A spline groove is provided on the inner wall of the transmission sleeve, and a spline shaft is provided on the outer surface of the transmission shaft 39. Through the meshing of the spline shaft and the spline groove, the transmission shaft 39 can be driven to rotate when the transmission sleeve rotates, and when the transmission shaft 39 moves to one side, it can be disengaged from the spline groove, that is, disengaged from the transmission sleeve. Through the meshing of the active spur gear 24 with the first driven spur gear 22, the idler gear 25, and the second driven spur gear 26, the first transmission sleeve 27 and the second transmission sleeve 28 can be driven to rotate in the opposite direction.

[0039] The right end surface of the driving spur gear 24 is rotatably connected to a first connecting rod 29 , the upper end of which is hinged on the idler gear 25 ; the right end surface of the second driven spur gear 26 is rotatably connected to a second connecting rod 30 , the lower end of which is hinged on the idler gear 25 .

[0041] A transverse plate 51 is fixedly connected to the upper surface of the second installation box 20 , and a second sliding block 52 is rotatably connected to the upper end of the inner box 41 . The second sliding block 52 is slidably connected to the inner wall of the transverse plate 51 .

[0042] like Fig. 9 As shown, the inner box 41 can be slidably connected to the inner wall of the outer box 40 up and down, the cross plate 51 is used to connect the inner box 41, and the second slider 52 can slide left and right on the inner wall of the cross plate 51. The inner box 41 is rotatably connected to the lower end of the second slider 52 through a rotating shaft, that is, the inner box 41 can follow the lower end of the cross plate 51 to move left and right, and when the cross plate 51 moves up and down, it can also drive the second slider 52, the inner box 41, and the pressure roller to move up and down, that is, adjust the position of the upper pressure roller, and the inner box 41 can be rotated at the lower end of the second slider 52 by the rotation connection with the second slider 52.

[0043] The driving seat 32 is slidably connected to the upper end surface of the operating table 1, and the lower end of the driving seat 32 is rotatably connected to the first spur gear 34. The outer box 40 is coaxially fixed to the upper end of the first spur gear 34. A first spur rack 33 slidably connected to the driving seat 32 is meshed on the outer surface of the first spur gear 34. A first sliding pin 35 is fixed to the lower end surface of the first spur rack 33. A track groove matching the first sliding pin 35 is opened on the operating table 1. The track groove includes a transverse groove 36 and an inclined groove 37. When the driving seat 32 moves to the left, the outer box 40 can be limited from rotating by the meshing of the first sliding pin 35 and the transverse groove 36. When the driving seat 32 continues to move to the left, the outer box 40 can be rotated by the meshing of the first sliding pin 35 and the inclined groove 37.

[0044] like Figure 11-Figure 12As shown, the upper surface of the operating table 1 is also fixedly connected to a second telescopic rod 31, which can be an electric rod or an oil rod, and can drive the driving seat 32 to move left and right during operation. The telescopic rod is a prior art and will not be described in detail; the driving seat 32 can be slidably connected to the upper surface of the operating table 1 left and right; the inner wall of the center of the first spur gear 34 is fixedly connected to a rotating shaft, and the outer box 40 is fixedly connected to the upper surface of the rotating shaft, which is equivalent to the first spur gear 34 being coaxially fixed to the outer box 40, that is, when the first spur gear 34 rotates, it can drive the outer box 40 to rotate; the first spur rack 33 can slide back and forth on the lower surface of the driving seat 32, and the installation and shape of the first sliding pin 35, the transverse groove 36, and the inclined groove 37 are as shown in FIG. Fig.12 As shown, when the first sliding pin 35 moves forward and backward, it can drive the first spur rack 33 to move forward and backward, and can also drive the first spur gear 34 to rotate, the outer box 40, and the pressure roller to rotate; when the driving seat 32 moves to the left, it will drive the outer box 40, the first sliding pin 35, the first spur rack 33, the first spur gear 34, the pressure roller, etc. to move to the left synchronously. When the first sliding pin 35 moves to the left, the first sliding pin 35 will not move forward and backward due to the meshing of the first sliding pin 35 and the transverse groove 36, that is, the corresponding first spur gear 34, the outer box 40, etc. will not rotate. When the driving seat 32 moves to the left to make the transmission shaft 39 disengage from the transmission sleeve, that is, the first sliding pin 3 5 enters the inner wall of the inclined groove 37. When the driving seat 32, the first sliding pin 35, etc. continue to move to the left, the first sliding pin 35 will move to the left and move backward under the meshing with the inclined groove 37. When the first sliding pin 35 moves backward, it will drive the first straight rack 33 to move backward. When the first straight rack 33 moves backward, it will drive the first straight gear 34 and the outer box 40 to rotate, so that the outer box 40 and the pressure roller rotate to the front side, which is convenient for users to replace the pressure roller. After replacing the new pressure roller, when the driving seat 32 moves to the right, it will drive the corresponding first sliding pin 35, the outer box 40, etc. to reset, even if the transmission shaft 39 is meshed with the transmission sleeve again, which will not be repeated.

