[0022] The embodiment of the present application provides a cooling device for the production of laminated stainless steel plates, which effectively solves the above-mentioned cooling device. The steel plate is directly cooled by water cooling, and the cooling speed is fast, which will cause the temperature difference between the inside and outside of the laminated steel plate to be too large. The large temperature difference between the inside and outside will cause the steel plate to be delaminated or deformed and bent, reducing the qualified rate of steel plate production. The first temperature sensor, the second temperature sensor, and the stepper motor are connected to the PLC controller and the computer. The first temperature sensor at the top of the upper heating plate is set by the PLC controller and the computer to maintain the temperature of each group of heating plates within the set range. The temperature of the first group of heating plates is slightly lower than the initial temperature of the steel plate, and the temperature of the latter group of heating plates is slightly lower than the previous group of heating plates. The temperature difference between the two adjacent groups of heating plates is controlled according to the characteristics of each layer of the laminated stainless steel plate. The last group of heating plates is cooled. By installing multiple groups of heating plates and multiple first temperature sensors inside the cooling zone, the temperature inside the cooling zone can be adjusted according to demand, achieving the effect of being able to be adjusted according to production needs. In the initial state, the sliding frame stays in the feeding area, and the produced steel plates are placed in the feeding area. On the top, rotating the knob drives the threaded rod to rotate, pushing the clamping plate to slide and clamp the steel plate, the stepper motor starts to drive the gear to rotate, and the gear will drive the sliding frame to slide into the cooling zone to between the first group of heating plates through meshing with the rack. After the steel plate reaches the specified position, the stepper motor stops. At this time, the corresponding second temperature sensor will monitor the temperature of the steel plate. When the temperature of the steel plate drops to the set temperature, the stepper motor restarts and drives the steel plate to slide between the next group of heating plates through the gear until the temperature of the steel plate drops to the required level. The stepper motor drives the steel plate to slide to the material removal area, and the rotating knob drives the threaded rod to rotate, and pulls the clamping plate to take out the steel plate to complete the cooling. The stepper motor drives the steel plate to slide inside the cooling zone to complete the step-by-step cooling of the steel plate, thereby achieving the effect of improving the production pass rate of laminated stainless steel plates.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the technical solution in the embodiment of the present application effectively solves the above-mentioned cooling device, which directly cools the steel plate by water cooling. The cooling speed is fast, which will cause the temperature difference between the inside and outside of the laminated steel plate to be too large. The large temperature difference between the inside and outside will cause the steel plate to be delaminated or deformed and bent, reducing the qualified rate of steel plate production. The overall idea is as follows:

[0025] In view of the problems existing in the prior art, the utility model provides a cooling device for the production of laminated stainless steel plates, including a cooling box 1, the cooling box 1 includes a cooling zone 101, a feeding zone 102, and a taking zone 103, a sliding frame 2 is slidably installed inside the cooling box 1, a plurality of heating plates 6 are symmetrically fixedly installed in the upper and lower parts of the cooling zone 101, and a rack 7 is fixedly installed on the side end of the cooling box 1; the upper and lower heating plates 6 are connected in series as a group through a wire, a plurality of first temperature sensors 9 are fixedly installed in the cooling zone 101, and a plurality of second temperature sensors 11 are fixedly installed in the cooling zone 101.

[0026] Each first temperature sensor 9 and second temperature sensor 11 corresponds to a group of heating plates 6 respectively. The first temperature sensor 9 is located at the top of the upper heating plate 6, and the second temperature sensor 11 is located between the upper and lower heating plates 6. Two clamping plates 3 are symmetrically slidably installed inside the sliding frame 2, and two threaded rods 4 are symmetrically threadedly installed on both sides of the sliding frame 2; the ends of the threaded rods 4 are rotatably connected to the clamping plates 3.

[0027] The feeding area 102 is opened at the side end of the cooling area 101, and the material taking area 103 is opened at the side end of the cooling area 101. The side end of the sliding frame 2 is fixedly installed with a stepper motor 5, and the side end of the stepper motor 5 is fixedly installed with a gear 8; the gear 8 is meshed with the rack 7, and the side ends of the two threaded rods 4 are fixedly installed with knobs 12.

[0028] Working principle:

[0029] In the first step, the first temperature sensor 9, the second temperature sensor 11, and the stepper motor 5 are connected to the PLC controller and the computer. Under the settings of the PLC controller and the computer, the first temperature sensor 9 at the top of the upper heating plate 6 maintains the temperature of each group of heating plates 6 within the set range. The temperature of the first group of heating plates 6 is slightly lower than the initial temperature of the steel plate, and the temperature of the latter group of heating plates 6 is slightly lower than the former group of heating plates 6. The temperature difference between the two adjacent groups of heating plates 6 is controlled according to the characteristics of each layer of material of the laminated stainless steel plate, and the last group of heating plates 6 is cooled. By installing multiple groups of heating plates 6 and multiple first temperature sensors 9 inside the cooling zone 101, the temperature inside the cooling zone 101 can be adjusted step by step according to demand, thereby achieving the effect of being able to be adjusted according to production needs.

[0030] The second step, in the initial state, the sliding frame 2 stays in the feeding area 102, and the produced steel plate is placed on the feeding area 102. The rotating knob 12 drives the threaded rod 4 to rotate, and the clamping plate 3 is pushed to slide to clamp the steel plate. The stepper motor 5 starts to drive the gear 8 to rotate. The gear 8 drives the sliding frame 2 to slide into the cooling zone 101 to the first group of heating plates 6 through the engagement with the rack 7. After the steel plate reaches the specified position, the stepper motor 5 stops. At this time, the corresponding second temperature sensor 11 will monitor the temperature of the steel plate. When the temperature of the steel plate drops to the set temperature, the stepper motor 5 restarts and drives the steel plate to slide between the next group of heating plates 6 through the gear 8 until the temperature of the steel plate drops to the required level. The stepper motor 5 drives the steel plate to slide to the material removal area 103, and the rotating knob 12 drives the threaded rod 4 to rotate, and pulls the clamping plate 3 to take out the steel plate to complete the cooling. The stepper motor 5 drives the steel plate to slide inside the cooling zone 101 to complete the step-by-step cooling of the steel plate, thereby achieving the effect of improving the qualified rate of laminated stainless steel plate production.

For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
