DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figures 1 to 6 As shown, the utility model provides a bidirectional cutting machine which is convenient for replacing saw blades, comprising a cutting plate 1, a fixed plate 2 is fixedly installed at the front end in the middle of the top surface of the cutting plate 1, a slider 3 is opened inside the fixed plate 2, a slide groove 4 is slidably connected in the front and rear grooves of the slider 3, a threaded column 5 is engaged inside the slide groove 4, a fixed shaft 6 is fixedly installed at the left end of the slide groove 4, the outer end of the fixed shaft 6 is rotatably connected to a turntable 7, a support bar 8 is inserted at the left end of the fixed shaft 6, a cleaning brush 9 is fixedly installed at the other end of the support bar 8, a fixed door 11 is hinged at the left end of the fixed plate 2, a cabinet 19 is fixedly installed at the bottom of the cutting plate 1, a motor 20 is fixedly installed inside the right side of the cabinet 19, a turntable 2 22 is fixedly installed at the output end of the motor 20, and a saw blade 10 is transmission-connected between the turntable 7 and the turntable 2 22.

[0022] First, remove the support bar 8 and the cleaning brush 9 fixed on the support bar 8, and then rotate the threaded column 5. The rotating threaded column 5 transmits force to the slide 4. The transmitted force causes the slide 4 to slowly move downward. The downward slide 4 drives the fixed shaft 6 on the left and the turntable 1 7 slidably connected to the fixed shaft 6 to slowly descend until the saw blade 10 can be taken out. Then take out the saw blade 10, and then place the new saw blade 10 between the turntable 1 7 and the turntable 2 22. Rotate the threaded column 5 in the opposite direction until the saw blade 10 is fixed, thereby achieving the effect of facilitating the replacement of the saw blade 10.

[0023] Among them, connecting blocks 12 are fixedly installed on the left and right ends of the rear side of the cutting plate 1, and a sliding rod 13 is fixedly installed between the connecting blocks 12. The outer end of the sliding rod 13 is slidably connected to a sliding block 14, and the front end of the sliding block 14 is fixedly installed with a push plate 15. The right bottom end of the fixed plate 2 is fixedly installed with a fixed block 16, and the internal movably connected to the fixed block 16 is a fixed rod 17, and the rear end of the fixed rod 17 is fixedly installed with a push plate 2 18.

[0024] By turning the bolt on the right side of the fixing block 16, the fixing rod 17 fixed inside the fixing block 16 is loosened, and the push plate 2 18 is adjusted to a suitable cutting position. The bolt is turned to fix the fixing block 16 to fix the fixing rod 17, and the fixing rod 17 fixes the push plate 2 18 so that the push plate 2 18 cannot move. Then, the object to be cut is placed in front of the push plate around the push plate 15, and the handle on the push plate 15 is held and pushed until the object to be cut is cut, thereby achieving the effect of not hurting the hands during cutting.

[0025] A waste trough 21 is placed inside the left side of the cabinet 19 , and the bottom of the threaded column 5 is rotatably connected to the bottom of the slider 3 .

[0026] The waste trough 21 placed inside the left side of the cabinet 19 can effectively collect residues and debris. The bottom of the threaded column 5 is rotatably connected to the bottom of the slider 3 to fix the threaded column 5 and make it more stable.

[0027] Among them, the shape of the push plate 15 is U-shaped, the shape of the push plate 2 18 is L-shaped, the outer circles of the turntable 1 7 and the turntable 2 22 are both provided with grooves, and the left and right ends of the fixed shaft 6 are equipped with protrusions.

[0028] The U-shaped push plate 15 allows bidirectional cutting, and the grooves on the outer sides of the turntable 1 7 and the turntable 2 22 can effectively prevent the saw blade 10 from escaping. The protrusions installed on the left and right sides of the fixed shaft 6 are used to fix the turntable 1 7.

[0029] Among them, a bolt is fixedly installed on the right side of the fixing block 16, and the fixing rod 17 is at the left end of the bolt and contacts it. The middle part of the push plate 15 and the front end of the push plate 2 18 are supported by support blocks.

[0030] The bolt installed on the right side of the fixing block 16 fixes the fixing rod 17 to prevent it from moving, and the support blocks of the push plate 15 and the push plate 2 18 prevent the push plates from bending and deforming.

[0031] Two saw slots are formed on the left end of the cutting plate 1 , and the top end of the cleaning brush 9 is inclined toward the saw blade 10 and in contact with the saw blade 10 .

[0032] The saw slot opened at the left end of the cutting plate 1 is used for replacing the saw blade, and the top of the cleaning brush 9 contacts the saw blade 10 to facilitate cleaning of the residues and debris remaining on the saw blade 10.

[0033] The working principle and usage process of the present invention are as follows: when replacing the saw blade, first hold the handle on the fixed door 11 to pull open the fixed door 11, then open the door on the left side of the cabinet 19, and then remove the support bar 8 plugged into the left side of the fixed shaft 6 and the cleaning brush 9 fixed on the support bar 8, and then rotate the threaded column 5. The rotating threaded column 5 transmits the force to the slide 4 through the thread below. The force transmitted by the thread inside the slide 4 slowly moves downward through the grooves opened in the front and back of the slider 3. The slowly downward slide 4 drives the fixed shaft 6 installed on the left and the turntable 1 7 connected to the fixed shaft 6 to rotate downward together until the saw blade 10 can be taken out, and then the saw blade 10 is taken out through the two gaps opened in the cutting board 1. After taking it out, the saw blade 10 to be used is put in along the two gaps and stuck between the upper and lower turntables 1 7 and turntable 2 22, and the threaded column 5 is rotated in the opposite direction until the saw blade 10 is fixed.

[0034] Before starting to cut, first turn the bolt on the right side of the fixed block 16 to loosen the fixed rod 17 fixed inside the fixed block 16, then move the push plate 2 18 back and forth to a suitable position and distance, and then turn the bolt on the right side of the fixed block 16 to squeeze and fix the fixed rod 17 to prevent it from moving inside the fixed block 16. When cutting, place the object to be cut on the left and right sides of the push plate 15, hold the handle at the top of the push plate 15 and push it left and right. The push plate 15 passes through the sliding block 14 at the rear end and the sliding rod 13 connected to the sliding block 14 and moves smoothly to the left and right until the cutting is completed.
