Description

Technical Field

[0001] This application relates to the field of rubber and plastic product processing technology, specifically to an elevator load-bearing guide wheel production device. Background Technology

[0002] The load-bearing guide roller is an important component of the elevator operating system. It is usually installed on the car frame and is in direct contact with the guide rail. Its main function is to ensure that the car moves accurately up and down along the guide rail and to suppress or weaken the transmission of vibrations from the guide rail to the car frame and car, thereby ensuring the stability, comfort and safety of the elevator operation. As a key part of the elevator, the performance of the load-bearing guide roller directly affects the elevator's operating efficiency and the passenger's riding experience.

[0003] However, the production of existing elevator load-bearing guide rollers involves multiple processes, such as material preparation, molding, and bonding. If the connection between these processes is not tight, or if there are long waiting times, the production process will be disjointed, which will affect the overall production efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides an elevator load-bearing guide wheel production device, which has advantages such as improved production efficiency. It solves the problem that the production of existing elevator load-bearing guide wheels involves multiple processes, such as material preparation, molding, and bonding. If the connection between these processes is not tight, or if there are long waiting times, the production process will be discontinuous, thus affecting the overall production efficiency.

[0005] To achieve the above objectives, this application provides the following technical solution: an elevator load-bearing guide wheel production device, comprising a workbench and multiple telescopic arms, a first support arm fixedly connected to one side of the upper end of the workbench, a motor fixedly connected to one side of the first support arm, a rotating disk fixedly connected to the output end of the motor through the first support arm, multiple second support arms fixedly connected to the outside of the rotating disk, each of the multiple second support arms having a sliding groove inside, and each of the multiple second support arms having four positioning holes arranged in a rectangular array inside.

[0006] Each of the multiple telescopic arms has four positioning pins and springs fixedly connected to its upper end in a rectangular array. A sliding plate is fixedly connected to the upper end of each of the multiple telescopic arms. A tire-loading shaft is fixedly connected to one side of each of the multiple telescopic arms. An electric push rod is fixedly connected to one side of the inner side of each of the multiple telescopic arms. A support seat is fixedly connected to the telescopic end of each of the multiple electric push rods. Three first rotating seats arranged in a circular array are fixedly connected to the outer wall of each of the multiple support seats. A connecting rod is rotatably connected inside each of the multiple first rotating seats. A second rotating seat is rotatably connected to the end of each connecting rod away from the first rotating seat. Three movable plates arranged in a circular array are slidably connected to the inner wall of each of the multiple tire-loading shafts.

[0007] Through the above scheme, the device achieves automatic extension and retraction of the telescopic arms by using multiple telescopic arms and cooperating with the positioning pins and springs on the telescopic arms and the sliding grooves on the second support arms. The position of the telescopic arms can be adaptively adjusted according to the load-bearing guide wheels of different diameters. The telescopic end of the electric push rod is connected to the support base. Three first rotating seats arranged in a circular array are fixedly connected to the outer wall of the support base. A connecting rod is rotatably connected inside the first rotating seat, and the other end of the connecting rod is rotatably connected to a second rotating seat. The second rotating seat is connected to a movable plate inside the outer wall of the tire mounting shaft. This design allows the position of the movable plate inside the tire mounting shaft to be adjusted by the extension and retraction of the electric push rod. The expansion of the movable plate fixes the load-bearing guide wheel to be processed. The motor drives the rotating disk to rotate, which can drive multiple second support arms and telescopic arms to rotate simultaneously, processing the load-bearing guide wheels to be processed sequentially, making the production line more continuous and improving production efficiency.

[0008] Furthermore, two side plates arranged in a mirror image are fixedly connected to the upper end of the workbench, and a conveying device is fixedly connected between the two side plates.

[0009] Through the above scheme, the conveying device can adjust its speed and direction according to production needs to transport raw materials to designated locations.

[0010] Furthermore, a support plate is fixedly connected between the two side plates, and a plurality of through holes arranged in a straight line are opened through the support plate, and heating tubes are fixedly connected inside the plurality of through holes.

