Manual screw type tension device applied to waste treatment of pickling line inlet

Abstract

The invention discloses a manual screw type tension device applied to waste treatment of a pickling line inlet. The manual screw type tension device is mainly characterized in that the left end of a fixing support is mounted on a left stand column in a welding manner, and the right end of the fixing support is mounted on a right stand column in the welding manner; the left end of an inclined support is fixedly mounted on the left stand column, and the right end of the inclined support is fixedly mounted on the right stand column; the lower end of a left adjusting screw rod is fixedly mounted on the fixing support by a bolt and nuts, and the upper end of the left adjusting screw rod is fixedly mounted on the inclined support; a left adjusting nut and the left adjusting screw rod are matched, and the left adjusting nut is fixedly mounted on a bearing seat; the lower end of a right adjusting screw rod is fixedly mounted on the fixing support by a bolt and nuts, and the upper end of the right adjusting screw rod is fixedly mounted on the inclined support; a right adjusting nut and the right adjusting screw rod are matched, and the right adjusting nut is fixedly mounted on the bearing seat; a counter weight roller is mounted on the bearing seat by a bearing, a right reversing roller and a left reversing roller are located at the upper part of the inclined support, a belt is mounted on the right reversing roller, and the belt is mounted on the left reversing roller after passing through the counter weight roller.

Description

technical field [0001] The invention relates to the technical field of pickling devices, in particular to a manual screw tensioning device used for waste treatment at the entrance of a pickling line. Background technique [0002] The pickling inlet waste treatment device is the main component of the pickling unit, and it is responsible for handling the out-of-tolerance parts of the hot-rolled raw material coil head and tail to ensure the reliability of welding. The waste processing device consists of double shears, waste pinch rollers, waste pushing device and belt conveyor, wherein the waste pushing device and belt conveyor are installed perpendicular to the center line of the unit. [0003] The belt conveyor in the waste processing device originally used a vertical heavy hammer tensioning device. This structure does not have a heavy hammer box, so the tension cannot be adjusted. The belt tension is not enough, resulting in frequent slippage of the drive roller; the guide r...

Problems solved by technology

[0003] The belt conveyor in the waste processing device originally used a vertical heavy hammer tensioning device. This structure does not have a heavy hammer box, so the tension cannot be adjusted. The belt tension is not enough, resulting in frequent slippage of the drive roller; the guide rails on both sides The length is not long enough, and the maximum tension stroke of the conveyor belt cannot be guaranteed after the belt is deformed and elongated; the machining accuracy of the roller is not high, the surface of the roller body is tapered, and the belt is easy to run off
