[0027] The present invention will be further described below in conjunction with the accompanying drawings.

[0028] like Figures 1 to 3As shown, a strapping cutting device according to an embodiment of the present invention includes a base 1, a guide rail 21, a first slide 22, a second slide 23, a limiting assembly 3, a cutting assembly 4 and an adjusting assembly 5. The guide rail 21 is arranged on the surface of the base 1, the first slide 22 and the second slide 23 are both arranged on the guide rail 21, the limiting assembly 3 is connected to the first slide 22, the cutting assembly 4 is connected to the second slide 23, the adjusting assembly 5 includes a first adjusting block 51, a second adjusting block 52 and an adjusting bolt 53, the first adjusting block 51 is arranged on the limiting assembly 3, the second adjusting block 52 is arranged on the cutting assembly 4, the adjusting bolt 53 is threadedly connected to the second adjusting block 52, and one end of the adjusting bolt 53 abuts against the first adjusting block 51.

[0029] Before cutting the strapping tape 200, the distance between the first adjustment block 51 and the second adjustment block 52 can be adjusted by screwing the adjustment bolt 53. Since the first adjustment block 51 is connected to the limit assembly 3 and the second adjustment block 52 is connected to the cutting assembly 4, the relative position between the limit assembly 3 and the cutting assembly 4 can be adjusted, thereby determining the cutting depth and preventing the cutting assembly 4 from damaging the material inside the packaging box 100. By making the packaging box 100 and the cutting assembly 4 move relative to each other, efficient cutting of the strapping tape 200 on the surface of the packaging box 100 can be achieved, which not only improves the cutting efficiency, but also significantly improves the safety of the operation.

[0030] like Figure 3 As shown, an adjusting nut 54 is further provided on the side of the adjusting bolt 53 away from the first adjusting block 51. The adjusting nut 54 can play a tightening effect. When the adjusting bolt 53 is adjusted into place, by tightening the adjusting nut 54, the adjusting bolt 53 can be better fixed on the second adjusting block 52, thereby improving its stability.

[0031] like Figure 3 and Figure 4 As shown, the strapping cutting device of this embodiment also includes a buffer assembly 6, which includes a first mounting seat 61, a first guide member 62 and a first elastic member 63. One end of the first guide member 62 is arranged on the second adjustment block 52, and the other end of the first guide member 62 passes through the first mounting seat 61 and is slidably connected to the first mounting seat 61. The first elastic member 63 is sleeved on the first guide member 62 and is located between the first mounting seat 61 and the second adjustment block 52.

[0032] In this embodiment, the first elastic member 63 is an elastic sleeve, and when the second adjustment block 52 moves to the side away from the first adjustment block 51, the first elastic member 63 will be compressed, thereby providing a certain buffer. When the strapping tape 200 on the packaging box 100 is cut, the cutting assembly 4 will pass through the surface of one side of the packaging box 100, but the distance between each side of the packaging box 100 and the cutting assembly 4 is usually not equal everywhere, that is, the cutting assembly 4 may be able to cut the first strapping tape 200 well, but cannot contact the second strapping tape 200, or vice versa.

[0033] However, after the buffer assembly 6 is provided, the limiting assembly 3 and the cutting assembly 4 can float within a certain range. When the side distance of the packaging box 100 is relatively close, the first elastic member 63 is compressed, and the limiting assembly 3 and the cutting assembly 4 move backward to avoid excessive cutting depth. When the side distance of the packaging box 100 is relatively far, the first elastic member 63 can push the second adjustment block 52 to move the limiting assembly 3 and the cutting assembly 4 forward, so that the cutting assembly 4 can still contact the strapping tape 200 and complete the cutting of the strapping tape 200.

[0034] like Figure 3 and Figure 4 As shown, the strapping cutting device further includes a first driving assembly 7, which is disposed on the surface of the base 1, and is connected to the first mounting seat 61 and drives the limiting assembly 3 and the cutting assembly 4 to move. The first driving assembly 7 in this embodiment is a cylinder, which can adjust the initial positions of the cutting assembly 4 and the limiting assembly 3 to meet the needs of the actual cutting operation.

[0035] like Figure 1 and Figure 2 As shown, the strapping tape cutting device further includes a second driving assembly 8, on which the base 1 is disposed, and the second driving assembly 8 causes the base 1 to reciprocate in a direction perpendicular to the guide rail 21. The second driving assembly 8 includes a second motor 81, a reducer 82, and a slide 83. The second motor 81 drives the reducer 82 to drive the slide 83, and the slide 83 drives the base 1 to move and causes the limiting assembly 3 and the cutting assembly 4 on the base 1 to pass through the side of the packaging box 100, thereby cutting the strapping tape 200.

