Description

Technical Field

[0001] This utility model relates to the field of dryer technology, and in particular to a mesh belt dryer with a tumbling mechanism. Background Technology

[0002] A mesh belt dryer is a drying equipment that uses a steel mesh as a conveyor belt to continuously dry materials. The main principle of a mesh belt dryer is to place the material on the mesh belt, which is made of steel wire mesh with a specific mesh size. The mesh belt is driven by a transmission device to move back and forth or continuously inside the dryer. Hot air flows through the material, either from top to bottom or from bottom to top, so that the material can be dried evenly.

[0003] The current drying methods described above can only ensure that some shaped objects remain in a horizontal position, but the lower surface of the object cannot make good contact with the heat source, resulting in poor drying effect at the bottom. Workers need to turn the object over before putting it into the mesh belt dryer for drying. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mesh belt dryer with a turning mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mesh belt dryer with a turning mechanism includes a housing, an opening at the front end of the housing, and a door rotatably connected to the top of the opening. A drying device is installed inside the housing. Two symmetrical mounting plates are fixed on both sides of the outer wall of the housing. The same mesh belt conveyor mechanism is provided inside the housing and the mounting plates. A turning mechanism is installed inside the housing.

[0007] The flipping mechanism includes a bidirectional motor fixed to the outer wall of the equipment housing. The output shaft of the bidirectional motor is fixed with a mounting rod. The mounting rod has two holes, and the same square ring is inserted into the two holes. An electric push rod is fixed to the top of the mounting rod. The output shaft of the electric push rod is fixed to the square ring. By operating the electric push rod, the height of the square ring can be adjusted, thereby adjusting the height of the flipped object.

[0008] Preferably, baffles are fixed at both ends of the left side of the inner wall of the equipment housing, and the baffles are inclined. By using the baffles, the items can be pushed to the middle of the belt conveyor to make contact with the square ring and achieve smooth subsequent flipping.

[0009] Preferably, a photoelectric sensor is fixed on the inner wall of the device housing near the baffle. The photoelectric sensor is electrically connected to a bidirectional motor and a PLC. When the photoelectric sensor detects an object, it transmits a signal to the PLC, which then controls the bidirectional motor to rotate, thereby rotating the mounting rod and flipping the square ring to relatively overturn the moving object.

[0010] Preferably, the drying device includes an air heat pump fixed to the top of the equipment shell, the air outlet of the air heat pump is fixedly connected to an air supply pipe located inside the equipment shell, and the air supply pipe is fixed to the inner wall of the equipment shell, and several air outlets are evenly installed at both ends of the bottom of the air supply pipe.

[0011] Preferably, the mesh belt conveyor mechanism includes a first drive roller and a second drive roller rotatably disposed between two mounting plates. Two first sprockets are fixedly sleeved on the outer wall of the first drive roller, and two second sprockets are fixedly sleeved on the outer wall of the second drive roller. Both the first and second sprockets are connected by chains. A mesh belt is fixed between the two chains. A drive motor is fixed to the outer wall of the mounting plate and is coaxially fixed to the first drive roller. A first cleaning roller and a second cleaning roller are rotatably disposed on the inner wall of the mounting plate. The first cleaning roller is located inside the conveyor belt and is in close contact with the upper surface of the inner wall. The second cleaning roller is in close contact with the bottom of the conveyor belt. The second drive roller is coaxially fixed with a first gear, which meshes with a second gear. The second gear is coaxially fixed with the first cleaning roller, and the second gear is coaxially fixed with a first synchronous pulley. The first synchronous pulley is connected to a second synchronous pulley via a synchronous belt, and the second synchronous pulley is coaxially fixed with the second cleaning roller. Through the operation of the mesh belt conveyor mechanism, the first gear, which is coaxially fixed with the second drive roller, can rotate, thereby causing the second gear to rotate, which in turn causes the first cleaning roller to rotate. The second gear, connected to the second drive roller, is connected to the second synchronous pulley via a synchronous belt, thus causing the second cleaning roller to rotate. In this way, the first and second cleaning rollers rotate simultaneously, cleaning in a rolling manner and improving the cleaning effect.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The device is equipped with a housing, mounting plate, mesh belt conveyor, drying device, and flipping mechanism. When a photoelectric sensor detects an object, it transmits a signal to the PLC. The PLC controls a bidirectional motor to work, which drives the mounting rod to rotate, thus flipping the square ring and turning the moving object. As the object moves, it flips over. The continuously operating drying device dries the surface of the object. Through the above design, the object can automatically flip over and be dried while moving.

