Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, and in particular to an anti-clogging vertical shot blasting machine. Background Technology

[0002] A vertical shot blasting machine is a machine that performs shot blasting treatment vertically. It uses the high-speed rotation of the shot blaster to accelerate abrasive materials such as steel shot to a very high speed and throw them at the surface of the workpiece to be cleaned, thereby achieving cleaning and strengthening effects. A vertical shot blasting machine is mainly composed of a separation chamber, a storage hopper, an elevator, an impeller, and other parts.

[0003] Generally speaking, the steel shot used in vertical shot blasting machines needs to be reused. However, the steel shot will be mixed with impurities such as metal dust. Once this dust clogs the steel shot feeding mechanism, it will affect the normal operation of the shot blasting machine.

[0004] A publicly available technical solution, CN220296862U, discloses a vertical shot blasting machine, including a shot blasting machine body, an impurity collection component, and an impurity suction component. The inner wall of the shot blasting machine body is equipped with a shot removal component, and a door is hinged to the surface of the shot blasting machine body. The shot can be filtered through a filter screen, achieving the goal of conveniently handling dust generated during the shot blasting process. This prevents dust and impurities from falling into the feed trough, avoiding blockage of the shot during transport. Simultaneously, the filter screen can be easily cleaned, ensuring the normal operation of the impurity suction component.

[0005] In actual implementation of the above technical solution, the feeding trough is located below the filter screen, and the steel shot descends at a relatively fast speed. For the feeding trough, which is always open, dust and impurities will inevitably enter the feeding trough. Summary of the Invention

[0006] The purpose of this invention is to provide an anti-clogging vertical shot blasting machine that can close the steel shot recovery tank as needed and open it again when necessary, thereby preventing a large amount of dust and impurities from entering the steel shot recovery tank and solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a vertical shot blasting machine for preventing blockage, comprising a shot blasting machine housing, an elevator for lifting steel shot is provided at the top of the shot blasting machine housing, and a steel shot recovery assembly for collecting steel shot is provided inside the shot blasting machine housing, a dust collection assembly for cleaning dust is provided on one side of the steel shot recovery assembly, and a door is connected to the front end of the shot blasting machine housing via a hinge;

[0026] 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.

[0027] This utility model provides a technical solution:

[0028] Please see Figures 1 to 4A vertical shot blasting machine for preventing blockage includes a shot blasting machine housing 1, an elevator 2 for lifting steel shot is provided on the top of the shot blasting machine housing 1, a steel shot recycling component 4 for collecting steel shot is provided inside the shot blasting machine housing 1, a dust collection component 3 for cleaning dust is provided on one side of the steel shot recycling component 4, and a door 5 is connected to the front end of the shot blasting machine housing 1 by a hinge.

[0029] The shot recovery assembly 4 includes a recovery trough 401 installed inside the lower part of the shot blasting machine housing 1. The recovery trough 401 is connected to the shot blasting machine housing 1 and has a feed inlet. Two sets of baffles 402 are slidably installed inside the feed inlet, and electromagnets 403 are fixedly installed on both sets of baffles 402.

[0030] By adopting the above technical solution, when it is necessary to close the recycling tank 401 to prevent steel shot from entering the recycling tank 401, the two sets of baffles 402 can be slidably closed by energizing the electromagnet 403. After the baffles 402 slide and stick together, they can block the recycling tank 401. At this time, steel shot cannot enter the interior of the recycling tank 401, thereby preventing steel shot mixed with metal dust from entering the recycling tank 401.

[0031] Specifically, such as Figure 5 As shown, two sets of baffles 402 are magnetically attracted by electromagnets 403, and the baffles 402 penetrate the inner wall of the recovery tank 401. The other end of the baffles 402 is fixedly connected to a connecting spring 404, and the end of the connecting spring 404 is fixed to the shot blasting machine housing 1. A rotating shaft 405 is installed inside the recovery tank 401, and a spiral blade 406 is installed on the surface of the rotating shaft 405 by bolts. One end of the rotating shaft 405 is fixedly connected to the power output end of a servo motor. The end of the recovery tank 401 is provided with a discharge port, and the discharge port of the recovery tank 401 is connected to the feed port of the elevator 2.

