Meanwhile, the sealing box 191 is covered with the protection box 22, and the inner wall of the protection box 22 is bonded with an insulating layer, so as to prevent the adjusting component 19 from generating electric leakage and further causing accidents. In this embodiment, two sets of rollers may be added to the bottom of the protection box 22, and each set of rollers includes two rollers, so as to move the adjustment assembly.
The overall working process is as follows: when the servo motor 131 works, the large screw 132 and the small screw 133 are driven to rotate, the pressing plate 5, the buffer plate 6 and the hot pressing device 4 can be driven to lift, when a heated object is pressed, the servo motor 131 drives the large screw 132 to rotate, so that the pressing plate 5 and the buffer plate 6 descend along the large screw 132, the hot pressing device 4 descends along the small screw 133, when the hot pressing device 4 descends until the hot pressing plate 43 is pressed against the heated object, the small screw 133 is separated from the second threaded sleeve 15 of the connecting plate 42, so that when the large screw 132 rotates and further drives the small screw 133 to rotate, the connecting plate 42 does not influence the rotation of the small screw 133; when the buffer plate 6 is lowered to be separated from the large screw 132 (when the buffer plate 6 is separated from the large screw 132 so that the buffer plate 6 abuts against the connecting plate 42 of the hot-pressing device 4, the first thread bushing 14 on the buffer plate 6 is located at the small screw 133, so that the large screw 132 cannot drive the buffer plate 6 to continuously press down due to rotation), the buffer plate 6 is connected with the pressing plate 5 through an elastic buffer member so that the pressing plate 5 can drive the buffer plate 6 to continuously descend along the screw, when the buffer plate 6 is lowered to abut against the connecting plate 42 of the hot-pressing device 4, the buffer plate 6 and the connecting plate 42 are relatively fixed so that the pressing plate 5 continuously descends to provide a downward force to the hot-pressing device 4, so as to press and process the heated object, and when the pressing plate 5 descends, because the distance between the pressing plate 5 and the buffer plate 6 is reduced, the spring 8 is compressed, the spring 8 is compressed by force to generate restoring force to offset part of impact force, thereby playing a role in buffering; after the press-fit, the servo motor 131 drives the large screw 132 to rotate, so that the pressing plate 5 rises along the large screw 132, the pressing plate 5 is connected with the buffer plate 6 through the elastic buffer, the buffer plate 6 can rise to the first thread sleeve 14 to be in thread fit with the large screw 132, and the buffer plate 6 rises to drive the hot press device 4 to rise to the second thread sleeve 15 to be in thread fit with the small screw 133.
The above-mentioned embodiments are merely illustrative and not restrictive, and those skilled in the art can make modifications to the embodiments without inventive contribution as required after reading the present specification, but only protected by the patent laws within the scope of the claims.
