[0002] The steel pretreatment line process refers to the processing technology of shot blasting and rust removal on the surface of steel and applying a layer of protective primer before processing. The pretreatment of steel can improve the corrosion resistance of mechanical products and metal components, improve the fatigue resistance of steel plates, and extend their service life. At the same time, it can also optimize the surface process manufacturing state of steel, which is conducive to CNC cutting machine unloading and precision blanking. In addition, since the shape of steel before processing is relatively regular, it is conducive to mechanical rust removal and automatic painting. Therefore, the use of steel pretreatment can greatly improve the efficiency of cleaning work and reduce the labor intensity of cleaning work and pollution to the environment.

[0003] During the processing of the steel plate pretreatment line in the prior art, the steel plate is shot blasted and then painted, but its surface is still easily scratched, which will also damage the protective paint film of the steel plate, and most of the existing pretreatment production lines do not have an oil removal function, which results in some steel plates that are stained with oil during transportation failing to achieve the pretreatment effect, affecting the quality of shot blasting and spraying protective paint, and is not conducive to efficient production. For this reason, we propose a steel plate pretreatment line transportation device with a protective structure. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 In this embodiment, a steel plate pretreatment line transport device with a protective structure includes a transport box 1, a transport trough 2 is provided on the top of the transport box 1, an auxiliary wheel 10 is movably connected to the top of the transport box 1, a coating box 11 is fixedly connected to the top of the transport box 1, a flattening structure 18 is fixedly connected to the inner side of the transport trough 2, and a fan 19 is fixedly connected to the inner top wall of the coating box 11;

[0022] The flattening structure 18 includes a connecting frame 1801, the connecting frame 1801 is fixedly connected inside the transport trough 2, the top of the connecting frame 1801 is fixedly connected to a support plate 1802, an adjustment slot 1803 is fixedly provided inside the support plate 1802, the top of the connecting frame 1801 is fixedly connected to a base 1804, the top of the base 1804 is fixedly connected to a spring 1805, the inside of the adjustment slot 1803 is movably connected to an adjustment shaft 1806, the top of the spring 1805 is fixedly connected to a top plate 1807, and the outer surface of the adjustment shaft 1806 is movably connected to a flattening wheel 1808.

[0023] During specific implementation, fan 19 adopts the working mechanism of an electric fan, and is also equipped with an electric heating wire inside. When the electric fan is powered on, the electric heating wire begins to be electrically heated. After a period of heating, the temperature on the surface of the electric heating wire begins to rise, and heat is generated at the same time. The heat generated by the electric heating wire causes the blades inside fan 19 to rotate, causing the alkaline water used to clean oil stains on the surface of the steel plate to evaporate quickly, so that the subsequent shot blasting and painting of the steel plate can achieve better results.

[0024] A water inlet is fixedly provided on the top of the water tank 13 , a displacement sensor is fixedly installed on the top of the transport box 1 , and a laser sensor is fixedly connected to the right side surface of the coating box 11 .

[0025] When implementing, follow these steps:

[0026] 1) First, transport, place the steel plate to be processed on the top of the transport box 1, and start the motor 8 at the same time. The motor 8 drives the conveyor belt 7 and the conveyor column 6 to rotate. At this time, the steel plate moves horizontally to the left on the conveyor belt 7. At this time, when the steel plate passes through the monitoring area of ​​the position sensor, the position sensor transmits a signal to the laser sensor, and the laser sensor is in a standby state;

[0027] 2) Then spray the agent. When the steel plate is transported to the coating box 11, the laser sensor senses the movement of the steel plate (the laser irradiation starts from when the end of the steel plate reaches the conveyor belt 7), and triggers the water pump 14. At this time, the water pump 14 extracts and presses the agent inside the water tank 13, and then sprays it through the water outlet pipe 15 and the water collection box 16 to the nozzle 17;

[0028] 3) Flatten again. When the steel plate is sprayed, it continues to move to the left along with the conveyor belt 7. At this time, the steel plate contacts the flattening wheel 1808. The flattening wheel 1808 drives the adjustment shaft 1806, the top plate 1807, and the spring 1805 to move in the adjustment groove 1803 according to the thickness of the steel plate. When the height of the flattening wheel 1808 is equal to the thickness of the steel plate, the flattening wheel 1808 rolls along with the movement of the steel plate and spreads the agent sprayed on the steel plate evenly.

[0029] 4) Finally, air-dry and start the fan 19. At this time, the heating wire inside it begins to be electrically heated. After a period of heating, the temperature of the surface of the heating wire begins to rise and heat is generated at the same time. The heat generated by the heating wire causes the fan blades inside the fan 19 to rotate, so that the alkaline water used to clean the oil stains on the surface of the steel plate evaporates quickly, so that the subsequent shot blasting and painting of the steel plate can achieve better results.

[0030] To sum up, the steel plate pretreatment line transportation device with a protective structure optimizes the degreasing process of the steel plate pretreatment production line by setting a flattening structure 18. During the processing, the conveyor belt 7 drives the steel plate to move to the left, and drives the flattening wheel 1808 to horizontally flatten the agent on the surface of the steel plate. The excess agent is transported to the drain trough 9 under the action of the flattening wheel 1808. No manual operation is required, and the agent can be evenly spread on the steel plate. At the same time, the risk of scratching the steel plate is avoided, the labor intensity of the staff is reduced, and the work efficiency is improved.

[0031] In addition, by setting the dust curtain 12 fan 19, when the leveling wheel 1808 spreads the agent sprayed on the steel plate evenly, the subsequent hot air will quickly evaporate the alkaline water used to clean the oil stains on the steel plate, so that the subsequent shot blasting and painting of the steel plate can achieve better results, thereby increasing the integrity of the production line. At the same time, the setting of the leveling structure 18 is used to avoid the transmission phenomenon of overlapping or misplaced steel plates, thereby facilitating subsequent processing.
