Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] See also Figures 1 to 4As shown, an embodiment of the utility model provides a feeding device 10 for coil material conveying, which includes a frame 100, a carrying device 200, a winding device 300 and a loading device 400; the carrying device 200 is connected to the frame 100; the carrying device 200 includes a material receiving component 210 and a material suction component 220, the material receiving component 210 and the material suction component 220 are arranged opposite to each other, and the material receiving component 210 and the material suction component 220 cooperate to absorb the material in the coil material; the winding device 300 includes a stripping knife component 310 and a winding component 320, the winding component 320 is rotatably connected to the frame 100, the stripping knife component 310 is arranged upstream of the winding component 320, the stripping knife component 310 is used to separate the film layer on at least one side of the coil material, and the winding component 320 is used to wind the film layer; the loading device 400 is rotatably connected to the frame 100, and the loading device 400 is used to fix the coil material.

[0040] When using the feeding device 10 of this embodiment, the coil is first installed on the loading device 400. The stripping knife assembly 310 cooperates with the winding assembly 320, and the stripping knife assembly 310 can separate the film layer of the coil from the coil and rewind it through the winding assembly 320. By setting the material receiving assembly 210 to cooperate with the coil, the material in the coil can be peeled off; when the coil is turned upside down, the material is first adsorbed by the material suction assembly 220 and then adsorbed by the material receiving assembly 210, thereby completing the peeling of the upside-down material.

[0041] In the feeding device 10 of this embodiment, by setting up a winding device 300 to cooperate with the carrying device 200, the coiled material can be automatically conveyed and the material stripping operations can be performed, and it can be compatible with both forward and reverse incoming materials, with high stripping efficiency and good use effect.

[0042] It should be noted that, in the roll material mentioned in the present application, the roll material may have at least one film layer, which is usually used to seal the material on the roll material. Of course, when the roll material includes two film layers, the two film layers can be located on opposite sides of the roll material, one of which can be used as a protective film and the other can be used as a base film.

[0043] In one embodiment, the stripping knife assembly 310 includes a separation stripping knife 311 and a moving mechanism 312. The moving mechanism 312 is arranged on a side of the frame 100 away from the material receiving assembly 210. The separation stripping knife 311 is connected to the output end of the moving mechanism 312 and is used to drive the separation stripping knife 311 to move relative to the frame 100; the material receiving assembly 210 is connected to the separation stripping knife 311 and is spaced apart from the separation stripping knife 311 to form a channel for conveying the film layer.

[0044] According to the configuration, when the coil moves to the stripping knife assembly 310, the coil contacts the separation stripping knife 311, and at this time the separation stripping knife 311 can peel off the film layer on the coil so that the material can be separated from the coil and fixed by adsorption through the material receiving assembly 210; at this time, the film layer is transported from the channel toward the winding assembly 320 and is wound through the winding assembly 320, and at this time the winding assembly 320 can be used as a power source for winding to drive the coil to move; by setting a moving mechanism 312 to drive the separation stripping knife 311, the moving mechanism 312 can adjust the relative position between the separation stripping knife 311 and the feeding device 400, or adjust the tension of the coil.

[0045] Specifically, the moving mechanism 312 includes a moving drive member 3121, a moving screw rod 3122 and a moving block 3123. The moving drive member 3121 is arranged on the frame 100, the moving screw rod 3122 is connected to the output end of the moving drive member 3121, the moving block 3123 is transmission-connected to the moving screw rod 3122, and the moving block 3123 is connected to the separation stripping knife 311 and is used to drive the separation stripping knife 311 to move relative to the frame 100. In other embodiments, the moving mechanism 312 can also be a linear moving module, which is not the only limitation here.

[0046] Furthermore, the stripping knife assembly 310 also includes a reverse stripping knife 313, which is arranged between the loading device 400 and the supporting device 200, and the reverse stripping knife 313 is used to separate at least one of the film layers; the winding assembly 320 includes a first winding roll 321 and a second winding roll 322, and the first winding roll 321 and the second winding roll 322 are respectively rotatably connected to the frame 100, and the first winding roll 321 is arranged downstream of the separation stripping knife 311, and the second winding roll 322 is arranged downstream of the reverse stripping knife 313; the winding assembly 320 also includes a winding drive 323, which is connected to the frame 100 and is used to drive the first winding roll 321 and / or the second winding roll 322 to rotate.

