[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] First Embodiment

[0030] Please refer to the following: Figure 1 , Figure 2 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a sandblasting equipment for flat workpieces provided by this utility model; Figure 2 for Figure 1 The diagram shows a top view of the structure. A sandblasting equipment for flat workpieces includes: a conveying assembly 1;

[0031] Sandblasting chamber 2, which is disposed on the outer side of the conveying assembly 1;

[0032] A sandblasting tank 3 is disposed on the side of the sandblasting chamber 2;

[0033] Leveling component 5, which is disposed at the input end of the conveying component 1;

[0034] Dust removal component 6, which is disposed on the side of the conveying component 1;

[0035] Cleaning component 7 is located at the output end of the sandblasting chamber 2.

[0036] A bracket 31 is provided on the outer side of the sandblasting tank 3, and an electrical control box 4 is fixedly installed on the side of the bracket 31.

[0037] An exhaust vent 61 is fixedly installed on the back of the dust removal component 6.

[0038] The conveying assembly 1 uses a roller made of high-quality carbon steel seamless steel pipe and tempered shaft head welded together, which ensures a load capacity of 1500kg / m and coaxiality. The roller surface is covered with black wear-resistant rubber (nitrile rubber), which can ensure the load-bearing strength and service life of the workpiece and prevent the workpiece from being scratched during the conveying process. The conveying assembly 1 is driven by a speed-regulating motor, which realizes stepless speed regulation of the workpiece conveying speed from 0 to 5 m / min. The conveying speed can be flexibly adjusted according to different processing requirements. Tooling limit devices are set at the input and output ends of the conveying assembly 1 to effectively prevent the workpiece from deviating during the conveying process and ensure that the workpiece can accurately enter and leave each processing area.

[0039] The leveling assembly 5 consists of multiple leveling rollers. The leveling rollers are made of high-hardness, high-wear-resistant alloy steel to ensure that they are not easily deformed during long-term use.

[0040] The main frame of the sandblasting room 2 is welded from 70×3 national standard square steel. The exterior wall is made of fire-retardant hollow cleanroom panels, and the corners are made of high-quality aluminum alloy, which not only ensures the sturdiness of the room, but also has good sound insulation and fire resistance. The interior wall is covered with 3mm wear-resistant protective rubber, which effectively prevents the sand from corroding the wall and extends the service life of the room. The floor of the sandblasting room 2 is made of grid floor, which has a large load-bearing capacity and facilitates the collection and cleaning of sand. The sandblasting tank 3 adopts a double-layer tank design and the tank body adopts a conical structure, which increases the flowability of sand. Through the coordinated work of control components such as material level sensor, air inlet control valve, air outlet control valve, and pneumatic butterfly valve, automatic sand feeding and sandblasting functions are realized. The upper tank feeding switch is equipped with a position detection switch. The air inlet valve can only be opened when the feeding valve is detected to be closed, ensuring the safety of the pressure tank.

[0041] The core of dust collection component 6 is a pulse-jet cartridge dust collector, internally equipped with 24 high-precision filter cartridges made of polyurethane. These cartridges offer advantages such as high filtration accuracy (0.5µm), large filtration area (18m²), and long service life (over one year with timely maintenance). When dust-laden air enters the dust collector, it is first filtered by the cartridges, with dust trapped on their surface. The pulse-jet backflushing mechanism periodically activates, injecting high-pressure gas into the cartridges through the air tank, pulse solenoid valve, and air pipes, blowing the dust off the cartridge surface and into the ash hopper at the bottom of the dust collector. The dust is then cleaned by a cleaning trolley. The dust collector's fan power is 18.5KW, with an air volume of 14734m³ / h-24677m³ / h and an air pressure of 2367Pa-1581Pa, ensuring timely and effective collection and treatment of dust generated during sandblasting.

[0042] The working principle of the sandblasting equipment for flat workpieces provided by this utility model is as follows:

[0043] S1. Workpiece conveying: The flat workpiece is placed on the conveying component 1. The conveying component 1 is started and drives the workpiece to move along the set route. At the input end of the conveying component 1, the leveling component 5 starts to work and performs leveling treatment on the uneven flat workpiece to ensure that the workpiece can be evenly stressed in the subsequent sandblasting process and ensure the consistency of the sandblasting effect.

