Structural principle: In this V-groove hemming machine, the rubber roller 67 is used to support the cardboard material, and the cardboard material is driven to move horizontally under the drive of the first motor 33. The cooperation of the first correction unit 7 and the second correction unit 9 can ensure that The cardboard material moves horizontally and steadily along the U-shaped fixing frame 3 to ensure the processing quality. The cooperation of the first calibration unit 7 and the second calibration unit 9 can ensure that the cardboard material moves along the U-shaped fixing frame 3 to form a straight line Movement to ensure the processing quality; the pressing unit 13 is used to flatten and press the cardboard material, which not only can ensure that the surface of the processed cardboard material is relatively flat, but also prevents the V-groove opening unit 12 from opening the upper surface of the cardboard material During the V-groove, the cardboard material is shifted to ensure the quality of the opened V-groove. The glue supply unit 6 is used to pour glue into the opened V-groove, and the hemming unit 8 is used to open the cardboard material along one side. The V-groove is bent, and under the action of the glue, the cardboard material with folding edges can be processed for the next process; the dust hood 51 is used to collect the paper dust generated during the work of the V-groove opening unit 12 For dust, the suction fan 53 sucks out the paper dust collected by the dust collecting cover 51, and connects the dust suction device 5 to the factory dust treatment system through the connecting flange 49, which can effectively prevent the paper dust from spreading around the folding machine. Can eliminate the hazards of paper dust to the operator;

Working principle: The V-groove hemming machine, when in use, adjusts the working parameters through the touch screen 57 and aligns the edge of the cardboard material with the first roller 64 and the first infrared sensor that are close to the position of the first motor 33 39 The cardboard material is detected, and the detected material signal is uploaded to the PLC controller 59. The PLC controller 59 controls the first motor 33 to drive the rubber roller 67 to rotate far, and at the same time controls the second motor 41 to drive the grinding wheel 42 to rotate and start the suction fan 53 The paper material is then transported between the pressing roller 18 and the rubber roller 67, and then enters below the grinding wheel 42, the grinding wheel 42 rubs against the upper surface of the cardboard material, and then the paper surface contacting the grinding wheel 42 is ground away, thereby Grinding out the same V-shaped groove as the edge of the grinding wheel 42, the dust generated by the grinding enters the inside of the dust collecting hood 51, connects the dust suction device 5 with the dust treatment system in the factory through the connecting flange 49, and the suction fan 53 will The paper dust collected by 51 is sucked out for purification treatment. When the cardboard material moves below the second infrared sensor 11, the second infrared sensor 11 uploads the sensing signal to the PLC controller 59, which controls the body of the hot melt adhesive machine 10 work, apply glue to the inside of the V groove. When the second infrared sensor 11 can not detect the cardboard material, the PLC controller 59 controls the hot melt adhesive machine body 10 to stop the glue supply, thereby saving raw materials, when the cardboard material moves to the hem When the unit 8 is in contact with the fourth roller 31 on the side of the cardboard material, the V-groove is previously opened, so that the side of the cardboard material is easily tilted, and the first correction behind the hemming unit 8 during the progress of the cardboard material Unit 7 is in contact, so that one side of the cardboard material is folded up, and the adhesion of glue is added to form a cardboard material with a folded edge.