[0011] With the above solution, since the heating tubes are evenly distributed in the through holes of the support plate, it is possible to ensure that the passing film is heated evenly, so that the material is not easily cooled down, and the required temperature and state are ensured to maintain the surface adhesion, so that the film is firmly attached to the load-bearing guide wheel.

[0012] Furthermore, each of the two side plates is fixedly connected to one side with a correction plate, and each of the two correction plates is fixedly connected to the side plate with three support rods arranged in a linear array. A support frame is fixedly connected to the upper end of the two correction plates, and a hydraulic rod is fixedly connected inside the support frame. A cutter is fixedly connected to the telescopic end of the hydraulic rod.

[0013] The above solution helps to accurately adjust the position of the film during the transmission process. The support rod strengthens the connection between the correction plate and the side plate. The hydraulically driven cutter can accurately cut the film and reduce cutting errors caused by manual cutting.

[0014] Furthermore, a composite extruder is provided on one side of the upper end of the conveying device.

[0015] The above scheme uses a composite extruder to extrude the coating material into the desired film.

[0016] Furthermore, multiple sliding plates are slidably disposed inside the sliding groove, multiple positioning pins are slidably disposed inside the positioning hole, and multiple springs are fixedly connected to the second support arm in groups of four at the end away from the telescopic arm.

[0017] According to the above scheme, a composite extruder is a device that mixes two or more materials and then extrudes them. By extruding the melted material, it is pressed into a mold, and the mold shape is used to shape the desired product. In the production process of elevator load-bearing guide wheels, the composite extruder can heat, melt, and mix the coating raw materials, and then extrude them into the desired film shape through a mold.

[0018] Furthermore, the support plate is fixedly installed inside the conveying device.

[0019] By directly fixing the support plate inside the conveying device, the support plate acts as a fixed component inside the conveying device, providing support and preventing the conveying device from deforming after being squeezed by the fixed guide rollers.

[0020] Furthermore, the ends of the plurality of second rotating seats away from the connecting rod are all fixedly connected to the movable plate.

[0021] With the above scheme, the connecting rods enable the electric push rod to move, causing the moving plate to move outward inside the tire mounting shaft, thereby fixing the load-bearing guide wheel to the outer wall of the tire mounting shaft.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This elevator guide wheel production device uses a motor-driven rotating disc to simultaneously rotate multiple second support arms and telescopic arms, achieving automated production line operation. The telescopic arms are designed to adaptively adjust their position to accommodate guide wheels of different diameters, enhancing production flexibility. The electric push rod, through a connecting rod and moving plate design, can precisely adjust the position of the moving plate inside the mounting shaft. The expansion of the moving plate secures the guide wheel to be processed. Through-holes and fixed heating pipes inside the support plate uniformly heat the passing film, helping to maintain the required temperature and condition of the material. This ensures a firm fit between the film and the load-bearing guide rollers, thereby improving product quality. The alignment plate helps to accurately adjust the position of the film during the conveying process, while the hydraulically driven cutter enables accurate cutting of the film, reducing errors caused by manual cutting and improving production precision. The composite extruder can extrude the coating material into the required film shape. By directly fixing the support plate inside the conveying device, the support plate, as a fixed component inside the conveying device, provides support, so that the conveying device will not deform after being squeezed by the fixed guide rollers, allowing the film to smoothly wrap around the outer wall of the load-bearing guide rollers.

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] Please see Figure 1 , Figure 2 and Figure 3 An elevator load-bearing guide wheel production device in this embodiment includes a workbench 1 and multiple telescopic arms 8. A first support arm 2 is fixedly connected to one side of the upper end of the workbench 1. The first support wall is used to support the rotating device. A motor 3 is fixedly connected to one side of the first support arm 2. The motor 3 is used to drive multiple processing devices to rotate simultaneously. A rotating disk 4 is fixedly connected to the output end of the motor 3 through the first support arm 2. Multiple second support arms 5 are fixedly connected to the outside of the rotating disk 4. By rotating the rotating disk 4, multiple second support walls can be rotated simultaneously. Each of the multiple second support arms 5 has a sliding groove 6 inside and four positioning holes 7 arranged in a rectangular array inside.

