[0030] The feeding mechanism 1 is provided with a conveying belt 15, a first motor 16 for driving the rotation of the conveying belt 15, and a translation and lifting assembly for driving the movement of the conveying belt 15. The conveying belt 15 is a sponge conveying belt. The rubber sheet is attached to the cylindrical mold 22 by the elasticity and friction of the sponge conveying belt. One of the conveying shafts in the conveying belt 15 is driven to rotate by the first motor 16 and the belt wheel set, so as to drive the conveying belt 15 to rotate for feeding. The translation and lifting assembly is used to drive the translation and lifting of the conveying belt 15, so as to lift the conveying belt 15 to a position close to the winding mechanism 2, so as to wind the rubber sheet. The movement of the conveying belt 15 is used to assist the winding of the rubber sheet, so as to ensure that the rubber sheet can be closely attached to the cylindrical mold 22.

[0031] The winding mechanism 2 comprises a hollow spindle 23 corresponding to the conveying belt 15, a cylindrical mold 22 sleeved outside the hollow spindle 23, a second motor 25 for driving the rotation of the hollow spindle 23, and an air inlet 26 rotationally connected to the hollow spindle 23. The other end of the air inlet 26 is connected to a gas supply device. A plurality of air guide holes 231 are formed through the hollow spindle 23. A plurality of air outlet holes 221 are uniformly formed on the surface of the cylindrical mold 22. The hollow spindle 23 and the cylindrical mold 22 are driven to rotate by the second motor 25 and the belt wheel set, so as to wind the rubber sheet. After the winding and forming, air is supplied to the hollow spindle 23 through the air inlet 26. The air is uniformly blown outwards through the air outlet holes 221, so that the rubber sheet is separated from the cylindrical mold 22, and the material is conveniently removed.

[0032] Based on the above technical scheme, when the diaphragm air spring is formed, the profile of the corresponding rubber sheet is marked on the conveying belt 15 by the infrared marking mechanism 3 according to the shape of the rubber sheet. The corresponding rubber sheet is placed in the specified marking line by manual operation. The conveying belt 15 drives the rubber sheet to move to the cylindrical mold 22. The conveying belt 15 is lifted to the cylindrical mold 22 by the translation and lifting assembly, so that one end of the rubber sheet is attached to the cylindrical mold 22. The cylindrical mold 22 is driven to rotate passively by the rotation of the conveying belt 15. When necessary, the second motor 25 can be started to assist the rotation of the cylindrical mold 22, so as to ensure that the rubber sheet can be closely attached to the surface of the cylindrical mold 22. After all the rubber sheets are attached, the diaphragm air spring is formed. Finally, air is supplied through the air inlet 26, and the air is uniformly blown outwards through the air outlet holes 221 to form an air layer, so that the diaphragm air spring is conveniently removed. The cylindrical mold 22 is driven to rotate passively by the feeding of the conveying belt 15. Compared with the traditional translation of the cylindrical mold 22 for winding, the feeding accuracy can be more accurately controlled, the flatness of the rubber sheet attachment can be improved, and the forming quality of the diaphragm air spring can be improved.

[0033] In the technical scheme, the infrared marking mechanism 3 is used to mark the profile of the corresponding rubber sheet on the conveying belt 15 according to the shape of the rubber sheet. The corresponding rubber sheet is placed in the specified marking line by manual operation. The conveying belt 15 drives the rubber sheet to move to the cylindrical mold 22. The conveying belt 15 is lifted to the cylindrical mold 22 by the translation and lifting assembly, so that one end of the rubber sheet is attached to the cylindrical mold 22. The cylindrical mold 22 is driven to rotate passively by the rotation of the conveying belt 15. When necessary, the second motor 25 can be started to assist the rotation of the cylindrical mold 22, so as to ensure that the rubber sheet can be closely attached to the surface of the cylindrical mold 22. After all the rubber sheets are attached, the diaphragm air spring is formed. Finally, air is supplied through the air inlet 26, and the air is uniformly blown outwards through the air outlet holes 221 to form an air layer, so that the diaphragm air spring is conveniently removed. The cylindrical mold 22 is driven to rotate passively by the feeding of the conveying belt 15.

The lifting cylinder 14 is used for lifting the conveyor belt 15 to press the rubber on the cylindrical mold 22, so as to stably attach the rubber on the cylindrical mold 22 and ensure the stable winding of the rubber.
