However, existing technologies often suffer from the following issues: First, the tension distribution between the upper and lower rollers is difficult to precisely control, which can easily lead to localized excessive or insufficient tension during the threading process, causing wrinkles, deviation, and even breakage of the transparent paper. Second, adjusting the tension of the transparent paper often relies on manual intervention, which is not only time-consuming and labor-intensive, but also difficult to achieve real-time, precise dynamic control, impacting production continuity and stability.

[0021] The technical solution of the present invention is described in detail below with reference to the accompanying drawings. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solution of the present invention, and cannot be interpreted as limiting the technical solution of the present invention.

[0022] See also Figures 1 to 5 As shown, the present application provides a transparent paper threading auxiliary tensioning device for a packaging machine, including a fixed connecting rod 1, and two fixed discs 3 are installed on the fixed connecting rod 1 through two connecting parts 2; the fixed connecting rod 1 is a rectangular horizontal plate, and a first threaded hole is provided near each end of the fixed connecting rod, and the connecting part is threadedly connected to the first threaded hole. The fixed disc 3 includes a cylindrical side wall 31 and a disc bottom 32 that closes one end of the cylindrical side wall, and a second threaded hole 33 is provided on the disc bottom 32. The connecting part is threadedly connected to the second threaded hole after passing through the first threaded hole.

[0023] In this application, the two fixed discs have the same structure and size, and can match the upper and lower pulling roller shaft ends of the transparent paper packaging machine. The shaft ends of the upper and lower pulling shafts here refer to the upper and lower pulling rollers No. 8 and No. 9 of the ZB48 transparent paper threading auxiliary tensioning device for traction.

[0024] In this application, the outer surface of the cylindrical side wall 31 of the fixed disc 3 is provided with a carbide hard alloy layer. Each fixed disc is connected to the corresponding pulling roller shaft end through a high-precision bearing to ensure that the fixed disc can provide stable, frictionless support and guidance for the transparent paper during the adjustment and rotation of the pulling roller. The carbide hard alloy layer improves the wear resistance and low friction coefficient of the fixed disc.

[0025] In the present application, the thickness of the disc bottom is greater than the depth of the groove 34 of the fixed disc, wherein the groove 34 is used to place a high-precision bearing.

[0026] In the present application, the fixed connecting rod includes a connecting rod body and semicircular portions provided at both ends of the connecting rod body, and the diameter of the semicircular portion is the same as the outer diameter of the fixed disc. The connecting rod body of the present application is a high-strength horizontal plate, which is intended to form a rigid tension transmission path to ensure that the tension of the transparent paper between the upper and lower pulling rollers is evenly and stably distributed. By adjusting the adjustable connecting mechanism, the operator can accurately set the connection height between the connecting rod and the fixed disc to adapt to the optimal threading tension requirements of different transparent paper materials. In addition, the connection method of the fixed connecting rod can effectively suppress the vibration of the fixed disc during operation, further improving the stability of tension control.

[0027] In the present application, the first threaded hole is arranged at the midpoint of the intersection of the connecting rod body and the semicircular portion to ensure the stability of the fixed disc.

[0028] In the present application, the connector 2 includes a combination of a screw, a nut and a gasket in an integrated structure.

[0029] How it works:

[0030] After the operator unwinds the transparent paper from the roll holder, it is pulled sequentially through the auxiliary tensioning device's upper and lower rollers, No. 8 and No. 9. During the paper threading process, the fixed disc assembly and the fixed connecting rod cooperate to achieve efficient and stable tension control for the transparent paper, eliminating the need for frequent manual adjustments.
