[0002] A hinge is a mechanical device used to connect two solid objects and allow relative rotation between them. Hinges can be made of movable components or foldable materials. During the manufacturing process, the protruding ends of the hinge need to be chamfered, drilled, and other processing operations, and the hinges need to be fed into the machine.

[0003] Patent No. CN219362234U discloses an automatic feeding device for hinge plate assembly, including a fixed plate, a worktable, and a partition plate.

A second support column is fixedly connected to one side of the bottom of the worktable and is symmetrically distributed. The second support column is located on the bottom side of the worktable away from the fixed plate. The partition plate is located at the top of the conveyor belt and in the center. Support rods are fixedly connected to both ends of the partition plate away from the worktable. The conveyor belt facilitates the transfer of objects from one end to the other. The partition plate is made of rubber and effectively divides the top of the conveyor belt into two areas. The partition plate works in conjunction with the conveyor belt for feeding and unloading, improving the efficiency of hinge plate assembly and reducing labor costs.

[0004] In existing technologies, partitions are used to divide the top of the conveyor belt into two areas. The partitions work with the conveyor belt for loading and unloading, reducing manpower consumption. However, the following problems exist in the overall use: First, when processing large cylindrical hinges, existing technologies cannot correct the hinge's deviation during loading. Other devices or workers are required to straighten or adjust the direction, resulting in low processing efficiency. Second, existing devices use free fall for loading, which can easily cause jamming, affecting work efficiency. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this utility model provides an automatic feeding device for hinge processing. By setting two staggered sliding movable plates, the hinge can be blocked and fed when the movable plates slide, thereby preventing jamming. By setting a correction plate, a U-shaped groove, and adjusting push blocks and push-out blocks, the hinge can be corrected, so that the hinge is pushed out in a uniform direction, thereby improving processing efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic feeding device for hinge processing, comprising a bracket, a limiting cylinder at the bottom of the bracket, a correction plate inside the limiting cylinder, a U-shaped groove on the end face of the correction plate, an adjustment port on one side of the correction plate at the bottom of the inner wall of the limiting cylinder, two adjusting push blocks slidably disposed on one side of the adjustment port, a push block disposed between the two adjusting push blocks, a discharge port symmetrically disposed on one side of the adjustment port at the bottom of the inner wall of the limiting cylinder, a discharge baffle on one side of the discharge port, two auxiliary plates rotatably disposed on the top of the discharge baffle, two movable plates slidably disposed inside the limiting cylinder, a feeding chamber slidably disposed on the top of the two movable plates, a push rod rotatably disposed on one side of the feeding chamber, and the push rod abutting against the outer surface of the feeding chamber.

A connecting rod is rotatably provided on the end face of each of the two turntables, and a rotating connecting member is rotatably provided at one end of each of the two connecting rods. The two rotating connecting members are respectively fixedly connected to two movable plates. Two sliding grooves are provided inside the limiting cylinder, and the two sliding grooves are slidably connected to the movable plates.

[0008] Preferably, one side of the limiting cylinder is provided with a sliding plate that is slidably provided inside the cylinder, and the outer surface of the sliding plate is provided with a plurality of mounting blocks, which are respectively connected to the adjusting push block and the pushing block.

[0009] Preferably, a limiting slide rail is provided at the top of the inner wall, and a limiting slide groove is provided at the top of the sliding plate. The limiting slide groove is slidably connected to the limiting slide rail. A cylinder is provided on one side of the sliding plate and outside the feeding chamber, and the output end of the cylinder is fixedly connected to the sliding plate.

[0010] Preferably, the transmission rod is fixedly connected to the bottom end face of the push rod, and a drive motor is provided at the bottom of the transmission rod, with the output end of the drive motor fixedly connected to the transmission rod.

[0011] Preferably, the support has multiple elastic support plates on its end face, and one end of each of the multiple elastic support plates is provided with a fixing frame, which is fixedly connected to the unloading chamber.

[0012] Preferably, the top of the discharge baffle is symmetrically provided with two mounting seats, each mounting seat has a rotating shaft on its end face, and each rotating shaft is externally connected with a torsion spring, which is also fixedly connected to the auxiliary plate.

[0013] Preferably, the sliding plate has multiple adjustment holes on its end face, and the mounting block is connected to the adjustment holes by bolts.

[0014] In summary, compared with existing technologies, the beneficial effects of this solution are as follows:

[0015] (1) This utility model, by setting a correction plate and a U-shaped groove, as well as an adjusting push block and an ejection block, makes the hinge abut against the end face of the correction plate, and makes the adjusting push block sliding on one side push one end of the hinge, so that the hinge flips, thereby correcting the orientation of the hinge when it is ejected, so that the hinge is ejected in a uniform direction, thereby effectively improving the processing efficiency.

