Description
[ field of technology ]
The invention relates to clothing machinery, in particular to an integrated control device for broken needle protection of a jujube beating machine.
[ background Art ]
In the clothing industry, including the production and manufacturing process of female bras, jujube beating is an indispensable sewing link, and the jujube beating sewing process is very high-speed, such as the sewing process has problems, such as: the broken needle and broken thread can not be stopped immediately, which directly leads to the broken nitre of the needle point and broken needle bar section part and splashed everywhere after the accidental broken needle in the high-speed sewing process. Some broken needle bars fly to the clothes beside and in the bra being manufactured, some fly to the ground and even some fly to the clothes of a sewing machine, so that the finding is very difficult, and sometimes, a plurality of people are often required to find the needle points after the broken needles and other broken parts of the needles in a large area for a long time. The customer of the company requires that the broken parts of all broken needles must be found and recorded for the first time after the needle breakage in the sewing process, if the broken parts of all broken needles are not found, the customer must go through a strict needle checking procedure before packaging, and the requirements of the customer are particularly strict.
Since broken needles and their fragmented parts splash when broken, and workers usually stare at the needles, they often have to wear protective tools to protect their faces, particularly their eyes.
Generally, after cutting off the needle thread, the thread end part is randomly positioned below the needle, and when the presser foot is pressed down, the thread end is pressed by the presser foot with high probability, thereby leading the needle thread to be tightened and being positioned on the needle 1 When the machine is started to work, the machine needle is easy to break. In the existing jujube beating vehicle, a poking rod is arranged to poke the thread end to one side after a needle is lifted, so that the thread end is poked to one side. In this way, the probability of pressing the wire by the presser foot is greatly reduced, but the wire is automatically dropped back under the action of dead weight, and the pressing of the wire by the presser foot still happens frequently.
In addition, the thread ends of the jujube-playing vehicle with or without the deflector rod are in random states, the thread ends are always in a sewing area and sewn between the sewing threads during sewing, and after sewing is finished, the thread ends are usually required to be picked out from the sewing threads and then cut off, so that the thread ends are troublesome to process.
In order to prevent or reduce broken needles of the jujube beating machine, the broken needle points and other broken parts of the needles are required to be searched manually for a large area for a long time, and research and development improvement is carried out aiming at the design defect that the existing jujube beating machine does not have broken needle protection devices.
