Abstract
Description
Technical Field
[0001] This application relates to the technical field of escalator manufacturing, and in particular to an elevator drive chain sprocket feeding mechanism. Background Technology
[0002] In the manufacturing process of escalators, the escalator drive chain is one of the core transmission components. The escalator drive chain is composed of multiple links spliced together, and each link usually contains two sprockets. As a key component of the escalator drive chain, the transportation of the sprockets during the assembly process is particularly important.
[0003] Traditional escalator drive chain assembly typically involves transporting sprockets to a designated location via a conveyor belt for assembly. Workers then manually insert the sprockets into the two ends of the chain link pins, followed by press-fitting using a press machine. In practice, sprockets tend to stack on the conveyor belt during transport, requiring manual removal of excess stacked sprockets. This results in high labor intensity and low sprocket transport efficiency. Summary of the Invention
[0004] In order to improve the transportation efficiency of sprockets, this application provides an elevator transmission chain sprocket feeding mechanism, which has the effect of improving the transportation efficiency of sprockets.
[0005] The technical solution provided in this application is as follows:
[0006] An elevator drive chain sprocket feeding mechanism includes a material box equipped with multiple sprockets. A frame is provided on the side wall of the material box. A feeding conveyor belt and a discharging conveyor belt for transporting sprockets are provided on the frame. The feeding conveyor belt is inclined between the discharging conveyor belt and the material box. The discharging conveyor belt is arranged along the length of the frame. The feeding end of the feeding conveyor belt is located inside the material box. A slide rail channel connecting the feeding conveyor belt and the discharging conveyor belt is provided on the feeding conveyor belt. A guide plate is provided on the discharging conveyor belt. The height of the guide plate is greater than the height of the sprockets. A receiving plate is provided on the side of the discharging conveyor belt near the material box. The discharging end of the receiving plate is located inside the material box.
[0007] By adopting the above technical solution, when work begins, the feeding conveyor belt is started, transporting multiple sprockets from the material box to the slide rail channel. The sprockets then slide down the slide rail channel to the unloading conveyor belt. After the sprockets on the feeding conveyor belt fall off, the other sprockets continue to move forward with the feeding conveyor belt. Because multiple sprockets may become tightly connected when sliding down the slide rail channel to the unloading conveyor belt, multiple sprockets may stack on the unloading conveyor belt.
[0008] When the height of multiple sprockets stacked is greater than the height of the guide plate, the guide plate can block the stacked sprockets. The sprockets blocked by the guide plate will fall into the receiving plate through the short plate, and then slide down into the material box along the receiving plate. This can reduce the stacking of sprockets on the unloading conveyor belt, so that the sprockets on the unloading conveyor belt can remain in an orderly state, reduce manual cleaning time, and effectively improve the transportation efficiency of sprockets.
[0009] Optionally, side plates are provided on both sides of the feeding conveyor belt, and both side plates are arranged along the length direction of the feeding conveyor belt.
[0010] By adopting the above technical solution, the two side plates can effectively reduce the sprocket falling off both sides of the feeding conveyor belt and improve the stability of the sprocket feeding process.
[0011] Optionally, the feeding conveyor belt is provided with multiple partitions at intervals, the multiple partitions are located between two side plates, and the height of the multiple partitions is greater than the thickness of the sprocket.
[0012] By adopting the above technical solution, multiple partitions can separate multiple sprockets into independent spaces, reducing the phenomenon of multiple sprockets stacking on the feeding conveyor belt. The partitions can abut against the sprockets, reducing the possibility of sprockets flowing back into the material box on the feeding conveyor belt, effectively improving the stability of the sprockets on the feeding conveyor belt.
[0013] Optionally, a cover plate is provided on the side of the two partitions away from the feeding conveyor belt, and the cover plate is arranged along the length direction of the feeding conveyor belt.
[0014] By adopting the above technical solution, the shield can protect the sprockets inside the feeding conveyor belt and effectively prevent foreign objects from entering the feeding conveyor belt, which is beneficial for workers to check the feeding status of the sprockets inside the feeding conveyor belt.
