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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0021] Embodiment 1: Please refer to Figure 1-Figure 7The present invention provides a technical solution: a high-speed rail seat cushion cloth cutting device, comprising a cutting table 1, the inner surface of the cutting table 1 is rotatably connected with a first screw rod 2 and a second screw rod 3, the first screw rod 2 is located below the second screw rod 3, and two first motors 4 are fixedly installed on the outer surface of the rear side of the cutting table 1, and the output ends of the two first motors 4 are fixedly connected to the first screw rod 2 and the second screw rod 3 respectively, the outer surface of the first screw rod 2 is threadedly connected with a thread plate 5, the outer surface of the second screw rod 3 is threadedly connected with a thread block 6, the outer surface of the thread plate 5 is fixedly connected with two sliding rods 7, the outer surfaces of the two sliding rods 7 are movably sleeved with a slider 8, the top outer surfaces of the slider 8 and the thread block 6 are fixedly connected with a support rod 9, the top outer surface of the support rod 9 is fixedly connected with a support plate 10, the top outer surface of the support plate 10 is fixedly connected with a portal frame 11, the outer surface of the portal frame 11 is fixedly installed with a first electric push rod 12, and the output end of the first electric push rod 12 is fixedly installed with a pressing plate 13. Specifically, the first electric push rod 12 Working, the first electric push rod 12 near the tail end of the cutting table 1 drives the pressing plate 13 to move downward, so that the pressing plate 13 clamps the end of the pad cloth, and through the operation of another first electric push rod 12, it drives the other pressing plate 13 to clamp the end of the pad cloth near the cutting position. When a piece of pad cloth is cut off, the two first motors 4 work, and the two first motors 4 respectively drive the first screw rod 2 and the second screw rod 3 to rotate. The first screw rod 2 rotates to drive the threaded plate 5 to move, so that the threaded plate 5 drives the portal frame 11 to pull and move one end of the remaining pad cloth, and the second screw rod 3 rotates to drive the threaded block 6 to move to the other side. The two groups of portal frames 11 can be staggered with each other, so that when the threaded plate 5 moves, one group of pressing plates 13 pulls one end of the pad cloth to move, and when the threaded block 6 moves, the other group of pressing plates 13 moves to the next place to be cut to press the pad cloth, and this cycle is repeated. After a piece of pad cloth is cut off, the remaining pad cloth can be transported alternately, thereby improving the cutting efficiency.

[0022] In this embodiment, a gantry 14 is fixedly installed on the top outer surface of the cutting table 1, a second electric push rod 15 is fixedly installed on the top outer surface of the gantry 14, a connecting plate 16 is fixedly installed on the output end of the second electric push rod 15, a vertical plate 19 is fixedly connected to the bottom outer surface of the connecting plate 16, a cutter 20 is installed on the outer surface of the vertical plate 19, a fifth electric push rod is fixedly installed on the top inner surface of the cutting table 1, and a placement plate is connected to the output end of the fifth electric push rod. Specifically, the placement plate is driven upward by the fifth electric push rod so that the pad cloth is placed on top of the placement plate, and then the connecting plate 16 is driven by the second electric push rod 15 so that the cutter 20 contacts the pad cloth to cut the pad cloth.

[0023] In this embodiment, a slide groove 28 is provided on the outer surfaces of the left and right sides of the cutting table 1, and the middle end of the slide groove 28 is concave. The outer surface of the slider 8 is rotatably connected to a rotating shaft 29, and the outer surface of the rotating shaft 29 is fixedly connected to a pulley. The pulley is slidably connected to the inside of the slide groove 28. Specifically, when the slider 8 moves, it drives the rotating shaft 29 to make the pulley slide inside the slide groove 28. When the pulley moves to the concave part of the slide groove 28, the slider 8 slides on the outer surface of the slide rod 7, so that the corresponding portal frame 11 moves downward as a whole.

