Description

Technical Field

[0001] This utility model relates to the field of hot melt adhesive powder technology, specifically a combined powder additive device. Background Technology

[0002] Hot melt adhesives, as solvent-free and fast-curing bonding materials, are widely used in packaging, building materials, electronics, automobiles, textiles, and other fields. Their performance depends not only on the characteristics of the base resin but also on the precise proportion of powder additives. These powder additives typically include functional fillers, auxiliaries, and colorants, and their addition amount usually accounts for 5% to 30% of the total mass of the hot melt adhesive. The formulation requirements must be strictly followed; otherwise, it will directly lead to fluctuations in the performance of the hot melt adhesive and even affect the quality stability of the end product. In the industrial production of hot melt adhesives, the addition of powder additives is one of the key processes.

[0003] In existing technologies, manual addition is still a common method in small and medium-sized hot melt adhesive production. The process involves manually weighing the required powder for a single batch using a platform scale or electronic scale, then manually transporting it to the hot melt adhesive reactor or mixer, and finally opening the lid to pour the material out. However, manual addition not only easily increases the workload, but also easily causes leakage during the transportation process, resulting in powder splashing in the workshop. This makes it difficult to promote and use, resulting in poor overall practicality. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a combined powder small material adding device, which can effectively solve the problems in the prior art where manual adding not only easily leads to an increase in workload, but also easily causes leakage during the conveying process, resulting in powder splashing in the workshop, which is not convenient for widespread use and has poor overall practicality.

[0005] The technical solution adopted by this utility model is: a combined powder material adding device, including a support frame and a vector scale. A feeding station is fixedly installed on the support frame. A dust collector is fixedly installed at the end of the feeding station away from the support frame. A hopper is fixedly installed at the end of the feeding station near the support frame. An auger conveyor is fixedly installed at the end of the hopper near the support frame. A conveying pipe is provided at the end of the auger conveyor away from the hopper. A weighing tank is fixedly installed on the vector scale. A conveying pipe is provided at the end of the weighing tank away from the first conveying pipe. A powder hopper is fixedly installed at the end of the second conveying pipe away from the weighing tank.

[0006] Preferably, a feeding trough is provided along the inner edge of the feeding station, and a filter plate is fixedly installed at the end of the feeding station away from the dust collector. The feeding station and the discharge hopper are interconnected, the discharge hopper has a conical cross-section, and the discharge hopper has an inclination angle greater than 60°.

[0007] The above technical solution, through the design of the feeding trough, is easy to adapt to bagged or barrelled powder feeding, reducing spillage during feeding. At the same time, with the filter plate, it is easy to intercept lumps and foreign objects in the powder, preventing impurities from entering the auger conveyor and causing blockage or damage. Furthermore, the design of the discharge hopper allows the powder to slide quickly to the outlet under the action of gravity, avoiding easy accumulation on the wall.

[0008] Preferably, the hopper and the auger conveyor are interconnected, and a drive motor is fixedly installed at the end of the auger conveyor away from the conveying pipe.

[0009] Through the above technical solution, the design of the hopper facilitates communication with the auger conveyor to form a feeding channel. The drive motor drives the auger to rotate, transporting the powder from the hopper to the conveying pipe, realizing quantitative and continuous conveying and avoiding material interruption or over-convection during powder conveying.

[0010] Preferably, a fixing frame is fixedly installed at the end of the vector scale away from the weighing tank, and the conveying pipe is connected to the weighing tank.

[0011] The above technical solution, through the design of the fixed frame, facilitates rigid connection with the ground or support frame, reduces the impact of environmental vibration on the vector scale, and the conveying pipe is connected to the inlet of the weighing tank to avoid splashing of powder during conveying and prevent leakage during conveying.

[0012] Preferably, the second conveying pipe is interconnected with the powder hopper, a positioning frame is fixedly installed at the outer edge of the powder hopper, a connecting pipe is provided at the outer edge of the powder hopper, and a dust removal component is fixedly installed at the end of the connecting pipe away from the powder hopper.

