This utility model relates to the technical field of corrugated cardboard processing equipment, specifically to an intelligent CNC corrugated cardboard crimping and forming machine. Background Technology

[0002] CNC corrugated cardboard creasing and forming machines are based on digital control technology, using pre-set programs to precisely control the movement and pressure of the creasing rollers. Operators input the specifications of the corrugated cardboard (such as thickness, flute type, creasing position, creasing depth, etc.) into the CNC system. The system converts these instructions into electrical signals, driving the motor to precisely control the rotational speed, pressure, and lateral movement distance of the creasing rollers. During processing, the creasing rollers precisely creasing the corrugated cardboard according to the set program, ensuring that the position, depth, and strength of each creasing line meet the requirements.

[0003] When CNC corrugated cardboard creasing and forming machines crimp corrugated paper, different types of corrugated paper may have stiffer or less flexible fibers due to factors such as material, thickness, and flute shape. As a result, the crimped creases may be rough and uneven, or the internal fibers may not be able to stretch and bend effectively, making them prone to breakage at the crease due to stress concentration, thus affecting the crimping quality of the corrugated paper.

[0004] Therefore, there is an urgent need for an intelligent CNC corrugated cardboard crimping and forming machine to solve the above problems. Utility Model Content

Detailed Implementation

[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

[0023] Please see Figures 1-6 The figure shows an intelligent CNC corrugated cardboard creasing and forming machine, including a frame 101 and an upper pressure roller 102 and a lower pressure roller 103 symmetrically arranged on the frame 101. The side walls of the upper pressure roller 102 and the lower pressure roller 103 are respectively provided with a plurality of creasing wheels 104 and creasing grooves 105. The frame 101 is provided with two sets of conveying rollers 106 on both sides of the upper pressure roller 102 and the lower pressure roller 103. The frame 101 is provided with a control panel 107 for digital control of the corrugated cardboard creasing process, and also includes a softening component provided on the frame 101 for softening the fibers of the corrugated cardboard before creasing.

[0024] The softening component includes two symmetrically arranged rotating rollers 201 rotatably connected to the frame 101. The two rotating rollers 201 are close to the side of the corrugated cardboard feeding direction. The two rotating rollers 201 are connected to a plurality of mounting rings 202 through a connecting component. Each mounting ring 202 is a hollow ring and has a plurality of electric heating rings 203 inside.

[0025] It should be noted that the softening component is used to soften the fibers of the corrugated cardboard before crimping, reducing its brittleness. This makes the softened cardboard more susceptible to plastic deformation during crimping, resulting in clearer and more regular folds. This reduces the risk of roughness, unevenness, or breakage during crimping, thus improving the quality of the crimping process. Simultaneously, the detection component automatically adjusts the heating device's power based on the deviation between the set and measured temperatures, achieving precise temperature control and preventing adverse effects from excessively high or low temperatures. This enhances the intelligence of the corrugated cardboard heating and softening process.

[0026] Please see Figure 5 and Figure 6 The connecting assembly shown in the figure includes multiple connecting grooves 301 formed on the side wall of the rotating roller 201. Each connecting groove 301 is slidably connected to a connecting plate 302. The ends of each connecting plate 302 that are far apart from each other are connected to the inner wall of the mounting ring 202. Each connecting plate 302 is provided with a limiting component for limiting the connection with the connecting groove 301.

[0027] It should be noted here that the connection components are designed to install the mounting ring 202 and facilitate positional adjustment according to the crease position of the corrugated cardboard.

[0028] Please see Figure 5 and Figure 6 The limiting component shown in the figure includes a limiting cavity 401 opened in the connecting plate 302. A through hole 402 is opened on the side of the limiting cavity 401 near the inner wall of the connecting groove 301. A limiting plate 403 is slidably connected to the through hole 402. The limiting cavity 401 is provided with a telescopic component for extending and retracting the limiting plate 403. The connecting plate 302 is provided with a driving component for driving the limiting plate 403.

[0029] It should be noted here that the limiting component is used to limit the connection between the mounting ring 202 and the rotating roller 201.

[0030] Please see Figure 5 and Figure 6The telescopic assembly shown in the figure includes telescopic rods 502 fixedly connected between two opposing inner walls of the limiting cavity 401. The two telescopic rods 502 are located on both sides of the limiting plate 403. The side walls of the two telescopic rods 502 are slidably connected to telescopic plates 501. One end of the two telescopic plates 501 is connected to the limiting plate 403. Springs 503 are sleeved on the side walls of the two telescopic rods 502. The two ends of the two springs 503 are respectively connected to the telescopic plates 501 and the inner wall of the limiting cavity 401.

