When the needle 3 breaks, the broken needle 3 falls on the storage plate 35 and is driven to move toward the first yielding groove 12 by the cooperation of the push plate 11. During the movement, the power supply 21 is pushed by the broken needle 3 to move toward the alarm 28. When the first electrode sheet 23 contacts the second electrode sheet 26, the alarm 28 alarms to remind the operator.

[0062] Embodiment three:

[0063] like Figure 2 As shown, the structure of the automatic sewing lockstitch machine for curtain production and processing disclosed in the third embodiment of the present invention is basically the same as that in the second embodiment, except that:

[0064] A slide groove 32 is provided at the bottom of the push plate 11 at a position corresponding to the power source 21, a matching slider 34 is slidably provided inside the slide groove 32, and a third elastic member 33 is provided between the slider 34 and the inner side wall of the slide groove 32, and the slider 34 is elastically provided inside the slide groove 32 through the third elastic member 33;

[0065] A matching second push plate 31 is fixedly disposed at the inner bottom end of the first receiving groove 7 at a position corresponding to the sliding block 34;

[0066] A storage plate 35 is fixedly connected to the bottom of the slider 34. A second clearance groove 36 is provided on a side wall of the storage plate 35 facing the power source 21. A matching top plate 37 is provided inside the second clearance groove 36 for limited sliding movement.

[0067] A fourth receiving groove 39 is provided inside the slider 34, the fourth receiving groove 39 is communicated with the second giving way groove 36, and a matching fixing rod 40 is slidably provided inside the fourth receiving groove 39, a fourth elastic member 42 is provided between the bottom of the fixing rod 40 and the inner bottom end of the fourth receiving groove 39, the fixing rod 40 is elastically provided inside the fourth receiving groove 39 through the fourth elastic member 42, and a matching fixing groove 38 is provided at the bottom of the push plate 11 at a position corresponding to the fixing rod 40;

[0068] A matching top plate 37 is provided at a side wall of the fixing rod 40 corresponding to the end of the top plate 37;

[0069] A drop hole 43 is formed at the bottom of the countersunk hole 6, and the drop hole 43 penetrates the sewing lockstitch machine body 2;

[0070] When the push plate 11 is pushed out by the guide rod 8, the push plate 11 will drive the elastically arranged storage plate 35 to extend synchronously. At this time, the elastically arranged storage plate 35 is fixedly connected to the push plate 11 under the action of the elastically arranged fixing rod 40. If the needle 3 is broken, the broken needle 3 is pushed into the first clearance groove 12 by the storage plate 35. When the storage plate 35 contacts the side wall of the first clearance groove 12, the sliding second clearance groove 36 is squeezed. At this time, the elastically arranged fixing rod 40 slides out from the fixing groove 38, and the elastically arranged storage plate 35 drives the broken needle 3 to be pushed out from the first clearance groove 12. The first yielding groove 12 shrinks inside, and when it shrinks to the drop hole 43, the storage plate 35 is stored in the sliding groove 32, and the broken needle 3 falls out of the drop hole 43. When the needle 3 connected to the needle and thread rod 5 rises, the elastically set push plate 11 will move to the inside of the first receiving groove 7. During the movement, the elastically set storage plate 35 moves relative to the push plate 11 under the action of the second push plate 31. After moving a certain distance, the elastically set fixing rod 40 will coincide with the fixing groove 38. At this time, under the action of the fixing rod 40 and the fixing groove 38, the storage plate 35 will be fixedly connected to the push plate 11.

[0071] The specific scheme of this invention is as follows: the curtain to be processed is placed under the needle 3, and then the needle and thread rod 5 is controlled by the sewing machine body 2 to drive the needle 3 to move up and down to process the curtain;

[0072] During the processing, the downward movement of the needle 3 will squeeze the elastic push rod 14, and the rotation of the push rod 14 will squeeze the first air bag 15, so that the gas inside the first air bag 15 is discharged to the inside of the second air bag 20 through the exhaust pipe 16. The expansion of the second air bag 20 drives the guide block 19 to move, and then drives the push plate 11 to move, to prevent the push plate 11 from blocking the downward movement of the needle 3. When the needle 3 breaks, the broken needle 3 falls on the storage plate 35. When the needle 3 connected to the needle and thread rod 5 withdraws from the countersunk hole 6, the elastically set push plate 11 and the storage plate 35 drive the broken needle 3 to move toward the first give way groove 12. During the movement, the power supply 21 is pushed by the broken needle 3 to move toward the alarm 28. When the first electrode sheet 23 contacts the second electrode sheet 26, the alarm 28 alarms to remind the operator;

[0073] At the same time, when the storage plate 35 contacts the side wall of the first give way groove 12, the sliding second give way groove 36 is squeezed, and the elastically arranged fixing rod 40 slides out from the fixing groove 38 at this time, and the elastically arranged storage plate 35 drives the broken needle head 3 to shrink from the first give way groove 12. When it shrinks to above the drop hole 43, the storage plate 35 is stored in the slide groove 32, and the broken needle head 3 falls out from the drop hole 43. When the needle head 3 connected to the needle and thread rod 5 rises, the elastically arranged push plate 11 will move to the first receiving groove 7. When moving, the elastically arranged storage plate 35 moves relative to the push plate 11 under the action of the second push plate 31. After moving a certain distance, the elastically arranged fixing rod 40 will overlap with the fixing groove 38. At this time, under the action of the fixing rod 40 and the fixing groove 38, the storage plate 35 will be fixedly connected to the push plate 11.
