[0002] A roller hearth furnace is an industrial furnace commonly used in metal heat treatment and ceramic firing, especially suitable for continuous production occasions. It consists of a series of roller barrels that can rotate automatically, allowing workpieces to move smoothly in the furnace. The workpieces move on the roller path, and the rotation of the roller barrels pushes the workpieces through the furnace body. However, when adjusting the position of the saggers through the left - right alignment push plates, when the driving roller path stops rotating, the saggers will still move forward a certain distance in the buffer state. As a result, when adjusting the position of the saggers between the left - right push plates, only the saggers can be kept in the middle position, and multiple saggers are not in a flush state. When the saggers are taken out collectively later, it is necessary to adjust the position of the saggers twice before taking them out simultaneously. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a roller hearth furnace with left - right alignment function to solve the problem that when adjusting the position of the saggers between the left - right push plates, only the saggers can be kept in the middle position, and multiple saggers are not in a flush state as mentioned in the above background art.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] The present utility model provides a roller hearth furnace with left - right alignment function as Figures 1-5 shown, including a roller hearth furnace main body 1 and a plurality of driving rollers 4 installed inside the roller hearth furnace main body 1;

[0026] A plurality of saggar main bodies 7 are arranged between the upper sides of the plurality of driving rollers 4;

[0027] Driving cylinders 10 are fixedly connected to the outer walls at both left and right ends of the roller hearth furnace main body 1;

[0028] Push rods 11 are fixedly connected to the interiors of the two driving cylinders 10. On one side of the opposite surfaces of the two push rods 11, pusher plates 8 are fixedly connected. When the driving rollers 4 in the roller hearth furnace main body 1 transport the saggar main bodies 7, when it moves to the 60 - meter position of the 80 - meter - long roller hearth furnace main body 1, the driving rollers 4 stop driving, so that the saggar main bodies 7 stop. Subsequently, the two driving cylinders 10 simultaneously push out the push rods 11, driving the pusher plates 8 to adjust the positions of the plurality of saggar main bodies 7, and adjusting their positions to the center position of the driving rollers 4. Subsequently, the pusher plates 8 retract, and the driving rollers 4 restart, guiding the plurality of saggar main bodies 7 out of the roller hearth furnace main body 1;

[0029] A baffle 19 is arranged on the lower side of the driving roller 4. Push blocks 20 are respectively arranged on the outer walls of the lower ends of the baffle 19 and close to the left and right sides to push the baffle 19 to move upward under the action of an external force. Driving plates 14 are arranged between the two push blocks 20 and the push plates 8 to drive the push blocks 20 to move. When the two push plates 8 move, they will synchronously drive the driving plates 14 to move, push the push blocks 20 to move the position of the baffle 19 upward. After the baffle 19 moves upward, it is located between the two driving rollers 4, and the distance of the upper end part will limit the moving direction of a plurality of sagger bodies 7, so as to limit the moving position of the sagger bodies 7. If after the baffle 19 is lifted, some of the sagger bodies 7 fail to contact the baffle, the driving roller 4 can be started, so that all the sagger bodies 7 contact the baffle, and then the push plates 8 are retracted, so as to keep the plurality of sagger bodies 7 in a flush state.

[0030] As Figure 3 and Figure 4 shown, connecting rods 13 fixedly connected to the driving plates 14 are fixedly connected to the outer walls of the lower ends of the two push plates 8 to drive the driving plates 14 to move through the push plates 8. A bottom plate 16 is sleeved on the lower side of the baffle 19. A limiting groove 15 is formed in the upper outer wall of the bottom plate 16 to limit the positions of the baffle 19 and the push blocks 20. Limiting blocks 17 are fixedly connected to the inner walls of the lower ends of the limiting groove 15 and close to the left and right sides respectively to limit the positions of the push blocks 20.

[0031] When the push plate 8 moves, it drives the driving plate 14 to move by transmitting kinetic energy through the connecting rod 13. At the same time, when the baffle 19 and the push blocks 20 move, their positions in the up-and-down and left-and-right directions are restricted by the limiting groove 15 of the bottom plate 16.

[0032] As Figure 3 and Figure 4 shown, a plurality of pulleys 18 are equidistantly arranged on the outer walls of the lower ends of the two push blocks 20. The lower ends of the limiting groove 15 and the push blocks 20 are both inclined. A sliding groove is formed in the inner part of the outer wall of the lower end of the baffle 19. Sliding blocks penetrating upward into the sliding groove are arranged on the outer walls of the upper ends of the two push blocks 20 to limit the positions between the push blocks 20 and the baffle 19.

[0033] When the push block 20 moves, the pulley 18 is used to assist in driving the push block 20 to move, reducing the resistance during movement. At the same time, when the inclined limiting groove 15 and the push block 20 move, they can stably drive the baffle 19 to move up and down. When the push block 20 drives the baffle 19 to move up and down, the position of the baffle 19 can be limited through the cooperation of the sliding groove and the sliding block.

[0034] As Figure 1 and Figure 2As shown in the figure, bearing seats 12 are arranged on both the left and right sides of multiple driving rollers 4 to limit the positions of the driving rollers 4 and control the rotation of the driving rollers 4. A stick detection optical fiber bracket 5 is arranged on the left side of each of the multiple driving rollers 4.

[0035] The moving position of the sagger body 7 on the driving roller 4 can be detected through the stick detection optical fiber bracket 5, so as to control the opening and closing of the bearing seat 12, enabling the driving roller 4 to drive the stop and movement of the sagger body 7.

[0036] As Figure 1 and Figure 2 As shown in the figure, cylinder covers 9 are sleeved on the outer sides of two driving cylinders 10 to block dust. A slag discharge pipe 3 is arranged inside the roller hearth furnace body 1. A plurality of supporting feet 2 are fixedly connected to the outer wall of the lower end of the roller hearth furnace body 1 at equal intervals. Ventilation openings 6 are opened on the outer walls of the left and right ends of the roller hearth furnace body 1 near the upper side.

[0037] Covering the driving cylinder 10 with the cylinder cover 9 can prevent dust from entering the gap between the push rod 11 and the driving cylinder 10. At the same time, the residue inside the roller hearth furnace body 1 can be discharged outward through the slag discharge pipe 3 to avoid accumulation. Circulating air through the ventilation openings 6 can maintain the combustion state inside the roller hearth furnace body 1.

[0038] The implementation principle of this embodiment is as follows: When moving to the 60 - meter position of the 80 - meter - long roller hearth furnace body 1, the driving roller 4 stops driving, causing the sagger body 7 to stop. Subsequently, the two driving cylinders 10 simultaneously push out the push rod 11, driving the push plate 8 to adjust the positions of the multiple sagger bodies 7 and adjust their positions to the center position of the driving roller 4. Subsequently, the push plate 8 retracts, and the driving roller 4 restarts, guiding the multiple sagger bodies 7 out of the roller hearth furnace body 1. When the two push plates 8 move, they will synchronously drive the driving plate 14 to move, pushing the pushing block 20 to move the position of the baffle 19 upward. After being lifted, the baffle 19 is located between the two driving rollers 4, and the distance of the upper - end part will limit the moving direction of the multiple sagger bodies 7, thereby restricting the moving position of the sagger body 7. If after the baffle 19 is lifted, some of the sagger bodies 7 fail to abut against the baffle, after starting the driving roller 4 and making all the sagger bodies 7 abut against the baffle, the push plate 8 can be retracted to keep the multiple sagger bodies 7 in a flush state.

[0039] Finally, it should be noted that the above - mentioned are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
