Description

Technical Field

[0001] The utility model relates to the technical field of cigarette packaging equipment, in particular to a strip transparent paper anti-retraction structure used for a packaging machine. Background Art

[0002] When the packaging machine is running for a long time, the strip of transparent paper may move backward during the transportation process, which will have an adverse effect on the subsequent packaging quality and production efficiency. In order to solve the problem of the strip of transparent paper moving backward, the existing packaging machine is usually installed with a stop structure to prevent the strip of transparent paper from moving backward during the transportation process.

[0003] In the actual production process, the existing anti-recoil structure generally controls the anti-recoil roller to fall and press the strip of transparent paper through the linkage of the torsion spring and the rocker arm installed on the rotating rod, so as to achieve the anti-recoil effect of the strip of transparent paper. However, due to the long-term operation of the anti-recoil structure, the anti-recoil roller may fall too quickly or pause due to loosening and aging of the firmware, thereby causing inaccurate positioning of the strip of transparent paper. Due to the inaccurate positioning of the strip of transparent paper, the subsequent process may result in excessive cutting or crooked cutting, which is not conducive to the control of production costs and the guarantee of production quality.

[0019] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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] like Figure 1 As shown, the structural relationship is as follows: it includes a workbench 1 and a strip of transparent paper 2 placed on the workbench 1, and also includes a transmission shaft 3, a transmission gear 4, an output roller 5, a cam 6, a rotating rod 7, a torsion spring 8, a backstop roller 9, a rocker arm 10, a fixed head 11, a fixed plate 12 and a tension spring 14;

[0021] The transmission shaft 3 is installed on the workbench 1, the transmission gear 4 is installed at the left end of the transmission shaft 3 and is connected to the output end of the motor, the output roller 5 is a columnar structure with a cross section, the output roller 5 is installed on the transmission shaft 3, the cam 6 is installed at the right end of the transmission shaft 3, the rotating rod 7 is installed on the workbench 1, the torsion spring 8 is installed at the left end of the rotating rod 7, the anti-retraction roller 9 is installed on the rotating rod 7, the rocker arm 10 is installed at the right end of the rotating rod 7, the fixed head 11 is fixedly connected to the right side of the rocker arm 10, and is installed and connected to the cam 6, the fixed plate 12 is fixedly connected to the right side of the rocker arm 10, and the tension spring 14 is installed between the fixed plate 12 and the workbench 1.

[0022] Preferably, it further includes an adjusting screw 13 . A threaded hole is provided on the fixing plate 12 . The adjusting screw 13 is threadedly connected to the fixing plate 12 through the threaded hole on the fixing plate 12 .

[0023] Preferably, a straight groove is formed at the upper end of the adjusting screw 13 , and a J-shaped structure is formed at the lower end of the adjusting screw 13 . The upper end of the tension spring 14 is installed and connected to the J-shaped structure at the lower end of the adjusting screw 13 .

[0024] During actual use, the staff can rotate the adjustment screw 13 as needed to increase or decrease the tension of the tension spring 14 on the rocker arm 10 to improve the convenience of operation.

[0025] Preferably, a base 15 is further included, and the base 15 is installed on the workbench 1 and is located below the fixing plate 12 .

[0026] Preferably, a hook is provided on the base 15, and the lower end of the tension spring 14 is installed and connected to the hook.

[0027] Preferably, the tension spring 14 is detachably mounted.

[0028] When used specifically, the following processes are included:

[0029] In the first step, the staff turns the adjusting screw 13 until the tension spring 14 produces a suitable tension, which can make the stop roller 9 fall accurately. The staff turns on the packaging machine, the motor drives the transmission gear 4 to rotate, and the gear 4 drives the transmission shaft 3 to rotate. At this time, the output roller 5 on the transmission shaft 3 rotates at the same time.

[0030] In the second step, the cylindrical surface of the output roller 5 contacts the strip of transparent paper 2, driving the strip of transparent paper 2 to move to the lower process. At this time, the fixed head 11 contacts the high surface of the cam 6, which causes the fixed head 11 to drive the rocker arm 10 to lift upward. At the same time, the rocker arm 10 drives the rotating rod 7 to rotate, and the anti-retraction roller 9 installed on the rotating rod 7 is lifted upward.

[0031] In the third step, the output roller 5 continues to rotate until it reaches the cross-sectional position. At this time, the fixed head 11 contacts the lower surface of the cam 6. Under the dual action of the torsion spring 8 and the tension spring 14, the fixed head 11 quickly drives the rocker arm 10 to fall downward. At the same time, the rocker arm 10 drives the rotating rod 7 to rotate, and the anti-retraction roller 9 installed on the rotating rod 7 falls downward to resist the strip of transparent paper 2.

[0032] The fourth step is that after the packaging machine completes the required workload, the staff turns off the packaging machine.
