Specifically, the side wall of the upper pressing plate 301 and the side wall of the lower pressing plate 302 are connected by a hinge, so that the upper pressing plate 301 and the lower pressing plate 302 can be opened or buckled. Before production, the upper pressing plate 301 is opened, and after the sheet 600 is conveyed to the sheet preforming device 300, the upper pressing plate 301 is buckled and locked.

The invention has a simple structure, can effectively reduce the yellow spot smoke problem, realizes automatic convergence, and reduces the operating difficulties of operators.

[0048] Furthermore, squeezing rollers are provided on both sides of the second end of the sheet preforming device 300, and the surfaces of the rollers are coated with rubber or other elastic materials. The rollers are connected to spring mechanisms to fix both sides of the formed sheet 600. A pair of electric rollers can also be provided on both sides of the second end of the sheet preforming device 300, and the surfaces of the electric rollers are coated with rubber or other elastic materials. The electric rollers use bearings with adjustable distances, rotating arms and other mechanisms to adjust the pressure or spacing between the electric rollers, so as to provide the sheet 600 with a forward conveying force while maintaining the sheet 600 in a formed state.

[0049] In one embodiment of the system for processing the smoking substrate of a heated cigarette of the present invention, Figure 2 and Figure 3 As shown, the first pre-pressing assembly includes a first protrusion 3021 and a second protrusion 3022, which are extended along the length direction of the lower pressing plate 302 and are respectively located on both sides of the center line of the lower pressing plate 302, and a pressing groove 3023 is formed between the first protrusion 3021 and the second protrusion 3022.

[0050] The second pre-pressing assembly includes a third convex body 3011, a first groove 3012 and a second groove 3013. The third convex body 3011 is extended along the length direction of the upper pressing plate 301 and is located at the center line of the upper pressing plate 301. The third convex body 3011 is arranged opposite to the pressing groove 3023. The first groove 3012 and the second groove 3013 are located on both sides of the third convex body 3011. The first groove 3012 and the second groove 3013 are arranged opposite to the first convex body 3021 and the second convex body 3022 respectively.

[0051] Furthermore, the first convex body 3021, the second convex body 3022 and the third convex body 3011 are all V-shaped structures.

[0052] Specifically, the first convex body 3021 and the second convex body 3022 are higher than the end surface of the lower pressing plate 302 , the third convex body 3011 is higher than the end surface of the upper pressing plate 301 , and the first groove 3012 and the second groove 3013 are lower than the end surface of the upper pressing plate 301 .

[0053] When the upper pressing plate 301 and the lower pressing plate 302 are buckled with each other, the third protrusion 3011 is inserted into the pressing groove 3023 between the first protrusion 3021 and the second protrusion 3022, and the first protrusion 3021 and the second protrusion 3022 are respectively inserted into the first groove 3012 and the second groove 3013, and then through the interaction of the first protrusion 3021, the second protrusion 3022, the pressing groove 3023, the third protrusion 3011, the first groove 3012 and the second groove 3013, the sheet 600 located between the upper pressing plate 301 and the lower pressing plate 302 is squeezed into an M-shaped structure, so that the fragrance adding device 400 can spray the fragrance into the middle of the sheet 600 of the M-shaped structure, so that the fragrance can be preserved in the sheet 600 for a longer time.

[0054] It should be noted that the height of the first convex body 3021 and the height of the second convex body 3022 may be equal or unequal, which is not limited here.

[0055] When the height of the first protrusion 3021 is equal to the height of the second protrusion 3022 , that is, after the sheet 600 is extruded, both ends of the sheet 600 of the M-shaped structure are at the same height.

[0056] When the height of the first convex body 3021 is not equal to the height of the second convex body 3022 , that is, after the sheet 600 is extruded, the heights of the two ends of the sheet 600 of the M-shaped structure are different, and there is a position difference.