[0047] Thus, when the coil has a film layer, when the film layer is located on the side facing the reverse stripping knife 313, the reverse stripping knife 313 can be used to strip the film layer; when the film layer is located on the side facing the separation stripping knife 311, the separation stripping knife 311 can be used to strip the film layer. By arranging the separation stripping knife 311 and the reverse stripping knife 313 to cooperate, the feeding device 10 can realize the function of stripping the film layer of the coils of two different feeding methods. Of course, when the coil has two film layers, the two film layers can be stripped by the separation stripping knife 311 and the reverse stripping knife 313 respectively, and the functionality is improved.

[0048] After the film layer of the coil is peeled off by the separation stripping knife 311 and the reverse stripping knife 313 respectively, it can be wound up by the first winding roll 321 and the second winding roll 322 respectively. By setting the winding drive member 323 to cooperate with the first winding roll 321 and / or the second winding roll 322 respectively, the rotation function of the first winding roll 321 and / or the second winding roll 322 can be realized, and the winding efficiency can be further improved. Of course, the winding drive member 323 can be connected to the first winding roll 321 or the second winding roll 322 separately, or the first winding roll 321 and the second winding roll 322 can each be provided with a winding drive member 323, which is not limited here.

[0049] Specifically, the material receiving drive component 323 includes a material receiving motor 3231, a material receiving belt 3232, a material receiving drive wheel 3233 and a material receiving driven wheel 3234. The material receiving motor 3231 is connected to the material receiving drive wheel 3233. The material receiving driven wheel 3234 is connected to the material receiving drive wheel 3233 through the material receiving belt 3232. The material receiving driven wheel 3234 is connected to the first material receiving roll 321 and / or the second material receiving roll 322. By starting the material receiving motor 3231, the first material receiving roll 321 and / or the second material receiving roll 322 can be driven to rotate.

[0050] Furthermore, the stripping knife assembly 310 further includes a supporting roller 314 , which is rotatably connected to the separating stripping knife 311 , and the supporting roller 314 is located downstream of the separating stripping knife 311 .

[0051] With this arrangement, after the coil is peeled off by the separation peeling knife 311 , the movement of the film layer can be guided by contacting with the supporting roller 314 , thereby improving the conveying smoothness of the feeding device 10 .

[0052] In one embodiment, the material suction assembly 220 includes a material receiving platform 211 and a material receiving moving member 212 . The material receiving moving member 212 is respectively connected to the separation stripping knife 311 and the material receiving platform 211 , and the material receiving moving member is used to drive the material receiving platform 211 to approach or move away from the material suction assembly 220 .

[0053] In this embodiment, by setting a material-carrying movable part 212 connected to the material-carrying platform 211, the material-carrying movable part 212 can drive the material-carrying platform 211 to be close to or away from the material suction plate 221. In this way, when the material coil comes in an upside-down form, when the material suction plate 221 absorbs the material, the material-carrying platform 211 can be separated from the material suction plate 221 to avoid motion interference between the two and damage to the feeding device 10; after the material suction plate 221 absorbs the material, the material-carrying movable part 212 drives the material-carrying platform 211 to move in the opposite direction, so that the material-carrying platform 211 can absorb and move the material on the material suction plate 221 again, thereby realizing the material picking action of the material suction plate 221 and the material-carrying platform 211.

[0054] Specifically, the suction assembly 220 includes a suction plate 221, a suction air duct 222 and a suction movable member 223. The suction air duct is connected to the suction plate 221 and is used to connect to an external vacuum air source. The suction plate 221 is provided with an air hole connected to the suction air duct 222 and used to adsorb materials on the side facing the material receiving platform 211. The suction movable member 223 is respectively connected to the frame 100 and the suction plate 221. The material receiving movable member 212 is used to drive the material receiving platform 211 to approach or move away from the suction plate 221.

