Multipurpose hole scratching device

Abstract

The invention relates to a multipurpose hole scratching device used for solving the problem that hole scratching cutters of a drip irrigation pipe production line cannot be exchanged. The multipurpose hole scratching device is characterized by comprising a multipurpose hole scratching cutter holder, a round-hole-shaped hole scratching cutter, a horseshoe-shaped hole scratching cutter and a linear hole scratching cutter; a hole scratching main shaft installing position is arranged in the multipurpose hole scratching cutter holder and has certain conicity, a cutter installing position with conicity is designed at the upper end of the installing position, and a cutter installing position with threads is designed at the lower end of the installing position; a cavity with conicity is formed in the round-hole-shaped hole scratching cutter, and the front end cutting edge is machined according to the requirement for the sizes of drip openings of drip irrigation pipes; the tail end of the horseshoe-shaped cutter is inlaid in a base, and a horseshoe-shaped cutting edge is formed at the front end; the tail end of the linear cutter is inlaid in the base, and a linear cutting edge is formed at the front end. The hole scratching cutters can be replaced at any time according to needs in the drip irrigation pipe production process, and drip irrigation pipe products with the drip openings in different forms can be produced.

Description

technical field [0001] The invention relates to a plastic product processing equipment, in particular to a multi-purpose slitting device used in the production of drip irrigation pipes, which belongs to the technical field of plastic processing machinery. Background technique [0002] Drip irrigation is an advanced water-saving irrigation technology, which lays a special drip irrigation pipe in the field to water crops. The drip irrigation pipe is made of plastic hose, and its structure is to uniformly stick the dripper on the inner wall of the ordinary plastic hose. The dripper is provided with a water channel and a drip hole leading to the outside of the pipe. The water channels and drip holes on the head drip directly to the roots of the plants. This watering method consumes far less water than the traditional flood irrigation method, and can effectively increase the yield of crops.

Problems solved by technology

[0003] In the drip irrigation pipe production line, one of the most important processes is to open the drip outlet on the outside of the drip irrigation pipe that has been pressed inside the dripper, that is, the dripper is pressed, so that the normal use of the drip irrigation pipe can be guaranteed. At present, domestic and foreign There are three types of drip irrigation pipe drip outlets, which are round hole shape, horseshoe shape and straight shape. The designs of the three types of slitting tools are different and cannot be replaced with each other. How can they be unified so that they can be replaced quickly? At this time, it is necessary to redesign the tool mounting seat, and at the same time, redesign the three types of scribing tools to ensure that they can be installed on the tool holder to meet the multi-purpose needs.
