Among them, oil-based sealing adhesives usually use toluene as a solvent, and the main components are SBS (styrene-butadiene-styrene block copolymer), terpene resin, rosin, etc.

[0003] A Chinese utility model patent with publication number CN219897943U discloses "an automatic airflow mixer, including a mounting plate, a mounting frame, and a mixing tank. The mixing tank is fixedly installed inside the mounting frame. A discharge hopper is connected to the bottom of the mixing tank, and an electromagnetic switch valve is connected to the bottom of the discharge hopper. An air inlet pipe is fixedly connected to the surface of the discharge hopper. A feed pipe is connected to the top of the mixing tank. An exhaust pipe is connected to one side of the top of the mixing tank. A support plate is fixedly installed on one side of the surface of the discharge hopper.

The sampling mechanism includes a sampling pipe, an auger, a rocker wheel, a discharge pipe, a manual valve, and a sampling cylinder. The sampling pipe is fixedly installed on the surface of the support plate." However, the sampling pipe of this device is located in the bottom area of ​​the mixing tank. Therefore, it can only sample and observe a portion of the material after mixing, and cannot reflect the overall uniformity of the mixing process, which has certain limitations. Utility Model Content

[0004] The purpose of this utility model is to solve the technical problems mentioned in the background art by proposing a gas flow mixing device for adhesive raw materials. This device not only has efficient gas flow mixing capabilities, but also achieves real-time monitoring of the mixing process through a scientifically designed sampling structure, which helps to improve product quality and production efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An airflow mixing device for adhesive raw materials includes a frame, a mixing silo fixedly mounted on the frame, an airflow mixing module mounted at the bottom of the mixing silo, and a feed pipe fixedly connected to one side of the top of the mixing silo. It also includes a sampling structure comprising three sets of sampling tubes connected to the mixing silo. The sampling tubes are arranged at three positions (top, middle, and bottom) along the axial direction of the mixing silo, and each set of sampling tubes is arranged radially along the mixing silo. A spiral auger is rotatably installed inside each sampling tube. The three spiral augers rotate synchronously under power. A discharge pipe is fixedly connected to the bottom of the free end of the sampling tube, and a sampling box is detachably connected to the bottom end of the discharge pipe.

[0007] As a further description of the above technical solution:

[0008] First synchronous pulleys are fixedly fitted on the free ends of the augers located at the upper and middle positions of the mixing hopper. The two sets of first synchronous pulleys are connected by a first synchronous belt. Second synchronous pulleys are fixedly fitted on the free ends of the augers located at the middle and lower positions of the mixing hopper. The two sets of second synchronous pulleys are connected by a second synchronous belt. A drive motor is fixedly installed on the frame and is connected to the free end of the auger located at the lower position of the mixing hopper.

[0009] As a further description of the above technical solution:

[0010] A second electromagnetic switch valve is installed on the feed pipe.

[0011] As a further description of the above technical solution:

[0012] The sampling box and the feeding tube are connected by a threaded connection.

[0013] As a further description of the above technical solution:

[0014] The airflow mixing module includes a mixer, a first electromagnetic switch valve, a discharge pipe, and an air inlet pipe. The mixer is fixedly connected to the bottom of the mixing hopper, the discharge pipe is fixedly connected to the bottom of the mixer, the first electromagnetic switch valve is installed on the discharge pipe, and the air inlet pipe is fixedly connected to one side of the mixer.

[0015] As a further description of the above technical solution:

