Description

Technical Field

[0001] This utility model belongs to the field of corrugated cardboard cutting technology, and specifically relates to a corrugated cardboard cutting machine. Background Technology

[0002] Corrugated cardboard cutting machines play a vital role in the packaging industry. They can precisely cut large pieces of corrugated cardboard to specific sizes and shapes, thereby meeting the needs of different product packaging. Through efficient and precise cutting, they provide the foundation for producing high-quality corrugated cardboard packaging.

[0003] However, current corrugated cardboard cutting machines have some significant drawbacks. For situations requiring cutting at two points on the cardboard, since there is usually only one cutting blade, two cutting operations are necessary. This greatly increases the complexity and time cost of operation. Taking mass production as an example, if each cardboard requires two cuts, the accumulated repetitive operation time will be considerable, seriously affecting production efficiency. Secondly, this two-cutting method is prone to errors in the accuracy of the cutting position. After the first cut, it is difficult to ensure that the two cuts are perfectly aligned when making the second cut, which may result in deviations, thus affecting the quality and performance of the cardboard. In summary, existing corrugated cardboard cutting machines, because they can only cut at one point at a time, have many disadvantages such as cumbersome operation and time consumption when facing tasks requiring multiple cuts. Therefore, we have developed a corrugated cardboard cutting machine to solve the above problems. Utility Model Content

A central rotating rod with external threads is installed in the threaded hole. A servo motor is installed in the middle of the side frame away from the lifting crossbar. A sliding port is installed on the front and rear sides of the side frame respectively. A side slider is provided between the two sliding ports. A cutting blade is installed below the movable adjustment rod.

[0008] In a preferred embodiment, the rear ends of the two side sliders are respectively connected to the front and rear ends of the movable adjustment rod, and the output end of the servo motor is connected to the central rotating rod.

[0020] 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.

[0021] Please see Figures 1 to 3 This utility model provides a technical solution: a corrugated cardboard cutting machine, including: a cutting table 1, an electric slide table 2 and a supporting base frame 3. An electric slide table 2 is installed on the front and rear sides above the cutting table 1, and a movable frame 4 is connected in the middle above the two electric slide tables 2. Two cutting cylinders 5 are installed on the movable frame 4.

[0022] Below the mobile frame 4 is a lifting crossbar 6. On the left and right sides of the lifting crossbar 6, there is a set of adjustment components 7. Both sets of adjustment components 7 include a side frame 71, a servo motor 72, and a moving adjustment rod 73.

[0023] A movable adjustment rod 73 is provided in the middle of the side frame 71. A threaded hole with internal threads is opened in the middle of the movable adjustment rod 73. A central rotating rod 74 with external threads is installed in the threaded hole. A servo motor 72 is installed in the middle of the side of the side frame 71 away from the lifting crossbar 6. A sliding port 75 is installed on the front and rear sides of the side frame. A side slider 76 is provided in the middle of the two sliding ports 75. A cutting blade 77 is installed below the movable adjustment rod 73.

[0024] The rear ends of the two side sliders 76 are connected to the front and rear ends of the movable adjustment rod 73, respectively, and the output end of the servo motor 72 is connected to the central rotating rod 74.

[0025] The central rotating rod 74 is connected to the threaded hole by a threaded rotation. A bearing is installed in the middle of the side connecting frame 71 near the lifting crossbar 6. The rear end of the central rotating rod 74 is connected to the inner side of the bearing.

Then, by activating the two servo motors 72 on the left and right, the servo motors 72 can drive the central rotating rod 74 to rotate. When the central rotating rod 74 rotates, it can drive the moving adjusting rod 73 to move within the side connecting frame 71 through the threaded hole. The moving adjusting rod 73 drives the side slider 76 to slide within the sliding opening 75. At the same time, the moving adjusting rod 73 can drive the cutting blade 77 to move. The forward and reverse rotation of the servo motors 72... The movable adjusting rod 73 moves left and right within the side connecting frame 71, thereby facilitating the flexible adjustment of the cutting position of the cutting blade 77. After adjustment, the cutting cylinder 5 can be activated. The cutting cylinder 5 can drive the lifting crossbar 6 to descend through the piston rod, thereby driving the two side connecting frames 71 to descend, and then driving the two cutting blades 77 to descend to cut the corrugated cardboard. Through the above steps, the final effect is that the distance between the two cutting blades 77 can be adjusted according to different cutting needs, and two cuts can be completed at one time, reducing operation steps and time, and making it easier to meet diverse cutting needs.
