Description

Flat Roller Sandblasting Machine

technical field

The invention relates to a sandblasting machine, in particular to a flat roller sandblasting machine which reduces wear and improves service life.

Background technique

The sandblasting machine can clean the oil and scale on the surface of the brake pad workpiece, and make the surface have a certain roughness to improve the adhesion of the coating film. The traditional sandblasting machine is generally transported by a belt. During the use of the belt, the sand is directly sprayed on the belt. The belt will be severely worn after long-term operation, resulting in loosening of the belt. It is necessary to adjust the tension of the belt frequently. After the belt is worn, the dust will directly contact with the belt. The sand is mixed together, resulting in different surface effects after sandblasting. Moreover, if the surface of the conveyor belt is uneven, it is easy for the workpiece to fall and get stuck, and the sand is easily transported to the outside through the belt, which has a high failure rate and pollutes the next area. In addition, when a certain part of the belt is severely worn, the entire belt needs to be replaced, which is not only costly but also troublesome to replace.

Please refer to FIG. 1 and FIG. 2 again, the dust separator 2 is arranged between the bucket elevator 1 and the sand collection bucket 3 . The output end of the bucket elevator 1 is connected to the dust separator 2, and the output end of the dust separator 2 is connected to the sand collection bucket 3, and the dust separator 2 can be removed in the circulation The dust contained in the sandblasting during use can improve the sandblasting effect on the surface of the plate workpiece. The sand collecting bucket 3 communicates with the spray gun 9 through a pipeline and sends sand to the spray gun 9 . The spray gun 9 is arranged in the blast chamber 6 and communicated with the high-pressure air injection system 16 . The spray gun 9 is arranged in the sand blasting chamber 6, and the spray gun 9 is fixed on the swing arm of the swing device 12, so as to increase the range of sand blasting. The swinging device 12 can make the spray gun 9 swing at an angle, and the angle of the spray gun 9 can be adjusted according to the shape of the workpiece, so as to increase the sandblasting area and achieve a good sandblasting effect.

Referring to Fig. 2 again, the blowing chamber 8 is located at the rear end of the sand blowing chamber 6, the blowing gun 7 is arranged in the blowing chamber 8, and the blowing gun 7 and the high-pressure jet The system 16 communicates, and the high-pressure air injection system 16 provides high-pressure airflow for the blow-off gun 7 . Since a certain amount of sand and dust will remain on the surface of the plate workpiece after sandblasting, if it is not removed in time, it will be transferred to the outside along with the plate workpiece and pollute other areas. Therefore, by setting the blowing chamber 8 and The blowing gun 7 utilizes the high-pressure airflow ejected by the blowing gun 7 to remove the sand grains and dust on the surface of the plate workpiece, which can ensure that the plate workpiece is clean when it is conveyed out. The dust sweeping device 15 is arranged between the blowing chamber 8 and the sand blowing chamber 6, and is located above the conveying chain; the dust sweeping device 15 has a plurality of brushes, and when the plate workpiece passes, The brushes of the dust-sweeping device 15 can pre-sweep the large-volume sand and dust on the surface of the plate workpiece, so as to ensure a better subsequent blow-off effect.

The device 10 is transferred to the transverse spiral sand twisting device 11 at the input end of the bucket elevator 1 . Sandblasting and dust fall from the sand blowing chamber 6 and the cleaning chamber 8 to the longitudinal spiral sand twisting device 10 respectively, and return to The input end of the bucket elevator 1.

Based on the above, the working process of the flat roller sandblasting machine 100100 of the present invention is described in detail below, as follows:

Before sandblasting, the plate workpiece is placed on the surface of the roller 4, the driving device 5 drives the roller 4 to rotate, and then the plate workpiece is translated forward; at the same time, the bucket elevator 1 puts the sand Lifting up, the sand falls into the sand collection bucket 3 through the sand dust separator 2, and the sand collection bucket 3 transports the sand to the spray gun 9 through a pipeline. When the plate workpiece enters the blasting chamber 6, the high-pressure air injection system 16 supplies air to the spray gun 9, so that the spray gun 9 blasts sand on the surface of the plate workpiece. The rollers 4 rotate continuously so that the plate workpieces that have not been sandblasted enter the sand blasting chamber 6 and the plate workpieces that have been sandblasted leave the sand blasting chamber 6 . When the sandblasted plate workpiece passes through the dust sweeping device 15, the dust sweeping device 15 cleans the sand and dust on its surface. After cleaning, the plate workpiece enters the blowing chamber 8, and the high-pressure jet The system 16 supplies air to the blowing gun 7, and the blowing gun 7 blows airflow to the surface of the plate workpiece to blow away the dust attached to the surface of the plate workpiece. The air is extracted and sent to the dust collector 14 for dust removal. After the plate workpiece is blown clean, the drive of the roller 4 comes to the unloading area for unloading. In addition, the sand blown out in the sand blowing chamber 6 will fall on the longitudinal spiral sand twisting device 10, and the longitudinal spiral sand twisting device 10 twists the sand into the horizontal spiral sand twisting device 11, so The horizontal spiral sand twisting device 11 twists the sand to the input end of the bucket elevator 1 for recycling.

Compared with the prior art, because the present invention arranges the rollers 4, the rollers 4 are arranged side by side to form a conveying chain, and the driving device 5 is used to drive the rollers 4, so that the rollers 4 drive the plate workpiece Translate forward to realize the conveyance of sheet metal workpieces and ensure the continuous operation of sheet metal workpieces. When sandblasting, the ejected sand will directly drop from between the two rollers 4 into the spiral twisting sand system below, which greatly reduces the impact of the sand on the rollers 4 and causes serious wear on the rollers 4. , effectively improve the service life. And when a roller 4 wears out, only a single roller 4 needs to be replaced directly, the maintenance cost is low, the installation and disassembly are simple, and the use is convenient. In addition, by setting the spiral twisting sand system and the bucket elevator 1, the ejected sand can be recovered and reused in time, realizing the purpose of automatic cycle sandblasting, effectively reducing labor intensity and improving production efficiency.

The above disclosures are only preferred examples of the present invention, and of course cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the patent scope of the present invention still fall within the scope of the present invention.
