Description

Technical Field

[0001] This invention relates to the field of nut processing equipment technology, and more specifically, to a nut guiding mechanism. Background Technology

[0002] When processing nuts, a vibratory feeder is used to arrange the nuts neatly before feeding them. Generally, the vibratory feeder feeds nuts quickly, but the processing speed is slow, especially when machining internal threads. This causes the nuts to continuously feed and fall out of the vibratory feeder, affecting work efficiency. Furthermore, each nut processing device requires a vibratory feeder, which is costly. When feeding nuts via the vibratory feeder, they are usually moved horizontally out of the feeder. However, when processing nuts, they need to be placed vertically. When the nuts are large, if they are guided through an arc-shaped guide channel, they can easily get stuck, thus affecting the processing efficiency. Summary of the Invention

[0003] The purpose of this invention is to solve the problems that each nut processing device requires a vibratory feeder, which is costly, and that nuts are prone to getting stuck during feeding. A nut feeding mechanism and a nut processing device are designed.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows: a nut guiding mechanism includes a transverse guiding channel, one end of which is connected to the discharge end of a vibratory feeder, and a protective plate is installed at the other end of the transverse guiding channel. Multiple inlets and outlets are provided on the transverse guiding channel, with a square opening on one side of each inlet and outlet. A rotating platform is provided on one side of the inlet and outlet, and a fixed platform is provided below the rotating platform.

A servo motor is installed at the upper end of the fixed platform, and the rotating end of the servo motor is connected to the lower end of the rotating platform. Multiple material receiving platforms are rotatably installed on the rotating platform, and each material receiving platform has a material receiving groove. A pushing frame is installed at the inlet and outlet, which can push nuts in the transverse guiding channel into the material receiving groove. The pushing frame can push multiple nuts at a time. A vertical guiding channel is provided on one side of the fixed platform, and the rotating platform can rotate the material receiving platform above the vertical guiding channel. The material receiving groove can guide nuts into the vertical guiding channel.

[0005] Furthermore, the pusher frame includes a pusher platform located on one side of the square opening. A movable plate is provided on one side of the pusher platform. The upper end of the movable plate is connected to the lower surface of multiple pusher platforms. First electric telescopic rods are installed at both ends of the movable plate. The fixed ends of the first electric telescopic rods are installed on a fixed platform. An intercepting plate is provided inside the square opening. A lifting plate is provided above the transverse material guide channel. The lower end of the lifting plate is connected to the upper end of multiple intercepting plates. The two sides of the lower surface of the lifting plate are connected to the upper end of the transverse material guide channel through second electric telescopic rods. The surface of the material holding platform near the transverse material guide channel is an arc-shaped surface. A guide plate is installed at one end of the inlet and outlet.

[0006] Furthermore, four mounting platforms are evenly distributed on the side surface of the rotating platform. A rolling bearing is installed on one side surface of the mounting platform, and a rotating rod is installed inside the rolling bearing. One end of the material receiving platform is installed on the rotating rod, and a transmission frame is installed on the upper end of the fixed platform. The transmission frame can drive the rotating rod to rotate, so that when the material receiving platform rotates to the inlet / outlet side, the material receiving trough is located at the upper end of the material receiving platform. When the material receiving platform rotates to the vertical guide channel side, the material receiving trough rotates to the vertical direction and corresponds to the position of the vertical guide channel. A lifting gate is installed on one side of the material receiving trough on the material receiving platform, and intercepting frames are installed at both ends of the material receiving trough. The lifting gate and the intercepting frames can limit the nut.

[0007] Furthermore, the lifting gate includes a lifting platform located on one side of the material trough. An intercepting block is installed on one side of the lower end of the lifting platform. Guide holes are opened at both ends of the lifting platform, and guide rods are installed in the guide holes. The lower ends of the guide rods are installed on the material trough. The two ends of the lifting platform are connected to the upper end of the material trough through telescopic springs. Lifting rods are installed on both sides of the intercepting plate. When the lifting platform rotates to one side of the intercepting plate, the intercepting plate can lift the lifting platform through the lifting rods.

