Description

Technical Field

[0001] The utility model relates to a limiting structure for an ointment filling bottle and belongs to the field of ointment processing. Background Art

[0002] Ointment bottles made of plastic are one of the commonly used containers for ointment filling. When the plastic ointment bottles are filled with ointment, multiple limiting structures for limiting the position of the plastic ointment bottles are often installed on a turntable driven by a motor. When the motor is working, the turntable is driven to rotate, so that the plastic ointment bottle is moved to different workstations. The limiting structure includes a round table installed on the turntable for limiting the position of the plastic ointment bottle. Using screws to connect the round table and the turntable is a commonly used fixing method. Since there are many round tables on the turntable, more screws are required to assemble the round table and the turntable. Therefore, a large number of screws are used, which is not conducive to the disassembly and assembly of the round table and the turntable, that is, the disassembly and assembly takes a lot of time. Therefore, it is necessary to design a limiting structure for the ointment filling bottle that improves the disassembly and assembly efficiency. Utility Model Content

The present invention improves the efficiency of disassembly and assembly between the round table and the turntable and reduces the time spent on disassembly and assembly.

[0004] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a limiting structure of an ointment filling bottle, comprising a turntable, a plurality of base plates are equidistantly arranged in an annular shape at the edge of the upper surface of the turntable, a round table is connected and fixed at the middle position of the upper surface of the base plate, and the upper surface of the round table is recessed downward for storing a circular cavity of the ointment bottle, a pressure ring is provided on the upper side of the base plate, the upper surface of the pressure ring is equidistantly provided with a plurality of through holes matching the round table, and the plurality of round tables respectively penetrate the plurality of through holes, and a plurality of positioning rods are evenly installed on the lower surface of the pressure ring, the upper surface of the base plate is provided with two symmetrically arranged upper pin holes, the upper surface of the turntable is provided with a plurality of lower pin holes aligned with the upper pin holes, the lower end of the positioning rod penetrates the channel formed by the upper pin hole and the lower pin hole and extends to the lower side of the turntable, the outer surface of the positioning rod away from the pressure ring is processed with an external thread, and the end of the positioning rod processed with the external thread is threadedly connected with a nut.

[0006] Furthermore, a plurality of evenly arranged through openings for allowing the push rod to pass through the limiting ring are provided on the side of the limiting ring facing the turntable, a plurality of vertical holes aligned with the through openings are equidistantly provided on the lower surface of the turntable, and a storage groove for storing the tube head of the ointment bottle, which is communicated with the circular cavity, is provided in the middle position of the lower surface of the chassis, and the vertical holes are communicated with the storage groove and are concentrically arranged with the storage groove.

[0007] Furthermore, a plurality of small holes are evenly formed on the upper surface of the pressure ring, and one end of the positioning rod is installed in the small hole.

[0010] Beneficial effects of the utility model:

When the motor drives the turntable 1 to stop briefly, the cylinder is used to drive the push rod to move upward, so that the push rod passes through the through opening 10 and the vertical hole 11 and extends into the circular cavity 5, so that the plastic ointment bottle that has been filled and sealed is ejected.

[0024] See Figure 1-Figure 7, a pressure ring 6 is provided on the upper side of the chassis 2, and a plurality of through-holes 17 cooperating with the frustum 3 are opened in an annular shape and equidistantly on the upper surface of the pressure ring 6. A plurality of frustums 3 are respectively penetrated by the plurality of through-holes 17, and a plurality of small holes 18 evenly opened on the lower surface of the pressure ring 6 are installed with positioning rods 9. Two symmetrically arranged upper pin holes 13 are opened on the upper surface of the chassis 2, and a plurality of lower pin holes 15 aligned with the upper pin holes 13 are opened on the upper surface of the turntable 1.

The nut 7 is set on the side of the limiting ring 8 away from the turntable 1 On the other hand, during the installation of the pressure ring 6, the positioning rod 9 is passed through the circular hole 16 on the limiting ring 8. After the nut 7 is screwed on, there is a gap between the nut 7 and the turntable 1 under the limitation of the limiting ring 8. When the positioning rod 9 and the nut 7 cannot be disassembled by normal means, the gap between the limiting ring 8 and the turntable 1 can be used to cut off the positioning rod 9 with the nut 7 threadedly connected to achieve spare disassembly. When assembling again, select two positioning rods 9 from the undamaged positioning rods 9 and screw on the nut 7 to assemble the frustum 3 and the turntable 1.
