Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] See also Figure 1 - Figure 3 The utility model provides a technical solution: a device for preventing a sheet protective film from being scratched, comprising a conveying platform 100, a lifting stacking platform 101 is arranged on the left side of the conveying platform 100, an electric lifting column 103 is arranged at the bottom of the lifting stacking platform 101, and a blowing stacking mechanism 200 is arranged between the lifting stacking platform 101 and the conveying platform 100. By setting up the blowing stacking mechanism 200, the falling sheet body 102 can be blown toward the lifting stacking platform 101 by wind force, and the blowing stacking mechanism 200 can be used to blow the falling sheet body 102 to the lifting stacking platform 101 for stacking. The plate body 102 is positioned so that the plate body 102 will not deviate, and the cut edge of the plate body 102 will not directly contact the surface of the plate body 102 below, thereby preventing damage to the protective film and increasing the safety and stability of the plate body 102 stacking. The blowing stacking mechanism 200 includes a blowing component 201 on the top of the blowing conveying platform 100 for placing the plate body 102, and the upper surface of the lifting stacking platform 101 is symmetrically provided with positioning components 202 on the front and rear surfaces of the plate body 102 for stacking;

[0023] The blowing member 201 includes an air duct 2012 longitudinally distributed at the left end of the conveying platform 100, a high-pressure fan 2011 is arranged at the lower end of the air duct 2012, and the weight of the plate body 102 is within the range of the wind energy discharged from the air duct 2012;

[0024] The positioning member 202 includes a positioning plate 2021 which is vertically fixed on the upper surface of the lifting stacking platform 101 and is respectively located on the front and rear surfaces of the sheet body 102. The positioning plate 2021 can position the stacked sheet body 102 front and back to facilitate the stacking of the sheet body 102. A plurality of ball bearings 2022 are arranged on the inner surface of the positioning plate 2021, and the ball bearings 2022 can reduce the friction resistance between the plate body 102 and the sheet body 102.

[0025] In this embodiment, preferably, the blowing component 201 also includes a connecting pipe 2015 installed between the air duct 2012 and the high-pressure fan 2011. The surface of the air duct 2012 is provided with a plurality of air outlet holes 2013 along its length direction. The air outlet holes 2013 are slightly offset to the left. The gas blown out from the air outlet holes 2013 acts on the lower surface of the plate body 102, giving the plate body 102 a wind force in the upper left direction, blowing the plate body 102 to float to the left. A bottom plate for supporting the high-pressure fan 2011 is horizontally arranged at the bottom of the conveying platform 100, and a support plate 2014 is arranged between the air duct 2012 and the bottom plate.

[0026] In this embodiment, preferably, the positioning member 202 also includes a driving cylinder 2026 vertically installed on the outer surface of the positioning plate 2021. The surface of the positioning plate 2021 is provided with a rectangular hole 2023 along its height direction for placing the filling plate 2024, so that the filling plate 2024 can move in the rectangular hole 2023 to change its height position.

[0027] In this embodiment, preferably, a filling layer 2025 is provided on the upper surface of the inner end of the filling plate 2024. The filling layer 2025 can be a cotton layer, which will not cause damage to the surface of the plate body 102. The lower end of the piston rod inside the rectangular hole 2023 is connected to the outer end of the filling plate 2024, which can drive the filling plate 2024 to move and change the height of the filling plate 2024, so that the filling plate 2024 can be re-positioned on the upper surface of the plate body 102.

[0028] In summary, the conveyor platform 100 conveys the sheet body 102 toward the lifting and stacking platform 101, and when the left end of the sheet body 102 is located between the two positioning plates 2021, and due to the wind force discharged from the inclined surface of the air duct 2012, the fallen sheet body 102 has a blowing force, so that the sheet body 102 is blown up and moves to the left and falls on the two filling plates 2024, so that the cut edge will not directly contact the stacked surface of the sheet body 102. When the fallen sheet body 102 is horizontally located on the surface of the sheet body 102 below, the positioning plate 2021 rotates outward to rotate the filling plate 2024 to separate from the sheet body 102, and the upper sheet body 102 moves downward to contact the lower sheet body 102, and the positioning plate 2021 and the side plate 204 are used to prevent the sheet body 102 from deviating, and the driving cylinder 2026 drives the filling plate 2024 to move upward a certain distance to facilitate re-positioning on the upper surface of the sheet body 102. The whole process increases the safety and stability of sheet body 102 unloading and stacking, and reduces the scrap rate.

[0029] Example 2

[0030] Reference Figure 4 , which is the second embodiment of the utility model, and this embodiment is different from the previous embodiment.

[0031] In this embodiment, preferably, the blowing stacking mechanism 200 also includes a positioning support member 203 that drives the two positioning members 202 to rotate back and forth. The positioning support member 203 can be used to change the position between the two positioning plates 2021, so that the plate body 102 can be positioned when it is stacked, and the positioning plate 2021 can be conveniently rotated outward, so that the filling plate 2024 can be separated from the plate body 102, and the filling plate 2024 can be conveniently re-positioned on the upper surface of the stacked plate body 102 to block the support. The positioning support member 203 includes a connecting plate 2031 fixed to the outer surface of the positioning plate 2021, and a mounting shaft 2032 is vertically arranged at the left end of the connecting plate 2031 to support the connecting plate 2031. At the same time, as the mounting shaft 2032 rotates, the connecting plate 2031 can be driven to rotate. The lower end of the mounting shaft 2032 is rotatably mounted on the upper surface of the lifting stacking platform 101, and a worm wheel 2033 is sleeved on the mounting shaft 2032. A worm 2034 is meshed on the outer side of the worm wheel 2033. The two worms 2034 distributed in the front and rear directions are meshed in opposite directions to the worm wheel 2033. A driving motor 2035 is arranged at the front end of the worm 2034. The driving motor 2035 can realize the in-situ rotation of the worm 2034. The blowing stacking mechanism 200 also includes a side plate 204 fixed on the upper surface of the lifting stacking platform 101 and located on the left side of the plate body 102. The side plate 204 plays a further positioning role in the stacking of the plate body 102, which facilitates stacking. The outer side of the side plate 204 is provided with a stabilizing plate 2036 for the middle support of the worm 2034, which plays a stabilizing support role for the worm 2034.

[0032] In summary, when the sheet bodies 102 are stacked downward, two filling plates 2024 are used to support the falling sheet bodies 102, so that the sheet bodies 102 are spaced apart from the sheet bodies 102 below, so that the left end of the upper sheet body 102 is not easy to contact the lower sheet body 102. When the upper sheet body 102 falls horizontally on the filling plates 2024 under the action of wind, the driving motor 2035 works, driving the worm 2034 to rotate, and the worm wheel 2033 meshing with it rotates, driving the two worm wheels 2033 to rotate in the opposite direction because the teeth of the two worms 2034 are distributed in opposite directions, driving the two mounting shafts 2032 and the connecting plate 2031 to rotate in the opposite direction. The upper plate 102 is allowed to fall downward onto the lower plate 102, and the distance between the two will not cause damage when falling, which is convenient for stacking the plate bodies 102. After the stacking is completed, the driving motor 2035 works again to allow the connecting plate 2031 and the positioning plate 2021 to rotate relative to each other and reset. In this process, the piston rod inside the driving cylinder 2026 drives the filling plate 2024 to move upward by a distance of the thickness of the plate body 102, so that the filling plate 2024 is convenient for being re-positioned on the upper surface of the plate body 102 to play a blocking and protective role.