[0034] Please see Figure 2 and Figure 3Each of the multiple telescopic arms 8 has four positioning posts 9 arranged in a rectangular array and springs 10 fixedly connected to its upper end. A sliding plate 11 is fixedly connected to the upper end of each of the multiple telescopic arms 8. A tire mounting shaft 12 is fixedly connected to one side of each of the multiple telescopic arms 8. An electric push rod 13 is fixedly connected to one side of the inside of each of the multiple telescopic arms 8. A support base 14 is fixedly connected to the telescopic end of each of the multiple electric push rods 13. Three first rotating seats 15 arranged in a circular array are fixedly connected to the outer wall of each of the multiple support seats 14. A connecting rod 16 is rotatably connected inside each of the multiple first rotating seats 15. A second rotating seat 17 is rotatably connected to the end of each connecting rod 16 away from the first rotating seat 15. Three movable plates 18 arranged in a circular array are slidably connected to the inner wall of the tire mounting shaft 12. The telescopic end of the electric push rod 13 is connected to the support base 14. Three first rotating seats 15 arranged in a circular array are fixedly connected to the outer wall of the support base 14. A connecting rod 16 is rotatably connected inside the first rotating seat 15. The other end of the connecting rod 16 is rotatably connected to a second rotating seat 17. The second rotating seat 17 is connected to the movable plates 18 inside the outer wall of the tire mounting shaft 12. This design allows the position of the movable plates 18 inside the tire mounting shaft 12 to be adjusted by the telescopic movement of the electric push rod 13. The expansion of the movable plates 18 fixes the load-bearing guide wheel to be processed.

[0035] Please see Figure 4 , Figure 5 and Figure 6 Two mirror-shaped side plates 19 are fixedly connected to the upper end of the workbench 1. A conveyor device 20 is fixedly connected between the two side plates 19. The conveyor device 20 can be adjusted in speed and direction according to production needs to transport raw materials to a designated position. A support plate 23 is fixedly connected between the two side plates 19. Multiple through holes 24 are arranged in a straight line through the support plate 23. Heating tubes 25 are fixedly connected inside each of the through holes 24. Since the heating tubes 25 are evenly distributed in the through holes 24 of the support plate 23, they can ensure that the passing film is heated evenly, so that the material does not cool down easily. This ensures the required temperature and state to maintain the surface adhesion and make the film firmly adhere to the load-bearing guide roller. Both side plates 19 have... A correction plate 21 is fixedly connected. Three support rods 22 arranged in a straight array are fixedly connected between each correction plate 21 and the side plate 19. A support frame 26 is fixedly connected to the upper end of each correction plate 21. A hydraulic rod 27 is fixedly connected inside the support frame 26. A cutter 28 is fixedly connected to the telescopic end of the hydraulic rod 27. The design of the correction plate 21 helps to accurately adjust the position of the film during the conveying process. The support rods 22 are used to strengthen the connection between the correction plate 21 and the side plate 19. The cutter 28 driven by the hydraulic rod 27 can accurately cut the film and reduce the cutting error caused by manual cutting. A composite extruder 29 is set on one side of the upper end of the conveying device 20. The composite extruder 29 is used to extrude the coating material into the required film.

[0036] Please see Figure 1 , Figure 3 and Figure 5 Multiple sliding plates 11 are slidably disposed inside the slide groove 6, multiple positioning pins 9 are slidably disposed inside the positioning holes 7, and multiple springs 10 are fixedly connected to the second support arm 5 in groups of four at the end away from the telescopic arm 8. The composite extruder 29 is a device for extruding a mixture of two or more materials. By extruding the melted material, it is pressed into a mold, and the desired product is shaped by the mold. In the production process of elevator load-bearing guide wheels, the composite extruder 29 can heat, melt, and mix the coating raw materials, and then extrude them into the desired film shape through the mold. The support plate 23 is fixedly disposed. Inside the conveying device 20, the support plate 23 is directly fixed inside the conveying device 20. The support plate 23 serves as a fixed component inside the conveying device 20, providing support so that the conveying device 20 will not deform after being squeezed by the fixed guide wheel. The ends of the multiple second rotating seats 17 away from the connecting rod 16 are all fixedly connected to the moving plate 18. Through the connection of the connecting rod 16, when the electric push rod 13 moves, the moving plate 18 is driven to move through the connecting rod 16, so that the moving plate 18 moves outward inside the tire mounting shaft 12 to fix the load-bearing guide wheel to the outer wall of the tire mounting shaft 12.

