Outer box pre-heating device and method

Abstract

The invention relates to the technical field of pipe production equipment and provides an outer box pre-heating device which utilizes external hot air to heat and dry a workpiece automatically. The outer box pre-heating device comprises a machine frame and an air supply pipe system, wherein the air supply pipe system sequentially comprises a fan, an exchanger, a main air duct and a plurality of branch air ducts. The main air duct is connected with the plurality of the branch air ducts, each branch air duct is provided with an air outlet, and the air outlets are formed in the machine frame. According to the outer box pre-heating device, the external hot air can be used for heating and drying the workpiece automatically, energy is saved, and production cost is reduced. Meanwhile, the workpiece only needs to be replaced simply and manually, other operations are all completed by the device, the operations which are difficult to complete manually can be completed, the automation degree is high, labor intensity is reduced, time and effort are saved, labor cost is saved, production safety is guaranteed, operation is simple and convenient, and heating and drying efficiency is improved. Meanwhile, the invention further provides an outer box pre-heating method.

Description

technical field [0001] The present invention relates to the technical field of pipe production equipment, and more specifically, to an outer box preparatory heating equipment and method. Background technique [0002] In the prior art, the pipe needs to be heated and dried during the production process. At present, most of the pipes are heated and radiated by heating equipment such as heating furnaces, so that the pipes are heated and dried, which consumes more heat and increases production costs. At the same time, many processes need to be processed manually, which is difficult to operate, increases labor intensity, is time-consuming and labor-intensive, and has low drying efficiency. Contents of the invention [0003] The present invention aims to solve the above-mentioned technical problems at least to a certain extent. [0004] The object of the present invention is to provide an outer box preparatory heating device which uses external hot air to automatically heat an...
