Description

A coating oven drying device Technical Field

[0001] This utility model relates to the field of coating oven technology, specifically a coating oven drying device. Background Technology

[0002] Coating ovens are indispensable equipment in the coating process. Through precise temperature control and hot air circulation, they provide a stable drying environment for the coating materials, ensuring the drying effect of the coating at different stages. The drying unit, as the core component of the coating oven, accelerates solvent evaporation by optimizing the direction and angle of hot air, improving coating adhesion and surface quality. The synergistic effect of both not only increases production efficiency but also effectively reduces coating defects and lowers energy consumption. The combination of coating ovens and drying units provides a reliable guarantee for efficient, energy-saving, and high-quality production in the coating process, and is widely used in industries such as papermaking, batteries, and films, serving as a key link in improving the quality of coated products.

[0003] Coating oven drying devices can improve production efficiency, but they still have certain problems: 1) Uneven hot air distribution in traditional ovens leads to inconsistent drying effects; 2) Low hot air recovery efficiency results in high energy consumption; 3) The drying angle is not adjustable, making it unable to adapt to the needs of diverse coating materials; 4) A single drying zone cannot control the drying process in stages, resulting in low drying efficiency and unstable material properties. Therefore, in view of the above situation, there is an urgent need to develop a coating oven drying device to overcome the shortcomings in current practical applications and meet current needs. Summary of the Invention

[0004] The purpose of this invention is to provide a coating oven drying device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a coating oven drying device, comprising an oven, a coating material inserted into the oven, a hot air generating and circulating device installed at the top of the oven, several baffles installed below the hot air generating and circulating device for zoned heat insulation, and a hot air drying mechanism installed below the hot air generating and circulating device for heat source circulation.

[0006] The hot air drying mechanism includes a flexible air guide hose and an air guide assembly. The flexible air guide hose is connected to and fixed to the air inlet and outlet of the hot air generating and circulating device, and the air guide assembly is connected to and fixed to the bottom end of the flexible air guide hose.

[0007] The interior of the air duct is divided into two air channels along the direction of hot air flow, one for air outlet and the other for air return.

[0008] The air guiding assembly includes a housing, partition a, guide plate, diaphragm, and partition b. The housing is installed at the bottom of the air guiding hose. Partition a and partition b are both installed in the middle of the housing. The interior of the housing and partition a and partition b form two independent air ducts for air inlet and outlet. Two through slots are opened at the bottom edge of the housing. Guide plates for air inlet and outlet are hinged at both through slots. A diaphragm is installed between the guide plate and the housing.

[0009] Preferably, a primary drying zone is formed between the baffle and the oven inlet, a secondary drying zone is formed between two adjacent baffles, and a tertiary drying zone is formed between the baffle and the oven outlet. Specifically, by dividing the drying zone into multiple stages, a gradual drying process for the coating can be achieved. The primary drying zone is mainly responsible for the initial drying of the coating, removing most of the solvent; the secondary drying zone further distributes hot air evenly to ensure the uniformity of coating drying; and the tertiary drying zone is responsible for the deep drying and shaping of the coating to ensure that the final performance of the coating meets the requirements. This zoned design not only improves drying efficiency but also optimizes the drying quality of the coating. At the same time, by rationally distributing heat energy, it reduces energy consumption and the possibility of coating defects.

[0010] Preferably, a connecting rod assembly is installed on one side of the air guide hose, a screw is movably inserted through the top edge of the oven, a horizontal shaft is fixed at the bottom end of the screw, the top ends of several sets of connecting rod assemblies are fixedly connected to the horizontal shaft, and an adjusting nut is fitted on one end of the screw located on the upper surface of the oven. Specifically, by using the screw in conjunction with the adjusting nut and the horizontal shaft, the height of multiple sets of connected connecting rod assemblies can be adjusted simultaneously, thereby achieving uniform and rapid adjustment of the size of the air outlets of multiple sets of air guide assemblies.

[0011] Preferably, a connector is installed between two adjacent sets of air guide components for connection, and a suspension is installed between the connector and the hot air generating and circulating device for connection. Specifically, the connector and the suspension are used to fix the air guide components.

[0012] Preferably, the connecting rod assembly includes a connecting rod, a sliding shaft, and a bearing seat. The bearing seat is vertically fixed to one side of the housing, and the sliding shaft slides through the bearing seat. One end of the connecting rod is hinged to the bottom end of the sliding shaft, and the other end of the connecting rod is hinged to the edge of the guide plate. Both the guide plate and the connecting rod are provided in two sets. Specifically, the sliding shaft is pulled by a screw and an adjusting nut to adjust its height. When the height of the sliding shaft changes, it will drive the two guide plates on both sides of the housing, which are used for air inlet and outlet, to rotate around the hinge position through the two connecting rods, thereby adjusting the air inlet and outlet direction and avoiding problems such as uneven drying and coating surface quality caused by the angle of the hot air during the drying process.

[0013] Compared with the prior art, this utility model provides a coating oven drying device, which has the following features:

[0014] Beneficial effects:

[0015] This coating oven drying device significantly improves hot air utilization efficiency and drying uniformity through the design of multiple equidistantly distributed air guide components combined with a hot air output and recovery circulation system. The air outlet angle of the air guide components is adjustable, which can flexibly adapt to the drying needs of different coating materials and optimize the contact effect between hot air and the material surface. The gradient temperature control design of the three-stage drying zone (separated by baffles) realizes the fine control of the drying process, avoiding deformation or quality defects caused by sudden temperature changes. The overall structure is compact and has the dual advantages of energy saving and high-efficiency drying, making it suitable for high-precision and high-stability coating production processes.

