Abstract
The present invention relates to an opener device for an inner drum of an embroidery hook, which comprises a main shaft and a hook shaft perpendicular to the main shaft, wherein a hook is provided at the head end of the hook shaft, a hook gear is provided at the end of the hook shaft, Wherein the spindle is provided with a spindle gear and a hook gear, the spindle gear and the hook gear meshing with each other to rotate the hook shaft and the hook, and an opener drive shaft is provided parallel to one side of the hook shaft, And an opener driving cam for driving the motor to move along the axial direction, wherein the opener driving shaft is movably installed in an opener driving shaft sleeve, and an opener restoring spring is installed between the opener driving shaft sleeve and the opener driving shaft And the inner drum is interlocked with the head end of the opener drive shaft so as to be rotatable in the clockwise direction The opener will be handed installation. According to the present invention, since the inner drum is rotated in the clockwise direction by the opener grip, the pressure between the outer drum and the inner drum of the hook is reduced, and when the upper thread comes out between the inner drum and the hook stopper, Can be prevented from being worn.
Description
The present invention relates to a kind of embroidery machine.
1, the
It is an object of the present invention to provide an opener device for an inner drum of an embroidery hook which prevents pressure from being generated between a stationary inner drum and a rotating outer drum, .
In order to achieve the above object, an opener device of an inner drum of an embroidery hook of the present invention includes a main shaft and a hook shaft perpendicular to the main shaft, a hook is provided at a head end of the hook shaft, Wherein the main shaft is provided with a main shaft gear and a hook gear, and the main shaft gear and the hook gear are engaged with each other to rotate the hook shaft and the hook. Wherein an opener drive shaft is provided in parallel to one side of the hook shaft and the main shaft is provided with an opener drive cam for driving the opener drive shaft to move along the axial direction and the opener drive shaft is movable in an opener drive shaft sleeve An opener return spring is provided between the opener drive shaft sleeve and the opener drive shaft, and an opener grip is provided at the head end of the opener drive shaft for interlocking the inner drum to be rotatable in a clockwise direction.
Preferably, the opener grip is installed in an opener block, and the opener block is provided with a hooping structure connected to a head end of the opener drive shaft.
Preferably, the opener grip includes an opener head facing the hook, and the opener head is formed with an opener slant surface for rotating the inner hook.
Preferably, the opener grip includes an opener plate, the opener plate is L-shaped, one side of the opener plate is fixed to the opener block, and the opener head is fixed to the other end of the opener plate Respectively.
Preferably, a bearing or a roller that matches the outer circumferential surface of the opener drive cam is provided at the free end of the opener drive shaft.
In working the hook and the face according to the present invention, the main shaft drives the opener drive shaft to linearly move along the axial direction by the opener drive cam. When the upper thread begins to rotate halfway around the inner drum, the opener grip provided at the head end of the opener drive shaft interlocks the inner drum to rotate clockwise so that the pressure between the outer drum and the inner drum can be reduced, When you exit between the drum and hook stopper, you can prevent the upper thread from being cut or scratched.
Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings and examples.
