[0046] Shot blasting machine and shot blasting mechanism

[0047] In this embodiment, a shot blasting machine body 1 and a shot blasting mechanism 2 in the prior art are proposed. The shot blasting machine body 1 has a channel for the workpiece to pass through. A conveying mechanism 100 is installed in the channel. The conveying mechanism 100 can be a conventional conveying roller or conveyor belt, and also has a conventional control system. The shot blasting mechanism 2 can be a conventional shot blasting wheel. The shot blasting nozzle is installed on the shot blasting wheel, which is driven by a motor to rotate at a high speed to generate centrifugal force, and the shot blasting agent is sprayed onto the surface of the workpiece through the shot blasting nozzle 20. The workpiece is placed on the conveying mechanism 100 of the shot blasting machine, and then enters the channel through the conveying mechanism 100. At the same time, the shot blasting mechanism 2 is operated to spray the shot blasting agent onto the surface of the workpiece, and the surface impurities are removed by the high-speed collision and friction. The cleaned workpiece is then moved out of the shot blasting machine through the conveying mechanism 100 to complete the entire cleaning process.

[0049] The shot blasting agent baffle plate 3 is arranged below the shot blasting nozzle 20; the shot blasting agent acceleration belt 4 is arranged on the right side of the shot blasting agent baffle plate 3; a shot blasting output channel is formed between the shot blasting agent baffle plate 3 and the shot blasting agent acceleration belt 4, the shot blasting agent acceleration belt 4 is driven by a roller and a motor, and the surface of the shot blasting agent acceleration belt 4 is provided with anti-skid particles, the shot blasting agent baffle plate 3 is an elastic baffle plate, the shot blasting agent baffle plate 3 and the shot blasting agent acceleration belt 4 are parallel to each other, the rollers have at least two and are distributed up and down, the shot blasting agent acceleration belt 4 is sleeved on two rollers, and the motor is connected to one of them. A roller is connected to drive it to rotate. After being output by the shot blasting nozzle, the shot blasting agent enters the channel between the shot blasting agent baffle 3 and the shot blasting agent acceleration belt 4. At this time, the shot blasting agent contacts the shot blasting agent baffle 3 and the shot blasting agent acceleration belt 4, so that the initial velocity and rotation speed of the shot blasting agent are further increased under the action of the shot blasting agent acceleration belt 4, and the shot blasting agent is sprayed onto the surface of the workpiece, and the surface impurities are removed by the high-speed collision and friction. The cleaned workpiece is then moved out of the shot blasting machine through the conveying mechanism 100, completing the entire cleaning process.

[0050] Shot blasting recovery system

[0051] The shot blasting recovery system further includes: a recovery trough 5, which is arranged in the shot blasting machine body 1 and is located below the shot blasting nozzle 20, the recovery trough 5 is bucket-shaped, and a shot blasting agent leakage hole 50 is arranged at the bottom of the recovery trough 5; a recovery chamber 6, which is arranged in the shot blasting machine body 1 and is located below the recovery trough 5; a shot blasting screening mechanism 7, which is arranged in the recovery chamber 6 for screening the worn shot blasting agent; a shot blasting recovery mechanism 8, which is arranged in the recovery chamber 6 for recovering the shot blasting agent screened by the shot blasting screening mechanism 7; wherein the shot blasting agent leakage hole 50 is connected to the recovery chamber 6, and the shot blasting recovery mechanism 8 can transport the recovered shot blasting to the shot blasting mechanism 2;

[0052] The shot recovery mechanism 8 proposed in this embodiment is an existing mechanism, which usually includes a box, a screw conveyor and a lifting device. The shot blasting agent enters the box after passing through the shot blasting screening mechanism 7, and returns to the shot blasting mechanism 2 through the screw conveyor and the lifting device for recycling;

[0053] The recovery groove 5 is located in the shot blasting agent body and the recovery groove 5 is located at the bottom of the channel in the shot blasting machine body 1. The right side slope of the recovery groove 5 can extend toward the discharge port and be close to the discharge port. The outer surface of the shot blasting machine body 1 can be installed with a maintenance door to facilitate opening the recovery chamber 6 to inspect the device inside the recovery chamber 6.

