[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0028] like Figures 1 to 4 As shown, the roller chain conveyor is composed of single-sided conveying lines on both sides, namely the first side roller chain conveying line 1 and the second side roller chain conveying line 2. The first side roller chain conveying line 1 and the second side roller chain conveying line 2 are relatively mirror-imaged, and the conveying heights on both sides are the same. The first side roller chain conveying line 1 and the second side roller chain conveying line 2 are both driven by a driving mechanism. The guide mechanism is arranged between the first side roller chain conveying line 1 and the second side roller chain conveying line 2. The guide mechanism plays a guiding role. The second side roller chain conveying line 2 can, under the action of the guide mechanism, move close to or away from the first side roller chain conveying line 1 in the width direction of the conveying line. Horizontal displacement. During the horizontal displacement process, the straight-line distance between the first side roller chain conveyor line body 1 and the second side roller chain conveyor line body 2 changes synchronously, that is, the width of the roller chain conveyor is changed, so that it can adapt to pallets of different sizes and widths. The positioning mechanism is used to limit or release the movable state of the second side roller chain conveyor line body 2 relative to the guide mechanism, that is, through the positioning mechanism, to control whether the second side roller chain conveyor line body 2 can be horizontally displaced relative to the first side roller chain conveyor line body 1 through the guide mechanism, and when the second side roller chain conveyor line body 2 moves to the preset position, its position can be fixed by the positioning mechanism to prevent it from moving horizontally during the pallet conveying process.

[0029] In some embodiments, as Figures 1 to 4 As shown, the guide rod 3 is a horizontal round rod with its length direction being the width direction of the roller chain conveyor. One end of the guide rod 3 is fixedly connected through a guide rod fixing seat 4. The guide rod fixing seat 4 is fixedly connected to the lower end of the first side roller chain conveyor line body 1 and the upper end of one side of the base 6 through a first connecting piece 5. The base 6 is a supporting frame formed by the profile. The base 6 is fixedly arranged relative to the ground. The bearing seat 7 is fixedly connected to the upper end of the other side of the base 6. A bearing is pre-sleeved in the bearing seat 7. The sliding seat 8 is fixedly arranged under the second side roller chain conveyor line body 2. The other end of the guide rod 3 passes through the sliding seat 8 and the bearing seat 7. When the second side roller chain conveyor line body 2 is relatively displaced relative to the first side roller chain conveyor line body 1, the sliding seat 8 is displaced relative to the guide rod 3, and the guide rod 3 guides the displacement horizontally in the width direction. The guide rod 3, the guide rod fixing seat, the bearing seat 7 and the sliding seat 8 together constitute a guiding mechanism with horizontal guiding function.

[0030] In some embodiments, as Figure 2 and Figure 6 As shown, the positioning mechanism is a locking bearing 9, which is fixedly connected to the sliding seat 8. Specifically, the locking bearing 9 can be passed through and fixed to the sliding seat 8. The locking bearing 9 can adjust the center diameter by applying external force. The guide rod 3 passes through the locking bearing 9. When it is necessary to move the second side roller chain conveyor line body 2, the locking bearing 9 is adjusted to a loose mode. At this time, the locking bearing 9 can move horizontally along the guide rod 3 relative to the first side roller chain conveyor line body 1 along with the second side roller chain conveyor line body 2; when it is necessary to fix the position of the second side roller chain conveyor line body 2, the locking bearing 9 is adjusted to a tight mode. At this time, the locking bearing 9 is tightly connected to the guide rod 3, and the second side roller chain conveyor line body 2 is fixed relative to the first side roller chain conveyor line body 1.

[0031] In some embodiments, as Figure 2 and Figure 6 As shown, the positioning mechanism further includes an adjusting handle 10, which is operably connected to the locking bearing 9. The tightness of the locking bearing 9 can be adjusted by twisting the adjusting handle 10, which is convenient for operation.

