[0032] The rack 10 is provided with a collecting groove 101 for collecting the packaging bags 60, and the inner bottom surface of the collecting groove 101 is provided with a supporting seat 102 for supporting the packaging bags 60 so as to be taken out of the collecting groove 101 by hand. Specifically, the rack 10 has a base 11 and a support 12, the base 11 is provided with a platform 111, the front end of the platform 111 is provided with a front baffle 13 and two side baffles 14 which are arranged on the left and right sides, and the support 12 is arranged at the rear end of the platform 111, and the support 12, the front baffle 13 and the two side baffles 14 form the aforementioned collecting groove 101.

[0033] The first slow conveying device 20 and the second slow conveying device 30 are arranged on the rack 10 and arranged in parallel along the conveying direction of the packaging bags 60. In this embodiment, the first slow conveying device 20 and the second slow conveying device 30 are arranged on the support 12. The first slow conveying device 20 and the second slow conveying device 30 form a cutting gap 103. The first slow conveying device 20 is a wide belt conveying device, and the specific structure and working principle thereof are prior art, and the specific structure and working principle of the first slow conveying device 20 will not be described in detail here. The second slow conveying device 30 is also a wide belt conveying device, and the specific structure and working principle thereof are prior art, and the specific structure and working principle of the second slow conveying device 30 will not be described in detail here.

[0034] The cutting device 40 is arranged on the rack 10 and located between the first slow conveying device 20 and the second slow conveying device 30. In this embodiment, the cutting device 40 is arranged on the support 12. Specifically, the cutting device 40 includes a cutting seat 41, a cutting knife 42 and a driving cylinder 43, the cutting seat 41 is located directly below the cutting gap 103, the cutting knife 42 is located directly above the cutting gap 103 and cooperates with the cutting seat 41, and the driving cylinder 43 drives the cutting knife 42 to move up and down so as to separate or close the cutting knife 42 and the cutting seat 41. Moreover, the driving cylinder 43 is a pneumatic cylinder, which can cut more quickly.

[0035] The quick conveying device 50 is arranged on the frame 10 and located outside the output end of the second slow conveying device 30, and the quick conveying device 50 is located above the side of the collecting groove 101. In the embodiment, the quick conveying device 50 is arranged on the support 12. Specifically, the quick conveying device 50 comprises two conveying assemblies 51 which are symmetrically arranged above and below, and a conveying gap 501 for the packaging plastic bags 60 to pass through is formed between the two conveying assemblies 51. Each conveying assembly 51 comprises a driving roller 511, a driven roller 512 and a plurality of narrow belts 513. The driving roller 511 is driven to rotate by the motor 52. The driven roller 512 is located at the front side of the driving roller 511 and is arranged in parallel with the driving roller 511 at an interval. The plurality of narrow belts 513 are connected between the driving roller 511 and the driven roller 512 and are arranged at an interval along the axial direction of the driving roller 511 and the driven roller 512.

[0036] The working principle of the embodiment is described as follows:

[0037] The packaging plastic bags 60 to be cut are conveyed forward under the action of the first slow conveying device 20. When a packaging plastic bag 60 is output from the first slow conveying device 20 and enters the second slow conveying device 30, the cutting device 40 works to cut off a complete packaging plastic bag 60. Then, the cut packaging plastic bag 60 enters the quick conveying device 50 under the action of the second slow conveying device 30. Under the action of the quick conveying device 50, the packaging plastic bag 60 flies out and enters the collecting groove 101. In this way, the packaging plastic bags 60 continuously fly out one by one and are stacked in the collecting groove 101. When the packaging plastic bags 60 are stacked to a certain thickness, the operator can put his hand into the collecting groove 101 and close to the side of the supporting seat 102, and a plurality of packaging plastic bags 60 stacked together can be quickly grabbed out.

[0038] The design emphasis of the utility model lies in that: the cutting device is arranged between the first slow conveying device and the second slow conveying device, so that the packaging plastic bags are cut during slow conveying. Then, the cut packaging plastic bags are quickly flown out and fall into the collecting groove for stacking by the quick conveying device. Meanwhile, the supporting seat is arranged in the collecting groove, so that the packaging plastic bags stacked together can be taken out of the collecting groove by hand. In this way, the packaging plastic bags do not need to be stacked one by one by manual work, the production efficiency is greatly improved, the labor cost is reduced, and the enterprise production operation is facilitated.

[0039] The above merely describes the preferred embodiment of the present application, and is not intended to limit the technical scope of the present application in any way. Any slight modification, equivalent change, and modification made according to the technical essence of the present application shall still fall within the scope of the technical scheme of the present application.
