Description

TECHNICAL FIELD

[0001] The utility model belongs to a kind of drying equipment, and particularly to a three-dimensional oven. BACKGROUND

[0002] After the existing liquid crystal display screen, glass element or thin film switch element is glued or inked, the glue or ink needs to be dried, and the precision of such elements is high, so the product needs to be placed on a tray during drying, and then the tray is placed in an oven for drying. There are two main drying methods. One is a tunnel dryer, such as the glue drying device disclosed in application number 202222690874.7, which transports products into a heating box via a conveyor belt and outputs them after a sufficient period of time in the heating box. This method requires a large amount of space for the entire drying device, and the drying efficiency and heat utilization rate are low. The other is a box type, such as the liquid crystal display screen drying and curing equipment disclosed in application number 202410885430.X, which places the product in a drying box for a certain period of time before cooling. This method dries a single product at a time, resulting in low drying efficiency. SUMMARY

[0003] The utility model aims to provide a three-dimensional oven that can solve at least one of the above problems.

[0004] According to one aspect of the utility model, a three-dimensional oven is provided, which includes a rack, a box, a feeding mechanism, a discharging mechanism, a material moving mechanism, a heating device, and a cooling device. The box is arranged on the rack, and the box includes a drying box and a cooling box. The heating device is arranged on the drying box, and the cooling device is arranged on the cooling box. One side of the drying box is provided with an inlet, and the cooling box is located on the other side of the drying box. One side of the cooling box is provided with an outlet. The feeding mechanism is arranged corresponding to the drying box, and the discharging mechanism corresponds to the cooling box. The material moving mechanism is arranged on the top of the box, and corresponds to the top of the drying box and the top of the cooling box.

[0005] The beneficial effects of this utility model are as follows: By placing the inlet at the drying chamber and the outlet at the cooling chamber, and with the transfer mechanism located at the top of the chamber, the products to be baked in the trays are placed into the drying chamber by the feeding mechanism, and drying is achieved within the drying chamber. Furthermore, the feeding mechanism allows the trays to be gradually stacked upwards, enabling simultaneous baking of multiple trays of products within the drying chamber. After baking, the transfer mechanism moves the trays from the top into the cooling chamber. The unloading mechanism facilitates the removal of the cooled products stacked at the bottom of the cooling chamber one by one. Thus, the gradual upward stacking of the trays in the drying chamber provides sufficient drying time for the products, while the gradual downward dropping of the trays in the cooling chamber provides sufficient cooling time, significantly reducing the space occupied by the entire chamber. Simultaneously, multiple products can be continuously baked, fully utilizing heat energy and greatly reducing energy consumption.

[0006] In some embodiments, the heating device includes a fan, a heating chamber, and heating pipes. The fan is fixed to the outside of the drying chamber and above the heating chamber, which is also fixed to the outside of the drying chamber. The fan's outlet is connected to the heating chamber. The heating pipes are located inside the heating chamber. Multiple ventilation holes are provided on the side wall of the drying chamber, and the heating chamber is connected to the drying chamber through these ventilation holes. The heating devices are located on opposite sides of the drying chamber. Thus, the fan can blow the upward-flowing heat from the heating chamber downwards and into the drying chamber through the ventilation holes, ensuring uniform heat distribution within the drying chamber and facilitating even drying of the product.

[0007] In some embodiments, the 3D oven further includes a support frame and limiting rods. The support frame is located at the bottom of the drying chamber, and limiting rods are provided inside both the drying chamber and the cooling chamber. Multiple limiting rods are arranged along the height direction of the drying chamber and the cooling chamber, and each limiting rod has a flow strip on its inner side. An anti-reverse assembly is provided on the support frame. Thus, the limiting rods can limit the outer periphery of the material trays, facilitating their stacking; the anti-reverse assembly provides support for the material trays inside the drying chamber and ensures that the material trays can enter normally from the feed inlet.

[0008] In some embodiments, the feeding mechanism includes a feeding rack, a first lifting device, a front-to-back moving device, and a first lifting device. The feeding rack is located on one side of the machine frame. The first lifting device and the front-to-back moving device are both mounted on the feeding rack. The first lifting device is mounted on the machine frame and located below the drying chamber. The front-to-back moving device is connected to the first lifting device. One end of the front-to-back moving device corresponds to the feed inlet of the drying chamber. The top end of the first lifting device can penetrate the bottom of the drying chamber and extend into the drying chamber. The top end of the first lifting device corresponds to the anti-reverse component. Thus, by providing the first lifting device, the tray can be transported from below to above, facilitating product placement on the tray. Then, the front-to-back moving device transports the tray with the product placed on it into the oven. Finally, the first lifting device pushes the tray upwards, facilitating its placement on the anti-reverse component inside the drying chamber. This achieves automatic tray feeding, eliminating the need for manual placement of the tray into the drying chamber, saving labor and feeding time, and improving production efficiency.