[0044] S2. Sandblasting: When the workpiece is conveyed to position 2 of the sandblasting room, the sandblasting operation begins. The sand in the sandblasting tank 3 is sprayed onto the surface of the workpiece through the spray gun under the action of compressed air. The movement mode of the spray gun is set according to different needs. In the automatic conveying sandblasting machine, some spray guns can move along the trajectory set in the program with the spray gun movement system to sandblast the upper and lower surfaces of the workpiece. The sand impacts the surface of the workpiece at high speed, removing rust, oxide scale, burrs, a small amount of oil and paint coatings, etc., increasing the surface area of ​​the workpiece, dispersing the internal residual stress of the structure, hardening the surface of the workpiece, improving the fatigue strength of the workpiece, and reducing stress concentration.

[0045] S3. Dust Treatment: During the sandblasting process, a large amount of dust is generated. The dust collection component 6 starts to work, collecting the dust-laden air from the sandblasting area through the dust extraction pipeline and sending it into the dust collection component 6. The dust collection component 6 adopts a pulse filter cartridge dust collector. The dust-laden air is filtered through the filter cartridge, and the dust is trapped on the surface of the filter cartridge. The purified air is discharged through the exhaust port 61. The pulse backflushing mechanism cleans the filter cartridge regularly to ensure the filtration effect of the filter cartridge and reduce environmental pollution.

[0046] S4. Abrasive Material Recycling: After sandblasting, abrasive material falls from the workpiece surface. The sandblasting room and the automatic conveyor sandblasting machine each use their own abrasive material recycling systems to recycle the abrasive material. In the sandblasting room, the abrasive material is collected through a honeycomb floor, falls into the longitudinal and transverse spiral return screws, and is then conveyed to the feed hopper by the sandblasting room elevator. In the automatic conveyor sandblasting machine, the abrasive material is collected through a sand collection hopper, and is sent to the feed hopper via a transverse spiral conveyor mechanism and a conveyor elevator. The abrasive material entering the feed hopper is screened by a vibrating screen, and qualified abrasive material enters the storage hopper. It is then reintroduced into the sandblasting process through a pressure-type sandblasting system, realizing the recycling of abrasive material and improving resource utilization.

[0047] Compared with related technologies, the sandblasting equipment for flat workpieces provided by this utility model has the following beneficial effects:

[0048] The design of conveyor component 1 ensures the stability and accuracy of workpiece conveying, allows for adjustment of conveying speed according to processing technology, and prevents workpiece deviation, thus improving processing precision. The leveling component 5 pre-treats the workpiece, resulting in a more uniform sandblasting effect and improved product quality. The rational structural design of the sandblasting chamber 2 and sandblasting tank 3 ensures efficient sandblasting operations while improving equipment safety and durability. The dust removal component 6 effectively handles the dust generated during sandblasting, reducing environmental pollution, protecting the health of operators, and the sand recycling system enables the recycling of sand, reducing production costs.

[0049] Second Embodiment

[0050] Please refer to the following: Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 Based on the first embodiment of this application, which provides a sandblasting equipment for flat workpieces, the second embodiment of this application proposes another sandblasting equipment for flat workpieces. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0051] Specifically, the second embodiment of this application provides a different type of sandblasting equipment for flat workpieces. In this sandblasting equipment, the cleaning component 7 includes a housing 71, a fan 72, an exhaust frame 73, a sweeping component 74, and a shielding component 75. The fan 72 is fixedly installed on the top of the housing 71. The exhaust frame 73 is fixedly installed on the top of the inner side of the housing 71. The output end of the fan 72 is connected to the input end of the exhaust frame 73. The sweeping component 74 is disposed on the inner side of the exhaust frame 73. The shielding component 75 is disposed at the output end of the housing 71. The shielding component 75 includes an mounting strip 751 and a shielding adhesive strip 752. The shielding adhesive strip 752 is fixedly installed on the bottom of the mounting strip 751, and the mounting strip 751 is fixedly installed at the output end of the housing 71.