[0008] Furthermore, the lower end of the interceptor block is provided with an inclined surface.

[0009] Furthermore, the transmission frame includes a ring rack mounted on the upper end of the fixed platform, and a rotating gear mounted on the rotating rod. The lower end of the rotating gear meshes with the ring rack. When the rotating platform rotates, the rotating rod can be driven to rotate through the meshing of the ring rack and the rotating gear.

[0010] Furthermore, the interceptor includes a fixed baffle at one end of the material trough, the lower end of the fixed baffle is installed on the material trough, and an interceptor rod is provided at the other end of the material trough. A first universal ball is installed at one end of the interceptor rod, a limit platform is installed on the outside of the rolling bearing, a limit hole is opened on the rotating gear, one end of the interceptor rod passes through the limit hole and makes one end of the first universal ball rest on the limit platform, a reset plate is installed at one end of the interceptor rod, the reset plate is connected to one side surface of the rotating gear through a reset spring, a limit groove is opened on the limit platform, when the material trough rotates to the top of the vertical guide channel, the first universal ball can enter the limit groove, and an arc-shaped inclined surface is provided on one side of the limit groove on the limit platform.

[0011] Furthermore, a guide groove is provided at the lower end of the limiting groove, and a limiting block is provided in the limiting groove. An adjusting rod is installed at the lower end of the limiting block. The lower end of the adjusting rod passes through the guide groove and extends to the bottom of the limiting platform. A second universal ball is installed at the lower end of the adjusting rod. The lower end of the second universal ball rests on the fixed platform. An adjusting plate is installed on one side of the lower end of the adjusting rod. The adjusting plate and the limiting platform are connected by a compression spring. A fixed groove is provided on one side of the vertical material guide channel and is opened on the fixed platform. When the material holding platform rotates to the top of the vertical material guide channel, the lower end of the adjusting rod can enter the fixed groove. An arc-shaped inclined surface is provided on one side of the fixed groove and is opened on the fixed platform.

[0012] Furthermore, a detection frame is installed on the transverse material guide channel. The detection frame is only installed above the inlet and outlet at the frontmost side of the transverse material guide channel. The detection frame includes a holding plate located above the transverse material guide channel. The holding plate is installed on the transverse material guide channel via a connecting plate. A first photoelectric switch is installed on one side of the lower end of the holding plate. A second photoelectric switch is installed on one side of the first photoelectric switch at the lower end of the holding plate. Two detection holes are opened at the upper end of the transverse material guide channel. The two detection holes are located below the first photoelectric switch and the second photoelectric switch, respectively.

[0013] Furthermore, a vertical guide channel is installed at the input end of the nut processing device.

[0014] The beneficial effects of this invention are as follows: Nuts can be fed into the transverse guide channel by the vibratory feeder and then blocked by the protective plate, allowing the nuts to accumulate in the transverse guide channel. Multiple nuts can be pushed into the holding trough by the pusher frame, and then guided into the vertical guide channel by the rotation of the rotating table and the holding table. This allows one vibratory feeder to drive multiple nut processing devices for processing, and also prevents the nuts from getting stuck. The rotating table and the holding table can also change the opening orientation of the nuts, which makes it easier to place multiple nut processing devices in a shorter transverse guide channel, thus reducing the space occupied.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] In the description of this invention, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, in the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0018] This invention provides, for example Figure 1-12 The nut guiding mechanism shown includes a transverse guiding channel 1, one end of which is connected to the discharge end of a vibratory feeder. A protective plate 2 is installed at the other end of the transverse guiding channel 1. Multiple inlets and outlets 3 are opened on the transverse guiding channel 1. A square opening 4 is provided on one side of each inlet and outlet 3. A rotating platform 5 is provided on one side of each inlet and outlet 3. A fixed platform 6 is located below the rotating platform 5. A support rod 7 is installed at the lower end of the transverse guiding channel 1, and the lower end of the support rod 7 is mounted on the fixed platform 6. A servo motor is installed on the upper end of the fixed platform 6. The rotating end of the servo motor 8 is connected to the lower end of the rotating table 5. Multiple material receiving platforms 9 are rotatably mounted on the rotating table 5. Material receiving platforms 9 have material receiving troughs 10. Pushing frames 11 are installed at the inlet and outlet 3. Pushing frames 11 can push the nuts in the horizontal guide channel 1 into the material receiving troughs 10. Pushing frames 11 can push multiple nuts at a time. A vertical guide channel 12 is provided on one side of the fixed table 6. The rotating table 5 can rotate the material receiving platform 9 above the vertical guide channel 12. The material receiving troughs 10 can guide the nuts into the vertical guide channel 12.