[0032] By adopting the above technical solution, when steel shot needs to be recycled, the electromagnet 403 is de-energized. Since the electromagnet 403 is energized, the connecting spring 404 is in a stretched state when the two sets of baffles 402 are in contact. When the electromagnet 403 is de-energized, the baffles 402 can be pulled to slide under the elastic action of the connecting spring 404. There is a certain gap between the baffles 402, and the steel shot can enter the recycling tank 401 through this gap. After the servo motor is started, the power output end of the servo motor drives the rotating shaft 405 to rotate. The steel shot moves backward with the rotation of the spiral blade 406 until it reaches the discharge port of the recycling tank 401. It enters the feed port of the elevator 2 through the discharge port of the recycling tank 401 and is lifted upward by the elevator 2 to the top of the shot blasting machine housing 1. Through the acceleration mechanism set in the shot blasting machine housing 1, the steel shot is accelerated and re-entered into the shot blasting machine housing 1 to polish the surface of the metal workpiece placed in the shot blasting machine housing 1.

[0033] Specifically, such as Figures 2 to 4 As shown, the dust collection assembly 3 includes a transfer box 304 embedded inside the shot blasting machine housing 1, and a filter screen 301 is slidably installed inside the transfer box 304. A guide groove 308 is provided at the connection between the filter screen 301 and the transfer box 304, and a guide slider 306 is provided inside the guide groove 308. Support springs 307 are fixedly installed at the four bottom corners of the filter screen 301, and the ends of the support springs 307 are fixed inside the transfer box 304. A dust suction pipe 305 is connected to the bottom of the transfer box 304, and a dust collection box 303 is connected to the end of the dust suction pipe 305. A suction fan 302 is installed on the top of the dust collection box 303, and the dust collection box 303 is fixed to the rear end of the shot blasting machine housing 1.

[0034] By adopting the above technical solution, after the metal workpiece is blasted by steel shot, some dust will fall off. At this time, the suction fan 302 is started. The suction fan 302 can draw in air through the dust collection box 303 and the suction pipe 305. Outside air enters the dust collection box 303 through the suction pipe 305. At this time, the steel shot and metal dust in the shot blasting machine housing 1 are drawn into the transfer box 304. When the steel shot reaches the filter screen 301, the weight of the steel shot and the suction force of the suction fan 302 act on the filter screen 301 simultaneously. The weight of the steel shot and the suction force of the suction fan 302 are greater than the supporting spring. The elastic force of spring 307 can compress the support spring 307, causing the filter screen 301 to move downward. After the suction fan 302 is turned off, the weight of the steel shot is less than the elastic force of the support spring 307, and the support spring 307 can push the filter screen 301 upward. When the rear guide groove 308 is set, the top is higher than the front guide groove 308. Thus, when the filter screen 301 moves to its highest position, the filter screen 301 is in a state of being lower in the front and higher in the back. The front end of the filter screen 301 is at the same height as the bottom of the shot blasting machine housing 1, and the steel shot can roll forward to the position of the recovery trough 401.

[0035] Working Principle: Metal workpieces are suspended inside the shot blasting machine housing 1. The elevator 2, via an acceleration mechanism, feeds the workpieces into the housing 1 for surface polishing. Simultaneously, the suction fan 302 starts, drawing external air through the suction pipe 305 into the dust collection box 303. Steel shot and metal dust inside the housing 1 are filtered by the filter screen 301 and then sucked into the transfer box 304. The steel shot remains above the filter screen 301. The weight of the steel shot and the suction force of the suction fan 302 act simultaneously on the filter screen 301. Since the combined force of the steel shot and the suction force of the suction fan 302 exceeds the elastic force of the support spring 307, the support spring 307 is compressed, causing the filter screen 301 to move downwards. After the suction fan 302 is turned off, the weight of the steel shot is less than the elastic force of the support spring 307. The spring 307 exerts its elastic force, pushing the filter screen 301 upward. The filter screen 301 is in a state of being lower in the front and higher in the back, allowing the steel shot to roll forward. When the steel shot rolls to the position of the recovery tank 401, the electromagnet 403 is de-energized. Under the elastic action of the connecting spring 404, the baffle plate 402 can be pulled to slide. There is a certain gap between the baffle plates 402, through which the steel shot can enter the recovery tank 401. The power output end of the servo motor drives the rotating shaft 405 to rotate. The steel shot moves backward with the rotation of the spiral blade 406 until it reaches the discharge port of the recovery tank 401. It then enters the feed port of the elevator 2 through the discharge port of the recovery tank 401. The elevator 2 lifts the shot shot upward to the top of the shot blasting machine housing 1 and is then re-injected into the shot blasting machine housing 1 through the acceleration mechanism.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
