[0002] In the poetry of the Tang and Song dynasties, poets and lyricists used "firecrackers" as the subject to record New Year customs, write about the excitement of the festival, express the joy of welcoming the new year, express the longing for relatives, express the feelings of family and country, and express the emotion of life. The existing firecrackers need to be packaged in a firecracker-binding machine when they are processed. When the existing firecracker-binding machines on the market are unloading and packaging firecrackers, most of the firecrackers are directly dumped into the unloading hopper and unloaded by their own gravity. However, during the use of the firecracker-binding machine, due to reasons such as the hard and bent lead wire or the firecrackers being out of round, it is easy for the firecrackers to fall over or scatter during the unloading process, which may cause the firecracker-binding machine to jam. When the machine jams, the machine can only be restarted by manually clearing the obstacles, which seriously reduces the working efficiency. For this reason, it is necessary to provide a safe unloading device for a firecracker-binding machine to solve the above problems. Utility Model Content
