[0019] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0020] This specific embodiment describes in detail the O-ring feeding mechanism with clearing function described in this application, such as Figure 1-Figure 3 As shown, the O-ring feeding mechanism with a clearing function includes: a bottom plate 1, a silo 2, an air source, a feeding seat and a blocking block. The silo 2 is fixed to the bottom plate 1. The silo 2 can accommodate an O-ring 20. The bottom of the silo 2 is provided with an upper blowing hole 3. There are more than one side blowing holes 4 spaced around the side wall of the silo 2. The feeding seat is fixed to the side wall of the silo 2. A flow channel 5 is provided in the feeding seat. The side wall of the silo 2 is provided with an opening for the feeding seat to extend into. The first end of the flow channel 5 is located inside the silo 2. The second end of the flow channel 5 is connected to a feeding trough 7 provided on the feeding seat. The upper end of the feeding trough 7 is open. A back-blowing air hole 6 is provided near the second end of the flow channel 5, and the upper blowing air hole 3, the side blowing air hole 4 and the back-blowing air hole 6 are all connected to the air source. The O-ring 20 in the silo 2 can roll up and down under the blowing of the upper blowing air hole, and the O-ring 20 rolling up and down can move along the inner wall of the silo 2 under the blowing of the side blowing air hole 4. The O-ring 20 moving along the inner wall of the silo 2 can enter the first end of the flow channel 5 and move along the flow channel 5 to the feed trough 7. The block can be stuck at the second end of the flow channel and sealed with the second end of the flow channel. The O-ring 20 located in the flow channel 5 can move into the silo 2 under the blowing of the back-blowing air hole 6. When in use, first put multiple O-rings 20 into the silo 2, and then the O-rings 20 in the silo 2 roll up and down in the silo 2 under the blowing of the upper blowing hole 3, and then the O-rings 20 rolling up and down in the silo 2 move circumferentially along the inner wall of the silo 2 under the blowing of the side blowing hole 6. When the moving path of any O-ring 20 moving along the inner wall of the silo 2 overlaps with the first end of the flow channel 5, the O-ring 20 moving along the inner wall of the silo 2 can enter the first end of the flow channel 5. It should be noted that in actual use, not all moving paths of the O-rings 20 moving along the inner wall of the silo 2 overlap with the first end of the flow channel 5. The larger the opening at one end, the greater the probability that the O-ring 20 enters the first end of the flow channel 5. The user can select the size of the opening at the first end of the flow channel 5 according to production requirements to better adapt to production requirements. The O-ring 20 entering the first end of the flow channel 5 can move along the flow channel 5 to the feed trough 7 to realize feeding. When the O-ring 20 in the flow channel 5 blocks the flow channel 5, first close the upper blowing hole 3 and the side blowing hole 4, and then use a block to block the second end of the flow channel 5. At this time, start the back-blowing hole 6 to blow the O-ring 20 blocked in the flow channel 5 back into the silo 2. Since the O-ring 20 blocking the flow channel 5 can be cleaned without disassembling the equipment, the clearing efficiency is high. It has the advantage of high clearing efficiency. In some optional embodiments, the silo 2 is also provided with a vent valve that can be manually switched on and off for balancing the air pressure.

[0021] Optionally, this embodiment further includes a connecting seat 8, a linear moving mechanism 9 and a cover plate 10. The connecting seat 8 is fixed to the side of the feeding seat away from the silo 2, the linear moving mechanism 9 is fixed to the top surface of the connecting plate, and the cover plate 10 is fixed to the moving end of the linear moving mechanism 9. The cover plate 10 is provided with a clearance gap 11 at one end close to the feeding trough 7. The width of the clearance gap 11 is smaller than the outer diameter of the O-ring 20. The cover plate 10 can be covered on the feeding trough 7 under the drive of the linear moving mechanism 9. When the cover plate 10 is covered on the feeding trough 7, the clearance gap 11 is located directly above the O-ring 20 that moves to the feeding trough 7. The pin can be inserted into the clearance gap 11 and then inserted into the inner ring of the O-ring 20 located at the feeding trough 7. When taking materials, the cover plate 10 is first covered on the feed trough 7 under the drive of the linear motion mechanism 9. At this time, the cover plate 10 can prevent the O-ring 20 from leaving the feed trough 7. Then the pin is inserted into the clearance gap 11 and inserted into the inner ring of the O-ring 20. The O-ring 20 is fixed by friction. Then the cover plate 10 is driven away from the feed trough 7 by the linear motion mechanism 9. At this time, the pin can take the O-ring 20 out of the feed trough 7.

