[0002] Conveying equipment is a type of mechanical equipment that uses mechanical structures, power units, and control systems to achieve continuous and directional transport of materials, products, or items between different locations. It is widely used in manufacturing, logistics and warehousing, mining, agriculture, and food processing. Its core function is to efficiently and stably transfer items from a starting point to a destination through the cyclical or directional movement of conveyor belts, rollers, chains, and track conveying components. This reduces manual handling costs and improves the automation and efficiency of production or logistics processes. In the material discharge stage of product production, conveying equipment is a key device connecting processing steps with subsequent handling.

[0003] Traditional conveying equipment lacks flexible size adjustment capabilities. When conveying products of different widths and thicknesses, frequent replacement of conveying components or adjustment of the equipment structure are required, resulting in cumbersome and inefficient operation. Furthermore, products are prone to shifting, tilting, or even falling during conveyance due to vibration and high-speed operation, especially lightweight, easily tipped, or surface-damaged products, leading to losses and quality fluctuations. Therefore, we propose a conveying device for product discharge. Utility Model Content

Located on the top plate 4, and used to drive the C-shaped support frame 6 to rise and fall, the product to be received enters from the input end of the conveyor belt 2 and moves towards the output end with the conveyor belt 2. When it is necessary to adjust the correction distance on both sides, the drive component drives the correction frame 13 and the second conveyor roller 14 to move synchronously until the distance between the two conveyor rollers 14 on both sides matches the width of the product. When the product shows a tendency to deviate, the two conveyor rollers 14 on both sides will contact the side of the product, and the symmetrically set correction frame 13 will guide the product back to the center position of the conveyor belt 2 to ensure accurate transmission direction. When it is necessary to adjust the height of the first conveyor roller 7, the lifting component drives the C-shaped support frame 6 to rise and fall in the vertical direction, adjusting the distance between the first conveyor roller 7 and the conveyor belt 2 to be slightly greater than the thickness of the product. During the movement of the product on the conveyor belt 2, the first conveyor roller 7 at the top forms a protective barrier to prevent the product from tilting upwards or falling due to vibration, collision or high-speed transmission, which is especially suitable for lightweight or easily tipped products.

[0018] In this embodiment, the driving component includes: A rectangular slot 15 is formed at the top of the fixing frame 9 and located between two threaded slots 10. A first motor 16 is fixedly installed at the bottom of the fixing frame 9. The output shaft of the first motor 16 extends through the bottom of the fixing frame 9 into the rectangular slot 15 and is fixedly installed with a bevel gear 17. A second bevel gear 18 is meshed with the first bevel gear 17 on both sides of the rectangular slot 15. Two threaded rods 11 are rotatably installed in the two fixing frames 9 respectively. One end of the threaded rod 11 extends through the lower end of the corresponding L-shaped fixing frame 12 and one side of the threaded slot 10 into the rectangular slot 15. 11 is coaxially connected to two bevel gears 18. When the first motor 16 is started, its output shaft drives the bevel gear 17 in the rectangular groove 15 to rotate. The rotating bevel gear 17 drives the two bevel gears 18 to rotate, thereby driving the two threaded rods 11 to rotate synchronously in opposite directions in the threaded groove 10. Under the action of the thread, the rotating threaded rods 11 drive the L-shaped fixing frame 12 to slide in the corresponding threaded groove 10. At this time, the two L-shaped fixing frames 12 move towards or away from each other along the threaded rods 11, driving the correction frame 13 and the conveyor roller 14 to move synchronously until the distance between the two conveyor rollers 14 on both sides matches the product width.

[0019] In this embodiment, both bevel gears 18 and 17 are rotatably connected to the rectangular groove 15. The output shaft of the first motor 16 is rotatably connected to the fixed frame 9 and the rectangular groove 15. The threaded rod 11 is rotatably connected to the rectangular groove 15. The L-shaped fixed frame 12 is threadedly connected to the threaded rod 11, ensuring that both bevel gears 18 and 17 can rotate within the rectangular groove 15. This ensures that the first motor 16 can operate normally on the fixed frame 9. Under the action of the thread, the rotating threaded rod 11 can drive the corresponding L-shaped fixed frame 12 to slide.

The output shaft of hydraulic cylinder 8 is slidably connected to top plate 4. When hydraulic cylinder 8 is powered on and started, hydraulic cylinder 8 extends and retracts. Its output shaft drives C-shaped support frame 6 to rise and fall in the vertical direction, adjusting the distance between conveyor roller 7 and conveyor belt 2.

[0021] In this embodiment, a second motor 19 is fixedly installed on one side of the mounting frame 1. The output shaft of the second motor 19 passes through one side of the mounting frame 1 and is coaxially connected to one of the transmission rollers 3. The output shaft of the second motor 19 is rotatably connected to the mounting frame 1. When the second motor 19 is started, its output shaft directly drives one of the transmission rollers 3 to rotate. One of the transmission rollers 3 drives the other transmission roller 3 to rotate through the conveyor belt 2, thereby making the conveyor belt 2 form a cyclic motion.

[0022] In this embodiment, several conveyor rollers 14 and 7 are arranged in a straight line with equal spacing, which can form uniform lateral restraint and top support for the product, avoid uneven local force causing product displacement or damage, and improve transmission stability and adaptability.

Products ready to be transferred enter from the input end of the conveyor belt 2 and move towards the output end with it. When it is necessary to adjust the alignment spacing on both sides, the first motor 16 is started. Its output shaft drives the bevel gear 17 in the rectangular groove 15 to rotate. The rotating bevel gear 17 drives the two bevel gears 18 to rotate, thereby driving the two threaded rods 11 to rotate synchronously in opposite directions in the threaded groove 10. Under the action of the threads, the rotating threaded rods 11 drive the L-shaped fixing brackets 12 to slide in the corresponding threaded grooves 10. At this time, the two L-shaped fixing brackets 12 move towards or away from each other along the threaded rods 11, driving the alignment bracket 13 and the conveyor rollers 14 to move synchronously until the spacing of the two conveyor rollers 14 on both sides matches the product width. When the product exits... When there is a deviation trend, the two conveyor rollers 14 on both sides will contact the side of the product. The product will be guided back to the center position of the conveyor belt 2 by the symmetrically arranged correction frame 13 to ensure accurate transmission direction. When it is necessary to adjust the height of the conveyor roller 7, the hydraulic cylinder 8 is controlled to extend and retract. Its output shaft drives the C-shaped support frame 6 to rise and fall in the vertical direction, adjusting the distance between the conveyor roller 7 and the conveyor belt 2 to be slightly greater than the product thickness. During the movement of the product on the conveyor belt 2, the top conveyor roller 7 forms a protective barrier to prevent the product from tilting upwards or falling due to vibration, collision or high-speed transmission. It is especially suitable for lightweight or easily tilted products.
