Description

Technical Field

[0001] The utility model relates to the technical field of shot blasting for surface treatment of grooved pipe fittings. More specifically, it relates to a shot blasting device for surface treatment of grooved pipe fittings. Background Technique

[0002] In the existing production technology of grooved pipe fittings, oxides, rust, burrs and other surface defects may appear on the surface of the pipe fittings. If these surface defects are not treated, they will bring many adverse effects. Oxides and rust will reduce the corrosion resistance of the pipe fittings and affect the service life of the pipe fittings. Burrs and other surface defects will affect the appearance quality of the pipe fittings and the aesthetics of the pipe fittings. In addition, surface defects may also affect the coating adhesion of the pipe fittings, making the coating easy to fall off and further affecting the use performance of the pipe fittings.

[0003] To solve these problems, in the prior art, a motor is usually used to drive the shot blasting machine to operate, so as to perform shot blasting processing on the surface of the grooved pipe fittings. Shot blasting processing is a process of removing oxides, rust, burrs and other surface defects by high-speed shot impacting the surface of an object. However, the connection method between the motor and the impeller in the prior art is usually relatively simple. This simple connection method is prone to cause the motor to be overloaded or the connection between the motor and the impeller to break when the motor speed is too fast or the impeller rotation encounters a large resistance. This situation will seriously affect the continuity and stability of the shot blasting processing, and may even lead to equipment damage and safety accidents.

[0004] In addition, some devices in the prior art can also achieve overload protection, but their structures are usually relatively simple. This simple overload protection device cannot flexibly adjust the trigger mechanism of the overload protection device according to actual needs. This inflexible overload protection device may be triggered when protection is not needed, resulting in equipment shutdown and affecting production efficiency. Or, when protection is needed, the overload protection device fails to be triggered in time, resulting in the breakage of the connection between the motor and the impeller, bringing adverse effects.

[0018] 1. The design of the shot blasting device, including components such as the first motor, chain, sprocket, crawler belt, and transmission roller, realizes the full - range shot blasting treatment of the surface of the grooved pipe fittings.

[0031] A buffer bin 19 is arranged above the machine base 1, a conveying pipe 20 is arranged outside the buffer bin 19, and the output end of the buffer bin 19 is connected to the input end of the shot blasting machine 2 through the conveying pipe 20.

[0032] A conveyor 21 is arranged on one side of the machine base 1, a filter 22 is arranged on one side of the conveyor 21, the output end of the conveyor 21 is connected to the input end of the filter 22 through the conveying pipe 20, and the output end of the filter 22 is connected to the input end of the buffer bin 19 through the conveying pipe 20.

[0033] A limiting groove 23 is opened on the side wall of the movable groove 10, limiting blocks 24 are arranged on the outer sides of the adjusting block 15 and the trigger block 5, and the limiting blocks 24 are slidably installed in the limiting groove 23.

[0034] In this embodiment, before the device needs to be used, first rotate the rotating sleeve 12 in the corresponding direction according to the usage requirements. The rotating sleeve 12 will drive the internal gear 16 arranged inside to rotate. Then the internal gear 16 will drive each external gear 17 to rotate, thereby driving the lead screw 18 to rotate. Since the lead screw 18 and the sliding block 13 are movably connected by threads, when the lead screw 18 rotates, the sliding block 13 drives the adjusting block 15 to move along the sliding groove 14. At the same time, the adjusting block 15 will drive the limiting blocks 24 arranged on both sides to slide along the limiting groove 23, so that the distance between the adjusting block 15 and the trigger block 5 changes. Then the pressure exerted by the spring 6 on the trigger frame 4 through the trigger block 5 will change, thereby achieving the purpose of adjusting the triggering mechanism of the protection device. After adjustment, stop rotating the rotating sleeve 12. When the speed of the second motor 3 is too fast or the impeller arranged in the shot blasting machine 2 encounters too much resistance, the side wall of the trigger groove 8 opened on the outer side of the connecting shaft 7 will squeeze the side wall of the trigger rod 9. Due to the rounded corner structure design of the side wall of the trigger groove 8 and one end of the trigger rod 9, the trigger rod 9 will gradually disengage from the trigger groove 8. At the same time, the trigger rod 9 will drive the trigger frame 4 to squeeze the trigger block 5. Due to the special structure design of the trigger block 5 and the trigger frame 4, the trigger block 5 will slide to one side and cooperate with the adjusting block 15 to squeeze the spring 6. Then one end of the trigger rod 9 will completely disengage from the trigger groove 8, causing the second motor 3 to rotate idly, avoiding the occurrence of overload phenomenon. Then the staff has sufficient time to make a reasonable judgment and take corresponding measures.

[0035] Please refer to Figure 1 and Figure 3 , as an embodiment of the shot blasting device: The shot blasting device includes a first motor 25, a chain 26, a sprocket 27, a crawler 28 and a transmission roller 29. The first motor 25 is installed above the machine base 1. The sprockets 27 are respectively installed at one end of the corresponding transmission roller 29 and the output end of the first motor 25. The chain 26 is sleeved outside the sprockets 27. A plurality of transmission rollers 29 are movably arranged in the machine base 1. The crawler 28 is sleeved outside the transmission rollers 29.

