[0014] In order to make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the following further details the present utility model in conjunction with the attached drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0015] Refer to Figure 1-Figure 3 A linkage - type automatic film feeding and cutting device shown, which includes a material channel 1 and a side plate 2. A feeding cam 3 is rotatably connected to the middle of the material channel 1. A guillotine knife 4 is arranged at the end of the material channel 1. A driving assembly is arranged on the side plate 2. The driving assembly includes a servo motor 501 and a gear set 502. One output end of the gear set 502 is fixedly connected to the feeding cam 3. The other output end of the gear set 502 is fixedly connected to a swing arm 6. The servo motor 501 is used to drive the gear set 502 to transmit power. On the one hand, the gear set 502 can drive the feeding cam 3 to swing for feeding. The lower end of the guillotine knife 4 is hinged to the material channel 1. The upper end of the guillotine knife 4 is hinged to a C - shaped seat 7. A guide rod 701 is fixedly connected to the C - shaped seat 7.
