Description

Technical Field

[0001] This utility model relates to the field of circulating oven technology, specifically an energy-saving hot air circulating oven for dispensing and curing adhesives. Background Technology

[0002] Adhesive potting and curing is a process in which liquid adhesive is poured into products, components, or electronic devices that need to be sealed, insulated, or protected. After potting, the product usually needs to be cured, which requires the use of a circulating oven to accelerate the curing process of the adhesive by heating the oven itself.

[0003] For example, patent CN221975658U discloses a hot air circulating oven, including a collection component. This component can collect medicines accidentally dropped during tray handling, reducing unnecessary waste. The recycling of medicines is simple and convenient, allowing for better weight control and reducing the inconvenience of secondary weighing, thus improving the overall effect. A protective component can detect the temperature of the tray surface between tray handling operations, providing a good warning effect to prevent worker injuries and making work safer and more efficient, facilitating widespread use. However, when using the oven body, the size and volume of the products to be dried vary, resulting in different internal moisture content and distribution. Larger products often have greater mass and thicker structures, and the path for moisture to migrate from the inside to the surface and evaporate is longer and more difficult. Therefore, the oven body cannot easily adjust the airflow according to different product sizes, which may lead to incomplete drying or significant energy waste in the long run.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on the existing hot air circulating oven. Utility Model Content

[0005] The purpose of this invention is to provide an energy-saving hot air circulating oven for dispensing and curing, in order to solve the problem mentioned in the background art that the oven body is difficult to adjust the air volume according to products of different sizes, which may cause incomplete drying of products or large-scale energy waste during long-term use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving hot air circulating oven for dispensing and curing adhesives, comprising a base, a conveying module disposed inside the base, a drive motor disposed on one side of the conveying module, and an oven body mounted on the top of the base;

[0007] Air outlets are provided on both sides inside the oven body. A heating chamber is installed on the top of the oven body. A fan is installed on the top of the heating chamber. The exhaust port of the fan is connected to the interior of the heating chamber.

[0008] Support frames are installed on both sides of the top of the base, and a swing rod is rotatably connected between the two support frames. Rolling wheels are installed at the bottom of the swing rod.

[0009] The drive shaft of the swing arm is equipped with an exhaust regulating mechanism for adjusting the air volume of the air outlet.

[0010] Furthermore, the adjustment mechanism includes a crank, which is fixedly connected to both ends of the drive shaft of the swing arm. One end of the crank is rotatably connected to a first connecting rod. Four sliding blocks are slidably connected to the inner wall of the oven body. The four sliding blocks cover the air outlet respectively. The sliding blocks on the same side are fixedly connected to each other by a connecting strip. One end of the first connecting rod is rotatably connected to a sliding block on one side.

[0011] Furthermore, the drive shaft of the swing arm is also equipped with an air intake adjustment mechanism for adjusting the air intake volume of the fan.

[0012] Furthermore, the air intake adjustment mechanism includes a second connecting rod, which is fixedly connected to the outer wall of the drive shaft of the swing rod. One end of the second connecting rod is rotatably connected to a reserved connecting block. The air inlet of the fan is rotatably connected to an adjustment plate. A pulley is fixedly connected to the drive shaft of the adjustment plate. A tension spring is installed on the top of the heating chamber. A rope is connected to the top of the tension spring. The rope passes around the pulley and is fixedly connected to the reserved connecting block.

[0013] Furthermore, the oven body is equipped with baffle curtains on both the front and rear sides.

[0014] Furthermore, the oven body has a hollow interior structure, and a connecting pipe is provided between the oven body and the heating chamber.

[0015] Furthermore, a guide plate is installed at the bottom of each of the four sliding blocks.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This energy-saving hot air circulating oven for dispensing and curing uses a swing arm to oscillate as products of different heights enter the oven body via the conveyor module. The swing arm, through a crank and connecting rod transmission structure, automatically adjusts the size of the air outlet opening, thereby precisely controlling the airflow according to the product size. This adaptive airflow adjustment method avoids unnecessary energy consumption, achieves precise energy utilization, and effectively reduces energy waste.

[0018] Furthermore, the rotation of the swing arm can also drive the air intake adjustment mechanism to work. The rotation of the swing arm drive shaft can also adjust the opening size of the fan air inlet through ropes, pulleys and other structures, and control the air intake volume, making the equipment adjustment more convenient and flexible, and able to quickly adapt to different potting products.

