Technical Field

[0001] The utility model relates to steel ball processing equipment, in particular to a precise quantitative feeding structure for steel balls. Background Art

[0002] During the processing, the steel balls need to be placed in a heat treatment furnace for heat treatment. Since the heat treatment furnace is a spiral conveyor, the existing feeding device cannot accurately control the feeding amount, resulting in the steel balls getting stuck when the feeding amount is too much, and the conveying efficiency is low and the energy consumption is high when the feeding amount is too little. The patent "A Steel Ball Feeding Device" with application number "201921573618.1" is a patent previously applied by our company. The feeding of this equipment can control the feeding amount to a certain extent, but it is still not accurate enough. Summary of the invention

[0013] In the figure: feeding funnel 1, discharge port 2, guide block 3, channel 4, steel ball 5, turntable 6, sealing plate 7, sprocket 8, through hole 9. DETAILED DESCRIPTION

[0014] like Figure 1-2 As shown, a precise quantitative feeding structure for steel balls includes a feeding hopper 1, which is fixed to the ground by legs. A discharge port 2 is provided at the lower end of the feeding hopper 1, and the upper inner wall of the discharge port 2 is threaded, and a guide block 3 is threadedly connected to the threaded section therein to keep it fixed. A plurality of channels 4 are circumferentially provided on the guide block 3, and the channels 4 are arc-shaped, with a feed port at the upper end and a discharge port at the lower end. A turntable 6 is provided in the discharge port 2 below the guide block 3, and the center of the lower end of the turntable 6 is fixedly connected to the rotating shaft, and the bearing at the center of the rotating shaft and the sealing plate 7 can be rotatably connected and extend out of the sealing plate 7, and the sealing plate 7 is fixed at the bottom of the discharge port 2. A sprocket 8 is installed at the bottom end of the rotating shaft, and the sprocket 8, the driving sprocket, and the chain can form a chain transmission mechanism, and the chain transmission mechanism can be driven to rotate by a motor.

[0015] The turntable 6 and the sealing plate 7 are both provided with through holes 9, which penetrate the turntable 6 or the sealing plate 7 from top to bottom. The turntable 6 has only one set of through holes 9, and the through holes 9 of the turntable 6 can be directly opposite to the discharge port of the channel 4 or directly opposite to the through holes 9 on the sealing plate 7 during the rotation process; and the number of through holes 9 on the sealing plate 7 matches the number of channels 4 and is staggered with the discharge port of the channel 4.

[0016] The through hole 9 of the rotating disk 6 only accommodates one steel ball 5. This ensures quantitative control.

[0017] The channels 4 are at least two groups, and can be two groups, three groups or four groups.

[0018] A vibration motor is arranged at the lower end of the material discharge hopper 1. The vibration of the vibration motor helps discharge the material.

[0019] Working principle and process:

[0020] 1) When the channels 4 are divided into two groups and arranged left and right on the guide block 3 , the through holes 9 on the sealing plate 7 are divided into two groups and arranged front and back on the sealing plate 7 .

[0021] 2) The turntable 6 rotates under the action of the driving device. First, the through hole 9 of the turntable 6 faces the channel 4 on the left. A steel ball in the channel 4 on the left falls into the through hole 9 of the turntable 6. Figure 1 After the turntable 6 rotates 90 degrees, the through hole 9 of the turntable 6 is opposite to the through hole 9 on the rear side of the sealing plate 7, and the steel ball falls from the through hole 9 of the turntable 6 to the through hole 9 on the rear side of the sealing plate 7 and falls down, and can fall on the slide, and finally pass through the slide into the furnace, as shown in FIG. Figure 2 shown.

[0022] 3) After the turntable 6 continues to rotate 90 degrees, the through hole 9 of the turntable 6 faces the channel 4 on the right, and a steel ball in the channel 4 on the right falls into the through hole 9 of the turntable 6. After the turntable 6 continues to rotate 90 degrees, the through hole 9 of the turntable 6 faces the through hole 9 on the front side of the sealing plate 7, and the steel ball falls from the through hole 9 of the turntable 6 into the through hole 9 on the front side of the sealing plate 7 and falls down, and can fall onto the slide, and finally enter the furnace through the slide.

[0023] In this way, the turntable 6 rotates one circle, and two steel balls fall. The material feeding speed can be adjusted by controlling the rotating speed of the turntable 6, and then matched with the conveying speed and conveying capacity of the heat treatment furnace.