[0019] The process of guiding nuts using this device is as follows: Nuts are fed onto the horizontal guide channel 1 via a vibratory feeder. A protective plate 2 intercepts the end of the horizontal guide channel 1 to prevent nuts from falling. Normally, one receiving platform 9 rotates to the side of the inlet / outlet 3, positioning the receiving trough 10 on the same side. A pusher frame 11 pushes multiple nuts into the receiving trough 10. Then, a servo motor 8 drives the rotating platform 5 to rotate 90 degrees, moving this receiving platform 9 above the vertical guide channel 12. This allows the next receiving platform 9 to rotate to the side of the inlet / outlet 3, continuing to receive nuts. When the rotating platform 5 moves the receiving platform 9 above the vertical guide channel 12... At the same time, the material holding platform 9 can be rotated, and the outlet end of the material holding trough 10 can be rotated to the top of the vertical guide channel 12. Then, under the action of gravity, it can fall into the vertical channel 12, which facilitates the subsequent processing of the nuts. Since there are multiple inlets and outlets 3 and rotating platforms 5 on one side of a horizontal guide channel 1, multiple nuts can be pushed onto the material holding platform 9 on multiple rotating platforms 5 at one time by the push frame 11. Then, the nuts can be moved into the vertical guide channel 12 by the guide mechanism and processed by the nut processing device. This can reduce the number of vibratory feeders used, save energy, prevent the nuts from getting stuck, and facilitate the processing of the nuts.

[0020] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Instruction manual attached Figure 4 Included with instruction manual Figure 5 The pusher frame 11 includes a pusher platform 13 located on one side of the square opening 4. A movable plate 14 is provided on one side of the pusher platform 13. The upper end of the movable plate 14 is connected to the lower surface of multiple pusher platforms 13. First electric telescopic rods 15 are installed at both ends of the movable plate 14. The fixed ends of the first electric telescopic rods 15 are installed on the fixed platform 6. An intercepting plate 16 is provided inside the square opening 4. A lifting plate 17 is provided above the transverse material guide channel 1. The lower end of the lifting plate 17 is connected to the upper end of multiple intercepting plates 16. The two sides of the lower surface of the lifting plate 17 are connected to the upper end of the transverse material guide channel 1 through second electric telescopic rods 18. The surface of the material holding platform 9 near the transverse material guide channel 1 is an arc-shaped surface. A guide plate 19 is installed at one end of the inlet / outlet 3.

[0021] The process of the pusher 11 pushing the nut is as follows: Under normal conditions, one end of the pusher 13 is located at the square opening 4, and the interceptor plate 16 is located at the inlet / outlet 3. The pusher 13 and the interceptor plate 16 can limit the nut to prevent it from leaking out of the transverse feed channel 1. When feeding is required, the second electric telescopic rod 18 is activated to extend. The second electric telescopic rod 18 can drive the lifting plate 17 and the interceptor plate 16 to move upward, thereby opening the inlet / outlet 3. Then, the first electric telescopic rod 15 is activated to shorten. 5. The moving plate 14 can drive the pushing table 13 to move laterally. The pushing table 13 can push the nut into the material trough 10. The guide plate 19 can prevent the nut from falling. When the pushing table 13 pushes the nut, it can also intercept the nut on the rear side. Then, the first electric telescopic rod 15 is activated to extend, which can drive the pushing table 13 back to its original position. The second electric telescopic rod 18 is activated to shorten, which can make the intercepting plate 16 return to its original position. This can facilitate blocking the inlet and outlet 3 and the square opening 4, and then facilitate the nut to continue to move in the transverse guide channel 1.

