Description

Technical Field

[0001] The utility model relates to the technical field of packaging belt processing equipment, in particular to a cutting device. Background Art

[0002] In the industrial production process, when scattered objects are stored in cartons for transportation, if the cartons are not packaged, the objects in the cartons may fall out of the cartons during transportation. Therefore, the cartons are usually packaged with strapping tape to increase the firmness of the package. The packaged cartons are transported to the designated location by the conveying mechanism, and then they need to be cut manually using tools such as scissors when they are unpacked and used. However, since the material of the strapping tape is PET (Polyethylene terephthalate), this material has the characteristics of resistance to stretching, shearing and bending. Therefore, a large cutting force is required to cut it when cutting, which leads to a high labor intensity for the operator, and the use of tools such as scissors has certain safety hazards. Utility Model Content

[0003] The utility model aims to solve the problem that the existing technology uses manual cutting of the strapping tape, which has high labor intensity and low safety factor. The utility model provides a cutting device that can replace the manual method to cut the strapping tape, which can reduce the labor intensity of the operator and improve the safety of the operation.

[0004] In order to solve the above technical problems, the embodiment of the utility model discloses a cutting device for cutting the packing tape on the carton, and the cutting device comprises:

[0005] A mounting frame, on which a conveying surface is provided, and the carton can move along a first direction on the conveying surface;

[0006] A lifting roller is arranged on the downstream side of the conveying surface along the first direction, the lifting roller can rotate around its own axis, and the highest point of the circumferential surface of the lifting roller is higher than the conveying surface;

[0008] The driving mechanism is connected to the cutter and is used to drive the cutter to rotate.

[0009] During use, when the carton is conveyed along the first direction and gradually contacts the lifting roller, the highest point of the circumferential surface of the lifting roller can exert an upward force on the bottom of the carton, causing the bottom of the carton to sag inward, thereby creating a gap between the bottom surface of the carton and the strapping tape on the bottom surface of the carton; then the carton continues to be conveyed along the first direction and approaches the cutter, at which time the drive mechanism drives the cutter to start rotating, and when the strapping tape on the carton moves above the cutter, the cutter cuts off the strapping tape; since there is a gap between the bottom of the carton and the strapping tape, the cutter will not contact the carton and will not damage the carton. Then the carton continues to move along the first direction, and the remaining strapping tapes on the carton contact the cutter in turn until all strapping tapes are cut off. By adopting the above technical solution, the cutting device disclosed in the utility model can automatically cut the strapping tape, which can reduce the labor intensity of the operator and improve the safety of the operation compared to the manual cutting method.

[0036] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0037] like Figure 1 As shown, the embodiment of the utility model discloses a cutting device for cutting the strapping tape 18 on the carton 17, and the cutting device comprises: a mounting frame 1, a lifting roller 3, a cutting knife 4 and a driving mechanism. Figure 5 The upper surface of the mounting frame 1 is the conveying surface 2. When the carton 17 is placed on the conveying surface 2, the carton 17 can be moved along the first direction (such as Figure 5 The lifting roller 3 is arranged on the downstream side of the conveying surface 2 along the first direction. The lifting roller 3 can rotate around its own axis, and the highest point of the circumferential surface of the lifting roller 3 is higher than the conveying surface 2. Specifically, the lifting roller 3 is rotatably connected to the mounting frame 1 through a first rotating shaft (not shown in the figure). Figure 1 , a first clearance opening 19 is provided on the upper surface of the mounting frame 1, and the highest point of the circumferential surface of the lifting roller 3 protrudes from the upper surface from the first clearance opening 19. The cutter 4 is provided on the downstream side of the lifting roller 3 along the first direction, and the cutter 4 can rotate around its own axis. Specifically, the rotation axis of the cutter 4 is parallel to the extension direction of the strapping tape 18 at the bottom of the carton 17. The cutter 4 is a circular cutter 4, and the highest point of the circumferential surface of the cutter 4 is higher than the conveying surface 2 and lower than the highest point of the circumferential surface of the lifting roller 3, and the cutter 4 is used to cut the strapping tape 18. Specifically, the cutter 4 is rotatably connected to the mounting frame 1 through a second rotating shaft (not shown in the figure), and a second clearance opening 20 is also provided on the upper surface of the mounting frame 1, and the highest point of the circumferential surface of the cutter 4 protrudes from the upper surface from the second clearance opening 20. The drive mechanism is connected to the cutter 4, and the drive mechanism is used to drive the cutter 4 to rotate. Specifically, refer to Figure 5 The driving mechanism is a motor 5, and the output end of the motor 5 is connected to the cutter 4 through a connecting rod.