[0009] In some embodiments, the first lifting device includes a drive motor, a lifting plate, lifting rods, and support rods. The drive motor is mounted on the frame, the lifting plate is connected to the output shaft of the drive motor, and multiple lifting rods are mounted on the lifting plate. The lifting rods pass through the bottom of the drying chamber and extend into the drying chamber. The two ends of the support rods are fixed to the top of the lifting rods. Thus, the material trays fed in through the feed inlet can be supported by the lifting rods and support rods, and then, under the action of the drive motor, they are pushed upwards and stacked below the raw material trays inside the drying chamber. They are supported by the anti-reverse assembly, facilitating the input of the next material tray.

[0010] In some embodiments, the first lifting device includes a lifting frame, and the forward and backward moving device includes a forward and backward moving motor, a forward and backward moving synchronous belt, and forward and backward moving synchronous pulleys. The forward and backward moving motor is mounted on the lifting frame, and there are two forward and backward moving synchronous pulleys. One of the pulleys is mounted on the output shaft of the motor, and the other is mounted on the lifting frame. The forward and backward moving synchronous belt is mounted on the two pulleys and corresponds to the feed inlet. Thus, through the forward and backward moving device and the forward and backward moving motor, the forward and backward moving synchronous belt can be driven to convey material, thereby transporting the material tray on the belt forward and moving it into the drying chamber.

[0011] In some embodiments, the unloading mechanism includes an unloading frame, a stop device, a second lifting device, a second lifting device, a first front-rear conveying device, and a second front-rear conveying device. The unloading frame is located on the other side of the machine frame. The second lifting device and the first front-rear conveying device are mounted on the unloading frame. The second front-rear conveying device is located on one side of the first front-rear conveying device and is located inside the cooling box. The second lifting device is located below the cooling box, with its top end penetrating the bottom of the cooling box and extending inward. The stop device is located on both sides of the second front-rear conveying device. Both the stop device and the second front-rear conveying device are located inside the cooling box, and the first front-rear conveying device corresponds to the outlet of the cooling box. Thus, when the lifting device lifts the tray upward and moves it downward to a certain position, the stop device blocks the other trays, ensuring that the lifting device can only lower one tray onto the second front-rear conveying device. This facilitates the movement of the cooled product from the tray to the first front-rear conveying device by the second front-rear conveying device, achieving automatic output of the trays from below without manual operation, greatly saving manpower and avoiding frequent opening of the oven door, thus improving efficiency.

[0012] In some embodiments, the structure of the second lifting device is the same as that of the first lifting device. The stop device includes a cylinder and a baffle. The cylinder is located inside the cooling box, and the baffle is connected to the cylinder and located above the second front and rear conveying device. The support rod of the second lifting device is located between the baffles on both sides. Thus, the cylinder can push the baffle to move towards the second front and rear conveying device, thereby separating the material trays above and below the baffle, facilitating the material trays to fall one by one onto the second front and rear conveying device.

[0013] In some embodiments, the 3D oven further includes a tray circulation mechanism, which comprises a circulation frame, a first motor, and a tray conveyor belt. The circulation frame is fixed to the machine frame and located below the oven body. The first motor is fixed to the machine frame. The tray conveyor belt is mounted on the circulation frame and connected to the output shaft of the first motor. One end of the tray conveyor belt corresponds to the first front-rear conveying device, and the other end corresponds to the front-rear moving device. The circulation frame is located below the first lifting device and the second lifting device. Thus, the tray circulation mechanism facilitates the automatic conveying of trays output from the cooling chamber. After the product is removed, it is conveyed to the tray circulation mechanism via the first front-rear conveying device, and then to the front-rear moving device for easy product placement, thereby achieving automatic tray conveying.

[0014] In some embodiments, the cooling device includes axial flow fans located on opposite sides of the cooling chamber, which is separated from the drying chamber by a partition. Thus, the convection of the axial flow fans increases the airflow velocity, enabling rapid cooling of the products in the trays within the cooling chamber. Attached Figure Description

[0030] The present invention will now be described in further detail with reference to the accompanying drawings.

