Detailed Description

The invention will be further described with reference to the accompanying drawings and the detailed description below:

as shown in fig. 1 to 5, fig. 1 to 5 disclose an embodiment of a core feeding mechanism, which comprises a mounting base plate 1, a core feeding sliding plate 2 is arranged on the mounting base plate 1, and the core feeding sliding plate 2 can reciprocate on the mounting base plate 1 along an X-axis. In this embodiment, specifically, the core feeding sliding plate is implemented by a guide rail and sliding block structure, a first guide rail 21 (or a first sliding block) is arranged at the bottom of the core feeding sliding plate 2, and a first sliding block 22 (or a first guide rail) corresponding to the first guide rail 21 (or the first sliding block) is arranged on the installation bottom plate 1. Of course, besides, the reciprocating movement of the core-feeding sliding plate 2 on the installation base plate 1 along the X-axis can also be realized by a dovetail groove guide rail structure or a T-shaped guide rail structure, which is not described in detail herein. In the invention, a mandrel component 3 is arranged at one end of a core feeding sliding plate 2, a cam 52 is arranged at the other end of the core feeding sliding plate 2, a track groove 51 is arranged on the cam 52, the cam 52 is connected with the core feeding sliding plate 2 through a roller 20, one end of the roller 20 is fixed on the core feeding sliding plate 2, and the other end of the roller 20 penetrates into the track groove 51 and can slide in the track groove 51; in this embodiment, specifically, the cam 52 is driven by the power source 6 and can reciprocate on the core feeding sliding plate 2 along the Y axis, in this embodiment, a bending swing arm 10 is further disposed on the mounting base plate 1, a through groove is disposed in the bending swing arm 10, and the power source 6 drives the cam 52 to slide in and out of the through groove of the bending swing arm 10. In the present invention, the cam 52 reciprocates along the Y-axis by a rail-slider structure or a linear bearing structure. In this embodiment, specifically, the reverse slider structure is implemented, a second guide rail 521 (or a second slider) is disposed on one side of the cam 52, and a second slider 522 (or a second guide rail) corresponding to the second guide rail 521 (or the second slider) is disposed on the mounting base plate 1. When the core-feeding sliding plate 2 is used, when the power source 6 drives the cam 52 to reciprocate on the core-feeding sliding plate 2 along the Y axis, the core-feeding sliding plate 2 reciprocates along the X axis, so that the core feeding or core pulling of the mandrel assembly 3 on the core-feeding sliding plate 2 is realized.
