[0015] See also Figure 1-2As shown, a corrugated cardboard conveyor belt edge trimming device comprises a frame 1, on which a conveyor belt 2 for conveying corrugated cardboard is arranged, the top of the frame 1 is provided with cylinder plates 3 on both sides of the conveyor belt 2, telescopic cylinders 4 are installed on the two cylinder plates 3, and push plates 5 are arranged at the telescopic ends of the telescopic cylinders 4, the top of the frame 1 is provided with T-shaped frames 6 on one side of the two cylinder plates 3, and one side of the two T-shaped frames 6 is hinged with a movable plate 7, an edge trimming box 8 is arranged at one end of the conveyor belt 2 in the frame 1, and an edge trimming device 9 is arranged above the edge trimming box 8 on the top of the frame 1 to stably fix the corrugated cardboard to ensure that it will not move or shake during the edge trimming process, thereby improving the accuracy and stability of the edge trimming, and can also adapt to corrugated cardboards of different sizes or shapes, thereby improving the application range and flexibility of the device.

[0016] The trimming device 9 includes two micro cylinders 91, which are connected to the top of the frame 1. A slide rail 92 is arranged on the top of the two micro cylinders 91. A slider 93 is slidably connected to the slide rail 92. The outer surface of the slider 93 is connected to a trimming tool holder 94. A trimming blade 98 is arranged at the bottom of the trimming tool holder 94. Both ends of the slide rail 92 are provided with a travel baffle 95. A stepper motor 99 is arranged at one end of the slide rail 92. The rotating end of the stepper motor 99 passes through one of the travel baffles 95 and is connected to a screw rod 96. The screw rod 96 is threadedly connected to the trimming tool holder 94. One end of the screw rod 96 is rotatably connected to the other travel baffle 95. The micro cylinder 91 starts The cylinder 91 drives the slide rail 92 to move upward, and then the corrugated cardboard is transferred to the trimming box 8 to adapt to corrugated cardboards of different heights. Then the micro cylinder 91 is controlled to drive the slide rail 92 to move downward. When the trimming blade 98 touches the surface of the corrugated cardboard, the stepper motor 99 is started to drive the screw rod 96 to rotate. Because the screw rod 96 is threadedly connected with the trimming knife seat 94, the trimming knife seat 94 can move on the screw rod 96, thereby controlling the trimming blade 98 to move back and forth. At the same time, the micro cylinder 91 is controlled to increase the downward pressure of the trimming blade 98, so as to better cut the corrugated cardboard, ensure the accuracy and consistency of the trimming operation, and improve the product quality.

[0017] The bottom of the edge trimming tool holder 94 is connected to an edge trimming tool clamp block 97, and the edge trimming blade 98 is installed on the edge trimming tool clamp block 97 by bolts, which is convenient for replacement and maintenance;

[0018] The edge cutting blade 98 is made of a high-hardness and wear-resistant material, has a long service life, and reduces maintenance costs.

[0019] Working principle: Place the corrugated cardboard on the conveyor belt 2, push the push plate 5 through the telescopic cylinder 4, so as to stabilize the position of the corrugated cardboard during the trimming process, and the movable plate 7 is connected to the T-frame 6 through a hinge so that its position can be freely adjusted when needed to adapt to corrugated cardboard of different sizes or shapes, start the micro cylinder 91 to drive the slide rail 92 to move upward, and then the corrugated cardboard is conveyed to the trimming box 8 to adapt to corrugated cardboard of different heights, and then control the micro cylinder 91 to drive the slide rail 92 to move downward, when the trimming blade 98 touches the surface of the corrugated cardboard, start the stepper motor 99 to drive the screw rod 96 to rotate, because the screw rod 96 is threadedly connected to the trimming tool holder 94, the trimming tool holder 94 can move on the screw rod 96, thereby controlling the trimming blade 98 to move back and forth, and at the same time controlling the micro cylinder 91 to increase the downward pressure of the trimming blade 98, so as to better cut the corrugated cardboard, when the trimming blade 98 needs to be replaced, only the bolt needs to be loosened for replacement, which is very convenient.
