[0032] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0033] like Figure 1-11As shown, a filling transfer clamping mechanism includes a mounting base 1 and a rotating shaft 2 movably arranged on the mounting base 1, a first base 3 is fixedly provided on the mounting base 1, a second base 4 is fixedly provided on the rotating shaft 2, a bottle clamp bracket 6 for mounting a bottle clamp assembly 5 is provided on the second base 4, and an adjustment mechanism 7 for adjusting the opening and closing size of the bottle clamp assembly 5 is provided on the first base 3. The bottle clamp bracket 6, the second base 4 and the first base 3 are surrounded by the outer periphery of the rotating shaft 2 and are arranged in sequence from top to bottom. The adjusting mechanism 7 includes a bottom plate 8 fixedly arranged on the above-mentioned first base 3, and a track plate 9 movably provided on the bottom plate 8. The lower end of the bottle clamp assembly 5 is rotatably provided with a bottle clamp wheel 11 that rests on the outer wall of the above-mentioned track plate 9 to realize the opening and closing of the bottle clamp assembly 5 through an extension rod 10, and when adjusting the height of the bottle clamp bracket 6, the bottle clamp wheel 11 is adjusted in the vertical direction along with the bottle clamp bracket 6. During the adjustment process, the bottle clamp wheel 11 is always located in the plane where the track plate 9 is located, and the above-mentioned track plate 9 is located on the rotation path of the bottle clamp wheel 11. An inclined surface 12 for adjusting the opening and closing size of the above-mentioned bottle clamp assembly 5 is provided on the outer wall of the track plate 9, and an opening and closing connection component 13 for adjusting the position of the track plate 9 is provided on the bottom plate 8. The bottle clamp bracket 6 is provided with a feeding station 14 and a discharging station 15 in sequence along the rotation direction of the bottle clamp bracket 6. The two adjustment mechanisms 7 are provided and are respectively located on the above-mentioned feeding station 14 and discharging station 15. The inclined surface 12 on the track plate 9 in the two adjustment mechanisms 7 is always located on the feeding station 14 and the discharging station 15.

[0034] The bottle mouth is clamped by the bottle clamp assembly 5 disposed on the bottle clamp bracket 6. When changing bottles of different sizes, the position of the track plate 9 can be conveniently adjusted through the opening and closing connection assembly 13, so that the position of the inclined surface 12 at the feeding station 14 and the discharging station 15 is changed, thereby adjusting the opening and closing size of the bottle clamp assembly 5 at the feeding station 14 and the discharging station 15. The structure is simple and the adjustment is relatively convenient. The bottle clamp assembly 5 always rotates with the bottle clamp bracket 6. When passing through the adjustment mechanism 7, the bottle clamp assembly 5 is opened for loading or unloading. By adjusting the position of the inclined surface 12 at the feeding station 14 and the discharging station 15, the distance between the inclined surface 12 and the bottle clamp assembly 5 at the feeding station 14 and the discharging station 15 can be adjusted, thereby achieving the adjustment of the opening and closing size of the bottle clamp assembly 5.

[0035] A lower plate 16 is fixedly mounted on the base plate 8. The lower plate 16 is provided with an arcuate groove 17 for engaging the track plate 9. The center of the arcuate groove 17 coincides with the center of the first base 3. A pressure plate 18 is fixedly mounted on the base plate 8 for pressing the track plate 9 against the arcuate groove 17. A limiting groove 19 extending along the arcuate groove 17 is formed at the upper end of the track plate 9. A pressure block 20 is fixedly mounted at the lower end of the pressure plate 18 for engaging with the limiting groove 19. The opening and closing connection assembly 13 includes a power assembly 21 fixedly mounted on the base plate 8. A downwardly extending opening and closing shaft 22 is fixedly mounted on the track plate 9. The lower end of the opening and closing shaft 22 is movably mounted on the power assembly 21 via a connecting plate 23. The two ends of the connecting plate 23 are rotatably mounted on the opening and closing shaft 22 and the power assembly 21, respectively. A sensing bracket 24 is fixedly mounted on the bottom plate 8 and positioned below the opening and closing shaft 22. A sensor 25 is fixedly mounted on the sensing bracket 24 for detecting the position of the opening and closing shaft 22. The power assembly 21 drives the track pad 9 to move and adjust its position via the opening and closing shaft 22. The track pad 9 is pressed against the limiting groove 19 by the pressing block 20, so that the track pad 9 can only move along the limiting groove 19.

