Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, specifically a multi-layer stepping rotary device. Background Technology

[0002] Multi-layer stepping rotary devices are used in industrial automation for precise material conveying and circulation. They typically have a two-layer structure: the lower layer serves as a material waiting area, temporarily storing materials awaiting processing; the upper layer performs the transportation function, using a motor-driven synchronous belt, connecting rods, and other transmission components to move the materials according to a stepping rhythm, achieving material transfer and positioning between the two layers. Utilizing stepping rotary motion, it ensures the orderly flow of materials between the two layers, adapting to multi-station processing, inspection, and other scenarios, and improving the material turnover efficiency and connection accuracy of automated production lines.

[0003] However, existing multi-layer stepping rotary devices have significant drawbacks when transporting heavy materials such as steel pipes and square tubes: these devices typically lack clamping functionality during transport. Although the material adheres to the device due to gravity, it is still prone to falling out of the trough due to vibrations and tilting during operation, causing equipment jamming, component damage, and frequent shutdowns for cleaning. Simultaneously, the material is easily slipped and deviated during transport due to vibrations and acceleration / deceleration, leading to errors in subsequent workstation connections, such as misalignment in processing and assembly stages. This severely disrupts the production rhythm and significantly impacts conveying efficiency and production continuity. Therefore, structural optimization is urgently needed to compensate for the lack of clamping functionality and improve the stability of material transport. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a multi-layer stepping rotary device that has the advantage of stably clamping materials such as steel pipes and square tubes during transportation. This solves the problems in the prior art where the lack of clamping function leads to materials easily falling off, causing equipment jamming, component damage, frequent shutdowns for cleaning, and material deviation causing subsequent workstation docking errors, disrupting production rhythm, and affecting conveying efficiency and production continuity.

[0005] To achieve the aforementioned goal of stably clamping materials such as steel pipes and square tubes during transportation, this utility model provides the following technical solution: a multi-layer stepping rotary device, including an H-shaped support frame, with the main equipment frame fixedly connected to both sides of the H-shaped support frame, and material placement plates fixedly connected to both sides of the top of the H-shaped support frame. A conveying fixture trough is provided in the middle of the H-shaped support frame, and evenly distributed placement slots are provided on both sides of the top of the conveying fixture trough. On one side of the conveying fixture trough located in the middle of the placement slots, there are... There is a chute, and a T-shaped rod is provided at the middle position of each of the multiple placement slots. The bottom of the T-shaped rod passes through the conveying tooling trough and is slidably connected to the chute. The bottom of the T-shaped rod moves through and is rotatably connected to a rotating rod. The side of the rotating rod away from the T-shaped rod passes through the inner cavity of the conveying tooling trough and swings. One side of one of the placement slots passes through the conveying tooling trough and is slidably connected to an angled extrusion block. The side of the angled extrusion block away from the placement slot passes through and is rotatably connected to a rotating rod, and the outer wall of the rotating rod is fixedly connected to one end of the swing rod.

[0006] As a further embodiment of this utility model: a material waiting plate has evenly distributed waiting grooves on its top, a limiting groove is formed in the inner cavity of the material waiting plate near the waiting groove, a spring sheet is provided on one side of the inner cavity of the sliding groove, the limiting groove passes through the material waiting plate and is slidably connected to a limiting block on the side away from the spring sheet, and the limiting block and the spring sheet abut against each other.

[0007] As a further improvement of this utility model: a contact block is fixedly connected to the side of the limiting block away from the spring sheet, and the contact block slides in the middle position of the groove to be placed.

[0008] As a further improvement of this utility model: a rubber pad is fixedly connected to one of the angled extrusion blocks near the placement groove.

[0009] As a further embodiment of this utility model: a drive motor is installed on one side of the main frame of the device, and the output end of the drive motor passes through the main frame of the device and is fixedly connected to a synchronous pulley.

[0010] As a further embodiment of this utility model: the main frame of the equipment is rotatably connected to two synchronous wheels on one side above the synchronous wheel one. The outer walls of the synchronous wheel one and the synchronous wheel two are fitted with synchronous belts, and the synchronous wheel one and the synchronous wheel two are triangular in shape.

