One end of the fixing plate 4 is provided with a fixing rod 5, and both sides of the surface of the fixing rod 5 are provided with fixing sleeves 6. A plurality of stirring rods 7 are arranged on the fixing sleeves 6. A plurality of arc-shaped pieces one 8 are arranged on the inner wall of the inner furnace body 1. An arc-shaped piece two 9 is arranged on one side of the arc-shaped piece one 8, and both ends between the arc-shaped piece two 9 and the arc-shaped piece one 8 are connected by a connecting rod 10.

[0022] Specifically, both between the arc-shaped piece one 8 and the inner furnace body 1 and between the fixing sleeve 6 and the fixing rod 5 are welded by spot welding, and one side edge of one end of the arc-shaped piece one 8 is closely attached to the inner wall of the inner furnace body 1.

[0023] By adopting the above technical solutions, spot welding makes the connection between the arc-shaped piece one 8 and the inner furnace body 1 and between the fixing sleeve 6 and the fixing rod 5 more firm, and one side edge of one end of the arc-shaped piece one 8 fits more closely to the inner wall of the inner furnace body 1.

[0024] Specifically, the angle between adjacent arc-shaped pieces one 8 is 90 degrees. The stirring rod 7 and the fixing sleeve 6 are of a welded integral structure. Both between the fixing frame 3 and the inner furnace body 1 and between the fixing frame 3 and the fixing plate 4 are welded by pressure welding.

[0025] By adopting the above technical solutions, a plurality of arc-shaped pieces one 8 can be equidistantly distributed, and pressure welding makes the connection between the fixing frame 3 and the inner furnace body 1 and between the fixing frame 3 and the fixing plate 4 more firm.

[0026] When this embodiment is in use, when the inner furnace blade structure of the coffee roaster is in use, the device is installed at a suitable position. By setting the arc-shaped piece one 8 and the arc-shaped piece two 9, after the coffee beans are put into the inner furnace body 1, the inner furnace body 1 is driven to rotate by a driving mechanism. When the inner furnace body 1 rotates, the coffee beans are blocked by the arc-shaped piece one 8, the arc-shaped piece two 9 and the stirring rod 7 and are stirred inside the inner furnace body 1. When discharging, the inner furnace body 1 continues to rotate, and the receiving box is placed in front of the inner furnace body 1. Guided by the arc-shaped piece one 8, the coffee beans are convenient to discharge. By setting the arc-shaped piece one 8 and the arc-shaped piece two 9, etc., the stirring effect on the coffee beans baked in the inner furnace body 1 is better, and the baking quality of the coffee beans is improved.

[0027] Example 2

[0028] The difference between this embodiment and Embodiment 1 is that a support assembly 2 is arranged outside the inner furnace body 1. The support assembly 2 includes an annular plate 21, fixing ears 22, rotating rollers 23, an annular groove 24, a rubber pad 25, a mounting plate 26 and mounting bolts 27. Among them, an annular plate 21 is arranged outside the inner furnace body 1. A plurality of mounting plates 26 are arranged at both ends of the annular plate 21. Mounting bolts 27 are arranged in the mounting plates 26. Two fixing ears 22 are arranged at the positions corresponding to the annular plate 21 on the inner furnace body 1. A rotating roller 23 is arranged between the two fixing ears 22. An annular groove 24 corresponding to the rotating roller 23 is arranged in the annular plate 21. A rubber pad 25 is arranged on the inner wall of the annular groove 24.

[0029] By adopting the above technical solution, the annular plate 21 is installed and fixed inside the baking machine through the mounting plate 26 and the mounting bolts 27. When the inner furnace body 1 rotates, a plurality of rotating rollers 23 on the inner furnace body 1 roll in the annular groove 24 of the annular plate 21, and the rotating rollers 23 rotate on the fixing ears 22. At the same time, a rubber pad 25 is arranged on the inner wall of the annular groove 24 to reduce the friction noise between the rotating rollers 23 and the annular groove 24. By arranging the support assembly 2, the rotation of the inner furnace body 1 is more stable, avoiding the unstable rotation of the inner furnace body 1 from affecting the service life of the inner furnace body 1 or generating abnormal noises.

[0030] Specifically, the side of the mounting plate 26 is flush with the side of the annular plate 21. Through holes corresponding to the mounting bolts 27 are arranged in the mounting plate 26. The mounting plate 26 and the annular plate 21 are of a welded integral structure.

[0032] Specifically, the rubber pad 25 is adhesively bonded to the annular plate 21 with glue. The adjacent rotating rollers 23 are at an angle of 45 degrees. The rotating rollers 23 and the fixing ears 22 are rotatably connected by a pin.

[0033] By adopting the above technical solution, the glue bonding makes the rubber pad 25 not easy to fall off. A plurality of rotating rollers 23 can be equidistantly distributed, and the rotating rollers 23 can rotate on the fixing ears 22.

[0034] When this embodiment is in use, by setting the support assembly 2, the annular plate 21 is installed and fixed inside the baking machine through the mounting plate 26 and the mounting bolts 27. When the inner furnace body 1 rotates, several rollers 23 on the inner furnace body 1 roll in the annular groove 24 of the annular plate 21, and the rollers 23 rotate on the fixed ears 22. At the same time, a rubber pad 25 is arranged on the inner wall of the annular groove 24 to reduce the friction noise between the rollers 23 and the annular groove 24. By setting the support assembly 2, the rotation of the inner furnace body 1 is more stable, avoiding the unstable rotation of the inner furnace body 1 from affecting the service life of the inner furnace body 1 or generating abnormal noises.

[0035] The working principle and usage process of the present utility model: When the inner furnace blade structure of the coffee roaster is in use, the device is installed in a suitable position. By setting the first arc-shaped piece 8 and the second arc-shaped piece 9, after the coffee beans are placed into the inner furnace body 1, the inner furnace body 1 is driven to rotate by the driving mechanism. When the inner furnace body 1 rotates, the coffee beans are blocked by the first arc-shaped piece 8, the second arc-shaped piece 9 and the stirring rod 7 and stirred inside the inner furnace body 1. When discharging, the inner furnace body 1 continues to rotate, and the receiving box is placed in front of the inner furnace body 1. Guided by the first arc-shaped piece 8, the coffee beans are convenient to discharge. By setting the first arc-shaped piece 8 and the second arc-shaped piece 9, etc., the stirring effect on the coffee beans baked in the inner furnace body 1 is better, improving the baking quality of the coffee beans. By setting the support assembly 2, the annular plate 21 is installed and fixed inside the baking machine through the mounting plate 26 and the mounting bolts 27. When the inner furnace body 1 rotates, several rollers 23 on the inner furnace body 1 roll in the annular groove 24 of the annular plate 21, and the rollers 23 rotate on the fixed ears 22. At the same time, a rubber pad 25 is arranged on the inner wall of the annular groove 24 to reduce the friction noise between the rollers 23 and the annular groove 24. By setting the support assembly 2, the rotation of the inner furnace body 1 is more stable, avoiding the unstable rotation of the inner furnace body 1 from affecting the service life of the inner furnace body 1 or generating abnormal noises.
