[0022] There are four feeding conduits 5, and the four feeding conduits 5 are fixedly arranged at equal intervals on the lower end surface of the support base 1. A one-way guide valve 8 is provided at the side end surface of the feeding conduit 5 near the bottom, and four guide chutes 6 are provided at equal intervals on the inner end surface of the feeding conduit 5;

[0023] The material guiding device 2 is supported on the inner end surface of the card holder 1 and is slidably engaged with the material guiding device 2 through a fixed guide groove 7 .

[0024] The material guiding device 2 includes a limiting slide 22 for support, a fixed slide shaft 21 is fixedly provided at the center of the inner end surface of the limiting slide 22, and four groups of driven gears 28 are equidistantly rotated and clamped near the middle of the inner end surface of the limiting slide 22, the inner end surfaces of the four groups of driven gears 28 are all threadedly connected with threaded sleeves 29, and a threaded guide shaft 25 is fixedly provided on the lower end surface of the threaded guide shaft 25, a spring slide shaft 27 is fixedly provided on the lower end surface of the spring slide shaft 27, and a sealing pressure plate 26 is provided on the lower end surface of the spring slide shaft 27, a stepping motor 23 is provided on the upper end surface of the limiting slide 22 near the driven gear 28, and a driving gear 24 is fixedly provided at the output end of the stepping motor 23.

[0025] The driving gear 24 is meshed with the driven gear 28, which can effectively improve the transmission stability of the equipment.

[0026] The inner end face of the driven gear 28 is provided with a threaded sleeve, and the threaded sleeve is threadedly connected to the threaded sleeve 29. The threaded connection between the threaded sleeve and the threaded sleeve 29 can effectively improve the accuracy of subsequent control of the feeding height of the sealing pressure plate 26 inside the feeding conduit 5.

[0027] The sealing pressure plate 26 is sealed and slidably engaged with the inner end surface of the feeding conduit 5 through the guide groove 6, which can effectively improve the stability of subsequent equipment in adsorbing the flaw detection agent.

[0028] The limiting slide 22 is adapted to the fixed guide groove 7 through the fixed slide shaft 21 and then slidably engaged with the inner end surface of the support card seat 1, which can effectively improve the stability of the subsequent material guiding device 2 sliding up and down inside the support card seat 1, thereby improving the efficiency of the subsequent sealing pressure plate 26 in loading the flaw detection agent.

[0029] Working principle: Before the flaw detection agent is processed, the user can connect the corresponding raw material pipeline with the one-way diversion valve 8 to facilitate the subsequent delivery of various raw materials to the inside of the feeding pipe 5. Then the staff can position the equipment on the upper part of the external mixing equipment. When performing the feeding operation inside the mixing equipment, the volume of the feeding can be precisely regulated first. When regulating, the staff can start the stepper motor 23 at the corresponding raw material. At this time, the stepper motor 23 at the raw material can drive the driven gear 28 at the bottom to rotate. At the same time, the driven gear 28 can be connected to the threaded sleeve 29 through the thread, and then can drive the threaded sleeve 29 and the sealing pressure plate 26 to perform precise up and down displacement inside the feeding pipe 5, thereby regulating the distance between different groups of sealing pressure plates 26 and the bottom of the feeding pipe 5. The initial spacing, at the same time, the guiding device 2 is at the highest point as a whole. When feeding the external mixing equipment, the staff can start the servo motor 3. At this time, the servo motor 3 can drive the fixed guide groove 7 to rotate through the transmission guide roller 4. At the same time, the fixed guide groove 7 can pass through the sliding limit with the fixed slide shaft 21, thereby driving the limit slide 22 and the four groups of sealing pressure plates 26 to move downward synchronously inside the feeding pipe 5. When the sealing pressure plate 26 moves downward, the one-way guide valve 8 is in a closed state. Then the four groups of spring slide shafts 27 can push the sealing pressure plate 26 to the bottom of the feeding pipe 5, thereby completing the feeding operation. When feeding again, the sealing pressure plate 26 is lifted, and the internal pressure of the feeding pipe 5 is negative. At this time, the one-way guide valve 8 is opened, and the raw materials are adsorbed into the feeding pipe 5 for circulating feeding.
