DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0030] A welding strip straightening device according to an embodiment of the utility model is first described in detail below with reference to the accompanying drawings.

[0031] refer to Figure 1 , which shows a front view of a welding strip straightening device in some embodiments of the present utility model, such as Figure 1As shown, the welding strip straightening device of the embodiment of the utility model may include: two wire guide wheels 200, two straightening brackets 300 and a clamping mechanism 500. Among them, the two wire guide wheels 200 are arranged opposite to each other, and each wire guide wheel 200 is used to connect with the body 100 of the welding strip processing equipment; the two straightening brackets 300 are arranged opposite to each other between the two wire guide wheels 200, one end of the two straightening brackets 300 along the length direction is close to the corresponding wire guide wheels 200 and is respectively hinged to the body 100, and the other ends of the two straightening brackets 300 along the length direction are close to each other and there is a gap between them, and each straightening bracket 300 is respectively provided with a guide groove extending along its length direction, and the two guide grooves are located in the same vertical plane and their extension lines intersect. The clamping mechanism 500 is arranged above the gap between the two straightening brackets 300 and cooperates with the two straightening brackets 300 respectively. The welding strip 400 is arranged along two wire guide wheels 200 and two guide grooves and passes through the bottom of the clamping mechanism 500. The clamping mechanism 500 is used to push down the ends of the two straightening brackets 300 that are close to each other to swing up and down synchronously so that the clamping mechanism 500 can clamp or loosen the welding strip.

[0032] In this embodiment, when the welding tape 400 is straightened, the welding tape 400 to be straightened can first be passed from the left side into the guide groove on the wire guide wheel 200 and the straightening bracket 300 on the side, and then the welding tape 400 to be straightened is passed from the bottom of the clamping mechanism 500 and passed to the right into the guide groove on the right straightening bracket 300, and then the welding tape 400 to be straightened is led out from the wire guide wheel 200 on the side and connected to the rotatable take-up wheel for winding the welding tape 400. After the arrangement of the welding tape 400 is completed, the clamping mechanism 500 arranged above the gap between the two straightening brackets 300 can be controlled to extend downward to clamp the welding tape 400 between the two straightening brackets 300. Thus, the clamping mechanism 500 can apply external force to the welding tape 400 to straighten the side bending part or the flipping part on the welding tape 400. As the clamping mechanism 500 presses the welding strip 400 downward, the clamping mechanism 500 drives the two straightening brackets 300 to swing downward with the hinge points of the two straightening brackets 300 and the body 100 as the rotation center. Therefore, on the one hand, the two straightening brackets 300 can provide support for the welding strip 400, and improve the straightening effect of the clamping mechanism 500 on the welding strip 400. On the other hand, the two straightening brackets 300 swing downward synchronously with the downward pressure of the clamping mechanism 500, and the welding strips 400 on both sides of the clamping mechanism 500 are always at the same angle as the straightening brackets 300 on the corresponding sides, so that the welding strip 400 between the two straightening brackets 300 can be prevented from being excessively bent under the pressure of the clamping mechanism 500, and the welding strips 400 on both sides of the clamping mechanism 500 can also be evenly stressed.

[0033] refer to Figure 2, which shows a bottom view of a welding strip straightening device in some embodiments of the present utility model, such as Figure 2 As shown, the straightening bracket 300 of the embodiment of the utility model can include: a base plate 310, two guide rods 320 and two sets of fasteners 321. Among them, a waist hole 312 is respectively provided at both ends of the length direction of the base plate 310, and the length direction of each waist hole 312 is perpendicular to the length direction of the base plate 310; the two guide rods 320 are arranged side by side on the base plate 310, and the length direction of the two guide rods 320 is consistent with the length direction of the base plate 310, and a guide groove is formed between the two guide rods 320, and the guide groove is located above the two waist holes 312, and the two guide rods 320 can be moved along the length direction of the two waist holes 312 to adjust the distance between the two guide rods 320; the two ends of the two guide rods 320 in the length direction are respectively connected to the base plate 310 by a set of fasteners 321, and each set of fasteners 321 passes through a waist hole 312 corresponding to it.

[0034] In this embodiment, the distance between the two guide rods 320 can be adjusted along the length direction of the waist hole 312 according to the width of different types of welding strips 400, and the guide rods 320 can be fixed to the bottom plate 310 by passing the fasteners 321 through the waist hole 312. In this way, the guide groove can adapt to welding strips 400 of different widths, which can improve the applicability and application range of the straightening bracket 300 on the one hand, and on the other hand, the welding strip 400 can be prevented from shifting by limiting the entry of the welding strip 400 through the guide groove, and the side-bent welding strip 400 can be preliminarily straightened, thereby improving the straightening effect of the welding strip 400.

[0035] like Figure 1 and Figure 2 As shown, a rotating shaft 311 hinged to the machine body 100 is provided on the bottom plate 310, and a seat bearing matched with the rotating shaft 311 is provided on the machine body 100. Therefore, by providing the rotating shaft 311 at one end of the base 310 of each straightening bracket 300 close to the corresponding wire guide wheel 200, and hingedly connecting the rotating shaft 311 to the seat bearing, each straightening bracket 300 can be ensured to swing up and down better, and the welding belt 400 between the straightening bracket 300 and the wire guide wheel 200 can be better prevented from being excessively bent during the pressing process.

