Abstract: A yarn feeder may comprise a winding wheel, a driving member, at least a locating member, and a plurality of tension pieces. The winding wheel has a first end and a second end, and a plurality of locating holes are formed on the winding wheel adjacent to the first end. The driving member has a ring coupled with the second end of the winding wheel, and the ring comprises at least a driving rod extended along an outer surface of the winding wheel from the second end to the first end, and an end of the driving rod close to the first end which comprises a driving portion and a connecting portion thereon. The locating member comprises a shell, a pivot shaft, a first column, and a locating column. The tension pieces are respectively connected between the ring of the driving member and the first end of the winding wheel.

Abstract: A yarn feeder may comprise a metric-sized motor and a winding wheel, and a drive shaft axially protruding from a first end of the motor is configured to connect to a rotating member. The winding wheel formed in a tube shape comprises a first end and a second end, and an interior channel is adapted to axially penetrate through the winding wheel from the first end to the second end thereof. The interior channel is configured to accommodate the motor, and the rotating member is coupled with the interior channel such that the motor is configured to drive the winding wheel through the rotating member. The motor in the present invention is a metric-sized motor which is not only easy to buy in the market but also reduces manufacturing cost and the volume of the yarn feeder.

Abstract: A sensing apparatus for yarn feeder may comprise a yarn feeder and a tension controller. The tension controller has an elongated sensing block installed therein, and a horizontal extending board is connected to the sensing block. An operating rod is mounted on a middle upper surface of the extending board at one end and upwardly sticks out of the tension controller to pivotally connect to a tension pulley at the other end. A yarn wound on a winding wheel of the yarn feeder is configured to couple with the tension pulley. At least an impedance sensing piece is attached on a surface of the sensing block, and a deformable hole horizontally penetrates through the sensing block. When the sensing block is pressed or pulled, the tension controller can obtain the tension value of the yarn and further calculate the torsion value of the yarn feeder.

Abstract: A food storage cabinet may comprise a main body, an inert gas cylinder, a vacuum unit and a storage container. The main body has a controller which is electrically connected to a motor, and the motor further comprises a spindle connected to a measuring rod to achieve dropping stored food to a scale. The scale is also electrically connected to the controller such that when the preset amount of stored food on the scale is met, the controller is configured to automatically stop the motor. The inert gas cylinder and the vacuum unit are used for maintaining the inner space of the storage container in vacuum and filled with inert gas respectively, thereby keeping the stored food fresh. Also, an operating unit is installed adjacent to the measuring rod of the storage container to drive the measuring rod for dropping stored food manually.

Abstract: A yarn feeder may comprise a driver and a winding wheel. The driver has a front cover, a rear cover, a stator disc and a rotor disc, and the front cover and the rear cover are configured to fit together to form a housing therebetween which accommodates the stator disc and the rotor disc therein. The stator disc has a first through hole, and a plurality of teeth are formed around the first through hole to enable a couple of coils to be wound thereon. The rotor disc has a connecting hole, and a plurality of magnetic members are formed around the connecting hole. A connecting base extended from a first end of the winding wheel is engaged with the connecting hole, and the driver is connected to a tension controller to detect the tension of yarn and further to control the rotational speed of the driver.
