[0014] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the preferred embodiments of the present invention are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for the purpose of further illustrating the features and advantages of the present invention, and are not intended to limit the patent claims of the present invention. Based on the examples in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0015] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0016] Example 1

[0017] See also Figures 1 to 3 As shown, the PET bottle cold filling equipment involved in this embodiment includes a body, which is provided with a turntable 1 and a first motor 2 for controlling the rotation of the turntable 1. The side of the turntable 1 is provided with a plurality of conveying troughs 3 distributed in a circular array with equal angles around its axis. A liquid injection mechanism is provided directly above one of the conveying troughs 3, and the liquid injection mechanism includes a liquid storage tank 4 and a liquid injection gun 5. A capping mechanism 100 is provided directly above another conveying trough 3.

[0018] The screw cap mechanism 100 includes a first push rod cylinder 6, which includes a cylinder body 61 and a telescopic arm 62 extending vertically downward. A flexible pressure head 7 is provided at the end of the telescopic arm 62. A second motor 8 is provided on the cylinder body 61, and a driving gear 9 is provided on the output shaft of the second motor 8. The driving gear 9 is engaged with a driven gear 10 rotatably connected to the telescopic arm 62. The thickness of the driven gear 10 is greater than that of the driving gear 9.

[0019] Furthermore, the flexible pressure head 7 is a rubber pressure head.

[0020] Furthermore, the bottom of the flexible pressing head 7 is provided with anti-slip protrusions 71 .

[0021] In this embodiment, the first motor 2 controls the rotation of the turntable 1 to convey the PET bottles placed in the conveyor trough 3. A manual workstation is provided between the liquid injection mechanism and the capping mechanism 100. This workstation is used to manually pre-screw the bottle cap onto the filled PET bottle. The cap is then transported along the turntable 1 to the position directly below the flexible pressure head 7. The telescopic arm 62 extends, and the driven gear 10 slides relative to the driving gear 9 (maintaining a meshed state), causing the flexible pressure head 7 to press against the bottle cap. The second motor 8 is then activated, and the gear transmission causes the flexible pressure head 7 to rotate with the bottle cap, tightening it onto the PET bottle.

[0022] The flexible pressure head 7 is made of rubber material, which has large deformation and friction, so that the tightening is reliable.

[0023] The anti-slip protrusions 71 are added to increase friction and improve the tightening effect.
