Description

Technical Field

[0001] This utility model relates to the field of battery technology, and specifically to a suspended drying oven for a coating machine. Background Technology

[0002] In commercial power battery coating processes, traditional drying ovens are gradually being replaced due to limitations in contact drying and tension control. Suspension drying ovens, through air flotation technology, can achieve efficient, low-loss, and energy-saving drying effects, and have become the mainstream choice in high-end coating fields.

[0003] However, in actual operation, suspended drying ovens still face many challenges. Drying the coated wet substrate is a crucial step in the coating process. Traditional suspended drying ovens are typically monolithic structures, making it difficult to flexibly adjust to the coating process requirements of different products. This can easily lead to insufficient drying in some areas, resulting in incomplete drying, or over-drying in others, affecting product quality. Furthermore, the lack of effective protective measures when the substrate enters and exits the oven makes it prone to scratching against the inlet and outlet edges, damaging the substrate surface. Moreover, the vibration generated by the equipment's own fan and the disturbance caused by internal airflow can interfere with the stability of the oven. In addition, vibrations from surrounding equipment in the factory environment can be transmitted to the oven, causing slight shaking and displacement of the substrate during the drying process, further affecting the uniformity and smoothness of the coating and reducing the product yield. Utility Model Content

[0004] To address the technical problems in the prior art, this utility model provides a suspended drying oven for a coating machine, comprising several drying oven units. These units are independent of each other and sequentially connected along the direction of substrate movement. Each drying oven unit includes a base, multiple sets of shock-absorbing devices, and a box body. The box body is connected to the base via the multiple sets of shock-absorbing devices. The box body has an inlet and an outlet on both sides for the substrate to pass through. Each shock-absorbing device includes a crossbar, two pads, a damper, and two first springs. The crossbar is fixedly installed at the bottom of the box body, and the two pads are fixedly installed on the base. Both ends of the crossbar are fixedly connected to the upper ends of the two dampers, and the lower ends of the dampers are fixedly connected to the pads. The first springs are sleeved on the upper ends of the dampers, and both ends of the first springs abut against the bottom of the crossbar and the lower end of the dampers, respectively. The first springs expand and contract with the movement of fluid inside the dampers.

[0005] Furthermore, the shock absorption device also includes a slide rod, two slip rings, a second spring, and two support bars. The slide rod is fixedly installed between two pads, the two slip rings are slidably installed on the slide rod, the second spring is sleeved on the slide rod, and the two ends of the second spring are fixedly connected to the two slip rings respectively. The two support bars are symmetrically arranged, and the two ends of the support bars are hinged to the crossbar and the slip ring respectively.

[0006] Furthermore, a telescopic frame is fixedly installed at the bottom of the housing, which wraps around the multiple sets of shock-absorbing devices, and the telescopic frame is slidably connected to the base.

[0007] Furthermore, protective frames are fixedly installed on both sides of the box body. The two protective frames are respectively connected to the inlet and outlet. Two traction rollers are rotatably installed inside the protective frames, and the two traction rollers are respectively located on the upper and lower sides of the substrate.

[0008] Furthermore, the chamber is provided with an upper air chamber and a lower air chamber, and a gap space is formed between the upper air chamber and the lower air chamber to connect the inlet and the outlet. Multiple sets of air nozzles are distributed at the lower end of the upper air chamber and the upper end of the lower air chamber. The multiple sets of air nozzles are equally spaced along the moving direction of the substrate. The air nozzles are located in the gap space, and the air inlet of the air nozzle is connected to the upper air chamber or the lower air chamber through a wind equalization plate. The air outlets are all facing the substrate. One end of the upper air chamber and the lower air chamber is provided with an air inlet, and the two air inlets are connected to the heating box and the fan through air ducts. The top of the chamber is provided with an exhaust port that penetrates the interior.

[0009] Furthermore, a central control unit is installed at one end of the enclosure. The central control unit is located on one side of the two air inlets and is connected to the heating box and the fan respectively. The central control unit is used to regulate the heating intensity of the heating box and the wind speed of the fan, thereby flexibly adjusting the temperature inside the enclosure.

[0010] Furthermore, an inspection door is rotatably installed at the other end of the housing, and the inspection door is provided with an observation port.

[0011] Furthermore, mounting plates are symmetrically provided at both ends of the base, and two adjacent oven units are fixedly connected by the two mounting plates.

[0012] Beneficial effects:

[0013] 1. In this utility model, by setting up several oven units, flexible adjustments can be made according to the coating process requirements of different products. Combined with the setting of a shock absorption device including a crossbar, two pads, a damper and two first springs, vibration can be reduced, avoiding wear of the substrate due to shaking or displacement, ensuring stable transmission, guaranteeing coating quality, and improving product yield. Specifically, when a large piece of equipment near the oven unit starts up and generates strong vibration, the oven body vibrates accordingly. The fluid inside the damper generates resistance, and at the same time, the first spring is compressed to store energy. After the vibration ends, the first spring releases energy and pushes the oven body back to stability. Through the coordinated work of the damper and the first spring, the amplitude and duration of vibration can be suppressed.