[0022] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Instruction manual attached Figure 3 Instruction manual attached Figure 4 Instruction manual attached Figure 5 Instruction manual attached Figure 6 Instruction manual attached Figure 7 Instruction manual attached Figure 8 Included with instruction manual Figure 9 Four mounting platforms 20 are evenly distributed on the side surface of the rotating platform 5. A rolling bearing 21 is installed on one side surface of the mounting platform 20. A rotating rod 22 is installed inside the rolling bearing 21. One end of the material holding platform 9 is installed on the rotating rod 22. A transmission frame 23 is installed on the upper end of the fixed platform 6. The transmission frame 23 can drive the rotating rod 22 to rotate. When the material holding platform 9 rotates to the side of the inlet / outlet 3, the material holding trough 10 is located at the upper end of the material holding platform 9. When the material holding platform 9 rotates to the side of the vertical guide channel 12, the material holding trough 10 rotates to the vertical direction and corresponds to the position of the vertical guide channel 12. A lifting gate 24 is installed on the side of the material holding trough 10 and mounted on the material holding platform 9. An intercepting frame 25 is installed at both ends of the material holding trough 10. The lifting gate 24 and the intercepting frame 25 can limit the nut.

[0023] The process of the material receiving platform 9 guiding the nut is as follows: When the material receiving platform 9 is located on one side of the inlet / outlet 3, the lifting gate 24 is opened, which makes it easier for the pusher 11 to push the nut into the material receiving trough 10. Then the lifting gate 24 is closed, and the interceptor 25 can intercept both ends of the material receiving trough 10, thereby preventing the nut from falling. When the rotating platform 5 rotates, the transmission rod 22 can be rotated through the transmission frame 23, which in turn makes the rotating rod 23 and the material receiving platform 9 rotate. When the material receiving platform 9 rotates to the top of the vertical material guiding channel 12, the material receiving trough 10 is placed vertically. Then the interceptor 25 is opened, which makes it easier for the nut to fall into the vertical material guiding channel 12. When the rotating platform 5 continues to drive the material receiving platform 9 to rotate, the outlet end of the material receiving trough 10 can be blocked by the interceptor 25.

[0024] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2 The lifting gate 24 includes a lifting platform 26 located on one side of the material trough 10. An intercepting block 27 is installed on one side of the lower end of the lifting platform 26. Guide holes 28 are opened at both ends of the lifting platform 26. Guide rods 29 are provided in the guide holes 28. The lower ends of the guide rods 29 are installed on the material trough 9. The two ends of the lifting platform 26 are connected to the upper end of the material trough 9 through the telescopic springs 30. Lifting rods 31 are installed on both sides of the intercepting plate 16. When the lifting platform 26 rotates to one side of the intercepting plate 16, the intercepting plate 16 can lift the lifting platform 26 through the lifting rods 31.

[0025] The opening and closing process of the lifting gate 24 is as follows: Under normal conditions, under the tension of the telescopic spring 30, the lifting platform 26 can be pulled downward, and the lower end of the intercepting block 27 can contact the material holding platform 9. The material holding platform 9 can be rotated to the side of the inlet / outlet 3 by the rotating platform 5. When the intercepting plate 16 moves upward, the lifting platform 26 and the intercepting block 27 can be lifted by the lifting rod 31, and the telescopic spring 30 can be stretched. The guide rod 29 and the guide hole 28 can ensure the direction of movement of the lifting platform 26. When the intercepting plate 16 moves downward, the lifting platform 26 and the intercepting block 27 can be pulled back to their original position under the tension of the telescopic spring 30, and the nut can be intercepted.

