Description

TECHNICAL FIELD

[0002] With the development of domestic packaging industry, higher requirements are put forward to the quality, cost, packaging speed and applicability of packaging equipment. Among the feeding modes used in the field of automatic packaging machinery technology, three kinds of spiral, synchronous chain and magnetic suspension are commonly used. Among them, the spiral feeding mode needs to customize the spiral groove according to the product shape, and the adaptability to the product with complex shape is poor. Because of its working principle, it will cause friction to the product surface, and will damage the product surface with high appearance requirements and easy to damage; the working principle of synchronous chain feeding mode limits the production line speed and cannot meet the high-speed production; the cost of magnetic suspension feeding mode is high, which will cause the cost of packaging equipment to rise sharply, which is not conducive to popularization.

[0003] The prior art discloses a patent CN209113033U, which comprises a conveying module and two bottle separating modules. Each bottle separating module is provided with a first drive assembly, a second drive assembly, a driven member and a plurality of belts.

The rotational speed of the second drive assembly is higher than that of the first drive assembly. The driven member is arranged between the first drive assembly and the second drive assembly and is connected to the two drive assemblies by the plurality of belts. By means of the above technical features, the rotational speed difference between the two drive assemblies causes the connected belts to drive the bottles at different speeds, so that the bottles can be separated from each other when passing through, and a gap is formed between adjacent bottles. Therefore, the subsequent processing steps of the bottles can be carried out smoothly, thereby providing a two-stage belt bottle separating device.

[0004] With the use of the existing device including the above patent, the deficiencies of the technology have also been gradually exposed, mainly in the following aspects:

Detailed Implementation

[0031] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0032] like Figs. 1 to 3 As shown, a flexible adaptive bottle-shaped non-destructive fixed-distance bottle-splitting device includes a conveying platform 1, on both sides of the conveying platform 1, a plurality of bottle-clamping conveyor belts 4 are arranged side by side along the feeding direction.

[0033] The bottle-clamping conveyor belts 4 located on the same side are jointly mounted on the spacing adjustment frame 3. The two spacing adjustment frames 3 move towards and away from each other via a drive structure.

[0034] A laser displacement sensor 2 is fixedly connected to the conveying platform 1 near its material conveying start end, and a star wheel 10 is rotatably provided on the conveying platform 1 near its material conveying end end.

[0035] A photoelectric sensor 5 is fixedly installed on the spacing adjustment frame 3 for each bottle clamping conveyor belt 4.

[0036] The drive structure includes a rotating shaft 11 that is horizontally mounted on the conveying platform 1. Both ends of the rotating shaft 11 are coaxially provided with lead screws 12. The threads of the two lead screws 12 are arranged in opposite directions, and the two lead screws 12 are threadedly connected to two spacing adjustment frames 3.

[0037] A spacing adjustment motor 8 is fixedly connected to the side wall of one of the spacing adjustment frames 3, and the output shaft of the spacing adjustment motor 8 is fixedly connected to the end of the lead screw 12.

[0038] The conveying platform 1 is fixedly connected with two guide pillars 9 in parallel. The two ends of the guide pillars 9 penetrate the opposite side walls of the conveying platform 1. The spacing adjustment frame 3 is provided with guide holes that match the guide pillars 9.

[0039] The guide posts 9 are located on both sides of the rotating shaft 11.

[0040] A soft rubber layer is provided on the conveying surface of the bottle clamping conveyor belt 4.

[0041] The upper surface of the spacing adjustment frame 3 is rotatably equipped with three support wheels 7 that support the bottle clamping conveyor belt 4. The virtual connection lines of the three support wheels 7 are arranged in a triangle, and the bottle clamping conveyor belt 4 is rotated along the triangular trajectory. The conveying surfaces of two opposite bottle clamping conveyor belts 4 are parallel to each other.

[0042] The bottle clamping conveyor belt 4 is a synchronous belt, and the support wheel 7 is a synchronous wheel that matches the synchronous belt.

[0043] A drive motor 6 is fixedly connected to the lower end of the spacing adjustment frame 3, and the output shaft of the drive motor 6 is fixedly connected to one of the support wheels 7.

[0044] The innovation of this device lies in its structure. The circuits and PLC program control involved are common knowledge to those skilled in the art and are not part of the innovation of this solution, so they will not be elaborated on here.

[0045] The working principle of this device is as follows:

[0046] Materials are conveyed by a conveyor line to a flexible feeding device (at this point, the materials are spaced out, but the spacing is inconsistent and disorderly). Before the product enters the bottle, the laser displacement sensor 2 detects the bottle width, and the spacing adjustment motor 8 adjusts the width between the clamping conveyor belts 4 to suit the bottle width. At the moment the product enters the clamping conveyor belt 4, the photoelectric sensor 5 detects the product position and calculates the difference between the phase of the product at this time and the phase corresponding to the 6 teeth of the end star wheel 10. The phase relationship is adjusted by the acceleration and deceleration of the product driven by several sets of drive motors 6. When the product flows to the end of each clamping conveyor belt 4, the speed of the clamping conveyor belt 4 is adjusted to be consistent with the conveyor line to ensure that the product transitions smoothly between the two sets of clamping conveyor belts 4. After the linkage control of several sets of clamping conveyor belts 4, the clamping conveyor belt 4 at the end clamps the product that has reached the feeding spacing requirement and accurately flows into the star wheel corresponding to the star wheel 10, completing the feeding action.