[0015] Optionally, limit plates are provided on both sides of the feeding conveyor belt, and a notch is provided on the limit plate on the side of the feeding conveyor belt near the material box, the length of the notch being less than the width of the receiving plate.
[0016] By adopting the above technical solution, the notch and the receiving plate cooperate to form a return channel for the blocked sprockets, so that the excess sprockets can accurately slide through the notch to the receiving plate, reducing the phenomenon of sprockets accumulating on the unloading conveyor belt.
[0017] Optionally, an inclined guide plate is provided on the limiting plate on the side of the feeding conveyor belt near the material box, and the inclined guide plate is located at the bottom of the slide rail channel.
[0018] By adopting the above technical solution, the inclined guide plate can provide guidance for the sprocket falling along the slide rail channel, so that the sprocket can slide smoothly from the inclined surface of the inclined guide plate to the material conveyor belt, reducing the sprocket falling off the side wall of the material conveyor belt and effectively improving the stability of sprocket feeding.
[0019] Optionally, the width of the feeding conveyor belt is adapted to the size of a single sprocket.
[0020] By adopting the above technical solution, the width of the feeding conveyor belt can only accommodate a single vertical sprocket, so that multiple vertical sprockets are arranged sequentially on the feeding conveyor belt, which facilitates the subsequent assembly work of the workers.
[0021] Optionally, a guide cloth is provided on the receiving plate.
[0022] By adopting the above technical solution, when the sprocket slides from the feeding conveyor belt to the receiving plate, the guide cloth can play a buffering role and reduce the friction between the sprocket and the receiving plate, effectively ensuring the appearance quality of the sprocket and extending its service life.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. When the sprockets slide along the slide rail channel onto the feeding conveyor belt and stack up, the guide plate can guide the stacked sprockets through the notch and slide along the receiving plate into the material box. This can reduce the stacking of sprockets on the feeding conveyor belt, keep the remaining sprockets on the feeding conveyor belt in an orderly state, reduce manual cleaning time, facilitate the next assembly work, and effectively improve the transportation efficiency of the sprockets.
[0025] 2. The partitions on the feeding conveyor belt can separate multiple sprockets into independent spaces, and the top of the partitions can abut against the sprockets, reducing the possibility of sprockets flowing back into the material box and effectively improving the stability of sprocket feeding;
[0026] 3. The short plate has a notch at the position corresponding to the receiving plate, and the stacked sprockets can slide down to the receiving plate through the notch, further reducing the phenomenon of sprockets accumulating on the unloading conveyor belt. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.
[0031] This application discloses an elevator drive chain sprocket feeding mechanism, referring to... Figure 1 and Figure 2 The system includes a frame 2, with a material box 1 equipped with sprockets placed on one side of the frame 2. A feeding conveyor belt 3 and a discharging conveyor belt 4 are mounted on the frame 2. The feeding conveyor belt 3 is inclined and fixed between the material box 1 and the discharging conveyor belt 4, while the discharging conveyor belt 4 is fixed to the frame 2 along its length. A slide rail channel 5 is integrally formed at the discharge end of the feeding conveyor belt 3. The height of the slide rail channel 5 is greater than the height of the discharging conveyor belt 4, and the slide rail channel 5 connects the feeding conveyor belt 3 and the discharging conveyor belt 4. A guide plate 6 is threaded onto the discharging conveyor belt 4, with its free end facing the material box 1. A receiving plate 7 is fixed to the side of the discharging conveyor belt 4 closest to the material box 1, with the end of the receiving plate 7 away from the discharging conveyor belt 4 located inside the material box 1.
[0032] The feeding conveyor belt 3 transports the horizontally positioned sprockets from the material box 1 to the slide rail channel 5. Under their own gravity, the sprockets slide down the slide rail channel 5 and become vertical on the unloading conveyor belt 4. When the stacked height of multiple sprockets on the unloading conveyor belt 4 exceeds the height of the guide plate 6, the guide plate 6 can block the stacked sprockets, causing them to slide down along the receiving plate 7 into the material box 1. This reduces the stacking of sprockets on the feeding conveyor belt 3, reduces manual cleaning time, and helps improve the transportation efficiency of the sprockets.