[0026] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2 The lower end of the intercepting block 27 has an inclined surface. When the intercepting block 27 moves downward, if the nut moves slightly outward and is below the intercepting block 27, the nut can be pushed into the material holding trough 10 through the inclined surface.

[0027] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 3 Included with instruction manual Figure 4The transmission frame 23 includes a ring rack 32 mounted on the upper end of the fixed platform 6, and a rotating gear 33 mounted on the rotating rod 22. The lower end of the rotating gear 33 meshes with the ring rack 32. When the rotating platform 5 rotates, the rotating rod 22 can be driven to rotate through the meshing of the ring rack 32 and the rotating gear 33.

[0028] The process of the transmission frame 23 driving the rotating rod 22 to rotate is as follows: Under normal conditions, the rotating gear 33 meshes with the ring rack 32. Then, when the rotating table 5 drives the rotating rod 22 and the rotating gear 33 to move, the meshing of the rotating gear 33 and the ring rack 32 drives the rotating gear 33 and the rotating rod 22 to rotate.

[0029] Refer to the instruction manual appendix Figure 4 Instruction manual attached Figure 5 Instruction manual attached Figure 7 Instruction manual attached Figure 8 Instruction manual attached Figure 9 Included with instruction manual Figure 11 The interceptor 25 includes a fixed baffle 34 located at one end of the material trough 10. The lower end of the fixed baffle 34 is installed on the material trough 9. The other end of the material trough 10 is provided with an interceptor 35. One end of the interceptor 35 is equipped with a first universal ball bearing 36. A limiting platform 37 is installed on the outside of the rolling bearing 21. A limiting hole 38 is opened on the rotating gear 33. One end of the interceptor 35 passes through the limiting hole 38 and makes one end of the first universal ball bearing 36 press against the limiting platform 37. One end of the interceptor 35 is equipped with a reset plate 39. The reset plate 39 is connected to one side surface of the rotating gear 33 through a reset spring 40. A limiting groove 41 is opened on the limiting platform 37. When the material trough 9 rotates above the vertical guide channel 12, the first universal ball bearing 36 can enter the limiting groove 41. One side of the limiting groove 41 is provided with an arc-shaped inclined surface opened on the limiting platform 37.

[0030] The process of the interceptor 25 intercepting the nut is as follows: The fixed baffle 34 intercepts the nut to prevent it from falling. Under normal conditions, the first universal ball bearing 36 rests on the limiting platform 37. At this time, the interceptor rod 35 is positioned on one side of the nut, thus intercepting the nut and preventing the material receiving platform 9 from falling during rotation. The return spring 40 is in a stretched state. When the material receiving platform 9 rotates above the vertical guide channel 12 and the material receiving trough 10 rotates to a vertical position, the first universal ball bearing 36 moves to the limiting groove 41, and the material receiving platform 9 enters the vertical position. Under the tension of the return spring 40, the intercepting rod 35 can be pulled towards the limiting platform 37, thereby avoiding the nut. The nut can fall into the vertical guide channel 12 under the action of gravity. The limiting block 38 can guide the intercepting rod 35. When the rotating gear 33 drives the intercepting rod 35 to continue rotating, the first universal ball 36 can be pushed under the action of the arc-shaped inclined surface, thereby stretching the return spring 40, so that the intercepting rod 35 can return to its original position, which is convenient for intercepting the nut.

