Description

Technical Field

[0001] This utility model relates to the technical field of fire-retardant coating production equipment, and in particular to a metering device for fire-retardant coating raw materials. Background Technology

[0002] In many fields such as construction, power, and transportation today, fire-retardant coatings are a key fire safety material. Their quality is directly related to people's lives and property safety as well as the fire resistance performance of various facilities. The stability of the quality of fire-retardant coatings depends on the accuracy of raw material measurement during the production process.

Operators use experience and simple weighing tools for measurement, which is not only inefficient but also highly susceptible to human factors, leading to significant measurement errors. Furthermore, traditional fire-retardant coating raw material measurement often suffers from unstable and discontinuous feeding speeds during the raw material transportation process, making it difficult to meet the needs of different production rhythms and reducing the efficiency of raw material transportation.

[0005] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows:

[0006] A metering device for fire-retardant coating raw materials includes: a silo, a guide groove communicating with the bottom end of the silo, and a pushing mechanism communicating with a working surface on one side of the guide groove; there are multiple silos, and a first weighing mechanism is provided on one side of the working surface of the silo. The first weighing mechanism extends into the silo and is adapted to the working size of the silo, and is used to weigh the fire-retardant coating raw materials in the silo; a second weighing mechanism is provided at the bottom end of the guide groove, and the second weighing mechanism is used to perform secondary weighing of the fire-retardant coating raw materials.

[0007] Furthermore, the hopper is in the shape of an inverted trapezoid, wider at the top and narrower at the bottom, with fixed supports on both sides. One end of each fixed support is fixedly connected to the guide groove. The fixed supports are interconnected by connecting rods.

[0008] Furthermore, the first weighing mechanism includes: a housing and a weighing plate movably connected to the housing; the housing is disposed on a working surface on one side of the silo and is connected to the silo, and a first motor is provided thereon, the output end of the first motor being connected to the weighing plate; the working dimensions of the housing and the weighing plate are adapted to each other.

[0013] (I) This utility model enables the initial weighing of fire-retardant coating raw materials in the silo through the setting of the first weighing mechanism, and the secondary weighing through the second weighing mechanism set at the bottom of the guide trough.

[0020] To make the content of this utility model easier to understand, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0021] like Figure 1-2 As shown, this embodiment provides a metering device for fire-retardant coating raw materials, including: a silo 1, a guide groove 3 communicating with the bottom of the silo 1, and a pushing mechanism 4 communicating with a working surface on one side of the guide groove 3; there are multiple silos 1, which can meet the actual production needs of storing and metering multiple raw materials for fire-retardant coatings at the same time; a first weighing mechanism 2 is provided on one side of its working surface, the first weighing mechanism 2 extends into the silo 1 and is adapted to the working size of the silo 1, and is used to weigh the fire-retardant coating raw materials in the silo 1; the first weighing mechanism 2... During operation, the first weighing mechanism 2 is inserted into the hopper 1 to seal it, and then the raw materials in the hopper 1 are weighed. After weighing, the first weighing mechanism 2 is retracted and the hopper 1 is opened, at which time the raw materials fall into the guide groove 3. The bottom of the guide groove 3 is equipped with a second weighing mechanism 6, which is used to weigh the fireproof coating raw materials a second time. The guide groove 3 weighs the falling raw materials a second time. Through the double weighing mechanism, the accuracy of raw material measurement is further improved, and the measurement error is greatly reduced, thereby producing high-quality and stable protective coatings.

[0022] Furthermore, the hopper 1 is inverted trapezoidal, wider at the top and narrower at the bottom. The wider top facilitates the rapid and large-scale loading of fire-retardant coating raw materials, while the narrower bottom helps the raw materials to naturally converge under gravity and flow more smoothly into the guide channel 3, effectively preventing accumulation and residue within the hopper. Fixed supports 8 are provided on both sides of the hopper 1, with one end of each support fixedly connected to the guide channel 3. These supports securely connect the hopper 1 and the guide channel 3 and can withstand corresponding pressure. The fixed supports 8 are interconnected via connecting rods 9, and both ends of the fixed supports 8 are connected to the support frame 7. The arrangement of the support frame 7, connecting rods 9, and fixed supports 8 ensures the stability of the device during operation and guarantees the smooth metering of the protective coating raw materials.

