Description

Technical Field

[0001] This utility model relates to the field of sandblasting machine technology, specifically a sandblasting machine with wear-resistant function. Background Technology

[0002] Sandblasting is a process that uses the impact of high-speed abrasive jets to clean and roughen the surface of a substrate. Powered by compressed air, it forms a high-speed jet stream that propels the abrasive material at high speed onto the surface of the workpiece. This causes changes in the outer surface or shape of the workpiece. Due to the impact and cutting action of the abrasive on the workpiece surface, the surface achieves a certain degree of cleanliness and varying roughness, thereby improving the mechanical properties of the workpiece surface.

[0003] According to a public notice (CN110757350B) regarding an environmentally friendly sandblasting machine with anti-clogging function for shipbuilding, the aforementioned application uses a screening mechanism to remove impurities from the abrasive to prevent clogging, thus reducing the likelihood of clogging. Compared to existing screening mechanisms, this mechanism uses a connecting component to ensure close contact between the brush and the screen, improving the cleaning effect of the brush and reducing the likelihood of clogging. However, the brush's oscillation pattern is relatively simple, resulting in a lower cleaning effect and the possibility of screen clogging still exists. To address this issue, we propose a sandblasting machine with wear-resistant properties. Utility Model Content

[0004] The purpose of this invention is to provide a sandblasting machine with wear-resistant function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sandblasting machine with wear-resistant function, comprising a machine tank, the bottom of which is fixedly connected to one end of a connecting pipe, the other end of which is connected to a pump body, the pump body being fixedly connected to one end of a conveying pipe, the other end of which is fixedly connected to a wear-resistant nozzle, a screen plate being fixedly installed on the inner wall of the machine tank, protrusions being fixedly installed on the inner wall of the machine tank, a fixing plate being fixedly installed on the inner wall of the machine tank, and a control component being provided inside the machine tank, the control component including:

[0006] The brush bristles are connected to the support block via a flat plate;

[0007] A fixing block, wherein the fixing block is disposed on the top of the support block;

[0008] The movable component is used to remove impurities from the surface of the screen plate, thereby achieving all-round cleaning of the screen plate, avoiding clogging of the screen holes and affecting the removal of particles inside the abrasive, thus extending the service life of the wear-resistant nozzle and reducing wear factors from the source.

[0009] Preferably, the bristles are fixedly installed at the bottom of the plate, a support block is fixedly installed at the top of the plate, and a fixing block is fixedly installed at the top of the support block. When the cut surface of the fixing block is abutted, the fixing block can be forced to drive the support block and the plate to move laterally within the connecting plate.

[0010] Preferably, the movable component includes a flat rod that passes through the support block and is slidably connected to the support block. The side of the support block is fixedly connected to one end of a spring, and the other end of the spring is fixedly installed on the arc surface of the flat rod. The flat rod ensures the stability of the support block during lateral movement.

[0011] Preferably, the flat rod is fixedly installed on the inner wall of the connecting plate, the top of the connecting plate is in contact with the bottom of the fixing block, and a support rod is fixedly installed on the top of the fixing block. When the cut surface of the fixing block is in contact, the support rod can be driven to slide along the surface of the connecting plate.

[0012] Preferably, a vertical rod is fixedly installed on the top of the connecting plate, the vertical rod passes through the knocking rod and is slidably connected to the knocking rod, and a triangular block is fixedly installed on the side of the knocking rod. When the cut surface of the triangular block is abutted, the triangular block can be forced to drive the knocking rod to move longitudinally along the surface of the vertical rod.

[0013] Preferably, the inner wall of the striking rod is fixedly connected to one end of the second spring, and the other end of the second spring is fixedly installed on the arc surface of the vertical rod. When the striking rod is no longer under force, it can bounce up under the action of the second spring.

[0014] Preferably, the connecting plate is fixedly installed on the arc surface of the rotating rod, the rotating rod passes through the fixed plate and is rotatably connected to the fixed plate, a motor is fixedly installed on the top of the fixed plate, the output shaft of the motor is fixedly connected to the top of the rotating rod, and the output shaft of the motor is driven by force to make the rotating rod and the connecting plate move in a circular motion within the fixed plate.

[0015] Compared with the prior art, this utility model provides a sandblasting machine with wear-resistant function, which has the following beneficial effects:

[0016] 1. This wear-resistant sandblasting machine, equipped with a control component, allows the motor's output shaft to drive a rotating rod, which in turn rotates the connecting plate fixed to the rod's surface. As the connecting plate rotates, the flat plate connected to the support block within the connecting plate drives the brush bristles to move in a circular motion on the screen plate's surface. During rotation, when the protrusion abuts against the tangential surface of the fixed block, the fixed block is forced to move the support block and flat plate laterally within the connecting plate. The brush bristles at the bottom then intermittently rub the screen plate's surface, achieving comprehensive cleaning of the screen plate. This prevents screen hole blockage, which hinders the removal of abrasive particles, thus extending the service life of the wear-resistant nozzle and reducing wear factors at the source.

[0017] 2. This wear-resistant sandblasting machine is equipped with a movable component. When the fixed block moves on the surface of the connecting plate, the support rod fixed to the surface of the fixed block will move towards the triangular block. When the tangent of the triangular block is in contact, it can drive the hammer rod to lift along the surface of the vertical rod. When the tangent of the triangular block is no longer in contact, the hammer rod can be lifted by the action of the second spring, thereby intermittently striking the top of the screen plate, thus accelerating the flow of abrasive and avoiding long-term residence that affects subsequent sandblasting operations.

