[0020] Referring to the accompanying drawings, in an embodiment of the present embodiment, the pressure regulating device of the pressing mechanism can be used in equipment such as die-cutting, creasing, and hot stamping, and includes a lower mounting plate 2, an upper mounting plate 4, and an upper support plate 5. The lower mounting plate 2 is provided for the installation of the lower mold 1, and the upper mounting plate 4 is provided for the installation of the upper mold 3; the upper support plate 5 is located on the upper side of the upper mounting plate 4, and the lower mounting plate 2 is located on the lower side of the upper mounting plate 4. The upper mounting plate 4 is also provided with a lifting guide component 6, that is, the upper mounting plate 4 is located between the upper support plate 5 and the lower mounting plate 2 for lifting and lowering, so that the upper mold 3 installed thereon cooperates with the lower mold 1 to close and separate.

[0021] A closing and pressing driving assembly 7 is connected between the upper support plate 5 and the upper mounting plate 4, and the closing and pressing driving assembly 7 drives the upper mounting plate 4 to move up and down, so that the upper mounting plate 4 moves toward and apart from the lower mounting plate 2, so that the corresponding molds (upper mold 3 and lower mold 1) can be closed and opened. The upper support plate 5 can be used to support the closing and pressing driving assembly 7 and the upper mounting plate 4 to operate.

[0022] The pressing drive assembly 7 includes an eccentric drive shaft 8 , a rotary drive motor 9 , a connecting rod 10 and an eccentric transmission shaft 11 .

[0023] Among them, a first rotating 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 rotating support seat 12. The first rotating support seat 12 cooperates with and supports the eccentric drive shaft 8 to rotate (rotate) so as to rotate and drive. The rotating drive motor 9 is arranged on the upper support plate 5 (can be connected to its first rotating support seat 12). The rotating drive motor 9 is transmission-connected with the eccentric drive shaft 8, and the rotating drive motor 9 cooperates with and drives the eccentric drive shaft 8 to rotate on the first rotating support seat 12.

[0024] Among them, a second rotating 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 rotating support seat 13, and the second rotating support seat 13 cooperates with the eccentric transmission shaft 11 to rotate, so as to rotate and adjust the pressure.

The eccentric drive shaft 8 and the eccentric transmission shaft 11 are connected by the connecting rod 10 through transmission.

[0026] During operation, the rotary drive motor 9 drives the eccentric drive shaft 8 to rotate on the first rotary support seat 12 of the upper support plate 5. 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, thereby cooperating with the second rotary support seat 13 and the upper mounting plate 4 to rise and fall together. When pressure adjustment is required, the position of the eccentric transmission shaft 11 can be rotated.

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, and the rotation adjustment drive motor 18 can be connected to the upper mounting plate 4 (which can be equipped with a motor seat 28 for matching assembly), and the transmission connection between the rotation adjustment drive motor 18 and the worm 15 can be a sprocket chain drive or a gear drive or a belt drive. In the figure, a first sprocket 29 is arranged on the output shaft of the rotation adjustment drive motor 18, and a second sprocket 30 is arranged on the worm 15. The first sprocket 29 and the second sprocket 30 are connected by a chain drive, wherein not only can the rotation adjustment drive motor 18 cooperate to drive the operation, but also can be operated by electronic control, and can realize online adjustment, real-time adjustment during the pressing process and the production process, and real-time observation of the adjustment effect, and observation of the quality of the product after the pressure of the pressing is adjusted, so as to facilitate continuous debugging.

[0030] In order to run more smoothly and have a longer service life, a first bearing 19 is provided between the eccentric drive shaft 8 and the first rotating support seat 12, a second bearing 20 is provided between the eccentric transmission shaft 11 and the second rotating support seat 13, a third bearing 21 is provided between the connecting rod 10 and the eccentric drive shaft 8, and a fourth bearing 22 is provided between the connecting rod 10 and the eccentric transmission shaft 11.

[0032] In addition, the upper support plate 5 can also be connected to the column 23, and the column 23 is used for the installation of the upper support plate 5. For example, the upper support plate 5 has a connecting hole that is sleeved on the column 23 and locked by a nut (nuts can be respectively configured on the upper and lower parts of the upper support plate 5 for locking to facilitate fine-tuning of the position up and down); the column 23 can even be installed on the lower mounting plate 2, and the column 23, the upper support plate 5, the pressing drive assembly 7, the upper mounting plate 4 and the upper mold 3 installed thereon can all be adjusted together with the lower mounting plate 2 (such as front and back, left and right, rotation angle, etc.), which is more practical, so that the pressing position of the material can be relatively more accurate to avoid misprints (such as the pressing position is inconsistent with the position of the text and image on the material). During assembly, additional planar thrust bearings (which can be sleeved on the eccentric drive shaft 8) can be provided on the left and right sides of the connecting rod 10. In addition, an axial retaining ring or a step can be provided on the left or right side of the connecting rod 10 to facilitate connection with the eccentric drive shaft 8 (cooperating for axial limiting). The column 23 and the upper support plate 5 can be locked by a nut. For example, the upper support plate 5 has an assembly through hole, and the upper end of the column 23 has an external thread. The upper end of the column 23 passes through the assembly through hole, and nuts are respectively provided on the upper and lower sides of the upper support plate 5 for connecting and fixing the upper support plate 5.
