Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent manufacturing of metallurgical machinery, and particularly relates to a double-row roller type guide device for hot steel plate forming. Background Art

[0002] The hot steel plate forming process is a process of directly roll-bending and cutting a high-temperature steel plate. In the roll-bending process, the steel plate needs to be gradually roll-bent into a square tube, a round tube or other roll-bent structures through multiple roll-bending devices. From the previous roll-bending device to the next roll-bending device, it is not a smooth transition. Directly going from the previous roll-bending device to the next roll-bending device will basically cause blockage. To enable the steel plate to normally pass from the previous roll-bending device to the next roll-bending device, a guide device needs to be introduced to achieve this. The guide device smoothly guides the steel plate into the channel of the next roll-bending device, and the channel through which the steel plate passes gradually becomes smaller, so as to ensure that the steel plate can be smoothly roll-bent into the required shape.

[0003] At the present stage, the improvement of the guide device for the hot steel plate forming field adopts a cold-rolled steel guide device. Since the hardness of the cold-rolled steel to be cut is relatively large, the general guide device fixes each guide component after adjusting the guide channel in advance. However, when directly using the cold-rolled steel guide for hot-formed steel plates, because the steel plate has a temperature, its hardness is less than that of the cold-rolled steel, and the forming difficulty is lower than that of the cold-rolled steel. However, due to the problem of being easily blocked and deformed during the guiding process, there needs to be dynamic adjustment during the guiding, especially for the parts that cause obstruction, which can be corrected in real time. Therefore, there is a need for a guide device based on hot processing and forming. When designing, it is necessary to consider which guiding method should be adopted for each surface of the guide device, the position, direction and required state of each component in the guide device, not only to accurately guide the steel plate, but also to adapt to the guiding of various models of products. Therefore, for the hot steel plate forming, it is extremely urgent to design a guide device that can meet the guiding requirements of continuous forming of hot steel plates. Summary of the Invention

[0004] The purpose of the present application is to provide a double-row roller type guide device for hot steel plate forming to solve the problem that hot steel plates are easily blocked in the guide device and cause unnecessary deformation.

[0005] To achieve the above object, the present application provides a hot-rolled steel plate forming double-row roller guiding device, which includes a frame, side roller systems, and an intermediate roller system. The side roller systems are located on both sides of the intermediate roller system. The side roller systems include an upper side roller system and a lower side roller system, and the intermediate roller system includes an upper intermediate roller system and a lower intermediate roller system. The upper side roller system and the lower side roller system are arranged opposite to each other up and down, and gradually converge inward from the feeding end to the discharging end. The upper intermediate roller system and the lower intermediate roller system are arranged opposite to each other up and down. The top of the upper side roller system and the upper intermediate roller system are simultaneously connected with an upper roller system adjusting device for adjusting the height, and the bottom of the lower side roller system and the lower intermediate roller system are simultaneously connected with a lower roller system adjusting device for adjusting the height. The upper roller system adjusting device is symmetrically installed with an upper power source for horizontally adjusting the two sides of the upper side roller system, and the lower roller system adjusting device is symmetrically installed with a lower power source for horizontally adjusting the two sides of the lower side roller system.

[0006] The guiding principle of the present application: During the guiding process, the vertical position relationship between the upper side roller system and the upper intermediate roller system is adjusted through the upper roller system adjusting device, the vertical height of the lower side roller system and the lower intermediate roller system is adjusted through the lower roller system adjusting device, the horizontal distance of the upper side roller system is adjusted through the upper power source, and the horizontal distance of the lower side roller system is adjusted through the lower power source. In this way, the guiding components of the entire guiding device form a forming channel for the steel plate to pass through. Also, because it gradually converges inward from the feeding end to the discharging end, the steel plate to be guided can smoothly move from the previous roll bending mechanism to the next roll bending mechanism.

[0007] Advantages of the present application: 1. The guiding device of the present application separately sets the structures of the side and the middle according to the steel plate to be guided, can achieve perfect fitting of the rolled and bent part, and can ensure the smooth progress of guiding. 2. Each roller system is provided with a separate adjusting mechanism, and even if the rolled and bent steel plate is of a special shape, it can be adapted.

[0008] 3. Also, because the components in the guiding device can be adjusted, the roll bending of the steel plate can be adjusted in real time, solving the problem that the hot-rolled steel plate is easily blocked in the guiding device and generating unnecessary deformation.

