A plurality of groups of heating rollers 16 are arranged between the first fixed plate 10 and the second fixed plate 11. A card slot 17 is provided on both side walls of the plurality of groups of heating rollers 16. A second motor 18 is fixedly connected to one side of the partition 6, and a first rotating shaft 19 is fixedly connected to the output end of the second motor 18. One end of the first rotating shaft 19 passes through the inside of the card slot 17 and is fixedly connected to the card slot 17. A second rotating shaft 20 is arranged at the bottom of the first rotating shaft 19, and a gear 23 is sleeved on the surface of the first rotating shaft 19 and the second rotating shaft 20 on one side of the partition 6.

[0030] Specifically, a limiting groove 7 is provided on the partition plate 6, and one end of each of the two groups of connecting plates 5 passes through the limiting groove 7 and is slidably connected to the inner wall of the limiting groove 7. This structure ensures the stability and accuracy of the connecting plates 5 during operation. The connecting plates 5 are slidably connected to the inner wall of the limiting groove 7, which can effectively limit the position range of the connecting plates 5, avoid unnecessary swinging and deviation, and thus ensure the normal operation of the device.

[0031] Specifically, sliders 8 are fixedly connected to both sides of the connecting plate 5, and slide grooves 9 are opened on both sides of the inner wall of the chassis 1. The sliders 8 are slidably connected to the inside of the slide grooves 9. The sliders 8 fixedly connected to both sides of the structural connecting plate 5 cooperate with the slide grooves 9 opened on the inner wall of the chassis 1 to ensure the stability of the connecting plate 5 during movement. The design of the sliding connection between the slider 8 and the inside of the slide groove 9 provides a controlled sliding path, so that the connecting plate 5 can run smoothly within the specified track.

[0032] Specifically, the side wall of the baffle 13 is slidably connected to the through slot 12, and this structure ensures that the baffle 13 can slide smoothly in the through slot 12. One end of the telescopic spring 14 is fixedly connected to the baffle 13, and the other end of the telescopic spring 14 is fixedly connected to one end of the through slot 12. Through the use of the telescopic spring 14, this structure enables the baffle 13 to achieve an automatic reset function. When the pull rod 15 acts on the baffle 13 to move it, the telescopic spring 14 will be compressed. When the external force disappears, the elastic force of the telescopic spring 14 will push the baffle 13 back to its original position, thereby achieving quick disassembly of the heating roller 16.

[0033] Specifically, one end of the tie rod 15 penetrates the baffle 13 and extends to the inside of the slot 17, and the side wall of the tie rod 15 is fixedly connected to the baffle 13. This structure ensures a close fit between the tie rod 15 and the baffle 13, so that the baffle 13 can be accurately moved and positioned by the force transmitted by the tie rod 15, thereby increasing the stability of the overall structure. One end of the tie rod 15 is plugged into the slot 17, making it easy and quick to install and remove the heating roller 16. The plug-in method is not only easy to operate, but also can be quickly completed when the heating roller 16 needs to be replaced or maintained, thereby improving the work efficiency and maintainability of the device.

[0034] Specifically, pulleys 21 are sleeved on the surfaces of the first rotating shaft 19 and the second rotating shaft 20. The two sets of pulleys 21 are connected by belt drive 22. The belt 22 transmission not only has a higher transmission efficiency, but also has better buffering and shock absorbing capabilities, which can protect the transmission components and improve the stability of the entire device, thereby facilitating the heating and pressurization of the steel belt.

[0035] Specifically, a feed port 25 is provided at one end of the chassis 1, and a discharge port 26 is provided at the other end of the chassis 1, allowing the steel strip to enter from one end and be discharged from the other end, thereby achieving smooth flow and processing of the steel strip. This linear layout helps reduce the risk of material blockage and improve production efficiency. A maintenance door 27 is provided on the front of the chassis 1, and a handle is provided on the surface of the maintenance door 27. The existence of the maintenance door 27 allows the operator to perform necessary internal inspections and repairs without completely disassembling the chassis 1, thereby reducing potential dangers caused by disassembling the chassis 1 and improving the safety of equipment use.

[0036] Working principle: When using the device, when the steel belt pressure inside the chassis 1 is insufficient, first start the first motor 2. When the first motor 2 rotates, it will drive the double-axis screw rod 3 to rotate. When the double-axis screw rod 3 rotates, the threaded connection between the double-axis screw rod 3 and the nut 4 will drive the two connecting plates 5 to approach each other. When the two connecting plates 5 approach each other, they will drive multiple groups of heating rollers 16 to approach each other. At this time, the steel belt inside the chassis 1 is squeezed by the multiple groups of heating rollers 16 approaching each other, which can ensure the extrusion force and heating of the steel belt inside the chassis 1 on the plate. In this way, the normal operation and The work efficiency is improved, and there will be no quality problems with the plate. When the heating roller 16 needs to be replaced, the maintenance door 27 is opened, and then the pull ring 24 is pulled outward. The pull ring 24 drives the pull rod 15 to be pulled outward, so that the pull rod 15 moves out from the inside of the slot 17. When the pull rod 15 is completely moved out of the inside of the slot 17, the telescopic spring 14 is in a compressed state. At this time, the pull rod 15 is moved to the inside of the through slot 12 under the action of the telescopic spring 14, and is separated from the slot 17, thereby realizing the disassembly of the heating roller 16. The operation is simple, the use is extremely convenient, and the efficiency of the steel strip processing process is improved.
