Description

Technical Field

[0001] This utility model relates to the field of filling machine technology, and in particular to a filling positioning structure for a filling machine. Background Technology

[0002] Filling machines are a small category of packaging machines. From the perspective of packaging materials, they can be divided into liquid filling machines, paste filling machines, powder filling machines, and granule filling machines. From the perspective of the degree of automation in production, they can be divided into semi-automatic filling machines and fully automatic filling production lines. Recently, with the implementation of QS certification for food, edible oil manufacturers have begun to pay attention to product quality and packaging, so oil filling machines have become more prominent among filling machines.

[0003] During the linear filling process of a filling machine, the lack of a fixing mechanism around the bottle may cause the bottle's position to deviate, making it prone to tipping over during filling, resulting in bottle damage and production line contamination. Although some filling machines have clamping and fixing mechanisms that can clamp and assist in positioning the bottle, their structure is relatively simple and has poor adaptability to different types of bottles and bottles with complex curved surfaces.

[0004] Therefore, to address the above issues, a filling machine positioning structure can be designed by adding an adaptive mechanism to the clamping mechanism, which allows the clamping mechanism to automatically adjust its posture according to the shape of the bottle, thereby enhancing the clamping and positioning effect of the bottle. Utility Model Content

[0005] To overcome the problem that the lack of a fixing mechanism around the bottle during the straight filling process of the filling machine may cause the bottle to deviate in position, making it easy for the bottle to tip over during filling, resulting in bottle damage and production line contamination, although some filling machines have clamping and fixing mechanisms to clamp and fix the bottle for auxiliary positioning, the structure is relatively simple and has poor adaptability to different filling bottles and filling bottles with complex curved surfaces.

[0006] The technical solution of this utility model is as follows: a filling machine positioning structure, including a conveyor, a movable platform, and a drive assembly. The drive assembly is provided at the bottom of the conveyor, and movable platforms are provided on both sides of the conveyor. The movable platforms are slidably connected to the conveyor.

The drive gear meshes with the driven rack. A guide rod is provided on the inner side of the movable platform. Multiple sets of guide rods are provided and slidably connected to the movable platform. A clamping plate is provided at one end of the guide rod. The clamping plate is rotatably connected to the guide rod. A spring is provided between the clamping plate and the movable platform.

[0007] Preferably, the drive assembly includes a drive motor, a first pulley, a second pulley, and a transmission belt. A support plate is provided at the bottom of the drive gear, and a second pulley is provided at the bottom of the support plate.

[0008] Preferably, the bottom of the two clusters of the conveyor is provided with a lifting seat, the inner side of the lifting seat is provided with a rotating shaft, the rotating shaft is rotatably connected to the lifting seat, one end of the lifting seat is provided with a drive motor, the drive motor is fixedly connected to the lifting seat, the middle position of the rotating shaft is provided with a first pulley, and a transmission belt is provided between the first pulley and the second pulley.

[0009] Preferably, support platforms are provided on both sides of the conveyor, and guide rails are provided between the support platforms and the movable platform.

[0010] Preferably, a connecting rod is provided at the bottom of the movable platform, which is fixedly connected to one end of the conveyor, and a diagonal brace is provided above the movable platform.

[0011] Preferably, the clamping plate has a ball head on the side near the guide rod, the guide rod has a connecting seat on the end near the clamping plate, the connecting seat has a connecting block on its inner side, the connecting block and the connecting seat are slidably connected, and the connecting block and the connecting seat have spherical grooves.

[0012] Preferably, the inner side of the connecting seat is provided with a bolt, which is threadedly connected to the connecting block. One end of the bolt is provided with a force-bearing block, and the end of the guide rod away from the clamping plate is provided with a limit block.

[0013] The beneficial effects of this utility model are:

[0014] By setting up a drive assembly to drive the drive gear to rotate, the two sets of driven racks move in opposite directions, thereby bringing the two sets of movable platforms closer together to clamp the filling bottle and push the filling bottle to center. During the clamping process, the clamping plate contacts the bottle first. Since the clamping plate and the guide rod are rotatably connected, the clamping plate will rotate according to the shape of the bottle during its movement. At the same time, the sliding connection between the guide rod and the movable platform allows multiple sets of clamping plates to form a shape that fits the filling bottle more closely, thereby enhancing the clamping and positioning ability of the filling bottle. The spring can provide thrust to the clamping plate, so that the clamping plate can maintain a strong clamping force. Attached Figure Description

