Description

Technical Field

[0001] This utility model relates to the field of composite flame retardant production technology, specifically to a feeding device for producing composite flame retardants. Background Technology

[0002] Flame retardants are substances used to improve the fire resistance of materials, that is, additives that prevent materials from being burned and inhibit the spread of flames. They are widely used in the flame retardancy of synthetic and natural polymer materials. Commonly used flame retardants can be classified into halogen-based, phosphorus-based, nitrogen-based, and boron-based according to the flame retardant elements they contain. In the process of flame retardant processing, a feeding device is required.

[0003] Traditional feeding methods rely heavily on manual operation or simple mechanical pouring, which is not only inefficient but also lacks accurate weighing, leading to frequent weighing deviations. These deviations can cause imbalances in the formulation ratios, affecting batch-to-batch consistency and, in severe cases, resulting in substandard performance of the entire batch of products. This leads to raw material waste and increased production costs. Therefore, a feeding device for producing composite flame retardants is needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a feeding device for producing composite flame retardants, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A feeding device for producing composite flame retardants includes a feeding box, a weighing component, and a driving component. The feeding box has a conveying pipe at its bottom end, and a metering bin at one bottom end of the conveying pipe. The weighing component includes a first placement plate and a second placement plate. Load sensors are provided on the top of both the first and second placement plates, and a weighing pan is provided on the top of each load sensor. Two bearings are provided on each side of the metering bin. A first rotating rod is provided at one end of each side of the first placement plate, and a second rotating rod is provided at one end of each side of the second placement plate. The two first rotating rods and the two second rotating rods are respectively disposed between two opposing bearings. A control panel is provided on one side of the metering bin, and the load sensors are electrically connected to the control panel.

[0006] As a preferred embodiment of this utility model, the driving assembly includes a second driving source and two second bearing seats. A T-shaped support plate is provided on one side of the quantitative chamber. The T-shaped support plate provides a stable mounting base for the second driving source. The second driving source is installed on one side of the vertical plate of the T-shaped support plate. The output end of the second driving source is connected to the first rotating rod. The second driving source is a motor that provides power to drive the rotating rod to rotate, thereby causing the entire weighing assembly to flip.

[0007] In this embodiment, two second bearing seats are disposed on one side of the metering chamber, and a rotating shaft is provided on the two second bearing seats. One end of the rotating shaft is provided with a first driven bevel gear, and one end of the first rotating rod is provided with a first driving bevel gear. The first driving bevel gear meshes with the first driven bevel gear, and the first driving bevel gear transmits the power generated by the second drive source to the first driven bevel gear, so that the rotating shaft rotates.

[0008] In this embodiment, a second driving bevel gear is provided at the other end of the rotating shaft, and a second driven bevel gear is provided at one end of a second rotating rod. The second driven bevel gear meshes with the second driving bevel gear. The rotation of the rotating shaft drives the second driving bevel gear to rotate and transmits power to the second driven bevel gear, causing the second rotating rod to rotate.

[0009] In this embodiment, protective covers are provided on the exterior of the first driven bevel gear and the first driving bevel gear, as well as on the exterior of the second driving bevel gear and the second driven bevel gear. The protective covers cover the exposed bevel gears to prevent operators from contacting the high-speed rotating gears, and at the same time prevent flame retardant dust from entering the gear meshing area, thereby avoiding wear and failure and extending the equipment life.

[0010] In this embodiment, the second drive source is electrically connected to the control panel, and the control panel controls the second drive source to work when the weight reaches a set value.

[0011] In this embodiment, the conveying pipe is equipped with a spiral conveying roller inside, which connects the feeding box and the metering bin. Through the rotation of the spiral conveying roller, the powdered or granular flame retardant is stably and controllably conveyed from the feeding box to the metering bin. One end of the conveying pipe is equipped with a first driving source, the output end of which is connected to the spiral conveying roller. The first driving source is a motor, which provides power to the spiral conveying roller.

