An anisotropic sandblasting disc

Abstract

An anisotropic sandblasting disc, comprising a fixed frame and a sandblasting disc assembly. The sandblasting disc assembly includes a first type of sandblasting disc and a second type of sandblasting disc arranged alternately in the front-back direction. The front-back direction is consistent with the extending direction of the fixed frame. The sandblasting direction of the first type of sandblasting disc is different from that of the second type of sandblasting disc. Since the sandblasting direction of the first type of sandblasting disc is different from that of the second type of sandblasting disc, when the alternately arranged first type of sandblasting disc and second type of sandblasting disc perform sandblasting cleaning on the surface of the workpiece, compared with the prior art, it avoids single vertical-direction sandblasting cleaning and can perform sandblasting cleaning on the workpiece from multiple angles. Obviously, this will be beneficial to more comprehensively sandblasting the outer surface of the workpiece with a convex structure, enabling the sand beam to uniformly strike each surface of the workpiece, obtaining a uniform surface treatment effect, and completing the processing at one time to save costs.

Description

Technical Field

[0001] The present invention relates to the field of sandblasting equipment, and more particularly to an anisotropic sandblasting disc. Background Art

[0002] The sandblasting process is an essential process for some mechanical workpieces and other products during processing. By spraying a sand beam at high speed onto the surface of the workpiece to be processed, the appearance or shape of the workpiece surface is changed, thereby obtaining a certain degree of cleanliness and different roughness, improving the mechanical properties of the workpiece surface. Before sandblasting the workpiece, it is necessary to first fasten and stabilize the workpiece to ensure that it will not shift in position due to the impact when being sprayed by the sand beam, so as to smoothly and accurately carry out the sandblasting work.

[0003] Currently, for the sandblasting treatment of workpieces, the equipment mostly used is a sandblasting disc. The sandblasting disc performs rapid sandblasting on the outer surface of the workpiece through the sandblasting pipe provided inside. It can be seen from the attached Figure 1 that in the prior art, the sandblasting disc usually sandblasts and cleans the outside of the workpiece at an angle perpendicular to the workpiece surface. It can have a good surface treatment effect on workpieces with a flat surface, and the sandblasted surface is evenly distributed without dead corners.

[0004] The problem is that for workpiece products with some protrusions on the surface, only the surface perpendicular to the sandblasting direction can receive uniform sandblasting, and the sandblasting treatment effect on each side of the protrusion part is not good. That is to say, for workpieces with protrusions on the surface, the existing sandblasting discs cannot ensure that the sandblasting and cleaning effect is qualified. Therefore, it is necessary to change the structure of the sandblasting disc so that it can meet both workpieces with a flat surface and workpieces with concave and convex surfaces at the same time. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a brand-new anisotropic sandblasting disc that is completely different from the prior art. When using the anisotropic sandblasting disc to sandblast and clean the outside of the product, it can comprehensively sandblast the protrusion part or the unprocessable part, so that the sand beam can evenly hit each surface of the product, obtaining a uniform surface treatment effect, and completing the processing at one time to save costs.

[0006] To solve the above technical problem, the technical solution adopted by the invention is to provide an anisotropic sandblasting disc, including: a fixed frame, two of the fixed frames are symmetrically arranged left and right; a sandblasting disc assembly, mounted on the two fixed frames; the sandblasting disc assembly includes a first type of sandblasting disc and a second type of sandblasting disc arranged alternately in the front-rear direction, the front-rear direction is the same as the extension direction of the fixed frame, and the sandblasting direction of the first type of sandblasting disc is different from the sandblasting direction of the second type of sandblasting disc.

[0007] By adopting the above-described opposite-direction sandblasting disc, when the workpiece to be sandblasted passes under the opposite-direction sandblasting disc along the front-back direction, since the sandblasting directions of the first type of sandblasting disc and the second type of sandblasting disc are different, when the alternately arranged first type of sandblasting disc and the second type of sandblasting disc perform sandblasting cleaning on the surface of the workpiece, compared with the prior art, the single vertical-direction sandblasting cleaning is avoided, and the workpiece can be sandblasted from multiple angles. Obviously, this is conducive to more comprehensively sandblasting the outer surface of the workpiece with a convex structure, enabling the sand beam to evenly strike each surface of the workpiece, obtaining a uniform surface treatment effect, and completing the processing at one time to save costs.