[0036] like Figure 1 and Figure 2 As shown, the clamping mechanism 500 includes: a driving member 510 and a clamping guide wheel 520. The driving member 510 is arranged above the gap between the two straightening brackets 300; the clamping guide wheel 520 is connected to the output end of the driving member 510, and the driving member 510 is used to drive the clamping guide wheel 520 to move up and down, and at the same time, the driving member 510 drives the ends of the two straightening brackets 300 that are close to each other to swing up and down synchronously so that the clamping guide wheel 520 loosens or clamps the welding strip 400.

[0037] In this embodiment, the wheel axis direction of the clamping guide wheel 520 is the same as the wheel axis direction of the two sets of wire guide wheels 200. When the welding strip 400 needs to be straightened, the driving member 510 can drive the clamping guide wheel 520 to move downward, and at the same time, the two straightening brackets 300 respectively swing downward with their respective rotation axes 311 as the rotation center, so that the clamping guide wheel 520 clamps the welding strip 400 at the gap between the two straightening brackets 300. Thus, by applying external force to the welding strip 400 through the clamping guide wheel 520, the side bending part or the flipping part on the welding strip 400 can be straightened.

[0038] like Figure 1 As shown, each straightening bracket 300 further includes: a connecting plate 330, the connecting plate 330 is located at one end of the bottom plate 310 close to the clamping mechanism 500, one end of the connecting plate 330 is hinged to the corresponding bottom plate 310, and the other end of the connecting plate 330 is hinged to the axle of the clamping guide wheel 520. In other words, as the driving member 510 drives the clamping guide wheel 520 to press down, the driving member 510 drives the two straightening brackets 300 to swing downward with their respective rotation axes 311 as the rotation center through the two connecting plates 330. Therefore, on the one hand, the straightening bracket 300 can provide support for the welding strip 400, and improve the straightening effect of the clamping mechanism 500 on the welding strip 400. On the other hand, since the two straightening brackets 300 can swing downward synchronously with the downward pressure of the clamping guide wheel 520, the welding strips 400 on both sides of the clamping mechanism 500 can always be at the same angle as the straightening brackets 300 on their respective corresponding sides, thereby preventing part of the welding strip 400 between the two straightening brackets 300 from being excessively bent under the pressure of the clamping mechanism 500, and at the same time, the welding strips 400 on both sides of the clamping mechanism 500 can be evenly stressed.

[0039] In one embodiment of the present invention, the driving member 510 may be a cylinder, and the driving member 510 is disposed on a fixed seat, and the fixed seat is used to be connected to the machine body 100. The output end of the driving member 510 faces downward and is connected to the guide wheel connecting bracket, and the pressing guide wheel 520 is rotatably disposed on the guide wheel connecting bracket. The power output of the cylinder is stable, so that the pressing guide wheel 520 can steadily apply pressure to the welding strip 400 to be straightened, thereby avoiding damage to the welding strip 400. In some other embodiments of the present invention, the driving member 510 may also be a power device such as an electric cylinder, which is not limited here.

[0040] In one embodiment of the utility model, a pressure sensor for detecting the thrust of the output end of the driving member 510 is provided. By providing a pressure sensor for detecting the thrust of the output end of the driving member 510, the thrust of the driving member 510 can be set according to different types of welding strips 400 and the degree of lateral bending of the welding strips 400. For example, the operator can adaptively adjust the air pressure of the cylinder according to different types of welding strips 400 and the degree of lateral bending of the welding strips 400. Thus, the applicability and application range are effectively improved.

[0041] like Figure 2 As shown, the pressing guide wheel 520 is provided with a first groove for accommodating the welding strip 400, and the first groove is an annular groove body surrounding the circumference of the pressing guide wheel 520. In this embodiment, the first groove can limit and block the welding strip 400, so that the straightening effect is better.

[0042] like Figure 1 and Figure 2 As shown, the gap between the two straightening brackets 300 is greater than or equal to the diameter of the pressing guide wheel 520. Therefore, the pressing guide wheel 520 can be fully moved downward through the gap between the two straightening brackets 300, thereby improving the straightening effect of the welding strip 400.

[0043] like Figure 2 As shown, each wire guide wheel 200 is provided with a second groove for accommodating the welding strip 400, and the second groove is an annular groove body surrounding the circumference of the wire guide wheel 200. The second groove can limit and block the welding strip 400, which can prevent the welding strip 400 on the wire guide wheel 200 from slipping off on the one hand, and can make the straightening effect better on the other hand.

[0044] In summary, the welding strip 400 straightening device of the embodiment of the utility model guides and adjusts the welding strip 400 through two wire guide wheels 200, and at the same time presses the welding strip 400 between the two straightening brackets 300 downward through the clamping mechanism 500, so that an external force can be applied to the welding strip 400 to straighten the side bending part or the flipping part of the welding strip 400. In addition, during the downward pressing process of the clamping mechanism 500, the clamping mechanism 500 will also drive the two straightening brackets 300 to swing downward synchronously, so that the part of the welding strip 400 between the two straightening brackets 300 is always level with the upper surface of the two straightening brackets 300 respectively. Therefore, on the one hand, excessive bending of the welding strip 400 between the two straightening brackets 300 can be avoided, and on the other hand, the welding strip 400 on both sides of the clamping mechanism 500 can also be subjected to uniform force.
