When the pushing plate 11 pushes the pressing nozzle 12, the lubricating oil in the oil storage tank 2 is transported to the sponge pad 3 through the delivery pipe 6 connected to the pressing nozzle 12. The end of the delivery pipe 6 is a smoothly set spherical shape. The suture of the quilting machine fits with the sponge pad 3, thereby lubricating the suture, reducing the friction when the suture moves, and effectively preventing the suture from breaking.

[0032] Embodiment 2:

[0033] This embodiment is used to solve the problem that it is difficult to evenly replenish the sponge pad 3 with oil.

[0034] See also Figure 1 , Figure 5 As shown, a thread-breaking prevention mechanism of a computer quilting machine of the present embodiment includes a cover plate 17 fixedly connected to the back of an installation box 1 and cooperating with an installation cavity 18, the cover plate 17 is penetrated by and fixedly connected with a motor 10, a gear 2 9 is plugged into the output end of the motor 10, the gear 2 9 is meshed with the gear 1 8, and the gear 2 9 is fixedly connected to the rotating shaft 2 16.

[0035] Start the motor 10, the motor 10 drives the gear 2 9 to rotate, and through the gear 2 9, drives the gear 1 8 meshing with it. Through the rotation of the gear 1 8, the sponge pad 3 can be automatically replenished with oil. At the same time, when the gear 2 9 rotates, the rotating shaft 2 16 fixedly connected to it can be rotated. When the rotating shaft 2 16 rotates, the sponge pad 3 fixedly connected to it rotates. When the sponge pad 3 rotates, it can cooperate with the delivery pipe 6 to evenly apply the lubricating oil to the sponge pad 3 so that it evenly absorbs the lubricating oil.

[0036] Combining Embodiment 1 with Embodiment 2