[0031] It should be noted here that the telescopic component is designed to guide and reset the movement of the limit plate 403.

[0032] Please see Figure 5 and Figure 6 The driving assembly shown in the figure includes a threaded rod 601 threadedly connected to one side of the connecting plate 302. A driving rod 602 is fixedly connected to one end of the threaded rod 601 away from the limiting plate 403. A driving hole with a regular hexagonal shape is opened at the end of the driving rod 602 away from the threaded rod 601. An inclined surface 603 is opened on the side of the limiting plate 403 close to the threaded rod 601.

[0033] It should be noted here that the setting of the drive component makes it easy to push the limit plate 403 closer to the inner wall of the connecting groove 301.

[0034] Working principle: When creasing corrugated cardboard, the upper pressure roller 102 and lower pressure roller 103 are replaced according to the creasing position of the corrugated cardboard. At the same time, under the connecting action of the connecting components, an appropriate number of mounting rings 202 are fitted onto the two rotating rollers 201, and the position of each mounting ring 202 corresponds to the creasing position of the corrugated cardboard.

[0035] After each mounting ring 202 is fitted onto the rotating roller 201, the drive rod 602 is rotated using an L-shaped hex wrench, which in turn drives the threaded rod 601 to rotate. Under the threaded engagement of the threaded rod 601 and the connecting plate 302, the threaded rod 601 moves closer and closer to the limiting plate 403. When the threaded rod 601 abuts against the inclined surface 603 on the side wall of the limiting plate 403, under the interaction force and the guiding action of the telescopic component, the limiting plate 403 will be pushed closer and closer to the inner wall of the connecting groove 301. As the threaded rod 601 rotates continuously, it will push the limiting plate 403 to abut against the inner wall of the connecting groove 301, thereby achieving the connection and limiting of the mounting ring 202 and the rotating roller 201. The remaining mounting rings 202 are installed and connected in the same way.

[0036] After the mounting rings 202 are connected and limited, the corrugated cardboard can be conveyed from the feed port. When the corrugated cardboard is conveyed to each mounting ring 202, the fibers of the corrugated cardboard will soften under the heating action of the electric heating rings 203 inside each mounting ring 202, reducing its brittleness. As a result, the softened corrugated cardboard is more likely to undergo plastic deformation during the creasing process, and the resulting fold lines are clearer and more regular. This reduces the risk of the corrugated cardboard becoming rough, uneven or breaking during the creasing process, thereby improving the creasing and forming quality of the corrugated cardboard.

[0037] Furthermore, during the process of heating and softening corrugated cardboard, the temperature of the heated area of ​​the corrugated cardboard can be detected by the detection component, accurately measuring the real-time temperature of the corrugated cardboard. Then, based on the deviation between the set temperature and the actual measured temperature, the power of the heating device is automatically adjusted to achieve precise control of the heating temperature, avoiding adverse effects on the cardboard caused by excessively high or low temperatures, thereby improving the intelligence of heating and softening corrugated cardboard.

[0038] After being heated and softened, the corrugated cardboard is conveyed to the upper pressure roller 102 and lower pressure roller 103 by the conveying roller 106. Then, using digital control technology, the movement and pressure of the upper pressure roller 102 and lower pressure roller 103 are precisely controlled by a pre-set program. The operator inputs the specifications of the corrugated cardboard (such as thickness, flute type, crease position, crease depth, etc.) into the CNC system. The system converts these instructions into electrical signals, which drive the motor to precisely control the rotation speed, pressure, and lateral movement distance of the upper pressure roller 102 and lower pressure roller 103. During the processing, the upper pressure roller 102 and lower pressure roller 103 perform precise crease pressing on the corrugated cardboard according to the set program, ensuring that the position, depth, and strength of each crease meet the requirements.

[0039] Example 2

[0040] Please see Figure 2 This embodiment further illustrates Example 1. The frame 101 in the figure is provided with a detection component for detecting the temperature of the corrugated cardboard after heating. The detection component includes a U-shaped plate 701 fixedly connected to the frame 101. The U-shaped plate 701 is provided with a plurality of temperature detection sensors 702, and each temperature detection sensor 702 is arranged opposite to the heating part of the corrugated cardboard.

[0041] It should be noted here that the detection component is used to detect the temperature of the corrugated cardboard heating area, accurately measuring the real-time temperature of the corrugated cardboard. Then, combined with a high-precision PID (proportional-integral-derivative) controller, the power of the heating device is automatically adjusted according to the deviation between the set temperature and the actual measured temperature, so as to achieve precise control of the heating temperature and avoid adverse effects on the cardboard caused by excessively high or low temperatures, thereby improving the intelligence of corrugated cardboard heating and softening.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
