[0004] However, in the above-mentioned patent, it is convenient to remove unqualified controlled metals, and stably convey metal pipe products intermittently, prevent the metal pipe products from being placed in a mess during the conveying process, and at the same time prevent the metal pipe products from falling when the conveying device is impacted by external forces, resulting in the inability to perform subsequent processing, thereby reducing the processing efficiency. However, there are still problems. When the metal products are being transported, the metal products may be displaced due to vibration or gravity, resulting in inaccurate positions during the processing. At the same time, if the metal products fall during the conveying process, it may cause equipment damage, worker injuries or other safety accidents. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a conveying device for metal product processing, which solves the problems raised in the above background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A conveying device for metal product processing, including a machine shell.

One end of the push rod is fixedly installed on the side of the L-shaped pressing plate close to the rotating column ring. Collar B is fixedly installed at the other end of the push rod. When the connecting rod moves, it will drive collar A to move. When collar A moves, it will cause inner column A to slide inside collar A. When inner column A slides, it will drive the rotating column ring to rotate. When the rotating column ring rotates, it will drive inner column B to move.

[0013] According to the above technical solution, a soft sheet is provided at the water outlet of the spraying pipe. The first through groove of the liquid box communicates with the second through groove of the extrusion box. When the liquid enters the spraying pipe, when the pressure is sufficient, the liquid will pass through the soft sheet and be sprayed outwards.

[0014] Inner column A contacts the inner wall of collar A, and inner column B contacts the inner wall of collar B. When inner column B moves, it will drive collar B to move, enabling the push rod to perform a reciprocating motion.

[0015] The present invention provides a conveying device for metal product processing. It has the following beneficial effects: (1) In this invention, when a metal product is placed above the pressure plate, the pressure plate will move downward. When the pressure plate moves downward, it will compress the elastic columns on the bottom plate below. When the elastic columns move, they will drive the inclined head rod to move. When the metal product is being conveyed, it can avoid displacement due to the vibration of the conveyor belt or the action of gravity, resulting in inaccurate position during transportation. At the same time, it also avoids the movement or dropping of the metal product, which may damage the conveying device itself and increase the cost of maintenance and replacement.

[0016] (2)In this invention, when the narrow rack moves, it drives the gear to rotate. When the gear rotates, it drives the circular shaft to move. When the circular shaft moves, it drives the small shaft of the small gear meshing with the rear tooth groove to rotate on the triangular prism. During the transportation of metal products, it can prevent the transported items from falling when the staff cannot quickly take them out, which may cause physical damage to the workpieces, affect the quality of their subsequent processing or use, lead to the need for reprocessing or scrapping, and also cause obstacles in the subsequent logistics link, affecting the delivery time and customer satisfaction.

[0017] (3)In this invention, when the connecting rod moves, it drives the collar A to move. When the collar A moves, it causes the inner column A to slide within the collar A. When the inner column A slides, it drives the rotating column ring to rotate. When the rotating column ring rotates, it drives the inner column B to move, preventing the oxidation and corrosion that occur when metal products are exposed to a humid or chemical environment for a long time, damaging the quality and appearance of the metal products, preventing the decline of product quality and production efficiency, and avoiding the decline of the enterprise's competitiveness in the market.

[0028] A soft sheet is provided at the water outlet of the spray pipe 607. The first through groove of the liquid box 606 communicates with the second through groove of the extrusion box 608.

[0030] During operation: Start the conveyor belt 2 inside the motor housing 1. When the conveyor belt 2 rotates, it drives the roller 3 to rotate. When a metal product is placed above the pressure plate 401, it causes the pressure plate 401 to move downward. When the pressure plate 401 moves downward, it compresses the elastic column 402 on the bottom plate 403 below. When the elastic column 402 moves, it drives the inclined head rod 406 to move.

When the lifting plate 501 moves, it drives the telescopic rod 506 on the force-bearing plate 504 to move, lifting the metal product above. After the metal product is taken down, the narrow rack 505 moves in the direction close to the locking plate 509 due to the elastic force of the second spring between it and the fixed plate 508, causing the lifting plate 501 to descend.

[0032] When the lifting plate 501 moves, it drives the lifting rod 601 to move. When the lifting rod 601 moves, it drives the connecting rod 602 to move. When the connecting rod 602 moves, it drives the collar A603 to move. When the collar A603 moves, it causes the inner column A612 to slide inside the collar A603. When the inner column A612 slides, it drives the rotating column ring 604 to rotate. When the rotating column ring 604 rotates, it drives the inner column B610 to move. When the inner column B610 moves inside the collar B605, when the inner column B610 moves inside the collar B605, it drives the collar B605 to move reciprocally. When the collar B605 moves, it drives the push rod 611 to move. When the push rod 611 moves, it drives the L pressing plate 609 to move. When the L pressing plate 609 moves inside the extrusion box 608, it squeezes the liquid entering from the upper liquid box 606 into the spraying pipe 607.
