[0001] The utility model relates to the technical field of conveying mechanisms, and specifically relates to a conveying mechanism of a tunnel-type high-temperature oven. Background Technique

[0002] A tunnel-type high-temperature oven is a drying equipment that uses a mesh belt to convey products. It can be divided into a single-channel tunnel furnace and a multi-channel tunnel furnace according to the number of channels. It mainly consists of a tunnel furnace chamber, a conveying mechanism, a heating component, and a control system. Among them, the conveying mechanism consists of a driving motor, conveying rollers, a mesh belt, etc. When in use, the driving motor drives the conveying rollers to make the mesh belt run, so that the baked products can be conveyed through the mesh belt and baked, which is relatively convenient to use.

[0003] However, after being used for a period of time, stains will adhere to the surface of the mesh belt of the conveying mechanism. Therefore, it is necessary to clean the mesh belt regularly to ensure the quality of the baked products. At present, most of them mainly clean the mesh belt manually with tools, making the cleaning process more cumbersome and inconvenient. Content of the Utility Model

[0004] Based on this, the purpose of the present utility model is to provide a conveying mechanism of a tunnel-type high-temperature oven to solve the technical problems raised in the above background technique.

The cleaning mechanism includes a water pump, a conduit, and a spray head. A threaded rod is rotatably connected to the bottom end inside the oven main body below the mesh belt. A cleaning brush is threadedly connected to the outside of the threaded rod.

[0006] Preferably, a driving motor is installed at the bottom end inside the oven main body. A pulley set one is sleeved on the outside of the output end of the driving motor and the outside of one of the conveying rollers.

[0007] Preferably, a water pump is installed on the mounting plate inside the water tank. The two ends of the water pump are connected with conduits. The conduits penetrate through one end of the oven main body and are installed with equally spaced spray heads.

[0008] Preferably, a limiting rod is welded and connected to the bottom end inside the oven main body below the mesh belt. Limiting holes are symmetrically opened inside the cleaning brush. The cleaning brush and the oven main body form a sliding structure through the limiting rod and the limiting holes.

[0009] Preferably, a filter screen is provided at the top inside the water tank, and an anti-blocking mechanism is provided between the filter screen and the water tank. The anti-blocking mechanism consists of a support block, a return spring, a cam, a rotating shaft, and a rotating motor.

[0010] Preferably, support blocks are welded and connected to both sides inside the water tank. A return spring is welded and connected between the support block and the filter screen.

[0013] 1. Most of the mesh belts of the conveying mechanism are cleaned manually with tools, making the cleaning process cumbersome and inconvenient. The present utility model is provided with a cleaning mechanism. When the mesh belt needs to be cleaned, the water pump extracts the water in the water tank through the conduit and conveys it towards the nozzle, so that the mesh belt can be flushed through the nozzle. At the same time, since the cleaning brush is threadedly connected to the threaded rod, during the reciprocating forward and reverse rotation of the threaded rod, the cleaning brush makes a reciprocating movement in the horizontal direction, thereby realizing the cleaning of the mesh belt, making the cleaning process relatively simple and fast, and with a high cleanliness;

[0014] 2. The present utility model is provided with a filter screen and an anti-blocking mechanism. During the flushing process, the filter screen is used to filter the stains in the water, so that the water can be recycled, saving water resources. At the same time, the rotating motor is made to work, and the output end of the rotating motor drives the rotating shaft and the cam to rotate. Since the filter screen is elastically connected to the support block through the return spring, during the process of the end of the cam away from the rotating shaft contacting and separating from the filter screen, the filter screen can be impacted and shaken, which is conducive to making the stains move along the water flow to the low-lying areas, facilitating subsequent collection, and at the same time preventing the filter screen from being blocked.

Specific embodiments

[0021] 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. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model, and should not be construed as a limitation of the present utility model.

[0022] Next, according to the overall structure of the present utility model, its embodiments will be described.

[0023] A conveying mechanism of a tunnel-type high-temperature oven, as Figures 1 - 5 shown, includes an oven main body 1 and a conveying mechanism 2. The top end inside the oven main body 1 is provided with a conveying mechanism 2. The conveying mechanism 2 includes a conveying roller 201, a mesh belt 202 and a driving motor 203. The conveying roller 201 is rotatably connected to the top end inside the oven main body 1. The mesh belt 202 is wound around the outside of the conveying roller 201. A driving motor 203 is installed at the bottom end inside the oven main body 1. A pulley set one is sleeved on the outside of the output end of the driving motor 203 and the outside of one of the conveying rollers 201. Place the product on the mesh belt 202, start the driving motor 203, so that the output end of the driving motor 203 drives the conveying roller 201 to rotate under the action of the pulley set one and the mesh belt 202 drives the product into the oven main body 1 for baking treatment.