[0014] 2. In this utility model, the arrangement of the sliding rod, two slip rings, a second spring, and two support bars can further reduce vibration and enhance the shock absorption effect. Specifically, when the box vibrates and moves downward, the crossbar drives the two support bars to make the two slip rings slide towards the middle on the sliding rod, compressing the second spring and storing its elastic potential energy. After the vibration ends, the second spring releases its energy to push the slip rings, support bars, and crossbar back to their original positions. The telescopic frame prevents dust and debris from entering the connection between the box and the base, ensuring the shock absorption performance of the shock absorption device and extending its service life.

[0015] 3. In this utility model, by setting up a protective frame and a traction roller, rolling friction can be used instead of sliding friction, reducing resistance, avoiding scratching between the substrate and the inlet and outlet edges, and protecting the surface of the substrate.

[0016] 4. In this utility model, the temperature of each chamber can be flexibly adjusted by setting up a heating box, a fan and a central control unit, so as to avoid the problem of insufficient or excessive drying of products and improve product quality and production efficiency.

[0017] 5. In this utility model, the inspection door can be easily opened to facilitate the maintenance and repair of the equipment and components inside the chamber. Combined with the observation port, it is easy to manually observe the operating status of the substrate inside the chamber. The observation port is made of high-temperature resistant transparent tempered glass. The mounting plate facilitates the disassembly and assembly of two adjacent oven units.

[0033] This utility model provides a suspended drying oven for a coating machine, such as... Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the device includes several drying oven units 1, which are independent of each other and sequentially connected along the direction of substrate movement. Each drying oven unit 1 includes a base 2, multiple sets of shock-absorbing devices 3, and a chamber 4. The chamber 4 is connected to the base 2 through the multiple sets of shock-absorbing devices 3. The chamber 4 has an inlet 5 and an outlet 6 on both sides for the substrate to pass through. The chamber 4 contains an upper air chamber 10 and a lower air chamber 11, forming a gap space between the upper air chamber 10 and the lower air chamber 11 that connects the inlet 5 and the outlet 6. Multiple sets of air nozzles 12 are distributed at the lower end of the upper air chamber 10 and the upper end of the lower air chamber 11. These air nozzles 12 are evenly spaced along the direction of substrate movement and are located within the gap space. The air inlets of the air nozzles 12 are connected to the upper air chamber 10 or the lower air chamber 11 through a uniform air distribution plate 13, and the air outlets are all directed towards the substrate. One end of each of the upper air chamber 10 and the lower air chamber 11 is provided with... The air inlet 14 is connected to the heating box 16 and the fan 17 via the air duct 15. The top of the box 4 is provided with an exhaust port 18 that penetrates the interior. For convenient circulation, an internal circulation fan can be installed at the air inlet 14 and an exhaust fan can be installed at the exhaust port 18. The shock absorption device 3 includes a crossbar 31, two pads 32, a damper 33 and two first springs 34. The crossbar 31 is fixedly installed at the bottom of the box 4. The two pads 32 are fixedly installed on the base 2. The two ends of the crossbar 31 are fixedly connected to the upper ends of the two dampers 33 respectively. The lower ends of the dampers 33 are fixedly connected to the pads 32. The first springs 34 are sleeved on the upper ends of the dampers 33, and the two ends of the first springs 34 abut against the bottom of the crossbar 31 and the lower end of the dampers 33 respectively. The first springs 34 expand and contract with the fluid movement inside the dampers 33.

[0034] In this embodiment, the arrangement of several oven units 1 allows for flexible adjustment according to the coating process requirements of different products. Combined with the shock absorption device 3, which includes a crossbar 31, two pads 32, a damper 33, and two first springs 34, vibration can be reduced, preventing wear on the substrate due to shaking or displacement, ensuring stable transmission, guaranteeing coating quality, and improving product yield. Specifically, when a large piece of equipment near the oven unit 1 starts and generates strong vibration, the chamber 4 vibrates accordingly. The fluid inside the damper 33 generates resistance, and the first springs 34 are compressed to store energy. After the vibration ends, the first springs 34 release energy, pushing the chamber 4 back to stability. Through the coordinated work of the damper 33 and the first springs 34, the amplitude and duration of vibration can be suppressed.

[0035] In this utility model, preferably, such as Figure 5 and Figure 6As shown, the shock absorption device 3 also includes a slide rod 35, two slip rings 36, a second spring 37, and two support bars 38. The slide rod 35 is fixedly installed between two pads 32. The two slip rings 36 are slidably installed on the slide rod 35. The second spring 37 is sleeved on the slide rod 35, and both ends of the second spring 37 are fixedly connected to the two slip rings 36 respectively. The two support bars 38 are symmetrically arranged, and both ends of the support bars 38 are hinged to the crossbar 31 and the slip rings 36 respectively. A telescopic frame 7 is also fixedly installed at the bottom of the housing 4. The telescopic frame 7 is wrapped around the multiple sets of shock absorption devices 3, and the telescopic frame 7 is slidably connected to the base 2.

