[0002] Tinplate printing is a process in the metal packaging industry that transfers the designed patterns and texts to the surface of metal materials through printing technology. The blanks used in canning tinplate are usually tinplate or other metal materials, which often need surface treatment before printing to ensure good printing quality and subsequent corrosion resistance. Pickling is one of the common surface treatment methods, which is used to remove oxides and other impurities on the metal surface so that the tinplate ink can adhere better.

[0003] The existing surface pickling method for blanks for canning tinplate generally adopts a pickling tank filled with pickling solution (such as hydrochloric acid, sulfuric acid, etc.). The blanks are immersed in the tank for a long time to remove the oxide layer and impurities on the surface by chemical reaction. This process relies on the natural progress of chemical reactions, resulting in a long processing time and relatively low efficiency. It not only takes up more production time, but also may increase energy consumption and chemical consumption. At the same time, it limits the improvement of overall production efficiency, which is not conducive to meeting the modern manufacturing industry's demand for high efficiency and low cost.

The pickling tank 1 of this structure can be operated by placing the blank to be pickled inside the blank frame 2. When the stepper motor 6 is driven on the guide block 5, it will drive the connecting rod 7 to swing back and forth in an orderly manner. When the connecting rod 7 swings back and forth, it can synchronously drive the blank frame 2 to rock back and forth inside the pickling tank 1, and the pushing mechanism 8 can drive the guide block 5 to move horizontally at the bottom of the cross frame 4, so that the blank frame 2 can also rock left and right to a certain extent inside the pickling tank 1. In this way, when the blank frame 2 shakes regularly along multiple axes, the contact between the acid and the surface of the blank can be enhanced, which promotes the reaction. At the same time, the circulating spray mechanism 9 can extract the acid liquid inside the pickling tank 1, and spray it back to the surface of the blank at high pressure after filtering, forming a continuous impact, accelerating the peeling of the oxide layer, thereby solving the problems of low efficiency, high cost, and heavy environmental burden in the traditional pickling method. The pushing mechanism 8 includes a push block 81, a through port 82 and a cylinder 83. The through port 82 is opened on the cross frame 4 and corresponds to the position of the guide block 5. The push block 81 is inserted into the through port 82 and its bottom end is welded and fixed to the top of the guide block 5. The cylinder 83 is fixed to one side of the top of the cross frame 4 by bolts, and the output end of the cylinder 83 is fixedly connected to the top of the push block 81. When the cylinder 83 of this structure is driven, it will drive the push block 81 to move horizontally in the through port 82. When the push block 81 moves horizontally, it can synchronously drive the guide block 5 The block 5 moves laterally at the bottom of the horizontal frame 4 to realize the function of the blank frame 2 shaking left and right within a certain range inside the pickling tank 1. The circulating spray mechanism 9 includes a suction pipe 91, a circulating pump 92, a filter box 93, a hose 94 and a high-pressure injection pipe 95. The circulating pump 92 and the filter box 93 are fixedly installed on the top of the horizontal frame 4 by fixing bolts. The liquid outlet end of the circulating pump 92 and the liquid inlet of the filter box 93 are connected with a pipe body. The suction pipe 91 is connected to the liquid suction end of the circulating pump 92 and its bottom end extends into one side of the inside of the pickling tank 1. The high-pressure injection pipe 95 is horizontally installed at the bottom of the horizontal frame 4 through a bracket. A plurality of high-pressure nozzles are evenly arranged at the bottom of the high-pressure injection pipe 95. The hose 94 is connected between the liquid outlet of the filter box 93 and the liquid inlet of the high-pressure injection pipe 95.When the circulation pump 92 of this structure is started, the acid liquid inside the pickling tank 1 can be transported to the inside of the filter box 93 through the suction pipe 91. The filter box 93 filters the acid liquid and then transports it to the high-pressure injection pipe 95 through the hose 94. The high-pressure injection pipe 95 can perform high-pressure injection on the blank inside the blank frame 2 through a plurality of nozzles at the bottom to achieve a better pickling effect, significantly shorten the pickling time, and help reduce the amount of acid liquid and energy consumption. The outer walls of both sides of the pickling tank 1 are provided with sleeves 10 that match the support rod 3 structure, and the outer side of one of the sleeves 10 is provided with a hydraulic cylinder 11 fixedly installed through a support block. The output end of the hydraulic cylinder 11 is fixedly connected to the outer side of the corresponding support rod 3 through a connecting piece. When the hydraulic cylinder 11 of this structure is driven, it will drive one of the support rods 3 to extend upward along the sleeve 10. In order to realize the overall lifting function of the structure on the horizontal frame 4, the horizontal frame 4 can quickly lift the blank frame 2 to the outside of the pickling tank 1, so that the blank can be taken and placed in the blank frame 2 in real time. The bottom end of the inside of the pickling tank 1 is provided with a liquid guide plate 12 with an inclined structure, and the lower side of the liquid guide plate 12 corresponds to the position of the suction pipe 91. The liquid guide plate 12 of this structure can collect the acid liquid inside the pickling tank 1 to the side corresponding to the suction pipe 91, so that the circulating spray mechanism 9 can absorb it through the suction pipe 91. A plurality of partitions 13 are evenly arranged on the bottom inner wall of the blank frame 2, and a plurality of overflow holes are evenly arranged on the partitions 13. The partitions 13 of this structure can separate a plurality of placement spaces inside the blank frame 2, so that the blanks can be placed more evenly, avoiding accumulation at the same position during shaking to affect the pickling effect.

[0019] Working principle: When using the surface pickling device for canning tinplate, first place the blank to be pickled inside the blank frame 2 and place it evenly through the partition 13, then add an appropriate amount of acid solution inside the pickling tank 1 and start the stepper motor 6. When the stepper motor 6 is driven on the guide block 5, it will drive the connecting rod 7 to swing back and forth in an orderly manner. When the connecting rod 7 swings back and forth, it will drive the blank frame 2 to shake back and forth inside the pickling tank 1. At the same time, the cylinder 83 of the pushing mechanism 8 is started. When the cylinder 83 is driven, it will drive the push block 81 to move horizontally in the through port 82. When the push block 81 moves horizontally, it can synchronously drive the guide block 5 to move horizontally at the bottom of the cross frame 4. In this way, the blank frame 2 will also shake left and right to a certain extent inside the pickling tank 1 to enhance the acid solution and the blank surface. The contact of the surfaces promotes the reaction, and the circulation pump 92 is started again. When the circulation pump 92 is started, the acid in the pickling tank 1 is transported to the inside of the filter box 93 through the suction pipe 91. The filter box 93 filters the acid and then transports it to the high-pressure injection pipe 95 through the hose 94. The high-pressure injection pipe 95 uses a plurality of nozzles at the bottom to perform high-pressure injection on the blank inside the blank frame 2, thereby continuously impacting and pickling. When the blank is pickled and needs to be taken out, the hydraulic cylinder 11 is started. When the hydraulic cylinder 11 is driven, it will drive one of the support rods 3 to extend upward along the sleeve 10 to drive the cross frame 4 to rise and fall. When the cross frame 4 is lifted to a suitable position, the billet frame 2 can be raised to the outside of the pickling tank 1, so as to take the billet inside the billet frame 2, thereby completing a series of tasks.
