Description

Technical Field

[0001] This invention relates to the field of packaging, and more specifically to a method for cutting and recycling the packaging straps of a packaging box. Background Technology

[0002] In tobacco production enterprises, most of the existing cardboard boxes for packaging tobacco materials are wrapped with long, narrow strips of plastic. Most of these boxes require the packaging strips to be cut and recycled on automated logistics production lines to separate the boxes from the tobacco materials inside, thus facilitating subsequent processing of the tobacco materials.

[0003] Currently, automated equipment for cutting and recycling the packaging tape of such packaging boxes has the main drawback of a high rate of missed cutting of the packaging tape. When the packaging tape cannot be cut automatically in time, the packaging box cannot be automatically detached, which may lead to the risk of interruption of subsequent automated production. For this reason, tobacco factories usually have to arrange for dedicated personnel to be on duty next to this equipment to manually cut and recycle the packaging tape. Some tobacco factories also directly replace the equipment with manual labor due to its low efficiency. Summary of the Invention

[0031] The following will be described in conjunction with Figures 1-6 A packaging tape cutting and recycling device for a packaging box related to the embodiments of the application will be described in detail. It is worth noting that the following embodiments are only used to explain the application and do not constitute a limitation on the application.

[0032] In the embodiments of the application, as Figures 1-6 shown, a packaging tape cutting and recycling device for a packaging box includes a recycling device 3 and a cutting device 1. The recycling device 3 is slidingly arranged on a first side of the packaging box a, used to hook the packaging tape b on the first side and make the packaging tape b on the second side of the packaging box a tight. The cutting device 1 is slidingly arranged on the second side of the packaging box a, used to arrange the packaging tape b on the second side to a preset position and cut. The first side and the second side are two adjacent sides of the packaging box a covered by the packaging tape b.

[0033] In some embodiments, the recycling device 3 includes a force sensor 32, a mounting sleeve 33, and fingers 31. The fingers 31 are arranged on the force sensor 32 through the mounting sleeve 33. The fingers 31 are L-shaped, and have a first guide inclined surface 37 at the bottom of the L-shaped fingers 31. The recycling device 3 further includes a first connecting seat 34, and the force sensor 32 is connected to an external driving device through the first connecting seat 34.

[0034] The cutting device 1 comprises a mounting bracket 35, a detection switch 12, scissors 13, a tape lifting inclined plate 15, pressure rollers 11 are respectively mounted on the front and rear legs of the mounting bracket 35, the tape lifting inclined plate 15 is mounted on the side of the mounting bracket 35 facing the packaging box a and is located between the front and rear pressure rollers 11, the scissors 13 and the detection switch 12 are both arranged on the mounting bracket 35, and the scissors 13 are driven to cut when the detection switch 12 detects that the tape lifting inclined plate 15 is provided with a packaging tape.

[0035] In some embodiments, a plurality of springs 14 are arranged on the side of the mounting bracket 35 away from the packaging box a, and the other ends of the springs 14 are connected with a second connecting seat 36.

[0036] As shown in Figures 1-6 A packaging tape cutting and recycling device for a packaging box comprises a cutting device 1, a tape pressing device 2 and a recycling device 3; the cutting device 1 comprises 3-4 pressure rollers 11, a detection switch 12, scissors 13, 3-4 springs 14 and a tape lifting inclined plate 15, and the recycling device 3 comprises 1-5 fingers 31, a force sensor 32, 1-5 mounting sleeves 33 and a first connecting seat 34.

[0037] As shown in Figures 2-3 The packaging box a is wrapped by 1-5 packaging tapes b, and generally, the packaging box a is paper-based and the packaging tapes b have a certain elasticity. Figures 1-2 When the packaging box a is in place, the cutting device 1 is tightly attached to the y1' position of the side a1 of the packaging box a along the x direction, as shown in Figures 4-5 The pressure roller 11 has a certain gap x1 with the tape lifting inclined plate 15, and the value of x1 is in the range of 1-10 mm, preferably 2-5 mm; when the several pressure rollers 11 are tightly attached to the side a1 of the packaging box a with a certain force, the side a1 of the packaging box a is deformed to a1', so that the packaging tape b and the side a1' form a gap x2, so as to facilitate the second guide inclined surface 15a of the tape lifting inclined plate 15 to lift the packaging tape b and enter the plane 15b along the second guide inclined surface 15a; after the detection switch 12 at the plane 15b detects that the packaging tape b is in place, the scissors 13 are extended and cut the packaging tape b, and the cut packaging tape b is pressed by the tape pressing device 2 to prevent irregular bouncing.

[0038] As shown in Figure 2As shown, the cutting device 1 moves continuously from position y1' on the side a1 of the packaging box a to position y1" so that all the packaging tape b can be cut. Sometimes irregular deformation may occur on the side a1 of the packaging box a. 3 to 4 springs 14 can ensure that the tape-picking plate 15 will neither pierce the packaging box a nor move away from the packaging box a, thereby increasing the reliability of the equipment in cutting the packaging tape b.

[0039] like Figure 1 , Figure 6 As shown, after all the packaging tapes b are cut, the packaging tape b recovery device 3 at the top a2 of the packaging box a moves along the z direction. The bottom surface of the finger 31 contacts the a2 surface of the packaging box a and moves continuously along the y direction from position y3' to position y3". This allows all the packaging tapes b to be hooked and recovered by the finger 31. The finger 31 is L-shaped and has a first guide slope 37 at the bottom of the L-shaped finger 31, which facilitates hooking the packaging tape b. When the surface of a2 is uneven, the finger 31 can slide up and down. 1 to 5 fingers 31 can play a role in neither piercing the packaging box a nor moving away from the packaging box a, thereby increasing the reliability of the equipment in recovering the packaging tape b; that is, before cutting, the finger 31 hooks the packaging tape on the a2 surface, so that the packaging tape on the a1 surface is in a taut state, which makes it easier for the packaging tape on the a1 surface to be positioned by the pick-up plate 15 to the position of the second guide slope 15b.

[0040] When the packaging tape b is not cut, the force sensor 32 connected to the mounting sleeve 33 will output an abnormal signal when the packaging tape b is hooked by the finger 31. The recycling device 3 can also be installed at y3' and y3" on the top of the packaging box a, and move simultaneously towards the middle of the top a2 of the packaging box a to hook and recycle the packaging tape b. The driving device used for the displacement of the cutting device 1, the pressing device 2 and the recycling device 3 can be a motor, a cylinder or a robotic arm. There are no restrictions here, and it can be flexibly selected according to the actual situation.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
