Description

Technical Field

[0001] This utility model relates to the field of liquid packaging machines, and in particular to a star wheel motor base positioning structure for a liquid packaging machine. Background Technology

[0002] The transmission systems of liquid packaging machinery, such as filling, capping, and bottle washing machines, can be linear or rotary star wheel systems. Linear systems are often used in single-machine linear packaging machines, while rotary star wheel systems are used in larger, high-speed packaging equipment, offering high speed and output. A rotary star wheel mainly consists of a star wheel base, with a star wheel mounted on the bottom of the base via bearings. One side of the star wheel has a mounting hole containing a star wheel gear. Each station's star wheel requires a motor, whose gear meshes with the star wheel gear on its motor shaft to drive the star wheel to rotate at the bottom of the star wheel base, thus pushing the bottle. Both the star wheel base and the motor are mounted on a base frame. The mounting plate at the top of the base frame is connected to the star wheel base, while the base at the bottom of the base frame houses the motor. A gap is provided between the mounting plate at the top of the base frame and the base at the bottom of the base frame. The motor shaft extends upwards, with gears on the motor shaft meshing with the star wheel gear. The motor base is fixed to the base at the bottom of the base frame. The main method for positioning the star wheel motor base is for the installer to move the motor base directly to the base at the bottom of the base plate frame, and then gradually adjust the motor shaft to align with the mounting holes on one side of the star wheel. After alignment, the gear is installed and meshes with the star wheel gear. Then, the motor base is welded and fixed to the base at the bottom of the base plate frame. This requires the assembler to have a high level of experience, otherwise the meshing between the motor shaft gear and the star wheel gear will be either too loose or too tight, thus affecting the rotation of the star wheel. Utility Model Content

[0003] The purpose of this utility model is to provide a convenient positioning structure for the star wheel motor base of a liquid packaging machine, so as to avoid the meshing between the motor shaft gear and the star wheel gear being either too loose or too tight, which would affect the rotation of the star wheel.

[0004] The positioning structure of the star wheel motor base of the liquid packaging machine of this utility model includes a positioning hole on the top of the mounting plate of the base frame above the mounting hole on one side of the star wheel. The positioning hole is aligned with the mounting hole and is coaxial with the mounting hole. After the mounting hole on one side of the star wheel is removed, the top of the positioning rod is detachably installed in the positioning hole. The bottom of the positioning rod is fitted with a positioning sleeve that can move upward on the positioning rod. The bottom of the positioning sleeve is provided with a positioning part that positions on the base at the bottom of the base frame. The outer edge of the positioning part is fitted with a mounting plate that is welded and fixed to the base at the bottom of the base frame. The mounting plate is provided with a mounting plate hole that cooperates with the positioning part so that the positioning part can be disengaged from the mounting plate when the positioning sleeve moves upward. The mounting plate is also provided with a screw hole for mounting the motor base so that the motor shaft is coaxial with the positioning hole.

[0005] As a preferred embodiment of this utility model, the top of the positioning rod is provided with an embedding part for embedding into the positioning hole, and a snap-fit ​​part is provided between the embedding part and the top of the positioning rod, which is tightly fitted to the mounting plate at the top edge of the positioning hole. The snap-fit ​​part is provided with a first bolt hole, and a second bolt hole is provided on the mounting plate at the top of the base plate frame on the edge side of the positioning hole that cooperates with the first bolt hole. After the positioning rod is embedded into the positioning hole by the embedding part, it is detachably installed in the positioning hole by inserting a bolt through the first bolt hole to the second bolt hole.

[0006] As a preferred embodiment of this utility model, the lower section of the positioning rod is provided with a limiting plate for the positioning sleeve to move upward and limit the movement.

[0007] As a preferred embodiment of this utility model, the inner diameter of the positioning sleeve is slightly larger than the outer diameter of the lower section of the positioning rod.

[0008] As a preferred embodiment of this utility model, the positioning part is a disc-shaped positioning part, which is located at the bottom of the positioning sleeve. The mounting plate hole is a circular mounting plate hole that mates with the disc-shaped positioning part. The circular mounting plate hole is fitted around the outer edge of the disc-shaped positioning part, and a clearance fit is provided between the disc-shaped positioning part and the circular mounting plate hole.

[0009] As a preferred embodiment of this utility model, the disc-shaped positioning part has four fan-shaped windows evenly arranged in the circumferential direction.

[0010] The positioning structure of the star wheel motor base of the liquid packaging machine of this utility model has a positioning hole on the top mounting plate of the base frame above the mounting hole on one side of the star wheel. The positioning hole is aligned with the mounting hole and coaxial with the mounting hole. After the mounting hole on one side of the star wheel is removed, the positioning sleeve is inserted from the bottom of the positioning rod, and the top of the positioning rod is installed in the positioning hole. At this time, the positioning part at the bottom of the positioning sleeve is positioned on the base at the bottom of the base frame. Then, the outer edge of the positioning part of the positioning sleeve is moved up and inserted into the mounting plate, which can position the mounting plate on the base at the bottom of the base frame. Then, the mounting plate is welded and fixed on the base at the bottom of the base frame. The positioning rod and the positioning sleeve are removed, and the motor base can be installed in the screw hole of the mounting plate. The motor shaft and the mounting hole on one side of the star wheel can be matched to install the gear and the star wheel gear to mesh with each other. This structure makes it easier to position the motor base, thereby avoiding the meshing of the gear on the motor shaft and the star wheel gear being either too loose or too tight, which would affect the rotation of the star wheel.