[0024] In this embodiment, the spacing between the two sliders 8 is smaller than the spacing between the two threaded blocks 6, the width of the gantry 11 located above the sliders 8 is smaller than the width of the gantry 11 above the threaded blocks 6, and four strip grooves are provided on the top outer surface of the cutting table 1. The four support rods 9 are respectively slidably connected to the inside of the four strip grooves. Specifically, the four strip grooves provide channels for the movement of the four support rods 9, and the spacing between the two sliders 8 is smaller than the spacing between the two threaded blocks 6, so that the width of one of the gantry 11 is smaller than the width of the other gantry 11, so that the two gantry 11 can be staggered when moving.

[0025] In this embodiment, a pressure strip is fixedly connected to the bottom outer surface of the pressure plate 13, and a pressure groove is opened on the outer surface of the support plate 10. Specifically, when the first electric push rod 12 drives the pressure plate 13 to move downward, the pressure strip moves downward until the pressure strip is pressed into the inside of the pressure groove, thereby increasing the stability of clamping the pad cloth.

[0026] During the specific implementation process, the pad cloth to be cut is transported to the cutting table 1 and passed under the two pressing plates 13. The first electric push rod 12 works, and the first electric push rod 12 near the tail end of the cutting table 1 drives the pressing plate 13 to move downward, so that the pressing plate 13 clamps the end of the pad cloth, and the other first electric push rod 12 works, which drives the other pressing plate 13 to clamp the end of the pad cloth near the cutting position, and the second electric push rod 15 drives the connecting plate 16 so that the cutter 20 contacts the pad cloth to cut the pad cloth. When a piece of pad cloth is cut off, the two first motors 4 work, and the two first motors 4 respectively drive the first screw rod 2 and the second screw rod 3 to rotate, and the rotation of the first screw rod 2 drives the threaded plate 5 to move When the pulley slides to the concave end of the slide groove 28, the slider 8 slides on the outer surface of the slide rod 7 and moves downward. The second screw rod 3 rotates and drives the threaded block 6 to move to the other side. Because the slider 8 slides and moves downward on the outer surface of the slide rod 7, the two groups of portal frames 11 can be staggered with each other and will not affect the movement of each other. Therefore, when the threaded plate 5 moves, one group of pressing plates 13 pulls one end of the pad cloth to move. When the threaded block 6 moves, the other group of pressing plates 13 moves to the next cutting position to press the pad cloth. This cycle is repeated, so that after a piece of pad cloth is cut, the remaining pad cloth can be transported alternately, thereby improving the cutting efficiency.

[0027] Embodiment 2: Please refer to Figure 1-Figure 7 The present invention provides a technical solution: the front and rear outer surfaces of the connecting plate 16 are rotatably connected to the side plates 17 which are arranged obliquely, and the outer surfaces of the side plates 17 are rotatably connected to the pressure rollers 18. Specifically, the second electric push rod 15 drives the pressure rollers 18 to move downward. When the pressure rollers 18 contact the padding cloth on the placement plate, the pressure rollers 18 pull the padding cloth to both sides, so that the cut parts of the padding cloth are smoothed, thereby improving the flatness of the cutting.

[0028] In this embodiment, the outer surface of the vertical plate 19 is rotatably connected to a plurality of springs 30, and the other ends of the plurality of springs 30 are fixedly connected to the side plates 17. Specifically, when the angle between the two side plates 17 changes, the springs 30 are deformed, and when the springs 30 are reset, they drive the two side plates 17 to reset the two pressure rollers 18.

[0029] In the specific implementation process, when the second electric push rod 15 drives the connecting plate 16 to make the cutter 20 cut downward, the fifth electric push rod works, and the fifth electric push rod drives the placement plate to move upward. The second electric push rod 15 drives the pressure roller 18 to move downward. When the pressure roller 18 contacts the pad cloth on the placement plate, the pressure roller 18 pulls the pad cloth to both sides, so that the cut part of the pad cloth is smoothed, and the flatness of the cutting is improved. When the second electric push rod 15 is retracted, the spring 30 is reset, driving the two side plates 17 to reset the pressure roller 18.

