That is, the four molding die assemblies in the molding die unit 4 are respectively guided and positioned accurately through the guide grooves, and it is also convenient to replace molding die assemblies of different specifications.

[0050] The present application does not impose any specific restrictions on the specific configuration of the first guide groove, the second guide groove, the third guide groove, and the fourth guide groove. Figure 4As shown, the first guide groove w located at the top of the upper front pressing plate 21 can adopt a dovetail groove structure. Similarly, the second guide groove, the third guide groove and the fourth guide groove can also adopt a dovetail groove structure.

[0054] As shown, taking the connection between the left drive device 9 and the left die guide assembly 5 as an example, in some possible implementations, the left drive device 9 can use a servo motor, and the output end of the servo motor is connected to the input end (such as a screw) of the left die guide assembly 5 through a synchronous belt and a synchronous wheel. Similarly, the connection between the right, front, and rear drive devices (10, 11, 12) and the right, front, and rear die guide assemblies (6, 7, 8) is not repeated here.

[0055] The automatic cigarette clamping and forming mechanism of the present application is a core component of the special-shaped cigarette forming equipment. It is located between the tobacco returning mechanism and the cigarette shaping length adjustment mechanism inside the equipment. When the cigarette falls into the forming mold assembly, the cigarette shaping length adjustment mechanism is used to limit the falling depth. At the same time, the tobacco returning mechanism extends the ejector rod from the direction of the cigarette into the forming mold assembly until the ejector rod contacts the cigarette. At this time, the front pressing plate and the rear pressing plate are clamped under the guidance of the left, right, front and rear pressing die guide assemblies driven by the left, right, front and rear driving devices, and the real-time closed-loop control of the clamping position is realized through the displacement sensor to ensure the cigarette forming effect.

[0057] According to needs, the depth of the cigarette falling into the forming mold assembly can be adjusted, thereby automatically completing the production of filter segments and cigarette segments with "round sky and square earth" (one end is round and the other end is square) and fully square cigarettes.

[0058] In some embodiments, the production capacity of the special-shaped cigarette forming equipment using the automatic mold closing and forming mechanism of the present application reaches: 250 cigarettes / min.

[0059] The specific configuration of the front die guide assembly 7 and the rear die guide assembly 8 will be further described below.

[0063] In some possible implementations, in order to limit the moving distance of the guide mounting block 76 in the direction away from the front die plate 2, as Figure 5 As shown, the front die guide assembly 7 also includes a limiting bumper 77 ; the limiting bumper 77 is arranged on the left side of the guide mounting block 76 .

[0064] In addition, the specific arrangement of the left die guide assembly 5 and the right die guide assembly 6 is further described below. Figure 2 As shown, the structures of the left die guide assembly 5 and the right die guide assembly 6 are the same, and the left die guide assembly 5 is taken as an example for explanation.

[0068] It should be noted here that although the structural settings of the left die guide assembly 5 and the right die guide assembly 6 are basically the same, they will not be repeated here. For the specific structure of the right die guide assembly 6, reference can be made to the relevant settings of the aforementioned left die guide assembly 5.

[0069] The right die guide assembly 6 is different from the left die guide assembly 5 in that:
