[0034] Example 2

[0035] On the basis of embodiment 1, the heating devices in each closed space are connected in parallel, and the heating devices are uniformly distributed around the inner mold close to the blade head. The heating devices in the closed space are connected by a separate power bus. The separate power bus facilitates fine control of the knife mold and improves the control accuracy of the knife mold. At least one temperature sensor is installed on one side of the power bus in the separate closed knife mold to facilitate temperature monitoring of the closed knife mold space. In addition, the constant temperature of the heating device is 300 degrees, and the constant temperature of the heating device can basically meet the hot cutting of the knife mold. In addition, the outer mold of the hot cutting plastic suction knife mold is coated with a silicone resin heat insulation coating to prevent the operator from being injured due to the high temperature of the outer mold of the knife mold. At the same time, the coating has a heat insulation effect to prevent the knife mold from leaking heat and to prevent the knife mold from being heated frequently to maintain a constant temperature.

[0036] Embodiment 3

[0037] According to Figure 6 As shown in FIG. 3, on the basis of embodiment 2, the hot cutting plastic suction knife mold is further connected with a temperature controller. The temperature controller is separately connected with the power bus to form an independent control loop. The temperature controller includes a single-chip microcomputer and a relay. The signal input end of the single-chip microcomputer is connected with the temperature sensor to receive the temperature signal. The signal output end of the single-chip microcomputer is connected with the control end of the relay to control the closing of the heating circuit. The wiring end of the relay is in communication with the heating device and the power bus to form an independent loop for separately controlling the temperature in each closed space of the knife mold. In addition, the single-chip microcomputer is externally connected with a button and a display panel for setting the threshold value of the heating sheet. The independent control loop sets the threshold value of the heating sheet. The threshold value can be selected and set for the separate knife mold space to realize the separate control of the temperature in the independent knife mold space. PET sheet is commonly used for hot cutting. According to the thickness of the sheet, when the thickness is 0.2 to 0.5 mm, the temperature of the knife head is heated to 180 to 220. When the thickness is 0.5 to 1 mm, the temperature of the knife head is heated to 260 to 280. After the temperature control loop is turned on, the threshold value of the single-chip microcomputer is set. The single-chip microcomputer calculates and processes the temperature data received by the temperature sensor. When the temperature reaches the threshold value, the loop is disconnected. When the temperature is below the threshold value, the loop is closed. The on-off of the temperature threshold control line is realized to keep the temperature of the knife mold constant.
