Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, and in particular to a shot blasting machine outlet cleaning device. Background Technology

[0002] Shot blasting machines can simultaneously remove sand, cores, and clean castings. Small castings are conveyed out by the track after shot blasting. A cleaning device is usually installed at the exit to clean the shot off the castings and collect the shot.

[0003] A search revealed Chinese patent CN221583281U, which discloses an outlet cleaning device for a shot blasting machine. The cleaning box is located on the upper surface of the drive housing, and a cleaning assembly is installed inside the cleaning box. A conveyor belt is installed inside the drive housing, and its surface has through holes. A collection box and a vibrating motor are located inside the conveyor belt. The cleaning assembly includes a transmission rod vertically penetrating the lifting plate and a cleaning motor mounted on the upper surface of the lifting plate. The output end of the cleaning motor is connected to the top of the transmission rod via a transmission belt. A cleaning disc is located at the bottom of the transmission rod, and cleaning brush bristles are located at the bottom of the cleaning disc. This patent uses a conveyor belt to move castings. During the movement, the vibrating motor vibrates, causing the castings on the conveyor belt to continuously tumble, causing the shot to fall off. Simultaneously, the rotating cleaning assembly cleans the tumbling castings, removing shot from all directions.

[0004] In the aforementioned existing technical solution, the cleaning motor drives the cleaning disc to rotate, causing the cleaning brush bristles to clean the surface of the casting. At the same time, the vibration motor causes the casting to vibrate, facilitating the falling off of steel balls from the surface of the casting. However, in actual use, due to the vibration of the vibration motor, the casting will momentarily become airborne and not in contact with the conveyor belt, while the cleaning brush bristles remain in contact with the casting. The rotation of the cleaning brush bristles will cause the position of the casting to shift, resulting in the cleaning brush bristles being unable to clean the casting effectively. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model proposes a shot blasting machine outlet cleaning device. By rotating the cleaning motor, the sliding bar moves repeatedly on the top of the screening conveyor belt to clean the steel balls on the castings at the top of the screening conveyor belt. The castings are always in contact with the screening conveyor belt to ensure the stability of the castings' position.

[0006] The technical solution to achieve the purpose of this utility model is as follows: a shot blasting machine outlet cleaning device, including a mounting box, two drive shafts are rotatably mounted on the inner side wall of the mounting box, a screening conveyor belt is sleeved on the side wall of the two drive shafts, a drive motor is fixedly mounted on the side wall of the mounting box, the output end of the drive motor is fixedly connected to the adjacent drive shaft, a sliding groove is opened on the side wall of the mounting box, an installation strip is slidably mounted inside the sliding groove, multiple sliding strips are fixedly mounted at equal intervals on the installation strip near the inner side wall of the mounting box, a brush is fixedly mounted on the bottom wall of the sliding strip, a support frame is fixedly mounted on the side wall of the installation strip away from the sliding strip, a return spring is fixedly mounted on the side wall of the support frame, the end of the return spring near the mounting box is fixedly connected to the side wall of the mounting box, an installation rod is fixedly mounted on the side wall of the installation strip away from the sliding strip, two meshing push tooth plates are fixedly mounted on the end of the installation rod away from the sliding strip, and a cleaning motor is fixedly mounted on the side wall of the push tooth plates away from the sliding strip.

[0007] In some embodiments, two positioning slots are provided on the inner side wall of the mounting box at the end away from the drive motor, and the two ends of the drive shaft away from the drive motor are rotatably mounted inside the adjacent positioning slots.

[0008] In some embodiments, two support telescopic rods are fixedly installed on the inner sidewall of the mounting box, with the tops of the two support telescopic rods aligned with the top of the inner sidewall of the screening conveyor belt.

[0009] In some embodiments, a plurality of limiting grooves are provided on the side wall of the mounting box away from the sliding groove, and the ends of the plurality of sliding strips away from the mounting strip are respectively slidably installed inside the limiting grooves.

