Two sets of the third cylinders are arranged opposite each other. The two sets of third cylinders are used to push the two sets of hinge bodies side-by-side closer to each other. The discharge port of the bolt feeding device extends between the hinge conveying device and the third cylinder.
[0011] Preferably, a fifth cylinder is arranged horizontally above the second guide plate, and a fourth cylinder is installed on the telescopic rod of the fifth cylinder.

[0028] 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. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0029] Example 1
[0030] Reference Figure 1 , Figure 2 A hinged box-packing device, including a bagging device X5, and further comprising:
[0031] The feeding and unloading mechanism includes a hinge feeding device X1 and a hinge conveying device X3 arranged in sequence. The output side of the hinge conveying device X3 is connected to the input side of the bagging device X5. A hinge transfer device X2 is also provided between the hinge feeding device X1 and the hinge conveying device X3. A bolt feeding device X4 is also provided on one side of the hinge conveying device X3.
[0032] The material discharge and boxing mechanism includes a finished product discharge device X6 and a finished product boxing device X7 arranged in sequence. The input side of the finished product discharge device X6 is connected to the output side of the bagging device X5. A finished product transfer device X8 is also provided between the finished product discharge device X6 and the finished product boxing device X7.
[0033] Workflow:
[0034] The hinge body 28 is continuously fed to the hinge feeding device X1. The hinge transfer device X2 transfers the hinge body 28 from the hinge feeding device X1 to the hinge conveying device X3. During the conveying of the hinge body 28, the bolt feeding device X4 uses a feeding vibrating plate to feed the bolts used for installing the hinge body 28 to one side of the hinge body 28. The hinge conveying device X3 then transports the hinge body 28 and the bolts on one side of the hinge body 28 to the bagging device X5. The bagging device X5 is a pillow-type packaging machine. The X5 device performs bagging and packaging operations on the hinge body 28 and bolts. After bagging and packaging, the hinge body 28 and bolts are output from the bagging device X5 to the finished product discharge device X6. At the same time, the finished product boxing device X7 supplies packaging boxes 29. The finished product transfer device X8 transfers the bagged and packaged hinge body 28 and bolts from the finished product discharge device X6 to the packaging box 29. When the packaging box 29 is loaded with the set number of products, it is output out through the finished product transfer device X8, thus completing the packaging and boxing operation of the hinge body 28.
[0035] Example 2
[0036] To better convey the hinge body 28 to the bagging device X5, refer to Figure 3 The hinge feeding device X1 includes a first conveyor belt 1. The input end of the first conveyor belt 1 is provided with a first guide plate 2. Two sets of first guide plates 2 are arranged opposite each other. The side of the two sets of first guide plates 2 near the input end of the first conveyor belt 1 has a trumpet-shaped structure. The upper end of the hinge body 28 can be guided between the two sets of first guide plates 2. The output end of the first conveyor belt 1 is provided with a first baffle 5. The outer end face of the first baffle 5 is fixedly installed with a second sensor 6 by bolts. The second sensor 6 is used to sense whether the hinge body 28 is in close contact with the first baffle 5. A first cylinder 3 is also installed in the middle of the first conveyor belt 1. The telescopic rod of the first cylinder 3 can be inserted into the cup bowl of the hinge body 28 and prevent the hinge body 28 from moving. A first sensor 4 is also installed on one side of the first cylinder 3. The first sensor 4 is used to sense whether the hinge body 28 is present at the lower end of the first cylinder 3.
[0037] Furthermore, refer to Figure 4 The hinge transfer device X2 includes a mounting frame 7, on which two sets of first rotating rods 8 are rotatably mounted. The same end of the two sets of first rotating rods 8 rotates synchronously through a synchronous pulley and a synchronous belt. A second rotating rod 9 is rotatably connected between the outer ends of the two sets of first rotating rods 8. A second cylinder 10 is horizontally mounted at the lower end of the second rotating rod 9. The telescopic rod of the second cylinder 10 is connected to a reversing gripper 11. The two sets of hinge bodies 28 can be placed side by side and upside down through the second cylinder 10 and the reversing gripper 11.
[0038] Furthermore, refer to Figure 5The hinge conveying device X3 includes a second conveyor belt 12. Two sets of fourth sensors 30 are installed side by side at the input end of the second conveyor belt 12. The two sets of fourth sensors 30 are used to detect whether there are two sets of hinge bodies 28 side by side at the input end of the second conveyor belt 12. A second guide plate 14 is provided at the output end of the second conveyor belt 12. Two sets of second guide plates 14 are arranged opposite each other. The side of the two sets of second guide plates 14 near the input end of the second conveyor belt 12 is a trumpet-shaped structure. The upper end of the hinge body 28 can be guided between the two sets of second guide plates 14. A third cylinder 13 is also provided at the input end of the two sets of second guide plates 14. Two sets of third cylinders 13 are arranged opposite each other. The two sets of third cylinders 13 are used to push the two sets of hinge bodies 28 side by side closer to each other. The discharge port of the bolt feeding device X4 extends to the space between the hinge transfer device X2 and the third cylinder 13.
