Description

Technical Field

[0001] The present application relates to the technical field of shot blasting machines, and more specifically, to a through-type shot blasting cleaning machine with high conveying efficiency. Background Art

[0002] A through-type shot blasting machine is a mechanical device used to clean and strengthen the surface of metal workpieces. It primarily consists of a shot blaster, a cleaning chamber, a conveyor system, a shot circulation system, and a dust removal system. Its operating principle is to use the shot blaster to project shots at high speed onto the surface of a workpiece, which continuously passes through the cleaning chamber on a conveyor system. The impact of the shots removes impurities such as scale, rust, oil, and old coatings from the workpiece surface. It also imparts a certain degree of roughness and residual compressive stress to the workpiece surface, enhancing its fatigue resistance and other properties to meet subsequent processing or use requirements. It is widely used for surface treatment of various workpieces in numerous industrial fields, including casting, forging, machining, and automotive manufacturing.

[0003] After searching, patent number CN217751042U discloses a through-type shot blasting machine, which includes a processing table, a shot blasting machine, a conveyor roller, and a conveying auxiliary mechanism. The shot blasting machine is fixedly mounted on the processing table, and the processing table is provided with a groove. Two conveyor rollers are both rotatably connected in the groove. The two conveyor rollers are connected to the same conveyor belt. A servo motor is fixedly mounted on one side of the processing table, and the output shaft of the servo motor is fixedly connected to the conveyor roller. The conveying auxiliary mechanism is arranged on the processing table. The utility model has the following advantages and effects: the shot blasting machine of the utility model has good stability when conveying workpieces, the workpieces are not easily tilted during the conveying process, the conveying efficiency is high, and the workpieces can be kept in a horizontal position when entering the shot blasting machine for processing.

[0004] Although the above patent allows the workpiece to maintain a horizontal position when entering the shot blasting machine for processing, the above patent only corrects the workpiece before it enters the shot blasting machine. When the workpiece enters the shot blasting machine for cleaning, the workpiece will be further offset due to the impact of the projectile. As a result, some areas that should have been cleaned cannot fully receive the impact of the projectile due to the offset, resulting in incomplete cleaning, residual oxide scale, rust and other impurities, affecting the subsequent processing quality and the appearance of the workpiece. The offset workpiece may collide with other components inside the shot blasting machine, which will not only scratch the surface of the workpiece and affect its accuracy and integrity, but also damage the components of the shot blasting machine, increase the maintenance cost and downtime of the equipment, and reduce production efficiency.

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; it is obvious that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0028] Reference Figure 1-Figure 5 A through-type shot blasting machine with high conveying efficiency includes a machine body 1 and a conveyor belt 2. The conveyor belt 2 is located on one side of the machine body 1. A positioning component is provided on one side of the conveyor belt 2. The positioning component is located inside the machine body 1.

[0029] The positioning assembly includes a driving unit and a correction unit. The driving unit includes a handle 12. The correction unit includes a guide plate 5 and an extension plate 6. The handle 12 is used to drive the guide plate 5 to adjust the angle and the correction position.

[0030] Reference Figure 1-Figure 5 , both sides of the conveyor belt 2 are provided with fixed plates 3, and the two fixed plates 3 are fixedly installed on both sides of the inner wall of the body 1. The tops of the two fixed plates 3 are provided with long rods 4, and a cavity 7 is opened on one side of the interior of each long rod 4. The interior of each cavity 7 is rotatably connected to a second rotating shaft 10, and the interior of each second rotating shaft 10 is connected to a worm 11. One side of each second rotating shaft 10 passes through one side of the corresponding long rod 4 and is fixedly connected to one side of the corresponding handle 12. One side of each long rod 4 is rotatably connected to a first rotating shaft 8, and the outer wall of the first rotating shaft 8 is fixedly connected to a worm. Wheel 9, one side of each guide plate 5 is fixedly connected to the outer wall of the corresponding first rotating shaft 8, each worm wheel 9 is respectively engaged with the corresponding worm 11, one end of the guide plate 5 is rotatably connected to one end of the corresponding extension plate 6, and a fixed seat 13 is provided on one side of each long rod 4 and the extension plate 6. A plurality of first connecting rods 14 and second connecting rods 15 are provided between each long rod 4 and the corresponding extension plate 6, and each first connecting rod 14 is rotatably connected to the corresponding second connecting rod 15, and one end of each first connecting rod 14 and second connecting rod 15 is respectively rotatably connected to the corresponding fixed seat 13.

