[0037] In addition, a first connecting hole is provided on the lower mounting plate 2, a second connecting hole is provided on the rotating plate 31, and a third connecting hole is provided on the lower support plate 26. The first connecting hole, the second connecting hole and the third connecting hole are connected by a connecting member, and the second connecting hole and the third connecting hole have reserved space for radial adjustment activities of the connecting member; the connecting member includes a connecting bolt, and the connecting bolt is equipped with a nut.

[0038] For example, the pressing drive assembly 7 includes a hydraulic cylinder or a pneumatic cylinder or a motor, and the upper mounting plate 4 is provided with a lifting guide component 6 , which can directly adopt the column 23 or adopt a guide rail arranged on the upper support plate 5 .

[0039] For example, the combined pressure drive assembly 7 includes an eccentric drive shaft 8, a rotation drive motor 9, a connecting rod 10 and an eccentric transmission shaft 11. Among them, a first rotation support seat 12 is provided on the lower side of the upper support plate 5, and the eccentric drive shaft 8 is arranged on the first rotation support seat 12. The first rotation support seat 12 cooperates with the eccentric drive shaft 8 to rotate (rotate) so as to rotate and drive.

Among them, a second rotation support seat 13 is provided on the upper side of the upper mounting plate 4, and the eccentric transmission shaft 11 is arranged on the second rotation support seat 13. The second rotation support seat 13 cooperates with the eccentric transmission shaft 11 to rotate so as to rotate and adjust the pressure. The eccentric transmission shaft 11 is also connected in a transmission manner to a rotation adjustment driving component 14, and the rotation adjustment driving component 14 cooperates to drive the eccentric rotating shaft to rotate and adjust the corresponding position. Among them, the upper transmission sleeve of the connecting rod 10 is arranged on the eccentric part A of the eccentric drive shaft 8, and the lower transmission sleeve of the connecting rod 10 is arranged on the eccentric part B of the eccentric transmission shaft 11, and the eccentric drive shaft 8 and the eccentric transmission shaft 11 are connected by the connecting rod 10 in a transmission manner. During operation, the eccentric drive shaft 8 is driven by the rotary drive motor 9 to rotate on the first rotary support seat 12 of the upper support plate 5, and the rotation of the eccentric drive shaft 8 drives the connecting rod 10 to operate, and the connecting rod 10 drives the eccentric transmission shaft 11 to rise and fall, and cooperates to make the second rotary support seat 13 and the upper mounting plate 4 rise and fall together; when pressure adjustment is required, the position of the eccentric transmission shaft 11 can be rotated. The closing pressure driving assembly 7 of the position adjustment device of the closing pressure mechanism can not only realize the closing pressure operation (including closing and separating), but also realize (closing pressure) pressure adjustment; wherein the eccentric transmission shaft 11 plays a transmission coordination role (so that the rotary drive motor 9 drives the upper mounting plate 4 to rise and fall), and the rotation adjustment coordination of the eccentric transmission shaft 11 will also realize pressure adjustment, and its pressure adjustment stability and accuracy are relatively high.

[0040] There are many ways for the rotation adjustment driving component 14 to drive the eccentric transmission shaft 11 to rotate on the second rotation support seat 13 of the upper mounting plate 4, and a gear pair structure or a belt transmission pair can be used.

The worm 15 can be arranged vertically or horizontally. It can also be optimized, for example, the worm 15 is provided with a manual rotation operation part (such as a wrench head); or the worm 15 is equipped with a rotation adjustment drive motor 18, which drives the worm 15 to rotate. The rotation adjustment drive motor 18 can be connected to the upper mounting plate 4, which can not only be driven by the rotation adjustment drive motor 18, but also can be operated by electric control, and can realize online adjustment, real-time adjustment during the pressing process and production process, and real-time observation of the adjustment effect, and observation of the quality of the product after adjusting the pressing pressure, so as to facilitate continuous debugging.
