DETAILED DESCRIPTION

[0019] The following is combined with Figure 1-3 This application is described in further detail.

[0020] The present application embodiment discloses an automatic thread rolling machine. Figure 1 , an automatic feeding thread rolling machine, comprising a rectangular device body 1 and two plate-shaped support plates 4, and two thread rolling cylinders 2 are rotatably connected to the side surface of the device body 1, and the two thread rolling cylinders 2 rotate relative to each other to roll the material, and a box-shaped debris box 3 is arranged on the side of the device body 1 below the two thread rolling cylinders 2, and the debris box 3 is used to hold the material debris dropped during thread rolling to avoid affecting the surrounding environment and thread rolling efficiency;

[0021] At the same time, an oblique U-shaped unloading plate 5 is fixedly connected to the upper surfaces of the two supporting plates 4, and a frame-shaped sliding frame 6 is slidably connected to the side surface of the unloading plate 5, and the upper and lower sides of the side surface of the sliding frame 6 are fixedly connected with rod-shaped connecting rods 7, and the opposite side surfaces of the two connecting rods 7 are fixedly connected with plate-shaped baffles 8. When working, a number of materials are placed on the unloading plate 5. Because the bottom surface of the unloading plate 5 is inclined, a number of materials will roll obliquely downward to the baffle 8, and be blocked by the baffle 8 close to the loading box 9. By sliding the sliding frame 6 upward, the two connecting rods 7 and the two baffles 8 are driven to slide upward, and the baffle 8 close to the loading box 9 is moved upward. After sliding, the first material slides down to the loading box 9, and at the same time, the baffle 8 away from the loading box 9 slides upward to block the second material to prevent it from sliding down, and then the sliding frame 6 slides down, causing the two baffles 8 to slide down, and after the baffle 8 away from the loading box 9 slides down, the second material slides down, and at the same time, the baffle 8 close to the loading box 9 slides down to block the second material, thereby completing an automatic unloading of the device, and the side surfaces of the two support plates 4 are located at the lower side of the unloading plate 5 and are fixedly connected to the loading box 9, and the inner wall of the loading box 9 is slidably connected to a plate-shaped pushing plate 10, so that the material can be pushed to the two rolling columns 2 by the sliding of the pushing plate 10 for the rolling operation.

[0022] Reference Figure 2 A groove-shaped second slide groove 16 is opened on the inner side wall of the loading box 9, and the inner side wall of the second slide groove 16 is rotatably connected with a screw rod 17, and the outer surface of the screw rod 17 is screwed and connected with the push plate 10. One end of the second slide groove 16 passes through the loading box 9 to its side surface and is fixedly connected to the output end of the motor so that the screw rod 17 can be driven to rotate by the motor, thereby driving the push plate 10 to slide under the action of the ball screw, thereby completing the automatic loading operation.

[0023] Reference Figure 3A groove-shaped first slide groove 12 is opened on the side surface of the blanking plate 5, a rectangular parallelepiped slider 13 is fixedly connected to the inner wall of the sliding frame 6, and the slider 13 slides relative to the inner wall of the first slide groove 12, and a columnar support column 14 is fixedly connected to the inner wall of the first slide groove 12, and a spring 15 is fixedly connected to the inner top surface of the support column 14, and the lower end of the spring 15 is fixedly connected to the upper surface of the slider 13, and the support column 14 is located inside the spring 15. Secondly, the side surface of the support plate 4 on one side of the blanking plate 5 is rotatably connected with a cam 11 through a rotating shaft, and the rotating shaft passes through the support plate 4 to its side surface and is fixedly connected to the electric The output end of the machine is driven by the motor to drive the cam 11 to rotate, and at the same time, the outer surface of the cam 11 contacts the outer surface of the sliding frame 6. In the process of the proximal point of the cam 11 moving away from the sliding frame 6, the slider 13 slides upward on the inner wall of the first sliding groove 12 due to the limiting effect of the support column 14, thereby driving the sliding frame 6 to slide upward, and the spring 15 is in a compressed state. Subsequently, in the process of the distal point of the cam 11 moving away from the sliding frame 6, the slider 13 and the sliding frame 6 slide downward under the resetting effect of the spring 15, and the lower surface of the sliding frame 6 is always in contact with the outer surface of the cam 11.

[0024] The implementation principle of an automatic feeding thread rolling machine in the embodiment of the present application is as follows: when thread rolling is required, a number of materials are placed on the unloading plate 5. Since the bottom surface of the unloading plate 5 is inclined, a number of materials will roll obliquely downward and be blocked by the baffle 8 close to the loading box 9. Then, the cam 11 is driven by the motor to rotate the rotating shaft. At the same time, the outer surface of the cam 11 contacts the outer surface of the sliding frame 6. In the process that the proximal point of the cam 11 is away from the sliding frame 6, the slider 13 slides upward on the inner wall of the first slide groove 12 due to the limiting action of the support column 14, thereby driving the sliding frame 6 to slide upward, thereby driving the two connecting rods 7 and the two baffles 8 to slide upward. After the baffle 8 close to the loading box 9 slides upward, the first material slides down to the loading box 9, and at the same time, the baffle 8 away from the loading box 9 8 slides upward to block the second material and prevent it from sliding down. Then, when the distal point of the cam 11 is away from the sliding frame 6, the slider 13 and the sliding frame 6 slide downward under the reset action of the spring 15, so that the two baffles 8 slide down. After the baffle 8 away from the loading box 9 slides down, the second material slides down. At the same time, the baffle 8 close to the loading box 9 slides down to block the second material. Then, the screw 17 is driven by the motor to rotate, thereby driving the push plate 10 to slide under the action of the ball screw, thereby pushing the material to the two rolling columns 2, completing the automatic loading of the device and improving the rolling efficiency of the device. Then, the two rolling columns 2 rotate relative to each other to roll the material, and the debris box 3 is used to hold the material debris dropped during rolling to avoid affecting the surrounding environment and rolling efficiency.
