Description

Technical Field

[0001] This invention relates to the field of composite photocuring preparation technology, specifically to a slurry pretreatment coating machine. Background Technology

[0002] Composite light-curing agents, also known as light-cured composite resins, can closely match the color of natural teeth. They can also simulate the translucency of enamel and dentin through layered filling technology, resulting in a natural appearance after restoration. They are especially suitable for areas with high aesthetic requirements, such as anterior teeth. Through acid etching technology and special adhesives, light-cured composite resins can form a strong mechanical bond with tooth tissue, making them less prone to falling off. They can effectively seal the edges of the restoration, reduce microleakage, and require less healthy tooth tissue to be removed during restoration, thus preserving the tooth structure to the greatest extent possible. This is why they are widely used.

[0003] However, traditional composite photocuring agents have the following drawbacks: When producing composite photocurable agents, heat dissipation is required during the curing of the slurry. The curing reaction of many slurries, such as epoxy resin and MMA resin, is an exothermic process. If heat dissipation is not done properly, the local temperature may be too high, resulting in uneven curing speed or uncontrolled reaction, thus prolonging the overall curing time. Summary of the Invention

[0004] The purpose of this invention is to provide a slurry pretreatment coating machine to solve the problem mentioned in the background art that heat dissipation is required during the curing of composite photocurable agents. The curing reaction of many slurries, such as epoxy resin and MMA resin, is an exothermic process. If heat dissipation is not done properly, the local temperature may be too high, resulting in uneven curing speed or uncontrolled reaction, thus prolonging the overall curing time.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a slurry pretreatment coating machine, comprising a pretreatment frame, wherein a first placement unit, a second placement unit, a first micro-gravure coating head unit, a composite photocuring unit, a second micro-gravure coating head unit, and a winding unit are fixedly installed sequentially from left to right at the bottom end of the pretreatment frame; the composite photocuring unit comprises a curing frame and a composite rubber roller, one side of the bottom end of the inner wall of the curing frame is rotatably connected to one end of the composite rubber roller, a composite steel roller located on one side of the composite rubber roller is rotatably connected to the curing frame, a curing box is fixedly installed in the middle of the curing frame, and a pretreatment unit is fixedly connected to one side of the composite photocuring unit; the pretreatment unit comprises a cold air box and a cold air fan, the top end of the cold air box is fixedly connected to the bottom end of the cold air fan, and a cold air duct is fixedly connected to one side of the cold air box.

A large amount of heat is released during the curing process. To prevent damage to the finished product, the substrate is cooled by a pretreatment unit. Cold air is blown out by the lower and upper air nozzles. To meet the needs of substrates of different thicknesses and different process requirements, the gap is adjusted by adjusting rollers to optimize the film path.

Cold air is blown out from the lower and upper nozzles. To meet the needs of substrates of different thicknesses and different process requirements, the gap is adjusted by adjusting rollers and the film path is adjusted to the optimal state, which shortens the preparation time and improves the product qualification rate.

[0028] In this embodiment, the following steps are performed: one substrate is fed into a first feeding unit 1, and its surface is peeled off after traction; another substrate is fed into a second feeding unit 2, and its surface is peeled off after traction. The materials are first coated with slurry on a first micro-grooving coating head unit 3. Substrates A, B, and C are extruded through a composite steel roller 43 and a composite rubber roller 42 to form a semi-finished product D. Since any two of substrates A, B, and C have slurry on their surfaces, the semi-finished product D after lamination is semi-cured by an LED light and then UV-cured. The lamp is cured to form the final product D. During the curing process, a large amount of heat is released. To prevent damage to the finished product, the substrate is cooled by the pretreatment unit 8. Cold air is blown out from the lower and upper nozzles.
