Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4 , a plastic woven bag flattening device, including a pressing component for elastically pressing and attaching to tension the plastic woven bag, and further including a box body component for pulling the plastic woven bag to move vertically and flatten it. A brush roller assembly for simultaneously brushing the plastic woven bag from both sides for cleaning is arranged in the middle of the box body component. There are two pressing components, which are evenly distributed up and down on one side of the box body component.

[0024] In this embodiment: The box body component includes a machine box body 101, and the machine box body 101 is made of 204 stainless steel material. A feeding port 102 is arranged on one side of the machine box body 101, a support roller 103 is arranged inside the machine box body 101, a driving roller 104 is arranged above the support roller 103, and a first motor 105 is arranged in front of the driving roller 104. The support roller 103 and the driving roller 104 are respectively connected to the machine box body 101 by bearings. The plastic woven bag enters from the feeding port 102 at the bottom of the machine box body 101 and is pulled out from the top of the machine box body 101. The first motor 105 drives the driving roller 104 to rotate to pull the plastic woven bag vertically upward from the upper end, and the support roller 103 cooperates with the pressing roller 301 to pull and flatten the lower end of the plastic woven bag;

[0025] In this embodiment: The pressing assembly includes a pressing roller 301. Two limiting edges 302 are symmetrically arranged at both ends of the pressing roller 301. Two sliders 303 are symmetrically installed at both ends of the pressing roller 301. A slide bar 304 is arranged on one side of the slider 303. A pressing spring 305 is installed on the slide bar 304. The pressing roller 301 is connected to the slider 303 by bearings. The slider 303 and the slide bar 304 are respectively slidably connected to the machine box body 101. The pressing spring 305 pushes the slider 303 to drive the pressing roller 301 to move under the support of the slide bar 304, and presses the plastic woven bag on the driving roller 104 and the supporting roller 103 at the upper and lower ends respectively.

[0026] In this embodiment: The brush roller assembly includes two transmission shafts 203 that are horizontally symmetrically arranged. A brush roller 201 is installed on the transmission shaft 203. The brush roller 201 is made of conductive rubber material. The brush roller 201 and the transmission shaft 203 are riveted together. A synchronous gear set 202 is arranged at one end of the transmission shaft 203. The synchronous gear set 202 is respectively connected to the two transmission shafts 203 by flat keys. A second motor 204 is arranged at one end of one of the transmission shafts 203 away from the synchronous gear set 202.

[0027] Working principle: The plastic woven bag enters from the feed port 102 at the bottom of the machine box body 101 and is pulled out from the top of the machine box body 101. During this process, the machine box body 101 supports the pressing spring 305 to push the slider 303 to drive the pressing roller 301 to move under the support of the slide bar 304, and presses the plastic woven bag on the driving roller 104 and the supporting roller 103 at the upper and lower ends respectively. The first motor 105 drives the driving roller 104 to rotate to pull the plastic woven bag to move vertically upward from the upper end. The supporting roller 103 cooperates with the pressing roller 301 to pull and flatten the lower end of the plastic woven bag. At the same time, the second motor 204 rotates through one transmission shaft 203 and drives the other transmission shaft 203 to rotate synchronously and reversely through the synchronous gear set 202, so that the brush rollers 201 on the two transmission shafts 203 rotate synchronously and reversely, and the plastic woven bag is cleaned by rolling brushes simultaneously from both sides.