[0022] In this embodiment, a clearance hole 12 is optionally provided below the feed slot 7. The end of the insertion pin can be inserted into the clearance hole 12 after being inserted into the inner ring of the O-ring 20 located at the feed slot 7. The blocking block is made of rubber material. The clearance hole 12 facilitates the insertion of the pin into the O-ring 20.

[0023] Optionally, in this embodiment, the linear motion mechanism 9 is a slide cylinder.

[0024] Optionally, this embodiment further includes a first solenoid valve 13, a second solenoid valve 14 and a third solenoid valve 15. The first solenoid valve 13, the second solenoid valve 14 and the third solenoid valve 15 are all fixed on the top surface of the bottom plate 1. The number of upper blowing holes 3 is greater than one and is spaced apart at the bottom of the silo 2. The upper blowing holes 3 are connected to the first solenoid valve 13 through a first air pipe, the side blowing holes 4 are connected to the second solenoid valve 14 through a second air pipe, the back blowing holes 6 are connected to the third solenoid valve 15 through a third air pipe, the first solenoid valve 13 is connected to the air source through a fourth air pipe, the second solenoid valve 14 is connected to the air source through a fifth air pipe, and the third solenoid valve 15 is connected to the air source through a sixth air pipe.

[0025] This embodiment optionally further includes a feed cover 16. A feed opening is provided at the top of the silo 2. The feed cover 16 is detachably fixed to the top of the silo 2 by a first bolt and covers the feed opening. An observation window made of a transparent material is provided in the middle of the feed cover 16. The observation window allows a user to easily observe whether the O-ring 20 in the silo 2 is exhausted.

[0026] In this embodiment, the feed base optionally includes a feed plate 17 and an upper cover 18. The top surface of the feed plate 17 is provided with an arcuate notch, and the feed trough 7 is provided on the top surface of the feed plate 17. The upper cover 18 is removably fixed to the top surface of the feed plate 17 by a second bolt. The flow channel 5 is formed by the arcuate notch and the bottom surface of the upper cover 18. In this way, if it is not appropriate to use the back-blowing air hole 6 for clearing a blockage, such as if debris has entered the flow channel 5, the upper cover 18 can be removed to expose the arcuate notch, which can then be easily cleaned by the user.

[0027] In this embodiment, optionally, a blocking protrusion 19 is provided on the side wall of the feed plate 17. The blocking protrusion 19 is provided next to the first end of the flow channel 5 and extends into the silo 2. A guide surface is provided on the side wall of the blocking protrusion 19 close to the flow channel 5. The first end of the flow channel 5 is flush with the inner side wall of the silo 2. The guide surface is connected to the side wall of the first end of the flow channel 5. The O-ring 20 moving along the inner side wall of the silo 2 can enter the first end of the flow channel 5 along the guide surface after contacting the guide surface. Both side walls of the flow channel 5 are provided with positioning grooves for the outer wall of the O-ring 20 to be inserted. The positioning grooves on the two side walls of the flow channel 5 can ensure that the O-ring 20 moves in the flow channel with the correct posture, can prevent the O-ring 20 from rolling in the flow channel 5, and can reduce the probability of the O-ring 20 blocking the flow channel 5.

[0028] In this embodiment, optionally, there are two back-blowing holes 6, one of which is provided on the bottom wall of the arc-shaped slot near the second end of the flow channel 5, and the other is provided on the bottom wall of the arc-shaped slot in the middle of the flow channel 5. Providing two back-blowing holes 6 and blowing air through the two back-blowing holes 6 simultaneously can further improve the blockage clearing capability.
