A guide block 85 is fixedly connected to the bottom of the connecting rod 84. The guide block 85 is slidably connected to the fixed base 2. A sliding groove 86 is opened inside the fixed base 2. The guide block 85 is slidably connected inside the sliding groove 86. By designing the sliding groove 86, the guide block 85 can slide inside the sliding groove 86. A connecting frame 87 is fixedly connected to the outside of the connecting rod 84. A roller 88 is rotatably sleeved inside the connecting frame 87 through a bearing. By designing the stretching mechanism 8, it is convenient to stretch the tobacco film.

[0022] Please see Figure 1 , Figure 2, Figure 3 , Figure 4 The limiting mechanism 9 includes a groove 91. The fixed base 2 has a groove 91 inside. A retaining ball 92 is movably sleeved inside the groove 91. There are multiple grooves 91, which are arranged in a ring and evenly distributed inside the fixed base 2. By designing multiple grooves 91, the retaining ball 92 can be inserted into the grooves 91 at different positions. The retaining ball 92 is movably connected to the turntable 4. A slider 93 is movably sleeved on the outside of the retaining ball 92. The slider 93 is slidably connected to the turntable 4. A spring 94 is fixedly connected on the outside of the slider 93. The spring 94 is fixedly connected to the turntable 4. A guide rod 95 is slidably sleeved inside the slider 93. The guide rod 95 is fixedly connected to the turntable 4. A spring 96 is provided on the outside of the guide rod 95. One end of the spring 96 is fixedly connected to the slider 93, and the other end of the spring 94 is fixedly connected to the turntable 4. By designing the spring 96, the force of the spring 96 can act on the slider 93. By designing the limiting mechanism 9, it is convenient to limit and fix the turntable 4.

[0023] The specific implementation process of this utility model is as follows: In use, the tobacco film is placed on the surface of the turntable 4, and then the electric push rod 81 is started. The output end of the electric push rod 81 drives the dual-axis motor 82, which drives the screw 83 and the connecting rod 84 to move downward. The connecting rod 84 drives the connecting frame 87 to move downward, so that the roller 88 contacts the tobacco film. Then, the dual-axis motor 82 is started, and the output end of the dual-axis motor 82 drives the screw 83 to rotate, so that the connecting rod 84 makes a threaded movement. The connecting rod 84 drives the guide block 85 to slide along the slide groove 86, so that the connecting rod 84 pulls the connecting frame 87 and the roller 88 to roll along the tobacco film, thus stretching the tobacco film. When one side is stretched, the roller 88 moves upward and separates from the tobacco film. Then, the rotating motor 3 is started, and the output end of the rotating motor 3 drives the turntable 4 to rotate. The turntable 4 drives the tobacco film to rotate, and then the other side of the tobacco film can be stretched again by moving the roller 88. This facilitates bidirectional stretching of the tobacco film without the need for manual adjustment of the stretching direction, making it convenient to use.

[0024] During the rotation of the turntable 4, the turntable 4 drives the retaining ball 92 to rotate. The retaining ball 92 rolls along the arc surface of the groove 91. The retaining ball 92 is squeezed and pushed into the turntable 4. The retaining ball 92 drives the slider 93 to move horizontally. The slider 93 slides along the guide rod 95 and squeezes the spring 96. At the same time, the slider 93 squeezes the elastic ball 94, which can separate the retaining ball 92 from the groove 91. As the turntable 4 rotates, the elasticity of the spring 96 will give the slider 93 a reverse thrust, which can push the retaining ball 92 into the groove 91 at another position. At this time, the turntable 4 can be limited after rotation to prevent the wobbling and movement of the turntable 4 during the edge cutting process from affecting the edge cutting effect. After stretching is completed, the electric push rod 81 drives the cutter 11 to move down to complete the edge cutting of the tobacco film.