[0037] In this embodiment, the elevator load-bearing guide wheel production device uses a motor 3 to drive a rotating disk 4 to rotate, which in turn drives multiple second support arms 5 and telescopic arms 8 to rotate simultaneously, thus achieving automated production line operation. Furthermore, the telescopic arms 8 are designed to adaptively adjust their position according to load-bearing guide wheels of different diameters, enhancing production flexibility. The electric push rod 13, through the design of the connecting rod 16 and the moving plate 18, can precisely adjust the position of the moving plate 18 inside the mounting shaft 12. The expansion of the moving plate 18 fixes the load-bearing guide wheel to be processed. The through-hole 24 and the fixedly connected heating pipe 25 inside the support plate 23 uniformly heat the passing film, helping to maintain the required material properties. The temperature and condition of the film ensure a firm fit between the film and the load-bearing guide roller, thereby improving product quality. The alignment plate 21 helps to accurately adjust the position of the film during the conveying process, while the cutter 28 driven by the hydraulic rod 27 can accurately cut the film, reducing errors caused by manual cutting and improving production precision. The composite extruder 29 can extrude the coating material into the required film shape. By directly fixing the support plate 23 inside the conveying device 20, the support plate 23, as a fixed component inside the conveying device 20, provides support, so that the conveying device 20 will not deform after being squeezed by the fixed guide roller, allowing the film to be smoothly wrapped around the outer wall of the load-bearing guide roller.

[0038] It should be noted that the upper part of the support base 14 is triangular, and each face of the triangle is fixedly connected to the first rotating base 15.

[0039] The working principle of the above embodiments is as follows:

[0040] First, raw materials are added to the composite extruder 29. The coating material is heated, melted, and mixed, and then extruded into the required film shape through a die. The conveying device 20 adjusts the speed and direction according to production needs and transports the extruded film to the designated position. During the conveying process, the heating tube 25 inside the support plate 23 heats the passing film evenly to maintain the required temperature and state of the material, ensuring a firm fit between the film and the load-bearing guide wheel. The position is adjusted by the straightening plate 21 to ensure alignment between the film and the load-bearing guide wheel. When the film reaches the designated position, the cutter 28 driven by the hydraulic rod 27 accurately cuts the film to meet the coating requirements of the load-bearing guide wheel. Then, the load-bearing guide wheel is fitted onto the outer wall of the mounting shaft 12. Through the extension and retraction of the electric push rod 13, the moving plate 18 is moved outward inside the mounting shaft 12 via the connecting rod 16. The motor 3 drives the rotating disk 4 to rotate, which in turn drives multiple second support arms 5 and telescopic arms 8 to rotate simultaneously, moving the load-bearing guide wheel to the upper end of the film. As the load-bearing guide wheel moves, the film comes into contact with and adheres to the outside of the load-bearing guide wheel through the support of the support plate 23 and the compression of the spring 10. As the conveying device 20 continues to move, it drives the load-bearing guide wheel to rotate, making the film completely adhere to the outer wall of the load-bearing guide wheel. Then the motor 3 starts again, moving the completed load-bearing guide wheel out of the processing position. The electric push rod 13 is retracted, causing the moving plate 18 to move towards the center of the load-bearing shaft 12, releasing the load-bearing guide wheel so that the operator can easily remove it. Then another load-bearing guide wheel on the outer wall of the load-bearing shaft 12 comes into contact with the subsequent film for processing, and the above actions are repeated.
