This utility model relates to a fireworks inner tube buffer device, installation equipment, and fireworks production line. The fireworks inner tube buffer device includes: a first conveyor line for conveying fireworks inner tubes; a second conveyor line disposed below the first conveyor line, including spaced-apart material distribution troughs for receiving fireworks inner tubes and transferring them to the next process; and a buffer assembly located in the transition area between the first and second conveyor lines and disposed on the second conveyor line for guiding fireworks inner tubes from the first conveyor line into the material distribution troughs of the second conveyor line. The fireworks inner tube buffer device provided in this application can achieve smooth introduction of fireworks inner tubes and has buffering and material distribution functions.

The application discloses a watchband laser cutting device and a cutting method. A work round table is arranged, and a plurality of positioning clamps are arranged on one side of the work round table. The work round table is matched with a feeding mechanism, a laser cutting mechanism and a discharging mechanism, and work is performed between the corresponding positioning clamps, so that the watchband to be processed can sequentially complete the feeding, positioning, cutting and discharging processes, thereby forming a continuous and orderly processing flow. The positioning clamp is formed by a fixed block and two clamping plates, and the clamping space gradually increases in the direction away from the surface of the fixed block, so that the watchband can be more smoothly introduced into the clamping area when entering the positioning clamp, and better guiding and limiting effects are obtained during the entering process, thereby improving the stability and consistency of the watchband placement posture, reducing the occurrence of inclination, lifting or inaccurate positioning of the watchband in the processing area, and thereby maintaining high corresponding precision between the laser cutting position and the predetermined processing area.

A mixed-flow ventilation fan includes a base plate and a panel that snaps onto it. An exhaust pipe is connected to the rear of the base plate. An air inlet is provided on the panel, communicating with the exhaust pipe on the base plate. A motor mount is connected to the inner wall of the exhaust pipe via several guide vanes. The motor mount is fixed to the central axis of the exhaust pipe by the guide vanes. A drive motor is installed inside the motor mount, and a front fan blade is mounted on the main shaft of the drive motor. The front fan blade rotates inside the exhaust pipe, drawing in air from the air inlet and expelling it from the rear of the exhaust pipe. The beneficial effects of this invention are: the front fan blade is a mixed-flow fan blade, and combined with an optimized number of blades and a reasonable design of the inclination angle, curvature, and angle of attack of the inner and outer edges of the blades, the blades can efficiently perform work on the air during rotation, generating excellent airflow characteristics that balance large air volume and high air pressure.

This utility model relates to the field of high-pressure reactor technology and discloses a glass high-pressure reactor with an inlet / outlet rack structure. The reactor includes a reactor body arranged longitudinally. An inlet pipe is connected to the outer wall of the upper end of the reactor body. A valve is installed inside the inlet pipe. An inlet auxiliary component is located on the upper left side of the inlet pipe. An outlet pipe is connected to the bottom surface of the reactor body. A valve is installed inside the outlet pipe. An outlet auxiliary component is located below the outlet pipe. A motor is installed on the top surface of the reactor body. The output end of the motor movably passes through the top surface of the reactor body and extends into the interior of the reactor body. A stirring shaft is fixedly installed on the output end of the motor. This glass high-pressure reactor with an inlet / outlet rack structure achieves stable material introduction and precise guidance through the combination of a feeding plate, a guide plate, and a partition, preventing material from falling and improving feeding efficiency and accuracy. The discharge plate receives the material discharged from the outlet pipe, facilitating centralized collection and transportation, making the discharge process more convenient.