[0012] In this embodiment, the two ends of the conveying pipe are respectively provided with first bearing seats, and the two ends of the spiral conveying roller are respectively set on the two first bearing seats. The first bearing seats provide stable rotational support for the two ends of the spiral conveying roller, ensuring smooth rotation, reducing friction and vibration, thereby ensuring the stability of the conveying process.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. In this invention, by setting up an independent weighing component and directly using a high-sensitivity load sensor to support the weighing pan, the weight of the material can be measured in real time and accurately. This weighing component is electrically connected to the control panel, forming a closed-loop weighing control system that effectively avoids human error and mechanical interference, ensuring that the amount of material added each time strictly conforms to the preset formula requirements. This fundamentally solves the pain point of inaccurate weighing in traditional methods, providing a core guarantee for the consistency and stability of the performance of composite flame retardant products.

[0014] 2. In this invention, a second drive source drives a rotating rod, causing the entire placement plate, along with the weighing pan, to flip under the support of bearings. This near-tilting unloading method utilizes gravity to completely empty the material, which is particularly effective for easily adhering powder materials. It effectively solves the historical problem of material residue in the quantitative silo, ensuring not only the accuracy of single feeding but also preventing cross-contamination between different batches of raw materials, thus ensuring product purity and quality.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and complete.

[0019] For examples, please refer to Figure 1-4 This utility model provides a technical solution: A feeding device for producing composite flame retardants includes a feeding box 1, a weighing assembly 4, and a driving assembly 5. The feeding box 1 serves as the "raw material bin" of the device, storing the composite flame retardant raw materials to be fed, providing a stable material source for subsequent quantitative conveying. A conveying pipe 2 is located at the bottom of the feeding box 1, and a quantitative bin 3 is located at one end of the bottom of the conveying pipe 2. The quantitative bin 3 is the "workshop" for precise weighing, providing the installation foundation and structural support for the entire weighing assembly 4. The weighing assembly 4 includes a first placement plate 401 and a second placement plate 405. Load sensors 403 are located on the top of both the first placement plate 401 and the second placement plate 405. The load sensors 403 are the core sensing elements, detecting the weight of the quantitative bin 3 and its internal materials in real time, converting the weight signal of the materials into an electrical signal, and are the cornerstone for achieving high-precision quantitative weighing. The top of the load sensor 403 is equipped with a weighing pan 404, which directly supports the material and completely transfers the weight of the material to the load sensor 403 below. Two bearings 301 are respectively provided on both sides of the metering chamber 3. One rotating rod 402 is provided at one end of each side of the first placement plate 401, and a second rotating rod 406 is provided at one end of each side of the second placement plate 405. The two first rotating rods 402 and the two second rotating rods 406 are respectively arranged between the two opposing bearings 301. The bearings 301 rotatably connect the first placement plate 401 and the second placement plate 405 to the side wall of the metering chamber 3. A control panel 6 is provided on one side of the metering chamber 3. The load sensor 403 is electrically connected to the control panel 6. The control panel 6 acts as the "brain" of the entire device and receives the weight signal from the load sensor 403.

[0020] In this embodiment, the drive assembly 5 includes a second drive source 501 and two second bearing seats 503. A T-shaped support plate 302 is provided on one side of the quantitative chamber 3. The T-shaped support plate 302 provides a stable mounting base for the second drive source 501. The second drive source 501 is installed on one side of the vertical plate of the T-shaped support plate 302. The output end of the second drive source 501 is connected to the first rotating rod 402. The second drive source 501 is a motor that provides power to drive the rotating rod to rotate, thereby causing the entire weighing assembly 4 to flip.

[0021] In this embodiment, two second bearing seats 503 are disposed on one side of the metering chamber 3. A rotating shaft 504 is provided on the two second bearing seats 503. A first driven bevel gear 505 is provided at one end of the rotating shaft 504, and a first driving bevel gear 502 is provided at one end of the first rotating rod 402. The first driving bevel gear 502 meshes with the first driven bevel gear 505. The first driving bevel gear 502 transmits the power generated by the second drive source 501 to the first driven bevel gear 505, so that the rotating shaft 504 rotates.