[0011] As a further embodiment of this utility model: two sets of L-shaped rotating rods are rotatably connected to both sides of the middle part of one side of the main frame of the equipment, and each set of L-shaped rotating rods consists of two rods. One side of each set of L-shaped rotating rods is fixedly connected to a second synchronous wheel. A first connecting block is rotatably connected to the side of each set of L-shaped rotating rods away from the H-shaped support frame and the second synchronous wheel. A second connecting block is fixedly connected to the top of each first connecting block. The side of the second connecting block away from the L-shaped rotating rod is fixedly connected to the conveying tooling trough.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, when transporting steel pipes and square tubes, the material's own weight presses down on the T-shaped rod, which in turn drives the first rotating rod, the swing rod, and the second rotating rod to move the angled extrusion block to slide and clamp the material in the placement groove. At the same time, the material's resistance pushes the contact block, causing the limiting block to compress the spring sheet and generate a reaction force to further fix the material. This achieves stable clamping of steel pipes and square tubes during transportation. Compared with existing technologies, this invention solves the problems of material deviation and falling caused by the lack of clamping function, reduces equipment jamming and component damage, eliminates the need for frequent shutdowns for cleaning, and improves conveying stability and production continuity.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 In this embodiment of the present invention, a multi-layer stepping rotary device includes an H-shaped support frame 1. A main equipment frame 2 is fixedly connected to both sides of the H-shaped support frame 1. Material placement plates 19 are fixedly connected to both sides of the top of the H-shaped support frame 1. A conveying fixture trough 10 is provided in the middle of the H-shaped support frame 1. Placement slots 11 are evenly distributed on both sides of the top of the conveying fixture trough 10. A sliding groove 12 is provided on one side of the conveying fixture trough 10 located in the middle of each placement slot 11. A T-shaped rod 13 is provided in the middle of each of the placement slots 11. The bottom of the T-shaped rod 13 penetrates the conveying fixture trough 10 and is slidably connected to the sliding groove 12. A rotating rod 14 is movably connected to the bottom of the T-shaped rod 13 and rotates through the inner cavity of the conveying fixture trough 10 on the side away from the T-shaped rod 13. One side of each placement slot 11 penetrates the conveying fixture trough 10. An angled extrusion block 16 is slidably connected to the T-shaped rod 13. The side of the angled extrusion block 16 away from the placement groove 11 is connected to a rotating rod 17. The outer wall of the rotating rod 17 is fixedly connected to one end of the swing rod 15. When transporting steel pipes and square tubes, the material enters the placement groove 11 and presses down the T-shaped rod 13 by its own weight. The T-shaped rod 13 slides down in the slide groove 12. Its bottom drives the rotating rod 14 to move, causing the swing rod 15 connected to the outer wall of the rotating rod 14 to swing down. During the swinging process, the rotating rod 15 drives the angled extrusion block 16 to slide in the placement groove 11 through the rotating rod 17 fixedly connected to it, and squeezes and clamps the steel pipes and square tubes on the T-shaped rod 13. A rubber pad 18 is fixedly connected to the side of the angled extrusion block 16 close to the placement groove 11. At the same time, the rubber pad 18 on the side of the angled extrusion block 16 contacts the material first to avoid damage to the material during clamping.

[0022] A material placement plate 19 has evenly distributed placement slots 20 on its top. A limiting groove 21 is formed in the inner cavity of the material placement plate 19 near the placement slots 20. A spring sheet 22 is provided on one side of the inner cavity of the sliding groove 12. The limiting groove 21, away from the spring sheet 22, passes through the material placement plate 19 and is slidably connected to a limiting block 23, which abuts against the spring sheet 22. An abutting block 24 is fixedly connected to the side of the limiting block 23 away from the spring sheet 22. The middle position of the trough 20 slides. When the steel pipe and square tube are transported to the material waiting plate 19 by the conveying tool trough 10, the steel pipe and square tube will first come into contact with the abutting block 24 in the waiting trough 20. Under the pushing force of the material, the abutting block 24 drives the limiting block 23 to slide in the limiting groove 21. The limiting block 23 squeezes the spring plate 22. The reaction force of the spring plate 22 is transmitted to the material in the waiting trough 20 through the limiting block 23 and the abutting block 24, so as to further squeeze and fix the material.

