[0014] Furthermore, the first and third connecting rods are both square tubes, while the second connecting rod is a round tube.

[0015] 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;

[0016] The locking port is used to cooperate with the locking mechanism in the bag-holding device to lock the first connecting rod.

[0017] Furthermore, the locking opening is a rectangular opening.

[0018] Meanwhile, this utility model also provides a bag-holding device for a material packaging sewing equipment, including two bag-holding mechanisms and the aforementioned bag-holding rod for a material packaging sewing equipment;

[0019] Both of the bag-holding mechanisms include a connecting sleeve and a locking mechanism mounted on the connecting sleeve;

[0020] The upper end of the connecting sleeve is provided with a connecting hole that is adapted to the first connecting rod;

[0021] The lower end of the first connecting rod can be slidably connected to the connecting hole;

[0022] Both of the two bag-holding mechanisms have openings on opposite sides of the connecting sleeves. The output end of the locking mechanism contacts the first connecting rod through these openings to lock the first connecting rod.

[0023] Furthermore, each of the two bag-holding mechanisms has at least one opening on one side of the connecting sleeves that are close to each other. A flexible pad is provided at the opening of the connecting sleeve, and the flexible pad is used to provide flexible support for the first connecting rod when it is locked by the locking mechanism.

[0024] Furthermore, there are two openings, located at the upper end and middle of the connecting sleeve, respectively;

[0048] To make the objectives, advantages, and features of this utility model clearer, the following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a bag-holding rod and bag-holding device for a material packaging sewing equipment. The advantages and features of this utility model will become clearer according to the following specific embodiments.

[0049] See Figure 1 and Figure 2This embodiment describes a bag-holding rod for a material packaging sewing device, mainly comprising 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 U-shaped plate 4 formed by sequentially connecting an upper horizontal plate 41, a vertical plate 42, and a lower horizontal plate 43.

[0050] Specifically, the U-shaped plate 4 is a bent sheet metal part, and its upper horizontal plate 41, vertical plate 42 and lower horizontal plate 43 are all bent by external tools.

[0051] Among them, the first connecting rod 1 and the third connecting rod 3 are both square tubes, and the second connecting rod 2 is a round tube.

[0052] The lower end of the first connecting rod 1 is slidably and lockably connected to the bag-holding device in the material packaging sewing equipment, thereby enabling 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 8 in the bag-holding device through the provided locking slots 5, the first connecting rod 1 is reliably locked.

[0053] The upper end of the first connecting rod 1 is welded to one end of the second connecting rod 2; the lower end of the third connecting rod 3 is welded to the other end of the second connecting rod 2, and the upper end is welded to the back of the vertical plate 42 of the U-shaped plate 4; the upper horizontal plate 41 and the lower horizontal plate 43 of the U-shaped plate 4 are respectively connected to the upper bag support rod 01 and the lower bag support rod 02 in the material packaging sewing equipment through threaded rods.

[0054] The length direction of the second connecting rod 2 is set at an angle to the length directions of the first connecting rod 1 and the third connecting rod 3, respectively. The third connecting rod 3 is located on the side of the first connecting rod 1 away from the bag clamp in the material packaging sewing equipment, thereby achieving an eccentric setting of the bag-holding rods. The first connecting rod 1 is set vertically in the initial state, and the second connecting rod 2 is set horizontally in the initial state. The third connecting rods 3 in the two bag-holding rod bodies are set at an inclination towards each other, and the distance between the upper ends of the third connecting rods 3 in the two bag-holding rod bodies is smaller than the distance between the lower ends.

[0055] See Figures 2 to 4This embodiment provides a bag-holding device for a material packaging sewing machine, comprising two bag-holding mechanisms 6 and a bag-holding rod as described above. Each bag-holding mechanism 6 includes a connecting sleeve 7 and a locking mechanism 8 mounted on the connecting sleeve 7.

[0056] A connecting hole, i.e. a square-shaped hole, is provided at the upper end of the connecting sleeve 7 to match the first connecting rod 1, so that the lower end of the first connecting rod 1 can be slidably connected in the connecting hole; in the two bag-holding mechanisms 6, the connecting sleeve 7 is provided with an opening on the side away from each other, and the output end of the locking mechanism 8 contacts the first connecting rod 1 through the opening to lock the first connecting rod 1.

[0057] Each of the two bag-holding mechanisms 6 has at least one opening on one side of the connecting sleeve 7. In this embodiment, considering the length of the connecting sleeve 7 and the issue of support stability, the number of openings is set to two, and the two openings are located near the upper end and the middle of the connecting sleeve 7, respectively. A flexible pad 9 is installed on the connecting sleeve 7 at the opening through the pressure plate 10. The flexible pad 9 is specifically a rubber pad. The rubber pad provides flexible support to the first connecting rod 1 when it is locked by the locking mechanism 8, and at the same time increases the friction and improves the stability of the first connecting rod 1 when locked.

[0058] The locking mechanism 8 includes two connecting plates 81, two locking levers 82, and a positioning lever 84. The two connecting plates 81 are respectively disposed on two opposite side walls of the connecting sleeve 7 located on the side wall where the opening is located, and can provide installation positions for the locking levers 82 and the positioning lever 84.

[0059] Two locking wrenches 82 are respectively disposed at both ends of the connecting plate 81 along its length. Each locking wrench 82 includes a locking block 821 and a locking handle 822. The two ends of the locking block 821 are respectively set as arc-shaped, with one end being the larger end and eccentrically set, and the other end being the smaller end. One end of the locking handle 822 is rotatably mounted on the two connecting plates 81 via a pin 83 to the larger end of the locking block 821. The smaller end of the locking block 821 is connected to the locking handle 822 via a mounting shaft. Thus, after the locking block 821 rotates a certain angle, the larger end of the locking block 821 can contact the first connecting rod 1 through the opening, thereby achieving the pressing and locking of the first connecting rod 1.

[0060] A notch is provided in the middle of the two connecting plates 81, that is, between the two pins 83. A mounting plate 85 is provided at the upper end of the notch. A threaded hole is provided at each end of the mounting plate 85. The positioning paddle 84 is fixedly installed on the mounting plate 85 by bolts. The side wall of the first connecting rod 1 is provided with multiple locking holes 5, which are evenly distributed along the length of the first connecting rod 1. Furthermore, a locking block 821 that matches the locking hole 5 is provided on the inner side of the lower end of the positioning paddle 84. The positioning paddle 84 can elastically deform, so that the locking block 821 can be inserted into the locking hole 5 on the first connecting rod 1 through the opening, thereby locking the first connecting rod 1.

[0061] When locked, one side of the first connecting rod 1 contacts the rubber pad, and the other side is pressed by the arc surface of the locking block 821, while it is fixed by the positioning paddle 84, so that it can be stably connected and fixed to the connecting sleeve 7.
