Detailed ways

The present application is described in detail below with reference to embodiments, but the present application is not limited to these embodiments.

Device Example 1

The equipment includes: 1-processing platform, 2-automatic processing operation table, 3-horizontal x-axis movement controller, 4-horizontal x-axis movement slide, 5-processing tool head controller set, 6-tool head vertical movement chain assembly, 7-vertical y-axis movement slide, 8-vertical y-axis movement controller, 9-downward pressure processing tool head, 10-infrared temperature measuring gun, 11-sample processing area, 12-front and rear z-axis movement slide, 13-support slide, 14-tool head transmission controller, 15-transmission shaft, 16-roller cover. The automated processing operating table is integrated with a digital control and operating system, which can independently control and operate each unit system of the equipment. In addition, the equipment is equipped with a manual adjustment kit, which can be manually adjusted in time as needed. In order to simplify the schematic diagram, this part is not drawn; the processing tool head controller kit includes a tool head drive controller and a reducer. When necessary, the reducer can be turned on to protect the unit, and torque overload can also be avoided to prevent processing failure; the sample processing area integrates a heating unit, a temperature measuring thermocouple and a sample holder from bottom to top, and there are also semi-enclosed baffles around it to prevent sample breakage and splashing; the downward pressing processing tool head is a roller tool group that can rotate at a predetermined angular velocity. The tool head will directly contact the surface of the sample and perform downward pressing and rolling processing according to the set trajectory.

The 5-processing cutter head controller set (i.e., the speed control device) will be linked with the integrated pressure sensor. If the processing pressure exceeds the threshold, the speed and pressure regulation can be started to protect the unit and avoid processing failure caused by torque overload; 15-the transmission shaft adopts a composite design of rolling shaft and load-bearing shaft, which increases the pressure while ensuring the smooth operation of the roller tool; 9-the downward pressure processing head (i.e., the rolling cutter head) is composed of a roller body and a surface thread. The surface thread is designed as an externally embedded convex surface that is approximately semicircular, which can increase the shear force between the tool and the plate surface during processing, reduce the friction contact area, and effectively reduce the generation of friction heat.

Place the plastic sheet to be processed on the sample processing area (i.e., sample platform) 11; set the position and speed of the pressing tool head (i.e., rolling tool head) 9 and the operation of the heating module 10 through the automated processing operation table 2; perform the operation according to the established parameters to perform surface processing on the plastic sheet to be processed. During the processing, if the processing pressure exceeds the threshold, the equipment and sample are protected through the tool head controller set (i.e., speed control device) 5.

The above are only a few embodiments of the present application and do not constitute any form of limitation to the present application. Although the present application is disclosed as above with preferred embodiments, it is not intended to limit the present application.
