Description

Technical Field

[0001] This utility model belongs to the field of conveyor technology, specifically relating to a conveyor line with lifting function. Background Technology

[0002] In many fields such as industrial production and logistics transportation, conveyor lines are key equipment for achieving efficient material handling and transfer. Traditional conveyor lines typically have a relatively fixed structure. Once the height of the front and rear ends of the conveyor belt is determined during operation, it is difficult to change, and the entire conveyor belt is basically at the same horizontal level.

[0003] In real-world work scenarios, different production processes and work requirements often necessitate that items be transported to different heights. For example, in some assembly lines, items may need to be transported to a lower height for preliminary processing before being moved to a higher height for subsequent assembly. In warehousing and logistics, goods may need to be transported to shelves at different heights for storage. However, existing conveyor lines, due to their insufficient height adjustment capabilities, cannot flexibly adapt to these diverse work requirements. Changing the transport height often requires redesigning and installing a new conveyor system, which not only consumes significant manpower, material resources, and time costs but also leads to production interruptions, severely impacting production efficiency and economic benefits.

[0004] Therefore, developing a conveyor line that can freely change the height of the middle position of the conveyor belt without changing the height of the front and end of the conveyor belt, thereby meeting different working requirements, is of great practical significance. Utility Model Content

[0005] The purpose of this invention is to provide a conveyor line with lifting function, which can freely change the height of the middle position of the conveyor belt without changing the height of the front end and the end end of the conveyor belt, thereby moving the items on the conveyor belt to different heights to meet different work requirements.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A conveyor line with lifting function includes a lower support, two side plates fixedly connected to the upper side of the lower support, a plurality of rotating rollers disposed between the two side plates, a conveyor belt being drivenly connected to the outer side of the plurality of rotating rollers, the rotating rollers located at the front and rear ends being the main drive rollers, and the remaining rotating rollers being the intermediate rollers, a main drive motor being fixedly connected to the outer side of the side plates, and the main drive motor being drivenly connected to one of the main drive rollers;

[0008] The intermediate rollers are divided into one set of movable rollers and two sets of fixed rollers, with the movable rollers located between the two sets of fixed rollers.

[0009] Multiple sets of lifting supports are fixedly connected to the side plate. The number of lifting supports is the same as the number of movable rollers. The movable rollers are installed on the lifting supports.

[0010] The side plate is also fixedly connected to a conveyor belt tensioning unit that is connected to the conveyor belt body for transmission.

[0011] Limiting rollers are installed on both sides of the side plate and on the two sets of fixed rollers.

[0012] Furthermore, the lifting support includes two lower sliding rails that are respectively fixedly connected to the lower sides of the two side plates. A sliding plate is vertically slidably connected inside the lower sliding rail. The movable roller is installed on the sliding plate. A first drive motor is fixedly connected to the outer side of the lower sliding rail. A first screw that is threadedly connected to the sliding plate is fixedly connected to the output end of the first drive motor.

[0013] Furthermore, a lifting assembly located below the movable roller is fixedly connected to the lower support. Both ends of the movable roller are rotatably connected to a rotating shaft mounting block, which is detachably mounted on the slide plate or the lifting assembly.

[0014] Furthermore, the lifting assembly includes a second electric push rod fixedly connected to the lower support, a main lifting plate fixedly connected to the piston rod of the second electric push rod, a second mounting seat fixedly connected to the main lifting plate, a first mounting seat fixedly connected to the slide plate, and the rotating shaft mounting block can be snapped into the first mounting seat or the second mounting seat.

[0015] Furthermore, two additional lifting plates are slidably connected to the main lifting plate, and multiple third mounting seats are fixedly connected to the upper side of each of the two additional lifting plates. The rotating shaft mounting block can be snapped into the interior of the third mounting seat. A second drive motor is fixedly connected to the end of the main lifting plate, and a meshing gear is fixedly connected to the output end of the second drive motor. A meshing rack that meshes with the meshing gear is fixedly connected to the outer side of the additional lifting plates.

[0016] The technical effects achieved by this utility model are as follows:

[0017] This utility model discloses a conveyor line with lifting function. By adjusting the height of the movable roller, the height of the middle position of the conveyor belt can be adjusted, thereby forming two working planes with different heights on the upper side of the conveyor belt. Without changing the height of the front end and the end end of the conveyor belt, the height of the middle position of the conveyor belt can be freely changed, thus enabling the items on the conveyor belt to be moved to different heights to meet different work needs.

[0026] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0027] like Figures 1-6As shown, a conveyor line with lifting function includes a lower support 1. Two side plates 2 are fixedly connected to the upper side of the lower support 1. Multiple rotating rollers 3 are arranged between the two side plates 2. A conveyor belt 6 is drivenly connected to the outer side of the multiple rotating rollers 3. Among the multiple rotating rollers 3, the rotating rollers 3 located at the front and rear ends are the main drive rollers, and the remaining rotating rollers 3 are intermediate rollers. A main drive motor is fixedly connected to the outer side of the side plates 2. The main drive motor is drivenly connected to one of the main drive rollers. At this time, the main drive motor drives the main drive roller to rotate, which drives the conveyor belt 6 to move, and drives the items on the upper side of the conveyor belt 6 to move.

[0028] In this technical solution, the multiple intermediate rollers are divided into one set of movable rollers and two sets of fixed rollers. The movable rollers are located between the two sets of fixed rollers. The fixed rollers are rotating rollers 3 that can only rotate on the side plate 2 and cannot be moved. The movable rollers are rotating rollers 3 that can be lifted and moved on the side plate 2.