[0023] like Figure 4As shown, the first weighing mechanism 2 includes: a housing 202 and a weighing plate 203 movably connected to the housing 202; the housing 202 is disposed on one side of the working surface of the silo 1 and is connected to the silo 1, and the weighing plate 203 can freely extend and retract within the silo 1; a first motor 201 is provided on the housing 202, and the output end of the first motor 201 is connected to the weighing plate 203. When the first motor 201 is started, it can accurately control the weighing plate 203 to move accordingly within the housing 202, thereby realizing accurate measurement of the raw materials in the silo 1; the working dimensions of the housing 202 and the weighing plate 203 are adapted to each other. This ensures that the weighing plate 203 moves smoothly and unobstructed within the housing 202, and guarantees the accuracy and stability of the weighing process, avoiding errors or malfunctions caused by size mismatch. The second weighing mechanism 6 includes: a mounting base 601, which is connected to the bottom of the guide groove 3. One side of the mounting base 601 has a display screen and control buttons, and the top has a weighing sensor 602. The weighing sensor 602 is a resistance strain gauge type. When the weight of the fire-retardant coating material in the guide groove 3 acts on the elastomer, the elastomer undergoes elastic deformation. Strain gauges made of metal foil or semiconductor material are attached to the surface of the elastomer. Deformation causes a corresponding change in the resistance of the strain gauge. According to the resistance-strain effect, the change in resistance is proportional to the applied stress, which in turn is related to the weight of the material acting on the sensor. A Wheatstone bridge circuit converts the change in strain gauge resistance into a measurable voltage change. This weak voltage signal is amplified and outputs an electrical signal proportional to the weight of the raw material. This signal can be acquired and processed by subsequent circuits, ultimately converting it into a visually appealing weight value displayed on the screen. Its model number is Z6FC3-100kg, which can meet the metering requirements of raw materials in most fire-retardant coating production processes. The weighing sensor 602 is used to weigh the material within the guide groove 3. The raw materials for fire-retardant coatings are weighed. During operation, the first motor 201 drives the weighing plate 203 to seal the hopper 1. At this time, the operator adds raw materials to the hopper 1, and the weighing plate 203 performs an initial weighing of the raw materials. After the initial weighing is completed, the first motor 201 retracts the weighing plate 203. At this time, the weighing plate 203 is located inside the housing 202, and the raw materials fall onto the weighing sensor 602 at the bottom of the guide groove 3. The weighing sensor 602 performs a second weighing, compares the two results, and takes the average value to ensure that the amount of fire-retardant coating raw materials put into production is accurate, thereby ensuring the stability of the quality of fire-retardant coating products and avoiding product performance fluctuations caused by inaccurate raw material measurement.

[0024] like Figure 3-4As shown, the feeding mechanism 4 includes: a feeding pipe 401, a second motor 402, and an auger 403 connected to the output end of the second motor 402; the feeding pipe 401 has a discharge cylinder 5 at one end away from the guide groove 3, which serves to concentrate the discharge and guide the flow of raw materials, so that the raw materials can be accurately transported to the subsequent process in a predetermined direction; the second motor 402 is located on one side of the guide groove 3; one end of the auger 403 is rotatably connected to the discharge cylinder 5; the auger 403 avoids blockage or accumulation of raw materials during the conveying process, ensuring the efficiency and continuity of the entire feeding process; when the second motor 402 starts running, its output end drives the auger 403 to rotate synchronously, and the spiral blades on the auger 403 push the fireproof coating raw materials in the guide groove 3 and the feeding pipe 401 along the pipe axis during the rotation, so that they gradually move towards the discharge cylinder 5, providing a reliable supply of raw materials for the subsequent production process.
