DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Example 1

[0020] Reference Figure 1-3 A cardboard double-sided shaping and drying machine comprises a support plate 1, both sides of the support plate 1 are fixedly connected with side plates 15, a fixing ear is fixedly connected to the support plate 1, a connecting frame 8 is arranged on the fixing ear through an intermittent lifting mechanism, an upper plate 14 is connected to the connecting frame 8 through a connecting mechanism, a plurality of heating resistors 4 are fixedly connected at equal distances on the relative outer sides of the upper plate 14 and the support plate 1, a pushing mechanism is arranged on the support plate 1, the heating resistor 4 is used to heat the support plate 1 and the upper plate 14, so that both sides of the cardboard can be dried at the same time, which is conducive to accelerating the drying efficiency, and at the same time, when drying, the two sides of the cardboard are abutted to prevent the cardboard from warping and deformation, shaping the cardboard, and ensuring the quality of the cardboard.

[0021] The intermittent lifting mechanism includes a motor 6, which is a low-speed motor installed on a fixed ear. An incomplete gear 5 is fixedly connected to the output shaft of the motor 6. A gear 10 is meshed on the incomplete gear 5. A threaded sleeve 20 is fixedly connected to the gear 10. The threaded sleeve 20 is rotatably connected to the fixed ear through a bearing. A reciprocating threaded rod 9 is threadedly connected to the threaded sleeve 20. A connecting frame 8 is fixedly connected to the reciprocating threaded rod 9. The connecting frame 8 is limited by a limiting mechanism and rotated by the motor 6 to drive the incomplete gear 5 to rotate, so that the gear 10 rotates intermittently, and the reciprocating threaded rod 9 rotates. The incomplete gear 5 meshes with the gear 10 to disengage, and the reciprocating threaded rod 9 performs a reciprocating rotation so that the upper plate 14 makes a reciprocating movement. When it disengages from the cardboard, it is beneficial to discharge the steam generated during the drying process. When the incomplete gear 5 meshes with the gear 10, the upper plate 14 will abut against the cardboard for drying.

[0022] The limiting mechanism comprises a column 7, which passes through a connecting frame 8 and is fixedly connected to a fixing ear. The limiting mechanism prevents the connecting frame 8 from rotating.

[0023] Example 2

By adopting the design of the abutting block 19, the restoring force of the spring 16 is used to abut the abutting block 19 against the gear 10, thereby preventing the gear 10 from rotating when the incomplete gear 5 is disengaged from the gear 10, so that the gear 10 can be re-engaged during the next rotation.

[0025] Example 3

[0026] Due to the different thickness of the paperboard, the distance between the upper plate 14 and the supporting plate 1 is different.

When the telescopic rod 2 is contracted, the pushing plate 3 is driven to move, and the cardboard is pushed, so that one end of the cardboard is moved out of the support plate 1, and the cardboard is removed.

[0029] In use, by placing the cardboard on the support plate 1, starting the motor 6 to drive the incomplete gear 5 to rotate, so that the gear 10 rotates intermittently, and the reciprocating threaded rod 9 rotates, and the incomplete gear 5 goes from being engaged with the gear 10 to being disengaged, and the reciprocating threaded rod 9 makes a reciprocating rotation, which will drive the upper plate 14 to move back and forth.