[0036] like Figure 3 and Figure 4As shown, the limiting assembly 3 includes a second mounting seat 31, a mounting plate 32 and a limiting roller 33. The second mounting seat 31 is arranged on the surface of the first slide 22, the mounting plate 32 is arranged at the end of the second mounting seat 31, and the limiting roller 33 is arranged on the mounting plate 32. Since the limiting assembly 3 needs to contact the surface of the packaging box 100, in order to facilitate movement, the part of the limiting assembly 3 that contacts the packaging box 100 is set in the form of a roller, and the number of the limiting rollers 33 is multiple. The limiting assembly 3 can significantly improve the stability of the strapping cutting device when it moves on the surface of the packaging box 100, and can reduce the impact of the packaging box 100 on the cutting assembly 4.

[0037] like Figure 3 and Figure 4 As shown, the cutting assembly 4 includes a fixing frame 41, a first motor 42 and a cutting blade 43. The fixing frame 41 is arranged on the second slide 23, the first motor 42 is arranged on the fixing frame 41, and the cutting blade 43 is arranged at the output end of the first motor 42 and is located above the limiting roller 33. The second adjustment block 52 is arranged on the fixing frame 41, so that the position of the cutting assembly 4 can be adjusted by the second adjustment block 52. The first motor 42 drives the cutting blade 43 to rotate to cut the strapping tape 200.

[0038] like Figure 3 As shown, the first adjustment block 51 is also provided with a second guide member 55, and one end of the second guide member 55 away from the first adjustment block 51 passes through the second adjustment block 52 and is slidably connected to the second adjustment block 52. When the first adjustment block 51 moves relative to the second adjustment block 52, the second guide member 55 can slide on the second adjustment block 52 to play a guiding role, thereby improving the stability of the first adjustment block 51 and the second adjustment block 52 during relative movement. In addition, the end of the second guide member 55 away from the first adjustment block 51 is enlarged to play a limiting role, thereby preventing the first adjustment block 51 and the second adjustment block 52 from being too far apart.

[0039] Furthermore, a second elastic member 56 is sleeved on the surface of the second guide member 55, and the second elastic member 56 is arranged between the first adjustment block 51 and the second adjustment block 52. By arranging the second elastic member 56, the limiting roller 33 in the limiting assembly 3 can protrude from the cutting blade 43 before the cutting operation. When the first driving assembly 7 moves the limiting assembly 3 and the cutting assembly 4 forward, the limiting roller 33 can first contact the surface of the packaging box 100, and the second elastic member 56 provides a buffering effect, which greatly reduces the impact during contact. With the compression of the second elastic member 56, the limiting assembly 3 as a whole retracts until the first adjustment block 51 contacts the adjustment bolt 53, at which time the cutting blade 43 enters the cutting position to cut the strapping tape 200.

[0040] like Figure 1 and Figure 2As shown, a protective cover 9 is also provided on the base 1, and an opening 91 is provided on one side of the protective cover 9 for the limit assembly 3 and the cutting assembly 4 to protrude from the protective cover 9. The protective cover 9 can wrap most of the cutting assembly 4 inside it, thereby reducing the risk to the operator and improving safety.

[0041] like Figure 5 As shown, an embodiment of the present invention also provides a method for using a packing tape cutting device, comprising the following steps:

[0042] S1, rotating the adjusting bolt 53, adjusting the distance between the first adjusting block 51 and the second adjusting block 52, so that the relative position between the cutting blade 43 and the limiting roller 33 meets the requirements of the cutting operation;

[0043] S2, adjusting the first driving assembly 7 to adjust the cutting assembly 4 to the cutting position;

[0044] S3, starting the first motor 42 to rotate the cutting blade 43, so that the second driving assembly 8 drives the base 1 to move, and the cutting blade 43 cuts the strapping tape 200.

[0045] Since the relative position between the limiting assembly 3 and the cutting assembly 4 determines the cutting depth, the appropriate cutting depth can be set by rotating the adjusting bolt 53 to prevent the cutting assembly 4 from damaging the material inside the packaging box 100. The first driving assembly 7 moves the limiting assembly 3 and the cutting assembly 4 toward the packaging box 100 and contacts the surface of the packaging box 100. When the first motor 42 rotates the cutting blade 43, the second driving assembly 8 drives the base 1 to move, and the cutting blade 43 passes over the surface of the packaging box 100 and cuts the strapping tape 200.

[0046] Compared with the manual operation of cutting the strapping tape 200 , the use method of the strapping tape cutting device of this embodiment can greatly improve the cutting efficiency and safety.

[0047] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced by equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there are no structural conflicts.
