Embodiment

[0022] Please refer to Figure 1 、 56. The present invention provides a technical solution: a tooling assembly for processing automotive air conditioning filter cotton, wherein two telescopic components are provided on the top of the base 1, the telescopic components include a telescopic rod 10 fixed to the top of the base 1, a connecting plate 14 fixed to the top of the telescopic rod 10, a support column 16 fixed to the top of the connecting plate 14, and a crossbar 17 fixed to the top of the support column 16; a second spring 15 is provided on the outside of the telescopic rod 10; the two ends of the second spring 15 are respectively fixed to the top of the base 1 and the bottom of the connecting plate 14; an L-shaped part 23 is fixed to the outer wall of the connecting plate 14, and an inclined block 24 is fixed to the outer wall of the L-shaped part 23; two fixing components are provided on the crossbar 17, the fixing components include a movable groove 18 opened on the top of the crossbar 17, and a first moving block 19 and a second moving block 20 are movably arranged in the movable groove 18. 19. The top of the second moving block 20 is respectively fixed with a first fixing strip 21 and a second fixing strip 22. The top of the base 1 is provided with a pressing assembly, which includes a first support strip 25 and a second support strip fixed to the top of the base 1. The outer walls of the first support strip 25 and the second support strip are respectively installed with a first bearing 26 and a second bearing. A bidirectional lead screw 27 is installed inside the first bearing 26 and the second bearing. A motor 30 is installed on the outer wall of the first support strip 25. The output end of the motor 30 is connected to the bidirectional lead screw 27 with a coupling. Two lead screw nuts 28 are threaded on the outer wall of the bidirectional lead screw 27. The two lead screw nuts 28 are respectively threaded in two different thread areas of the bidirectional lead screw 27. The outer walls of the two lead screw nuts 28 are each fixed with a pressing block 29 that abuts against the inclined surface of the inclined block 24.

[0023] Specifically, by starting the motor 30, the motor 30 will drive the bidirectional lead screw 27 to work. At this time, the bidirectional lead screw 27 will rotate inside the first bearing 26 and the second bearing. At the same time, the two lead screw nuts 28 will move away from each other between the first support bar 25 and the second support bar. The two lead screw nuts 28 will drive the extrusion block 29 to move accordingly. When the extrusion block 29 abuts against the inclined surface of the inclined block 24, the L-shaped part 23 and the connecting plate 14 will be under pressure, and the telescopic rod 10 and the second spring 15 will retract. At the same time, the support column 16 will drive the crossbar 17 to descend. When the first fixing bar 21 and the second fixing bar 22 abut against the total automotive air conditioning filter cotton, the total automotive air conditioning filter cotton can be fixed, avoiding deviation when cutting the total automotive air conditioning filter cotton, ensuring the cutting effect, and improving the yield of the required automotive air conditioning filter cotton. By starting the motor 30, the motor 30 will drive the bidirectional lead screw 27 to work. At this time, the bidirectional lead screw 27 will rotate inside the first bearing 26 and the second bearing. At the same time, the two lead screw nuts 28 will move closer to each other between the first support bar 25 and the second support bar. The two lead screw nuts 28 will drive the pressing block 29 to move accordingly. When the pressing block 29 does not abut against the inclined surface of the inclined block 24, the L-shaped part 23 and the connecting plate 14 will not be under pressure. Under the action of the second spring 15, the telescopic rod 10 will stretch. At the same time, the support column 16 will drive the horizontal bar 17 to rise. When the first fixed bar 21 and the second fixed bar 22 do not abut against the total automotive air conditioning filter cotton, the cut total automotive air conditioning filter cotton can be cleaned. Since the first moving block 19 and the second moving block 20 are movably set in the movable slot 18, the distance between the first moving block 19 and the second moving block 20 can be adjusted to achieve the purpose of adjusting the distance between the first fixing strip 21 and the second fixing strip 22, so that the first fixing strip 21 and the second fixing strip 22 can meet the cutting needs of different sizes of automotive air conditioning filter cotton, and have a wide range of applications.