[0008] As an improvement to the opposite-direction sandblasting disc provided by the present invention, the sandblasting direction of the first type of sandblasting disc and the sandblasting direction of the second type of sandblasting disc are symmetric about a vertical plane, and the vertical plane is perpendicular to the front-back direction. Through the above improvement, with the sandblasting direction of the first type of sandblasting disc and the sandblasting direction of the second type of sandblasting disc being symmetrically coordinated about the vertical plane, the first type of sandblasting disc and the second type of sandblasting disc can achieve synchronous sandblasting cooperation in opposite inclination directions to efficiently sandblast clean some convex workpieces.

[0009] As an improvement to the opposite-direction sandblasting disc provided by the present invention, the first type of sandblasting disc and the second type of sandblasting disc have the same main structure; the main structure includes: a bottom plate, one end of the bottom plate is provided with a hanging plate, and the outside of the hanging plate has a hook portion for hanging on the upper edge of the fixed frame; a feeding pipe, having a feeding port for connecting an external spraying material conveying pipeline, and a first discharge port and a second discharge port communicated with the feeding port; a first feeding branch pipe and a second feeding branch pipe, respectively communicated with the first discharge port and the second discharge port, and the first feeding branch pipe and the second feeding branch pipe are arranged at intervals and in parallel; wherein, the feeding pipe, the first feeding branch pipe and the second feeding branch pipe are located on the lower side of the bottom plate.

The first-type sandblasting pipes and the second-type sandblasting pipes are arranged alternately in the front-rear direction, and the first-type sandblasting pipes and the second-type sandblasting pipes have the same first pipeline structure. The first pipeline structure includes: a first feeding branch pipe, installed and fixed between the first feeding branch pipe and the second feeding branch pipe, and the first feeding branch pipe extends in the left-right direction; a first spraying and dispersing pipe, having a plurality of first sandblasting holes respectively communicating with the first feeding branch pipe, and the axial direction of the first sandblasting holes forms an acute angle with the left-right direction. Through the above improvement, under the alternate installation of the first-type sandblasting pipes and the second-type sandblasting pipes, sandblasting cooperation at multiple positions can be carried out. And due to the fact that the axial direction of the first sandblasting holes forms an acute angle with the left-right direction, the first-type sandblasting pipes and the second-type sandblasting pipes can achieve efficient cleaning of workpieces with convex structures.

[0012] As an improvement to the opposite-direction sandblasting disc provided by the present invention, the first-type sandblasting pipe further has a first sandblasting cover, and a plurality of the first sandblasting covers respectively cover a plurality of the first sandblasting holes in a one-to-one correspondence; the first sandblasting cover has a first through hole axially penetrating the first sandblasting cover and a first through groove opened on the surface of the first sandblasting cover, and the first through hole is located in the first through groove; the extension directions of the first through grooves of each of the first sandblasting covers form the same first angle with the extension direction of the first feeding branch pipe. Through the above improvement, the change of the sandblasting angle is achieved through the first angle formed between the first sandblasting cover and the extension direction of the first feeding branch pipe, so as to adapt to the inclined sandblasting cleaning of workpieces with different convex structures.

[0013] As an improvement to the opposite-direction sandblasting disc provided by the present invention, the second-type sandblasting pipe further has a second sandblasting cover, and a plurality of the second sandblasting covers respectively cover a plurality of the first sandblasting holes in a one-to-one correspondence; the second sandblasting cover has a second through hole axially penetrating the second sandblasting cover and a second through groove opened on the surface of the second sandblasting cover, and the second through hole is located in the second through groove; the extension directions of the second through grooves of each of the second sandblasting covers form the same second angle with the extension direction of the second feeding branch pipe, and the second angle is different from the first angle. Through the above improvement, due to the second angle formed between the second sandblasting cover and the extension direction of the second feeding branch pipe and being different from the first angle, the sandblasting directions of the first-type sandblasting pipes and the second-type sandblasting pipes also form a difference, so that the first-type sandblasting disc can spray sand beams in different directions, further improving the effect of uniform sandblasting cleaning of workpieces with convex structures.