[0036] The bottle clamp bracket 6 includes an upper bracket 26 and a lower bracket 27, and the above-mentioned bottle clamp assembly 5 is arranged on the upper bracket 26 and the lower bracket 27. The second base 4 is movably provided with a guide assembly 28 that can move the upper bracket 26 in the vertical direction. The first base 3 is provided with a lifting assembly 29 for lifting the above-mentioned upper bracket 26. The upper bracket 26 is provided with a reset assembly 30 for driving the upper bracket 26 to move downward and reset. The second base 4 is provided with a limit assembly 31 for locking the upper bracket 26 after the above-mentioned lifting assembly 29 adjusts the position of the upper bracket 26. The lifting assembly 29 includes a lifting plate 32 arranged above the first base 3. A plurality of lifting forces 33 for lifting the lifting plate 32 are arranged between the lifting plate 32 and the first base 3. The lifting plate 32 is located directly below the upper bracket 26. A plurality of limit assemblies 31 are fixedly provided at the lower end of the upper bracket 26. The limit assemblies 31 include a push rod 34 inserted into the second base 4. The push rod 34 passes through the second base 4 in the vertical direction and the upper end of the push rod 34 is fixedly provided at the lower end of the upper bracket 26. The push rod 34 is located above the lifting plate 32. When the filling equipment needs to replace bottles of different calibers, the lifting force 33 drives the lifting plate 32 to move upward, thereby lifting the lifting plate 32 and driving the push rod 34 to move upward. The push rod 34 drives the upper bracket 26 and the components thereon to rise together to accommodate bottles of different heights. When adjusting the height of the bottle clamp assembly 5, the lifting power 33 on the first base 3 drives the lifting plate 32 to move upward, and the lifting plate 32 lifts the push rod 34, and the lifting and lowering of the bottle clamp bracket 6 is realized by the push rod 34 fixed on the upper bracket 26. Bottle clamp brackets 6 of different heights are used to adapt to different types of bottles. The thickness of the support rings on the bottle mouths of different types is different, which prevents the support ring at the bottle mouth from hitting the bottle clamp assembly 5 during clamping.

[0037] The limiting assembly 31 includes a push block 35 movably mounted on the second base 4. The push rod 34 passes through the push block 35. The push block 35 is provided with a guide slot 36 extending along the length of the push block 35. The push rod 34 is inserted into the guide slot 36. A limiting plate 37 is fixedly mounted on the push rod 34. The limiting plate 37 is located above the push block 35. The push block 35 is provided with a groove 38 for engaging the limiting plate 37. A locking plate 39 is fixedly mounted at one end of the push block 35. A locking seat 40 is fixedly mounted on the second base 4. The locking plate 39 is located above the locking seat 40. A locking pin 41 is movably mounted on the locking seat 40 via a threaded connection and passes through and secures the locking plate 39. After the height of the upper bracket 26 is adjusted by the lifting assembly 29, the limit plate 37 on the push rod 34 moves upward with the push rod 34 and disengages the groove 38. The position of the push block 35 is adjusted by pushing the limit plate 37 so that it presses against the push block 35. After the push block 35 is adjusted into position, the lifting power 33 stops, and the reset assembly 30 and the guide assembly 28 use their own forces to lower the bottle clamp upper bracket 26 and its components to a stable position, thus completing the position fixation of the upper bracket 26. After the lifting support plate 32 lifts the push rod 34, the operator manually pushes the push block 35 to move it along the length of the guide groove 36 on the push block 35, and the limit plate 37 on the push rod 34 is respectively engaged with the groove 38 or the push block 35, thereby achieving the switching of different heights and fixing the position of the limit plate 37. After the push block 35 is adjusted to the specified position, the locking plate 39 is fixed by tightening the locking pin 41 to complete the locking of the push block 35.

[0038] The guide assembly 28 includes a cylinder 43 fixed to the second base 4. The cylinder 43 vertically extends through the upper bracket 26. A mounting block 44 is fixed to the upper end of the cylinder 43. Two downwardly extending connecting shafts 45 are fixed to the mounting block 44. The lower ends of the connecting shafts 45 are fixed to the upper bracket 26, and the two connecting shafts 45 are located on either side of the cylinder 43. The reset assembly 30 includes a buffer shaft 46 fixed to the second base 4. The buffer shaft 46 extends upward and extends through the upper bracket 26. A buffer sleeve 47 is fixed to the upper end of the buffer shaft 46. The buffer sleeve 47 houses an elastic member 48 for driving the upper bracket 26 downward. The lower end of the elastic member 48 abuts against the upper end surface of the upper bracket 26. The distance between the buffer sleeve 47 and the second base 4 is greater than the thickness of the upper bracket 26. The elastic member 48 is a spring. The length of the push rod 34 below the second base 4 is greater than the distance between the buffer sleeve 47 and the second base 4. When the upper bracket 26 is driven to move by the lifting plate 32, the moving direction of the bottle clamp bracket 6 is limited and guided by the guide assembly 28, and a downward force is always provided to the upper bracket 26 by the elastic member 48 sleeved on the buffer shaft 46. During use, the push rod 34 on the upper bracket 26 is always pressed against the push block 35 to fix the upper bracket 26.

[0039] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible.
