[0002] The metal products industry encompasses a wide range of sectors, including the manufacture of structural metal products, metal tooling, containers and various metal packaging containers, as well as stainless steel and various household metal products. Before these products undergo fine processing, their surfaces must be pre-cleaned of dust and impurities to ensure the quality and aesthetics of the finished product.

[0003] In the context of traditional transmission technology, cleaning metal surfaces typically requires workers to manually secure the metal using clamping tools, then immerse it in a cleaning solution and manually shake it to achieve the desired cleaning effect. However, due to the stubborn dust and impurities adhering to some metal products, vigorous shaking is required to completely remove them. This not only increases the labor intensity of the manual operation, but is also time-consuming, labor-intensive, and inefficient, making it unsuitable for large-scale production and application. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-Figure 3 A metal product surface cleaning pretreatment device includes a treatment box 1, a liquid storage tank 2 is provided in the treatment box 1, and the liquid storage tank 2 is used to hold cleaning liquid. The liquid storage tank 2 and the treatment box 1 are fixedly connected by a same hose 3. The arrangement of the hose 3 facilitates the discharge of the cleaning liquid from the liquid storage tank 2. At the same time, the liquid storage tank 2 is preferably, but not limited to, provided with a water pump for discharging the cleaning liquid. The water pump discharges the cleaning liquid through the hose 3. This is a mature existing technology and will not be described in detail here. A connecting plate 4 is provided above the treatment box 1;

[0022] Treatment tank 1 is equipped with a first drive mechanism for vertically oscillating liquid tank 2. This mechanism causes the cleaning liquid in tank 2 to oscillate up and down, slapping the metal product, thereby improving cleaning uniformity. Treatment tank 1 is also equipped with a second drive mechanism for lateral oscillation of connecting plate 4, which is equipped with a securing structure for securing the metal product. This mechanism causes the metal product placed in tank 2 to oscillate horizontally, further improving cleaning uniformity.

[0023] Drive structure 1 includes a rotating rod 6 rotatably connected to the inner wall of processing tank 1. A motor 5 is fixedly connected to the outer wall of processing tank 1 for driving rotating rod 6. A pair of cams 7 are fixedly mounted on rotating rod 6, with the cam surfaces of cams 7 contacting the bottom surface of liquid storage tank 2. Driven by motor 5, cams 7 rotate to achieve vertical movement of liquid storage tank 2. A concave plate 8 is fixedly mounted on the inner wall of processing tank 1, to which a vertical rod 9 is fixedly mounted. A block 10 is vertically slidably mounted on vertical rod 9, which is fixedly connected to liquid storage tank 2. A spring 11 is mounted on vertical rod 9, with its ends fixedly connected to block 10 and concave plate 8, respectively. The purpose of spring 11 is not only to ensure the stable downward movement and reset of liquid storage tank 2, but also to provide a certain degree of cushioning and shock absorption for liquid storage tank 2, preventing damage caused by excessive wear due to prolonged up and down movement.

[0024] Drive structure 2 includes motor 2 (12) fixedly connected to the outer wall of processing box 1. A pair of mounting plates (13) are fixedly connected to the top of processing box 1. Drive rods (14) are horizontally slidably connected to mounting plates (13). The two drive rods (14) serve to limit the rectangular gear ring (15), ensuring its stable horizontal movement. The two drive rods (14) are fixedly connected to the same rectangular gear ring (15) on opposite side walls. A collar (16) is fixedly sleeved on the output end of motor 2 (12). A half gear (17) is fixedly connected to collar (16), which meshes with rectangular gear ring (15). Half gears (17) mesh with the symmetrical teeth within rectangular gear ring (15), thereby achieving horizontal reciprocating motion of rectangular gear ring (15) and ensuring the horizontal stability of its motion.

[0025] The fixing structure includes an L-shaped plate 18 fixedly connected to the bottom of the connecting plate 4. A screw 19 is rotatably connected to the connecting plate 4. The bottom end of the screw 19 is rotatably connected to the L-shaped plate 18. A fixing plate 20 is threadedly connected to the screw 19. By rotating the screw 19, the fixing plate 20 moves vertically downward to fix the metal product, preventing the metal product from falling during cleaning.

[0026] The inner wall of the rectangular gear ring 15 is provided with mutually symmetrical teeth, and the half gear 17 is provided on the opposite side of the mutually symmetrical teeth. The position of the half gear 17 is set to ensure the feasibility of the implementation of the entire drive structure 2.

[0027] The L-shaped plate 18 is provided with a sliding opening, and the fixed plate 20 is vertically slidably connected to the sliding opening. The purpose of this arrangement is to ensure that the fixed plate 20 stably moves vertically along the axis direction of the screw 19, thereby ensuring stable clamping and fixing of the metal product.

[0028] The functional principle of this utility model can be explained through the following operation modes:

[0029] When using the device, first, place the metal product to be cleaned on the L-shaped plate 18 on the connecting plate 4, and move the fixing plate 20 downward by screwing the screw 19 to clamp the metal product to ensure that it will not fall during the cleaning process.

[0030] Open the liquid storage tank 2 and add enough cleaning liquid into it.

[0031] Turn on motor one 5 and motor two 12 to start the cleaning process.

[0032] Motor 1 5 drives rotating rod 6, which rotates cam 7 and pulls spring 11, causing liquid reservoir 2 to rock up and down, causing the cleaning liquid to tumble within the reservoir 2 and provide a preliminary cleaning of the metal product. Simultaneously, motor 2 12, through the meshing of half gear 17 and rectangular gear ring 15, drives connecting plate 4 to rock sideways, causing the metal product to rock horizontally as well, further improving cleaning uniformity.

[0033] After cleaning is completed, turn off motor 1 5 and motor 2 12 to stop the operation of the equipment. Then, open the hose 3 to discharge the cleaning fluid in the liquid storage tank 2.

[0034] The screw 19 is turned to move the fixing plate 20 upwards, loosening the metal product, which is then removed from the connecting plate 4. Finally, the device is cleaned and prepared for the next use.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
