Abstract
Description
Technical Field
[0001] This utility model relates to the field of track cleaning technology, and in particular to a laser welding machine track cleaning device. Background Technology
[0002] When the hot-rolled coil is uncoiled at the cold-rolled pickling inlet, iron oxide scale is produced on the surface due to the natural cooling of the hot-rolled coil. During the daily production process of the pickling mill, the unwinding of the strip inevitably brings some iron oxide scale from the upper part of the mill. As a single piece of equipment with extremely high precision requirements, the residual iron oxide scale on the laser welding machine carriage has a significant impact on the precision of the mill.
[0003] In the existing technology, when a laser welding machine travels on a dedicated track via bottom rollers, if a large amount of oxide scale accumulates on the track, the laser welding machine will crush the oxide on the track during its back-and-forth movement, causing uneven height on both sides of the laser welding machine. This leads to a decrease in the stability of the laser welding machine, directly affecting the weld quality and causing weld breakage. Therefore, it is necessary to propose a laser welding machine track cleaning device. Utility Model Content
[0004] This utility model mainly provides a laser welding machine track cleaning device that facilitates cleaning of the laser welding machine track and prevents the iron oxide scale on the track from affecting the stability of the laser welding machine during movement.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a laser welding machine track cleaning device, comprising a mounting plate, a mounting frame, and a transmission belt. An air pump is installed at the bottom inner part of the mounting plate. An air pipe is fixedly connected to the output end of the air pump. A connector is fixedly connected to the bottom end of the air pipe. A wind collector is fixedly connected to the front end of the connector. Multiple springs are fixedly connected at equal intervals between the mounting frame and the mounting plate. A column is installed on the inner side of the mounting frame. Multiple bristles are evenly distributed on the outer surface of the column. A rotating shaft is fixedly connected to the inner surface of the column. The rotating shaft rotatably passes through the mounting frame. A second pulley is fixedly connected to the outer surface of the rotating shaft. A motor is fixedly connected to the top of the mounting frame. A first pulley is fixedly connected to the output end of the motor.
[0006] Preferably, the top of the mounting frame is fixedly connected with multiple guide rods at equal intervals. The multiple guide rods slide through the mounting plate, so that when the mounting frame moves up and down, the multiple guide rods will slide synchronously in the mounting plate, which plays a guiding role and prevents the mounting frame from shifting position.
[0007] Preferably, the spring is located on the outside of the guide rod, and a limiting ring is fixedly connected to the outer surface of the guide rod near the top. This allows the guide rod to be limited by the limiting ring at its top when sliding within the mounting plate, preventing the guide rod from separating from the mounting plate and affecting its use.
[0008] Preferably, the first pulley and the second pulley are connected by a transmission belt, so that when the motor drives the first pulley, the second pulley will drive the shaft to rotate via the transmission belt.
[0009] Preferably, the top of the air collecting hood is symmetrically fixedly connected with connecting plates, and the top of both connecting plates is fixedly connected to the bottom of the mounting plate, so as to facilitate the connection of the air collecting hood and the mounting plate through the two connecting plates and fix it under the mounting plate.
[0010] Preferably, multiple air guide plates are equidistantly arranged on the inner surface of the air collecting hood, and the multiple air guide plates are all inclined, so that the airflow in the air collecting hood can be guided under the action of multiple inclined air guide plates, so that the high-speed airflow blown out can effectively blow the surface of the laser welding machine's travel track.
[0011] Preferably, multiple reinforcing plates are fixedly connected at equal intervals at the inner corners of the mounting plate. The reinforcing plates are triangular in shape, which helps to improve the structural strength of the mounting plate and prevent breakage at right-angle bends.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0013] 1. In this utility model, during the cleaning of the laser welding machine track, multiple springs are fixedly connected between the mounting frame and the mounting plate, which facilitates the multiple bristles on the column surface to closely adhere to the track surface. When the column is driven to rotate by the motor, the bristles on the column surface will rub against the track surface, which can throw off and clean the iron oxide scale on the track. When the air pump works in conjunction, it will send compressed gas into the air collection hood. Under the action of multiple inclined air guide plates, the airflow will blow in the direction of travel of the laser welding machine, which can blow away the residual iron oxide scale on the track, further improving the cleaning effect and preventing the laser welding machine from rolling iron oxide scale onto the track during travel, which would lead to poor stability of the laser welding machine and affect the welding quality.