[0009] The upper roller system adjusting device includes an upper platform and an upper height lifting device. The upper height lifting device includes an upper height adjustment motor, an upper height adjustment elevator, and an upper height adjustment coupling. There are multiple upper height adjustment elevators. The multiple upper height adjustment elevators are connected to the upper platform through lifting shafts, and the multiple upper height adjustment elevators are rotationally connected to each other in pairs through the upper height adjustment coupling. The upper height adjustment motor drives the upper height adjustment coupling to rotate.

[0010] The upper roller system adjusting device uses the upper platform as a connecting mechanism. As long as the upper platform is moved, the upper side roller system and the upper intermediate roller system can be adjusted, achieving the sharing of the power mechanism during the overall lifting, reducing the use of components, and lowering the cost.

[0011] The lower roll system adjusting device includes a lower platform and a lower height lifting device. The lower height lifting device includes a lower height adjusting motor, a lower height adjusting elevator, and a lower height adjusting coupling. There are multiple lower height adjusting elevators. The multiple lower height adjusting elevators are connected to the lower platform through lifting shafts. The multiple lower height adjusting elevators are rotationally connected to each other in pairs through the lower height adjusting coupling. The lower height adjusting motor drives the lower height adjusting coupling to rotate.

[0012] The design of the lower roll system adjusting device and the design of the upper roll system adjusting device belong to the same concept. The unified adjustment of the lower edge roll system and the lower intermediate roll system is achieved through the adjustment of the lower platform.

[0013] The upper intermediate roll system includes a first upper intermediate roll system and a second upper intermediate roll system. The top surfaces of the first and second upper intermediate roll systems are connected by an upper power mechanism for adjusting the relative distance between them. Both the first and second upper intermediate roll systems are horizontally slidably connected to the upper platform through a slide rail and chute structure. The upper power mechanism includes an upper connecting rod and an upper transverse translation linear motor. The upper transverse translation linear motor is fixedly connected to the upper platform through an upper support. The upper connecting rod includes a left L-shaped connecting rod and a right L-shaped connecting rod. One end of the left L-shaped connecting rod is hinged to the first upper intermediate roll system, and one end of the right L-shaped connecting rod is hinged to the second upper intermediate roll system. The output end of the upper transverse translation linear motor is connected with a telescopic shaft. The left L-shaped connecting rod and the right L-shaped connecting rod are simultaneously hinged on the telescopic shaft.

[0014] Since the hot-rolled steel plate passed through is cut in the middle and the two sides are symmetrically bent steel plates, the upper intermediate roll system needs to guide the two roll bending parts in the middle part. The first and second upper intermediate roll systems designed in this solution are used for guiding at the same time at two places. However, during adjustment, since the two sides of the bent steel plate are symmetric, the first and second upper intermediate roll systems are symmetrically adjusted in two parts through a power mechanism. Here, through the structure of "one end of the left L-shaped connecting rod is hinged to the first upper intermediate roll system, one end of the right L-shaped connecting rod is hinged to the second upper intermediate roll system, the output end of the upper transverse translation linear motor is connected with a telescopic shaft, and the left L-shaped connecting rod and the right L-shaped connecting rod are simultaneously hinged on the telescopic shaft", the telescopic shaft directly drives the L-shaped connecting rods at both ends to rotate around the hinge points. The upper intermediate roll systems on both sides are restricted by the movement directions of the slide rails and chutes, so that the horizontal position adjustment of the first and second upper intermediate roll systems is achieved.

[0015] The lower intermediate roll system includes a first lower intermediate roll system and a second lower intermediate roll system. The top surfaces of the first and second lower intermediate roll systems are connected by a lower power mechanism for adjusting the relative distance therebetween. Both the first and second lower intermediate roll systems are horizontally slidably connected to the lower platform through a slide rail structure. The lower power mechanism includes a lower connecting rod and a lower transverse movement linear motor. The lower transverse movement linear motor is fixed to the lower platform through a lower fixed seat. The lower connecting rod includes a lower left L-shaped connecting rod and a lower right L-shaped connecting rod. One end of the lower left L-shaped connecting rod is hinged to the first lower intermediate roll system, and one end of the lower right L-shaped connecting rod is hinged to the second lower intermediate roll system. The output end of the lower transverse movement linear motor is connected with a telescopic shaft, and the lower left L-shaped connecting rod and the lower right L-shaped connecting rod are simultaneously hinged to the telescopic shaft.

