Description

Technical Field

[0001] This utility model relates to the field of raw material conveying technology, and more specifically, to a raw material guiding device. Background Technology

[0002] In industrial production, raw material feeding equipment is a key piece of equipment connecting different production processes. Its performance directly affects production efficiency, product quality, and equipment maintenance costs. With the continuous development of the industrial sector, the application of high-temperature molten raw materials, such as hot melt adhesives and high-temperature resins, is becoming increasingly widespread, which places higher demands on feeding equipment for these raw materials.

[0003] Existing technologies for feeding high-temperature molten raw materials have many shortcomings: On the one hand, the cavities of traditional material conveying equipment are mostly made of ordinary metal materials and lack effective heat insulation structures. When conveying high-temperature molten raw materials, the heat of the raw materials is easily lost through the cavity walls, causing the raw material temperature to drop and resulting in cooling and solidification. This not only blocks the conveying channel and affects the continuity of conveying, but also causes waste of raw materials. At the same time; On the other hand, existing raw material conveying equipment has obvious deficiencies in terms of cleaning and maintenance. Because raw materials tend to adhere to the inside of the equipment during the conveying process, such as the screw conveyor blades and cavity walls, especially after the high-temperature molten raw materials cool down, they will adhere tightly and are difficult to clean. Most existing equipment lacks dedicated cleaning and drying devices, and usually requires manual disassembly of the equipment for cleaning. This is not only labor-intensive and inefficient, but also leads to long downtime and affects production efficiency. Moreover, manual cleaning cannot guarantee thorough cleaning, and residual raw materials will contaminate other raw materials conveyed later, affecting product quality. Although some equipment is equipped with simple cleaning devices, they can only rinse and cannot dry the inside of the equipment. Residual moisture can cause the equipment to rust or react with the raw materials conveyed later, further affecting the service life of the equipment and the quality of the raw materials. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a raw material feeding device that has the advantages of preventing high-temperature molten raw materials from cooling and solidifying, and automatically cleaning and drying the inside of the feeding box. This solves the problems in the prior art where existing equipment is prone to raw material cooling and solidification during high-temperature molten material transportation, resulting in high maintenance costs, difficulty in cleaning the equipment, and negative impacts on production efficiency and product quality.

[0005] (II) Technical Solution To achieve the aforementioned advantages of preventing the high-temperature molten raw materials from cooling and solidifying, and automatically cleaning and drying the inside of the feed box, the specific technical solution adopted by this utility model is as follows: A raw material feeding device includes a feed box, a water pump, and a dryer. The feed box has a heating chamber inside, and an inlet pipe and an outlet pipe are respectively provided at both ends of the heating chamber. A drive motor is fixedly installed at one end of the feed box, and the output end of the drive motor extends into the inside of the feed box and is equipped with a spiral conveying blade through a coupling. The surface of the spiral conveying blade is provided with a through hole. A high-speed rotary joint is installed at one end of the spiral conveying blade through the surface of the feed box. The output ends of the water pump and the dryer are respectively equipped with a first pipe and a second pipe, and valves are installed on both the first pipe and the second pipe. The first pipe and the second pipe are connected to the high-speed rotary joint through a three-way pipe. The top and bottom surfaces of the feed box are respectively provided with a feed inlet and a feed outlet.

[0006] A control switch is fixedly installed on the outer wall of the feed box, and the control switch is electrically connected to the drive motor, water pump and dryer through wires.

[0007] The through holes are provided in multiple locations, and the multiple through holes are equidistantly distributed on the surface of the spiral conveyor blade.

[0008] The discharge port is located at one end of the bottom surface of the guide box.

[0009] The feed inlet is located at one end of the top surface of the feed box.

[0010] (III) Beneficial Effects Compared with the prior art, the present invention provides a raw material feeding device, which has the following beneficial effects: (1) The present invention provides a heating chamber in the material guide box and introduces temperature-controlled circulating heat transfer oil into the heating chamber, which can provide a stable temperature environment for the material guide box, effectively prevent high-temperature molten raw materials, such as hot melt adhesives, from cooling and solidifying due to heat loss during the conveying process, avoid blockage of the conveying channel, ensure the continuity of raw material conveying, and reduce raw material waste.

[0011] (2) This utility model achieves automatic cleaning and drying of the inside of the feed box by setting up a high-speed rotary joint, a water pump and a dryer, in conjunction with the first pipe, the second pipe and valves. When the equipment needs to be cleaned, the water pump is started by controlling the switch and the valve on the first pipe is opened. The cleaning liquid enters the inside of the feed box through the first pipe and the high-speed rotary joint under the action of the water pump, and washes the inner wall of the feed box and the spiral conveying blades. After cleaning, the valve on the first pipe is closed, the dryer is started and the valve on the second pipe is opened. The hot air generated by the dryer enters the inside of the feed box through the second pipe and the high-speed rotary joint to dry the inside of the equipment. The entire cleaning and drying process does not require manual disassembly of the equipment. The degree of automation is high, which not only reduces the intensity of manual labor, but also greatly shortens the equipment cleaning time and reduces the impact of equipment downtime. At the same time, the cleaning is thorough and the drying effect is good, which effectively avoids the contamination of the subsequent conveyed raw materials by the residual raw materials and the equipment rusting problem caused by the residual moisture, thus ensuring product quality and equipment service life.