[0054] The shot blasting screening mechanism also includes: a collecting box 70, in which an inclined sieve plate 71 is arranged, support plates 72 are arranged on both sides of the collecting box 70, a discharge port is arranged on the side wall of the collecting box 70 close to the discharge port, a sewage discharge port is arranged at the bottom of the collecting box 70, and an electric door 73 is arranged on the discharge port; the electric door 73 is a conventional existing structure, a guide plate 74, and the guide plate 74 has two pieces, and the two guide plates 74 are respectively arranged on the shot blasting agent leakage hole 50 and the discharge port; a support member 75, the support member 75 is arranged on both sides of the collecting box 70, and the support member 75 is connected to the support plate 72 for supporting the collecting box 70; an extrusion member 76, which is arranged in the shot blasting machine body 1 and is located above the support plate 72;

[0055] The support member 75 can drive the collection box 70 to vibrate after being squeezed by the squeezing member 76 .

[0056] After cleaning the surface of the workpiece, the shot blasting agent falls downward into the recovery groove 5 and moves along the recovery groove 5 to the shot blasting agent leakage hole 50, and enters the collection box 70 through the shot blasting agent leakage hole 50 and the guide plate 74. When the shot blasting agent falls into the collection box 70, it contacts the screen plate 71 and is impacted by collision. The impurities and dust attached to the shot blasting agent are separated from the shot blasting agent under the impact of collision. The impurities can fall into the bottom of the collection box 70 through the screen plate 71, and the dust escapes into the recovery chamber 6. At the same time, the worn individuals in the shot blasting agent also fall into the bottom of the collection box 70 through the screen plate 71. After the shot blasting agent is collected on the screen plate 71 for a period of time, the extrusion member 76 squeezes the support plate 72 to squeeze the support member 75. After the extrusion member 76 is released, the support frame can drive the collection box 70 to vibrate, so that the shot blasting agent on the screen plate 71 is repeatedly thrown up and down, and the worn individuals in the shot blasting agent and the impurities and dust attached to the surface of the shot blasting agent are further separated.

[0057] Support

[0058] The support member 75 further includes: a reversing portion 750, which is in the shape of a direct curved tube and has one end extending vertically and the other end extending horizontally, and a pressure chamber 7501 is provided in the reversing portion 750; a support column 751, which is movably provided at the vertically extending end of the reversing portion 750, and the bottom end of the support column 751 is located in the pressure chamber 7501 and is provided with a first piston 7510 which is sealed and matched with the pressure chamber 7501; a linkage column 752, which is movably provided at the horizontally extending end of the reversing portion 750, and the right end of the linkage column 752 is located in the pressure chamber 7501 and is provided with a second piston 7520 which is sealed and matched with the pressure chamber 7501; a first transmission rack 753, which is provided at the left end of the linkage column 752; A first gear set, the first gear set includes a first driving gear 754 and a first driven gear 755; a second gear set, the second gear set includes a second driving gear 756 and a second driven gear 757; a third gear set, the third gear set includes a third driving gear 758 and a third driven gear 759; a second transmission rack 7511, the second transmission rack 7511 is slidably arranged at the bottom of the recovery chamber 6, and the two ends of the second transmission rack 7511 are provided with a first elastic member 7512; a third transmission rack 7513, the third transmission rack 7513 is slidably arranged at the bottom of the recovery chamber 6, and the two ends of the third transmission rack 7513 are provided with a second elastic member 7514; a torsion spring 7515, the torsion spring 7515 is arranged on one side of the third gear set;

[0059] Among them, the top end of the support column 751 is connected to the support plate 72, the first transmission rack 753 is meshed with the first driving gear 754, the second driving gear 756 is meshed with the first driven gear 755, the third driving gear 758 is meshed with the second driven gear 757, the third driven gear 759 is connected to the torsion spring 7515, the second transmission rack 7511 is meshed with the second driven gear 757, and the third transmission rack 7513 is meshed with the third driven gear 759.

