Description

Technical Field

[0001] The utility model relates to the technical field of filling equipment, in particular to a limit adjustment mechanism. Background Art

[0002] Many bottle clamps are usually installed in filling equipment, and the bottle clamps usually include a weighing component and a bottle clamping component. In the existing bottle clamps, the bottle clamping component is directly fixedly connected to the weighing component, which results in the inability to adjust the bottle clamp after it is installed on the equipment. During installation, the actual position of the bottle clamping component will be slightly different from the theoretical position due to the influence of the accuracy of the parts themselves, the hole position accuracy, and the assembly accuracy. Since the position of the bottle clamping component cannot be adjusted, the requirements for installation accuracy are significantly increased, and it brings difficulties to the installation. Utility Model Content

[0003] In order to solve the above problems existing in the prior art, the utility model provides a limit adjustment mechanism which is easy to install, easy to adjust and has stable limit.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A limit adjustment mechanism is arranged between the core shaft of a weighing assembly and a bottle clamping assembly, comprising a connecting seat and an adjusting piece, wherein the bottle clamping assembly is connected to the connecting seat; the connecting seat is provided with a connecting hole and an adjusting hole vertically distributed with the connecting hole, the adjusting piece slides through the adjusting hole, the end of the core shaft is inserted into the connecting hole to form a sliding connection, a slot is provided on the side of the adjusting piece corresponding to the core shaft, and a locking piece is provided at the end of the adjusting piece for driving the adjusting piece to axially displace so that the slot clamps the core shaft.

[0006] After the weighing assembly is fixed, the axial position and circumferential position of the core shaft and the connecting hole are adjustable. After being adjusted to the appropriate position, the adjusting piece is locked by the locking piece to achieve the positioning of the core shaft and the connecting seat.

[0007] Preferably, the adjusting member is a columnar structure, the locking member is a nut, one end of the adjusting member extends out of the connection seat and is provided with a thread at the end, and the nut is tightly connected to the thread. Rotating the nut causes the adjusting member to move axially, and the side wall of the clamping groove clamps the surface of the mandrel to form a clamping position.

The arc groove matches the outer side surface of the mandrel to better clamp and position, and it is also convenient for relative rotation adjustment between the mandrel and the connecting hole when the locking member is released.

[0009] Preferably, an annular gasket is provided at a position between the nut and the connecting seat on the adjusting member, and a spring gasket is provided between the annular gasket and the nut. The annular gasket cooperates with the spring gasket to make the nut more stably fastened and not easy to loosen.

[0010] Preferably, the other end of the adjusting member extends out of the adjusting hole and is provided with a positioning plane on the side of the end. When adjusting the nut, the other end of the adjusting member can be positioned with the positioning plane by a tool.

[0011] Preferably, an axial hole is provided on the connecting seat, a rotating member is provided in the axial hole, the bottle clamping assembly is rotatably connected to the connecting seat via the rotating member, and the axis of the rotating member is perpendicular to the axis of the core shaft; a second adjusting member for positioning the rotating member is provided on the connecting seat, and the cooperation mode between the second adjusting member and the rotating member is the same as the cooperation mode between the adjusting member and the core shaft.
