Description

Technical Field

[0001] This utility model relates to the technical field of paper towel folding, specifically to a paper towel folding device for disposable tableware. Background Technology

[0002] Currently, due to the development of the fast food and takeout industries, tableware is often packaged together in the same bag for convenience. Examples include napkins, straws, knives, forks, and spoons. Napkins typically need to be folded before packaging, hence the development of paper folding equipment. This equipment is primarily used for folding paper of various sizes and thicknesses within a design scope. Since manual folding methods are far from meeting the needs of modern production, paper folding equipment can significantly improve efficiency, reduce manpower, lower labor costs, and reduce scrap rates and energy consumption, thereby reducing production costs. The high precision and stability of automated paper folding equipment ensure product quality, reduce defect rates and low yields, and improve product craftsmanship and quality standards.

[0003] The automated paper folding device disclosed in patent application number 202411429625.X includes a feeding mechanism for conveying paper, a folding mechanism on one side of the feeding mechanism, a first folding support plane on the surface of the folding mechanism for supporting the paper, creases on the paper at the two edges of the first folding support plane, the area of ​​the first folding support plane being adjusted by an adjustment mechanism inside the folding mechanism, a first pressing mechanism on one side of the folding mechanism, a first conveying mechanism on one side of the first pressing mechanism, a second pressing mechanism on one side of the first conveying mechanism, and a second conveying mechanism on one side of the second pressing mechanism. The first pressing mechanism, the first conveying mechanism, and the second pressing mechanism are driven by a drive mechanism. This structure is implemented mechanically, is not prone to failure, and has high controllability, enabling the entire device to fold paper of different widths, increasing the versatility of the device. However, this structure still has the following problems in use:

[0004] After the paper is folded, it slides along the cutter drive plate, which drives the metal longitudinal cutter downwards to cut the compacted and folded tissue paper. After being cut, the paper falls onto the surface of the second conveying mechanism after passing through the gap between the second and third pressure rollers on the lower right side. The paper is only conveyed to the second conveying mechanism by the rotational force of the second and third pressure rollers on the lower right side. This structure requires that the gap between the second and third pressure rollers on the lower right side be tight enough. After long-term use, the gap between the pressure rollers is prone to loosening. Once loosened, the paper will not easily exit between the second and third pressure rollers on the lower right side, but will be directly conveyed by the cutter drive plate into the gap between the left and right pressure rollers below, and will not accurately reach the surface of the second conveying mechanism. Therefore, it is particularly important to ensure that the folded paper is accurately conveyed between the second and third pressure rollers on the lower right side. Utility Model Content

A horizontal pusher assembly is provided below one of the second pressing rollers. The horizontal pusher assembly is used to accurately push the paper between the second pressing roller and the first pressing roller into the space between the two first pressing rollers. The horizontal pusher assembly includes a metal transverse pusher, a pusher drive plate, a pusher drive arm, and a motor. The motor is located on the back of the frame. The output shaft of the motor passes through the frame and is connected to a turntable.

[0012] As a preferred option, to enhance safety, two protective cabinet doors are hinged at the rear of the frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This structure ensures that the paper can be smoothly and accurately pushed out from between the two first pressure rollers by setting a horizontal pusher assembly on the side between the two first pressure rollers, which further improves the paper output accuracy and avoids the problem that "after long-term use, the gap between the pressure rollers is easy to loosen. Once loosened, the paper is not easy to be output from between the second and third pressure rollers on the lower right side.

[0025] Example 1

[0026] Please see Figures 1-8The disposable paper towel folding device disclosed in this embodiment includes a frame 1. From left to right, the frame 1 is equipped with a feeding mechanism 2 for winding paper, a folding mechanism 3, a first pressing mechanism 4, a conveying mechanism 5, and a second pressing mechanism 6. The second pressing mechanism 6 includes a support base 601, second pressing rollers 602, first pressing rollers 603, a drive gear 604, a drive mechanism 605, a metal longitudinal cutter 606, a cutter drive plate 607, a cutter drive arm 608, a turntable 609, and a motor 610. The support base 601 has two rotatable second pressing rollers 602 and two first pressing rollers 603. The two second pressing rollers 602 are placed side-by-side, one above the other, and the two first pressing rollers 603 are placed side-by-side, one above the other, with the first pressing rollers 603 located below the second pressing rollers 602. The second pressing rollers 602 and the first pressing rollers 603 are... Each end of 03 is provided with a drive gear 604, and adjacent drive gears 604 are connected for transmission. One of the drive gears 604 is connected to a drive mechanism 605 located behind the frame 1. The metal longitudinal cutter 606 is provided between the second pressure roller 602 and the first pressure roller 603 above. One end of the metal longitudinal cutter 606 is connected to the cutter drive plate 607. One end of the surface of the cutter drive plate 607 is connected to one end of the cutter drive arm 608. The other end of the cutter drive arm 608 is eccentrically hinged to the surface of the turntable 609. The motor 610 is fixed at the rear of the frame 1. The output shaft of the motor 610 passes through the frame 1 and is connected to the turntable 609. In order to play a guiding role, a longitudinal guide rail 611 is also provided at the front end of the frame 1. The cutter drive plate 607 is slidably connected to the longitudinal guide rail 611.