[0024] Working principle: First, install the base 1 in the designated area and place the main automotive air conditioning filter cotton on top of the T-shaped placement seat 13. By starting the motor 30, the motor 30 will drive the bidirectional lead screw 27 to work. At this time, the bidirectional lead screw 27 will rotate inside the first bearing 26 and the second bearing. At the same time, the two lead screw nuts 28 will move away from each other between the first support bar 25 and the second support bar. The two lead screw nuts 28 will drive the pressing block 29 to move accordingly. When the pressing block 29 abuts against the inclined surface of the inclined block 24, the L-shaped part 23 and the connecting plate 14 will be under pressure, and the telescopic rod 10 and the second spring 15 will retract. At the same time, the support column 16 will drive the horizontal bar 17 to descend. When the first fixing bar 21 and the second fixing bar 22 abut against the main automotive air conditioning filter cotton, the main automotive air conditioning filter cotton can be fixed. When the electric heating wire is activated again, the temperature of the second cutting frame 7 will rise, activating the hydraulic cylinder 3 at the top of the T-shaped mounting base 2. The hydraulic cylinder 3 uses the connecting rod 4 to drive the first cutting frame 6 and the second cutting frame 7 to descend. The second cutting frame 7 will first contact the main automotive air conditioning filter cotton, completing the initial cutting of the required automotive air conditioning filter cotton. Because the temperature of the second cutting frame 7 is high, the main automotive air conditioning filter cotton will not stick to the required automotive air conditioning filter cotton. After the second cutting frame 7 contacts the main automotive air conditioning filter cotton, the first cutting frame 6 will contact the required automotive air conditioning filter cotton. At this time, the receiving rod 9 will move accordingly in the through hole 8 of the connecting strip 5, and the first spring 12 will also contract. During this process, the first cutting frame 6 will cut off the part of the required automotive air conditioning filter cotton that has been melted by the second cutting frame 7, thus completing the final cutting of the required automotive air conditioning filter cotton. The rotating column 37 drives the threaded rod 36 to move within the threaded hole 35. Driven by the threaded rod 36, the movable block 34 moves accordingly within the movable cavity 33. As the movable block 34 moves, it causes the fixed column 40 to move within the movable hole 38. Once one end of the fixed column 40 disengages from the fixed hole 39, the cutting assembly can be released from its fixation. After the connecting block 32 disengages from the connecting groove 31 at the bottom of the fixed block 41, the cutting assembly can be disassembled, and a new cutting assembly (connecting block 32) can be placed into the connecting groove 31. The rotating column 37 drives the threaded rod 36 to move within the threaded hole 35. Driven by the threaded rod 36, the movable block 34 moves accordingly within the movable cavity 33. When the movable block 34 moves, it drives the fixed column 40 to move within the movable hole 38. When one end of the fixed column 40 is located within the fixed hole 39, the new cutting component can be fixed. Therefore, the cutting component can be replaced. By replacing different cutting components (sizes), different sizes of automotive air conditioning filter cotton can be cut, making it widely applicable. By starting the motor 30, the motor 30 will drive the bidirectional lead screw 27 to work. At this time, the bidirectional lead screw 27 will rotate inside the first bearing 26 and the second bearing. At the same time, the two lead screw nuts 28 will move closer to each other between the first support bar 25 and the second support bar. The two lead screw nuts 28 will drive the pressing block 29 to move accordingly. When the pressing block 29 does not abut against the inclined surface of the inclined block 24, the L-shaped part 23 and the connecting plate 14 will not be under pressure. Under the action of the second spring 15, the telescopic rod 10 will stretch. At the same time, the support column 16 will drive the horizontal bar 17 to rise. When the first fixed bar 21 and the second fixed bar 22 do not abut against the total automotive air conditioning filter cotton, the cut total automotive air conditioning filter cotton can be cleaned. Since the first moving block 19 and the second moving block 20 are movably set in the movable slot 18, the distance between the first moving block 19 and the second moving block 20 can be adjusted to achieve the purpose of adjusting the distance between the first fixing strip 21 and the second fixing strip 22, so that the first fixing strip 21 and the second fixing strip 22 can meet the cutting needs of different sizes of automotive air conditioning filter cotton, and have a wide range of applications.
