[0035] Reference Figure 1 and Figure 5The left end of the conveying bracket 5 is provided with an adjusting component 6 for adjusting the unloading position of the conveyor belt 4. The adjusting component 6 includes an adjusting block 63 for driving the baffle 62 to move left and right. The adjusting block 63 passes through and slides on the left end of the conveying bracket 5. The right end of the adjusting block 63 is fixedly connected with a baffle 62 for blocking the nut. The unloading position of the conveyor belt 4 can be adjusted by adjusting the position of the baffle 62. The top of the conveying bracket 5 is fixedly connected with a limit plate 61 for limiting the moving trajectory of the baffle 62. The top of the baffle 62 is slidably connected to the inner wall of the limit plate 61. The limit plate 61 can limit the adjustment range of the baffle 62, and at the same time can also support the baffle 62 to make it move stably.

[0036] Reference Figure 1 and Figure 5 The left end of the baffle plate 62 is fixedly connected with a return spring 64 for driving the baffle plate 62 to move rightward and return to its original position. The left end of the return spring 64 is fixedly connected to the right end of the conveying bracket 5. When the adjusting block 63 is not fixed, the return spring 64 will push the baffle plate 62 to move rightward until it reaches the rightmost end of the inner wall of the limit plate 61. The left end of the conveying bracket 5 is fixedly connected with a fixing box 67 for accommodating the card block 65. The rear end of the fixing box 67 is slidably connected with the card block 65 for fixing the adjusting block 63. The rear end of the card block 65 is fixedly connected with an adjusting spring 66 for preventing the card block 65 from moving at will. The rear end of the adjusting spring 66 is fixedly connected to the inner wall of the fixing box 67. The rear end of the adjusting block 63 is provided with an adjusting groove 68 for accommodating the card block 65. The adjusting groove 68 is adapted to the card block 65. When the card block 65 is inserted into the adjusting groove 68, the adjusting block 63 will be fixed and cannot move left or right.

[0037] Working principle: When in use, when performing nut quenching operation, the nut needs to be put into the quenching box 1 from the feed port 2, and the nut will move downward along the top of the rotating slide rail 7. When the nut moves to the top of the fixed plate 12, it will be blocked by the protrusion 13 and cannot move further. During the rotation of the rotating block 96, the first nut at the top of the fixed plate 12 will be lifted and driven to rotate synchronously. As the rotating shaft 94 continues to rotate, when the receiving groove 95 corresponds to the upper opening 92, the nut will pass through the upper opening 92 and enter the interior of the receiving groove 95. As the rotating shaft 94 continues to rotate When the rotating block 96 is docked with the top of the rotating slide rail 8, the receiving groove 95 will be aligned with the lower opening 93, and the nut will pass through the lower opening 93 under the influence of gravity to leave the inside of the receiving groove 95 and reach the top of the rotating slide rail 8. In this process, the nut will be flipped, which can ensure that the nut is heated evenly when moving inside the quenching box 1. As the nut continues to move, it will fall to the top of the unloading plate 10, and slide downward along the top of the unloading plate 10, leave the quenching box 1 at the discharge port 3, and fall to the top of the conveyor belt 4, and the conveyor belt 4 will drive the nut to move to the next step.

[0038] When it is necessary to adjust the nut landing point, the block 65 can be pushed backward first to move it backward and away from the inside of the adjustment slot 68. At this time, the return spring 64 will push the baffle 62 to move to the right until it reaches the rightmost end of the inside of the limit plate 61. Then the operator can drive the baffle 62 to move left and right by moving the adjustment block 63. When it is adjusted to the required position, the block 65 can be released to make the adjustment spring 66 push the block 65 to move backward and re-engage the inside of the adjustment slot 68. At this time, the adjustment block 63 will be re-fixed.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
