Description

Technical Field

[0001] This utility model belongs to the field of water rhinestone production technology, and specifically relates to an auxiliary curing device for a polishing roller. Background Technology

[0002] Rhinestones are a type of jewelry made by cutting glass into diamond facets. This material is popular because it is relatively inexpensive and has a dazzling, diamond-like appearance, making it widely used in low- to mid-range jewelry designs. Therefore, rhinestone production is primarily done in batches. In fully automated rhinestone production, the processing involves steps such as powder application, rhinestone mounting, grinding, polishing, and unloading. These processes can be achieved using a grinding and polishing machine, which typically includes four grinding rollers and four polishing rollers.

[0003] Existing water-drilling polishing rollers include a cylindrical carbon steel grinding wheel base and a polishing roller sleeved on the outside and arranged along its axial direction. The polishing roller is made of cerium oxide polishing powder, phenolic resin, etc., and has the advantages of long service life and high polishing surface flatness. The polishing roller has a cylindrical structure and is bonded to the carbon steel grinding wheel base with resin adhesive.

[0004] For example, patent application number CN202111399041.9 discloses a method for preparing a polishing roller, the method comprising:

[0005] S101: Mix 805 resin, polishing powder and additives in sequence according to the formula. The additives include accelerator, curing agent, dibutyl phthalate and magnesium sulfate. Stir at room temperature for 10-20 minutes to obtain the casting liquid.

[0006] S102: Apply release oil to the molding die.

[0007] S103: Add the casting liquid to the molding mold, and stir the top of the casting liquid before filling the molding mold.

[0008] S104: After pouring, let stand at room temperature for 40-75 minutes.

[0009] S105: Remove the product and inner mold together from the outer mold.

[0010] S106: After standing at room temperature for 100-150 minutes, separate the product from the inner mold.

[0011] S107: Perform finishing work on the product.

[0012] In existing technologies, polishing rollers can be cured at room temperature, typically 20-30°C. At lower temperatures, such as 0°C, the curing time is extremely long, requiring several hours – 2-4 times the standard time – significantly impacting production efficiency. Existing technologies also allow for curing of the molding die and its polishing roller in an oven at low temperatures. However, this requires two-stage curing (usually vertical placement), necessitating a large oven and multiple transfers, making the process complex. Furthermore, the two curing stages are inconvenient for transporting the molding die and its polishing roller. Utility Model Content

[0013] To address the aforementioned problems, this utility model provides an auxiliary curing device for a polishing roller. Since the curing temperature requirements for polishing rollers are not high (the temperature itself is not high, and the control precision is not high), this embodiment designs a movable heating structure that can accelerate the curing process at low temperatures. The technical solution is as follows:
