[0032] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0033] See attached document Figure 1 - Appendix Figure 8 This utility model provides a curing device for a rust-proof coating on cold-rolled steel sheets, comprising:
[0034] Curing chamber 1, with the front side of curing chamber 1 being open;
[0035] Heat pump 2 is fixedly connected to one side of curing chamber 1. The air outlet of heat pump 2 is fixedly connected to pipe 3, which is L-shaped and fixedly connected to the top of curing chamber 1.
[0036] There are two support rods 4, which are fixedly connected to the inner walls of the two sides of the curing box 1 respectively. A reciprocating screw 5 is connected to the rear side of each support rod 4. The two reciprocating screws 5 pass through the rear side of the curing box 1. A sliding seat 6 is sleeved on the outside of each reciprocating screw 5. The sliding seat 6 is connected to the reciprocating screw 5 through a ball screw pair. A movable plate 7 is fixedly connected to the bottom of each sliding seat 6.
[0037] Pipe 2 8 is located at the bottom of the movable plate 7. A connecting component is provided between pipe 2 8 and the movable plate 7. Multiple through holes are opened at the bottom of pipe 2 8. Two flexible hoses 9 are fixedly connected between pipe 2 8 and pipe 1 3.
[0038] Both hoses 9 pass through the top of the curing chamber 1 and are fixedly connected to it. An exhaust hole is provided on the other side of the curing chamber 1. A door 10 is provided on the front side of the curing chamber 1. The door 10 is connected to the curing chamber 1 by a hinge.
[0039] In this implementation scheme, pipe 3 and two hoses 9 are designed so that when heat pump 2 is working, hot air can enter pipe 8 and be ejected from the through hole. At the same time, the two reciprocating screws 5 are controlled to rotate, so that the two sliding seats 6, the moving plate 7 and pipe 8 move back and forth continuously. This allows the position of the through hole to change continuously, so that the hot air can be blown evenly on the surface of the steel plate during curing. This prevents the phenomenon of incomplete curing or over-curing in some areas.
[0040] To achieve the simultaneous rotation of the two reciprocating screws 5, the device employs the following technical solution: an L-shaped plate 11 is fixedly connected to the rear side of the curing box 1, and a motor 12 is fixedly connected to the rear side of the L-shaped plate 11. The rear end of one of the reciprocating screws 5 passes through the L-shaped plate 11 and is fixedly connected to the output shaft of the motor 12. Both reciprocating screws 5 are fixedly fitted with sprockets 13, and chains 14 are fitted on the outside of the two sprockets 13. The two sprockets 13 are driven by the chain 14. The reciprocating screws 5 are connected to the curing box 1 and the support rod 4 through bearings. The design of the motor 12, sprockets 13 and chain 14 enables the two reciprocating screws 5 to rotate simultaneously.
[0041] In order to achieve the purpose of limiting, the device adopts the following technical solution: the rear sides of the two support rods 4 are fixedly connected to the limiting rods 15, the rear ends of the two limiting rods 15 are fixedly connected to the inner wall of the rear side of the curing box 1, the two limiting rods 15 pass through the two sliding seats 6 respectively and slide in contact with them, and the top of the pipe 2 8 is fixedly connected to two sliders 16, and the two sliders 16 pass through the moving plate 7 and slide in contact with it.
[0042] To achieve the purpose of adjusting the distance between pipe 28 and placement block 28, this device adopts the following technical solution: The connecting assembly includes a threaded rod 17, which is fixedly connected to the top of pipe 28. A threaded block 18 is sleeved on the outside of the threaded rod 17, and the threaded block 18 is threadedly connected to the threaded rod 17. The threaded block 18 is embedded in the moving plate 7 and connected to it through a bearing. A knob 19 is fixedly sleeved on the outside of the threaded block 18, and a fixing ring 20 is fixedly connected to the bottom of the knob 19. A locking block 21 is slidably provided on the top of the moving plate 7, and the locking block 21 and the fixing ring 20 are connected to each other. The top of the movable plate 7 is fixedly connected to a protrusion 22. A pull rod 23 is slidably embedded on the protrusion 22 and one end of the pull rod 23 is fixedly connected to the locking block 21. A spring 24 is fixedly connected between the protrusion 22 and the locking block 21 and is sleeved on the outside of the pull rod 23. A pull block 25 is fixedly connected to one end of the pull rod 23. A groove is opened on the movable plate 7. A positioning rod 26 is fixedly connected inside the groove. A positioning block 27 is slidably sleeved on the outside of the positioning rod 26. The positioning block 27 is fixedly connected to the bottom of the locking block 21. The connecting component can adjust the distance between the pipe 28 and the placement block 28.