[0031] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 3 Instruction manual attached Figure 4 Included with instruction manual Figure 12 The lower end of the limiting groove 41 has a guide groove 42, and a limiting block 43 is provided in the limiting groove 41. An adjusting rod 44 is installed at the lower end of the limiting block 43. The lower end of the adjusting rod 44 passes through the guide groove 42 and extends to the bottom of the limiting platform 37. A second universal ball bearing 45 is installed at the lower end of the adjusting rod 44. The lower end of the second universal ball bearing 45 rests on the fixed platform 6. An adjusting plate 46 is installed on one side of the lower end of the adjusting rod 44. The adjusting plate 46 and the limiting platform 37 are connected by a compression spring 47. A fixed groove 48 is provided on one side of the vertical material guide channel 12 and is opened on the fixed platform 6. When the material holding platform 9 rotates to the top of the vertical material guide channel 12, the lower end of the adjusting rod 44 can enter the fixed groove 48. An arc-shaped inclined surface is provided on one side of the fixed groove 48 and is opened on the fixed platform 6.

[0032] Under normal conditions, the second universal ball bearing 45 rests on the upper surface of the fixed platform 6, the compression spring 47 is in a compressed state, and the limiting block 43 is located in the limiting groove 41. When the material receiving platform 9 has not rotated above the vertical guide channel 12 and the first universal ball bearing 36 has moved to the limiting groove 41, the limiting block 43 can block the first universal ball bearing 36. At this time, the intercepting rod 35 will not move. When the material receiving platform 9 rotates above the vertical guide channel 12, the second universal ball bearing 45 can move above the fixed groove 48. Then, under the elastic force of the compression spring 47, the adjusting plate 46, the adjusting rod 45, and the first universal ball bearing 45 will move to the upper surface of the fixed groove 48. The second universal ball 45 is pushed downward, which in turn causes the limiting block 43 to move downward. The guide groove 42 and the limiting block 43 can ensure the movement direction of the adjusting rod 44. When the limiting block 43 moves downward, it can avoid the first universal ball 36, which can then move into the limiting groove 41, allowing the nut to be released. As the rotating table 5 continues to rotate, the second universal ball 45, the adjusting rod 44, and the limiting block 43 are pushed upward by the arc-shaped inclined surface on one side of the fixed groove 48, and the first universal ball 36 is limited.

[0033] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Instruction manual attached Figure 4 Instruction manual attached Figure 5 Included with instruction manual Figure 10A detection frame 49 is installed on the transverse material guide channel 1. The detection frame 49 is only installed above the inlet and outlet 3 at the front of the transverse material guide channel 1. The detection frame 49 includes a holding plate 50 located above the transverse material guide channel 1. The holding plate 50 is installed on the transverse material guide channel 1 through a connecting plate 51. A first photoelectric switch 52 is installed on one side of the lower end of the holding plate 50. A second photoelectric switch 53 is installed on one side of the first photoelectric switch 52 at the lower end of the holding plate 50. Two detection holes 54 are opened at the upper end of the transverse material guide channel 1. The two detection holes 54 are located below the first photoelectric switch 52 and the second photoelectric switch 53, respectively.

[0034] The process of the detection frame 49 detecting the position of the nut is as follows: After the nut is pushed into the material trough 10 and the push frame 11 returns to its original position, the detection ends of the first photoelectric switch 52 and the second photoelectric switch 53 can detect the nut through the detection hole 54. When neither the lower end of the first photoelectric switch 52 nor the second photoelectric switch 53 can detect the nut, it means that the nut has not been loaded into place yet. At this time, the nut is not loaded through the push frame 11. When both the lower ends of the first photoelectric switch 52 and the second photoelectric switch 53 can detect the nut, it means that the nut is moving in the transverse guide channel 1. At this time, the nut is still not loaded. When the lower end of the first photoelectric switch 52 cannot detect the nut and the lower end of the second photoelectric switch 53 detects the nut for 1-3 seconds, it means that the nut has moved into place. At this time, the nut is loaded through the loading frame 11.

[0035] A nut processing device has a vertical guide channel 12 installed at the input end of the nut processing device. The nut can be moved into the nut processing device through the vertical guide channel 12, which facilitates the processing of the nut.
