Referring to FIGS. 4 to 6 , the embodiment is applicable to operating a tape roll 91. Prior to this, the steps of sleeve the tape roll 91 are as follows. It is worth mentioning that FIGS. 4 to 6 are cross-sectional views corresponding to the cross-sectional depth of the IV-IV line of FIG. 3 , and the mounting portion 54 and the auxiliary reset member 55 should not be shown. However, in order to illustrate the linkage relationship between the guide wall 53, the mounting portion 54, the auxiliary reset member 55 and the hook portion 62, the relative positions of the mounting portion 54 and the auxiliary reset member 55 when viewed from the side are schematically drawn with imaginary lines.

First, referring to FIG. 4 , when the sleeve portion 63 is at the pushed-in position, the sleeve portion 63 contacts the noise reduction roller 3 along the front-rear direction D1.

Next, referring to FIG. 5 , one hand (not shown) grasps the sleeve portion 63, and the other hand (not shown) grasps the housing 1, so that the sleeve portion 63 is driven by the main plate portion 61 to move from the push-in position to the move-out position along the front-rear direction D1. During this process, the main plate portion 61 slides relative to the slide rail 13 along the front-rear direction D1, and the hook portion 62 moves along the front-rear direction D1 and contacts the guide surface 531, so as to drive the guide wall 53 and the hinge portion 51 to be slightly lifted and press the auxiliary reset member 55.

Referring to FIG. 6 , when the sleeve portion 63 is at the removed position relative to the housing 1, the sleeve portion 63 moves away from the noise reduction roller 3 along the front-rear direction D1, and the guide wall 53 and the hinge portion 51 are preloaded and rebounded by the auxiliary reset member 55, so that the locking surface 532 is slightly lowered. At this time, the hand holding the sleeve portion 63 is released, and the hook portion 62 can be locked against the locking surface 532 along the front-rear direction D1, so that the sleeve portion 63 is positioned on the housing 1. At this time, the released hand can take the tape roll 91 again and put the tape roll 91 on the sleeve portion 63.

Referring to FIG. 7 , after the installation is completed, the protective cover 5 is continuously pressed with a loose hand to abut against the tape reel 91 , thereby driving the guide wall 53 and the hinge 51 to slightly lift up and press against the auxiliary reset member 55 , and the hook portion 62 is then separated from the abutment surface 532 , so that the sleeve portion 63 moves along the front-rear direction D1 and contacts the noise reduction roller 3 through the tape reel 91 .

After assembly, the tape roll 91 is stretched so that the free end of the tape roll 91 is adhered to an adhesive surface 92 after abutting against the noise reduction roller 3 and the guide roller 2, so as to perform an adhesive operation (such as sealing a box). In this process, as the tape roll 91 is continuously consumed (the diameter of the tape roll 91 is reduced), the sleeve portion 63 is driven by the main plate portion 61 and moves from the removal position to the insertion position along the front-rear direction D1, so that the tape roll 91 continues to contact the noise reduction roller 3.

Referring to FIG. 2 , FIG. 3 and FIG. 7 , at the same time, since the noise reduction wheel body 31 gradually expands from the side adjacent to the main board portion 61 to the side away from the main board portion 61 , the noise reduction wheel body 31 can surely press against the tape roll 91 to achieve the effect of noise reduction.

In summary, the carton sealing machine of the present invention produces the following effects:

1. By providing the guide wall 53 of the protective cover 5, the hook portion 62 of the gripping seat 6, and the main reset member 64, when the sleeve portion 63 is in the moved-out position, the hook portion 62 is clamped against the clamping surface 532 of the guide wall 53 along the front-rear direction D1, so that the sleeve portion 63 is positioned in the housing 1. The hand that is freed from holding the sleeve portion 63 can further be sleeved on the sleeve portion 63, thereby facilitating the sleeve portion 91 to be sleeved.

Second, by providing the guide ribs 14 and the positioning protrusions 15 of the outer shell 1, and the abutting portions 42 of the cutting blade seat 4, each abutting portion 42 can be slidably disposed between the top wall 11 and the respective guide ribs 14, and can be deformed and abutted between the top wall 11 and the respective positioning protrusions 15, thereby achieving the effect of facilitating the replacement of the cutting blade seat 4.

As described above, the carton sealing machine of the present invention has a simple structure and is easy to operate, and can indeed achieve the purpose of the present invention.