[0038] When using, refer to Figure 5 and Figure 6 When the carton 17 is transported along the first direction and gradually contacts the lifting roller 3, the highest point of the circumferential surface of the lifting roller 3 can cause the bottom of the carton 17 to be concave inward (such as Figure 7As shown), there is a gap between the bottom of the carton 17 and the strapping tape 18 at the bottom. Afterwards, the carton 17 continues to be conveyed along the first direction and approaches the cutter 4 under the conveying action of the conveying surface 2. At this time, the motor 5 drives the cutter 4 to rotate. When the first strapping tape 18 on the carton 17 moves above the cutter 4, the cutter 4 cuts the strapping tape 18. Since the depression at the bottom of the carton 17 will not recover its deformation in a short time, there is a gap between the depression and the strapping tape 18, so the cutter 4 will not contact the carton 17 and will not damage the carton 17. Afterwards, the carton 17 continues to move along the first direction, and the remaining strapping tapes 18 on the carton 17 contact the cutter 4 in turn until all the strapping tapes 18 on the carton 17 are cut. With the above technical solution, the cutting device disclosed in the utility model can automatically cut the strapping tape 18. Compared with the manual cutting method, it can reduce the labor intensity of the operator and improve the safety of the operation.

[0039] Optionally, a protective cover 6 is further included, which is hinged to the mounting frame 1 and can rotate between a first position and a second position. When the protective cover 6 is in the first position, Figure 2 and Figure 3 As shown in FIG. 1 , the protective cover 6 blocks the top of the cutter 4. At this time, the cutter 4 cannot cut the strapping tape 18. When the protective cover 6 is rotated to the second position, as shown in FIG. Figure 4 As shown, the upper part of the cutter 4 is exposed, and when the carton 17 passes through the cutter 4, the cutter 4 can cut the packing belt 18 on the carton 17. Specifically, the material of the protective cover 6 is polyester fiber, which is light in weight and relatively wear-resistant, and can meet the use requirements while increasing the service life.

[0040] Alternatively, if Figure 3 As shown, the protective cover 6 includes a mounting portion 7 and a protective portion 8, wherein the mounting portion 7 is hinged to the mounting frame 1 and the rotation axis of the mounting portion 7 is the same as the rotation axis of the cutter 4, the extension direction of the protective portion 8 is perpendicular to the rotation axis of the mounting portion 7, the first end of the protective portion 8 is connected to the mounting portion 7, and the second end is a free end. When the protective cover 6 is in the first position, as shown in FIG. Figure 5 As shown, the second end of the protective portion 8 faces the side close to the lifting roller 3. At this time, the cigarette box on the conveying surface 2 contacts the second end of the protective portion 8, so that the protective cover 6 rotates from the first position to the second position, thereby exposing the top of the cutter 4 to facilitate the subsequent cutting of the strapping belt 18. When the protective cover 6 is in the second position, as shown in FIG. Figure 4 As shown, the second end of the protective portion 8 faces the side away from the lifting roller 3, and the upper part of the cutter 4 is exposed to facilitate cutting of the strapping belt 18.

[0041] Optionally, refer to Figure 3, and further includes a tension spring 9, one end of which is connected to the mounting frame 1, and the other end is connected to the protective cover 6. The tension spring 9 can apply tension to the protective cover 6 to rotate the protective cover 6 from the second position to the first position around the rotation axis. When the carton 17 leaves the top of the cutter 4, the protective cover 6 rotates from the second position to the first position under the tension of the tension spring 9 to shield the top of the cutter 4, thereby preventing the operator from contacting the cutter 4 and preventing the operator from being injured.

[0042] Alternatively, if Figure 3 As shown, it also includes: a slide bar 11, a slider 12 and a locking bolt 15. Among them, the slide bar 11 is arranged on the mounting frame 1, and the number of the slide bars 11 is two, and the two slide bars 11 are both along the vertical direction (such as Figure 3 The cutter 4 is rotatably arranged on the slider 12, and the slider 12 is provided with two through holes (not shown in the figure) and a threaded hole (not shown in the figure), wherein the axes of the two through holes extend in the vertical direction, and the two slide bars 11 are respectively arranged in the two through holes, and the axes of the threaded holes extend in the horizontal direction (as shown in the figure). Figure 3 The threaded hole extends in the side wall of the through hole. The locking bolt 15 is arranged in the threaded hole and is threadedly connected with the threaded hole. When the locking bolt 15 is locked, the end of the locking bolt 15 abuts against the slide bar 11 to limit the movement of the slide block 12 in the vertical direction.

