[0029] The following will refer to the attached Figures 1 to 5 The utility model is described in detail with reference to the embodiments. Figure 1 As shown, the direction indicated by x is the front of the utility model

[0030] In general, the utility model relates to a cold rolling oil recovery device, which is used for collecting residual oil droplets on the surface of the plate after cold rolling. It includes a shell 1, an upper connecting pipe 2 fixedly arranged on the inner top surface of the shell 1, a lower connecting pipe 201 fixedly arranged on the inner bottom surface of the shell 1, a collecting device connected to the upper connecting pipe 2 and the lower connecting pipe 201, a lower scraper 604 fixedly connected to the inner wall of the shell 1 on two opposite sides, a lower slot 606 provided on the lower scraper 604, a lower sliding block 701 symmetrically slidably arranged in the lower slot 606, and a sliding rod 9 slidably connected to each lower sliding block 701; wherein, an upper scraper 6 is provided above the lower scraper 604, an upper slot 601 is provided on the upper scraper 6, an upper sliding block 7 is symmetrically slidably connected in the upper slot 601, and the top end of the sliding rod 9 is fixedly connected to the bottom surface of the upper sliding block 7, and the upper sliding block 7 is opposite to the lower sliding block 701;

[0031] Based on the above settings, Figure 2 As shown, the upper connecting pipe 2 is connected to an upper air suction hood 4 with an opening facing downward, and the upper air suction hood 4 is on the front side of the upper scraper 6. The lower connecting pipe 201 is connected to upper and lower air suction hoods 401 with an opening facing upward, and the lower air suction hood 401 is on the front side of the upper scraper 6.

[0032] In this embodiment, the housing 1 serves to shield and fix the entire device. After the plate is sent out from the cold rolling roller of the cold rolling mill, it will enter between the upper scraper 6 and the lower scraper 604, and abut against the upper and lower surfaces of the plate. As the plate is transported, the oil droplets on the plate will be scraped off. The upper suction hood 4 and the lower suction hood 401 are arranged on the front side of the upper scraper 6 and the lower scraper 604 to collect the scraped oil droplets into the collection device. In addition, when the plate enters between the upper scraper 6 and the lower scraper 604, the sliding rods 9 on the left and right sides will abut against the left and right side walls of the plate to scrape off the oil droplets remaining on the left and right side walls.

[0033] like Figure 4 As shown, the upper sliding block 7 and the lower sliding block 701 slide in the upper slot 601 and the lower slot 606, and the spacing between the sliding rods 9 can be adjusted to adapt to plates of different widths. The upper scraper 6 is connected to the sliding rod 9 on the lower scraper 604 by sliding upward, thereby adjusting the spacing between the upper scraper 6 and the lower scraper 604 to adapt to plates of different thicknesses. In order to facilitate the stability of the spacing between the upper scraper 6 and the lower scraper 604 after adjustment, in this embodiment, a screw rod 8 is screwed on the lower sliding block 701, and the top end of the screw rod 8 is rotatably connected to the bottom surface of the upper sliding block 7, and the screw rod 8 is located on the side of the sliding rod 9 away from the other side of the sliding rod 9.

[0034] When implementing it, Figure 1 and Figure 2As shown, the upper air intake hood 4 and the lower air intake hood 401 are connected to the upper connecting pipe 2 and the lower connecting pipe 201 through the connecting pipe 3. The upper connecting rod is inside the shell 1, and extends backward along the front and rear length direction of the shell 1 to the rear side of the shell 1 and is connected to the collecting device.

[0035] It should be noted that if Figure 1 As shown, the above-mentioned collecting device includes a fan 10 connected with an upper connecting pipe 201 and a lower connecting pipe 201, and a storage tank 1001 connected with the fan 10. The specific working principle is: by turning on the power supply, the motor rotates at a high speed, the fan blades of the fan 10 rotate, and the air is discharged at a high speed, while the air in the dust suction part at the front end of the fan 10 continues to replenish the air of the fan 10, resulting in an instantaneous vacuum inside, forming a negative pressure difference with the outside, and sucking the oil droplets into the storage tank 1001.

[0036] In actual use, the cold rolling mill's cold rolling rollers will also be stained with cold rolling oil. If they are not cleaned for a long time, it will affect the normal operation of the cold rolling rollers and the cold rolling yield rate. Figure 2 and Figure 3 As shown, the ends of the upper connecting pipe 2 and the lower connecting pipe 201 extend close to the cold rolling roller and are provided with an upper wheel cover 5 and a lower wheel cover 501 respectively contacting the cold rolling roller. The upper wheel cover 5 and the lower wheel cover 501 are connected with the upper connecting pipe 2 and the lower connecting pipe 201, and the top surface of the upper wheel cover 5 has an opening, which can scrape the cold rolling oil on the cold rolling roller and then suck it into the collection device.

[0037] like Figure 4 and Figure 5 As shown, this embodiment also includes elastic devices respectively arranged in the upper slot 601 and the lower slot 606, which can provide clamping force for the upper sliding block 7 and the lower sliding block 701, so that the plate is more stable between the upper scraper 6 and the lower scraper 604. It includes a fixed block 602 fixedly arranged in the middle position of the upper slot 601 or the lower slot 606, the fixed block 602 is between the upper sliding block 7 or the lower sliding block 701, and a tension spring 603 is arranged between the fixed block 602 and the upper sliding block 7 or the lower sliding block 701.

[0038] During specific implementation, the tension spring 603 is reset to drive the upper sliding block 7 and the lower sliding block 701 to be clamped, so that the placed plate is clamped without affecting the conveying.

[0039] As a preferred structure of this embodiment, Figure 5 As shown, an upper inclined plate 11 with an upward inclined surface is fixedly provided on one side of the upper scraper 6, and the upper air suction hood 4 is above the upper inclined plate 11; a lower inclined plate 1101 with a downward inclined surface is fixedly provided on one side of the lower scraper 604, and the lower air suction hood 401 is below the lower inclined plate 1101.

[0040] The upper inclined plate 11 and the lower inclined plate 1101 are composed of inclined blocks, which can increase the scraping ability of the upper scraper 6 and the lower scraper 604 on the cold rolling oil on the plate, thereby increasing the collection and treatment effect of the cold rolling oil.

[0041] In addition, if Figure 1 and Figure 2 As shown, a bottom groove 101 is provided on the inner bottom surface of the shell 1, which can collect the fallen cold rolling oil, facilitating subsequent collection and processing.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