[0014] As an improvement to the anisotropic sandblasting disc provided by the present invention, the second type of sandblasting disc further includes a plurality of third type of sandblasting pipes and fourth type of sandblasting pipes fixedly installed on the main structure. The third type of sandblasting pipes and the fourth type of sandblasting pipes are arranged alternately in the front-back direction, and the third type of sandblasting pipes and the fourth type of sandblasting pipes have the same second pipe structure. The second pipe structure includes: a third feeding branch pipe, fixedly installed between the first feeding branch pipe and the second feeding branch pipe, and the third feeding branch pipe extends in the left-right direction; a second sand spraying and dispersing pipe, having a plurality of third sandblasting holes respectively communicating with the third feeding branch pipe, and the axial direction of the third sandblasting holes forms an acute angle with the left-right direction. Among them, the axial direction of the third sandblasting holes intersects with the axial direction of the first sandblasting holes, and forms an angle with the same angle with the vertical plane respectively. Through the above improvement, the sandblasting direction of the second type of sandblasting disc intersects mirror-symmetrically with the sandblasting direction of the first type of sandblasting disc, ensuring that the entire anisotropic sandblasting disc can perform comprehensive sandblasting cleaning on the workpiece passing from below.

[0015] As an improvement to the anisotropic sandblasting disc provided by the present invention, the third type of sandblasting pipe further includes a third sandblasting cover, and a plurality of the third sandblasting covers are respectively covered on a plurality of the third sandblasting holes in a one-to-one correspondence. The third sandblasting cover has a third through hole axially penetrating the third sandblasting cover and a third through groove opened on the surface of the third sandblasting cover, and the third through hole is located in the third through groove. The extending direction of the third through groove of each of the third sandblasting covers forms the same third angle with the extending direction of the third feeding branch pipe. Through the above improvement, the change of the sandblasting angle is realized through the third angle formed by the third sandblasting cover and the extending direction of the third feeding branch pipe, so as to adapt to the inclined sandblasting cleaning of workpieces with different convex structures.

[0016] As an improvement to the anisotropic sandblasting disc provided by the present invention, the fourth type of sandblasting pipe further includes a fourth sandblasting cover, and a plurality of the fourth sandblasting covers are respectively covered on a plurality of the third sandblasting holes in a one-to-one correspondence.

The extending direction of the fourth through groove of each of the fourth sandblasting covers forms the same fourth angle with the extending direction of the fourth feeding branch pipe, and the fourth angle is different from the third angle. Through the above improvement, through the fourth angle formed by the fourth sandblasting cover and the extending direction of the fourth feeding branch pipe, and in cooperation with the third angle, the sandblasting directions of the third type of sandblasting pipe and the fourth type of sandblasting pipe also form a difference, so that the second type of sandblasting disc can spray sand beams in different directions, further improving the effect of uniform sandblasting cleaning of workpieces with convex structures.

[0017] The anisotropic sandblasting disc implementing the present invention can at least achieve the following beneficial effects: By adopting the anisotropic sandblasting disc of the above technical solution, when the workpiece to be sandblasted and cleaned passes under the anisotropic sandblasting disc along the front-back direction, since the sandblasting directions of the first type of sandblasting disc and the second type of sandblasting disc are different, therefore, when the alternately arranged first type of sandblasting disc and the second type of sandblasting disc perform sandblasting cleaning on the surface of the workpiece, compared with the prior art, it avoids single vertical-direction sandblasting cleaning and can perform sandblasting cleaning on the workpiece from multiple angles. Obviously, this will be beneficial to more comprehensively sandblasting the outer surface of the workpiece with a convex structure, enabling the sand beam to evenly strike each surface of the workpiece, obtaining a uniform surface treatment effect, and completing the processing at one time to save costs.

The terms used in the description of the invention herein are only for the purpose of describing specific embodiments and are not intended to limit the invention.

[0041] This embodiment provides an anisotropic sandblasting disc. Refer to Figure 2 , Figure 2 , which is a schematic three-dimensional structure diagram of the anisotropic sandblasting disc provided in this embodiment. The anisotropic sandblasting disc includes a fixed frame 1 and a sandblasting disc assembly 2. As can be seen in Figure 2 , the two fixed frames 1 are symmetrically arranged left and right, and the sandblasting disc assembly 2 is mounted on the two fixed frames 1. The sandblasting disc assembly 2 includes a first type of sandblasting disc P1 and a second type of sandblasting disc P2 arranged alternately in the front-back direction. The front-back direction is consistent with the extension direction of the fixed frame 1. The sandblasting direction of the first type of sandblasting disc P1 is different from that of the second type of sandblasting disc P2.

