Example 2

Inner and outer frames simultaneously (bilateral) working mode: as shown in fig. 8 and 11, in operation, the medical collagen sponge tablet press of the present invention is first adjusted to an initial working state, in which the outer frame 35 is perpendicular to the inner frame 37 and both are perpendicular to the ground. When the motor 22 runs, the outer frame 35 and the inner frame 37 are respectively driven by the transmission mechanism to turn over for 90 degrees;

as shown in fig. 9 and 10, the outer frame 35 and the inner frame 37 gradually move to a parallel state, in which the planes of the outer frame 35 and the inner frame 37 are overlapped, and both the outer frame 35 and the inner frame 37 are parallel to the ground and perpendicular to the vertical support rod 12.

Example 3

According to the thickness of the sponge cutting block, firstly, rough pressing is carried out, the sponge cutting block is quickly pressed to the specified thickness by using the unilateral working mode in the embodiment 1, then, fine pressing is carried out, and the thicknesses of four corners of the sponge cutting block are pressed to the specified thickness by using the bilateral working mode in the embodiment 2.

The device can derive 2 different working methods with the same structure, and respectively carries out unilateral pressing or bilateral pressing on the bottom medical collagen sponge piece cut pieces. When the edges are pressed singly, the sponge blocks are compressed more quickly, but the surface is uneven; in the bilateral pressing, the pressed surface is relatively flat because 2 vertical edges of one corner are pressed, but the compression speed of the sponge blocks is relatively slow because pressure is applied to the corners. Therefore, the two working methods have respective advantages and disadvantages.

Therefore, different pressing working modes can be selected according to different density sponge pieces and the requirements of pressing force and speed. The single-side method is adopted when the rapid pressing is needed, and the double-side working method is adopted when the upper surface is smooth. The two working modes can be sequentially used, the specified thickness is pressed by adopting unilateral express delivery, and then the flatness of the upper surface is adjusted by adopting a bilateral working method. When the two working methods are exchanged, the equipment does not need to be adjusted, and only different initial positions need to be debugged. Therefore, the equipment has very high working flexibility, different working modes can be achieved without modifying the equipment, and the process adjustment is very flexible and mobile.

The above-described embodiments further explain the object, technical means, and advantageous effects of the present invention in detail. It should be understood that the above description is only exemplary of the present invention, and is not intended to limit the scope of the present invention.