[0031] Reference Figures 1-4 The three-dimensional oven includes a frame 1, a housing 2, a feeding mechanism 3, a discharging mechanism 4, a transferring mechanism 5, a heating device 6, and a cooling device 7. The housing 2 is mounted on the frame 1 and includes a drying chamber 21 and a cooling chamber 22. The heating device 6 is mounted on the drying chamber 21, and the cooling device 7 is mounted on the cooling chamber 22. The drying chamber 21 has a feeding port 211 on one side, and the cooling chamber 22 is located on the other side of the drying chamber 21. The cooling chamber 22 has a discharging port 221 on one side. The feeding mechanism 3 is correspondingly arranged with the drying chamber 21, and the discharging mechanism 4 is correspondingly arranged with the cooling chamber 22. The transferring mechanism 5 is located on the top of the housing 2 and corresponds to the top of the drying chamber 21 and the top of the cooling chamber 22.

[0032] In the use of this utility model's three-dimensional oven, to facilitate product drying within the drying chamber 21 and prevent scratches, the products are placed in a tray, and then the tray is placed into the drying chamber 22. Products such as glass components, membrane switches, and LCD displays are placed into the tray at the feeding mechanism 3. The trays are conveyed into the drying chamber 21 via the feeding mechanism 3 through the inlet 211, and gradually stacked from bottom to top. This allows for a continuous inflow of trays into the inlet 211, while simultaneously heating and drying the products within the entire stack of trays without extending the heating channel, significantly reducing the volume of the drying chamber and improving drying efficiency. When the trays gradually rise to the top of the drying chamber 21, the products are dried. At this point, the transferring mechanism 5 clamps and moves the top tray into the cooling chamber 22. To facilitate the movement of the tray from the drying chamber 21 to the cooling chamber 22, a connecting hole 213 is provided at the top of the drying chamber 21 near the cooling chamber 22. This allows the tray to be moved into the cooling chamber 22 through the connecting hole 213 while being held by the material transfer mechanism 5. The tray moves from top to bottom within the cooling chamber 22. When it reaches the outlet 221, the product in the tray has cooled to room temperature. When the tray reaches the outlet 221, the unloading mechanism 4 removes the tray from the cooling chamber 22, facilitating the removal of the baked product and completing the baking process.

[0033] The heating device 6 includes a fan 61, a heating chamber 62, and heating pipes 63. The fan 61 is fixed to the outside of the drying chamber 21 and located above the heating chamber 62. The heating chamber 62 is fixed to the outside of the drying chamber 21. The air outlet of the fan 61 is connected to the heating chamber 62. The heating pipes 63 are located inside the heating chamber 62. The side wall of the drying chamber 21 has multiple ventilation holes 212. The heating chamber 62 is connected to the drying chamber 21 through the ventilation holes 212. The heating device 6 is located on opposite sides of the drying chamber 21. Specifically, the heating device 6 is located on both sides of the feed inlet 211. There can be multiple sets of heating pipes 63 on each side wall to improve the uniformity of heating of the product inside the drying chamber 21.

[0034] When the heating device 6 is working, the heating tube 63 heats the product, and the fan 61 blows hot air downwards from the top of the heating chamber 62, ensuring that the hot air is evenly distributed throughout the heating chamber 62 and flows evenly into the drying chamber 21. Through the convection of hot air on both sides, the heat is evenly distributed within the drying chamber 21, allowing the hot air to dry the product evenly. Simultaneously, the downward blowing by the fan 61 reduces upward heat loss, thus improving heat utilization efficiency.

[0035] The cooling device 7 includes axial flow fans 71, which are located on opposite sides of the cooling chamber 22. The drying chamber 21 and the cooling chamber 22 are separated by a partition 40. There are multiple axial flow fans 71 on each side. During cooling, the axial flow fans 71 on both sides are turned on, which can accelerate the convection between the cooling chamber 22 and the outside air, so that the product in the cooling chamber 22 can be quickly cooled to room temperature.

