The transmission structure is arranged between the No. 1 material transport roller 8 / No. 2 material transport roller 9 and the cooling components. When the No. 1 material transport roller 8 / No. 2 material transport roller 9 moves, the transmission structure controls the cooling components to work synchronously. The refrigeration box 3 is arranged on the cooling box 2 and is connected to the cooling components.

[0036] In a specific case of the present embodiment, each group of the cooling components includes a cooling seat 10, a circulating water pipe 14, a fixed seat 15 and a water drive module. The cooling seat 10 is arranged in a cooling box 2. The interior of the cooling seat 10 is hollow and is provided with a channel for the strip spray to pass through. Both ends of the cooling seat 10 are provided with through windows 18. The circulating water pipe 14 is arranged in the cooling box 2. The fixed seat 15 connects the circulating water pipe 14 and the cooling box 2. The two ends of the circulating water pipe 14 are respectively connected to the through windows 18 on both sides of the cooling seat 10. The water drive module is arranged on the circulating water pipe 14 and is connected to the transmission structure. When the transmission structure is working, it controls the water drive module to work synchronously and input flowing water into the channel.

[0037] In another specific case of the present embodiment, the water drive module includes a water pumping box 27, a movable seat 28, an extrusion plate 29 and an adjustment structure. The water pumping box 27 is arranged on the circulating water pipe 14. A partition is arranged in the circulating water pipe 14 and the circulating water pipe 14 is divided into two cavities.

As for the specific model parameters of the stepper motor 7, the best choice can be made according to the actual situation, and no specific limitation is made here.

[0039] In actual application, multiple cooling boxes 2 can be connected by utilizing the cooperation between the plug plate 4 and the slots on the matching seat 5. By controlling the temperature of the refrigeration box 3 on the cooling box 2 at different positions, the temperature of the water in the cooling box 2 is adjusted, so that the temperature of the adjacent cooling boxes 2 changes step by step; by controlling the rotation of the stepper motor 7, the No. 1 material transport roller 8 and the No. 2 material transport roller 9 are rotated, so as to transport the strip spray material for feeding; when the No. 1 material transport roller 8 moves, the transmission structure is controlled to work, and the operation of the transmission structure can control the operation of the adjustment structure, so that the movable seat 28 and the extrusion plate 29 reciprocate along the water pumping box 27, so as to control the water flow between the circulating water pipe 14, the water pumping box 27 and the cooling seat 10. Since the flow direction of the water flow is opposite to the feeding direction of the strip spray material, and the flow velocity V1 of the flowing water flow is less than the feeding velocity V2 of the strip spray material, a resistance can be provided to the strip spray material. In this process, by increasing the resistance of the water flow, the phenomenon of the strip spray material being broken due to tension during the feeding process can be effectively avoided.

[0040] See also Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 as well as Figure 8 As another preferred embodiment of the present application, the adjustment structure includes a reciprocating screw 30, a driving wheel 20, a driven wheel 21 and an output shaft 19, the reciprocating screw 30 is movably arranged on the fixed seat 15, the movable seat 28 is sleeved on the reciprocating screw 30 and the two are threadedly matched, the driven wheel 21 is movably arranged on the fixed seat 15 and is coaxially connected to the reciprocating screw 30, the driving wheel 20 is movably arranged on the fixed seat 15 and meshes with the driven wheel 21, the driving wheel 20 and the driven wheel 21 are both bevel gears, and the output shaft 19 is movably arranged on the fixed seat 15 and connected between the driving wheel 20 and the transmission structure.

[0042] In the process of the stepper motor 7 controlling the No. 1 material transport roller 8 to rotate to transport the strip spray material, it can drive the turntable 31 to rotate. When the turntable 31 rotates, the cooperation between the movable head 32 and the movable arm 33 can make the curved shaft 34 rotate, thereby driving the No. 2 transmission wheel 35 to rotate. Under the action of the No. 2 belt and the No. 1 belt 12, the No. 1 transmission wheel 11 is controlled to rotate, so that the output shaft 19 and the driving wheel 20 rotate.
