Abstract
Description
Technical Field
[0001] This utility model belongs to the field of noise reduction technology at the connection of conveyor lines, and specifically relates to a noise reduction structure applied to the connection of workpiece conveyor lines. Background Technology
[0002] As a core conveying equipment in the field of industrial automation, the main function of the conveyor line is to complete the task of conveying workpieces. Under the production instructions issued by the production management system, the workpieces are transported from one position to another through the conveyor line, thereby realizing the continuous transmission of workpieces. The conveyor line can replace traditional manual handling and optimize the efficiency of cargo flow. Based on the preset conveyor line track, the conveyor line can avoid problems such as cargo damage and sorting errors that may be caused by manual handling, and enhance the standardization and accuracy of operations.
[0003] Normally, workpieces are transported using a single conveyor line. However, in practical applications, to save costs, two conveyor lines may share a single conveyor line. For example, in the normalizing process, two normalizing lines may share a single annealing line. The workpieces processed in the normalizing process are mostly steel parts. At the junction of the two conveyor lines, the workpieces falling can generate a lot of noise. Excessive noise can affect the health of workers and reduce work efficiency. Summary of the Invention
[0004] The purpose of this invention is to provide a noise reduction structure for use at the connection of a workpiece conveyor line, in order to solve the problems mentioned in the background art.
[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows: A noise reduction structure applied at the junction of a workpiece conveyor line includes a lifting mechanism installed at the front of the conveyor line for connecting different conveyor lines. The lifting mechanism includes a rotating plate with a groove at its bottom. A connecting rod is rotatably connected to the rear of the rotating plate. A bracket is installed at the bottom of the rotating plate, and a telescopic mechanism is installed at the bottom of the bracket. The telescopic mechanism includes a cylinder comprising an upper cavity, a lower cavity, and an outer cavity. A first one-way valve is installed on the right side of the bottom of the lower cavity, and a first damping valve is installed on the left side of the bottom of the lower cavity. A telescopic rod is installed inside the cylinder. A second one-way valve is installed on the left side of the bottom of the telescopic rod, and a second damping valve is installed on the right side of the bottom of the telescopic rod. A spring is installed outside the telescopic rod.
[0006] Furthermore, the top of the telescopic rod is equipped with rollers. The rollers reduce the friction between the telescopic rod and the rotating plate, thereby reducing wear and extending service life.
[0007] Furthermore, the roller is rotatably connected within a groove. The groove facilitates the movement of the roller, reduces friction between the roller's rotating plates, and extends the equipment's service life. Furthermore, the support includes two vertical beams, the bottom of which are connected to two horizontal beams, and connecting beams are connected to the front and rear sides of each horizontal beam. The horizontal beams and connecting beams improve the stability of the device and extend its service life.
[0008] Further defined, the inclined wire mesh, baffle, and cross plate are present. The inclined wire mesh is installed at the junction of the second and third conveyor lines. The baffle is installed on the second conveyor line. Cross plates are installed on the first, second, and third conveyor lines. In use, when the workpiece falls from the first conveyor line into the second conveyor line, the baffle prevents the workpiece from falling to the edge of the conveyor belt, jamming the conveyor belt, and affecting its normal operation. The cross plates on the first, second, and third conveyor lines separate the workpieces one by one during use, reducing noise caused by friction between the workpieces. The inclined wire mesh at the junction of the second and third conveyor lines provides a buffer zone for the workpieces during use, achieving a noise reduction effect.
[0009] Furthermore, the two vertical beams, two horizontal beams, and connecting beams of the bracket are all made of steel. Steel has high strength, good plasticity and heat resistance, uniform material, and high operational reliability.
[0010] The main advantages of this utility model are: The telescopic mechanism allows the rotating plate to slowly rotate downwards when the workpiece falls onto it, thus allowing the workpiece to fall smoothly onto other conveyor lines. This buffers the workpiece and reduces noise generated at the connection and transfer points of the conveyor lines.
[0011] The lifting mechanism facilitates the transfer of workpieces on different conveyor lines while reducing noise generated during the transfer process.
[0012] 3. The horizontal plates on the conveyor line enable the conveyor belt to stably transport workpieces even when it is inclined, preventing workpieces from piling up due to gravity. They can also fix the position of the workpieces and avoid noise caused by collisions, offsets or overturning of workpieces due to vibration or speed changes during the transport process.