[0036] like Figure 1 , Figure 5 and Figure 9 As shown, the three-dimensional oven also includes a support frame 8 and limiting rods 9. The support frame 8 is located at the bottom of the drying chamber 21. Limiting rods 9 are provided inside both the drying chamber 21 and the cooling chamber 22. The limiting rods 9 are arranged along the height direction of the drying chamber 21 and the cooling chamber 22. There are multiple limiting rods 9, and each limiting rod 9 has a flow strip 10 on its inner side (i.e., the side closest to the material tray). The support frame 8 is equipped with a backstop assembly 20. The limiting rods 9 are located around the material tray inside the drying chamber 21, which can limit the movement of the material tray around its perimeter, ensuring the stability of the material tray during stacking. The flow strips 10 allow the material tray to contact the rollers on the flow strips 10, thereby reducing the friction force experienced by the material tray when moving upwards, facilitating the smooth upward stacking of the material tray.

[0037] The support frame 8 is fixed on both sides of the feed inlet 211. Rollers 81 are installed on the support frame 8. The material tray input from the feed inlet 211 is placed on the rollers 81, which makes it convenient for the feeding mechanism 3 to push the material tray into the drying box 21.

[0038] The anti-reverse assembly 20 includes a fixing member 201, a swing member 202, a spring 203 (obscured by the swing member 202 in the figure and not shown), and a rotating shaft 204. The fixing member 201 is fixed to the support frame 8 by screws. An opening slot is provided on the front side of the fixing member 201. The swing member 202 is located in the opening slot. The rotating shaft 204 is sleeved on the bottom of the swing member 202. Both ends of the rotating shaft 204 pass through the swing member 202 and are sleeved on the side walls of the opening slot. The spring 203 is located above the rotating shaft 204. One end of the spring 203 is connected to and abuts against the swing member 202, and the other end abuts against the bottom of the opening slot. The length of the top of the swing member 202 is greater than the length of its bottom. When the spring 203 is in its natural state, the inner side of the bottom of the swing member 202 abuts against the bottom of the opening groove, limiting the swing member 202. At this time, when the top surface of the swing member 202 is in a horizontal state, the top of the swing member 202 extends beyond the fixing member 201, and the swing member 202 is located above the roller 81.

[0039] Specifically, when the tray is pushed into the rollers 81 on the support frame 8 inside the drying chamber 21, the feeding mechanism 3 pushes the tray upward. At this time, the edge of the tray acts on the swing member 202, causing the swing member 202 to rotate and compress the spring 203 inward, so that the tray can move upward normally. When the tray moves above the swing member 202, the spring 203 pushes the top of the swing member 202 outward. At this time, the feeding mechanism 3 places the tray above the swing member 202, and the swing member 202 supports the entire stack of trays, so that the feed inlet 211 can continue to push the tray in and place it on the rollers 81 below.

[0040] like Figure 4 , Figures 6-9 As shown, the feeding mechanism 3 includes a feeding rack 31, a first lifting device 32, a front-to-back moving device 33, and a first lifting device 34. The feeding rack 31 is located on one side of the frame 1. The first lifting device 32 and the front-to-back moving device 33 are both mounted on the feeding rack 31. The first lifting device 34 is mounted on the frame 1 and located below the drying chamber 21. The front-to-back moving device 33 is connected to the first lifting device 32. One end of the front-to-back moving device 33 corresponds to the feed inlet 211 of the drying chamber 21. The top end of the first lifting device 34 can penetrate the bottom of the drying chamber 21 and extend into the drying chamber 21. The top end of the first lifting device 34 corresponds to the anti-reverse component 20. That is, through the first lifting device 34, the material tray can be pushed upward to the top of the swing component 202, so that the entire stack of material trays is placed on the swing component 202 for support.

[0041] The first lifting device 32 includes a lifting motor 321, a lifting synchronous belt 322, and a lifting frame 323. The lifting motor 321 is fixed on the loading frame 31. The lifting synchronous belt 322 is connected to the output shaft of the lifting motor 321. One end of the lifting frame 323 is clamped and fixed on the lifting synchronous belt 322 by screws. The front and rear moving device 3 is provided on the lifting frame 323.

[0042] The first lifting device 32 also includes two lifting synchronous pulleys 324, arranged vertically. One lifting synchronous pulley 324 is mounted on the output shaft of the lifting motor 321, and the other lifting synchronous pulley 324 is mounted on the loading frame 31. A lifting synchronous belt 322 is mounted on the two lifting synchronous pulleys 324. When the lifting motor 321 operates, it drives one of the lifting synchronous pulleys 324 to rotate, thereby driving the lifting synchronous belt 322 to transport materials, which in turn drives the lifting frame 323 to rise and fall under the influence of the lifting synchronous belt 322. By controlling the rotation direction of the lifting motor 321, the rising and falling of the lifting frame 323 can be controlled.