[0032] In some embodiments, as Figure 6 As shown, the structures of the first side roller chain conveyor line body 1 and the second side roller chain conveyor line body 2 are mirror-image structures, both of which include a line body body 11, a roller chain 12, a guide wheel 13 and a roller chain drive wheel 14, wherein the line body body 11 is mainly composed of a conveying profile, and the guide wheels 13 are freely arranged at both ends of the line body body. The roller chain drive wheel 14 is arranged below one end of the line body body 11 through a connecting plate 15. A guide wheel 13 is also provided above the roller chain drive wheel 14. The roller chain 12 is wound around the guide wheel 13 and the roller chain drive wheel 14, and the roller chain drive wheel 14 is driven to rotate by a driving mechanism, thereby driving the roller chain 12 to run, so that the first side roller chain conveyor line body 1 and the second side roller chain conveyor line body 2 are in operation.

[0033] In some embodiments, as Figure 1 and Figure 5The driving mechanism includes a motor 16, a motor driving wheel 17, a transmission belt 18 and a transmission shaft 19. The motor 16 is fixedly connected to the first side roller chain conveyor line body 1 through the motor mounting plate 20. The motor 16 can be arranged on a side close to the first side roller chain conveyor line body 1. The head end of the motor 16 is provided with a motor driving wheel 17. The transmission belt 18 is sleeved between the motor driving wheel 17 and the roller chain driving wheel 14. The motor driving wheel 17 can be connected to the roller chain driving wheel 14 of the first side roller chain conveyor line body 1 through the transmission belt 18, and the power is transmitted to the roller chain driving wheel 14 of the second side roller chain conveyor line body 2 through the transmission shaft 19, so that the motor 16 synchronously drives the roller chain driving wheels 14 on both sides to run synchronously.

[0034] In some embodiments, as Figure 5 and Figure 8 The transmission shaft 19 is a hexagonal square shaft, and the roller chain drive wheel 14 has a hexagonal through hole 1401. The size of the hexagonal through hole 1401 matches the cross-section of the transmission shaft 19. The transmission shaft 19 is connected to the roller chain drive wheel 14 through the hexagonal through hole 1401. When the second-side roller chain conveyor line body 2 is horizontally displaced relative to the first-side roller chain conveyor line body 1, the roller chain drive wheel 14 of the second-side roller chain conveyor line body 2 will also be horizontally displaced relative to the transmission shaft 19. The use of a hexagonal square shaft in combination with the hexagonal through hole 1401 can ensure that its horizontal displacement is not restricted, and can also ensure that during its axial rotation, it can synchronously drive the roller chain drive wheel 14 to rotate.

[0035] In some embodiments, as Figure 7 and Figure 9 As shown, it includes a tensioning mechanism, which is used to adjust the tensioning degree of the roller chain 12. The tensioning mechanism includes a tensioning wheel 21, a tensioning wheel seat 22, a fixing part 23 and a tensioning bolt 24. The tensioning wheel 21 is freely set on the tensioning wheel seat 22. The tensioning wheel 21 can replace the guide wheel 13 on the side away from the roller chain driving wheel 14. The fixing part 23 is fixedly connected to the line body 11. The fixing part 23 is provided with a through hole with a thread. The tensioning bolt 24 is screwed into the fixing part 23 in the length direction along the conveying direction of the roller chain conveyor. At the same time, one end of the tensioning bolt 24 is fixedly connected to the tensioning wheel seat 22. The roller chain 12 is passed around the tensioning wheel 21, the guide wheel 13 and the roller chain driving wheel 14. By adjusting the unscrewing position of the tensioning bolt 24 relative to the fixing part 23, the tensioning wheel 21 can be driven to move horizontally relative to the line body 11, thereby adjusting the tensioning degree of the roller chain 12.

[0036] In the present application, if it is necessary to adjust the distance between the first side roller chain conveyor line 1 and the second side roller chain conveyor line 2, first adjust the locking bearing 9 to a loose state by adjusting the handle 10, so that the second side roller chain conveyor line 2 can be moved relative to the guide rod 3. The movement process can be done by hand pushing to apply a horizontal force to the second side roller chain conveyor line 2. When the second side roller chain conveyor line 2 is horizontally displaced to a position that meets the width size of the pallet to be transported, adjust the locking bearing 9 to a tight state by adjusting the handle 10 to fix the position of the second side roller chain conveyor line 2 relative to the guide rod 3.
