Description

Technical Field

[0001] This utility model relates to the field of filling machine clamping technology, specifically to a bottle clamping fixture for a filling machine. Background Technology

[0002] Filling is an important packaging method for bottled liquids. It allows liquid products to be injected into containers quickly and in large quantities, thereby greatly improving the production efficiency of liquid packaging. During the filling process, the bottle is usually held continuously by filling fixtures.

[0003] For example, Chinese patent document CN2717931Y discloses a bottle clamping and transferring device for a large-volume infusion production unit for plastic bottles. It includes a bottle washing machine, a filling machine, a sealing machine, and a bottle transferring mechanism that connects them in series. The bottle transferring mechanism is equipped with a bottle clamping and transferring device, which has two or more transition plates respectively mounted on a drive shaft. Each transition plate includes an inner plate and an outer plate connected to the inner plate. Several bottle clamps are mounted around the outer plate, and each bottle clamp has a roller mounted on its clamping foot. A cam is fixedly mounted on a bearing seat, and the cam is movably connected to the roller. This utility model's bottle clamping and transferring device utilizes bottle clamping transition plates that clamp the bottle neck to complete the bottle transfer between various process systems.

[0004] In the above technical solution, the clamp is kept in a normally closed state by a spring. When the transition plate drives the clamp to rotate to the high point of the cam, the clamp can be opened to release the bottle. Similarly, when the clamp is disengaged from the high point of the cam, the clamp can close under the action of the spring to clamp the bottle.

[0005] However, during actual use, the inventors discovered that in order to avoid damage to the bottle body when clamping it and to ensure the stability of the clamping, the clamping position must avoid the bottle opening. However, in the above technical solution, the installation position of the clamp is constant, which makes it impossible to adjust the installation position of the clamp according to different bottle sizes, thus affecting the overall adaptability. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a bottle clamp for a filling machine, which can adjust the height of the clamps according to different bottle sizes to adapt to the clamping needs of different bottle sizes and expand the scope of application.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a bottle clamp for a filling machine, characterized in that it includes a support plate, on which a liftable connecting plate is provided, wherein there are multiple connecting plates evenly distributed around the circumference, and the connecting plate is provided with an active gripper and a follower gripper, wherein the active gripper and the follower gripper can close towards each other or separate away from each other to achieve clamping or releasing of the bottle, and the connecting plate can be raised and lowered to adjust the height of the active gripper and the follower gripper.

[0008] The present invention is further configured such that: both the active gripper and the follower gripper are provided with magnetic blocks inside, and the magnetic blocks are used to drive the active gripper and the follower gripper to close towards each other.

[0009] The present invention is further configured such that: a synchronous wheel and a motor are provided on the inner side of the bearing plate, there are multiple synchronous wheels, a drive wheel is provided at the output end of the motor, the drive wheel and the synchronous wheel are distributed in a fan shape, a transmission belt is fitted on the outer periphery of the drive wheel and the synchronous wheel, one side of the transmission belt is attached to the inner periphery of the bearing plate, a guide wheel is provided on the opposite side of the synchronous wheel, and the guide wheel is coupled to the inner side of the bearing plate.

[0010] The present invention is further configured such that: a driving arc block is provided on the inner side of the bearing disk, and a coupling wheel is provided at the tail end of the active gripper; the coupling wheel is coupled with the outer side of the driving arc block to push the active gripper and the follower gripper to separate in opposite directions.

[0011] The present invention is further configured such that: the active gripper and the follower gripper are respectively provided with active teeth and driven teeth on their opposing sides, and the active teeth and driven teeth mesh with each other.

[0012] The present invention is further configured such that: an adjusting screw is rotatably connected to the bearing plate in the vertical direction; a connecting plate is fitted around the adjusting screw and forms a threaded fit between the two; a guide rod is provided on the bearing plate; the guide rod is located on both sides of the adjusting screw; and the two ends of the connecting plate are fitted around the guide rod and can form a sliding fit between the two.

[0021] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] like Figures 1 to 4As shown, this utility model discloses a bottle clamp for a filling machine, including a support plate 1. The support plate 1 has multiple liftable connecting plates 2 evenly distributed circumferentially. Each connecting plate 2 has an active gripper 3 and a follower gripper 4, which are rotatably connected to the connecting plate 2 via pins. The active gripper 3 and the follower gripper 4 can close towards each other or separate away from each other to clamp or release the bottle. The connecting plate 2 can be raised and lowered to adjust the height of the active gripper 3 and the follower gripper 4. Specifically, an adjusting screw 13 is rotatably connected to the support plate 1 along the vertical direction via a bearing seat. The connecting plate 2 is fitted around the adjusting screw 13, forming a threaded engagement between them. The carrier plate 1 is provided with a guide rod 14, which is fixed on the carrier plate 1 and located on both sides of the adjusting screw 13. The two ends of the connecting plate 2 are fitted around the outer periphery of the guide rod 14. That is, the two ends of the connecting plate 2 are provided with guide holes opposite to the guide rod 14, which can form a sliding fit between the two. By rotating the adjusting screw 13, the connecting plate 2, which forms a threaded fit with the adjusting screw 13, can be driven to move along the direction of the adjusting screw 13 under the guidance of the guide rod 14. Thus, the height of the active gripper 3 and the follower gripper 4 connected to the connecting plate 2 can be adjusted. In this way, the height of the gripper can be adjusted according to the bottle body of different specifications to adapt to the clamping requirements of different bottle body sizes and expand the scope of application.