[0024] Refer to Figures 1 - 5 It can be seen that a filter screen 5 is provided at the top end inside the water tank 4, and an anti-blocking mechanism 6 is provided between the filter screen 5 and the water tank 4. The anti-blocking mechanism 6 consists of a support block 601, a return spring 602, a cam 603, a rotating shaft 604 and a rotating motor 605. Support blocks 601 are welded to both sides inside the water tank 4. A return spring 602 is welded between the support block 601 and the filter screen 5. A rotating shaft 604 penetrating the oven main body 1 is rotatably connected inside the water tank 4. A cam 603 is welded to the outside of the rotating shaft 604. A rotating motor 605 connected to the rotating shaft 604 through a coupling is installed on the mounting plate at one end of the oven main body 1;

[0025] Refer to Figure 1 ,Figure 3 and Figure 4 It can be seen that during the flushing process, the filter screen 5 is used to filter the stains in the water, so that the water can be recycled, saving water resources. At the same time, the rotating motor 605 works, and the output end of the rotating motor 605 drives the rotating shaft 604 and the cam 603 to rotate. Since the filter screen 5 and the support block 601 are elastically connected by the return spring 602, during the process that the end of the cam 603 away from the rotating shaft 604 contacts and separates from the filter screen 5, the filter screen 5 can be impacted and jittered, which is beneficial to make the stains move along the water flow to the low-lying areas, facilitating subsequent collection, and at the same time preventing the filter screen 5 from being blocked.

[0026] Refer to Figures 1 - 5 It can be seen that a water tank 4 is arranged at the bottom end inside the oven main body 1, and a cleaning mechanism 3 extending to the outside is arranged inside the water tank 4. The cleaning mechanism 3 includes a water pump 301, a conduit 302 and a spray head 303. A threaded rod 305 is rotatably connected below the mesh belt 202 inside the oven main body 1. A cleaning brush 304 is threadedly connected to the outside of the threaded rod 305. A pulley group two is sleeved on the outside of the rotating shaft 604 and the threaded rod 305. A water pump 301 is installed on the mounting plate inside the water tank 4. Both ends of the water pump 301 are connected with a conduit 302. The conduit 302 penetrates through one end of the oven main body 1 and spray heads 303 arranged at equal intervals are installed.

[0027] Refer to Figures 1 - 5 It can be seen that when the mesh belt 202 needs to be cleaned, the water pump 301 pumps the water in the water tank 4 through the conduit 302 and conveys it towards the spray head 303, so that the mesh belt 202 can be flushed through the spray head 303. At the same time, since the cleaning brush 304 is threadedly connected to the threaded rod 305, during the process that the threaded rod 305 reciprocates forward and backward, the cleaning brush 304 makes a reciprocating movement in the horizontal direction, so that the mesh belt 202 can be cleaned, making the cleaning process relatively simple and fast, and with a high cleanliness.

[0028] Refer to Figure 1 and Figure 3 It can be seen that a limiting rod is welded and connected below the mesh belt 202 inside the oven main body 1. Limiting holes are symmetrically opened inside the cleaning brush 304. The cleaning brush 304 and the oven main body 1 form a sliding structure through the limiting rod and the limiting holes, which can play a role in supporting and limiting, so that the stability of the cleaning brush 304 during the sliding process can be increased.

[0029] The working principle of the present utility model is as follows: When using the conveying mechanism of the tunnel-type high-temperature oven, the product is placed on the mesh belt 202. At the same time, the driving motor 203 drives the conveying roller 201 to rotate, and the mesh belt 202 drives the product into the oven main body 1 for baking treatment. When it is necessary to clean the mesh belt 202, the water pump 301 extracts the water in the water tank 4 through the conduit 302 and conveys it towards the nozzle 303, so that the mesh belt 202 can be flushed through the nozzle 303. During the reciprocating forward and reverse rotation of the threaded rod 305, the cleaning brush 304 makes a reciprocating motion in the horizontal direction, thereby realizing the rapid cleaning of the mesh belt 202. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
