[0001] This invention relates to the field of automated production technology, specifically to a fully automated mixing, filling, and tableting system. Background Technology

[0002] In the production process, material mixing, filling, and tableting are key steps that directly affect product quality and production efficiency. Currently, existing technologies mostly use segmented manual operation or semi-automated equipment to complete these processes, which presents the following problems: High manual involvement: Manual handling of material proportioning, weighing, transfer, feeding, and equipment start-up and shutdown is required, which is not only labor-intensive but also prone to insufficient material proportioning accuracy due to human error, affecting product quality stability; Low production efficiency: There is a lack of efficient linkage between processes, and the transfer of materials between processes is time-consuming, requiring waiting for the previous process to be completed before starting the next process, making continuous production impossible; Low automation: Existing semi-automated equipment requires manual monitoring of the status of each process and timely handling of abnormalities in equipment operation. If a fault is not detected in time, it can easily lead to production interruption or the production of batches of defective products; High cost: Labor costs are rising year by year, segmented production models require multiple positions, and material waste and rework of defective products due to operational errors further increase production costs.

[0003] Based on this, the present invention designs a fully automatic mixing, filling, and tableting system to solve the above problems. Summary of the Invention

The tablet pressing system includes a pressure hydraulic rod, the output end of which is fixedly connected to a tablet, and the pressure hydraulic rod corresponds one-to-one with the mold.

[0006] When the fault monitoring module detects an abnormal operation of a component, it sends a signal to the controller, which then controls the system to stop operating and displays the fault information through the HMI (Human-Machine Interface).

[0018] Please see Figures 1-4 The present invention provides a technical solution: a fully automatic mixing, filling, and tableting system, including a mixing system 1, a filling system 2, a tableting system 3, and a fault monitoring system 4 for detecting the above systems; each module achieves signal linkage through the controller; The mixing system includes: a material storage module 5 and a mixing module 6; The storage module 5 includes a storage bin 7, a conveyor belt 8 is arranged below the storage bin 7, a mixing module 6 is arranged in the transmission direction of the conveyor belt 8, and a load-bearing tray 9 is arranged between the conveyor belt 8 and the mixing module 6.

The tablet pressing system 3 includes a pressure hydraulic rod 15, and the output end of the pressure hydraulic rod 15 is fixedly connected to a tablet 16. The pressure hydraulic rod 15 corresponds one-to-one with the mold 14.

[0019] When the fault monitoring module 4 detects an abnormal operation of a component, it sends a signal to the controller, which then controls the system to stop operating and displays the fault information through the HMI 17 human-machine interface.

[0020] As a further embodiment of the present invention, the storage bin 7 can be configured with multiple compartments, the number of which can be adjusted according to the type of ingredients.

[0021] As a further embodiment of the present invention, the stirring time of the stirring chamber 10, the downward pressure and holding time of the hydraulic rod 15, and the number of rotations of the scraper 13 of the packing system 2 can all be adjusted and set through the HMI 17 human-machine interface.

[0022] As a further aspect of the present invention, the gap between the scraper 13 and the disc worktable 12 is at the micrometer level, and the cavity size of the mold 14 can be designed and adjusted according to product requirements.

[0023] As a further embodiment of the present invention, a proximity switch is installed at the feed inlet of the mixing chamber 10. When the light on the proximity switch is on, the signal is activated, the feed inlet valve of the mixing chamber 10 is opened, and material is started to be discharged. When the proximity switch light goes out, the signal is disconnected.

[0024] As a further embodiment of the present invention, in the stirring module 1, the load-bearing tray 9 is moved by the drive motor.

[0025] As a further embodiment of the present invention, the mixing motor 11 is started 5 seconds after the inlet valve of the mixing chamber 10 is closed, and the outlet valve of the mixing chamber 10 is opened 3 seconds after the mixing motor 11 stops.

[0026] As a further embodiment of the present invention, the mold 14 contains a demolding hydraulic rod to demold the pressed diaphragm until it is completely removed, at which point the demolding hydraulic rod descends to its initial position.

