[0017] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for specific applications.

[0018] Example like Figure 1 、 Figure 2 As shown, in this embodiment, an energy-saving roller hearth heat treatment furnace for wide and thick plates is provided, comprising a furnace body 1, one end of the furnace body 1 being configured as a feed end 2, and the other end being configured as a discharge end 3. Plates to be heated enter the furnace body 1 from the feed end 2, and after being heated, exit from the discharge end 3. The discharge end 3 can be adapted to a conveying mechanism to directly convey the plates to the next process for further processing. In addition, sealing structures are provided in the feed end 2 and the discharge end 3 to achieve heat preservation in the furnace body 1. At the same time, material guide mechanisms can be installed inside the two to enable smooth entry and exit to avoid interference and jamming. These structures are all directly applicable to the existing technology and are therefore not shown in the accompanying drawings. like Figures 1 to 3 As shown, a transmission roller group 4 is installed in the middle of the furnace body 1. The transmission roller group 4 is used to transmit the plate when it moves in the furnace body 1. The transmission roller group 4 consists of a number of single transmission rollers, and the number of single transmission rollers is evenly distributed laterally in the furnace body 1. Both ends of each single transmission roller are rotatably connected to the front and rear side walls of the furnace body 1. At the same time, a sprocket structure is installed at one end of each single transmission roller extending out of the furnace body 1. The multiple sprocket structures can be connected by a chain, so that under the premise of adding an external power source, the entire transmission roller group 4 can be driven to achieve a transmission effect. In the drawings of the present invention, the chain and the external power source are not drawn. They are not improvements and can be adapted using existing technologies. like Figure 3As shown, multiple groups of partitions 5 are arranged in the furnace body 1 at intervals. The partitions 5 divide the cavity of the furnace body 1 into multiple areas, which are the preheating area, heating area, soaking area and cooling area from the feeding end 2 to the discharging end 3. Different areas achieve different heating treatment effects on the plate. A heating assembly 6 using electric heating is provided in the preheating zone, the heating zone, and the soaking zone. The heating assembly 6 is divided into two symmetrical parts, each of which is composed of a resistance belt and a heat-resistant rod. Multiple heat-resistant rods are fixed at the top and bottom of the furnace body 1. Resistance belts are installed at the ends of the opposite heat-resistant rods. The heat generated by the upper and lower resistance belts is radiated to heat the plate. In the present invention, the resistance band is arranged in a wavy shape. The wavy design enables the resistance band to provide a larger heating area within the same volume, thereby improving thermal efficiency. It also promotes natural convection of air, making the heat more evenly distributed in the space, avoiding local overheating, and thus increasing its service life. like Figure 3 、 Figure 4 As shown, the furnace body 1 is further provided with a limiting mechanism 7, which limits the plate on the upper end of the transmission roller group 4 during its transportation to prevent it from running off the track and contacting the inner wall of the furnace body 1, thereby causing jamming and the like. The limiting mechanism 7 in the prior art adopts a design of two rigid side plates. If the plate collides with the side plates due to thermal deformation or deviation, it will cause scratches on the plate surface. If the plate deflects and is not corrected in time, it is easy to cause jamming when the deviation accumulates, affecting the transmission of the plate. Based on this, the limiting mechanism 7 of the present invention adopts an elastic roller group 73 and a correction component to achieve elastic contact with the plate and automatic correction function, thereby protecting the plate and avoiding jamming. In the present invention, Figure 4 As shown, the limiting mechanism 7 includes an adjuster 71, a baffle 72, an elastic roller group 73 and a correction component. The baffle 72 is provided with two symmetrical front and rear parts in each area of the furnace body 1. The baffle 72 is connected to the adjuster 71 extending from the bottom to the furnace body 1. An elastic roller group 73 is provided on the inner side of the baffle 72. A correction component is provided between the elastic roller group 73 and the baffle 72. The adjuster 71 can adjust the distance between the two symmetrical baffles 72, thereby limiting the plate in a large direction to avoid deviation, and the elastic roller group 73 can be used to adjust the distance between the two symmetrical baffles 72. The elastic roller group 73 makes slight contact with the plate when it moves, and relies on its elastic effect to avoid friction and scratches. If the plate tilts or deviates, after it acts on the elastic roller group 73, the elastic roller group 73 will transfer its movement to the correction component for correction. The correction component tilts the entire baffle 72 on the opposite side (for example, if the plate