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: the power system composed of a drive motor, synchronous belt and synchronous pulley enables all the upper, middle and lower spiral augers to rotate synchronously. Under the action of the spiral augers, the material is extracted from different height levels (upper, middle and lower) of the mixing hopper and falls into the sampling box through the corresponding discharge pipe. The material at different height levels during the mixing process can be sampled and tested without stopping the machine, overcoming the limitation of traditional airflow mixing devices that only sample from the bottom, and can more comprehensively reflect the uniformity of material mixing.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4This utility model provides a technical solution: an airflow mixing device for adhesive raw materials, which is mainly used to efficiently and uniformly mix various raw materials (such as SBS, terpene resin, rosin, etc.) for adhesive, so as to ensure that the final product has good adhesive performance. This device specifically includes a frame 1, on which a mixing hopper 2 is fixedly installed. A mixer 3 is fixedly connected to the bottom of the mixing hopper 2, and a discharge pipe 5 is fixedly connected to the bottom of the mixer 3. The mixed material enters the bottom of the mixer 3 and is discharged through the discharge pipe 5. A first electromagnetic switch valve 4 is installed on the discharge pipe 5 and is used to control the start and stop of the discharge, enabling automated discharge. An air inlet pipe 6 is fixedly connected to one side of the mixer 3. Compressed air enters the interior of the mixer 3 through the air inlet pipe 6 and is sprayed into the mixing chamber through the nozzle, causing the material to rise spirally along the hopper wall with the airflow, forming a fluidized state, thereby achieving rapid and uniform mixing. A feed pipe 7 is fixedly connected to one side of the top of the mixing hopper 2 for adding the solid or powdered raw materials to be mixed into the mixing hopper 2. A dust filter 8 is installed on the other side of the top of the mixing hopper 2. Dust generated during the mixing process is collected and filtered through the dust filter 8 to prevent dust leakage and ensure a clean working environment and safe operation.

[0026] Specifically, such as Figure 1-4 As shown, the sampling structure 9 includes three sets of sampling tubes 91 connected to the mixing silo 2. The sampling tubes 91 are arranged at the top, middle, and bottom positions along the axial direction of the mixing silo 2. Each set of sampling tubes 91 is arranged radially along the mixing silo 2, allowing sampling and testing of materials at different heights during the mixing process without stopping the machine. This overcomes the limitation of traditional airflow mixing devices that only sample from the bottom, and can more comprehensively reflect the uniformity of material mixing. Each sampling tube 91 is rotatably equipped with a screw conveyor 92, which rotates under power to transport materials from inside the sampling tube 91 to the outside. The bottom side of the free end of the sampling tube 91 is fixedly connected to a discharge pipe 96, through which the sample is discharged. A second electromagnetic switch valve 95 is installed on the discharge pipe 96, which is used to control the sampling timing. The bottom end of the feed pipe 96 is connected to a sampling box 97 via a threaded connection. The sampling box 97 is used to receive samples. The upper and middle sets of spiral augers 92 are fixedly fitted with first synchronous pulleys 931. The two sets of first synchronous pulleys 931 are connected by a first synchronous belt 941 to ensure that the upper and middle sets of spiral augers 92 rotate synchronously. The middle and lower sets of spiral augers 92 are fixedly fitted with second synchronous pulleys 932. The two sets of second synchronous pulleys 932 are connected by a second synchronous belt 942 to ensure that the middle and lower sets of spiral augers 92 rotate synchronously. A drive motor 98 is fixedly installed on the frame 1. The drive motor 98 is connected to the lower spiral auger 92 and is powered by the drive motor 98. Through the above-mentioned synchronous pulley and synchronous belt structure, it drives all spiral augers 92 to rotate synchronously.

[0027] Working principle: In use, firstly, the raw materials to be mixed (such as SBS, terpene resin, rosin, etc.) are added to the mixing hopper 2 through the feed pipe 7. Then, compressed air is introduced into the mixer 3 through the air inlet pipe 6 and injected into the mixing hopper 2 at high speed, causing the material to rise spirally along the hopper wall with the airflow, forming a fluidized mixing state. At the same time, the dust filter 8 is activated to collect and filter the dust generated during the mixing process, keeping the working environment clean.

[0028] Secondly, when it is necessary to check the quality of the mixture, the drive motor 98 is started. The drive motor 98 drives the lower auger 92 to rotate, and through the first synchronous belt 941 and the second synchronous belt 942, all the augers 92 in the upper, middle and lower groups rotate synchronously. Under the action of the augers 92, the material is extracted from different height levels (upper, middle and lower) of the mixing bin 2, passes through the corresponding discharge pipe 96, and falls into the sampling box 97 under the control of the second electromagnetic switch valve 95. The mixing uniformity of the material is evaluated based on the state of the extracted sample. If the expected effect is not achieved, the mixing operation continues.

[0029] Finally, after confirming that the materials have been fully mixed, open the first solenoid valve 4 to allow the mixed materials to be discharged through the discharge pipe 5.

[0030] Through the above steps, a complete process from raw material input to final product output is realized. At the same time, sampling structure 9 is used to obtain samples of materials at different levels without stopping the machine, ensuring the consistency and reliability of product quality.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
