Driven by the conveying mechanism, the workpiece passes through several (generally one to six) main bodies of the sand blasting machine, and each main body has two upper and lower shot blasting machines to perform mechanical sand blasting on the steel plate to achieve the purpose of surface treatment. The main body is equipped with a dust collector to deal with the dust generated by sand blasting. During the whole operation process, the workpiece on the conveying mechanism is placed horizontally, and the shot blaster blasts sand on the upper and lower surfaces of the workpiece respectively. There are two disadvantages hereby: one, the accumulation of the steel grit that hits the workpiece earlier in the process of sand blasting in this road has a bad influence on the sand blasting effect of this road; , a layer of steel grit accumulates on the upper surface of the workpiece, making the next sandblasting useless. Therefore, it is necessary to configure a high-pressure fan to blow off the steel sand on the surface of the workpiece, but the effect is not very satisfactory, and the air volume generated by the high-pressure fan not only increases the burden on the dust collector but also increases the power consumption.

Detailed ways

Further description will be made below in conjunction with the embodiments of the utility model and the accompanying drawings.

Referring to Fig. 1, Fig. 2, a kind of steel plate blasting machine comprises main conveying frame 10 and main body 20, and main conveying frame 20 has the main roller column 11 and driving motor (not shown in the figure) that are arranged in the same plane, drives The motor drives each roller shaft to rotate through the sprocket chain and transfers the workpiece to be processed (a known technology, so I will not describe it in detail). The main body 20 has a front partition window 21 and a rear partition window 22, and the main body 20 is provided with a shot blasting device 23 and a dust collector (not shown in the figure). The plane where the main roller axis row 11 of the main conveying frame 10 is located forms an inclination angle with the horizontal plane.

The conveyer frame that transports steel plate usually puts steel plate horizontally, in order to change steel plate from horizontal position to oblique position, referring to Fig. 1, Fig. 3, a loading turning frame 30 is configured at the main conveyer frame 10 front ends. The feeding turning frame 30 is provided with a first rocking roller shaft row 31 and an inclined second inclined roller shaft row 32, and a rotating shaft 34 is connected between the feeding turning frame 30 and the first rocking roller shaft row 31 and is connected by a first swinging roller shaft row 31. A pneumatic cylinder 33 drives the first rocking roller shaft row 31 to rotate, the inclination angle of the second skewed roller shaft row 32 is the same as that of the main roller shaft row 11, and the second skewed roller shaft row 32 is positioned below the first rocking roller shaft row 31 and is aligned with the main roller shaft row 11. The main roller row 11 is butted. The motor 35 drives each roller shaft of the second skewed roller row 32 to rotate through the sprocket chain.

Referring to Fig. 1 and Fig. 4, in order to overcome the time it takes for the loading turning frame 30 to change the position of the steel plate, a speed-increasing conveying frame 40 is provided between the second skewed roller row 32 and the main roller row 11. Speed-increasing conveying frame 40 is provided with a 3rd skewed roller shaft row 41, and it is identical with the inclination angle of main roller shaft row 11, and the conveying speed of motor 42 drives the 3rd skewed roller shaft row 41 is greater than main roller shaft row 11, makes front and rear two The separation distance between block workpieces is shortened.

Referring to Fig. 1 and Fig. 5, in order to restore the steel plate after sand blasting from the inclined position to the horizontal position, so as to facilitate the operation of the subsequent conveying process, the main conveyor frame 10 is connected to a blanking turning frame 50 from the rear partition window, and the blanking turning frame 50 is provided with a second rocking roller shaft row 51 and a horizontal roller shaft row 52, and there is a rotating shaft 54 connected between the unloading turning frame 50 and the second rocking roller shaft row 51 and a second air cylinder 53 is used to drive the second rocking roller The shaft row 51 rotates, the horizontal roller shaft row 52 is positioned under the second rocking roller shaft row, and each roller shaft of the horizontal roller shaft row 52 is driven by a motor 55 to rotate through a sprocket chain.

The thrust of each roller shaft to the workpiece depends on the pressure of the workpiece on the roller shaft. The closer the inclination angle is to a right angle, the smaller the pressure will be. Therefore, the inclination angle between the plane where the main roller row 11 is located and the horizontal plane is generally 30 to 75 degrees, and the optimum inclination angle is 60 degrees.

Referring to the accompanying drawings, when the workpiece is horizontally delivered to the first rocking roller column 31 of the feeding turning frame 30 by the feeding mechanism (not included in this case), the electromagnetic valve action is triggered by the limit switch (belonging to the known technology, Not to be described in detail) make the first pneumatic cylinder 33 drive the first swing roller row 31 to rotate and tilt around the rotating shaft 34 until the workpiece slides onto the inclined second roller row 32, and the motor 35 drives the first swing roller row 32 through the sprocket chain. Each roller shaft of the two skewed roller shaft columns 32 rotates, and the conveying workpiece advances forward and continues to enter the speed-increasing conveying frame 40 . After the workpiece breaks away from the first swinging roller row 31, the overturning frame 30 resets and waits for the next round of operation. Since the feeding reversing rack 30 has a resetting, flipping and feeding cycle after sending off a workpiece, there is a gap between the front and rear workpieces, and the speed-increasing conveying frame 40 is provided with a separate motor 42 to drive the third skewed roller shaft row 41 Each roller rotates at a relatively high speed to eliminate the gap between the front and rear workpieces. The workpiece is sent to the main roller axis row 11 of the main conveyor frame 10 in the main body 20 by the third inclined roller row 41 through the front partition window 21, and the workpiece is sanded by a mechanical shot blaster 23. Then, the workpiece is sent out of the main body 20 through the rear partition window 22 to reach the second rocking roller row 51 of the unloading reversing frame 50 . The second pneumatic cylinder 53 drives the second rocking roller column 51 to rotate downwards around the rotating shaft 54, so that the workpiece falls on the horizontal roller column 52, and then the motor 55 drives the rollers of the horizontal roller column 52 through the sprocket chain. The shaft rotates to send the workpiece to the receiving rack (this case does not include it).
