Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1-4 The utility model provides a technical solution: an adjustable paper tube chamfering machine, comprising a workbench 1 and a fixed frame 2, the workbench 1 is equipped with the fixed frame 2, the workbench 1 is equipped with a feeding mechanism 5 and a limiting mechanism 6, the fixed frame 2 is equipped with a first cylinder 3, the output end of the first cylinder 3 is fixed with a movable platform 4, and the movable platform 4 is equipped with a chamfering mechanism 7.

[0020] The feeding mechanism 5 includes a guide frame 501, a second cylinder 502, a feeding frame 503, a slot 504 and an inclined surface 505. The guide frame 501 is fixed on the workbench 1, and the guide frame 501 is installed obliquely, and a slot is provided on the guide frame 501; the second cylinder 502 is fixed on the workbench 1, and the feeding frame 503 is fixed on the output end of the second cylinder 502; the feeding frame 503 is provided with a slot 504, and the front end of the feeding frame 503 is provided with an inclined surface 505; the limiting mechanism 6 includes a third cylinder 601 , a movable splint 602 and a fixed splint 603, the third cylinder 601 is fixed on the workbench 1, and the movable splint 602 is fixed to the output end of the third cylinder 601; the upper end surface of the movable splint 602 is lower than the lower end surface of the card slot 504, and the width of the movable splint 602 is smaller than the width of the loading rack 503; a fixed splint 603 is provided directly above the movable splint 602, and the fixed splint 603 is fixed on the fixed rack 2, and the center of the fixed splint 603 is on the same horizontal line as the center of the chamfering mold 704;

[0021] When using this adjustable paper tube chamfering machine, if Figures 1-4As shown, first, the cut paper roll is placed on the guide rack 501. Due to the inclined structure of the guide rack 501, the paper roll can be automatically rolled to the front opening of the guide rack 501. At this time, the second cylinder 502 is controlled to contract and drive the loading rack 503 to move backward. When the slot 504 cooperates with the front opening of the guide rack 501, the paper roll falls into the slot 504. Then the second cylinder 502 is controlled to extend and drive the slot 504 and the paper roll forward to be just above the movable splint 602, thereby realizing automatic loading. At this time, the loading rack 503 blocks the paper roll above and below the guide rack 501 to facilitate loading from the lower side. After the paper roll is loaded, the third cylinder 601 is extended to drive the movable splint 602 to move. When the movable splint 602 is aligned with the slot When the paper roll contacts the upper paper roll 504, the paper roll can be pushed upward until the paper roll contacts the fixed splint 603. At this time, the fixed splint 603 and the movable splint 602 can realize the fixing effect of the paper roll, so that the paper roll chamfering can be carried out subsequently. After the movable splint 602 pushes the paper roll upward, the second cylinder 502 contracts to load the next paper roll. At this time, the inclined surface 505 is located on both sides of the third cylinder 601. When the paper roll processing is completed, the third cylinder 601 contracts to drive the fixed splint 603 to move downward and reset. During the process, when the paper roll contacts the inclined surface 505, the fixed splint 603 continues to move downward to separate the paper roll from the fixed splint 603. The paper roll automatically rolls down with the action of the inclined surface 505, thereby realizing automatic unloading of the paper roll.

[0022] The chamfering mechanism 7 includes a motor 701, a fixed plate 702, a mounting plate 703, a chamfering mold 704, a slide bar 705 and a spring 706. The motor 701 is fixed on the movable table 4. The fixed plate 702 is fixed on the output shaft of the motor 701. The side of the fixed plate 702 is provided with a mounting plate 703. The chamfering mold 704 is fixed on the mounting plate 703. The slide bar 705 is fixed at an equal angle on the mounting plate 703, and the slide bar 705 and the fixed plate 702 are slidably connected. A spring 706 is also fixed between the mounting plate 703 and the fixed plate 702; the slider 401 is symmetrically fixed to the front and rear of the lower end surface of the movable table 4, and the slider 401 is slidably connected to the guide rail 402, and the guide rail 402 is fixed to the workbench 1;

[0023] After the paper tube is fixed by the fixed clamping plate 603 and the movable clamping plate 602, Figures 1-4As shown, at this time, the first cylinder 3 is controlled to start to drive the movable platform 4 and the chamfering mechanism 7 to move, and the sliding guide effect between the slider 401 and the guide rail 402 can ensure the stability of the movement of the movable platform 4 and the chamfering mechanism 7. When the chamfering mold 704 contacts the paper tube, the first cylinder 3 continues to extend, so that the chamfering mold 704 and the mounting plate 703 are forced to move toward the fixed plate 702. The sliding guide effect between the slide bar 705 and the fixed plate 702 can ensure the stability of the movement of the chamfering mold 704 and the mounting plate 703. At this time, the spring 706 is forced to contract, and the spring 706 is pressed The elastic action can provide a force for the chamfering mold 704, so that the chamfering mold 704 generates pressure on the paper tube to ensure the normal chamfering of the paper tube. Through the action of the spring 706, the rigid contact between the chamfering mold 704 and the paper tube can be transformed into a flexible structure to avoid damage to the paper tube. The pressure between the chamfering mold 704 and the paper tube can also be adjusted by adjusting the contraction length of the spring 706 to better meet the chamfering requirements of the paper tube (the elastic force f of the spring 706 = kx, x is the contraction length of the spring 706). This is the working principle of the adjustable paper tube chamfering machine.
