Detailed ways

The present invention will be described in further detail below in conjunction with the examples and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

As shown in Figures 1 to 6, the present invention provides a double-sided upper shaft wire feeder, including a frame 1, several pay-off shafts 2 arranged on the frame 1, a shaft center 3, several guide wheels 4 and Several tension adjustment mechanisms 5, both ends of the pay-off shaft 2 are fixed on the axis 3 through the top 6, the axis 3 is connected with the tension adjustment mechanism 5, and the pay-off shaft 2 and the tension adjustment mechanism 5 correspond one by one, several A guide wheel 4 is arranged on the frame 1. The top 6 positioned at the outside can be disassembled to facilitate the replacement, installation and maintenance of the pay-off shaft 2.

Wherein, as shown in Figure 6, the tension adjustment mechanism 5 includes a tension hand wheel 51, a tension spring 52, a tension disc 53, a tension friction plate 54, a bearing 55, a bearing seat 56, a tension shaft 57, a tension belt 58 and a tension pulley 59 , one end of the tension spring 52 is connected with the tension hand wheel 51, the other end of the tension spring 52 is connected with one side of the tension disc 53, and the tension spring 52 is wrapped around the tension shaft 57, and the other side of the tension disc 53 rubs against the tension One side of the sheet 54 contacts, the tension disk 53 is fixed on the tension shaft 57, and the other side of the tension friction sheet 54 is fixed on the bearing seat 56, the bearing seat 56 is fixed on the bearing 55, and the bearing 55 is installed on the tension shaft 57 , the tension pulley 59 is installed on the tension shaft 57, and the tension pulley 59 and the shaft center 3 are connected by a tension belt 58, and the bearing 55 is arranged between the bearing block 56 and the tension pulley 59.

During use, turning the tension handwheel 51 can adjust the pressure between the tension spring 52 and the tension disk 53, and the pressure is converted into a friction force between the tension disk 53 and the tension friction plate 54, and the friction force is further transmitted to the tension shaft 57 Then, it is transmitted to the tension pulley 59 through the tension shaft 57, and further transmitted to the axis 3 through the tension belt 58, which becomes a resistance to prevent the wire 9 from being in a slack state due to the random rotation of the pay-off shaft 2 and disturbing the normal discharge. line order.

The wire rack also includes a tension gun 7, the inside of the tension gun 7 is provided with an adjustment extension spring, and the end of the adjustment extension spring is provided with a torx head screw 8, and the tension gun 7 also includes a guide wheel 4.
