Description

Technical Field

[0001] This utility model belongs to the field of drum cutting technology, and relates to a drum body cutting mechanism for wooden drums. Background Technology

[0002] A drum is a percussion instrument consisting of a sturdy, generally cylindrical drum body covered with a taut membrane on one or both sides. Drums are struck by hand or with a drumstick to produce sound. To meet different usage requirements, the sound of a percussion drum needs to be slit into appropriate sizes. For example, a slitting mechanism of a slitting machine disclosed in patent application number CN202421191407.2 includes an intermediate shaft. The top and bottom of the outer wall of the intermediate shaft have graduated grooves extending laterally. Multiple sliding seats are sleeved on the outer wall of the intermediate shaft. The sliding seats are tubular and slidably fitted with the intermediate shaft. A cutter, which is disc-shaped, is fixedly sleeved on the left end of the outer wall of the sliding seat. Locking bolts are threaded to the top and bottom of the sliding seats. Two locking bolts are located on the right side of the cutter and abut against the outer wall of the intermediate shaft. Plugs are fixedly connected to the upper parts of both ends of the intermediate shaft. Connecting shafts are located at both ends of the intermediate shaft, and slots are formed at the top of the opposite ends of the two connecting shafts.

[0003] The existing cutting mechanism has the following drawbacks: when cutting the drum body, only a single drum body is installed in the clamping part, and the drum body cannot move longitudinally relative to the saw blade. To address this, we designed a wooden percussion drum body cutting mechanism. Summary of the Invention
