[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0021] Please see Figure 1-4This utility model provides a technical solution: a paper rolling device for a straw packaging machine, including a support base 1 and a rod 6. The outer wall of the support base 1 has three extensions, each with a limit rod 2 rotatably mounted on it. A roll shaft 3 is installed through the center of the support base 1. The roll shaft 3 carries and winds paper. One end of the roll shaft 3 is fixedly connected to a limit block 10. When the limit block 10 moves up and down on the roll shaft 3, it contacts the limit rod 2, thus triggering the limiting function. The support base 1 is in the shape of a "V". A mounting hole is opened at the center of the support base 1. One end of the roll shaft 3 extends through the mounting hole. The limit block 10 is located on the end of the roll shaft 3 furthest from the mounting hole. A sleeve is fitted on the roll shaft 3. A drum sleeve 4 is provided, which can move with the movement of the connecting rod 5. The outer wall of the drum sleeve 4 is provided with three extension ends, and each of the three extension ends is connected to two sets of connecting rods 5 by a pin. The other end of the connecting rod 5 is rotatably connected to the rod body 6. The drum sleeve 4 is a cylindrical shape with open ends. The inner wall of the drum sleeve 4 abuts against the outer wall of the drum shaft 3. The movement of the drum sleeve 4 can drive the connecting rod 5 to rotate and adjust to a specified angle, and drive the arc plate 7 to move to a specified position. The drum sleeve 4 is connected to the rod body 6 through the connecting rod 5. There are three rod bodies 6, and each of the three rod bodies 6 is semi-circular. One end of the rod body 6 abuts against one side of the support seat 1, and one side of the rod body 6 is fixedly connected to the arc plate 7.

[0022] Each of the three extensions of the support base 1 is provided with an adjustment groove 8. Two connecting rods are installed inside the adjustment groove 8, and three through-hole adjustment gaps are provided inside the adjustment groove 8. The sidewall of the locking block 902 abuts against the inner wall of the two outer adjustment gaps to fix the position of the locking block 902 and limit its movement. The adjustment component 9 is inserted into the adjustment groove 8. The adjustment component 9 includes an adjustment block 901, one end of which is connected to the rod body 6. Four spaced-apart locking blocks 902 are provided at one end of the adjustment block 901. The spacing between the four locking blocks 902 is... Two springs 903 are installed between the two sections. The other end of the springs 903 is connected to the connecting block 904. The connecting block 904 is positioned against the opening side of the adjustment groove 8. The adjustment block 901 is connected to the connecting block 904 through the springs 903. The adjustment block 901 and the connecting block 904 are located at the two ends of the opening of the adjustment groove 8, respectively. The arc plate 7 is connected to the adjustment block 901 through the rod 6. Pulling the connecting block 904 causes the springs 903 to be pulled out of the gap of the locking block 902. Then, as needed, the adjustment block 901 is pushed, and the arc plate 7 is moved to the designated position according to the thickness of the paper roll material.

[0023] The paper is carried and wound by the roll shaft 3. The roll shaft sleeve 4 can move with the action of the connecting rod 5. The movement of the roll shaft sleeve 4 drives the arc plate 7 to move to the designated position. The arc plate 7 is connected to the adjusting block 901 through the rod body 6. By pulling the connecting block 904, the spring 903 is pulled out from the gap of the locking block 902. As needed, the adjusting block 901 is pushed to drive the arc plate 7 to move to the designated position, thereby adjusting the thickness of the wound paper, ensuring the stability of the paper roll, and completing the paper rolling task efficiently and accurately, while facilitating user adjustment and maintenance.
