Dehydrating and drying device for chemically plated small shaft

Abstract

The invention discloses a dehydrating and drying device for a chemically plated small shaft, which comprises a dehydrating and drying basket, a shaking type quick dehydrating device and a drum-type dynamic drying device. The dehydrating and drying basket is lined with a stainless steel net inside; the shaking type quick dehydrating device comprises a bracket, a trolley slideway, a centrifugal dehydrating fan and a shaking mechanism, wherein the dehydrating and drying basket is arranged on the trolley slideway supported by the bracket, the centrifugal dehydrating draught fan is arranged below the trolley slideway, the shaking mechanism is matched with the dehydrating and drying basket; and the drum-type dynamic drying device comprises a bracket, drums, a transmission chain, a drying box, a heating tube, a fan, an electronic control cabinet and a driving component, wherein the drums are connected together by the transmission chain, the transmission chain is driven by the driving component, the drying box is arranged above the transmission chain, the heating tube is arranged inside the drying box, and the fan and the electronic control cabinet are arranged outside the drying box. The invention can completely dehydrate the chemically plated small shaft and can ensure even drying temperature at the same time.

Description

Technical field: [0001] The invention relates to the technical field of post-processing equipment for electroless nickel plating products, in particular to a dehydration and drying equipment for small shafts after electroless nickel plating. Background technique: [0002] At present, the small shaft after electroless nickel plating is generally cleaned with pure water, then picked up from the water tank, wrapped with nylon gauze into a ball and placed in a barrel drying machine, and the water is dried by the centrifugal force of the high-speed rotation of the drying barrel. (Similar to spin drying in a washing machine). Then, the dehydrated small shaft is flattened in the mesh belt dryer for drying treatment, and then packaged and shipped out after cooling. [0003] The above-mentioned existing process operations and equipment have the following defects: [0004] (1) Dehydration is difficult to completely clean, especially in the central part after the nylon gauze bandage,...

Problems solved by technology

[0005] (2) When the small shaft is dried, it is placed on the mesh belt of the mesh belt dryer. During the entire drying process, the position of the small shaft on the mesh belt is relatively fixed, and the temperature of the upper surface of the shaft body and the contact with the mesh belt There are still differences in the bottom layer, the drying temperature is not uniform enough, and the defects existing during dehydration cause water traces and yin and yang surfaces with different gloss on the surface of the small shaft body after drying, which seriously affects the product quality

[0006] (3) Poor product quality due to unclean dehydration and uneven drying temperature. When the finished product leaves the factory for a period of time and the user opens the package for assembly, they will find tiny rust spots and yellow spots on the surface of the shaft, especially during the rainy season. It is more serious, which leads to disputes such as return and repair, which is costly and time-consuming, and seriously interferes with normal production
