[0002] The coil is a cylindrical plastic film or cloth. After production, it needs to be packaged to prevent collision, wear and other problems during transportation. The existing coil packaging usually adopts a manual packaging method. First, the worker tears off the tape and sticks one end of the packaging film to the outer surface of the coil. Then, the coil is rolled to wrap the packaging film around the coil. After the packaging film completely wraps the coil, the worker uses a cutting tool to cut the packaging film to prepare for the next packaging. During the packaging process, the worker needs to use a variety of cutting tools to cut the tape and packaging film. There is a certain risk in the cutting process. In addition, manual packaging requires a lot of labor costs and has low packaging efficiency.

Detailed implementation manners

[0025] The present invention provides a slitting structure and a pay-off machine. To make the purpose, technical solutions and effects of the present invention clearer and more definite, the following further elaborates on the present invention by way of examples with reference to the accompanying drawings. It should be understood that the specific examples described herein are only used to explain the present invention and are not used to limit the present invention.

[0026] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by terms such as "middle part", "inner side", "outer side", etc. are the orientation or positional relationships of the present invention based on the drawings, and are only for the convenience of describing the present invention and simplifying the description. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features.

[0027] Please refer to Figures 1 to 6, the present invention provides a slitting structure, which includes an upper film rack 1, an adsorption mechanism 2 and a fusing mechanism 3. The adsorption mechanism 2 is arranged on the front side of the upper film rack 1, and the fusing mechanism 3 is arranged on the rear side of the upper film rack 1 in a swingable manner up and down. One or more tape pasting mechanisms 4 that can slide back and forth are arranged below the adsorption mechanism 2. The tape pasting mechanism 4 is rotationally connected to the upper film rack 1. A cutting device 5 is arranged at the front end of the tape pasting mechanism 4, and the cutting device 5 is rotationally connected to the tape pasting mechanism 4.

[0028] In actual application, this slitting structure is a part of the unwinder and needs to be used in cooperation with the unwinder. The unwinder further includes a pushing mechanism 8 for pushing this slitting structure and a rotating mechanism (not shown in the figure) for making the coil roll. When packaging the coil, the upper film rack 1 is pushed above the coil through the pushing mechanism 8. The packaging film of the unwinder enters the upper film rack 1, and the free end of the packaging film extends out of the upper film rack 1 after passing below the adsorption mechanism 2. The adsorption mechanism 2 adsorbs the packaging film to prevent the packaging film from rebounding into the upper film rack 1 during non-working hours, reducing the operating procedures of the unwinder and avoiding the need for workers to load the packaging film onto the machine every time they package. The packaging film is fixedly connected to the surface of the coil through the tape pasting mechanism 4. During the pasting process, the tape pasting mechanism 4 slides forward close to the surface of the coil and adheres the free end of the tape to the surface of the coil. Then, the tape pasting mechanism 4 flips upward close to the adsorption mechanism 2 to make the free end of the tape adhere to the packaging film adsorbed on the adsorption mechanism 2, thereby adhering the packaging film to the surface of the coil. After part of the packaging film is wound around the surface of the coil, the cutting device 5 rotates towards the tape and cuts the tape, preventing all the tape from following the packaging film and winding onto the coil, and also avoiding manual cutting, improving the safety of the packaging process. After the surface of the coil is completely wrapped with the packaging film, the fusing mechanism 3 swings towards the adsorption mechanism 2 and truncates the packaging film located outside the adsorption mechanism 2, thus completing the packaging process of the coil. The automatic cutting of the packaging film is realized through the fusing mechanism 3, improving the safety of the packaging process and also improving the packaging efficiency.

[0029] In one embodiment, the adsorption mechanism 2 can be a vacuum suction pipe.

[0030] In one embodiment, a plurality of anti-collision wheels 21 are arranged at the top of the adsorption mechanism 2 to prevent the upper film rack 1 from colliding with the coil through the anti-collision wheels 21.

[0031] In one embodiment, the pushing mechanism 8 includes a pushing cylinder 81, a slide 82 and a track frame 83, the upper film frame 1 is fixedly connected to the bottom of the slide 82, the slide 82 is matched and installed with the track frame 83, the free end of the pushing cylinder 81 is fixedly connected to the slide 82, the pushing cylinder 81 is installed on the unwinding machine through a top support seat 84, and the track frame 83 is also installed on the unwinding machine; when in use, the free end of the pushing cylinder 81 is extended and retracted to make the slide 82 slide along the track frame 83, so that the upper film frame 1 can adjust the working distance between it and the coil.

