[0039] The present invention will be further described in detail below through specific implementation examples in conjunction with the accompanying drawings.

[0040] See also Figure 1-Figure 5The present embodiment provides a flyer device, which includes a material discharging mechanism 100, a material receiving mechanism 200, a gravity roller assembly, a stripping knife 410, a label receiving platform 500 and a driving mechanism 600; the material discharging mechanism 100 is used to carry the coiled material and send the material discharging belt 900, the material receiving mechanism 200 is used to collect the coiled material waste, the gravity roller assembly and the stripping knife 410 are both arranged between the material discharging mechanism 100 and the material receiving mechanism 200; the gravity roller assembly includes a first guide structure 310 and a gravity roller 320, the first guide structure 310 and the gravity roller 320 are connected to each other. 20 cooperates to guide the gravity roller 320 to move vertically, and the material belt 900 can bypass the gravity roller 320 from below; the label receiving platform 500 is arranged close to the stripping knife 410 and there is a material passing gap between it and the stripping knife 410, and the end of the driving mechanism 600 is connected to the label receiving platform 500, which is used to drive the label receiving platform 500 to open or close; the width of the material passing gap when the label receiving platform 500 is in the open state is greater than the width when the label receiving platform 500 is in the closed state. In the closed state, the label receiving platform 500 can receive the label peeled off by the stripping knife 410.

[0041] When the coiled material is installed for the first time or when the material needs to be changed, the coiled material is first installed on the unloading mechanism 100, and then the head section of the coiled material is pulled out, and the material strip 900 is led around the gravity roller 320 to the material gap between the stripping knife 410 and the label receiving platform 500, and the driving mechanism 600 is used to drive the label receiving platform 500 to open, so as to increase the width of the material gap, so that the material strip 900 led to the material gap can easily pass through the enlarged material gap, and after the material strip 900 passes through the material gap, it can be led to the receiving mechanism 200. In this way, the difficulty of the material strip 900 passing through the material gap can be greatly reduced, and the efficiency of the first installation of the coiled material or the material changing efficiency is improved; after the installation is completed, the driving mechanism 600 can be used to drive the label receiving platform 500 to close, so that the label receiving platform 500 is restored to its original closed state, so as to reduce the width of the material gap, so that the label peeled by the stripping knife 410 can fall smoothly to the label receiving platform 500, and prevent the label from falling.

[0042] After the installation work is completed, the material belt 900 can be fed and unfurled by the unfeeding mechanism 100, and the waste coiled materials that have been stripped of the labels can be collected by the collecting mechanism 200. When the suspended material belt between the unfeeding mechanism 100 and the collecting mechanism 200 becomes shorter, the gravity roller 320 can adaptively move upward under the lifting force of the material belt 900 to shorten the length of the material feeding path, so that the shortened material belt 900 maintains appropriate tension, which can prevent the material belt 900 from being torn apart due to excessive tension; when the suspended material belt between the unfeeding mechanism 100 and the collecting mechanism 200 becomes longer, the gravity roller 320 can adaptively move downward under the action of its own gravity to lengthen the length of the material feeding path, so that the lengthened suspended material belt remains taut, so as to prevent the suspended material belt from being too long and loose. In other words, the setting of the gravity roller assembly can keep the tension of the material belt 900 within an appropriate range, which is beneficial to improving the smoothness of material feeding.

During the label stripping process, the detection device 330 may monitor the position of the gravity roller 320 in real time. Once the gravity roller 320 moves upward to the upper limit position, the detection device 330 will send a material discharging start signal to the material discharging mechanism 100. After receiving the material discharging start signal from the detection device 330, the material discharging mechanism 100 may automatically start discharging to ensure the supply of raw materials. Once the gravity roller 320 moves downward to the lower limit position, the detection device 330 will send a material discharging stop signal to the material discharging mechanism 100. After receiving the material discharging stop signal from the detection device 330, the material discharging mechanism 100 may automatically stop discharging to prevent the suspended material belt from being too long and loose. In this way, the tension adjustment function of the gravity roller 320 on the suspended material belt can be maintained to ensure the smoothness of the material feeding, and there is no need for manual monitoring and adjustment of feeding and receiving, and the degree of automation is high.

[0045] The above-mentioned detection device 330 may specifically include an upper limit sensor 331 and a lower limit sensor 332. The upper limit sensor 331 may be set to be triggered by the gravity roller 320 in the upper limit position. In this way, when the gravity roller 320 rises to the upper limit position, the upper limit sensor 331 can be triggered and can send a start discharge signal to the discharge mechanism 100; the lower limit sensor 332 may be set to be triggered by the gravity roller 320 in the lower limit position. In this way, when the gravity roller 320 drops to the lower limit position, the lower limit sensor 332 can be triggered and can send a stop discharge signal to the discharge mechanism 100.

During installation, the coiled material can be put on the unloading roller; the unloading motor is connected to the unloading roller, and the unloading motor is used to drive the unloading roller to rotate.
