Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, specifically to a through-type shot blasting cleaning machine loading and unloading device. Background Technology

[0002] Shot blasting is an important process in the manufacturing of drill rods. It removes rust and scale from the surface of the drill rod, providing a good foundation for subsequent painting. Drill rods that have undergone shot blasting and painting have better corrosion resistance, which improves both product quality and appearance.

[0003] The V-type roller conveyor shot blasting machine (hereinafter referred to as "shot blasting machine") uses a row of V-shaped rollers to transport drill rods forward in a straight line while rotating. The drill rods are fed into the shot blasting machine in an assembly line manner for shot blasting. Due to the large height difference between the center points of the rollers and the considerable weight of the drill rods, manual handling is impossible. Therefore, during the shot blasting process, a crane is used to lift and unload the drill rods. However, due to space limitations, only one crane can be used near the shot blasting machine. This crane must handle both loading and unloading, and the loading and unloading points are far apart. Because of the limited crane speed, the shot blasting machine's efficiency is extremely low, and prolonged use of the crane for lifting poses certain dangers. Utility Model Content

The third support plates are distributed inside the conveying device and are all installed on the top of the lifting device to drive the third support plates to rise above the conveying device or fall below the top of the conveying device. When the third support plate rises, it lifts the rod. Multiple first support beams inclined towards the conveying device are provided on the top of the first frame to place the rod to be shot blasted. The rod rolls along the first support beams towards the conveying device. A limiting device corresponding to the rod is provided below the first frame. The rod after being shot blasted by the shot blasting machine moves along the conveying device to the second frame.

The ends of the second support seat away from the conveying device are all connected to a second connecting rod. The second connecting rod is located below the first support beam, and at least one second telescopic device is vertically installed on the second connecting rod.

[0028] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] Reference Figures 1 to 11 This utility model provides a technical solution: a through-type shot blasting machine loading and unloading device, including a conveying device passing through the inside of the shot blasting machine 6. The two ends of the conveying device are respectively provided with a first frame 4 and a second frame 8. The top of the first frame 4 is used to place the rod to be shot blasted. The rod on the first frame 4 is conveyed into the shot blasting machine 6 by the conveying device and then sent to the second frame 8 after shot blasting. The top of the second frame 8 is used to stack the processed rod (the rod is a chisel). like Figure 1 and Figure 2 As shown, the conveying device includes a strip frame 1, with several spaced support shafts 11 rotatably mounted on the top of the strip frame 1. One end of each support shaft 11, near the first frame 4 and the second frame 8, extends outside the strip frame 1. A grooved wheel 5 is mounted on the end of each support shaft 11, and all the grooved wheels 5 are connected in a straight line. The middle of each grooved wheel 5 has a V-shaped structure, the size of which matches the diameter of the rod to be conveyed. In actual use, all support shafts 11 need to rotate synchronously, so that all Geneva wheels 5 rotate synchronously. Thus, the end of the support shaft 11 furthest from the Geneva wheel 5 is driven to rotate by the drive device. For example... Figure 3 As shown, the drive device includes a drive motor 2 installed in the strip frame 1. Both the rotating shaft of the drive motor 2 and the support shaft 11 are equipped with sprockets, which are connected by a chain. In practice, a reducer can be installed on the output end of the drive motor 2, so that the drive motor 2 is connected to each support shaft 11 through the reducer. Therefore, when the drive motor rotates, it can drive each support shaft 11 to rotate synchronously. like Figure 1 As shown, in the conveying device, only the end of the support shaft 11 closest to the grooved wheel 5 is placed inside the shot blasting machine. This is also why the support shaft 11 extends outside the strip frame 1. When the rod is placed inside the grooved wheel 5 at the top end of the strip frame 1, the rod passes through the inside of the shot blasting machine as the grooved wheel 5 rotates. It should be noted that there is a certain angle between the support shaft 11 and the rod. The advantage of this design is that it prevents the surface rotation direction of the grooved wheel 5 from being on the same straight line as the rod axis. When the surface of the grooved wheel 5 rotates, it will form an inclined tangential force at the contact point with the surface of the rod, allowing the rod to rotate continuously while moving forward with the grooved wheel 5, so that it can automatically flip over when passing through the inside of the shot blasting machine.

