A mattress spring is installed inside the bag chamber 100. The welding strip 101 has two welding lines formed by multiple welding points 102, which are completed by the previous process.

[0003] To facilitate tearing the welding strip 101, an easy-tear welding line 103 needs to be formed between the two welding lines. Since the bag strip is made of soft material, it is easy to bend during the bag strip transportation process, which may cause the forming position of the easy-tear welding line 103 to shift. The easy-tear welding line 103 may hit the welding line formed by the welding point 102, causing damage to the bag body 100 of the bag chamber, which is a defect. Utility Model Content

Detailed Implementation

[0029] 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.

[0030] Example 1:

[0031] like Figure 2As shown, this embodiment discloses an easy-tear welding wire processing device for bagged spring strips, including a guide rod 1. A first movable plate 2 and a second movable plate 3 are slidably connected to the guide rod 1. A first fixed plate 11 is mounted on one axial end of the guide rod 1, and a first driving component 12 (a cylinder) is mounted on the first fixed plate 11. The output end of the first driving component 12 is connected to the first movable plate 2, enabling the first movable plate 2 to move along the axial direction of the guide rod 1. A second fixed plate 13 is mounted on the other axial end of the guide rod 1, and a second driving component 14 is mounted on the second fixed plate 13. The output end of the second driving component 14 is connected to the second movable plate 3, enabling the second movable plate 3 to move along the axial direction of the guide rod 1.

[0032] like Figure 2 As shown, the first movable plate 2 is equipped with a first welding blade plate 21, and the second movable plate 3 is equipped with a mold head plate 31, which is an ultrasonic welding mold head. Figure 2 , Figure 3 As shown, the first movable plate 2 is equipped with a third driving component 22, which is a cylinder. The output end of the third driving component 22 is connected to a second welding knife plate 221. The second welding knife plate 221 passes through the first welding knife plate 21.

[0033] like Figure 5 As shown, the first welding knife blade 21 and the second welding knife blade 221 are both vertically opposite to the die head plate 31. The second welding knife blade 221 has a second cutting edge 2211 on the side near the die head plate 31, as shown... Figure 7 As shown, the second cutting edge 2211 is elongated, and multiple second cutting edges 2211 are spaced apart along the length direction of the second welding knife plate 221, with the distance between two adjacent second cutting edges 2211 being less than or equal to 5 mm. The second welding knife plate 221 includes second welding knife plate end faces 2212 located at both ends in the length direction, and the second cutting edges 2211 located at both ends in the distribution direction of the second welding knife plate 221 extend in the length direction to the second welding knife plate end faces 2212.

[0034] like Figure 5 As shown, the die plate 31 includes a die plate end face 311 located at the top, and the second cutting edge 2211 approaches the die plate end face 311 to form an abutment, thereby enabling the material located between the two to complete ultrasonic welding.

[0035] The first welding blade plate 21 includes a first cutting edge 211, which is located on both sides of the second cutting edge 2211 along its length. Figure 4 As shown, multiple first cutting edges 211 are spaced apart along the length of the first cutting edge 211. For example... Figures 2-5As shown, the distribution direction of the first cutting edge 211 is parallel to the distribution direction of the second cutting edge 2211. The first cutting edge 211 and the end face 311 of the die plate approach each other to form an abutment, and the material located between them is ultrasonically welded.

[0036] like Figure 6 As shown, during use, the first cutting edge 211 abuts against the end face 311 of the die plate before the second cutting edge 2211 abuts against the end face 311 of the die plate. The first cutting edge 211 is used to weld and form ordinary weld points, while the second cutting edge 2211 is used to weld and form easy-tear welding rods. Due to the different materials of the first cutting edge 211 and the second cutting edge 2211, when they come into contact with the end face 311 of the die plate, assuming that the first cutting edge 211 and the second cutting edge 2211 are fixedly installed and welded simultaneously, it is difficult for the first cutting edge 211 to be flush with the second cutting edge 2211 so that they can abut against the end face 311 of the die plate together for welding. Therefore, the welding operations of the first cutting edge 211 and the second cutting edge 2211 are set to be performed in sequence.

[0037] Example 2:

[0038] like Figures 8-10 As shown, a bagged spring strip is processed using the easy-tear welding wire processing device for bagged spring strips in Embodiment 1. The bagged spring strip includes a bagged spring strip body 4, which is a continuous elongated strip and is composed of two layers of non-woven fabric joined together. The bagged spring strip body 4 includes bagged portions 42 spaced apart along its length and welded portions 41 located between adjacent bagged portions 42, such as... Figure 9 As shown, a cavity is formed inside the bag section 42 for installing mattress springs.

[0039] like Figure 10 As shown, before processing using the easy-tear welding line processing device for bag spring strips in Embodiment 1, the welding seal portion 41 is provided with at least one welding line formed by a plurality of first welding points 411, which are spaced apart along the width direction of the bag spring strip body 4. Preferably, the welding line formed by the first welding points 411 is configured as two parallel lines, located on both sides of the width direction of the welding seal portion 41.

[0040] The main body 4 of the bagged spring strip also includes multiple welding lines 413 and second welding points 412 located on both sides of the welding lines 413. The welding lines 413 are formed by welding the second cutting edge 2211 to the die plate 31. The welding lines 413 are easy-tear lines. The welding lines 413 are formed by multiple short welding lines distributed at intervals. The spacing between the short welding lines 413 matches the spacing between two adjacent second cutting edges 2211, which is also less than or equal to 5mm. At the same time, Figure 8As shown, the welding lines 413 located at both ends of the bag spring strip body 4 in the width direction extend to the corresponding end face of the bag spring strip body 4 in the width direction. That is, the short welding lines of the welding lines 413 penetrate the end face of the bag spring strip body 4 in the width direction, so as to facilitate tearing open the bag part 42 at the end.

[0041] Multiple second solder joints 412 are provided along the length direction parallel to the welding line 413, and the second solder joints 412 are located between the welding lines formed by the first solder joints 411 on both sides.

[0042] The second weld point 412 is formed by welding the first cutting edge 211 to the die plate 31. Since both the second weld point 412 and the first weld point 411 are used to splice the non-woven fabric layers on both sides to seal the bag chamber of the bagging section 42, and the weld line formed by the second weld point 412 is located on both sides of the weld line 413, if the weld line 413 is misaligned, such as... Figure 11 As shown, at this time, the welding line 413 is applied to the welding line formed by the first welding point 411. If there is only the welding line 413, it is easy to crack after the welding line 413 is formed, which will cause the bag part 42 to be damaged. However, the welding points 412 on both sides of the welding line 413 are added. The welding points 412 can play a protective role and prevent the bag part 42 from being damaged.

[0043] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
