Description

Technical Field

[0001] The utility model relates to the technical field of shot blasting machines, in particular to a roller protection structure for a shot blasting machine. Background Art

[0002] Shot blasting is a processing technology that uses a shot blaster to throw steel grit and steel shot at high speed onto the surface of a material object. Compared with other surface treatment technologies, it is faster and more effective, and can be used in the casting process after partial retention or stamping. Shot blasting equipment is used in the foundry industry to remove sand and oxide scale from the surface of cast steel and cast iron parts.

[0003] The existing Chinese utility model patent with reference announcement number CN211940494U discloses a shot blasting machine, which belongs to the technical field of concrete product processing, including a shot blasting machine body, a shot blasting head assembly, a feed box, a power mechanism and a conveyor; a working chamber is arranged in the shot blasting machine body; openings communicating with the working chamber are arranged at both ends of the shot blasting machine body; the shot blasting head assembly is fixedly arranged on one side of the shot blasting machine body and communicated with the working chamber; the feed box is located above the shot blasting head assembly and communicated with the shot blasting head assembly; a rotating material gate for changing the feed flow rate is arranged in the feed box; the power mechanism is arranged on one side of the feed box and is used to drive the rotating material gate to rotate; the conveyor is arranged in the working chamber and is used to transport products. The shot blasting machine provided by the utility model drives the rotating material gate to rotate in the feed box by means of the power mechanism, changes the flow area of ​​the feed box, changes the high-speed shot material ejected by the shot blasting head assembly, and then changes the force, speed, angle, etc. of the shot material hitting the surface of the product, so as to achieve the purpose of changing the surface processing effect of the product.

[0004] Since the shot blasting machine causes fine particles to hit the conveying rollers that convey the workpiece during operation, and the existing conveying rollers have no protective structure and the movement path of the particles is not restricted, some particles will directly hit the part of the conveying roller that is not directly below the exit of the shot blasting machine. The conveying roller will cause surface wear under the impact of the particles, thereby reducing its service life. In addition, after hitting the workpiece, the fine particles will diffuse in all directions, which may prevent the fine particles from falling into the receiving structure and cause waste of particles. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a shot blasting machine roller protection structure, which has the advantages of reducing the wear of the conveying roller and avoiding the waste of fine particles, thereby solving the above-mentioned technical problems.

[0007] (II) Technical solution

[0008] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] A shot blasting machine roller protection structure comprises: a support frame, a limit position frame is fixedly installed on the top of the support frame, a limit position block is fixedly installed inside the support frame, a bearing is embedded inside the support frame, and a connecting shaft is inserted and installed inside the bearing, a baffle is fixedly installed on the outside of the connecting shaft, a connecting rod is movably installed inside the support frame, and a conveying roller is inserted and installed on the front side of the connecting rod, a connecting plate is fixedly installed inside the support frame, and a silicone plate is fixedly installed below the connecting plate, a receiving frame is inserted and installed below the support frame, and a conveying plate is fixedly installed inside the receiving frame; the support frame can support the connecting shaft.

[0010] As the preferred technical solution of the utility model, the support frame is in a "concave" shaped structure, and the limit block is installed on the front and rear sides of the top of the inner wall of the limit block in a mirror-symmetrical manner with the center of the support frame as the reference; the limit frame can limit the falling area of ​​the particles.

[0011] As a preferred technical solution of the utility model, a cylindrical opening structure which is symmetrical front and back with the support frame as a reference is provided on the front and rear side facades of the support frame, and the aperture of the cylindrical opening structure of the support frame is consistent with the outer diameter of the bearing, and the bearing is embedded and installed at the front and rear ends of each opening structure of the support frame; the bearing can reduce the friction between the connecting shaft and the support frame when it rotates.

[0012] As a preferred technical solution of the utility model, the connecting shaft is rotatably connected to the support frame through a bearing, and the baffle is installed in a ring shape on the outside of the connecting shaft with the axis of the connecting shaft as a reference; the baffle can limit the range of falling particles.

