DETAILED DESCRIPTION

[0039] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not simply refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. For example, fixed connection / fixed installation can be selected from screw connection, bolt connection, pin connection, key connection, bonding, mortise and tenon connection, welding, riveting and other methods as needed. For detachable connection, screw connection, bolt connection, threaded connection, snap connection, mortise and tenon connection, Velcro connection and other methods can be selected as needed. The various technical features in the creation of the present invention can be combined interchangeably without conflicting with each other.

[0040] See Figure 1-3 and Figure 8The preferred embodiment of the present invention provides a high-efficiency starting 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 driving component 6, a seam adjustment component 7, a displacement sensor 8, and a pullback component 10; the fixed roller 1 is arranged horizontally, and 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; the fixed roller 1 is installed on the support frame 4; the mobile roller 2 is installed on the mobile seat 5, and the mobile seat 5 is slidingly arranged with the support frame 4; the booster driving component 6 is installed on the support frame 4, and the booster driving component 6 is used to apply pressure to the mobile seat 5 The fixed roller 1 approaches the pressure; the pullback assembly 10 is installed on the support frame 4, and the pullback assembly 10 is used to apply a pulling force to the movable seat 5 away from the fixed roller 1; the gap adjustment assembly 7 includes a gap adjustment driver 71 and a gap wedge 72, the gap wedge 72 is slidably connected between the support frame 4 and the movable seat 5, and the surface of the gap wedge 72 facing the movable seat 5 is set as a first inclined surface 723. The gap adjustment driver 71 is used to drive the gap wedge 72 to move up and down, and adjust the distance between the movable seat 5 and the support frame 4 through the matching relationship between the first inclined surface 723 and the movable seat 5; the displacement sensor 8 is used to detect the movement distance of the movable seat 5. When the pressure required by the pair of rollers is small, the boost drive assembly 6 applies a large pressure to the movable seat 5 that exceeds the pressure required by the movable roller 2, so that the movable seat 5 can move quickly, and then applies a pulling force away from the fixed roller 1 to the movable seat 5 through the pullback assembly 10. The pullback assembly 10 can offset a part of the large pressure applied by the boost drive assembly 6, so that the pressure on the movable roller 2 as a whole is the required small pressure. Since the moving roller 2 is installed on the moving seat 5, and the moving roller 2 is arranged opposite to the fixed roller 1, the moving roller 2 is driven to move forward and roll with the fixed roller 1. The displacement sensor 8 detects the moving distance of the moving 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. Since the gap wedge 72 is slidably connected between the support frame 4 and the moving seat 5, the surface of the gap wedge 72 facing the moving seat 5 is set to the first inclined surface 723. The process of the gap wedge 72 moving up and down It can push the movable seat 5 closer to or away from the supporting frame 4, and drive the movable roller 2 closer 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 to the target size, and the error can be ignored. When the pair of rollers is started, the pressure is adjusted by the dual setting of the boost drive component 6 and the pullback component 10, which can make the pressure on the movable seat 5 reach the required pressure quickly, which is beneficial to improving the starting efficiency of the pair of rollers.

[0041] In other embodiments, the surface of the gap wedge facing the support frame can also be set as a first inclined surface. The distance between the movable seat and the support frame can be adjusted through the cooperation relationship between the first inclined surface and the support frame. During the up and down movement of the gap, the support frame can be pushed closer to or away from the movable seat, driving the fixed roller closer to or away from the movable roller.

[0042] In this embodiment, one end of each of the fixed roller 1 and the movable roller 2 is connected to an oil guide pipe 11, and a heating chamber is provided in each of 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 respectively through the two oil guide pipes 11, and the circulating hot oil heats the rollers.

[0043] See Figure 1 and Figure 4 The pullback assembly 10 includes a pullback cylinder 9 and a floating joint 91. The cylinder body of the pullback cylinder 9 is fixed on the support frame 4, and the piston rod of the pullback cylinder 9 is connected to the movable seat 5 through the floating joint 91. When the device is started, the piston rod of the pullback cylinder 9 extends to apply pressure to the movable seat 5 away from the fixed roller 1, so that the pressure on the movable seat 5 can be reduced to the required small pressure. When it is necessary to increase the roller gap, the boost drive assembly 6 is first depressurized, and the pullback cylinder 9 works at the same time, and its piston rod retracts, and the movable seat 5 is pulled back through the floating joint 91, thereby completing the roll opening action. When closing the rolls, the piston rod of the pullback cylinder 9 extends, and pushes the movable seat 5 toward the support frame through the floating joint 91 to assist in closing the rolls.

[0044] There are two pull-back cylinders 9 and two floating joints 91. The two pull-back cylinders 9 are connected to the two ends of the moving seat 5 near the moving roller 2 through two floating joints 91, which makes it easy for the two ends of the moving roller 2 to move synchronously, and helps to keep the size of the roller gap consistent at all locations during the movement process.

