[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] The utility model provides a technical solution: Figure 1 , Figure 2 and Figure 3 As shown, in the present embodiment, a protective structure for a woodworking band saw machine comprises a band saw machine body 1, characterized in that: a saw blade 2 is installed inside the band saw machine body 1, a protective component 3 is installed on the band saw machine body 1, the protective component 3 comprises a limiting groove 301 provided on the inner wall of one side of the band saw machine body 1, a screw rod 302 is rotatably connected to the top and bottom inner walls of the limiting groove 301, the screw rod 302 is externally threadedly connected to two connecting rods 303, the two connecting rods 303 are both slidably connected in the limiting groove 301, one end of the two connecting rods 303 is fixedly connected to the same protective frame 304, and the protective frame 304 surrounds the outside of the saw blade 2.

[0024] A driving rod 307 is rotatably connected inside the band saw machine body 1. One end of the driving rod 307 is located in the limiting groove 301 and the other end extends out of the band saw machine body 1. A bevel gear 1 305 is centrally sleeved on the lead screw 302. A bevel gear 2 306 meshing with the bevel gear 1 305 is coaxially fixed to one end of the driving rod 307.

[0025] The driving rod 307 is rotated to expose one end of the band saw machine body 1, and the driving rod 307 drives the bevel gear 2 306 to rotate. The bevel gear 2 306 drives the bevel gear 1 305 to rotate through meshing. The bevel gear 1 305 drives the screw rod 302 to rotate in the limiting groove 301. The two connecting rods 303 restricted by the limiting groove 301 will move upward along the screw rod 302 under the drive of the screw rod 302. The protective frame 304 connected to the two connecting rods 303 moves synchronously with the two, so that part of the saw blade 2 is exposed to the outside.

[0026] like Figure 2 and Figure 4 As shown, a material belt assembly 4 is installed at one end of the saw blade 2, and the material belt assembly 4 includes a limit frame 1 401 fixedly connected to the top outer wall of the band saw machine body 1, a limit frame 2 402 is slidably connected to the bottom inner wall of the limit frame 1 401, a limit frame 3 403 is slidably connected to the bottom inner wall of the limit frame 2 402, and a material belt rack 404 is slidably connected to the bottom inner wall of the limit frame 3 403.

[0027] A plurality of screw rods 405 are threadedly connected to the top of the material rack 404 , and a fixing block 406 is rotatably connected to one end of the bottom of the plurality of screw rods 405 . A handle 407 is fixedly connected to the outer wall of one end of the material rack 404 .

[0028] Place the wooden board in the material rack 404, and then rotate the screw 405 at the top of the material rack 404. The screw 405 rotates and moves from top to bottom until the fixed block 406 at its bottom presses on the top of the wooden board, and the wooden board can be fixed. Finally, the material rack 404 is pushed to slide in the limit frame three 403 through the handle 407. When the material rack 404 moves to the end, it will drive the limit frame three 403 to slide in the limit frame two 402. Similarly, after moving to the end of the limit frame two 402, the limit frame three 403 will cause the limit frame two 402 to slide in the limit frame one 401, thereby being able to adapt to the processing of wooden boards of different lengths, and the user does not need to get close to the saw blade 2 to complete the processing.

[0031] The utility model provides a protective structure for a woodworking band saw machine, and the specific working principle is as follows:

[0032] When the device is working, the height of the protection frame 304 is first adjusted through the protection component 3 according to the thickness of the wood to be cut, and the driving rod 307 is rotated to expose one end of the band saw machine body 1. The driving rod 307 drives the bevel gear 2 306 to rotate, and the bevel gear 2 306 drives the bevel gear 1 305 to rotate through meshing. The bevel gear 1 305 drives the screw rod 302 to rotate in the limiting groove 301. The two connecting rods 303 restricted by the limiting groove 301 will move upward along the screw rod 302 under the drive of the screw rod 302. The protection frame 304 connected with the two connecting rods 303 moves synchronously with the two, so that part of the saw blade 2 is exposed to the outside world, and then the wooden board is placed on the belt rack 4. 04, then rotate the screw 405 at the top of the material rack 404, the screw 405 rotates and moves from top to bottom until the fixed block 406 at the bottom is pressed on the top of the wooden board, and the wooden board can be fixed, and finally the material rack 404 is pushed to slide in the limit frame three 403 through the handle 407. When the material rack 404 moves to the end, it will drive the limit frame three 403 to slide in the limit frame two 402. Similarly, after moving to the end of the limit frame two 402, the limit frame three 403 will limit the frame two 402 to slide in the limit frame one 401, so as to adapt to the processing of wooden boards of different lengths, and the user does not need to get close to the saw blade 2 to complete the processing.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
