Description

Technical Field

[0001] This utility model relates to the field of woven bag packaging technology, and in particular to a woven bag packaging forming and pressing device. Background Technology

[0002] Currently, a utility model patent with announcement number CN219447409U discloses a woven bag packaging forming and pressing device. This patent uses a liftable pressure bar to squeeze stacked woven bags downwards, thereby compressing the loose woven bags and preventing them from being damaged during the packaging process.

[0003] However, after the flat straps are tied, the pressure fork on the pressure bar will also be tied inside. This technical solution uses a horizontal telescopic cylinder to push the horizontal moving beam, so that the pressure bar drives the pressure fork to be pulled away from the stack and eventually the pressure fork is separated from the stack. However, since the stacked woven bags have been compressed quite tightly in this process, and since the surface of some woven bags is relatively rough, the pressure fork may pull out part of the base surface of the woven bag during the movement.

[0020] The following will refer to the appendix in the embodiments of this utility model. Figure 1-3 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Example:

[0022] like Figures 1 to 3 As shown, this utility model discloses a woven bag packaging forming and pressing device, including a base 1, which is hollow inside. Two pressure rods 2 are arranged on the base 1, one on the left and one on the right. The lower ends of the pressure rods 2 are both located inside the base 1, and the upper ends of the pressure rods 2 extend upward and out of the base 1. At the same time, the base 1 is provided with a lifting mechanism for driving the two pressure rods 2 to move up and down together, and a displacement mechanism for driving the two pressure rods 2 to move closer or further apart. Correspondingly, the upper end surface of the base 1 is provided with a movable groove 11 for the pressure rods 2 to move. Each pressure rod 2 is equipped with a mounting seat 33. In this structure, the pressure rod 2 is rotatably mounted on the mounting seat 33, and the mounting seat 33 is located inside the base 1. At the same time, the mounting seat 33 is provided with a rotating mechanism for controlling the rotation angle of the pressure rod 2. In addition, a support plate 12 is fixedly mounted on the base 1. The support plate 12 is located between the two pressure rods 2, and a tray 13 is rotatably mounted on the support plate 12.

[0023] Furthermore, a lifting plate 31 is provided inside the base 1, and the lifting mechanism includes a lifting cylinder 32, which is fixedly installed inside the base 1. The piston rod of the lifting cylinder 32 extends upward and is fixedly connected to the lower end of the lifting plate 31.

[0024] In this structure, the mounting bases 33 are all slidably disposed on the upper end of the lifting plate 31. Meanwhile, the displacement mechanism specifically includes a lead screw 35 and a first motor 34. The first motor 34 is fixedly disposed on the lifting plate 31, the lead screw 35 is rotatably disposed on the lifting plate 31 and connected to the output end of the first motor 34, and the mounting base 33 is sleeved on the lead screw 35 and connected to the lead screw 35 through threaded engagement. In addition, the lead screw 35 is a bidirectional lead screw 35.

[0025] Furthermore, the rotating mechanism specifically includes a second motor 41, a first synchronous pulley 42, a second synchronous pulley 43, a synchronous belt 44, a first gear 45, and a second gear 46. In this structure, the first gear 45, the second gear 46, and the second synchronous pulley 43 are rotatably connected to the mounting base 33. The pressure rod 2 is fixedly mounted on the first gear 45, the second gear 46 is coaxially fixedly connected to the second synchronous pulley 43, and the first synchronous pulley 42 is located between the two mounting bases 33 and rotatably mounted on the lifting plate 31. Correspondingly, the second motor 41 is fixedly mounted on the lifting plate 31 and its output end is connected to the first synchronous pulley 42. Finally, the second synchronous pulley 43 and the first synchronous pulley 42 are both fitted with a synchronous belt 44. At the same time, the lifting plate 31 is also provided with a synchronous belt tensioning mechanism.

[0026] The timing belt tensioning mechanism specifically includes a side plate 51, a push block 52, and an elastic abutment 53. Two push blocks 52 are provided and located on either side of the first timing pulley 42. In this structure, both push blocks 52 are located between the first timing pulley 42 and the second timing pulley 43 and are used to abut against the outer surface of the timing belt 44. Meanwhile, the side plate 51 is fixedly mounted on the lifting plate 31. In this structure, a sliding rod 54 is fixedly connected to each push block 52. The end of the sliding rod 54 away from the push block 52 is slidably mounted on the lifting plate 31. The elastic abutment 53 abuts against the lifting plate 31 and the push block 52, thereby pushing the push block 52 towards the timing belt 44. Furthermore, limit plates 55 are provided at both the upper and lower ends of the push block 52. These limit plates 55 are mainly used to limit the timing belt 44.

[0027] The working principle of the above structure is as follows: the lifting cylinder 32 is used to move the lifting plate 31 up and down, thereby raising and lowering the pressing fork 21 on the pressing rod 2. The pressing fork 21 is the same as in the prior art and is mainly used to compress woven bags into stacks. The first motor 34 can be used to adjust the distance between the two pressing rods 2, so that the structure can press woven bags of different lengths and widths. In addition, since the pressing rod 2 can rotate in this structure, the second motor 41 can be started. Utilizing the synchronous rotation relationship between the first synchronous wheel 42 and the second synchronous wheel 43, as well as the meshing transmission relationship between the first gear 45 and the second gear 46, the pressing fork 21 on the pressing rod 2 can swing to a specific angle. The advantage of this is that the pressing fork 21 can be staggered from the flat strap, avoiding the situation where the flat strap ties the pressing fork 21 and the woven bag together. This setting allows the binding of the woven bag by the flat strap and the pressing of the woven bag by the pressing fork 21 to coexist without interfering with each other. After the woven bag is bundled, the pressing fork 21 can be moved directly to remove the pressing fork 21 from the woven bag.
