Description

Technical Field

[0001] This utility model relates to the field of sandblasting machine technology, specifically to an automatic sandblasting discharge mechanism with a combined structure of conveying pipeline and air inlet pipe. Background Technology

[0002] Automatic sandblasting machines supply abrasive to the sandblasting gun via a discharge mechanism. Existing discharge mechanisms generally include a high-pressure gas device, a material tank, and a conveying pipe. Authorization announcement number CN201410377828.9 discloses an automatic sandblasting machine, which includes a sealed tank, an air inlet pipe disposed within the sealed tank, a conveying pipe for transporting the abrasive placed in the sealed tank to the outside of the sealed tank, and a main frame. The sealed tank is connected to the high-pressure gas device through an air inlet, and the air inlet end of the air inlet pipe extends into the sealed tank and is located above the material level of the placed abrasive. The air outlet end of the air inlet pipe is connected to the conveying pipe, the material inlet end of the conveying pipe extends into the sealed tank and is located below the material level of the placed abrasive, while the material outlet end of the conveying pipe extends to the outside of the sealed tank and connects to the sandblasting gun.

[0003] This existing technology uses a high-pressure gas device to fill a sealed tank with compressed air. The compressed air creates a working pressure inside the sealed tank, and this working pressure forces the sprayed material out of the conveying pipeline. At the same time, a portion of the compressed air inside the sealed tank directly enters the air inlet pipe through the air inlet end, and then enters the conveying pipeline through the air outlet end of the air inlet pipe, where it mixes with the sprayed material. At this time, the sprayed material in the conveying pipeline is diluted by the airflow entering through the air inlet pipe and then moves forward evenly suspended or attached to the wall in the conveying pipeline. This effectively prevents the sprayed material from accumulating or clogging at the feed end of the conveying pipeline and in the conveying pipeline, thus achieving uniform discharge.

[0004] However, when adding sand, the tank needs to be opened. Opening the tank will cause high-pressure air to leak out, which will make it impossible to maintain a stable working pressure inside the tank, thus seriously affecting the discharge of sand. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an automatic sandblasting discharge mechanism with a combined structure of conveying pipeline and air inlet pipe, which solves the problems existing in the above-mentioned prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic sandblasting discharge mechanism with a combined conveying pipeline and air inlet pipe structure, comprising a base, on which an air compressor and a tank are mounted. The air compressor is connected to the tank via an air delivery pipe, and the tank is connected to a conveying pipe, which is connected to an air inlet pipe. A feed pipe is connected to the top of the tank, and a feed hopper is connected to the top of the feed pipe. A cylinder is mounted on the feed hopper, and the cylinder is connected to an upper plate via a rotating device. An upper bearing matching the inner wall of the feed pipe is rotatably connected to the outer side of the upper plate. A guide rod is fixedly connected to the bottom of the upper plate, and a lower plate is slidably sleeved on the guide rod. A lifting device is rotatably connected to the outer ring of the lower plate, and the lower plate is in contact with the inner wall of the top of the tank.

[0007] Preferably, the rotating device includes a mounting box connected to a cylinder, and a geared motor is detachably connected inside the mounting box. The output shaft of the geared motor is fixedly connected to the upper plate.

[0008] Preferably, heat dissipation meshes can be detachably connected to both sides of the mounting box.

[0009] Preferably, a filter structure is detachably connected to the air intake end of the air intake pipe.

[0010] Preferably, the filter structure is a conical filter screen.

[0011] Preferably, the lifting device includes a lower bearing, which is rotatably connected to the outer ring of the lower plate. The lower bearing is located inside the tank. A second cylinder is provided on the feed hopper. The second cylinder vertically penetrates the feed hopper, and the piston rod of the second cylinder penetrates the tank. The piston rod of the second cylinder is connected to the outer ring of the lower bearing.

[0012] This utility model provides an automatic sandblasting discharge mechanism with a combined structure of conveying pipeline and air inlet pipe. Compared with the prior art, it has the following advantages: 1. This automatic sandblasting discharge mechanism with a combined conveying pipeline and air inlet pipe structure allows for the addition of sand to the tank. First, sand is fed into the feed pipe from the feed hopper. Then, a cylinder drives the upper plate downwards, causing the upper bearing to enter the feed pipe and seal the top. The upper plate then continues to move downwards, simultaneously moving the lower bearing, which in turn moves the lower plate downwards. This allows the sand in the feed pipe between the upper and lower plates to be discharged into the tank. Because the top of the feed pipe is sealed by the upper plate and upper bearing, high-pressure gas can continue to be introduced into the tank while adding sand, preventing continuous leakage and minimizing the impact on sand discharge.