[0015] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0016] According to an embodiment of the present invention, a raw material feeding device is provided.

[0017] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-3 As shown, a raw material feeding device according to an embodiment of the present utility model includes a feeding box 1, a water pump 14, and a dryer 15.

[0018] The core components of the raw material guiding equipment involved in this embodiment are clearly defined. The material guiding box 1 is the main cavity for conveying raw materials, the water pump 14 is used to provide cleaning fluid power during subsequent equipment cleaning, and the dryer 15 is used for drying operations inside the equipment after cleaning. Together, the three constitute the basic framework for the equipment to realize the functions of guiding, cleaning and drying.

[0019] The feed box 1 is equipped with a heating chamber 6 inside, and the heating chamber 6 is equipped with an inlet pipe 7 and an outlet pipe 8 at both ends.

[0020] The key structural design of the feed box 1 is described. The heating chamber 6 is surrounded or embedded inside the feed box 1. Its function is to keep the feed box 1 warm through the circulation of the medium. The liquid inlet pipe 7 is the input channel for the circulating heating medium, such as heat transfer oil, and the liquid outlet pipe 8 is the output channel for the circulating heating medium, forming a complete medium circulation path to ensure that the heating chamber 6 can continuously provide a stable temperature environment for the feed box 1.

[0021] A drive motor 3 is fixedly installed at one end of the guide box 1, and the output end of the drive motor 3 extends into the interior of the guide box 1 and is equipped with a spiral conveying blade 4 via a coupling.

[0022] The core structure of the equipment for power transmission and raw material conveying is described. The drive motor 3 is fixed at one end of the guide box 1 as a power source. Its output end passes through the wall of the guide box 1 and enters the interior. It is connected to the screw conveyor blade 4 through a coupling. After the motor is started, it can drive the screw conveyor blade 4 to rotate, thereby pushing the raw material to move in the guide box 1.

[0023] Furthermore, the surface of the spiral conveyor blade 4 is provided with through holes 10.

[0024] The structural details of the spiral conveyor blade 4 are supplemented. The opening of the through hole 10 has multiple functions. On the one hand, it can reduce the contact area between the blade and the raw material during the material conveying process, thereby reducing the probability of raw material adhesion. On the other hand, during cleaning, it is convenient for the cleaning fluid to pass through the through hole 10 to rinse the sides of the blade and the dead corners inside the guide box 1, thereby improving the cleaning effect.

[0025] One end of the spiral conveyor blade 4 penetrates the surface of the feed box 1 and is equipped with a high-speed rotary joint 9.

[0026] The key connecting component for conveying cleaning fluid and hot air is introduced. The end of the spiral conveyor blade 4 away from the drive motor 3 passes through the wall of the guide box 1. A high-speed rotary joint 9 is installed here. This joint can maintain a sealed connection with the external pipeline during the rotation of the spiral conveyor blade 4, so as to avoid leakage of cleaning fluid or hot air and provide a sealed and rotatable channel for the subsequent introduction of cleaning and drying media.

[0027] The output ends of the water pump 14 and the dryer 15 are respectively equipped with a first pipe 11 and a second pipe 12, and valves 13 are installed on both the first pipe 11 and the second pipe 12.

[0028] The medium delivery path and control structure of the cleaning and drying system are described. The output end of the water pump 14 is connected to the subsequent channel through the first pipe 11 for delivering cleaning liquid; the output end of the dryer 15 is connected to the subsequent channel through the second pipe 12 for delivering hot air; the valves 13 on the first pipe 11 and the second pipe 12 can control the opening and closing of the two pipes respectively, so as to realize the independent switching of cleaning and drying operations and avoid medium mixing.

[0029] The first pipe 11 and the second pipe 12 are connected to the high-speed rotary joint 9 via a tee pipe.

[0030] The connection method between the pipeline and the high-speed rotary joint 9 is clearly defined. The first pipeline 11 and the second pipeline 12 are combined into a single passage by using a three-way pipe, and then connected to the high-speed rotary joint 9. This allows the cleaning fluid or hot air to enter the interior of the spiral conveying blade 4 or the cavity of the guide box 1 through the high-speed rotary joint 9, thus completing the directional conveying of the medium.

[0031] Please refer to Figure 1 , Figure 2 The top and bottom surfaces of the feed box 1 are respectively provided with a feed inlet 2 and a discharge outlet 5.

