Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, specifically a shot blasting machine with graded grinding function. Background Technology

[0002] Shot blasting is a key process in the machinery manufacturing industry for cleaning and strengthening the surface of metal workpieces. It is widely used in processes such as sand removal from castings, rust removal from steel plates, and deburring of gears.

[0003] Reference patent document: Patent Publication No. CN217194760U, Patent Publication Date 2022-08-16, discloses a shot blasting machine with graded grinding function, including a grinding box, a rotary motor fixedly installed at the upper end of the grinding box, a hook fixedly installed at the lower shaft end of the rotary motor, a shot blasting chamber arranged on the left side inside the grinding box, an impeller connected to the lower inner end of the shot blasting chamber by a bearing, a shot blasting motor fixedly connected to the rear shaft end of the impeller, a coarse shot chamber arranged at the upper inner end of the shot blasting chamber, a fine shot chamber arranged at the upper inner end of the shot blasting chamber, a first switch valve arranged at the lower side of the coarse shot chamber, a second switch valve arranged at the lower side of the fine shot chamber, a start button fixedly installed on the left side of the grinding box, a start chamber arranged inside the grinding box, a start piston movably connected to the inner side of the start chamber, and a return spring fixedly installed at the upper inner end of the start chamber, which has the characteristics of strong practicality and graded processing.

[0004] Although the aforementioned patent achieves separate storage and selective use of shot of different particle sizes by setting up independent coarse shot chambers and fine shot chambers, and cooperating with corresponding switching valves, in continuous shot blasting operations, the shot will be continuously broken and worn, and mixed with dust and debris falling off the workpiece surface. Existing equipment lacks the function of online, dynamic fine screening and purification of circulating shot, which leads to a decrease in the purity of shot under long-term use. This causes dust and ineffective debris to repeatedly impact the workpiece surface with the shot, which not only affects the shot blasting quality, but also easily causes secondary pollution of the workpiece and accelerates equipment wear. Secondly, during the process of feeding the shot into the hopper, blockages such as "bridging" or "rat holes" are very likely to occur, resulting in interruption or uneven feeding, which leads to poor shot blasting effect on the workpiece.

[0005] Therefore, this utility model provides a shot blasting machine with a graded grinding function. Utility Model Content

[0006] To address the problems of existing technologies lacking shot purification functions, which leads to decreased shot blasting quality and easy clogging during feeding, the purpose of this utility model is to provide a shot blasting machine with a graded grinding function.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a shot blasting machine with a graded grinding function, comprising a graded shot blasting machine, wherein a feeding mechanism is provided on the upper side of the graded shot blasting machine for conveying shot into the shot blasting chamber, the feeding mechanism comprising: The anti-clogging component includes a coarse material bin on one side of the upper part of the grading shot blasting machine, and a fine material bin on the other side of the upper part of the grading shot blasting machine. A disturbance wheel is rotatably installed in the middle of the coarse material bin and the fine material bin. A driven gear is fixedly installed at one end of each of the two disturbance wheels. A feeding impeller is rotatably installed at the lower part of the coarse material bin and the fine material bin. A drive component is provided at one end of each of the two feeding impellers. A drive gear is provided at the other end of each of the two feeding impellers. The two drive gears and the driven gear are meshed and connected to each other. The screening assembly is located above the coarse and fine material bins and is used to sort the pellets entering the bins.

[0008] Preferably, the screening assembly includes a fine filter plate disposed on one side of the upper part of the grading shot blasting machine, a coarse filter plate that cooperates with the fine filter plate is installed on the other side of the upper part of the grading shot blasting machine, two sets of symmetrically distributed springs are fixedly installed on the upper part of the grading shot blasting machine, the bottom ends of the fine filter plate and the coarse filter plate are fixedly installed on the top ends of the springs, and multiple staggered baffles are fixedly installed on the upper parts of the fine filter plate and the coarse filter plate.

