The fixing seats 104 on the installation box 102 and the fixing seats 104 on the L-shaped installation rod 103 are used to install the steel-plastic conversion pipe fittings 105 to be baked.

[0028] The baking assembly includes a baking box 106 and a turntable 107. The turntable 107 is slidably arranged on the workbench 101. The sliding direction of the turntable 107 is perpendicular to the sliding direction of the installation box 102. The baking box 106 is rotatably installed on the turntable 107. The baking box 106 is provided with a plurality of mounting holes 108. The steel-plastic conversion pipe fitting 105 is used to be connected with the fixing seat 104 on the L-shaped mounting rod 103 after passing through the mounting holes 108. The steel-plastic conversion pipe fitting 105 is provided with a heat shrink sleeve 109. The baking box 106 is used to bake the heat shrink sleeve 109 on the steel-plastic conversion pipe fitting 105.

[0029] The utility model mainly comprises a workbench 101, a baking assembly and an installation assembly, and the baking assembly and the installation assembly are used to slide with the workbench 101; in actual use, the staff first puts the heat shrink sleeve 109 on the steel-plastic conversion pipe fitting 105, and then controls the driving device to make the installation box 102 close to the baking box 106, at this time, the fixing seat 104 on the installation box 102 is located in the installation hole 108 on the baking box 106, and then connects the steel-plastic conversion pipe fitting 105 with the fixing seat 104 located inside the installation hole 108, and then installs the other end of the steel-plastic conversion pipe fitting 105 on the fixing seat 104 on the L-shaped mounting rod 103, at this time, the end of the steel-plastic conversion pipe fitting 105 is located inside the baking box 106, and then according to the installation method of the first steel-plastic conversion pipe fitting 105, install the remaining steel-plastic conversion pipe fittings 105 on each group of fixing seats 104, after the installation is completed, open the baking box 106, and then At the same time, the driving device is controlled to move the installation box 102 on the workbench 101 in the direction away from the baking box 106. At this time, the baking box 106 bakes the heat shrink sleeve 109 on the surface of the steel-plastic conversion pipe fitting 105. The heat shrink sleeve 109 shrinks due to the heat and tightly adheres to the steel-plastic conversion pipe fitting 105. When the bending part of the steel-plastic conversion pipe fitting 105 is close to the installation hole 108, the baking box 106 needs to be rotated. With the rotation of the baking box 106 and the sliding of the installation box 102, the baking box 106 bakes the bending part of the steel-plastic conversion pipe fitting 105 until the heat shrink sleeve 109 on the entire steel-plastic conversion pipe fitting 105 is baked. Then, the steel-plastic conversion pipe fitting 105 is removed to complete the installation of the anti-corrosion coating of the steel-plastic conversion pipe fitting 105; the advantage of this arrangement is that the heat shrink anti-corrosion coating can be installed on the batch-bent steel-plastic conversion pipe fittings 105, so that the efficiency of the anti-corrosion treatment of the steel-plastic conversion pipe fittings 105 is higher.
