Description

Technical Field

[0001] This utility model relates to the field of rust removal technology, specifically an automatic shot blasting rust removal production line for H-beams. Background Technology

[0002] H-beams are an economical and efficient structural steel profile with optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio, named for their resemblance to the letter "H". They are widely used in construction, bridges, machinery manufacturing, the automotive industry, and many other fields. In construction, H-beams are often used as structural components such as steel beams and columns in large factories, stadiums, and high-rise buildings. However, during processing, H-beams often have numerous burrs and rust residues on their surface, which can affect the integrity and appearance of parts. Therefore, an automatic shot blasting production line is generally needed to treat the surface of H-beams to strengthen the workpiece. Regarding the aforementioned related technologies, the applicant proposes an automatic shot blasting production line for H-beams. During operation, H-beams are systematically transported into the processing chamber via a stable conveyor belt. The shot blasting unit inside the processing chamber then operates, ejecting steel shot at high speed and pressure. These high-speed steel shots impact the surface of the H-beams, effectively removing rust through their powerful impact. However, after the steel shot completes its rust removal task, its surface will inevitably be contaminated with a large amount of iron filings. When these iron-filament-contaminated steel shot are recycled and reused, the iron filings will participate in subsequent processing along with the steel shot, causing scratches on the workpiece surface and reducing the processing quality of the workpiece. Utility Model Content

[0003] The purpose of this utility model is to provide an automatic shot blasting and rust removal production line for H-beams, in order to solve the problem mentioned in the background art that after the steel shot completes the rust removal task, its surface will inevitably be contaminated with a large amount of iron filings. When these steel shot contaminated with iron filings are recycled and reused, the iron filings will participate in the subsequent processing along with the steel shot, which will cause scratches on the surface of the workpiece and reduce the processing quality of the workpiece.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic shot blasting and rust removal production line for H-beams, comprising a conveyor belt body and a recycling mechanism. The recycling mechanism is located at the bottom end of the conveyor belt body and includes a recycling box located in the middle part of the bottom end of the conveyor belt body. Support seats are provided at the bottom of both ends of the recycling box, and springs are provided at the top of the support seats. Movable frames are provided at the top of the springs, and the springs drive the movable frames to move up and down. A filter screen is provided inside the movable frames. Equipment boxes are provided at the top of both ends of the recycling box, and electric push rods are provided inside the equipment boxes.

[0005] By adopting the above technical solution, the electric push rod can push the movable frame downward to compress the spring. Then, the electric push rod moves upward, and the spring's rebound can cause the movable frame to shake, which in turn causes the steel shot on the filter screen to shake. This allows the metal debris on the outside of the steel shot to fall into the recycling bin, effectively improving the practicality of the device.

[0006] Preferably, a processing box is provided at the top of the conveyor belt body, and inlet and outlet are provided at both ends of the processing box, with elastic baffles provided on both sides inside the inlet and outlet.

[0007] By adopting the above technical solution, it is easy to block falling steel shot.

[0008] Preferably, the recycling bin has a hinged door on one side, and a handle is provided on the outside of the door.

[0009] By adopting the above technical solution, it is convenient for staff to collect the steel shot inside the recycling bin.

[0010] Preferably, the recycling bin has sliding grooves at both ends, and the movable frame is slidably disposed inside the sliding grooves.

[0011] By adopting the above technical solution, the stability of the moving frame can be improved.

[0012] Preferably, the output end of the electric push rod is provided with a rubber pad, and the output end of the electric push rod is located at the top of the movable frame.

[0013] By adopting the above technical solution, the output end of the electric linear actuator can be easily protected, minimizing damage to the output end of the electric linear actuator when the movable frame moves upward.

[0014] Preferably, the top of the processing box is provided with an accessory box, and the top of the accessory box has a feeding port.

[0015] By adopting the above technical solution, steel shot can be added to the inside of the parts box.

[0016] Preferably, a material conveying pipe is provided through the bottom of the accessory box, which extends into the interior of the processing box, and a control valve is provided on the outside of the material conveying pipe.

[0017] By adopting the above technical solution, steel shot can be transported conveniently.

[0018] Preferably, shot blasting rust remover bodies are provided on the upper sides of both sides inside the processing box, and the bottom end of the conveying pipe is connected to the input end of the shot blasting rust remover body.

[0019] By adopting the above technical solution, steel shot can be ejected at high speed through the main body of the shot blasting rust remover. These high-speed flying steel shot impacts the surface of the H-beam, effectively removing rust from the surface of the H-beam using its powerful impact force.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] The device is equipped with a conveyor belt, a recycling mechanism, a recycling bin, and a filter screen. During operation, the steel shot falls directly onto the filter screen, which filters the shot, allowing external debris to fall to the bottom of the recycling bin. An electric push rod moves the movable frame downwards, compressing a spring. The push rod then moves the frame upwards, and the spring's rebound causes the movable frame to vibrate, shaking the steel shot on the filter screen. This ensures that all external metal debris falls into the recycling bin, effectively improving the device's practicality. Attached Figure Description

[0027] 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.