Detailed Implementation

[0027] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Example 1:

[0029] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 An automatic feeding device for hinge processing includes a bracket 10, a limiting cylinder 11 at the bottom of the bracket 10, a correction plate 19 inside the limiting cylinder 11, a U-shaped groove 20 on the end face of the correction plate 19, an adjustment port 13 on one side of the correction plate 19 at the bottom of the inner wall of the limiting cylinder 11, two adjustment push blocks 14 slidably arranged on one side of the adjustment port 13, a push block 15 between the two adjustment push blocks 14, a discharge port 21 symmetrically arranged on one side of the adjustment port 13 at the bottom of the inner wall of the limiting cylinder 11, a discharge baffle 22 on one side of the discharge port 21, two auxiliary plates 23 rotatably arranged on the top of the discharge baffle 22, two movable plates 12 slidably arranged inside the limiting cylinder 11, a feeding chamber 35 slidably arranged on the top of the two movable plates 12, a push rod 32 rotatably arranged on one side of the feeding chamber 35, and the push rod 32 abutting against the outer surface of the feeding chamber 35.

[0030] In this design, the limiting cylinder 11 has a hollow interior, which can only slide downwards longitudinally through a hinge. This allows the hinge to abut against the end face of the correction plate 19, thus restricting the sliding direction of the hinge and correcting its deviation. The correction plate 19 is U-shaped, and the U-shaped groove 20 on its end face allows the protrusion of the hinge to pass through. This allows one of the adjusting push blocks 14 to contact one end of the hinge protrusion during sliding and push it, causing the hinge to rotate. This ensures that the end of the hinge with the protrusion always points towards the discharge port 21, thereby correcting the hinge's direction, facilitating uniform processing, and improving processing efficiency. The unloading chamber 35 is funnel-shaped, and its interior is used to load the hinges to be processed.

[0031] refer to Figure 4 , Figure 5 and Figure 6 A transmission rod 27 is rotatably mounted on one side of the limiting cylinder 11. Two turntables 28 are mounted on the outer surface of the transmission rod 27. A connecting rod 29 is rotatably mounted on the end face of each of the two turntables 28. A rotating connecting piece 30 is rotatably mounted on one end of each of the two connecting rods 29. The two rotating connecting pieces 30 are fixedly connected to the two movable plates 12 respectively. Two sliding grooves 31 are opened inside the limiting cylinder 11. The two sliding grooves 31 are slidably connected to the movable plates 12. The bottom end face of the transmission rod 27 is fixedly connected to the bottom face of the push rod 32. A drive motor 39 is mounted on the bottom of the transmission rod 27. The output end of the drive motor 39 is fixedly connected to the transmission rod 27.

[0032] In this design, the two connecting rods 29 and the rotating connector 30 on the end faces of the two transmission rods 27 are symmetrically arranged. The transmission rods 27 can only reciprocate 180 degrees, thereby causing the two adjustment ports 13 to reciprocate in an alternating manner. This arrangement can separate the two abutting hinges inside the limiting cylinder 11, allowing only one hinge to slide down at a time, thus preventing the hinges from getting stuck inside the limiting cylinder 11 and improving the overall stability of the device. One end of the movable plate 12 is knife-shaped, which makes it easier to separate the two hinges. When the transmission rods 27 rotate, they will drive the push rod 32 at the top to rotate. The push rod 32 is cross-shaped, and its four protruding ends will push the side wall of the feeding chamber 35 when rotating, causing the feeding chamber 35 to swing. This causes the feeding chamber 35 to drive the internal hinges to swing. This arrangement can prevent the hinges from getting stuck at the outlet of the feeding chamber 35, thereby improving the stability of the device's feeding.

[0033] refer to Figure 2 , Figure 3 The limiting cylinder 11 has an installation chamber 40 on one side. The installation chamber 40 has a sliding plate 17 inside. The outer surface of the sliding plate 17 has multiple installation blocks 16, which are respectively connected to the adjusting push block 14 and the pushing block 15.

[0034] In this scheme, the hinge slides inside the limiting cylinder 11. When the protruding end of the hinge faces the bottom, the protruding end of the hinge will be inserted into the U-shaped groove 20. The correction plate 19 abuts against the thicker end face of the hinge. When the two adjusting push blocks 14 move toward the hinge, the bottom adjusting push block 14 will contact the protruding end, while the top adjusting push block 14 will slide at the top of the hinge because the protruding end of the hinge is inserted downwards, resulting in the overall height of the hinge being insufficient to contact the top adjusting push block 14. When the bottom adjusting push block 14 pushes the protruding end of the hinge to move, it will cause the protruding end to rotate toward the discharge port 21 and be pushed out by the push block 15.

[0035] When the protruding end of the hinge faces the top, it cannot be inserted into the U-shaped groove 20. As a result, when the top adjusting push block 14 moves, it will first contact the protruding end of the hinge, thereby pushing the hinge to tilt. This causes the protruding end of the hinge to tilt towards the discharge port 21. Thus, the hinge in both states can be corrected in direction through the U-shaped groove 20 and the adjusting push block 14, and pushed out in a unified direction, thereby improving the feeding efficiency.

