[0024] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0025] See also Figure 1-3A paper machine forming wire structure, comprising a frame 1, an elastic partition 2 is fixedly connected to the inner side of the frame 1, a partition 3 is connected between one side of the elastic partition 2 and the frame 1, a sealed cavity 4 is formed between the other side of the elastic partition 2 and the frame 1, a motor 5 is fixedly connected to one end of the sealed cavity 4, a longitudinal shaft 6 is fixedly connected to the rotor of the motor 5, and a first vibration mechanism, a second vibration mechanism and a third vibration mechanism are sequentially arranged on the longitudinal shaft 6;

[0026] The motor 5 is turned on, and the rotation of the motor 5 drives the longitudinal shaft 6 to rotate. The rotation of the longitudinal shaft 6 drives the first vibration mechanism, the second vibration mechanism and the third vibration mechanism to vibrate, so that the net of the paper machine can spread the pulp evenly and ensure the quality of the paper.

[0027] The first vibration mechanism includes a first bevel gear 7 and a second bevel gear 8 fixed to the outside of the longitudinal rotating shaft 6. The first bevel gear 7 and the second bevel gear 8 are both incomplete bevel gears. A bearing seat 9 is fixedly connected to the frame 1.

Two elastic connecting blocks 13 are fixedly connected to the elastic partition 2. The driving rotating rod 12 and the elastic connecting block 13 are staggered.

[0028] The first bevel gear 7 and the second bevel gear 8 in the first vibration mechanism are alternately reciprocated and meshed with the driven bevel gear 11 under the rotation drive of the longitudinal shaft 6, thereby causing the driving rod 12 fixedly connected to the driven bevel gear 11 to rotate. The rotation of the driving rod 12 can give the partition net 3 a vibration through the elastic connecting block 13.

[0029] A handle 14 is fixedly connected to the outer side of the frame 1 , and the handle 14 is fixedly connected to the frame 1 via bolts.

When the ratchet 20 rotates continuously, the ratchet teeth on the outer side will cooperate with the driven block 21 to generate vibration, thereby promoting the uniformity of the paper. The first vibration mechanism, the second vibration mechanism and the third vibration mechanism generate vibration in different ways, so the vibration effect can be better under the combined effect.

[0033] In one embodiment, the distance between the second vibration mechanism and the motor 5 is smaller than the distance between the first vibration mechanism and the motor 5 .

[0035] In one embodiment, the distance between the first vibration mechanism and the second vibration mechanism is equal to the distance between the second vibration mechanism and the third vibration mechanism.

[0036] In one embodiment, a spiral blade 22 is fixedly connected to the outer side of the longitudinal rotating shaft 6, and heat dissipation holes 23 are provided at both ends of the sealed cavity 4, and the spiral blade 22 is located on the side close to the motor 5.
