[0058] Specifically, the depth of the pressing groove 3023, the depth of the first recess 3012 and the depth of the second recess 3013 are gradually reduced from the first end of the lower pressing plate 302 and the first end of the upper pressing plate 301 respectively, towards the second end of the lower pressing plate 302 and the second end of the upper pressing plate 301.

[0059] The present application gradually reduces the height of the first protrusion 3021, the height of the second protrusion 3022 and the height of the third protrusion 3011 from the first end of the lower pressing plate 302 and the first end of the upper pressing plate 301 respectively, towards the second end of the lower pressing plate 302 and the second end of the upper pressing plate 301, so that the sheet 600 can have a buffer space when being conveyed by the conveying device 200 into the sheet preforming device 300, thereby being gradually extruded into an M-shaped structure, effectively reducing the problem of sheet 600 damage, reducing cost,

[0060] In one embodiment of the heating cigarette smoking substrate processing system of the present application, as shown in Figure 2 and Figure 3 As shown, the first pre-pressing assembly further comprises a third recess 3024 and a fourth recess 3025, the third recess 3024 is arranged outside the first protrusion 3021, and the fourth recess 3025 is arranged outside the second protrusion 3022.
