Embodiment 1

[0053] Such as Figures 1 to 8 As shown, the first embodiment provides the first embodiment of the sewing material thickness modular detection device of the present invention.

[0054]The sewing material thickness modular detection device in the first embodiment includes: a supporting body 1, a movable body 2 and a detection mechanism. The support body 1 and the sewing machine body are separate parts, and the support body 1 has a mounting portion 11, which is used for detachable connection with the sewing machine body, so that the support body 1 can be quickly disassembled on the sewing machine body. A closed accommodating space is formed inside the supporting body 1 . The movable body 2 is movably arranged in the accommodation space of the supporting body 1, and the accommodation space of the supporting body 1 is provided with an opening for the movable body 2 to protrude from, and one end of the movable body 2 extends out of the accommodation space of the supporting body 1 ...

Embodiment 2

[0069] Such as Figures 9 to 11 As shown, the second embodiment provides the second embodiment of the sewing material thickness modular detection device of the present invention.

[0070] Embodiment 2 is basically the same as Embodiment 1, and the similarities will not be repeated. The difference lies in that the function of the clamping fit between the stopper 16 and the upper end of the stopper groove 21 is the same as that of the stopper 3 and the presser foot. 9. The abutment of the upper surface plays the same role. Only one of the stopper 16 and the stopper 3 can reach the lowest position to which the movable body 2 can move downwards, so that the detection device can match the sewing machine as a whole. The purpose of lifting and lowering the presser foot 9 of the main body is synchronous action. Therefore, the second embodiment adopts the method that the elastic member 7 elastically presses between the lower end of the limiting groove 21 and the limiting part 16, that ...

Embodiment 3

[0075] Such as Figures 12 to 16 As shown, the third embodiment provides the third embodiment of the sewing material thickness modular detection device of the present invention.

[0076] Embodiment 3 is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that in this embodiment 3, the thickness of the sewing material changes so that the movement mode of the movable body 2 is to swing back and forth, and the movable body 2 can be relatively The supporting body 1 is arranged in the accommodation space to swing back and forth. In this way, the movement of one end of the movable body 2 protruding from the accommodation space of the supporting body 1 at the opening of the accommodation space for the movable body 2 to protrude is to swing back and forth at the opening, so refer to Figure 12 , Figure 13 with Figure 16 , the opening should consider the swing range of the movable body 2, and expand the opening range appropriately along...

Abstract

The invention relates to the technical field of sewing machines, in particular to a sewing material thickness modular detection device and a sewing machine comprising the sewing material thickness modular detection device. The sewing material thickness modular detection device includes: a support body, the support body and the sewing machine body are separate parts independent of each other and has a mounting part for detachable connection with the sewing machine body, and a closed accommodation space is formed inside the support body; A body, which can be movably arranged in the accommodation space, one end of the movable body extends out of the accommodation space and is located above the sewing material, when the thickness of the sewing material changes, the movable body moves through the contact between the sewing material and the movable body; and detection The mechanism is arranged in the accommodation space, and is used for detecting the movement range of the movable body and sending the detection information to the control module of the sewing machine body. Both the movable body and the detection mechanism are arranged in the accommodating space of the supporting body to form an independent modular device and form a closed overall structure with good dust-proof effect and convenient disassembly and assembly.

Description

technical field [0001] The invention relates to the technical field of sewing machines, in particular to a sewing material thickness modular detection device and a sewing machine comprising the sewing material thickness modular detection device. Background technique [0002] The sewing machine is equipped with a sewing material thickness detection device, which is used to identify changes in the thickness of the sewing material (such as thickening of the sewing material, thinning of the sewing material, and over-stem of the sewing material) during the sewing process, so that the control system of the sewing machine can detect the thickness of the sewing material. Adjust the sewing speed accordingly. [0003] The existing sewing material thickness detection device has complex structure, high cost, and is exposed to the outside. It is inevitable that the detection element will be stuck and malfunction due to the pollution of thread wool and cloth scraps. Contents of the inve...
