DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] The core of the present invention is to provide a nut automatic conveying and anti-accumulation and material-removing mechanism, which can effectively improve the automatic conveying effect of the nuts.

[0032] Please refer to Figures 1 to 4 ,in, Figure 1 This is a structural diagram of the nut automatic conveying and anti-accumulation and material removal mechanism provided by the present invention; Figure 2 This is a partial schematic diagram of the nut automatic conveying and anti-accumulation and material removal mechanism from another perspective; Figure 3 Schematic diagram of the structure of the adjustment plate; Figure 4 Schematic diagram of the structure of the guide bar.

[0033] This specific embodiment provides a nut automatic conveying and anti-accumulation and material removal mechanism, comprising:

[0034] A silo for accommodating nuts 2;

[0035] A conveyor belt 3 is provided above the silo and is used to convey the nuts 2;

[0036] The lifting device 4 is located above the silo and can move up and down to lift the nuts 2 from the silo to the conveyor belt 3.

[0037] a guide plate 5, which is vertically arranged on a side of the conveyor belt 3 away from the lifting device 4;

[0038] An adjustment plate 6 is connected to the guide plate 5 and is provided with a rejecting member 61 for rejecting nuts 2 that do not conform to the installation posture and an adjusting member 62 for adjusting the size of the channel entrance 7 according to the size of the nut 2. The adjusting member 62 and the channel entrance 7 are both located at the end of the adjustment plate 6;

[0039] The blanking port 8 is arranged opposite to the regulating plate 6 , and the top end of the blanking port 8 is connected to the conveyor belt 3 , and the bottom end of the blanking port 8 is connected to the silo.

[0040] It should be noted that the guide plate 5 is located above the lifting device 4 and is arranged perpendicular to the conveyor belt 3. When the nuts 2 pass through the lifting device 4 and fall onto the conveyor belt 3, the guide plate 5 prevents the nuts 2 from falling off the other side of the conveyor belt 3. The guide plate 5 also prevents the nuts 2 from stacking and guides the orderly flow of the nuts 2. The drop port 8 is used to return the fallen nuts 2 to the hopper at the lower end after the removal member 61 has removed them.

[0041] During actual use, the shape, structure, size, material, etc. of the silo, conveyor belt 3, lifting device 4, guide plate 5, adjustment plate 6 and drop port 8 can be determined according to actual conditions and actual needs.

[0042] When using the automatic nut conveying and anti-stacking mechanism provided by the present invention, the lifting device 4 can first be controlled to operate to lift the nuts 2 in the hopper onto the conveyor belt 3. When the lifting device 4 reaches its highest point, the nuts 2 will fall onto the conveyor belt 3, where the nuts 2 are now stacked in various shapes. The nuts 2 can then be transported forward along the conveyor belt 3 along the guide plate 5. The guide plate 5 can knock multiple stacked nuts 2 into the lifting device 4 for re-lifting, while the remaining nuts 2 can continue to be transported forward. When the nuts 2 are transported to the removal member 61, the removal member 61 can effectively remove nuts 2 that do not conform to the installation posture. Nuts 2 that do not conform to the installation posture will fall back into the hopper through the drop-out port 8 and then be re-lifted by the lifting device 4. At the same time, the size of the channel entrance 7 can be adjusted by the adjustment member 62 to ensure that only a single nut 2 that conforms to the installation posture passes through the channel entrance 7 in sequence. Finally, nuts 2 that conform to the installation posture and enter the subsequent channel through the channel entrance 7 can continue to be transported forward under the action of the conveyor belt 3 until they enter the next process for automated assembly and removal.

[0043] In summary, the nut automatic conveying and anti-accumulation and material removal mechanism provided by the present invention can effectively improve the automatic conveying effect of the nuts 2.

[0044] On the basis of the above embodiment, preferably, the lifting device 4 includes a lifting part for loading the nut 2 and a lifting part for driving the lifting part to move up and down. The lifting part is a staggered step structure composed of multiple lifting plates, and the structure is shown in the figure.

[0045] It should be noted that the lifting device 4 is driven by the power of the lifting part, so that the lifting part periodically lifts from low to high, lifts the nuts 2 from the silo to the highest point, and drops them from the highest point onto the conveyor belt 3. The lifting part is set as a staggered step structure composed of multiple lifting plates, which ensures that the lifting part can pick up multiple nuts 2 at a time and drive multiple nuts 2 to rise and fall synchronously.

[0046] Preferably, the lifting part is a lifting cylinder or a screw nut 2 driving member to ensure that the lifting part performs a stable and accurate lifting operation. Of course, the lifting part can also be set to other structures that can perform a lifting operation.

[0047] Preferably, the ejector 61 includes an ejector rod 611 for limiting the outer diameter of the nut 2 to allow a single nut 2 to be conveyed on the conveyor belt 3, and an ejector plate 612 for limiting the height of the nut 2 to screen the posture of the nut 2. The ejector rod 611 can push excess nuts 2 arranged side by side into the ejection port 8 to ensure that the nuts 2 move one by one on the conveyor belt 3. The ejector plate 612 can push stacked nuts 2 into the ejection port 8 to ensure that only nuts 2 that meet the installation posture enter the subsequent channel for removal and assembly.

[0048] Preferably, the pick rod 611 is a U-shaped double-ended folded rod that is horizontally arranged through the adjustment plate 6. The side of the U-shaped double-ended folded rod has an inclined angle, and the distance between the narrowest part of the pick rod 611 and the other side of the conveyor belt 3 is equal to the outer diameter of the nut 2. Therefore, when nuts 2 that do not conform to the installation posture or nuts 2 that are arranged side by side move to the pick rod 611, the pick rod 611 can arrange the crowded nuts 2 in an orderly manner and push the nuts 2 that do not conform to the installation posture to the drop port 8, and then fall back into the hopper and be lifted again.

