Description

Technical Field

[0001] This utility model relates to the field of shot blasting machines, specifically a material separation structure for shot blasting machines. Background Technology

[0002] After material processing is completed, tracked shot blasting machines typically discharge the material directly from the outlet. However, the discharged material often contains shot and rust, severely affecting the quality of material recovery. Therefore, it is necessary to separate the shot and rust from the material. Chinese utility model patent application number 202323095498.8 discloses a feeding mechanism for a shot blasting machine. After the workpiece is polished by the launcher, the falling shot and rust are conveyed to the collection pipe via a feeding conveyor belt. The separation mechanism is then activated, using a permanent magnet to attract the shot to the left side of the distribution box, while the rust is not attracted by the permanent magnet and falls to the right side of the distribution box, thus achieving the purpose of automatic waste separation.

[0003] The aforementioned feeding mechanism can separate rust from shot. However, during use, a defect was found: it only attracts the shot to the distribution box through a permanent magnet at the bottom, but the shot is relatively concentrated during feeding and the downward force is large. It is difficult to attract all the shot with just one permanent magnet, resulting in omissions and incomplete separation of the shot. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a shot blasting machine feeding and separation structure. This structure adopts a rotary separation structure and uses multiple permanent magnets for attraction and separation, effectively solving the problem of incomplete shot separation caused by relying on a single permanent magnet in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a shot blasting machine feeding and separation structure, including a front-opening and rotatable separation component, a rearwardly extending rotating shaft fixedly provided on the rear side of the separation component, the rotating shaft being installed through the top of the support, and a motor reducer for driving the rotating shaft to rotate being provided on the rear side of the support.

[0006] The support is fixed to the base at the bottom. The base is a flat cuboid in shape, and universal wheels with limiting function are fixed at the four corners of the bottom surface.

[0007] A collection box is placed on the base below the separation component.

[0008] As a preferred technical solution, the separation component includes a cylindrical tube with a front opening. A ring-shaped baffle is fixedly provided on the inner surface of the opening of the cylindrical tube, so that a ring-shaped cavity is formed on the inner side of the cylindrical tube. A number of mesh holes are embedded on the side circumference of the cylindrical tube.

[0009] The inner side of the cylindrical tube is inlaid with several arc-shaped grooves at intervals, and the outer surface of the cylindrical tube outside the arc-shaped grooves is fixed with an attraction structure of a detachable permanent magnet.

[0010] The inner side of the cylindrical tube is fitted with a discharge port, and the outer side of the discharge port is provided with a cover. One end of the cover is hinged to the outer side of the cylindrical tube through a hinge shaft, and the other end of the cover is fixedly connected to the cylindrical tube by screws.

[0011] As a preferred technical solution, the attraction structure includes a shell with a bottom opening and a side opening, the bottom surface of the shell is fixed to the outer surface of the cylindrical tube, and a slidable permanent magnet is provided in the shell;

[0012] The upper side of the opening end of the housing is provided with a rubber bolt for limiting the permanent magnet.

[0013] As a preferred technical solution, the collection box is in the shape of a cuboid with an open top, and a first arc-shaped handle is fixed on each of the left and right outer sides.

[0014] As a preferred technical solution, the front end face of the permanent magnet is fixedly provided with a second arc-shaped handle.

[0015] As a preferred technical solution, the arc-shaped groove does not have mesh holes.

[0016] As a preferred technical solution, the annular baffle is fixedly provided with an annular guide plate with front and rear openings on its front side.

[0017] Compared with the prior art, this utility model provides a material separation structure for shot blasting machines, which has the following beneficial effects:

[0018] 1. This utility model includes a cylindrical tube with a front opening as a separating component. A ring-shaped baffle is fixedly provided on the inner surface of the opening of the cylindrical tube, so that a ring-shaped cavity is formed on the inner side of the cylindrical tube. Several mesh holes are embedded on the side circumference of the cylindrical tube, and several arc-shaped grooves are embedded at intervals on the inner side of the cylindrical tube. A detachable permanent magnet attraction structure is fixedly provided on the outer surface of the cylindrical tube outside the arc-shaped groove. In use, the front opening of the device is facing the feed port of the shot blasting machine, and it is pushed forward so that the front opening of the cylindrical tube is connected with the feed port. It is limited by the universal wheel, and then the material slides into the cylindrical tube. The cylindrical tube rotates under the drive of the motor reducer. The permanent magnet on the outside can attract the shot and finally attract and fix the shot in the arc-shaped groove. The shot is located in the arc-shaped groove, which effectively reduces the scraping of the shot when the material slides.

