Technical Field

The invention relates to the technical field of filling and packaging equipment, in particular to a bottle screwing and rotating mechanism for filling bottles.

Background

In the filling production of liquids such as oral liquids and soft extracts, a rotary-type screw capping device is generally used to perform a capping process on a filling bottle. The rotary type screw capping equipment generally receives filled open filling bottles conveyed from a filling conveyer belt through a bottle body limiting concave part arranged on the peripheral wall of a disc-shaped turntable, drives the open filling bottles to move around the turntable, and then performs screw capping operation through screw capping lifting cylinders arranged in an annular array above the turntable. When the filling bottle is screwed, the belt that still needs set up through carousel side drives the body of filling bottle along the opposite direction rotation of screw cap to improve the closing cap quality. However, according to the disc-shaped turntable, the pressure when the belt is tangent to the filling bottle body is inconsistent, generally, the pressure when the belt on the outer side presses the filling bottle body is larger, and the pressure inwards is smaller, so that the autorotation force of the filling bottle is inconsistent when the filling bottle is screwed, and the quality of the sealing cover is influenced.

Disclosure of Invention

The invention aims to provide a filling bottle cap screwing and rotating mechanism which can improve the autorotation consistency of the filling bottle cap screwing and improve the capping quality.

The filling bottle screw-capping and bottle-rotating mechanism provided by the invention comprises a rotating table, wherein the rotating table comprises a bottom supporting table and a bottle conveying rotating disc which are coaxially arranged, and the key point is that the bottle conveying rotating disc is in a regular polygon shape, a bottle body limiting concave part is arranged at the joint of two adjacent sides of the bottle conveying rotating disc, a belt for driving a bottle body of a filling bottle to rotate is arranged beside the bottle conveying rotating disc, and the belt sequentially passes through the outer sides of the three adjacent bottle body limiting concave parts.

According to the filling bottle cap screwing and bottle rotating mechanism, the bottle conveying rotary disc is optimized to be a regular polygon, and the belt sequentially passes through the outer sides of the adjacent three bottle body limiting concave parts, so that the belt simultaneously drives the three filling bottles which are distributed in a triangular shape to rotate, the pressure of the three filling bottles on the belt can be more balanced, the consistency of the rotation of the filling bottle cap screwing is improved, and the cap sealing quality is improved.

Further, the regular polygon is a regular hexagon.

Further, the belt is driven by a roller set, the roller set comprises an end positioning roller, a tensioning roller and a driving roller.

Further, revolving stage and roller set all set up on the workstation, the workstation is equipped with bar fretwork groove, the roller of drive roller passes bar fretwork groove is fixed through location bearing. The mounting position of the driving roller can be adjusted through the strip-shaped hollow groove, the position of the driving roller can be adjusted after the roller surface of the driving roller is worn, and the tensioning force of a belt and the advancing speed of the belt are guaranteed.

As can be seen from fig. 1, in operation, the belt 4 is constantly kept tangential to the body of the 3 filling bottles a.

According to the filling bottle cap screwing and bottle rotating mechanism, the bottle conveying rotary disc 3 is optimized to be a regular polygon, and the belt 4 sequentially passes through the outer sides of the adjacent three bottle body limiting concave parts 31, so that the belt 4 simultaneously drives the three filling bottles A distributed in a triangular shape to rotate, the pressure of the three filling bottles A on the belt 4 can be more balanced, the consistency of cap screwing and rotation of the filling bottles A is improved, and the cap sealing quality is improved.

In a preferred embodiment, the regular polygon is a regular hexagon. The filling of the filled bottles a and the transfer to the subsequent process can thus take place from three body limiting recesses 31 above the bottle carousel 3 as shown in fig. 1.

Preferably, the belt 4 is driven by a set of rollers comprising an end positioning roller 41, a tensioning roller 42 and a driving roller 43.

Preferably, the rotating platform 1 and the roller set are both disposed on the working platform 5, the working platform 5 is provided with a strip-shaped hollow-out slot 51, and the roller shaft 431 of the driving roller 43 passes through the strip-shaped hollow-out slot 51 and is fixed by a positioning bearing 432, as shown in fig. 2. Therefore, the installation position of the driving roller 43 can be adjusted through the strip-shaped hollow groove 51, the position of the driving roller 43 can be adjusted after the roller surface of the driving roller 43 is worn, and the tension of the belt 4 and the advancing speed of the belt are guaranteed.

The invention has been described in connection with the accompanying drawings, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of the components set forth in the following description, as long as the invention is capable of being practiced without modification in any way whatsoever, and is capable of other applications without departing from the spirit and scope of the invention as defined by the appended claims.
