[0001] The utility model relates to the technical field of filling machines, in particular to a star disk protection device on a filling machine. Background Art

[0002] At present, filling and capping machines are mainly used for filling liquids or pastes in the fields of daily chemical products, food, and medicine. Most of the existing filling equipment has realized an integrated design, which can perform a series of processes such as filling, installing inner plugs, and capping, and has high work efficiency. The existing filling and capping devices generally include a conveying mechanism, a filling mechanism, a film-taking mechanism, and a capping mechanism. The conveying mechanism is used to convey the packaging container to each processing station, the filling mechanism is used to fill the liquid or paste into the packaging container, the film-taking mechanism is generally used to set the inner pad cover on the packaging container, and the capping mechanism is to tighten the bottle cap. A controller is also provided, and the working speed and duration of each component are set on the controller.

[0003] The conveying mechanism includes a motor and a star disk. A number of slots are evenly arranged along the circumference of the star disk. The packaging containers are clamped into the slots in turn by clamps or transmitted by a transmission belt. The motor drives the star disk to rotate, thereby driving the packaging containers to pass through each workstation in turn. However, during the rotation of the star disk, there may be a collision with the clamps or other components on the workstation. After the collision, the star disk will shift, resulting in inaccurate slot position, affecting the subsequent loading and unloading of packaging containers and affecting the operation of the entire filling and capping machine. Summary of the invention

[0004] Purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides a star disk protection device on a filling machine. After the star disk collides and deviates, an alarm is issued and the motor stops working. After the star disk returns to its original position, the motor continues to work and drives the star disk to rotate.

[0005] The technical solution of the utility model: a star disk protection device on a filling machine, comprising a star disk, a driving assembly for driving the star disk to rotate, and a transmission assembly connecting the star disk and the driving assembly, and also comprising a micro switch, the transmission assembly comprising a synchronously rotating rotating seat, an overloader and an overload upper disk, the overloader is arranged between the rotating seat and the overload upper disk, and the upper end of the overloader passes through the overload upper disk and is connected to the star disk, the rotating seat is connected to the driving assembly, the micro switch is located above the overload upper disk, the overload upper disk and the rotating seat are limitedly matched, when the star disk collides, the overload upper disk and the rotating seat are misaligned, and the overload upper disk moves up relative to the rotating seat to contact the micro switch, and a spring is provided on the overload upper disk.

[0006] By adopting the above technical solution, a protective device is set to prevent the star disk from continuing to work and affecting the filling and capping of the product after it collides and deviates. After the star disk collides, the overload upper disk will deviate synchronously with the star disk and will be misaligned relative to the rotating seat, and will move upward to overcome the resistance pressure of the spring, so that the overload upper disk will contact the micro switch. At this time, the alarm function is triggered and the drive assembly stops working. When the star disk is returned, it only needs to be moved lightly to drive the overload upper disk to move down back to the initial position and correspond to the rotating seat, and the drive assembly starts working again.

[0007] The utility model is further configured as follows: a plurality of pressure rods are provided on the lower end surface of the overload upper plate along its circumference, a plurality of through grooves are correspondingly provided on the overloader, the pressure rods extend into the through grooves, each through groove is provided with a marble in contact with the pressure rod, the marble part is exposed outside the through groove, a groove for the marble to be inserted into is provided on the rotating seat, and when the marble is located in the corresponding groove, the overload upper plate is separated from the micro switch.

[0008] The above further arrangement has a simple structure and is easy to operate. When the overload upper plate is misaligned with the rotating seat, the marble breaks away from the groove and contacts the portion of the rotating seat where no groove is set. Since the portion without a groove is higher than the groove, the marble drives the pressure rod, and the overload upper plate moves upward relative to the rotating seat. When the star plate returns to its position, the marble re-enters the groove, the overload upper plate moves downward, separates from the micro switch, and the alarm is released.

[0009] The utility model is further configured as follows: the overloader is provided with a first connecting column, the first connecting column passes through the overload upper disk and is connected to the star disk, and the spring sleeve is arranged outside the first connecting column and contacts with the overload upper disk.

