[0027] 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.
[0028] See attached document Figure 1 - Appendix Figure 4 The present invention provides an improved surface pretreatment device for cold-rolled steel plates, including a positioning frame 1, which is a square structure, and multiple support legs 2 are fixedly connected to the bottom of the positioning frame 1.
[0029] The positioning and flipping mechanism is located inside the positioning frame 1. The positioning and flipping mechanism is used to fix, clamp and flip the cold-rolled steel plate.
[0030] The cleaning mechanism is located at the top of the positioning frame 1 and is used to clean the surface of the pre-treated cold-rolled steel plate.
[0031] The positioning and flipping mechanism includes two positioning clamps 3, and square rods 4 are fixedly connected to the outer side of each of the two positioning clamps 3. A horizontal plate 5 is provided on the outer side of the positioning frame 1, and the two horizontal plates 5 are fixedly connected to the outer ends of the two square rods 4 respectively.
[0032] In this embodiment, the user places the cold-rolled steel plate inside the positioning frame 1, and the cold-rolled steel plate can be clamped and fixed by the operation of the first electric push rod 10. Then, the user can turn the crank handle 16 to flip the cold-rolled steel plate.
[0033] To achieve the purpose of product positioning and flipping, this device adopts the following technical solution: The positioning and flipping mechanism also includes multiple movable rods 6, which are respectively connected to two horizontal plates 5 by hinges.

The positioning and flipping mechanism also includes a transmission shaft 13, which is located at the bottom of the positioning frame 1. A fixing plate 14 is fixedly connected between multiple legs 2. The fixing plate 14 is sleeved on the outside of the transmission shaft 13 and is movably connected to the transmission shaft 13 via a rolling bearing. A moving rod 15 is provided at one end of the transmission shaft 13. The moving rod 15 slides with the transmission shaft 13. A crank handle 16 is fixedly connected at one end of the moving rod 15. A buckle 17 is fixedly connected to the rear side of the crank handle 16. Two sleeves 18 are provided on one side of the fixing plate 14. The buckle 17 matches the sleeves 18.

[0034] The user places the cold-rolled steel plate inside the positioning frame 1 and activates multiple first electric push rods 10 to retract. The retraction of the first electric push rods 10 drives the square rod 4 and the positioning clamp 3 to move towards the center, so that the positioning clamp 3 positions and clamps the cold-rolled steel plate. At the same time, when the cold-rolled steel plate needs to be flipped, the user turns the crank handle 16, which causes the drive shaft 13 and multiple connecting pipes 7 to rotate, thereby causing the cold-rolled steel plate to flip.

A movable plate 31 is provided at the inner end of the two second electric push rods 30. The movable plate 31 is fixedly connected to the connecting frame 23.
[0036] The user activates the hydraulic rod to retract, causing the stabilizing plate 27 and cleaning brush 21 to move downwards, so that the cleaning brush 21 contacts the cold-rolled steel plate. At this time, the user activates the second electric push rod 30 to retract, causing the connecting frame 23 to move. The movement of the connecting frame 23 causes the gear 29 to rotate on the surface of the toothed plate 28, causing the gear 29 and the transmission rod 22 to rotate. The rotation of the transmission rod 22 drives the cleaning brush 21 to rotate and brush the surface of the cold-rolled steel plate.
[0037] The usage process of this utility model is as follows: The user places the cold-rolled steel plate inside the positioning frame 1. The first electric push rod 10 clamps and fixes the cold-rolled steel plate. Then, the user can rotate the crank handle 16 to flip the cold-rolled steel plate. When the user places the cold-rolled steel plate inside the positioning frame 1 and activates the retraction of multiple first electric push rods 10, the retraction of the first electric push rods 10 drives the square rod 4 and the positioning clamp 3 to move towards the center, so that the positioning clamp 3 positions and clamps the cold-rolled steel plate. Simultaneously, when it is necessary to flip the cold-rolled steel plate, the user rotates the crank handle 16, causing the transmission... The rotating shaft 13 and multiple connecting pipes 7 rotate, thereby causing the cold-rolled steel plate to flip. After flipping, the user presses the rocker handle 16, causing the buckle 17 to be inserted into the sleeve 18. The user activates the hydraulic rod to retract, causing the stabilizing plate 27 and the cleaning brush 21 to move down, so that the cleaning brush 21 contacts the cold-rolled steel plate. At this time, the user activates the second electric push rod 30 to retract, causing the connecting frame 23 to move. The movement of the connecting frame 23 causes the gear 29 to rotate on the surface of the toothed plate 28, causing the gear 29 and the transmission rod 22 to rotate. The rotation of the transmission rod 22 drives the cleaning brush 21 to rotate and brush the surface of the cold-rolled steel plate.
[0038] The above description is merely a preferred embodiment 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 are within the scope of protection claimed by this utility model.
