Detailed implementation manners

[0024] The present invention provides an unwind head and a packaging machine. To make the objectives, technical solutions and effects of the present invention clearer and more definite, the following further describes the present invention in detail with reference to the accompanying drawings and by way of examples. 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.

[0025] 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 accompanying 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 indicating the quantity of the indicated technical features.

[0026] Please refer to Figures 1 to 5 , the present invention provides an unwind head, including a packaging film guiding mechanism 1, a pushing frame 2 and a film feeding mechanism 3. The pushing frame 2 is arranged on the packaging film guiding mechanism 1, the pushing frame 2 is slidably connected to the packaging film guiding mechanism 1, the film feeding mechanism 3 is arranged at the bottom of the pushing frame 2, one or more tape pasting mechanisms 4 are distributed at the bottom of the film feeding mechanism 3, and the tape pasting mechanism 4 is movably connected to the film feeding mechanism 3; the packaging film guiding mechanism 1 is used to draw the packaging film 8 to the film feeding mechanism 3; the film feeding mechanism 3 is used to wind the packaging film 8 around the coil; the tape pasting mechanism 4 is used to paste the tape to bond the packaging film 8 to the coil.

[0027] In practical applications, this unwinding head is part of a packaging machine and needs to be used in conjunction with the packaging machine. The packaging machine also includes a rotating mechanism for rolling the coil material; the packaging film 8 enters the packaging film guiding mechanism 1, and the packaging film 8 is advanced by rolling the packaging film guiding mechanism 1. The free end of the packaging film 8 passes through the packaging film guiding mechanism 1 and is connected to the upper film mechanism 3. The pushing frame 2 pushes the upper film mechanism 3 to one side of the coil material. The tape pasting mechanism 4 advances towards the coil material and pastes one end of the tape to the surface of the coil material. Then, the tape pasting mechanism 4 rotates towards the upper film mechanism 3 to make the other end of the tape adhere to the packaging film 8, so that one end of the packaging film 8 is relatively fixed to the surface of the coil material. Finally, the rotating mechanism rotates the coil material in cooperation, so that the packaging film 8 is wound around the surface of the coil material. At the same time, when the packaging film 8 starts to wind around the coil material, the tape pasting mechanism 4 cuts off the tape, so that the packaging film 8 rotates with the coil material for automatic winding. After the coil material is packaged, the packaging film 8 is cut off, and the pushing frame 2 retracts to reset the upper film mechanism 3, thus completing the automatic packaging process of the coil material; through the combined use of the packaging film guiding mechanism 1, the pushing frame 2, the upper film mechanism 3 and the tape pasting mechanism 4, the automatic packaging of the coil material is realized, avoiding uneven packaging quality and saving a large amount of labor costs.

[0028] As Figures 1 to 5 shown, further, an adsorption mechanism 5 is provided on one side of the upper film mechanism 3, and the adsorption mechanism 5 is located above the tape pasting mechanism 4; the adsorption mechanism 5 is used to adsorb the packaging film 8; during the period when the packaging film 8 is not wound, the adsorption mechanism 5 adsorbs the free end of the packaging film 8 to prevent the packaging film 8 from being rolled back into the upper film mechanism 3, and the adsorption mechanism 5 plays a role in fixing the free end of the packaging film 8, which is convenient for the tape pasting mechanism 4 to paste the tape on the packaging film 8.

[0029] In this embodiment, the adsorption mechanism 5 can be a vacuum suction pipe, and a vacuum effect is generated through the vacuum suction pipe to adsorb the packaging film 8 and complete the positioning of the packaging film 8 to prevent the packaging film 8 from rebounding into the upper film mechanism 3.

[0030] In one embodiment, one or more anti-collision wheels 51 are provided on the top of the adsorption mechanism 5; the anti-collision wheels 51 are used to prevent the adsorption mechanism 5 from having a hard collision with the coil material.

During the process of the packaging film 8 winding the coil material, the guide rollers 31 roll along with the movement of the packaging film 8, thereby playing a guiding role for the packaging film 8, making the packaging film 8 more smooth during the winding process and preventing the problem of winding disorder.

[0032] As Figures 1 to 5 shown, further, a fusing mechanism 32 that can swing towards the adsorption mechanism 5 is provided on one side of the upper film mechanism 3; the fusing mechanism 32 is used for cutting off the packaging film 8; during use, after the coil material finishes winding the packaging film 8, the fusing mechanism 32 swings downward towards the packaging film 8, and cuts off the packaging film 8 by means of heat fusing, thereby completing the packaging process of the coil material. After the packaging film 8 is cut off, the fusing mechanism 32 swings back, and the free end of the packaging film 8 is adsorbed again by the adsorption mechanism 5 to prevent the packaging film 8 from rebounding into the upper film mechanism 3.

[0033] In one embodiment, the fusing mechanism 32 can be a fusing wire, and the packaging film 8 is subjected to hot melting treatment by heating the fusing wire to generate high temperature, thereby achieving the effect of fusing.

