Description

Technical Field

[0001] This utility model relates to the technical field of container bag processing equipment, specifically a container bag fabric roll and folding device. Background Technology

[0002] Flexible Intermediate Bulk Containers (FIBCs) are made from polyester fibers such as polypropylene and polyethylene, sewn together by a sewing machine. They are widely used for packaging various powdery, granular, and lumpy goods, including chemicals, building materials, plastics, minerals, grains, and cement. Before sewing, the bag fabric needs to be folded and sewn to ensure the bag's strength. However, current technology lacks automation in the folding process, relying solely on manual operation. This not only affects the quality and efficiency of the folding but also significantly increases the labor intensity, thus limiting its applicability and practicality. Utility Model Content

[0003] To address the shortcomings of existing technologies, a container bag fabric roll-folding device is disclosed, which includes a conveyor belt, and a symmetrical bearing plate is provided at the upper end of the conveyor belt. The bearing plate is installed on the conveyor belt by support columns. The support plate on the right is provided with a folded edge structure, which includes a first electric push rod installed on the support plate, and a top plate is installed on the first electric push rod; A second electric push rod is mounted on the bearing plate on the left side, and a push plate is mounted on the second electric push rod; An arched channel is installed on the support plate, and the arched channel gradually narrows from left to right.

[0004] Preferably, an auxiliary structure is installed on one side of the arched channel. The auxiliary structure includes a third electric push rod that is inclinedly disposed in the arched channel. A sleeve is installed on the third electric push rod. A slide rod is slidably disposed inside the sleeve. A ball bearing is rolled at the top of the slide rod. The slide rod and the sleeve are connected by a spring.

[0005] Preferably, an auxiliary conveyor belt is installed between the pair of said bearing plates.

[0006] Preferably, the inner wall of the sleeve is provided with a sliding groove, and a slider is provided in the sliding groove, the slider being fixed on the sliding rod.

[0007] Preferably, the tilt angle of the plurality of third electric push rods gradually increases from left to right.

[0008] Preferably, the bearing plate and the support column are connected by a reinforcing rod.

[0009] This utility model has the following beneficial effects: The utility model has a reasonable structure and novel design. In use, the material is placed on a conveyor belt, and the worker guides the upper end of the material between a pair of auxiliary conveyor belts. The material is transported with the conveyor belt. When it reaches the folding structure, the first electric push rod is activated, driving the top plate to move and press against the upper side of the material. The second electric push rod is activated, driving the push plate to move, causing the push plate to push the upper end of the material to bend. The bent material enters the arched channel, with the upper end of the material adhering to the inner wall of the arched channel in a curved shape. As the channel gradually narrows, the gap between the bent materials gradually decreases, facilitating subsequent sewing. By activating the third electric push rod, the sleeve is moved, thereby moving the ball bearings. The ball bearings allow the material to better adhere to the inner wall of the arched channel, and the springs ensure that the ball bearings remain attached to the inner wall of the arched channel.

Detailed Implementation

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figure 1-3 A container bag fabric roll-folding device includes a conveyor belt 1 for transporting materials. The upper end of the conveyor belt 1 is provided with symmetrical bearing plates 2, which are mounted on the conveyor belt 1 by support columns. A folded edge structure is provided on the right-side support plate 2. The folded edge structure includes a first electric push rod 3 installed on the support plate 2, and a top plate 4 is installed on the first electric push rod 3. A second electric push rod 5 is installed on the left bearing plate 2, and a push plate 6 is installed on the second electric push rod 5; The material is transported along the conveyor belt 1. When it reaches the folding structure, the first electric push rod 3 is activated, which drives the top plate 4 to move so that the top plate 4 abuts against the upper side of the material. The second electric push rod 5 is activated, which drives the push plate 6 to move so that the push plate 6 pushes the upper end of the material to bend. An arched channel 7 is installed on the support plate 2. The arched channel 7 gradually narrows from left to right, and a sewing machine is installed at the exit of the arched channel 7. The bent material enters the arched channel 7, with the upper end of the material adhering to the inner wall of the arched channel 7 in a bent shape. As the channel gradually narrows, the gap between the bent material gradually decreases, making it easier to sew later. An auxiliary structure is installed on one side of the arched channel 7. The auxiliary structure includes a third electric push rod 8 that is inclinedly set in the arched channel 7. A sleeve 9 is installed on the third electric push rod 8. A slide rod 10 is slidably set in the sleeve 9. A ball bearing 11 is rolled at the top of the slide rod 10. The ball bearing 11 can rotate 360°. The slide rod 10 and the sleeve 9 are connected by a spring. By activating the third electric push rod 8, the sleeve 9 is moved, which in turn moves the ball bearing 11. The ball bearing 11 allows the material to better adhere to the inner wall of the arched channel 7. The springs provided can keep the ball bearing 11 attached to the inner wall of the arched channel 7. An auxiliary conveyor belt 12 is installed between a pair of support plates 2. The material is clamped by the pair of auxiliary conveyor belts 12, which makes it easy to fold the upper end of the material. A groove 13 is provided on the inner wall of the sleeve 9, and a slider 14 is provided in the groove 13. The slider 14 is fixed on the slide rod 10 to prevent the slide rod 10 from moving out of the sleeve 9. The tilt angle of the multiple third electric actuators 8 gradually increases from left to right; The load-bearing plate 2 is connected to the support column by a reinforcing rod 15, which strengthens the connection between the load-bearing plate 2 and the support column.

[0014] Example: In use, the material is placed on the conveyor belt 1. The worker guides the upper end of the material between a pair of auxiliary conveyor belts 12. The material is transported with the conveyor belt 1. When it reaches the folding structure, the first electric push rod 3 is activated, which moves the top plate 4 so that the top plate 4 abuts against the upper side of the material. The second electric push rod 5 is activated, which moves the push plate 6 so that the push plate 6 pushes the upper end of the material to bend. The bent material enters the arched channel 7. The upper end of the material is bent against the inner wall of the arched channel 7. As the channel gradually narrows, the gap between the bent materials gradually decreases, which facilitates subsequent sewing. The third electric push rod 8 is activated, which moves the sleeve 9, thereby moving the ball bearing 11. The ball bearing 11 allows the material to better fit against the inner wall of the arched channel 7. The springs can keep the ball bearing 11 in contact with the inner wall of the arched channel 7.
