One end of the front-and-back moving device corresponds to the feeding port of the drying box. The top of the first lifting device can penetrate the bottom of the drying box and then extend into the drying box. The top of the first lifting device corresponds to the stop assembly. Thus, by providing the first lifting device, the material tray can be transported from the bottom to the top, which is convenient for placing the product on the material tray; then, by the front-and-back moving device, the material tray after the product is placed is transported to the oven; then, by the first lifting device, the material tray can be pushed upward, which is convenient for placing the material tray on the stop assembly in the drying box, thereby realizing automatic feeding of the material tray, and there is no need to manually put the material tray into the drying box, which saves labor and saves the feeding time of the material tray, which is conducive to improving production efficiency.

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] Reference Figure 1 to Figure 4 The three-dimensional oven comprises a frame 1, a box body 2, a feeding mechanism 3, a feeding mechanism 4, a material transfer mechanism 5, a heating device 6 and a cooling device 7. The box body 2 is arranged on the frame 1, and the box body 2 comprises a drying box 21 and a cooling box 22. The heating device 6 is arranged on the drying box 21, and the cooling device 7 is arranged on the cooling box 22. A feeding port 211 is arranged on one side of the drying box 21, and the cooling box 22 is located on the other side of the drying box 21. A material discharge port 221 is arranged on one side of the cooling box 22. The feeding mechanism 3 is arranged corresponding to the drying box 21, and the feeding mechanism 4 is corresponding to the cooling box 22. The material transfer mechanism 5 is arranged on the top of the box body 2, and the material transfer mechanism 5 corresponds to the top of the drying box 21 and the top of the cooling box 22.

[0032] When the three-dimensional oven of the present invention is used, in order to facilitate the drying of products in the drying box 21 and prevent the products from being scratched, the products are placed in a tray, and then placed in the drying box 22 together with the tray. Products such as glass parts, membrane switches, and liquid crystal display screens are placed in the tray at the feeding mechanism 3, and the trays are transported into the drying box 21 through the feeding port 211 by the feeding mechanism 3, and gradually stacked upward from bottom to top, so that the trays can be continuously input at the feeding port 211, and the products in the stacked trays can be heated and dried at the same time without extending the entire heating channel, which greatly reduces the volume of the drying box and improves the drying efficiency. When the tray gradually rises to the top of the drying box 21, the product is dried. At this time, the top tray is clamped and moved to the cooling box 22 by the material moving mechanism 5. In order to facilitate the movement of the material tray from the drying box 21 to the cooling box 22, a connecting hole 213 is provided at the top of the drying box 21 near the cooling box 22, so that the material tray can be moved into the cooling box 22 through the connecting hole 213 under the clamping of the material moving mechanism 5. The material tray moves from top to bottom in the cooling box 22, and when it moves downward to the discharge port 221, the product in the material tray cools to room temperature. When the material tray moves down to the discharge port 221, the material tray is removed from the cooling box 22 by the unloading mechanism 4, so that the baked product on the material tray can be taken out, and the baking of the product is completed.

[0033] The heating device 6 includes a fan 61, a heating box 62 and a heating pipe 63. The fan 61 is fixed on the outside of the drying box 21 and is located above the heating box 62. The heating box 62 is fixed on the outside of the drying box 21. The air outlet of the fan 61 is connected to the heating box 62. The heating pipe 63 is arranged in the heating box 62. The side wall of the drying box 21 is provided with a plurality of ventilation holes 212. The heating box 62 is connected to the drying box 21 through the ventilation holes 212. The heating device 6 is located on opposite sides of the drying box 21. The heating device 6 is located on both sides of the feed port 211. The heating pipe 63 on each side wall can be multiple groups to improve the heating uniformity of the product in the drying box 21.

[0034] When the heating device 6 is working, the heating tube 63 heats, and the fan 61 blows downward from the top of the heating box 62, so that the hot air can be evenly distributed in the entire heating box 62 and evenly flows into the entire drying box 21; through the convection of hot air on both sides, the heat in the drying box 21 is evenly distributed, so that the hot air can evenly dry the product. At the same time, the fan 61 blows downward, which can reduce the upward loss of heat and help improve the heat utilization rate.

