Description

Technical Field

[0001] This utility model relates to the field of filling machine technology, specifically to a positioning structure for an oral liquid filling machine. Background Technology

[0002] During the oral liquid filling process, bottles are sequentially conveyed by a conveyor belt to the positioning slots on a turntable. As the turntable rotates, the filling, capping, and sealing processes are completed. The positioning slots on the turntable, along with the limiting arc plates on the edges of the slots, are used to position the bottles, ensuring the accuracy of filling and sealing.

[0003] A Chinese patent application (CN 209193525 U) discloses a rotary layout mechanism for a filling machine. The mechanism includes: a horizontally extending mounting frame; a filling machine with a filling port, positioned at the upper end of the mounting frame; and a layout mechanism positioned at the lower end of the mounting frame. The layout mechanism comprises an upper rotary table, a lower rotary table, and a protective ring. The layout mechanism has a rotation axis perpendicular to its length direction, allowing it to rotate around this axis. During rotation, the layout mechanism moves multiple workstations sequentially to directly below the filling port, with each workstation corresponding to a weighing pan. This design prevents the can from falling off, ensuring high reliability. The protective ring protects the weighing pans and motor within the layout mechanism, and also isolates any fluid splashed from the filling port from the upper rotary table, further enhancing the safety of the design.

[0004] Traditional filling machines use a single-specification positioning slot. When filling oral liquid bottles of different diameters or heights, the original support plate must be disassembled and the matching positioning slot module replaced, a time-consuming and labor-intensive process. Therefore, a positioning structure for oral liquid filling machines is needed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a positioning structure for an oral liquid filling machine to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution: This utility model relates to a positioning structure for an oral liquid filling machine, comprising: The positioning component includes a first support plate and a first positioning groove. The first support plate is sleeved and fixed on the support column at the upper end of the turntable, and the first positioning groove is evenly opened on the edge of the first support plate. An adjustment assembly includes a second support plate, a second positioning groove, a third positioning groove, a third support plate, a first opening, a rod, a connecting ring, a first positioning hole, a second positioning hole, and a third positioning hole. The second support plate is sleeved on a support column at the upper end of the turntable. The second and third positioning grooves are evenly and alternately formed on the edge of the second support plate. The third support plate is sleeved on and fixed to the support column at the upper end of the turntable. The first opening is evenly formed on the third support plate. The rod is inserted into the first opening. The connecting ring is fixed to the upper end of the rod. The first positioning hole is evenly formed on the first support plate. The second and third positioning holes are evenly formed on the second support plate.

[0006] Furthermore, the adjustment assembly also includes a spring and a T-shaped pull tube. The spring is sleeved on the upper end of the insertion rod, with one end fixed to the upper end of the third support plate and the other end fixed to the lower end of the connecting ring. The T-shaped pull tube is fixed to the upper end of the connecting ring.

[0007] Furthermore, when the second positioning groove is aligned with the first positioning groove, the insertion rod is sequentially inserted into the second positioning hole and the first positioning hole.

[0008] Furthermore, when the third positioning groove is aligned with the first positioning groove, the insertion rod is sequentially inserted into the third positioning hole and the first positioning hole.

[0009] Furthermore, the positioning component also includes a limiting arc plate, which is fixed on the turntable base and wraps around the outside of the turntable and the first support plate.

[0010] Furthermore, it also includes a limiting component, which includes a positioning rod and a guide hole. The positioning rod is fixed on the first support plate, and the guide hole is opened on the second support plate, with the positioning rod inserted into the guide hole.

[0011] Furthermore, the limiting component also includes a threaded hole and a connecting rod. The threaded hole is formed on the first support plate, and the connecting rod is fixed to the lower end of the positioning rod and screwed into the threaded hole.

[0012] This utility model has the following beneficial effects: This invention, through its adjustable components, allows for the switching of different sizes of oral liquid when a different specification needs to be filled. The second positioning groove aligns with the first positioning groove, and pulling the T-shaped pull tube upwards moves the connecting ring upwards, simultaneously causing the insertion rod to move upwards along the second and first positioning holes. Once the insertion rod exits the second positioning hole, the second support plate is rotated to align the third positioning groove with the first positioning groove. Releasing the T-shaped pull tube causes the spring to retract, allowing the insertion rod to be inserted into the third and first positioning holes. This design eliminates the need to disassemble the original support plate to switch between different sizes of positioning grooves, significantly shortening changeover time and improving production line response speed.