[0016] The movement principle of the lower intermediate roll system is basically the same as that of the upper intermediate roll system. Here, the movement and advantages of the upper intermediate roll system can be referred to.

[0017] The frame includes a parallel front frame and a rear frame. The front frame and the rear frame are fixed to each other. The inner side of the front frame is provided with an upper platform front groove in the upper half and a lower platform front groove in the lower half. The inner side of the rear frame is provided with an upper platform rear groove in the upper half and a lower platform rear groove in the lower half. The upper platform front groove and the upper platform rear groove are at the same position. The two sides of the upper platform are provided with upper platform front sliders and upper platform rear sliders that match the upper platform front groove and the upper platform rear groove. The upper platform front groove has a margin for the upper platform front slider to slide in the vertical direction, and the upper platform rear slider has a margin for the upper platform rear slider to slide in the vertical direction. The two sides of the lower platform are provided with lower platform front sliders and lower platform rear sliders that match the lower platform front groove and the lower platform rear groove. The lower platform front groove has a margin for the lower platform front slider to slide in the vertical direction, and the lower platform rear groove is provided with a margin for the lower platform rear slider to slide in the vertical direction.

[0018] The frame is the basis for installing all roll systems. The limits of the up-and-down movement of the upper platform and the lower platform are restricted by the grooves to avoid excessive adjustment and cause the mechanism to come out.

[0019] A gap is left between the upper platform front groove and the upper platform front slider in the feeding and discharging direction; a gap is left between the lower platform front groove and the lower platform front slider in the feeding and discharging direction.

[0020] After the steel plate enters the guide channel, due to the inherent characteristics of the movement of the steel plate, the positions of the upper platform and the lower platform are slightly higher from the feeding end to the discharging end, so that the upper platform and the lower platform are slightly inclined. A gap is left between the upper platform front groove and the lower platform front groove in the feeding and discharging direction, so that the upper and lower platforms form self-adaptation and prevent the occurrence of jamming.

[0021] The first upper intermediate roll system and the second upper intermediate roll system have the same structure. The two upper intermediate roll systems are on the same horizontal plane and are staggered front and back. The upper intermediate roll system includes an upper support and roll barrel units. A plurality of roll barrel units are arranged in a tapered manner from the feeding end to the discharging end to form a multi-roll path. The tails of the plurality of rolls are connected in series through universal couplings, and the heads are rotatably connected below the upper support; telescopic motors are connected to the tails of the plurality of roll barrel units, and the telescopic motors are fixedly connected to the upper support; the plurality of telescopic motors are connected in series through couplings and are powered by one motor.

[0022] 1. The feature that "a plurality of roll barrel units are arranged in a tapered manner from the feeding end to the discharging end to form a multi-roll path" can gradually guide the steel plate through a plurality of rolls, so as to disperse the force and reduce the pressure on a single roll. 2. The tails of the rolls are connected in series through universal couplings, and telescopic motors are connected to the tails of the plurality of roll barrel units. Since the adjustment ratio of the rolls for guiding is the same, the adjustment of the lengths of a plurality of rolls can be achieved by one motor, reducing the design of power components.

[0023] The upper edge roll system includes a left upper edge roll system and a right upper edge roll system, and the lower edge roll system includes a left lower edge roll system and a right lower edge roll system. The first upper intermediate roll system is axisymmetric with the left upper edge roll system, and the rolls in contact with the steel plate are all inclined, and the inclination direction is the same as the roll bending direction of the steel plate; the second upper intermediate roll system is axisymmetric with the right upper edge roll system, and the rolls in contact with the steel plate are all inclined, and the inclination direction is the same as the roll bending direction of the steel plate with respect to the roll surface.

[0024] The upper edge roll system is divided into two parts, which also meets the requirement of simultaneous guiding in two channels, increasing the versatility of this mechanism.

[0025] The upper power source for horizontally adjusting the two upper edge roll systems and the lower power source for horizontally adjusting the two lower edge roll systems both adopt hydraulic cylinders, screw jacks or linear motors that can perform linear motion.

