By rotating the threaded fastener, the user can adjust and lock the heating plate to the desired angle. The first pressing portion 621 is provided on the first threaded fastener 62. When the first threaded fastener 62 is tightened with the first threaded hole 61, the first pressing portion 621 will apply pressure to the first movable frame 3 to ensure that the heating plate remains stable during the heating process and avoid uneven heating due to vibration or slippage.

[0030] The support frame 2 is provided with an installation opening 21, and the second locking structure 7 includes a second threaded hole 71 provided on the first heating plate 41 and the second heating plate 42, and a second threaded fastener 72 passing through the installation opening 21 and capable of cooperating with the second threaded hole 71, and the second threaded fastener 72 is provided with a second pressing portion 721 which can press the support frame 2 when cooperating with the second threaded hole 71, thereby limiting the relative movement between the second threaded fastener 72 and the support frame 2.

In the embodiment, the first heating plate 41 and the second heating plate 42 are initially arranged parallel to each other when installed on the first movable frame 3 and the second movable frame 8. The arrangement of the second movable frame 8 enables the first heating plate 41 and the second heating plate 42 to maintain relative parallelism when adjusting the angle, thereby ensuring heating uniformity.

The standardization and repeated setting of the structure make the adjustment of the heating plate convenient. The user can quickly adjust the position of the heating plate according to production requirements.

[0039] A heating gap 43 is left between the first heating plate 41 and the second heating plate 42 for the copper-clad plate to pass through, and the numerical control component 5 includes temperature sensors 51 respectively arranged in the first heating plate 41, the second heating plate 42, the inlet end of the heating gap 43, and the outlet end of the heating gap 43.

[0041] In the embodiment, a temperature sensor 51 is also provided in the middle of the heating gap 43 to facilitate more comprehensive monitoring of temperature changes.

[0042] In the embodiment, the temperature sensors 51 at the inlet and outlet ends of the heating gap 43 are respectively connected to the two movable frames in a sliding manner in the up-down direction, and the temperature sensor 51 in the middle of the heating gap 43 is connected to the support frame 2 in a sliding manner in the up-down direction to cooperate with the free adjustment of the heating plate and adapt to the precise temperature sensing of different heating paths. Through the position arrangement of the temperature sensor 51, the temperature is accurately collected, and then the processing temperature is accurately controlled to achieve refined and accurate processing.

[0043] In the embodiment, the support frame 2 is provided with a height scale to accurately measure the height of each component on the support frame.

[0048] The lower part of the seat body 1 is provided with a pulley assembly 10 that enables the device to move on a plane.

[0049] By setting the pulley assembly 10, the entire preheating device can be easily moved on the plane of the factory workshop without the aid of a forklift or other heavy handling equipment, which greatly improves the flexibility and operability of the equipment and adapts to different production layouts and process changes.

[0050] The pulley assembly 10 is provided with a braking structure capable of limiting the rotation of the pulley.

[0051] The braking structure can be implemented by a braking device near the pulley or integrated in the pulley structure.