[0045] The inner walls of the right ends of the outer box 40 and the inner box 41 are rotatably connected with connecting screw barrels 43, and the left surface of the pressure roller is provided with connecting screw rods 42 that match the connecting screw barrels 43. The outer box 40 and the inner box 41 are provided with limiting structures that match the connecting screw barrels 43.

[0046] like Fig.10 , Fig.13As shown, the connecting barrel 43 and the connecting screw 42 are threadedly connected, that is, the connecting screw 42 can be detachably installed on the inner wall of the connecting barrel 43, that is, the pressure roller is detachable, and the connecting barrel 43 is rotatably connected to the outer box 40 or the inner box 41. When the pressure roller rotates, its rotation effect is not affected. Through the set limiting structure, the connecting barrel 43 can be limited when necessary, that is, when the pressure roller is disassembled and replaced, the limiting structure can be opened to limit the rotation of the connecting barrel 43. At this time, the connecting screw 42 and the pressure roller can be disassembled. When the limiting structure is closed, the connecting barrel 43 is no longer restricted. At this time, the connecting barrel 43 can rotate with the pressure roller, that is, the pressure roller can work normally.

[0047] The limiting structure includes an outer shaft 45 rotatably connected to the outer box 40, a first slider 44 slidably connected to the operating table 1 is fixedly connected to the lower end surface of the outer shaft 45, an inner shaft 46 rotatably connected to the inner box 41 is slidably connected to the inner wall of the upper end of the outer shaft 45, small spur gears 47 are respectively fixedly connected to the outer surfaces of the outer shaft 45 and the inner shaft 46, small spur racks 48 are respectively meshed on the outer surfaces of the small spur gears 47, toothed discs 50 are respectively fixedly connected to the left end surfaces of the connecting screw barrel 43, and limiting teeth 49 matching with the toothed discs 50 are respectively fixedly connected to the rear ends of the small spur racks 48.

[0048] like Fig.13 or Fig.14 As shown, the first slider 44 can slide left and right on the upper surface of the operating table 1; the outer shaft 45 is connected to the outer box 40 by rotation, and when the outer box 40 moves left and right, it can drive the outer shaft 45 to move left and right. When the outer box 40 rotates, the corresponding outer shaft 45 cannot rotate under the limit of the first slider 44. The outer shaft 45 and the inner shaft 46 are splined, that is, the outer shaft 45 and the inner shaft 46 cannot rotate, and the inner shaft 46 can move up and down on the inner wall of the outer shaft 45; the small spur rack 48 can be slidably connected to the corresponding inner box 41 and the inner wall of the outer box 40 back and forth; the small spur rack 48, the small spur gear 47 limiting teeth 49, and the toothed disc 50 are installed and shaped as shown in the figure Fig.14As shown, an L-shaped rod is fixedly connected to the rear end surface of the small spur rack 48, and the limit tooth 49 is fixedly connected to the L-shaped rod, which is equivalent to the limit tooth 49 being fixedly connected to the small spur rack 48; the small spur gear 47 cannot rotate under the limit of the outer shaft 45 and the inner shaft 46. When the drive seat 32 moves to the left to rotate the outer box 40 and the inner box 41, it can drive the corresponding small spur rack 48, the toothed disc 50, the limit tooth 49, the connecting screw barrel 43, the pressure roller, etc. to move synchronously in a circular motion. When the small spur rack 48 moves in a circular motion, it will be meshed with the small spur gear 47, and the edge will be round. As the small spur rack 48 moves while rotating, it will drive the limit tooth 49 to move. When the limit tooth 49 moves to engage with the toothed disc 50, the limit tooth 49 will limit the rotation of the toothed disc 50 and the connecting screw barrel 43. That is, the limit structure is open at this time, and the pressure roller can be disassembled. When the drive seat 32 moves to the right and resets, the corresponding limit tooth 49 will move to disengage from the toothed disc 50. At this time, the limit structure is closed and no longer limits the rotation of the connecting screw barrel 43, that is, the connecting screw barrel 43 can rotate with the pressure roller, so that the pressure roller can work normally.

