Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine cleaning technology, specifically to a cleaning device for shot blasting machines. Background Technology

[0002] A shot blasting machine is a casting equipment that uses high-speed shot blasting to clean or strengthen the surface of castings. Shot blasting machines can simultaneously remove sand, cores, and clean castings. In some regions, they are also colloquially called sandblasting machines or blasting machines. Shot blasting is a treatment technology that uses a shot blaster to propel steel shot at high speed onto the surface of a material. Compared to other surface treatment technologies, it is faster and more effective, and can be used to reduce fatigue life of parts, increase surface stress, increase component strength, or prevent fretting after the casting process has been partially completed or stamped.

[0003] Existing shot blasting machines often mix shot with impurities after it is thrown out. During subsequent cleaning, the shot needs to be sorted separately for recycling, which is inconvenient, time-consuming, and labor-intensive. Some devices are equipped with sorting screens to distinguish between the shot and impurities in a timely manner. However, if there are too many shot and impurities, the screen will become clogged, slowing down the shot sorting efficiency and hindering production. Utility Model Content

[0004] In view of the above-mentioned problems in the existing technology, the technical problem to be solved by this utility model is that: after the shot is thrown out, the shot of the existing shot blasting machine will be mixed with impurities. During the later cleaning, the shot needs to be sorted separately for recycling, which is inconvenient, time-consuming and labor-intensive. Some devices are equipped with sorting screens to facilitate the timely differentiation of the shot and impurities after cleaning. However, if there are too many shot and impurities, the screen will be blocked, the shot sorting efficiency will be slowed down, which is not conducive to production.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a cleaning device for a shot blasting machine, comprising: Collection box; A screen is installed inside the collection box to divide the collection box into an upper projectile chamber and a lower impurity chamber; A cleaning mechanism, installed within the impurity chamber, includes a nozzle and an air inlet pipe; one end of the air inlet pipe is connected to the nozzle to introduce high-pressure gas into the nozzle; the outlet of the nozzle faces the screen to backflush the screen and cause the projectiles within the projectile chamber to rub against each other; and The drive mechanism, through the gas in the intake pipe, drives the cleaning mechanism to reciprocate within the impurity chamber.

[0006] Preferably, the drive mechanism includes: a mounting base, a reciprocating screw, a nut seat, and a transmission assembly; the mounting base is slidably mounted in the collection box in the horizontal direction; the nozzle is mounted on the mounting base; the reciprocating screw is fixedly mounted in the collection box and is arranged along the sliding direction of the mounting base; the nut seat is rotatably mounted on the mounting base and is threadedly connected to the reciprocating screw; the transmission assembly drives the nut seat to rotate through the gas in the air inlet pipe.

[0007] Preferably, the transmission assembly includes: a rotating shaft, fan blades, a first gear, and a second gear; the rotating shaft is rotatably mounted on a mounting base, and one end of the fan blades extends into the air intake pipe; a plurality of fan blades are disposed in the air intake pipe, and the plurality of fan blades are mounted on the rotating shaft in a circular array with the axis of the rotating shaft as the center; the first gear is coaxially mounted on the other end of the rotating shaft; the second gear is coaxially fixed to the nut seat, and the second gear meshes with the first gear.

[0008] Preferably, the mounting base is slidably mounted inside the collection box via a guide rod; the guide rod is mounted horizontally inside the collection box and slides through the mounting base.

[0009] Preferably, multiple nozzles are provided, and all multiple nozzles are connected to the air inlet pipe, and the multiple nozzles are arranged in a direction perpendicular to the reciprocating movement of the cleaning mechanism.

[0010] Compared with the prior art, the present invention has at least the following advantages: In this invention, after shot blasting, the mixture of shot and impurities enters the shot chamber. The shot passes through the filter screen and falls above the impurity chamber, while the impurities are intercepted on the screen surface. High-pressure gas is introduced into the air inlet pipe of the cleaning mechanism and then sprayed out through the nozzle. The sprayed high-pressure gas blows towards the screen to remove impurities adhering to the screen surface to avoid clogging. On the other hand, it blows the shot to flow and tumble in the impurity chamber, causing the shot to rub and collide with each other, thereby peeling off the fine impurities adhering to the shot surface and further purifying the shot. At the same time, the drive mechanism uses the gas power in the air inlet pipe to drive the cleaning mechanism to move back and forth in the impurity chamber, so that the blowing range of the nozzle covers more areas of the screen and the shot accumulation below, ensuring that the screen is cleaned without dead corners and that the shot is sufficiently rubbed. This design utilizes the multiple effects of high-pressure gas to ensure unobstructed screen flow, thereby improving separation efficiency. It also enables deep purification through shot self-friction, enhancing shot recovery rate and cleanliness. Furthermore, the gas-powered cleaning mechanism eliminates the need for an additional power source, saving energy, reducing equipment downtime for maintenance, and ultimately improving the overall operating efficiency and material recycling rate of the shot blasting machine.

[0016] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0017] See Figures 1-3 The present invention provides an embodiment of a cleaning device for a shot blasting machine, comprising: a collection box 1, a screen 2, a cleaning mechanism 3, and a driving mechanism 4; the screen 2 is installed in the collection box 1 to divide the collection box 1 into an upper shot chamber 11 and a lower impurity chamber 12; the cleaning mechanism 3 is installed in the impurity chamber 12, and the cleaning mechanism 3 includes: a nozzle 31 and an air inlet pipe 32; one end of the air inlet pipe 32 is connected to the nozzle 31 to introduce high-pressure gas into the nozzle 31; the air outlet of the nozzle 31 faces the screen 2 to backflush the screen 2 and drive the shot in the shot chamber 11 to rub against each other; the driving mechanism 4 drives the cleaning mechanism 3 to reciprocate within the impurity chamber 12 through the gas in the air inlet pipe 32.

