Description

Technical Field

[0001] This invention relates to the field of adhesive curing technology, and more specifically to a rotary curing box. Background Technology

[0002] In modern industrial manufacturing, many rotating workpieces (such as pipes, cylinders, and housings) require the application of adhesives or sealants to their inner surfaces during assembly to achieve functions such as bonding, sealing, or vibration damping between parts. For example, in applications such as the mating surfaces of automobile engine cylinder blocks and cylinder heads, hydraulic pipeline joints, and the mating surfaces of bearing housings and housings, a layer of adhesive needs to be uniformly applied to the inner surface and cured by heating to obtain reliable bonding strength and sealing performance.

[0003] However, current curing processes for coating the inner wall of workpieces generally suffer from problems such as uneven adhesive layer thickness, unstable curing quality, and low production efficiency, making it difficult to meet the requirements of modern manufacturing for the quality of inner wall coating and production cycle. Summary of the Invention

[0004] The purpose of this invention is to solve the technical problems of uneven adhesive layer thickness, unstable curing quality, and low production efficiency in existing adhesive curing processes, and to provide a rotary curing box.

[0005] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows: A rotary curing chamber includes a chamber body, the interior of which is divided into an air heating zone, a rotary curing zone and a hot air supply zone from top to bottom. The air heating zone and the hot air supply zone are connected by an air duct. The air heating zone is equipped with an electric heating tube for heating the air; The rotary curing zone is equipped with multiple rotating components; After the inner cavity of the workpiece is coated with adhesive, it is placed on the rotating assembly, which drives the workpiece to rotate. At the same time, the electric heating tube heats the air in the air heating zone and delivers it to the hot air supply zone through the air duct. The heated air passes through the rotating curing zone from bottom to top, heating and curing the adhesive inside the workpiece.

[0006] Furthermore, multiple rotating components are provided on both sides of the rotating curing area of ​​the box body; The side of the box is provided with a material loading and unloading port corresponding to the rotating component, and a protective door is provided at the material loading and unloading port.

[0007] Furthermore, the rotating assembly includes a support frame fixed inside the housing, and a plurality of pairs of parallel rotating rollers are rotatably mounted on the top of the support frame; The end of the rotating roller is equipped with a gear, and the gears of two adjacent rotating rollers are driven by a synchronous belt; One end of the rotating roller is connected to the output shaft of the reducer. The reducer is located outside the housing and connected to the side of the housing. The input shaft of the reducer is connected to the output shaft of the drive motor.

[0008] Furthermore, the spacing between adjacent pairs of rotating rollers is different.

[0009] Furthermore, the box body is provided with an upper partition and two lower partitions symmetrically distributed on both sides of the box body and located below the rotating assembly; A baffle is provided between the lower partition and the bottom of the box, and the baffle and the lower partition divide the inside of the box into a rotary curing area and a hot air supply area; The upper partition divides the interior of the chamber into an air heating zone and a rotary curing zone; Both the upper and lower partitions have multiple through holes.

[0010] Furthermore, the housing is equipped with two air supply ducts, the top of which passes through the upper partition and connects to the air heating zone. The air heating zone is equipped with a blower located at the top of the air supply duct. The bottom of the air duct passes through the lower partition and connects to the hot air delivery area.

[0011] Furthermore, an exhaust vent is provided on the top of the box body on the side away from the air supply duct, and an exhaust duct is provided on the outside of the box body at the exhaust vent, with an exhaust fan in the middle of the exhaust duct.

[0012] Furthermore, the top of the housing is provided with an air inlet that communicates with the air heating zone, and a check valve is provided at the air inlet.

[0013] Furthermore, the side of the housing is provided with a shell covering the outside of the reducer and drive motor, and the shell is provided with an inspection door.

[0014] Furthermore, the rotating roller is covered with a heat-resistant silicone coating.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The rotary curing chamber provided by the present invention drives the workpiece to rotate continuously through the rotating component, so that the adhesive on the inner wall is evenly distributed under the combined action of centrifugal force and gravity; at the same time, the heated hot air passes through the rotary curing zone from bottom to top, and heats the inner wall of the workpiece in all directions evenly, avoiding the problems of uneven adhesive layer thickness, local over-curing or under-curing caused by traditional fixed curing, and significantly improving the consistency and reliability of curing quality.

[0016] 2. The rotary curing chamber provided by the present invention is divided into an air heating zone, a rotary curing zone and a hot air supply zone from top to bottom. Hot air is delivered from the bottom through the air supply pipe and penetrates the inner cavity of the workpiece from bottom to top, forming a reasonable heat flow path, which has high heat energy utilization and good curing effect.

[0017] 3. The rotary curing box provided by the present invention has different spacing between two adjacent pairs of rotating rollers, which can be adapted to rotating workpieces of different diameters (such as pipes, cylinders, etc. of different diameters). One device can meet the curing requirements of multiple workpieces, reducing the equipment investment cost.

[0018] 4. The rotary curing box provided by the present invention has a heat-resistant silicone coating on the outside of the rotating roller. On the one hand, it increases the friction between the roller and the workpiece and prevents the workpiece from slipping. On the other hand, the silicone material is soft, which avoids the metal roller from scratching the inner wall surface of the workpiece. It also has excellent high temperature resistance and is suitable for long-term high temperature curing environment. Attached Figure Description
