[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0024] The utility model embodiment discloses a filling head height adjustment mechanism of a filling machine.
[0025] Reference Figure 1-3 , a filling head height adjustment mechanism of a filling machine, comprising a bottom plate 1 and a top plate 3, the top plate 3 is arranged on the upper side of the bottom plate 1, vertical rods 2 are fixedly arranged on both sides of the upper surface of the bottom plate 1, the upper ends of the two vertical rods 2 are fixedly connected to the top plate 3, a screw rod 8 is rotatably arranged between the middle parts of the bottom plate 1 and the top plate 3, a slide plate 5 is threadedly sleeved on the rod wall of the screw rod 8, a plurality of clamping blocks 6 are fixedly arranged on the front side of the slide plate 5, a filling head 7 is fixedly installed inside the plurality of clamping blocks 6, and the plurality of filling heads 7 are threadedly locked to the inner side of the clamping blocks 6 by bolt threads, so as to facilitate the disassembly and maintenance of the filling heads 7, and sliders 4 are fixedly arranged on both ends of the rear side of the slide plate 5, and the two sliders 4 are movably sleeved with the corresponding vertical rods 2, so that the slide plate 5 can slide stably;
[0026] Reference Figure 1-3 A rotating wheel 9 is fixedly sleeved on the top of the screw rod 8, a square shell 10 is fixedly provided on the upper surface of one side of the rotating wheel 9, a block 11 is slidably provided inside the square shell 10, a sliding rod 12 is fixedly sleeved inside the block 11, and both ends of the sliding rod 12 extend to the outside of the square shell 10.
[0027] Reference Figure 1-3 A limiting mechanism for limiting the rotation of the screw rod 8 is arranged between the upper surface of the top plate 3 and the lower end of the sliding rod 12. The limiting mechanism includes a gear 13 and an outer gear ring 14. The outer gear ring 14 is movably sleeved on the upper end of the screw rod 8. The lower side of the outer gear ring 14 is fixedly connected to the top plate 3. The outer gear ring 14 is concentrically arranged with the screw rod 8. The gear 13 is fixedly sleeved on the lower end of the sliding rod 12. The gear 13 is meshed with the outer gear ring 14. A spring 15 is movably sleeved on the upper end of the vertical rod 2. The lower end of the spring 15 is fixedly connected to the upper surface of the block 11.
