The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0021] See also Figure 1 As shown, in this embodiment, a wire drawing cavity dispensing machine is provided, including a bracket 1, and a groove 2 extending along the length direction is arranged on the upper part of the bracket 1. Preferably, the groove wall of the groove 2 is arc-shaped, and the groove 2 is used to place an inner layer tube, such as a sheath tube.

[0022] A moving component is provided at the upper end of the groove 2, and the moving component is used to drive the glue dispensing mechanism 5 to move, and the glue dispensing mechanism 5 is used to dispense glue and bond the wire drawing cavity to the inner layer tube placed in the groove 2.

[0023] In this embodiment, the moving component includes a slide rail 3 and a slider 4. The slide rail 3 is installed at the upper end of the bracket 1. The slider 4 is movably connected to the slide rail 3. The slider 4 is used to install the glue dispensing mechanism 5. When in use, the glue dispensing mechanism 5 is manually pushed to make the slider 4 move along the slide rail 3, glue is dispensed on the surface of the inner tube, and then the wire drawing cavity is pressed at the glue dispensing location to achieve bonding between the wire drawing cavity and the inner tube.

[0024] In another embodiment, the moving component may also be a linear screw module, which drives the dispensing mechanism 5 to move, thereby improving the efficiency of production and processing.

[0025] See also Figure 2-4 As shown, the glue dispensing mechanism 5 includes a glue dispensing bracket 51, which is fixedly connected to the slider 4. A cylinder 52 is installed on the upper end of the glue dispensing bracket 51, and the cylinder 52 is connected to the lifting bracket 53. A crimping roller 54 is installed on the lifting bracket 53. The crimping roller 54 is installed on the lifting bracket 53 through a first support shaft 57. A reel 55 is arranged on one side of the crimping roller 54.