deviates to the left, it acts on the elastic roller group 73 on the left, and the baffle 72 on the right tilts, pushing the plate back to the right). The specific structural design is described as follows: like Figure 4 and Figure 5 As shown, the regulator 71 includes a U-shaped frame 711. The bottom of the U-shaped frame 711 passes through the side wall of the furnace body 1 and is connected to the furnace body 1 through a linear bearing, so that the bottom rod of the U-shaped frame 711 can slide back and forth in the side wall of the furnace body 1. A mounting seat 715 is provided at one end of the bottom of the U-shaped frame 711 located inside the furnace body 1. The mounting seat 715 is L-shaped and has a support plate 716 on its inner side. The support plate 716 is rotatably connected to the baffle 72, so that the baffle 72 can rotate around the center of the support plate 716, thereby having the effect of shifting the plate and returning the plate to the right position. The top of the U-shaped frame 711 is located above the furnace body 1, which is inserted into the shaft seat. The U-shaped frame 711 is slidably connected to the shaft seat, and the shaft seat plays the role of a limit support. The end of the U-shaped frame 711 is connected to the movable plate 712, and the bottom of the movable plate 712 is slidably connected to the upper surface of the furnace body 1. A bidirectional screw rod 713 is installed in the middle of the two front and rear movable plates 712. The bidirectional screw rod 713 can drive the two movable plates 712 to move closer to or away from each other, thereby driving the U-shaped frames 711 on the front and rear sides to move. One end of the bidirectional screw rod 713 is rotatably connected to the fixed plate, and the fixed plate is installed at the upper end of the furnace body 1. An adjusting motor 714 is provided at the other end. The adjusting motor 714 is installed on the motor frame, and the motor frame is fixed on the furnace body 1; When adjusting the distance between the front and rear baffles 72, the adjusting motor 714 is started, which drives the bidirectional screw rod 713 to rotate. After the bidirectional screw rod 713 rotates, it drives the two movable plates 712 to move closer to or away from each other. The movement of the movable plate 712 drives the U-shaped frame 711 to move accordingly. After the movement, the baffle 72 connected to the bottom moves along with it in the furnace body 1, and then the distance between the two symmetrical baffles 72 is automatically adjusted according to the width of the plate, without manual operation, and the operation is simple and convenient. like Figure 6 、 Figure 7 As shown, the baffle 72 is configured as an inverted L-shaped structure, with its outer side rotatably connected to the support plate 716, and an elastic roller group 73 is provided on the inner side. The baffle 72 does not directly contact the plate, and its movement drives the elastic roller group 73 to move, so that the elastic roller group 73 and the plate achieve elastic contact, avoiding scratches on the plate, and can absorb impact and adapt to small deviations. The vertical side wall of the baffle 72 is provided with an inner cavity 721 that passes through it. The inner cavity 721 can realize the circulation of heat when the top and bottom resistance bands are heated. At the same time, a plurality of side grooves 722 are provided on the side of the baffle 72 close to the side of the plate. The side grooves 722 can radiate heat to the side of the plate, heating it and making it heated more evenly, solving the problem that the baffle 72 may block the side of the plate, resulting in uneven heating of the plate. There is also an inclined surface 723 at the top of the side groove 722. The inclined surface 723 is set obliquely upward toward one side of the plate, which can play a reflecting role, concentrating and radiating heat to the side of the plate, achieving faster and more efficient heating. A sliding groove 724 is provided on the lower surface of the horizontal plate of the baffle 72, which has a limiting effect on the roller 733 in the elastic roller group 73. The two are slidingly connected, limiting the roller 733 to move horizontally toward the inner wall of the baffle 72 after being subjected to pressure. like Figure 6 、 Figure 8 and Figure 10 As shown, the elastic roller assembly 73 includes a plurality of connecting plates 731 evenly arranged along the moving direction of the plate and a limiting rod 734 provided corresponding to the connecting plates 731. A slider 732 is provided on the top of the connecting plate 731. The slider 732 is located in the slide groove 724 and can slide in the slide groove 724. A roller 733 is installed at the bottom of the connecting plate 731. The roller 733 can rotate around the axis of the lower part of the connecting plate 731. The rolling form reduces the friction when it contacts the plate, reducing the possibility of scratching. One end of the limiting rod 734 is fixed to the inner wall of the baffle 72, and the other end passes through the connecting plate 731 and is provided with a stopper. The connecting plate 731 can slide horizontally on the limiting rod 734. In addition, a spring 735 is sleeved on the limiting rod 734 between the baffle 72 and the connecting plate 731. The spring 735 is initially in a compressed state, which exerts pressure on the connecting plate 731, causing it to be located at the outermost side of the