Description

Technical Field

[0001] The utility model relates to the technical field of filling equipment, in particular to a clamping mechanism of a filling machine. Background Art

[0002] When packaging and delivering fluid products, they are usually standardized by packaging after filling. The delivered products are bottled, barreled or bagged. In the process of assembly line operation, it is necessary to ensure the standard and efficiency of the filling operation, as well as the hygiene of the filled products, to avoid contamination during the filling process that affects the quality of the product.

[0003] Currently, the assembly line filling machines fill the containers below them through the filling nozzles. There is no auxiliary fixing structure between the filling nozzles and the containers. If the container shifts during the filling process, or the container and the filling nozzle are not aligned before the filling is started, it will cause leakage, waste or pollution.

[0004] It can be seen that the current filling structure still has room for improvement. It should be optimized and improved to improve the accuracy of filling, while ensuring the cleanliness of the filled products, reducing product contamination and improving product quality. Therefore, it is necessary to propose a more reasonable technical solution to solve the technical problems existing in the existing technology. Utility Model Content

[0005] To overcome at least one of the above-mentioned defects, the utility model proposes a clamping mechanism for a filling machine, which automatically clamps and holds the container mouth to achieve alignment with the filling nozzle, thereby ensuring the accuracy of filling and avoiding leakage or contamination of the product.

[0006] In order to achieve the above purpose, the clamping mechanism disclosed in the utility model can adopt the following technical solutions:

[0007] A filling machine clamping mechanism comprises a control body, a relatively open and closed clamping arm is arranged inside the control body, and a driving structure for driving the clamping arm to switch between a clamping position and a loosening position is arranged inside the control body; the control body cooperates with an installation body and slides relatively in the vertical direction, and a filling head is also arranged on the installation body, and the filling head descends or rises synchronously with the installation body.

[0008] In the above disclosed clamping mechanism, the clamping arm clamps or releases the container mouth under the control of the control body, and filling is performed in the clamping state to ensure the reliability and safety of filling, and the container can be transported in the release state for continuous filling.

[0009] Furthermore, in the present invention, the clamping arm can be arranged in a variety of forms, which are not limited to the only one. Here, an optimization is made and one feasible option is proposed: the clamping arm is hinged with the control body and deflects relative to the control body, and the driving structure includes a reciprocating driving structure and drives the clamping arm to deflect. When such a solution is adopted, the reciprocating driving structure includes a piston driving structure, a telescopic electromagnet, a crankshaft connecting rod and other mechanisms.

[0010] Furthermore, the structure of the clamping arm is optimized and one feasible option is proposed: the clamping arm includes a flip arm, the end of which is matched to the control body and deflected relative to the control body; the front end of the flip arm is provided with a detachable clamping block, and when the relative flip arm deflects to the clamping position, the clamping block is relatively close and used to clamp the container mouth. When such a solution is adopted, the clamping block on the flip arm can be replaced, and the appropriate clamping block can be selected according to the containers of different calibers, thereby improving the flexibility of the clamping mechanism.

[0011] Furthermore, the structure of the flip arm can also be constructed in various forms, which are not limited to the only one. Here, the structure of the flip arm is optimized and one feasible option is proposed: the flip arm includes a connecting arm section connected to the control body, and an extension arm section detachably arranged on the connecting arm section, and the clamping block is arranged on the extension arm section. When such a solution is adopted, the extension arm section can be replaced according to different container structures and clamping requirements, and a more compatible hijacking structure can be adopted, thereby improving the flexibility of the clamping mechanism.

[0012] Furthermore, the control body and the installation body are relatively lifted and lowered and the direction is limited to the vertical direction. The specific matching structure can adopt a variety of schemes, which are not limited to the only one. Here, we optimize and propose one of the feasible options: a number of guide structures are arranged between the control body and the installation body, and the guide structure includes a guide slide bar. The lower end of the guide slide bar is fixed relative to the control body, and the upper end is slidably matched with the installation body. The control body drives the guide slide bar to slide down to a low position under the action of gravity. The top of the guide slide bar is also provided with a baffle for limiting. When such a scheme is adopted, the guide slide bar can be a cylindrical rod or a polygonal prism rod.

[0013] Furthermore, in order to make the control body and the installation body cooperate more closely, an optimization is performed here and one feasible option is proposed: a sliding sleeve is provided on the installation body, and the sliding sleeve corresponds to the guide slide rod one by one and is slidably sleeved and cooperated.

[0014] Furthermore, the connection method between the control body and the guide slide bar can adopt a variety of structures, which are not limited to the only one. Here, an optimization is made and one feasible option is proposed: the control body is connected to a fixing block, and the lower end of the guide slide bar is connected and fixed to the fixing block. When such a solution is adopted, the fixing block can be integrally formed with the control body, or connected by a fastener.

[0015] Furthermore, in the present invention, the structure of the installation body is not limited to a single one, and it can be constructed in various forms. Here, an optimization is made and one of the feasible options is proposed: the installation body includes a mounting plate, and the mounting plate is connected and matched with the filling machine through a fastening structure. When such a solution is adopted, the fastening mechanism can be a threaded fastening structure, and the mounting plate is connected to the lifting frame of the filling machine, so that the lifting frame can drive the filling head to rise and fall.

[0016] Furthermore, in the present invention, the driving structure can adopt a variety of schemes, which are not limited to a single one. Here, optimization is performed and one feasible option is proposed: the driving structure includes a reciprocating driving member, which drives the clamping arm to deflect to the clamping position when the reciprocating driving member moves in the first direction, and drives the clamping arm to deflect to the loosening position when the reciprocating driving member moves in the second direction.

[0017] Furthermore, the action mode of the driving structure can also adopt a variety of schemes, which are not limited to the only one. Here, an optimization is made and one feasible option is proposed: the control body is provided with a first driving medium port and a second driving medium port, the first driving medium port is connected to the first cavity of the reciprocating driving member, and the second driving medium port is connected to the second cavity of the reciprocating driving member. When such a scheme is adopted, the driving medium can be gas or liquid.

[0018] Compared with the prior art, some beneficial effects of the technical solution disclosed in the utility model include:

[0019] By controlling the opening and closing action of the clamping arm to clamp or loosen the container mouth, the filling head can achieve more accurate and reliable filling operation, improve filling reliability and production efficiency, and avoid product contamination or leakage during the filling process.