Detailed Implementation
[0014] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.
[0015] like Figures 1 to 6As shown, this utility model discloses a noise reduction structure applied at the connection of a workpiece conveyor line, including a lifting mechanism. The lifting mechanism is installed on the front side of the conveyor line for connecting different conveyor lines. The lifting mechanism includes a rotating plate 5, with a groove 17 at the bottom of the rotating plate 5. A connecting rod 6 is rotatably connected to the rear side of the rotating plate 5. A bracket 8 is installed at the bottom of the rotating plate 5. The bracket 8 includes two vertical beams 9, with two horizontal beams 10 connected to the bottom of the two vertical beams 9. Connecting beams 11 are connected to the front and rear sides of the two horizontal beams 10. The two vertical beams 9, two horizontal beams 10, and connecting beams 11 of the bracket 8 are all made of steel. A telescopic mechanism 13 is installed at the bottom of the bracket 8. The telescopic mechanism 13 includes a cylinder 14, which includes an upper cavity 7. The equipment includes a lower cavity 12 and an outer cavity 25. A first one-way valve 20 is installed on the right side of the bottom of the lower cavity 12, and a first damping valve 21 is installed on the left side. A telescopic rod 15 is installed inside the cylinder 14. A second one-way valve 18 is installed on the left side of the bottom of the telescopic rod 15, and a second damping valve 19 is installed on the right side. A spring 16 is installed on the outside of the telescopic rod 15, and a roller 24 is installed on the top of the telescopic rod 15. The roller 24 is rotatably connected in the slide groove 17. The equipment also includes an inclined iron mesh 4, a baffle 22, and a horizontal plate 23. The inclined iron mesh 4 is installed at the junction of the second conveyor line 2 and the third conveyor line 3. The baffle 22 is installed on the second conveyor line 2. Horizontal plates 23 are installed on the first conveyor line 1, the second conveyor line 2, and the third conveyor line 3.
[0016] During operation, workpieces are transported from the third conveyor line 3 to the second conveyor line 2. An inclined wire mesh 4 is installed at the junction of the third and second conveyor lines 3 and 2, providing a smoother connection between the two lines and reducing noise from the workpieces. Workpieces from the first conveyor line 1 are also transported to the second conveyor line 2 for processing. A lifting and telescopic mechanism is installed at the junction of the first and second conveyor lines 1 and 2. When a workpiece falls onto the rotating plate 5, the plate rotates downwards due to gravity. This downward rotation causes the roller 24 at the top of the telescopic rod 15 to move to the right along the slide 17. The downward rotation of the rotating plate 5 also causes the telescopic rod 15 to move into the cylinder 14. As the cylinder moves downward, spring 16 is compressed, and the second one-way valve 18 opens. Air in the lower chamber 12 of cylinder 14 enters the upper chamber 7 of cylinder 14 through the second one-way valve 18. The remaining gas in the lower chamber 12 enters the outer chamber 25 through the first damping valve 21. When the workpiece moves to the next conveyor line, under the action of spring 16, the telescopic rod 15 moves upward. The roller 24 at the top of the telescopic rod 15 moves to the left along the slide groove 17, causing the rotating plate 5 to rotate upward. Then the second damping valve 19 opens, and air in the upper chamber 7 of cylinder 14 enters the lower chamber 12 of cylinder 14 through the second damping valve 19. The remaining air in the outer chamber 25 enters the lower chamber 12 of cylinder 14 through the first one-way valve 20. The telescopic rod 15 springs back to its original position.
[0017] The aforementioned movement causes the rotating plate 5 to slowly rotate downwards, allowing the workpiece to fall smoothly onto other conveyor lines, thereby reducing the noise when the workpiece falls. Horizontal plates 23 are installed on the first conveyor line 1, the second conveyor line 2, and the third conveyor line 3. During operation, the horizontal plates 23 separate and transport the workpieces one by one, reducing the noise generated by friction between the workpieces and achieving noise reduction. Baffles 22 are also installed at the junction of the first conveyor line 1 and the second conveyor line 2 to prevent the workpiece from falling onto the edge of the conveyor belt and jamming it.
[0018] The above provides a detailed description of a noise reduction structure for use at the connection point of a workpiece conveyor line, as provided by this utility model. The specific embodiments are described only to aid in understanding the method and core concept of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