limiting rod 734. The roller 733 contacts the side of the plate and is a rolling connection method, which reduces friction and avoids scratches. With the above design, when the plate is slightly deflected or deformed or expanded due to heat, the roller 733 is subjected to force. Due to the action of the limiting rod 734, the slider 732, and the slide groove 724, it moves on the limiting rod 734, which slightly compresses the spring 735, thereby increasing the distance between the rollers 733 on both sides. The plate can still be transmitted without jamming. like Figure 7-Figure 9As shown, the correction assembly includes a sleeve plate 8, a correction motor 9, a connecting rod 10, a trigger rod 11, and a trigger 12; one end of the sleeve plate 8 is fixedly connected to the baffle 72, and the other end is sleeved on the support plate 716 and rotatably connected thereto. The correction motor 9 is set on the mounting seat 715, and its motor shaft passes through the support plate 716 and is fixed to the sleeve plate 8. Therefore, after receiving the connection signal between the trigger rod 11 and the trigger 12 on the opposite side, the correction motor 9 can rotate, drive the baffle 72 to deflect, and realize the adjustment of the plate position. There are multiple connecting rods 10, which are fixed between adjacent connecting plates 731, and the connecting plates 731 are fixed in series. A trigger rod 11 is set on the side of the connecting rod 10 close to the baffle 72. There is at least one trigger rod 11, and the number and position of the trigger 12 correspond to the trigger rod 11. The two correspond one to one. In the present invention, Figure 8 As shown, there are two trigger rods 11 and two triggers 12. When multiple trigger rods 11 and triggers 12 are provided, the multiple trigger rods 11 and triggers 12 are all connected in parallel, that is, as long as one of them is effective, the deviation correction action is achieved. One end of the trigger 12 is fixed to the baffle 72, and a gap is left between the end of the trigger 12 that is close to the trigger rod 11 and the trigger rod 11. The gap is adjustable. The trigger rod 11 is a high temperature resistant metal rod with a flat end to prevent sliding dislocation when in contact with the trigger 12. The trigger 12 is composed of multiple structures. The trigger 12 includes an elastic rod 121. One end of the elastic rod 121 is fixed to the side wall of the baffle 72, and the other end is provided with a length-adjustable mounting rod 122. Figure 9 As shown, it consists of two rods of different thicknesses. The thin rod can be adjusted into the thick rod. It is a telescopic rod. There are many specific adjustment methods, such as pins, buckles, etc., which are not limited here. The outer end of the mounting rod 122 is provided with a triggering member 123. After the roller 733 (the front roller 733, i.e. the right side of the plate moving direction) is squeezed, it moves toward the inside of the baffle 72 (moves to the front side). At this time, the connecting rod 10 moves along with it (and moves toward the front side wall of the furnace body 1), which can drive the triggering rod 11 to move together. The movement of the triggering rod 11 will contact the triggering member 123. At this time, the signal is connected. In the process of continuing to move and contact, the elastic rod 121 is compressed. After the signal is connected, the deviation correction motor 9 on the opposite side (the rear side, i.e. the left side of the plate moving direction) receives the signal and starts, which drives the baffle 72 on the opposite side to rotate counterclockwise, and toggles the rear end of the plate moving direction, so that it gradually returns to the center. During the process, the lateral pressure of the plate on the front roller 733 gradually decreases, and the roller 733 gradually returns to its original position under the action of the spring 735. At the same time, it also drives the connecting rod 10 to gradually return to its original position, and the trigger rod 11 also returns to its original position. During the return process, the elastic rod 121 relies on the elastic force to make the trigger member 123 always contact with the trigger rod 11, realizing signal communication, so that the baffle 72 on the opposite side continues to move the plate through the roller 733 until the plate is straightened and its pressure is not enough to squeeze the roller 733 to move a large distance, then the trigger rod 11 is separated from the trigger member 123. At this time, it is determined that the plate is completely returned to the original position, and it will continue to move under the drive roller group 4, while the deviation correction motor 9 on the opposite side stops moving the plate, and it will rotate in the opposite direction to return to its original position; It should be noted here that the trigger member 123 is a device that can realize signal changes after contact. A pressure element can be commonly used. After the trigger rod 11 contacts it, its pressure signal changes, and then the external controller (not drawn in the present invention, the automation control of the equipment adopts the existing technology, and the controller is an automation control component commonly used in current automation equipment, so it is omitted) controls the correction motor 9 to work, drive the baffle 72 to work and reset.

[0019] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