[0043] In actual use, to facilitate the smooth lifting and lowering of the lifting frame 323, two guide rails 325 are fixed to the loading rack 31 with screws. The two guide rails 325 are located on both sides of the lifting synchronous belt 322, and are vertically arranged. A slider is fixed on the lifting frame 323, and the slider cooperates with the guide rail 325. Thus, through the cooperation between the slider and the guide rail 325, the lifting frame 323 can smoothly lift and lower along the corresponding side of the lifting synchronous belt 322.

[0044] The first lifting device 34 includes a drive motor 341, a lifting plate 342, a lifting rod 343, and a support rod 344. The drive motor 341 is mounted on the frame 1. The lifting plate 342 is connected to the output shaft of the drive motor 341. The lifting rods 343 are mounted on the lifting plate 342, and there are multiple lifting rods 343. The lifting rods 343 penetrate the bottom of the drying oven 21 and extend into the drying oven 21. The two ends of the support rod 344 are fixed to the top of the lifting rods 343. The drive motor 341 is a linear motor with a screw shaft. The lifting plate 342 is threaded to the output shaft of the linear motor. The lifting rods 343 can penetrate the bottom of the oven and extend upward. Through the cooperation between the lifting rods 343 and the oven, the lifting rods can be limited, preventing the lifting rods 343 and the lifting plate 342 from rotating. Therefore, when the drive motor 341 is working, the lifting plate 342 can be raised and lowered relative to the output shaft of the drive motor 341.

[0045] The forward and backward moving device 33 includes a forward and backward moving motor 331, a forward and backward moving synchronous belt 332, and a forward and backward moving synchronous pulley 333. The forward and backward moving motor 331 is mounted on the lifting frame 323. There are two forward and backward moving synchronous pulleys 333, one of which is mounted on the output shaft of the forward and backward moving motor 331, and the other is mounted on the lifting frame 323. The forward and backward moving synchronous belt 332 is mounted on the two forward and backward moving synchronous pulleys 333. The forward and backward moving synchronous belt 332 corresponds to the feed inlet 211, that is, the material tray is conveyed forward to the top of the first lifting device 34 through the forward and backward moving synchronous belt 332.

[0046] There are two sets of front and rear moving synchronous belts 332, which are arranged in parallel. Two more front and rear moving synchronous pulleys 333 are added accordingly. The front and rear moving synchronous pulleys of the two sets of front and rear moving synchronous belts 332 are connected by a rotating shaft to facilitate the synchronous conveying of the two sets of front and rear moving synchronous belts 332.

[0047] In use, the tray is placed on the forward and backward moving synchronous belt 332. When the forward and backward moving device 33 moves upward under the drive of the first lifting device 32, the tray moves upward accordingly. When the tray is in place, the product is placed on the tray, and the forward and backward moving motor 331 drives the forward and backward moving synchronous belt 332 to convey it forward, thereby conveying the tray forward and into the drying chamber 21.

[0048] The feeding mechanism 3 also includes a mounting frame 35, which is fixed to the lifting frame 323. The forward and backward moving device 33 is mounted on the lifting frame 323 via the mounting frame 35. The mounting frame 35 is fixed to the lifting frame 323 with screws, and the mounting frame 35 facilitates the installation of various structures of the forward and backward moving device 33.

[0049] The feeding mechanism 3 also includes a pushing device 36, which includes a push rod 361 and a push rod cylinder 362. The push rod cylinder 362 is mounted on the lifting frame 323, and the push rod 361 is connected to the push rod cylinder 362. The push rod 361 corresponds to the first lifting device 34. Specifically, the piston rod of the push rod cylinder 362 is fixed on the mounting frame 35, and the push rod 361 is fixed to the cylinder body of the push rod cylinder 362. Therefore, by moving the cylinder body of the push rod cylinder 362 relative to the piston rod, the push rod 361 can be moved.

[0050] When the trays are conveyed forward into the drying chamber 21 by the synchronous belt 32, the pusher cylinder 362 pushes the pusher 361 forward. The pusher 361 acts on the trays, pushing them further forward onto the rollers 81 until they are in place, ensuring that each tray is pushed to the same position for easy stacking. Once the trays are in place in the drying chamber 21, the pusher cylinder 362 pulls back, causing the pusher 361 to pull back as well. The lifting motor 321 rotates in the opposite direction, driving the lifting frame 323 downward to facilitate the conveying of the next tray.

