Automatic silkworm cocoon hole cutting machine and hole cutting method

Abstract

The invention discloses an automatic silkworm cocoon hole cutting machine and a hole cutting method, the radial direction of a disk surface of a cocoon separating disk is provided with 2 rectangular slots that are symmetrical along the center of the cocoon separating disk, a horizontal cocoon conveying belt is positioned below the cocoon separating disk, the left end of the cocoon conveying belt is positioned under the cocoon separating disk, the right end of the cocoon conveying belt is tightly connected with the left end of a cocoon conveying passage, a cocoon pushing mechanism is arranged at an upper right position of the cocoon conveying passage, and a photosensitive sensor is installed on the cocoon pushing mechanism; a conveyor belt, an active roller wheel and a passive roller wheel are arranged on the right side of the cocoon conveying passage, a fixture component is fixedly connected on the conveyor belt, a positioning and clamping mechanism is arranged at a conveyor belt position between the active roller wheel and the passive roller wheel, a pushing plate that pushes the fixture to make the fixture open is positioned on the rear side of the positioning and clamping mechanism; a cutting mechanism is arranged at the upper right position of the passive roller wheel, and a cocoon shell separating mechanism is arranged on the left side of the passive roller wheel; batched and automatic hole cutting can be carried out on the silkworm cocoon of different sizes, silkworm chrysalis and cocoon shells can be separated automatically, the positioning is reliable, the cocoon for egg production can not be crushed or injured due to cutting, the cocoon cutting quality is good, and the efficiency is high.

Description

technical field [0001] The invention belongs to the field of sericulture production machinery, and relates to a sericulture production equipment, in particular to an automatic cocoon cutting machine, which is used for cutting seed cocoons to take out silkworm chrysalis in cocoon shells for silkworm egg production. Background technique [0002] In the production process of silkworm eggs, in order for the female and male moths to mate, it is necessary to first cut the cocoon and take out the silkworm chrysalis to hatch into moths. The method for cutting silkworm cocoons at present mainly contains manual use of long blades or single-sided blades for cutting, and several automatic or semi-automatic cocoon cutting equipment are also arranged. Manual cocoon cutting has problems such as easy hand injury, poor safety, low efficiency, and high labor intensity.

AI Technical Summary

Problems solved by technology

Its disadvantages: sending cocoons still rely on manual insertion into the jig one by one, unskilled operation will affect the speed of cocoon cutting

But the defect is that many sensors are installed in the device, including photoelectric sensors, inclination sensors, etc., and a single-chip microcomputer is required to process the data transmitted by the sensors, and then control the work of each stepping motor and electromagnetic clutch. The structure of the whole machine is complicated, and the cost High, slow response, the front cocoon delivery process still needs manual assistance, the efficiency is not high

But there is a defect: how to prevent the cocoons in the cocoon box from being suspended and achieve uniform feeding, this key link has not been well resolved

However, this device cannot overcome the problem of cocoon silk sticking, that is, it is difficult for multiple cocoons stuck together to fall into the guide cylinder one by one from the hopper