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

[0036] like Figure 1 , Figure 5 and Fig. 9 As shown, the three-dimensional oven also includes a support frame 8 and a limit rod 9. The support frame 8 is located at the bottom of the drying box 21. The drying box 21 and the cooling box 22 are both provided with limit rods 9. The limit rods 9 are arranged along the height direction of the drying box 21 and the cooling box 22. There are multiple limit rods 9. The inner side of each limit rod 9 (i.e., the side close to the material tray) is provided with a smooth bar 10. The support frame 8 is provided with a stop assembly 20. The limit rod 9 is located around the material tray in the drying box 21, and can limit the four sides of the material tray to ensure the stability of the material tray when stacking. By providing the smooth bar 10, the material tray is in contact with the roller on the smooth bar 10, thereby reducing the friction force of the material tray when moving upward, which is conducive to the stable upward stacking of the material tray.

[0037] The support frame 8 is fixed on both sides of the feed port 211 , and rollers 81 are installed on the support frame 8 . The material tray input from the feed port 211 is placed on the rollers 81 , which facilitates the loading mechanism 3 to push the material tray into the drying box 21 .

[0038] The backstop assembly 20 includes a fixing member 201, a swinging member 202, a spring 203 (hidden by the swinging 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 open slot is provided on the front side of the fixing member 201, the swinging member 202 is located in the open slot, the rotating shaft 204 is sleeved on the bottom of the swinging member 202, and both ends of the rotating shaft 204 penetrate the swinging member 202 and are sleeved on the side walls of the open slot; the spring 203 is located above the rotating shaft 204, one end of the spring 203 is connected and abutted with the swinging member 202, and the other end abuts with the bottom of the open slot; the length of the top of the swinging member 202 is greater than the length of its bottom. When the spring 203 is in a natural state, the inner side of the bottom of the swing member 202 abuts against the bottom of the open groove to limit 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 exceeds the fixed member 201, and the swing member 202 is located above the roller 81.

[0039] Specifically, after the material tray is pushed into the roller 81 on the support frame 8 in the drying box 21, the material tray can be pushed upward under the action of the feeding mechanism 3. At this time, the frame of the material tray acts on the swinging member 202, causing the swinging member 202 to rotate and compress the spring 203 inward, so that the material tray can move upward normally; when the material tray moves to the top of the swinging member 202, the spring 203 pushes the top of the swinging member 202 outward. At this time, the feeding mechanism 3 places the material tray above the swinging member 202, and supports the entire stack of material trays through the swinging member 202, thereby facilitating the material tray to continue to be pushed in at the feed port 211 and placed on the roller 81 below.

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

[0041] Among them, 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, and one end of the lifting frame 323 is fixed on the lifting synchronous belt 322 by screw locking and clamping, and the front and rear moving device 3 is arranged on the lifting frame 323.

[0042] The first lifting device 32 also includes lifting synchronous wheels 324, which are two and are distributed up and down. One of the lifting synchronous wheels 324 is sleeved on the output shaft of the lifting motor 321, and the other lifting synchronous wheel 324 is arranged on the loading rack 31. The lifting synchronous belt 322 is sleeved on the two lifting synchronous wheels 324. When the lifting motor 321 is working, it drives one of the lifting synchronous wheels 324 to rotate, thereby driving the lifting synchronous belt 322 to convey, thereby driving the lifting rack 323 to lift and lower under the drive of the lifting synchronous belt 322. By controlling the rotation direction of the lifting motor 321, the lifting and lowering of the lifting rack 323 can be controlled.

[0043] In actual use, in order to facilitate the smooth lifting of the lifting frame 323, two guide rails 325 are fixed on the loading frame 31 by screws. The two guide rails 325 are respectively located on both sides of the lifting synchronous belt 322. The guide rails 325 are vertically arranged, and a slider is fixed on the lifting frame 323, and the slider cooperates with the guide rail 325. Therefore, through the cooperation of the slider and the guide rail 325, the lifting frame 323 is convenient for the corresponding side of the lifting synchronous belt 322 to be smoothly lifted and lowered.

[0044] The first lifting device 34 includes a driving motor 341, a lifting plate 342, a push rod 343 and a support rod 344. The driving motor 341 is arranged on the frame 1. The lifting plate 342 is connected to the output shaft of the driving motor 341. The push rod 343 is arranged on the lifting plate 342. There are multiple push rods 343. The push rods 343 penetrate the bottom end of the drying box 21 and extend into the drying box 21. The two ends of the support rod 344 are fixed to the top of the push rod 343. Among them, the driving motor 341 is a linear motor, and its output shaft is a screw. The lifting plate 342 and the output shaft of the linear motor are threadedly matched. The push rod 343 can penetrate the bottom of the oven and extend upward; through the cooperation between the push rod 343 and the oven, the push rod can be limited, and the push rod 343 and the lifting plate 342 can be prevented from rotating. Therefore, when the driving motor 341 is working, the lifting plate 342 can be lifted and lowered relative to the output shaft of the driving 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 wheel 333. The forward and backward moving motor 331 is arranged on the lifting frame 323. There are two forward and backward moving synchronous wheels 333, one of which is sleeved on the output shaft of the forward and backward moving motor 331, and the other is sleeved on the lifting frame 323. The forward and backward moving synchronous belt 332 is sleeved on the two forward and backward moving synchronous wheels 333. The forward and backward moving synchronous belt 332 corresponds to the feed port 211, that is, the material tray is transported forward to the top of the first jacking device 34 through the forward and backward moving synchronous belt 332.

