[0019] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0020] See also Figure 1-Figure 3 The utility model provides a technical solution: an air filter screen forming machine includes a support platform 12, and guide rods 3 are fixedly connected to the four corners of the upper end surface of the support platform 12. A top plate 2 is fixedly installed on the top of the guide rod 3. An electric telescopic rod 1 is fixedly installed at the middle position of the upper end surface of the top plate 2.

[0021] A mounting plate 4 is slidably arranged on the four guide rods 3 .

[0022] Specifically, sliding holes are provided at positions on the mounting plate 4 corresponding to the guide rods 3. The guide rods 3 are correspondingly slidably inserted in the sliding holes.

[0023] The upper end surface of the mounting plate 4 is fixedly connected to the telescopic end of the electric telescopic rod 1. The lower end surface of the mounting plate 4 is fixedly connected with an upper mold 5.

[0024] The side wall of the support platform 12 is fixedly connected with the material discharging platform 11. The upper end surface of the support platform 12 is fixedly mounted with a fixing plate 10.

[0025] The upper end surface of the fixed plate 10 is rotatably provided with a rotating shaft 8. The outer side of the rotating shaft 8 is fixedly connected with the lower mold 7. The lower end surface of the lower mold 7 is provided with a molding groove 13. The molding groove 13 is correspondingly provided with the discharge platform 11 and the upper mold 5.

[0026] Specifically, a sleeve is fixedly mounted on the upper end surface of the fixed plate 10 corresponding to the side of the material discharging platform 11. The rotating shaft 8 is rotatably mounted inside the sleeve. Both ends of the rotating shaft 8 extend to the outside of the sleeve. Two protrusions are integrally formed on one side of the lower mold 7 corresponding to the rotating shaft 8. The two protrusions are fixedly connected to the two ends of the rotating shaft 8 respectively.

[0027] A gear 9 is fixedly connected to one end of the rotating shaft 8. A rack 6 is fixedly connected to the lower end surface of the mounting plate 4. The rack 6 is meshed with the gear 9. The rack 6 is staggered with the support platform 12 and the material discharge platform 11 so that the rack 6 does not contact the support platform 12 and the material discharge platform 11 when moving downward. The teeth on the rack 6 are partially set. When the toothed part on the rack 6 completely passes the gear 9, the gear 9 can be rotated 180°.

[0028] Working principle:

[0029] When in use, first start the electric telescopic rod 1, the electric telescopic rod 1 pushes the mounting plate 4 to fall, the mounting plate 4 slides on the guide rod 3, and the mounting plate 4 falls vertically. The mounting plate 4 drives the upper mold 5 and the rack 6 to move downward, and the rack 6 drives the meshing gear 9 to rotate. The gear 9 rotates through the rotating shaft 8 to drive the lower mold 7 to rotate around the axis of the rotating shaft 8. When the toothed part of the rack 6 passes through the gear 9, the position of the mounting plate 4 does not affect the rotation of the lower mold 7. The gear 9 drives the lower mold 7 to rotate 180 degrees around the axis of the rotating shaft 8, and the lower mold 7 rotates to the fixed plate 10 so that the molding groove 13 faces upward. The electric telescopic rod 1 stops extending, and the raw material is injected into the molding groove 13 on the lower mold 7. The electric telescopic rod 1 is started again to extend, and the electric telescopic rod 1 pushes the upper mold 5 and the rack 6 to continue to move downward through the mounting plate 4. Since the teeth on the rack 6 are partially set; at this time, the rack 6 is not meshed with the gear 9; until the upper mold 5 and the lower mold 7 are completely overlapped, the air filter is pressed.

[0030] After the pressing of the air filter is completed, the electric telescopic rod 1 is started to retract, and the electric telescopic rod 1 drives the upper mold 5 and the rack 6 to move upward, and the lower mold 7 remains stationary. When the toothed part of the rack 6 contacts the gear 9, the rack 6 drives the gear 9 to rotate, and the gear 9 drives the lower mold 7 to rotate. When the electric telescopic rod 1 is reset, the rack 6 drives the gear 9 and the lower mold 7 to rotate 180 degrees, and the finished product in the lower mold 7 falls on the discharge table 11 for cooling.

[0031] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
