Description
Technical Field
The invention belongs to the field of silk reeling equipment in silk making engineering, and particularly relates to a fine cylinder hole threading-free end guide device on an automatic silk reeling machine.
Background
Reeling means a process of drawing silk from cocoons. The original reeling process is to dip the cocoons in hot water and to manually draw and wind them on the silk tool to unreel silk. The automatic silk reeling machine is used in most silk producing factory and the technological process includes groping, groping and picking, twisting and twisting sheath, winding and drying of raw silk. The end collecting is to combine end silks of a plurality of positive end cocoons, lead out the end silks through an axle hole of the end connecting device and penetrate through the end collecting device, and the moisture of the silks can be reduced through the end collecting device so as to detect rough silks on the silks.
The commonly used filament guide button, commonly known as porcelain eye, is still a traditional porcelain material, and has a circular appearance with a diameter of about 20 mm, and a cylindrical filament guide button hole with a diameter of about 0.2 mm is arranged in the middle. In the process of reeling silk, a plurality of end silks of the normal end cocoons need to pass through a small hole at the center of an end collector (porcelain eye) together to be combined into a strand silk, but the strand silk is frequently broken to cause the strand silk to be cut off, the strand silk needs to pass through the hole of the end collector again, and the operation is difficult because the hole diameter is very small, particularly for people with certain age and poor eyesight.
The existing threading-free filament guide button holes have a common characteristic that two or three components which are positioned on different planes and provided with local holes are superposed up and down to form closed holes on axial projection. For example: CN104153007B fine hole threading-free filament guide collector published 11/19/2014, which comprises a first master slice and a second master slice stacked on each other, an annular gasket clamped between the first master slice and the second master slice, a cavity with a circular cross section formed between the first master slice and the second master slice, a circular working slice capable of performing reciprocating rotary motion from a position "a" to a position "B" in the cavity, and a guide member for guiding the working slice to perform rotary motion, wherein when the working slice moves to the position "B", a filament guide collecting master hole located on the first master slice, a working slave hole on the working slice, and a filament guide master hole on the second master slice are stacked on each other, and a circular filament guide hole is formed in an axial projection of the working slice, but radial through grooves are formed in each layer of the filament guide hole, so that a column body hole of a conventional filament guide collector cannot be formed.
For another example: CN105951186A, published 2016, 9, 21, discloses a threading-free filament guide button, which comprises a support sheet, a baffle plate hinged to the middle of the sheet body of the support sheet through a central pivot, one end of the support sheet is connected with a filament guide button body, a filament through hole is formed in the end of the filament guide button body, an opening allowing filament guide buttons to enter the filament through hole is formed between the filament through hole and the edge of the end of the filament guide button body, a hook body capable of closing the opening of the filament through hole is connected to one side of the baffle plate, and the hook body of the baffle plate and the filament through hole of the filament guide button body are mutually overlapped to form a circular filament guide button hole.
Due to the fact that a through groove radially exists in a local hole of each component of an existing threading-free thread collector, the holes of the thread collector cannot be like a cylinder hole of a traditional thread collector (porcelain eye), and therefore when silk is reeling, silk threads are detected and prevented from being broken, especially small and rough knots are not achieved, and the effect is not as good as that of a traditional thread collector (porcelain eye), and therefore the quality index of silk cleanliness and cleanliness is affected. Because the existing thread collector has a small hole and is difficult to perforate, or the existing thread collector has a problem of poor detection and rough word prevention effect even though perforation is avoided, so that the existing thread collector cannot be popularized and applied generally, and the requirement of large-scale silk-making industrial production cannot be met.
