[0038] See Figure 1 and Figure 3, the preferred embodiment of the present invention provides a high-precision small roller gap roller device, including a fixed roller 1, a mobile roller 2, a roller shaft driving member 3, a support frame 4, a mobile seat 5, a booster drive assembly 6, a gap adjustment assembly 7, and a displacement sensor 8; the fixed roller 1 is arranged horizontally; the mobile roller 2 is arranged opposite to the fixed roller 1; the roller shaft driving member 3 is used to drive the fixed roller 1 and the mobile roller 2 to rotate; two relatively arranged fixed bearing seats 44 are provided on the support frame 4, and the two ends of the fixed roller 1 are respectively mounted on the two fixed bearing seats 44; two relatively arranged mobile bearing seats 55 are provided on the mobile seat 5, and the two ends of the mobile roller 2 are respectively mounted on the two mobile bearing seats 55, and the mobile seat 5 and the support frame 4 are slidably arranged; the booster drive assembly 6 is installed on the support frame 4, and the booster drive assembly 6 is used to drive the mobile seat 5 applies pressure toward the fixed roller 1; the gap adjustment assembly 7 includes a gap adjustment driver 71 and a gap wedge 72; a first guide member 73 is provided on the side of the movable bearing seat 55 facing the fixed bearing seat 44, and a second guide member 74 is provided on the outer side of the fixed bearing seat 44. The first guide member 73 and the second guide member 74 are arranged opposite to each other, and the gap wedge 72 is slidably connected between the first guide member 73 and the second guide member 74; the gap adjustment driver 71 is located on the outer side of the movable bearing seat 55 and the fixed bearing seat 44, and the surface of the gap wedge 72 facing the first guide member 73 or the second guide member 74 is provided with a first inclined surface 723. The gap adjustment driver 71 is used to drive the gap wedge 72 to move up and down to adjust the distance between the movable seat 5 and the support frame 4; the displacement sensor 8 is used to detect the movement distance of the movable seat 5. When the pair of rollers is started, the boost drive assembly 6 applies pressure to the movable seat 5 toward the fixed roller 1. Since the movable roller 2 is installed on the movable seat 5 and the movable roller 2 is arranged opposite to the fixed roller 1, the movable roller 2 is driven to move forward and roll with the fixed roller 1. The displacement sensor 8 detects the moving distance of the movable seat 5 and outputs a digital signal. At this time, the roller gap is measured manually with a feeler gauge and the difference with the target roller gap size is calculated. The gap adjustment drive 71 works to control the gap wedge 72 to move up and down. During the up and down movement of the gap wedge 72, the movable seat 5 can be pushed close to or away from the support frame 4, driving the movable roller 3 close to or away from the fixed roller 1. At the same time, the displacement sensor 8 detects the moving distance of the movable seat 5 for the second time. When the moving distance detected for the second time is the same as the difference, the gap adjustment drive 71 stops working. At this time, the roller gap size is very small compared with the target size, and the error can be ignored. Finally, the roller shaft drive 3 is started, and the roller shaft drive 3 drives the fixed roller 1 and the movable roller 2 to rotate, completing the whole process of starting the pair of rollers.Since the two ends of the fixed roller 1 are respectively mounted on two fixed bearing seats 44, and the two ends of the movable roller 2 are respectively mounted on two movable bearing seats 55, and a first guide member 73 is provided on the side of the movable bearing seat 55 facing the fixed bearing seat 44, and a second guide member 74 is provided on the outer side of the fixed bearing seat 44, the gap wedge 72 is slidably connected between the first guide member 73 and the second guide member 74, so that the gap wedge 72 is located at the end of the fixed roller 1 and the movable roller 2. Even if the distance between the fixed roller 1 and the movable roller 2 is zero, there is a certain gap between the ends of the two, which can be used to accommodate the gap wedge 72. Therefore, this setting can adjust the roller gap between the fixed roller 1 and the movable roller 2 to a very small size, thereby improving the applicability of the pair of rollers.

[0039] See Figure 3 A fixed block 41 is provided on the outer side of the fixed bearing seat 44. The fixed block 41 is connected to the second guide member 74 toward the side of the movable bearing seat 55. The fixed block 41 facilitates the setting of the second guide member 74, making it convenient to set the first guide member 73 and the second guide member 74 to be relatively set.

[0040] Two first guides 73 are provided on a movable bearing seat 55, and two fixed blocks 41 are provided on a fixed bearing seat 44. Both fixed blocks 41 are connected to second guides 74. The two first guides 73 are located on the upper and lower sides of the movable roller 2, and the two second guides 74 are located on the upper and lower sides of the fixed roller 1. When adjusting the size of the roller gap, the gap wedge 72 can cooperate with the first and second guides 73 and 74 at the upper and lower locations, which helps to make the roller gap size consistent.

[0041] See Figure 1 There are two seam adjustment components 7, which are respectively located at the two ends of the movable roller 2, so that the two ends of the movable roller 2 can move synchronously during the seam adjustment process, which is beneficial to ensure that the size of the roller seam remains consistent after the seam adjustment is completed.

