[0031] Please see Figures 1-4 This utility model provides a technical solution for a paper roll wrapping machine: including a worktable 1, gears 2, belts 3, servo motors 4, clamping structures 5, lower support 501, adjusting rods 502, upper support 503, locking pins 504, rotary springs 505, rotating rods 506, packaging rolls 6, trays 7, clamping blocks 8, electric telescopic rods 9, sliders 10, sliding rods 11, adjusting springs 12, fixing plates 13, bidirectional motors 14, knife handles 15, blades 16, lead screws 17, forward and reverse motors 18, bidirectional screws 19, mounting frames 20, and heat-pressing strips 21.

[0032] The working principle and usage process of this utility model are as follows: First, combined with... Figure 1 and Figure 3 As shown, the tray 7 is fixedly connected to the outer surface of the belt 3 at equal intervals, and the tray 7 has a "T" shaped structure. The inside of the tray 7 is fixedly connected to the slide rod 11, and the diameter of the tray 7 is not greater than the distance between the mounting frame 20 and the mounting frame 20. The outer surface of the slide rod 11 is fitted with an adjusting spring 12, and the left and right sides of the adjusting spring 12 are slidably connected to sliders 10. The upper end of the slider 10 is fixedly connected to a clamping block 8. The inner cylinder of the paper roll is fitted onto the outer surface of the clamping block 8. The clamping blocks 8 slide automatically on the outer surface of the slide rod 11 through the elasticity of the adjusting spring 12, so as to facilitate the automatic adjustment of the distance between the clamping blocks 8 and the clamping blocks 8, which is convenient for supporting and fixing paper rolls of different sizes and facilitating packaging.

[0033] Combination Figure 1 and Figure 2As shown, the clamping structure 5 includes a lower bracket 501, an adjusting rod 502, an upper bracket 503, a locking pin 504, a rotary spring 505, and a rotating rod 506. The lower bracket 501 is fixedly connected to the upper right end of the workbench 1. The adjusting rod 502 is connected through the upper right end of the lower bracket 501, and the upper end of the adjusting rod 502 passes through the interior of the upper bracket 503. The locking pin 504 is integrally fixedly connected to the lower left end of the upper bracket 503, and the locking pin 504 passes through the middle of the packaging roll 6. The rotating rod 506 is rotatably connected to the upper left end of the lower bracket 501. A rotary spring 505 is sleeved on the outer surface of the rotating rod 506. The upper end of the rotating rod 506 passes through the middle of the packaging roll 6. The rotating rod 506 has a "+" shaped structure, and the upper end of the rotating rod 506 is engaged with the opening in the middle of the packaging roll 6. The packaging roll 6 is connected to the rotating rod 506 and the rotary spring 506. Spring 505 forms a rotating structure on the lower bracket 501, and the lower end of the packaging roll 6 is flush with the upper end of the tray 7. Both the upper bracket 503 and the lower bracket 501 form a telescopic structure with the adjusting rod 502, and both the lower bracket 501 and the upper bracket 503 form a disassembly structure with the adjusting rod 502 by bolts. According to the height of the paper roll to be packaged, the upper bracket 503 slides on the adjusting rod 502, and at the same time, the adjusting rod 502 is fixed on the lower bracket 501 and the upper bracket 503 by bolts, which facilitates the installation and fixing of the packaging roll 6 and facilitates packaging. The packaging rolls 6 on the front and rear sides are integrated packaging bags. An electric telescopic rod 9 runs through the middle of the left end of the packaging roll 6. The electric telescopic rod 9 provides limiting support for the packaging roll 6, which facilitates the packaging bag of the packaging roll 6 to wrap the paper roll and facilitates subsequent packaging processing.

[0034] Combination Figure 1 and Figure 4As shown, two fixed plates 13 are symmetrically arranged at the top of the workbench 1, and the fixed plates 13 have a "U" shape. A blade 16 is connected through the opening in the middle of the fixed plate 13, and the blade 16 slides up and down through the handle 15 at the opening of the fixed plate 13. The front and rear outer surfaces of the bidirectional screw 19 are threaded with mounting brackets 20, and the mounting brackets 20 are symmetrically arranged about the horizontal central axis of the workbench 1. The left and right inner walls of the mounting brackets 20 are inlaid with heat-pressing strips 21. When the leftmost tray 7 passes through the fixed plate 13 and is conveyed to the left side of the fixed plate 13, the servo motor 4 stops conveying, and at the same time, the electric telescopic rod 9 retracts and releases the packaging roll 6. The packaging roll 6 is released by the elastic rotation of the rotating rod 506. The packaging roll 6 is wound up to the clamping structure 5. At this time, the bidirectional motor 14 starts to work, driving the bidirectional screw 19 to rotate. The bidirectional screw 19 is threadedly connected to the mounting frame 20, which facilitates the adjustment of the distance between the mounting frames 20 and the packaging roll 6 on the outer surface of the paper roll using the hot pressing strip 21. This makes it easy for the packaging roll 6 to wrap around the outer surface of the paper roll. The power switch of the forward and reverse motor 18 is turned on, and the forward and reverse motor 18 drives the lead screw 17 to rotate, which facilitates the up and down sliding knife handle 15, driving the blade 16 to cut the packaging roll 6. This makes it easy to cut and separate the first packaged paper roll, and then start packaging the next paper roll. This is the working process of the paper roll wrapping machine.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
