Description

Technical Field

[0001] The utility model relates to the technical field of shot blasting machines, in particular to a shot blasting machine with low noise. Background Art

[0002] Shot blasting machine is a mechanical device used for metal surface treatment. It projects small spherical particles (called shots or abrasives) onto the surface of the workpiece at high speed to achieve the purpose of cleaning, strengthening or shaping.

[0003] The patent with the current announcement number CN216228848U discloses a shot blasting machine for steel structures, including a frame body, a conveyor roller frame fixedly installed on the inner wall of the frame body, two sets of first shot blasting machines of the same size fixedly installed on the upper and lower side walls of the frame body, two sets of second shot blasting machines of the same size fixedly installed on the left and right side walls of the frame body, and two support frames of the same size fixedly installed inside the frame body. The shot blasting machine transports the steel structure through the conveyor roller frame, and the second shot blasting machine and the first shot blasting machine are located in the gap between the conveyor roller frame. When the steel structure reaches directly below the photoelectric switch, the second shot blasting machine and the first shot blasting machine are automatically turned on, which can avoid the waste of pellets and energy caused by the long-term operation of the second shot blasting machine and the first shot blasting machine. In addition, the second shot blasting machine and the first shot blasting machine can perform all-round shot blasting on the four surfaces of the steel structure, thereby improving the efficiency of the device in shot blasting the steel structure.

[0004] However, the above-mentioned shot blasting machine still has the following problems in actual use:

[0005] When the shot blasting machine processes the surface of the steel entering the interior, the ejected pellets are mostly sprayed from top to bottom or from bottom to top, so it can only process the upper and lower sides of the steel. If the steel is thicker (such as H-shaped steel), the treatment effect on the side of the steel will be relatively poor. The existing shot blasting machine does not have the function of flipping the steel, which is very inconvenient. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] See also Figure 1-Figure 3 , a shot blasting machine with low noise includes two shot blasting boxes 1, a turning box 2 is fixedly connected between the two shot blasting boxes 1, the upper surface of the outer wall of the turning box 2 is fixedly connected with a lifting mechanism, the output end of the lifting mechanism passes through the turning box 2 and is connected with a lifting plate 4, the side wall of the lifting plate 4 is slidably connected to the inner wall of the turning box 2, the upper surface of the lifting plate 4 is fixedly connected with a power mechanism and two support plates 14, the output end of the power mechanism is connected with a linkage assembly, the other end of the linkage assembly is connected to two winding assemblies, the two winding assemblies are respectively connected to the two support plates 14, and the two winding assemblies are also respectively connected to pull ropes 10, the other end of the two pull ropes 10 passes through one end of the lifting plate 4 and is fixedly connected to the bottom surface of the other end of the lifting plate 4, and the inner wall of the turning box 2 is connected with several rolling mechanisms.

[0023] The shot blasting machine with low noise in the present invention is similar in structure to the existing shot blasting machine, such as the shot blasting machine for steel structure disclosed in the patent with announcement number CN216228848U. Figures 1 to 3 As shown, when the shot blasting machine with low noise in the present invention performs surface treatment on thicker steel through the shot blasting box 1, the steel is first input from one side of one of the shot blasting boxes 1, and then the shot blasting mechanism inside the shot blasting box 1 (this is the existing technology, so it will not be described in detail) will process the upper and lower sides of the steel, and then the steel continues to move. When the steel moves to the inside of the flip box 2, the two ends of the steel are just above the two pull ropes 10. At this time, the winding mechanism is started and the pull rope 10 is gradually tightened from one end. When the pull rope 10 contacts the bottom surface of the steel, it will rise with the steel, and in the process of rising, because one end of the pull rope 10 is winding and the other end remains stationary, the steel can be tilted toward the stationary side until it rotates 90°, and then the lifting mechanism is started. The lifting mechanism controls the lifting plate 4 to descend, and the flipped steel is placed on several rolling mechanisms again, and then the pull rope 10 is released to return it to its original state, waiting for subsequent steel to enter, and repeat the above process. After the steel is placed on the rolling mechanism, the rolling mechanism is started to transport the turned steel to the inside of the next shot blasting box 1 for processing, so that all four sides of the steel can be processed, resulting in a better processing effect.

