All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-4, a self-adjusting needle device for fabric sewing in a factory assembly line comprises a shell 1, a hollow channel 2 is formed in the shell 1, a telescopic rod 3 is connected to the surface of the hollow channel 2 in a sliding manner, a needle 4 is fixedly connected to the lower end of the telescopic rod 3, pressing plates 17 are fixedly connected to the bottom of the shell 1 and located on two sides of the needle 4, and the pressing plates 17 are in a shape that one end is tilted; through the power of acting on reset spring 10 surface indirectly according to syringe needle 4, and then when control was placed platform 6 and is removed, screw rod 7 also can be promoted by magnetic force and slide in the inside of placing platform 6, because gyro wheel 8 at this moment is in the rotating condition, so gyro wheel 8 can drive burr wheel 9 and remove, burr wheel 9 removes can with make up the surface fabric contact, and when making up the surface fabric when thinner, the appeal between magnetic sheet and electro-magnet 12 is great, so burr wheel 9 is less with the area of making up the surface fabric contact, otherwise area of contact is great, so reached and avoided the effect that the surface fabric burr appears according to making up surface fabric control pay-off dynamics.
The magnet 5 is fixedly connected to the bottom wall of the interior of the shell 1, the placing table 6 is fixedly connected to the bottom of the shell 1, and the plate where the electromagnet 12 is located and the placing table 6 are not of an integral structure, so that the electromagnet 12 can control the placing table 6 to move; the fabric to be sewn is placed on the surface of the placing table 6, the driving part is started to enable the telescopic rod 3 to reciprocate up and down in the hollow channel 2, the telescopic rod 3 can drive the needle head 4 to be in contact with the sewn fabric when moving up and down, if the sewn fabric is thin, the force of the needle head 4 on the surface of the reset spring 10 is large when the needle head 4 is in contact with the textile fabric, the force of the reset spring 10 on the surface of the piezoelectric plate 11 is large when the reset spring 10 is extruded, and the force can be known according to the characteristics of the piezoelectric material; a crystalline material which develops a voltage between two end faces when subjected to a compressive force; in 1880, french physicists p. curie and j. curie brothers found that placing a heavy object on a quartz crystal, some of the surface of the crystal generated a charge, which was proportional to the pressure. This phenomenon is called the piezoelectric effect. Then, the curie brother finds the inverse piezoelectric effect, namely, the piezoelectric body can generate deformation under the action of the external electric field. The mechanism of the piezoelectric effect is: the crystal with piezoelectricity has low symmetry, when the crystal is deformed under the action of an external force, the relative displacement of positive and negative ions in a unit cell ensures that the centers of the positive and negative charges are not superposed any more, so that the crystal is subjected to macroscopic polarization, and the surface charge density of the crystal is equal to the projection of the polarization strength in the surface normal direction, so that opposite charges can appear on two end surfaces when the piezoelectric material is deformed under the action of the pressure. Conversely, when a piezoelectric material is polarized in an electric field, the material deforms due to the displacement of the charge center.
When the pressure on the surface of the piezoelectric plate 11 is larger, the voltage on the surface becomes larger, and in addition, the piezoelectric plate 11 and the conductive tube 13 are in a passage, so that more current flows into the conductive tube 13, namely, the magnetism of the electromagnet 12 becomes stronger, the electromagnet 12 becomes stronger to attract the magnetic plate to move downwards, namely, the distance between the placing table 6 and the shell 1 becomes longer, so that the depth of the needle head 4 acting on the surface of the textile fabric is shortened, otherwise, the needle head becomes longer, and therefore, the effect of utilizing the piezoelectric material to realize the self-adaption of the sewing depth and the sewing fabric is achieved.

When the sewing machine is used, the fabric to be sewn is placed on the surface of the placing table 6, then the driving part is started to enable the telescopic rod 3 to reciprocate up and down in the hollow channel 2, the telescopic rod 3 can drive the needle head 4 to be contacted with the sewn fabric when moving up and down, if the sewn fabric is thinner, the force acting on the surface of the return spring 10 when the needle head 4 is contacted with the textile fabric is larger, the force acting on the surface of the piezoelectric plate 11 when the return spring 10 is extruded is also larger, according to the characteristics of the piezoelectric material, when the pressure on the surface of the piezoelectric plate 11 is larger, the voltage on the surface of the piezoelectric plate is larger, the piezoelectric plate 11 and the conductive pipe 13 are in a passage way, so that the current flowing into the conductive pipe 13 is larger, namely the magnetism of the electromagnet 12 is stronger, the magnetism of the electromagnet 12 can attract the magnetic plate to move downwards, namely the distance between the placing table 6 and the shell 1 is farther, and the depth of the needle head 4 acting on the surface of the textile, otherwise, the length is increased, thereby achieving the effect of utilizing the piezoelectric material to realize the self-adaption of the sewing depth and the sewing fabric.
Through the power of acting on reset spring 10 surface indirectly according to syringe needle 4, and then when control was placed platform 6 and is removed, screw rod 7 also can be promoted by magnetic force and slide in the inside of placing platform 6, because gyro wheel 8 at this moment is in the rotating condition, so gyro wheel 8 can drive burr wheel 9 and remove, burr wheel 9 removes can with make up the surface fabric contact, and when making up the surface fabric when thinner, the appeal between magnetic sheet and electro-magnet 12 is great, so burr wheel 9 is less with the area of making up the surface fabric contact, otherwise area of contact is great, so reached and avoided the effect that the surface fabric burr appears according to making up surface fabric control pay-off dynamics.
