Description

Technical Field

[0001] This application relates to the field of caster processing technology, and in particular to a glue-applying device for mass production of casters. Background Technology

[0002] Casters, as key components installed on the bottom of various equipment, furniture, and vehicles for convenient movement, consist of wheels, a bracket, a steering mechanism, and a braking device. Wheels are made of materials such as rubber, plastic, polyurethane, or metal, utilizing the different material properties to achieve rolling; for example, rubber wheels offer excellent shock absorption, while polyurethane wheels have superior wear resistance. The bracket, typically made of metal or high-strength plastic, supports the wheels and connects to the moved object, providing both fixation and force transmission. Some casters are equipped with a steering mechanism; for example, swivel casters use a steering shaft and bearings to flexibly turn, facilitating movement in different directions. Braking devices include foot brakes and hand brakes, which can brake the wheels or bracket when needed to maintain a fixed position. Casters come in various categories. By application, they can be divided into industrial casters, furniture casters, and medical casters. Industrial casters have a high load-bearing capacity, furniture casters emphasize aesthetics and quiet operation, and medical casters require high flexibility, stability, and hygiene. By the number of wheels, they can be single-wheeled or double-wheeled. Single-wheeled casters have a simple structure and are suitable for light loads, while double-wheeled casters provide greater load-bearing capacity and stability. By steering method, they can be divided into directional casters and swivel casters. Directional casters roll in a fixed direction and are often used where straight-line movement is required, while swivel casters can rotate 360 ​​degrees, facilitating flexible steering in confined spaces.

[0003] Traditional caster gluing processes have many drawbacks. Early methods involved manual gluing, with workers using hand-held glue guns to apply glue to the casters. This was not only labor-intensive and extremely inefficient—a skilled worker could only glu a few hundred casters a day at most, insufficient for large-scale orders—but also highly susceptible to subjective factors, making it difficult to guarantee consistent glue thickness and uniformity. With industry development, semi-automatic gluing equipment began to be used. While these devices improved efficiency to some extent, their gluing methods were limited, typically only suitable for casters of specific sizes and shapes. When dealing with casters of different sizes and structures, such as those with diameters ranging from 50mm to 200mm and single-wheel and double-wheel configurations, the equipment required frequent tooling changes, each taking approximately 30-60 minutes, severely impacting production schedules. Furthermore, semi-automatic gluing equipment required frequent manual touch-ups, and the casters' positioning on the equipment was poor, easily shifting during gluing, thus failing to meet the demands of automated, streamlined gluing operations. Summary of the Invention

[0004] This device provides a glue application apparatus for mass production of casters, and the specific implementation method is as follows:

[0005] A glue-applying device for mass production of casters, comprising:

[0006] A rotary table, the rotating part of the rotary table is provided with several conical seats along its circumference for mounting casters;

[0007] The through-type drying chamber is a drying box located on the rotation trajectory of the rotary table. The front and rear ends of the drying box are equipped with a glue application component and a glue scraping component that acts on the surface residue. Both the glue application component and the glue scraping component are equipped with a positioning drive component that acts vertically on the top of the casters.

[0008] A glue application assembly is arranged in parallel with the glue application assembly. The glue application assembly includes a drive box, and the output end of the drive box is equipped with a glue application roller that acts on the side of the caster via a flip plate.

[0009] Based on the above technical solution, the positioning drive component and the conical seat cooperate to vertically limit the caster, ensuring that the caster remains stable throughout the glue application process and preventing factors such as shaking or displacement from affecting the glue application quality. The automatic glue application operation is controlled by the drive box, which serves as the power control center of the entire glue application system. After the caster is stably positioned under the combined action of the positioning drive component and the conical seat, the drive box drives the glue application roller to rotate to a vertical position and gradually approach the caster, which is rotating. With the close contact between the glue application roller and the caster surface, the glue evenly adhered on the roller is applied to the caster surface, achieving high-quality and high-efficiency automatic glue application, effectively improving the consistency and production efficiency of caster products.

