Method for promoting discharging stabilization of reinforced polypropylene (HRPP) double-wall corrugated pipe for buried drainage and pollution discharge

Abstract

The invention provides a method for promoting discharging stabilization of a reinforced polypropylene (HRPP) double-wall corrugated pipe for buried drainage and pollution discharge, and belongs to thetechnical field of production of pipes. The discharging device comprises a support frame, support legs, a driving device shell, a driven device shell, discharging roller support seats, discharging rollers, a material bouncing rack and a buffer mechanism, wherein rubber protruding strips are arranged on the surfaces of the discharging rollers, so that the static friction force between the discharging rollers and a drainage pipe can be increased, and the impact between the drainage pipe and the discharging rollers can be relieved through the elasticity of the rubber protruding strips; by arranging a sliding seat, damage of the elastic material to an air cylinder is reduced, and by arranging an oil storage bin and oil supply rollers at the bottom end of the sliding seat, the sliding smoothness of a sliding block and a sliding groove can be improved; by arranging an end aligning plate and the buffering mechanism, the ends of the drainage pipe can be kept aligned, the impact force generated when the drainage pipe is aligned can be reduced, and the end of the drainage pipe and the buffering plate are prevented from being damaged in the collision process; and by arranging guide reinforcing blocks and balls, the service life of a guide movable rod can be prolonged.

Description

technical field [0001] The invention belongs to the technical field of pipe material production, and specifically relates to a reinforced polypropylene (HRPP) double-wall corrugated pipe used for buried drainage and sewage discharge to promote the stability of blanking. Background technique [0002] Drainage pipes are widely used in municipal road drainage, agricultural irrigation and household drainage. Drainage pipes can be divided into polymer drainage pipes, concrete material drainage pipes and reinforced concrete material drainage pipes according to their materials. Existing drainage pipes mainly use automated production equipment to complete the production steps of feeding, grinding, cutting, and blanking. [0003] In the existing automatic production steps of drainage pipes, blanking is the last link in the whole production process. In this link, the drainage pipe is bounced to the designated position through the blanking roller and the spring material frame to realiz...

Problems solved by technology

[0003] In the existing automatic production steps of drainage pipes, blanking is the last link in the whole production process. In this link, the drainage pipe is bounced to the designated position through the blanking roller and the spring material frame to realize blanking; but the existing blanking The production equipment still has the following technical problems in the process of use: First, the surface of the feeding drum is in direct contact with the drainage pipe. After a long contact time, the surface of the feeding drum is partially smooth, which leads to insufficient transmission force of the feeding drum to the drain pipe. , to reduce the transmission efficiency. In addition, the drain pipe is a rigid pipe with a certain weight. When the drain pipe is conveyed on the surface of the feeding drum, it will collide, which will cause damage to the pipe and the surface of the feeding drum; The middle does not have the function of aligning the ends of the drain pipes, so the ends of the drain pipes entering the area of ​​the bullet rack are uneven; the third is that in the bullet delivery device, since the position of the fulcrum of the bullet delivery frame remains unchanged, in order to drain the water smoothly The tube is ejected, and the cylinder needs to be installed obliquely. When the cylinder is installed obliquely, it will accelerate the damage of the cylinder.
