[0026] As Figures 1-4As shown, the utility model provides a technical scheme: a rolling device, including movable rod 1, sleeve 2 and support base 3, support base 3 is placed in bottle body placing carousel 10 one side, still be provided with inner plug placing device and bottle cap placing device (not shown in the drawing) in bottle body placing carousel 10 side, movable rod 1 and sleeve 2 between the movable plug-in, sleeve 2 and support base 3 are fixed through the fixed frame, make movable rod 1 and sleeve 2 keep with support base 3 perpendicular, the bottom of movable rod 1 that penetrates support base 3 is provided with driving part one 4, movable rod 1 is driven along the axis direction of sleeve 2 and moves up and down reciprocating through driving part one 4.

[0027] The top of movable rod 1 is provided with cross block 5, and the one side of cross block 5 is rotatably connected with rotating shaft 6, the bottom of rotating shaft 6 is fixed with chuck 7, chuck 7 can be electric or pneumatic, for clamping the outside of bottle cap, the other side of cross block 5 is provided with driving part two 8, and rotating shaft 6 is driven to rotate through driving part two 8, chuck 7 and driving part two 8 are prior art, which will not be described in detail in the present scheme.

[0028] As shown in Figure 2 and Figure 3 Driving part one 4 includes movable shaft 401 and motor 402, movable shaft 401 is movably connected with the bottom of support base 3, motor 402 is fixed on the bottom of support base 3, the output end of motor 402 is fixed with the end of movable shaft 401, and motor 402 is started. When the motor 402 rotates, the movable shaft 401 is driven to rotate, the disc 403 is fixed on the shaft body of the movable shaft 401, and the convex groove 404 is formed on the side of the disc 403 facing the movable rod 1, the support roller 405 is arranged at the bottom of the movable shaft 401, and the support roller 405 is matched with the convex groove 404. In order to reduce the friction between the support roller 405 and the side surface of the convex groove 404, reduce the working noise and improve the service life of the support roller 405, the support roller 405 is movably connected between the movable rod 1.

[0029] When the motor 402 is started, the disc 403 is driven to rotate. Since the support roller 405 is located in the convex groove 404, and the movable rod 1 and the sleeve 2 are perpendicular to the support base 3, the disc 403 is driven to rotate, and the movable rod 1 is driven to move up and down reciprocating.

[0030] As shown in Figure 3 and Figure 4 The top of movable rod 1 is provided with height adjusting mechanism, the height of cross block 5 is adjusted through height adjusting mechanism, so that the height of chuck 7 is adjusted, so as to adapt to the bottle body of different height.

[0031] Specifically, as shown in Figure 4As shown, the height adjustment mechanism includes a threaded rod set at the top of the movable rod 1, a cross block 5 movably inserted into the threaded rod, a support threaded tube 901 movably screwed onto the rod body, the cross block 5 placed on the top surface of the support threaded tube 901, a guide assembly and a positioning assembly set at the top of the threaded rod, the cross block 5 moves along the axial direction of the threaded rod under the guidance of the guide assembly, the height of the cross block 5 is adjusted, and the cross block 5 is fixed by the positioning assembly.

[0032] The guide assembly includes a top plate 902 fixed to the top of the threaded rod. Several telescopic rods 907 are provided between the top plate 902 and the cross block 5. Each telescopic rod 907 consists of two rods that are inserted into each other.

[0033] In addition, the positioning component includes a circular groove 903 formed on the horizontal block 5 and a vertical groove formed on the threaded rod. The threaded rod has several slots 904. The circular groove 903 and the vertical groove are connected through the slots 904. A screw 906 is movably connected in the vertical groove. A handwheel is fixed at the top of the screw 906 to facilitate the rotation of the screw 906. A screw plate is movably screwed onto the body of the screw 906. Several positioning plates 905 are formed on the outer side of the screw plate, equal in number to the number of slots 904. One side of the positioning plate 905 extends into the circular groove 903. In this solution, the number of slots 904 is set to three, and correspondingly, the number of positioning plates 905 is also set to three. The width of the circular groove 903 is 1-3 times the width of the slot 904, and the thickness of the positioning plate 905 is 0.1-0.3 times the width of the slot 904.

[0034] As a supplement to this solution, when adjusting the height of clamp 7, such as Figure 4 As shown, the upward adjustment is explained. First, rotate the screw 906. When the screw 906 rotates, it drives the positioning plate 905 to move upward. When the positioning plate 905 moves to the middle position of the slot 904, stop rotating the screw 906 and lift the horizontal block 5 to the appropriate position. Then rotate the support threaded tube 901 until the top surface of the support threaded tube 901 contacts the bottom surface of the horizontal block 5. Rotate the screw 906 in the opposite direction. The positioning plate 905 moves downward along the screw 906 until the positioning plate 905 is pressed against the bottom wall of the circular groove 903, thus completing the fixation of the horizontal block 5.

[0035] During operation, motor 402 is started, and its rotation drives disc 403 to rotate. Since support roller 405 is located within groove 404, and movable rod 1 and sleeve 2 are perpendicular to support base 3, the rotation of disc 403 drives movable rod 1 to move up and down reciprocally (when disc 403 is located as shown in the image). Figure 4When the disc 403 rotates 180 degrees, the movable rod 1 is located at the lowest position, it can be known that when the chuck 7 moves downward, the clamping jaws of the chuck 7 are in a loosened state, and when the bottle cap is located between the clamping jaws of the chuck 7, the clamping jaws of the chuck 7 and the bottle cap are in a gripped state, at this time, the rotation of the chuck 7 to the bottle cap is realized by driving the driving member two 8 to drive the rotating shaft 6 to rotate.

[0036] Although the embodiments of the present application have been shown and described, it should be understood by those ordinary skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended embodiments and their equivalents.