[0030] Furthermore, such as Figure 2 As shown, multiple third support plates 26 are provided between the first frame 4 and the conveying device, and between the second frame 8 and the conveying device. The third support plates 26 are distributed inside the conveying device, that is, the third support plates 26 are distributed between the grooved wheels 5. Because there are gaps between the grooved wheels 5, the third support plates 26 can be placed between the grooved wheels 5 without affecting the normal rotation of the grooved wheels 5. The third support plate 26 is installed on the top of the lifting device, such as Figure 8 and Figure 9 As shown, the lifting device includes a third frame 3, a third support plate 26 located at the top of the third frame 3, and a second support plate 24 vertically mounted at the bottom of the third support plate 26. The second support plate 24 is slidably connected to the third support plate 26 via guide rails, thus enabling the third support plate 26 to move up and down. Figure 8 As shown, the second support plates 24 are all mounted on the third connecting rods 7, which connect the second support plates 24 into a whole. At least one third telescopic device 27 is vertically mounted on the third connecting rods 7, and the third telescopic device 27 is vertically downward and installed inside the third frame 3. The lifting device is used to lift the third support plates 26 above the conveying device or lower them below the top of the conveying device. When the third support plates 26 are raised, the rod is lifted. Specifically, when the third telescopic device 27 extends or retracts, the third telescopic device 27 can drive all the third support plates 26 to rise or fall through the third connecting rods 7. It should be noted that the function of the third support plate 26 is as follows: First, before the rod to be shot blasted is placed on the grooved wheel 5 at the top of the first frame 4, the third support plate 26 in front of the first frame 4 is in a raised state. That is, the third support plate 26 is raised above the grooved wheel 5 under the drive of the third telescopic device 27. The rod coming from the first frame 4 falls on the third support plate 26 to avoid direct impact with the grooved wheel 5. This process is to allow the third support plate 26 to slowly descend under the drive of the third telescopic device 27, so that the rod gently falls on the top of the grooved wheel 5. Secondly, as the grooved wheel 5 rotates, the rod is fed into the shot blasting machine 6 for shot blasting. Finally, when the rod moves to the second frame 8, the third support plate 26 located in front of the second frame 8 is raised by the third telescopic device 27, thereby lifting the rod after shot blasting and then letting the rod roll along the third support plate 26 to the top of the second frame 8. In summary, the third support plate 26 located in front of the second frame 8 is used for unloading, while the third support plate 26 located at the first frame 4 is used for loading.

