Description

Technical Field

[0001] The present application relates to the technical field of sawing machines, and in particular to a saw blade cooling structure. Background Art

[0002] A sawing machine is a device that uses a rotating saw blade to cut workpieces. Usually, the material is loaded by a worker and mechanically transported to the high-speed rotating saw blade for cutting. After cutting, the material is unloaded mechanically.

[0003] However, during the rotating cutting process, the saw blade surface will rub against the workpiece, which will generate a large amount of frictional heat energy on the saw blade. The increased temperature of the saw blade will cause the saw blade to lose its original hardness and toughness, and the stability and cutting performance of the saw blade will decrease, thus affecting the normal use of the saw blade.

[0018] Preferably, the driving assembly includes a driving motor fixedly mounted on the frame, and a connecting seat fixedly connected to a rotating shaft of the driving motor, and the connecting seat is fixedly connected to the rotating joint.

[0019] By adopting the above technical solution, the drive motor is electrically connected to the external power supply, the drive motor is started, the shaft of the drive motor rotates, driving the connecting seat to rotate, the rotation of the connecting seat drives the inner ring of the rotating joint to rotate, and the rotation of the rotating joint drives the rotating shaft to rotate, thereby realizing the rotation of the rotating shaft.

[0020] Preferably, a pressing plate is installed on the rotating shaft, and the pressing plate is located at one end of the rotating shaft away from the frame. A locking seat for pressing the pressing plate is threadedly connected to the rotating shaft.

[0021] By adopting the above technical solution, the pressing plate is arranged to press the shaft sleeve and the saw blade installed on the rotating shaft, and the pressing plate is locked by the locking seat, thereby achieving the fixation of the shaft sleeve and the saw blade.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. Through the arrangement of the water spray assembly, the driving assembly, the saw blade, and the water supply pipe, when the driving assembly drives the saw blade to rotate, the water spray assembly sprays water on the saw blade, cools the saw blade when the saw blade is cutting, and facilitates the saw blade to continue working;

[0024] 2. The water spraying port is set to be gradually contracted, which makes it easier for water to enter the water spraying port and spray out.

Each water outlet 6 is in the shape of a long groove. A water spray port 7 is provided on the shaft sleeve 22, and the width of the water spray port 7 gradually decreases in the direction away from the rotating shaft 21, so that the end of the water spray port 7 close to the rotating shaft 21 is a bowl-shaped groove, and the end of the water spray port 7 away from the rotating shaft 21 is a slender groove. The water spray port 7 is on the shaft sleeve 22. There are multiple water spouts 7. In this embodiment, there are four water spouts 7. The four water spouts 7 are evenly spaced along the circumference of the shaft sleeve 22. A saw blade 3 is also installed on the rotating shaft 21. One saw blade 3 is located between the two shaft sleeves 22. The water spouts 7 on the two shaft sleeves 22 are both set to fit the saw blade 3. In order to increase the sealing performance during use, a gasket is usually added to the surface of the shaft sleeve 22 that fits the saw blade 3 and the rotating shaft 21. When in use, water enters from the inside of the rotating shaft 21 and flows out from the outlet of the rotating shaft 21. Water is sprayed out from the water outlet 6 into the cavity formed between the rotating shaft 21 and the shaft sleeve 22, and then sprayed out from the water outlet 7 on the shaft sleeve 22.