[0013] The above technical solution uses a positioning frame to fix the powder hopper, preventing powder spillage caused by vibration and displacement of the hopper. When the powder falls into the hopper, it generates dust. The fan of the dust removal component generates negative pressure, and the dust is sucked into the dust removal tank through the connecting pipe, preventing the dust from spreading to the workshop.

[0014] Preferably, the dust removal assembly includes a dust removal tank, with an active motor and a fan fixedly installed on the outer edge of the dust removal tank, and an installation sleeve fixedly installed on the inner edge of the dust removal tank.

[0015] The above technical solution utilizes a fan to provide negative pressure for dust collection, a dust collection tank to hold the dust, and an installation sleeve to fix the filter element. The multi-structure synergy achieves efficient dust collection, filtration and separation, and convenient cleaning, resulting in a long-lasting and stable dust removal effect that meets environmental protection standards and is easy to maintain.

[0016] Preferably, the end of the mounting sleeve furthest from the dust collector is fixedly mounted with a filter element body, and the filter element body has an eccentric cylindrical cross-section.

[0017] The above technical solution uses an eccentric cylindrical cross-section of the filter element body, which facilitates an increase in filtration area and can handle a larger air volume. When dust-laden airflow enters the filter element body, the eccentric structure generates a rotating airflow. Under the action of centrifugal force, the dust moves to the outside of the filter element body and falls off, reducing the amount of dust adhering to the surface of the filter element body. It also makes the airflow distribution in each area of ​​the filter element body more uniform and extends the filter element body replacement cycle.

[0018] Compared with the prior art, this utility model provides a combined powder additive device, which has the following beneficial effects: 1. This combined powder feeding device, through the design of the feeding trough, is easy to adapt to bagged or barrelled powder feeding, reducing spillage during feeding. At the same time, with the filter plate, it is easy to intercept lumps and foreign objects in the powder, preventing impurities from entering the auger conveyor and causing blockage or damage. The design of the hopper allows the powder to slide quickly to the outlet under the action of gravity, avoiding easy accumulation on the wall. The positioning frame fixes the powder hopper to prevent powder spillage caused by vibration and displacement of the hopper. When the powder falls into the hopper, it will generate dust. The fan of the dust collection component generates negative pressure and sucks the dust into the dust collection tank through the connecting pipe, preventing the dust from spreading to the workshop. 2. This combined powder additive device features an eccentric cylindrical cross-section for the filter element, which facilitates increased filtration area and allows for handling larger air volumes. When dust-laden airflow enters the filter element, the eccentric structure generates a rotating airflow, causing dust to move to the outside of the filter element and fall off under centrifugal force. This reduces the amount of dust adhering to the surface of the filter element and makes the airflow distribution in each area of ​​the filter element more uniform, thus extending the filter element replacement cycle.

A filter plate 4 is fixedly installed at the end of the feeding station 2 away from the dust collector 5. The feeding station 2 and the discharge hopper 6 are interconnected. The discharge hopper 6 has a conical cross-section and an inclination angle greater than 60°. The advantage is that the design of the feeding chute 3 makes it easy to adapt to bagged or barrelled powder feeding, reducing spillage during feeding. At the same time, with the filter plate 4, it is easy to intercept lumps and foreign objects in the powder, preventing impurities from entering the auger conveyor 7 and causing blockage or damage. Furthermore, the design of the discharge hopper 6 allows the powder to slide quickly to the outlet under the action of gravity, avoiding easy accumulation on the wall.

[0024] Specifically, the hopper 6 and the auger conveyor 7 are interconnected. The end of the auger conveyor 7 away from the conveying pipe 9 is fixedly equipped with a drive motor 8. The advantage is that the design of the hopper 6 makes it easy to connect with the auger conveyor 7 to form a feeding channel. The drive motor 8 drives the auger to rotate, conveying the powder from the hopper 6 to the conveying pipe 9, realizing quantitative and continuous conveying and avoiding material interruption or over-convenience during powder conveying.

[0025] Specifically, a fixed frame 10 is fixedly installed at the end of the vector scale 11 away from the weighing tank 12, and the conveying pipe 9 is connected to the weighing tank 12. The advantage is that the design of the fixed frame 10 makes it easy to rigidly connect to the ground or support frame 1, reducing the impact of environmental vibration on the vector scale 11. In addition, the conveying pipe 9 is connected to the feed inlet of the weighing tank 12 to avoid splashing of powder during conveying and to prevent leakage during conveying.

