DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] See also Figure 1-4 A device for automatically unloading formed cartons comprises a first conveyor belt 1, a second conveyor belt 2 and a base 8, a support leg 9 is fixedly mounted on the base 8, a first loading tray 10 is mounted above the support leg 9, a driving motor 13 is fixedly mounted on the top surface of the first loading tray 10, a pushing tray 16 is transmission-connected below the driving motor 13, a straight rod 20 and an arc block are fixedly mounted on the bottom surface of the pushing tray 16, a transmission tray 14 is arranged on one side of the pushing tray 16, a rotatable rotating rod 15 is mounted inside the first loading tray 10, a feeding tray 6 is fixedly mounted on the top surface of the rotating rod 15, four square grooves are arranged on the top surface of the feeding tray 6, and the four square grooves are distributed in a circular array on the top surface of the feeding tray 6.

[0024] For further information, see Figure 2 A docking groove 17 is provided on the side wall of the second loading tray 11 on the side close to the second conveyor belt 2, and a portion of the second conveyor belt 2 is located inside the protective plate 7. By setting the docking groove 17 and setting a portion of the second conveyor belt 2 inside the docking groove 17, the carton body 5 can be smoothly transported out of the device by the second conveyor belt 2 when it is driven by the feeding tray 6 to the top of the docking groove 17.

[0025] For further information, see Figure 4 An arc groove 18 and a straight groove 19 are provided on the outer wall of the transmission disk 14. The arc groove 18 is adapted to the arc block, and the straight groove 19 is adapted to the straight rod 20. The number of the arc groove 18 and the straight groove 19 is four. By setting the arc groove 18 and the straight groove 19, and setting the arc groove 18 to be adapted to the arc block, and the straight groove 19 to be adapted to the straight rod 20, when the push disk 16 drives the straight rod 20 and the arc block to rotate, the straight rod 20 will resist the straight groove 19 to drive the transmission disk 14 to rotate, and then the arc block will rotate to the inside of the arc groove 18 to prevent the transmission disk 14 from generating unnecessary rotation, until the straight rod 20 rotates to the inside of the straight groove 19 again, the transmission disk 14 will be driven to rotate again.

[0026] In specific implementation, when using a conventional unloading device to unload the formed cartons, the unloading speed cannot be effectively controlled, which makes the subsequent stacking or further processing of the cartons more difficult. In this embodiment, the carton body 5 is first conveyed by the first conveyor belt 1 until it is close to the edge of the feed tray 6. If the square groove on the surface of the feed tray 6 faces the first conveyor belt 1, the carton body 5 will fall onto the top of the second loading tray 11. After the carton body 5 falls onto the top of the second loading tray 11, the driving motor 13 will drive the push plate 16 to rotate. After the push plate 16 rotates, the straight rod 20 installed at the bottom of the push plate 16 and the arc The arc groove 18 and the straight groove 19 opened on the outer wall of the shape block and the transmission disk 14 cooperate with each other, so that the transmission disk 14 can only rotate ninety degrees at a time after the push disk 16 rotates one circle, and a rotating rod 15 is connected between the feeding disk 6 and the transmission disk 14, so the feeding disk 6 will also rotate synchronously after the transmission disk 14 rotates, which makes it possible for the carton body 5 transmitted above the first conveyor belt 1 to be smoothly transferred from the square groove opened in the feeding disk 6 to the top of the second conveyor belt 2. At the same time, the transmission speed of the carton body 5 is controlled to prevent too many carton bodies 5 from passing through the top of the second conveyor belt 2 in the same time period, so that the carton body 5 can be unloaded at a uniform speed.

[0027] By setting a straight rod 20 and an arc block fixedly installed on the bottom of the push plate 16, and setting an arc groove 18 and a transmission plate 14 on the outer wall of the straight rod 20, the transmission plate 14 can only rotate ninety degrees after the push plate 16 rotates one circle. Finally, a rotating rod 15 is connected between the transmission plate 14 and the feeding plate 6, so that the feeding plate 6 will rotate synchronously with the transmission plate 14, so that the carton body 5 can complete uniform speed unloading, which is convenient for the subsequent packaging or stacking of the carton body 5.

[0028] In addition, a second side guardrail 4 is fixedly installed on the top surface of the first conveyor belt 1, and a first side guardrail 3 is arranged on the top surface of the second conveyor belt 2. The presence of the first side guardrail 3 and the second side guardrail 4 prevents the carton body 5 from falling easily when it is on the top surface of the second conveyor belt 2.

[0029] In addition, a protective plate 7 is fixedly installed at the edge of the second loading tray 11, and the protective plate 7 is adapted to the feeding tray 6. By setting the protective plate 7 and adapting the protective plate 7 to the feeding tray 6, the carton body 5 will not easily fall out of the device during the process of transferring the carton body 5 by the feeding tray 6, thereby increasing the stability of the device operation.

[0030] Working principle: When using conventional unloading devices to unload formed cartons, the unloading speed cannot be effectively controlled, which makes the subsequent stacking or further processing of cartons more difficult. In this embodiment, the carton body 5 is first conveyed by the first conveyor belt 1 until it is close to the edge of the feed tray 6. If the square groove on the surface of the feed tray 6 faces the first conveyor belt 1, the carton body 5 will fall onto the second loading tray 11. After the carton body 5 falls onto the second loading tray 11, the driving motor 13 will drive the push plate 16 to rotate. After the push plate 16 rotates, the straight rod 20 installed at the bottom of the push plate 16 and the arc The arc groove 18 and the straight groove 19 opened on the outer wall of the shape block and the transmission disk 14 cooperate with each other, so that the transmission disk 14 can only rotate ninety degrees at a time after the push disk 16 rotates one circle, and a rotating rod 15 is connected between the feeding disk 6 and the transmission disk 14, so the feeding disk 6 will also rotate synchronously after the transmission disk 14 rotates, which makes it possible for the carton body 5 transmitted above the first conveyor belt 1 to be smoothly transferred from the square groove opened in the feeding disk 6 to the top of the second conveyor belt 2. At the same time, the transmission speed of the carton body 5 is controlled to prevent too many carton bodies 5 from passing through the top of the second conveyor belt 2 in the same time period, so that the carton body 5 can be unloaded at a uniform speed.

[0031] In addition, a support block 12 is fixedly mounted on the top surface of the first loading tray 10 , and a second loading tray 11 is fixedly mounted on the top surface of the support block 12 .

[0032] By setting a straight rod 20 and an arc block fixedly installed on the bottom of the push plate 16, and setting an arc groove 18 and a transmission plate 14 on the outer wall of the straight rod 20, the transmission plate 14 can only rotate ninety degrees after the push plate 16 rotates one circle. Finally, a rotating rod 15 is connected between the transmission plate 14 and the feeding plate 6, so that the feeding plate 6 will rotate synchronously with the transmission plate 14, so that the carton body 5 can complete uniform speed unloading, which is convenient for the subsequent packaging or stacking of the carton body 5.
