[0008] 1. When performing the perforation process on the mushroom sticks, the No. 2 perforation wheel and the No. 1 perforation wheel array are arranged in a ring. This ensures that the mushroom sticks are perforated evenly all over as they pass through the No. 2 perforation wheel array. The ring design with the No. 2 and No. 1 perforation wheels meshing with each other ensures that all the No. 2 and No. 1 perforation wheels move synchronously, making the force on the mushroom sticks more uniform during the perforation process. This avoids local damage to the mushroom sticks due to uneven force and ensures the perforation effect.

[0009] 2. Both the No. 2 and No. 1 opening wheels of this utility model are equipped with two sets of opening needles. Compared with only a single set of opening needles, the double set of opening needles can ensure the opening density of the mushroom sticks while setting fewer opening wheels, thereby reducing the number of transmission stages of the opening wheels, making the movement of the opening wheels more stable, making the mushroom sticks more evenly stressed during the opening process, and achieving better opening effect.

[0010] 3. In this utility model, the outer linkage wheel mounting base and the inner linkage wheel mounting base of a single set are fixedly connected by a fastening screw and limited by a limiting screw and a limiting spring connecting mechanism. The limiting screw and the limiting spring connecting mechanism can cause the No. 2 perforated wheel and the No. 1 perforated wheel array group to produce a certain deformation after being subjected to force, ensuring that the perforated wheel array group can expand to a certain extent when processing larger mushroom sticks. This allows the device to process mushroom sticks of various sizes, increasing the adaptability of the device.

[0011] 4. The top of the outer linkage wheel mounting base on both sides of this utility model is fixedly connected to the linkage mechanism support platform, so that the second linkage shaft and the drive gear connected to the linkage mechanism support platform will move synchronously with the outer linkage wheel mounting base during the movement of the outer linkage wheel mounting base. This ensures that the drive gear and the driven gear at the corresponding position always maintain meshing, while also ensuring that the drive gear will not be subjected to excessive pressure due to the movement of the driven gear.
