Baboon drum-centering mechanism for bamboo breaking machine

Abstract

The invention provides a baboon drum-centering mechanism for a bamboo breaking machine. A front cone in the baboon drum centering mechanism is in threaded connection with a mandrel, a support rod support piece is sleeved in the middle of the mandrel, the peripheral fixation between the support rod support piece and the mandrel can be realized by a flat key, three support rods are respectively hinged in three grooves of the support rod support piece by pin shafts, two edges at the front ends of the three support rods are respectively provided with a tension spring base, and two heads of the three tension springs are respectively hooked on the tension spring bases, so that the three support rods form into a cone body which is front in the front part and large in the back part; after the baboon drum centering mechanism on a baboon drum small head is pushed away from the cross section at which the centers of the three pin shafts are placed by a section of distance, the inner wall of the baboon drum small head is contacted with the support rods; and the baboon drum continuously moves forwards, the inner wall of the baboon drum small head can lead the thee support rods to synchronously swing around the pin shafts, till the three support rods enter the baboon drum and the baboon drum is supported by the tail parts of the three support rods in the baboon drum, the three support rods stop swinging, and the baboon drum and a baboon breaking knife can be centered with each other.

Description

technical field [0001] The invention belongs to the field of bamboo material processing, and mainly relates to a mechanism for accurately centering the bamboo tube and the bamboo cutting knife when the bamboo tube is divided into bamboo slices with equal widths. Background technique [0002] The production process of bamboo summer mat mainly includes: breaking bamboo, splitting, drawing, weaving, sewing, etc., and dividing the bamboo tube into bamboo slices with equal width is the first process of producing bamboo summer mat. When breaking bamboo, the small end of the bamboo tube must be aligned with the bamboo knife and the center of the bamboo tube must be aligned with the center of the bamboo knife to ensure that the bamboo tube is divided into bamboo pieces of equal width. According to the requirement of splitting and wire drawing, the chord length and width B at the inner diameter of the split small-headed bamboo slices shall not be less than 21mm, and then processed in...

AI Technical Summary

Problems solved by technology

At present, the bamboo breaking machines used in China basically do not have an accurate centering mechanism for the bamboo tube. The bamboo tube is manually placed on the cone at the front end of the bamboo knife figure 1 shown), and the size of the cone is determined by the minimum diameter in the range of the inner diameter of the bamboo tube suitable for the number of different blades in the broken bamboo knife. Since the diameter of the cone in each broken bamboo knife cannot be changed, this structure cannot make the bamboo tube Accurate alignment with the center of the broken bamboo knife. Generally, the width of bamboo slices in a bamboo tube is not equal, sometimes the difference is very large, so that some bamboo slices are less than 20mm in width, resulting in different widths of bamboo threads; some bamboo slices The width is very large, which increases the amount of cutting and affects the life of the cutting equipment
