Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment, and in particular to an automatic shot screening and separation device for shot blasting machines. Background Technology

[0002] A shot blasting machine is a mechanical device that uses high-speed projectiles (such as steel shot, cast iron shot, etc.) to treat the surface of workpieces. It is mainly used for cleaning, strengthening, surface treatment and other processes.

[0003] In the practical application of shot blasting machines, the recycling of shot is a crucial step. Currently, most existing shot blasting machines are equipped with internal circulation systems. However, during long-term use, the shot will wear down. Excessively worn shot will become smaller, and continued use will adversely affect the processing quality of the workpiece. Furthermore, dust and impurities will adhere to the surface of the shot. If these impurities are not removed, they will remain on the workpiece surface, thus affecting the shot blasting process. Therefore, an automatic shot screening and separation device for shot blasting machines is needed. Utility Model Content

[0004] The main objective of this invention is to provide an automatic shot screening and separation device for shot blasting machines, which can effectively solve the problems mentioned above.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An automatic shot screening and separation device for shot blasting machines includes an outer cylinder, a discharge port fixedly connected to the front inclined surface of the outer cylinder, a feed port fixedly connected to the rear inclined surface of the outer cylinder, a slag discharge port fixedly connected to the lower middle side of the outer surface of the outer cylinder, a drive assembly fixedly installed on the upper side of the front inclined surface of the outer cylinder, a screening assembly jointly installed on the outer surfaces of the discharge port and the feed port, and a cleaning device fixedly installed on the upper rear side of the outer surface of the outer cylinder.

[0007] Preferably, the screening assembly includes a screening cylinder, which is rotatably connected to a portion of the outer surface of the discharge port and the inlet port that are close to each other. The outer surface of the screening cylinder has a plurality of sieve holes. The left and right sides of the front and rear sides of the inner surface of the screening cylinder are fixedly connected to fixing strips. The two fixing strips on the left and right sides that are close to each other are fixedly connected to a fixing rod. The upper and lower sides of the outer surface of the fixing rod are fixedly connected to three baffles. The front ends of the six baffles are each provided with a plurality of circular holes.

[0008] Preferably, the drive assembly includes a servo motor, which is fixedly connected to the upper side of the front inclined surface of the outer cylinder. A transmission rod is fixedly connected to the output end of the servo motor. A spur gear is fixedly connected to both the front and rear of the outer surface of the transmission rod. A gear ring is fixedly connected to both the front and rear of the outer surface of the screening cylinder.

[0009] Preferably, the spur gear and the ring gear located on the same side mesh with each other.

[0010] Preferably, the transmission rod is rotatably connected to the middle of the upper side of the front and rear walls of the outer cylinder.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This device, through its designed drive and screening components, uses the drive component to rotate the screening cylinder, causing the steel shot to sway inside the cylinder. The screen holes separate excessively worn and smaller steel shot, ensuring that all steel shot entering the shot blasting machine is qualified. The device is installed at an angle, allowing the steel shot to slide forward while swaying inside the screening cylinder, achieving continuous screening and separation of steel shot during the circulation process and improving work efficiency.

[0015] 2. Through its designed cleaning device, this device can suck up the dust and impurities that are shaken off the surface of the steel shot during the screening process and transport them to the water tank to mix with clean water. This achieves dust collection, avoids impurities remaining on the surface of the workpiece, and improves the effect of the shot blasting process. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Example 1, as Figure 1 and Figure 2 As shown, an automatic shot screening and separation device for shot blasting machines includes an outer cylinder 1. A discharge port 3 is fixedly connected to the front inclined surface of the outer cylinder 1, and a feed port 6 is fixedly connected to the rear inclined surface of the outer cylinder 1. A slag discharge port 4 is fixedly connected to the lower middle side of the outer surface of the outer cylinder 1. A drive assembly 2 is fixedly installed on the upper side of the front inclined surface of the outer cylinder 1. A screening assembly 7 is installed on the outer surfaces of the discharge port 3 and the feed port 6. A cleaning device 5 is fixedly installed on the upper rear side of the outer surface of the outer cylinder 1.

[0024] Before implementing this device, firstly:

[0025] Existing shot blasting machines are all equipped with an internal circulation system to recover and reuse the blasted steel shot;

[0026] Therefore, this device can be installed at an angle on the upper part of the shot blasting machine. Then, the discharge port 3 is connected to the feed port of the shot blasting machine, and the feed port is connected to the discharge port of the internal circulation system. This device is installed between the feed port of the shot blasting machine and the discharge port of the internal circulation system. Then, the operator injects clean water into the cleaning device 5 and installs a collection bag or collection box at the lower part of the slag discharge port 4. The device can then be used for operation.

[0027] In the above process, when the internal circulation system of the shot blasting machine delivers steel shot to the feed inlet 6, it enters the screening component 7 through the feed inlet 6. At this time, the operator needs to start the drive component 2 to rotate the screening component 7. When the screening component 7 rotates, it will cause the fed steel shot to shake. At this time, the excessively worn and smaller steel shot in the fed steel shot will be separated and fall from the screening component 7 into the outer cylinder 1, and then fall from the slag outlet 4 into the placed collection bag for centralized collection.

