Specific implementation mode

[0019] The technical solutions in the present invention will be further described below in conjunction with the drawings and embodiments.

[0020] As Figures 1 - 3 shown, an automatic feeding mechanism for a thread rolling machine is proposed in an embodiment of the present invention, including:

[0021] Base 1, a set of universal wheels 24 are installed on the lower end surface of the base 1. Through the movement of the universal wheels 24, the staff can easily move the device to a specified position for work. A frustum 2 is fixedly installed on the upper end surface of the base 1, and a storage box 3 is fixedly installed on the upper end surface of the base 1. The storage box 3 matches the workpiece. When the workpiece is poured into the storage box 3 and rolls down along the inclined surface of the storage box 3, there will be no deviation. A pushing component, the pushing component includes a platform 4 fixedly installed on the side wall of the base 1. A protective wall 5 is fixedly installed on the platform 4. A rotating rod 6 is rotatably connected to the protective wall 5. One end of the rotating rod 6 is fixedly installed with a gear wheel 7. Half of the gear wheel 7 has teeth and the other half is smooth. A stabilizing block 8 is installed on the upper end surface of the platform 4. A sliding groove 9 is opened in the stabilizing block 8. A slider 10 is slidably connected in the sliding groove 9. One end of the slider 10 is fixedly installed with a toothed ring 11. The upper and lower ends of the toothed ring 11 have teeth. The toothed ring 11 meshes with the gear wheel 7;

[0022] Through the above structure, when the gear wheel 7 rotates, it only interacts with one end of the toothed ring 11, so a cyclic structure is formed, completing the pushing and resetting work of the toothed ring 11. One end of the toothed ring 11 is fixedly installed with a pushing block 12. The pushing block 12 is circularly installed. The pushing block 12 is slidably connected in the frustum 2. A feeding component is installed on the storage box 3. The feeding component includes two symmetrically arranged fixing blocks 13 installed on the storage box 3. Sliding slots 14 are opened in both fixing blocks 13. Connecting blocks 15 are slidably connected in both sliding slots 14. One end of one of the connecting blocks 15 is threaded through a reciprocating lead screw 16. The reciprocating lead screw 16 is a prior art. The reciprocating lead screw 16 is a lead screw that can make an object move reciprocally without changing the rotation direction of the main shaft. Both ends of the reciprocating lead screw 16 are rotatably connected in the sliding slot 14. One end of the other connecting block 15 is slidably penetrated by a sliding rod 17. Both ends of the sliding rod 17 are fixedly installed in the sliding slot 14. The two connecting blocks 15 are jointly fixedly installed with a blocking block 18;

[0023] The lower end of the blocking block 18 is installed with an inclined surface. When a workpiece rolls out, the installation of the inclined surface can prevent the blocking block 18 from squeezing the subsequent workpieces, resulting in problems in the work process. On the upper end surface of one of the fixing blocks 13, a rotating motor 19 is installed. The rotating motor 19 is a prior art and can make the object connected to its motor shaft rotate. The rotating motor 19 is made of anti-corrosion material. Through the anti-corrosion property of the anti-corrosion material, the damage suffered by the rotating motor 19 can be reduced, and its service life can be extended. The motor shaft of the rotating motor 19 rotates through the fixing block 13 and is fixedly installed at one end of the reciprocating lead screw 16. A belt 20 is rotatably connected to the motor shaft of the rotating motor 19. The other end of the belt 20 is rotatably connected to a rotating rod 21. The other end of the rotating rod 21 is rotatably connected to the platform 4. A first bevel gear 22 is fixedly installed on the rotating rod 21. A second bevel gear 23 is fixedly installed at one end of the rotating rod 6. The first bevel gear 22 meshes with the second bevel gear 23.

[0024] The detailed working process of the present utility model is as follows:

[0025] The staff first moves the device to the feeding port of the rolling machine through the universal wheels 24. Then the staff takes out the workpiece and pours the workpiece into the storage box 3. Since the inside of the storage box 3 matches the workpiece, the workpiece will not shift when rolling on the inclined surface until it is blocked by the blocking block 18. Then the staff turns on the rotating motor 19. The rotating motor 19 drives the reciprocating lead screw 16 to rotate, thereby driving the connecting block 15 to rise and fall cyclically in the sliding groove 14, driving the other connecting block 15 to slide up and down in the sliding groove 14 and the sliding rod 17. At this time, the blocking block 18 is also driven by the connecting block 15 to rise and fall. Its movement amplitude is just enough for a workpiece to roll out. When a workpiece rolls out, the blocking block 18 immediately descends in the cycle and, under the action of the inclined surface at its lower end, avoids squeezing the next workpiece and pushes it back, ensuring the stability of the process. Then the workpiece falls onto the frustum 2. At this time, since a transmission is formed between the belt 20, the rotating motor 19 and the rotating rod 21, when the motor shaft of the rotating motor 19 rotates, it drives the rotating rod 21 to rotate, thereby driving the first bevel gear 22 to rotate, and causing the meshing second bevel gear 23 to rotate, thereby driving the rotating rod 6 to rotate, and causing the gear wheel 7 fixedly connected to the rotating rod 6 to rotate. When the gear wheel 7 rotates, it contacts one end of the toothed ring 11 with teeth and drives the toothed ring 11 to move forward, thereby driving the pushing block 12 to move forward, thereby pushing the workpiece forward on the frustum 2 until it reaches the feeding port of the rolling machine. Then the rotating rod 6 continues to rotate, and the gear wheel 7 rotates to contact the tooth block at the other end of the toothed ring 11 and drives the toothed ring 11 to reset backward, thereby causing the pushing block 12 to reset and perform the next round of pushing work, meeting the use requirements of the staff.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
