[0017] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0018] Example:

[0019] like Figures 1 to 7 As shown, an automatic band saw cutting device for cold storage panels according to an embodiment of the present invention comprises a base 1, a frame 11 arranged on the base 1, and a band saw blade 12 arranged on the frame 11.

[0020] A ventilation duct 2 is installed on the outer wall of the frame 11, and an exhaust fan is externally connected to the ventilation duct 2. A ventilation plate 21 is installed on the inner wall of the ventilation duct 2. A band saw groove 22 is opened inside the ventilation duct 2. The bottom end of the band saw groove 22 is connected to the ventilation duct 2. A plurality of bristles 23 are connected to the bottom end of the ventilation plate 21. The outer walls of both sides of the band saw blade 12 are jointly attached with a grinding block 3, and two support plates 31 are symmetrically slidably connected inside the grinding block 3. One end of the two support plates 31 away from the grinding block 3 is connected to the inner wall of the ventilation duct 2. A reset mechanism 4 is provided on the ventilation plate 21 for driving the grinding block 3 to reciprocate. The bottom end of the ventilation plate 21 is rotatably connected to a movable plate 5 , and the movable plate 5 is located at the front end of the band saw blade 12 . A driving mechanism 6 is installed inside the ventilation duct 2 to push the movable plate 5 to swing.

[0021] Specifically, when the band saw blade 12 is cutting, the exhaust fan connected to the ventilation duct 2 is started so that the debris generated by the cutting of the band saw blade 12 is attracted by the wind, thereby achieving the effect of dust removal. The grinding block 3 is driven to move laterally on both sides of the band saw blade 12 through the reset mechanism 4, so that the band saw blade 12 can move along the side wall of the grinding block 3 to maintain the stability of the band saw blade 12 during the cutting process. At the same time, the grinding block 3 can push away the debris at the front end of the band saw blade 12 during the forward movement. Under the action of the driving mechanism 6, the movable plate 5 can be driven to swing, and with the help of the exhaust fan and the brush 23, the generated debris can be cleaned and absorbed in time, thereby reducing the splashing of debris, ensuring the surrounding air environment, and further reducing the inhalation of debris by surrounding staff, thereby ensuring the personal health of the staff.

[0022] Please refer to Figure 2 , Figure 5 , the reset mechanism 4 includes a micro motor 41, a first rotating rod 42, a first cam 43, a spring 44 and a sliding member 45; A micro motor 41 is installed on the ventilation plate 21, and the output end of the micro motor 41 is sleeved with a first rotating rod 42. The side wall of the first rotating rod 42 is rotatably connected to the ventilation plate 21, and the bottom end of the first rotating rod 42 is connected to a first cam 43. The side wall of the first cam is attached to the outer wall of the grinding block 3, and two springs 44 are connected to the inner wall of the grinding block 3. The other end of each spring 44 is connected to the end of the support plate 31.

[0023] Specifically, the first rotating rod 42 is driven to rotate by the micro motor 41, so that the first rotating rod 42 drives the first cam 43 to rotate. While the first cam 43 rotates, it will continuously squeeze the grinding block 3, so that the grinding block 3 slides on the support plate 31, so that the spring 44 inside the grinding block 3 is pulled and deformed. Under the action of the first cam 43, in conjunction with the spring 44, the grinding block 3 can move back and forth on the support plate 31, so that the front end of the grinding block can push away the debris generated by the cutting of the band saw blade 12 and the cold storage plate.

[0024] Please refer to Figure 5 , the sliding member 45 includes a T-shaped slot 451 and a T-shaped block 452; Two groups of T-shaped slots 451 facing each other are formed inside the grinding block 3 . A T-shaped block 452 is slidably connected inside each T-shaped slot 451 . Each T-shaped block 452 is connected to the side wall of the support plate 31 .

[0025] Specifically, when the grinding block 3 moves on the support plate 31, the T-shaped block 452 on the support plate 31 will slide in the T-shaped groove 451 inside the grinding block 3, thereby limiting the moving position distance of the grinding block 3 and preventing the grinding block 3 from detaching from the outer wall of the support plate 31.

