In this embodiment, the magnet 127 is disposed on the back surface of the fixing plate 121, and attracts the sliding member 125.
A sliding rail assembly is arranged between the fixed plate 121 and the sliding frame 122; a guide groove 1240 and a guide post 1241 for positioning and installing the clamping wheel 124 are arranged between the sliding frame 122 and the corresponding end of the clamping wheel 124, and the corresponding end of the clamping wheel 124 can be arranged in a sliding and rotating way by matching the guide post 1241 with the guide groove 1240; the sliding direction of the guide groove 1240 is vertical to the sliding direction of the sliding frame 122; the guide groove 1240 is arranged on the sliding frame 122; the guide posts 1241 are disposed at respective ends of the pinch rollers 124.
The at least one pair of clamping wheels 124 are symmetrically arranged, and the symmetrically arranged clamping wheels 124 can keep the ball guide rod 1 stably positioned. The pinch roller 124 is an eccentric wheel or a cam. The part of the clamping wheel 124, which is at least matched with the ball guide rod 1, is arc-shaped or wheel-shaped. That is, the clamping wheel 124 may also be a deformed simple clamping wheel, for example, the matching position of the clamping wheel and the ball guide rod 1 is a smooth arc or wheel, and other parts not matching with the ball guide rod 1 may be set to any other shapes.
The sliding frame 122 is provided with a rack or a strip-shaped gear 129, the first driver 123 is a driving motor or a power input shaft, and the driving motor or the power input shaft is provided with a gear 128 matched with the rack or the strip-shaped gear 129. In this embodiment, the first driver 123 is a driving motor disposed on the second fixing frame 107.
The sliding rack 122 is a U-shaped sliding rack 122, and the fixing plate 121, the clamping roller 124 and the sliding member 125 are disposed in a U-shaped groove of the U-shaped sliding rack 122.
The embroidery machine also comprises a controller for controlling and coordinating all the drives, such as all the motors and cylinders, wherein the controller can be independently arranged or can adopt a controller of the embroidery machine.
