Description

Technical Field

[0001] The utility model relates to the field of casting processing, in particular to a cleaning structure for a follow-up hood of a pouring processing robot. Background Technique

[0002] The main technological processes of casting include: metal melting, model manufacturing, pouring and solidifying, and demoulding and cleaning, etc. The main materials used in casting are cast steel, cast iron, casting non-ferrous alloys (copper, aluminum, zinc, lead, etc.), etc. The casting process of metal is to pour the molten metal into the pouring port of the casting mold, and then a formed workpiece can be obtained after cooling. During the pouring process, a gas hood is often used to collect the fumes and oil stains generated by pouring.

[0003] In the existing pouring technological process, in order to reduce the labor intensity of workers and also to avoid the safety hazards existing in the manual transfer of high-temperature molten metal during the pouring process, industrial robots are often used to transfer materials. Most of the gas hoods are fixedly installed at one end of the equipment, so that the high-temperature fumes generated during the movement of the robot arm during the pouring process of high-temperature molten metal cannot be effectively absorbed. Therefore, by installing the gas hood at one end of the transfer robot or the robotic arm, when the robot or the robotic arm moves within a certain range, the gas hood can move with the robot or the robotic arm, so as to collect the fumes generated during the process of the robot or the robotic arm transferring materials. Generally, a filter screen is arranged on one side of the opening of the gas hood to prevent the dust contained in the high-temperature fumes from entering the pipeline from the gas hood, thereby causing pipeline pollution and affecting the use. After long-term use, the oil stains of the high-temperature fumes are easily attached to one side of the filter screen, resulting in blockage, thereby affecting the gas collection effect of the filter screen and the gas hood. For this reason, this application proposes a cleaning structure for a follow-up hood of a pouring processing robot to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a cleaning structure for a follow-up hood of a pouring processing robot to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A cleaning structure for a follow-up hood of a pouring processing robot, including a gas hood body. A mounting cylinder communicating with the inside of the gas hood body is fixedly connected to the side of the gas hood body far away from the opening. A connecting rod is fixedly connected to the center position of the mounting cylinder close to the gas hood body. One side of the mounting cylinder is fixedly installed at one end of the robot body through a mounting plate and a plurality of bolts. A filter screen is fixedly installed on the side of the gas hood body close to the opening. The center positions of the connecting rod and the filter screen are respectively rotationally penetrated through the outside of a rotating shaft. An air flow fan is fixedly installed at the top of the rotating shaft. A cleaning component is fixedly connected to the bottom end of the rotating shaft and is arranged in a fitting manner with the bottom end of the filter screen. A liquid adding component is fixedly installed at the top of the gas hood body.

[0006] Preferably, the cleaning assembly includes a rotating block arranged horizontally and fixedly connected to the bottom end of the rotating shaft, and a cleaning brush is fixedly arranged at the top end of the rotating block and is in close contact with the bottom end of the filter screen.

[0007] Preferably, the liquid adding assembly includes a top block fixedly connected to the top end of the air collecting hood body, and a liquid injection threaded cylinder is threadedly penetrated through the center position of the top block.

[0008] Preferably, the bottom end of the liquid injection threaded cylinder is threadedly penetrated through the top end of the air collecting hood body and the bottom end of the liquid injection threaded cylinder extends into the air collecting hood body.

[0009] Preferably, a bottom block is fixedly connected to the outside of the liquid injection threaded cylinder inside the air collecting hood body, and a sponge block is fixedly arranged at the bottom end of the bottom block.

[0010] Preferably, a liquid injection channel is penetrated through the center position of the liquid injection threaded cylinder, and the bottom end of the liquid injection channel of the liquid injection threaded cylinder is in contact with one end of the sponge block. An adjusting block is fixedly sleeved at the top end of the liquid injection threaded cylinder.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] In the present utility model, an air collecting hood body that moves with it is arranged on one side of the robot main body to collect the flue gas generated during the material transfer process. The collected flue gas is sent out through a pipeline connected to one end of the installation cylinder. The high-temperature flue gas is collected from the opening side of the air collecting hood body and filtered by the filter screen. By arranging an air flow fan on the side close to the installation cylinder, the rotation of the air flow fan is driven by the flow of the air flow during the collection of the high-temperature flue gas, so that the rotating block is driven to rotate through the rotation of the rotating shaft. Further, the cleaning brush arranged at the top end of the rotating block and in close contact with the bottom end of the filter screen is used to clean the pollutants attached to the mesh holes of the filter screen to avoid mesh hole blockage. In order to improve the cleaning effect, a water-based cleaning liquid is injected into the liquid injection channel at the center position of the liquid injection threaded cylinder. The water-based cleaning liquid enters the sponge block on one side of the bottom block through the liquid injection channel. By rotating the adjusting block, the outer side of the liquid injection threaded cylinder is threadedly adjusted with the top block, so that the liquid injection threaded cylinder can drive the bottom block and the sponge block to move downward along the vertical direction, so that the sponge block presses against the top end of the filter screen, and the water-based cleaning liquid in the filter screen is squeezed down and falls on the filter screen, so as to clean the mesh holes of the filter screen in combination with the cleaning brush.

