Description

Technical Field

[0001] This utility model relates to the field of woven bag processing technology, and in particular to a folding device for producing plastic woven bags. Background Technology

[0002] Plastic woven bags are a type of bag that can hold items very well. Chinese utility model patent, authorized announcement number "CN221641952U", discloses a folding device for producing plastic woven bags. The folding device for producing plastic woven bags in this utility model uses a push plate to make the ball bearings on one side of the contact plate contact and limit the woven bag opening, thereby realizing alternative support for the woven bag opening. During the bag feeding process, close contact between human hands and the conveying equipment is avoided, ensuring the safety of the feeding process.

[0003] Although the above technical solution has rolling balls on the contact plate to facilitate rolling, the woven bag material is relatively soft, and the connecting plate clamps the woven bag under the action of two springs. This makes it easy for the folded bag opening to be misaligned with the bag body during the conveying process, which may cause the woven bag to shift during subsequent folding. Therefore, we propose a folding device for the production of plastic woven bags. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a folding device for the production of plastic woven bags. This device can solve the problem that although the contact plate is equipped with rolling balls for easy rolling, the woven bag material is relatively soft, and the connecting plate will clamp the woven bag under the action of two springs. This causes the folded bag opening to be misaligned with the bag body during the conveying process, which may lead to the woven bag shifting during subsequent folding.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a folding device for producing plastic woven bags, comprising:

[0026] Please see Figure 1-4 This utility model provides a technical solution: a folding device for producing plastic woven bags, comprising:

[0027] Conveyor table 1, on which a folding assembly is provided;

[0028] The bag opening guide structure is located on the hem folding assembly;

[0029] The bag opening guide structure includes a fixed guide plate 7, two pull rods 13, two springs 14, a pull plate 12, and a movable guide plate 10. The fixed guide plate 7 is fixedly installed on the folding assembly. The two pull rods 13 are slidably connected to the fixed guide plate 7. The pull plate 12 is fixedly connected to one end of the two pull rods 13. The two springs 14 are sleeved on the outer surface of the corresponding pull rods 13. One end of each spring 14 is fixedly connected to the fixed guide plate 7. The ends of each spring 14 away from the fixed guide plate 7 are fixedly connected to the corresponding pull rods 13. The ends of each pull rod 13 away from the pull plate 12 slide through the fixed guide plate 7 and are fixedly connected to the movable guide plate 10. Multiple rotating rollers 11 are rotatably connected inside the movable guide plate 10. A rotating groove 16 is opened on the side of the fixed guide plate 7 near the movable guide plate 10.

[0030] The bag opening guide structure also includes multiple drive rollers 15, multiple rotating rods 17, multiple synchronous belts 18, multiple synchronous pulleys 19, and a drive motor 9. The multiple rotating rods 17 are rotatably connected inside the rotating groove 16. The multiple drive rollers 15 and multiple synchronous pulleys 19 are fixedly sleeved on the outer surface of the corresponding rotating rods 17. The multiple synchronous belts 18 are drivenly sleeved on the outer surface of the corresponding two synchronous pulleys 19. The drive motor 9 is fixedly installed at the bottom of the fixed guide plate 7. The output end of the drive motor 9 rotatably extends into the interior of the rotating groove 16 and is fixedly connected to the corresponding rotating rod 17.

[0031] The folding assembly includes two fixed base plates 2, two connecting plates 4, and two mounting brackets 5. The two fixed base plates 2 are fixedly connected to both sides of the conveyor table 1. Two electric telescopic rods 3 are fixedly installed on the top of each of the two fixed base plates 2. The telescopic ends of the four electric telescopic rods 3 are fixedly connected to the corresponding connecting plates 4. The two mounting brackets 5 are fixedly installed on one side of the corresponding connecting plates 4. The fixed guide plate 7 is fixedly connected to the corresponding mounting bracket 5.

[0032] The top of each of the two mounting brackets 5 is fixedly connected to a limiting plate 8, and the top of the two limiting plates 8 is fixedly installed with a folded edge plate 20. The top of the conveyor table 1 is fixedly connected to two protective plates 6.

[0033] Furthermore, when using the device, the plastic woven bag is placed on the conveyor table 1. The conveyor table 1 runs continuously to transport the woven bag towards the folding assembly. The two protective plates 6 fixedly connected to the top of the conveyor table 1 play a certain protective and guiding role, preventing the woven bag from deviating during the transport process and ensuring that the woven bag can enter the subsequent folding area more accurately. The user presses the pull plate 12, which drives the two pull rods 13 to move and simultaneously moves the moving guide plate 10 away from the fixed guide plate 7. The spring 14 is compressed, and then the opening of the woven bag is placed between the moving guide plate 10 and the fixed guide plate 7.

[0034] Then, the drive motor 9 starts, and the drive motor 9 drives the rotating rod 17 connected to it to rotate. The synchronous wheel 19 on the rotating rod 17 drives other synchronous wheels 19 to rotate through the synchronous belt 18, thereby causing all the rotating rods 17 and drive rollers 15 to rotate. The drive rollers 15 contact the opening of the woven bag and convey the opening of the bag forward through friction, ensuring that the opening of the bag can enter the folding area smoothly and continuously. The multiple rotating rollers 11 rotatably connected inside the moving guide plate 10 can reduce the friction between the rollers and the opening of the bag, making the conveying of the opening of the bag smoother.

[0035] Four electric telescopic rods 3 start synchronously, pushing two connecting plates 4 to move. The connecting plates 4 drive the mounting frame 5, the limiting plate 8, and the folding plate 20 to adjust their height. When the opening of the woven bag is guided to the appropriate position, the limiting plate 8 can restrict the position of the woven bag to prevent it from shifting during the folding process, thus ensuring the quality and accuracy of the folding. Then, the folding plate 20 folds the opening of the bag downwards to complete the folding operation.

[0036] The distance between the movable guide plate 10 and the fixed guide plate 7 can be flexibly adjusted, making it easy to place the woven bag opening between the two guide plates. The drive roller 15 contacts the woven bag opening and uses friction to smoothly and continuously convey the bag opening forward. At the same time, the multiple rotating rollers 11 rotatably connected inside the movable guide plate 10 further reduce the friction between the rollers and the bag opening, effectively preventing problems such as wrinkles and jamming of the bag opening due to excessive friction during the conveying process, ensuring the smoothness of the bag opening conveying and improving the accuracy of the folding step.
