Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, and more specifically to a log cutting device. Background Technology

[0002] A log is a piece of wood cut into a certain length according to standard or special specifications for size, shape, and quality. This piece of wood is called a log. In order to facilitate subsequent processing of logs, logs need to be cut and processed according to requirements.

[0003] A search revealed an existing patent (publication number: CN220661197U) that discloses a log cutting device. During use, a hydraulic telescopic rod drives a U-shaped box to move up and down, adjustable according to the log's height. A second motor is activated, its output rotating to drive a bidirectional threaded rod, which in turn moves two C-shaped clamps synchronously with the movable sleeve, adjustable according to the log's size, lifting the log away from the ground. A first motor is then activated, its forward rotation driving the threaded rod forward, which in turn moves an L-shaped moving column away from the first motor, thus moving the clamped log. The log is then placed on the cutting table according to the cutting position. After cutting, the clamping device picks up the cut log and moves it to the end of the cutting table to complete the unloading. The first motor is then activated again, its reverse rotation driving the L-shaped moving column closer to the first motor, returning it to the loading end. This effectively solves the problem of worker workload in loading / unloading and manually adjusting the cutting angle. However, in the process of realizing this utility model, the inventors discovered the following problems with the existing technology: The above-mentioned log cutting device uses a C-shaped clamp to clamp and feed the log. After the cutting action is completed, the C-shaped clamp is lowered to a position close to the ground, and then the C-shaped clamp is used again to clamp, lift and feed the log. In this process, it takes a lot of time to clamp and lift the log with the C-shaped clamp, which will reduce the efficiency of cutting and processing and make it difficult to meet the needs of continuous and efficient cutting and processing.

[0004] In view of this, the present invention proposes a log cutting device with rapid feeding to solve this problem. Utility Model Content
