Thread Content

Recently, the patent for the “Coating Trimming Device for Insulated Pipe Production Lines” applied for by Hebei Huidong Pipeline Co., Ltd. was granted. The abstract indicates that the present invention provides a coating trimming device for a insulation pipe production line, which includes a bracket, a sliding frame, a fixed cover, a grinding roller, and a negative pressure collection module. The top of the bracket features a limiting slide groove. The slider is slidably arranged in the sliding groove. The fixed cover is fixed to the extended end of the slide frame; it has a housing chamber with an open end facing the pipe to be trimmed, and arc-shaped contact parts are provided at both ends of the housing chamber. Vents are provided at the upper and lower ends of the fixed cover, respectively. The fixed cover is also equipped with an outlet. The negative pressure collection module is connected to the outlet, and it can use negative pressure to draw out the insulation layer powder formed inside the fixed cover. The coating trimming device for the insulation pipe production line provided by the present invention, after the fixed cover makes contact with the insulation layer, has only two air outlets that are in communication with the outside environment. The negative pressure collection module creates negative pressure in the containment chamber; air flow then moves into this chamber through the two air outlets, thereby sucking out the fallen insulation layer powder at the outlet, ensuring its collection.
