Detailed implementation mode

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-4 , an embodiment provided by the present invention: An automatic capping device includes a support device 3. Second control devices 2 are rotatably installed at the front and rear ends of the support device 3. A first control device 1 is fixedly installed at the top of the second control device 2. The first control device 1 includes a connecting block 4, a hydraulic cylinder 5, a roller 6, an upper bracket 7, a lower bracket 8 and a guide rod 9. The lower bracket 8 is slidably sleeved on the guide rod 9. The guide rods 9 are equidistantly and fixedly installed at the bottom end of the upper bracket 7. The rollers 6 are equidistantly rotatably installed on the inner sides of the upper bracket 7 and the lower bracket 8. The upper bracket 7 is fixedly installed on the connecting block 4. The connecting block 4 is fixedly installed at the top end of the hydraulic cylinder 5.

[0021] The second control device 2 includes a support frame 10, a threaded rod 11 and an L-shaped sliding rod 12. The threaded rod 11 is threadedly inserted into the center of the front end of the L-shaped sliding rod 12. The support frame 10 is fixedly installed at the top end of the L-shaped sliding rod 12. The support device 3 includes a guide groove 13, a support base 14, a transmission substrate 15 and a capping machine 16. The transmission substrate 15 is fixedly installed at the top end of the support base 14. The capping machine 16 is fixedly installed at the top end of the support base 14, and the transmission substrate 15 is located below the capping machine 16. The guide grooves 13 are equidistantly opened at the front and rear ends of the support base 14. Since the specification size of the L-shaped sliding rod 12 is the same as the internal size of the guide groove 13, the phenomenon that the L-shaped sliding rod 12 is skewed can be prevented.

[0022] The hydraulic cylinder 5 is fixedly installed at the top end of the support frame 10. The threaded rod 11 threadedly penetrates through the L-shaped sliding rod 12 and is rotatably installed at the front and rear ends of the support base 14, which can support the L-shaped sliding rod 12 to perform the work of adjusting the distance.

[0023] A plastic sleeve is fixedly installed on the surface of the roller 6 to prevent the roller 6 from rubbing excessively against the bottle.

[0024] The L-shaped sliding rod 12 is slidably inserted inside the guide groove 13 to keep the L-shaped sliding rod 12 moving in a straight line.

[0025] A threaded hole adapted to the threaded rod 11 is provided inside the front end of the L-shaped sliding rod 12. When the threaded rod 11 is screwed, it will drive the L-shaped sliding rod 12 to move.

[0026] Working principle: When in use, when it is necessary to transfer bottles of different heights, the hydraulic cylinder 5 can be started to drive the connecting block 4 to move upward. The upper bracket 7 is fixedly installed at the front end of the connecting block 4, and the bottom end of the lower bracket 8 slides on the transfer substrate 15, so as to prevent the lower bracket 8 from falling. At the same time, when the hydraulic cylinder 5 is started, it will drive the upper bracket 7 to move upward, so as to protect bottles of different heights. When the upper bracket 7 moves, it slides inside the lower bracket 8 through the guide rod 9, so as to ensure that the upper bracket 7 moves up and down in a straight line and prevent the upper bracket 7 from tilting. At the same time, the rollers 6 are equidistantly rotatably installed on the inner sides of the upper bracket 7 and the lower bracket 8, so as to improve the smoothness when the bottle passes through the upper bracket 7 and the lower bracket 8. At the same time, a plastic sleeve is fixedly installed on the surface of the roller 6, so as to prevent the roller 6 from rubbing excessively against the bottle, and complete the work of restricting bottles of different heights. When it is necessary to transfer bottles of different diameters, the threaded rod 11 can be rotated. Since a threaded hole adapted to the threaded rod 11 is provided at the front end of the L-shaped sliding rod 12, and the threaded rod 11 is threadedly inserted through the L-shaped sliding rod 12 and rotatably installed at the front and rear ends of the support base 14, when the threaded rod 11 rotates, it will drive the L-shaped sliding rod 12 to move into the support base 14, thereby adjusting the distance between the rollers 6 and facilitating the transfer work of bottles of different diameters. During the movement of the L-shaped sliding rod 12, since the L-shaped sliding rod 12 slides inside the guide groove 13, it can ensure that the L-shaped sliding rod 12 moves in a straight line and prevent the L-shaped sliding rod 12 from falling, and complete the work of restricting bottles of different diameters. When this device is in use, when the hydraulic cylinder 5 is started, it drives the distance between the upper bracket 7 and the lower bracket 8 to be adjusted, so as to prevent the bottles of different heights from tilting or toppling during transmission. At the same time, by screwing the threaded rod 11 to drive the L-shaped sliding rod 12 to move, the distance between the rollers 6 can be adjusted, so as to restrict the transmission of bottles of different diameters on the transfer substrate 15 and complete the work.

[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
