[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figure 1-5 A positioning structure for sealing woven bags includes a feeding plate 1, a vertical feeding mechanism 3 on one side below the feeding plate 1, and a spreading mechanism 4 on the upper side of the feeding plate 1 corresponding to the vertical feeding mechanism 3. The vertical feeding mechanism 3 is used to feed the woven bag to the side so as to deliver the woven bag to the sealing equipment for sealing, while the spreading mechanism 4 flattens the woven bag to ensure the sealing effect of the woven bag.

[0028] The vertical feeding mechanism 3 includes a feeding roller 31 rotatably mounted below the feeding plate 1 and a driving assembly for driving the feeding roller 31 to rotate. The axis of the feeding roller 31 is set along the material feeding direction, and a strip-shaped opening 2 is opened on the feeding plate 1 corresponding to the feeding roller 31. The driving assembly drives the feeding roller 31 to rotate, so as to move the woven bag in the direction perpendicular to the feeding direction, so as to send the woven bag into the sealing device on the side for sealing.

[0029] The spreading mechanism 4 includes two flattening components 5 symmetrically arranged along the axis of the feeding roller 31, a mounting frame 43 for mounting the flattening components 5, and a lifting component for driving the mounting frame 43 to rise and fall; the lifting component drives the flattening components 5 to rise and fall, so as to control the flattening components 5 to flatten the woven bag.

[0030] The flattening assembly 5 includes a connecting arm 51 tilted and rotatably mounted on a mounting frame 43, a spreading wheel 53 damped and rotatably mounted at the lower end of the connecting arm 51, and a spring 52 connecting the connecting arm 51 and the mounting frame 43. The two connecting arms 51 are tilted to both sides in a V-shape. When the flattening assembly 5 moves downward, the spreading wheel 53 contacts the woven bag and continues to rotate to both sides. With the damping design of the spreading wheel 53, it drives the opening of the woven bag to unfold and flatten to both sides, making it easier for the sealing equipment to seal the woven bag. When the flattening assembly 5 moves upward and resets, the spring 52 drives the connecting arm 51 to reset.

[0031] Based on the above technical solution, when the woven bag is sealed, the woven bag is fed onto the feeding plate 1, the drive assembly is started to drive the feeding roller 31 to rotate, so as to drive the woven bag to move vertically and move the woven bag to the flattening assembly 5. Then, the lifting assembly drives the flattening assembly 5 to move downward. The spreading wheel 53 releases the woven bag and drives the connecting arm 51 to rotate outward, so as to drive both sides of the woven bag to move outward, so as to flatten the part of the woven bag to be sealed, making it easier for the sealing equipment to flatten the woven bag.

[0032] In this technical solution, such as Figure 1-5 As shown, an inner toothed ring 532 is provided on the inner side of the spreading wheel 53. A rotating shaft 533 is rotatably connected to the inner side of the inner toothed ring 532. The rotating shaft 533 is fixedly connected to one side of the connecting arm 51. A sliding groove is provided on the annular sidewall of the rotating shaft 533, and a blocking tooth 534 matching the inner toothed ring 532 is slidably connected thereto. An elastic telescopic rod 535 is provided in the sliding groove to provide elastic force to the blocking tooth 534. The elastic telescopic rod 535 provides elastic force to the blocking tooth 534, pressing the blocking tooth 534 tightly onto the teeth of the inner toothed ring 532 to block the rotation of the spreading wheel 53. When the spreading wheel 53 receives greater resistance, it presses the blocking tooth 534 until the elastic telescopic rod 535 retracts, and the spreading wheel 53 continues to rotate, causing the woven bag to flatten to both sides at the sealing end.

[0033] In this technical solution, such as Figure 1-5 As shown, the outer side of the spreading wheel 53 is covered with an anti-slip mat and has anti-slip teeth 531. This ensures the flattening effect on the woven bag.

[0034] In this technical solution, such as Figure 1 and 2 As shown, the lifting assembly includes a cantilever plate 41 fixedly mounted above the feeding plate 1 and a lifting cylinder 42 vertically fixedly mounted on the cantilever plate 41. The telescopic end of the lifting cylinder 42 extends below the feeding plate 1 and is fixedly connected to the mounting frame 43. Multiple stabilizing rods 421 are vertically fixedly mounted on the mounting frame 43, passing through the cantilever plate 41 and slidably connected to it. The lifting cylinder 42 drives the mounting frame 43 to rise and fall, and the stabilizing rods 421 work together to ensure the stable vertical rise and fall of the mounting frame 43.

[0035] In this technical solution, as shown in Figures 1 and 2, multiple feeding rollers 31 and corresponding strip openings 2 are provided. Preferably, two are provided to ensure the vertical feeding effect on the woven bags.

[0036] In this technical solution, such as Figure 1 and 2As shown, the mounting frame 43 is equipped with multiple pressure rollers 431 corresponding one-to-one with the feeding rollers 31. Elastic mounting arms 432 connect the pressure rollers 431 to the mounting frame 43 on both sides. When the lifting assembly drives the mounting frame 43 downwards, the pressure rollers 431 first contact the woven bag and, in conjunction with the rotation of the feeding rollers 31, drive the woven bag to move vertically, ensuring stable and precise feeding of the woven bag. Through the design of the elastic mounting arms 432, after the woven bag is fed laterally, the lifting assembly drives the mounting frame 43 to continue downwards, and the elastic mounting arms 432 retract, not affecting the downward movement of the mounting frame 43, so as to drive the flattening assembly 5 downwards to flatten the woven bag.

[0037] In this technical solution, such as Figure 1 and 2 As shown, the drive assembly includes multiple feeding rollers 31 with one end coaxially connected to synchronous pulleys 32, a synchronous belt 33 sleeved on the outside of the multiple synchronous pulleys 32, and a servo motor 34 for driving one of the synchronous pulleys 32 to rotate. The servo motor 34, in conjunction with the synchronous belt 33, drives the multiple feeding rollers 31 to rotate synchronously, thereby ensuring stable lateral feeding of the woven bag.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