[0026] Example 2: Figure 2-7 As shown, this is an improvement on the previous embodiment.

[0027] Specifically, the conveying pipe 13 is interconnected with the powder hopper 14. A positioning frame 15 is fixedly installed on the outer edge of the powder hopper 14, and a connecting pipe 16 is provided on the outer edge of the powder hopper 14. A dust removal component 17 is fixedly installed at the end of the connecting pipe 16 away from the powder hopper 14. The advantage is that the powder hopper 14 is fixed by the positioning frame 15, which prevents the powder from spilling due to vibration and displacement of the hopper. When the powder falls into the hopper, dust will be generated. The fan 1703 of the dust removal component 17 generates negative pressure, and the dust is sucked into the dust removal tank 1701 through the connecting pipe 16, thus preventing the dust from spreading to the workshop.

[0028] Specifically, the dust removal component 17 includes a dust collection tank 1701. An active motor 1702 and a fan 1703 are fixedly installed on the outer edge of the dust collection tank 1701, and an installation sleeve 1704 is fixedly installed on the inner edge of the dust collection tank 1701.

[0029] Specifically, a filter element body 1705 is fixedly installed at the end of the mounting sleeve 1704 away from the dust collection tank 1701. The filter element body 1705 has an eccentric cylindrical cross-section. The advantage is that the eccentric cylindrical cross-section of the filter element body 1705 facilitates the increase of the filtration area and can handle a larger air volume. When the dust-laden airflow enters the filter element body 1705, the eccentric structure generates a rotating airflow. Under the action of centrifugal force, the dust moves to the outside of the filter element body 1705 and falls off, reducing the amount of dust adhering to the surface of the filter element body 1705. It also makes the airflow distribution in each area of ​​the filter element body 1705 more uniform and extends the replacement cycle of the filter element body 1705.

[0030] Working Principle: During operation, the feed trough 3 is designed to accommodate bagged or drummed powders, reducing spillage. Combined with the filter plate 4, it effectively intercepts lumps and foreign objects in the powder, preventing impurities from entering the auger conveyor 7 and causing blockages or damage. The discharge hopper 6 allows the powder to slide quickly towards the outlet under gravity, preventing accumulation on the walls. The discharge hopper 6 also facilitates communication with the auger conveyor 7 to form a feeding channel. The drive motor 8 rotates the auger, conveying the powder from the discharge hopper 6 to the conveying pipe 9, achieving continuous quantitative conveying and preventing material interruptions or overfeeding. The fixing frame 10 allows for rigid connection to the ground or support frame 1, reducing the impact of environmental vibrations on the vector scale 11. The conveying pipe 9 connects to the inlet of the weighing tank 12, preventing powder splashing and leakage during conveying. The positioning frame 15 secures the powder hopper 14, preventing the hopper from overflowing. Due to vibration and displacement, powder spillage occurs, and dust is generated when the powder falls into the hopper. The fan 1703 of the dust removal component 17 generates negative pressure, which is drawn into the dust collection tank 1701 through the connecting pipe 16 to prevent dust from spreading to the workshop. The negative pressure provided by the fan 1703 draws in the dust, the dust collection tank 1701 contains the dust, and the mounting sleeve 1704 fixes the filter element. The multi-structure collaboration achieves efficient dust collection, filtration separation, and convenient cleaning, making the dust removal effect long-lasting and stable, meeting environmental protection standards and easy maintenance. The filter element body 1705 has an eccentric cylindrical cross-section, which facilitates the increase of the filtration area and can handle a larger air volume. When the dust-laden airflow enters the filter element body 1705, the eccentric structure generates a rotating airflow. Under the action of centrifugal force, the dust moves to the outside of the filter element body 1705 and falls off, reducing the amount of dust attached to the surface of the filter element body 1705 and making the airflow distribution in each area of ​​the filter element body 1705 more uniform, thus extending the replacement cycle of the filter element body 1705.
