Description

Technical Field

[0001] This utility model relates to the field of curing oven technology, and in particular to a curing line with recirculation. Background Technology

[0002] Curing ovens are mainly used for product drying, curing, heat treatment, temperature testing, and other constant-temperature heating. They utilize fans for convective heat exchange to transfer heat to the products. Conventional ovens primarily use hot air drying. During the drying process, a tray is often needed to carry the product into the drying work surface. After drying, the material needs to be removed from the tray, which raises the issue of tray recycling. The traditional recycling method involves collecting the trays and transporting them to the next work surface by a trolley for continued use. However, this recycling method results in the trays not being able to return to the previous work station in a timely manner for continued feeding, and it also requires manual pushing, leading to resource waste. Therefore, a curing line with recirculation is needed. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a curing line with recirculation to solve the problem of material plate recycling during the conveying process of the prior art.

[0004] To achieve the above and other related objectives, this utility model provides the following technical solution:

[0005] A curing line with reflow capability, comprising:

[0006] The curing machine body is provided with a curing chamber and a reflux chamber. The reflux chamber is located below the curing chamber and has open ends.

[0007] The recirculation chamber is equipped with a recirculation rack, on which two sets of symmetrical recirculation tracks are installed. A recirculation chain is installed inside the recirculation track. The upper end of the recirculation chain is at a higher horizontal level than the upper side of the recirculation track. A recirculation baffle is installed on the recirculation rack outside the recirculation track. The upper surface of the recirculation baffle is at a higher horizontal level than the upper side of the recirculation chain.

[0008] To achieve the above technical solution, a curing chamber and a reflux chamber are set up. The reflux chamber is used to return the material tray to the input end of the curing chamber for reloading. The reflux chain on the reflux track is used to transport the material plate. The upper end of the reflux chain is higher than the upper side of the reflux track, which allows the material plate to move with the reflux chain, thereby ensuring the conveying stability of the material tray. By setting a reflux baffle on the reflux frame outside the reflux track, displacement deviation of the material plate on the reflux chain during the reflux process can be avoided, which would affect the conveying stability of the material tray.

[0009] In one embodiment of the present invention, a return drive component is provided at one end of the return frame, and a drive shaft is provided at the movable end of the return drive component. The drive shaft is connected between the return chains of the two sets of return tracks to synchronize the movement of the two sets of return chains.

[0010] To achieve the above technical solution, a drive shaft is set at the movable end of the return drive component, and the return chains of the two sets of return tracks are driven synchronously by the drive shaft, thereby improving the synchronicity of the operation of the two sets of return chains and ensuring the stability of the material tray conveying.

[0011] In one embodiment of the present invention, a drive base is provided on the outside of the recirculation rack, and the recirculation drive component is located on the drive base.

[0012] To achieve the above technical solution, by placing the drive base outside the return frame, it is possible to avoid the return drive component affecting the conveying of the material tray by the return chain, and to provide sufficient return space for the return working surface of the return chain.

[0013] In one embodiment of the present invention, sprocket seats are provided at both ends of the return frame, a drive sprocket is provided inside the sprocket seat, and a wheel seat reinforcing plate is provided on the return frame below the sprocket seat.

[0014] To achieve the above technical solution and improve the driving stability of the return chain, a wheel seat reinforcement plate is installed on the return frame under the sprocket seat to improve the support stability of the sprocket seat, thereby ensuring stable driving of the return chain.

[0015] In one embodiment of the present invention, the curing chamber is provided with liftable sealed doors on both sides, and the curing chamber is also provided with lifting frames on both sides, with lifting drive components on the lifting frames, and the sealed doors are located at the movable end of the lifting drive components.

[0016] To achieve the above technical solution, a lifting drive component is installed that can open or close the curing chamber via the sealed door, thereby improving the curing stability of the curing chamber.

[0017] In one embodiment of the present invention, the bottom end face of the lifting frame of the curing chamber located on the upper side of the reflux chamber is set at a higher level than the reflux working surface on the upper side of the reflux track, and the bottom of the lifting drive component on the lifting frame is spaced apart from the reflux working surface on the upper side of the reflux track.

[0018] To achieve the above technical solution, the bottom end face of the lifting frame of the curing chamber located on the upper side of the reflux chamber is set to be higher than the horizontal height of the reflux working surface on the upper side of the reflux track. This provides a conveying space for the refluxed material plate, making it convenient for workers to place the material plate on the reflux track and avoiding interference from the lifting frame to the reflux of the material plate.

[0019] In one embodiment of the present invention, the bottom of the curing machine is provided with support legs to support the curing machine so that the bottom of the return chamber is spaced apart from the ground.

[0020] To achieve the above technical solution, the bottom of the recirculation chamber is spaced apart from the ground by using support legs to fix the solidified body, which can improve the stability of the recirculation chamber during use.