[0043] By adopting the above technical solution, the position of the slider 12 on the slide rod 11 can be adjusted according to actual conditions to adjust the height of the cutter 4 to meet the use requirements of different occasions.

[0044] Alternatively, if Figure 5 As shown, it also includes a conveying mechanism, which includes a plurality of conveying rollers 16 arranged along a first direction, the highest points of the circumferential surfaces of the conveying rollers 16 jointly form a conveying surface 2, the conveying rollers 16 are used to convey the carton 17 along the first direction, the lifting roller 3 and the cutter 4 are arranged between two adjacent conveying rollers 16, and the size of the carton 17 along the first direction (such as Figure 5 The dimension L1 is larger than the distance between the two conveying rollers 16 (as shown in FIG. Figure 5 (see size L2 in the figure).

[0045] By adopting the above technical solution, by using the conveying roller 16 to convey the carton 17, manpower can be saved and the conveying efficiency and stability can be improved; at the same time, the size of the carton 17 along the first direction is greater than the distance between the two conveying rollers 16, which can ensure that at least one end of the carton 17 is always in contact with the conveying surface 2, so that the conveying roller 16 can apply a force to the carton 17, so that the carton 17 can always keep moving on the cutting device.

[0046] Optionally, the cutting device further includes a detection mechanism (not shown in the figure) and a control system (not shown in the figure). The detection mechanism is arranged on the downstream side of the cutter 4 along the first direction, and the detection mechanism is used to detect whether the protective cover 6 is rotated to the second position. Specifically, the detection mechanism is a photoelectric switch. The control system is electrically connected to the detection mechanism and the motor 5 respectively. When the detection mechanism detects that the protective cover 6 is rotated to the second position, the control system controls the motor 5 to operate to drive the cutter 4 to rotate.

[0047] When in use, when the carton 17 is transported in the first direction and begins to contact the lifting roller 3, as shown in FIG. Figure 5 As shown, at this time, one end of the carton 17 is located on the conveying surface 2, and the other end is located on the lifting roller 3, that is, the carton 17 is tilted as a whole. At this time, the highest point of the circumferential surface of the lifting roller 3 can make the bottom of the carton 17 concave inward, so that there is a gap between the bottom of the carton 17 and the strapping belt 18 at the bottom. After that, the carton 17 continues to be conveyed in the first direction under the conveying action of the conveying surface 2, and the front part of the carton 17 contacts the second end of the protective part 8, as shown in FIG. Figure 6 As shown. As the carton 17 continues to move in the first direction, the carton 17 can apply a force to the second end of the protective portion 8 so that the protective cover 6 rotates from the first position to the second position. At this time, the detection mechanism detects that the protective cover 6 rotates to the second position, and the control system controls the motor 5 to drive the cutter 4 to rotate. Afterwards, as the carton 17 continues to move, the strapping tape 18 at the front of the carton 17 contacts the cutter 4, and the cutter 4 cuts the strapping tape 18. Since there is a gap between the bottom of the carton 17 and the strapping tape 18, the cutter 4 will not contact the bottom of the carton 17 and will not damage the carton 17. Subsequently, the conveying surface 2 continues to convey the carton 17, and the bottom surface of the rear of the carton 17 gradually contacts the lifting roller 3. The lifting roller 3 causes the bottom surface of the rear of the carton 17 to be recessed inward, and a gap is generated between the strapping tape 18 on the rear of the carton 17 and the bottom of the carton 17. When the strapping tape 18 on the rear of the carton 17 contacts the cutter 4, the cutter 4 cuts the strapping tape 18. The same process is repeated until all the strapping tapes 18 on the carton 17 are cut off, and then the carton 17 moves to the downstream side of the lifting roller 3 and the cutter 4 and continues to be transported in the first direction. At this time, the protective cover 6 rotates from the second position to the first position under the action of the tension spring 9, and the top of the cutter 4 is blocked. The detection mechanism does not detect that the protective cover 6 rotates to the second position, and the control system controls the motor 5 to stop running, so that the cutter 4 stops rotating.

[0048] The cutting device disclosed in the utility model can automatically cut the strapping belt 18, which can reduce the labor intensity of the operator and improve the safety of the operation compared to the manual cutting method.

[0049] Although the present invention has been illustrated and described with reference to certain preferred embodiments of the present invention, it should be understood by those skilled in the art that the above contents are further detailed descriptions of the present invention in combination with specific embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. Those skilled in the art may make various changes in form and details, including making several simple deductions or substitutions, without departing from the spirit and scope of the present invention.
