Problems solved by technology

[0004] The volume of this pedal structure is relatively large (length 100mm×width 100mm×thickness 50mm or more), and the stability and precision need to be further improved; in mass production, the magnetization intensity of each magnet is different, and the Hall magnet is very sensitive to the distance. , the magnet induction process is easily disturbed

Embodiment Construction

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0025] see Figure 1-4 , an integrated inductance pedal for an industrial sewing machine, including a sleeve-shaped pedal housing 5, the outer surface of the pedal housing 5 is provided with external threads, and the inductance 14 (inductance coil) is threadedly connected with the pedal housing 5 to facilitate adjustment The position of the inductor 14 on the pedal housing. The upper and lower ends of the inductance 14 are respectively provided with inductance limit nuts (7, 8) which play a position-limiting role to limit the position of the adjusted inductance 14. During production testing, the inductance limit nuts (7, 8) move the inductance to find the theoretical inductance value at the zero position.

Abstract

The invention discloses an integrated inductor pedal for an industrial sewing machine. The integrated inductor pedal comprises a sleeve shaped pedal shell, wherein the exterior of the pedal shell is sleeved with an inductor; one end of the pedal shell is provided with a pedal cover; a step shaped inner hole is arranged in the pedal shell; an iron core which is slidable up and down along the innerhole and is used for interacting with the inductor is arranged in the inner hole of the pedal shell; a running spring is arranged between the iron core and the pedal shell; and one end of the iron core stretches out from the other end of the pedal shell to be connected with a joint, and an elastic jacking device is arranged between the other end of the iron core and the pedal cover. The integrated inductor pedal for the industrial sewing machine has the advantages of higher stability and precision, small interference, smaller volume and little occupation space.

Description

technical field [0001] The invention relates to the technical field of industrial sewing machines, in particular to a pedal structure of an industrial sewing machine. Background technique [0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing material. [0003] The principle of the pedal structure of existing industrial sewing machines is mainly based on magnet induction: (1) when the rocker is rotated, the magnetic field is changed by Hall induction, and the amount of change of the magnetic field has a linear relationship with the rotation angle of the rotating shaft. Various states of the pedals can be known. (2) The light sensor is housed in the pedal, and the rotating shaft is forwarded to the corresponding position, and the light is blocked, and the sensor sends a signal. When working, it is divided into three gears, and it is zero when standing s...
