[0010] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0011] Embodiment 1: A flower tube cutting machine for fireworks production, such as Figure 1-Figure 3As shown, it includes a base frame, a limit plate, a bracket, an electric push rod, a pressure frame, a spring, a fixed frame, a grinding block, a rotating rod, a cutter, a gear, a rack, a slide plate, an inclined plate and a collection box. The upper part of the base frame is welded with a limit plate, and the limit plate is provided with a plurality of semicircular grooves 1. The upper part of the base frame is connected with a bracket through rivets, and an electric push rod is welded with the upper part of the bracket. The telescopic rod of the electric push rod passes through the bracket, and the upper part of the bracket is slidably connected with a pressure frame, and the pressure frame is fixedly connected to the telescopic rod of the electric push rod. The bottom of the pressure frame is provided with a plurality of semicircular grooves 2, and the semicircular grooves 2 at the bottom of the pressure frame are located directly above the semicircular grooves 1 of the limit plate. Two springs are connected to the bracket through a hook, and the other ends of the two springs are connected to a fixed The frame is in contact with the pressing frame, the lower part of the fixed frame is connected with a grinding block by bolts, the interior of the grinding block is an arc-shaped structure, the lower part of the fixed frame is rotatably connected with a rotating rod, a cutting knife is welded on the rotating rod, and the cutting knife will contact the grinding block, one end of the rotating rod is connected with a gear through a flat key, a rack is welded on one side of the bracket, the rack is meshed with the gear, a slide plate is welded on one side of the bracket, a limiting hole is opened on the slide plate, one end of the rotating rod passes through the limiting hole of the slide plate, and the limiting hole of the slide plate is used to limit the rotating rod, an inclined plate is welded on the side of the base frame close to the bracket, the inclined plate facilitates the falling of the cut flower tube, and a collecting box is connected with the side of the base frame close to the bracket by bolts, the collecting box is fixedly connected to the inclined plate, and the inclined plate is located above the collecting box.
