[0032] See also Figure 1-7 The plywood band saw shown in the figure comprises a base 1, characterized in that a cutting device 2, a column 3 and a cutting table device 4 are provided on the base 1, the column 3 is fixedly arranged on the base 1, and the cutting table device 4 is arranged on the column 3. The base 1 is used to be installed on a flat ground or an equipment rack, and the column 3 is mainly used to install the cutting device 2 and the cutting table device 4. The cutting device 2 is mainly used for cutting plywood, and the cutting table device 4 is used for placing and limiting the plywood to be cut.

[0033] The cutting device 2 includes an upper runner 2a, a lower runner 2b, a band saw blade 2c, a driving motor 2d and a tension adjusting assembly 2e. The upper runner 2a is arranged at the upper part of the column 3 through the tension adjusting assembly 2e, the lower runner 2b is arranged at the lower part of the column 3, the band saw blade 2c is sleeved on the upper runner 2a and the lower runner 2b, the lower runner 2b is connected to the rotating shaft of the driving motor 2d through a first connecting shaft 2f, and the first connecting shaft 2f is connected to the column 3 through a bearing. A rectangular cavity 2g and a waist-shaped through hole 2h are also provided on the column 3, and the waist-shaped through hole 2h communicates with the rectangular cavity 2g. When cutting plywood, the driving motor 2d rotates to drive the lower runner 2b to rotate, and at the same time drives the upper runner 2a to rotate together through the band saw blade 2c, so that the band saw blade 2c can continuously operate to cut the plywood through the saw teeth on the band saw blade 2c. After long-term use, the band saw blade 2c will be stretched, so the tension adjusting assembly 2e is provided to adjust the tension of the band saw blade 2c to ensure its normal operation.

[0034] The tension adjusting assembly 2e includes a handwheel 2ea, a connecting block 2eb, a rotating rod 2ec, a sliding plate 2ed, a hand-tightening bolt 2ee and an anti-slip gasket 2ef. The connecting block 2eb is fixedly arranged at the top of the column 3. The rotating rod 2ec is connected to the connecting block 2eb through a bearing, and one end of the rotating rod 2ec is connected to the handwheel 2ea, and the other end is connected to the sliding plate 2ed through a threaded fit with a threaded hole. The sliding plate 2ed is arranged in the rectangular cavity 2g and can slide up and down in the rectangular cavity 2g. The upper runner 2a is connected to the sliding plate 2ed through a second connecting shaft 2j. One end of the second connecting shaft 2j is connected to the upper runner 2a through a bearing, and the other end is connected to the sliding plate 2ed. The anti-slip gasket 2ef is sleeved on the threaded part of the hand-tightening bolt 2ee.

[0035] When adjusting the tension adjusting device 2d, the operator rotates the handwheel 2ea to drive the rotating rod 2ec to rotate. The end of the rotating rod 2ec, that is, the end close to the sliding plate 2ed, is provided with a thread and is connected to the sliding plate 2ed through a threaded connection with a threaded hole. During the rotation of the rotating rod 2ec, the depth of its penetration into the sliding plate 2ed also changes. And at this time, the position of the rotating rod 2ec relative to the column 2 does not change, so the rotating rod 2ec can pull the sliding plate 2ed to move up and down. At this time, the upper runner 2a connected to the sliding plate 2ed through the first connecting shaft 2f also moves up and down, thereby realizing the adjustment of the tension of the band saw blade 2c.

[0036] The cutting table device 4 includes a cutting bottom plate 4a, a set of first linear guide pairs 4b, a set of second linear guide pairs 4c, a third linear guide pair 4d and a fourth linear guide pair 4e. The set of first linear guide pairs 4b and the set of second linear guide pairs 4c are symmetrically arranged on the cutting bottom plate 4a. The two ends of the third linear guide pair 4d are respectively connected to the sliders on the set of first linear guide pairs 4b, and the two ends of the fourth linear guide pair 4e are respectively connected to the sliders on the set of second linear guide pairs 4c. There are multiple sliders on the third linear guide pair 4d and the fourth linear guide pair 4e.