[0013] As a preferred technical solution of the utility model, the connecting rod is symmetrically installed on the front and rear sides of the conveying roller with the center of the conveying roller as the reference, the conveying rollers are equidistantly installed between the conveying rollers in an interlaced manner, and a rotational connection is formed between the conveying rollers and the connecting rod; the connecting rod can fix the position of the conveying roller.

[0014] As the preferred technical solution of the utility model, the connecting plate is installed inside the support frame symmetrically with the center of the support frame as the reference, and the silicone plate is installed below the connecting plate symmetrically with the center of the connecting plate as the reference; the connecting plate can fix the relative position between the silicone plate and the support frame.

[0015] As the preferred technical solution of the utility model, the top surface of the receiving frame is a slope structure, the conveying plate is obliquely installed at the bottom end of the receiving frame, the inclination angle of the conveying plate is fifteen degrees, and the bottom ends of the support frame and the receiving frame are provided with an opening structure equal to the length of the conveying plate; the receiving frame can receive particles falling from the area between the conveying rollers.

[0016] Compared with the prior art, the utility model provides a shot blasting machine roller protection structure, which has the following beneficial effects:

[0017] 1. The utility model sets a baffle, which is annularly installed on the outside of the connecting shaft. Since the connecting shaft is rotatably connected to the support frame through the bearing, and the connecting shaft is symmetrically installed inside the support frame with the center of the support frame as the reference, the baffle can block particles that cannot hit the workpiece, and prevent the particles from hitting the conveying roller that is not directly below the shot blasting machine outlet, thereby protecting the conveying roller. After the baffle takes on a certain mass of particles, the center of gravity of the baffle and the connecting shaft will change, and the connecting shaft will be driven by the baffle to rotate under the action of the gravity of the particles. When the baffle rotates a certain angle, the particles above the baffle will slide off the surface of the baffle under the action of gravity.

[0018] 2. The utility model sets a connecting plate, which can keep the relative position between the silicone plate and the support frame fixed. Since the silicone plate is symmetrically installed under the connecting plate with the center of the connecting plate as a reference, when the conveyor roller conveys the workpiece and contacts the silicone plate, the silicone plate will deform to facilitate the workpiece. When particles hit the workpiece and scatter, the silicone plate can intercept the scattered particles, so that the falling process of the particles is located directly above the receiving frame, thereby avoiding the recycling of particles and preventing the particles from being scattered to areas outside the receiving frame, which are difficult to collect and cause waste.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] See also Figure 1 — Figure 4 In this embodiment, a shot blasting machine roller protection structure includes: a support frame 1, a limit frame 11 is fixedly installed on the top of the support frame 1, a limit block 12 is fixedly installed inside the support frame 1, a bearing 13 is embedded in the support frame 1, and a connecting shaft 14 is inserted and installed inside the bearing 13, and a baffle 15 is fixedly installed on the outside of the connecting shaft 14.

[0028] The support frame 1 is in a "concave" shape, and the limit block 12 is installed on the front and rear sides of the top of the inner wall of the limit block 12 in a mirror-symmetrical manner with the center of the support frame 1 as a reference.

[0029] The front and rear facades of the support frame 1 are provided with a cylindrical opening structure which is symmetrical front and back with the support frame 1 as a reference, and the aperture of the cylindrical opening structure of the support frame 1 is consistent with the outer diameter of the bearing 13, and the bearing 13 is embedded and installed at the front and rear ends of each opening structure of the support frame 1.

[0030] The connecting shaft 14 is rotatably connected to the support frame 1 via the bearing 13 , and the baffle 15 is annularly installed on the outer side of the connecting shaft 14 with the axis of the connecting shaft 14 as a reference.

