Description

Technical Field

[0001] This utility model relates to the field of capping technology, specifically a capping mechanism for a salt soda bottle. Background Technology

[0002] During the production of salt soda bottles, the bottle caps need to be pressed down to seal the bottle opening. Generally, the bottle caps are first placed on the salt soda bottle in sequence, and then the pressure cylinder is rotated to install the bottle caps on the salt soda bottle.

[0003] The bottle cap may tilt during placement, and during the subsequent pressing and rotating of the pressure cylinder, the bottle cap may get stuck at the bottle opening, preventing the bottle cap from being installed correctly. Therefore, a capping mechanism is needed that can first straighten the bottle cap during the installation process. Utility Model Content

A drive motor 3 for driving the lower pressing component to rotate is provided on one side of the adjusting plate 2. The lower pressing component includes a pressure cylinder 4 and a piston component disposed on the upper end of the pressure cylinder 4. A plurality of clamping blocks 41 are arranged in a ring at the lower end of the pressure cylinder 4. The clamping blocks 41 are slidably installed in the corresponding sliding grooves of the pressure cylinder 4, and the clamping blocks 41 are provided with clamping plates 42 for clamping and fixing the bottle cap inside the pressure cylinder 4. The piston component is rotatably connected to the clamping blocks 41 through a pull rod 43 to control the synchronous extension and retraction of the clamping blocks 41, thereby clamping the bottle cap.

[0028] Specifically, clamping blocks 41 are arranged in a ring at the lower end of the pressure cylinder 4. A clamping plate 42 is integrally formed on the inner side of the clamping blocks 41. A piston controls the telescopic movement of the clamping blocks 41 to hold the bottle cap via the clamping plate 42. During the clamping process, the clamping plate 42 can first straighten the bottle cap, positioning it directly above the bottle opening for accurate capping later. The telescopic movement of the clamping plate 42 can accommodate bottle caps of different sizes, improving versatility.

[0029] In this embodiment, limiting blocks 44 are provided on both sides of the lower end slide groove of the pressure cylinder 4, and limiting slots 45 are provided on both sides of the clamping block 41 corresponding to the limiting blocks 44, so as to improve the stability of the extension and retraction movement of the clamping block 41; the clamping plate 42 extends out of the lower end of the pressure cylinder 4 so as to clamp the bottle cap, and the clamping plate 42 is an arc-shaped plate structure.

[0030] In this embodiment, the piston component includes an air cylinder 5 fixedly installed on the upper end of the pressure cylinder 4. A piston rod 51 is slidably provided inside the air cylinder 5. A piston block 52 is provided at the upper end of the piston rod 51. A pull plate 53 is connected to the lower end of the piston rod 51. Several pull rods 43 are arranged in a ring at the lower end of the pull plate 53 corresponding to the clamping block 41. One side of the pull rod 43 is rotatably connected to the pull plate 53, and the other side is rotatably connected to the clamping block 41. The piston rod 51 pulls the clamping block 41 to extend and retract through the pull rods 43.

[0031] The upper end of the air cylinder 5 is provided with an air guide pipe 54 that communicates with the inner cavity of the air cylinder 5. The upper end of the air guide pipe 54 is connected to the outer end air supply pipe through a rotary joint 55. The adjusting plate 2 is provided with a bracket plate 56 that fixes the rotary joint 55.

[0032] The air cylinder 5 is equipped with a spring 57 that pushes the piston block 52 to move. One end of the spring 57 abuts against the inner wall of the air cylinder 5, and the other end abuts against the piston block 52, thereby pushing the piston block 52 down and accelerating the unfolding of the clamping block 41.

[0033] In this embodiment, a drive gear 31 is installed at the outer end of the output shaft of the drive motor 3, and a driven gear 32 is provided at the upper end of the pressure cylinder 4, which is connected to the drive gear 31 for transmission, so as to control the rotation of the lower pressure component.

The two sides of the adjusting plate 2 are abutted against the upper and lower ends of the air cylinder 5 through end face bearings 21 to drive the lowering component to move up and down. The air cylinder 5 is connected to the rotary joint 55 through the air guide pipe 54. After the double-stroke cylinder 11 controls the cylinder 4 to descend to the appropriate position, it draws air into the air cylinder 5 through the air guide pipe 54 to generate negative pressure. The piston block 52 drives the pull plate 53 to rise through the stopper rod 51. The pull rod 43 pulls the clamping block 41 to move inward to the inside of the cylinder 4 so as to use the distributed clamping plates 42 to clamp and fix the bottle cap. During the clamping process, the bottle cap will be automatically straightened. The double-stroke cylinder 11 controls the adjusting plate 2 to press down. During the pressing process, the drive motor 3 drives the cylinder 4 to rotate, so that the bottle cap is rotated and installed on the salt soda bottle.