[0033] like Figures 1 to 6 As shown, further, the fusing mechanism 3 includes a first swinging device 31 and a first connecting rod 32, there are two first swinging devices 31, the two first swinging devices 31 are respectively arranged on both sides of the upper film frame 1, the two ends of the first connecting rod 32 are respectively connected to the two first swinging devices 31 in transmission, one or more swing arms 33 are distributed on the first connecting rod 32, and a hot melt frame 34 is arranged at the bottom of the swing arm 33; when in use, the first connecting rod 32 is driven to rotate by the first swinging device 31, so that all the swing arms 33 simultaneously drive the hot melt frame 34 to swing toward the bottom of the adsorption mechanism 2, and when the hot melt frame 34 touches the packaging film, the packaging film is melted at the contact position, thereby separating the packaging film from the coil, completing the entire packaging process, and the cut packaging film is re-adsorbed on the adsorption mechanism 2 to prepare for the packaging of the next coil; the above-mentioned setting realizes automatic cutting of the packaging film and reduces labor costs.

[0034] In this embodiment, the first swing device 31 and the first connecting rod 32 are connected by a hinge, that is, they are hinged, and the first swing device 31 is a telescopic cylinder. The telescopic cylinder pushes the hinge by extending and retracting its free end, thereby driving the first connecting rod 32 to rotate, thereby realizing the up and down swing of the swing arm 33 and the hot melt rack 34.

[0035] like Figures 1 to 6As shown in the figure, further, a pressing plate 341 and a hot melt wire 342 are respectively arranged at the bottom of the hot melt frame 34, and the hot melt wire 342 is located below the pressing plate 341; when the hot melt frame 34 swings to below the adsorption mechanism 2, first, the pressing plate 341 presses the packaging film against the adsorption mechanism 2, and then the hot melt wire 342 thermally fuses the packaging film, thereby cutting off the packaging film. The pressing plate 341 avoids the problem of the packaging film shifting during fusing and ensures that the cut packaging film remains adsorbed on the adsorption mechanism 2.

[0036] As Figures 1 to 6 shown in the figure, further, a limit frame 7 is arranged outside the fusing mechanism 3, and both ends of the limit frame 7 are fixedly connected to the upper film frame 1; during use, when the fusing mechanism 3 swings upward to reset, the limit frame 7 is used for stopping to prevent the swing amplitude of the fusing mechanism 3 from being too large; in one embodiment, the limit frame 7 is bolted to the upper film frame 1.

[0038] In this embodiment, the second swing device 6 and the second connecting rod 61 are connected by a hinge, that is, hinged, and the second swing device 6 is a telescopic cylinder. The telescopic cylinder drives the hinge by telescoping its free end, thereby driving the second connecting rod 61 to rotate and realizing the up-and-down swing of the tape pasting mechanism 4.

[0039] As Figures 1 to 6As shown in the figure, further, the tape sticking mechanism 4 includes two fixed seats 41 and a mounting frame 42. The two fixed seats 41 are respectively fixedly connected to the second connecting rod 61. The mounting frame 42 is slidably connected to the two fixed seats 41 respectively. A pushing device 43 is arranged on the outer side of the fixed seat 41. The free end of the pushing device 43 is connected to the mounting frame 42. A tape pressing wheel 44 is arranged at the front end of the mounting frame 42. The cutting device 5 is arranged on the mounting frame 42 and is located below the tape pressing wheel 44. By pushing and pulling the mounting frame 42 through the pushing device 43, the front and back movement of the tape pressing wheel 44 is realized. When the tape pressing wheel 44 abuts against the surface of the coil or the adsorption mechanism 2, the tape attached to the tape pressing wheel 44 is pressed onto the surface of the coil or the adsorption mechanism 2, thereby completing the bonding of the coil and the packaging film.

[0040] In one embodiment, a tape cassette 48 for placing a tape roll is arranged at the rear end of the mounting frame 42. The tape pulled out from the tape roll adheres to the tape pressing wheel 44 for use during packaging.

[0041] In one embodiment, a rotatable conducting roller 47 is arranged inside the mounting frame 42. The tape is guided to the tape pressing wheel 44 through the conducting roller 47.

[0044] As Figures 1 to 6 shown in the figure, further, the cutting mechanism includes a serrated knife 51 and a rotating device 52. The rotating device 52 is arranged on one side of the tape pressing wheel 44. The serrated knife 51 is arranged below the tape pressing wheel 44. The serrated knife 51 is in transmission connection with the rotating device 52. During use, the rotating device 52 drives the serrated knife 51 to rotate, thereby completing the cutting of the tape. There is no need for workers to cut with tools, improving the safety of use. In one embodiment, the rotating device 52 can be a rotary cylinder.

[0045] As Figures 1 to 6 shown in the figure, further, a stop plate 45 is arranged at the top of the mounting frame 42. The stop plate 45 is movably connected to the mounting frame 42 and is in contact with the tape pressing wheel 44. When the tape is cut by the serrated knife 51, there will be a problem of tape rebound. Therefore, the tape is pressed tightly between the stop plate 45 and the tape pressing wheel 44 through the stop plate 45 to avoid the problem of tape rebound.
