Description

Technical Field

[0001] This utility model relates to the field of steel structure shot blasting machines, and in particular to an automated steel structure shot blasting machine. Background Technology

[0002] An automated steel structure shot blasting machine is a large-scale piece of equipment specifically designed for the surface treatment of steel structures. It uses high-speed thrown steel shot to strike the surface of steel to remove rust, scale, weld spatter, and other contaminants, while also increasing the surface roughness of the steel to improve its coating quality and corrosion resistance.

[0003] The working principle of an automated steel structure shot blasting machine is to use one or two electric shot blasters to throw steel shot at high speed to impact the workpiece. The thrown steel shot and the large amount of dust generated are surrounded by a local sealing device. The steel shot is recovered into the shot storage box by rebound and refraction and is recycled. The dust is drawn back to the equipment's built-in dust collector for purification through negative pressure.

[0004] In the actual use of automated steel structure shot blasting machines, the material to be polished comes into contact with the inner wall of the channel as it enters the polishing chamber. Due to burrs that may exist on the material surface, these burrs can easily damage the inner wall when rubbing against it. This damage not only reduces the durability of the inner wall but may also cause problems during the polishing process.

[0005] After the inner wall is damaged, its surface becomes rough, making it prone to accumulating dust particles and other debris. This accumulated debris can affect the quality of subsequent polishing. For example, dust particles may adhere to the surface of the material to be polished, leading to uneven polishing or scratches. In addition, debris may interfere with the normal operation of the shot blasting machine, reducing polishing efficiency. Utility Model Content

[0006] The main objective of this invention is to provide an automated steel structure shot blasting machine that can effectively solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] An automated steel structure shot blasting machine includes a shot blasting machine body, a shot conveying pipe, a dust collector, a dust extraction pipe, a connecting pipe, a dust removal pump, and a material pipe. Two of the material pipes are installed at the inlet and outlet of the shot blasting machine body. The shot conveying pipe is connected to the shot blasting chamber of the shot blasting machine body to realize the conveying of shot. The dust collector is installed at the rear end of the shot blasting machine body and is connected to the material pipe through the dust extraction pipe. The dust removal pump is connected to the dust collector through the connecting pipe.

[0009] A support frame is installed at the lower end of the material pipeline, and a vibrator is installed inside the support frame. A buffer base is installed at the lower end of the support frame. The vibrator drives the support frame and its material pipeline to vibrate, causing the impurity particles in the shot blasting process inside the material pipeline to vibrate, and then the dust is extracted through the dust extraction pipeline.

[0010] The material pipeline has a semi-circular plate at the bottom of the opening, and a connecting cylinder is connected to the semi-circular plate by a fixed rod. A limit rod is installed inside the connecting cylinder, and a guide roller is sleeved on the limit rod. The material to be polished passes through the guide roller and extends into the shot blasting chamber of the shot blasting machine, so as to realize the polishing of the material to be polished and its guiding operation.

[0011] In an optional embodiment of this application, a buffer sleeve is installed at the tail end of the connecting cylinder, and a through groove is provided on the side wall of the buffer sleeve. A buffer pulley is installed between the two through grooves, and the buffer pulley contacts the inner wall of the material pipeline.

[0012] In an optional embodiment of this application, the buffer sleeve is designed in the shape of an "I" and multiple round holes are opened at both ends of the buffer sleeve. The buffer sleeve is connected to the connecting cylinder by bolts, and multiple through grooves and buffer pulleys are distributed in a ring on the buffer sleeve.

[0013] In an optional embodiment of this application, the buffer pulley includes a bracket, a buffer wheel, and a rotating shaft. The bracket is welded and fixed to the buffer sleeve, and the buffer wheel is connected to the bracket through the rotating shaft. The outer part of the buffer wheel is a buffer rubber wheel.