[0051] Once the tray is positioned above roller 81, drive motor 341 moves lifting plate 342 upward, pushing top rod 343 and support rod 344 upward, causing support rod 344 to act on the bottom of the tray. As support rod 344 continues to rise, it pushes the tray on roller 81 upward, causing it to act on swing member 202, allowing it to move upward and stack with the tray above it. When the bottom tray moves above swing member 202, spring 203 pushes the top of swing member 202 out. Subsequently, drive motor 341 rotates in the opposite direction, moving support rod 344 downward, causing the entire stack of trays to move downward and finally rest on top of swing member 202. Drive motor 341 then moves support rod 344 downward to reset. At this point, forward and backward moving device 33 can continue to move the next tray into drying chamber 21, repeating the action to stack the trays one by one from bottom to top. While the trays are stacked upward, heating device 6 continuously dries the products on the trays.

[0052] When an additional tray is added below the stack of trays, the stack of trays will move upwards a certain distance. When the trays are moved to the top, the products in the trays are dried and then moved into the cooling box 22 by the transfer mechanism 5.

[0053] like Figure 1 and Figure 14 As shown, the material transfer mechanism 5 includes a material transfer rack 51, a moving device 52, a third lifting device 53, and a clamping device 54. The moving device 52 is mounted on the material transfer rack 51, the third lifting device 53 is mounted on the moving device 52, and the clamping device 54 is connected to the third lifting device 53. The clamping device 54 is located on both sides of the moving device 52. The material transfer rack 51 is fixed to the top of the box 2 and extends from the top of the drying box 21 to the top of the cooling box 22.

[0054] When in use, the material transfer mechanism 5 can move the third lifting device 53 and the clamping device 54 through the moving device 52; the third lifting device 53 drives the clamping device 54 to lift and lower, the clamping device 54 can clamp the material tray, and then under the action of the moving device 52, the material tray is moved from the drying box 21 to the cooling box 22.

[0055] The moving device 52 includes a motor 521 and a linear slide module 522. The linear slide module 522 is connected to the output shaft of the motor 521. The linear slide module 522 includes a linear slide rail 5221 and a first slider 5222. The linear slide rail 5221 is mounted on the transfer rack 51, and the first slider 5222 is mounted on the linear slide rail 5221. A third lifting device 53 is mounted on the first slider 5222. The linear slide rail 5221 extends from the top of the drying chamber 21 to the top of the cooling chamber 22. The linear slide module 522 is existing technology, therefore its specific working principle will not be described in detail. When the moving device 52 is working, starting the motor 521 can drive the first slider 5222 to slide on the linear slide rail 5221, thereby moving the third lifting device 53. By controlling the forward and reverse rotation of the motor 521, the direction of movement of the first slider 5222 can be controlled, facilitating the movement of the clamping device 54 above the drying chamber 21 and the cooling chamber 22.

[0056] The material transfer mechanism 5 also includes a mounting plate 55, which is fixed above the first slider 5222 by screws, and the third lifting device 53 is located on the mounting plate 55.

[0057] The third lifting device 53 includes a lifting cylinder 531, which is fixed on the mounting plate 55. The piston rod of the lifting cylinder 531 extends downward after passing through the mounting plate 55. The lifting cylinder 531 is vertically arranged. The clamping device 54 is connected to the piston rod of the lifting cylinder 531. There are two lifting cylinders 531, located on both sides of the linear slide rail 5221. There are also two clamping devices 54, which are correspondingly connected to the two lifting cylinders 531. By providing two lifting cylinders 531 and two clamping devices 54, the clamping device 54 can clamp the material tray at multiple points, thereby improving the stability of the material tray during movement, avoiding movement and collision of precision components on the material tray, and thus helping to ensure product quality.

[0058] The clamping device 54 includes a finger cylinder 541 and a clamping plate 542. The finger cylinder 541 is connected to the piston rod of the lifting cylinder 531, and the clamping plate 542 is connected to the piston rods on both sides of the finger cylinder 541. In actual use, a sliding groove 214 for moving the clamping plate 542 is provided on the top of the drying chamber 21. The tray can move along the sliding groove 214 and move out of the drying chamber 21 through the connecting hole 213 and into the cooling chamber 22 without opening the drying chamber 21, which greatly reduces heat loss and achieves energy saving. The clamping plates 542 on both sides of the finger cylinder 541 can be clamped and opened by the finger cylinder 541, which facilitates the clamping and releasing of the tray.

