Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic scale technology, specifically to an error-proof and traceable intelligent electronic scale. Background Technology
[0002] As people's living standards continue to improve, the quality requirements for products produced on a large scale are becoming increasingly stringent, especially with the limited use of food additives. This necessitates the use of electronic scales to weigh certain quantities of materials. However, due to the manual handling of materials and the large workload involved, it is easy to over- or under-weigh materials during the weighing process. Traditional systems for regulating the accuracy of material weighing are no longer sufficient to ensure that weighing errors are prevented. Problems with weighing can easily lead to unstable product quality or even product non-compliance. Traditional electronic scales can no longer meet the needs of modern industrial development, especially for food ingredients. Furthermore, the country now encourages traceability of materials in the food production process, and some regions have even mandated traceability of the food production process through local regulations.
[0003] In view of this, the inventors of this case conducted in-depth research on the above-mentioned problems, which led to the creation of this case. Utility Model Content
[0004] The purpose of this invention is to address the above-mentioned shortcomings by providing a traceable, error-proof intelligent electronic scale that offers high weighing accuracy, effectively guarantees weighing precision, and avoids weighing errors.
[0005] The solution adopted by this utility model to solve the technical problem is: an error-proof and traceable intelligent electronic scale, including a weighing frame, a weighing pan and several weighing sensors. The weighing frame is provided with a sensor bracket, and the several weighing sensors are all installed on the sensor bracket. The weighing pan is movably arranged on the weighing sensors. The weighing frame is provided with a material pouring mechanism for tilting the weighing pan to pour out the material when the weighing sensor value falls within a set value range.
[0006] Furthermore, in order to support the material on the weighing pan and ensure that the material is easy to pour, the upper side of the weighing pan is provided with a material trough for holding the material, and a discharge port is provided on one side of the material trough, and a discharge plate is rotatably installed on the discharge port.
[0007] Furthermore, to reduce the difficulty of dumping materials, the bottom of the trough is inclined downwards from the side away from the discharge port to the side closer to the discharge port so as to pour out the materials.
[0008] Furthermore, in order to achieve automatic material unloading and reduce the workload of workers, the unloading mechanism includes an unloading cylinder and a push rod. The unloading cylinder is installed on the weighing frame, one end of the push rod is connected to the cylinder rod of the unloading cylinder, and the other side of the push rod is provided with a ball joint. The lower side of the weighing pan facing away from the unloading port is provided with a slot for inserting the ball joint. When the cylinder rod of the cylinder extends, the ball joint moves into the slot, thereby causing the weighing pan to tilt and unload the material.
[0009] Furthermore, in order to control the operation of the unloading cylinder, the error-proof traceable smart electronic scale also includes a controller and a display screen. The load cell is connected to the controller to transmit the measured value to the controller. The controller is connected to the display screen to display the measured value of the load cell on the display screen. The controller is also connected to the unloading cylinder to drive the unloading cylinder to work and dump the material when the measured value of the load cell falls within the set value range.
[0010] Furthermore, in order to realize voice control of the electronic scale, the error-proof traceable smart electronic scale also includes a voice input module and a voice output module. The voice input module is connected to the controller to send commands to the controller via voice, and the controller is connected to the voice output module to control the voice output module to broadcast voice messages.
[0011] Furthermore, in order to reduce the workload of weighing materials, the error-proof traceable smart electronic scale also includes a formula storage module for storing product formula weight information. The controller is connected to the formula storage module to store or retrieve the formula weight information of each product.
[0012] Furthermore, in order to achieve traceability of material sources, the error-proof traceable smart electronic scale also includes a material storage module for storing material information, and the controller is connected to the material storage module to store or retrieve material information.
[0013] Compared with existing technologies, this utility model has the following advantages: This utility model is equipped with a material pouring mechanism. During use, the formula for the product to be made is retrieved. During production, a weighing sensor weighs the materials and sends the measured value to the controller. The controller compares the value measured by the weighing sensor with the ingredient weight information stored in the formula storage module. When the weighing sensor value falls within a set range, the pouring mechanism tilts the weighing pan to pour out the materials. If the weighing sensor value falls outside the set range, no material is poured until the worker adds or removes the materials to bring them within the set range. This effectively avoids large errors in the formula weight. This structure greatly reduces the workload of production personnel, achieving foolproof operation. Furthermore, the controller of this utility model can store weighing records, which can be retrieved for subsequent checks, enabling traceability of the production process and effectively ensuring food safety.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments:
[0019] Example: Figure 1-2 As shown, this embodiment provides an error-proof, traceable smart electronic scale, including a weighing frame 1, a weighing pan 2, and several weighing sensors 3. It also includes a voice input / scan input / manual input module and a password / fingerprint reader. The voice input / scan input / manual input module and the password / fingerprint reader are all connected to a controller to ensure authorized use, protect information security, and ensure information accuracy and security. The weighing frame is provided with a sensor bracket 4, and several weighing sensors 3 are all mounted on the sensor bracket 4. The weighing pan 2 is movably mounted on the weighing sensors 3. The weighing frame is provided with a material pouring mechanism for tilting the weighing pan 2 to pour out materials when the value of the weighing sensor 3 falls within a set value range.
