Technical Field

[0001] This utility model relates to the field of adhesive feeding technology, specifically a two-component adhesive feeding device. Background Technology

[0002] Two-component adhesives are composed of two or more different components (usually component A and component B). These components are typically not tacky or curable when stored independently; they need to be mixed in a specific ratio to undergo a chemical reaction and form an adhesive with high strength, durability, and special properties. Common two-component adhesives include epoxy resin adhesives and polyurethane adhesives, which are widely used in construction, automotive, aerospace, electronics, and furniture manufacturing.

[0003] Traditional two-component adhesive dispensing systems typically include an adhesive tank and a buffer tank. The adhesive is pumped from the buffer tank into the adhesive tank via a metering pump for mixing and use. However, during adhesive use, residual adhesive often adheres to the inner wall of the adhesive tank. This residual adhesive can harden over time, making cleaning and maintenance of the adhesive tank difficult. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a two-component adhesive supply device, which solves the technical problem that during the use of adhesive, residual adhesive often adheres to the inner wall of the adhesive tank. This residual adhesive will solidify after long-term accumulation, making the cleaning and maintenance of the adhesive tank difficult.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a two-component glue supply device, comprising: a glue tank and two buffer tanks;

[0006] The buffer tank is connected to the metering pump via a delivery pipe, and the metering pump is then connected to the inlet of the glue tank via a glue injection pipe.

[0007] The glue container is equipped with a stirring assembly, which includes a servo motor fixed to the top of the glue container and a stirring rod fixedly connected to the output end of the servo motor. The bottom end of the stirring rod extends into the interior of the glue container.

[0008] A fixing block is fixedly sleeved on the outer surface of the stirring rod. A connecting pipe is fixedly connected to the outer side of the fixing block in a circumferentially equidistant manner. A ring is fixedly connected to the end of the connecting pipe away from the fixing block. A nozzle is fixedly connected to the outer side of the ring in a circumferentially equidistant manner for cleaning the inner wall of the glue tank.

[0009] Furthermore, a waste discharge valve is installed on the conveying pipe for discharging waste liquid or gas.

[0010] Furthermore, a frame is fixedly fitted on the outer surface of the stirring rod, and stirring blades are fixedly connected to both sides of the inner wall of the frame for mixing the two-component adhesive.

[0011] Furthermore, the stirring blade is M-shaped.

[0012] Furthermore, a support rod is fixedly connected to the middle of the stirring plate, and one end of the support rod is fixedly connected to the inner wall of the frame.

[0013] Furthermore, the ring is located at the top of the frame, and both the ring and the frame are located inside the glue can, with the outer diameter of the ring being smaller than the inner diameter of the glue can.

[0014] Furthermore, a liquid level sensor is fixedly connected to the top of the glue container, and a temperature sensor and a liquid level sensor are fixedly connected to the top of the buffer container.

[0015] Furthermore, the top of the buffer tank is provided with a stirring port.

[0016] Furthermore, the glue container and the two buffer containers are all provided with observation windows on the front.

[0017] By employing the above technical solution, this utility model provides a two-component adhesive supply device, which has at least the following beneficial effects:

[0018] 1. When the inner wall of the glue tank needs to be cleaned, the cleaning water is introduced through the delivery pipe, flows through the connecting pipe to the ring, and is then sprayed evenly from the nozzle to thoroughly remove residual glue. This avoids the cleaning problems caused by glue curing and ensures the cleanliness and service life of the glue tank.

[0019] 2. When the servo motor is running, the two-component adhesive supply device will drive the stirring rod to rotate continuously in both directions, which in turn drives the ring to rotate in both directions, thereby increasing the cleaning range of the nozzle and enhancing the cleaning effect.

[0020] 3. In this two-component adhesive supply device, the servo motor drives the stirring rod to continuously rotate in both directions, which in turn drives the frame and stirring blade to rotate in both directions, improving mixing efficiency and ensuring thorough mixing and uniformity of the two-component adhesive. Simultaneously, the M-shaped stirring blade increases the contact area between the blade and the adhesive, further enhancing mixing efficiency. The M-shaped design also allows the stirring blade to generate a stronger vortex effect during mixing, promoting thorough mixing and uniformity of the adhesive. Attached Figure Description

[0027] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-4 A two-component adhesive supply device includes: an adhesive tank 1 and two buffer tanks 2; the buffer tanks 2 are connected to a metering pump 4 via a delivery pipe 3, and the metering pump 4 is connected to the inlet end of the adhesive tank 1 via an adhesive injection pipe 5.

[0029] The glue container 1 is equipped with a stirring assembly 8. The stirring assembly 8 includes a servo motor 801 fixed on the top of the glue container 1 and a stirring rod 802 fixedly connected to the output end of the servo motor 801. The bottom end of the stirring rod 802 extends into the interior of the glue container 1.

