[0030] In the present application, the unpacking tool comprises a blade 1, a blade head 2 and a handle 4, wherein the blade head 2 is arranged at one end of the blade body 1 and the handle 4 is arranged at the other end of the blade body 1. A cutting portion 3 is arranged on the blade head 2 and a hand-holding portion is arranged on the handle 4, which is used to limit the position of the operator's hand when the operator holds the handle. The operator holds the unpacking tool by the handle and applies a force to the sealing tape by the cutting portion 3, so that the sealing tape on the cigarette box can be quickly cut and the plastic tape loaded with tobacco can be taken out of the cigarette box; after taking out the plastic tape, the cutting portion 3 applies a force to the cable tie that closes the opening of the plastic bag, so that the cable tie that closes the opening of the plastic bag can be quickly cut and the tobacco can be taken out for use, thereby making the unpacking and use of tobacco more convenient and quick, and improving the production efficiency of cigarettes.

[0031] In this embodiment, the cutting portion 3 includes a tip extending away from the cutter head 2 and a blade 34 extending on one side of the tip. The tip is used to cut the tape, and the blade 34 is used to cut the cable tie. Figure 1 and Figure 3 The cutting portion 3 includes a tip and a blade 34, wherein the tip extends on the blade head 2 in a direction away from the blade head 2, thereby forming an acute-angle spur on the blade head 2. The tip applies force to the sealing tape that seals the cigarette box, so that the sealing tape can be quickly cut open, making it easy to take out the materials loaded in the cigarette box.

[0032] A blade 34 extends from one side of the tip, and the blade 34 applies force to the tie that closes the opening of the plastic bag, so that the tie that closes the opening of the plastic bag can be quickly cut off, thereby facilitating the removal of tobacco from the plastic tie for use, thereby making it more convenient and quick to unpack and use the tobacco, thereby improving the production efficiency of cigarettes.

[0033] In this embodiment, the tip includes a vertical section 31 perpendicular to the blade head 2, and an extension section 32 provided at an end of the vertical section 31 away from the blade head 2, the extension section 32 extends toward the handle 4, a blade 34 is provided inside the vertical section 31 and the extension section 32, and a thorn 33 for cutting the tape is provided at the end of the extension section 32, see Figure 1 and Figure 3 The tip includes a vertical section 31 and an extension section 32 . The vertical section 31 extends vertically outward in a direction away from the cutter head 2 . The extension section 32 is arranged at an end of the vertical section 31 away from the cutter head 2 and extends in a direction of the handle 4 .

[0034] A thorn 33 is provided at the end of the extension section 32. The thorn 33 applies force to the sealing tape that closes the cigarette box, so that the sealing tape can be quickly cut open, making it convenient to take out the materials loaded in the cigarette box; a blade 34 is provided on the inner side of the vertical section 31 and the extension section 32.

[0035] The reason why the tip is set to such a structure is that when the cable tie for closing the opening of a plastic bag is cut, the cable tie can be hooked through the extension section 32 extending toward the handle 4. During the hooking process, the blade 34 located on the inner side of the vertical section 31 and the extension section 32 can cut the cable tie, thereby making the operation of cutting the cable tie for closing the opening of a plastic bag with this tool simpler, more convenient and easier to implement.

[0036] In this embodiment, the hand-held portion is a collar 5 provided on the handle 4, and the collar 5 is used for inserting fingers of the hand. Figure 1 A collar 5 is provided on the knife handle 4. When the operator holds the knife handle 4, the operator inserts the finger into the collar 5 so that the collar 5 limits the finger of the operator. On the one hand, it is convenient for the operator to hold the knife handle 4; on the other hand, it is not easy for the operator's hand to separate from the knife handle 4, so that the operator can hold the knife handle 4 and apply force to the sealing tape of the cigarette box and the cable tie of the plastic bag by the tip of the knife handle 4 more easily, thereby making it more convenient and quick to open the box and use the tobacco, thereby improving the production efficiency of cigarettes.

[0037] It is foreseeable that: the ring 5 provided on the knife handle 4 can be one, and when the operator holds the knife handle 4, one finger of the hand is inserted into the ring 5, so that the ring 5 limits the position of the finger; the ring 5 provided on the knife handle 4 can also be multiple, and when the operator holds the knife handle 4, multiple fingers of the hand are respectively inserted into multiple rings 5, so that the multiple rings 5 ​​respectively limit the position of multiple fingers. In the present application, it is preferred to provide two rings 5 ​​on the knife handle 4, and when the operator holds the knife handle 4, two fingers of the hand are respectively inserted into the two rings 5, so that the two rings 5 ​​respectively limit the position of two fingers.

