Therefore, in actual use, extra time is required to weigh and sort the hardware accessories. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic feeding device for hardware accessories, which can quantitatively feed hardware accessories according to a timer or according to the real-time weight of the hardware accessories inside the temporary storage box.

[0005] To achieve the above objectives, an automatic unloading device for hardware accessories is provided, comprising: a workbench, a square groove is provided on the upper left side of the workbench, a flip plate is provided on the upper end of the square groove, a connecting block two is fixedly connected to the right side of the lower center position of the flip plate, a rotating rod three is rotatably connected to the inner side of the connecting block two, a rotating rod one is rotatably connected to the left end of the inner side of the square groove, a fixing block one is fixedly connected to the outer side of the rotating rod one, a hydraulic cylinder is fixedly connected to the front end of the fixing block one, and a piston rod is slidably connected to the front end of the hydraulic cylinder;

[0006] The piston rod is fixedly connected to a second fixing block at its front end, and a first rotating rod is rotatably connected to the inner side of the second fixing block.

[0007] According to the automatic feeding device for hardware accessories, an upper connecting rod is rotatably connected to the outer sides of both ends of the rotating rod, and a lower connecting rod is rotatably connected to both ends of the rotating rod.

[0008] According to the aforementioned automatic feeding device for hardware accessories, a second rotating round rod is rotatably connected to the inner side of the lower connecting rod, and the second rotating round rod passes through the lower connecting rod and is rotatably connected to the square groove.

[0009] According to the automatic feeding device for hardware accessories, a second rotating rod is rotatably connected to the inner side of the upper connecting rod, and a first connecting block is rotatably connected to the outer side of the second rotating rod. The upper end of the first connecting block is fixedly connected to the flip plate.

[0010] According to the automatic feeding device for hardware accessories, a U-shaped frame is fixedly connected to the upper left side of the workbench, and a feeding pipe is fixedly connected to the upper center of the U-shaped frame.

[0011] According to the automatic feeding device for hardware accessories, a groove is provided on the left side of the worktable, and a discharge port is fixedly connected to the upper right side of the worktable.

[0012] According to the automatic unloading device for hardware accessories, the lower end of the workbench is fixedly connected to a support leg, and the upper end of the flip plate is fixedly connected to a temporary storage box.

[0013] According to the aforementioned automatic unloading device for hardware accessories, a rotating shaft is rotatably connected to the upper right side of the temporary storage box, and a flipping baffle is fixedly connected to the outside of the rotating shaft.

[0014] The above solution has the following beneficial effects: Activating the hydraulic cylinder pushes the piston rod at its front end forward. A fixed block two is connected to the front end of the piston rod. A rotating rod one is located on the outer side of the fixed block two. The outer side of the rotating rod one is connected to the upper connecting rod and the lower connecting rod. A rotating round rod two is located on the inner side of the front end of the lower connecting rod, and the rotating round rod two is connected to the inner side of the square groove. A rotating rod two is located on the inner side of the front end of the upper connecting rod. A connecting block one is connected to the outer side of the rotating rod two. The connecting block one is connected to the upper flip plate. A connecting block two is connected to the lower end of the flip plate. A rotating round rod three passes through the inner side of the connecting block two. When the piston rod pushes the fixed block two forward, the rotating rod one on the outer side of the fixed block two rotates synchronously. At this time, the lower connecting rod and the upper connecting rod on the outer side of the rotating rod one rotate synchronously, and the front end of the lower connecting rod is fixed by the rotating round rod two. Inside the square groove, the lower connecting rod rotates around the second rotating rod, and the upper connecting rod rotates upward, thus pushing the first connecting block to rotate. The rotation of the first connecting block causes the upper flip plate to rotate synchronously. The lower right side of the flip plate is connected to the second connecting block. The third rotating rod inside the second connecting block causes the front end of the flip plate to rotate along the third rotating rod when the flip plate rotates, thus causing the temporary storage box at the top of the flip plate to flip. When the angle of the temporary storage box changes, under the action of gravity, the flip baffle on the right side of the temporary storage box will rotate along the upper end of the rotating shaft, thus opening the flip baffle on the right side of the temporary storage box. The hardware accessories inside the temporary storage box can fall along the inside of the discharge port. By controlling the speed of the reciprocating motion of the cylinder, automatic feeding with timed and quantitative feeding is achieved.

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figure 1-4 This utility model embodiment provides an automatic feeding device for hardware accessories, which includes: a workbench 3, a square groove 21 on the upper left side of the workbench 3, a flip plate 8 on the upper end of the square groove 21, a connecting block 2 17 fixedly connected to the right side of the lower center position of the flip plate 8, a rotating round rod 3 23 rotatably connected to the inner side of the connecting block 2 17, a rotating round rod 1 11 rotatably connected to the left end of the inner side of the square groove 21, a fixing block 1 14 fixedly connected to the outer side of the rotating round rod 1 11, a hydraulic cylinder 20 fixedly connected to the front end of the fixing block 1 14, and a piston rod 18 slidably connected to the front end of the hydraulic cylinder 20.

