Description

Technical Field

[0001] This utility model relates to the technical field of tote bag production equipment, specifically an automated production line for paper tote bags. Background Technology

[0002] Tote bags are a common type of daily necessity, and they come in a variety of materials, with paper tote bags being an important branch.

[0003] Early paper tote bag production involved manual folding and pasting, resulting in significant deficiencies in both production efficiency and quality. Now, complete equipment is available for paper tote bag production, achieving fully automated production from material input to final product output.

[0004] In current automated paper bag production equipment, the folding of the entire sheet of paper is generally accomplished by the equipment conveying the paper along a specific trajectory. This is essentially folding the paper directly, which can easily lead to the paper not bending in the preset position, resulting in unwanted wrinkles and affecting the final product quality. Some equipment performs creasing on the paper before folding, but the creasing structure is poorly designed and does not effectively promote subsequent folding. Summary of the Invention

[0005] This utility model is an automatic production line for paper tote bags. It adds a creasing mechanism to the traditional production line. The creasing mechanism adopts a two-way structure and creasing the paper according to the folding direction of the folding line of the paper bag being produced. This provides better guidance for the subsequent folding operation, making the folding operation smoother and thus improving the overall production quality of the product.

[0006] The present invention adopts the following technical solution:

[0007] An automatic production line for paper tote bags includes a frame and a feeding section, a folding and forming section, a cutting section, and a collecting section mounted on the frame. The folding and forming section includes a folding edge section and a folding bottom section. A creasing mechanism is also provided in front of the folding edge section, and the creasing mechanism creasing the paper from the top and bottom respectively.

[0008] Furthermore, the creasing mechanism includes a creasing plate and a support plate. The creasing plate is mounted on the frame via a drive shaft, and the support plate is provided at a position corresponding to the creasing plate. The paper passes through the creasing plate and the support plate to achieve the creasing operation.

[0009] Furthermore, the indentation mechanism is provided in two corresponding sets, with the indentation disks corresponding to the two sets of indentation mechanisms located on the same horizontal line, and the corresponding support plates respectively located at the top and bottom of the indentation disk.

[0010] Furthermore, the support plate extends to the top or bottom of the adjacent indentation plate. The front and rear parts of the extended section of the support plate are respectively provided with hinge seats. The support plate is hinged to the corresponding drive shaft of the adjacent indentation plate through the hinge seats. The front and rear parts of the two support plates are connected by tension springs. The tension springs cause the support plates to move closer to the center.

[0011] Furthermore, the support plate is provided with a driven roller shaft, which is hinged to the support plate, and the driven roller shaft and the indentation plate are vertically corresponding to each other.

[0012] Furthermore, the indentation disk has a circular disk structure, and an annular strip-shaped protrusion is provided at the center of the outer edge of the indentation disk.

[0013] Furthermore, the creasing disc is slidably mounted on the drive shaft, and a sliding sleeve corresponding to the drive shaft is provided at the center of the creasing disc. The creasing disc slides on the drive shaft through the sliding sleeve. The creasing disc is provided with a number of corresponding creasing discs according to the bending of the paper. A tightening screw is provided on the sliding sleeve. The tightening screw rotates and extends on the sliding sleeve to tighten and release the drive shaft.

[0014] The present invention, by adopting the above-described technical solution, has the following beneficial effects:

[0015] The paper tote bag production line corresponding to this device is equipped with a creasing mechanism, and the creasing mechanism adopts an up-and-down corresponding method. In actual use, the position of the creasing plate is set according to the folding of the paper bag, so that the creasing corresponds to the upward and downward bending of the paper, making it less likely for folding errors to occur in the subsequent folding and forming process.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments. The following embodiments are only one expression of the present invention and are not a complete limitation on the technical solutions described in this application.

[0020] like Figures 1-3The diagram shows an automatic production line for paper tote bags, which includes a frame 1 and a feeding section 2, a folding and forming section 3, a cutting section 4, and a collecting section 5 mounted on the frame 1.

The creasing disk 601 is mounted on the frame 1 via a drive shaft 603, and the support plate 602 is provided at a position corresponding to the creasing disk 601. The paper passes through the creasing disk 601 and the support plate 602 to achieve the creasing operation.

[0022] Furthermore, the indentation mechanism 6 is provided with two corresponding sets, and the indentation disks 601 corresponding to the two sets of indentation mechanisms 6 are located on the same horizontal line, and the corresponding support plates 602 are respectively provided on the top and bottom of the indentation disks 601.

[0023] Furthermore, the support plate 602 extends to the top or bottom of the adjacent indentation disk 601. The front and rear parts of the extended section of the support plate 602 are respectively provided with hinge seats 604. The support plate 602 is hinged to the drive shaft 603 corresponding to the adjacent indentation disk 601 through the hinge seats 604. The front and rear parts of the two support plates 602 are connected by tension springs 605 respectively. The tension springs 605 cause the support plates 602 to move closer to the center.

[0024] Furthermore, the support plate 602 is provided with a driven roller shaft 606, which is hinged to the support plate 602, and the driven roller shaft 606 and the indentation plate 601 are vertically corresponding to each other.

[0025] Furthermore, the indentation disk 601 has a circular disk structure, and an annular strip-shaped protrusion 607 is provided at the center of the outer edge of the indentation disk 601.

[0026] Furthermore, the indentation disk 601 is slidably mounted on the drive shaft 603. A sliding sleeve 608 corresponding to the drive shaft 603 is provided at the center of the indentation disk 601, and the indentation disk 601 slides on the drive shaft 603 through the sliding sleeve 608. The indentation disk 601 is provided with a number of corresponding indentations according to the bending of the paper. A tightening screw 609 is provided on the sliding sleeve 608, and the tightening screw 609 rotates and extends on the sliding sleeve 608 to tighten and release the drive shaft 603.

[0027] The creasing mechanism in the production line corresponding to this device is equipped with two sets of creasing discs, which perform creasing operations from the top and bottom of the paper respectively. When it comes to paper, you can choose to use the creasing discs to creasing from the bottom at the position where the paper is bent upwards, and use the creasing discs to creasing from the top at the position where the paper is bent downwards, to press out indentations on the corresponding side of the paper, which facilitates subsequent folding operations.

[0028] The indentation produced by the indentation plate of this device is a single-sided concave structure, which, compared to the double-sided concave indentation design, increases the limitation on the folding direction and is more advantageous for subsequent folding operations.