[0031] Furthermore, such as Figure 1 and Figure 2 As shown, multiple first support beams 14 inclined towards the conveying device are provided on the top of the first frame 4. The first support beams 14 are used to place the rod to be shot blasted. Since the first support beams 14 are inclined towards the conveying device, the rod will roll along the first support beams 14 towards the conveying device. The end of the first support beams 14 away from the conveying device is provided with a first stop 9. The first stop 9 is used to prevent the rod from falling off the end of the first support beams 14. To prevent the rod from directly impacting the grooved wheel 5, a limiting device corresponding to the rod is provided below the first frame 4, such as... Figure 6 and Figure 7 As shown, the limiting device includes a second support seat 21 disposed on the bottom side of the first support beam 14. The second support seat 21 is parallel to the first support beam 14, and the first support beam 14 and the second support seat 21 are slidably connected by a guide rail, allowing the second support seat 21 to reciprocate along the first support beam 14. The top surface of the second support seat 21 is lower than the top surface of the first support beam 14, but the top end of the second support seat 21 near the conveying device is provided with a first stop block 20 extending above the top of the first support beam 14. The first stop block 20 is used to block the rod. like Figure 6As shown, the end of the second support seat 21 away from the conveying device is connected to the second connecting rod 23. The second connecting rod 23 is located below the first support beam 14. At least one second telescopic device 22 is vertically installed on the second connecting rod 23. The second telescopic device 22 is installed below the first support beam 14. The second telescopic device 22 drives the second support seat 21 to slide back and forth along the first support beam 14. Since the rod body is blocked by the first stop 20, when the second support seat 21 moves downward along the first support beam 14, the rod body also moves downward with the first stop 20. A first support seat 18 is provided on one side of the second support seat 21. A second stop 15 is provided at the end of the first support seat 18 away from the conveying device. The second stop 15 is pointed in shape, and the top of the first support seat 18 is parallel to the first support beam 14, that is, the top surface of the first support seat 18 is inclined downward. A first support plate 19 is vertically provided at the bottom of each second stop 15. The first support plate 19 is slidably connected to the first frame 4 through guide rails, allowing the first support plate 19 to move up and down reciprocally. Figure 6 and Figure 7 As shown, the first support plate 19 is installed on the first connecting rod 16. At least one first telescopic device 17 is vertically installed on the first connecting rod 16. The first telescopic device 17 is vertically downward and installed on the first frame 4. When the first telescopic device 17 extends and retracts, the first telescopic device 17 drives the first support seat 18 and the second stop block 15 to rise above the first support beam 14 or fall below the top of the first support beam 14.

[0032] The specific cooperation process between the limiting device and the third support plate 26 is as follows: First, the rod at the top of the first support beam 14 will roll downwards and come into contact with the first stop 20. In the initial state, the first stop 20 is located above the second stop 15 to prevent the downward rolling rod from directly contacting the second stop 15. Secondly, control the second telescopic device 22 to drive the second support seat 21 to move downward along the first support beam 14. At this time, the rod will also continue to roll downward with the first stop 20. When the rod is above the second stop 15, the second support seat 21 can be stopped. At this time, the first stop 20 is below the second stop 15. Then, the first telescopic device 17 is controlled to drive the first support seat 18 to rise. The second stop 15 is first inserted between the parallel rods to separate the two adjacent rods. Due to the presence of the second stop 15, only one rod can be located at the top of the first support seat 18. Finally, when the first support 18 rises to the same height as the third support plate 26, because the top of the first support 18 is tilted downwards, the rod located at the top of the first support 18 will roll onto the third support plate 26. Then, the third support plate 26 will slowly descend under the action of the third telescopic device 27, allowing the rod to rest gently on the grooved wheel 5. Figure 10 and Figure 11 A third stop 25 is provided at the top of the third support plate 26 away from the first frame 4 and the second frame 8. The third stop 25 is used to prevent the rod from falling off the third support plate 26.

[0033] Based on the above embodiments, the rod after being shot blasted by the shot blasting machine 6 moves along the conveying device to the second frame 8. The top of the second frame 8 is provided with multiple second support beams 13 whose inclination direction is opposite to that of the first support beam 14. The shot blasted rod rolls to the top of the second support beams 13. It should be noted that the top of the third support plate 26 located in front of the second frame 8 is an inclined surface, and this inclined surface is in the same direction as the second support beam 13. Therefore, when the third support plate 26 in front of the second frame 8 is raised, as... Figure 2 As shown, the rod will roll onto the second support beam 13. A second stop 10 is provided at the end of the second support beam 13 away from the conveying device. The second stop 10 is used to block the rod and prevent it from falling off the second support beam 13.

[0034] Based on the above embodiments, further optimization is possible. In practice, the loading and unloading device can be controlled by an automatic control system, such as the PLC control system most commonly used in industrial intelligent control, thereby automating the entire device. Figure 1 and Figure 2 As shown, a support frame 12 is provided at one end of the strip frame 1 away from the first frame 4. The support frame 12 is provided with a detector corresponding to the grooved wheel 5. The detector is used to monitor whether the rod after shot blasting has moved to the second frame 8.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