[0018] In practice, after shot blasting, the mixture of shot and impurities enters the shot chamber 11. The shot passes through the filter screen and falls into the impurity chamber 12, while the impurities are intercepted on the surface of the screen 2. After high-pressure gas is introduced into the air inlet pipe 32 of the cleaning mechanism 3, the gas is sprayed out through the nozzle 31. The sprayed high-pressure gas blows towards the screen 2 to remove the impurities attached to the surface of the screen 2 to avoid clogging. On the other hand, it blows the shot to flow and roll in the impurity chamber 12, causing the shot to rub and collide with each other, thereby peeling off the fine impurities attached to the surface of the shot and further purifying the shot. At the same time, the drive mechanism 4 uses the gas power in the air inlet pipe 32 to drive the cleaning mechanism 3 to move back and forth in the impurity chamber 12, so that the blowing range of the nozzle 31 covers more areas of the screen 2 and the shot accumulation below, ensuring that the screen 2 is cleaned without dead corners and that the shot is sufficiently rubbed. This design, through the multiple effects of high-pressure gas, can ensure the smooth flow of screen 2 to improve separation efficiency, and can also achieve deep purification through the self-friction of the shot, thereby improving the shot recovery rate and cleanliness. Furthermore, the gas-powered cleaning mechanism 3 does not require an additional power source, saving energy consumption, reducing equipment downtime for maintenance, and improving the overall operating efficiency and material recycling rate of the shot blasting machine.

[0019] See Figures 1-3 In other embodiments, the drive mechanism 4 includes: a mounting base 41, a reciprocating screw 42, a nut seat 43, and a transmission assembly; the mounting base 41 is slidably mounted in the collection box 1 in the horizontal direction; further, the mounting base 41 is slidably mounted in the collection box 1 via a guide rod 48; the guide rod 48 is mounted in the collection box 1 in the horizontal direction and slides through the mounting base 41; the guide rod 48 is provided so that the mounting base 41 can slide stably; the nozzle 31 is mounted on the mounting base 41; the reciprocating screw 42 is fixedly mounted in the collection box 1 and is arranged along the sliding direction of the mounting base 41; the nut seat 43 is rotatably mounted on the mounting base 41 and is threadedly connected to the reciprocating screw 42; the transmission assembly drives the nut seat 43 to rotate through the gas in the air inlet pipe 32.

[0020] In practice, when high-pressure gas is introduced into the air inlet pipe 32, the gas is sprayed out through the nozzle 31 to blow away the screen 2 and the shot. The gas also drives the nut seat 43 to rotate around its own axis through the transmission component. Since the nut seat 43 is threadedly connected to the fixed reciprocating screw 42, its rotation is converted into horizontal movement along the screw axis, which in turn drives the mounting base 41 and the entire cleaning mechanism 3 to slide back and forth in the impurity chamber 12. This driving method cleverly utilizes the power of high-pressure gas, which not only realizes the reciprocating motion of the cleaning mechanism 3 to expand the blowing range, but also eliminates the need for additional power sources such as motors. It shares a system with the cleaning air source, simplifying the equipment structure.

[0021] See Figures 1-3In other embodiments, the transmission assembly includes: a rotating shaft 44, fan blades 45, a first gear 46, and a second gear 47; the rotating shaft 44 is rotatably mounted on the mounting base 41, and one end of the fan blades 45 extends into the air intake pipe 32; a plurality of fan blades 45 are disposed in the air intake pipe 32, and the plurality of fan blades 45 are mounted on the rotating shaft 44 in a circular array with the axis of the rotating shaft 44 as the center; the other end of the rotating shaft 44 is coaxially mounted with the first gear 46; the second gear 47 is coaxially fixed with the nut seat 43, and the second gear 47 meshes with the first gear 46.

[0022] When high-pressure gas is introduced into the intake pipe 32, the airflow impacts multiple fan blades 45 located within the intake pipe 32. These fan blades 45 are arranged in a circular array around the axis of the rotating shaft 44, causing the shaft 44 to rotate on the mounting base 41. The first gear 46 at the other end of the shaft 44 rotates synchronously with the shaft, and the second gear 47, meshing with the first gear 46, rotates accordingly, thereby rotating the nut seat 43. Since the nut seat 43 is threadedly engaged with the fixed reciprocating screw 42, its rotation is converted into horizontal movement along the screw, causing the mounting base 41 and the cleaning mechanism 3 to slide back and forth within the impurity chamber 12. At this time, the high-pressure gas ejected from the nozzle 31 both sweeps away impurities on the surface of the screen 2 and causes the projectiles to rub against each other. The reciprocating nozzle 31 can cover a wider area, improving the cleaning and purification effect. This transmission component is driven directly by the airflow in the intake pipe 32 without the need for additional power. It converts the kinetic energy of the airflow into mechanical motion through the cooperation of the fan blades 45 and gears. The structure is compact and the transmission is stable, ensuring the efficient operation of the cleaning mechanism 3 and further improving the material handling efficiency of the shot blasting machine.

[0023] See Figures 1-3 In another embodiment, multiple nozzles 31 are provided, and all multiple nozzles 31 are connected to the air inlet pipe 32. The multiple nozzles 31 are arranged in a direction perpendicular to the reciprocating movement of the cleaning mechanism 3. This multi-nozzle design, combined with reciprocating movement, not only expands the single purging range, but also ensures that there are no dead corners in the cleaning on the same movement trajectory through the lateral distribution of the nozzles 31, thereby enhancing the impurity removal effect and the efficiency of shot friction purification.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