[0012] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0013] In this utility model, it should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0014] A star wheel motor base positioning structure for a liquid packaging machine, such as Figure 1-5 As shown, a positioning hole 3 is provided on the top mounting plate 2 of the base frame above the mounting hole 1 on one side of the star wheel, and is coaxial with the mounting hole. After the mounting hole on the star wheel side is removed, the top of the positioning rod 4 is detachably installed in the positioning hole. The bottom of the positioning rod is sleeved with a positioning sleeve 5 that can move upward on the positioning rod. The bottom of the positioning sleeve is provided with a positioning part 7 that is positioned on the base 6 at the bottom of the base frame. The outer edge of the positioning part is sleeved with a mounting plate 8 that is welded and fixed to the base at the bottom of the base frame. The mounting plate is provided with a mounting plate hole 9 that cooperates with the positioning part so that the positioning part can be disengaged from the mounting plate when the positioning sleeve moves upward. The mounting plate is also provided with a screw hole 10 for mounting the motor base so that the motor shaft is coaxial with the positioning hole.

[0015] like Figure 2 and Figure 3 The positioning rod shown has an embedding part 11 at the top of the positioning hole, and a snap-fit ​​part 12 between the embedding part and the top of the positioning rod is provided on the mounting plate at the top edge of the positioning hole. The snap-fit ​​part is provided with a first bolt hole 13, and a second bolt hole 14 is provided on the mounting plate at the top of the base plate frame on the edge side of the positioning hole that cooperates with the first bolt hole. After the positioning rod is embedded into the positioning hole by the embedding part, it is detachably installed in the positioning hole by inserting a bolt from the first bolt hole to the second bolt hole.

[0016] The star wheel 18 is mounted on the bottom of the wheel seat 17 via a bearing. The mounting hole 1 is located on one side of the star wheel, as shown below. Figure 2After the mounting hole on one side of the star wheel is moved away from the left, the positioning sleeve is inserted from the bottom of the positioning rod. The top of the positioning rod is then inserted into the positioning hole through the embedding part 11, and is tightly fastened to the mounting plate 2 on the top edge of the base plate frame by the snap-fit ​​part 12. The snap-fit ​​part 12 is a circular snap-fit ​​part 12. Four first bolt holes 13 are evenly arranged around the circumference of the circular snap-fit ​​part 12. Four second bolt holes 14 are also provided on the mounting plate on the top of the base plate frame. By inserting bolts through the first bolt holes 13 to the second bolt holes 14, the positioning rod is fixed. When disassembling the positioning rod, the bolts are unscrewed from the first bolt holes 13 and the second bolt holes 14. Then, the motor base is installed in the screw hole 10 of the mounting plate so that the motor shaft and the mounting hole on one side of the star wheel can be fitted together to install the gear and mesh with the star wheel gear. The inner diameter of the positioning hole 3 is 100mm, the outer diameter of the insert part 11 is 98mm, the length of the insert part 11 is 14mm, the outer diameter of the snap-fit ​​part 12 is 166mm, and the length of the positioning rod is 250mm.

[0017] The lower section of the positioning rod is equipped with a limiting plate 15 for limiting the upward movement of the positioning sleeve. When the top of the positioning sleeve moves to the limiting plate 15, the movement is complete. The positioning part 7 at the bottom of the positioning sleeve can then be fitted onto the mounting plate for easier positioning. Furthermore, because the inner diameter of the positioning sleeve is slightly larger than the outer diameter of the lower section of the positioning rod, the positioning sleeve can easily move up and down on the positioning rod, facilitating positioning. The lower section of the positioning rod is 184mm long, and the outer diameter of the limiting plate 15 is 65mm. The positioning sleeve has an outer diameter of 65mm, an inner diameter of 50mm, and a length of 450mm.

[0018] like Figure 4 and Figure 5 As shown, the positioning part is a disc-shaped positioning part, located at the bottom of the positioning sleeve. The outer diameter of the disc-shaped positioning part is larger than the outer diameter of the positioning sleeve. The mounting plate hole is a circular mounting plate hole that mates with the disc-shaped positioning part, fitting around the outer edge of the disc-shaped positioning part. A clearance fit is established between the disc-shaped positioning part and the circular mounting plate hole. The disc-shaped positioning part has four evenly spaced fan-shaped windows 16 along its circumference, which reduces its weight and facilitates positioning. The circular mounting plate hole has four evenly spaced screw holes 10 along its circumference, facilitating the fixing of the motor base with bolts. The outer diameter of the positioning part is 350mm, and the inner diameter of the mounting plate hole is 349.9mm.