[0021] As described above, the curing line with reflux of this utility model has the following beneficial effects: by setting up a curing chamber and a reflux chamber, the material tray is returned to the input end of the curing chamber by the reflux chamber for reloading, and the material plate is conveyed by the reflux chain on the reflux track. The upper end of the reflux chain is higher than the upper side of the reflux track, so that the material plate can move with the reflux chain, thereby ensuring the conveying stability of the material tray. By setting a reflux baffle on the reflux frame outside the reflux track, the displacement deviation of the material plate on the reflux chain during the reflux process can be avoided, which would affect the conveying stability of the material tray.

It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] Please see Figures 1 to 2This utility model provides a curing line with reflux, including a curing machine body 1 with a curing chamber 2 and a reflux chamber 3 inside. The reflux chamber 3 is located below the curing chamber 2 and has open ends. A reflux rack 4 is provided inside the reflux chamber 3. Two sets of symmetrical reflux tracks 5 are provided on the reflux rack 4. A reflux chain 6 is provided inside the reflux track 5. The upper end of the reflux chain 6 is higher than the upper side of the reflux track 5. A reflux baffle 7 is provided on the reflux rack 4 outside the reflux track 5. The upper end of the reflux baffle 7 is higher than the upper side of the reflux chain 6.

[0028] By setting up a curing chamber 2 and a return chamber 3, the material tray is returned to the input end of the curing chamber 2 by the return chamber 3 for reloading. The material plate is conveyed by the return chain 6 on the return track 5. The upper horizontal height of the return chain 6 is higher than the upper horizontal height of the return track 5, so that the material plate can move with the return chain 6, thereby ensuring the conveying stability of the material tray. By setting a return baffle 7 on the return frame 4 outside the return track 5, the displacement deviation of the material plate on the return chain 6 during the return process can be avoided, which would affect the conveying stability of the material tray.

[0029] A return drive component 8 is provided at one end of the return frame 4. A drive shaft 15 is provided at the movable end of the return drive component 8. The drive shaft 15 is connected between the return chains 6 of the two sets of return tracks 5 to synchronize the movement of the two sets of return chains 6. By setting the drive shaft 15 at the movable end of the return drive component 8, the return chains 6 of the two sets of return tracks 5 are driven synchronously by the drive shaft 15, thereby improving the synchronicity of the operation of the two sets of return chains 6 and ensuring the stability of the material tray conveying.

[0030] A drive base 9 is provided on the outside of the return frame 4, and the return drive component 8 is located on the drive base 9. By setting the drive base 9 on the outside of the return frame 4, the return drive component 8 can avoid affecting the conveying of the material tray by the return chain 6, and provide sufficient return space for the return working surface of the return chain 6.

[0031] The return frame 4 is provided with sprocket seats 11 at both ends, and a drive sprocket is provided inside the sprocket seat 11. A wheel seat reinforcing plate 10 is provided on the return frame 4 below the sprocket seat 11. In order to improve the driving stability of the return chain 6, the wheel seat reinforcing plate 10 is provided on the return frame 4 below the sprocket seat 11 to improve the support stability of the sprocket seat 11, thereby ensuring the stable driving of the return chain 6.

[0032] The curing chamber 2 is equipped with liftable sealing doors 12 on both sides, and lifting frames 13 are also provided on both sides of the curing chamber 2. Lifting drive components 16 are provided on the lifting frames 13. The sealing doors 12 are located at the movable end of the lifting drive components 16. By setting the lifting drive components 16, the sealing doors 12 can be driven to open or close the curing chamber 2, thereby improving the curing stability of the curing chamber 2.

[0033] The lifting frame 13 of the curing chamber 2 located on the upper side of the reflux chamber 3 has its bottom end face horizontally higher than the horizontal height of the reflux working surface on the upper side of the reflux track 5. Furthermore, the bottom of the lifting drive component 16 on the lifting frame 13 is spaced apart from the reflux working surface on the upper side of the reflux track 5. By setting the bottom end face of the lifting frame 13 of the curing chamber 2 located on the upper side of the reflux chamber 3 to be higher than the horizontal height of the reflux working surface on the upper side of the reflux track 5, a conveying space can be provided for the refluxed material plate, making it convenient for workers to place the material plate on the reflux track 5 and avoiding interference from the lifting frame 13 to the reflux of the material plate.

[0034] The bottom of the curing unit 1 is provided with support legs 14 to support the curing unit 1 so that the bottom of the return chamber 3 is spaced apart from the ground. By using support legs 14 to space the bottom of the return chamber 3 from the ground, the stability of the return chamber 3 in use can be improved.

[0035] This invention features a curing chamber and a reflux chamber. The reflux chamber returns the material tray to the input end of the curing chamber for reloading. The reflux chain on the reflux track transports the material plate, and the upper end of the reflux chain is positioned higher than the upper side of the reflux track, allowing the material plate to move with the reflux chain and ensuring the stability of the material tray's transport. By installing a reflux baffle on the reflux frame outside the reflux track, displacement deviation of the material plate on the reflux chain during the reflux process can be avoided, thus preventing any impact on the stability of the material tray's transport.

[0036] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. All equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
