Description

Technical Field

[0001] This invention relates to the field of curing oven technology, and specifically to a synchronous vertical lifting conveyor curing oven. Background Technology

[0002] A curing oven is a heat treatment device used to harden or cure materials (such as coatings, adhesives, composites, etc.) by causing physical or chemical changes under specific temperature and time conditions. It is widely used in industries such as electronics, automotive, aerospace, and building materials, playing a crucial role in processes such as PCB manufacturing, powder coating, and carbon fiber prepreg curing. Curing ovens typically feature precise temperature control systems, uniform heating performance, and programmable process parameters to ensure the consistency and reliability of product curing quality.

[0003] In existing curing ovens, the feeding of workpieces typically relies on operators manually placing each workpiece onto a conveyor (such as a mesh belt, chain, or roller). Operators often struggle to maintain proper spacing between workpieces during placement, leading to adjacent workpieces being too close together or even touching. This dense arrangement not only affects the uniform flow of hot air or radiant heat within the oven cavity, reducing curing efficiency and quality, but can also cause blockages, shutdowns, or even equipment damage during transport due to workpiece jamming, tipping, or stacking, thus impacting the continuity and stability of the entire production line. Summary of the Invention

[0004] To address the aforementioned shortcomings of existing technologies, this invention provides a synchronous vertical lifting and conveying curing oven. This effectively solves the problem that existing curing ovens typically rely on manual placement of workpieces onto the conveying device, making it difficult to ensure proper spacing between workpieces and easily leading to contact or sticking together. This dense arrangement not only affects the uniformity of heat flow within the oven and reduces curing quality, but may also cause jamming, blockages, or even equipment malfunctions, affecting production continuity.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a synchronous vertical lifting conveyor curing oven, including a processing box. First conveying devices are installed on both the left and right sides of the processing box. A second conveying device is installed on one side of each of the first conveying devices. Each of the first and second conveying devices is equipped with a sorting assembly. Each sorting assembly includes four fixed plates. A running plate is rotatably connected to one side of each fixed plate. Limiting plates are fixedly connected to both the left and right sides of the second conveyor. A push frame is slidably connected to one side of each limiting plate. A partition is fixedly connected to one side of each push frame. A first mounting frame is fixedly connected to the top of each limiting plate. A detection component is installed at the bottom of the first mounting frame. A first transmission rod and a second transmission rod are rotatably connected to the bottom of the second conveyor. A lifting assembly is provided inside the processing box.

[0006] Furthermore, heating devices are installed on both sides of the processing box, a mounting rod is fixedly connected to one side of the running plate, a running groove is opened on one side of the push frame and slidably connected to the mounting rod, gears are fixedly connected to the outer surfaces of the first transmission rod and the second transmission rod respectively, and the two gears mesh, and guide plates are fixedly connected to the outer surfaces of the first transmission rod and the second transmission rod.

[0007] Furthermore, a positioning plate is fixedly connected to one side of the guide plate, and a connecting plate is fixedly connected to one side of the running plate. One side of the connecting plate is rotatably connected to the positioning plate.

[0008] Furthermore, a round rod is rotatably connected to the bottom of the second conveying device, and bevel gears are fixedly connected to the outer surfaces of the round rod and the second transmission rod, and the two bevel gears mesh.

[0009] Furthermore, support frames are fixedly connected to both the left and right sides of the second conveying device, one side of the support frame is slidably connected to the connecting plate, and a second mounting frame is fixedly connected to the top of the first conveying device.

[0010] Furthermore, a threaded rod is rotatably connected to the bottom of the second mounting frame, and a first synchronous pulley is respectively installed at one end of the threaded rod and the round rod, and the two first synchronous pulleys are connected by a synchronous belt drive.

[0011] Furthermore, a first motor is fixedly connected to one side of the second mounting frame, the output shaft of the first motor is fixedly connected to a threaded rod, and two threaded plates are threadedly connected to the outer surface of the threaded rod, with both sides of the threaded plates slidably connected to the second mounting frame.

