Description

Technical Field

[0001] This invention relates to a galvanized product production line device, and more particularly to an automatic immersion galvanized product production line and its production method, belonging to the field of galvanized sheet processing. Background Technology

[0002] Zinc plating involves attaching a layer of zinc to the surface of a metal to protect it. Zinc is a very reactive metal and oxidizes extremely easily. However, zinc oxide is not a loose powder like iron oxide; instead, it is a dense surface layer. This zinc oxide layer prevents the internal zinc from further oxidizing. When the surface of a galvanized steel sheet is damaged, exposing the underlying iron surface, zinc, being more reactive than iron, will oxidize before the iron, according to the principle of a chemical battery. This protects the iron layer from damage. Various devices are used in metal galvanizing, but they all involve sending the metal into a zinc-containing bath for chemical and physical reactions.

[0003] According to Chinese patent document CN112267083B, an automatic immersion galvanizing production line is provided, which can automatically convey products, saving time and labor. The production line includes a base plate and support arms, with support arms connected to both sides of the top of the base plate; brackets, with brackets connected to both sides of the rear of the base plate; a drying mechanism connected to one side of the base plate; a conveying mechanism connected between the brackets; and a lowering mechanism connected between the conveying mechanism and the brackets. Through the cooperation of the drying mechanism, conveying mechanism, and lowering mechanism, products can be automatically conveyed and galvanized, eliminating the need for continuous manual conveying, thus saving labor costs. A shaking mechanism can shake the galvanized products, ensuring more thorough galvanizing.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, the aforementioned equipment, when in use, places the product to be galvanized on a component of the conveying mechanism. As the transmission mechanism is activated, the product rotates until it comes into contact with the galvanizing solution, thus galvanizing the product. It is then conveyed to the drying mechanism for drying. Workers can then remove the dried product or place it on hanging rods. Activating the reduction motor causes the first roller, conveyor belt, hanging rods, and product to rotate continuously. With the assistance of the lowering mechanism, the product is galvanized. The method of placing the product to be galvanized in this device is relatively simple; the product is placed on the device without being secured. This means that the galvanized product cannot be subjected to external force; otherwise, it is highly likely to detach from the device and fall to the ground. Furthermore, if the machine operates too fast, the product may shift and fall at any time, posing a certain degree of danger.

[0005] Therefore, it is urgent to improve the automated immersion galvanizing production line to solve the above-mentioned problems. Summary of the Invention

[0006] The purpose of this invention is to provide an automated immersion galvanizing product production line and its production method. This method involves rotating two stop levers onto a recessed frame, where each stop lever contacts a limiting block, thus positioning the clamping components on two chains. The product is then placed between two clamping blocks fixedly connected to the two clamping components. Two hydraulic rods drive a sliding frame to slide within a sliding groove. When the pin slides into the pin nut, a first motor is activated, driving a threaded rod to rotate. During rotation, the threaded rod drives a slider to slide forward within a sliding box. Two first connecting rods push... When one end of each of the two No. 2 connecting rods rotates outward, the other ends of the two No. 2 connecting rods rotate inward. The clamping components on both sides move synchronously, thereby driving the two clamping blocks on each side to clamp the product. The two hydraulic rods return to their initial positions, thereby driving the pins to disengage from the pin nuts and turning the two stop rods away from the limit blocks. The No. 2 motors are then started, driving the two conveyor chains to rotate and then move into the material box for the subsequent galvanizing process. During this process, the clamping components firmly clamp the product and will not disengage from the conveyor chains during the subsequent galvanizing process, ensuring the stability of the product.

[0011] Preferably, the output ends of the two No. 1 motors are connected to rotating shafts, and each of the two rotating shafts is fixedly connected to a pin at one end away from the No. 1 motor, and the pin is movably connected to the pin nut.

[0012] Preferably, each of the two sliding platforms has a hydraulic rod on its vertical inner wall, and the movable ends of the two hydraulic rods are respectively fixedly connected to one side of the sliding frame.

[0013] Preferably, a hinge block is fixedly provided on the upper surface of one side of each of the two sliding platforms, and a stop bar is hinged to each of the two hinge blocks. A recess is fixedly provided on the upper surface of one side of each of the two sliding platforms, and the two recesses are movably connected to the two stop bars respectively.

A second motor is provided on each shelf, and the output ends of the two second motors are respectively fixedly connected to one of the gears. Anti-splash plates are fixedly connected to the bottom of the outer side wall of the two brackets, and the two anti-splash plates are respectively located at the output ends of the two second motors.

[0016] A production method for an automated immersion galvanizing production line includes the following steps:

[0017] S1: First, rotate the two levers onto the recessed frame, and the two levers contact the limit blocks respectively to position the clamping components on the two chains. Then, place the product between the two clamping blocks that are fixedly connected to the two clamping components respectively.

[0021] This invention has at least the following beneficial effects:

[0022] 1. By rotating the two stop levers onto the recessed frame, the two stop levers contact the limit blocks, positioning the clamping components on the two chains. Then, the product is placed between the two clamping blocks fixedly connected to the two clamping components. The two hydraulic rods drive the sliding frame to slide within the sliding groove. When the pin slides into the pin nut, the first motor is started, driving the threaded rod to rotate. During rotation, the threaded rod drives the slider to slide forward within the sliding box. The two first connecting rods push one end of the two second connecting rods outwards, causing the other end of the two second connecting rods to rotate. The ends rotate inwards, and the clamping components on both sides move synchronously, thereby driving the two clamping blocks on each side to clamp the product. The two hydraulic rods return to their initial positions, thereby driving the pins to disengage from the pin nuts and turning the two stop bars away from the limit blocks. The second motor is started, driving the two conveyor chains to rotate, and then the product is transferred to the material box for the subsequent galvanizing process. During this process, the clamping components firmly clamp the product and will not disengage from the conveyor chains during the subsequent galvanizing process, ensuring the stability of the product and greatly increasing the safety of surrounding workers and the stability of the product during its movement.