A spring 8 is installed between the two platforms 2. The drive assembly drives the drive gear 4 to rotate, which in turn drives the two sets of driven racks 3 to move in opposite directions. This causes the two sets of movable platforms 2 to move closer to each other to clamp the filling bottle and push the filling bottle to center. During the clamping process, the clamping plate 5 contacts the bottle first. Since the clamping plate 5 is rotatably connected to the guide rod 7, it will rotate according to the shape of the bottle during the movement of the clamping plate 5. At the same time, the sliding connection between the guide rod 7 and the movable platform 2 allows multiple sets of clamping plates 5 to form a shape that fits the filling bottle more closely, thereby enhancing the clamping and positioning ability of the filling bottle. The spring 8 can provide a pushing force to the clamping plate 5, so that the clamping plate 5 can maintain a strong clamping force.

[0022] Please see Figure 2In this embodiment, the drive assembly includes a drive motor 901, a first pulley 902, a second pulley 903, and a transmission belt 904. A support plate 101 is provided at the bottom of the drive gear 4, and a second pulley 903 is provided at the bottom of the support plate 101. Lifting seats 104 are provided at the bottom of both clusters of the conveyor 1. A rotating shaft 905 is provided on the inner side of the lifting seat 104, and the rotating shaft 905 is rotatably connected to the lifting seat 104. A drive motor 901 is provided at one end of the lifting seat 104, and the drive motor 901 is fixedly connected to the lifting seat 104. A first pulley 902 is provided at the middle position of the rotating shaft 905. A transmission belt 904 is provided between the first pulley 902 and the second pulley 903. Support platforms 102 are provided on both sides of the conveyor 1. A guide rail 103 is provided between the support platform 102 and the movable platform 2. The support plate 101 is used to support and install the drive gear 4 and the driven rack 3. The hoisting seat 104 is used to support and install the rotating shaft 905 and the drive motor 901. The support platform 102 is used to support and install the movable platform 2. The guide rail 103 slides to connect the movable platform 2 and the support platform 102. The drive motor 901 drives the rotating shaft 905 to rotate. The first pulley 902, the transmission belt 904 and the second pulley 903 are used for transmission to drive the drive gear 4 to rotate.

[0023] Please see Figure 3 In this embodiment, a connecting rod 201 is provided at the bottom of the movable platform 2, and the connecting rod 201 is fixedly connected to one end of the conveyor 1. A diagonal brace 202 is provided above the movable platform 2. The connecting rod 201 connects the driven rack 3 to the movable platform 2, and the diagonal brace 202 is used to enhance the lateral force strength of the movable platform 2.

[0024] Please see Figure 4 In this embodiment, a ball head 6 is provided on the side of the clamping plate 5 near the guide rod 7, and a connecting seat 701 is provided on the end of the guide rod 7 near the clamping plate 5.

A bolt 703 is provided on the inner side of the connecting seat 701 and is threadedly connected to the connecting block 702. A force-bearing block 705 is provided on one end of the bolt 703, and a limit block 706 is provided on the end of the guide rod 7 away from the clamping plate 5. The bolt 703 connects the connecting block 702 and the connecting seat 701, and the ball head 6 is wrapped in the spherical groove 704. The operator can directly turn the force-bearing block 705 by hand to adjust the pressure of the connecting block 702 and the connecting seat 701 on the ball head 6, thereby adjusting the rotational friction of the clamping plate 5. The limit block 706 can prevent the guide rod 7 from separating from the movable table 2.

[0025] During filling, the drive motor 901 drives the rotating shaft 905 to rotate. The first pulley 902, the transmission belt 904, and the second pulley 903 are used for transmission, which drives the drive gear 4 to rotate. This drives the two sets of driven racks 3 to move in opposite directions, so that the two sets of movable platforms 2 move closer to each other under the guidance of the guide rail 103 to clamp the filling bottle and push the filling bottle to the center. During the clamping process, the clamping plate 5 contacts the bottle first. Since the clamping plate 5 is rotatably connected to the guide rod 7 through the ball head 6 and the connecting seat 701, it will rotate according to the shape of the bottle during the movement of the clamping plate 5. At the same time, the sliding connection between the guide rod 7 and the movable platform 2 allows the multiple sets of clamping plates 5 to form a shape that fits the filling bottle more closely, thereby enhancing the clamping and positioning ability of the filling bottle. The spring 8 can provide a pushing force to the clamping plate 5, so that the clamping plate 5 can maintain a strong clamping force.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