[0057] In one embodiment of the system for processing the smoking substrate of a heated cigarette of the present invention, Figure 2 and Figure 3As shown, the first end of the upper pressing plate 301 and the first end of the lower pressing plate 302 are configured to be close to the fragrance adding device 400, and the height of the first protrusion 3021, the height of the second protrusion 3022 and the height of the third protrusion 3011 are gradually reduced from the first end of the lower pressing plate 302 and the first end of the upper pressing plate 301 toward the second end of the lower pressing plate 302 and the second end of the upper pressing plate 301, respectively.

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

[0059] The present invention gradually reduces the height of the first convex body 3021, the height of the second convex body 3022 and the height of the third convex body 3011 from the first end of the lower pressing plate 302 and the first end of the upper pressing plate 301 toward the second end of the lower pressing plate 302 and the second end of the upper pressing plate 301, so that the thin sheet 600 has a buffer space when being conveyed by the conveying device 200 to the inside of the thin sheet preforming device 300, so that it is gradually squeezed into an M-shaped structure, effectively reducing the problem of damage to the thin sheet 600 and reducing the cost.

[0060] In one embodiment of the system for processing the smoking substrate of a heated cigarette of the present invention, Figure 2 and Figure 3 As shown, the first pre-pressing assembly further includes a third groove 3024 and a fourth groove 3025 . The third groove 3024 is disposed on the outer side of the first convex body 3021 , and the fourth groove 3025 is disposed on the outer side of the second convex body 3022 .

[0061] The second pre-pressing assembly further includes a fourth protrusion 3014 and a fifth protrusion 3015. The fourth protrusion 3014 is arranged on the outer surface of the first groove 3012, and the fifth protrusion 3015 is arranged on the outer side of the second groove 3013. The fourth protrusion 3014 and the fifth protrusion 3015 are arranged opposite to the third groove 3024 and the fourth groove 3025 respectively.

[0062] The present invention arranges the third groove 3024 on the outer side of the first convex body 3021, the fourth groove 3025 on the outer side of the second convex body 3022, and the fourth convex body 3014 on the outer side of the first groove 3012, and the fifth convex body 3015 on the outer side of the second groove 3013, and the fourth convex body 3014 and the fifth convex body 3015 are arranged opposite to the third groove 3024 and the fourth groove 3025 respectively, so that after the thin sheet 600 is processed by the first pre-pressing component and the second pre-pressing component, the entire thin sheet 600 can form a complete M-shaped structure.

[0063] In one embodiment of the system for processing the smoking substrate of a heated cigarette of the present invention, Figure 2 and Figure 3 As shown, the width of the third groove 3024 and the width of the fourth groove 3025 remain unchanged from the first end of the upper pressing plate 301 toward the second end of the upper pressing plate 301 , and then gradually increase.

[0064] The width of the fourth protrusion 3014 and the width of the fifth protrusion 3015 first remain unchanged from the first end of the lower pressing plate 302 toward the second end of the upper pressing plate 301 , and then gradually increase.

[0065] The present invention makes the width of the third groove 3024 and the width of the fourth groove 3025 remain unchanged from the first end of the upper pressure plate 301 toward the second end of the upper pressure plate 301, and then gradually increase them, and makes the width of the fourth protrusion 3014 and the width of the fifth protrusion 3015 remain unchanged from the first end of the lower pressure plate 302 toward the second end of the upper pressure plate 301, and then gradually increase them, so that the thin film 600 can be gradually extruded into an M-shaped structure in the upper pressure plate 301 and the lower pressure plate 302, thereby providing protection for the extrusion process of the thin film 600.

[0066] Furthermore, the height of the fourth protrusion 3014 and the height of the fifth protrusion 3015 are gradually reduced from the first end of the upper pressing plate 301 toward the second end of the upper pressing plate 301 .

[0067] The height of the third groove 3024 and the height of the fourth groove 3025 are gradually reduced from the first end of the lower pressing plate 302 toward the second end of the lower pressing plate 302 .

[0068] The present invention provides a buffering effect for the extrusion molding process of the thin film 600 by gradually reducing the height of the fourth protrusion 3014 and the height of the fifth protrusion 3015 from the first end of the upper pressure plate 301 toward the second end of the upper pressure plate 301, and gradually reducing the height of the third groove 3024 and the height of the fourth groove 3025 from the first end of the lower pressure plate 302 toward the second end of the lower pressure plate 302.