[0010] In some embodiments, a collection box is slidably installed on the bottom of the inner side wall of the mounting box, multiple through holes are opened on the side wall of the screening conveyor belt, and a fixing frame is fixedly installed on the side wall of the cleaning motor.

[0011] In some embodiments, a protective box is fixedly installed on the side wall of the mounting box, and the drive motor, support frame and cleaning motor are all located inside the protective box.

[0012] Compared with the prior art, the significant advantages of this utility model are:

[0013] Firstly, this invention uses a drive motor to rotate a nearby drive shaft, which in turn drives the screening conveyor belt. The casting to be cleaned is placed on top of the screening conveyor belt, and the casting moves with the belt. The cleaning motor is fixed in place by a mounting bracket. The cleaning motor's output drives a nearby push plate to rotate, and the two push plates mesh with each other. The push plate furthest from the cleaning motor is fixed to the side wall of the mounting rod. Therefore, the push plate closer to the mounting rod moves towards the inside of the mounting box as the cleaning motor's output rotates. The sliding bar moves the brush away from the cleaning motor. When the two push plates come into contact, the elasticity of the return spring causes the mounting bar to return to its original position along with the support frame. The rotation of the cleaning motor causes the sliding bar to move repeatedly on top of the screening conveyor belt, cleaning the steel balls on the casting at the top of the belt. This solves the problem of unstable casting position in existing cleaning devices.

[0014] Secondly, this utility model extends the output end of the support telescopic rod upward to lift the top of the screening conveyor belt, reducing the distance between the screening conveyor belt and the brush, which facilitates the cleaning of castings of different sizes. When the output end of the support telescopic rod is lifted upward, the drive shaft away from the drive motor can slide inside the positioning groove, adjusting the distance between the two drive shafts so that the screening conveyor belt can bulge upward fully, ensuring the stability of the screening conveyor belt position.

Detailed Implementation

[0022] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0023] This utility model provides an improved shot blasting machine outlet cleaning device. The technical solution of this utility model is as follows:

[0024] like Figures 1-4As shown, a shot blasting machine outlet cleaning device includes a mounting box 1. A collection box 2 is slidably mounted on the bottom of the inner side wall of the mounting box 1. Two drive shafts 3 are rotatably mounted on the inner side wall of the mounting box 1. A screening conveyor belt 4 is sleeved on the side wall of the two drive shafts 3. Multiple through holes are opened on the side wall of the screening conveyor belt 4. A drive motor 5 is fixedly mounted on the side wall of the mounting box 1. The output end of the drive motor 5 is fixedly connected to the adjacent drive shaft 3. A sliding groove 8 is opened on the side wall of the mounting box 1. An installation strip 9 is slidably mounted inside the sliding groove 8. Multiple sliding strips are fixedly mounted at equal intervals on one end of the installation strip 9 near the inner side wall of the mounting box 1. A brush 11 is fixedly installed on the bottom wall of the mounting strip 10. A support frame 13 is fixedly installed on the side wall of the mounting strip 9 away from the sliding strip 10. A return spring 14 is fixedly installed on the side wall of the support frame 13. One end of the return spring 14 near the mounting box 1 is fixedly connected to the side wall of the mounting box 1. A mounting rod 15 is fixedly installed on the side wall of the mounting strip 9 away from the sliding strip 10. Two meshing push tooth plates 16 are fixedly installed on the end of the mounting rod 15 away from the sliding strip 10. A cleaning motor 17 is fixedly installed on the side wall of the push tooth plates 16 away from the sliding strip 10. A fixing bracket 18 is fixedly installed on the side wall of machine 17; the output end of the transmission motor 5 drives the adjacent transmission shaft 3 to rotate, causing the screening conveyor belt 4 to move. Then, the casting to be cleaned is placed on top of the screening conveyor belt 4. The casting moves with the transmission of the screening conveyor belt 4. The fixing bracket 18 fixes the position of the cleaning motor 17. The output end of the cleaning motor 17 drives the adjacent push tooth plate 16 to rotate. The two push tooth plates 16 mesh with each other. The push tooth plate 16 away from the cleaning motor 17 is fixed on the side wall of the mounting rod 15. Therefore, the push tooth plate 16 close to the mounting rod 15... As the output of the cleaning motor 17 rotates, the sliding bar 10 moves into the mounting box 1. The sliding bar 10 drives the brush 11 to move away from the cleaning motor 17. When the two push tooth plates 16 are in contact with each other, the elasticity of the return spring 14 causes the mounting bar 9 to return to its original position along with the support frame 13. As the cleaning motor 17 rotates, the sliding bar 10 moves repeatedly on the top of the screening conveyor belt 4 to clean the steel balls on the casting at the top of the screening conveyor belt 4. The cleaned steel balls move downward through the through holes on the screening conveyor belt 4 and fall into the collection box 2, where they are collected.