[0034] As Figures 1 to 5 shown, further, the unwinding head further includes one or more first stretching mechanisms 33, the first stretching mechanisms 33 correspond to the tape pasting mechanisms 4 one by one, the first stretching mechanisms 33 are arranged on the upper film mechanism 3, and the free ends of the first stretching mechanisms 33 are in transmission connection with the tape pasting mechanisms 4; the first stretching mechanisms 33 are used for driving the tape pasting mechanisms 4 to rotate; one end of the first stretching mechanism 33 is hinged to the upper film mechanism 3, and its free end is in transmission connection with the tape pasting mechanism 4 through a transmission member (not shown in the figure); during use, the free end of the first stretching mechanism 33 drives the tape pasting mechanism 4 to swing up and down by pushing and pulling one end of the tape pasting mechanism 4, so that the tape pasting mechanism 4 can swing between the coil material and the upper film mechanism 3 to realize the tape pasting action.

[0035] In one embodiment, a pushing device 41 is provided at the bottom of the tape pasting mechanism 4, and the forward and backward sliding movement of the tape pasting mechanism 4 is realized through the pushing device 41, so that the distance between the tape pasting mechanism 4 and the coil material and the upper film mechanism 3 can be adjusted, improving the flexibility of use.

[0036] In one embodiment, the pushing device 41 may be a push-pull cylinder.

[0037] In one embodiment, a cutter 42 that can slide back and forth is provided in the tape sticking mechanism 4, and the tape is cut by the cutter 42 that moves back and forth.

[0038] If Figures 1 to 5 As shown, further, the two sides of the upper film mechanism 3 are respectively provided with second stretching mechanisms 34, and the two second stretching mechanisms 34 are respectively connected to the fuse mechanism 32 in transmission; the second stretching mechanism 34 is used to drive the fuse mechanism 32 to swing up and down; one end of the second stretching mechanism 34 is hinged to the upper film mechanism 3, and its free end is connected to the fuse mechanism 32 in transmission through a transmission member; when in use, the free end of the second stretching mechanism 34 pushes and pulls one end of the fuse mechanism 32, thereby driving the fuse mechanism 32 to swing up and down, so that the fuse mechanism 32 can swing back and forth toward the adsorption mechanism 5, thereby realizing the action of cutting off the packaging film 8.

[0039] In one embodiment, the first stretching mechanism 33 and the second stretching mechanism 34 may be telescopic cylinders.

[0040] If Figures 1 to 5 As shown, further, a winding mechanism 6 is provided on one side of the packaging film guiding mechanism 1; the winding mechanism 6 is used to roll up the packaging film 8; when in use, the packaging film 8 is rolled up on the winding mechanism 6, and the free end of the packaging film 8 extends into the packaging film guiding mechanism 1, and the packaging film 8 is guided to the upper film mechanism 3 through the packaging film guiding mechanism 1; in one embodiment, the winding mechanism 8 can be an air expansion shaft.

[0041] If Figures 1 to 5 As shown, further, a driving mechanism is provided on one side of the packaging film guiding mechanism 1, and the driving mechanism is transmission-connected with the packaging film guiding mechanism 1; the driving mechanism is used to drive the packaging film guiding mechanism 1 to pull the packaging film 8.

[0042] In one embodiment, the packaging film guiding mechanism 1 includes a guide roller group 11, and the guide roller group 11 includes a plurality of guide rollers, and any guide roller is connected to the driving device in a transmission manner. The packaging film 8 is wound around the guide roller group 11, and the packaging film 8 is guided out of the packaging film guiding mechanism 1 step by step through the guide roller group 11, and the guide roller is actively driven to rotate by the driving device, so that the packaging film 8 is transmitted.

[0043] In one embodiment, the driving device may be a motor or a hand wheel, and the packaging film 8 may be retracted and released automatically or manually.

[0044] ​Figures 1 to 5 As shown, further, the pushing frame 2 includes a transmission track 21 and a moving frame 22. The transmission track 21 is fixedly connected to the packaging film driving mechanism 1. The moving frame 22 is cooperatively connected to the transmission track 21. The upper film mechanism 3 is arranged at the bottom of the moving frame 22. During use, the moving frame 22 can slide up and down along the transmission track 21, so as to realize the pressing action of the upper film mechanism 3 and adjust the distance between the upper film mechanism 3 and the coiled material.

[0045] The present invention also provides a packaging machine, including the unwinding head as described above.

[0046] In summary, during use, the packaging film 8 is pulled forward by the packaging film driving mechanism 1. The free end of the packaging film 8 passes through the packaging film driving mechanism 1 and is connected to the upper film mechanism 3. The pushing frame 2 pushes the upper film mechanism 3 to one side of the coiled material. The tape pasting mechanism 4 advances towards the coiled material and pastes one end of the tape onto the surface of the coiled material. Then the tape pasting mechanism 4 rotates towards the upper film mechanism 3, so that one end of the tape is adhered to the packaging film 8 again, so that one end of the packaging film 8 is relatively fixed to the surface of the coiled material. Finally, in cooperation with the rotating coiled material, the packaging film 8 is wound around the surface of the coiled material, thus completing the automatic packaging process of the coiled material. Through the combined use of the packaging film driving mechanism 1, the pushing frame 2, the upper film mechanism 3 and the tape pasting mechanism 4, the automatic packaging of the coiled material is realized, avoiding uneven packaging quality and saving a large amount of labor costs.