[0069] In one embodiment of the system for processing the smoking substrate of a heated cigarette of the present invention, Figure 2 and Figure 3 As shown, the outer wall of the third groove 3024 and the outer wall of the fourth groove 3025 are perpendicular to the end surface of the lower pressing plate 302, and the angle between the inner wall of the third groove 3024 and the inner wall of the fourth groove 3025 and the end surface of the lower pressing plate 302 is 30 degrees to 90 degrees.

[0070] The outer side wall of the fourth convex body 3014 and the outer side wall of the fifth convex body 3015 are perpendicular to the end surface of the upper pressing plate 301 , and the angle between the inner side wall of the fourth convex body 3014 and the inner side wall of the fifth convex body 3015 and the end surface of the upper pressing plate 301 is 30 degrees to 90 degrees.

[0071] It should be noted that if Figure 4 As shown, the angle between the inner side wall of the third groove 3024 and the inner side wall of the fourth groove 3025 and the end face of the lower pressure plate 302 is a. When the angle between the inner side wall of the third groove 3024 and the inner side wall of the fourth groove 3025 and the end face of the lower pressure plate 302 is 90 degrees, at this time, the inner side wall of the third groove 3024 and the inner side wall of the fourth groove 3025 are vertical to the end face of the lower pressure plate 302, and thus the side wall of the processed thin film 600 is vertical.

[0072] When the angle between the inner wall of the third groove 3024 and the inner wall of the fourth groove 3025 and the end face of the lower pressure plate 302 is greater than 30 degrees and less than 90 degrees, the inner wall of the third groove 3024 and the inner wall of the fourth groove 3025 are inclined, and thus the side wall of the processed thin film 600 is inclined.

[0073] In one embodiment of the system for processing the smoking substrate of a heated cigarette of the present invention, Figure 1 As shown, the sheet preforming device 300 also includes a handle 303, a locking plate and a clamping block. The handle 303 is arranged on the upper pressing plate 301. The first end of the locking plate is rotatably connected to the upper pressing plate 301. The locking plate has an opening. The clamping block is movably arranged on the lower pressing plate 302, and the clamping block passes through the opening.

[0074] The present invention arranges a handle 303 on the upper pressure plate 301, and the handle 303 can drive the upper pressure plate 301 to be opened or closed; and the first end of the locking plate is rotatably connected to the upper pressure plate 301, the locking plate has an opening, and a clamping block is movably arranged on the lower pressure plate 302, and the clamping block passes through the opening, and then the clamping block can be rotated to make the open interface clamped with the opening, thereby locking the upper pressure plate 301 and the lower pressure plate 302, so that the upper pressure plate 301 and the lower pressure plate 302 can extrude the thin film 600 into a preset structure.

[0075] In one embodiment of the heated cigarette smoking matrix processing system of the present invention, the conveying device 200 includes a plurality of conveying rollers 201, two limiting rollers 202, two slitting rollers 203 and two guide rollers 204 arranged at one time, and the plurality of conveying rollers 201 are arranged at intervals for conveying the thin sheet 600 to the limiting rollers 202, and the two limiting rollers 202, the two slitting rollers 203 and the two guide rollers 204 are respectively arranged on both sides of the thin sheet 600.

[0076] Specifically, after the reel unwinding device 100 unwinds, the reel roller 101 rotates and unwinds, and then the reel is stretched and flattened by a plurality of conveying rollers 201, which are driven by a servo motor. The stretched and flattened sheet 600 is flattened and limited by two limiting rollers 202 to prevent the sheet 600 from swinging and causing problems such as the sheet 600 being broken or cut.

[0077] Next, the sheet 600 is limited by the limiting roller 202 and then enters the slitting roller 203 for pressing and cutting, which is conducive to contraction; the slitting roller 203 is a mature technology in the industry and is not limited here; after the sheet 600 is pressed and cut, a continuous sheet 600 with indentations is formed, and the sheet 600 is in a complete state.