[0026] Please refer to Figure 3 , Figure 6 , the driving mechanism 6 includes a connecting plate 61, a second rotating rod 62, a second cam 63, a first connecting rod 64 and a second connecting rod 65; Two connecting plates 61 are connected to the inner wall of the ventilation duct 2, and the second rotating rods 62 are rotatably connected inside the two connecting plates 61. The bottom ends of the two second rotating rods 62 are connected to the second cams 63, and the side walls of the two second cams 63 are both attached to the outer wall of the movable plate 5. The top ends of the two second rotating rods 62 are connected to the first connecting rod 64, and the other ends of the two first connecting rods 64 are hinged to the second connecting rod 65, and the other ends of the two second connecting rods 65 are rotatably connected to the top of the grinding block 3.

[0027] Specifically, the grinding block 3 drives the second connecting rod 65 to move while moving back and forth, so that the second connecting rod 65 drives the first connecting rod 64 to rotate on the second rotating rod 62, so that the second cam 63 at the bottom end of the second rotating rod 62 rotates synchronously, and the second cam 63 squeezes the movable plate 5. The two second cams 63 rotate in the same direction, so that the second cam 63 can drive the movable plate 5 to swing, so that the debris stuck to the bristles 23 can be knocked off and can be sucked away by the fan, thereby accelerating the absorption of debris inside the ventilation duct 2 area.

[0028] Please refer to Figure 6 , Figure 7 Two groups of movable components 7 are symmetrically connected to the bottom end of the ventilation plate 21, and two abutment blocks 8 are respectively connected to the two sides of the outer wall of the grinding block 3, and each abutment block 8 is used to drive the movable component 7 to swing.

[0029] Specifically, the grinding block 3 drives the abutment block 8 to move back and forth, thereby driving the movable component 7 to swing, thereby squeezing the bristles 23, so that the debris adhering to the bristles 23 falls off and can be sucked away by the fan, thereby accelerating the absorption of debris inside the ventilation duct 2 area.

[0030] Please refer to Figure 6 , Figure 7 , each movable assembly 7 includes a rotating plate 71 and a third connecting rod 72; The bottom end of the ventilation plate 21 is equidistantly rotatably connected to six rotating plates 71 , the top ends of two adjacent rotating plates 71 are rotatably connected to a third connecting rod 72 , and five third connecting rods 72 are arranged between the six rotating plates 71 .

[0031] Please refer to Figure 6 The outer walls of the two abutment blocks 8 are respectively fitted between two adjacent rotating plates 71 .

[0032] Specifically, the two abutment blocks 8 move back and forth horizontally to squeeze the rotating plate 71 that is in contact with them, so that the rotating plate 71 rotates under the ventilation plate 21. Under the linkage action of multiple third connecting rods 72, multiple rotating plates 71 can be driven to rotate synchronously, thereby accelerating the contact between the rotating plate 71 and the bristles 23, so that the debris stuck on the bristles can fall off quickly, thereby improving the dust removal efficiency of the ventilation duct 2.

[0033] Working principle: When the band saw blade 12 is cutting, the exhaust fan connected to the ventilation duct 2 is started, so that the debris generated by the band saw blade 12 when cutting is attracted by the wind, thereby achieving the effect of dust removal; The first rotating rod 42 is driven to rotate by the micro motor 41, so that the first rotating rod 42 drives the first cam 43 to rotate. While the first cam 43 rotates, it will continuously squeeze the grinding block 3, so that the grinding block 3 slides on the support plate 31, so that the spring 44 inside the grinding block 3 is pulled up and deformed. Under the action of the first cam 43, in conjunction with the spring 44, the grinding block 3 can move back and forth on the support plate 31, so that the front end of the grinding block can push away the debris generated by the cutting of the band saw blade 12 and the cold storage board; The grinding block 3 drives the second connecting rod 65 to move while reciprocating and lateral movement, so that the second connecting rod 65 drives the first connecting rod 64 to rotate on the second rotating rod 62, so that the second cam 63 at the bottom end of the second rotating rod 62 rotates synchronously, so that the second cam 63 squeezes the movable plate 5, and the two second cams 63 rotate in the same direction, so that the second cam 63 can drive the movable plate 5 to swing, so that the debris adhering to the bristles 23 can be knocked off and can be sucked away by the fan, thereby accelerating the absorption of debris inside the ventilation duct 2 area; By reciprocating and moving horizontally through the two abutment blocks 8, the rotating plate 71 that is in contact with it is squeezed, and then the rotating plate 71 is rotated under the ventilation plate 21. Under the linkage action of multiple third connecting rods 72, multiple rotating plates 71 can be driven to rotate synchronously, thereby accelerating the contact between the rotating plate 71 and the bristles 23, so that the debris stuck on the bristles can fall off quickly, thereby improving the dust removal efficiency of the ventilation duct 2.

[0034] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
