[0003] However, traditional welding and straightening equipment lacks slag removal devices and requires regular manual cleaning. If this is not done promptly, slag and flux will spread throughout the entire conveyor roller conveyor. Furthermore, the roller conveyor is equipped with piping and roller support systems, making secondary cleaning extremely difficult. This accumulated slag can affect the normal operation of the equipment and even pose a safety hazard. Utility Model Content

When the H-steel enters, the friction drive wheel and rotating arm, impacted by the web, tend to rotate relative to the guide plate. This rotational force causes the friction drive wheel to press more tightly against the web, achieving a self-locking compression mechanism. Even after prolonged and repeated impacts, the friction drive wheel will not separate from the web. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the embodiments described are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0030] like Figure 1 、 Figure 2 and Figure 3 A self-driven welding slag cleaning device for assembly welding and straightening equipment includes a base body, a friction driving wheel 7 and a rotating sweeping disc 8.

[0031] The base includes a column 1, a lifting arm 3, a guide plate 5, and a rotating arm 6. The column 1 is fixed, the lifting arm 3 is mounted on the column 1 and can be raised and lowered relative to the column 1, the guide plate 5 is horizontally slidably connected to the lifting arm 3, the rotating arm 6 is horizontally rotatably connected to the lifting arm 3, and the friction driving wheel 7 and the rotating sweeping disc 8 are mounted on the rotating arm 6.

[0032] The friction driving wheel 7 is used to contact the welded web 9 and rotate under the action of the web 9. The rotating sweeping disc 8 is located at the weld seam between the welded web 9 and the wing plate 10. The friction driving wheel 7 is connected to the rotating sweeping disc 8 through a transmission mechanism. Specifically, Figure 2 and Figure 3 The transmission mechanism includes a first gear 11 connected to the friction driving wheel 7 and a second gear 12 connected to the rotating sweeping disc 8. The first gear 11 has a larger number of teeth than the second gear 12, thereby enabling the rotating sweeping disc 8 to rotate faster and improving the cleaning effect. In this embodiment, the gear ratio between the first gear 11 and the second gear 12 is 2:1. The transmission mechanism can also be a transmission belt or other structure.

[0033] Specifically, if Figure 5 The column 1 is provided with an external threaded portion, the through hole at the outer end of the lifting arm 3 is sleeved on the external threaded portion, the inner side of the through hole is provided with a protrusion, and the external threaded portion is provided with a groove, and the two realize vertical sliding fit. Figure 4 The lifting arm 3 is fixed on the column 1 through two sets of upper and lower fastening nuts 2 that cooperate with the external threaded part.

[0034] like Figure 2 and Figure 3 The guide plates 5 are provided in two sets, one above the other, located on either side of the inner end of the lifting arm 3 and the outer end of the rotating arm 6. In this embodiment, the guide plates 5 are provided with linear slots 5-2. The two sets of guide plates 5 and the lifting arm 3 are connected horizontally and slidably by a first fastener that passes through the linear slots 5-2 and the lifting arm 3. The first fastener is only used for sliding connection and is not tightened during normal operation.

[0035] Furthermore, if Figure 4The lifting arm 3 is provided with a vertical first support plate 3-1, the guide plate 5 is provided with a vertical second support plate 5-3, and a distance adjustment device 4 is provided between the first support plate 3-1 and the second support plate 5-3. The distance adjustment device 4 is provided with an elastic buffer device. Specifically, the distance adjustment device 4 includes a regulator composed of a fixedly connected first threaded rod 4-1 and a sleeve 4-2, and also includes a clamping rod composed of a fixedly connected second threaded rod 4-5 and a sliding shaft 4-4. The first threaded rod 4-1 cooperates with the threaded hole on the second support plate 5-3, the second threaded rod 4-5 cooperates with the threaded hole on the first support plate 3-1, and the sliding shaft 4-4 slides in cooperation with the inner hole of the sleeve 4-2. The compression spring 4-3 serving as the elastic buffer device is located in the inner hole of the sleeve 4-2 and its outer end contacts the sliding shaft 4-4.

[0036] As an optional implementation, the distance adjustment between the guide plate 5 and the lifting arm 3 can also be achieved manually or in other ways.

[0037] Furthermore, if Figure 2 and Figure 3 The guide plate 5 is further provided with an arc groove 5-1, the center of which coincides with the axis of the horizontal rotation connection between the guide plate 5 and the rotating arm 6. The guide plate 5 and the rotating arm 6 are further connected by a second fastener passing through the arc groove 5-1.

[0038] Furthermore, if Figure 2 The rotation axis of the friction driving wheel 7, the rotation axis of the rotating sweeping disc 8, and the axis of the horizontal rotation connection between the guide plate 5 and the rotating arm 6 are located in the same vertical plane. The angle between the vertical plane and the normal plane of the conveying direction of the web 9 is 12-18 degrees, preferably 15 degrees, and the rotation axis of the friction driving wheel 7 is located on the side of the guide plate 5 close to the conveying starting end of the web 9.

[0039] In order to realize the centralized recovery of welding slag, a collection box is further provided below the rotating sweeping disc 8 .

[0040] Before work, first loosen the fastening nut 2 to adjust the height of the lifting arm 3, and tighten the fastening nut 2 to fix the height of the lifting arm 3. Then loosen the second fastener to adjust the angle of the rotating arm 6. After tightening the second fastener, rotate the handwheel at the end of the first threaded rod 4-1 (keep the first fastener loosened) to adjust the horizontal position of the guide plate 5 relative to the lifting arm 3. When the friction driving wheel 7 contacts the web 9, rotate the handwheel at the end of the second threaded rod 4-5 to change the compression amount of the compression spring 4-3, and accurately adjust the clamping force between the friction driving wheel 7 and the web 9. The preparation work is now completed.

[0041] When the web 9 and the wing plate 10 are transported forward, the friction driving wheel 7 will rotate under the friction of the web 9, and then drive the rotary sweeping disc 8 to rotate through the first gear 11 and the second gear 12 to realize the automatic cleaning function.

[0042] When the end of the web 9 hits the friction driving wheel 7, Figure 2 As shown, the rotating arms 6 on the left and right sides have a tendency to rotate clockwise / counterclockwise along the arc groove 5-1 respectively. This tendency will make the friction driving wheels 7 on both sides closer to the web 9, thereby avoiding the friction driving wheels 7 from being separated from the web 9 due to collision, resulting in failure of the cleaning function.

[0043] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. The scope of the present invention is defined by the claims rather than the above description.
