Description
Technical Field
The invention relates to the technical field of glove processing equipment, in particular to a thread end trimming device of a glove serging machine.
Background
Knitted gloves are generally finished with a cuff of the glove being stitched and a rubber band being wrapped inside for ease of use, for aesthetic and durability. At present, the most common method is to adopt a special glove overlocking machine, and manually operate one machine to complete the overlocking of the glove bowl opening, namely, manually place the glove bowl opening below a presser foot of the overlocking machine, and then start a motor through a pedal plate; in the process, an operator not only needs to operate the motor to drive the serging machine to work so as to rotate for multiple circles to complete the whole serging of the wrist part of the glove, but also needs to manually cut off a lockstitch line and trim the line head after the serging is completed, the whole process is very complicated, hands and feet are needed to be used together to keep coordination, and meanwhile, attention is required to be focused to ensure that lockstitch joints are overlapped, so that the work requires a certain skill of a worker, and only the worker engaging with more skilled technology can reluctantly improve a certain working efficiency due to the fixed rotating speed of the machine. Recently, an automatic glove overlocking machine appears on the market, and the working process of the automatic glove overlocking machine is as follows: the glove is sleeved below a presser foot of a machine head of the serging machine, a motor is started to complete serging, a glove grabbing device acts to take down the glove, a thread trimming device acts to dial a serging thread to a thread trimming position, and a thread trimming device acts to cut off the thread trimming thread. However, the design of each device is too complex, the power source of the thread trimming device is linked with the motor, and the thread trimming device always performs thread trimming when the motor is started to perform edge trimming, so that the normal edge trimming line on the glove is very easy to be trimmed, the edge trimming line is disconnected, the wrist opening of the glove is loosened, the waste of the glove is excessive, and the production cost is increased. On the other hand, the thread trimming device which always runs during the overlocking has a very short service life due to long running time. In order to solve the problem that the trimming device trims the overlock line, an enterprise designs that an elastic sheet is arranged at the position of the trimming line of the trimming device and abuts against the wrist opening of the glove, so that the distance between the overlock line and the position of the trimming line is lengthened, but the line head left on the glove after trimming is longer, and the attractiveness and the quality of the glove are seriously influenced.