[0009] Preferably, the drive assembly includes a drive motor fixedly installed on one side of the upper part of the grading shot blasting machine, and one end of the feeding impeller is fixedly installed on the drive end of the drive motor.

[0010] Preferably, a feeding hopper is fixedly installed on one side of the top of the grading shot blasting machine, and a negative pressure adsorption pipe is fixedly installed on one side of the upper part of the grading shot blasting machine. The other end of the negative pressure adsorption pipe is connected to the drive end of an external vacuum cleaner.

[0011] Preferably, a partition is fixedly installed on one side of the upper part of the grading shot blasting machine, which separates the dust from the shot material below.

[0012] Preferably, the upper part of the grading shot blasting machine is fixedly installed with two sets of telescopic rods, and the bottom ends of the coarse material bin and the fine material bin are fixedly installed at the top of the telescopic rods.

[0013] Beneficial effects This utility model provides a shot blasting machine with a graded grinding function. Compared with the prior art, it has the following advantages: 1. This application utilizes an anti-blocking component. When the drive motor starts and rotates the feed impeller, it achieves quantitative output of shot. Simultaneously, through the meshing of the drive gear and the driven gear, it synchronously drives the disturbance wheel in the middle of the hopper to rotate. The continuous rotation of the disturbance wheel can effectively disperse the shot and destroy any "bridging" or "rat hole" shaped material arches that may form. This avoids blockage of shot at the outlets of the coarse and fine hoppers, ensuring a continuous, stable, and smooth shot supply. It significantly reduces equipment downtime caused by material interruption or uneven supply, and improves the overall efficiency and reliability of shot blasting operations.

[0014] 2. This application utilizes a screening component. After the mixed shot enters through the hopper, it is first pre-screened on a fine filter plate to separate most of the dust and debris. Subsequently, the shot slides onto a coarse filter plate. Under the combined action of the shot impact and spring support, the coarse and fine filter plates vibrate continuously, achieving fine screening of the shot. At the same time, combined with a negative pressure adsorption pipe, the screened harmful dust can be promptly removed, effectively purifying the recycled shot and improving the surface quality of the workpiece after shot blasting.

[0021] 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.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a shot blasting machine with graded grinding function, including a graded shot blasting machine 1, whose interior is divided into three independent areas by stainless steel baffles: a shot blasting chamber, a recovery chamber, and an equipment installation cavity, ensuring that the shot blasting process and equipment operation do not interfere with each other. A feeding mechanism 2 is provided on the upper side of the graded shot blasting machine 1 for conveying shot into the shot blasting chamber. The feeding mechanism 2 includes: The anti-clogging component 21 includes a coarse material bin 211 located on one side of the upper part of the grading shot blasting machine 1, and a fine material bin 212 located on the other side of the upper part of the grading shot blasting machine 1. A disturbance wheel 217 is rotatably installed in the middle of the coarse material bin 211 and the fine material bin 212. By rotating the disturbance wheel 217, the bridging and rat hole phenomena of the shot in the bin can be avoided. A driven gear 216 is fixedly installed at one end of each of the two disturbance wheels 217. A feeding impeller 214 is rotatably installed at the lower part of the coarse material bin 211 and the fine material bin 212. The feeding impeller 214 has a six-blade structure. The blades are made of wear-resistant alloy material. The diameter of the impeller body matches the diameter of the discharge port of the bin. The shot is quantitatively output by rotating the blades. The output can be adjusted by the rotation speed. A drive component is provided at one end of each of the two feeding impellers 214. A drive gear 215 is provided at the other end of each of the two feeding impellers 214. The two drive gears 215 and the driven gear 216 are meshed and connected to each other. The screening component 22 is located above the coarse material bin 211 and the fine material bin 212, and is used to sort the pellets entering the bins.