[0052] The sweeping component 74 includes an elastic component 741, a sweeping execution component 742, and a limiting component 743. The sweeping execution component 742 is disposed at the bottom of the elastic component 741, and the limiting components 743 are respectively disposed at both ends of the elastic component 741.

[0053] The elastic component 741 includes a fixed frame 7411, an extension plate 7412, a first elastic element 7413, and a insertion slot 7414. The top of the fixed frame 7411 is fixedly installed on the top of the inner side of the housing 71. The extension plate 7412 is slidably connected to the inside of the bottom of the fixed frame 7411. The first elastic element 7413 is fixedly installed on the top of the extension plate 7412. The insertion slot 7414 is formed at the bottom of the extension plate 7412. The cleaning execution component 742 includes a insertion plate 7421 and a cleaning brush 742. 2. The cleaning brush 7422 is fixedly installed on the bottom of the plug plate 7421. The positioning grooves 7423 are respectively opened at both ends of the plug plate 7421. The limiting component 743 includes a mounting plate 7431, a positioning rod 7432, and a second elastic member 7433. The mounting plate 7431 is fixedly installed at both ends of the extension plate 7412. The positioning rod 7432 is slidably connected to the inside of the mounting plate 7431. The second elastic member 7433 is sleeved on the outer side of the positioning rod 7432.

[0054] The plug plate 7421 is inserted into the inside of the plug slot 7414, and one end of the positioning rod 7432 is engaged with the inner side of the positioning slot 7423.

[0055] The working principle of the sandblasting equipment for flat workpieces provided by this utility model is as follows:

[0056] After the workpiece is sandblasted and output from the sandblasting room 2, it enters the housing 71 of the cleaning component 7. The blower 72 is started to generate blowing force, which causes the gas to be discharged from the outlet of the exhaust frame 73, thereby blowing away the sandblasting on the top of the workpiece. Then, the workpiece is moved to the bottom of the cleaning component 74 by the conveying component 1.

[0057] At this time, since some sand or impurities may still remain on the surface of the workpiece, the first elastic element 7413 in the elastic component 741 will apply a certain downward pressure to the extension plate 7412, so that the cleaning brush 7422 in the cleaning execution component 742 will fully contact the surface of the workpiece. During the movement of the workpiece, the cleaning brush 7422 will clean the surface of the workpiece to further remove the residual sand and impurities.

[0058] The second elastic element 7433 in the limiting component 743 is sleeved on the outer side of the positioning rod 7432. The positioning rod 7432 is slidably connected to the inside of the mounting plate 7431, and one end of it is engaged with the inner side of the positioning groove 7423. This design can limit the cleaning execution component 742 during the cleaning process, prevent it from shaking excessively, and ensure the stability and consistency of the cleaning effect. After long-term use, when the cleaning brush 7422 is severely worn and needs to be replaced, the user can pull the two positioning rods 7432 to move one end of the positioning rod 7432 out from the inner side of the positioning groove 7423. At this time, due to gravity, the insertion plate 7421 will move out from the inner side of the insertion groove 7414, which makes it convenient for the user to disassemble and replace the cleaning brush 7422.

[0059] The shielding strip 752 in the shielding assembly 75 is fixedly installed at the bottom of the mounting strip 751, and the mounting strip 751 is fixed to the output end of the housing 71. The shielding strip 752 can play a certain sealing role to prevent sand and dust from leaking out from the output end of the housing 71 during the cleaning process, further protecting the environment and reducing pollution to the subsequent processing area.

[0060] Compared with related technologies, the sandblasting equipment for flat workpieces provided by this utility model has the following beneficial effects:

[0061] The design of the cleaning component 7 effectively removes residual sand and impurities from the workpiece surface after sandblasting, further improving product cleanliness. The cooperation between the blower 72 and the exhaust frame 73 achieves initial blowing away of sand from the workpiece surface, improving cleaning efficiency. The coordinated work of the elastic component 741, the cleaning execution component 742, and the limiting component 743 in the sweeping component 74 not only ensures the cleaning effect but also facilitates the replacement of the cleaning brush 7422, reducing equipment maintenance costs. The shielding component 75 effectively prevents leakage of sand and dust during the cleaning process, further reducing environmental pollution and protecting the cleanliness of the working environment and subsequent processing areas.
