The number of the bidirectional screw rods 300 is four, which are rotatably installed on the surfaces of the vertical rods 110 respectively. The inner sides of each first roller seat 120 and second roller seat 130 are rotatably installed with threaded sleeve 150, and the surfaces of the first roller seat 120 and second roller seat 130 are provided with clutch pin rods 160.

The surface of the straight toothed rod 220 is provided with a screw groove ring tooth edge 221 meshing with the surface of the transmission tooth 310. In this embodiment, the straight toothed rods 220 are symmetrically arranged at both ends of the piston cylinder 211, the output end of the hydraulic pump station 210 is in communication with the middle section of the inner cavity of the piston cylinder 211, and the communication point between the two straight toothed rod 220 end pistons is used to drive the synchronous linear motion of the two straight toothed rods 220.

[0030] Working effect description:

[0031] The embodiment ensures the parallel movement of the first roller seat 120 and the second roller seat 130 along the correct trajectory during the adjustment process by the straight-toothed rod 220 piston in the hydraulic drive assembly 200 to exert synchronous linear motion on the four bidirectional screw rods 300.

The difference is that the engagement mode between the clutch pin rod 160 with the electric push rod structure and the meshing groove 151 is used in this embodiment. Specifically, when the end of the clutch pin rod 160 engages with the meshing groove 151, the rotation of the threaded sleeve 150 inside the first roller seat 120 and the second roller seat 130 can be locked, ensuring the synchronous movement of the roller seats; when the clutch pin rod 160 is disengaged from the meshing groove 151, the threaded sleeve 150 can move freely inside the first roller seat 120 and the second roller seat 130, allowing the first roller seat 120 or the second roller seat 130 to move asynchronously when the bidirectional screw rod 300 rotates.

When the clutch pin rod 160 is retracted, the roller seat can move asynchronously, providing a flexible adjustment mode. This mode realizes accurate adjustment of the roll gap through the double-thread structure of the bidirectional screw rod 300, reduces wear, and prolongs the service life of the equipment. In the engaged state of the end of the clutch pin rod 160 and the meshing groove 151, the rotation of the threaded sleeve 150 inside the first roller seat 120 and the second roller seat 130 is locked, and the rotation of the bidirectional screw rod 300 is realized. The threaded sleeve 150 and the first roller seat 120, the second roller seat 130 are relatively stationary, and then through the rotation of the bidirectional screw rod 300, the first roller seat 120 and the second roller seat 130 move synchronously on the surface of the bidirectional screw rod 300, adjusting the roll gap; while in the disengaged state of the clutch pin rod 160 and the meshing groove 151, the threaded sleeve 150 can rotate relatively inside the first roller seat 120 and the second roller seat 130, and move freely, and then under the rotation of the bidirectional screw rod 300, the corresponding first roller seat 120 or second roller seat 130 is stationary, so as to realize the asynchronous movement of the first roller seat 120 or the second roller seat 130 by using the clutch control of the clutch pin rod 160.

The output end of the electric push rod is matched with the meshing groove 151 through a wedge head structure, which can realize precise control through simple mechanical means when adjusting the roll gap.

[0039] In order to further improve the adjustment accuracy and avoid structural looseness caused by wear, the threaded part of the bidirectional screw rod 300 in embodiment 2 is made of wear-resistant material, which can significantly improve the durability of the component and the long-term operation stability of the equipment.

[0040] Cooperation between structures:

[0041] Guide grooves are provided at both ends of the first roller seat 120 and the second roller seat 130, which cooperate with the bidirectional screw rod 300 to ensure that the first roller seat 120 and the second roller seat 130 can slide along the correct trajectory when adjusting the roll gap, avoiding deviation caused by guide problems.

[0042] The double-thread design on the bidirectional screw rod 300 allows the first roller seat 120 and the second roller seat 130 to move synchronously or asynchronously through reverse rotation, further improving the flexibility and accuracy of roll gap adjustment.

[0043] The utility model discloses through the structure and design of above -mentioned embodiment provides a kind of wave roller machine roll spacing adjustment mechanism, both can accurately adjust roll spacing, and can flexibly control the synchronous and non-synchronous movement of roll seat. Through the combination of electric push rod structure and the application of wear-resistant material, the accuracy of adjustment process and the durability of equipment are improved, with significant technical advantages.
