DETAILED DESCRIPTION

[0024] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Example 1: Please refer to Figure 1-Figure 6 The present invention provides a technical solution: an energy-saving fully automatic spiral duct machine forming device, comprising: a base plate 1, a material rack 2 is arranged on one side of the upper surface of the base plate 1, the material rack 2 comprises an inner support rod 3, one end of the inner support rod 3 is fixedly connected with an inner support block 4, one side of the inner support block 4 is arranged with a guide cylinder 5, the lower surface of the guide cylinder 5 is fixedly connected with a guide block 6, one side of the guide block 6 is rotatably connected with a fixed block 7, the other side of the guide block 6 is fixedly connected with a threaded sleeve 8, one side of the threaded sleeve 8 is arranged with an adjusting rod 9, the bottom of the adjusting rod 9 is rotatably sleeved in a slider 10, one side of the slider 10 is rotatably connected with an upper guide roller 11, a limiting block 12 is arranged on the upper side of the upper guide roller 11, and a lower guide roller 30 is arranged on the lower side of the upper guide roller 11.

[0026] The bottom plate 1 is used to fix and support each component. The material rack 2 is used to place the material roll. The inner support rod 3 is pushed outward to drive the inner support block 4 to move outward, so that the inner support block 4 abuts against the innermost ring surface of the material roll, thereby fixing the material roll on the outer ring surface of the inner support block 4. The inner support block 4 is then indirectly driven to rotate by a large motor arranged on one side of the material rack 2, so as to feed the material. The large threaded rod 27 is rotated to drive the threaded sleeve 8 thereon to move, and the threaded sleeve 8 thereby pushes the guide block 6 to move. Since the bottom of the guide block 6 is rotatably connected to the fixed block 7, the guide block 6 will rotate under the limit of the fixed block 7 to achieve the purpose of adjusting the guide. The purpose of the inclination angle of the cylinder 5 is to guide the raw material plate during feeding, thereby avoiding collision and damage with the subsequent traction guide device. When it is necessary to process strip steel of different thicknesses, the adjusting rod 9 is rotated, and the adjusting rod 9 is threadedly connected to the limit block 12, so that the adjusting rod 9 can drive the slider 10 mounted on the bottom thereof to move, so that the slider 10 drives the upper guide roller 11 away from or close to the lower guide roller 30, thereby adjusting the distance between the upper guide roller 11 and the lower guide roller 30, and then being able to adjust the position of strip steel of different thicknesses, thereby improving the practicability of the entire feeding traction guide device.

[0027] Embodiment 2: Based on Embodiment 1, one end of the inner support rod 3 is fixedly connected to the inner support block 4.

By sleeveing ​​the inner ring of the material roll on the outer wall of the inner support block 4, a positioning hole is provided on the side of the rotating disk 19 close to the hand wheel. By twisting the hand wheel to drive the long shaft 18 to rotate, the long shaft 18 thereby drives the large gear 17 fixedly sleeved thereon to rotate, and the large gear 17 thereby meshes with the small gear 16 around it for transmission, and the short shaft 15 is driven to rotate under the rotation of the small gear 16, and the short shaft 15 thereby drives one end of the connecting rod 14 to rotate. The other end of the connecting rod 14 is slidably connected to the sliding rod 13 through the sliding groove provided thereon, thereby driving the inner support rod 3 to move. The inner support rod 3 moves outward under the limit of the rotating disk 19 until the inner support block 4 is tightly fitted into the inner ring surface of the material roll, thereby fixing the material roll, and then a small threaded rod is sleeved in the limiting hole provided on the handwheel and the positioning hole provided on one side of the rotating disk 19, so that one end of the small threaded rod is threadedly connected to the positioning hole, thereby fixing the handwheel, thereby ensuring the stability of the material roll fixation, and the insertion position of the small threaded rod depends on the specific situation. At this time, by starting the large motor, the large motor drives the support disk 21 to rotate, and the support disk 21 drives the rotating disk 19 to rotate under the connection of the connecting column 20, so that the rotating disk 19 indirectly drives the inner support block 4 to rotate, and then the inner support block 4 drives the material roll to rotate, thereby feeding.
