[0046] The filling equipment is a type of product in the packaging machine and is used to divide and fill the produced materials into each filling container. The materials can be liquid, powdery, paste-like, etc. During actual filling, each filling container is transported to the lower part of the filling head through a conveying device, and then filling is carried out through the filling head. During transportation, a limiting structure is required to limit the filling container to prevent it from tipping over or being misaligned, which may affect the filling process. In the related art, it is difficult for the conveying device to adapt to filling containers of different sizes. When the filling containers are different, the entire limiting structure needs to be disassembled and replaced.

[0047] The main purpose of the present utility model is to propose a conveying device and a filling equipment, aiming to at least solve the problems in the related art that it is difficult for the conveying device to adapt to filling containers of different sizes, and when the filling containers are different, the entire limiting structure needs to be disassembled and replaced, etc.

[0048] Please refer to Figure 1 , a conveying device 100 proposed by the present utility model is applied to a filling equipment 1000 and includes a base 1, a conveyor belt 2, and a limiting component 3. The conveyor belt 2 is arranged on the base 1 and extends horizontally. The limiting component 3 is arranged on the base 1 and includes two limiting rods 31 located above the conveyor belt 2 and extending horizontally. The two limiting rods 31 are arranged at intervals longitudinally to define a limiting space, and the distance between the two limiting rods 31 is adjustable.

[0049] In the technical solution of the present utility model, the conveyor belt 2 extends horizontally. The limiting component 3 includes two limiting rods 31 located above the conveyor belt 2 and extending horizontally. The two limiting rods 31 are arranged at intervals longitudinally to define a limiting space, and the distance between the two limiting rods 31 is adjustable. Thus, before filling, according to the size of the filling container, the distance between the two limiting rods 31 is adjusted so that the distance between the two limiting rods 31 is slightly larger than the filling container. During filling, the filling container is transported horizontally through the conveyor belt 2, and the limiting space between the two limiting rods 31 limits the movement range of the filling container, ensuring the normal progress of filling. The overall structure can adapt to filling containers of different sizes.

[0050] There are various methods to adjust the distance between the two limiting rods 31. For example, two threaded rods can be used to control the horizontal movement of the two limiting rods 31 respectively to adjust the distance, or a bidirectional threaded rod can be directly used to simultaneously control the relative or opposite movement of the two limiting rods 31 to adjust the distance. In the embodiment of the present utility model, please refer to Figure 1 and Figure 2 , the limiting component 3 further includes at least two support blocks 32 arranged on the base 1. One end of the support block 32 is provided with two first clamping arms 321 arranged at intervals in the vertical direction and connected by screws. On the opposite sides of the two first clamping arms 321, first receiving grooves are provided, and the two first receiving grooves form a first installation groove. On the opposite sides of the two limiting rods 31, sliding rods 33 are provided, and the sliding rods 33 are slidably installed longitudinally in the corresponding first installation grooves. Thus, when it is necessary to adjust the distance between the two limiting rods 31, the tightness of the two first clamping arms 321 is adjusted by screws so that the sliding rods 33 can slide in the first installation grooves. After sliding to a suitable position, the two first clamping arms 321 are tightened by screws to fix the sliding rods 33 and keep the limiting rods 31 fixed. Actually, when adjusting, the two limiting rods 31 can be adjusted, or only one of the limiting rods 31 can be adjusted. Compared with adjusting the limiting rods 31 through a threaded structure, when the size difference between the two filling containers before and after is relatively large, that is, the movement stroke of the limiting rods 31 will be relatively large, the threaded structure has low efficiency during adjustment. And because the limiting rods 31 are applied on the conveyor belt 2 and are usually set relatively long, that is, the overall is relatively heavy, the threaded structure is prone to damage when bearing weight for a long time.