[0059] The bottom end of the clamping plate 542 is provided with a hook 56 and an adjusting screw 57. The hook 56 is L-shaped, and a vertical groove 561 is provided on the vertical side of the hook 56. One end of the adjusting screw 57 is located on the outside of the hook 56, and the other end passes through the vertical groove 561 and is fixed to the clamping plate 542. A threaded hole is provided on the outside of the clamping plate 542 to facilitate the engagement with the adjusting screw 57.

[0060] In use, once the extension and retraction stroke of the lifting cylinder 531 is determined, the hook 56 can be adjusted to accommodate material trays of different thicknesses, allowing the horizontal edge at the bottom of the hook 56 to move up and down accordingly. Specifically, when the height of the hook 56 needs adjustment, loosen the adjusting screw 57 to allow the hook 56 to move along the direction of the vertical groove 561; after the height of the hook 56 is adjusted to the correct position, tighten the adjusting screw 57 to fix the hook 56 at the corresponding height position, suitable for clamping material trays of different thicknesses.

[0061] As the product inside the drying chamber 21 gradually moves upward with the tray and reaches the top, drying is complete. At this point, the piston rod of the lifting cylinder 531 extends downward, pushing the finger cylinder 541 downward. The finger cylinder 541 drives the clamping plate 542 to open outward. After the clamping plate 542 and the hook 56 move into position, the finger cylinder 541 drives the clamping plate 542 to clamp the tray at the top of the drying chamber 21. Then, the piston rod of the lifting cylinder 531 pulls upward, moving the tray upward. Then, the moving device 52 moves the mounting plate 55 along the linear slide rail 5221, thereby moving the tray out of the connecting hole 213 and into the cooling chamber 22. After the piston rod of the lifting cylinder 531 moves downward into position, the finger cylinder 541 releases the clamping plate 542, placing the tray at the top of the stack of trays in the cooling chamber 22, completing the movement of the tray from the drying chamber 21 to the cooling chamber 22.

[0062] After the tray moves into the cooling box 22, it gradually moves downward from top to bottom under the action of the feeding mechanism 4. During the downward movement, the products on the tray gradually cool to room temperature under the action of the cooling device 7, thus achieving a cooling effect. This eliminates the need to extend the entire channel, greatly shortening it compared to existing cooling channels. At the same time, it can cool the entire stack of products, greatly improving cooling efficiency.

[0063] like Figure 4 ,like Figures 7-13As shown, the unloading mechanism 4 includes an unloading frame 41, a stop device 42, a second lifting device 43, a second lifting device 44, a first front-rear conveying device 45, and a second front-rear conveying device 46. The unloading frame 41 is located on the other side of the frame 1. The second lifting device 44 and the first front-rear conveying device 45 are mounted on the unloading frame 41. The second front-rear conveying device 46 is located on one side of the first front-rear conveying device 45 and is located inside the cooling box 22. The second lifting device 43 is located below the cooling box 22, with its top end penetrating through the bottom of the cooling box 22 and extending into it. The stop device 42 is located on both sides of the second front-rear conveying device 46. Both the stop device 42 and the second front-rear conveying device 46 are located inside the cooling box 22. The first front-rear conveying device 45 corresponds to the discharge port 221 of the cooling box 22. The second lifting device 44 has the same structure and working principle as the first lifting device 32.

[0064] In actual use, the structures of the first front and rear conveying device 45 and the second front and rear conveying device 46 are the same as the structure of the front and rear moving device 33. That is, the front and rear moving motor drives the front and rear moving synchronous belt 332 for conveying, thereby realizing the conveying of the material tray on the corresponding front and rear moving synchronous belt 332.

[0065] The structure of the second lifting device 43 is the same as that of the first lifting device 34. The difference is that the top of the top rod 343 of the second lifting device 43 can directly act on the edge of the material tray without connecting the support rod 344. The stop device 42 includes a cylinder 421 and a baffle 422. The cylinder 421 is located in the cooling box 22. The baffle 422 is connected to the cylinder 421 and is located above the second front and rear conveying device 46. The top rod 343 of the second lifting device 43 is located between the baffles 422 on both sides. Specifically, the piston rod of cylinder 421 is fixed above the bottom of cooling box 22, and baffle 422 is connected to the cylinder body of cylinder 421. When the bottom tray of cooling box 22 moves below baffle 422, the cylinder body of cylinder 421 moves relative to the piston rod, causing baffle 422 to move to one side of the second front and rear conveying device 46. At this time, the baffles 422 on both sides can prevent the other trays except the bottom tray from blocking the way and prevent the other trays from moving down, thus ensuring that only one tray is placed on the second front and rear conveying device 46 at a time.

