Description

Technical Field

[0001] This utility model belongs to the technical field of aluminum profile processing equipment, and in particular relates to a circulating sandblasting device for aluminum profiles. Background Technology

[0002] In the surface treatment process of aluminum profiles, sandblasting is a key step to improve surface roughness and cleanliness. Traditional sandblasting equipment suffers from problems such as low sand utilization, serious dust pollution, and frequent manual maintenance. Moreover, the non-circulating operation mode leads to high production costs and significant environmental pressure. With the increasing demand for efficient and green production in the aluminum profile processing industry, the development of sandblasting equipment with sand recycling, dust filtration and purification, and automated control functions has become a trend. Such equipment can achieve the reuse of sand through a closed-loop system, while integrating dust removal devices to reduce environmental pollution, thus meeting the multiple needs of modern manufacturing for energy conservation, environmental protection, and capacity improvement.

[0003] However, existing circulating sandblasting devices for aluminum profiles are not easy to separate the sprayed abrasive during use, causing the abrasive to accumulate on the aluminum profile. The accumulated abrasive will block the newly sprayed abrasive, reducing the speed at which the new abrasive comes into contact with the aluminum profile, thus affecting the sanding effect. Utility Model Content

[0004] The purpose of this utility model is to provide a circulating sandblasting device for aluminum profiles. By setting a separation part, it solves the problem that existing circulating sandblasting devices for aluminum profiles are not easy to separate the sprayed abrasive during use, resulting in abrasive accumulation on the aluminum profile material. The accumulated abrasive will block the newly sprayed abrasive, reduce the speed at which the new abrasive comes into contact with the aluminum profile material, and thus affect the sanding effect.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a circulating sandblasting device for aluminum profiles, comprising a housing and a protective door installed inside the housing, and further comprising: a separation section located inside the housing for separating abrasive sand; and a circulation section installed inside the housing for circulating abrasive sand; wherein, aluminum profile material is placed in the separation section, and then the aluminum profile material is sanded by the circulation section, and the sanded sand is separated again by the action of the separation section and re-enters the circulation section.

[0007] Furthermore, the separation section includes a rotating assembly located inside the chassis; and two latching assemblies, both located inside the chassis; wherein the two latching assemblies are mirror images of each other, and both latching assemblies are used to ensure the normal operation of the rotating assembly.

[0008] Furthermore, the circulation section includes a collection component installed inside the chassis for collecting abrasive sand; and a sandblasting component, wherein several sandblasting components are provided, and all of the sandblasting components are installed inside the chassis; wherein the collection component is used to collect the abrasive sand separated by the separation section, and the several sandblasting components are used to reuse the abrasive sand collected by the collection component.

[0009] Furthermore, the rotating assembly includes two rotating blocks rotatably connected to the inner wall of the chassis, a mesh cylinder fixedly connected between the two rotating blocks, a cylinder cover hinged to the mesh cylinder, and a power component located on the left side of the chassis. The two rotating blocks are mirror images of each other, and the mesh cylinder is used to store aluminum profiles. The power component includes a bracket fixedly connected to the left side of the chassis, a motor fixedly connected to the inner wall of the bracket, and a rotating shaft rotatably connected to the inner wall of the chassis. The output shaft of the motor is fixedly connected to the rotating shaft via a coupling. The right side of the rotating shaft is fixedly connected to the rotating block located on the left side, and the left side of the rotating shaft extends outside the chassis, while the right side extends inside the chassis. This allows the aluminum profiles inside the mesh cylinder to tumble, shaking off the abrasive accumulated on its surface. Simultaneously, the tumbling aluminum profiles make full contact with the abrasive, ensuring grinding efficiency.

[0010] Furthermore, the buckle assembly includes a groove 1 formed on the rotating block, and a groove 2 formed on the bottom inner wall of the groove 1, with a limiting component disposed in the groove 2; wherein, the side of the groove 1 near the cylinder cover extends out of the rotating block, and the limiting component includes a spring disposed in the groove 2, and a slider is slidably connected to the inner wall of the groove 2, and the side of the cylinder cover near the groove 1 is fixedly connected to the limiting block; wherein, the top of the spring is fixedly connected to the slider, and the bottom of the spring is fixedly connected to the groove 2, which can restrict the cylinder cover on the mesh cylinder, preventing the aluminum profile material from falling out of the mesh cylinder during the tumbling process, thereby ensuring the stability of the grinding.