[0051] It can be understood that the suitable limiting positions for filling containers of different shapes are different. For example, if a container is relatively tall and the limiting rod 31 limits the position near the bottom of the container, it will cause the filling container to be prone to tipping. Therefore, in the technical solution of the present invention, the support block 32 is movably arranged relative to the base 1 in the vertical direction, or the limiting rod 31 is movably arranged relative to the support block 32 in the vertical direction. In this way, by driving the movement of the limiting rod 31 through the movement of the support block 32 or directly through the movement of the limiting rod 31, the height of the limiting rod 31 can be changed, so as to be able to adapt to filling containers of different shapes, perform better limiting, and reduce the possibility of tipping.

[0052] Specifically, in this embodiment, please refer to Figure 2 , at the other end of the support block 32, there are two second clamping arms 322 arranged at intervals in the transverse direction and connected by screws. On the opposite sides of the two second clamping arms 322, there are second receiving grooves, and the two second receiving grooves form a second installation groove. On the base 1, there is also a support rod 34 extending in the vertical direction. The support block 32 is slidably installed on the support rod 34 in the vertical direction through the second installation groove. When it is necessary to adjust the height of the limiting rod 31, loosen the two second clamping arms 322 by screws, so that the support block 32 can slide relative to the support rod 34. After driving the limiting rod 31 to a suitable height through the sliding of the support block 32, then tighten the two second clamping arms 322 by screws to fix the support block 32 and the support rod 34, thereby keeping the height of the limiting rod 31 fixed. The way the support block 32 slides in the vertical direction is not limited to this. In another embodiment, a threaded structure can be used to drive the support block 32 to move up and down.

[0053] For the conveyor belt 2, at least two shafts are required, namely a driving shaft 4 and a driven shaft 5. The driving shaft 4 drives the conveyor belt 2 to rotate, and the driven shaft 5 plays a supporting role. In the embodiment of the present invention, please refer to Figure 1 and Figure 3 , the conveying device 100 further includes a driving shaft 4 and a driven shaft 5 that extend longitudinally and are rotatably arranged on the base 1. The driving shaft 4 and the driven shaft 5 are respectively arranged at both ends of the inner cavity of the conveyor belt 2. The driven shaft 5 is movably arranged relative to the base 1 in the transverse direction. With such an arrangement, the driven shaft 5 can move in the transverse direction, thereby changing the distance between the driven shaft 5 and the driving shaft 4. During long-term use, the conveyor belt 2 will inevitably become loose due to wear, and it is difficult to ensure the stability of transporting the filling containers. By changing the distance between the driven shaft 5 and the driving shaft 4, the conveyor belt 2 can be tensioned to ensure the stability of transportation.

[0054] There are various ways to control the lateral movement of the driven shaft 5. In some embodiments, a support plate 11 is longitudinally provided on the base 1; the conveying device 100 further includes an adjusting assembly 6, the adjusting assembly 6 includes a screw rod 61, a sleeve 62 and a nut 63, the screw rod 61 extends laterally and one end thereof penetrates through the support plate 11, the sleeve 62 is connected to one end of the screw rod 61 facing the driving shaft 4, the sleeve 62 is sleeved on the end of the driven shaft 5, the nut 63 is threadedly connected to the screw rod 61 and abuts against the side of the support plate 11 away from the sleeve 62; thus arranged, when it is necessary to adjust the distance between the driven shaft 5 and the driving shaft 4 to tension the conveyor belt 2, rotate the nut 63, through the abutment of the nut 63 and the support plate 11, the screw rod 61 moves laterally away from the driving shaft 4, thereby driving the driven shaft 5 away from the driving shaft 4 to tension the conveyor belt 2. In some embodiments, a plurality of laterally spaced mounting holes may be provided on the base 1, and the mounting holes are adapted to the above-mentioned sleeve 62. When tensioning, by installing the sleeve 62 in the mounting holes at different positions, the distance between the driving shaft 4 and the driven shaft 5 can be changed.