[0030] Embodiment 3: Please refer to Figure 1-Figure 7 The present invention provides a technical solution: a support frame 21 is fixedly connected to the outer surface of the rear side of the cutting table 1, a turntable 23 is rotatably connected to the outer surface of the top of the support frame 21, a side plate 17 is fixedly connected to the outer surface of the turntable 23, a third electric push rod 24 is fixedly installed on the outer surface of the side plate 17, an output end of the third electric push rod 24 is fixedly connected to a C-shaped seat 25, a fourth electric push rod 26 is fixedly installed on the top outer surface of the C-shaped seat 25, and an output end of the fourth electric push rod 26 is fixedly connected to a clamping plate 27. Specifically, when the C-shaped seat 25 is driven by the fourth electric push rod 26 to move, the cutting of the pad cloth is completed, and the fourth electric push rod 26 drives the clamping plate 27 to clamp one end of the pad cloth.

[0031] In this embodiment, a second motor 22 is fixedly installed on the bottom outer surface of the cutting table 1, and the output end of the second motor 22 is fixedly connected to the turntable 23. Specifically, the second motor 22 drives the turntable 23 to rotate, so that the C-shaped seat 25 is located above the conveyor belt 31.

[0032] In this embodiment, a conveyor belt 31 is disposed behind the cutting table 1 , and the conveyor belt 31 is disposed below the support frame 21 . Specifically, the cut pad is placed on the conveyor belt 31 for transportation.

[0033] During the specific implementation process, the fourth electric push rod 26 drives the C-shaped seat 25 to move, and the fourth electric push rod 26 drives the clamping plate 27 to clamp one end of the pad cloth. The second motor 22 drives the turntable 23 to rotate, and the turntable 23 drives the pad cloth to rotate, so that the pad cloth is located above the conveyor belt 31, and the fourth electric push rod 26 is retracted, so that the pad cloth falls onto the conveyor belt 31 for transportation.

[0034] Working principle: When the present invention is in use, the pad cloth to be cut is transported to the cutting table 1 and passed under the two pressing plates 13. The first electric push rod 12 works, and the first electric push rod 12 near the tail end of the cutting table 1 drives the pressing plate 13 to move downward, so that the pressing plate 13 clamps the end of the pad cloth, and another first electric push rod 12 works, which drives the other pressing plate 13 to clamp the end of the pad cloth near the cutting position, and the second electric push rod 15 drives the connecting plate 16 so that the cutter 20 contacts the pad cloth to cut the pad cloth. After a piece of pad cloth is cut off, the two first motors 4 work, and the two first motors 4 respectively drive the first screw rod 2 and the second screw rod 3 to rotate, and the first screw rod 2 rotates to drive the threaded plate 5 moves, so that the threaded plate 5 drives the portal frame 11 to pull and move one end of the remaining pad cloth after cutting. When the pulley slides to the concave end of the slide groove 28, the slider 8 slides on the outer surface of the slide rod 7 and moves downward. The second screw rod 3 rotates and drives the threaded block 6 to move to the other side. Because the slider 8 slides and moves downward on the outer surface of the slide rod 7, the two groups of portal frames 11 can be staggered with each other and will not affect the movement of each other. Therefore, when the threaded plate 5 moves, one group of pressing plates 13 pulls one end of the pad cloth to move, and when the threaded block 6 moves, the other group of pressing plates 13 moves to the next cutting position to press the pad cloth. This cycle is repeated, so that after a piece of pad cloth is cut, the remaining pad cloth can be transported alternately, thereby improving the cutting efficiency.

[0035] When the second electric push rod 15 drives the connecting plate 16 to make the cutter 20 cut downward, the fifth electric push rod works, and the fifth electric push rod drives the placement plate to move upward. The second electric push rod 15 drives the pressure roller 18 to move downward. When the pressure roller 18 contacts the pad cloth on the placement plate, the pressure roller 18 pulls the pad cloth to both sides, so that the cut part of the pad cloth is smoothed and the flatness of the cutting is improved. When the second electric push rod 15 is retracted, the spring 30 is reset, driving the two side plates 17 to reset the pressure roller 18.

[0036] When the C-shaped seat 25 is moved by the fourth electric push rod 26, the cut pad cloth is clamped by the clamping plate 27 driven by the fourth electric push rod 26, and the turntable 23 is driven to rotate by the second motor 22. The turntable 23 drives the pad cloth to rotate, so that the pad cloth is located above the conveyor belt 31, and the fourth electric push rod 26 is retracted, so that the pad cloth falls onto the conveyor belt 31 for transportation.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