[0012] Furthermore, a fixing rod is fixedly connected to one side of the threaded plate, and a clamping plate is fixedly connected to one side of the fixing rod.

[0013] Furthermore, the lifting assembly includes four long rods, two of which are respectively equipped with second synchronous pulleys on their outer surfaces, and the two second synchronous pulleys are connected by a synchronous belt drive. The left and right sides of the processing box are fixedly connected with second motors, the output shafts of the second motors are fixedly connected to the long rods, and the outer surfaces of the four long rods are respectively fixedly connected with driving sprockets and driven sprockets.

[0014] Furthermore, the outer surfaces of the driving sprocket and the driven sprocket are connected to a chain, and a number of chain plates are fixedly connected to the outer surface of the chain. Electric guide rails are installed on both the front and rear sides of the inner cavity of the processing box, and a push plate is installed on one side of the electric guide rail.

[0015] Beneficial effects The technical solution provided by this invention has the following advantages compared with the known prior art: I. This invention achieves control over the processed workpiece during transport by organizing the guide plate, partition, and clamping plate in the assembly. Specifically, the partition periodically physically separates adjacent workpieces under drive, effectively preventing them from sticking together or stacking due to insufficient spacing. Subsequently, the clamping plate applies stable clamping force synchronously from both sides of the workpiece, preventing it from tilting, shifting, or tipping over during transport. This not only significantly reduces the risk of blockage caused by disordered workpiece arrangement during the feeding stage, but also ensures the smooth operation of the subsequent curing process, thereby improving the overall processing efficiency of the equipment.

[0016] Second, this invention further utilizes the chain plate, long rod, and other structures in the lifting assembly. When the workpiece is orderly fed into the processing box, the chain plate, driven by the motor and chain, drives the workpiece to rise and fall smoothly in the vertical direction, allowing it to fully and evenly receive heat radiation or hot air in the heating area, ensuring the consistency and integrity of the curing effect. At the same time, the sorting assembly has completed the spacing control and posture correction of the workpiece at the front end, providing standardized feeding conditions for the lifting assembly. With the combined use of the two, precise planning and efficient flow of processing positions are achieved, greatly improving the production cycle and process stability of the whole machine.

[0025] See attached document Figure 2-7 A threaded rod 417 is rotatably connected to the bottom of the second mounting frame 416. The outer surface of the threaded rod 417 has two oppositely arranged external threads. One end of the threaded rod 417 and the round rod 413 are respectively equipped with a first synchronous pulley 418, and the two first synchronous pulleys 418 are connected by a synchronous belt drive. A first motor 419 is fixedly connected to one side of the second mounting frame 416. The output shaft of the first motor 419 is fixedly connected to the threaded rod 417. Two threaded plates 420 are threadedly connected to the outer surface of the threaded rod 417. The two threaded plates 420 have internal threads that are threadedly connected to the threaded rod 417 at the contact points. Both sides of the threaded plates 420 are slidably connected to the second mounting frame 416. Guide grooves that are slidably connected to the threaded plates 420 are opened on both the left and right sides of the second mounting frame 416. A fixing rod 421 is fixedly connected to one side of the threaded plate 420.

[0026] See attached document Figure 1-8 A clamping plate 422 is fixedly connected to one side of the fixed rod 421. The clamping plate 422 is used to clamp the two sides of the workpiece with a large width, thereby arranging and transferring the workpiece to facilitate its entry into the inner cavity of the processing box 1 for processing. The lifting assembly 5 includes four long rods 51, and the four long rods 51 are rotatably connected to the inner cavity of the processing box 1. The outer surfaces of two long rods 51 are respectively equipped with second synchronous pulleys 52, and the two second synchronous pulleys 52 are connected by synchronous belt drive. One end of the two long rods 51 penetrates the outer side of the inner cavity of the processing box 1, and the part that penetrates and contacts the processing box 1 is sealed, such as with a sealed bearing or a skeleton oil seal. The left and right sides of the processing box 1 are fixedly connected with second motors 53. The output shaft of the second motors 53 is fixedly connected to the long rods 51. The outer surfaces of the four long rods 51 are respectively fixedly connected with a drive sprocket 54 and a driven sprocket 55. The outer surfaces of the drive sprocket 54 and the driven sprocket 55 are connected by a chain 56.

