Description

Technical Field

[0001] This utility model relates to the field of bone sawing machine technology, specifically a horizontal bone sawing machine with adjustable length. Background Technology

[0002] The bone saw, consisting of a frame, motor, circular saw, horizontal table, and electrical control panel, is suitable for processing various small and medium-sized animal bones, frozen meat, fish bones, frozen fish, and ice blocks. It is used for cutting small pieces of frozen meat and ribs. It is widely applicable in large-scale centralized food processing plants, slaughterhouses, meat processing plants, and other similar locations.

[0003] An existing Chinese utility model patent discloses a general-purpose clamping bone saw with a simple structure, convenient use, and a hoisting clamp. It includes a worktable, a frame, a saw blade, an adjusting plate, and an aggregate clamp. The adjusting plate is slidably mounted on the worktable. The frame is mounted on the worktable, and the saw blade is wound between the frame and the worktable. A transmission mechanism for driving the saw blade to rotate is provided within the worktable. A sliding seat is provided at the front end of the frame. The aggregate clamp is hoisted by a connecting rod and slidably mounted below the sliding seat. The aggregate clamp includes a connecting seat, a clamping plate, and a threaded cone. The connecting seat is fixedly connected to the connecting plate. Two grooves are formed inward along the length direction at both ends of the connecting seat. One end of the clamping plate is slidably installed in the groove, and the other end of the clamping plate has an extension extending in the width direction of the connecting seat. The threaded cone is threaded through the extension.

[0004] Most existing bone saws are vertical structures, and the cutting width is controlled by adjusting the distance between the baffle on one side of the saw blade and the saw blade. This method may affect the cutting width because the bone does not contact the baffle during cutting. At the same time, the saw blade is in a vertical position and exposed, which is less safe.