[0045] There are two seam adjustment components 7, which are respectively located near 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 at each location remains consistent after the seam adjustment is completed.

[0046] See Figure 2The seam adjustment drive member 71 includes a seam adjustment explosion-proof motor 711 and a reducer 712. The reducer 712 includes a gear box body 713 and a screw rod 714. One end of the screw rod 714 is connected to the gear box body 713. The other end of the screw rod 714 is mounted on the support frame 4 through a bearing 716. The gear box body 713 is mounted on the support frame 4. The rotating shaft of the seam adjustment explosion-proof motor 711 is connected to the gear box body 713. A screw nut 715 is provided on the screw rod 714. The screw nut 715 is rotatably connected to the screw rod 714. The screw nut 715 is fixedly connected to the gap wedge 72; the seam adjustment assembly 7 also includes a first guide member 73 and a second guide member 74. The first guide member 73 and the second guide member 74 are respectively arranged on the opposite sides of the movable seat 5 and the support frame 4, and the gap wedge 72 is located between the first guide member 73 and the second guide member 74. The gap adjustment explosion-proof motor 711 is started, its shaft rotates, and the gear box 713 converts the rotation of the shaft into the 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 block 72 to rise and fall between the first guide member 73 and the second guide member 74.

[0047] See Figure 2 and Figure 6-9 The first guide member 73 includes a first roller slider 51, and the second guide member 74 includes a fixed block 41 and a second roller slider 411. The second roller slider 411 is connected to the support frame 4 via the fixed block 41. The first roller slider 51 and the second roller slider 411 are arranged opposite each other, and rollers 52 are provided on their opposing sides. The gap wedge 72 is slidably connected to the two rollers 52. The rollers 52 can reduce friction during the raising and lowering of the gap wedge 72, making the raising and lowering of the gap wedge 72 smoother.

[0048] 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.

[0049] 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.

[0050] In this embodiment, two first roller sliders 51 are provided at each end of the movable seat 5, and two second roller sliders 411 are provided at each end of the supporting frame 4, and the first roller sliders 51 and the second roller sliders 411 are arranged opposite to each other; two wedge-shaped portions 722 are provided on the gap wedge block 72, and the two wedge-shaped portions 722 are respectively connected to the two ends of the sliding portion 721 near the vertical direction. The two wedge-shaped portions 722 are both slidably connected between the first roller slider 51 and the second roller slider 411, which is conducive to ensuring the stability of the gap wedge block 72 during the lifting process.

[0051] See Figure 1 、 Figure 3 and Figure 4 The boost drive assembly 6 includes an oil tank 61 and a gas-liquid boost cylinder 62. The oil tank 61 is connected to the cylinder body of the gas-liquid boost cylinder 62 via a liquid infusion tube 611. The cylinder body of the gas-liquid boost cylinder 62 is mounted on the support frame 4. 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.

[0052] The support frame 4 is provided with a through-hole 42, through which the piston rod of the gas-liquid booster cylinder 62 is inserted. A ball stud 53 is provided on the side of the movable base 5 facing the gas-liquid booster cylinder 62. The tail of the ball stud 53 is connected to the movable base 5 via a pressure sensor 531, and the head of the ball stud 53 faces the gas-liquid booster cylinder 62. The through-hole 42 and the ball stud 53 are arranged coaxially. When the gas-liquid booster cylinder 62 is activated, its piston rod extends and contacts the ball stud 53, applying pressure to the ball stud 53. The pressure sensor 531 can detect the amount of pressure applied, thereby controlling the gas-liquid booster cylinder 62 to apply a specified amount of pressure. When the roller is opened, the piston rod of the gas-liquid booster cylinder 62 retracts, forming a gap between it and the ball stud 53, thereby completing the pressure relief process.

[0053] 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.

[0054] See Figure 1The roller drive 3 includes two explosion-proof motors 31, the shafts of which are connected to one end of the movable roller 2 and one end of the fixed roller 1, respectively. Specifically, the shafts of the two explosion-proof motors 31 are connected to the end of the movable roller 2 away from the oil guide tube 11 and the end of the fixed roller 1 away from the oil guide tube 11, respectively. The fixed roller 1 and movable roller 2 are independently controlled, and their rotational speeds can be different to achieve differential thinning.

[0055] See Figure 10 The high-efficiency starting roller device is also equipped with an inspection assembly 12, which includes a bracket 121, a reflector 122, and a lamp (not shown). The bracket 121 is rotatably connected to the movable base 5, the reflector 122 is mounted on the bracket 121, and the lamp is located at the bottom of the support frame 4. The device is placed in a box during actual use. To facilitate the inspection of the real-time film thinning of the material by the device, a lamp is provided to illuminate the roller gap between the movable roller 2 and the fixed roller 1. The bracket 121 is rotated to adjust the angle of the reflector 122, which allows the user to observe the crushing of the material in the roller gap.
