Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, and in particular to a shot blasting machine with automatic feeding capability. Background Technology

[0002] Shot blasting is a surface treatment device that uses a high-speed rotating impeller to propel metal shot (such as steel shot, wire cut shot, etc.) at a speed of 60-100 meters per second onto the surface of a workpiece. Through shot impact, it achieves processes such as rust removal, oxide scale removal, strengthening, stress relief, and surface roughening. It features high processing efficiency, good environmental performance (equipped with a dust removal system), and wide applicability (it can process castings, steel structures, automotive parts, etc.). It is widely used in casting, shipbuilding, automobile manufacturing, and other fields. Products treated by shot blasting need to be unloaded by automatic feeding equipment. Currently, most material feeding methods rely on manual feeding by workers. A few feeding devices require a separate power source. The feeding speed and the output speed of the shot blasting machine are difficult to match, making it impossible to achieve timely and efficient feeding. Frequent manual adjustments are required, which is time-consuming and labor-intensive, greatly increasing labor costs and compromising feeding efficiency. Furthermore, the shot blasting machine has a large blasting power, which can easily damage the baffle and cause shot to eject and injure people. Traditional equipment cannot detect this in a timely manner and requires manual inspection, which compromises worker safety and is detrimental to safe production requirements. Utility Model Content

[0013] Reference Figures 1-4 An automatic shot blasting machine includes a housing 1 and an outer shell 2 fixedly connected to the upper side of the housing 1. A feeding platform 3 is fixedly connected to one side of the housing 1, and multiple baffles 5 are fixedly installed on both sides of the outer shell 2. The baffles 5 are composed of multiple baffles evenly fixedly connected to one side of the outer shell 2. The baffles 5 can prevent shot from ejecting from the outer shell 2, preventing accidental injury to workers and damage to the equipment. Due to the great impact force of shot blasting, prolonged obstruction of shot blasting can easily cause one of the baffles to break. A conveying assembly is fixedly installed on the housing 1, and a shot blasting device 6 is fixedly installed on the outer shell 2. The shot blasting device 6 uses centrifugal force to accelerate the shot. An internal power source drives the impeller to rotate at high speed. Abrasive materials such as steel shot, which are thrown in from the center, are captured by the impeller blades and accelerated along the blades. Finally, they are ejected from the edge of the impeller at extremely high speed, forming a dense shot stream that impacts the surface of the workpiece at high speed, thereby completing the cleaning, strengthening, or finishing process. This is existing technology and will not be described in detail. The housing 1 is also equipped with a shot blasting recovery assembly. The housing 1 is also fixedly equipped with an automatic feeding assembly, which includes multiple feeding rods 26. The housing 1 is fixedly equipped with a boss 12. A second rotating shaft 17 and a third rotating shaft 20 are rotatably connected to the boss 12. A first gear 18 is fixedly connected to the second rotating shaft 17, and a second gear 19 is fixedly connected to the third rotating shaft 20. The first gear 18 and the second gear 19 mesh with each other. The multiple feeding rods 26 are circumferentially fixed to the third rotating shaft 20. The rotation of the feeding rods 26 can timely transport the products on the conveyor chain plate 8 to the feeding table 3. The second rotating shaft 17 is connected to the conveying assembly through a transmission assembly. The boss 12 is rotatably connected to the fourth rotating shaft 22 and the fifth rotating shaft 25. The third rotating shaft 20 and the fourth rotating shaft 22 are connected by the second pulley assembly 21. The fourth rotating shaft 22 and the fifth rotating shaft 25 are connected by the transmission belt 23. The detection head 24 is fixedly installed evenly and equidistantly on the outer side of the transmission belt 23. When the detection head 24 passes through the curtain 5, it can contact each baffle in the curtain 5. The detection head 24 is composed of five core components: probe contact mechanism, elastic body deformation assembly, resistance strain gauge sensor, signal conversion circuit and data processing unit. When the probe on the detection head 24 contacts the baffle, the generated small force will cause the elastic body inside the detection head 24 to deform. The resistance value of the strain gauge attached to it will change accordingly. The measurement circuit converts this resistance change into an electrical signal, so that not only the contact can be detected, but also the magnitude of the contact force can be measured. When multiple detection heads 24 break contact during contact with the curtain 5, an alarm is issued. This is the prior art and will not be described in detail. The shot blasting recovery assembly includes a pipe 7 fixedly connected to one side of the shot blaster 6, a blower 10 installed on the pipe 7, a shot blasting port 9 fixedly connected to the inner wall of the housing 2, and a recovery port 11 fixedly connected to one side of the housing 1 for continuous shot recovery. With the power provided by the blower 10, the shot is transported back to the shot blaster 6 through the pipe 7 for re-blasting. The recovery port 11 and the pipe 7 are fixedly connected. The conveying assembly includes a motor 4 fixedly connected to one side of the housing 1, a drive shaft and a driven shaft rotatably connected to the upper side of the housing 1, the drive shaft and the output end of the motor 4 are fixedly connected, and one side of the driven shaft passes through the housing 1 and is fixedly connected to the first bevel gear 13. A transmission chain plate 8 is connected between the drive shaft and the driven shaft.

[0014] When the shot blasting machine is working, the motor 4, shot blaster 6 and blower 10 are started. The motor 4 drives the drive shaft to rotate. The drive shaft and driven shaft drive the conveyor chain plate 8 to transmit the product and transport the product to the area of ​​the shell 2. The shot blaster 6 accelerates the shot and throws it at the product through the shot blasting port 9 to process the product. After the shot is thrown out, it falls into the recovery port 11 on the shell 1. The blower 10 transports the shot in the recovery port 11 to the shot blaster 6 through the pipe 7, and then the shot blaster 6 performs shot blasting again.

[0015] In this invention, when the output products of the shot blasting machine need to be unloaded, the motor 4 drives the drive shaft to rotate, the drive shaft drives the conveyor chain plate 8 to transmit the products, the conveyor chain plate 8 drives the driven shaft to rotate, the driven shaft simultaneously drives the first bevel gear 13 to rotate, the first bevel gear 13 drives the second bevel gear 14 to rotate, the second bevel gear 14 drives the first rotating shaft 15 to rotate, the first rotating shaft 15 drives the second rotating shaft 17 to rotate through the first pulley assembly 16, the second rotating shaft 17 drives the first gear 18 to rotate, the first gear 18 drives the second gear 19 to rotate, the second gear 19 drives the third rotating shaft 20 to rotate, the third rotating shaft 20 drives the unloading rod 26 to rotate, the unloading rod 26 rotates and pushes the products on the conveyor chain plate 8 to the unloading table 3, completing the unloading process. At the same time, the third rotating shaft 20 drives the fourth rotating shaft 22 to rotate through the second pulley assembly 21, the fourth rotating shaft 22 drives the transmission belt 23 to rotate, the transmission belt 23 drives the detection head 24 to move and touch the curtain 5 to detect whether the curtain 5 is intact.
