Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, specifically to a valve core adhesive coating device. Background Technology

[0002] In industrial manufacturing, valve core installation and lubrication are crucial for ensuring normal equipment operation. Traditional valve core lubrication primarily relies on manual application of grease, a method with significant limitations. Specifically, the lack of precise measurement control makes it difficult to maintain a consistent application amount. This can lead to some valve cores receiving too much grease, resulting in waste and environmental pollution; while others may receive too little, affecting lubrication and shortening equipment lifespan. Furthermore, the limitations of manual operation often result in uneven grease application across the valve core surface. Insufficient lubrication in certain areas can lead to accelerated wear and jamming during operation; while excessive lubrication in others can cause grease buildup and impurity adsorption, similarly impacting valve core performance and stability.

[0003] Chinese patent application CN113522647A discloses a spiral adhesive applicator valve. High-pressure airflow is introduced into the valve, creating a spiral airflow at the nozzle outlet. This airflow drives the adhesive strip, which is extruded through a blower spindle, to form a spiral structure, facilitating control of the adhesive output and ensuring proper filling. While this solution also involves an adhesive application process, it addresses the difficulty in controlling the amount of adhesive applied during edge folding and does not provide insights into solving the aforementioned technical problem. Utility Model Content

[0004] To overcome the problems of inconsistent application amount and uneven application caused by traditional manual application of grease in the prior art, this utility model provides a valve core gluing device. The device uses a glue applicator to control the amount of grease dispensed, controls the valve core to rotate evenly through a handwheel, and completes the uniform application of grease with a glue brush.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A valve core adhesive applicator includes a base plate, a rotating device, and an adhesive dispensing device. The rotating device and the adhesive dispensing device are both fixed on the upper surface of the base plate. The rotating device includes a rotating shaft seat and a rotating assembly, with the rotating assembly disposed on the rotating shaft seat. The adhesive dispensing device includes a support plate and a needle tube, with the needle tube disposed on the support plate. The rotation axis of the rotating assembly is orthogonal to the axial direction of the needle tube.

[0007] Furthermore, the rotating assembly includes a bearing, a retaining ring, and a rotating shaft. Adjustable sliding retaining seats are symmetrically arranged on both sides of the rotating shaft seat. The adjustable sliding retaining seats are connected to the base plate. The rotating shaft seat is an arched plate with a mounting hole at the center of the arch. Two positioning retaining rings are embedded inside the mounting hole. The bearing is built into the annular cavity formed by the retaining rings. The rotating shaft passes through the inner ring of the bearing and is coaxially assembled with the bearing.

[0008] Furthermore, the rotating device also includes a handwheel, a rotating base, connecting bolts, and a valve core. The handwheel is fixedly connected to one end of the rotating shaft by bolts, and the other end of the rotating shaft is coaxially assembled with the rotating base by connecting bolts. The rotating base is engaged with the valve core.

[0009] Furthermore, the support plate includes an upright plate and a support plate. The upright plate is an inverted "T"-shaped plate with fixed brackets symmetrically arranged on both sides of the bottom of the upright plate. The support plate is a square plate, which is horizontally arranged and fixedly connected to the top of the upright plate. The support plate is provided with a hole for the needle tube to pass through, and the needle tube is vertically installed on the support plate through the hole.

[0010] Furthermore, the adhesive applicator also includes an adhesive brush, which is horizontally mounted on the vertical plate at the same height as the valve core, and the bristles of the adhesive brush are in contact with the outer surface of the valve core.

[0011] Furthermore, the tip of the needle is connected to a glue applicator that controls the glue dispensing time and amount.

[0012] Furthermore, the valve core is located directly below the needle tube.

[0013] The beneficial effects of this utility model are as follows:

[0014] (1) Reduce manual operation. This utility model is equipped with a rotating device and a glue applicator, which reduces the step of manually applying lubricating grease, lowers labor costs, and avoids the impact of human factors on glue application efficiency.

[0015] (2) Stable glue dispensing. This utility model is equipped with a glue applicator, which can maintain a constant glue dispensing rate per second and automatically stop after a set time, thereby ensuring that the amount of grease applied each time is consistent.

[0016] (3) Improve the quality of grease application. This invention controls the valve core to rotate at a uniform speed through a handwheel drive mechanism, and works with a grease application brush to evenly apply the grease to the valve core, effectively solving the problem of uneven application in the traditional manual application method.

[0017] In summary, this utility model, through its glue applicator and structural design, maintains a constant glue output and solves the problem of uneven application caused by traditional manual application methods. This not only significantly improves the quality and efficiency of glue application but also enhances the automation of the glue application process. Attached Figure Description

[0026] A valve core adhesive applicator includes a base plate 6, a rotating device, and an adhesive applicator. The rotating device and the adhesive applicator are both fixed on the upper surface of the base plate 6. The rotating device includes a rotating shaft seat 5 and a rotating assembly. The rotating assembly is disposed on the rotating shaft seat 5. The adhesive applicator includes a support plate and a needle tube 7. The needle tube 7 is disposed on the support plate. The rotation axis of the rotating assembly is orthogonal to the axial direction of the needle tube 7.

[0027] The rotating assembly includes a bearing 3, a retaining ring 4, and a rotating shaft 2. Adjustable sliding retaining seats are symmetrically arranged on both sides of the rotating shaft seat 5. The adjustable sliding retaining seats are connected to the base plate 6. The rotating shaft seat 5 is an arched plate with a mounting hole at the center of the arch. Two positioning retaining rings 4 are embedded in the inner side of the mounting hole. The bearing 3 is built into the annular cavity formed by the retaining rings 4. The rotating shaft 2 passes through the inner ring of the bearing 3 and is coaxially assembled with the bearing 3.

[0028] The rotating device also includes a handwheel 1, a rotating seat 10, a connecting bolt 11, and a valve core 12. The handwheel 1 is fixedly connected to one end of the rotating shaft 2 by bolts, and the other end of the rotating shaft 2 is coaxially assembled with the rotating seat 10 by the connecting bolt 11. The rotating seat 10 is engaged with the valve core 12.

[0029] The support plate includes a vertical plate 9 and a support plate 8. The vertical plate 9 is an inverted "T"-shaped plate, and fixed brackets are symmetrically arranged on both sides of the bottom of the vertical plate 9. The support plate 8 is a square plate, which is horizontally arranged and fixedly connected to the top of the vertical plate 9. The support plate 8 is provided with a hole for the needle tube 7 to pass through, and the needle tube 7 is vertically installed on the support plate 8 through the hole.

[0030] The glue applicator also includes a glue-applying brush 13, which is horizontally mounted on the vertical plate 9.

[0033]

Example 2

[0034] This embodiment further illustrates the workflow of this utility model in conjunction with the above structure:

[0035] First, confirm that the glue applicator, rotating device and rotating seat 10 are installed in place, and conduct no-load debugging of the equipment to ensure that each component operates normally. The rotating seat 10 is used to fix the valve core 12. Select a suitable rotating seat 10 according to the specifications of the valve core 12, and install the valve core 12 on the rotating seat 10 to complete the adaptation of the valve core 12 bearing mechanism.

[0036] Inject an appropriate amount of grease into the syringe, ensuring that the syringe 7 is well sealed and there is no risk of leakage. Fix the valve core 12 to be coated onto the rotating base 10, and adjust the adjustable sliding shaft of the rotating shaft base 5 so that the valve core 12 is directly below the syringe 7.
