The utility model provides a kind of double motor sewing machine, including shell, lower motor is installed in the lower end inside shell back, the motor shaft front end of lower motor is connected with pinion, motor shaft sleeve is set on motor shaft, pinion and the large gear on the cloth feeding main shaft are mutually engaged, the drive gear is connected in the front end of cloth feeding main shaft, and the upper cloth feeding wheel is installed in drive gear by universal shaft connection;The drive gear on the cloth feeding main shaft and lower gear are mutually engaged, and lower gear is fixedly connected in the rear end of lower cloth feeding shaft, and lower cloth feeding gear is installed in the front end of lower cloth feeding shaft connection.The utility model, by setting the transmission structure that lower motor drives pinion and the large gear of cloth feeding main shaft engages, cooperate drive gear and universal shaft connection upper cloth feeding wheel, lower gear linkage lower cloth feeding shaft and lower cloth feeding gear, make upper and lower cloth feeding wheel rotate at the same speed, form the synchronous driving force of clamping cloth, realize parallel synchronous feeding, avoid cloth skew or wrinkle, improve sewing precision.

The application discloses a display panel and a display device. The first metal layer is arranged on the substrate and comprises a first signal transmission part; the insulating layer covers the substrate and the first metal layer, and comprises a protruding part covering the first signal transmission part; the second metal layer is arranged on the side of the insulating layer away from the first metal layer and comprises a second signal transmission part, and the second signal transmission part covers at least part of the side wall of the protruding part; the protruding part comprises a first sub-layer and a second sub-layer, and a first opening is arranged at the side wall, the first sub-layer is located on the side of the second sub-layer away from the first signal transmission part, the second signal transmission part extends into the first opening and is in contact with the second sub-layer, and the adhesion between the second sub-layer and the second signal transmission part is greater than the adhesion between the first sub-layer and the second signal transmission part. The application can reduce the probability of disconnection of the second signal transmission part at the climbing position, and improve the yield of the display panel.

The utility model provides a kind of embroidery machine independent presser foot machine head, it is related to embroidery equipment technical field, including shell, the inside installation of shell has presser foot drive crank, the side of presser foot drive crank is connected with needle bar drive crank, the rear end of shell is connected with presser foot bottom dead point, the bottom of shell is connected with presser foot driver, the outside of presser foot driver is connected with cushion block.In the utility model, needle bar, presser foot, thread picking sewing three big mechanisms are independently operated, each mechanism uses a cam to drive, a total of three cams are used, the stress of each component is greatly reduced, and the durability of the parts can be guaranteed during high-speed operation. The needle bar module, presser foot module and thread picking module operate independently and are not related to each other. The driving of the three is not associated, but only related in time. This makes the sewing state more stable. It can reduce the thread breakage rate and improve the quality of embroidery products.