[0043] In order to achieve the purpose of pushing the material, the device adopts the following technical solution: a placement block 28 is fixedly connected to the bottom inner wall of the curing box 1, a push plate 29 is provided on the placement block 28, two electric push rods 30 are fixedly embedded on the rear side of the curing box 1, the front ends of the two electric push rods 30 are fixedly connected to the push plate 29, and a bracket 31 is fixedly sleeved on the outside of the two electric push rods 30, and the bracket 31 is fixedly connected to the rear side of the curing box 1.
[0044] To achieve the purpose of support, the device adopts the following technical solution: support legs 32 are fixedly connected to the four corners of the bottom of the curing box 1, and the support legs 32 can support the device.
[0045] The usage process of this utility model is as follows: When it is necessary to cure the coating on the surface of the steel plate, the steel plate is placed on the placement block 28, and then the box door 10 is closed. Then, the heat pump 2 is controlled to work, and under the action of the first pipe 3 and the two hoses 9, hot air can enter the second pipe 8. In this way, the hot air can be blown onto the steel plate through multiple through holes. Then, the motor 12 is controlled to work to make the reciprocating screw 5 on the left rotate. Then, under the action of the sprocket 13 and the chain 14, the reciprocating screw 5 on the right also rotates. In this way, both reciprocating screws 5 can rotate at the same time. The rotation of the two reciprocating screws 5 drives the two sliding seats 6 and the moving plate 7 to move back and forth continuously. Then, under the action of the connecting component and the two sliders 16, the second pipe 8 can move back and forth continuously. In this way, the position of the through holes can be changed continuously. In this way, the hot air can be blown evenly on the surface of the steel plate during curing. In this way, there will be no phenomenon of incomplete curing or over-curing in some areas. This not only ensures the quality of curing but also ensures the rust prevention ability of the coating.
[0046] After curing is complete, open the door 10 and then control the two electric push rods 30 to move the push plate 29 forward, thereby pushing the steel plate forward. This allows the front end of the steel plate to extend outside the curing box 1, making it easy to manually remove the steel plate. After removal, spray an anti-rust coating on the other side of the steel plate and then place it face up on the placement block 28. Then continue curing using the same principle.
[0047] When in use, the motor 12 can be controlled to stop the sliding seat 6, the moving plate 7, and the pipe 8 near the door 10. Then, the pull block 25 is pulled to move the pull rod 23, the locking block 21, and other components to the left. At the same time, the spring 24 is compressed, so that the locking block 21 does not contact the fixing ring 20. Then, the knob 19 is turned to make the threaded block 18 rotate. Since the threaded block 18 is embedded in the moving plate 7, it can only rotate and cannot move. The rotation of the threaded block 18 can make the threaded rod 17 move upward, and thus make the pipe 8 move upward. This allows the distance between the pipe 8 and the placement block 28 to be adjusted. In this way, the device can perform coating curing work on steel plates of different thicknesses.
[0048] After the distance adjustment is completed, release the pull block 25. Then, under the action of the spring 24, the locking block 21, the pull rod 23 and other components move to the right. In this way, the locking block 21 can press the fixing ring 20 together, thus preventing the threaded block 18 from rotating randomly, and thus preventing the distance between the pipe 28 and the placement block 28 from changing.
[0049] The above are merely preferred embodiments of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model shall fall within the scope of protection claimed by this utility model.