[0014] In an optional embodiment of this application, the connecting cylinder and the guide roller are connected by a through channel, the material to be polished is inserted into the through channel and contacts the guide roller, and the inner edge of the guide roller is designed with an arc shape;

[0015] In an optional embodiment of this application, the dust extraction pipe is fixed to the upper opening of the material pipe by bolts, a buffer sealing strip is provided at the connection between the dust extraction pipe and the material pipe, and the support frame is welded and fixed to the material pipe;

[0016] In an optional embodiment of this application, a limiting strip, a buffer spring, and a limiting post are provided at the connection between the buffer base and the support frame. The limiting strip is fixed on the buffer base and the support frame, and the limiting post is fixed on the limiting strip by a nut. The buffer spring is sleeved on the limiting post, and a ring is welded to the upper and lower ends of the buffer spring. The ring slides up and down along the limiting post.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The combination of the connecting cylinder and the guide roller ensures precise guidance and smooth passage of the material to be polished. The inner edge of the guide roller is designed with an arc shape, which reduces material damage during the polishing process and improves polishing efficiency.

[0019] The buffer sleeve and its buffer pulleys provide additional cushioning and stability for the shot blasting machine. The buffer sleeve adopts an "I"-shaped design, which is structurally robust. Through multiple through grooves and annularly distributed buffer pulleys, it effectively reduces the vibration of the shot blasting machine during operation and reduces potential damage caused by vibration.

[0020] The design of the buffer pulley also improves the durability of the pulley. The use of buffer rubber wheels reduces wear on other parts of the shot blasting machine and extends the service life of the equipment. Attached Figure Description

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] like Figure 1 - Figure 5As shown, an automated steel structure shot blasting machine mainly consists of a shot blasting machine body 1, a shot conveying pipe 2, a dust collector 3, a dust extraction pipe 4, a connecting pipe 5, a dust pump 6, and a material pipe 7. Two material pipes 7 are installed at the inlet and outlet positions of the shot blasting machine body 1 to ensure smooth shot delivery. The shot conveying pipe 2 is closely connected to the shot blasting chamber of the shot blasting machine body 1, further optimizing the shot delivery process. The dust collector 3 is installed at the rear end of the shot blasting machine body 1 and connected to the material pipe 7 via the dust extraction pipe 4 to achieve effective dust removal. The dust pump 6 is connected to the dust collector 3 via the connecting pipe 5, ensuring the efficient operation of the entire system.

[0029] A support frame 17 is installed at the lower end of the material pipe 7. A vibrator 18 is installed inside the support frame 17 to enhance the vibration effect of the material pipe 7. A buffer base 19 is also installed at the lower end of the support frame 17. The vibrator 18 drives the support frame 17 and the connected material pipe 7 to vibrate, so that the impurity particles in the shot blasting inside the material pipe 7 are effectively vibrated and effectively dusted through the dust extraction pipe 4, thereby keeping the shot blasting machine clean and operating efficiently.

[0030] A semi-circular plate 8 is provided at the lower part of the opening of the material pipe 7, and the semi-circular plate 8 is connected to the connecting cylinder 10 by a fixing rod 9. A limiting rod 15 is installed inside the connecting cylinder 10, and a guide roller 16 is sleeved on the limiting rod 15. After the material to be polished passes through the guide roller 16, it extends into the shot blasting chamber of the shot blasting machine body 1, thereby realizing the polishing and guiding operation of the material and ensuring the accuracy and efficiency of the polishing process.

[0031] A buffer sleeve 11 is installed at the tail end of the connecting cylinder 10, and a through groove 12 is opened on the side wall of the buffer sleeve 11. A buffer pulley 13 is installed between the two through grooves 12. The buffer pulley 13 contacts the inner wall of the material pipe 7, providing additional buffering and stability for the entire shot blasting machine.