[0027] A horizontal pusher assembly 7 is located below a second pressure roller 602. The horizontal pusher assembly 7 is used to accurately push the paper between the second pressure roller 602 and the first pressure roller 603 into the space between the two first pressure rollers 603. The horizontal pusher assembly 7 includes a metal transverse pusher 701, a pusher drive plate 702, a pusher drive arm 703, and a motor 704. The motor 704 is located on the back of the frame 1. The output shaft of the motor 704 passes through the frame 1 and is connected to a turntable 705. One end of the pusher drive arm 703 is eccentrically connected to the front end of the turntable 705, and the other end of the pusher drive arm 703 is connected to the pusher drive plate 702. The metal transverse pusher 701 is provided on the pusher drive plate 702. In order to provide guidance, one or more horizontal guide rails 706 are also provided at the front end of the frame 1. The pusher drive plate 702 is slidably connected between the horizontal guide rails 706.

[0028] like Figure 7 , Figure 8As shown, preferably, in order to further achieve the guiding function, a positioning seat 8 is also provided at the front end of the frame 1. The support seat 601 is fixed on the positioning seat 8, and a limiting seat 9 is also provided on the positioning seat 8. One or more partitions 10 are provided at intervals on the limiting seat 9. The end of the metal transverse pusher 701 near the first pressing roller 603 is also provided with a guide notch 11 that facilitates the insertion of the partition 10. Each partition 10 is provided with an arc-shaped notch 101 above it to facilitate the insertion of the guide notch 11. The above structural arrangement can ensure that the metal transverse pusher 701 will not shift its position when moving horizontally, thus affecting the final paper output accuracy and further improving the guiding function of the horizontal movement of the metal transverse pusher 701.

[0029] As a preferred option, to improve safety, two protective cabinet doors 12 are hinged at the rear of the frame 1. By adding protective cabinet doors 12, the drive mechanism 605, motor 610 and motor 704 set at the rear are hidden, thereby further improving safety.

[0030] The working principle of this structure is as follows:

[0031] First, the feeding mechanism 2 gradually conveys the tissue paper to be folded towards the folding mechanism 3. The folding mechanism 3, equipped with two folding mechanisms, causes the edges of the tissue paper to fold downwards after passing through the first folding mechanism, creating the first initial fold crease. Then, the edges of the tissue paper continue to fold downwards after passing through the second folding mechanism, creating the second fold crease. The tissue paper is then folded along this second crease, completing the two folds. However, since the folds are still prone to unfolding after folding, further flattening is required. The tissue paper, which needs to be pressed, is continuously pressed by the first pressing mechanism 4. The crease position is fixed so that the entire paper crease position will not curl up. After the paper towel is initially compressed, it passes the surface of the first conveyor belt 52. When the compressed paper passes the surface between the two upper and lower distributed second pressing rollers 602 for the first time through the conveyor mechanism 5, it will play a clamping and conveying role. After passing one end distance, the second motor 610 works, driving the second turntable 609 to rotate, and synchronously driving the cutter drive arm 608 to rotate. The cutter drive arm 608 will drive the cutter drive plate 607 to slide. During the sliding process of the cutter drive plate 607, it will drive the metal longitudinal cutter 606 to move downward to cut the paper towel after it has been compressed and folded. After cutting, it will move downward to the right.

[0032] Then, the drive motor 704 operates, driving the turntable 705 to rotate, which in turn drives the pusher drive arm 703 to rotate. The pusher drive arm 703 drives the pusher drive plate 702 to move horizontally along the horizontal guide rail 706, ultimately pushing the downward-extending paper between the two first pressing rollers 603 on the right. This ensures that the folded paper can be smoothly and accurately pushed out between the two first pressing rollers 603 and fall into the next process. Therefore, this structure ensures that the paper can be smoothly and accurately pushed out between the two first pressing rollers 603 by setting the horizontal pusher assembly 7 on the side between the two first pressing rollers 603, further improving the paper output accuracy. It will not cause the problem that "after long-term use, the gap between the pressing rollers is easy to loosen. Once loosened, the paper will not be easily output from between the second and third pressing rollers on the lower right. Instead, it will be directly transported by the cutter drive plate to the gap between the left and right pressing rollers below, and will not be able to accurately reach the surface of the second conveying mechanism". It should also be noted that the specific structure and working principle of the feeding mechanism 2, folding mechanism 3, first pressing mechanism 4, conveying mechanism 5, and second pressing mechanism 6 can be referred to the contents of the prior art document mentioned in the background art. It belongs to conventional technology and therefore will not be described in detail.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