[0042] See Figure 2 The seam adjustment drive 71 includes a seam adjustment explosion-proof motor 711 and a reducer 712. The reducer 712 includes a gear box 713 and a screw rod 714. Figure 2 and Figure 5One end of the screw rod 714 is connected to the gear box 713, and the other end of the screw rod 714 is mounted on the support frame 4 via a bearing 716. The gear box 713 is mounted on the support frame 4. The rotating shaft of the gap adjustment explosion-proof motor 711 is connected to the gear box 713. A screw nut 715 is provided on the screw rod 714, which is rotatably connected to the screw rod 714 and fixedly connected to the gap wedge 72. When the gap adjustment explosion-proof motor 711 is started, its rotating shaft rotates, and the gear box 713 converts the rotation of the rotating shaft into rotation of the screw rod 714. During the rotation of the screw rod 714, the screw nut 715 rises and falls relative to the screw rod 714, thereby driving the gap wedge 72 to rise and fall between the first guide member 73 and the second guide member 74.

[0043] See Figure 6-9 The first guide member 73 includes a first roller slider 51, and the second guide member 74 includes a second roller slider 411. The first roller slider 51 and the second roller slider 411 are arranged opposite each other. Rollers 52 are provided on the opposing sides of the first and second roller sliders 51 and 411, and the gap wedges 72 are slidably connected to the two rollers 52. The rollers 52 can reduce friction during the raising and lowering of the gap wedges 72, making the raising and lowering of the gap wedges 72 smoother.

[0044] See Figure 7-9 The gap wedge 72 includes a sliding portion 721 and a wedge-shaped portion 722. The sliding portion 721 is fixedly connected to the screw nut 715, and the wedge-shaped portion 722 is slidably connected between the two rollers 52. The first inclined surface 723 of the wedge-shaped portion 722 faces the first roller slider 51. The surface of the first roller slider 51 facing the second roller slider 411 is configured as the second inclined surface 511. The first inclined surface 723 and the second inclined surface 511 have the same inclination angle and direction. The first inclined surface 723 of the wedge-shaped portion 722 can cooperate with the second inclined surface 511 of the first roller 52, further facilitating the raising and lowering of the wedge-shaped portion 722.

[0045] In other embodiments, the first inclined surface of the wedge portion may be directed toward the second roller slider, and the surface of the second roller slider directed toward the first roller slider may be set as the second inclined surface, and the lifting and lowering of the wedge portion may be coordinated with the second roller slider.

[0046] See Figure 1 The boost drive assembly 6 includes an oil reservoir 61 and a gas-liquid boost cylinder 62. The oil reservoir 61 is connected to the cylinder body of the gas-liquid boost cylinder 62 via a fluid delivery tube 611. The cylinder body of the gas-liquid boost cylinder 62 is mounted on the support frame 4, and the piston rod of the gas-liquid boost cylinder 62 is used to push the movable base 5. When the gas-liquid boost cylinder 62 is activated, its piston rod extends, pushing the movable base 5 toward the support frame 4, thereby moving the movable roller 2 closer to the fixed roller 1.

[0047] See Figure 4A through hole 42 is provided on the support frame 4, and the piston rod of the gas-liquid booster cylinder 62 is passed through the through hole 42. A ball stud 53 is provided on the side of the movable seat 5 facing the gas-liquid booster cylinder 62. The tail of the ball stud 53 is connected to the movable seat 5 through a pressure sensor 531. The head of the ball stud 53 faces the gas-liquid booster cylinder 62, and the through hole 42 is coaxial with the ball stud 53. When the gas-liquid booster cylinder 62 is started, its piston rod extends and contacts the ball stud 53, and applies pressure to the ball stud 53. The pressure sensor 531 can detect the magnitude of the applied pressure, so the gas-liquid booster cylinder 62 can be controlled to apply a specified amount of pressure. When the roller is opened, the piston rod of the gas-liquid booster cylinder 62 retracts, and a gap is formed between it and the ball stud 53, thereby completing the pressure relief process.

[0048] See Figure 1 The movable seat 5 is provided with a distance measuring strip 54, which is spaced apart from the support frame 4. The distance measuring strip 54 includes a distance measuring portion 541 and a connecting portion 542. The distance measuring portion 541 and the connecting portion 542 are connected in an L-shape, and the connecting portion 542 is fixedly connected to the movable seat 5. A fixing strip 43 is fixedly connected to the support frame 4, and the fixing strip 43 is arranged opposite to the distance measuring portion 541. The displacement sensor 8 is mounted on the fixing strip 43, and the measuring end of the displacement sensor 8 is connected to the distance measuring portion 541. During the movement of the movable seat 5, the distance measuring portion 541 is synchronously driven to move. The distance moved by the distance measuring portion 541 measured by the displacement sensor 8 is the change in the roll gap size.

[0049] See Figure 1 The roller drive 3 includes two roller explosion-proof motors 31. The rotating shafts of the two roller explosion-proof motors 31 are respectively connected to one end of the movable roller 2 and one end of the fixed roller 1. The rotation speeds of the two can be different to achieve differential thinning.

[0050] The end of the fixed roller 1 away from the roller shaft explosion-proof motor 31 and the end of the movable roller 2 away from the roller shaft explosion-proof motor 31 are both connected to an oil guide pipe 11. A heating chamber is provided in the fixed roller 1 and the movable roller 2. The two oil guide pipes 11 are respectively connected to the two heating chambers in the fixed roller 1 and the movable roller 2. Hot oil is introduced into the heating chamber of the fixed roller 1 and the heating chamber of the movable roller 2 through the two oil guide pipes 11, and the circulating hot oil heats the rollers.

[0051] The above is a specific description of the preferred implementation of the present invention, but the invention of the present invention is not limited to the embodiments.

These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