[0046] Among them, there are two groups of forward and backward moving synchronous belts 332, and they are arranged in parallel. Two forward and backward moving synchronous wheels 333 are added accordingly. The corresponding forward and backward moving synchronous wheels of the two groups of forward and backward moving synchronous belts 332 are connected by a rotating shaft to facilitate the synchronous transportation of the two groups of forward and backward moving synchronous belts 332.

[0047] When in use, the tray is placed on the front-rear moving synchronous belt 332, and when the front-rear moving device 33 moves upward driven by the first lifting device 32, the tray moves upward along with it. When the tray rises to the right position, the product is placed on the tray, and the front-rear moving motor 331 drives the front-rear moving synchronous belt 332 to convey forward, thereby driving the tray to convey forward and convey it into the drying box 21.

[0048] The feeding mechanism 3 further includes a mounting frame 35, which is fixed on the lifting frame 323, and the front and rear moving device 33 is arranged on the lifting frame 323 through the mounting frame 35. Among them, the mounting frame 35 is fixed on the lifting frame 323 by screws, and the mounting frame 35 facilitates the installation of various structures of the front and rear moving device 33.

[0049] The feeding mechanism 3 further includes a pushing device 36, which includes a push rod 361 and a push rod cylinder 362. The push rod cylinder 362 is arranged 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, the push rod 361 can be driven to move by the movement of the cylinder body of the push rod cylinder 362 relative to the piston rod.

[0050] When the tray is transported forward into the drying box 21 driven by the forward and backward moving synchronous belt 32, the push rod cylinder 362 pushes the push rod 361 forward, and the push rod 361 acts on the tray forward, so that the tray continues to be pushed forward on the roller 81 to the right position, thereby ensuring that each tray can be pushed to the same position, which is convenient for stacking the trays. When the tray is transported forward into the drying box 21, the push rod cylinder 362 pulls back, so that the push rod 361 pulls back, and the lifting motor 321 rotates in the opposite direction, driving the lifting frame 323 to move downward, which is convenient for the transportation of the next tray.

[0051] After the tray is located above the roller 81, the driving motor 341 drives the lifting plate 342 to move upward, pushing the push rod 343 and the support rod 344 to move upward, so that the support rod 344 acts on the bottom of the tray. As the support rod 344 continues to rise, the support rod 344 pushes the tray on the roller 81 upward, and the tray acts on the swing member 202, so that the tray can move upward and stack with the tray above; when the bottom tray moves above the swing member 202, the spring 203 pushes out the top of the swing member 202; then, the driving motor 341 rotates in the opposite direction, driving the support rod 344 to move downward, so that the whole stack of trays moves downward and is finally supported above the swing member 202; the driving motor 341 drives the support rod 344 to move downward and reset. At this time, the front-rear moving device 33 can continue to drive the next tray into the drying box 21, repeating the action to achieve stacking of the trays from bottom to top one by one. When the trays are stacked upward, the heating device 6 continues to dry the products on the trays.

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

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

[0054] When the material moving mechanism 5 is in use, the moving device 52 can drive the third lifting device 53 and the clamping device 54 to move; the third lifting device 53 drives the clamping device 54 to lift and lower, and the clamping device 54 can clamp the material tray, and then under the movement 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 arranged on the material transfer rack 51, the first slider 5222 is arranged on the linear slide rail 5221, and the third lifting device 53 is arranged on the first slider 5222; the linear slide rail 5221 extends from the top of the drying box 21 to the top of the cooling box 22. Among them, the linear slide module 522 is a prior art, so its specific working principle is not repeated. 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 driving the third lifting device 53 to move; by controlling the forward and reverse rotation of the motor 521, the moving direction of the first slider 5222 can be controlled, so that the clamping device 54 can move above the drying box 21 and the cooling box 22.

[0056] The material moving mechanism 5 further includes a mounting plate 55 , which is fixed above the first sliding block 5222 by screws, and the third lifting device 53 is disposed 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 penetrating 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, which are respectively located on both sides of the linear slide rail 5221. There are 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 when moving, avoiding the movement and collision of precision components on the material tray, and thus facilitating the quality of the product.

