Description

Technical Field

[0001] This invention relates to the field of conveying device technology, and in particular to a flat chain conveying mechanism. Background Technology

[0002] In modern industrial production, the efficiency of material conveying systems directly affects overall production capacity and cost control. Traditional conveying equipment, such as belt conveyors, while possessing continuous conveying capabilities, has significant shortcomings in terms of load-bearing capacity, impact resistance, and adaptability to complex processes.

[0003] Existing flat chain conveyors require support structures during rotational transport to prevent bending of the conveyor due to the weight of the conveyed material and the chain itself, which would affect the straight-line conveying. Traditional support methods primarily use plates and the chain for support, but this contact-based support has certain drawbacks. First, friction occurs when the chain slides between the chain and the support plate, leading to high energy consumption and noise. Second, flat chain conveyors require sprockets for transmission, and these sprockets need lubrication over long periods. Traditional lubrication requires stopping the device and manually applying lubricant, which is cumbersome, requires disassembly and reassembly, and is inconvenient. Therefore, a new flat chain conveyor mechanism is urgently needed to solve these problems. Summary of the Invention

[0012] Furthermore, a limiting groove is provided inside the chain plate, and the limiting slider fixed on the support rod slides inside the limiting groove.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1-14 As shown, the present invention has the following specific embodiments.

[0022] Example 1: A flat chain conveyor mechanism includes a conveyor frame 100, with grooved guide rails 102 fixedly connected to both sides inside the conveyor frame 100, and a conveying module is provided between the two grooved guide rails 102. The conveying module consists of several chain plates 300 and a conveying plate 400. The chain plates 300 are hinged to each other by a rotating shaft. The guide wheels 301 rotatably connected at both ends of the chain plates 300 are in rolling cooperation with two grooved guide rails 102. The transmission rod 302 fixed on the chain plate 300 is located on the same axis as the two guide wheels 301. Support rods 401 are fixedly connected to both ends of the bottom of the conveying plate 400. An iron block 402 is fixedly connected to one end of the support rod 401 that movably passes through the chain plate 300. The conveying module is equipped with a support module, which consists of an I-shaped steel frame 500 and bar electromagnets 700. Four magnetic levitation tracks 501 are fixedly connected to the I-shaped steel frame 500. The bar electromagnets 700 are four fixedly connected to the four magnetic levitation tracks 501 respectively. Each of the four bar electromagnets 700 is connected to a magnetic controller 701 through wires, and the magnetic controller 701 is fixedly connected to the conveyor frame 100. Lubrication components are provided at both ends of the bottom of the I-beam steel frame 500. The lubrication components are used to apply lubricating oil to the outer surface of the transmission rod 302. Also includes: The power mechanism is used to drive the conveying module to rotate and convey on the grooved guide rail 102.

[0023] Preferably, a limiting groove 303 is provided inside the chain plate 300, and the limiting slider 403 fixed on the support rod 401 slides inside the limiting groove 303.

[0024] Preferably, two rows of magnetic levitation tracks 501 are fixedly connected to the I-shaped steel frame 500. One end of the two rows of magnetic levitation tracks 501 is fixedly connected to the conveyor frame 100. The top of the magnetic levitation track 501 is provided with an opening. The support rod 401 is movably engaged with the magnetic levitation track 501 through the opening. The iron block 402 moves inside the magnetic levitation track 501.

[0025] In this embodiment, as Figure 1 , Figure 5 , Figure 6 and Figure 7 as well as Figures 10-14 As shown, firstly, the conveyor frame 100 serves as the supporting structure for the entire mechanism, and its two sides are fixedly connected with grooved guide rails 102, which provide the running track for the conveying module. The conveying module consists of multiple chain plates 300 and conveyor plates 400. The chain plates 300 are hinged together by rotating shafts to form a continuous conveying chain. Each chain plate 300 has guide wheels 301 rotatably connected to both ends. These guide wheels 301 roll in cooperation with the grooved guide rail 102 to ensure the smooth operation of the chain plate 300. A transmission rod 302 is also fixed on the chain plate 300, located on the same axis as the guide wheel 301, for transmitting power. Support rods 401 are fixedly connected to both ends of the bottom of the conveyor plate 400. The support rods 401 movably pass through the chain plate 300 and are fixedly connected to iron blocks 402 to stabilize the conveyor plate 400 on the chain plate 300. Then, the support module consists of an I-beam steel frame 500 and a bar electromagnet 700. Four magnetic levitation tracks 501 are fixedly connected to the I-beam steel frame 500. Each magnetic levitation track 501 is equipped with a bar electromagnet 700. The bar electromagnet 700 is connected to a magnetic controller 701 fixed on the conveyor frame 100 through wires. The levitation height of the conveyor plate 400 is controlled by adjusting the magnetic force, so as to achieve non-contact support and reduce friction and energy consumption. Finally, the power mechanism is provided to drive the rotating rod 101 and the sprocket 1011 to rotate, thereby driving the conveying module to circulate on the grooved guide rail 102, while the lubrication component provides lubricating oil to the surface of the transmission rod 302 of the conveying module to achieve automatic lubrication.

[0026] Example 2: The difference from Example 1 is that a driving structure for the conveying module is also disclosed: The power mechanism includes a servo motor 200 and two rotating rods 101. The rotating rods 101 are two rods that rotate at both ends of the conveyor frame 100. The sprockets 1011 fixed on the rotating rods 101 are located in the middle between the two conveyor frames 100. The left rotating rod 101 passes through the conveyor frame 100 and is fixedly connected to a first gear 1012. The servo motor 200 is fixed to the conveyor frame 100 through a dust cover 201. The second gear 202 fixed to the output shaft of the servo motor 200 meshes with the first gear 1012.