[0028] Example 1

[0029] Please see Figures 1 to 4 This embodiment provides a technical solution: an automatic shot blasting and rust removal production line for H-beams, including a conveyor belt body 1 and a recycling mechanism 2. The recycling mechanism 2 is located at the bottom end of the conveyor belt body 1 and includes a recycling box 202 fixedly connected to the middle part of the bottom end of the conveyor belt body 1. The recycling box 202 can collect falling steel shot. Support seats 206 are fixedly connected to the lower ends of both ends of the inside of the recycling box 202. The support seats 206 can provide load-bearing capacity. A spring 205 is fixedly connected to the top of the support seat 206, and a movable frame 207 is fixedly connected to the top of the spring 205. The elastic potential energy of the spring 205 can drive the movable frame 207. The movable frame 207 moves up and down, and a filter screen 203 is fixedly connected inside. The filter screen 203 can filter the steel shot, allowing the debris on the outside of the steel shot to fall directly into the bottom of the recycling box 202. Equipment boxes 204 are fixedly connected to the top of both ends of the recycling box 202. An electric push rod 208 is fixedly connected inside the equipment box 204. A rubber pad is fixedly connected to the output end of the electric push rod 208 to protect the output end of the electric push rod 208 and avoid damage to the output end of the electric push rod 208 when the movable frame 207 moves upward. The output end of the electric push rod 208 is located at the top of the movable frame 207.

[0030] The effect achieved by the entire embodiment is as follows: by operating the electric push rod 208, the movable frame 207 can be pushed downward, which can compress the spring 205. Then, by using the electric push rod 208 to move upward, the spring 205 can be used to make the movable frame 207 shake, which can make the steel shot on the filter screen 203 shake. This allows the metal debris on the outside of the steel shot to fall into the recycling box 202, effectively improving the practicality of the device.

[0031] Example 2

[0032] A door 201 is hinged to one side of the recycling bin 202, which facilitates the collection of steel shot inside the recycling bin 202. A handle is fixedly connected to the outside of the door 201. Sliding grooves are provided at both ends inside the recycling bin 202. The movable frame 207 is slidably disposed inside the sliding groove, which can improve the stability of the movable frame 207 when it moves.

[0033] The effect achieved by the entire second embodiment is that after the device has finished working, opening the box door 201 makes it convenient for staff to collect the steel shot inside the recycling box 202.

[0034] Example 3

[0035] A processing box 4 is fixedly connected to the top of the conveyor belt body 1. The processing box 4 provides load-bearing capacity. Both ends of the processing box 4 have inlets and outlets. Elastic baffles 3 are fixedly connected to both sides inside the inlets and outlets to easily block falling steel shot. A parts box 5 is fixedly connected to the top of the processing box 4 for convenient storage of steel shot. The top of the parts box 5 has a feeding port. A conveying pipe 7 is installed through the bottom of the parts box 5, extending into the interior of the processing box 4. A control device is installed on the outside of the conveying pipe 7. The upper sides of both sides of the processing box 4 are fixedly connected to the shot blasting rust remover body 6. The bottom end of the conveying pipe 7 is connected to the input end of the shot blasting rust remover body 6. By opening the control valve, the steel shot inside the accessory box 5 can be transported into the shot blasting rust remover body 6. The shot blasting rust remover body 6 is existing technology. It works by using the drive motor inside the shot blasting rust remover body 6, which can drive the internal impeller to rotate at high speed and throw the shot onto the H-beam inside the processing box 4 to remove the rust on the surface of the H-beam.

[0036] The overall effect of Embodiment 3 is as follows: by utilizing the operation of the shot blasting rust remover body 6, steel shot can be ejected at high speed. These high-speed flying steel shot impacts the surface of the H-beam, effectively removing rust from the surface of the H-beam using its powerful impact force.

[0037] Working principle: First, the power is turned on, and the conveyor belt body 1 is started using the control switch. The H-beams on the conveyor belt body 1 can be transported and moved into the processing box 4. The shot blasting body 6 is then used to spray steel shot at high speed. These high-speed flying steel shot impacts the surface of the H-beams, effectively removing rust from the surface of the H-beams using their powerful impact force.

[0038] Finally, the falling steel shot falls directly onto the filter screen 203, which filters the steel shot, allowing the external debris to fall directly into the bottom of the recycling bin 202. Then, the operation of the electric push rod 208 pushes the movable frame 207 downward, compressing the spring 205. Subsequently, the electric push rod 208 moves upward, and the rebound of the spring 205 causes the movable frame 207 to shake, which in turn causes the steel shot on the filter screen 203 to shake. This ensures that the external metal debris of the steel shot falls into the recycling bin 202, effectively improving the practicality of the device.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
