[0036] Please see the attached Figure 1-6In one embodiment, the present invention provides a parallel roller system, comprising a balanced pushing assembly 30, a first roller assembly 10 and a second roller assembly 20 spaced apart along the longitudinal direction. First of all, it should be noted that the transverse direction in this application refers to the extension direction of the roller, and the longitudinal direction refers to the rolling direction of the roller (steel coil) perpendicular to the transverse direction; this is different from the prior art in that in some cases the two rollers are flared relative to each other, resulting in them not being parallel to each other. In this way, between the forward and reverse rotations, the originally flat end surface may have quality problems such as sheathing or towering, resulting in the originally intact steel coil 40 being downgraded due to the excessive coil shape, which greatly restricts product quality and increases production costs. The present application solves the above-mentioned defects in the prior art by setting up a parallel roller system, as follows:

[0037] The first roller assembly 10 includes a first support assembly 110, a first roller 120, and two first bearing blocks 130 disposed opposite to each other in the transverse direction. Both ends of the first roller 120 are rotatably connected to the first bearing blocks 130, and the first bearing blocks 130 are fixed to the first support assembly 110.

[0038] The second roller assembly 20 includes a second support assembly 210, a second roller 220, and two second bearing blocks 230 disposed opposite to each other in the transverse direction. Both ends of the second roller 220 are rotatably connected to the second bearing blocks 230, and the second bearing blocks 230 are movably connected to the second support assembly 210 in the longitudinal direction.

[0039] The balanced pushing assembly 30 includes a connecting pipe 310 and two pushing units 320 arranged opposite to each other in the transverse direction. Each pushing unit 320 includes an oil cylinder 321 and a guide rod 322. The first end of the guide rod 322 is connected to the second bearing seat 230, and the second end of the guide rod 322 is connected to the driving end of the oil cylinder 321. The two ends of the connecting pipe 310 are respectively connected to the two oil cylinders 321.

[0040] Specifically, the parallel roller system in the present application includes a balanced pushing assembly 30, a first roller assembly 10 and a second roller assembly 20. The first roller assembly 10 and the second roller assembly 20 are arranged at intervals along the longitudinal direction to facilitate the placement of the steel coil 40. The balanced pushing assembly 30 is used to push and adjust the position of the rollers in the second roller assembly 20, thereby ensuring that the positions of the rollers in the first roller assembly 10 and the rollers in the second roller assembly 20 are parallel.

[0041] Among them, the first roller assembly 10 includes a first support assembly 110, a first roller 120 and two first bearing seats 130 arranged opposite to each other in the transverse direction. It adopts a fixed installation method to ensure that the position of the first bearing seat 130 remains unchanged, thereby maintaining the extension direction of the first roller 120 installed in the first bearing seat 130 unchanged (in the transverse direction); and the second roller assembly 20 includes a second support assembly 210, a second roller 220 and two second bearing seats 230 arranged opposite to each other in the transverse direction. It adopts a movably connected method of the second bearing seat 230 to facilitate the adjustment of the position of the second bearing seat 230, so that when the extension direction of the second roller 220 installed in the second bearing seat 230 is not parallel to the first roller 120, it can be adjusted by the balancing push assembly 30, so that the second bearing seat 230 is movably connected to the second support assembly 210 in the longitudinal direction.

[0042] Among them, the balanced pushing assembly 30 includes a connecting pipe 310 and two pushing units 320 arranged opposite to each other in the transverse direction. The two pushing units 320 are used to push the two second bearing seats 230 respectively to adjust the position of the second bearing seat 230. Each of the pushing units 320 includes a cylinder 321 and a guide rod 322. The pushing effect is achieved by the cylinder 321, and the guide rod 322 is used to connect between the cylinder 321 and the second bearing seat 230. Since the temperature of the steel coil 40 arriving at the roller is usually between 500°C and 800°C, the high temperature generated is easy to affect the cylinder 321. Therefore, the guide rod 322 is added to set the cylinder 321 to a position away from the roller and away from the heat source to extend the service life of the cylinder 321, and then the pushing effect is completed by the guide rod 322; the connecting pipe 310 is used to balance the internal pressure of the two cylinders 321 The force is generated by the communicating vessel, which utilizes the principle of the communicating vessel. The two ends of the communicating pipe 310 are connected to the two oil cylinders 321 respectively. In this way, when one of the second bearing seats 230 is subjected to a large force, the force it receives will react to the oil cylinder 321 connected thereto, causing the driving end (piston rod) of the oil cylinder 321 to retract. At this time, the pressure in the oil cylinder 321 is high, and under the effect of the communicating vessel, the oil flows to the other oil cylinder 321 that is connected to each other, achieving pressure balance between the two oil cylinders 321. In this way, the forces on the two second bearing seats 230 are also the same, so that the positions are kept along the transverse coaxial centerline, and the position of the second roller 220 is also extended transversely, that is, parallel to the first roller 120 whose position remains unchanged; in a preferred embodiment, the communicating pipe 310 can adopt a U-shaped pipe with an opening downward, so that the connection with the two oil cylinders 321 is more convenient.

[0043] As a preferred embodiment of the present invention, the second bearing seat 230 is provided with an oblong hole 231 extending along the longitudinal direction, and the second support assembly 210 is provided with a connecting hole 212 corresponding to the oblong hole 231. The aperture of the connecting hole 212 is smaller than the length of the oblong hole 231. The second bearing seat 230 is connected to the second support assembly 210 by a shoulder screw 232 that penetrates the oblong hole 231 and extends into the connecting hole 212, and there is a longitudinal spacing space 233 between the shoulder screw 232 and the oblong hole 231.