[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 slide groove 214 for moving the clamping plate 542 is provided on the top of the drying box 21. The material tray can move along the slide groove 214 and move out of the drying box 21 through the connecting hole 213 and enter the cooling box 22 without opening the drying box 21, which greatly reduces heat loss and achieves energy saving. Through the finger cylinder 541, the clamping plates 542 on both sides of the finger cylinder 541 can be clamped and opened, thereby facilitating the clamping and loosening of the material 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 outside 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, and the threaded hole facilitates the cooperation with the adjusting screw 57.

[0060] When in use, after the telescopic stroke of the lifting cylinder 531 is determined, in order to adapt to the clamping of trays of different thicknesses, the hook 56 can be adjusted so that the horizontal side of the bottom of the hook 56 moves up and down accordingly. Specifically, when the height position of the hook 56 needs to be adjusted, the adjusting screw 57 is loosened so that the hook 56 can move along the direction of the vertical slot 561; when the height of the hook 56 is adjusted to the right position, the adjusting screw 57 is tightened again so that the hook 56 is fixed at the corresponding height position, which is suitable for clamping trays of different thicknesses.

[0061] When the product in the drying box 21 gradually moves up with the tray and moves to the top, the drying is completed. At this time, when the piston rod of the lifting cylinder 531 extends downward, it pushes the finger cylinder 541 to move downward, and the finger cylinder 541 drives the clamping plate 542 to open outward; when the clamping plate 542 and the hook 56 move down to the right position, the finger cylinder 541 drives the clamping plate 542 to clamp the top tray in the drying box 21; then the piston rod of the lifting cylinder 531 is pulled upward to drive the tray to move upward; then the mounting plate 55 is moved along the linear slide rail 5221 through the moving device 52, so that the tray moves out of the connecting hole 213 and enters the cooling box 22. Then, after the piston rod of the lifting cylinder 531 moves downward to the right position, the finger cylinder 541 releases the clamping plate 542, so that the tray is placed at the top of the stacked trays in the cooling box 22, and the tray is moved from the drying box 21 to the cooling box 22.

[0062] After the material tray moves into the cooling box 22, the material tray gradually moves downward from top to bottom under the action of the unloading mechanism 4. During the gradual downward movement, under the action of the cooling device 7, the products on the material tray are gradually cooled to room temperature, thereby achieving a cooling effect. There is no need to extend the entire channel, which is greatly shortened compared to the existing cooling channel. At the same time, the entire stack of products can be cooled, greatly improving the cooling efficiency.

[0063] like Figure 4 ,like Figure 7 to Figure 13As shown, the unloading mechanism 4 includes an unloading frame 41, a stopper device 42, a second jacking device 43, a second lifting device 44, a first front-to-back conveying device 45, and a second front-to-back conveying device 46. The unloading frame 41 is located at the other side of the frame 1, the second lifting device 44 and the first front-to-back conveying device 45 are arranged on the unloading frame 41, the second front-to-back conveying device 46 is located at one side of the first front-to-back conveying device 45, the second front-to-back conveying device 46 is located in the cooling box 22, the second jacking device 43 is located below the cooling box 22, the top end of the second jacking device 43 penetrates through the bottom of the cooling box 22 and then extends into the cooling box 22, the stopper device 42 is located at both sides of the second front-to-back conveying device 46, the stopper device 42 and the second front-to-back conveying device 46 are both located in the cooling box 22, and the first front-to-back conveying device 45 corresponds to the discharge port 221 of the cooling box 22. The second lifting device 44 has the same structure as the first lifting device 32, and the working principle is also the same.

[0064] During actual use, the structure of the first front-and-rear conveying device 45 and the structure of 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 synchronous belt 332 is driven by the front-and-rear moving motor for conveying, thereby realizing the conveyance 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, except that the top end of the push rod 343 of the second lifting device 43 can directly act on the frame of the material tray without connecting the support rod 344, and the shifting device 42 includes a cylinder 421 and a baffle 422, the cylinder 421 is arranged 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, and the push rod 343 of the second lifting device 43 is located between the baffles 422 on both sides. Specifically, the piston rod of the cylinder 421 is fixed above the bottom of the cooling box 22, and the baffle 422 is connected to the cylinder body of the cylinder 421; when the material tray at the bottom of the cooling box 22 moves to the bottom of the baffle 422, the cylinder body of the cylinder 421 moves relative to the piston rod, driving the baffle 422 to move to one side of the second front-rear conveying device 46. At this time, the baffles 422 on both sides can prevent the remaining material trays except the bottom material tray from being blocked and preventing the remaining material trays from continuing to move downward, thereby ensuring that only one material tray is placed downward on the second front-rear conveying device 46 at a time.

