[0023] In the present invention, the flat straight-laid laser paper coming out of the laser paper roll is introduced into the feeding component 1. The feeding component 1 can provide power for the laser paper to enter the subsequent bending component 2 and stabilize its travel path to ensure that the laser paper enters the bending component 2 smoothly. The bending component 2 bends the laser paper inside it into a cylindrical shape by virtue of its own shape.

[0024] It should be noted that, starting from the feed end 51 in the first tube section 5, the internal space gradually shrinks until it reaches the circular opening at the discharge end 52. As the laser paper is pushed forward, it is forced to bend into a cylindrical shape due to the internal shape restriction.

[0025] It should be noted that the notch of the second pipe section 6 is connected to the notch of the first pipe section 5 and their sizes are the same.

[0026] In an optional embodiment, the feeding assembly 1 includes a feeding platform 3 and a power assembly 4, the feeding platform 3 includes a first support column 31 and a platform 32, the first support column 31 is arranged at the bottom of the four end points of the platform 32, and the platform 32 is arranged below the laser paper extending from the laser paper roll.

[0027] It should be noted that multiple rows of rollers can be laid above the feeding platform 3 to make the transition of the laser paper smoother when passing through. A rubber friction pad can be set at the bottom of the first support column 31 to play a stabilizing role during operation and prevent displacement due to collisions caused by external reasons during production.

[0028] In an optional embodiment, the power component 4 is arranged at both ends of the laser paper and includes a second support column 41, and the inner side of the second support column 41 is provided with a rotation transmission shaft 42. The rotation transmission shaft 42 is symmetrically arranged in a pair, and a pressure roller 43 is provided at one end of the inner side of the rotation transmission shaft 42.

[0029] It should be noted that the self-rotating transmission shaft 42 is designed to be symmetrical up and down, with a small gap in the middle. After the laser paper comes out of the laser paper roll, it is docked in the middle of the two self-rotating transmission shafts 42. The upper self-rotating transmission shaft 42 rotates counterclockwise, and the lower self-rotating transmission shaft 42 rotates clockwise. The upper and lower pressure rollers 43 clamp the two side edges of the laser paper and move forward. A circle of rubber pads or towel cloth can be installed around the pressure roller 43. While achieving a better clamping effect, it can also ensure that the laser paper will not be damaged due to slight deviations in the installation of the pressure roller 43 when the laser paper is clamped.

[0030] In an optional embodiment, six second support columns 41 are provided, with two of each forming a pair and symmetrically arranged.

[0031] It should be noted that the provision of multiple second support pillars 41 can ensure that the laser paper is evenly stressed during the forward movement.

[0032] In an optional embodiment, a bonding device 8 is provided above the notch of the second pipe section 6, and the bonding device 8 includes a fourth support column 9. There are two fourth support columns 9 and they are arranged on the second pipe section 6 on both sides of the notch and are symmetrically arranged.

The center position of the laser paper is supported by the platform 32. Driven by the pressure roller 43, the laser paper advances into the first tube section 5. It is compressed in the first tube section 5 and becomes cylindrical. It then passes through the second tube section 6. The adhesive 10 aligns with the seams of the laser paper and adheres them together. Finally, the fixed cylindrical laser paper emerges from the end of the second tube section 6.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