[0027] Preferably, the sprocket 1011 is engaged with the transmission rods 302 on a plurality of chain plates 300.

[0028] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, the power mechanism includes a servo motor 200 and two rotating rods 101. The two rotating rods 101 are rotatably connected to both ends of the conveyor frame 100. The sprockets 1011 fixed on them are meshed with the transmission rods 302 on the chain plate 300. By turning on the servo motor 200, the second gear 202 on the output shaft is driven to rotate. Since the first gear 1012 fixed on the left rotating rod 101 is meshed with the second gear 202, the servo motor 200 can drive the left rotating rod 101 to rotate on the conveyor frame 100. The rotating rod 101 drives the sprocket 101 to rotate, which in turn drives the conveying modules on the two sprockets 1011 to rotate and convey. The servo motor 200 is fixed to the conveyor frame 100 by a dust cover 201, which can protect the second gear 202 and the first gear 1012 inside from dust.

[0029] Example 3: The difference from Example 1 is that an automatic oiling structure for the lubrication component is also disclosed: The lubrication assembly includes an oil tank 600, with an oil outlet pipe 603 slidably connected to the bottom of the oil tank 600. A Y-shaped channel 6033 at one end of the oil outlet pipe 603 communicates with the oil tank 600 for conveying lubricating oil. A rubber plug 6032 is fixedly connected to the oil outlet pipe 603. The rubber plug 6032 is pressed by a spring 6041 to seal the outlet end of the oil tank 600. An inclined surface is provided at the outlet end of the oil outlet pipe 603. The transmission rod 302 slides with the oil outlet pipe 603 through the inclined surface.

[0030] Preferably, a fixed cover 602 is fixedly installed at the bottom of the oil tank 600, and the oil outlet pipe 603 is slidably connected in the fixed cover 602.

[0031] Preferably, a fixing plate 6031 is fixedly connected above the rubber stopper 6032, and two slide rods 604 are fixedly connected inside the oil tank 600. A spring 6041 is sleeved on the slide rod 604, and the fixing plate 6031 is movably connected to the slide rod 604, with the fixing plate 6031 located below the spring 6041.

[0032] Preferably, a sponge plug 6034 is embedded and fixed at the output end of the Y-type channel 6033.

[0033] Preferably, an oil inlet pipe 601 is connected through the top of the oil tank 600, and a valve is provided at one end of the oil inlet pipe 601 that passes through the I-shaped steel frame 500.

[0034] In this embodiment, as Figure 6 , Figure 8 and Figure 9 As shown, the lubrication assembly is located at both ends of the bottom of the I-beam steel frame 500, mainly including an oil tank 600 and an oil outlet pipe 603. The oil outlet pipe 603 is installed at the bottom of the oil tank 600 through a fixing cover 602. A Y-shaped channel 6033 at one end of the oil outlet pipe 603 is connected to the oil tank 600 for conveying lubricating oil. The other end of the oil outlet pipe 603 is provided with a fixing plate 6031 and a rubber plug 6032. A spring 6041 compresses the rubber plug 6032 to seal it with the outlet end of the oil tank 600.

[0035] When the transmission rod 302 slides to the outlet end of the oil outlet pipe 603, it squeezes the rubber plug 6032 to open the channel, allowing lubricating oil to be applied to the surface of the transmission rod 302, thus achieving automatic lubrication. Conversely, the spring 6041 squeezes the connected fixing plate 6031. Since the rubber plug 6032 and the fixing plate 6031 are fixed together on the oil outlet pipe 603, the rubber plug 6032 is squeezed at the outlet end of the oil tank 600 to seal it, preventing the lubricating oil from dripping automatically when the device is not running, thus saving lubricating oil.

[0036] Further explanation of this embodiment: the end of the oil outlet pipe 603 that is in contact with the transmission rod 302 is designed with an inclined surface, which facilitates the transmission rod 302 to push the oil outlet pipe 603 up and down when moving in a straight line, so that the oil outlet pipe 603 is connected to the inside of the oil tank 600 through the Y-shaped channel 6033 and opened, so that the lubricating oil in the oil tank 600 can flow out through the Y-shaped channel 6033. The sponge plug 6034 embedded at the outlet of the Y-shaped channel 6033 can reduce the flow rate of the lubricating oil and prevent the lubricating oil from flowing out too quickly and causing waste.

[0037] As further explained in this embodiment, the oil inlet pipe 601 provided on the oil tank 600 facilitates the addition of lubricating oil into the oil tank 600, and the valve provided on the oil inlet pipe 601 can control its opening and closing.

[0038] Working principle of the invention: Start the servo motor 200, which drives the rotating rod 101 and sprocket 1011 to rotate through gear transmission. The sprocket 1011 drives the transmission rod 302 on the chain plate 300 to move, so that the entire conveying module runs in a cycle on the grooved guide rail 102.

[0039] Meanwhile, the magnetic controller 701 adjusts the magnetic force of the bar electromagnet 700, causing the conveyor plate 400 to float on the magnetic levitation track 501, reducing friction and enabling non-contact support. This avoids the sliding friction in traditional contact support, significantly reducing frictional resistance and energy consumption during operation, while also reducing noise pollution.

[0040] During the conveying process, when the transmission rod 302 slides to the outlet end of the lubrication component oil outlet pipe 603, it is automatically coated with lubricating oil to ensure smooth operation. The lubrication component can automatically apply lubricating oil to the transmission rod 302 during the operation of the conveying module, without the need for manual operation during machine stop, which greatly improves production efficiency and reduces maintenance costs and time.

[0041] The servo motor 200 precisely controls the conveying speed, and the rolling cooperation of the grooved guide rail 102 and guide wheel 301 ensures the smooth operation of the conveying module and improves the reliability and stability of the entire material conveying system.

These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.
