[0027] Reference Figure 1 , Figure 2 , Figure 3 Feeding assembly includes the transmission belt 10 setting in the inside of installation shell 4, the one side of transmission belt 10 is provided with micro motor 11, the top of transmission belt 10 is provided with fixed plate 12 on the surface of installation shell 4, the one side of fixed plate 12 is provided with return spring 13, the one end of return spring 13 is provided with sliding block 14, sliding block 14 is fixedly connected with baffle 6, the bottom of baffle 6 is provided with lug 15, lug 15 abuts with knob 5, feeding assembly still includes the vertical cavity 16 setting in the top of transmission belt 10, and the vertical cavity 16 is communicated with the inside of installation shell 4, and the top of vertical cavity 16 is fixedly connected with feeding pipe 7, and the bottom of vertical cavity 16 is blocked by baffle 6.

[0028] In the scheme, the surface of loading tray 3 is provided with a plurality of material ports, the material conveying pipe 8 corresponds with the material port, the inside of installation shell 4 has irregular cavity, can make knob 5 rotate in irregular cavity, baffle 6 abuts at one end of dredging plate 9, blocks vertical cavity 16, can prevent spring in vertical cavity 16 from falling on transmission belt 10, and the slideable dredging plate 9 is arranged at one side of vertical cavity 16, and the connecting place of dredging plate 9 and installation shell 4 is provided with buckle, which is prior art, and this paper does not elaborate too much, and the main function is to clamp dredging plate 9, to prevent dredging plate 9 from falling.

[0029] The width of transmission belt 10 is less than the diameter of spring, and knob 5 is attached to one side of transmission belt 10, so that knob 5 can drive the spring transmitted by transmission belt 10, while knob 5 rotates to drive the spring, knob 5 also drives the lug 15 above, so that the lug 15 drives the baffle 6 to slide, at this time, the sliding block 14 at the top of the baffle 6 and the lug 15 extrude the return spring 13, the baffle 6 moves away from the bottom of the vertical cavity 16, the spring in the vertical cavity 16 falls onto the transmission belt 10 and is transported by the transmission belt 10 to one side of the knob 5, then the return spring 13 is elongated and pushes the sliding block 14 to move, so that the baffle 6 abuts at one side of the dredging plate 9 and blocks the vertical cavity 16, so as to repeat the above process, so that the spring is intermittently supplied to prevent winding in the installation shell 4.

[0030] ReferenceFigure 5 The outer part of the mounting shell 4 is provided with a driving motor 17, and the output shaft of the driving motor 17 is in transmission connection with the poking piece 5.

[0031] With reference to Figure 4 The leakage-proof assembly comprises a rubber ring 18 arranged in the inside of the material conveying pipe 8, and the outer part of the rubber ring 18 is provided with a plurality of limiting blocks 19. The top of the mounting shell 4 is provided with a pneumatic cylinder 20, and the output end of the pneumatic cylinder 20 is provided with a pressing block 21 which is arranged in correspondence with the material conveying pipe 8.

[0032] In this scheme, the limiting blocks 19 and the rubber ring 18 are arranged, which reduces the diameter of the material conveying pipe 8, blocks the discharge of the spring, and prevents the spring from falling out before the material conveying pipe 8 moves to the material port. When moving to the material port, the pneumatic cylinder 20 is started, the output end of the pneumatic cylinder 20 is elongated to push the pressing block 21, the pressing block 21 pushes the spring, so that the spring extrudes the limiting block 19, the limiting block 19 extrudes the rubber ring 18, so that the rubber ring 18 is extruded inward to increase the diameter, and finally the spring enters the material port through the limiting block 19.

[0033] With reference to Figure 5 The outer part of the mounting shell 4 is provided with a sensor 22.

[0034] In this scheme, the sensor 22 is a prior art, which will not be described in detail herein. The main function is to assist the positioning of the material conveying pipe 8 at the bottom of the mounting shell 4, and to complete the precise feeding.

[0035] With reference to Figure 1 One end of the feeding pipe 7 is provided with a vibrating feeder 23 on the bottom end face of the spring grinding machine body 1.

[0036] In this scheme, the vibrating feeder 23 is a prior art, and the main function is to vibrate and screen the spring to provide the spring for the feeding pipe 7.

[0037] With reference to Figure 1 The bottom of the loading disc 3 is provided with a stepping motor 24, and the end face of the rotating disc is provided with a rotating shaft 25. The stepping motor 24 is in transmission connection with the rotating shaft 25, and the surface of the rotating shaft 25 is provided with a connecting seat 26 which is connected with the mounting shell 4.

[0038] When in use, the spring will enter into the vertical cavity 16 along the feeding pipe 7 and be blocked by the baffle 6. When the knob 5 rotates, the spring on the conveying belt 10 will pass through and enter into the feeding pipe 8. When the knob 5 rotates, the knob 5 will push the protruding block 15, so that the protruding block 15 drives the baffle 6, the slider 14 at the top of the baffle 6 moves towards the fixed block and presses the return spring 13. After the baffle 6 moves, the spring at the top of the baffle 6 falls onto the surface of the conveying belt 10. Then the return spring 13 is elongated and pushes the baffle 6 at the bottom of the slider 14 to move, until the baffle 6 abuts against one side of the dredging plate 9, and blocks the spring in the vertical cavity 16 again. The above process is repeated to form intermittent feeding.

[0039] The spring on the conveying belt 10 will enter into the feeding pipe 8 and be blocked by the limiting block 19, so as to prevent the spring from falling off when the feeding pipe 8 is not positioned accurately. After the feeding pipe 8 is positioned accurately, the output end of the air cylinder 20 is elongated to push the extrusion block 21, the extrusion block 21 pushes the spring, so that the spring extrudes the limiting block 19, the limiting block 19 extrudes the rubber ring 18, so that the rubber ring 18 is shortened, and finally the spring passes through the limiting block 19 and enters into the material port to complete the feeding.

[0040] When the spring is stuck, the staff needs to push down the dredging plate 9 at one side of the vertical cavity 16, take out the stuck spring in the vertical cavity 16 or the mounting shell 4, and slide the dredging plate 9 upwards to be clamped at one side of the mounting shell 4 to complete dredging and reduce the maintenance time.