[0066] In operation, cylinder 421 drives baffle 422 to extend, supporting the stack of trays within the cooling box 22. When the bottom tray in the cooling box 22 needs to be unloaded, the drive motor 341 in the second lifting device 43 starts, pushing the connected lifting plate and push rod upwards. The push rod 343 of the second lifting device 43 acts upwards on the bottom tray in the cooling box 22, supporting the stack of trays. At this time, cylinder 421 drives baffle 422 to move to both sides, releasing the support and obstruction of the trays. Subsequently, the drive motor 341 in the second lifting device 43 reverses, causing the corresponding push rod 343 to support the trays downwards. When the bottom tray moves below baffle 422, baffle 422 is extended by cylinder 421, preventing the remaining trays (except the bottom tray) from continuing to move downwards.

[0067] When the tray is placed downwards onto the synchronous belt 332 of the second front-rear conveyor 46 under the action of the second lifting device 43, the tray moves into position. Then, the second front-rear conveyor 46 starts working, causing the tray to be conveyed out from the outlet and onto the first front-rear conveyor 45, thus unloading the tray into the oven. After the tray is moved to the first front-rear conveyor 45, external equipment can remove the baked product from the tray. Subsequently, the lifting motor in the second lifting device 44 starts working, driving the lifting frame 43 in the second lifting device 44 downwards, thereby driving the entire first front-rear conveyor 45 downwards, and the tray on the first front-rear conveyor 45 moves downwards synchronously.

[0068] like Figure 4 , Figure 7 , Figure 11 and Figure 15 As shown, the three-dimensional oven of this utility model also includes a tray circulation mechanism 30. The tray circulation mechanism 30 includes a circulation frame 301, a first motor 302, and a tray conveyor belt 303. The circulation frame 301 is fixed on the frame 1 and located below the housing 2. The first motor 302 is fixed on the frame 1. The tray conveyor belt 303 is disposed on the circulation frame 301 and connected to the output shaft of the first motor 302. One end of the tray conveyor belt 303 corresponds to the first front and rear conveying device 45, and the other end corresponds to the front and rear moving device 33. The circulation frame 301 is located below the first lifting device 34 and the second lifting device 43. Therefore, the first motor 302 can drive the tray conveyor belt 303 to transport materials, thereby facilitating the transport of the tray on the tray conveyor belt 303.

[0069] When the lowest tray in the cooling box 22 is conveyed onto the first front-rear conveyor 45, the product is removed from the tray. Then, under the action of the second lifting device 44, the first front-rear conveyor 45 moves downwards. When the first front-rear conveyor 45 descends to the height of the tray conveyor belt 303, it conveys the tray onto the conveyor belt 303. The tray is then conveyed on the conveyor belt 303 and transported to the front-rear moving device 33. As the tray moves towards the front-rear moving device 33 under the action of the conveyor belt 303, the front-rear moving device 33 moves downwards under the action of the first lifting device 32, causing it to descend to the height of the tray conveyor belt 303. Thus, the tray is conveyed to the synchronous belt 332 of the forward and backward moving device 33 by the tray conveyor belt 303; then the first lifting device 32 drives the forward and backward moving device 33 to move upward, so that the product to be baked can be put into the tray; then, the tray containing the product in the forward and backward moving device 33 enters the drying box 21 through the feed inlet 211 under the action of the forward and backward moving device 33, completing the whole cycle.

[0070] Therefore, in use, the three-dimensional oven of this invention, through the coordinated action of its various structures, allows the trays to gradually stack upwards within the drying chamber 21. As they move upwards, continuous heating of the products within the multiple trays is achieved, enabling continuous product intake and output, thus improving drying efficiency and significantly increasing heat energy utilization. When baking multiple products, there is no need to increase the overall length of the oven, thereby greatly reducing the space occupied by the oven and lowering the requirements for factory space. Simultaneously, the cooling chamber 22 also cools the products within the stacked trays, improving cooling efficiency and reducing the space occupied by cooling, which contributes to a reduction in the overall oven size. In actual use, the height and number of trays stacked in the drying chamber 21 and cooling chamber 22 can be increased according to actual usage requirements, and the overall height of the chamber 2 can be adjusted accordingly to meet different usage needs.

[0071] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