[0032] The input and output structure of the raw materials is described. The feed port 2 is located on the top surface of the guide box 1 and serves as the inlet for the raw material input equipment, facilitating the replenishment of raw materials by the upper silo or feeding device. The discharge port 5 is located on the bottom surface of the guide box 1 and serves as the discharge port after the raw material is conveyed, making it easy to guide the raw material to the subsequent process equipment below, which meets the requirements of gravity conveying of raw materials and process connection.

[0033] Please refer to Figure 2 A control switch 16 is fixedly installed on the outer wall of the feed box 1, and the control switch 16 is electrically connected to the drive motor 3, the water pump 14 and the dryer 15 through wires.

[0034] The control structure of the equipment is explained. The control switch 16 is fixed on the outer wall of the feed box 1, which is convenient for operators to operate nearby. It is connected to the drive motor 3, water pump 14 and dryer 15 through wires, which can realize the start and stop control of these three core power components, thereby regulating different operation processes such as raw material conveying, cleaning and drying, and improving the ease of operation of the equipment.

[0035] Please refer to Figure 1 and Figure 3 Multiple through holes 10 are provided, and the multiple through holes 10 are equidistantly distributed on the surface of the spiral conveyor blade 4.

[0036] The setting parameters of the through holes 10 are further refined. "Multiple" ensures that the through holes 10 can act evenly on the surface of the spiral conveyor blade 4, while "equally distributed" ensures that the material adhesion reduction effect in each area of ​​the blade is consistent with the cleaning fluid flow effect, avoiding incomplete cleaning in some areas or differences in material conveying resistance due to uneven distribution of the through holes 10.

[0037] Please refer to Figure 1 , Figure 2 The discharge port 5 is located at one end of the bottom surface of the guide box 1.

[0038] The specific location of the discharge port 5 is clearly defined. The "bottom end" usually corresponds to the end of the spiral conveyor blade 4, which is the endpoint where the raw material moves under the push of the blade. This ensures that after the raw material is conveyed to the end of the guide box 1, it can be discharged directly from the discharge port 5 below, reducing the residue of raw material in the guide box 1 and improving the conveying efficiency.

[0039] Please refer to Figure 1 , Figure 2 The feed inlet 2 is located at one end of the top surface of the feed box 1.

[0040] The specific location of the feed inlet 2 is clearly defined. The "top end" usually corresponds to the starting end of the spiral conveyor blade 4. After the raw material is put in from this end, it can be immediately received by the rotating spiral conveyor blade 4 and pushed forward, avoiding the accumulation of raw material below the feed inlet 2 and ensuring the continuity of raw material conveying.

[0041] Working Principle: When conveying high-temperature molten raw materials, such as hot melt adhesive, the relevant temperature control system is first activated by control switch 16, allowing circulating heat transfer oil to enter the heating chamber 6 inside the material guide box 1 through the inlet pipe 7. During the flow of the heat transfer oil within the heating chamber 6, heat exchange occurs between the heat transfer oil and the material guide box 1, heating the inner wall and internal space of the chamber. Once the temperature stabilizes within the suitable range of 50-300℃, the high-temperature molten raw material is fed in through the feed port 2 on the top surface of the material guide box 1. Subsequently, the drive motor 3 is activated by control switch 16. The output torque of the drive motor 3 is transmitted to the spiral conveyor blades 4 via the coupling, causing the spiral conveyor blades 4 to rotate inside the material guide box 1. The rotating blades push the raw material along the length of the material guide box 1 towards the discharge port 5. During this process, the circulating heat transfer oil in the heating chamber 6 continuously keeps the material guide box 1 warm, preventing the raw material from cooling and solidifying due to heat loss. The equidistant through holes 10 on the surface of the spiral conveyor blades 4... To reduce material adhesion and facilitate smooth material flow, the material is finally discharged from the outlet 5 at one end of the bottom of the guide box 1, completing the material guiding process. When cleaning the inside of the equipment is required, the drive motor 3 is turned off by the control switch 16, the valve 13 on the first pipe 11 is opened, and the water pump 14 is started. The water pump 14 pressurizes the cleaning solution and introduces it into the guide box 1 through the first pipe 11, the three-way pipe, and the high-speed rotary joint 9. At the same time, the drive motor 3 can be briefly started to drive the spiral conveyor blades 4 to rotate slowly, so that the cleaning solution can fully contact the inner wall of the guide box 1 and the surface of the blades. The blades are thoroughly rinsed through the through hole 10. After cleaning, the water pump 14 and the valve 13 on the first pipe 11 are turned off, the valve 13 on the second pipe 12 is opened, and the dryer 15 is started. The hot air generated by the dryer 15 enters the guide box 1 through the second pipe 12, the three-way pipe, and the high-speed rotary joint 9, cooperating with the spiral conveyor blades 4. The machine rotates slowly, and hot air flows evenly through the inside of the equipment to dry the residual moisture. After drying, the dryer 15 and valve 13 of the second pipeline 12 are closed, and the equipment is ready for the next feeding operation.