[0037] The first linear guide pair 4b provided on the cutting table device 4 can drive the third linear guide pair 4d to move in the direction of the slider of the first linear guide pair 4b. Similarly, the second linear guide pair 4c can drive the fourth linear guide pair 4e to move in the movement direction of the slider of the second linear guide pair 4d, so as to achieve the purpose of clamping the two sides of the plywood to be cut. The stability of the plywood during cutting is improved, and the cutting quality is improved. Through holes are provided on the guide rails of the third linear guide pair 4d and the fourth linear guide pair 4e, and the through holes are set in the form of threaded holes. Locking screws are provided in the through holes to fix the positions of the third linear guide pair 4d and the fourth linear guide pair 4e. When locking, rotate the locking screw and make the end of the locking lock tightly against the cutting bottom plate 4a, so that the third linear guide pair 4d and the fourth linear guide pair 4e can be fixed.

[0038] Specifically, contact blocks 4f made of rubber material are also provided on the sliders of the third linear guide pair 4d and the fourth linear guide pair 4e.

[0039] In this implementation scheme, the main purpose of setting the contact blocks 4f made of rubber material is to protect the sides of the plywood from being damaged due to excessive clamping force.

[0040] Specifically, a protective cover 5 is also provided on one integrated side of the column 3 by means of hinge connection.

[0041] In this implementation scheme, the protective cover 5 is connected to the column 3 by a hinge for easy opening and closing, and the other side of the protective cover 5 is connected to the column 3 by a buckle, so as to protect the device provided on the column 3 and ensure the safety of the equipment during operation.

[0042] Specifically, it also includes an adjustment plate 6 and a group of abutment members 7, one of which is fixedly arranged at the bottom end of the adjustment plate 6, and the other is arranged on the column 3. The adjustment plate 6 is provided with an adjustment waist-shaped hole 8, a butterfly nut 9 and a fixing bolt 10, and the fixing bolt 10 passes through the column 3 and the adjustment waist-shaped hole 8 and is connected with the butterfly nut 9 to fix the adjustment plate 6 on the column 3. The abutment member 7 includes a fixing block 7a, a connecting roller 7b, a notch 7c, a first bearing 7d and a group of bolt rolling bearings 7e, the connecting roller 7b is arranged on the upper part of the fixing block 7a and passes through the notch 7c, the first bearing 7d is arranged in the notch 7c and its inner ring is connected with the connecting roller 7b, and a group of bolt rolling bearings 7e are arranged on the outer side of the fixing block 7a and symmetrically arranged on both sides of the notch 7c.

[0043] In this embodiment, the adjustment plate 6 is designed to be adjustable in position up and down, so that the staff can make adjustments according to different working conditions.

[0044] The designed abutment 7 is used to reduce the vibration of the band saw blade 2c during high-speed operation, and prevent excessive vibration from causing poor cutting quality. Specifically, the back side of the band saw blade 2c, that is, the other side of the sawtooth side, contacts the outer ring of the first bearing 7d, and the two side surfaces of the sawtooth bar 2c are arranged between the two bolt rolling bearings 7e, and the distance between the two bolt rolling bearings 7e is adaptively set. When the sawtooth bar 2c is working, its vibration can be limited by the two bolt rolling bearings 7e without excessive vibration, thereby ensuring the stability of cutting.

[0045] Working principle:

[0046] When cutting the plywood, the staff first puts one end of the plywood on the cutting base plate 4a, and the plywood fits the cutting base plate 4a, and then adjusts the positions of the third linear guide pair 4d and the fourth linear guide pair 4e according to actual needs. After the adjustment, the third linear guide pair 4d and the fourth linear guide pair 4e are fixed by locking screws to prevent position deviation during the cutting process. Then the staff pushes the plywood, and the band saw blade 2c on the cutting device 2 cuts the plywood.