[0023] The screening assembly 22 includes a fine filter plate 221 installed on one side of the upper part of the grading shot blasting machine 1. The shot cannot fall through the filter holes of the fine filter plate 221 and slides onto the coarse filter plate 222, which is used to separate the shot and the metal powder debris mixed with it. On the other side of the upper part of the grading shot blasting machine 1, a coarse filter plate 222 is installed to cooperate with the fine filter plate 221. The fine shot falls into the fine material bin 212 through the coarse filter holes of the coarse filter plate 222, while the coarse shot slides into the coarse material bin 211 through the coarse filter plate 222, thus achieving the separation of coarse and fine shot. Two sets of symmetrically distributed springs 225 are fixedly installed on the upper part of the grading shot blasting machine 1. The springs 225 are cylindrical helical compression springs. The bottom ends of the fine filter plate 221 and the coarse filter plate 222 are fixedly installed on the top ends of the springs 225. Multiple staggered baffles 223 are fixedly installed on the upper parts of the fine filter plate 221 and the coarse filter plate 222.

[0024] The drive assembly includes a drive motor 213 fixedly installed on one side of the upper part of the grading shot blasting machine 1. Both drive motors 213 are three-phase asynchronous motors and are connected to the feed impeller 214 through a gearbox (reduction ratio 1:75). One end of the feed impeller 214 is fixedly installed on the drive end of the drive motor 213.

[0025] A feeding hopper 218 is fixedly installed on one side of the top of the grading shot blasting machine 1. The feeding hopper 218 is connected to the shot recovery equipment of the grading shot blasting machine 1. A negative pressure adsorption pipe 219 is fixedly installed on one side of the upper part of the grading shot blasting machine 1. The other end of the negative pressure adsorption pipe 219 is connected to the drive end of an external vacuum cleaner.

[0026] A partition 224 is fixedly installed on one side of the upper part of the grading shot blasting machine 1, located between the fine filter plate 221 and the coarse filter plate 222. The partition 224 separates the dust from the lower shot. The dust is screened by the impact of the shot on the fine filter plate 221, which causes the compression spring 225 to vibrate. The dust falls to the top of the partition 224 and is then picked up by an external vacuum cleaner.

[0027] Two sets of telescopic rods 226 are fixedly installed on the upper part of the grading shot blasting machine 1. The bottom ends of the coarse material bin 211 and the fine material bin 212 are fixedly installed on the top of the telescopic rods 226. The telescopic rods 226 can prevent the coarse filter plate 222 and the fine filter plate 221 from shaking during the up-and-down vibration.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] During operation, the mixed shot is first recovered by the recycling system and then enters the device through the feed hopper 218. The shot first falls onto the fine filter plate 221. Due to the small filter holes of the fine filter plate 221, qualified shot (including coarse and fine grades) cannot pass through directly. Instead, under its own gravity and inertia, it slides down the inclined plate surface onto the coarse filter plate 222. During this process, the fine metal powder and debris mixed in the shot are initially separated. Under the continuous impact of the shot and the support of the spring 225, the fine filter plate 221 and the coarse filter plate 222 will generate continuous vibration. When the shot is screened on the coarse filter plate 222, the fine shot passes through the filter holes of the coarse filter plate 222 and finally falls into the fine material bin 212, while the coarse shot slides down the inclined surface of the coarse filter plate 222 and enters the coarse material bin 211. The shot is precisely graded and stored. Meanwhile, the sieved light dust is sucked to the upper area of ​​the partition 224 by the suction force generated by the negative pressure adsorption pipe 219 of the external vacuum cleaner and is eventually sucked away, achieving efficient separation of shot and harmful dust. When shot needs to be supplied to the shot blasting chamber, the drive motor 213 is started to drive the feed impeller 214 to rotate. The six-bladed structure of the feed impeller 214 delivers the shot in the chamber quantitatively and evenly. At the same time, the drive gear 215 at one end of the feed impeller 214 drives the driven gear 216 meshing with it to rotate, thereby driving the disturbance wheel 217 to rotate in the hopper. The rotation of the disturbance wheel 217 effectively breaks up any possible "bridging" or "rat hole" shaped material arches, completely avoiding the blockage of shot in the hopper and ensuring the continuity and stability of the supply.