[0036] refer to Figure 2 , Figure 3 , Figure 8 and Figure 9 The top of the inner wall of the installation chamber 40 is provided with a limiting slide rail 36, and the top of the sliding plate 17 is provided with a limiting slide groove 37. The limiting slide groove 37 is slidably connected to the limiting slide rail 36. A cylinder 38 is provided on one side of the sliding plate 17 and the outside of the unloading chamber 35. The output end of the cylinder 38 is fixedly connected to the sliding plate 17. Multiple adjustment holes 18 are provided on the end face of the sliding plate 17. The mounting block 16 is connected to the adjustment holes 18 by bolts.

[0037] In this design, multiple mounting blocks 16 can be fixed to the adjusting holes 18 by bolts, thereby adjusting the position of the mounting blocks 16. This allows the adjusting push block 14 and the pushing block 15 on one side of the mounting block 16 to be adjusted according to the hinge specifications, thus enabling the device to adapt to large hinges of various specifications and improving the overall flexibility of the device.

[0038] refer to Figure 1 , Figure 2 and Figure 3 Multiple elastic support plates 33 are provided on the end face of the bracket 10, and a fixing frame 34 is provided on one end of the multiple elastic support plates 33. The fixing frame 34 is fixedly connected to the unloading chamber 35.

[0039] In this design, the elastic support plate 33 is made of metal and can provide support for the fixed frame 34, thereby improving the stability of the fixed frame 34.

[0040] refer to Figure 1 and Figure 7 The top of the discharge baffle 22 is symmetrically provided with two mounting seats 24. Each mounting seat 24 has a rotating shaft 25 on its end face. Each rotating shaft 25 has a torsion spring 26 on its outside. The torsion spring 26 is fixedly connected to the auxiliary plate 23.

[0041] In this design, by setting an auxiliary plate 23, one side of the hinge can be blocked, so that when the adjusting push block 14 pushes the protruding end of the hinge, the auxiliary plate 23 can block the surface of the hinge, thereby causing the hinge to flip under the push of the adjusting push block 14, and through the subsequent push of the push block 15, the hinge pushes open the two auxiliary plates 23 and slides out from the inside of the discharge port 21, thereby improving the stability of the device.

[0042] In use, the processing hinge is placed inside the feed chamber 35, and then the drive motor 39 is started. The output shaft of the drive motor 39 drives the transmission rod 27 to rotate. The transmission rod 27 drives the push rod 32 at the top to rotate back and forth. During the back and forth rotation, the push rod 32 continuously pushes the feed chamber 35 on one side, causing the feed chamber 35 to swing on the surface of the limiting cylinder 11, so that the hinge inside the feed chamber 35 falls into the inside of the limiting cylinder 11 and abuts against the top end face of the movable plate 12.

[0043] During rotation, the transmission rod 27 drives two turntables 28, which in turn drive two connecting rods 29 to rotate. One connecting rod 29, when rotating, drives a rotating connector 30 at one end, which in turn pulls a movable plate 12 at one end, causing the hinge of the top movable plate 12 to fall onto the end face of the bottom movable plate 12. When the transmission rod 27 rotates, the bottom turntable 28 pushes another connecting rod 29, which in turn pushes the rotating connector 30, causing the rotating connector 30 to push the bottom movable plate 12, thus blocking the hinge. When the transmission rod 27 rotates in the opposite direction, the bottom movable plate 12 moves in the opposite direction, causing the hinge on the end face of the bottom movable plate 12 to fall onto the end face of the correction plate 19, while the top movable plate 12 pushes into the limiting cylinder 11, thereby blocking the hinge to be processed and preventing it from affecting the correction work of the bottom hinge.

[0044] When the protruding end of the hinge faces the bottom, the protruding end of the hinge will be inserted into the U-shaped groove 20. The correction plate 19 will abut against the thicker end face of the hinge. When the two adjusting push blocks 14 move toward the hinge, the bottom adjusting push block 14 will contact the protruding end, while the top adjusting push block 14 will slide at the top of the hinge because the protruding end of the hinge is inserted downwards, and the overall height of the hinge is not enough to contact the top adjusting push block 14. When the bottom adjusting push block 14 pushes the protruding end of the hinge to move, it will cause the protruding end to rotate toward the discharge port 21 and be pushed out by the push block 15 to complete the feeding.

[0045] When the protruding end of the hinge faces the top, the protruding end of the hinge cannot be inserted into the U-shaped groove 20. As a result, when the top adjusting push block 14 moves, it will first contact the protruding end of the hinge, thereby pushing the hinge to tilt. This causes the protruding end of the hinge to tilt towards the discharge port 21, so that the hinge in both states can be corrected in direction through the U-shaped groove 20 and the adjusting push block 14, and pushed out in a unified direction.
