The work principle of the cloth thickness induction detection device of the sewing machine is as follows:
the cloth 18 enters the detection device through the space between the lower end face of the upper pressing wheel 1 and the upper end face of the lower pressing wheel 3, when the cloth 18 enters, the upper pressing wheel 1 and the lower pressing wheel 3 rotate in different directions respectively, so that the cloth 18 is smoothly brought into the detection device, and the cloth 18 is arranged between the lower end face of the upper pressing wheel 1 and the upper end face of the lower pressing wheel 3 for detection. Go up pinch roller 1 and pinch roller 3 and rotate according to the equidirectional not respectively, can produce same power toward the front, this power is along under 1 terminal surface of last pinch roller and 3 contact surface tangents between the up end of pinch roller toward the forward direction, when cloth 18 is close to above-mentioned contact surface on the faller, thereby can be made cloth 18 enter into under 1 terminal surface of last pinch roller and between 3 up end of pinch roller through the forward power drive that produces very easily, cloth 18 gets into detection device very smoothly and conveniently. When cloth 18 enters between the lower end face of an upper pinch roller 1 and the upper end face of a lower pinch roller 3, a lower pinch roller mounting seat 4 is fixed below a needle plate and cannot move up and down, so that the cloth 18 jacks the upper pinch roller mounting seat 2 through the upper pinch roller 1 to enable the upper pinch roller mounting seat 2 to ascend, a driving rod 5 drives an eccentric wheel 7 to rotate through a rotating shaft three 6, a vertical distance signal of the ascending of the upper pinch roller mounting seat 2 is converted into a deflection angle or a rotating radian signal of the eccentric wheel 7, the eccentric wheel 7 rotates to drive a large gear 9 to rotate through a rotating shaft two 8, the diameter of the large gear 9 is larger than the inner diameter of an eccentric road (the large gear 9 also has a certain degree of signal amplification and a radian with the same rotating angle), the large gear 9 rotates a small gear 10, the diameter of a magnetic steel fixing plate 12 is larger than the diameter of the small gear 10 (the structure also has a certain degree of signal, therefore, the magnet 13 rotates and deviates relative to the hall element 15, the surrounding magnetic field changes, and the voltage signal collected by the hall element 15 also changes. The voltage signal is fed back to the sewing machine for electric control, and each different voltage corresponds to the deviation degree of different Hall elements 15 and magnets 13, namely the rotation angle of the large gear 9 and the small gear 10, the ascending distance of the upper pinch roller mounting seat 2 and the thickness of the cloth 18 in a one-to-one correspondence relationship. Therefore, the thickness of the cloth 18 can be converted by the electric control according to the voltage signal fed back by the Hall element 15, and the rotating speed, the needle pitch and the output torque of the sewing machine are controlled and adjusted according to the detected thicknesses of different cloth 18, so that the sewing smoothness and quality are ensured.
Example two
The structure difference between this embodiment and the first embodiment is as follows: without the structure of the eccentric wheel 7, the driving rod 5 is directly connected with the large gear 9 through the rotating shaft III 6, and the step surface 51 of the driving rod 5 is directly connected with the end surface of the large gear 9 in surface-to-surface contact. Under the condition that the installation position allows, the mode structure of this embodiment is simpler, and is with low costs and installation also more convenient, and other structures are the same with embodiment one, and no longer repeated. In the embodiment, the large gear 9 and the small gear 10 can be separated from each other and are not in contact with each other, and are connected through a gear belt.
The working principle of the present embodiment is different from that of the first embodiment in that: after the upper pinch roller mounting seat 2 rises, the driving rod 5 directly drives the large gear 9 to rotate through the third rotating shaft 6. Other principles are the same as those of the first embodiment, and are not described again.
EXAMPLE III
The structure difference between this embodiment and the first embodiment is as follows: in the embodiment, structures such as the lower pressing wheel 3, the lower pressing wheel mounting seat 4, the second rotating shaft 41 and an opening on a needle plate in the first embodiment are omitted, the upper pressing wheel 1 is directly positioned on the needle plate of the sewing machine table 17, and the lower end face of the upper pressing wheel 1 is directly in contact connection with the needle plate. Other structures are the same as those of the first embodiment, and are not described herein again.
The method of the present embodiment is different from the first embodiment in the following principle: after entering into this detection device between upper pinch roller 1 lower extreme face and the faller as cloth 18, because upper pinch roller 1 can be around the axis of rotation 21 pivoted on the upper pinch roller mount pad 2, upper pinch roller 1 rotates and can produce the power of the terminal surface tangent line forward direction under upper pinch roller 1, when cloth 18 entered into smoothly under the effect of this power entering down pinch roller 3 and the faller between the two. Other methods and principles are the same as those of the first embodiment, and are not described herein again.