[0019] Furthermore, the air volume of the air outlet and air inlet is automatically adjusted by swinging the swing arm, enabling the equipment to adapt to different sizes of glue-pouring products without manual adjustment. The equipment can automatically optimize the hot air supply according to the actual situation of the product, improving the versatility and adaptability of the equipment. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1: Please refer to Figures 1-7 This utility model provides the following technical solution: an energy-saving hot air circulating oven for dispensing and curing adhesives, comprising a base 1, a conveying module 15 disposed inside the base 1, a drive motor disposed on one side of the conveying module 15, and an oven body 2 mounted on the top of the base 1; air outlets 9 are provided on both sides inside the oven body 2, a heating chamber is mounted on the top of the oven body 2, a fan 6 is mounted on the top of the heating chamber, and the exhaust port of the fan 6 is connected to the interior of the heating chamber; support frames 3 are mounted on both sides of the top of the base 1, and the two support frames 3 are rotatably connected. A swing rod 4 is provided, with a rolling wheel installed at its bottom. An exhaust adjustment mechanism for adjusting the air volume of the air outlet 9 is provided on the drive shaft of the swing rod 4. The exhaust adjustment mechanism includes a crank 5, which is fixedly connected to both ends of the drive shaft of the swing rod 4. One end of the crank 5 is rotatably connected to a first connecting rod 7. Four sliding blocks 8 are slidably connected to the inner wall of the oven body 2. The four sliding blocks 8 cover the air outlet 9 respectively. The sliding blocks 8 on the same side are fixedly connected to each other by a connecting strip. One end of the first connecting rod 7 is rotatably connected to a sliding block 8 on one side.

[0030] The conveying module 15 inside the base 1, driven by the drive motor, conveys the glued product into the oven body 2 for curing. The fan 6 at the top of the oven body 2 sends air into the heating chamber. The heated air enters the oven body 2 through the air outlets 9 on both sides, providing the necessary heat for curing the glued product. When using the oven body 2, the product is placed on the conveying module 15 for conveying. When the product's height exceeds the height set by the swing arm 4, the product's continued forward movement will cause the swing arm 4 to swing. At this time, the rollers on the swing arm 4 assist in moving along the product... The surface oscillates, and when the swing rod 4 oscillates, the crank 5 fixed at both ends of the drive shaft of the swing rod 4 will rotate accordingly. The crank 5 drives the first connecting rod 7, which is rotatably connected to it, to move. One end of the first connecting rod 7 is rotatably connected to the sliding block 8 on one side. Since the sliding blocks 8 on the same side are fixedly connected by a connecting strip, the movement of the first connecting rod 7 will drive the sliding block 8 to slide on the inner wall of the oven body 2. The sliding block 8 covers the air outlet 9. By sliding the sliding block 8, the opening size of the air outlet 9 can be changed, thereby realizing the adjustment of the air volume of the air outlet 9 according to different product sizes and reducing energy waste.

[0031] Example 2: Based on Example 1, an air intake adjustment mechanism is also disclosed, the specific structure of which is as follows:

[0032] The air intake adjustment mechanism includes a second connecting rod 10, which is fixedly connected to the outer wall of the drive shaft of the swing rod 4. One end of the second connecting rod 10 is rotatably connected to a reserved connecting block 16. The air inlet of the fan 6 is rotatably connected to an adjusting plate 14. A pulley 12 is fixedly connected to the drive shaft of the adjusting plate 14. A tension spring 13 is installed on the top of the heating chamber. A rope 11 is connected to the top of the tension spring 13. The rope 11 passes around the pulley 12 and is fixedly connected to the reserved connecting block 16. Baffle curtains 201 are provided on both the front and rear sides of the oven body 2. The interior of the oven body 2 is a hollow structure, and a connecting pipe 202 is provided between the oven body 2 and the heating chamber. A guide plate 801 is installed at the bottom of each of the four sliding blocks 8.

[0033] When the drive shaft of the swing rod 4 rotates, the second connecting rod 10 fixed to its outer wall will rotate accordingly. When the second connecting rod 10 rotates, it drives the reserved connecting block 16 connected to it to move. The movement of the reserved connecting block 16 is transmitted through the rope 11. The rope 11 passes around the pulley 12 and is connected to the tension spring 13. The oven body 2 is fixed on the drive shaft of the adjusting plate 14. The pulling of the rope 11 will cause the adjusting plate 14 to rotate around its drive shaft. When the adjusting plate 14 rotates, it changes the opening size of the air inlet of the fan 6, thereby realizing the adjustment of the air intake of the fan 6. The function of the tension spring 13 is to provide a force so that the adjusting plate 14 can return to the initial position when the tension of the rope 11 is removed. The hollow structure provides space for hot air circulation. The hot air heated in the heating chamber enters the oven body 2 through the connecting pipe 202 and circulates inside the oven body 2, providing uniform heat to the glued product and achieving the purpose of glue curing. The setting of the baffle curtain 201 can reduce the heat loss inside the oven body 2 and play a role in heat preservation. At the same time, when the conveying module 15 transports the glued product into and out of the oven body 2, the baffle curtain 201 can block the entry of cold air from the outside, maintain the stability of the internal temperature of the oven body 2, and improve energy utilization efficiency. Guided by the guide plate 801, the hot air can act more effectively on the glued product, improving the effect and uniformity of glue curing.
