Description

Technical Field

[0001] The utility model relates to the technical field of shot blasting machines, in particular to an environmentally friendly catenary-through reinforced shot blasting machine. Background Art

[0002] Catenary-type shot blasting machines are a common type of surface treatment equipment used for cleaning, rust removal, and surface treatment of various parts and workpieces. They are widely used in metal manufacturing, the automotive industry, aerospace, casting, welding, and other fields. The machine is equipped with a high-speed rotating shot blast jet (usually steel shot) that shoots shot at the workpiece surface at high speed. The impact of the shot blast removes oxide layers, grease, rust, dirt, and other substances from the workpiece surface, achieving the desired cleaning and rust removal effect.

[0003] After searching, the patent publication number CN221111357U provides an environmentally friendly catenary through-type reinforced shot blasting cleaning machine, including a shot blasting box, the top surface of the shot blasting box is installed with a catenary guide rail through a bracket, the bottom surface of the catenary guide rail is slidably connected to a plurality of sliders, the bottom surfaces of the plurality of sliders are provided with a hanging rod, and the top surface of the shot blasting box is provided with a guide opening. The hanging rod and the slider can be limited by a limiting assembly, so that the hanging rod can be fixed when it is outside the shot blasting box, which is convenient for the staff to hang the workpiece and makes the workpiece more stable when moving. The hanging rod can be rotated when entering the shot blasting box, which is convenient for processing the workpiece. Under the action of the material blocking assembly, the through opening and the guide opening can be blocked to prevent the debris in the shot blasting box from being ejected. At the same time, the counterweight block at the bottom of the covering cloth can reduce the covering cloth from being hooked on the hanging hook, thereby increasing the practicality of the device.

[0004] Based on the above search and in conjunction with existing technologies, it was discovered that in existing shot blasting machines similar to those disclosed above, a significant amount of dust is generated during operation when the projectiles collide with the workpiece surface. When the machine opens to allow the chain to enter the inner cavity, the internal dust is released into the outside air, polluting the working environment. Therefore, an environmentally friendly, chain-passing reinforced shot blasting machine is proposed to address this issue. Utility Model Content

[0012] The end portion of the limiting push plate close to its moving direction is set as a sloped edge, and the width of the limiting push plate is greater than the width of the catenary assembly. When the limiting push plate enters and exits the inside of the cleaning machine body, the first dustproof plate and the second dustproof plate are opened under the action of the sloped edge of the limiting push plate, and are reset when separated from the limiting push plate, sealing the inlet and outlet of the cleaning machine body.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example: Reference Figure 1-4The environmentally friendly catenary-through reinforced shot blasting cleaning machine shown includes a cleaning machine body 1 with a shot blaster 2 installed on the top, and an annular track 4 installed on the top of a support frame 3 and passing through the cleaning cavity inside the cleaning machine body 1. The annular track 4 is equidistantly and slidingly installed with multiple catenary assemblies 5 along its length. The annular track 4 and the catenary assemblies 5 adopt a conventional sliding fit method in the prior art, and a conventional driving element is used to drive the catenary assembly 5 to slide cyclically along the annular track 4.

[0027] Among them, a first dust-proof plate 6 is installed at the inlet and outlet of the cleaning machine body 1, and a second dust-proof plate 7 is provided on the side where the two first dust-proof plates 6 are close to each other, and the second dust-proof plate 7 is installed on the inner side of the cleaning machine body 1. The distance between the first dust-proof plate 6 and the second dust-proof plate 7 on the same side of the cleaning machine body 1 is greater than the horizontal width of the catenary assembly 5, and at the same time greater than the distance between two adjacent catenary assemblies 5.

[0028] Based on the coordinated arrangement of the above structure, a transition zone is formed between the first dust-proof plate 6 and the second dust-proof plate 7 on the same side of the cleaning machine body 1. When the catenary assembly 5 enters the cleaning machine body 1, the first dust-proof plate 6 at the entrance of the cleaning machine body 1 is first opened. As the catenary assembly 5 continues to slide, the first dust-proof plate 6 is closed. Before that, the second dust-proof plate 7 on the same side remains sealed, and the dust inside the cleaning chamber will not overflow, but fall to the bottom of the cleaning machine body 1 under the action of its own gravity. Then the catenary assembly 5 continues to slide, the second dust-proof plate 7 is opened, and the catenary assembly 5 The workpiece is carried into the cleaning chamber until it is sealed by the second dustproof plate 7, and the workpiece is cleaned; similarly, when the catenary assembly 5 leaves the cleaning machine body 1, the second dustproof plate 7 at the outlet of the cleaning machine body 1 is first opened, and as the catenary assembly 5 continues to slide, the second dustproof plate 7 is closed. Before this, the first dustproof plate 6 on the same side remains sealed, and the dust inside the cleaning chamber will not overflow, but fall to the bottom of the cleaning machine body 1 under its own gravity. Then the catenary assembly 5 continues to slide, the first dustproof plate 6 is opened, and the catenary assembly 5 carries the workpiece away until it is sealed by the first dustproof plate 6.

[0029] It can be seen that through the coordinated arrangement of the above-mentioned first dustproof plate 6 and the second dustproof plate 7, it is not easy for the catenary assembly 5 to cause dust overflow inside the cleaning machine body 1 during the process of entering and exiting the inside of the cleaning machine body 1, thereby improving the working environment.

