Problems solved by technology

[0005] However, in the automatic bobbin thread changing device of the existing computerized embroidery machine, the bobbin transmission mechanism mostly adopts the design of pushing a small pulley along the running guide rail (this mode is also adopted in the applicant's invention patent ZL 201310552496.9), and some other designs use Compressed air is used as push drive (see Chinese invention patent ZL 201310303545.5), etc. These design structures are relatively complicated, and it is difficult to realize the miniaturization of the bobbin thread changing device, so it is not convenient to reduce the installation space of the bobbin thread changing device and increase the machine capacity of a single embroidery machine. Head count
[0006] In another case, because the bobbin thread changing device of the embroidery machine is still in the popularization process, different embroidery machine models produced by equipment manufacturers will have different configuration requirements for the bobbin thread changing device (some The machine is not equipped with a bobbin thread changing device); in addition, some computerized embroidery machine users need to install an automatic bobbin thread changing device on the purchased equipment

Abstract

The invention provides a separated type multifunctional bottom thread replacing device of an embroidering machine. The separated type multifunctional bottom thread replacing device is composed of a base plate connection angle, a mounting base plate, a pulley, a pulley motor, a shuttle row, an oil injection pump, an oil storage box, an oil nozzle and an independent controller, wherein a pulley wheel guide groove is formed in the mounting base plate; the pulley is in sliding connection with a pulley guide platform through a pulley guide rod; the rear side face of the pulley is connected with a rotary shaft of a guide pulley wheel through a bearing; the pulley motor is in sliding connection with the guide pulley wheel through a transmission fork plate driven by a belt; the shuttle row does linear movement along a shuttle row guide rod; the shuttle row is provided with a shuttle core and a hollow shuttle core storage position; the oil nozzle is arranged in front of a rotary shuttle; and the oil nozzle is controlled by a rotary shuttle automatic oil spraying system. The device is of a separated and small-sized independent structure controlled by the independent controller, and the computer embroidering machine can realize automatic bottom thread replacement and maintenance of the rotary shuttle, so that the production efficiency and the automatic degree of computer embroidering are improved.

Description

technical field [0001] The invention relates to the technical field of bobbin thread changing in computerized embroidery, in particular to a bobbin thread changing device for a discrete multifunctional embroidery machine. Background technique [0002] The automatic bobbin thread changing device greatly reduces the labor intensity of the embroidery production process and shortens the shut-down and shuttle changing time, and significantly improves the production efficiency, so it is gradually widely used on computerized embroidery machines. [0003] At present, for computerized embroidery machines with the function of automatic bobbin thread changing, the bobbin thread changing devices are all designed as an integral part of the embroidery machine: the whole machine is under centralized control and unified drive, and even some parts of the device corresponding to each machine head are also designed. connected. This is undoubtedly reasonable for the arrangement of the control,...