[0010] The glue application assembly includes a glue application roller and a glue dispensing box located above the glue application roller. A glue-gathering frame is provided between the nozzle of the glue dispensing box and the glue application roller. After the glue application roller is flipped to a horizontal position, it comes into contact with the glue application roller to perform automated glue application.

[0011] Preferably, the positioning drive assembly includes a column, on which a lifting drive component is provided, and at the output end of the lifting drive component is a lifting plate; the lifting plate extends above the rotating part of the rotary table, and a rotating rod driven by a first motor is installed on the lifting plate, with a conical head inserted into the top of the caster at the bottom of the rotating rod.

[0012] Preferably, the glue application assembly also includes a vertical plate for mounting a second motor, the output end of which is connected to the glue application roller; mounting tubes are arranged side by side on the side of the vertical plate, and the glue dispensing box is mounted on the mounting tubes by bolts.

[0013] Based on the above technical solution, the width of the glue-gathering frame matches the width of the glue-applying roller. The glue-gathering frame can gather and collect the glue that drips from the glue box onto the surface of the glue-applying roller, and the edge of the glue-gathering frame achieves uniform distribution of the glue on the surface of the glue-applying roller.

[0014] Preferably, a rotating ring is provided above the fixed base and the fixed base has a built-in rotating drive structure, and the axis of the conical head is located above the rotation trajectory of the conical base.

[0015] Based on the above technical solution, the rotation drive structure is an existing gear motor structure. Several bosses are evenly distributed circumferentially on the upper surface of the rotating ring, and the bottom of the conical seat adopts a groove structure. The groove matches the size and shape of the bosses. During installation, the conical seat can be inserted into the bosses for positioning, and further secured with bolts, connecting the conical seat and the bosses as one unit. Compared to the rotating ring, the bosses have the ability to rotate independently. In actual production, when dealing with casters of different bore diameters, simply loosen the bolts and disassemble and replace with a new model of conical seat adapted to the corresponding caster bore diameter. This improves the equipment's adaptability to diverse caster products, ensuring accurate center positioning in the production and processing of various casters, effectively improving production efficiency and product quality.

[0016] Preferably, a translation seat is provided below the drive box, and the translation seat is a lead screw structure.

[0017] Preferably, the drying chamber has an overall N-shaped structure, with one end connected to the central fixed seat of the rotary table, and a fan connected to the drying chamber is provided on the top of the drying chamber.

[0018] Preferably, the adhesive scraping assembly consists of a scraper and an electrically operated telescopic part.

[0019] Based on the above technical solutions, the translation seat is a lead screw structure driven by a motor, and the output end of the lead screw structure is connected to the bottom of the drive box; the drive box can be a motor that directly drives the flipping plate, or it can be set as a conventional cylinder-type structure that drives the flipping plate to rotate 90° vertically.

[0020] In summary, this application includes the following beneficial technical effects:

[0021] 1. In this utility model, a rotary table is set up to realize the batch glue application and transfer of casters. The positioning drive component and the conical seat limit the vertical position of the casters to ensure the stability of the casters during the glue application process. The glue application roller is brought into close contact with the casters during the rotation process by the translation seat to realize the automatic glue application operation.

[0022] 2. In this utility model, the glue frame can gather and collect the glue that drips from the glue box onto the surface of the glue roller, and the glue frame edge can achieve uniform distribution of the glue on the surface of the glue roller;

[0023] 3. This utility model has a simple structure. The rotating ring has several protrusions along its circumference, and the bottom of the conical seat has a groove structure. After the conical seat is inserted into the protrusions, it can be positioned and installed by bolts. Moreover, the protrusions can rotate relative to the rotating ring, so that the model of the conical seat can be disassembled and replaced to adapt to casters with different hole diameters for center positioning.