[0039] Furthermore, refer to Figure 5 A fifth cylinder 17 is horizontally arranged above the second guide plate 14. The telescopic rod of the fifth cylinder 17 is equipped with a fourth cylinder 16 arranged longitudinally. The telescopic rod of the fourth cylinder 16 is connected to two sets of second guide plates 14. A second baffle 15 is also bent between the two sets of second guide plates 14. The second baffle 15 is used to prevent the hinge body 28 from moving.
[0040] Workflow:
[0041] The process of hinge feeding device X1: Multiple hinge bodies 28 are sequentially fed to the first conveyor belt 1. The cup-shaped opening of the hinge body 28 should face upward. When the hinge body 28 is fed along the first conveyor belt 1, the upper end of the hinge body 28 will contact the first guide plate 2. Under the guidance of the first guide plate 2, the hinge body 28 will not deviate on the first conveyor belt 1.
[0042] To prevent multiple hinge bodies 28 from squeezing each other, when the first sensor 4 detects the passage of the first hinge body 28, the first cylinder 3 will not be triggered. When the second sensor 6 detects the first hinge body 28, it indicates that the first hinge body 28 has contacted the first baffle 5. At this time, the first conveyor belt 1 continues to transport the hinge bodies 28. When the first sensor 4 detects the passage of the second hinge body 28, and the second sensor 6 can still sense the first hinge body 28, the first cylinder 3 starts to work. The telescopic rod of the first cylinder 3 extends and inserts into the cup-shaped opening of the second hinge body 28, preventing the second hinge body 28 from continuing to move. After the first hinge body 28 is transferred by the hinge transfer device X2, the second sensor 6 can no longer sense the first hinge body 28. At this time, the telescopic rod of the first cylinder 3 retracts, and the second hinge body 28 is no longer restricted. The two sets of hinge bodies 28 are conveyed by the first conveyor belt 1 and come into contact with the first baffle 5. The second sensor 6 senses the second set of hinge bodies 28. At this time, the first conveyor belt 1 is still continuously conveying the hinge bodies 28. When the first sensor 4 detects the passage of the third set of hinge bodies 28 and the second sensor 6 can still sense the second set of hinge bodies 28, the first cylinder 3 starts to work. The telescopic rod of the first cylinder 3 extends and inserts into the cup mouth of the third set of hinge bodies 28. This cycle is repeated to release multiple sets of hinge bodies 28 one by one, avoiding the multiple sets of hinge bodies 28 from squeezing each other. Through the cooperation of the first guide plate 2 and the first cylinder 3, it is also possible to avoid the first cylinder 3 forcing the hinge bodies 28 to shift when it comes into contact with the hinge bodies 28. In order to further improve the neatness of the hinge bodies 28, the first cylinder 3 and the first sensor 4 can be arranged in multiple sets along the first guide plate 2.
[0043] The process of hinge transfer device X2: The reversing gripper 11 includes a reversing motor, a push cylinder, and a clamping rod. When the second sensor 6 senses the hinge body 28, refer to... Figure 4The two sets of first rotating rods 8 rotate counterclockwise synchronously, driving the second rotating rod 9 to move to the left side of the mounting frame 7. The second cylinder 10 is activated to adjust the position of the reversing gripper 11, aligning its clamping bar with the hinge body 28 on the first conveyor belt 1. The pushing cylinder of the reversing gripper 11 is activated, allowing its clamping bar to move downwards and clamp the hinge body 28 on the first conveyor belt 1. Then, the two sets of first rotating rods 8 rotate clockwise, driving the second rotating rod 9 to move to the left side of the mounting frame 7. On the right side, when reversing is not required, the push cylinder of the reversing gripper 11 is activated, so that the gripper arm of the reversing gripper 11 can move downward and place the hinge body 28 on the second conveyor belt 12. When reversing is required, the reversing motor of the reversing gripper 11 is activated, so that the push cylinder and the gripper arm of the reversing gripper 11 rotate 180°. Then, the second cylinder 10 is activated to adjust the position of the reversing gripper 11. Finally, the push cylinder of the reversing gripper 11 is activated, so that the gripper arm of the reversing gripper 11 can move downward and place the hinge body 28 on the second conveyor belt 12.