[0044] It should be noted that the arrangement of the oblong hole 231 can facilitate the second bearing seat 230 to have a certain amount of movement space while maintaining the limiting connection after the connecting piece is connected, and the connecting hole 212 is used to install the second bearing seat 230 on the second support assembly 210. The one-to-one correspondence between the connecting hole 212 and the oblong hole 231 means that the two are consistent in number, consistent in transverse width and coaxially arranged. The aperture of the connecting hole 212 is set to be smaller than the aperture of the oblong hole 231, so that the installation and connection can be performed by the shoulder screw 232. The shoulder screw 232 can reduce the number of parts and assembly time, and improve assembly efficiency and quality. After installation, the shoulder screw 232 is located at the shoulder part above the second support assembly 210, and a spacing space 233 is formed between it and the oblong hole 231. When the second bearing seat 230 is pushed, this spacing space 233 is the push adjustment range of the second bearing seat 230.

[0045] As a preferred embodiment of the present invention, the guide rod 322 has a heat dissipation channel 3221 inside, and the guide rod 322 is provided with multiple heat dissipation holes 3222 groups arranged at intervals along the longitudinal direction, and each heat dissipation hole 3222 group includes multiple heat dissipation holes 3222 arranged at intervals along the circumferential direction.

[0046] It should be noted that the heat dissipation channel 3221 is used to further dissipate the high temperature heat of the steel coil 40 to reduce the heat directly transferred to the oil cylinder 321 from the second bearing seat 230. At the same time, the heat dissipation purpose is achieved by opening a group of heat dissipation holes 3222 to enhance the heat dissipation effect.

[0047] As a preferred embodiment of the present invention, the first support assembly 110 includes two first support bases 111 arranged opposite to each other in the transverse direction, and the first bearing seat 130 is fixedly connected to the first support bases 111 by bolts;

[0048] The second support assembly 210 includes two second support bases 211 arranged opposite to each other in the transverse direction. The second support base 211 is provided with the connecting hole 212. The second bearing seat 230 passes through the oblong hole 231 through a shoulder screw 232 and extends into the connecting hole 212 to be connected to the second support base 211.

[0049] It is worth noting that, by setting up two first support bases 111 for installing two first bearing seats 130 respectively, since the first support assembly 110 adopts the form of a fixed roller, the first bearing seat 130 can be fixed by bolt connection, which is convenient for disassembly and assembly; and similarly, by setting up two second support bases 211 for installing two second bearing seats 230 respectively, the connecting hole 212 is opened on the second support base 211 to facilitate the connection through the shoulder screw 232.

[0050] As a preferred embodiment of the present invention, it also includes a horizontal side panel 330 and two longitudinal support blocks 340, the first end of the longitudinal support block 340 is fixedly connected to the second support base 211, the second end of the longitudinal support block 340 is cantilevered outward from the first end of the longitudinal support block 340, and the two ends of the horizontal side panel 330 are connected to the second end of the longitudinal support block 340.

[0051] It is worth noting that the longitudinal support block 340 is used for the installation of the lateral side plate 330, which is connected to the second support base 211 in a cantilevered manner, and the lateral side plate 330 is used for the installation and connection of the oil cylinder 321 and serves as a supporting frame. Therefore, the length of the longitudinal support block 340 needs to be greater than the length of the guide rod 322, so that the lateral side plate 330 can be installed on the second end of the longitudinal support block 340 for the installation of the oil cylinder 321.

[0052] Furthermore, a first countersunk hole 234 is provided on the side wall of the second bearing seat 230, and a second countersunk hole 331 is provided on the horizontal side plate 330. The first end of the guide rod 322 is connected to the second bearing seat 230 by being inserted into the first countersunk hole 234, and the connecting end of the oil cylinder 321 is connected to the horizontal side plate 330 by being inserted into the second countersunk hole 331.

[0053] It should be noted that the first countersunk hole 234 can accommodate and position the first end installation connection of the guide rod 322. Similarly, the second countersunk hole 331 can accommodate and position the connection of the connecting end of the cylinder 321, making the connection more convenient and stable through plug-in.

[0054] Furthermore, each of the pushing units 320 further includes a plurality of guide wheels 323 spaced apart along the longitudinal direction, the guide wheels 323 are connected to the longitudinal support block 340 , and the guide rods 322 are connected to the guide wheels 323 .

[0055] It should be understood that the guide wheel 323 can ensure the coaxiality requirements between the cylinder 321, the guide rod 322 and the countersunk hole, and can further ensure the flexibility of the guide rod 322. In this application as a preferred embodiment, the number of the guide wheels 323 can be set to two, so that the two guide wheels 323 are arranged on the longitudinal support block 340 along the longitudinal interval, and the guide rod 322 can be placed on the guide wheel 323, which is more convenient to push.

[0056] Furthermore, the length of the guide rod 322 is 1.7m to 2m.

[0057] It should be noted that the longer the guide rod 322 is, the farther the oil cylinder 321 is from the high-temperature steel coil 40, so that the oil cylinder 321 is less affected by heat and its service life can be extended. In this application as a preferred embodiment, the length of the guide rod 322 can be set to 1.7m~2m, and those skilled in the art can choose according to actual needs.

[0058] Furthermore, the number of the heat dissipation hole 3222 groups is eight, and the eight heat dissipation hole 3222 groups are arranged at intervals along the longitudinal direction.

[0059] It can be understood that the number of the heat dissipation hole 3222 groups can be determined according to the length of the guide rod 322. The greater the number, the better the heat dissipation performance. Preferably, the number of the heat dissipation hole 3222 groups can be set to eight.

[0060] The above are only preferred embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
