[0002] Adhesives, including glues, sealants, and pressure-sensitive adhesives, are essential materials in modern industry, construction, and daily life. Their performance directly affects the quality, reliability, and safety of the final product. In the production and preparation of adhesives, the precise measurement and addition of various raw materials is crucial. Traditional methods rely heavily on manual weighing and volume estimation, which is labor-intensive, cumbersome, unsuitable for continuous operation, and lacks precision control. This can lead to inconsistent performance between different batches, affecting the final product quality. Utility Model Content

Material limiting components, wherein there are two material limiting components, each disposed on the upper side of the movable plug; Through the above technical solution design, the raw materials for producing adhesives are placed in corresponding distribution bins. The movable plug is driven by the limiting component, causing the raw materials to flow downwards from the gap between the movable plug and the conical groove into the transfer bin. At this time, the movable sealing plate blocks the bottom of the transfer bin, and the raw materials accumulate inside the transfer bin. The material sensor senses the accumulation volume inside the transfer bin and sends a response to the backend. The limiting component then drives the movable plug to move upwards and lock it into the conical groove to limit the movement of the raw materials.

By designing the above technical solution, the movable motor is started, which drives the transmission gear to rotate, causing the movable sealing plate to rotate around the support column, thereby realizing the opening and closing of the transfer hopper.
[0006] As a further improvement of this utility model, the material limiting component includes: A support platform is fixedly installed on the outer ring wall of the material distribution bin. A connecting rod is fixedly mounted on the upper side of the movable plug, and a connecting block is fixedly mounted on the upper end of the connecting rod, with the connecting block mounted on the upper side of the support platform.

[0007] As a further improvement of this utility model, a limiting platform is fixedly provided at the bottom of the driving block, and the limiting platform is located on the lower side of the support platform; the limiting platform contacts the support platform to limit the movement of the driving block.
[0008] As a further improvement of this utility model, several mixing rods are fixedly arranged at equal intervals on the outer ring wall of the stirring rod, and the length of the mixing rods decreases from top to bottom; the raw materials in the conical cavity at the bottom of the feeding hopper body are stirred and mixed.
[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. The system is equipped with independent material distribution bins, transfer bins, movable plugs, and material sensors, enabling pre-, independent, and precise metering of various raw materials.

The movable plug 9 is driven by the limiting component 10, so that the raw materials flow downward from the gap between the movable plug 9 and the conical groove into the transfer bin 5. At this time, the movable sealing plate 7 is sealed at the bottom of the transfer bin 5, and the raw materials accumulate in the transfer bin 5. The material sensor 6 senses the accumulation capacity inside the transfer bin 5 and reacts to the back-end. The limiting component 10 drives the movable plug 9 to move upward and lock it with the conical groove to limit the raw materials. Subsequently, the movable component 8 drives the movable sealing plate 7 to rotate, disengage from the transfer bin 5, and let the raw materials fall into the interior of the feeding bin body 1.
[0021] Example 2:
[0022] Please see Figures 1-7 Based on Embodiment 1, the active component 8 is further improved and includes: Support column 8-1, the support column 8-1 is fixedly installed on the inner top surface of the feed hopper body 1, and the stirring rod 3 passes through the support column 8-1; The connecting platform 8-2 is fixedly installed on the upper middle part of the movable sealing plate 7, and a through groove is provided in the connecting platform 8-2, which penetrates the movable sealing plate 7.

[0023] Example 3:
[0024] Please see Figures 1-7 Based on Embodiment 1, a further improvement is made, wherein the material limiting component 10 comprises: Support platform 10-1 is fixedly installed on the outer ring wall of the material distribution bin 4; Connecting rod 10-2, the connecting rod 10-2 is fixedly disposed on the upper side of movable plug 9, and a connecting block 10-3 is fixedly disposed on the upper end of the connecting rod 10-2, the connecting block 10-3 is disposed on the upper side of support platform 10-1; The driving block 10-4 is movably inserted into the support platform 10-1 and is fixedly disposed at the bottom of the connecting block 10-3; a limiting platform 10-7 is fixedly disposed at the bottom of the driving block 10-4 and is disposed on the lower side of the support platform 10-1. The limit motor 10-5 is fixedly mounted on the upper side of the feed hopper body 1 by a motor bracket.