[0044] The process of the hinge conveying device X3: The reversing gripper 11 places two sets of hinge bodies 28 side by side on the second conveyor belt 12, and the two sets of hinge bodies 28 are placed upside down to save space and avoid wasting space by having the cup openings of the two sets of hinge bodies 28 on the same side. When the fourth sensor 30 simultaneously senses the two sets of hinge bodies 28, the second conveyor belt 12 continues to convey the two sets of hinge bodies 28 side by side. When passing the bolt feeding device X4, the feeding vibrating plate of the bolt feeding device X4 conveys the bolts between the two sets of hinge bodies 28. The two sets of hinge bodies 28, which have bolts and are placed side by side, continue to move under the drive of the second conveyor belt 12. When passing the third air... When cylinder 13 is engaged, the telescopic rods of the two sets of third cylinders 13 extend, causing the two sets of hinge bodies 28, which are bolted and placed side by side, to move closer to each other. The two sets of hinge bodies 28 are continuously conveyed by the second conveyor belt 12, and the two guide plates 14 prevent the two sets of hinge bodies 28 from loosening. The fourth cylinder 16 adjusts the height of the second guide plate 14 and the second baffle 15, and the fifth cylinder 17 adjusts the lateral position of the fourth cylinder 16, the second guide plate 14, and the second baffle 15. The hinge bodies 28 are pushed by the cooperation of the fifth cylinder 17 and the fourth cylinder 16, so that the hinge bodies 28 are pushed into the bagging device X5. During the pushing process, the second guide plate 14 prevents the hinge bodies 28 from loosening.
[0045] Example 3
[0046] To better facilitate the unloading and packing operations, refer to Figure 6The finished product discharge device X6 includes a first weighing device 18. The input end of the first weighing device 18 is connected to the output end of the bagging device X5. A third conveyor belt 19 is connected to the output end of the first weighing device 18. A third guide plate 20 is provided at the input end of the third conveyor belt 19. Two sets of third guide plates 20 are arranged opposite each other. The side of the two sets of third guide plates 20 closest to the first weighing device 18 has a trumpet-shaped structure. The packaged hinge body 28 can be guided between the two sets of third guide plates 20. A sixth cylinder 21 and a temporary storage plate 23 are respectively installed on the left and right sides of the output end of the third conveyor belt 19. The sixth cylinder 21 can push the packaged hinge body 28 on the third conveyor belt 19 to the temporary storage plate 23.
[0047] Furthermore, refer to Figure 6 It also includes two sets of third sensors 22, which are respectively set on the left and right sides of the sixth cylinder 21. The third sensors 22 are used to detect whether there are two sets of packaged hinge bodies 28 on one side of the telescopic rod of the sixth cylinder 21, so that the sixth cylinder 21 can simultaneously push the two sets of packaged hinge bodies 28 into the temporary storage plate 23.
[0048] Furthermore, refer to Figure 7 The finished product packing device X7 includes a fourth conveyor belt 24, a fifth conveyor belt 25, a second weighing device 26, and a sixth conveyor belt 27 arranged in sequence. The fourth conveyor belt 24 is used for feeding the packaging boxes 29, the fifth conveyor belt 25 is used for storing the packaged boxes 29, the second weighing device 26 is used for weighing and detecting the packaged boxes 29 after they have been filled, and the sixth conveyor belt 27 is used for transporting the packaged boxes 29 after they have been filled. The finished product transfer device X8 can transfer the two sets of packaged hinge bodies 28 in the temporary storage plate 23 to the packaged boxes 29 on the fifth conveyor belt 25.
[0049] Workflow:
[0050] The process of the finished product discharge device X6: The packaged finished product after being packaged by the bagging device X5 has two sets of hinge bodies 28 and bolts. The bagging device X5 transports the packaged finished product to the first weighing device 18 for weighing. The first weighing device 18 detects whether the packaged finished product has two sets of hinge bodies 28 and bolts. The first weighing device 18 transports the qualified packaged finished product to the third conveyor belt 19. The third guide plate 20 set on the third conveyor belt 19 can prevent the packaged finished product from shifting. The third conveyor belt 19 continuously transports the packaged finished product. When the two sets of third sensors 22 detect that there are two sets of packaged finished products at the extension rod of the sixth cylinder 21, the sixth cylinder 21 is started. The extension rod of the sixth cylinder 21 pushes the two sets of packaged finished products to the temporary storage plate 23 to wait for transfer.
[0051] The process of the finished product packing device X7 is as follows: The fourth conveyor belt 24 continuously transports the packaging box 29. When the packaging box 29 is transported to the fifth conveyor belt 25, the fifth conveyor belt 25 stops transporting. The finished product transfer device X8 continuously transfers the packaged finished products on the temporary storage plate 23 into the packaging box 29. After a set number of packaged finished products have been transferred, the fifth conveyor belt 25 starts transporting again, sending the packaging box 29 with packaged finished products into the second weighing device 26 for weighing. The second weighing device 26 detects whether there is a sufficient amount of packaged finished products in the packaging box 29. Finally, the second weighing device 26 sends the packaging box 29 into the sixth conveyor belt 27, which continuously transports the packaging box 29 outward.