[0030] A fixing sleeve 805 is fixedly fitted onto the outer surface of the stirring rod 802. Connecting pipes are equidistantly connected to the outer side of the fixing sleeve 805 in a circular pattern. A ring 806 is fixedly connected to the end of the connecting pipe away from the fixing sleeve 805. A nozzle 807 is equidistantly connected to the outer side of the ring 806 in a circular pattern for cleaning the inner wall of the glue tank 1. When cleaning the inner wall of the glue tank 1 is required, cleaning water is introduced through the delivery pipe, flows through the connecting pipe to the ring 806, and is then evenly sprayed out by the nozzle 807, thoroughly removing residual glue. This avoids the cleaning difficulties caused by glue curing, ensuring the cleanliness and service life of the glue tank 1.

[0031] A waste discharge valve 6 is installed on the delivery pipe 3 to discharge waste liquid or gas. During the glue supply process, some waste liquid or gas is generated. If it is not discharged in time, it will affect the normal operation of the metering pump 4 and may even lead to equipment failure. The waste discharge valve 6 ensures the timely discharge of waste liquid or gas, guarantees the stable operation of the equipment, and improves production efficiency and equipment reliability.

[0032] A frame 803 is fixedly fitted onto the outer surface of the stirring rod 802. Stirring blades 804 are fixedly connected to both sides of the inner wall of the frame 803 for mixing the two-component adhesive. This increases the mixing area, improves mixing efficiency, and ensures thorough mixing and uniformity of the two-component adhesive. Simultaneously, the placement of the stirring blades 804 takes into account the fluidity of the adhesive, effectively preventing adhesion and clumping, thus guaranteeing the quality of the adhesive.

[0033] The mixing blade 804 adopts an M-shaped design, which increases the contact area between the mixing blade 804 and the adhesive, thereby improving mixing efficiency. Simultaneously, the M-shaped design also allows the mixing blade 804 to generate a stronger vortex effect during mixing, promoting thorough mixing and uniformity of the adhesive. Furthermore, the M-shaped mixing blade 804 also possesses a certain self-cleaning function, reducing adhesive adhesion and residue on the mixing blade and maintaining its cleanliness.

[0034] A support rod is fixedly connected to the middle of the mixing blade 804, with one end of the support rod fixedly connected to the inner wall of the frame 803. During mixing, the mixing blade 804 is subjected to the resistance and impact of the glue. The support rod effectively resists these forces, maintaining the shape and position of the mixing blade 804, thus ensuring the uniformity and stability of the mixing. At the same time, the support rod also strengthens the structure of the frame 803, improving the durability of the entire mixing assembly.

[0035] The ring 806 is located at the top of the frame 803. Both the ring 806 and the frame 803 are located inside the glue tank 1, and the outer diameter of the ring 806 is smaller than the inner diameter of the glue tank 1. This ensures that the ring 806 can rotate freely inside the glue tank 1 without interfering with the tank wall. The relative position of the ring 806 and the frame 803 also facilitates installation and maintenance, reducing equipment maintenance costs.

[0036] A liquid level sensor 9 is fixedly connected to the top of glue container 1, which can monitor the liquid level changes of the two-component glue in glue container 1 in real time, avoiding the situation of overflow or insufficient two-component glue. A temperature sensor 10 and a liquid level sensor 12 are fixedly connected to the top of buffer container 2, which can monitor the temperature and liquid level of the single-component glue in buffer container 2 in real time, ensuring that the storage conditions of the single-component glue meet the requirements.

[0037] The top of the buffer tank 2 is equipped with a stirring port 11, which facilitates any subsequent stirring operations. In some cases, it is necessary to stir the single-component adhesive in the buffer tank 2 or add other substances. The stirring port 11 makes these operations easier and more convenient. At the same time, the stirring port 11 can also serve as an inspection port for the equipment, facilitating maintenance and cleaning of the interior of the buffer tank 2.

[0038] All two buffer tanks 2 have observation windows 7 on their front sides, allowing operators to directly observe the glue level and equipment operating status. Through these windows, operators can promptly check the glue's level, color, and transparency to assess its quality and storage condition. Simultaneously, the observation windows 7 also serve as safety windows, facilitating inspection and handling of the equipment's internal components in emergencies. This improves the equipment's operability and safety while reducing operator workload and risks.

[0039] Working principle: When in use, the single-component glue is stored in the buffer tank 2 and pumped into the glue tank 1 by the metering pump 4;

[0040] Servo motor 801 drives stirring rod 802 to rotate, which in turn drives frame 803 and stirring blade 804 fixed on stirring rod to rotate, thereby achieving uniform mixing and stirring of two-component glue inside glue tank 1.

[0041] When the inner wall of glue tank 1 needs cleaning, cleaning water is introduced through the delivery pipe, flows through the connecting pipe to the ring 806, and is then evenly sprayed out by the nozzle 807 to thoroughly remove residual glue, avoiding the cleaning problems caused by glue curing and ensuring the cleanliness and service life of glue tank 1. Meanwhile, when the servo motor 801 is running, it drives the stirring rod 802 to continuously rotate forward and backward, which in turn drives the ring 806 to rotate forward and backward, thereby increasing the cleaning range of the nozzle and enhancing the cleaning effect.

[0042] It should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