[0032] The buffer sleeve 11 adopts an "I"-shaped design with multiple round holes at both ends, and is connected to the connecting sleeve 10 by bolts to ensure the stability of the structure. Multiple through grooves 12 and buffer pulleys 13 are distributed in a ring on the buffer sleeve 11, making the entire shot blasting machine run more smoothly and reducing potential damage caused by vibration.

[0033] The buffer pulley 13 consists of a bracket, a buffer wheel, and a rotating shaft. The bracket is welded and fixed to the buffer sleeve 11, and the buffer wheel is connected to the bracket through the rotating shaft. The outer part of the buffer wheel is a buffer rubber wheel. This design not only improves the durability of the pulley, but also reduces the wear on other parts of the shot blasting machine.

[0034] A through-channel 14 connects the connecting cylinder 10 and the guide roller 16. The material to be polished is inserted into the through-channel 14 and comes into contact with the guide roller 16. The inner edge of the guide roller 16 is arc-shaped to ensure smooth passage of the material and reduce damage to the material during the polishing process.

[0035] The dust extraction pipe 4 is bolted to the upper opening of the material pipe 7. A buffer sealing strip is provided at the connection between the dust extraction pipe 4 and the material pipe 7 to prevent dust leakage and ensure a clean working environment. The support frame 17 is welded to the material pipe 7 to ensure the structural stability of the entire shot blasting machine.

[0036] The connection between the buffer base 19 and the support frame 17 is equipped with a limiting strip, a buffer spring, and a limiting post. The limiting strip is fixed to the buffer base 19 and the support frame 17, the limiting post is fixed to the limiting strip by a nut, and the buffer spring is sleeved on the limiting post. Rings are welded to the upper and lower ends of the buffer spring, and the rings slide up and down along the limiting post. This design provides additional cushioning and protection for the shot blasting machine, ensuring its stability and durability during long-term operation.

[0037] Ensure all equipment components are correctly installed and connected. Check that the support frame 17 of the material pipeline 7 is securely installed and ensure that the vibrator 18 is functioning properly. Confirm that the limiting strip, buffer spring, and limiting post at the connection between the buffer base 19 and the support frame 17 are correctly installed. Start the vibrator 18 to vibrate the material pipeline 7, enhancing the vibration effect during material conveying. Start the shot blasting chamber of the shot blasting machine, ensuring that the shot conveying pipeline 2 is tightly connected to the shot blasting chamber to optimize the shot blasting conveying process.

[0038] The material to be polished is inserted into the through-pass channel 14 of the connecting cylinder 10 and comes into contact with the guide roller 16. After passing through the guide roller 16, the material is inserted into the shot blasting chamber of the shot blasting machine body 1 for polishing and guidance. Inside the shot blasting chamber, the material undergoes shot blasting treatment, and surface impurities and rust are effectively removed. During the shot blasting process, impurity particles in the shot blasting material pipe 7 are vibrated by the vibrator 18 and effectively dusted through the dust extraction pipe 4.

[0039] Dust collector 3 is connected to material pipeline 7 via dust extraction pipe 4 to achieve effective dust removal. Dust pump 6 is connected to dust collector 3 via connecting pipe 5 to ensure efficient operation of the entire system and maintain the cleanliness and high efficiency of the shot blasting machine. Buffer pulley 13 is connected to the bracket via a rotating shaft. The outer surface of the buffer pulley is a buffer rubber wheel to reduce wear on other parts of the shot blasting machine. Multiple through slots 12 and buffer pulley 13 are distributed in a ring on the buffer sleeve 11, making the shot blasting machine run more smoothly and reducing potential damage caused by vibration.

[0040] After shot blasting, turn off vibrator 18 and the shot blasting chamber of the shot blasting machine. Inspect and clean residual shot and dust from material pipe 7 and dust extraction pipe 4 to ensure the cleanliness of the equipment and its effectiveness for the next use. Regularly inspect and maintain all parts of the equipment to ensure that the connections are secure and that vibrator 18 and dust collector 3 are functioning properly.