[0060] The second elastic member 7514 and the first elastic member 7512 may be conventional elastic structures such as springs;

[0061] The extrusion member 76 squeezes the support plate 72 to squeeze the support member 75. After the support member 75 is squeezed, the support column 751 moves into the pressure chamber 7501, thereby squeezing the medium in the pressure chamber 7501, driving the linkage column 752 to move horizontally out of the pressure chamber 7501. The first transmission rack 753 moves horizontally due to the movement of the linkage column 752, driving the first gear group meshing with it to operate. With the operation of the first gear group, the second gear group and the third gear group operate at the same time, and the second driven gear 757 and the third driven gear 759 rotate. The second transmission rack 7511 and the third transmission rack 7513 are driven to move during the process. The second transmission rack 7511 moves horizontally so that the first elastic members 7512 on both sides thereof are stretched and contracted respectively. The third transmission rack 7513 moves horizontally so that the second elastic members 7514 on both sides thereof are stretched and contracted respectively. At the same time, the torsion spring 7515 is twisted along with the rotation of the third driven gear 759. When the extrusion member 76 is released, the first elastic member 7512, the second elastic member 7514 and the torsion spring 7515 can quickly drive the first gear group, The second gear set and the third gear set rotate back and forth, thereby squeezing the pressure chamber 7501 through the linkage column 752 to drive the support column 751 to move back and forth in the vertical direction, so that the collection box 70 vibrates rapidly. At the same time, the first elastic member 7512, the second elastic member 7514 and the torsion spring 7515 work together to effectively increase the reciprocating frequency of the support column 751 and limit its moving stroke, thereby increasing the vibration frequency of the collection box 70 and limiting the vibration amplitude of the collection box 70, reducing the installation space required for the collection box 70, and the shot blasting agent on the sieve plate 71. It can surge with rapid vibration and be continuously impacted by collision, which effectively improves the screening effect of worn shot blasting agent and effectively separates impurity dust attached to the shot blasting agent. In addition, since the shot blasting machine itself has ample space in the length direction, the vertical vibration can be converted into horizontal vibration through the setting of the reversing part 750, thereby ensuring the elastic force required for the vibration of the collection box 70 and reducing the space required for the support column 751 in the vertical direction, ensuring the normal size of the shot blasting machine body 1, and facilitating the placement of the shot blasting machine and the shot blasting operation.

[0064] The limiting ball 768 can cooperate with the limiting segment 764 to limit the movement of the push rod 763 , and the limiting ball 768 can fall into the ball groove 769 and release the cooperation with the limiting segment 764 after the outer rod 761 moves downward.

[0065] When the extrusion piece 76 extrudes the support plate 72, the driving cylinder 760 drives the outer rod 761 to move toward the support plate 72. As the outer rod 761 moves to the support plate 72, the bottom end of the inner rod 762 abuts against the surface of the support plate 72. Then the outer rod 761 continues to move so that the inner rod 762 contracts toward the inside of the outer rod 761. At this time, the support plate 72 is initially squeezed to drive the support column 751 to move. As the inner rod 762 continues to move toward the inside of the outer rod 761, the limiting ball 768 cooperates with the limiting segment 764 to squeeze and contract the ejection spring 765. At the same time, the upper spring 766 in the reset spring is also squeezed by the inner rod 762 and contracts. After the limiting ball 768 moves to the ball groove 769, the limiting ball 768 falls into the ball groove 769 and contacts the limiting segment 764. When the fit is released and the limit section 764 loses its restriction, the push-out spring 765 drives the push rod 763 to move outward. Under the action of the push-out spring 765, the push rod 763 extends the inner rod 762 and contacts the support plate 72 to further push the support plate 72. After the push rod 763 is pushed out, the driving cylinder 760 quickly retracts and drives the outer rod 761 away from the support plate 72, completing the extrusion of the support member 75. At the same time, under the action of the reset spring, the outer rod 761 and the inner rod 762 are reset to prepare for the next extrusion. The arrangement of the outer rod 761, the inner rod 762 and the push rod 763 can reduce the stroke required for the extrusion member 76 while ensuring the extrusion effect on the support member 75, thereby reducing the space required for the extrusion member 76 in the vertical direction and ensuring the vibration effect of the collection box 70.