[0027] See attached document Figure 2-8 Several chain plates 57 are fixedly connected to the outer surface of the chain 56. The chain plates 57 are aligned with the discharge and feed ports on the left and right sides of the processing box 1 to transfer and fix the processed workpiece. Displacement sensors are installed at the discharge and feed ports. A placement groove is opened on one side of the chain plate 57 to place the processed workpiece. The cross-section of the chain plate 57 is higher than that of the chain 56 to avoid it being installed on the same horizontal plane as the chain 56. Electric guide rails 58 are installed on the front and rear sides of the inner cavity of the processing box 1. A push plate 59 is installed on one side of the electric guide rail 58. A displacement sensor is installed at the bottom of the push plate 59 to push the processed workpiece placed in the placement groove of the chain plate 57. The lifting assembly 5 is treated with high temperature resistance, for example, by using a high temperature resistant coating or high temperature resistant materials for the assembly parts.

[0028] Specifically, during the process of the second conveying device 3 conveying the workpiece to the inlet of the first conveying device 2 and the processing box 1, the detection component 47 first monitors the transmission status of the workpiece in real time. When the workpiece is detected to be in place, the first motor 419 is started. The first motor 419 drives the threaded rod 417 and the first synchronous wheel 418 to rotate synchronously: the threaded rod 417 pushes two threaded plates 420 to move relative to or away from each other along its axial direction through threaded engagement; the threaded plates 420 then drive the fixed rod 421 and the clamping plate 422 to move synchronously, so that the clamping plate 422 stably clamps the workpiece from both sides, effectively preventing it from tilting or deviating during transmission.

[0029] Simultaneously, the first synchronous pulley 418 drives the round rod 413 to rotate via transmission, and the round rod 413 further drives the bevel gear 414 to rotate; the bevel gear 414 meshes and drives the second transmission rod 49 to rotate, and the second transmission rod 49 then drives the gear 410 to rotate; the gear 410 is linked with the guide plate 411, causing the guide plate 411 to swing. The guide plate 411 pushes the positioning plate 423 to move, and the positioning plate 423 then pushes the connecting plate 412 to move. The connecting plate 412 rotates around the connection point with the fixed plate 41, causing the running plate 42 to swing back and forth; the running plate 42 synchronously pushes the mounting rod 424 to move, and the mounting rod 424 drives the push frame 44 and the partition plate 45 to move in the back and forth direction. Through the above-mentioned linkage mechanism, the two partition plates 45 effectively separate adjacent processed materials, ensuring that they maintain a reasonable distance during the feeding process and avoiding blockage or transmission errors caused by contact.

[0030] After clamping and separating, the workpiece is conveyed in an orderly manner to the first conveying device 2 and then fed into the inner cavity of the processing box 1. At this time, the workpiece is placed in the placement slot on the chain plate 57. Subsequently, the second motor 53 is started, which drives the second synchronous wheel 52 and the drive sprocket 54 to rotate synchronously; the drive sprocket 54 drives the driven sprocket 55 through the chain 56, thereby driving the entire chain 56 and chain plate 57 to achieve vertical lifting and lowering movement, so that the workpiece rises or falls smoothly in the heating area.

[0031] During this process, the heating device 11 is activated simultaneously to perform uniform and efficient heat curing treatment on the processed material. After the heating process is completed, the electric guide rail 58 is activated, driving the pusher plate 59 to move horizontally along the discharge port of the processing box 1; the pusher plate 59 acts on the left side of the processed material, smoothly pushing it out to complete the discharge process. This achieves precise positioning, effective isolation, and stable operation of the processed material throughout the entire process of feeding, conveying, curing, and discharging, significantly improving the production efficiency of the curing oven.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