As can be seen from Figure 3a , Figure 3b and Figure 4 , the first type of sandblasting disc P1 and the second type of sandblasting disc P2 have the same main structure; the main structure includes a bottom plate 21, a feed pipe 22, a first feed branch pipe 23 and a second feed branch pipe 24. One end of the bottom plate 21 is provided with a hanging plate 21a, and the outside of the hanging plate 21a has a hook portion that is hooked to the upper edge of the fixed frame 1; the feed pipe 22 has a feed port for connecting an external spray material conveying pipeline, and a first discharge port and a second discharge port that are communicated with the feed port; the first feed branch pipe 23 and the second feed branch pipe 24 are respectively communicated with the first discharge port and the second discharge port, and the first feed branch pipe 23 and the second feed branch pipe 24 are arranged at intervals and in parallel; wherein, the feed pipe 22, the first feed branch pipe 23 and the second feed branch pipe 24 are located on the lower side of the bottom plate 21. When using the anisotropic sandblasting disc provided in this embodiment to perform sandblasting cleaning on the outer side of the product, through the cooperation of the different sandblasting directions of the first type of sandblasting disc P1 and the second type of sandblasting disc P2, the outer surface of some convex workpieces or flat workpieces can be subjected to inclined sandblasting cleaning, so that each side part of the convex workpiece can receive the injection of the sand beam, thereby realizing comprehensive and efficient cleaning.

[0042] Continue to refer to Figure 3a , from Figure 3aAs can be seen, the first type of sandblasting disc P1 also has a plurality of first type of sandblasting pipes T1 and second type of sandblasting pipes T2 that are installed and fixed to the main structure. The first type of sandblasting pipes T1 and the second type of sandblasting pipes T2 are arranged alternately in the front-rear direction, and the first type of sandblasting pipes T1 and the second type of sandblasting pipes T2 have the same first pipe structure; the first pipe structure includes: a first feeding branch pipe 211, which is installed and fixed between the first feeding branch pipe 23 and the second feeding branch pipe 24, and the first feeding branch pipe 211 extends in the left-right direction; a first spraying and dispersing pipe 212, which has a plurality of first sandblasting holes 213 respectively communicating with the first feeding branch pipe 211, and the included angle between the axial direction of the first sandblasting holes 213 and the left-right direction is an acute angle. When using the anisotropic sandblasting disc provided in this embodiment to perform sandblasting cleaning on the outer side of the product, through the alternate installation of the first type of sandblasting pipes T1 and the second type of sandblasting pipes T2, sandblasting cooperation at multiple positions can be carried out, and due to the included angle between the axial direction of the first sandblasting holes 213 and the left-right direction being an acute angle, the first type of sandblasting pipes and the second type of sandblasting pipes can achieve efficient cleaning of workpieces with convex structures.

[0043] See Figure 5a 、 Figure 5b 、 Figure 6a 、 Figure 6b 、 Figure 9 and Figure 10 , Figure 5a is a top view structural schematic diagram of the first type of sandblasting pipe in the anisotropic sandblasting disc provided in this embodiment, Figure 5b is a front view structural schematic diagram of the first type of sandblasting pipe in the anisotropic sandblasting disc provided in this embodiment, Figure 6a is a top view structural schematic diagram of the second type of sandblasting pipe in the anisotropic sandblasting disc provided in this embodiment, Figure 6b is a front view structural schematic diagram of the second type of sandblasting pipe in the anisotropic sandblasting disc provided in this embodiment, Figure 9 is a front view truncated schematic diagram of the first type of sandblasting pipe in the first type of sandblasting disc provided in this embodiment, Figure 10 is a cross-sectional schematic diagram of the first type of sandblasting pipe in the first type of sandblasting disc provided in this embodiment. From Figure 5a 、 Figure 5b 、 Figure 6a 、 Figure 6b 、 Figure 9 and Figure 10As can be seen, the first type of sandblasting pipe T1 further has a first sandblasting cover 214, and a plurality of the first sandblasting covers 214 are respectively covered on a plurality of the first sandblasting holes 213 in a one-to-one correspondence; the first sandblasting cover 214 has a first through hole axially penetrating the first sandblasting cover 214 and a first through groove opened on the surface of the first sandblasting cover 214, and the first through hole is located in the first through groove; the extension direction of the first through groove of each of the first sandblasting covers 214 forms the same first angle X1 with the extension direction of the first feeding branch pipe 211. The second type of sandblasting pipe T2 further has a second sandblasting cover 214a, and a plurality of the second sandblasting covers 214a are respectively covered on a plurality of the first sandblasting holes 213 in a one-to-one correspondence; the second sandblasting cover 214a has a second through hole axially penetrating the second sandblasting cover 214a and a second through groove opened on the surface of the second sandblasting cover 214a, and the second through hole is located in the second through groove; the extension direction of the second through groove of each of the second sandblasting covers 214a forms the same second angle X2 with the extension direction of the second feeding branch pipe 212a, and the second angle X2 is different from the first angle X1. It should be noted that by adjusting the first angle X1 formed between the first sandblasting cover 214 and the extension direction of the first feeding branch pipe 211, the sandblasting angle can be changed, so as to adapt to the inclined sandblasting cleaning of workpieces with different convex structures. Most importantly, due to the second angle X2 formed between the second sandblasting cover 214a and the extension direction of the second feeding branch pipe 212a, and the second angle X2 is different from the first angle X1, the sandblasting directions of the first type of sandblasting pipe and the second type of sandblasting pipe also form a difference, so that the first type of sandblasting disc can eject sand beams in different directions, further improving the effect of uniform sandblasting cleaning of workpieces with convex structures.

