DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0022] like Figure 1-6As shown, a lifting mechanism of a filling clamping device 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, the bottle clamp bracket 6 includes an upper bracket 26 and a lower bracket 27, the bottle clamp assembly 5 is arranged on the upper bracket 26 and the lower bracket 27, a guide assembly 28 capable of moving the upper bracket 26 in a vertical direction is movably provided on the second base 4, a lifting assembly 29 for lifting the upper bracket 26 is provided on the first base 3, a resetting assembly 30 for driving the upper bracket 26 to move downward and reset is provided on the upper bracket 26, and a limiting assembly 31 for locking the upper bracket 26 after the lifting assembly 29 adjusts the position of the upper bracket 26 is provided on the second base 4. 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 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 directly 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.

[0023] The limiting assembly 31 includes a push block 35 movably mounted on the second base 4. The push rod 34 extends through the push block 35. The push block 35 defines a guide slot 36 extending along the length of the push block 35, into which the push rod 34 is inserted. A limiting plate 37 is fixedly mounted on the push rod 34. The limiting plate 37 is positioned above the push block 35. The push block 35 defines 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 positioned above the locking seat 40. A locking pin 41 is movably mounted on the locking seat 40 via a threaded connection, extending through the locking plate 39 and securing the locking plate 39. A knob 42 is provided at the top end of the locking pin 41. 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.

[0024] 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.

[0025] 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. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising from these variations or modifications to the specification remain within the scope of protection of this utility model.
