Description

Technical Field

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

[0002] In industries such as food, pharmaceuticals, cosmetics, and chemicals, there is a high reliance on automated production lines to efficiently and accurately fill liquids, granules, or powders into various bottle-shaped containers. During this process, containers are typically continuously transported by conveyor belts, precisely positioned below the filling head, and briefly paused to complete the filling. However, due to the vibration of the conveyor belt, the differences in container shape, and the inertia of high-speed operation, misalignment between the bottle neck and the filling head can easily occur, leading to problems such as splashing, metering errors, and even container tipping. To ensure that the filling head can accurately and stably insert into the bottle neck, specialized fixtures must be used to reliably clamp and position the bottle at the moment of filling. This effectively improves filling accuracy, reduces material loss, avoids contamination, and ensures the continuity and stability of the production process.

[0003] Existing fixtures typically come with specific types of clamping blocks to hold bottles of a particular shape and size. However, in real-world multi-variety, small-batch production scenarios, when switching between different bottle types, operators must frequently disassemble the current clamping block and replace it with another type. This process is not only cumbersome and time-consuming, severely impacting production efficiency, but also causes wear on the threads of the mounting bolts and a decrease in the accuracy of the positioning surfaces due to repeated disassembly and assembly. This can lead to loosening or misalignment of the clamping blocks, ultimately affecting the stability of the clamping and the reliability of the filling process. Therefore, we propose a bottle filling fixture. Utility Model Content

[0004] The purpose of this invention is to provide a bottle filling and fixing fixture to solve the problem mentioned in the background art, where existing fixing fixtures are typically equipped with specific models of clamping blocks to accommodate bottles of a certain shape and size. However, in actual multi-variety, small-batch production scenarios, when switching between different bottle types, operators must frequently disassemble the current clamping block and replace it with another model. This process is not only cumbersome and time-consuming, severely impacting production efficiency, but also causes wear on the threads of the mounting bolts and a decrease in the accuracy of the positioning surface due to repeated disassembly and assembly, leading to loosening or misalignment of the clamping block, ultimately affecting the stability of the clamping and the reliability of the filling process.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 A bottle filling fixture includes a base 1, a movable frame 3 movably mounted on the top of the base 1, a rotating block 12 movably mounted inside the movable frame 3, clamping blocks 11 bolted around the rotating block 12, connecting columns 10 integrally fixedly mounted at the upper and lower ends of the rotating block 12, a connecting bearing 9 fixedly mounted at the end of the connecting column 10 away from the rotating block 12, a limit hole 15 opened inside the connecting column 10, a fixing frame 5 integrally fixedly mounted on the top of the movable frame 3, a limit movable square hole 6 opened at the top of the fixing frame 5, a limit post 4 passing through the limit movable square hole 6, a return spring 7 fixedly mounted at the top inside the fixing frame 5, and a limit ring 8 fixedly mounted at the bottom of the return spring 7.

[0022] In this implementation scheme: by setting a rotatable and adjustable rotating block 12, it is possible to adjust clamping blocks 11 of different shapes and sizes to the front end of the fixing fixture, so as to clamp and fix bottles of different shapes and sizes without frequent disassembly and assembly of clamping blocks 11. At the same time, the bolt-mounted clamping blocks 11 are easy to disassemble, so as to replace different models of clamping blocks 11 and avoid wear caused by frequent replacement.

[0023] Furthermore:

[0024] In an optional embodiment, the rotating block 12 is movably connected to the movable frame 3 via the connecting bearing 9 and the connecting column 10. The rotating block 12 rotates inside the movable frame 3 via the connecting bearing 9 and the connecting column 10. The rotating block 12 has a block-shaped structure.

[0025] In this implementation scheme: the above-mentioned technology enables the rotating block 12 to rotate smoothly inside the moving frame 3, thereby realizing the adjustment and switching of the clamping block 11.

[0026] Furthermore:

[0027] In an optional embodiment, the limiting post 4 has a quadrangular prism structure, and the length and width dimensions of the limiting post 4 match the length and width dimensions of the limiting movable square hole 6, so that the limiting post 4 can move inside the limiting movable square hole 6.

[0028] In this implementation scheme: the movable square hole 6 limits the quadrangular prism-shaped limiting post 4, so that the quadrangular prism-shaped limiting post 4 can only move up and down and cannot rotate.

[0029] Furthermore:

[0030] In an optional embodiment, the limiting post 4 passes through the interior of the reset spring 7 and the limiting ring 8 in sequence, the limiting post 4 is fixedly connected to the limiting ring 8, and the limiting post 4 is elastically connected to the fixing frame 5 through the reset spring 7 and the limiting ring 8.

[0031] In this implementation scheme: the elastic force of the return spring 7 always applies a downward force to the limiting ring 8 and the limiting post 4, so that the limiting post 4 is firmly inserted into the limiting hole 15.

[0032] Furthermore:

[0033] In an optional embodiment, the shape and size of the limiting hole 15 partially match the shape and size of the limiting post 4, and the shape and size of the limiting ring 8 are larger than the shape and size of the limiting hole 15.

[0034] In this implementation scheme: by inserting the limiting post 4 into the limiting hole 15, the adjusted rotating block 12 is fixed, thereby making the adjustment operation of the rotating block 12 simple and convenient.

[0035] Furthermore:

[0036] In an optional embodiment, the base 1 further includes:

[0037] The electric push rod 2 is fixedly installed on the left side of the base 1. The output end of the electric push rod 2 is keyed to the moving frame 3. The base 1 has a limit groove 14 inside. The limit slider 13 is movably installed inside the limit groove 14. The limit slider 13 is fixedly connected to the moving frame 3. The moving frame 3 moves on the base 1 through the electric push rod 2, the limit slider 13 and the limit groove 14.

[0038] In this implementation plan: the adjusted clamping blocks 11 are pushed by the above-mentioned technology, so that the two opposing clamping blocks 11 come closer to each other and close together, thus clamping and fixing the bottle.

[0039] Working principle: When using this bottle filling fixture, firstly, two identical fixtures are installed opposite each other on the filling equipment. Then, four clamping blocks 11 of different models are bolted to the perimeter of the rotating block 12. Next, the limiting post 4 is pulled upwards to move its bottom out of the limiting hole 15. The rotating block 12 is rotated to adjust the appropriate clamping block 11 to the front end of the fixture. The limiting post 4 is released, and the return spring 7 pushes the limiting ring 8 with its own elasticity, causing the limiting post 4 to move downwards and insert into the limiting hole 15 inside the connecting post 10, thus fixing the adjusted rotating block 12. Then, the bottle to be filled is placed between the two fixtures. The controller controls the electric push rod 2 to move the moving frame 3 a certain distance on the base 1, so that the two clamping blocks 11 close together to clamp and fix the bottle for filling. This is the working principle of the bottle filling fixture.