[0036] In this embodiment, the arrangement of the slide rod 35, two slip rings 36, second spring 37, and two support bars 38 can further reduce vibration and enhance the shock absorption effect. Specifically, when the housing 4 vibrates and moves downward, the crossbar 31 drives the two support bars 38 to make the two slip rings 36 slide towards the middle on the slide rod 35, compressing the second spring 37 and storing its elastic potential energy. After the vibration ends, the second spring 37 releases energy to push the slip rings 36, support bars 38, and crossbar 31 back to their original positions. The telescopic frame 7 can prevent dust and debris from entering the connection between the housing 4 and the base 2, ensuring the shock absorption performance of the shock absorption device 3 and extending its service life.

[0037] In this utility model, preferably, such as Figure 3 and Figure 4 As shown, protective frames 8 are fixedly installed on both sides of the box 4. The two protective frames 8 are respectively connected to the inlet 5 and the outlet 6. Two traction rollers 9 are rotatably installed inside the protective frames 8. The two traction rollers 9 are respectively located on the upper and lower sides of the substrate.

[0038] In this embodiment, by setting up the protective frame 8 and the traction roller 9, rolling friction can be used instead of sliding friction, reducing resistance, preventing the substrate from scratching the edges of the inlet 5 and outlet 6, and protecting the surface of the substrate.

[0039] In this utility model, preferably, such as Figure 2 and Figure 3 As shown, a central control unit 19 is also installed at one end of the housing 4. The central control unit 19 is located on one side of the two air inlets 14. The central control unit 19 is connected to the heating box 16 and the fan 17 respectively. The central control unit 19 is used to regulate the heating intensity of the heating box 16 and the wind speed of the fan 17, thereby flexibly adjusting the temperature inside the housing 4. In specific installation, the heating box 16, the fan 17 and the central control unit 19 are located at the rear end of the oven unit 1.

[0040] In this embodiment, the connection between the heating box 16, the fan 17 and the central control unit 19 allows for flexible adjustment of the temperature of each box 4, avoiding problems of insufficient or excessive drying of the product and improving product quality and production efficiency.

[0041] In this utility model, preferably, such as Figure 1 and Figure 2 As shown, an inspection door 20 is rotatably installed at the other end of the box body 4. The inspection door 20 is provided with an observation port 21. Specifically, the inspection door 20 is located at the front end of the box body 4. Mounting plates 22 are symmetrically provided at both ends of the base 2. Two adjacent oven units 1 are fixedly connected by two mounting plates 22.

[0042] In this embodiment, the inspection door 20 can be easily opened to facilitate the maintenance and repair of the equipment and components inside the chamber 4. Combined with the observation port 21, it is easy to manually observe the operating status of the substrate inside the chamber 4. The observation port 21 is made of high-temperature resistant transparent tempered glass. The mounting plate 22 facilitates the disassembly and assembly of two adjacent oven units 1.

[0043] Working principle:

[0044] like Figures 1 to 6 As shown, after the equipment is started, the fan 17 sends air into the heating chamber 16. The hot air, heated to the set temperature, enters the upper air chamber 10 and the lower air chamber 11 through the air duct 15 and the air inlet 14. The hot air first diffuses naturally in the air chamber, initially distributing evenly. Then, it is rectified by the air distribution plate 13 to make the airflow stable and uniform. Subsequently, it is sprayed at high speed onto the surface of the substrate from the slit of the air nozzle 12 to dry the substrate. The air outlet at the top of the chamber 4 is used to discharge the hot air inside the chamber 4 and maintain the airflow circulation inside the chamber 4. During the drying process, the substrate passes through the protective frames 8 of the inlet 5 and outlet 6 on both sides of the chamber 4. Two rotatable traction rollers 9 are installed inside the protective frames 8 to reduce the resistance of the substrate when entering and exiting the chamber 4 through rolling friction, preventing the substrate from scratching the edges of the inlet and outlet 6 and ensuring the quality of the substrate. To reduce the impact of vibration on the drying process, multiple sets of shock-absorbing devices 3 are installed between the chamber 4 and the base 2. When the chamber 4 vibrates, the damper 33 in the shock-absorbing device 3 uses internal fluid or damping medium to generate resistance, converting the mechanical energy of the vibration into heat energy and suppressing the vibration amplitude and duration. The first spring 34 compresses and stores energy during vibration and releases energy to push the chamber 4 back to its original position after the vibration disappears. In addition, when the chamber 4 vibrates and moves downward, the crossbar 31 drives the support bar 38 to make the slip ring 36 slide towards the middle on the slide rod 35, compressing the second spring 37 to store elastic potential energy. After the vibration ends, the second spring 37 releases energy to push the slip ring 36, support bar 38 and crossbar 31 back to their original positions, thereby effectively reducing the vibration of the chamber 4, ensuring the stability of the substrate during the drying process, ensuring the coating is uniform and flat, and improving the drying quality and product yield.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