[0014] 2. In this utility model, when the mounting bracket moves up and down under the action of the spring, the guide rod connected to its top will slide synchronously in the mounting plate, which plays a guiding and limiting role and prevents the position of the mounting bracket from shifting. By fixing multiple reinforcing plates at the inner corner of the mounting plate, the structural strength of the mounting plate can be improved, preventing the direct bend of the mounting part from breaking. It is highly practical. Attached Figure Description

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0022] Please see Figures 1-4 This utility model provides a technical solution: a laser welding machine track cleaning device, including a mounting plate 1, a mounting frame 8 and a transmission belt 17. An air pump 2 is installed at the bottom inner part of the mounting plate 1. An air pipe 3 is fixedly connected to the output end of the air pump 2. A connector 4 is fixedly connected to the bottom end of the air pipe 3. An air collector hood 5 is fixedly connected to the front end of the connector 4. Multiple springs 10 are fixedly connected at equal intervals between the mounting frame 8 and the mounting plate 1. A column 11 is installed on the inner side of the mounting frame 8. Multiple bristles 13 are evenly arranged on the outer surface of the column 11. A rotating shaft 12 is fixedly connected to the inner surface of the column 11. The rotating shaft 12 rotates through the mounting frame 8. A second pulley 18 is fixedly connected to the outer surface of the rotating shaft 12. A motor 15 is fixedly connected to the top of the mounting frame 8. A first pulley 16 is fixedly connected to the output end of the motor 15.
[0023] like Figures 1-2 As shown, multiple guide rods 9 are fixedly connected at equal intervals on the top of the mounting bracket 8. All guide rods 9 slide through the mounting plate 1, so that when the mounting bracket 8 moves up and down, the multiple guide rods 9 will slide synchronously in the mounting plate 1, which plays a guiding role and prevents the mounting bracket 8 from shifting position.
[0024] like Figures 1-2As shown, the spring 10 is located on the outside of the guide rod 9. A limit ring is fixedly connected to the outer surface of the guide rod 9 near the top. This allows the guide rod 9 to be limited by the limit ring at its top when it slides inside the mounting plate 1, preventing the guide rod 9 from separating from the mounting plate 1 and affecting its use.
[0025] like Figure 1 As shown, the first pulley 16 and the second pulley 18 are connected by a transmission belt 17, so that when the motor 15 drives the first pulley 16, the second pulley 18 will drive the rotating shaft 12 to rotate through the transmission belt 17.
[0026] like Figures 1-2 As shown, the top of the air collecting hood 5 is symmetrically fixedly connected with connecting plates 7. The top of both connecting plates 7 is fixedly connected to the bottom of the mounting plate 1, so that the air collecting hood 5 can be connected to the mounting plate 1 through the two connecting plates 7 and fixed below the mounting plate 1.
[0027] like Figure 1 As shown, multiple air guide plates 6 are equidistantly arranged on the inner surface of the air collecting hood 5. All the air guide plates 6 are inclined, which facilitates the airflow inside the air collecting hood 5 under the action of the multiple inclined air guide plates 6, so that the high-speed airflow blown out can effectively blow the surface of the laser welding machine's travel track.
[0028] like Figure 1 and Figure 4 As shown, multiple reinforcing plates 14 are fixedly connected at equal intervals at the inner corner of the mounting plate 1. The reinforcing plates 14 are triangular in shape, which helps to improve the structural strength of the mounting plate 1 and prevent breakage at the right-angle bend.
[0029] The usage and working principle of this device are as follows: When using the laser welding machine track cleaning device, two sets of such cleaning devices need to be installed, placed on both sides of the laser welding machine in the direction of travel. The mounting plate 1 is connected and fixed to the laser welding machine with bolts. Under the action of the rebound force of multiple springs 10, the multiple springs 10 will push the mounting frame 8 downward until the multiple bristles 13 on the outer surface of the column 11 abut against and adhere to the two tracks. When the laser welding machine travels, the motor 15 is started. The output end of the motor 15 will drive the first pulley 16 to rotate, which will drive the second pulley 18 through the transmission belt 17, so that the rotating shaft 12 will drive the column 1 1. The mounting bracket 8 rotates inside, causing multiple bristles 13 on its surface to rub and clean the track in the direction of the laser welding machine's movement. In conjunction with starting the air pump 2, the air pump 2 will draw in a large amount of external air, compress it, and send it into the air pipe 3. The air is then introduced into the air collection hood 5 through the connector 4. Under the action of multiple inclined air guide plates 6, the high-speed airflow in the air collection hood 5 can be guided, causing the airflow to blow in the direction of the laser welding machine's movement. This can blow away the residual iron oxide scale on the track, further improving the cleaning effect and preventing the laser welding machine from rolling the iron oxide scale onto the track during its movement, which would lead to a decrease in the stability of the laser welding machine and affect the welding quality.
[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
