The feeding roller 5 is movably connected to the fixed plate 27 through a lifting mechanism, and the front ends of the mounting frame 1 are fixedly connected to extension plates 3 on both sides, and a discharge shaft 10 is provided between the two extension plates 3. A placement groove 28 for accommodating the discharge shaft 10 is provided on the extension plate 3, a feeding mechanism acting on the discharge shaft 10 is provided on the extension plate 3, and a mechanism acting on the discharge shaft 10 is also provided on the extension plate 3. 0's driving mechanism, the feeding mechanism consists of a feeding rod 11, a slider 23, a No. 2 cylinder 24 and a connecting rod 25. The two extension plates 3 are rotatably connected with the connecting rod 25, and the two ends of the connecting rod 25 are fixedly connected with the feeding rod 11. The two feeding rods 11 are parallel to each other, and the sides of the two feeding rods 11 away from each other are rotatably connected with the two extension plates 3 respectively. A card slot 12 is provided on the upper surface of the feeding rod 11, and a slide groove 22 is provided on the lower surface of the feeding rod 11. A slide block 23 is slidably installed in the slide groove 22. A No. 2 cylinder 24 is provided below the feeding rod 11, and the No. 2 cylinder 24 is fixedly connected to the extension plate 3. The end of the telescopic rod of the No. 2 cylinder 24 is rotatably connected to the slide block 23.

[0023] Wherein, both ends of the unloading shaft 10 are respectively provided with clamping rods 26 which are adapted to each other with the clamping grooves 12 .

[0024] When in use, the length of the telescopic rod of the No. 2 cylinder 24 is retracted to rotate the feeding rod 11 downward. When the height of the card slot 12 on the feeding rod 11 from the ground is less than the radius of the paper strip roll, the activity of the telescopic rod of the No. 2 cylinder 24 is stopped. At this time, the feeding shaft 10 is inserted into the axis position of the paper strip roll, and then the paper strip roll is rolled so that the feeding shaft 10 extending from both ends of the paper strip roll moves above the two card slots 12. Then the length of the telescopic rod of the No. 2 cylinder 24 is extended to drive the feeding rod 11 to rotate upward, so that the card rods 26 at both ends of the feeding shaft 10 are embedded in the card slots 12, and then the feeding rod 11 is controlled to rotate upward to lift the feeding shaft 10 and the paper strip. When the feeding rod 11 is rotated to an upwardly tilted position (reference Figure 4 ), the discharge shaft 10 on the feeding rod 11 will roll out of the card slot 12 and roll into the placement slot 28 on the extension plate 3, thereby automatically completing the feeding work of the paper strip roll.

[0025] Among them, the driving mechanism consists of a fixed component and a No. 2 motor 16, and the two fixed components are symmetrically distributed on both sides of the two extension plates 3 away from each other. The fixed component consists of a limit block 14, a fixed vertical plate 15, a guide block 18 and a mounting plate 19. The mounting plate 19 is fixedly connected to the side wall of the extension plate 3, and the mounting plate 19 is a U-shaped structure. The upper end of the mounting plate 19 is provided with a fixed vertical plate 15, and the fixed vertical plate 15 is rotatably connected to the limit block 14 at one end close to the extension plate 3.

The No. 2 motor 16 is fixedly installed on the side wall of the fixed vertical plate 15 of a fixed component, and the No. 2 motor 16 is fixedly connected to the limit block 14.

[0026] When the unloading shaft 10 enters the placement groove 28, the limit block 14 is rotated to align the limit block 14 with the hole shape of the limit groove 13 at the end of the unloading shaft 10. Then, the two limit blocks 14 are controlled to approach each other through the adjustment component until the two limit blocks 14 are respectively inserted into the limit grooves 13 at both ends of the unloading shaft 10. Then, the No. 2 motor 16 is started to drive the limit block 14 to rotate, thereby driving the unloading shaft 10 and the paper strip roll to rotate.

[0027] Among them, the adjustment assembly consists of an adjustment member 20 and a screw 21. The screw 21 passes through the guide block 18 and is connected to the guide block 18 by threaded fitting. The two ends of the screw 21 are respectively rotatably connected between the two parallel plates of the mounting plate 19. The side wall of the mounting plate 19 away from the extension plate 3 is rotatably connected with the adjustment member 20, and the adjustment member 20 is fixedly connected to the screw 21.