[0066] When in use, the cylinder 421 drives the baffle 422 to be pushed out, and the baffle 422 can support the whole stack of trays in the cooling box 22. When the bottom tray in the cooling box 22 needs to be unloaded, the drive motor 341 in the second jacking device 43 is started, pushing the jacking plate and the push rod connected thereto to move upward, and the push rod 343 of the second jacking device 43 acts upward on the bottom tray of the cooling box 22 to support the whole stack of trays; at this time, the cylinder 421 drives the baffle 422 to move to both sides to release the support and isolation of the tray. Subsequently, the drive motor 341 in the second jacking device 43 is reversed, so that the corresponding push rod 343 supports the tray to move downward, and when the bottom tray moves down to the bottom of the baffle 422, the baffle 422 is pushed out by the action of the cylinder 421, and the baffle 422 prevents the remaining trays except the bottom tray from continuing to move downward.

[0067] When the tray is placed downward on the front-rear moving synchronous belt 332 of the second front-rear conveying device 46 under the action of the second lifting device 43, the tray moves down to its position; then, the second front-rear conveying device 46 starts to work, so that the tray is transported out from the discharge port under the action of the second front-rear conveying device 46 and transported to the first front-rear conveying device 45, so as to realize the unloading of the tray in the oven. After the tray is moved out to the first front-rear conveying device 45, the corresponding external equipment can take the baked product out of the tray. Then, the lifting motor in the second lifting device 44 starts to work, driving the lifting frame 43 in the second lifting device 44 to move downward, thereby driving the entire first front-rear conveying device 45 to move downward, and the tray on the first front-rear conveying device 45 moves downward synchronously.

[0068] like Figure 4 , Figure 7 , Fig.11 and Fig.15 As shown, the three-dimensional oven of the present invention further includes a tray circulation mechanism 30, which includes a circulation frame 301, a first motor 302 and a tray conveying belt 303. The circulation frame 301 is fixed on the frame 1 and is located below the box body 2. The first motor 302 is fixed on the frame 1. The tray conveying belt 303 is arranged on the circulation frame 301 and is connected to the output shaft of the first motor 302. One end of the tray conveying 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 tray conveying belt 303 can be driven to convey by the first motor 302, thereby facilitating the conveyance of the tray on the tray conveying belt 303.

[0069] When the tray at the bottom of the cooling box 22 is conveyed to the first front-rear conveying device 45, the product is taken out of the tray, and then, under the action of the second lifting device 44, the first front-rear conveying device 45 is driven to move downward, and when the first front-rear conveying device 45 is lowered to the height of the tray conveying belt 303, the first front-rear conveying device 45 conveys the tray to the tray conveying belt 303. Subsequently, the tray is conveyed on the tray conveying belt 303 and conveyed to the front-rear moving device 33. When the tray moves to the side of the front-rear moving device 33 under the action of the tray conveying belt 303, the front-rear moving device 33 moves downward under the drive of the first lifting device 32, and the front-rear moving device 33 is lowered to the height of the tray conveying belt 303. Thus, the tray is conveyed to the front-rear moving synchronous belt 332 of the front-rear moving device 33 by the tray conveying belt 303; then the first lifting device 32 drives the front-rear moving device 33 to move upward, so that the baked products can be placed in the tray; then, the tray with the products placed in the front-rear moving device 33 enters the drying box 21 through the feed port 211 under the action of the front-rear moving device 33, completing the whole cycle.

[0070] Therefore, when the three-dimensional oven of the present invention is in use, the various structures cooperate with each other, so that the material trays are gradually stacked upward in the drying box 21. When gradually moving upward, the continuous heating of the products in the multiple material trays is achieved, and the continuous entry and continuous output of the products are achieved, thereby improving the drying efficiency of the products and greatly improving the utilization rate of thermal energy. When baking multiple products, there is no need to increase the length of the entire oven, thereby greatly shortening the space occupied by the entire oven and reducing the requirements for the factory site. At the same time, the cooling box 22 also cools the products in the stacked material trays at the same time, thereby improving the cooling efficiency and reducing the space occupied by cooling, which is conducive to reducing the volume of the entire oven. In actual use, the height and number of the stacked material trays in the drying box 21 and the cooling box 22 can be increased accordingly according to the actual use requirements, and the height of the entire box body 2 can be adjusted accordingly according to the actual use requirements to meet different use requirements.

[0071] The above are only preferred embodiments of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