[0044] Continue to refer to Figure 3b , from Figure 3bAs can be seen, the second type of sandblasting disc P2 further has a plurality of third type of sandblasting pipes T3 and fourth type of sandblasting pipes T4 which are installed and fixed on the main body structure. The third type of sandblasting pipes T3 and the fourth type of sandblasting pipes T4 are arranged alternately in the front-back direction, and the third type of sandblasting pipes T3 and the fourth type of sandblasting pipes T4 have the same second pipe structure. The second pipe structure includes: a third feeding branch pipe 231 which is installed and fixed between the first feeding branch pipe 23 and the second feeding branch pipe 24 and extends in the left-right direction; a second spraying and dispersing pipe 232 which has a plurality of third sandblasting holes 234 respectively communicated with the third feeding branch pipe 231, and the included angle between the axial direction of the third sandblasting hole 234 and the left-right direction is an acute angle. Among them, the axial direction of the third sandblasting hole 234 intersects with the axial direction of the first sandblasting hole 213, and forms an included angle with the same angle with the vertical plane respectively. So that the sandblasting direction of the second type of sandblasting disc intersects mirror-symmetrically with the sandblasting direction of the first type of sandblasting disc, ensuring that the entire reverse-direction sandblasting disc can perform a comprehensive sandblasting cleaning on the workpiece passing from below.

[0045] See Figure 7a , Figure 7b , Figure 8a , Figure 8b , Figure 11 and Figure 12 , Figure 7a is a top view structural diagram of the third type of sandblasting pipe in the reverse-direction sandblasting disc provided by this embodiment. Figure 7b is a front view structural diagram of the third type of sandblasting pipe in the reverse-direction sandblasting disc provided by this embodiment. Figure 8a is a top view structural diagram of the fourth type of sandblasting pipe in the reverse-direction sandblasting disc provided by this embodiment. Figure 8b is a front view structural diagram of the fourth type of sandblasting pipe in the reverse-direction sandblasting disc provided by this embodiment. Figure 11 is a front view structural diagram of the third type of sandblasting pipe in the second type of sandblasting disc provided by this embodiment. Figure 12 is a cross-sectional view of the third type of sandblasting pipe in the second type of sandblasting disc provided by this embodiment. In Figure 7a , Figure 7b , Figure 8a , Figure 8b , Figure 11 and Figure 12As can be seen, the third type of sandblasting pipe T3 further has a third sandblasting cover 233, and a plurality of the third sandblasting covers 233 are respectively and correspondingly covered on a plurality of the third sandblasting holes 234; the third sandblasting cover 233 has a third through hole axially penetrating the third sandblasting cover 233 and a third through groove opened on the surface of the third sandblasting cover 233, and the third through hole is located in the third through groove; the extension direction of the third through groove of each of the third sandblasting covers 233 forms the same third included angle X3 with the extension direction of the third feed branch pipe 231. The fourth type of sandblasting pipe T4 further has a fourth sandblasting cover 232a, and a plurality of the fourth sandblasting covers 232a are respectively and correspondingly covered on a plurality of the third sandblasting holes 234; the fourth sandblasting cover 232a has a fourth through hole axially penetrating the fourth sandblasting cover 232a and a fourth through groove opened on the surface of the fourth sandblasting cover 232a, and the fourth through hole is located in the fourth through groove; the extension direction of the fourth through groove of each of the fourth sandblasting covers 232a forms the same fourth included angle X4 with the extension direction of the fourth feed branch pipe 231a, and the fourth included angle X4 is different from the third included angle X3. It should be noted that when using the anisotropic sandblasting disc provided in this embodiment to perform sandblasting cleaning on the outer side of the product, by adjusting the third included angle X3 formed by the extension direction of the third sandblasting cover 233 and the third feed branch pipe 231, it can be adapted to the inclined sandblasting cleaning of workpieces with different convex structures. The most crucial thing is that the fourth included angle X4 formed by the extension direction of the fourth sandblasting cover 232a and the fourth feed branch pipe 231a is different from the third included angle X3, so that the sandblasting directions of the third type of sandblasting pipe and the fourth type of sandblasting pipe also form a difference, thereby enabling the second type of sandblasting disc itself to eject sand beams in different directions, further improving the effect of uniform sandblasting cleaning of workpieces with convex structures.

