During the degreasing process, the oil on the roller will remain in the liquid tank and the degreasing liquid, and the oil will float on the surface of the liquid. When the roller is taken out of the liquid tank, the oil will stick to the roller. The effect of degreasing is not good, and when there is a lot of oil in the tank, it will also greatly affect the effect of degreasing the roller, which will lead to a poor effect of electrogalvanizing the roller

Embodiment 1
[0058] Embodiment one: refer to figure 1 , is a roller electrogalvanizing production line disclosed by the present invention, comprising a gantry 1, a pre-treatment tank group 2 is arranged under the gantry 1, and the pre-treatment tank group 2 includes chemical degreasing tanks arranged in sequence along the running direction of the moving vehicle 4 210, electrolytic degreasing tank 220, derusting tank 230, pickling tank 240 and alkali cleaning tank 250, cleaning tanks 3 are arranged between adjacent tank bodies, after the rollers are degreased in each link, the rollers are It needs to enter the cleaning tank 3 for cleaning.
[0059] refer to figure 1 , the gantry 1 is slidingly connected with a mobile car 4, and the gantry 1 is provided with a double-speed chain, the mobile car 4 is connected with the double-speed chain, and the mobile car 4 can drive the roller to move on the gantry 1.
[0060] refer to figure 2 , the mobile car 4 is provided with a lifting structure 5 ...
Embodiment 2
[0080] Embodiment two: a kind of electrogalvanizing production process of roller, comprises the following steps:
[0081] 1) Loading, hang the electroplating roller on the mobile car 4;
[0082] 2) Cleaning, at least 5 times, each time at least 2 minutes;
[0083] 3) Physical degreasing, use the oil scraper 23 to scrape off the oil on the outside of the roller;
[0084] 4) Chemical degreasing, chemical degreasing in the solution, sodiumhydroxide 30-50G / L, industrial detergent 0.5-1ML / L, water 70-125G, the temperature during cleaning is 50-60°C;

Abstract
The invention relates to an electrogalvanizing production line for rollers and its production process. It includes a gantry, and a pre-treatment tank group is arranged under the gantry. The pre-treatment tank group includes chemical degreasing tanks, electrolytic degreasing tanks, For the oil tank, the rust removal tank, the pickling tank and the alkali cleaning tank, cleaning tanks are arranged between adjacent tank bodies, and an oil stain removal structure and an oil stain absorption structure are arranged above the chemical degreasing tank. It specifically includes the following steps: feeding, hanging the electroplating roller on the mobile car; cleaning; physical degreasing; chemical degreasing, etc. The invention has the characteristics that the roller needs to be physically degreased before chemical degreasing, and the oil stain on the outer side of the roller can be removed by using the oil stain removal structure and the oil stain absorption structure in the physical degreasing process, which can fully remove the oil stain on the outer side of the roller, so that The effect of degreasing is better.
Description
technical field [0001] The invention relates to the technical field of roller electroplating equipment, in particular to an electrogalvanizing production line for rollers and a production process thereof. Background technique [0002] Electroplating is the process of plating a layer of other metals or alloys on the metal surface using the principle of electrolysis. Using electrolysis to make the metal surface adhere to a layer of film, so as to prevent metal oxidation, improve wear resistance, conductivity, light reflection, and corrosion resistance. sex and enhance the aesthetic effect. The surface of the product is electroplated with acid zinc and has a beautiful appearance, and the electroplated alkali zinc has strong corrosion resistance. [0003] The electroplatingproduction line in the prior art is relatively mature. For example, the invention patent with the notification number CN104389008B is specifically an electroplating device. It has an electroplating producti...
