[0020] Preferred embodiment.

[0021] like Figure 1-3 As shown, the present invention discloses a paper bag forming device, comprising a support module 100, a cutting module 200 and an opening module 300, wherein the cutting module 200 and the opening module 300 are both installed on the support module 100, wherein:

[0022] The support module 100 includes a top plate 110, a first riser 120, and a second riser 130, wherein the first riser 120 and the second riser 130 are respectively installed on both sides of the top plate 110;

[0023] The cutting module 200 includes an upper knife unit 210 and a lower knife unit 220, wherein the upper knife unit 210 includes a first cylinder 211, a first slide rail 212, a second slide rail 213, a first slider 214, a second slider 215, a first driving plate 216 and a first blade 217, wherein the first cylinder 211 is mounted on the top plate 110, the first slide rail 212 is fixedly mounted on the first vertical plate 120 and the second slide rail 212 is fixedly mounted on the second vertical plate 130, the first slider 214 is mounted on the first slide rail 212 and the second slider 215 is mounted on the second slide rail 213, the first driving plate 216 is fixedly connected to the first slider 214 and the second slider 215 respectively and the first driving plate 216 is also connected to the driving end of the first cylinder 211, and the first blade 217 is fixedly mounted on the first driving plate 216; the lower knife unit 220 includes a blade mounting seat 221 and a second blade 222, and the second blade 222 is fixedly mounted on the blade mounting seat 221;

[0024] The opening module 300 includes an upper suction unit 310 and a lower suction unit 320. The upper suction unit 310 includes a second cylinder 311, a second driving plate 312 and a first suction plate 313. The second cylinder 311 is installed on the top plate 110 and the second driving plate 312 is connected to the driving end of the second cylinder 311. The first suction plate 313 is installed on the side of the second driving plate 312 away from the second cylinder 311 and the first suction plate 313 is provided with a first air pump connector 3131 and a plurality of first suction holes; the lower suction unit 320 includes a suction plate mounting base 321 and a second suction plate 322.
