Device for grinding inside of plastic pipe

Abstract

The invention discloses a device for grinding the inside of a plastic pipe. The device for grinding the inside of the plastic pipe comprises a passing rod, wherein a top cover is arranged above the passing rod; the top cover is fixedly connected with a connecting rod through a top screw bolt; two screw nuts are arranged on the top cover; a position limiting block is arranged at one side of the connecting rod; a clamp block is arranged above the position limiting block; a short rod is connected with the bottom of the clamp block; a passing block is arranged under the connecting rod, and is fixedly connected with a pull rod; one end of the pull rod is connected with a connecting block; an upper press roller is arranged above the connecting block; a lower press roller is arranged under the connecting block. T passing rod is arranged inside the device, so that the device can be continuously used through manually pulling the passing rod during the power failure; in addition, the passing rod penetrates through the whole device, so that the integral structure of the device is more stable. The upper press roller and the lower press roller are respectively installed at the upper end and the lower end of the connecting block, so that in the use process of the device, the upper and lower pipe walls can be subjected to grinding treatment on the plastic pipes, and the efficiency is higher.

Description

technical field [0001] The present invention relates to a device for grinding the interior of a plastic pipe. Background technique [0002] The existing grinding device for the inner wall of the plastic pipe has certain defects in use, including that the grinding device can only grind the upper or lower wall of the plastic pipe wall at the same time, and does not have the ability to simultaneously grind the upper and lower pipe walls. The function of simultaneous grinding is performed, so grinding is time-consuming, and the existing device for grinding the inside of the plastic pipe is generally controlled by electricity, and the device cannot continue to be used in the event of a power outage. Therefore, in view of the above problems, a device for grinding the inside of a plastic pipe is proposed. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a device for grinding the inside of a plastic pipe in order to solve the above problems. ...
