A shaft 36 is provided in the roller groove 39. A roller 37 is installed on the shaft 36. A roller groove 33 is opened on the right side of the connecting rod 38. A shaft 34 is provided in the roller groove 33. A roller 32 is installed on the shaft 34. The wheel surfaces of the roller 32 and the roller 37 are grooved. A track 31 is installed on them. A track brush 35 is provided between the track 31 and the inside of the roller groove 33.

[0034] The water pipe 10 installed on the water tank 12 is L-shaped, and the water pipe 10 is equipped with a water collection pipe 11. The water collection pipe 11 is composed of a left U-shaped pipe 111 and a right U-shaped pipe 112. Fifteen water collection pipes 11 are installed on each water pipe 10, and the outlet of every three water collection pipes 11 is directly opposite the groove 23 on the conveyor roller 20.

[0035] The water tank 12 is connected to the right side of the fixing plate 2 80. A water passage groove 13 is opened on the water tank 12. A water passage groove 82 is opened at the bottom of the fixing plate 2 80. The water passage groove 13 is connected to the water passage groove 82.

[0036] A fixing rod 83 is fixedly installed at the round hole 81 on the right side of the fixing plate 2 80. The rotary transmission device 30 is connected to the fixing plate 2 80 through the fixing rod 83 and is fixedly installed on the fixing plate 2 80.

[0037] A motor 14 is installed on the water tank 12. The motor 14 is connected to a shaft 34, which in turn connects to the rollers 32 of all the rotary transmission devices 30.

[0038] Both roller 32 and roller 37 have concave surfaces that are lower in the middle and higher on both sides, allowing the track 31 to fit stably without slipping.

[0039] In use, the initial position of the track opening 21 on the conveyor roller 20 is first adjusted to achieve the desired rotational dwell time. During this process, a second motor 40 is installed on the motor platform 50, and the second motor 40 is connected to the conveyor roller 20 through a third shaft 41. A first motor 14 is installed on the water tank 12, and the first motor 14 is connected to a first shaft 34. The first shaft 34 is connected to the first roller 32 of all the rotary transmission devices 30. By controlling the rotation pattern of the first motor 14 and the second motor 40, the rotation control of the conveyor roller 20 and the track 31 can be achieved to reach the required bar rotational dwell time.

[0040] The water pump is started, allowing cooling water to flow from the water collection pipe 11 to the surface of the bar, thus cooling the bar. During this process, the water pipe 10 installed on the water tank 12 is L-shaped, and the water collection pipe 11 is installed on the water pipe 10. The water collection pipe 11 consists of a left U-shaped pipe 111 and a right U-shaped pipe 112. Each water pipe 10 has fifteen water collection pipes 11 installed. The outlet of every three water collection pipes 11 is directly opposite the groove 23 on the conveyor roller 20. The water pump is started, allowing cooling water to flow from the water tank 12 through the water pipe 10 to the water collection pipe 11. The water then flows out from the left U-shaped pipe 111 and the right U-shaped pipe 112 of the water collection pipe 11 onto the bar at the groove 23 of the conveyor roller 20, absorbing and carrying away the heat from the bar.

[0041] During the cooling process of the bar stock on the conveyor roller 20, a row of motors 40 on the motor platform 50 drives the conveyor roller 20 to rotate via shaft 41. The bar stock is driven on the conveyor roller 20. The transmission speed of the bar stock can be controlled by adjusting the motors 40. When the track opening 21 on the groove 23 rotates to the surface of the bar stock, the motor 14 drives the roller 32 to rotate via shaft 34. The rotation of the roller 32 drives the track 31 and the roller 37 to move. The track 31 contacts the surface of the bar stock through the track opening 21 and drives the bar stock to rotate. The rotation of the bar stock allows the cooling water to be sprayed to all parts of the bar stock surface and achieve uniform cooling.

[0042] When the track 31 rotates, the rotary transmission device 30 has a connecting rod 38. A roller groove 39 is opened on the left side of the connecting rod 38. The roller groove 39 is located in the roller chamber 22. A shaft 36 is provided in the roller groove 39. A roller 37 is installed on the shaft 36. A roller groove 33 is opened on the right side of the connecting rod 38. A shaft 34 is provided in the roller groove 33. A roller 32 is installed on the shaft 34. The surfaces of the roller 32 and the roller 37 are concave. The track 31 is installed on them. A track brush 35 is provided between the track 31 and the inside of the roller groove 33. The track 31 can brush the residue on its surface into the water channel 13 on the water tank 12 through the track brush 35. The residue is then collected in the water collection tank 70 along with the sprayed cooling water through the water channel 82. After being cooled, the bar is conveyed out through the conveyor roller 20.