[0031] The positioning assembly can correct the workpiece in time, and the spacing between the guide plates 5 on both sides can also be adjusted according to different workpieces. The specific operation method is that when the angle of the guide plate 5 needs to be adjusted according to different workpieces, first rotate the handle 12, and the handle 12 drives the second rotating shaft 10 to rotate in the cavity 7 of the long rod 4. Since the worm 11 in the second rotating shaft 10 is engaged with the worm gear 9 on the first rotating shaft 8, the rotation of the second rotating shaft 10 will drive the worm gear 9 to rotate, and then drive the first rotating shaft 8 to rotate. Because the guide plate 5 is fixedly connected to the outer wall of the first rotating shaft 8, when the first rotating shaft 8 rotates, the guide plate 5 will rotate around the axis of the first rotating shaft 8, thereby realizing the adjustment of the angle of the guide plate 5. In this way, the angle of the guide plate 5 can be adjusted according to the posture of the workpiece when entering the shot blasting machine, so that the guide plate 5 can better guide the workpiece and ensure that the workpiece is in the correct position when entering the shot blasting machine.

[0032] When the angle of the guide plate 5 changes, since the long rod 4 and the extension plate 6 are connected by multiple first connecting rods 14 and second connecting rods 15 that are rotatably connected to each other, and one end of these connecting rods is rotatably connected to the fixed seat 13, when the angle of the guide plate 5 changes, the corresponding extension plate 6 will change position, and the angle of the first connecting rod 14 and the second connecting rod 15 will change accordingly, thereby realizing the adjustment of the spacing between the guide plates 5 on both sides. In this way, the spacing can be adjusted according to the width of different workpieces, ensuring that workpieces of different sizes can be accurately positioned and corrected during the transportation process, thereby ensuring the smooth progress of the shot blasting cleaning process.

[0033] By means of the guide plate 5 and the extension plate 6 in the positioning assembly, workpieces of different shapes and sizes can be precisely positioned. When the workpiece enters the shot blasting machine, since the angle of the guide plate 5 can be adjusted to adapt to the posture of the workpiece entering, the workpiece can be guided accurately into the correct position on the conveyor belt 2, avoiding positional displacement or collision of the workpiece at the entrance. During the shot blasting cleaning process, this precise positioning helps to ensure that the workpiece is always in the appropriate position to be cleaned by the shot, and prevents insufficient or excessive cleaning of some areas due to improper positioning. At the same time, the positioning assembly can accurately locate and correct deviations in a timely manner, and the conveying process of the workpiece on the conveyor belt 2 is smoother. The conveyor belt 2 will not be blocked or the workpiece position needs to be frequently stopped to adjust due to the confusion of the workpiece position. This ensures that the workpiece can be continuously and stably cleaned by the shot blasting machine, thereby improving the conveying efficiency of the entire shot blasting cleaning process and reducing production time and cost.

[0034] Reference Figure 5 A slot 16 is provided on one side of each guide plate 5 and extension plate 6. A plurality of rollers 17 are rotatably connected to the interior of each slot 16. The outer wall of each roller 17 is set to a smooth surface.

[0035] The roller 17 can reduce the friction between the workpiece and the guide plate 5 and the extension plate 6, which can effectively prevent the surface of the workpiece from being scratched or worn, and ensure that the surface quality of the workpiece is not damaged during the positioning and transportation process. When the workpiece is offset and needs to be corrected, the rolling of the roller 17 can make it easier to guide the workpiece back to the correct position, further enhancing the adaptability of the positioning component to different workpieces.

[0036] Working principle: When it is necessary to adjust the angle of the guide plate 5 according to different workpieces, first rotate the handle 12. The handle 12 drives the second rotating shaft 10 to rotate in the cavity 7 of the long rod 4. Since the worm 11 in the second rotating shaft 10 is engaged with the worm gear 9 on the first rotating shaft 8, the rotation of the second rotating shaft 10 will drive the worm gear 9 to rotate, and then drive the first rotating shaft 8 to rotate. Because the guide plate 5 is fixedly connected to the outer wall of the first rotating shaft 8, when the first rotating shaft 8 rotates, the guide plate 5 will rotate around the axis of the first rotating shaft 8, thereby realizing the adjustment of the angle of the guide plate 5. In this way, the angle of the guide plate 5 can be adjusted according to the posture of the workpiece when entering the shot blasting machine, so that the guide plate 5 can better guide the workpiece, ensuring that the workpiece is in the correct position when entering the shot blasting machine.

[0037] When the angle of the guide plate 5 changes, since the long rod 4 and the extension plate 6 are connected by multiple first connecting rods 14 and second connecting rods 15 that are rotatably connected to each other, and one end of these connecting rods is rotatably connected to the fixed seat 13, when the angle of the guide plate 5 changes, the corresponding extension plate 6 will change position, and the angle of the first connecting rod 14 and the second connecting rod 15 will change accordingly, thereby realizing the adjustment of the spacing between the guide plates 5 on both sides. In this way, the spacing can be adjusted according to the width of different workpieces, ensuring that workpieces of different sizes can be accurately positioned and corrected during the transportation process, thereby ensuring the smooth progress of the shot blasting cleaning process.

[0038] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