[0028] Example:

[0029] Please refer to Figures 1-8. This utility model provides a technical solution: a coating oven drying device, including an oven 10, a coating material 20 inserted inside the oven 10, a hot air generating and circulating device 30 installed at the top inside the oven 10, several baffles 40 installed below the hot air generating and circulating device 30 for partitioned heat insulation, and a hot air drying mechanism 50 installed below the hot air generating and circulating device 30 for heat source circulation.

[0030] The hot air drying mechanism 50 includes a flexible air guide 510 and a guide assembly 520. The flexible air guide 510 is connected to and fixed to the air inlet and outlet of the hot air generating and circulating device 30, and the guide assembly 520 is connected to and fixed to the bottom end of the flexible air guide 510.

[0031] The interior of the air guide hose 510 is divided into two air ducts along the direction of hot air flow, one for air outlet and the other for air return.

[0032] The air guide assembly 520 includes a housing 521, a partition a 522, a guide plate 523, a soft membrane 524, and a partition b 525. The housing 521 is installed at the bottom end of the air guide hose 510. The partitions a 522 and b 525 are both installed in the middle of the housing 521. The interior of the housing 521 and the partitions a 522 and b 525 form two independent air ducts for air inlet and outlet. Two through slots are opened at the bottom edge of the housing 521. The guide plates 523 for air inlet and outlet are hinged at both through slots. The soft membrane 524 is installed between the guide plates 523 and the housing 521.

[0033] Preferably, a primary drying zone 410 is formed between the baffle 40 and the inlet of the oven 10, a secondary drying zone 420 is formed between two adjacent baffles 40, and a tertiary drying zone 430 is formed between the baffle 40 and the outlet of the oven 10. Specifically, by dividing the drying zone into multiple stages, the coating can be dried gradually. The primary drying zone 410 is mainly responsible for the initial drying of the coating and removing most of the solvent. The secondary drying zone 420 further distributes hot air evenly to ensure the uniformity of coating drying. The tertiary drying zone 430 is responsible for the deep drying and shaping of the coating to ensure that the final performance of the coating meets the requirements. This partitioned design not only improves drying efficiency but also optimizes the drying quality of the coating. At the same time, by rationally distributing heat energy, it reduces energy consumption and the possibility of coating defects.

[0034] Preferably, a connecting rod assembly 530 is installed on one side of the air guide hose 510, a screw 540 is movably inserted through the top edge of the oven 10, a horizontal shaft 542 is fixedly installed at the bottom end of the screw 540, the top ends of several sets of connecting rod assemblies 530 are fixedly connected to the horizontal shaft 542, and an adjusting nut 541 is sleeved on one end of the screw 540 located on the upper surface of the oven 10. Specifically, by using the screw 540 in conjunction with the adjusting nut 541 and the horizontal shaft 542, the height of multiple sets of connected connecting rod assemblies 530 can be adjusted simultaneously, thereby achieving uniform and rapid adjustment of the size of the air outlet of multiple sets of air guide assemblies 520.

[0035] Preferably, a connector 550 is installed between two adjacent sets of air guide assemblies 520 for connection, and a suspension 560 is installed between the connector 550 and the hot air generating and circulating device 30 for connection. Specifically, the connector 550 and the suspension 560 are used to fix the air guide assembly 520.

[0036] Preferably, the connecting rod assembly 530 includes a connecting rod 531, a sliding shaft 532, and a bearing seat 533. The bearing seat 533 is vertically fixed to one side of the housing 521, and the sliding shaft 532 slides through the bearing seat 533. One end of the connecting rod 531 is hinged to the bottom end of the sliding shaft 532, and the other end of the connecting rod 531 is hinged to the edge of the guide plate 523. Both the guide plate 523 and the connecting rod 531 are provided in two sets. Specifically, the sliding shaft 532 is pulled by the screw 540 in conjunction with the adjusting nut 541, thereby adjusting the height of the sliding shaft 532. When the height of the sliding shaft 532 changes, it will drive the two guide plates 523 on both sides of the housing 521 for air inlet and outlet to rotate around the hinge position through the two connecting rods 531 hinged to it, thereby achieving the effect of adjusting the air inlet and outlet direction and avoiding problems such as drying uniformity and coating surface quality caused by the angle of hot air during the drying process.

[0037] Working principle: The coating material 20 enters from one end of the oven 10, is dried by internal hot air, and exits from the other end. During the drying process, hot air is generated by the hot air generator and circulation device 30 and sequentially discharged through the air guide hose 510 and the air guide assembly 520. Each air guide assembly 520 is internally divided into independent inlet and outlet air channels, with two guide plates 523 responsible for the air intake or exhaust in two directions respectively. Adjacent air guide assemblies 520 form a hot air circulation. Different coating materials 20 have different drying requirements. At this time, the drying effect can be adjusted by adjusting the contact angle between the hot air and the coating material 20. Simply turn the adjusting nut 541. The adjusting nut 541 drives the screw 540 to rise and fall, which in turn drives the sliding shaft 532 of the multiple sets of connecting rod assemblies 530 to rise and fall in conjunction with the horizontal shaft 542. When the sliding shaft 532 rises and falls, it will work with the connecting rod 531 to drive the guide plate 523 to rotate around the hinge position, thereby realizing the adjustment of the angle of the air inlet and outlet. The interior of the drying oven 10 is divided into multiple drying zones by the baffle 40. The hot air drying mechanism 50 in each drying zone can be adjusted individually. The hot air generation and circulation device 30 can also be controlled to output heat sources of different temperatures to each drying zone, thereby achieving the effect of zoned temperature control drying.
