[0019] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention, and cannot be construed as a limitation to the present invention.

[0020] Embodiment of the present invention: As Figures 1 - 5 shown, a glue supply amount adjusting structure of a cigarette making and tipping machine includes an adjustable bending arm 1 and an adjustable bending frame 2. A height fine-tuning component is vertically installed on the adjustable bending frame 2, and a height coarse-tuning component is vertically installed on the adjustable bending arm 1. The top of the height fine-tuning component abuts against the adjustable bending arm 1, and the top of the height coarse-tuning component abuts against the bottom surface of the glue cylinder.

[0021] The adjustable bending frame 2 is used to support the adjustable bending arm 1 and adjust the height of the adjustable bending arm 1 through the height fine-tuning component, so as to realize the fine adjustment of the pressing force on the glue cylinder. The adjustable bending arm 1 is used to support the glue cylinder and adjust the pressing force on the glue cylinder through the height coarse-tuning component thereon. The height coarse-tuning component can realize the rapid adjustment of the pressing force on the glue cylinder and is suitable for adjustment in the shutdown state and cannot be used when the equipment is working. The height fine-tuning component can realize the fine adjustment of the pressing force on the glue cylinder, with a slow adjustment speed and high adjustment accuracy, and can also be used in the working state of the equipment.

[0022] In a specific implementation mode, a first mounting hole 3 is horizontally opened at one end of the adjustable bending arm 1, a second mounting hole 4 is vertically opened in the middle of the other end of the adjustable bending arm 1, a receiving groove 5 is opened on the adjustable bending arm 1, the receiving groove 5 and the second mounting hole 4 are located at the same end, and the receiving groove 5 is located on one side of the second mounting hole 4.

[0023] The adjustable bending arm 1 is rotatably installed on the frame of the cigarette making and tipping machine through the cooperation of a pin shaft and the first mounting hole 3.

[0024] Further, the height coarse adjustment component includes an adjustment screw rod 6 and a first adjustment end cap 7. The first adjustment end cap 7 is fixedly provided at the lower end of the adjustment screw rod 6. A spherical end head 8 is formed at the top end of the adjustment screw rod 6. The second mounting hole 4 is a threaded hole, and the adjustment screw rod 6 is threadedly connected to the second mounting hole 4. When it is necessary to quickly adjust the pressing force on the glue cylinder, use a wrench to rotate the first adjustment end cap 7 at the lower end of the adjustment screw rod 6.

[0025] To prevent the adjustment screw rod 6 from automatically rotating due to the vibration of the equipment during operation, it is preferably that a locking nut 9 is threadedly connected to the adjustment screw rod 6. After the height of the adjustment screw rod 6 is adjusted, by rotating the locking nut 9, the bottom surface of the locking nut 9 abuts against the top surface of the adjustment bent arm 1, so that the adjustment screw rod 6 will not automatically rotate due to the vibration of the equipment.

[0026] Further, one end of the adjustment bent frame 2 forms a mounting plate 10, and the other end of the adjustment bent frame 2 forms a third mounting hole 11. The third mounting hole 11 is a stepped hole with a larger upper part and a smaller lower part. The mounting plate 10 is perpendicular to the adjustment bent frame 2, and two circular through holes are provided on the mounting plate 10. The mounting plate 10 is fixed to the frame of the capper through a bolt assembly. In this embodiment, the adjustment bent frame 2 is perpendicular to the adjustment bent arm 1, and the upper end of the height fine adjustment component on the adjustment bent frame 2 abuts against the top plate of the receiving groove 5 on the adjustment bent arm 1.

[0027] Further, the height fine adjustment component includes an adjustment screw 12, a disc spring 13 and an adjustment nut 14.

The lower end of the adjustment screw 12 passes through the third mounting hole 11 and is threadedly connected to the adjustment nut 14. The pitch of the adjustment screw 12 is smaller than the pitch of the adjustment screw rod 6. Therefore, fine adjustment can be achieved by rotating the adjustment screw 12. It should be noted that the specific pitch values of the adjustment screw 12 and the adjustment screw rod 6 can be set according to actual requirements, and are not specifically limited in this embodiment.

[0028] Through the setting of the disc spring 13, the disc spring 13 always gives an upward thrust to the end cap of the adjustment screw 12. By rotating the adjustment nut 14, the adjustment screw 12 moves vertically upward or vertically downward without rotating. The inner wall of the third mounting hole 11 is smooth, so that the adjustment screw 12 can move smoothly.

[0029] Working principle of the utility model: In the shutdown state, first use a wrench to rotate the first adjusting end cap 7 to quickly raise or lower the spherical end head 8 at the top of the adjusting screw rod 6. When the pressing force of the spherical end head 8 on the glue cylinder is close to the standard value, stop rotating the first adjusting end cap 7 and lock the adjusting screw rod 6 with the lock nut 9. Then manually rotate the adjusting nut 14. By rotating the adjusting nut 14, move the adjusting screw 12 up or down, so as to change the height of the spherical end head 8 and realize the fine adjustment of the pressing force of the spherical end head 8 on the glue cylinder until the pressing force of the spherical end head 8 on the glue cylinder reaches the standard value.

[0030] During the operation of the equipment, if the glue layer thickness needs to be adjusted, it can be adjusted by rotating the adjusting nut 14.