[0011] The present invention is further configured as follows: a second connecting column is provided at the lower end of the overloader, and the second connecting column extends into the rotating seat and is connected to the rotating seat through a bearing.

[0012] By adopting the above further arrangement, the components of the transmission assembly are structurally stable, and they rotate synchronously under the action of the driving assembly to drive the star plate to rotate.

[0013] The utility model is further configured as follows: a connecting seat is provided at the lower end of the star plate, and the upper end of the first connecting column is inserted into the connecting seat and connected by a fastener.

[0026] like Figure 1-6 As shown, a star disk protection device on a filling machine includes a star disk 1, a driving assembly 2 for driving the star disk 1 to rotate, and a transmission assembly 3 connecting the star disk 1 and the driving assembly 2. The driving assembly 2 includes a divider and a motor. The motor is connected to the divider through a chain and a sprocket. The motor and the divider are both prior art. The motor and the sprocket are not shown in the figure and also include a micro switch 4. The micro switch 4 is fixed to the frame of the filling machine through a mounting seat. The transmission assembly 3 includes a synchronously rotating rotating seat 31, an overloader 32 and an overload upper disk 33. The rotating seat 31 is arranged on the divider and rotates under the action of the divider. The overloader 32 is arranged between the rotating seat 31 and the overload upper disk 33, and the upper end of the overloader 32 passes through the overload upper disk 33 to be connected to the star disk 1. The rotating seat 31 is connected to the driving assembly 2. The micro switch 4 The overload upper plate 33 is located above the overload upper plate 33, and the overload upper plate 33 is limitedly matched with the rotating seat 31. When the star plate 1 collides, the overload upper plate 33 is misaligned with the rotating seat 31, and the overload upper plate 33 moves up relative to the rotating seat 31 and contacts the micro switch 4. A spring 5 is provided on the overload upper plate 33, and a protective device is provided to prevent the star plate 1 from continuing to work after the collision and deviation, affecting the filling and capping of the product. After the star plate 1 collides, the overload upper plate 33 is synchronously offset with the star plate 1, and will be misaligned relative to the rotating seat 31, and move upward to overcome the resistance pressure of the spring 5, so that the overload upper plate 33 contacts the micro switch 4. At this time, the alarm function is triggered, and the drive assembly 2 stops working. When the star plate 1 performs the return operation, it only needs to move the star plate 1 slightly to drive the overload upper plate 33 to move down to the initial position, and correspond to the rotating seat 31, and the drive assembly 2 starts working again.

When the marble 6 is located in the corresponding groove 311, the overload upper plate 33 and the micro-motion The switch 4 is separated, the structure is simple, and the operation is convenient. When the overload upper plate 33 is misaligned with the rotating seat 31, the marble 6 disengages from the groove 311, and the marble 6 contacts the part of the rotating seat 31 where the groove 311 is not set. Because the part where the groove 311 is not set is higher than the groove 311, the marble 6 drives the pressure rod 331, and then the overload upper plate 33 will move up relative to the rotating seat 31. When the star plate 1 returns to its position, you only need to gently move the star plate 1 to re-enter the groove 311, and the overload upper plate 33 moves down and separates from the micro switch 4, the alarm is lifted, and the operation is convenient.

[0028] The overloader 32 is provided with a first connecting column 322, which passes through the overload upper plate 33 and is connected to the star disk 1. The spring 5 is sleeved outside the first connecting column 322 and contacts the overload upper plate 33, so the structure is firm and the installation of the spring 5 is convenient. The lower end of the overloader 32 is provided with a second connecting column 323, which extends into the rotating seat 31 and is connected to the rotating seat 31 through a bearing, so that the structure between the various components of the transmission assembly 3 is stable, and the star disk 1 is driven to rotate synchronously under the action of the driving assembly 2. The lower end of the star disk 1 is provided with a connecting seat 11, and the upper end of the first connecting column 322 is inserted into the connecting seat 11 and connected by a fastener, which is set by a screw and screwed in from the top of the star disk, so that the structure between the overloader 32 and the star disk 1 is firm and the star disk 1 is driven to rotate better.
