[0019] The present invention will be further described in detail below through specific embodiments. The following embodiments are only descriptive and not restrictive, and the protection scope of the present invention cannot be limited by them.

[0020] like Figure 1 The aluminum foil conveying device shown comprises: a support frame 6 and a motor 5, a reducer 4, and a rotating shaft 2 connected in sequence, wherein the input end of the reducer 4 is connected to the motor 5; the rotating shaft 2 has a first end and a second end, and the first end of the rotating shaft 2 is connected to the output end of the reducer 4. Two rotating shaft support members 3 are fixedly installed in parallel and spaced apart on the top of the support frame 6, and the two rotating shaft support members 3 are used to support the rotating shaft 2. Two limiting grooves are formed at both ends of the rotating shaft 2, and are rotatably matched with the rotating shaft support members 3. As a preferred embodiment, the rotating shaft support member 3 comprises two bearings and a bearing seat, and the two bearings are installed on the bearing seat in a mirror-symmetrical manner.

[0021] In order to realize linkage with the paper cutter of the material feeding mechanism, a linkage mechanism and a position sensor 7 are also included. The linkage mechanism is hingedly mounted on the middle of the front side of the support frame 6; the position sensor 7 is fixedly mounted on the support frame 6, including an upper position sensor and a lower position sensor; the linkage mechanism and the position sensor 7 cooperate to control the start and stop of the motor 5.

[0022] As a preferred embodiment, the linkage mechanism includes a linkage rod 8-1 and two connecting arms 8-2, two connecting walls are fixed at both ends of the linkage rod 8-1, the connecting arm 8-2 has a first end and a second end, the first end of the connecting arm 8-2 is fixed to the linkage rod 8-1, and the second end of the connecting arm 8-2 is hinged to the support frame 6 through an axis.

[0023] As a preferred implementation, the position sensor 7 is a proximity switch or a contact switch.

[0024] In order to protect the aluminum foil bypassing the linkage rod 8 - 1 , two baffles 9 are also included, which are symmetrically installed on both sides of the linkage mechanism.

[0025] In order to protect the rotating shaft support member 3, a rotating shaft support member 3 protection cover is also included, which is respectively covered on the two rotating shaft support members 3.

[0026] The method of using this device is:

[0027] This device is used for conveying aluminum foil 1, and is used in conjunction with a paper cutter. A linkage rod 8-1 is set at the front end. When the paper cutter drives the aluminum foil forward, the linkage rod 8-1 is lifted, triggering the upper position sensor, and the signal is fed back to the motor 5. The motor 5 starts and runs at the set frequency, and the aluminum foil begins to be conveyed. After a period of time, if the aluminum foil is retained, the linkage rod 8-1 drops, triggering the lower position sensor, and the signal is fed back to the motor 5, and the motor 5 stops running. The front end paper cutter is repeatedly operated in this way to ensure that the aluminum foil is smoothly conveyed according to the use. When changing the roll, the rotating shaft 2 is lifted and the paper barrel is inserted from one side.