[0023] A drive motor 3 is installed on one side of the main frame 2 of the equipment. The output end of the drive motor 3 passes through the main frame 2 of the equipment and is fixedly connected to a synchronous pulley 4. Two synchronous pulleys 5 are rotatably connected above the synchronous pulley 4 on one side of the main frame 2. Synchronous belts 6 are fitted on the outer walls of the synchronous pulleys 4 and 5, and the synchronous pulleys 4 and 5 are triangular in shape. Two sets of L-shaped rotating rods 7 are rotatably connected to both sides of the middle of one side of the main frame 2 of the equipment. Each set of L-shaped rotating rods 7 consists of two rods. One side of each set of L-shaped rotating rods 7 is fixedly connected to the synchronous pulley 5. The side of each set of L-shaped rotating rods 7 away from the H-shaped support frame 1 and the synchronous pulley 5 is... Both are rotatably connected to a connecting block 1 8, and the top of each connecting block 1 8 is fixedly connected to a connecting block 2 9. The side of connecting block 2 9 away from the L-shaped rotating rod 7 is fixedly connected to the conveying tooling trough 10. After the drive motor 3 starts, its output end drives the synchronous wheel 1 4 to rotate. The synchronous wheel 1 4 drives the two synchronous wheels 2 5 to rotate synchronously through the synchronous belt 6. Since the synchronous wheel 1 4 and the synchronous wheel 2 5 are triangular, the movement of the synchronous belt 6 causes the two sets of L-shaped rotating rods 7 fixedly connected to it to swing around the connection point of the main frame 2 of the equipment. The side of the two sets of L-shaped rotating rods 7 away from the synchronous wheel 2 5 drives the conveying tooling trough 10 to achieve stepping rotational motion through the connecting block 1 8 and the connecting block 2 9.

[0024] The working principle of this utility model is as follows: After the drive motor 3 starts, its output end drives the synchronous wheel 4 to rotate. The synchronous wheel 4 drives the two synchronous wheels 5 to rotate synchronously through the synchronous belt 6. Since the synchronous wheel 4 and the synchronous wheel 5 are triangular, the movement of the synchronous belt 6 causes the two sets of L-shaped rotating rods 7 fixedly connected to it to swing around the connection point of the main frame 2 of the equipment. The side of the two sets of L-shaped rotating rods 7 away from the synchronous wheel 5 drives the conveying tooling trough 10 to achieve stepping rotation through the connecting block 8 and the connecting block 9.

[0025] When transporting steel pipes and square tubes, the material enters the placement trough 11 and presses down the T-shaped rod 13 by its own weight. The T-shaped rod 13 slides down in the slide trough 12, and its bottom drives the rotating rod 14 to move, causing the swing rod 15 connected to the outer wall of the rotating rod 14 to swing down. During the swinging process, the swing rod 15 drives the angled extrusion block 16 to slide in the placement trough 11 through the rotating rod 2 17 fixedly connected to it, and squeezes and clamps the steel pipes and square tubes on the T-shaped rod 13. At the same time, the rubber pad 18 on one side of the angled extrusion block 16 contacts the material first to avoid damage to the material during clamping.

[0026] When the steel pipe and square tube are transported to the material waiting plate 19 by the conveying tool trough 10, the steel pipe and square tube will first come into contact with the abutting block 24 in the waiting trough 20. Under the pushing force of the material, the abutting block 24 drives the limiting block 23 to slide in the limiting groove 21. The limiting block 23 squeezes the spring sheet 22. The reaction force of the spring sheet 22 is transmitted to the material in the waiting trough 20 through the limiting block 23 and the abutting block 24, so as to further squeeze and fix the material.

[0027] When the material waiting plate 19 continues to rotate and transport the next material, and the current steel pipe and square tube are separated from the material waiting plate 19, the material will come into contact with the angled extrusion block 16 at the angle, generating a force that resets the angled extrusion block 16. Under the action of this force, the angled extrusion block 16 slides into the placement groove 11, and drives the swing rod 15 to swing upward through the rotating rod 17. The swing rod 15 then drives the T-shaped rod 13 to slide upward and reset in the slide groove 12 through the rotating rod 14, completing the reset of the entire clamping mechanism and preparing for the next material transport.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
