[0018] Refer to the attached Figure 1-4 , an EVA rubber sheet suspension conveying platform, which includes a pendulum conveying platform 1 and a blowing part 2. The pendulum conveying platform 1 includes a conveying table 11, a pendulum part 12 and a box 13. The conveying table 11 is installed on the upper end of the box 13. A plurality of pendulum parts 12 are installed in the box 13. The upper ends of the pendulums of the plurality of pendulum parts 12 extend from the conveying table 11 to a certain height. Each pendulum is surrounded by through holes 4 on the conveying table 11. The blowing part 2 includes a plurality of upper transverse air pipes 21. The plurality of upper transverse air pipes 21 are respectively installed under the conveying table 11. The upper end of each air pipe is respectively provided with a plurality of blowing holes 211. The plurality of blowing holes 211 are respectively located below the through holes 4. The pendulum of the pendulum part is an electric roller, which belongs to the prior art. For example, it is described in patent CN202321218126.7. The present invention is briefly introduced.

[0019] A plurality of blowing holes 211 are correspondingly opened on the upper transverse air pipe 21 below each through hole 4, and the plurality of blowing holes 211 are sequentially arranged forward along the upper transverse air pipe 21. The plurality of blowing holes 211 form an airflow inclined forward. One of the plurality of blowing holes can blow upward, and the others can be sequentially inclined forward at a certain angle to ensure that the airflow forms a force to blow forward, ensure that the EVA rubber sheet is partially blown up, and give the EVA rubber sheet a forward force.

[0020] A blower mechanism 3 is also provided above the conveying table 11. The blower mechanism 3 includes a bellows 31 and a support arm 32. A round tube is respectively installed on the rear sides of both ends of the bellows 31. The round tube is connected to the upper end of a support arm 32 with damped rotation. The lower end of the support arm 32 is installed on the box body 13 with damped rotation. A strip-shaped blowing port 33 is provided on the front side of the bellows 31. The damped rotation design can ensure that the direction of the blowing port can be adjusted, and also ensure that there will be no rotation after adjustment. In the view given in the present invention, the lower end of the support arm is installed under a horizontal frame with damped rotation, and the two sides of the horizontal frame are installed on the ground through a frame. The installation position of the lower end of the support arm is not a technical problem to be solved by the present invention, but belongs to the prior art, and the present invention is briefly described.

[0021] The bellows 31 comprises a rectangular shell and a triangular ribbed shell, the rear end of the triangular ribbed shell is connected and communicated with the front end of the rectangular shell, the two sides of the rectangular shell are respectively connected to the support arm 32 through a circular tube damping, and a strip blowing port 33 is opened at the front end of the triangular ribbed shell.

[0022] The blowing part 2 also includes a plurality of longitudinal air pipes 22, a plurality of vertical air pipes 23 and a plurality of lower transverse air pipes 24. Two longitudinal air pipes 22 and two lower transverse air pipes 24 are connected end to end to form a rectangular pipe. The remaining longitudinal air pipes 22 and lower transverse air pipes 24 are connected and installed inside the rectangular pipe as needed, and the longitudinal air pipes 22 and the lower transverse air pipes 24 are connected and connected at the intersection position; the lower ends of the plurality of vertical air pipes 23 are respectively connected and installed vertically on the plurality of longitudinal air pipes 22 and the plurality of lower transverse air pipes 24, and the upper ends of the plurality of vertical air pipes 23 are respectively connected and installed vertically on the plurality of upper transverse air pipes 21; the plurality of longitudinal air pipes 22 and / or the plurality of lower transverse air pipes 24 are fixed at the bottom of the box body 13 of the swing wheel conveying platform 1, and the plurality of longitudinal air pipes 22 and / or the plurality of lower transverse air pipes 24 are connected to the external air intake pipe.

[0023] The strip-shaped air outlet of the blower mechanism 3 is tilted forward toward the upper position of the pendulum wheel of the wheel section. The blower mechanism is mainly designed to cooperate with the blowing part below to act on the EVA rubber sheet. The blowing part blows the EVA rubber sheet from below to form a suspended state, and the EVA rubber sheet will not rub against the conveying table. However, in order to ensure that the EVA rubber sheet is also in contact with the pendulum wheel, the upper blowing mechanism directly blows air to the upper part of the wheel to press down the EVA rubber sheet. In this way, the EVA rubber sheet can be effectively and smoothly conveyed forward. In this way, the pendulum wheel section can also accurately control the conveying direction of the EVA rubber sheet when changing direction, and the unloading position is accurate, so that the EVA rubber sheet can be stacked in an orderly manner.

[0024] The upper transverse air pipes 21, the longitudinal air pipes 22, the vertical air pipes 23 and the lower transverse air pipes 24 of the blowing part 2 are respectively located in the gaps between the balance parts 12. This design is mainly to prevent the air pipes from interfering with the balance part, ensuring that the swing reversing action of the balance part is not affected.

[0025] When the present invention is in use, air holes for blowing obliquely forward are designed on the conveying table, and the air holes are located around the balance wheel of the balance wheel part. In this way, the places where the EVA rubber sheet is not in contact with the balance wheel can be blown up by the airflow, and the EVA rubber sheet is in a suspended state. The relative friction contact between the EVA rubber sheet and the balance wheel is retained, so that the friction force between the EVA rubber sheet and the conveying table is almost zero, and the transmission of the EVA rubber sheet to the balance wheel will not be affected. The present invention also has a blower mechanism, and the blower mechanism can adjust the blowing angle of the EVA rubber sheet to ensure that the EVA rubber sheet is effectively contacted and driven with the plurality of balance wheels below.