[0033] Side plates 8 are bolted to both sides of the feeding conveyor belt 3. Both side plates 8 are positioned along the length of the feeding conveyor belt 3, reducing the likelihood of sprockets falling off the sides of the feeding conveyor belt 3. Multiple partitions 9 are vertically fixed at intervals on the feeding conveyor belt 3, located between the two side plates 8. The partitions 9 divide the feeding conveyor belt 3 into multiple independent spaces, reducing the stacking of multiple sprockets on the feeding conveyor belt 3. Furthermore, the partitions 9 can abut against multiple sprockets, reducing the possibility of multiple sprockets flowing back into the material box 1, effectively improving the stability of the sprocket feeding process.
[0034] A cover plate 10 is bolted to the side of the two side plates 8 away from the feeding conveyor belt 3. The cover plate 10 is a transparent plate, which makes it easy to see the condition of the sprocket inside the feeding conveyor belt 3. The feeding conveyor belt 3, the cover plate 10 and the two side plates 8 form a three-dimensional protective structure, which effectively reduces the entry of foreign objects into the feeding conveyor belt 3 and improves the stability of the sprocket in the feeding conveyor belt 3.
[0035] Limiting plates 11 are fixed on both sides of the feeding conveyor belt 4. A notch 12 is provided on the limiting plate 11 near the material box 1. The guide plate 6 can guide the stacked sprockets to slide down into the material box 1 through the notch 12 along the receiving plate 7.
[0036] An inclined guide plate 13 is integrally formed on the limiting plate 11 on the side of the feeding conveyor belt 4 near the material box 1. The inclined guide plate 13 and the limiting plate 11 are flared on the feeding conveyor belt 4. Multiple support rods 15 are fixed at intervals on the side of the feeding conveyor belt 4 near the receiving plate 7. The multiple support rods 15 are vertically fixed on the frame 2. The ends of the multiple support rods 15 away from the frame 2 are welded and fixed to the bottom of the inclined guide plate 13. The free end of the inclined guide plate 13 is located at the bottom of the slide rail channel 5, which can effectively reduce the sprocket falling off the side wall of the feeding conveyor belt 4 and improve the stability of the sprocket feeding.
[0037] The width of the feeding conveyor belt 4 is greater than the thickness of the sprocket, and the width of the feeding conveyor belt 4 is less than the outer diameter of the sprocket. The horizontal sprocket can slide down along the inclined guide plate 13 to the feeding conveyor belt 4 so that it is in a vertical state, which is convenient for the workers to carry out subsequent assembly work.
[0038] The guide cloth 14 and the receiving plate 7 are detachably connected, and the guide cloth 14 is glued to the receiving plate 7. When the sprocket slides from the unloading conveyor belt 4 into the receiving plate 7 under the action of the guide plate 6, the guide cloth 14 can reduce the friction between the sprocket and the receiving plate 7, effectively ensuring the appearance quality of the sprocket and extending the service life of the sprocket.
[0039] The implementation principle of the elevator drive chain sprocket feeding mechanism disclosed in this application embodiment is as follows: First, the feeding conveyor belt 3 is started, and the feeding conveyor belt 3 transports the horizontally positioned sprocket from the material box 1 to the slide rail channel 5. At this time, under the action of its own gravity, the sprocket falls into the unloading conveyor belt 4 along the slide rail channel 5 and is in a vertical position, which is convenient for workers to assemble. When multiple sprockets are stacked on the unloading conveyor belt 4, and the height of the stacked sprockets is greater than the height of the guide plate 6, the guide plate 6 can block the stacked sprockets, so that the stacked sprockets flow back to the material box 1 through the notch 12 along the receiving plate 7, reducing the phenomenon of excess sprockets stacking on the conveyor belt, reducing manual cleaning time, and improving the transportation efficiency of the sprockets.
[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