[0019] 2. This utility model features a collection box placed on a base below the separation component. A discharge port is embedded on the inner side of the cylindrical tube, and a cover is provided on the outer side of the discharge port. One end of the cover is hinged to the outer side of the cylindrical tube via a hinge shaft, and the other end of the cover is fixedly connected to the cylindrical tube via screws. In use, rust that slides down through the mesh can be collected in the collection box. After the rust separation is complete, the collection box can be replaced, and the cover can be opened so that the discharge port can be rotated downwards, allowing the material to slide into the collection box through the discharge port. Finally, another collection box is replaced, and the rubber bolts are loosened to pull out the permanent magnets. The projectile loses its attraction and fixing effect and slides into the collection box under the action of gravity. The projectile can contact multiple permanent magnets while rotating, which is conducive to the projectile's full attraction and fixing, thus improving the separation effect.

[0020] 3. This utility model has an annular guide plate with front and rear openings fixed on the front side of the annular baffle. In use, the guide plate can be connected with the feed port of the shot blasting machine, which helps to improve the smoothness of material feeding into the cylindrical tube.

Detailed Implementation

[0028] 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. Example 1

[0029] like Figures 1 to 4 As shown, a shot blasting machine material separation structure includes a front-opening and rotatable separation component 3. A rearwardly extending rotating shaft (not shown) is fixed to the rear side of the separation component 3. The rotating shaft is mounted through the top of a support 2, and a motor reducer 4 (with a control switch on one side) is located on the rear side of the support 2 to drive the rotating shaft. The bottom of the support 2 is fixed to a base 1, which is generally flat and rectangular. Universal wheels 11 with limiting functions are fixed to the four corners of the bottom surface. A collection box 5 is placed on the base 1 below the separation component 3.

[0030] The separating component 3 includes a cylindrical tube 31 with a front opening (which may be made of rigid plastic with embedded steel bars). A ring-shaped baffle 32 is fixedly provided on the inner surface of the opening of the cylindrical tube 31, so that the inner side of the cylindrical tube 31 forms a ring-shaped cavity. Several mesh holes 33 are embedded on the side circumference of the cylindrical tube 31. Several arc-shaped grooves 34 are embedded at intervals on the inner side of the cylindrical tube 31. A detachable permanent magnet attraction structure 35 is fixedly provided on the outer surface of the cylindrical tube 31 outside the arc-shaped grooves 34. A discharge port (not shown, square through hole) is embedded on the inner side of the cylindrical tube 31. A cover 36 is provided on the outer side of the discharge port. One end of the cover 36 is hinged to the outer side of the cylindrical tube 31 through a hinge shaft 361, and the other end of the cover 36 is fixedly connected to the cylindrical tube 31 through a screw 362.

[0031] The attraction structure 35 includes a housing 351 with a bottom opening and a side opening. The bottom surface of the housing 351 is fixed to the outer surface of the cylindrical tube 31. A slidable permanent magnet 352 is provided in the housing 351. A rubber bolt 354 is provided on the upper side of the opening end of the housing 351 to limit the permanent magnet 352.

[0032] The collection box 5 is a rectangular parallelepiped with an opening at the top, and the left and right outer sides are respectively fixed with a first arc-shaped handle 51.

[0033] The front end face of the permanent magnet 352 is fixed with a second arc-shaped handle 353.

[0034] No mesh 33 is provided in the arc-shaped groove 34.

[0035] In use, the front opening of the device faces the feed port of the shot blasting machine, and it is pushed forward so that the front opening of the cylindrical cylinder 31 aligns with the feed port of the shot blasting machine. The universal wheel 11 limits the movement, and then the material slides into the cylindrical cylinder 31. The cylindrical cylinder 31 rotates under the drive of the motor reducer 4. The permanent magnet 352 on the outside can attract the shot and finally attract and fix the shot in the arc-shaped groove 34. The shot is located in the arc-shaped groove 34, which effectively reduces the scraping of the shot when the material slides. Rust that slides through mesh 33 can be collected in collection box 5. After the rust separation is complete, collection box 5 can be replaced and cover 36 can be opened so that the discharge port can be rotated downwards. The material can then slide into collection box 5 through the discharge port. Finally, another collection box 5 can be replaced, and the rubber bolts 354 can be loosened to pull out the permanent magnets 352. The projectiles will lose their attraction and fixation effect and will slide into collection box 5 under the action of gravity. The projectiles can contact multiple permanent magnets 352 while the cylindrical tube 31 is rotating, which is conducive to the full attraction and fixation of the projectiles and improves the separation effect. Example 2

[0036] like Figure 5 As shown, an annular guide plate 6 with front and rear openings is fixed on the front side of the annular baffle 32.

[0037] When in use, the guide plate 6 can be connected to the feed port of the shot blasting machine, which helps to improve the smoothness of material feeding into the cylindrical tube 31.