[0031] Specifically, the support frame 1 can support the connecting shaft 14, the limit frame 11 can limit the falling area of ​​the particles, the limit block 12 supports the limit frame 11, the bearing 13 can reduce the friction between the connecting shaft 14 and the support frame 1 when it rotates, so as to facilitate the rotation of the connecting shaft 14, and the baffle 15 can limit the falling range of the particles. After the particles are launched by the shot blasting machine, since the shot blasting machine cannot limit the movement path of the particles, some of the particles will hit the top of the baffle 15 installed in a ring shape on the outside of the connecting shaft 14 during the movement. After the baffle 15 takes on a certain mass of particles, the axis of the baffle 15 and the connecting shaft 14 will change, and the connecting shaft 14 will be driven by the baffle 15 to rotate under the action of the gravity of the particles. When the baffle 15 rotates a certain angle, the particles above the baffle 15 will slide off the surface of the baffle 15 under the action of gravity.

[0032] A connecting rod 16 is movably installed inside the support frame 1, and a conveying roller 17 is inserted into the front side of the connecting rod 16. A connecting plate 18 is fixedly installed inside the support frame 1, and a silicone plate 19 is fixedly installed below the connecting plate 18. A receiving frame 110 is inserted into the bottom of the support frame 1, and a conveying plate 111 is fixedly installed inside the receiving frame 110.

[0033] The connecting rod 16 is symmetrically installed on the front and rear sides of the conveying roller 17 with the center of the conveying roller 17 as the reference. The conveying rollers 17 are installed equidistantly between the conveying rollers 17 in an interlaced manner, and the conveying rollers 17 and the connecting rod 16 are rotationally connected.

[0034] The connecting plate 18 is installed inside the supporting frame 1 symmetrically with the center of the supporting frame 1 as a reference, and the silicone plate 19 is installed below the connecting plate 18 symmetrically with the center of the connecting plate 18 as a reference.

[0035] The top surface of the receiving frame 110 is a slope structure, and the conveying plate 111 is obliquely installed at the bottom end of the receiving frame 110. The inclination angle of the conveying plate 111 is fifteen degrees. The bottom ends of the support frame 1 and the receiving frame 110 are both provided with an opening structure with the same length as the conveying plate 111.

[0036] The connecting rod 16 can fix the position of the conveying roller 17, the conveying roller 17 can drive the workpiece to move, the connecting plate 18 can fix the relative position between the silicone plate 19 and the support frame 1, the silicone plate 19 can block the particles while facilitating the passage of the workpiece to prevent the particles from spreading, the receiving frame 110 can receive the particles falling from the area between the conveying rollers 17, the conveying plate 111 can receive the particles, and because the inclination angle of the conveying plate 111 is fifteen degrees, the particles can slide on the top of the conveying plate 111 under the action of their own gravity, and be discharged through the opening structure at the bottom of the support frame 1 and the receiving frame 110.

[0037] During use, the workpiece will contact the silicone plate 19 driven by the conveying roller 17. When the workpiece contacts the silicone plate 19, the silicone plate 19 will be deformed to facilitate the workpiece to pass through the silicone plate 19 and move to just below the exit of the shot blasting machine. After the particles are launched by the shot blasting machine, since the shot blasting machine cannot limit the movement path of the particles, some of the particles will hit the top of the baffle 15 installed in a ring shape on the outside of the connecting shaft 14 during the movement. After the baffle 15 takes on a certain mass of particles, the axis of the baffle 15 and the connecting shaft 14 will change. The connecting shaft 14 will be driven by the baffle 15 to rotate under the action of the gravity of the particles. When the baffle 15 rotates a certain angle, the particles above the baffle 15 will slide from the surface of the baffle 15 under the action of gravity. The particles that fall partially in the movement path between the baffles 15 will hit the surface of the workpiece, and will be scattered after hitting the workpiece. The scattered particles will be intercepted by the silicone plate 19, thereby avoiding the particles from colliding with other conveying rollers 17 and limiting the direction in which the particles fall. The particles will eventually fall onto the surface of the conveying plate 111 below through the area between the conveying rollers 17 under the action of their own gravity. The receiving frame 110 can receive the particles that fall from the area between the conveying rollers 17, and the conveying plate 111 can receive the particles. Since the inclination angle of the conveying plate 111 is fifteen degrees, the particles can slide on the top of the conveying plate 111 under the action of their own gravity, and be discharged through the opening structure at the bottom of the support frame 1 and the receiving frame 110.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