[0049] Preferably, the pick-up plate 612 is a flat plate structure horizontally arranged on the adjustment plate 6, and half of the difference between the outer contour diameter of the nut 2 and the outer diameter of the nut 2 is a preset difference. The height of the pick-up plate 612 is greater than the height of the nut 2, and the height of the pick-up plate 612 is less than the sum of the outer diameter of the nut 2 and the preset difference.

[0050] It should be noted that the pick rod 611 may not be able to accurately screen the incoming nuts 2. In other words, the nuts 2 that have passed the pick rod 611 may not conform to the installation posture. In this case, the pick plate 612 can once again screen the incoming nuts 2. In addition, the height of the pick plate 612 is greater than the height of the nut 2, and the height of the pick plate 612 is less than the sum of the outer diameter of the nut 2 and the preset difference. Setting the height of the pick plate 612 in the above range ensures that stacked or overturned nuts 2 cannot pass through the pick plate 612.

[0051] Preferably, the end of the adjustment plate 6 includes an inclined plate 63 and an L-shaped plate 64 connected in sequence, the distance between the end of the inclined plate 63 and the other side of the conveyor belt 3 is smaller than the distance between the head end of the inclined plate 63 and the other side of the conveyor belt 3, and the vertical portion of the L-shaped plate 64 is connected to the end of the inclined plate 63; the horizontal portion of the L-shaped plate 64 is provided with an adjustment hole in the horizontal direction, and the adjustment member 62 includes a mounting plate 622 movable relative to the adjustment hole and an adjustment bolt 621 provided on the mounting plate 622, and the structure is as follows: Figure 2-4The ejection plate 612 can be arranged between the inclined plate 63 and the middle portion of the regulating plate 6 so that the distance between the ejection plate 612 and the other side of the conveyor belt 3 is gradually reduced to further screen the nuts 2.

[0052] When it is necessary to adjust the size of the channel entrance 7 according to the specific size of nuts 2 of different models and sizes, the mounting plate 622 can be moved laterally along the adjustment hole to change the installation position of the mounting plate 622, thereby adjusting the position of the adjusting bolt 621 on the mounting plate 622, and changing the distance between the adjusting bolt 621 and the other side of the conveyor belt 3, so as to effectively change the size of the channel entrance 7 and ensure that a single nut 2 that meets the installation posture can pass smoothly through the channel entrance 7.

[0053] Preferably, a guide bar 1 is provided at the channel entrance 7, and the guide bar 1 is arranged opposite to the adjustment plate 6. The end of the guide bar 1 widens from narrow to wide along the conveying direction, so as to cooperate with the adjustment bolt 621 and the L-shaped plate 64 to push the nut 2 to the side close to the guide bar 1. Figure 4 As shown, the nut 2 that is tilted to one side is not in the correct installation position, while the nut 2 that is only vertically flat is the correct installation position. Therefore, the guide bar 1 can cooperate with the adjustment bolt 621 and the L-shaped plate 64 to push the nut 2 that is in the correct installation position to the side close to the guide bar 1, so that the position of the nut 2 entering the subsequent conveyor belt 3 remains consistent, meeting the requirements of automated assembly and retrieval.

[0054] In order to further illustrate the use of the nut automatic conveying and anti-accumulation and material removal mechanism provided by the present invention, an example is given below.

[0055] Step 1: The nuts 2 in the silo are lifted multiple times by the lifting plate to reach the highest point, so that the nuts 2 can fall onto the conveyor belt 3. At this time, the nuts 2 are piled up in various shapes;

[0056] Step 2: The nuts 2 are transported forward along the guide plate 5 via the conveyor belt 3. The guide plate 5 knocks down multiple stacked nuts 2 onto the lifting plate and lifts them up again. The remaining nuts 2 continue to be transported forward.

[0057] Step 3: When the nut 2 is transported to the pick rod 611, the pick rod 611 makes the transport width of the nut 2 narrower, and the distance between the narrowest part of the pick rod 611 and the other side of the conveyor belt 3 is the outer diameter of the nut 2, which can squeeze out the crowded nuts 2 and ensure that the individual nuts 2 are transported in sequence. At the same time, the narrowest part of the pick rod 611 can be adjusted to meet the needs of nuts 2 of different sizes.

[0058] Step 4: When the nuts 2 arrive at the ejection plate 612 in a single order, the ejection plate 612 mainly removes the nuts 2 that do not conform to the installation posture by limiting the height. Most of the nuts 2 after passing the ejection plate 612 are nuts 2 that conform to the installation posture. The nuts 2 are conveyed to the channel entrance 7 of the nut channel that conforms to the installation posture. By pre-adjusting the installation plate 622 and adjusting the bolt 621, the distance from the channel entrance 7 is slightly smaller than the outer contour diameter of the nut 2.

[0059] Step 5: When the nut 2 passes through the channel entrance 7, the outermost portion of the nut 2 slightly protrudes from the channel. When the nut 2 passes through the guide bar 1, the nut 2 that meets the installation posture can be pushed to one side of the guide bar 1, so that the position of the nut 2 entering the nut channel that meets the installation posture remains consistent. At the same time, the guide bar 1 can also remove the remaining few nuts 2 that do not meet the installation posture after passing through the reject plate 612.

[0060] Step 6: The nut 2 that has entered the nut channel in the correct installation posture can continue to be transported forward along the conveyor belt 3 and wait to enter the next process for automated assembly and use.

[0061] In addition, it should be noted that the orientations or positional relationships indicated by "horizontal", "vertical", "up and down", etc. in this application are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the purpose of simplifying the description and facilitating understanding, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
