Description

Technical Field

[0001] This utility model relates to the field of horizontal band saw adjustment technology, specifically a saw band adjustment structure for a horizontal band saw. Background Technology

[0002] A horizontal band saw is a cutting device that cuts through a continuously circulating saw band. It has the advantages of high efficiency, high precision and wide range of applications. It is mainly used for cutting various materials, especially in metal processing and wood processing.

[0003] Existing technology, patent application number CN202322893126.3, discloses a horizontal band saw blade adjustment structure, belonging to the field of band saw technology. It addresses the problem that in existing band saws, during adjustment and use, the support rods slide with the saw blade to one side of the saw blade, affecting the cutting quality, because both support rods slide with the adjustment groove. The proposed structure includes a saw blade worktable with a groove at its top. A bidirectional screw is rotatably mounted within the groove. Movable blocks are threaded onto the external threaded surfaces of both sides of the bidirectional screw, and an electric telescopic rod is fixedly mounted on the top of each movable block. This invention utilizes a bidirectional screw, movable blocks, an electric telescopic rod, and a fixed... The design of components such as the fixed block, support column, rotating wheel, and motor allows for stable adjustment of the saw band tension, improving its performance. The use of limit rings and bolts facilitates the positioning of the saw band and also allows for easy disassembly. However, during use, the saw band's orientation is fixed, limiting cutting to the horizontal direction. Different materials require different cutting methods, making this inconvenient for daily use. Furthermore, the saw band needs to be positioned during operation, but most horizontal band saws' positioning devices cannot be adjusted according to the saw band thickness, further complicating daily use. To address these issues, the inventor proposes a saw band adjustment structure for a horizontal band saw. Utility Model Content

[0021] Movable seats 24 are slidably mounted on both sides of the upper surface of the two mounting plates 2. A connecting strip 25 is rotatably mounted inside the movable seat 24, and the end of the connecting strip 25 away from the movable seat 24 is rotatably connected to the rotating plate 21 to drive the rotating plate 21 to rotate. In use, the movement of the movable seat 24 drives the connecting strip 25 to swing, and the swing of the connecting strip 25 drives the rotating plate 21 to rotate.

[0022] By adopting the above technical solution, the movable seat 24 can drive the rotating plate 21 to rotate.

[0023] Both sides of the two mounting plates 2 are rotatably mounted with drive screws 26, and the drive screws 26 are threadedly connected to movable seats 24, which are used to drive the movable seats 24 to move. In use, the movable seats 24 are moved by the rotation of the drive screws 26.

[0024] By adopting the above technical solution, the drive screw 26 can drive the moving seat 24 to move.

[0026] By adopting the above technical solution, the crossbar 28 can drive the drive screw 26 to rotate.

[0027] Support frames 4 are fixedly installed on the side of the upper surface of the two mounting plates 2 away from the rotating plate 21, for mounting transmission rods 41. Transmission rods 41 are rotatably installed in the top of the two support frames 4, and the transmission rod 41 on the left side is slidably inserted into the transmission rod 41 on the right side. The transmission rod 41 on the same side and the crossbar 28 are driven by a synchronous pulley and a synchronous belt. A second motor 42 is fixedly installed on the side of the support frame 4 on the left side, and the output shaft of the second motor 42 near the support frame 4 is fixedly connected to the transmission rod 41 to drive the crossbar 28 to rotate.

[0030] By adopting the above technical solution, the long screw 37 can drive the limiting roller 36 to move.

[0031] Two rotating bars 34 are fixedly mounted with worm gears 38 on the outer surface of one end, and the worm gears 38 are rotatably disposed inside the mounting base 32. A worm 39 is rotatably mounted inside one side of the mounting base 32, and the worm 39 meshes with the worm gears 38 to drive the rotating bars 34 to rotate. In use, rotating the worm 39 drives the worm gears 38 to rotate, and the rotation of the worm gears 38 drives the rotating bars 34 to rotate.

[0032] By adopting the above technical solution, the worm gear 39 can drive the rotating bar 34 to rotate.

[0034] By adopting the above technical solution, the adjusting screw 33 can drive the mounting base 32 to move.

[0035] Working principle: First, when the orientation of the saw blade needs to be adjusted, the saw blade is removed, and the second motor 42 is turned on to drive the transmission rod 41 to rotate. The rotation of the transmission rod 41 drives the crossbar 28 to rotate, which in turn drives the second bevel gear 29 to rotate. The rotation of the second bevel gear 29 drives the first bevel gear 27 to rotate, which in turn drives the drive screw 26 to rotate. The rotation of the drive screw 26 drives the moving seat 24 to move, which in turn drives the connecting bar 25 to swing. The swing of the connecting bar 25 drives the rotating plate 21 to rotate, thus adjusting the angle of the rotating plate 21.

[0036] Secondly, the angles of the No. 1 motor 22 and the drive wheel 23 are adjusted by rotating the rotating plate 21, which makes it convenient to adjust the angle of the saw blade.

[0037] Then, rotating the adjusting screw 33 drives the mounting base 32 to move. The movement of the mounting base 32 drives the rotating bar 34 to move, adjusting the position of the rotating bar 34. Rotating the worm 39 drives the worm wheel 38 to rotate, and the rotation of the worm wheel 38 drives the rotating bar 34 to rotate, adjusting the angle of the rotating bar 34, thereby limiting the saw blade and changing the orientation of the saw blade so that the saw blade is downward.

[0038] Finally, install the saw blade and make the fixed roller 351 contact the outer surface of the saw blade. Then rotate the rotating long screw 37 to drive the limiting roller 36 to move, so that the limiting roller 36 contacts the other side of the saw blade to limit the saw blade.

[0039] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
