[0021] See also Figure 1 , Figure 2 and Figure 3 An embodiment of the carton sealing machine of the present invention comprises a housing 1, a guide roller 2, a noise reduction roller 3, a cutting blade seat 4, a protective cover 5 and a holding seat 6.

[0022] The housing 1 defines an inner space 10 and includes a top wall 11, two side walls 12 respectively connected to both sides of the top wall 11, a slide rail 13 arranged on one of the side walls 12, two guide ribs 14 respectively arranged on the side walls 12, and two positioning protrusions 15 respectively connected to the side walls 12.

[0023] See also Figure 2 , Figure 3 and Figure 4 The top wall 11 and the side wall 12 together define an opening 16 communicating with the internal space 10. In this embodiment, the top wall 11 has a first wall portion 111 and a second wall portion 112 arranged to be matched with the first wall portion 111. The first wall portion 111 and one of the side walls 12 are integrally formed, and the second wall portion 112 and the other side wall 12 are integrally formed.

[0024] In this embodiment, the positioning protrusions 15 are respectively connected to a side of the guide rib 14 opposite to the opening 16 .

[0025] The guide roller 2 is rotatably disposed between the side walls 12 and adjacent to the opening 16 .

[0026] The noise reduction roller 3 is rotatably disposed between the side walls 12, and has a noise reduction wheel body 31, and a noise reduction shaft 32 that penetrates and is fixedly connected to the noise reduction wheel body 31, and the noise reduction shaft 32 has two shaft portions 321 that are respectively disposed on the side walls 12 and have corresponding positions, so that the noise reduction wheel body 31 can be rotatably sleeved on the shaft portion 321. In this embodiment, the noise reduction wheel body 31 is in a truncated cone shape.

[0027] The cutting blade seat 4 is disposed on the top wall 11 and adjacent to the opening 16 , and has a blade seat body 41 , two abutting portions 42 respectively connected to both sides of the blade seat body 41 and extending in the same direction, and a hand-holding portion 43 connected to the blade seat body 41 and located between the abutting portions 42 .

[0028] The abutting portion 42 can be deformed and abutted against the housing 1. More specifically, each abutting portion 42 can be slidably disposed between the top wall 11 and the corresponding guide rib 14, and can be deformed and abutted between the top wall 11 and the corresponding positioning protrusion 15. It is worth mentioning that by grasping the hand-held portion 43 to deform the abutting portion 42 and detach it from the housing 1, the present invention can achieve the effect of facilitating the replacement of the cutting blade holder 4.

[0029] See also Figure 3 and Figure 4The protective cover 5 is rotatably disposed on the shell 1, and includes a pivot portion 51 rotatably disposed on the shell 1, a cover body 52 fixedly connected to the pivot portion 51, a guide wall 53 fixedly connected to the pivot portion 51 on a side opposite to the cover body 52 and located in the internal space 10, a mounting portion 54 fixedly connected to the pivot portion 51 on a side opposite to the cover body 52 and located in the internal space 10, and an auxiliary reset member 55 disposed between the mounting portion 54 and the top wall 11 and located in the internal space 10.

[0030] The guiding wall 53 has a guiding surface 531 and a locking surface 532 intersecting and connecting the guiding surface 531 .

[0031] The auxiliary reset member 55 constantly provides a preload to keep the guide wall 53 and the mounting portion 54 away from the top wall 11. In this embodiment, the auxiliary reset member 55 is a compression spring.

[0032] The gripping seat 6 is located in the inner space 10 and is movably disposed on the housing 1 along a front-to-back direction D1. The gripping seat 6 includes a main board portion 61 movably disposed on the housing 1 along the front-to-back direction D1, a hook portion 62 fixedly connected to the main board portion 61, a sleeve portion 63 fixedly connected to the main board portion 61 and spaced apart from the hook portion 62 along the front-to-back direction D1, and a main reset member 64 disposed between the main board portion 61 and the housing 1.

[0033] The main plate portion 61 defines a long slot 611 for the noise reduction shaft rod 32 to pass through. In this embodiment, the main plate portion 61 is slidably disposed on the slide rail 13 .

[0034] The sleeve portion 63 can be driven by the main plate portion 61 to move relative to the housing 1 between a pushed-in position and a removed position.

[0035] The main reset member 64 is disposed between the main board portion 61 and one of the side walls 12 of the housing 1, and constantly provides a preload for the sleeve portion 63 to approach the noise reduction roller 3. In this embodiment, the main reset member 64 is a tension spring.

[0036] See also Figures 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, Figures 4 to 6 For the corresponding Figure 3The cross-sectional view obtained by the cross-sectional depth of the IV-IV line should not show the mounting portion 54 and the auxiliary reset member 55, but in order to illustrate the linkage relationship among 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.

[0037] First, see Figure 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-to-back direction D1.

[0038] Next, see Figure 5 , hold the sleeve portion 63 with one hand (not shown) and hold the housing 1 with the other hand (not shown), 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-to-back direction D1. During this process, the main plate portion 61 slides relative to the slide rail 13 along the front-to-back direction D1, and the hook portion 62 moves along the front-to-back direction D1 and contacts the guide surface 531, so as to drive the guide wall 53 and the pivot portion 51 to slightly lift up and press the auxiliary reset member 55.

[0039] See also Figure 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-to-back direction D1, and the guide wall 53 and the pivoting portion 51 are pre-rebounded by the auxiliary reset member 55, so that the abutting surface 532 is slightly lowered. At this time, the hand holding the sleeve portion 63 is released, and the hook portion 62 can be abutted against the abutting surface 532 along the front-to-back 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.

[0040] See also Figure 7 After the installation is completed, the protective cover 5 is continuously pressed by the released hand to abut against the tape roll 91, thereby driving the guide wall 53 and the pivot portion 51 to slightly lift up and press against the auxiliary reset member 55, and the hook portion 62 is separated from the abutting surface 532, so that the sleeve portion 63 moves along the front-to-back direction D1 and contacts the noise reduction roller 3 from the tape roll 91.

[0041] 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 being pressed against the noise reduction roller 3 and the guide roller 2, so as to perform an adhesive operation (e.g., box sealing). During 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 board portion 61 to move from the removal position to the push-in position along the front-rear direction D1, so that the tape roll 91 is continuously in contact with the noise reduction roller 3.

[0042] See also Figure 2 , Figure 3 and Figure 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.

[0043] In summary, the carton sealing machine of the present invention produces the following effects:

[0044] 1. By providing the guide wall 53 of the protective cover 5, the hook portion 62 of the holding seat 6, and the main reset member 64, when the sleeve portion 63 is in the moved-out position, the hook portion 62 is abutted against the abutting surface 532 of the guide wall 53 along the front-to-back direction D1, so that the sleeve portion 63 is positioned in the housing 1. The user does not need to hold the sleeve portion 63, and the freed hand can be further put on the tape roll 91 on the sleeve portion 63, which has the effect of facilitating the putting of the tape roll 91.

[0045] Second, by providing the guide ribs 14 and the positioning protrusions 15 of the housing 1, and the abutting portions 42 of the cutting blade seat 4, each abutting portion 42 can be slidably provided between the top wall 11 and the corresponding guide rib 14, and can be deformed and abutted between the top wall 11 and the corresponding positioning protrusions 15, thereby achieving the effect of facilitating the replacement of the cutting blade seat 4.

[0046] In summary, 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.

[0047] However, the above is only an embodiment of the present invention and should not be used to limit the scope of the present invention. All simple equivalent changes and modifications made according to the claims and description of the present invention are still within the scope of the present invention.