[0026] Both the left upper edge roll system and the right upper edge roll system are connected with an upper edge adjustment device for horizontal adjustment. The tops of the left upper edge roll system and the right upper edge roll system are slidably connected to the upper platform. Both the left upper edge roll system and the right upper edge roll system are connected with an upper edge adjustment device. The upper edge adjustment device includes a hydraulic cylinder. The telescopic rod of the hydraulic cylinder is hinged to the left upper edge roll system or the right upper edge roll system, and the cylinder body of the hydraulic cylinder is fixedly connected to the upper platform through a connecting accessory.

[0027] The upper edge roll system is horizontally adjusted through the upper edge adjustment device, so that it can quickly reach the position at the initial adjustment, reducing the adjustment time.

[0028] Both the left lower part roller system and the right lower part roller system are connected with a lower part adjusting device for horizontal adjustment. The tops of the left lower part roller system and the right lower part roller system are slidably connected to the lower platform. Both the left lower part roller system and the right lower part roller system are connected with a lower part adjusting device. The lower part adjusting device includes a hydraulic cylinder. The telescopic rod of the hydraulic cylinder is hinged to the left lower part roller system or the right lower part roller system, and the cylinder body of the hydraulic cylinder is fixedly connected to the lower platform through a connecting accessory.

[0029] Similar to the adjustment principle of the upper part roller system, it can make a large-scale horizontal adjustment to the lower part roller system.

[0030] The upper support is divided into an upper support main body installed at the head of the roller monomer and an upper support sub-plate installed at the telescopic rod part of the roller monomer. The upper power mechanism is connected to the top surface of the upper support main body. A slide rail slidably connected to the lower surface of the upper platform is also provided on the top surface of the upper support main body. The upper support sub-plate covers above the telescopic motor, and the telescopic motor is fixedly connected to the upper support sub-plate.

[0031] The upper support sub-plate covers the telescopic rod part and serves as an attachment mechanism for the telescopic motor, which can protect the telescopic rod part to a high degree and also enable the telescopic motor to directly drive the telescopic rod.

[0032] The roller surfaces of the rollers used in the left upper part roller system, the right upper part roller system, the first upper middle roller system, and the second upper middle roller system are all long cylindrical rollers.

[0033] Regarding the roller system in the upper part, it is necessary to apply a roller bending force to the steel plate. By using long cylindrical rollers, the pressure can be evenly applied to the steel plate to achieve the purpose of balanced roller bending force application.

[0034] The left lower part roller system, the right lower part roller system, the first lower middle roller system, and the second lower middle roller system use flat disc-shaped rollers.

[0035] Regarding the roller system in the lower part, the main purpose is to support the upper part roller system and there is no need to apply pressure. Therefore, using flat disc-shaped rollers is sufficient for support, thereby reducing the occupied space and the cost of components.

[0036] Both the front frame and the rear frame are divided into upper and lower U-shaped semi-frames. The upper and lower semi-frames are detachably connected through a flange structure in the middle.

[0037] Both the front frame and the rear frame are divided into upper and lower U-shaped semi-frames. During installation, the roller systems related to the upper platform and the roller systems related to the lower platform can be installed simultaneously respectively. This saves the assembly time, and at the same time, being divided into two parts also reduces the weight of transportation.

[0038] The telescopic motor is a linear motor, specifically a screw jack, and the motor providing power is specifically a gear motor.

[0039] For the convenience of description in this application, in the naming of motors, a lifter, a linear motor or a telescopic motor is used to represent a mechanism capable of linear motion, and a motor or a gear motor is used to represent a power source capable of providing rotational power. In this application, if a structure that can directly achieve the above functions in the prior art is adopted, it is regarded as an equivalent replacement. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] The following is a further detailed description through specific implementation modes:

[0059] Example 1:

