The traditional PET bottle conveying device includes: a number of bottle conveying units, each of which includes: a turntable, a number of bottle clamps are arranged at intervals around the turntable, the turntable is supported on a movable support and driven by a servo motor, the clamping centers of all bottle clamps on the turntable are located on the same pitch circle, the structure of each bottle clamp includes: a base, a bottle clamping assembly is arranged on the base, the bottle clamping assembly includes: a pair of clips, each clip has a clamping end and a connecting end at both ends, each clip is hinged to the base, a notch is formed between the outer ends of the clamping ends of the two clips for the bottle to enter or escape, and the clamping end of each clip A clamping portion for clamping the bottle mouth is formed on the inner side of the housing; a compression spring is provided between the connecting ends of the two clips, and a blocking component is provided on the outer sides of the connecting ends of the two clips. The blocking components are fixed to the base. Under the action of the compression spring, the connecting ends of the pair of clips are elastically blocked against the outer blocking components, which puts the pair of clamping portions in a clamping state that is close to each other and can clamp the bottle mouth; when the elastic force of the compression spring is overcome, the clamping ends of the pair of clips can be rotated outward to enlarge the gap, thereby allowing the bottle mouth to pass through the gap and enter between the pair of clamping portions or disengage from the pair of clamping portions. The bottle clamps in two adjacent bottle conveying units are installed with a certain height difference. The clamping portions of the bottle clamps in the two adjacent bottle conveying units are clamped at the bottom and top of the support plate of the bottle mouth, respectively, so that the bottle is transferred at the tangent position of the pitch circles of the two bottle transfer units.

[0003] The above-mentioned PET bottle conveying device has the following defects: during the rotation of the turntable, the bottles clamped by the bottle clamps are easily skewed under the action of centripetal force, making it impossible to ensure that the bottles always remain in a vertical downward position during the rotation. This makes it easy for the bottles to fall, be squeezed, or have their bottle mouths scratched during the handover process, thereby affecting production efficiency and product packaging quality.

The bottle clamp assembly comprises a pair of clips 11, each having a clamping end 12 and a connecting end 13 at either end. Each clip 11 is hingedly connected to the base 1. A notch 14 is formed between the outer ends of the clamping ends 12 of the two clips 11, allowing bottles to enter or exit. Each clip 11 has a clamping portion 121 formed on the inner side of the clamping end 12 for clamping the bottle mouth. A driving mechanism is disposed at the connecting end of the two clips 11, which can drive the pair of clamping portions 121 to maintain a position capable of clamping the bottle mouth, or to return the pair of clamping portions 121 to a position capable of clamping the bottle mouth after opening. In this embodiment, the driving mechanism comprises a compression spring 15 disposed between the connecting ends 13 of the two clips 11, and a blocking component is disposed on the outer side of each connecting end 13 of the two clips 11. The blocking components are fixed to the base 1. In this embodiment, the blocking components are a pair of blocking posts 16 disposed on the base 1. Under the action of the compression spring 15, the connecting ends 13 of the pair of clips 11 elastically abut against the outer retaining posts 16, causing the pair of clamping portions 121 to move inward and clamp the bottle mouth. When the bottle mouth overcomes the elastic force of the compression spring 15, the clamping ends 12 of the pair of clips 11 can rotate outward, widening the notch 14, thereby allowing the bottle mouth to pass through the notch 14 and enter between the pair of clamping portions 121 or disengage from the pair of clamping portions 121. Specifically, the connection structure between the compression spring 15 and the connecting ends 13 of the pair of clips 11 includes: outwardly protruding retaining protrusions 131 are respectively provided on the inner sides of the connecting ends 13 of the pair of clips 11, and the two ends of the compression spring 15 are sleeved over the pair of retaining protrusions 131.

[0023] A block 17 is provided above or below the pair of clips 11 to protect the outer wall of the bottle mouth. In order to reduce the weight of the block 17, a through hole 171 is provided on the block 17. The outer end of the block 17 is provided with an arc-shaped stop surface 172 that can fit against the outer wall of the bottle mouth. The stop surface 172 is located above or below the position opposite to the notch 14. Figure 1 As shown, when the stopper 17 is located above the clip 11, the clip 11 is used to clamp the bottom of the bottle mouth support plate, and the stopper surface 172 of the stopper 17 is used to stop the top of the bottle mouth support plate. Figure 2 As shown, when the stopper 17 is located below the clip 11, the clip 11 is used to clamp the top of the support plate of the bottle mouth, and the stopping surface 172 of the stopper 17 is used to stop the bottom of the support plate of the bottle mouth.

[0024] The installation structure of the two clips 11 and the stopper 17 includes: two studs 18 are provided on the base 1, and the two clips 11 are movably set on the two studs 18 through flange bearings 19. The stopper 17 is provided with two mounting holes, and the two mounting holes are respectively installed on the two studs 18. A wear-resistant washer 20 is provided on the stud 18 between the clip 11 and the stopper 17.

In each of two adjacent bottle transfer units, the block in the bottle clamp of one bottle transfer unit is above the clamping piece, and the block in the bottle clamp of the other bottle transfer unit is located below the clamping piece. The following is a detailed description of the arrangement of two bottle transfer units.

First bottle clamps 5 are arranged on the turntable of the first bottle transfer unit 100, and second bottle clamps 6 are arranged on the turntable of the second bottle transfer unit 200. Figure 7 As shown, in this embodiment, the first stopper 51 in the first bottle clamp 5 is located above the first clamping piece 52 , and the second stopper 61 in the second bottle clamp 6 is located below the second clamping piece 62 .

[0026] During the rotation of the first bottle transfer unit 100, the first stopper 51 of the first bottle clamp 5 is against the outer wall of the bottle mouth above the bottle mouth support plate. During the rotation of the second bottle transfer unit 200, the second stopper 61 of the second bottle clamp 6 is against the outer wall of the bottle mouth above the bottle mouth support plate. The arrangement of the first stopper 51 and the second stopper 61 ensures that the bottle can always remain in a vertical downward position during the rotation. Figure 7 As shown, when the first bottle clamp 5 and the second bottle clamp 6 are handed over, the first clamping piece 52 of the first bottle clamp 5 is clamped on the top of the support ring on the bottle mouth, and the first stopper 51 of the first bottle clamp 5 is blocked against the bottom of the support ring on the bottle mouth, and the second clamping piece 62 of the second bottle clamp 6 is clamped on the bottom of the support ring of the bottle mouth, and the second stopper 61 of the second bottle clamp 6 is blocked against the top of the support ring of the bottle mouth, forming an all-round clamping guard around the bottle mouth, which can effectively ensure that the bottle remains in a vertical downward state during the handover, thereby avoiding the phenomenon of bottle falling, scratching the bottle mouth, and bottle squeezing during the transfer, thereby effectively improving the bottle conveying efficiency and effectively improving the filling production quality.