[0025] like Figures 1-4As shown, in one embodiment, to ensure the stability of the sliding bar 10 position, a plurality of limiting grooves 12 are provided on the side wall of the mounting box 1 away from the sliding groove 8. The ends of the plurality of sliding bars 10 away from the mounting bar 9 are respectively slidably installed inside the limiting grooves 12. The limiting grooves 12 restrict the position of the sliding bars 10, so that the sliding bars 10 can slide stably inside the mounting box 1. Two supporting telescopic rods 7 are fixedly installed on the inner side wall of the mounting box 1, and the top ends of the two supporting telescopic rods 7 are aligned with the top end of the inner side wall of the screening conveyor belt 4. The output ends of the supporting telescopic rods 7 extend upwards. The top of the screening conveyor belt 4 is lifted, reducing the distance between the screening conveyor belt 4 and the brush 11, making it easier to clean castings of different sizes. Two positioning grooves 6 are opened on the inner side wall of the mounting box 1 at the end away from the drive motor 5. The two ends of the drive shaft 3 away from the drive motor 5 are rotatably installed inside the adjacent positioning grooves 6. When the output end of the support telescopic rod 7 is lifted upward, the drive shaft 3 away from the drive motor 5 can slide inside the positioning groove 6, adjusting the distance between the two drive shafts 3 so that the screening conveyor belt 4 can fully protrude upward, ensuring the stability of the position of the screening conveyor belt 4.

[0026] like Figures 1-4 As shown, in one embodiment, a protective box 19 is fixedly installed on the side wall of the mounting box 1, and the drive motor 5, support frame 13 and cleaning motor 17 are all located inside the protective box 19; by enclosing the drive motor 5, support frame 13 and cleaning motor 17 inside the protective box 19, the drive motor 5 and cleaning motor 17 are protected, thereby improving the safety of the device.

[0027] The specific working method is as follows: the output end of the drive motor 5 drives the adjacent drive shaft 3 to rotate, causing the screening conveyor belt 4 to move. Then, the casting to be cleaned is placed on top of the screening conveyor belt 4. The casting moves with the transmission of the screening conveyor belt 4. The position of the cleaning motor 17 is fixed by the fixing bracket 18. The output end of the cleaning motor 17 drives the adjacent push tooth plate 16 to rotate. The two push tooth plates 16 mesh with each other. The push tooth plate 16 away from the cleaning motor 17 is fixed on the side wall of the mounting rod 15. Therefore, the push tooth plate 16 near the mounting rod 15 will move with the cleaning motor 17. The rotation of the output end of the cleaning motor 17 moves it towards the interior of the mounting box 1. The sliding bar 10 drives the brush 11 to move away from the cleaning motor 17. When the two push tooth plates 16 are in contact with each other, the elasticity of the return spring 14 causes the mounting bar 9 to return to its original position along with the support frame 13. The rotation of the cleaning motor 17 causes the sliding bar 10 to move repeatedly on the top of the screening conveyor belt 4 to clean the steel balls on the casting at the top of the screening conveyor belt 4. The cleaned steel balls move downward through the through holes on the screening conveyor belt 4 and fall into the interior of the collection box 2, where the steel balls are collected.
