[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] A valve core feeding mechanism, such as Figure 1-Figure 6 As shown, it includes a bracket 1, a guide tube 2, a discharge assembly 3, a diameter measuring assembly 4 and a dividing assembly 5. The guide tube 2 is tiltedly arranged on the bracket 1. The feed end of the guide tube 2 is connected to the grinding equipment, and the discharge end is sequentially connected to the diameter measuring assembly 4 and the dividing assembly 5. The discharge assembly 3 is arranged on the guide tube 2, and the valve cores are discharged one by one by the discharge assembly 3; wherein the guide tube 2 plays the role of temporarily storing the valve core and guiding the valve core to move so as to guide it into the diameter measuring assembly 4. The valve cores are measured one by one by the diameter measuring assembly 4; and the dividing assembly 5 is selectively stored according to the detection structure, that is, qualified valve cores are guided into qualified storage boxes, and unqualified valve cores are guided into unqualified storage boxes.

[0022] In one embodiment, if Figure 1-Figure 6As shown, the discharge assembly 3 includes a first cylinder 31, a second cylinder 32, a first stopper 33 and a pressure block 34. An opening is provided on the material guide pipe 2, and the pressure block 34 is provided above the opening. The first cylinder 31 is installed above the material guide pipe 2 through a fixing frame, and the pressure block 34 is connected to the first cylinder 31. The pressure block 34 is controlled by the first cylinder 31 to pass through the opening on the material guide pipe 2 to temporarily fix the valve core in a pressing manner; the first stopper 33 is provided at the discharge end of the material guide pipe 2, and the first stopper 33 is connected to the second cylinder 32. The first stopper 33 is controlled to move up and down by the second cylinder 32, thereby controlling the opening and closing of the discharge end of the material guide pipe 2. Specifically, the distance between the pressing block 34 and the first stopper 33 is greater than the length of one valve core and less than the length of two valve cores; when in use, the outlet end of the material guide pipe is closed by the first stopper 33, the valve cores are arranged in sequence, the valve core arranged in the second position is pressed and fixed by the pressing block 34, and then the first stopper 33 is controlled to open by the second cylinder 32, and a valve core slides out along the material guide pipe 2 into the diameter measurement component 4. Then the material outlet end of the material guide pipe 2 is closed again by the first stopper 33, and the above actions are repeated to realize the discharge of the valve cores one by one.

[0023] In the above embodiment, if Figure 1-Figure 6 As shown, the discharge assembly 3 also includes two groups of proximity switches 35, which are respectively installed on one side of the pressing block 34 close to the feeding end of the material guide tube 2 and between the pressing block 34 and the first stopper 33; and an opening is set at the corresponding position of the material guide tube 2, and the proximity switch 35 is used to detect whether there is a valve core in the material guide tube 2. Specifically, the proximity switch 35 located between the pressing block 34 and the first stopper 33 is used to detect the valve core arranged in the first position to determine whether the valve core is discharged; if the proximity switch does not detect the valve core, the material discharge procedure of the next valve core is entered; if the proximity switch can detect the valve core, the valve core is waited for to be discharged. The proximity switch 35 located on the pressing block 34 close to the material guide tube 2 is used to detect whether there is a valve core in the material guide tube 2. If the proximity switch detects the valve core, it indicates that the pressing block 34 can perform a clamping action to clamp and fix the valve core arranged in the second position.

[0024] In one embodiment, if Figure 1-Figure 6 As shown, an anti-jamming component 6 is also included, and the anti-jamming component 6 is used to knock the material guide tube 2. Because grinding fluid is used during grinding, it is inevitable that some grinding fluid will remain after the processing is completed, and the presence of this fluid may cause the valve core to be unable to smoothly pass through the material guide tube 2. By setting the anti-jamming component 6, the material guide tube 2 is continuously knocked, which can promote the passage of the valve core.

[0025] In the above embodiment, if Figure 1-Figure 6 As shown, the anti-jamming assembly 6 includes a hammer head 61 and a third cylinder 62 . The third cylinder 62 is used to control the hammer head 61 to move back and forth to strike the outer wall of the material guiding tube 2 .

[0026] In one embodiment, if Figure 1-Figure 6 As shown, the diameter measuring assembly 4 includes a measuring tube 41, a sensor 42, a second stopper 43 and a fourth cylinder 44. The measuring tube 41 is arranged at the extension of the guide tube 2. An opening is arranged on the side of the measuring tube 41. The diameter of the valve core is measured through the opening by the sensor 42. The second stopper 43 is arranged at the outlet end of the measuring tube 41. The fourth cylinder 44 is connected to the second stopper 43. The fourth cylinder 44 drives the second stopper 43 to control the opening and closing of the measuring tube. When in use, the valve core is supported by the second stopper 43, and the sensor 42 detects the size of the valve core. After the detection is completed, the fourth cylinder 44 is controlled to control the second stopper to open, and the valve core enters the material distribution assembly 5 to control the movement of the material distribution assembly 5 according to the detection result.

[0027] In one embodiment, if Figure 1-Figure 6 As shown, the material distribution component 5 includes two material distribution pipes 51, a temporary storage pipe 52, a third stopper 53, a fifth cylinder 54 and a sixth cylinder 55. The fifth cylinder 54 is fixed on the bracket, and the temporary storage pipe 52 is installed on the fifth cylinder 54. The initial position of the temporary storage pipe 52 is located at the extension of the discharge port of the diameter measurement component 4. The temporary storage pipe 52 is controlled by the fifth cylinder 54 to move horizontally to switch between the two material distribution pipes 51, and the two material distribution pipes 51 are respectively connected to the qualified storage box and the unqualified storage box; an opening is set on the temporary storage pipe 52, and the third stopper 53 is controlled by the sixth cylinder 55 to control the opening and closing of the temporary storage pipe 52. Preferably, when the temporary storage pipe 52 is in the initial position, the discharge end of the temporary storage pipe 52 is connected to the material distribution pipe 51 that guides into the qualified storage box; when the measured size is within the qualified range, the sixth cylinder 55 controls the third stopper 53 to open the temporary storage pipe 52. If the test result is unqualified, the temporary storage tube 52 is driven by the fifth cylinder 54 to move horizontally to another material distribution tube 51 so that it is connected to the unqualified storage box. After it is in place, the third stopper 53 is opened to drop the unqualified valve core into the unqualified storage box through the material distribution tube 51.

If the present invention is modified or replaced by equivalents without departing from the spirit and scope of the present invention, they should be included in the scope of protection of the claims of the present invention.
