The embodiment of the application discloses a plate cutting machine. Referring to fig. 1, the plate cutting machine includes a frame 1, a table 2, a master saw wheel 3, a slave saw wheel 4, a band saw blade 5, and a drive mechanism 6. In this embodiment, the frame 1 includes an upper frame 11, a lower frame 12, and a connecting frame 13 connected to the sides of the upper frame 11 and the lower frame 12. The workbench 2 is horizontally arranged on the upper part of the lower machine base 12, and a working space for accommodating wood is arranged between the workbench 2 and the upper machine base 11.
The main saw wheel 3 is rotationally connected with the lower machine seat 12, the driving mechanism 6 is arranged at the lower machine seat 12, and the driving end of the driving mechanism 6 is connected with the main saw wheel 3 to drive the main saw wheel 3 to rotate. In this embodiment, the drive mechanism 6 is a variable speed motor so that the rotational rate of the main saw wheel 3 can be adjusted. The slave saw wheel 4 is rotationally connected with the upper stand 11, and the band saw blade 5 is sleeved on the peripheries of the master saw wheel 3 and the slave saw wheel 4; at the same time, the work table 2 is provided with a space for the band saw blade 5 to pass through. The band saw blade 5 is an annular steel belt with one side toothed, so that the driving mechanism 6 can drive the band saw blade 5 to reciprocate through the main saw wheel 3 and the auxiliary saw wheel 4, and the band saw blade 5 moving at a high speed is used for cutting wood.
When the band saw blade 5 cuts wood, the band saw blade 5 located between the slave saw wheel 4 and the wood is easily deformed by vibration. In order to provide sufficient space for the operator, the saw wheel 4 is usually provided with a large height from the work piece, so that the saw blade 5 between the saw wheel 4 and the wood has a large length, and the vibration amplitude of the saw blade 5 is large to affect the flatness of the cut surface of the wood.
Therefore, the plate cutting machine further includes a limiting mechanism 7, and the limiting mechanism 7 is used for reducing the vibration deformation amplitude of the band saw blade 5.
Referring to fig. 1 to 3, the limit mechanism 7 includes an adjustment lever 71, a bolt 72, a fixing member 73, and a plurality of rollers 74. Referring to fig. 1, a fixing member 73 is fixedly connected to the bottom of the adjustment lever 71, and a roller 74 is provided on the fixing member 73 for abutting against the band saw blade 5. The upper housing 11 is provided with a through hole penetrated by the adjusting rod 71, so that the adjusting rod 71 is slidably connected with the upper housing 11. The bolt 72 is screwed through the side wall of the through hole and then abuts against the adjusting rod 71, so that the position of the adjusting rod 71 is fixed.
The worker can adjust the position of the fixing piece 73 according to the thickness of the wood to be sawn, and when the thickness of the wood is large, the worker can slide the adjusting rod 71 upwards so that the roller 74 on the fixing piece 73 is abutted against the upper band saw blade 5; so that the rollers 74 restrain the band saw blade 5, reducing the vibration deformation of the band saw blade 5 and also reducing the influence of the fixing member 73 on the wood to be cut. When the thickness of the wood is small, the worker slides the adjusting rod 71 downwards to enable the roller 74 on the fixing piece 73 to be abutted against the lower band saw blade 5, and the roller 74 is used for restraining the band saw blade 5, so that vibration deformation of the band saw blade 5 is further reduced.
Referring to fig. 2 and 3, the fixing member 73 is provided with a groove 8 through which the band saw blade 5 is inserted, two rollers 74 are provided on side walls of both sides of the groove 8, and the rollers 74 are abutted against the band saw blade 5, thereby restraining the vibration deformation amplitude of the band saw blade 5. In order to enable the roller 74 to tightly abut against the band saw blade 5, the roller 74 is connected to the fixing member 73 through the adjusting member 9. In this embodiment, the adjusting member 9 is threadedly coupled to the fixed member 73, so that a worker can adjust the degree of abutment of the roller 74 with the saw blade 5 by rotating the adjusting member 9.
Meanwhile, in the vertical direction, the rollers 74 provided on both sides of the band saw blade 5 are arranged to be staggered up and down with each other. So that the rollers 74 on both sides can restrict the vibration deformation of the band saw blade 5 at different heights to further improve the flatness of the cut surface of the wood.
Referring to fig. 3, the outer periphery of the roller 74 is further sleeved with a flexible member 10, and the flexible member 10 is abutted against the band saw blade 5; thereby reducing wear of the band saw blade 5 by the rigid counter roller 74 and reducing the frequency of replacement of the band saw blade 5.
Example 2
This embodiment 2 differs from embodiment 1 in that:
referring to fig. 4, the present embodiment 2 differs from embodiment 1 in that:
the adjusting member 9 for adjusting the position of the roller 74 includes a connecting rod 14 and a spring 15. One end of the connecting rod 14 is rotationally connected with the fixing piece 73, and the other end of the connecting rod 14 is connected with the roller 74; a spring 15 is arranged between the connecting rod 14 and the connecting rod 14. Therefore, the roller 74 positioned at the tail end of the connecting rod 14 is always abutted against the band saw blade 5, and the roller 74 has good restraining effect on the band saw blade 5.
Example 3
This embodiment 3 differs from embodiment 1 in that:
referring to fig. 5, the width of the flexible member 10 on the side away from the roller 74 is smaller than the width of the flexible member 10 on the side abutting against the roller 74. When the band saw blade 5 cuts a material having a large hardness, such as a wood central portion healed tumor, the band saw blade 5 is liable to undergo a large vibration deformation. When the vibration deformed band saw blade 5 presses the flexible member 10, the flexible member 10 may be slightly deformed at a side away from the roller 74, thereby buffering movement of the band saw blade 5 to reduce internal stress of the band saw blade 5 and damage of the band saw blade 5.
The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
