[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-6 The utility model provides an embodiment: a self-adhesive label paper turntable rewinding mechanism, comprising a machine table 1 and a rotation drive unit 10 installed on the top wall of the machine table 1, the output end of the rotation drive unit 10 is installed with an external spline main shaft 3 through a coupling, the top end of the external spline main shaft 3 penetrates the outside of the machine table 1 and is set with a plurality of I-shaped rewinding drums 4 that are in contact with each other on the upper and lower sides, a bending arm 6 is rotatably installed on the top end of the machine table 1 on one side of the external spline main shaft 3, and a vertical shaft 7 is fixed on one side of the top end of the bending arm 6, and a rubber wheel 8 corresponding to the position and number of the I-shaped rewinding drum 4 is installed on the surface of the vertical shaft 7, and the rubber wheel 8 is in contact with the outer wall surface of the I-shaped rewinding drum 4;

[0021] A Z-type connecting rod deflection structure 5 is arranged on the other side of the top of the machine 1, and a tension spring 9 is installed between the movable end of the Z-type connecting rod deflection structure 5 and one end of the bending arm 6. The tension spring 9 is arranged on the top of the machine 1. A control panel 2 electrically connected to the input end of the rotation drive unit 10 is installed on one side of the top of the machine 1;

[0022] The rotation drive unit 10 is turned on through the control panel 2 to start working. The rotation drive unit 10 can provide the power required for the operation of the external spline main shaft 3 and the I-shaped rewinding drum 4. The rotation drive unit 10 drives the external spline main shaft 3 and the I-shaped rewinding drum 4 to rotate, thereby rolling up the paper tape;

[0023] The inner edge of the top of the I-shaped rewinding drum 4 is provided with four equally spaced countersunk holes 401, the bottom of the I-shaped rewinding drum 4 is provided with a calibration column 402 which is concentric with the countersunk holes 401, and the center of the inside of the I-shaped rewinding drum 4 is provided with an inner spline groove 403 for sleeve connection with the outer spline main shaft 3, and the I-shaped rewinding drum 4 is made of a hard plastic material;

[0024] When multiple I-shaped rewinding drums 4 are stacked and mounted on the external spline main shaft 3, the I-shaped rewinding drums 4 are sleeved with the external spline main shaft 3 through the internal spline groove 403, and the top and bottom ends of two adjacent I-shaped rewinding drums 4 are plugged through the calibration column 402 and the countersunk hole 401, so that the multiple I-shaped rewinding drums 4 are stably connected and maintain the same rotation function. Compared with the single rewinding drum method, multiple rewinding drums can process more self-adhesive label paper tapes at the same time;

[0025] A baffle plate for supporting the bottom I-shaped rewinding drum 4 is fixed to one end of the surface of the external spline main shaft 3, and the baffle plate prevents the bottom I-shaped rewinding drum 4 from contacting the table surface;

[0026] The Z-type connecting rod deflection structure 5 includes a square seat 501 fixed on one side of the top of the machine 1, and a rotating shaft 502 rotatably installed on one side of the top of the machine 1, a straight arm 503 is rotatably installed on the surface of the rotating shaft 502, one end of the straight arm 503 is hinged to the top of the square seat 501, and the other end of the straight arm 503 is hinged to a pull rod 504, the top of the pull rod 504 is hinged to one end of the bending arm 6, and both ends of the pull rod 504 are fixed with fisheye joints, one end of the tension spring 9 is installed at the bottom end of the straight arm 503, and the other end of the tension spring 9 is installed at the top of the machine 1;

[0027] During the swinging process of the bending arm 6, the straight arm 503 will be pulled by the pull rod 504 to swing counterclockwise, and the tension spring 9 will be stretched, so that the rubber wheel 8 can be more stably pressed against the outer wall of the I-shaped rewinding drum 4. When the external spline main shaft 3 and the I-shaped rewinding drum 4 are running at high speed, this structure can prevent the paper from loosening or shaking, thereby ensuring the stability of the winding process.

[0028] When the embodiment of the present application is in use, the staff first takes out a plurality of I-shaped rewinding drums 4 to be used, so that the plurality of I-shaped rewinding drums 4 are stacked and fitted onto the external spline main shaft 3 in sequence. Before this, the staff needs to manually toggle the vertical shaft 7 so that the vertical shaft 7 and the rubber wheel 8 drive the bending arm 6 to swing until the rubber wheel 8 is no longer close to the external spline main shaft 3, so that the I-shaped rewinding drum 4 and the external spline main shaft 3 can be smoothly fitted. When the plurality of I-shaped rewinding drums 4 have completed the assembly work, the staff will pull the plurality of self-adhesive label paper tapes to be rewound onto the I-shaped rewinding drum 4 and initially wind them on the I-shaped rewinding drum 4. Then, the staff can turn on the rotation drive unit 10 through the control panel 2 to work. The rotation drive unit 10 can provide the power required for the operation of the external spline main shaft 3 and the I-shaped rewinding drum 4. The rotation drive unit 10 drives the external spline main shaft 3 and the I-shaped rewinding drum 4 to rotate, thereby rolling up the paper tape, thereby sorting and collecting the rolled self-adhesive label paper. As the outer diameter of the self-adhesive label paper roll continues to increase, the self-adhesive label paper roll will push the rubber wheel 8 to make the rubber wheel 8 deviate in the direction away from the external spline main shaft 3. Since a tension spring 9 is installed between the bending arm 6 and the Z-type connecting rod deflection structure 5, the tension spring 9 will be in a stretched state. The elastic force generated by the tension spring 9 makes the rubber wheel 8 always press on the outer wall of the self-adhesive label paper roll, ensuring that the paper remains compact during the winding process, and effectively controls the uniform distribution of tension during winding, avoiding loose paper or wrinkles, thereby improving the winding quality and the overall appearance of the product. Each I-shaped rewinding drum 4 in the mechanism is connected through the external spline main shaft 3 to ensure that there will be no axial movement or rotational instability during high-speed operation. At the same time, the winding form of multiple label paper rolls can form multiple paper rolls at the same time, improve production efficiency, and cooperate with the rubber wheel 8, the Z-type connecting rod deflection structure 5, the tension spring 9 and other structures to ensure that the paper will not be offset or misaligned during the winding process, ensuring the stability and consistency of the winding.
