Description

Technical Field

[0001] This utility model relates to the field of packaging bag manufacturing, specifically to a packaging bag production equipment. Background Technology

[0002] Packaging bags are widely used in our daily lives and work because of their convenience in use and carrying. Among various packaging bags, plastic bags are particularly widely used due to their unique sealing and lightweight properties. Plastic packaging bags include polyethylene plastic bags, polypropylene plastic bags, and polyvinyl chloride plastic bags. They can not only protect products and facilitate storage and transportation, but also promote sales and beautify products.

[0003] The existing production process for packaging bags is as follows: folding, hot pressing, and cutting. The folded raw material first enters the hot pressing station, where it is hot-pressed and sewn together. Since the raw material is continuously fed, the sewing process is continuous, resulting in a packaging bag with an opening on one side and closed on the other three sides. After sewing, the bag is cut into individual packaging bags at the cutting station, and finally, the packaging bags are output to the designated location via a feeding conveyor.

[0004] The folding process utilizes a folding device, which includes a power unit, a fabric placement shaft, and a folding mechanism. The fabric placement shaft is located at the bottom of the frame. The folding mechanism includes an isosceles triangular support with its base fixed to the top of the frame. The fabric winding and finishing device includes a first winding guide rail, a first winding roller, a second winding roller, a second winding guide rail, and a winding roller. The first winding guide rail is located directly below the vertex of the isosceles triangular support. The first winding roller is located on the frame below the first winding guide rail. The second winding roller and the second winding guide rail are parallel to the first winding roller. The fabric placement shaft and the fabric winding and finishing device are connected to the power unit via a transmission device.

[0005] The isosceles triangular support of the aforementioned folding device is fixed to the frame, meaning the position of the isosceles triangular support cannot be moved. Since the fabric is subjected to traction during the folding process, the magnitude of the traction force is generally constant. However, different fabrics will produce different deformations when subjected to the same traction force. If the deformation is too large, the fabric will not fit properly against the isosceles triangular support, and wrinkles will easily form when the fabric passes through the isosceles triangular support. After the fabric is folded, the wrinkles will still exist on the surface of the fabric, thus affecting the quality of the folded fabric. Utility Model Content

[0006] This invention provides a packaging bag production equipment that can eliminate wrinkles on raw materials.

[0007] The technical solutions to the above problems are as follows:

[0008] Packaging bag production equipment includes a first tensioning component, a first hot-pressing mechanism for sewing the longitudinal edges of the raw material, a second hot-pressing mechanism for sewing the transverse edges of the raw material, a first traction mechanism, a cutting mechanism, a first driving mechanism, and a second driving mechanism. The first hot-pressing mechanism is located downstream of the first tensioning component, the second hot-pressing mechanism is located downstream of the first hot-pressing mechanism, the first traction mechanism is located downstream of the second hot-pressing mechanism, and the cutting mechanism is located downstream of the first traction mechanism. The first driving mechanism is connected to the first hot-pressing mechanism, and the second driving mechanism is connected to the second hot-pressing mechanism, the first traction mechanism, and the cutting mechanism. The equipment also includes:

[0009] A second traction mechanism that applies traction force to the raw materials;

[0010] A reversing guide mechanism that changes the direction of travel of the raw materials output from the second traction mechanism is located downstream of the second traction mechanism;

[0011] A folding mechanism for folding raw materials, located downstream of a reversing guide mechanism;

[0012] The leveling mechanism is located downstream of the folding mechanism, which is located upstream of the first hot pressing mechanism.

[0013] When the raw material enters the second traction mechanism, the second traction mechanism generates a traction force on the raw material, causing the raw material on the take-up roller to be continuously output. After the raw material passes through the circumference of the first tension roller assembly and the first tension rod in sequence, the raw material passes through the first interval space. Then the raw material passes through the circumference of the second tension roller assembly and the third tension roller assembly in sequence. After the raw material passes through the second interval space, the raw material covers the two waists of the triangular plate. The triangular plate folds the raw material in half. Then the raw material passes through the first tensioning assembly, the leveling mechanism, and the first tensioning assembly. The paddle in the leveling mechanism is inserted into the folded raw material. The paddle generates a scraping force on the upper and lower layers of the raw material to eliminate wrinkles on the raw material. Then it passes through the first hot pressing mechanism, the second hot pressing mechanism, the edge cutting mechanism, the first traction mechanism, and the cutting mechanism in sequence.