[0027] Working principle: The system has a storage bin 7 at the front end. Each ingredient is stored in a small compartment of the storage bin 7. An electric valve is installed at the discharge port of the storage bin 7. Each small compartment inside the storage bin 7 is equipped with a weighing sensor. When the material in each small compartment of the storage bin 7 reaches the set value of the weighing sensor, the electric valve at the discharge port of the storage bin 7 opens, and the material is transported to the mixing system by the conveyor belt.

[0028] Mixing System 1: A weight sensor is installed in Mixing System 1 at the bottom of the support tray 9. After setting the parameters and placing the required materials, the system is programmed in the control system. When the system starts, the control system transmits a signal to the valve controlled by the on / off switch of the feed inlet (the number of feed inlets can be increased for mixing multiple materials). The feed inlet opens, and the material reaches the support tray 9. When the weight of the material reaches the set parameter, the weight sensor transmits a signal to the controller. The controller performs logic calculations and transmits the signal to the drive motor. The drive motor moves the support tray 9. When the set mixing parameters are reached, it is considered one batch. The support tray 9 passes through a proximity switch, which transmits a signal to the controller. The controller performs logic calculations and transmits the signal to the valve controlled by the on / off switch of the feed inlet. The feed inlet opens, and the material reaches the support tray. This process is repeated to sort the materials.

[0029] Each sorted batch of material is conveyed to the mixing chamber 10 via a conveyor belt. A proximity switch is installed at the inlet of the mixing chamber 10. When the light illuminates, the signal is activated, the inlet valve of the mixing chamber 10 opens, and material feeding begins. When the proximity switch light goes out, the signal is disconnected, and the controller transmits a signal to the inlet valve of the mixing chamber 10, causing the inlet valve to close. The program is set to wait 5 seconds after the inlet valve of the mixing chamber 10 closes before the controller transmits a signal to the motor in the mixing chamber 10, and the timer starts counting down to begin mixing. The mixing time can be set via HMI17. Once the set mixing time is reached, the controller transmits a signal to the motor in the mixing chamber 10, and the mixing motor 11 in the mixing chamber 10 stops. After waiting 3 seconds, the controller transmits a signal to the outlet valve of the mixing chamber 10, and the outlet valve opens. The controller then transmits a signal to the conveyor belt 8, and the mixed material is conveyed to the filling system via the conveyor belt 8.

[0030] Packing System 2: The packing system molds are arranged in a circle around the center on the disc worktable 12. The scraper 13 rotates around the disc worktable 12, and the gap between the scraper 13 and the disc worktable 12 is at the micron level. When the mixed material comes into contact with a proximity switch, the signal is transmitted to the controller. The controller performs logic calculations and transmits the signal to the electric valve at the inlet of the packing system. The door at the inlet of the packing system opens, allowing the set amount of mixed material to enter. The weighing sensor transmits the signal to the controller, which performs logic calculations and transmits the signal to the electric valve at the inlet of the packing system. The door at the inlet of the packing system closes. There are 6 molds 14 at this location (these are custom molds and can be designed according to requirements). The packing system molds 14 are arranged in a circle around the center on the disc worktable 12. With the door at the inlet of the packing system closed, the scraper 13 begins to rotate, and the mixed material enters the molds 14. The scraper 13 rotates 3 times (the number of rotations can be set).

[0031] Tableting System 3: The tableting system 3 includes a pressure hydraulic rod 15, 6 hydraulic rods, etc. The scraper 13 rotates 3 times (the number of rotations can be set). After the set number of rotations is reached, a signal is transmitted to the controller. The controller performs logic calculations and transmits the signal to the hydraulic system. The hydraulic system starts working, and the pressure hydraulic rod 15 descends to press the material in the mold 14. The pressing parameters can be set. After reaching the set pressing parameters, pressure is maintained (the holding time can be set). After the holding time is completed, the pressure hydraulic rod 15 rises. There is a demolding hydraulic rod in the mold 14 to demold the pressed tablet. After all the tablets are demolded, the demolding hydraulic rod descends to the initial position, the disc starts to rotate, and the tablets are conveyed to the designated position at the outlet.

[0032] Fault monitoring system: Real-time monitoring of the status of electric valves, load cells, and proximity switches. If an abnormality occurs, the electric valves, load cells, and proximity switches will transmit signals to the controller. The controller will perform logic calculations and transmit the signals to the electric valves, load cells, proximity switches, etc., and the system will stop immediately. The fault point can be reset.