A threaded rod 10-6 is provided on the output end of the limit motor 10-5, and the threaded rod 10-6 is threadedly screwed into the drive block 10-4. Through the above technical solution design, the limit motor 10-5 is started, which causes the threaded rod 10-6 to rotate and drive the drive block 10-4 by thread. The drive block 10-4 moves and drives the connecting rod 10-2 to move, so that the movable plug 9 moves.
[0025] The working principle of this utility model is as follows: Step 1: Initial state and material preparation: Before production begins, the two movable plugs 9 are driven by their respective limiting components 10 to tightly engage with the conical groove at the bottom of the material distribution bin 4 to form a seal; at this time, the movable sealing plate 7 is in the closed position under the drive of the movable component 8, sealing the bottom of the transfer bin 5; the two different adhesive production raw materials are temporarily stored in the left and right material distribution bins 4 respectively. Step 2: Precise feeding and temporary storage: Start the limit motor 10-5 in the limiting component 10 to drive the threaded rod 10-6 to rotate, which in turn drives the drive block 10-4 and the connected rod 10-2 and the movable plug 9 to move slowly downward. A controllable annular gap is then created between the movable plug 9 and the conical groove. Under the action of gravity, the raw material flows through this gap and evenly into the transfer bin 5 below. Since the movable sealing plate 7 is in the closed state, the raw material will gradually accumulate in the transfer bin 5. Step 3: Quantitative sensing and cutoff: The material sensor 6 installed in the transfer hopper 5 monitors the accumulation of material in the hopper in real time; when the material reaches the preset value, the material sensor 6 feeds the signal back to the control system, and the control system then instructs the limit motor 10-5 to rotate in reverse, driving the movable plug 9 to move upward and re-engage tightly with the conical groove, cutting off the flow of raw materials; this process achieves precise and independent quantification of each raw material. Step 4: Centralized feeding and mixing: After both transfer hoppers 5 have completed quantitative feeding, the control system starts the movable component 8; the movable motor 8-4 drives the movable gear 8-5, which in turn drives the transmission gear 8-3 and the connecting table 8-2 to rotate, thereby causing the movable sealing plate 7 to rotate and move away from the bottom opening of the transfer hopper 5; the precisely metered raw materials in the two transfer hoppers 5 fall simultaneously into the feeding hopper body 1 below; then, the movable sealing plate 7 resets, ready for the next quantitative operation.
[0026] Compared with the prior art, the beneficial effects of this utility model are: 1. The system is equipped with independent material distribution bins 4, transfer bins 5, movable plugs 9, and material sensors 6, which enables the pre-, independent, and precise metering of various raw materials. This ensures that the mixing ratio of each batch is highly accurate, fundamentally guaranteeing the quality stability and consistency of the final adhesive product. It eliminates the need for manual intervention, greatly reducing labor intensity, minimizing human error, and significantly improving the level of automation and overall efficiency of production. 2. The movable plug 9 adopts a conical structure and cooperates with the conical groove at the bottom of the distribution bin 4 to form a reliable sealing pair, which effectively prevents the leakage of raw materials in the non-feeding state; the limit platform 10-7 at the bottom of the drive block 10-4 is designed to ensure the accuracy of the stroke of the movable plug 9 and further improve the reliability of the equipment. 3. The mixing rods 11, whose length decreases from top to bottom, are set on the stirring rod 3. They are particularly suitable for the conical structure at the bottom of the feeding hopper body 1. They can eliminate the dead corners of mixing and make the raw materials flow more vigorously and complexly in the hopper, thereby obtaining a more uniform and efficient mixing effect, and preparing for the subsequent adhesive production process.