[0029] Multiple sets of lifting supports 4 are fixedly connected to the side plate 2. The number of lifting supports 4 is the same as the number of movable rollers, so that the lifting supports 4 and the movable rollers can be aligned one-to-one. The movable rollers are installed on the lifting supports 4. At this time, the height of the movable rollers can be adjusted by activating the lifting supports 4. After the height of the movable rollers is adjusted, the height of the middle position of the conveyor belt 6 can be adjusted, so that two working planes of different heights can be formed on the upper side of the conveyor belt 6. Without changing the height of the front end and the height of the end of the conveyor belt 6, the height of the middle position of the conveyor belt 6 can be freely changed, so that the items on the conveyor belt 6 can be moved to different heights to meet different work needs.

[0030] like Figures 1-2 As shown, in order to adjust the tension of the conveyor belt 6, a conveyor belt tensioning unit 5 is fixedly connected to the side plate 2 and is driven by the conveyor belt 6. The conveyor belt tensioning unit 5 includes an auxiliary plate 10 fixedly connected to the lower side of the two side plates 2 respectively. Three fixed tension rollers 11 are rotatably connected between the two auxiliary plates 10. Two movable tension rollers 12 are arranged on the lower side of the three fixed tension rollers 11. A first electric push rod 13 is fixedly connected to each of the two auxiliary plates 10. The piston rod of the first electric push rod 13 is fixedly connected to a connecting ring that is rotatably connected to the movable tension roller 12. The conveyor belt 6 passes through the fixed tension roller 11, the movable tension roller 12, the fixed tension roller 11, the movable tension roller 12, and the fixed tension roller 11 in sequence. By activating the first electric push rod 13 to adjust the position of the movable tension roller 12, the tension of the conveyor belt 6 can be adjusted.

[0031] like Figures 1-6As shown, horizontal moving groups 9 are fixedly connected to both sides of the side plate 2 and to the two sets of fixed rollers. Limiting rollers 30 are installed on the horizontal moving groups 9. At this time, the position of the bending point of the conveyor belt 6 can be limited by the limiting rollers 30, and the length of the conveyor belt 6 in a horizontal setting on the upper side of the fixed rollers can be controlled.

[0032] The horizontal moving assembly 9 includes a horizontal guide rail 26 fixedly connected to the side plate 2. A slider 29 is slidably connected inside the horizontal guide rail 26. The limiting roller 30 is rotatably connected to the slider 29. A third drive motor 27 is fixedly connected to one end of the horizontal guide rail 26. A second screw 28 threadedly connected to the slider 29 is fixedly connected to the output end of the third drive motor 27. By starting the third drive motor 27, the slider 29 can be moved to adjust the horizontal position of the limiting roller 30, and the position of the limiting roller 30 can be made more stable after the adjustment is completed.

[0033] like Figure 1 and Figure 3 As shown, the lifting support 4 includes two sliding rails 14 that are fixedly connected to the lower sides of the two side plates 2 respectively. A slide plate 15 is vertically slidably connected inside the sliding rail 14. A movable roller is installed on the slide plate 15. The height of the movable roller can be adjusted by moving the slide plate 15. A first drive motor 17 is fixedly connected to the outside of the sliding rail 14. A first screw 18 that is threadedly connected to the output end of the first drive motor 17 is fixedly connected to the slide plate 15. At this time, the lifting and lowering of the slide plate 15 can be controlled by starting the first drive motor 17.

[0034] like Figure 1 and Figures 3-4 As shown, a lifting component 7 located on the lower side of the movable roller is fixedly connected to the lower bracket 1. Both ends of the movable roller are rotatably connected to a rotating shaft mounting block 8. The rotating shaft mounting block 8 can be detachably installed on the slide plate 15 or the lifting component 7. The preferred installation method is snap-fit ​​or magnetic attraction.

[0035] At this time, the multiple movable rollers are divided into two groups. One group consists of integral movable rollers that are opposite to the lifting assembly 7, and the other group consists of free movable rollers that are offset from the lifting assembly 7. At this time, the lifting assembly 7 is activated to lift the rotating shaft mounting block 8, which can adjust the height of the middle working plane of the conveyor belt 6 and ensure the accuracy of the multiple integral movable rollers. Then, the height of the free movable rollers is adjusted to support the inclined part of the conveyor belt 6.

[0036] The lifting assembly 7 includes a second electric push rod fixedly connected to the lower bracket 1. A main lifting plate 19 is fixedly connected to the piston rod of the second electric push rod. A second mounting seat 20 is fixedly connected to the main lifting plate 19. A first mounting seat 16 is fixedly connected to the slide plate 15. The rotating shaft mounting block 8 can be snapped into the first mounting seat 16 or the second mounting seat 20. At this time, by activating the second electric push rod to drive the main lifting plate 19 to rise and fall, the rotating shaft mounting block 8 snapped into the second mounting seat 20 can be pushed upward, so that the rotating shaft mounting block 8 is separated from the first mounting seat 16, thereby completing the switching of the rotating shaft mounting block 8 between the lower rail 14 and the lifting assembly 7 in a relatively simple way.

[0037] Two auxiliary lifting plates 21 are slidably connected to the main lifting plate 19. Multiple third mounting seats 22 are fixedly connected to the upper side of each of the two auxiliary lifting plates 21. The rotating shaft mounting block 8 can be snapped into the interior of the third mounting seat 22. A second drive motor 23 is fixedly connected to the end of the main lifting plate 19. A gear 24 is fixedly connected to the output end of the second drive motor 23. A rack 25 that meshes with the gear 24 is fixedly connected to the outer side of the auxiliary lifting plates 21. At this time, by starting the second drive motor 23 to drive the auxiliary lifting plates 21 to move, the overall control length of the lifting assembly 7 can be adjusted, and the number of overall movable rollers relative to the lifting assembly 7 can be adjusted, thereby controlling the length and position of the middle working plane of the conveyor belt 6.

[0038] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