[0060] As Figure 1 、 Figure 7 and Figure 10 shown, a hot-rolled steel plate forming double-row roll-type guide device includes a frame 1, an edge roll system and a middle roll system. The edge roll system is located on both sides of the middle roll system. The edge roll system includes an upper edge roll system 2 and a lower edge roll system 5. The middle roll system includes an upper middle roll system 3 and a lower middle roll system 6. The upper edge roll system 2 and the lower edge roll system 5 are arranged opposite to each other up and down and gradually converge inward from the feeding end to the discharging end. The upper middle roll system 3 and the lower middle roll system 6 are arranged opposite to each other up and down. The tops of the upper edge roll system 2 and the upper middle roll system 3 are simultaneously connected with an upper roll system adjusting device 4 for adjusting the height. The bottoms of the lower edge roll system 5 and the lower middle roll system 6 are simultaneously connected with a lower roll system adjusting device 7 for adjusting the height. The upper roll system adjusting device 4 is symmetrically installed with an upper height adjusting gear motor 4-1 for horizontally adjusting the upper edge roll systems on both sides. The lower roll system adjusting device 7 is symmetrically installed with a lower height adjusting gear motor 7-1 for horizontally adjusting the lower edge roll systems on both sides.

[0061] During the guiding process, the vertical position relationship between the upper edge roller system and the upper intermediate roller system is adjusted by the upper roller system adjustment device, the vertical height of the lower edge roller system and the lower intermediate roller system is adjusted by the lower roller system adjustment device, the lateral distance of the upper edge roller system is adjusted by the upper power source, and the lateral distance of the lower edge roller system is adjusted by the lower power source. In this way, the guiding components of the entire guiding device form a forming channel for the steel plate to pass through. Also, since it gradually converges inward from the feeding end to the discharging end, the steel plate being guided can smoothly move from one roll bending mechanism to the next roll bending mechanism.

[0062] As Figure 1 and Figure 7 shown, the upper roller system adjustment device 4 includes an upper platform 4-4 and an upper height lifting device. The upper height lifting device includes an upper height adjustment gear motor 4-1, a height adjustment screw lift 4-3, and an upper height adjustment coupling 4-2. There are multiple height adjustment screw lifts 4-3, and multiple height adjustment screw lifts 4-3 are all connected with lift shafts. The lift shafts drive the upper platform to move up and down. Multiple height adjustment screw lifts 4-3 are rotationally connected in pairs through the upper height adjustment coupling 4-2, and the upper height adjustment gear motor 4-1 drives the upper height adjustment coupling 4-2 to rotate.

[0063] When the upper platform needs to be moved as a whole, only need to start the upper height adjustment gear motor 4-1. The upper height adjustment gear motor 4-1 drives the upper height adjustment coupling 4-2 to rotate. The upper height adjustment coupling 4-2 drives multiple height adjustment screw lifts 4-3 to move synchronously. The outer shell of the height adjustment screw lift is fixed to the frame, and the lift shaft of the height adjustment screw lift can drive the upper platform to move as a whole.

[0064] As Figure 1 and Figure 10 shown, the lower roller system adjustment device includes a lower platform 7-4 and a lower height lifting device. The lower height lifting device includes a lower height adjustment gear motor 7-1, a lower height adjustment screw lift 7-3, and a lower height adjustment coupling 7-2. There are multiple lower height adjustment screw lifts 7-3. Multiple lower height adjustment screw lifts 7-3 are connected to the lower platform 7-4 through lift shafts. Multiple lower height adjustment screw lifts 7-3 are rotationally connected in pairs through the lower height adjustment coupling 7-2, and the lower height adjustment gear motor 7-1 drives the lower height adjustment coupling 7-2 to rotate.

[0065] The way the lower platform moves is similar to that of the upper platform. When the lower platform needs to be moved as a whole, only need to start the lower height adjustment gear motor 7-1. The lower height adjustment gear motor 7-1 drives the lower height adjustment coupling 7-2 to rotate. The lower height adjustment coupling 7-2 drives multiple lower height adjustment screw lifts 7-3 to move synchronously. The outer shell of the lower height adjustment screw lift is fixed to the frame, and the lift shaft of the lower height adjustment screw lift 7-3 can drive the lower platform to move as a whole.

[0066] As Figure 1 and Figure 2 shown, the frame 1 includes parallel front and rear frames. The front and rear frames are fixed to each other, and the upper and lower ends of the front and rear frames are fixedly connected by an upper frame 1-1 and a lower frame 1-2. On the inner side of the front frame, there are an upper platform front groove in the upper half and a lower platform front groove in the lower half. On the inner side of the rear frame, there are an upper platform rear groove in the upper half and a lower platform rear groove in the lower half. The upper platform front groove and the upper platform rear groove are of equal position, and the two grooves form an upper frame groove 1-3. The lower platform front groove and the lower platform rear groove are of equal position, and the two grooves form a lower frame groove 1-4.