[0030] Among them, the first dustproof plate 6 is slidably installed at the inlet and outlet of the cleaning machine body 1 perpendicular to the length direction of the circular track 4, and the first dustproof plate 6 is elastically connected to the cleaning machine body 1, and the second dustproof plate 7 is slidably installed on the inner side of the cleaning machine body 1 perpendicular to the length direction of the circular track 4, and the second dustproof plate 7 is elastically connected to the cleaning machine body 1. The above-mentioned elastic connection can be achieved by conventional elastic connecting parts in the prior art, such as compression springs, so that the first dustproof plate 6 and the second dustproof plate 7 can automatically reset to the inlet and outlet of the sealed cleaning machine body 1 when separated from the catenary assembly 5.

[0031] Among them, the catenary assembly 5 includes a hanging rod 51, a limiting support plate 52 and a plurality of hanging hook columns 53. The limiting support plate 52 is slidably installed on the lower end of the circular track 4, the hanging rod 51 is installed on the lower end of the limiting support plate 52, and a plurality of hanging hook columns 53 are evenly fixed on the side ends of the hanging rod 51. The end of the limiting support plate 52 on one side close to its moving direction is set to a slope edge. The width of the limiting support plate 52 is greater than the width of the catenary assembly 5. When the limiting support plate 52 enters and exits the inner side of the cleaning machine body 1, the first dustproof plate 6 and the second dustproof plate 7 are opened under the action of the slope edge of the limiting support plate 52, and reset when separated from the limiting support plate 52, sealing the inlet and outlet of the cleaning machine body 1.

[0032] Among them, the free end of the suspension hook column 53 is set obliquely upward, and an anti-slip block 54 is installed on the side of the free end of the suspension hook column 53 close to the suspension rod 51. The anti-slip block 54 makes it difficult for the workpiece hung on the suspension hook column 53 to fall off the suspension hook column 53.

[0033] Among them, the hanging rod 51 is rotatably connected to the limiting plate 52, and a first friction ring 55 is coaxially fixed to the top of the hanging rod 51. A first friction track 8 in contact with the first friction ring 55 is horizontally installed on the inner side of the cleaning machine body 1, and the first friction track 8 is located between the two second dust-proof plates 7. In the process of the catenary assembly 5 passing through the cleaning cavity inside the cleaning machine body 1, the first friction ring 55 is subjected to the friction of the first friction track 8, so that the hanging hook column 53 rotates around the axis of the hanging rod 51 with the workpiece, and the cleaning is more comprehensive.

[0034] Among them, a second friction ring 56 is coaxially fixed to the top of the suspension rod 51, and a second friction track 9 in contact with the second friction ring 56 is horizontally installed on the inner side of the cleaning machine body 1, and the second friction track 9 is located between the second dust-proof plate 7 and the first dust-proof plate 6 near the discharge port of the cleaning machine body 1. The diameter of the second friction track 9 is smaller than the diameter of the first friction track 8. After cleaning is completed, when the catenary assembly 5 slides between the second dust-proof plate 7 and the first dust-proof plate 6 at the discharge port of the cleaning machine body 1, the second friction ring 56 is subjected to the friction of the second friction track 9, so that the suspension hook column 53 carries the workpiece to accelerate around the axis of the suspension rod 51, so that the projectile and the cleaned debris can be thrown out under the action of centrifugal force, and will not leave the cleaning machine body 1 with the workpiece.

[0035] The working principle of the present invention is as follows: during the process of the catenary assembly 5 entering the cleaning machine body 1, the limiting push plate 52 is used to open the first dust-proof plate 6 at the entrance of the cleaning machine body 1. As the catenary assembly 5 continues to slide, the first dust-proof plate 6 is closed. Before that, the second dust-proof plate 7 on the same side remains in a sealed state, and the dust inside the cleaning chamber will not overflow, but fall to the bottom of the cleaning machine body 1 under the action of its own gravity. Then the catenary assembly 5 continues to slide, the second dust-proof plate 7 is opened, and the catenary assembly 5 brings the workpiece into the cleaning chamber until the second dust-proof plate 7 is sealed, and the workpiece is cleaned. During the cleaning process, the first friction ring 55 is subjected to the friction of the first friction track 8, so that the suspension hook column 53 rotates around the axis of the suspension rod 51 with the workpiece, and the cleaning is more comprehensive. Similarly, the catenary assembly In the process of the component 5 leaving the cleaning machine body 1, the second dust-proof plate 7 at the outlet of the cleaning machine body 1 is first opened, and as the catenary assembly 5 continues to slide, the second dust-proof plate 7 is closed. Before this, the first dust-proof plate 6 on the same side remains sealed, and the dust inside the cleaning chamber will not overflow outward, but fall to the bottom of the cleaning machine body 1 under the action of its own gravity. In this process, the second friction ring 56 is subjected to the friction of the second friction track 9, so that the suspension hook column 53 accelerates the rotation around the axis of the suspension rod 51 with the workpiece, so that the projectile and the cleaned debris can be thrown out under the action of centrifugal force, and will not leave the cleaning machine body 1 with the workpiece. Then the catenary assembly 5 continues to slide, the first dust-proof plate 6 opens, and the catenary assembly 5 takes the workpiece away to the first dust-proof plate 6 for sealing.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