[0028] During use, the adjusting member 20 is rotated to drive the lead screw 21 to rotate, thereby controlling the guide block 18 to move along the axial direction of the lead screw 21 , and further controlling the position of the limit block 14 .

[0029] Among them, the lifting mechanism is composed of a movable block 6 and a No. 1 cylinder 8. Both ends of the feeding roller 5 are rotatably connected with a movable block 6. The two movable blocks 6 are respectively slidably installed in the movable grooves 7 opened in the two fixed plates 27. The upper end of the fixed plate 27 is located above the movable block 6 and is fixedly installed with the No. 1 cylinder 8. The telescopic rod of the No. 1 cylinder 8 slides through the upper end of the fixed plate 27 and is fixedly connected to the upper end of the movable block 6. The No. 1 motor 9 is fixedly connected to the side wall of a movable block 6, and the output shaft of the No. 1 motor 9 is fixedly connected to the end of the feeding roller 5.

[0030] During use, by adjusting the length of the telescopic rod of the No. 1 cylinder 8, we can control the movable block 6 to move up and down in the movable groove 7, and then adjust the height of the feed roller 5, control the feed roller 5 to move downward and press the paper strip. At this time, start the No. 1 motor 9 to drive the feed roller 5 to rotate, and the feed roller 5 will push the paper strip toward the bottom of the cutting machine 4.

[0031] A plurality of tensioning rollers 29 are rotatably mounted inside the mounting frame 1 .

[0032] The paper strip roll is pulled so that the end of the paper strip roll passes through a plurality of tensioning rollers 29 in sequence, and then the end of the paper strip roll is placed on the cutting table 2 .

[0033] The utility model provides a paper strip roll automatic feeding and cutting device, the specific working principle is as follows:

[0034] When in use, the length of the telescopic rod of the No. 2 cylinder 24 is retracted to rotate the feeding rod 11 downward. When the height of the card slot 12 on the feeding rod 11 from the ground is less than the radius of the paper strip roll, the activity of the telescopic rod of the No. 2 cylinder 24 is stopped. At this time, the feeding shaft 10 is inserted into the axis position of the paper strip roll, and then the paper strip roll is rolled so that the feeding shaft 10 extending from both ends of the paper strip roll moves above the two card slots 12. Then the length of the telescopic rod of the No. 2 cylinder 24 is extended to drive the feeding rod 11 to rotate upward, so that the card rods 26 at both ends of the feeding shaft 10 are embedded in the card slots 12, and then the feeding rod 11 is controlled to rotate upward to lift the feeding shaft 10 and the paper strip. When the feeding rod 11 is rotated to an upwardly tilted position (reference Figure 4 ), the discharge shaft 10 on the feeding rod 11 will roll out of the card slot 12 and roll into the placement slot 28 on the extension plate 3, thereby automatically completing the feeding work of the paper strip roll.

[0035] Then rotate the limit block 14 to align the limit block 14 with the hole pattern of the limit groove 13 at the end of the discharge shaft 10, and then control the two limit blocks 14 to approach each other through the adjustment component until the two limit blocks 14 are respectively inserted into the limit grooves 13 at both ends of the discharge shaft 10, thereby completing the positioning of the discharge shaft 10.

[0036] Then pull the paper strip roll so that the end of the paper strip roll passes through multiple tensioning rollers 29 in sequence, and then place the end of the paper strip roll on the cutting table 2. By adjusting the length of the telescopic rod of the No. 1 cylinder 8, we can control the movable block 6 to move up and down in the movable groove 7, and then adjust the height of the feed roller 5, control the feed roller 5 to move downward and press the end of the paper strip roll placed on the cutting table 2.

[0037] At this time, motor No. 1 9 and motor No. 2 16 are started at the same time. Motor No. 2 16 will drive the limit block 14 to rotate, thereby driving the unloading shaft 10 to rotate to unload the paper strip roll, and motor No. 1 9 will drive the feed roller 5 to rotate, and the feed roller 5 will push the paper strip toward the bottom of the cutting machine 4.

[0038] The second motor 16 drives the limit block 14 to rotate, thereby driving the unwinding shaft 10 and the paper strip roll to rotate.