[0046] According to the above description, when using the reverse sandblasting disc provided in this embodiment to perform sandblasting cleaning on the outer side of the product, the sand beam can be quickly introduced into the inside of the sandblasting disc assembly 2 along the feeding pipe 22, the first feeding branch pipe 23 and the second feeding branch pipe 24 provided inside the sandblasting disc assembly 2 for rapid ejection and use of the sand beam. After the workpiece to be sandblasted is introduced from the bottom of the sandblasting disc assembly 2, the sand beam can be quickly ejected along the first type of sandblasting pipes T1, the second type of sandblasting pipes T2, the third type of sandblasting pipes T3 and the fourth type of sandblasting pipes T4 alternately arranged inside the first type of sandblasting disc P1 and the second type of sandblasting disc P2 to perform the sandblasting cleaning activity on the outer side of the workpiece. The structures of the first type of sandblasting pipes T1 and the third type of sandblasting pipes T3 respectively arranged inside the first type of sandblasting disc P1 and the second type of sandblasting disc P2 are the same, that is, the first included angle X1 formed by the extension directions of the first sandblasting cover 214 and the first feeding branch pipe 211 is the same as the third included angle X3 between the third sandblasting cover 233 and the extension direction of the third feeding branch pipe 231, so that the first type of sandblasting pipes T1 and the third type of sandblasting pipes T3 can achieve sandblasting cooperation in the same inclined direction. The structures of the second type of sandblasting pipes T2 and the fourth type of sandblasting pipes T4 respectively arranged inside the first type of sandblasting disc P1 and the second type of sandblasting disc P2 are the same, and the second included angle X2 formed by the second feeding branch pipe 21a and the second sandblasting cover 214a inside the second type of sandblasting pipes T2 and the fourth type of sandblasting pipes T4 is the same as the fourth included angle X4 formed by the fourth sandblasting cover 232a and the fourth feeding branch pipe 231a, so that the sandblasting inclined directions of the second type of sandblasting pipes T2 and the fourth type of sandblasting pipes T4 are the same. Thus, a synchronous mirror cross-direction sandblasting cleaning operation can be realized, and the convex structure of the convex workpiece (the workpiece with a convex structure) can be fully sandblasted, so that each side of the convex workpiece can be fully contacted with the sand beam. In this way, the sandblasting disc assembly can perform comprehensive sandblasting on the convex part or the unprocessable part, so that the sand beam can evenly hit each surface of the product, obtaining a uniform surface treatment effect, and at the same time, it can be processed once, which can greatly save costs.

[0047] Further, the sandblasting direction of the first type of sandblasting disc P1 is symmetric about the vertical plane with the sandblasting direction of the second type of sandblasting disc P2, and the vertical plane is perpendicular to the front-back direction. In this way, under the symmetric cooperation of the sandblasting direction of the first type of sandblasting disc P1 and the sandblasting direction of the second type of sandblasting disc P2 about the vertical plane, the first type of sandblasting disc P1 and the second type of sandblasting disc P2 can achieve synchronous sandblasting cooperation in the mirror cross direction to perform efficient sandblasting cleaning on the convex workpiece.

[0048] Further, the material feeding pipe 22 extends in the left-right direction, and both the first material feeding branch pipe 23 and the second material feeding branch pipe 24 extend in the front-back direction. In this way, under the cooperation of the material feeding of the material feeding pipe 22, the sand beam can quickly flow into the first type of sandblasting pipe T1 (or the second type of sandblasting pipe T2, or the third type of sandblasting pipe T3, or the fourth type of sandblasting pipe T4) along the first material feeding branch pipe 23 and the second material feeding branch pipe 24 that are connected to the left and right sides of the material feeding pipe 22, ensuring the rapid ejection of the sand beam during the subsequent sandblasting cleaning process.