[0014] 2. Through the operation of the mesh belt conveyor mechanism, the first gear, which is fixed coaxially with the second drive roller, can rotate, thereby rotating the second gear, which in turn rotates the first cleaning roller. The second gear, which is connected to the second gear, is connected to the second synchronous pulley via a synchronous belt, thereby rotating the second cleaning roller. In this way, the first and second cleaning rollers can rotate simultaneously and clean in a rolling manner, improving the cleaning effect. Attached Figure Description

[0023] The flipping mechanism 9 includes a bidirectional motor 10 fixed to the outer wall of the equipment housing 1. The output shaft of the bidirectional motor 10 is fixed with a mounting rod 11. Two holes are opened on the mounting rod 11, and the same square ring 12 is inserted into the two holes. An electric push rod 13 is fixed to the top of the mounting rod 11. The output shaft of the electric push rod 13 is fixed to the square ring 12. By operating the electric push rod 13, the height of the square ring 12 can be adjusted, thereby adjusting the height of the flipped contact object.

[0024] In this utility model, baffles 8 are fixed at both ends of the left side of the inner wall of the equipment housing 1, and the baffles 8 are inclined. By using the baffles 8, the items can be pushed to the middle of the belt conveyor 3 to make contact with the square ring 12 and achieve subsequent smooth flipping.

[0025] In this utility model, a photoelectric sensor is fixed on the inner wall of the equipment housing 1 near the baffle 8. The photoelectric sensor is electrically connected to the bidirectional motor 10 and the PLC. When the photoelectric sensor detects an object, it transmits a signal to the PLC, which controls the bidirectional motor 10 to work. The bidirectional motor 10 drives the mounting rod 11 to rotate, thereby flipping the square ring 12 and relative flipping the moving object.

[0026] In this utility model, the drying device includes an air heat pump 5 fixed on the top of the equipment shell 1. The air outlet of the air heat pump 5 is fixedly connected to an air supply pipe 6 located inside the equipment shell 1. The air supply pipe 6 is fixed to the inner wall of the equipment shell 1.

[0027] In this invention, the mesh belt conveyor mechanism includes a first drive roller 15 and a second drive roller 16 rotatably disposed between two mounting plates 2.

A first cleaning roller 17 and a second cleaning roller 18 are rotatably disposed on the inner wall of the mounting plate 2. The first cleaning roller 17 is located inside the belt conveyor 3 and is in close contact with the upper surface of the inner wall. The second cleaning roller 18 is in close contact with the bottom of the belt conveyor 3. The second drive roller 16 is coaxially fixed to the first drive roller 15. Gear 19 meshes with a second gear 20, which is coaxially fixed to the first cleaning roller 17. A first synchronous pulley 21 is coaxially fixed to the second gear 20. The first synchronous pulley 21 is connected to a second synchronous pulley 23 via a synchronous belt 22. The second synchronous pulley 23 is coaxially fixed to the second cleaning roller 18. Through the operation of the mesh belt conveyor mechanism, the first gear 19, which is coaxially fixed to the second transmission roller 16, can rotate, thereby rotating the second gear 20, which in turn rotates the first cleaning roller 17. The second gear 20, connected to the second gear 20, is connected to the second synchronous pulley 23 via the synchronous belt 22, thereby rotating the second cleaning roller 18. In this way, the first cleaning roller 17 and the second cleaning roller 18 rotate simultaneously, cleaning in a rolling manner and improving the cleaning effect.

[0028] Working principle: The system consists of a housing 1, a mounting plate 2, a mesh belt conveyor, a drying device, and a flipping mechanism 9. The flipping mechanism 9 includes a mounting rod 11, a square ring 12, an electric push rod 13, and a bidirectional motor 10. A photoelectric sensor is installed on the inner wall of the housing 1 and is electrically connected to a PLC. The items to be dried are placed on the conveyor belt 3 for transport. The photoelectric sensor detects the object and transmits a signal to the PLC. The PLC controls the bidirectional motor 10 to work, which drives the mounting rod 11 to rotate, thereby flipping the square ring 12 and relative turning the moving object. As the object moves, it flips. The continuously operating drying device dries the surface of the object. Through the above design, the object can automatically flip and be dried while moving.

[0029] It should be noted that the mesh belt conveyor mechanism in this solution is existing technology, and its installation and use are both publicly available technologies.