[0055] With this arrangement, the suction duct 222 can be used to connect to an external vacuum air source. When the suction plate 221 comes into contact with the material, the suction duct 222 is evacuated to create negative pressure in the air holes of the suction plate 221, thereby adsorbing and fixing the material. By setting a suction movable part 223 to drive the suction plate 221, the relative position between the suction plate 221 and the material receiving platform 211 can be adjusted, and by cooperating with the material receiving movable part 212, the operating flexibility of the carrying device 200 can be further improved.

[0056] Furthermore, the winding device 300 also includes a conveying assembly 330, which includes a conveying roller 331, an auxiliary roller 332 and a roller driving member 333. The conveying roller 331 and the auxiliary roller 332 are respectively rotatably connected to the frame 100 and are arranged in parallel to form a channel for conveying the film layer. The roller driving member 333 is used to drive the conveying roller 331 to rotate and drive the film layer to be conveyed toward the winding assembly 320.

[0057] When using the feeding device 10 of this embodiment, the film layer peeled off by the separation peeling knife 311 can contact the conveying roller 331 and the auxiliary roller 332. At this time, the conveying roller 331 is driven to rotate by the roller driving member 333 to drive the film layer to move toward the winding assembly 320 to improve the winding efficiency.

[0058] In one embodiment, the winding device 300 further includes a roller moving member 334 , which is respectively connected to the frame 100 and the auxiliary roller 332 , and is used to drive the auxiliary roller 332 to approach or move away from the conveying roller 331 .

[0059] According to this arrangement, the distance between the auxiliary roller 332 and the conveying roller 331 can be adjusted by starting the roller driving member 333 to compress or release the film layer. When compressing, the friction between the conveying roller 331 and the auxiliary roller 332 and the film layer can be increased, thereby improving the conveying stability of the film layer; when releasing, it can facilitate actions such as film unloading.

[0060] Specifically, the roller driving component 333 includes a roller motor 3331, a roller driving wheel 3332, a roller driven wheel 3333 and a roller belt 3334. The roller motor 3331 is connected to the roller driving wheel 3332. The roller driven wheel 3333 and the roller driving wheel 3332 are connected through the roller belt 3334. After the roller motor 3331 is started, the roller driven wheel 3333 can be driven through the roller belt 3334 to finally realize the function of driving the conveying roller 331. The use of belt drive can make the conveying component 330 compact in structure and low in maintenance cost.

[0061] In one embodiment, the roller driving member 333 also includes a roller tensioner 3335, which is adjustably connected to the frame 100, and the roller tensioner 3335 is crimped to one side of the roller belt 3334. The tension of the roller belt 3334 is adjusted by adjusting the relative position of the roller tensioner 3335 on the frame 100.

[0062] In one embodiment, the loading device 400 includes a loading roll 410 and a loading pressure wheel 420, and the loading roll 410 is used to carry the coiled material; the loading roll 410 and the loading pressure wheel 420 are both rotatably connected to the frame 100, the loading pressure wheel 420 is arranged downstream of the loading roll 410, and the loading pressure wheel 420 is used to press the side of the coiled material away from the loading roll 410.

[0063] With this arrangement, when the coil is output from the loading roll 410, it can roll in contact with the loading pressure wheel 420 and be guided by the loading pressure wheel 420 to improve the smoothness of the conveying of the coil.

[0064] Furthermore, the loading device 400 also includes a supporting assembly 430, the supporting assembly 430 includes a loading pallet 431 and a loading movable member 432, the loading movable member 432 is respectively connected to the frame 100 and the loading pallet 431, the loading pallet 431 is provided with an arc-shaped guide surface on the side facing the coil and is used to contact the coil, and the loading movable member 432 is used to drive the loading pallet 431 to move relative to the frame 100.

[0065] By arranging the loading moving member 432 to cooperate with the loading supporting plate 431, the relative position between the loading supporting plate 431 and the loading roll 410 can be adjusted to increase the tension of the roll when it is output to prevent the roll from loosening.

[0066] In one embodiment, the feeding device 400 further includes a feeding belt 440 , and the feeding belt 440 is connected to the feeding roll 410 and the winding assembly 320 , respectively.

[0067] With this arrangement, when the loading roll 410 rotates, the winding assembly 320 can be driven to rotate together to realize the winding function, and the transmission structure is simplified; Figure 4As shown, the feeding belt 440 can be connected to the feeding roll 410 and the second receiving roll 322 respectively.