[0024] like Figure 1-Figure 3 As shown, the lifting mechanism includes a hydraulic rod 3 and a lifting rod 15. The outer wall of the hydraulic rod 3 is fixedly connected to the upper surface of the outer wall of the flip box 2, the output end of the hydraulic rod 3 is fixedly connected to the upper end of the lifting rod 15, and the lower end of the lifting rod 15 passes through the flip box 2 and is fixedly connected to the upper surface of the lifting plate 4.

[0025] More specifically, when it is necessary to control the lifting plate 4 to rise and fall, it is only necessary to open the hydraulic rod 3, and the output end of the hydraulic rod 3 can be extended outward or retracted, thereby driving the lifting rod 15 to rise and fall, thereby driving the lifting plate 4 to rise and fall.

[0026] like Figure 1-Figure 3 As shown, the power mechanism includes a motor base 5 and a winding motor 6. The lower end of the motor base 5 is fixedly connected to the upper surface of the lifting plate 4, the upper end of the motor base 5 is fixedly connected to the outer wall of the winding motor 6, and the output shaft of the winding motor 6 is connected to the linkage assembly.

[0027] More specifically, when it is necessary to control the winding assembly to retract and release the pull rope 10, it is only necessary to turn on the winding motor 6. The output shaft of the winding motor 6 can drive the linkage assembly to rotate forward and reverse, thereby driving the winding assembly to rotate forward and reverse, and then the pull rope 10 can be retracted and released.

[0028] like Figure 1-Figure 3As shown, the linkage assembly includes a chain 11 and two sprockets 13, one side of the two sprockets 13 is connected to the two winding assemblies respectively, the other side of one of the sprockets 13 is fixedly connected to the output shaft of the winding motor 6, and the chain 11 is sleeved on the outside of the two sprockets 13 and meshes with the two sprockets 13.

[0029] More specifically, when the output shaft of the winding motor 6 rotates, the sprocket 13 connected to the output shaft of the winding motor 6 rotates. When this sprocket 13 rotates, the chain 11 can drive another sprocket 13 to rotate, so that the two winding components can be controlled to be retracted and released at the same time through the two sprockets 13, and the steel can be retracted and released from both ends at the same time.

[0030] like Figure 1-Figure 3 As shown, the winding assembly includes a transmission rod 7 and a winding roller 8, one end of the transmission rod 7 is fixedly connected to the side of the sprocket 13 away from the winding motor 6, the other end of the transmission rod 7 passes through the support plate 14 and the winding roller 8, the outer wall of the transmission rod 7 is rotatably connected to the inner wall of the support plate 14, the outer wall of the transmission rod 7 is fixedly connected to the inner wall of the winding roller 8, and the end of the pull rope 10 away from the lifting plate 4 is fixedly connected to the outer wall of the winding roller 8.

[0031] More specifically, when the sprocket 13 rotates, the transmission rod 7 can be mobilized to rotate inside the support plate 14. After the support plate 14 rotates, the external winding roller 8 can be driven to rotate. As the winding roller 8 rotates, the retraction and extension of the pull rope 10 can be controlled.

[0032] like Figure 1-Figure 3 As shown, side plates 9 are sleeved and fixedly connected to the outer walls of both ends of the transmission rod 7.

[0033] More specifically, by providing the side plate 9 , the pull cord 10 can be prevented from falling off from one side of the winding roller 8 .

[0034] like Figure 1-Figure 3 As shown, the rolling mechanism includes a rolling motor 16 and a roller 12. The outer wall of the rolling motor 16 is fixedly connected to one side of the outer wall of the flip box 2. The output shaft of the rolling motor 16 is fixedly connected to one end of the roller 12. The other end of the roller 12 passes through the side wall of the flip box 2 and is rotatably connected to the inner wall of the flip box 2.

[0035] More specifically, when the steel moves into the flip box 2 and is lifted by the two pull ropes 10 and rotated 90°, the roller 12 can be driven to rotate by the rolling motor 16 to provide a thrust to the steel, making it easier for the steel to enter the next shot blasting box 1.

[0036] like Figure 1-Figure 3 As shown, the inner walls of the turnover box 2 and the two shot blasting boxes 1 are fixedly connected with sound insulation boards.

[0037] More specifically, by providing a sound insulation board, the impact of the noise generated during the internal operation of the overturning box 2 and the two shot blasting boxes 1 on the outside can be reduced.

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