Description
Technical Field
The utility model relates to the technical field of drawing frames, in particular to a compact type broken bar self-detector for a drawing frame.
Background
The drawing frame has the functions of improving the internal structure of the sliver, improving the uniformity of long fragments, reducing the weight unevenness, enabling fibers in the sliver to be straightened and parallel, reducing hooks, enabling fineness to meet the specification, enabling raw materials with different types or different qualities to be uniformly mixed, and achieving the specified mixing ratio. Drawing frames are divided into two main types of roller drawing frames and gilling machines according to the form of drawing mechanisms. The working mode of the roller drawing frame is to combine a plurality of raw material tops and draw the raw material tops, in the drawing process, because the quality and the materials of the raw material tops are different, the situation that individual tops are broken easily occurs, if workers cannot find the raw material tops in time, the produced tops become waste materials which are not in line with the requirements, the raw material waste is serious, the infrared detection group receives infrared signals reflected by the reflecting plate when the cotton tops are not broken, and then the state of the cotton tops is judged, but when the number of the cotton tops is large, the self-detector needs to be designed to be more compact in order to save space occupation, the cotton tops are closer, but the distance between adjacent reflecting plates is also closer, and therefore the infrared rays reflected by the reflecting plates influence the adjacent infrared detection groups, and the detection accuracy is influenced.
Disclosure of Invention
The utility model aims to solve the technical defects and provides a compact broken bar self-detector for a drawing frame, which can be designed more compactly and reduce space occupation.
The utility model discloses a compact broken bar self-checking device used on a drawing frame, which comprises a first support, wherein a supporting rod is horizontally erected on the first support, partition columns are arranged on the supporting rod at equal intervals, a cotton sliver passes through the space between the two partition columns through the upper part of the supporting rod, a second support is arranged on the yarn outlet side of the first support, a rotating shaft is horizontally erected on the second support, the rotating shaft is higher than the supporting rod, a plurality of shaft sleeves are rotatably and uniformly distributed on the rotating shaft, each shaft sleeve is positioned between two adjacent partition columns, a pressing plate extending along the radial direction of the shaft sleeve is arranged on the shaft sleeve, the free end of the pressing plate is smoothly abutted against the cotton sliver after being turned downwards, a light shielding plate is arranged on one side, far away from the pressing plate, of the shaft sleeve, the plane of the light shielding plate is perpendicular to the rotating shaft, a laser generator is arranged on the second support above one end of the rotating shaft, a laser receiver is arranged on the second support above the other end of the rotating shaft, and the laser generator emits laser light which is received by the laser receiver, and the laser receiver is electrically connected with a controller of the drawing frame.
When drawing is carried out, the cotton sliver passes through the space between the two separation columns from the upper part of the supporting rod, when the cotton sliver is not broken, the cotton sliver turns up the pressing plate belt, and at the moment, the light shielding plate on the shaft sleeve does not shield the laser, so that the cotton sliver is judged to be in an unbroken state. When the cotton sliver breaks, the cotton sliver does not support the pressing plate, the pressing plate drops immediately, the light shielding plate rotates upwards to block laser, the laser receiver cannot receive the laser, the drawing frame controller immediately judges that the cotton sliver is broken, drawing is stopped at the same time, and as the plane of the light shielding plate is perpendicular to the rotating shaft, the adjacent shaft sleeves can be designed to be very compact, the laser is shielded through the light shielding plate, and even if the design between the adjacent shaft sleeves is very compact, whether the cotton sliver breaks can be accurately detected.
In order to remind workers when the cotton sliver is disconnected, a controller of the drawing frame is electrically connected with a buzzer.
The beneficial effects of the utility model are as follows: the utility model can be designed more compactly when the number of cotton slivers is larger, reduces space occupation, and does not influence detection accuracy.
