The silk feeding mechanism is responsible for separating the iron wire from the coil and feeding it to the silk plate. The function of the silk plate is to coil the iron wire for bundling reinforcing steel bars. The silk winding mechanism is responsible for tightening the iron wire to achieve stable bundling of reinforcing steel bars. In this process, the design of the silk plate is crucial because it directly affects the efficiency of the iron wire and the quality of the bundling.

The coiling column 23 is partially exposed in the wire guide groove 21, so that when the wire is conveyed to the front end of the wire guide groove 21 of the wire outlet plate 2 by the wire feeding mechanism 3, the wire touches the coiling column 23 to guide the bending and coiling, the hardness of the coiling column 23 is greater than that of the wire outlet plate 2, as an optional scheme, the coiling column 23 is a tungsten steel column, which has the advantages of high density, high hardness, impact toughness, wear resistance and the like, and has a longer service life as the coiling column 23.
[0027] Compared with the existing wire outlet assembly assembled by multiple components, the present scheme adopts the integrally formed wire outlet plate 2, which not only enhances the structural strength of the wire outlet plate 2, but also improves the accuracy of the product, which is helpful to simplify the processing and assembly process, in addition, it also enhances the smoothness of the iron wire flowing in the wire guide groove 21 of the wire outlet plate 2, effectively prevents the blockage and deformation of the iron wire in the wire outlet block of the bundling machine, at the same time, the coiling column 23 with higher hardness is installed at the front end of the wire guide groove 21, which is helpful to guide the iron wire to be outlet in an arc shape and form a coil, prolonging the service life of the wire outlet plate 2.
[0028] As an optional scheme, referring to Figure 4 The arc edge of the coiling column 23 at least partially extends into the wire guide groove 21, so that when the iron wire is conveyed forward by the wire feeding mechanism 3 to touch the coiling column 23, the coiling column 23 with the protruding arc surface has a better guiding coiling effect on the iron wire, and the contact surface area of the iron wire with the coiling column 23 is larger, prolonging the service life of the coiling column 23 and further improving the coiling smoothness.