[0067] On both sides of the upper platform 4-4, there are an upper platform front slider and an upper platform rear slider that match the upper platform front groove and the upper platform rear groove. The upper platform front groove has a margin for the upper platform front slider to slide in the vertical direction, and the upper platform rear slider has a margin for the upper platform rear slider to slide in the vertical direction; on both sides of the lower platform 7-4, there are a lower platform front slider and a lower platform rear slider that match the lower platform front groove and the lower platform rear groove. The lower platform front groove has a margin for the lower platform front slider to slide in the vertical direction, and the lower platform rear groove has a margin for the lower platform rear slider to slide in the vertical direction.

[0068] The upper platform front slider and the upper platform rear slider on the upper platform form an upper slider 4-5. The lower platform front slider and the lower platform rear slider on the lower platform form a lower slider 7-5;

[0069] There is a gap between the upper platform front groove and the upper platform front slider in the feeding and discharging direction; there is a gap between the lower platform front groove and the lower platform front slider in the feeding and discharging direction.

[0070] After the steel plate enters the guide channel, due to the inherent characteristics of the movement of the steel plate, the positions of the upper platform and the lower platform are slightly higher from the feeding end to the discharging end, so that the upper platform and the lower platform are slightly inclined. There is a gap between the upper platform front groove and the lower platform front groove in the feeding and discharging direction, so that the upper and lower platforms form an adaptation and prevent the occurrence of machine jamming.

[0071] Both the front frame and the rear frame are divided into upper and lower semi-frames with a U-shaped structure, and the upper and lower semi-frames are detachably connected through a flange structure in the middle. By dividing both the front frame and the rear frame into upper and lower semi-frames with a U-shaped structure, when installing, the roller systems related to the upper platform and the roller systems related to the lower platform can be installed simultaneously respectively, which saves assembly time. At the same time, dividing them into two parts also reduces the weight of transportation.

[0072] Embodiment 2:

[0073] As Figure 4 、 Figure 5 and Figure 6As shown in the figure, the upper middle roll system 3 includes a first upper middle roll system and a second upper middle roll system. The top surfaces of the first and second upper middle roll systems are connected by an upper power mechanism for adjusting the relative distance between the two. Both the first and second upper middle roll systems are horizontally slidably connected to the upper platform 4-4 through a slide rail and chute structure. The upper power mechanism includes an upper connecting rod 3-3 and an upper transverse movement gear motor 3-1. The upper transverse movement gear motor 3-1 is fixedly connected to the upper platform 4-4 through an upper support 3-4. The upper connecting rod 3-3 includes a left L-shaped connecting rod 3-3-1 and a right L-shaped connecting rod 3-3-2. One end of the left L-shaped connecting rod is hinged to the first upper middle roll system, and one end of the right L-shaped connecting rod 3-3-2 is hinged to the second upper middle roll system. The output end of the upper transverse movement gear motor 3-1 is connected to an upper transverse movement screw lift 3-2. The upper transverse movement screw lift 3-2 is provided with a telescopic shaft. The left L-shaped connecting rod 3-3-1 and the right L-shaped connecting rod 3-3-2 are simultaneously hinged to the telescopic shaft.

[0074] The first and second upper middle roll systems with simultaneous guard guides at two places are adopted. However, during adjustment, since the two sides of the rolled steel plate are symmetrical, the first and second upper middle roll systems are symmetrically adjusted in two parts through a single power mechanism. Here, through the structure of "one end of the left L-shaped connecting rod is hinged to the first upper middle roll system, one end of the right L-shaped connecting rod is hinged to the second upper middle roll system, the output end of the upper transverse linear motor is connected with a telescopic shaft, and the left L-shaped connecting rod and the right L-shaped connecting rod are simultaneously hinged to the telescopic shaft", the telescopic shaft directly drives the L-shaped connecting rods at both ends to rotate around the hinge points. The upper middle roll systems on both sides are restricted by the movement directions of the slide rails and chutes, thus realizing the adjustment of the horizontal positions of the first and second upper middle roll systems.

[0075] The first upper middle roll system and the second upper middle roll system have the same structure. The two upper middle roll systems 3 are in the same horizontal plane and are staggered front and back. The upper middle roll system 3 includes an upper support 3-4 and roll barrel monomers 3-10.