[0038] In this embodiment, a flexible pad 51 is provided inside the ring 5. Figure 1In the present application, a flexible pad 51 is provided on the inner side of the collar 5, and the fingers of the operator's hand are inserted into the collar 5. When the handle 4 is held, the fingers are in flexible contact with the inner side of the collar 5, so that the operator's hand exerts force, and the operator's fingers are protected when the tip cuts the sealing tape that closes the cigarette box, and the blade 34 cuts the cable tie that closes the plastic bag opening, thereby making it easier to cut the sealing tape and cut the cable tie. In the present application, the flexible pad 51 can be made of flexible materials such as rubber and sponge.

[0039] In this embodiment, the cutting portion 3 is detachably mounted on the cutter head 2. Figure 2 Since the tool cuts the sealing tape of the cigarette box and cuts the cable tie of the plastic bag through the cutting portion 3 of the blade head 2 in direct contact with the sealing tape and the cable tie, the spurs 33 and the blade 34 of the cutting portion 3 will be worn after long-term use, making the operation of cutting the sealing tape and cutting the cable tie time-consuming and laborious.

[0040] Therefore, in the present application, the cutting portion 3 is detachably mounted on the cutter head 2. After the spurs 33 and the blade 34 of the cutting portion 3 are worn, the cutting portion 3 can be removed from the cutter head 2 for replacement, thereby making the operations of cutting the sealing tape and cutting the cable tie time-saving and labor-saving, and reducing production costs.

[0041] In this embodiment, the cutting portion 3 is provided with an inserting block 35, and the cutter head 2 is provided with a first inserting slot 21 for inserting the inserting block 35.

The cutting part 3 can be installed on the cutter head 2 by inserting the insertion block 35 into the first insertion slot 21. When the insertion block 35 is pulled out from the first insertion slot 21, the cutting part 3 can be removed from the cutter head 2, so that when the spurs 33 and the blade 34 of the cutting part 3 are worn after long-term use, the cutting part 3 can be removed from the cutter head 2 for replacement, so that the operation of cutting the sealing tape and cutting the cable tie is time-saving and labor-saving, and the production cost is reduced.

[0042] In this embodiment, the cutter head 2 is provided with a first through hole 22 that connects the two sides of the first plug-in slot 21 with the outside world, and the plug-in block 35 is provided with a second through hole 351. The unpacking tool also includes a first bolt 6 and a first nut 7. One end of the first bolt 6 sequentially penetrates the first through hole 22 on one side of the first plug-in slot 21, the second through hole 351, and the first through hole 22 on the other side of the first plug-in slot 21. The first nut 7 is threadedly connected to one end of the first bolt 6 that penetrates the first through hole 22 on the other side of the first plug-in slot 21. See FIG. Figure 2The cutter head 2 is also provided with a first through hole 22 , which connects the two sides of the first plug-in slot 21 with the outside, and the plug-in block 35 is provided with a second through hole 351 .

[0043] The unpacking tool also includes a first bolt 6 and a first nut 7. When the plug-in block 35 is inserted into the first plug-in slot 21, the first bolt 6 penetrates the first through hole 22 on one side of the first plug-in slot 21, the second through hole 351, and the first through hole 22 on the other side of the first plug-in slot 21 from the outside in sequence. The first nut 7 is screwed to one end of the first bolt 6 that penetrates the first through hole 22 on the other side of the first plug-in slot 21, thereby realizing the fixed installation of the cutting part 3 on the blade head 2. When the operator holds the handle 4 in his hand, the tip of the cutting part 3 can apply a force to the sealing tape that seals the cigarette box to cut the sealing tape, and the blade 34 of the cutting part 3 can apply a force to the cable tie that seals the opening of the plastic bag to cut the cable tie.

[0044] When the tip and blade 34 of the cutting portion 3 are worn after long-term use and the cutting portion 3 needs to be removed from the cutter head 2 for replacement, the first nut 7 is first unscrewed from the first bolt 6, so that the first bolt 6 can be pulled out from the first through hole 22 on the other side of the first plug-in slot 21, the second through hole 351, and the first through hole 22 on one side of the first plug-in slot 21 in sequence, so that the plug-in block 35 can be pulled out from the first plug-in slot 21, thereby realizing the removal of the cutting portion 3 from the cutter head 2.