[0020] In this embodiment, in order to support the material on the weighing pan 2 and ensure that the material is easy to pour, the upper side of the weighing pan 2 is provided with a recessed material trough 201 for holding the material. A discharge port is provided on one side of the material trough 201, and a discharge plate 5 is rotatably mounted on the discharge port. A torsion spring is provided between the discharge plate 5 and the weighing pan 2 to keep the discharge plate 5 in contact with the weighing pan 2, thereby keeping the discharge port closed. The weighing pan 2 is also provided with a mechanism to push the discharge plate 5 downwards against the force of the torsion spring. A push cylinder 7 for opening the discharge port is installed on the weighing pan 2. The cylinder rod of the push cylinder 7 abuts against the discharge plate 5. A control switch for controlling the operation of the push cylinder 7 is provided in the ball groove. When the cylinder drives the ball joint to insert into the ball groove, the ball joint touches the control switch, which controls the push cylinder 7 to work, lowering the discharge plate 5 and opening the discharge port. When the ball joint leaves the ball groove, the push cylinder 7 stops working, and the discharge plate 5 closes the discharge port again under the action of the torsion spring.
[0021] In this embodiment, in order to reduce the difficulty of dumping materials, the bottom of the material trough 201 is inclined downward from the side away from the discharge port to the side closer to the discharge port so as to dump the materials.
[0022] In this embodiment, in order to realize automatic material unloading and reduce the workload of workers, the unloading mechanism includes an unloading cylinder and a push rod 6. The unloading cylinder is installed on the weighing frame. One end of the push rod 6 is connected to the cylinder rod of the unloading cylinder. The other side of the push rod 6 is provided with a ball joint. The lower side of the weighing pan 2 facing away from the unloading port is provided with a slot 202 for inserting the ball joint. When the cylinder rod of the cylinder extends, the ball joint moves into the slot 202, thereby causing the weighing pan 2 to tilt and unload the material.
[0023] In this embodiment, to control the operation of the unloading cylinder, the error-proof traceable smart electronic scale also includes a controller and a display screen. The weighing sensor 3 is connected to the controller to transmit the measured value to the controller. The controller is connected to the display screen to display the measured value of the weighing sensor 3 on the display screen. The controller is also connected to the unloading cylinder to drive the unloading cylinder to work and pour the material when the measured value of the weighing sensor 3 falls within the set value range, ensuring accurate weighing without "errors". At the same time, the weighing value is stored in a set location and can be connected to a computer or USB flash drive to output information for easy retrieval and traceability.
[0024] In this embodiment, in order to realize voice control of the electronic scale, the error-proof traceable smart electronic scale also includes a voice input module and a voice output module. The voice input module is connected to the controller to send commands to the controller via voice. The controller is connected to the voice output module to control the voice output module to broadcast voice messages to confirm that the requirements are met and ensure the accuracy of the materials. Then the electronic scale enters the weighing state.
[0025] In this embodiment, in order to reduce the workload of weighing materials, the error-proof traceable smart electronic scale also includes a formula storage module for storing product formula weight information. The controller is connected to the formula storage module to store or retrieve the formula weight information of each product.
[0026] In this embodiment, in order to achieve traceability of material sources, the error-proof traceable smart electronic scale also includes a material storage module for storing material information (material name, batch or production date and weighing record). The controller is connected to the material storage module so that when the record is viewed, the material information and the corresponding weighing record can be retrieved to achieve traceability.
[0027] This invention features a material-pouring mechanism. During use, the formula for the product to be manufactured is retrieved. During production, a weighing sensor 3 weighs the materials and sends the measured value to the controller. The controller compares the value measured by the weighing sensor 3 with the weight of the ingredients stored in the formula storage module. When the value measured by the weighing sensor 3 falls within a set range, the material-pouring mechanism tilts the weighing pan 2 to pour out the materials. If the value measured by the weighing sensor 3 falls outside the set range, no material is poured until the operator adjusts the material to within the set range. This effectively avoids large errors in the formula weight. This structure significantly reduces the workload of production personnel, achieving foolproof operation. Furthermore, the controller of this invention can store weighing records, which can be retrieved for subsequent checks, enabling traceability of the production process and effectively ensuring food safety.
[0028] The above description is merely an embodiment of this utility model and does not limit the scope of patent protection of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this utility model.
