Description

Technical Field

[0001] This utility model relates to the technical field of adhesive coating mechanisms, specifically an adjustable metering mechanism for the amount of melamine adhesive applied. Background Technology

[0002] In the industrial production of melamine glue coating, precise control of the coating amount is the core requirement for reducing glue loss and controlling production costs. The opening and closing size of the discharge port of the adjustable metering mechanism directly determines the amount of glue discharged per unit time, which is a key link to avoid excessive glue consumption and waste.

[0003] Existing adjustable melamine glue application metering mechanisms often employ bolt-tightening gap adjustment without a dedicated shielding and limiting structure. They rely on manual experience to judge the outlet opening, making it difficult to accurately match actual glue usage requirements. This can easily lead to glue overflow or excessive glue application due to over-adjustment, resulting in significant waste. Furthermore, traditional adjustment structures lack stable shielding and sealing performance, and gap shifts caused by equipment vibration after adjustment can lead to fluctuations in glue output. This not only increases glue consumption costs but may also affect subsequent processing quality. Therefore, we propose an adjustable melamine glue application metering mechanism.

[0016] 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.

[0017] like Figures 1-4 As shown, an adjustable metering mechanism for melamine glue application includes a glue storage tank 1. A feed inlet 2 is fixedly connected to the left side of the glue storage tank 1, and the feed inlet 2 is connected to a conveying pipe via a flange. A discharge outlet 3 is fixedly connected to the bottom of the glue storage tank 1. Both the feed inlet 2 and the discharge outlet 3 are connected to the interior of the glue storage tank 1. The bottom of the glue storage tank 1 is equipped with an adjustment component 4. The opening and closing size of the discharge port 3 of the glue storage tank 1 is adjusted by the adjustment component 4. The top of the glue storage tank 1 is equipped with a cylinder 5. The bottom of the cylinder 5 is fixedly connected to a piston rod 6. The piston rod 6 slides linearly inside the glue storage tank 1.

[0018] The adhesive enters the storage tank 1 through the inlet 2. The outlet 3 is adjusted to the target opening degree and locked by the adjustment component 4. The cylinder 5 pushes the piston rod 6 to assist in adhesive supply. The adhesive is accurately coated onto the workpiece through the outlet 3. During the operation, the transparent storage tank 1 and the scale value 7 are monitored in real time. Adhesive is replenished or the opening degree is finely adjusted as needed to achieve an efficient cycle of adhesive supply, adjustment, coating and monitoring, ensuring the quality and efficiency of adhesive coating.

[0019] As a technical optimization of this utility model, the adjusting component 4 includes a bearing 41 built into the bottom of the glue storage tank 1 on the left side of the discharge port 3. A connecting rod 42 is fixedly connected to the bearing 41. A spring 43 is fixedly connected inside the connecting rod 42. A slider 44 is fixedly connected to the other end of the spring 43. The slider 44 slides linearly inside the connecting rod 42. A baffle 45 is fixedly connected to the bottom of the slider 44. A sealing ring is fixedly connected to the side of the baffle 45 facing the discharge port 3. A ratchet 46 is fixedly connected to the outer wall of the connecting rod 42. A movable chamber 47 is fixedly connected to the bottom of the glue storage tank 1 on the left side of the ratchet 46. A rotating rod 48 is rotatably connected inside the movable chamber 47. A torsion spring 49 is wound around the surface of the rotating rod 48 inside the movable chamber 47. A pawl 410 is fixedly connected to the outer end of the rotating rod 48. The pawl 410 meshes with the ratchet 46.