[0049] Both sides of the upper end of the operating table 1 are respectively provided with movable sleeves 5, and the inner walls of the sleeves 5 are rotatably connected with guide wheels 6.

[0050] like Figure 3 As shown, the left and right sides of the upper end surface of the operating table 1 are respectively fixed with a first support seat 3, and the inner end surfaces of the two first support seats 3 are respectively fixed with a first telescopic rod 4, and the sleeve seat 5 is respectively sleeved on the corresponding first telescopic rod 4. The first telescopic rod 4 is an electric rod or a pneumatic rod, which can drive the sleeve seat 5 to move inward or outward. The first telescopic rod 4 is a prior art and is not described in detail. Through the set guide wheel 6, the center of the steel belt to be flattened can be calibrated to prevent the steel belt from running off the track. By driving the two sleeve seats 5 to move outward to the specified position according to the width of the steel belt, the steel belt is placed between the two corresponding guide wheels 6, that is, the limited steel belt can only move between the two guide wheels 6, and the sleeve seat 5 can move inward or outward, and can be adaptively adjusted according to the width of the steel belt.

[0051] The left and right sides of the upper end surface of the operating table 1 are respectively fixed with water supply barrels 10, the inner sides of the water supply barrels 10 are respectively connected with nozzles 9, and sealing plates 8 are respectively slidably connected on both sides of the nozzles 9. The upper and lower end surfaces of the sleeve 5 are respectively fixed with connecting rods 7, and the connecting rods 7 are respectively fixed to the corresponding sealing plates 8.

[0052] like Figure 2-Figure 4As shown, the water supply barrel 10 is used to load water, and a water pump is also provided inside the water supply barrel 10. The water pump can pump water to the nozzle 9, so that the water is sprayed out from the nozzle 9. The two nozzles 9 are staggered up and down. When the nozzles 9 are opened, water can be sprayed to the upper and lower ends of the steel belt to wash away the debris on the outer surface of the steel belt, thereby improving the flattening effect, and cooling the steel belt to improve the flattening effect and physical properties of the steel belt; a groove is provided on the operating table 1, and a collecting groove 11 is placed on the inner wall of the groove. A filter screen 12 is placed on the inner wall of the collecting groove 11. The collecting groove 11 and the filter screen 12 can filter the waste liquid after washing, thereby recycling the waste liquid; the sealing plate 8, the nozzle 9, and the connecting rod 7 are installed and shaped as shown in the figure. Figure 4 As shown, the sealing plate 8 can slide left and right on the lower end surface of the nozzle 9. When the two sealing plates 8 move outward, the nozzle 9 can be opened, and when the two sealing plates 8 move inward, the nozzle 9 can be closed. The connecting rod 7 is linked with the sleeve 5. When the sleeve 5 moves outward, the connecting rod 7 and the sealing plate 8 can be driven to move outward. At this time, the nozzle 9 is opened, and the opening size of the nozzle 9 corresponds to the width of the steel belt, so that the water flow is concentrated on the steel belt to reduce waste.

[0053] When the present invention is in use, by starting the first motor 23, with the cooperation of the transmission shaft 39 and the transmission sleeve, when the transmission sleeve rotates, the transmission shaft 39 and the pressure roller can be driven to rotate, that is, the steel strip is flattened. When the handle 15 is rotated, the second installation box 20 can be driven to move up and down, and the corresponding pressure roller, inner box 41, etc. can be driven to move up and down. The spacing between the two pressure rollers can be adjusted and adaptively adjusted according to the thickness of the steel strip; the pressure roller is detachably installed on the outer box 40 and the inner box 41. When the driving seat 32 moves to the left, the outer box 40, the inner box 41, the pressure roller, the transmission shaft 39, etc. can be driven to move synchronously to the left. When the transmission shaft 39 moves to the left, it can be separated from the transmission sleeve. When the driving seat 32 and the pressure roller move to the left to the specified position, they will flip to one side, and it is convenient to disassemble and replace the pressure roller.

[0054] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art to which the present invention belongs may make various modifications or additions to the described specific embodiments or replace them with similar methods.