[0055] It can be understood that since the driven shaft 5 needs to support the conveyor belt 2, the position where the sleeve 62 is connected to it is the end of the driven shaft 5. If only one of the screw rod 61, the sleeve 62 and the nut 63 is provided to adjust one end, during the actual adjustment process, it is very easy to cause the driven shaft 5 to tilt, affecting the support effect on the conveyor belt 2; therefore, in this embodiment, two adjusting assemblies 6 are provided to adjust the two ends of the driven shaft 5 respectively; thus, the two ends of the driven shaft 5 can be adjusted by the two screw rods 61, and finally the stability of the driven shaft 5 can be maintained. For the threaded structure, there is a certain gap between the threads, so that there can be a small angle of inclination between the screw rod 61 and the base 1. The adjustment of the driven shaft 5 is to make up for wear, and the distance to be adjusted itself is very small. The two screw rods 61 will not interfere with each other and can be adjusted normally.

[0056] There are various connection methods between the driven shaft 5 and the sleeve 62. In this embodiment, please refer to Figure 4, the driven shaft 5 includes an outer wheel 51, an inner shaft 52, a flange bearing 53 and a snap ring 54. The outer wheel 51 is in driving connection with the inner cavity of the conveyor belt 2. The inner shaft 52 is rotatably arranged in the inner cavity of the outer wheel 51 and penetrates through the outer wheel 51 at both ends. The flange bearing 53 is sleeved on the outer surface of the inner shaft 52. The outer ring of the flange bearing 52 is supported on the inner side of the outer wheel 51 and abuts against the end of the outer wheel 51. The snap ring 54 is arranged on the inner shaft and abuts against the side of the flange bearing 53 away from the outer wheel 51. Among them, the inner shaft 52 is fixedly connected with the sleeve 62. With such a setting, the outer wheel 51 supports the conveyor belt 2, and the inner shaft 52 supports the outer wheel 51 through the flange bearing 63. The snap ring 54 keeps the flange bearing 53 fixed with the outer wheel 51 and the inner shaft 52. Fixing the inner shaft 52 with the sleeve 62 can fix the entire driven shaft 5. In another embodiment, the driven shaft 5 can be directly rotatably connected to the sleeve 62 through a bearing.

[0057] For the convenience of the user to adjust, the support plate 11 extends towards the outside of the base 11. The end of the inner shaft 52 of the driven shaft 5 penetrates to the outside of the base 1. A long strip-shaped sliding hole 12 adapted to the inner shaft 52 is provided on the base 1. With such a setting, the screw 61 and the nut 63 can be located outside the conveyor belt 2 and the base 1, and the adjustment is more convenient.

[0058] The present utility model also proposes a filling device 1000. Please refer to Figure 1 and Figure 5 . The filling device 1000 includes at least one filling head 7 and a conveying device 100. The specific structure of the conveying device 100 refers to the above-mentioned embodiment. Since the filling device 1000 adopts all the technical solutions of the above-mentioned all embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be elaborated one by one here. Among them, the filling head 7 is located above the conveyor belt 2.

[0059] In order to be able to adapt to filling containers of different heights, in the embodiment of the present application, the filling device 1000 further includes a bracket 8 arranged on one side of the base 1 in the longitudinal direction. The filling head 7 is movably arranged relative to the bracket 8 in the up and down direction. With such a setting, the height of the filling head 7 can be adjusted by the movement of the filling head 7 relative to the bracket 8, so as to adapt to different filling containers.

[0060] There are various ways to adjust the filling head 7. In this embodiment, a chute 81 extending in the vertical direction is provided on one side of the bracket 8 facing the filling head 7; the filling device 1000 further includes a connecting member 9 slidably mounted in the chute 81, and the filling head 7 is provided on the bracket 8. In this way, the height change of the filling head 7 is driven by the sliding of the connecting member 9 in the chute 81. In another embodiment, the movement of the filling head 7 can also be driven by a threaded structure.

[0061] It can be understood that the connecting member 9 needs to be fixed after sliding in the chute 81, and there are various fixing methods. For example, a tightening screw can be provided on the connecting member 9, and after adjustment, it is tightened and fixed by the tightening screw. For another example, a clamping block and a clamping groove can be provided on the side wall of the connecting member 9 and the chute 81, and multiple clamping blocks and clamping grooves need to be provided on the side wall of the chute 81. By cooperating at different positions, the connecting member 9 and the filling head 7 can be fixed at different heights.

[0062] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
