[0002] Woven bags, commonly known as snakeskin bags, are a type of plastic bag, mainly used for packaging, such as chemical raw materials, food, engineering materials and other products that need packaging and protection. When using a woven bag, it usually requires two people to use it. Generally, one person is required to hold the bag mouth open, and the other person fills the bag with items. For ease of use, a mouth opener is generally used to open the bag mouth. Existing mouth openers generally use a hook to hang the woven bag to open it or clamp the upper end of the woven bag to open the bag mouth. However, using a hook to hang the woven bag will damage the woven bag, and clamping the upper end of the woven bag will cause the woven bag to be unable to be filled with items.

These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0023] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0024] Reference Figures 1 to 5 As shown, the utility model describes a plastic woven bag opening device, including an opening device body consisting of three transverse circles 1 and three longitudinal beams 2, a handle 17 is provided on the upper transverse circle 1, and three follower blocks 5 are equidistantly provided on the side wall of the upper transverse circle 1, and the follower blocks 5 are movably arranged in the transverse circle 1. The follower blocks 5 are driven by a driving mechanism to place the opening device body in the woven bag, and the woven bag is opened from the inside, thereby avoiding the damage of the woven bag by the hook-type opening and avoiding the problem of the woven bag not being able to be filled due to the clamping edge opening.

[0025] The driving mechanism includes an inner ring 3 rotatably arranged in the horizontal ring 1 and a through groove 18 opened on the side wall of the horizontal ring 1. A driving rod 19 for driving the inner ring 3 to rotate is provided in the through groove 18. A driving block 4 for driving the driven block 5 to move is provided at a position corresponding to the inner ring 3 and the driven block 5. A fixing mechanism for fixing the position of the inner ring 3 is provided in the horizontal ring 1. By pulling the driving rod 19, the inner ring 3 can be driven to rotate through the driving rod 19, thereby driving the driving block 4 to rotate. The driven block 5 can be driven to move through the driving block 4, so that the driven block 5 can be extended from the horizontal ring 1, thereby supporting the woven bag.

[0026] A fixing plate 7 is disposed on the side wall of the driven block 5 , and a driven block reset spring 8 is disposed between the fixing plate 7 and the horizontal circle 1 , so that the driven block 5 can be reset after use by the driven block reset spring 8 .

[0027] The fixing mechanism includes a limiting tooth mounting plate 9 arranged on the inner ring 3, a limiting tooth 10 is arranged on the limiting tooth mounting plate 9, a movable tooth mounting plate 11 is arranged at a position corresponding to the limiting tooth mounting plate 9 in the inner ring 3, and a movable tooth 12 meshing with the limiting tooth 10 is arranged on the movable tooth mounting plate 11. After the driven block 5 is extended, the engagement between the limiting tooth 10 and the movable tooth 12 can be used to fix the position of the inner ring 3, thereby fixing the position of the driven block 5, thereby ensuring the stability of the support mouth. After use, the movable tooth mounting plate 11 is pulled to disengage the limiting tooth 10 from the movable tooth 12, thereby facilitating the retraction of the driven block 5.

[0028] The movable tooth mounting plate 11 is driven by a pull rod 15 movably arranged on the horizontal circle 1. A movable tooth mounting plate reset spring 13 is arranged between the movable tooth mounting plate 11 and the horizontal circle 1. A guide rod 14 is arranged on the side wall of the movable tooth mounting plate 11. The end of the guide rod 14 is slidably connected to the horizontal circle 1. The movable tooth mounting plate reset spring 13 can be used to facilitate the reset of the movable tooth mounting plate 11, and the guide rod 14 can be used to guide the movement direction of the movable tooth mounting plate 11.

[0029] A limit plate 16 is provided at a position corresponding to the driving block 4 in the transverse circle 1 , and the limit plate 16 can be used to limit the rotation angle of the driving block 4 , thereby preventing the driving block 4 from being out of contact with the driven block 5 .

[0030] The ends of the driven blocks 5 are provided with rollers 6, and the provision of the rollers 6 can prevent the woven bag from being damaged when the mouth-opening device body is taken out.