[0017] Embodiment 1

[0018] Please refer to Figure 1 - Figure 2 , a cleaning structure for a follow-up hood of a pouring processing robot shown in the figure, includes a gas collecting hood body 1. A mounting cylinder 3 communicating with the inside of the gas collecting hood body 1 is fixedly connected to the side of the gas collecting hood body 1 far away from the opening. And a connecting rod 2 is fixedly connected to the central position of the end of the mounting cylinder 3 close to the gas collecting hood body 1. One side of the mounting cylinder 3 is fixedly installed at one end of the robot body 5 through a mounting plate 4 and a plurality of bolts. And a filter screen 10 is fixedly installed on the side of the gas collecting hood body 1 close to the opening. The central positions of the connecting rod 2 and the filter screen 10 are respectively rotatably penetrated through the outside of a rotating shaft 6. And an air flow fan 7 is fixedly installed at the top of the rotating shaft 6. A cleaning component 8 is fixedly connected to the bottom end of the rotating shaft 6 and is arranged in a manner of being in contact with the bottom end of the filter screen 10. A liquid adding component 9 is fixedly installed at the top of the gas collecting hood body 1.

[0019] In this embodiment, the cleaning component 8 includes a horizontally arranged rotating block 81 fixedly connected to the bottom end of the rotating shaft 6. And a cleaning brush 82 in contact with the bottom end of the filter screen 10 is fixedly arranged at the top of the rotating block 81. The liquid adding component 9 includes a top block 91 fixedly connected to the top of the gas collecting hood body 1. And a liquid injection threaded cylinder 92 is threadedly penetrated through the central position of the top block 91. The bottom end of the liquid injection threaded cylinder 92 is threadedly penetrated through the top of the gas collecting hood body 1 and the bottom end of the liquid injection threaded cylinder 92 extends into the inside of the gas collecting hood body 1. A bottom block 93 is fixedly connected to the outside of the liquid injection threaded cylinder 92 located inside the gas collecting hood body 1. And a sponge block 94 is fixedly arranged at the bottom end of the bottom block 93. A liquid injection channel 921 is penetrated through the central position of the liquid injection threaded cylinder 92. And the bottom end of the liquid injection channel 921 of the liquid injection threaded cylinder 92 is in contact with one end of the sponge block 94.

[0020] Further, a gas collecting hood body 1 that moves with it is arranged on one side of the robot body 5 to collect the flue gas generated during the material transfer process. The collected flue gas is sent out through a pipeline connected to one end of the installation cylinder 3. The high-temperature flue gas is collected from the opening side of the gas collecting hood body 1 and filtered through the filter screen 10.

[0021] The working principle of the present utility model: A gas collecting hood body 1 that moves with it is arranged on one side of the robot body 5 to collect the flue gas generated during the material transfer process. The collected flue gas is sent out through a pipeline connected to one end of the installation cylinder 3. The high-temperature flue gas is collected from the opening side of the gas collecting hood body 1 and filtered through the filter screen 10. By arranging an air flow fan 7 on one side close to the installation cylinder 3, the flow of the air current during the collection of the high-temperature flue gas drives the air flow fan 7 to rotate. Thus, the rotating shaft 6 rotates to drive the rotating block 81 to rotate. Further, a cleaning brush 82 provided at the top of the rotating block 81 and fitting with the bottom end of the filter screen 10 is used to clean the pollutants attached to the mesh holes of the filter screen 10, avoiding the blockage of the mesh holes. To improve the cleaning effect, a water-based cleaning liquid is injected into the liquid injection channel 921 at the center position of the liquid injection threaded cylinder 92. The water-based cleaning liquid enters the sponge block 94 on one side of the bottom block 93 through the liquid injection channel 921 and is adsorbed. By rotating the adjusting block 95, the outer side of the liquid injection threaded cylinder 92 is thread-adjusted with the top block 91, so that the liquid injection threaded cylinder 92 can drive the bottom block 93 and the sponge block 94 to move downward along the vertical direction. Thus, the sponge block 94 is pressed against the top end of the filter screen 10, squeezing the water-based cleaning liquid in the filter screen 10 down onto the filter screen 10, and then combining with the cleaning brush 82 to clean the mesh holes of the filter screen 10.
