[0013] The other end of the second connecting rod faces away from the bag clamp in the material packaging sewing equipment.

[0014] Furthermore, the second rectangular tube and the third rectangular tube are arranged parallel to each other and both are arranged perpendicular to the first rectangular tube;

[0015] The other ends of the second and third rectangular tubes are respectively used to connect with the connecting surfaces of the upper and lower support bag rods, which are the sides of the upper and lower support bag rods that are close to and parallel to the first rectangular tube.

[0016] Furthermore, the other end of the second rectangular tube is welded to the connecting surface of the upper support bag rod;

[0017] The other end of the third rectangular tube is welded with a fixing plate, which is connected to the connecting surface of the lower support bag rod by bolts.

[0018] Furthermore, the first connecting rod is initially positioned vertically, and the second connecting rod is positioned perpendicular to the first connecting rod.

[0019] The third connecting rods in the two bag-holding rod bodies are inclined towards each other, and the distance between the upper ends of the third connecting rods in the two bag-holding rod bodies is smaller than the distance between the lower ends.

[0020] Furthermore, the first and third connecting rods are both square tubes, while the second connecting rod is a round tube.

[0021] Furthermore, the side wall of the first connecting rod is provided with a plurality of locking holes, and the plurality of locking holes are evenly distributed along the length direction of the first connecting rod;

[0023] Furthermore, the locking opening is a rectangular opening, and the extending direction of the rectangular opening is perpendicular to the extending direction of the first connecting rod.

[0024] The beneficial effects of this utility model are:

[0025] 1. The connector of this utility model is composed of a first rectangular tube, a second rectangular tube and a third rectangular tube. The connector has good rigidity and stability. When connecting the upper support bag rod and the lower support bag rod, the connection stability between the upper support bag rod and the lower support bag rod and the connector is higher. It is not easy to displace under vibration conditions, thus ensuring the accuracy of the seam.

[0026] 2. This utility model uses a fixed plate as the connecting part between the third rectangular tube and the lower support bag rod, which can further increase the connection area and further improve the connection stability.

[0027] 3. This utility model avoids interference between the bag-holding rod and the bag-packing robot when the bag-holding rod is holding the bag. When the bag-packing robot is bagging, the bag-holding rod can return to its original position, thereby improving the packaging speed. Attached Figure Description

The advantages and features of this utility model will become clearer according to the following specific embodiments.

[0034] See Figure 1 and Figure 2 This embodiment describes a highly stable bag-holding rod for a material packaging sewing device. It mainly comprises two bag-holding rod bodies arranged opposite each other. The two bag-holding rod bodies move towards each other or away from each other to achieve bag holding or to return the bag-holding rods to their original position. The bag-holding rod body is a welded component, comprising a first connecting rod 1, a second connecting rod 2, a third connecting rod 3, and a connecting piece 4.

[0035] Specifically, the connector 4 has a U-shaped structure, including a first rectangular tube 41, a second rectangular tube 42, and a third rectangular tube 43; one end of the second rectangular tube 42 and the third rectangular tube 43 are respectively connected to both ends of the first rectangular tube 41, the second rectangular tube 42 and the third rectangular tube 43 are located on the same side of the first rectangular tube 41, the second rectangular tube 42 and the third rectangular tube 43 are arranged parallel to each other, and both are perpendicular to the first rectangular tube 41.

[0036] The sides of the upper support bag rod 01 and the lower support bag rod 02 that are close to and parallel to the first rectangular tube 41 are defined as the connecting surfaces. The other end of the second rectangular tube 42 is welded to the connecting surface of the upper support bag rod 01. The other end of the third rectangular tube 43 is welded with a fixing plate 44. The fixing plate 44 is connected to the connecting surface of the lower support bag rod 02 by at least two bolts.

[0037] The first connecting rod 1 and the third connecting rod 3 are both square tubes, while the second connecting rod 2 is a round tube. The lower end of the first connecting rod 1 is slidably and lockably connected to the bag-holding device 03 in the material packaging sewing equipment, thereby allowing the first connecting rod 1 to move up and down for positioning. Specifically, there are various locking methods. In this embodiment, it is preferable that multiple locking slots 5 are cut and provided on the side wall of the first connecting rod 1. The locking slots 5 are rectangular openings, and the multiple locking slots 5 are evenly distributed along the length direction of the first connecting rod 1, with a gap between adjacent locking slots 5. The specific number of locking slots 5 can be set according to the length of the first connecting rod 1, and the size of the gap can be set according to the height adjustment accuracy. In this embodiment, they are not specifically limited. By cooperating with the locking mechanism 04 in the bag-holding device 03 through the provided locking slots 5, the first connecting rod 1 is reliably locked.