[0028] As described above, due to the oblique installation design of the device, the steel shot will slide forward while shaking in the screening component 7 and fall into the shot blasting machine through the discharge port 3. This achieves the screening and separation of steel shot during the internal circulation process, enabling the shot blasting machine to ensure the quality of workpiece processing.

[0029] In the above process, when the steel shot is in the screening component 7, the screening component 7 impacts the steel shot, shaking off the dust and impurities on the surface of the steel shot. At this time, the operator starts the cleaning device 5 to absorb the dust that has been shaken off and transport it into the injected clean water, so that the dust and clean water are mixed to collect the dust and ensure that the surface of the steel shot is clean.

[0030] In the second embodiment, the drive assembly 2 further includes a servo motor 21, which is fixedly connected to the upper side of the front inclined surface of the outer cylinder 1. A transmission rod 23 is fixedly connected to the output end of the servo motor 21. A spur gear 24 is fixedly connected to both the front and rear of the outer surface of the transmission rod 23. A gear ring 22 is fixedly connected to both the front and rear of the outer surface of the screening cylinder 71.

[0031] Furthermore, the spur gear 24 and the gear ring 22 located on the same side mesh with each other;

[0032] Furthermore, the transmission rod 23 is rotatably connected to the upper middle part of the front and rear walls of the outer cylinder 1.

[0033] In the above process, the operator starts the servo motor 21 to make the output end of the servo motor 21 rotate. When the output end of the servo motor 21 rotates, it drives the transmission rod 23 to rotate through the coupling. The transmission rod 23 drives the spur gear 24 to rotate. When the spur gear 24 rotates, it transmits power to the gear ring 22 through meshing with the gear ring 22, causing the gear ring 22 to rotate. When the gear ring 22 rotates, it drives the screening component 7 to rotate together, so that the screening component 7 can screen and separate the steel shot, separating the steel shot that has been worn too much and has become smaller in size.

[0034] Furthermore, in order to achieve the purpose of screening and separating steel shot by screening component 7, see [reference needed]. Figure 3 and Figure 4 The screening component 7 includes a screening cylinder 71, which is rotatably connected to a portion of the outer surface of the discharge port 3 and the inlet port 6 that are close to each other. The outer surface of the screening cylinder 71 has a number of screen holes 72. The left and right sides of the front and rear sides of the inner surface of the screening cylinder 71 are fixedly connected to fixing strips 73. The two fixing strips 73 located on the left and right sides are fixedly connected to a fixing rod 74 at their close ends. The upper and lower sides of the outer surface of the fixing rod 74 are fixedly connected to three baffles 75. The front ends of the six baffles 75 are each provided with a number of circular holes 76.

[0035] In the above process, the drive assembly 2 drives the screening cylinder 71 to rotate. When the steel shot enters the screening cylinder 71 through the feed port 6, the rotation of the screening cylinder 71 will cause the steel shot to shake inside. At this time, the sieve holes 72 on the outer surface of the screening cylinder 71 will separate the excessively worn steel shot to the outside, while the qualified steel shot will slide to the front of the screening cylinder 71 and then into the discharge port 3. After that, it will enter the shot blasting machine through the discharge port 3 to complete the screening and separation.

[0036] In the above process, when the steel shot shakes inside the screening cylinder 71, it will collide with the baffle 75, causing the steel shot to vibrate and dislodging the dust from its outer surface. The dust is then collected by the cleaning device 5 to keep the surface of the steel shot clean and prevent impurities from remaining on the surface of the workpiece.

[0037] Furthermore, in order to achieve the purpose of collecting dust and impurities under vibration by the cleaning device 5, see [reference needed]. Figure 5 The cleaning device 5 includes an air pump 52, which is fixedly connected to the upper rear side of the outer surface of the outer cylinder 1. An air suction pipe 51 is fixedly connected to the input end of the air pump 52, and an air delivery pipe 53 is fixedly connected to the output end of the air pump 52. A water tank 55 is fixedly connected to the upper side of the rear inclined surface of the outer cylinder 1. A water injection valve 54 is fixedly connected to the rear side of the upper inclined surface of the water tank 55, and a water outlet valve 56 is fixedly connected to the lower middle side of the right end of the water tank 55.

[0038] Furthermore, the outlet of the air supply pipe 53 penetrates the middle side of the upper inclined surface of the water tank 55 and extends into the interior, while the air intake pipe 51 is connected to the outer cylinder 1.

[0039] In the above process, the staff injects clean water into the water tank 55 through the water injection valve 54, and then starts the air pump 52 to operate. The air pump 52 draws air into the outer cylinder 1 through the air suction pipe 51, sucking the dust that has been shaken down into the air pump 52. The air pump 52 then delivers the sucked air into the air delivery pipe 53, and then delivers the air and dust into the water tank 55 through the air outlet of the air delivery pipe 53, so that the dust mixes with the dust in the water tank 55, thus completing the dust collection.

[0040] In the above process, air flows out to the outside through the water injection valve 54. When it is necessary to replace the clean water in the water tank 55, the staff only needs to open the water outlet valve 56 to release the wastewater in the water tank 55, then close the water outlet valve 56, and refill the water tank 55 with water through the water injection valve 54 to complete the replacement.

[0041] When cleaning is required, simply keep the water outlet valve 56 open and continuously inject water into the water tank 55 to complete the rinsing and keep the water tank 55 clean.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
