The motor base 3 is fixedly installed on the base 1. A motor 4 is arranged on the top of the motor base 3, and the end of the motor 4 is connected with a motor shaft 5. The first support rod 2 close to the motor 4 is projected forward on the first support rod 2 on the motor shaft 5 A through hole 6 is opened at the position of the through hole 6, a first bearing 7 is provided in the through hole 6, and the first bearing 7 is rotatably connected to the shaft 8. The end of the motor shaft 5 is fixedly connected with one end of the shaft 8 through the first bearing 7 and the other end of the shaft 8 rotates. Connected to the first support rod 2 far away from the motor 4, the first support rod 2 far away from the motor 4 is provided with a circular groove 10 at the position where the through hole 6 is projected forwardly. The circular groove 10 is provided with a second bearing 11 and a rotating shaft 8 The other end is rotatably connected to the first support rod 2 away from the motor 4 through the second bearing 11. An electric push rod 12 is provided on one side of the first support rod 2. The electric push rod 12 is fixedly connected to the top of the base 1, and the electric push rod 12 is movable inside Connected to the piston rod 120, the piston rod 120 is fixedly installed with an infrared emitter 13 on the side close to the first support rod 2. The other side of the first support rod 2 is provided with four sets of second support rods 14, and the second support rods 14 are fixed It is mounted on the top of the base 1, a transmission belt 15 is arranged between the second support rods 14. The two ends of the transmission belt 15 are fixed by rollers 16, and both ends of the roller 16 are rotated by the third bearing 17 and the second support rod 14. The top of the transmission belt 15 is close to the end of the first support rod 2 is provided with an extrusion rod 18, the bottom of the extrusion rod 18 is fixedly connected with a connecting rod 19, and one end of the connecting rod 19 is fixedly connected to the top of the second support rod 14. There is an L plate 20 on the side of the belt 15. The L plate 20 is fixedly installed on the top of the base 1, and the bottom of the horizontal part of the L plate 20 is fixedly installed with a cylinder 21. The end of the cylinder 21 is fixedly connected with a knife holder 22, and the bottom of the knife holder 22 is clamped. A scale 24 is provided on the side of the cutting knife 23 and the vertical part of the L plate 20 close to the second support rod 14, and an infrared receiver 25 is fixedly installed in the middle of each scale line of the scale 24.

[0025] Among them, the control box 2, the motor 4, the electric push rod 12, the infrared transmitter 13, the transmission belt 15, the cylinder 21 and the infrared receiver 25 are electrically connected to the power source, and the controller 2 electrically controls the motor 4, the electric push rod 12, and infrared The transmitter 13, the transmission belt 15, the cylinder 21 and the infrared receiver 25 work; the height of the first support rod 2 is higher than the height of the second support rod 14, so that the height of the transmission roller 9 is higher than that of the transmission belt 15 Height, the height difference is used to prevent the base paper from wrinkling. The length of the conveying roller 9 is less than the distance between the two first support rods 2 to ensure that the base paper will not rub against the first support rod 2 during the conveying process, which will cause the base paper to move and affect Cutting effect; the depth of the circular groove 10 is half the width of the first support rod 2; the second support rods 14 are arranged in a rectangle, and the height of the top of the transmission belt 15 is higher than the top of the second support rod 14 and smaller than the first support rod 2 At the top, the conveyor belt 15 is made of cutting-resistant material; the cutting knife 23 and the edge of the conveyor belt 15 close to the L plate 20 are on the same vertical plane; the top of the scale 24 and the top of the conveyor belt 15 are on the edge close to the L plate 20 The same horizontal plane; the extrusion rod 18 is a hollow rod with cooling liquid inside. When the raw paper passes through the extrusion rod 18, it is squeezed and leveled and cooled.

[0026] A specific application of this embodiment is: controlling the telescopic height of the electric push rod 12 through the operation panel 260 on the controller 26, thereby controlling the height of the infrared transmitter 13, starting all the electrical components of the device, and wrapping the original paper through The conveying roller 9 is transferred to the conveying belt 15. There is a height difference between the conveying roller 9 and the conveying belt 15, which makes the wrapping paper and the horizontal plane have a certain angle to prevent the packing box paper from wrinkling. At the same time, a squeeze rod 18 is provided above the end of the conveying belt 15 , The squeeze rod 18 is equipped with coolant, and the raw paper of the packaging box is squeezed and cooled by the squeeze rod 18 to further ensure that the raw paper of the packaging box has no wrinkles. With the movement of the conveyor belt 15, the raw paper of the packaging box moves to the conveyor belt 15 At the end, the original paper of the packing box falls. When the original paper of the packing box falls to a certain height, the infrared emitter 13 is blocked, and the infrared receiver 25 cannot receive infrared rays. At this time, the control box 26 receives the signal and controls the cylinder 21 to move downwards to drive The knife holder 22 moves downwards, so that the cutting knife 23 cuts the raw paper of the packing box. After cutting, the wrapped raw paper falls on the top of the base 1, the infrared receiver 25 receives the infrared, and the control box 26 receives a signal to control the cylinder 21 to shrink upward , Repeat the above steps to cut the original packaging paper.