[0036] Anti-slip blocks 30 are arranged on the outer side of the crawler 28, and the anti-slip blocks 30 are fixedly connected to the outer side of the crawler 28.

[0037] A limiting ring 31 is arranged inside the machine base 1, and the limiting ring 31 is movably connected to the crawler 28.

[0038] Engaging grooves 32 are opened on the outer side of the transmission roller 29, and engaging blocks 33 are arranged on the inner side of the crawler 28. The engaging blocks 33 are adapted to the engaging grooves 32.

[0039] More specifically, when it is necessary to use this device to perform shot peening on the surface of grooved pipe fittings, first connect the conveyor 21 to an external storage device, and then convey the shot through the conveying pipe 20 to the filter 22 for filtration. After filtration, the shot that meets the specifications will be conveyed through the conveying pipe 20 connected to the output end of the filter 22 to the buffer bin 19, and then conveyed through the conveying pipe 20 connected to the output end of the buffer bin 19 to each shot peening machine 2. Then turn on the second motor 3, and the second motor 3 drives the shot peening machine 2 to operate to eject the shot into the machine base 1. At the same time, pass the grooved pipe fitting through one of the limit rings 31 and place it on the crawler 28 arranged in the machine base 1. Then turn on the first motor 25, and the first motor 25 drives the chain 26 sleeved on the outside through the sprocket 27 arranged at the output end to rotate. Then the chain 26 drives the sprocket 27 arranged on one side of the corresponding transmission roller 29 to rotate. Then the sprocket 27 here drives the transmission roller 29 to rotate. Then the transmission roller 29 here drives the crawler 28 to operate through the cooperation of the engaging groove 32 and the engaging block 33. The setting of the anti-slip block 30 improves the anti-slip ability of the surface of the crawler 28, so as to promote the rotation of the grooved pipe fitting on the crawler 28, and thus realize the all-round surface treatment processing.

[0040] In summary, when the overall device is in use or operation: before using this device, first rotate the rotating sleeve 12 in the corresponding direction according to the use requirements. The rotating sleeve 12 drives the internal gear 16 arranged inside to rotate, and then the internal gear 16 drives each external gear 17 to rotate, thereby driving the lead screw 18 to rotate. Since the lead screw 18 and the sliding block 13 are movably connected by threads, when the lead screw 18 rotates, the sliding block 13 drives the adjusting block 15 to move along the sliding groove 14. At the same time, the adjusting block 15 drives the limit blocks 24 arranged on both sides to slide along the limit groove 23, so that the distance between the adjusting block 15 and the trigger block 5 changes. Then the pressure exerted by the spring 6 on the trigger frame 4 through the trigger block 5 will change, so as to achieve the purpose of adjusting the trigger mechanism of the protection device. After adjustment, stop rotating the rotating sleeve 12. When the rotational speed of the second motor 3 is too fast or the impeller arranged in the shot peening machine 2 encounters too much resistance, the side wall of the trigger groove 8 opened on the outside of the connecting shaft 7 will squeeze the side wall of the trigger rod 9. Due to the rounded corner structure design of the side wall of the trigger groove 8 and one end of the trigger rod 9, the trigger rod 9 will gradually disengage from the trigger groove 8. At the same time, the trigger rod 9 drives the trigger frame 4 to squeeze the trigger block 5. Due to the special structure design of the trigger block 5 and the trigger frame 4, the trigger block 5 will slide to one side and cooperate with the adjusting block 15 to squeeze the spring 6. Then one end of the trigger rod 9 will completely disengage from the trigger groove 8, causing the second motor 3 to run idle, avoiding the occurrence of overload phenomenon, and then the staff has sufficient time to make a reasonable judgment and response.

[0041] When the device is needed to perform shot blasting on the surface of the grooved pipe, the conveyor 21 is first connected to the storage device of the external device, and then the shot is conveyed to the filter 22 through the conveying pipe 20 for filtering. After filtering, the shot that meets the specifications will be conveyed to the buffer bin 19 through the conveying pipe 20 connected to the output end of the filter 22, and then conveyed to each shot blasting machine 2 through the conveying pipe 20 connected to the output end of the buffer bin 19. Then, the second motor 3 is turned on, and the second motor 3 drives the shot blasting machine 2 to operate and eject the shot into the machine base 1, and at the same time, the grooved pipe is placed on the machine base 1 through one of the limit rings 31. The first motor 25 is turned on the crawler 28 arranged inside, and then the first motor 25 drives the chain 26 arranged on the outside to operate through the sprocket 27 arranged at the output end, and then the chain 26 drives the sprocket 27 arranged on the side of the corresponding transmission roller 29 to rotate, and then the sprocket 27 here drives the transmission roller 29 to rotate, and then the transmission roller 29 here drives the crawler 28 to run through the cooperation of the engaging groove 32 and the engaging block 33. The setting of the anti-slip block 30 improves the anti-skid ability of the surface of the crawler 28, thereby prompting the groove pipe to rotate on the crawler 28, thereby realizing all-round surface treatment processing.

[0042] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded.