[0023] like Figures 1-4As shown, this utility model provides a technical solution: a sandblasting machine with wear-resistant function, including a machine tank 1. The bottom of the machine tank 1 is fixedly connected to one end of a connecting pipe 2, and the other end of the connecting pipe 2 is connected to a pump body 3. The pump body 3 is fixedly connected to one end of a conveying pipe 4, and the other end of the conveying pipe 4 is fixedly connected to a wear-resistant nozzle 5. A screen plate 6 is fixedly installed on the inner wall of the machine tank 1, a protrusion 7 is fixedly installed on the inner wall of the machine tank 1, and a fixing plate 8 is fixedly installed on the inner wall of the machine tank 1. A control component 9 is provided inside the machine tank 1, and the control component 9 includes: brush bristles 91, a flat plate 92, a support block 93, a fixing block 94, and a moving part 95. When the connecting plate 953 rotates, the plate 92 connected to the support block 93 inside the connecting plate 953 can drive the bristles 91 to perform circumferential motion on the surface of the screen plate 6. During the rotation, when the protrusion 7 abuts against the cut surface of the fixing block 94, the fixing block 94 can be forced to drive the support block 93 and the plate 92 to perform lateral movement inside the connecting plate 953. The bristles 91 at the bottom perform intermittent lateral friction on the surface of the screen plate 6, thereby achieving all-round cleaning of the screen plate 6, avoiding clogging of the screen holes and affecting the removal of particles in the abrasive, thus extending the service life of the wear-resistant nozzle 5 and reducing wear factors from the source.

[0024] Brush bristles 91 are fixedly installed at the bottom of the plate 92. A support block 93 is fixedly installed at the top of the plate 92, and a fixing block 94 is fixedly installed at the top of the support block 93. When the cut surface of the fixing block 94 is abutted, the fixing block 94 can be forced to drive the support block 93 and the plate 92 to move laterally within the connecting plate 953. The moving part 95 includes a flat rod 951, which passes through the support block 93 and is slidably connected to it. The side of the support block 93 is fixedly connected to one end of a spring 952, and the other end of the spring 952 is fixedly installed on the arc surface of the flat rod 951. The flat rod 951 ensures the stability of the support block 93 during lateral movement. The flat rod 951 is fixedly installed on the inner wall of the connecting plate 953. The top of the connecting plate 953 is in contact with the bottom of the fixing block 94, and a support rod 954 is fixedly installed at the top of the fixing block 94. When the cut surface of the fixing block 94 is abutted, the support rod 954 can be driven to slide along the surface of the connecting plate 953. A vertical rod 955 is fixedly installed on the top of the connecting plate 953. The vertical rod 955 passes through the knocking rod 956 and is slidably connected to the knocking rod 956. A triangular block 958 is fixedly installed on the side of the knocking rod 956. When the cut surface of the triangular block 958 is abutted, the triangular block 958 can be forcefully driven to move the knocking rod 956 longitudinally along the surface of the vertical rod 955. The inner wall of the knocking rod 956 is fixedly connected to one end of the second spring 957. The other end of the second spring 957 is fixedly installed on the arc surface of the vertical rod 955. When the knocking rod 956 is no longer under force, it can spring up under the action of the second spring 957. The connecting plate 953 is fixedly installed on the arc surface of the rotating rod 959. The rotating rod 959 passes through the fixed plate 8 and is rotatably connected to the fixed plate 8. A motor 950 is fixedly installed on the top of the fixed plate 8. The output shaft of the motor 950 is fixedly connected to the top of the rotating rod 959. The output shaft of the motor 950 is forcefully driven to make the rotating rod 959 and the connecting plate 953 rotate within the fixed plate 8.

[0025] In this invention, during use, the abrasive is poured into the hopper 1 of the sandblasting machine. The sieve plate 6 inside the hopper 1 sieves the abrasive, and large particles in the abrasive will remain on the top of the sieve plate 6. During the sieving process, the motor 950 on the top of the fixed plate 8 is started. When the output shaft of the motor 950 is driven by force to rotate the rotating rod 959, the connecting plate 953 fixed to the surface of the rotating rod 959 will rotate synchronously. When the connecting plate 953 rotates, the plate 92 connected to the support block 93 inside the connecting plate 953 can drive the bristles 91 to perform circumferential motion on the surface of the sieve plate 6. During the rotation, when the protrusion 7 abuts against the cut surface of the fixed block 94, the fixed block 94 can be driven by force to move the support block 93 and the plate 92 laterally within the connecting plate 953, and the bristles 91 at the bottom perform intermittent lateral friction on the surface of the sieve plate 6, thereby achieving all-round cleaning of the sieve plate 6 and avoiding clogging of the sieve holes, which would affect the removal of particles in the abrasive. In addition, this extends the service life of the wear-resistant nozzle 5 and reduces wear factors from the source. When the fixed block 94 moves on the surface of the connecting plate 953, the support rod 954 fixed on the surface of the fixed block 94 will move towards the triangular block 958. When the cut surface of the triangular block 958 is abutted, it can drive the knocking rod 956 to lift along the surface of the vertical rod 955. When the cut surface of the triangular block 958 is no longer abutted, the knocking rod 956 can be lifted by the force of the spring 957, thereby intermittently knocking the top of the screen plate 6, thereby accelerating the outflow of abrasive and avoiding long-term residence that affects subsequent sandblasting operations. After screening, the abrasive in the machine tank 1 is extracted by the pump body 3 and the connecting pipe 2 and transported into the wear-resistant nozzle 5 through the conveying pipe 4. The wear-resistant nozzle 5 sprays out the abrasive. Since the large particles in the abrasive are removed by the screen plate 6, the wear-resistant nozzle 5 can be less likely to be blocked during use, thereby enhancing its wear resistance during use.

[0026] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