[0013] 2. The automatic sandblasting discharge mechanism with a combined conveying pipeline and air inlet pipe structure, after the lower plate leaves the inner wall of the top of the tank, rotates the upper plate through a rotating device, causing the guide rod to drive the lower plate to rotate as well. This allows the sand to be quickly discharged into the tank under the action of centrifugal force. By shortening the discharge time, the impact of the bottom opening of the feed pipe on the air pressure inside the tank can be reduced, further reducing the impact on the discharge of sand.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] See Figures 1-5 This utility model provides the following two technical solutions: The first embodiment: an automatic sandblasting discharge mechanism with a mixed structure of conveying pipeline and air inlet pipe includes a base 1, an air compressor 2 and a tank 3 are provided on the base 1, the air compressor 2 is connected to the tank 3 through an air supply pipe 4, the tank 3 is connected to a conveying pipe 5, an air inlet pipe 6 is connected to the conveying pipe 5, the air inlet end of the air inlet pipe 6 extends into the tank 3 and is located above the sand material level, the air outlet end of the air inlet pipe 6 is connected to the conveying pipe 5, the feed end of the conveying pipe 5 extends into the tank 3 and is located below the sand material level, the discharge end of the conveying pipe 5 is connected to a sandblasting gun through a pipe, and a flow regulating valve is also provided on the air inlet pipe 6; The top of the tank body 3 is connected to a feed pipe 7, and the top of the feed pipe 7 is connected to a feed hopper 8. A cylinder 9 is installed on the feed hopper 8. The cylinder 9 is connected to an upper plate 10 through a rotating device. The outer side of the upper plate 10 is rotatably connected to an upper bearing 15 that matches the inner wall of the feed pipe 7. A guide rod 11 is fixedly connected to the bottom of the upper plate 10. A lower plate 12 is slidably sleeved on the guide rod 11. A lifting device is rotatably connected to the outer ring of the lower plate 12. The lower plate 12 is in contact with the inner wall of the top of the tank body 3.

[0018] When sand needs to be added to tank 3, the sand is first fed into feed pipe 7 through feed hopper 8, so that the sand falls above the lower plate 12. In order to have more sand in feed pipe 7, the upper plate 10 can be driven to move down by cylinder 9, so that the upper bearing 15 also moves down to push and squeeze the sand in feed pipe 7. Then it moves up again to continue feeding sand, and the operation is repeated. When a lot of sand is squeezed, the upper bearing 15 enters the feed pipe 7 to seal the top of feed pipe 7. Then the upper plate 10 can continue to move down. At the same time, the lower plate 12 is moved at the same speed by lifting device, so that the sand in feed pipe 7 between upper plate 10 and lower plate 12 can be discharged into tank 3. Since the top of feed pipe 7 is sealed by upper plate 10 and upper bearing 15, high-pressure gas can continue to be introduced into tank 3 when adding sand, so as not to cause high-pressure gas to leak out continuously, thereby reducing the impact on sand discharge.

[0019] When the lower plate 12 leaves the inner wall of the top of the tank 3 to discharge material, the upper plate 10 is rotated by the rotating device, so that the guide rod 11 drives the lower plate 12 to rotate as well. This allows the sand to be quickly discharged into the tank 3 under the action of centrifugal force. By shortening the discharge time, the impact of the bottom opening of the feed pipe 7 on the air pressure inside the tank 3 can be reduced, further reducing the impact on the discharge of sand. After the discharge is completed, the top of the lower plate 12 is moved up to contact the inner wall of the top of the tank 3, and then the upper plate 10 is moved away from the feed pipe 7.

[0020] The rotating device includes a mounting box 16 connected to cylinder 9. A geared motor 17 is detachably connected inside the mounting box 16. The output shaft of the geared motor 17 is fixedly connected to the upper plate 10. The geared motor 17 drives the upper plate 10 to rotate. The mounting box 16 prevents the geared motor 17 from being affected by the sand.

[0021] Both sides of the mounting box 16 are detachably connected to heat dissipation mesh 18, which does not affect the heat dissipation of the geared motor 17.

[0022] Since the sand is centrifugally thrown into the tank 3, it can easily enter the air inlet pipe 6 and affect the airflow. Therefore, by detachably connecting a filter structure to the air inlet end of the air inlet pipe 6, the sand can be blocked without affecting the airflow.

[0023] The lifting device includes a lower bearing 13, which is rotatably connected to the outer ring of the lower plate 12. The lower bearing 13 is located inside the tank body 3. A second cylinder 14 is installed on the feed hopper 8. The second cylinder 14 vertically penetrates the feed hopper 8, and the piston rod of the second cylinder 14 penetrates the tank body 3. The piston rod of the second cylinder 14 is connected to the outer ring of the lower bearing 13. The second cylinder 14 can drive the lifting at the same speed as the first cylinder 9, or it can be used alone to control the lifting of the lower bearing 13 and drive the lower plate 12 to lift. When the lower plate 12 rotates, the rotation is not affected by the lower bearing 13.

[0024] The second implementation method differs from the first implementation method in that the filter structure is a conical filter screen 19, which makes it difficult for sand to remain and ensures air intake.

[0025] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.