[0020] In use, grasp the semi-circular groove of the pawl 410 and rotate the rotating rod 48. The torsion spring 49 winds and stores force, and the pawl 410 engages with the ratchet 46, driving the connecting rod 42 to rotate around the bearing 41. The slider 44 moves the baffle 45 closer to or away from the discharge port 3. Release the slider 44, and the restoring force of the spring 43 pulls the slider 44 back to its original position within the connecting rod 42, making the baffle 45 fit tightly against the discharge port 3. The sealing ring performs its sealing function to prevent glue leakage. By adjusting the covering area of ​​the baffle 45, the opening and closing size of the discharge port 3 can be adjusted, thereby controlling the glue output. After adjusting to the target opening, release the pawl 410, and the torsion spring 49 releases its elasticity, pushing... Rotating rod 48 and pawl 410 are reset. Pawl 410 locks the tooth groove of ratchet 46, locking the opening of outlet 3 to prevent deviation. Triamine glue enters storage tank 1 through one-way valve 8 of inlet 2. One-way valve 8 prevents glue backflow. Cylinder 5 is activated. Cylinder 5 drives piston rod 6 to slide linearly in storage tank 1, squeezing the glue downwards. This helps the glue flow out stably from outlet 3, improving glue uniformity. The transparent storage tank 1 allows staff to easily observe the remaining glue in the tank. The scale value 7 on the outer wall can help judge the glue consumption rate and replenish glue in time through inlet 2. At the same time, the flow state of the glue can be observed. If any abnormality occurs, the opening of outlet 3 can be adjusted in time or the fault can be troubleshooted.

[0021] As a technical optimization of this utility model, the outer wall of the pawl 410 is provided with a groove, and the groove is designed in a semi-circular arc shape.

[0022] In practice, the semi-circular groove conforms to ergonomic design, making it easy for operators to grip and apply force with their fingers or tools. Even if there is melamine glue residue on the hands, it can effectively prevent slipping. At the same time, the arc structure of the groove can prevent scratches on the hands when applying force, improving the convenience and safety of adjustment operations.

[0023] As a technical optimization of this utility model, the torsion spring 49 is wound around the surface of the middle section of the rotating rod 48, and one end of the torsion spring 49 is welded to the inner wall of the movable chamber 47.

[0024] In practice, the mid-section winding ensures that the torsion spring 49 is subjected to uniform force, avoids elasticity attenuation or breakage due to force deviation, and extends the service life of the torsion spring 49. Compared with bolts or adhesives, the welding connection method has higher connection strength and corrosion resistance, can be used for a long time in the melamine glue environment, prevents the torsion spring 49 from falling off, ensures that the torsion spring 49 can store force synchronously when the rotating rod 48 rotates, and can quickly reset and lock the ratchet 46 after the pawl 410 is released.

[0025] As a technical optimization of this utility model, the slider 44 is designed in a rectangular shape, and the connecting rod 42 has a rectangular groove that matches the slider 44.

[0026] In practice, it is ensured that the slider 44 can only slide linearly along the axis of the connecting rod 42 to avoid the slider 44 from shifting and causing uneven contact between the baffle 45 and the discharge port 3. At the same time, the adapted rectangular structure can reduce the gap between the slider 44 and the rectangular groove, reduce the risk of adhesive residue entering the gap and causing jamming, and ensure long-term stability of the adjustment action.

[0027] As a technical optimization of this utility model, the glue storage tank 1 is designed to be transparent, and two sets of scale values ​​7 are symmetrically fixedly connected to the outer wall of the glue storage tank 1.

[0028] In practice, the transparent design allows operators to observe the remaining amount, color, and flow status of the melamine glue in the tank in real time, promptly detect problems such as insufficient glue or deterioration, and avoid empty tank operation or use of unqualified glue. The symmetrical design allows operators to read glue volume data from both sides of the glue storage tank 1, adapting to the needs of different operating positions. The accuracy of the scale value 7 can reach the millimeter level, which can help judge the glue consumption rate. Together with the adjustment component 4, it can precisely control the amount of glue applied, further reducing glue loss.

[0029] As a technical optimization of this utility model, a one-way valve 8 is provided on the feed inlet 2, and the input end of the one-way valve 8 is designed in a pentagonal shape.

[0030] In practice, the one-way valve 8 prevents the melamine glue in the storage tank 1 from flowing back into the delivery pipe, avoiding contamination of the glue in the delivery pipe or blockage of the delivery pipe. At the same time, it prevents air from entering the storage tank 1 through the inlet 2 and forming air bubbles, which would affect the uniformity of glue application. The pentagonal design requires the use of a special pentagonal tool to operate, which can prevent unauthorized personnel from misoperating and causing damage or leakage to the one-way valve 8. In addition, the sealing performance of the pentagonal interface is better than that of the ordinary round interface, further improving the leak-proof performance of the inlet 2.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