[0022] In this embodiment, the other end of the rotating shaft 504 is provided with a second driving bevel gear 506, and one end of a second rotating rod 406 is provided with a second driven bevel gear 507. The second driven bevel gear 507 meshes with the second driving bevel gear 506. The rotation of the rotating shaft 504 drives the second driving bevel gear 506 to rotate and transmits power to the second driven bevel gear 507, so that the second rotating rod 406 rotates.

[0023] In this embodiment, protective covers 7 are provided on the exterior of the first driven bevel gear 505 and the first driving bevel gear 502, as well as on the exterior of the second driving bevel gear 506 and the second driven bevel gear 507. The protective covers 7 cover the exposed bevel gears to prevent operators from contacting the high-speed rotating gears, prevent flame retardant dust from entering the gear meshing area, avoid wear and failure, and extend the equipment life.

[0024] In this embodiment, the second drive source 501 is electrically connected to the control panel 6, and the control panel 6 controls the second drive source 501 to work when the weight reaches a set value.

[0025] In this embodiment, the conveying pipe 2 is equipped with a spiral conveying roller 202, which connects the feeding box 1 and the metering bin 3. Through the rotation of the spiral conveying roller 202, the powdered or granular flame retardant is stably and controllably conveyed from the feeding box 1 to the metering bin 3. One end of the conveying pipe 2 is equipped with a first driving source 201, and the output end of the first driving source 201 is connected to the spiral conveying roller 202. The first driving source 201 is a motor that provides power to the spiral conveying roller 202.

[0026] In this embodiment, the two ends of the conveying pipe 2 are respectively provided with first bearing seats 203, and the two ends of the spiral conveying roller 202 are respectively set on the two first bearing seats 203. The first bearing seats 203 provide stable rotational support for the two ends of the spiral conveying roller 202, ensuring smooth rotation, reducing friction and vibration, thereby ensuring the stability of the conveying process.

[0027] The working process of this utility model is as follows: When the feeding device and structure designed in this scheme for producing composite flame retardants are in operation, the operator sets the weight of material to be fed on the control panel 6. The control panel 6 then activates the first drive source 201, and the motor drives the spiral conveying roller 202 to rotate inside the conveying pipe 2. The flame retardant material in the feeding box 1 is pushed by the spiral blades and stably and continuously fed into the quantitative bin 3 below.

[0028] As material enters the metering bin 3, load sensors 403 installed on the first placement plate 401 and the second placement plate 405 are monitoring the total weight of the metering bin 3 and its contents in real time. This weight data is transmitted to the control panel 6 in real time, which compares the real-time weight with a preset value. When the weight reaches or is very close to the preset value, the control panel 6 immediately sends a signal to the first drive source 201 to stop the conveying.

[0029] After feeding stops, the control panel 6 activates the second drive source 501. The output shaft of the second drive source 501 directly drives the first rotating rod 402 to rotate. The first driving bevel gear 502 at one end of the first rotating rod 402 meshes with the first driven bevel gear 505 mounted on the rotating shaft 504, changing the direction of power by 90 degrees and transmitting it to the rotating shaft 504. The second driving bevel gear 506 at the other end of the rotating shaft 504 meshes with the second driven bevel gear 507 on another second rotating rod 406, changing the direction of power by 90 degrees again and driving the second rotating rod 406 to rotate. Under the synchronous rotation of the first rotating rod 402 and the second rotating rod 406, the weighing component 4 is driven to flip, thoroughly and quickly pouring the precisely weighed material inside into the downstream production equipment.

[0030] The first drive source 201, the second drive source 501, and the control panel used in this utility model are all existing known electrical devices, and all can be purchased and used directly on the market. Their structure, circuit, and control principle are all existing known technologies. Therefore, the structure, circuit, and control principle of the first drive source 201, the second drive source 501, and the control panel will not be described in detail here.

[0031] All standard parts used in this application can be purchased from the market. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art and are also general components, which are common knowledge in this field.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