[0024] In this embodiment, the structure in which the active gripper 3 and the follower gripper 4 can close towards each other is as follows: both the active gripper 3 and the follower gripper 4 are provided with magnetic blocks. The magnetic blocks are fixed inside the active gripper 3 and the follower gripper 4 respectively by a secondary injection molding process. That is, the blanks of the active gripper 3 and the follower gripper 4 are formed by the first injection molding. The blanks of the active gripper 3 and the follower gripper 4 are provided with pre-embedded grooves for embedding magnetic blocks. After the magnetic blocks are pressed into the pre-embedded grooves, the pre-embedded grooves are sealed by a secondary injection molding process. It should be noted that the magnetic blocks inside the active gripper 3 and the follower gripper 4 are opposite poles. Therefore, under normal conditions, the magnetic blocks can drive the active gripper 3 and the follower gripper 4 to close towards each other. By using magnetic attraction to drive the active gripper 3 and the follower gripper 4 to close towards each other, compared with the method of using springs, there is no need to consider the problem of spring fatigue, thereby effectively extending the service life.

[0025] The structure in which the active gripper 3 and the follower gripper 4 can separate in opposite directions is as follows: a drive arc block 11 is provided on the inner side of the bearing disk 1, and a coupling wheel 12 is provided at the tail end of the active gripper 3. By driving the bearing disk 1 to rotate, the coupling wheel 12 can be driven to gradually couple with the outer side of the drive arc block 11, thereby pushing the active gripper 3 and the follower gripper 4 to separate in opposite directions. After the coupling wheel 12 is disengaged from the drive arc block 11, the active gripper 3 and the follower gripper 4 can close together again under the action of the magnetic block.

[0026] In this embodiment, the structure for rotating the bearing disk 1 is as follows: a synchronous wheel 5 and a motor 6 are provided on the inner side of the bearing disk 1. There are multiple synchronous wheels 5, and a drive wheel 7 is provided at the output end of the motor 6. The drive wheel 7 and the synchronous wheels 5 are arranged in a fan shape. A transmission belt 9 is fitted around the outer periphery of the drive wheel 7 and the synchronous wheels 5. By pressing the transmission belt 9 tightly against the inner periphery of the bearing disk 1 on one side, the friction between the transmission belt 9 and the inner periphery of the bearing disk 1 can be increased under the action of pressure and the surface pattern of the transmission belt 9. Thus, the bearing disk 1 can be driven to rotate after the motor 6 is started. Furthermore, a guide wheel 10 is provided on the opposite side of the synchronous wheels 5. The guide wheel 10 has a coupling groove that couples with the inner side of the bearing disk 1, which can support the bearing disk 1 and improve the stability of the bearing disk 1 during rotation. By adopting the above structure, that is, installing the structure that drives the bearing disk 1 to rotate on the inner side of the bearing disk 1, the overall space occupied can be reduced, thereby making the overall structure more compact and easy to promote and use.

[0027] In this embodiment, active teeth 31 and driven teeth 41 are further provided on the opposing sides of the active gripper 3 and the driven gripper 4, respectively. The active teeth 31 and driven teeth 41 mesh with each other, so that when the active gripper 3 and the driven gripper 4 close together or separate away from each other, the meshing of the active teeth 31 and driven teeth 41 can stabilize the rotation trajectory of the active teeth 31 and driven teeth 41, and ensure the stability of the rotation of the active teeth 31 and driven teeth 41.

[0028] In this embodiment, an annular slide rail 15 is further provided below the bearing plate 1. The annular slide rail 15 is installed in the reserved slot of the machine tool. The bottom of the bearing plate 1 is provided with a connecting part 101. A slider 8 is provided on the connecting part 101. The slider 8 is coupled to the annular slide rail 15 and can form a sliding fit between the two. Through the sliding fit formed by the slider 8 and the annular slide rail 15 and the guiding fit formed by the guide wheel 10 on the bearing plate 1, the stability of the bearing plate 1 when rotating can be further improved.

[0029] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
