Referring to Figures 1-6, the rotary tunnel furnace includes a furnace body 1 and a baking car 12. The furnace body 1 is provided with a circulation mechanism for driving the baking car 12 to move, and the circulation mechanism is provided with a hanger for mounting the baking car 12. , the hanger is provided with a rotating assembly for rotating the baking car 12, and the hanger is also provided with a guide assembly for adjusting the angle of the hanger, and a support mechanism is provided between the circulation mechanism and the furnace body 1.

In a specific embodiment of the present invention, when in use, the food is placed on the food tray, and then the food tray is placed on the baking car 12, and then the baking car 12 is pushed to the inlet end of the furnace body 1, and the circulation mechanism drives the hoist The end where the piece enters the furnace body 1 is the inlet end. The hanging piece will reciprocate and circulate inside and outside the furnace body 1 under the drive of the circulation mechanism. When the hanging piece moves to the position of the baking car 12, the bottom of the chain 4 Due to the height difference, the boom 7 on the hanger enters the inner upper part of the hanger 3 on the baking car 12 from bottom to top, and then the baking car 12 can be lifted and moved, so that the baking car 12 can move in a straight line in the furnace body 1. At the same time, the rotating assembly is used to rotate itself, so that the baking can be made more comprehensive and even. When the baking car 12 moves to the outlet end of the furnace body 1, the height difference at the bottom of the chain 4 is used again to make the boom 7 on the hanger move down. During the moving process, the baking car 12 first touches the ground, and then the boom 7 continues to move down, so that the baking car 12 can be unloaded, realizing the function of automatic lifting and unloading of the baking car 12, and then the hanger continues to move, from the furnace body 1 The top of the oven passes through and then enters again from the inlet end to continuously feed in and out of the baking car 12, thereby achieving a highly efficient and labor-saving baking effect and a high degree of automation. A plurality of baking cars 12 can exist in the furnace body 1 at the same time. The baking equipment and the baking car 12 used for baking in this embodiment are conventional configurations in the prior art.

The circulation mechanism includes a sprocket set, and the sprocket set includes a large sprocket 5, a small sprocket 13 and a chain 4. The front and rear ends of the furnace body 1 are fixedly connected with supports 16, and the two supports 16 are rotatably connected with a The large sprocket 5 and a small sprocket 13 are connected by a chain 4 between the two large sprockets 5, and the large sprocket 5 is driven by a driving device. Corresponding large chain wheels 5 are connected by synchronous shafts.

The driving device is conventionally arranged in the prior art, and can be driven by a motor to drive the speed reducer, and then drive the large sprocket 5 to rotate.

The two small sprockets 13 on the same sprocket set are arranged below the chain 4 and support the lower part of the chain 4, and are close to the two large sprockets 5 respectively. Through this setting, the height difference between the chain section at the middle position of the bottom of the chain 4 and the chain sections at both ends of the bottom of the chain 4 can be generated, so that when the hanging part passes through here, it can move up and down, which is convenient for automatic picking and placing. car12.

The hanger includes a support rod 8, the support rod 8 is fixedly connected between the inner sides of the two chains 4, the middle part of the support rod 8 is rotatably connected with a connecting rod 9, one end of the connecting rod 9 is fixedly connected with the suspension rod 7, and the other end and the rotating assembly Connection, the top surface of the baking car 12 is fixedly connected with a hanger 3, and the hanger 7 matches the hanger 3.

Due to the height difference of the chain 4, when lifting, the state of the boom 7 is from bottom to top, so that the boom 7 supports the hanger 3 from the inner upper part of the hanger 3, and then lifts the baking car 12, similarly , when unloading baking car 12, the state of boom 7 is from top to bottom, and baking car 12 touches the ground at first in the process of moving down, and then boom 7 continues to move down, thereby breaks away from hanger 3, completes unloading.

The rotating assembly includes a gear 11 and a rack 14. The gear 11 is fixedly connected to the outer ring surface of the other end of the connecting rod 9. The rack 14 is fixedly connected to the inner top surface of the furnace body 1. The gear 11 and the rack 14 are engaged.

When in use, after the circulating mechanism drives the baking car 12 into the furnace body 1 through the hanger, under the guidance of the guide assembly, the gear 11 is meshed with the rack 14, and then the connecting rod 9 is rotated, so that the baking car 12 can be rotated. Rotation is carried out in the furnace body 1 to achieve a more uniform baking effect.

The guide assembly includes a guide plate 15 and a guide block 10. The guide block 10 is fixedly connected to the end face of the connecting rod 9 close to the gear 11. The guide plate 15 is fixedly connected to the inner top surface of the furnace body 1. The guide plate 15 is provided with two , respectively arranged at two ends close to the rack 14.

In use, when the guide block 10 passes the guide plate 15, the angle of the direction of the baking car 12 can be adjusted, that is, when the guide block 10 passes the guide plate 15, the guide block 10 will be blocked and then the connecting rod 9 will be forced to rotate, and then Make the side of the guide block 10 coincide with the side near the guide plate 15, so that the axis of the support rod 8 is perpendicular to the side of the furnace body 1, and then when unloading, the suspender 7 can be separated from the hanger 3 smoothly, and the suspender 7 can be separated from the hanger 3 smoothly. 7. The hanger 3 can be hoisted smoothly. The rotary connection of connecting rod 9 and support rod 8 is a rotary connection with damping. This setting can prevent the hanging part from rotating automatically after the hanging part is unloaded from the outlet end of the furnace body 1, so that it is convenient for lifting next time.

The support mechanism includes a guide rail 2 and a pulley 6. The wheel shaft of the pulley 6 is arranged on the outside of the chain 4, and the position of the pulley 6 corresponds to the support rod 8. The wheels of the pulley 6 are arranged in the guide rail 2, and the guide rail 2 is fixedly connected to the furnace body 1. upper part. When the baking car 12 is mounted, the guide rail 2 can be used for support, so as to prevent the chain 4 from bearing too much force.
