Description

Technical Field

[0001] This application relates to the field of food packaging equipment technology, specifically to an automatic packaging system for multi-material flower tea. Background Technology

[0002] Scented tea, especially blended scented tea containing various materials (such as tea leaves, jujubes, longans, goji berries, chrysanthemums, etc.), has a more complex packaging process due to the potential for uneven size, shape, and density among the materials.

[0003] Traditional packaging methods rely heavily on manual weighing, proportioning, and filling, resulting in low efficiency, high labor costs, difficulty in ensuring hygiene, and susceptibility to human error, leading to poor product consistency. Existing automated packaging equipment is typically designed for single or similar-shaped materials. For multi-material flower teas that need to process both regular small particles (such as goji berries) and irregular large particles (such as dates and longans), the limited measurement methods also present challenges. Either all methods rely on weighing, but for materials that need to be measured by the "piece" (such as dates), weighing cannot guarantee consistent quantities in each bag, affecting product appearance and consumer experience; or all methods rely on counting, but for small, lightweight materials (such as tea leaves), counting is inefficient and uneconomical. Furthermore, the process is cumbersome, requiring multiple independent weighing and conveying stations for various materials, resulting in a large system footprint, long material flow paths, and a high risk of material damage or cross-contamination.

[0004] Therefore, there is an urgent need in this field for a device that can efficiently, accurately, and automatically complete the mixing and packaging of materials in multiple forms. Utility Model Content

[0005] This application provides an automatic packaging system for multi-material flower tea, which solves the problem that existing automated packaging equipment is usually only designed for single or similar materials. For multi-material flower tea that needs to process both regular small particles (such as goji berries) and irregular large particles (such as jujubes and longans), there is a problem of single metering method, and the process flow is cumbersome. Multiple materials need to go through multiple independent weighing and conveying stations. The system occupies a large area, the material flow path is long, and it is easy to cause material damage or cross-contamination.

[0006] This application provides an automatic packaging system for multi-material flower tea, including a controller and a support frame. The support frame includes a first support frame and a second support frame. A weighing mechanism is provided on the first support frame. The weighing mechanism includes multiple weighing heads.

Detailed Implementation

[0015] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0016] The core of this application is to provide an automatic packaging system for multi-material flower tea. This system solves the problem that existing automated packaging equipment is usually designed only for single or similar materials. For multi-material flower tea that needs to process both regular small particles (such as goji berries) and irregular large particles (such as jujubes and longans), there is a problem of a single metering method and a complicated process flow. Multiple materials need to go through multiple independent weighing and conveying stations, the system occupies a large area, the material flow path is long, and it is easy to cause material damage or cross-contamination.

[0017] like Figures 1-2As shown, this application provides an automatic packaging system for multi-material flower tea, including a controller and a support frame. The controller can be a PLC module. The PLC module controls each component through signal interaction with the components it is electrically connected to. The signal interaction between the PLC module and the components is a prior art that is easily conceived by those skilled in the art and is not the focus of this application, so it will not be described in detail here. The support frame includes a first support frame 101 and a second support frame 201. A weighing mechanism is provided on the first support frame 101. The first support frame 101 is used to fix and support the weighing mechanism. The weighing mechanism is a rotary weighing machine. The weighing mechanism is mainly used to process materials suitable for weighing by weight. The weighing mechanism includes multiple weighing heads 100. The controller is electrically connected to each weighing head 100. Each weighing head 100 can be configured with different materials (e.g., goji berries, rose petals, chrysanthemums, rock sugar, etc.) and weighs them synchronously and in parallel according to the weight value preset by the control system. A conveyor 300 is installed at the discharge port of the weighing mechanism. Hoppers 301 are evenly arranged on the conveyor 300. The conveyor 300 consists of a drive motor, a chain, and multiple hoppers 301 evenly fixed on the chain. The hoppers 301 are used to receive materials from the weighing head 100 and the counting machine 200. Above the conveyor 300, a counting mechanism is also installed on one side of the weighing mechanism. The counting mechanism includes two counting machines 200 located on a second support frame 201. The counting machines 200 can be photoelectric counting machines, used to process jujubes, longans, etc., measured by quantity. The operating speed of the conveyor 300 is matched to the operating frequency of each feeding station, ensuring that each hopper 301 has sufficient time to receive all the predetermined materials without spillage. A packaging machine 500 is installed at the discharge end of the conveyor 300. The conveyor 300, the weighing mechanism, and the counting mechanism are all electrically connected to a controller. The material received in the hopper 301 is conveyed to the packaging machine 500 by the conveyor 300. The packaging machine 500 forms the material into individual flower tea packaging bags. Specifically, the structure and working principle of the packaging machine 500 can be found in the prior art, and will not be described in detail here.

[0018] In the above embodiments, preferably, the number of the plurality of weighing heads 100 is six. In actual use, the six weighing heads 100 can work simultaneously, and the weighed materials are sequentially placed into the hopper 301 below them in a preset order.

[0019] To prevent machine downtime caused by malfunctions of the weighing head 100 or the counting machine 200, preferably, a manual inspection station 400 is also provided between the packaging machine 500 and the counting mechanism. Workers can perform preliminary inspections and add materials at the manual inspection station 400, which reduces the increase in product defect rate due to machine malfunctions.

[0020] Furthermore, the discharge end of the packaging machine 500 is connected to a re-inspection component 700 via an output inclined belt 600. The re-inspection component 700 distinguishes between defective and qualified products. Preferably, the re-inspection component 700 includes a sorting conveyor belt 701, a re-inspection scale 702, and a rejection component. The rejection component includes a cylinder 703 disposed on one side of the re-inspection scale 702. A push plate 704 is fixed to the piston rod of the cylinder 703, and the movement direction of the piston rod is perpendicular to the conveying direction of the sorting conveyor belt 701. The re-inspection scale 702 dynamically weighs the actual weight of each finished packaging bag and feeds the data back to the controller. The controller compares the actual weight with a preset acceptable weight range (upper and lower limits) and outputs a control signal. Qualified finished bags are conveyed to the unloading area for boxing, while unqualified finished bags are rejected from the conveyor line by the push plate 704 driven by the cylinder 703.

[0021] To facilitate the feeding of materials into the weighing mechanism, preferably, a ladder 800 is provided on the side of the weighing mechanism away from the counting mechanism, and the ladder 800 also facilitates the observation of the material in the weighing hopper.

[0022] The automatic packaging system for multi-material flower tea provided in this application works as follows: The controller controls the hopper 301 of the conveyor 300 to pass under the weighing head 100 and receive goji berries, rose petals, chrysanthemums and rock sugar in sequence. Then, the controller controls the hopper 301 to move to the bottom of the counting machine 200 and receive two jujubes and two longans. After all the materials are collected in the hopper 301, the conveyor 300 transports the materials to the packaging machine 500 to make flower tea packaging bags. The finished bags are transported by the output inclined belt 600 to the sorting conveyor belt 701. Qualified finished bags are transported to the unloading area for boxing, while unqualified finished bags are removed from the conveyor line by the push plate 704 driven by the cylinder 703.