[0025] The piston rod 18 is fixedly connected to a fixing block 15 at its front end, and a rotating rod 19 is rotatably connected to the inner side of the fixing block 15.

[0026] The outer sides of both ends of the rotating rod 19 are rotatably connected to the upper connecting rod 12, and the two ends of the rotating rod 19 are rotatably connected to the lower connecting rod 16. When the lower connecting rod 16 rotates, the front end of it will change angle with the rotating rod 19.

[0027] A rotating round rod 22 is rotatably connected to the inner side of the lower connecting rod 16. The rotating round rod 22 passes through the lower connecting rod 16 and is rotatably connected to the square groove 21. The front end of the lower connecting rod 16 is always limited by the rotating round rod 22, so that the rear end of the lower connecting rod 16 changes a large angle when it rotates, and the front end rotates along the rotating round rod 22.

[0028] The upper connecting rod 12 is rotatably connected to the inner side of the rotating rod 24, and the rotating rod 24 is rotatably connected to the outer side of the rotating rod 24. The upper end of the connecting block 13 is fixedly connected to the flip plate 8. When the upper connecting rod 12 rotates, it will drive the rotating rod 24 and the connecting block 13 at the front end to rotate synchronously, thereby causing the upper flip plate 8 to flip.

[0029] A U-shaped frame 2 is fixedly connected to the upper left side of the workbench 3. A feed pipe 1 is fixedly connected to the upper center of the U-shaped frame 2. The produced hardware parts will fall down along the feed pipe 1 into the inner side of the temporary storage box 4.

[0030] The workbench 3 has a groove 5 on the left side and a discharge port 6 is fixedly connected to the upper right side of the workbench 3. The height of the groove 5 is the same as the height of the flip plate 8, which can ensure that the flip plate 8 and the workbench 3 are at the same level during use.

[0031] The workbench 3 is fixedly connected to the lower end of the support leg 7, and the flip plate 8 is fixedly connected to the upper end of the temporary storage box 4. The temporary storage box 4 is equipped with an electronic weighing device inside, and the threshold of the electronic weighing device can be set. When the weight inside the temporary storage box 4 exceeds the threshold, the lower hydraulic cylinder 20 will be activated to push the upper flip plate 8.

[0032] A rotating shaft 9 is rotatably connected to the upper right side of the temporary storage box 4. A flip baffle 10 is fixedly connected to the outside of the rotating shaft 9. When the temporary storage box 4 is in a horizontal position, the flip baffle 10 is in a closed state. When the angle of the temporary storage box 4 changes, the flip baffle 10 will rotate along the outside of the rotating shaft 9 under the action of gravity, thus being in an open or closed state.

[0033] Working principle: During use, the manufactured hardware parts fall along the feed pipe 1 into the inner side of the temporary storage box 4. The temporary storage box 4 is equipped with an electronic weighing device, which can weigh and quantify the hardware parts inside the temporary storage box 4 in real time. When the hardware parts inside the temporary storage box 4 exceed the threshold, it will send a signal to the hydraulic cylinder 20, causing the hydraulic rod 20 to start and push the piston rod 18 at the front end. The piston rod 18 has a fixing block 15 at the front end. When the piston 18 pushes the fixing block 15 forward, the rotating rod 19 outside the fixing block 15 rotates synchronously. At this time, the lower connecting rod 16 and the upper connecting rod 12 outside the rotating rod 19 rotate synchronously. The front end of the lower connecting rod 16 is fixed inside the square groove 21 by the rotating round rod 22. Therefore, the lower connecting rod 16 rotates around the rotating round rod 22, and the upper connecting rod 16 rotates upward. The connecting block 13 is rotated, causing the upper flip plate 8 to rotate synchronously. The lower right side of the flip plate 8 is connected to the connecting block 2 17. The rotating rod 3 23 inside the connecting block 2 17 can rotate the front end of the flip plate 8 along the rotating rod 3 23 when the flip plate 8 rotates, thereby causing the temporary storage box 4 at the upper end of the flip plate 8 to flip. When the angle of the temporary storage box 4 changes, the flip baffle 10 on the right side of the temporary storage box 4 will rotate along the upper end of the rotating shaft 9 under the action of gravity, thereby opening the flip baffle 10 on the right side of the temporary storage box 4. The hardware accessories inside the temporary storage box 4 can fall along the inside of the discharge port 6. By controlling the threshold of the electronic weighing device inside the temporary storage box 4 or the pushing speed of the hydraulic cylinder 20, the automatic feeding function of hardware accessories at time and quantity can be realized.

[0034] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