[0011] Furthermore, the collection assembly includes a collection trough inside a chassis, a motor sleeve fixedly connected to the bottom of the chassis, and an agitator disposed inside the motor sleeve. The collection trough is used to hold abrasive sand. The agitator includes a second motor fixedly connected to the inner wall of the motor sleeve. A second rotating shaft is rotatably connected to the inner wall of the chassis, and several agitator rods are fixedly connected to the outer wall of the second rotating shaft. The bottom of the second rotating shaft extends into the motor sleeve, and the top of the second rotating shaft extends into the collection trough. The output shaft of the second motor is fixedly connected to the second rotating shaft via a coupling. The several agitator rods are circumferentially distributed, enabling the collection and agitation of the abrasive sand, preventing its accumulation and blockage, thereby ensuring stable circulation.

[0012] Furthermore, the sandblasting assembly includes a sand-flowing pipe fixedly connected to the inner wall of the chassis, a sandblasting gun fixedly connected to the inner wall of the chassis, and an air inlet pipe connected to the sandblasting gun; wherein, the bottom of the sand-flowing pipe is connected to the collection tank, the top of the sand-flowing pipe is connected to the sandblasting gun, and the top of the air inlet pipe extends to the outside of the chassis, which can extract the collected abrasive sand and perform abrasion, thereby completing the cyclic sandblasting.

[0013] This utility model has the following beneficial effects:

[0014] 1. By setting a separation section, when sandblasting is required, the protective door can be opened, and then the slider can be slid to slide in the slot two. At this time, the spring will be compressed and generate elastic force. When the slider slides to the bottom of the limit block, the limit block loses its restriction. At this time, the cylinder cover can be opened, and then the aluminum profile material can be put into the grid cylinder. Then the cylinder cover can be reset and locked by the buckle assembly. Then the protective door can be closed, and the circulation section can be started to sandblast the aluminum profile material in the grid cylinder. At this time, the motor can be started, and its output shaft drives the rotating block to rotate slowly through the rotating shaft one, thereby causing the aluminum profile material in the grid cylinder to tumble. At this time, the abrasive sprayed out will fall from the grid on the grid cylinder and the cylinder cover after grinding the aluminum profile material. This can separate the sprayed abrasive, prevent the abrasive from accumulating on the aluminum profile material, and avoid reducing the speed when the new abrasive comes into contact with the aluminum profile material, thus ensuring the grinding effect. At the same time, it can also cause the aluminum profile material to tumble, so that all parts can be ground evenly.

[0015] 2. By setting up a circulation section, compressed air is injected into the sandblasting gun through the air inlet pipe during sandblasting, creating negative pressure inside the gun. At this time, the abrasive in the collection tank is drawn into the gun through the sand flow pipe and ejected with the high-speed air. When the ejected abrasive falls from the separation tank, it falls into the collection tank, completing the circulation. During this process, motor two can be started to rotate its output shaft, which in turn drives the stirring rod to rotate, stirring the abrasive in the collection tank and preventing bridging. This allows the abrasive separated after sandblasting to be collected and recycled for sandblasting, eliminating the need to frequently add new abrasive. This not only improves sandblasting efficiency but also reduces costs.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0033] A specific application of this embodiment is as follows: When sandblasting is required, the protective door 102 can be opened, and then the slider 224 can be slid to slide within the groove 222. At this time, the spring 223 will be compressed and generate elastic force. When the slider 224 slides below the limit block 225, the limit block 225 loses its restriction. At this time, the cylinder cover 213 can be opened, and then the aluminum profile material can be placed into the mesh cylinder 212. Then, the cylinder cover 213 can be reset and locked by the buckle assembly 22. Then, the protective door 102 can be closed, and the circulation unit 3 can be started to sandblast the aluminum profile material in the mesh cylinder 212. At this time, the motor 215 can be started, and its output shaft can drive the rotating block 211 to rotate slowly through the rotating shaft 216, thereby causing the aluminum profile material in the mesh cylinder 212 to tumble. At this time, the abrasive sprayed out will fall from the mesh on the mesh cylinder 212 and the cylinder cover 213 after sandblasting the aluminum profile material. During sandblasting, compressed air is injected into the sandblasting gun 322 through the air inlet pipe 323, and a negative pressure is generated inside the sandblasting gun 322. At this time, the abrasive in the collection tank 311 is drawn into the sandblasting gun 322 through the sand flow pipe 321 and sprayed out with the high-speed air. When the sprayed abrasive falls from the separation section 2, it falls into the collection tank 311, completing the cycle. During this process, the motor 313 can be started to rotate its output shaft, which in turn drives the stirring rod 315 to rotate through the rotating shaft 314, stirring the abrasive in the collection tank 311 to avoid arching. The sandblasting gun 322 is a W301-ES-26-LH sandblasting gun, which uses compressed air to form a high-speed airflow, which drives the abrasive to be sprayed out from the nozzle. The high-speed abrasive impacts the surface of the workpiece, and through grinding and impact, it achieves the effects of rust removal, deburring, and surface roughening. It is suitable for surface treatment of various materials such as metals and non-metals.
