Description

Technical Field

[0001] The utility model is applicable to the technical field of plastic film bag-making equipment, and provides a folding frame for multi-specification bubble film and pearl cotton bag-making machines. Background Technique

[0002] Bubble film and pearl cotton packaging bags are often used as the outer packaging for express delivery items. They are usually made by folding and sealing the edges of a flat bubble film roll or pearl cotton roll. They have the advantages of anti-drop and anti-breakage, etc., and can reduce the impact of various improper operations during the express sorting and transportation process on the express items. During the production process of bubble film and pearl cotton packaging bags, an isosceles triangular frame is usually used to achieve the folding operation of the bubble film and pearl cotton substrates. Specifically, when the bubble film and pearl cotton substrates pass through the triangular frame, the left and right sides of the bubble film and pearl cotton substrates are respectively pulled down along the left and right hypotenuses of the triangular frame. With continuous pulling, the bubble film and pearl cotton substrates form a fold line at the intersection of the two hypotenuses of the triangular frame, and finally form a folded packaging bag base material after being pressed by the horizontal pressure roller below the intersection. However, this method has some problems. First of all, this isosceles triangular frame cannot limit the left and right sides of the bubble film and pearl cotton substrates, and the widths of the bubble film and pearl cotton substrates are different. Therefore, it is difficult for traditional equipment to ensure that the bubble film and pearl cotton substrates do not deviate during the processing, and it is necessary to manually pay attention to the operation situation at any time. Once deviation occurs, the feeding direction of the substrate is adjusted manually. Some equipment uses a limiting device to limit the two sides of the bubble film and pearl cotton substrates. However, this method either the limiting device is fixed to correspond to a bubble film and pearl cotton substrate of a single specification, or the limiting device needs to be manually adjusted after replacing different specifications of bubble film and pearl cotton substrates, and the operation is cumbersome. At the same time, after the left and right sides of the bubble film and pearl cotton substrates are respectively pulled down along the left and right hypotenuses of the triangular frame, the back of the bubble film and pearl cotton substrates has no support, and at this time, the bubble film and pearl cotton substrates are also prone to deviation, resulting in overlapping of some positions of the substrate on the surface of the packaging bag after subsequent pressing. Summary of the Utility Model

[0003] Based on the above problems, the utility model provides a folding frame for multi-specification bubble film and pearl cotton bag-making machines. By setting substrate limiting holes with different widths on the oblique folding triangular plate to limit the two sides of bubble film and pearl cotton substrates with different widths, it is ensured that the bubble film and pearl cotton substrates are not easily deviated during folding. At the same time, oblique first side guide plates and second side guide plates are arranged on both sides of the oblique folding triangular plate to form a back support during the folding process of the left and right sides of the bubble film and pearl cotton substrates.

[0004] In order to achieve the above object, the utility model provides the following technical solutions: A folding frame for multi-specification bubble film and pearl cotton bag-making machines, comprising:

[0005] Device bracket, used for fixedly installing various components, including a vertical bracket. Front and rear sides of the vertical bracket are respectively fixedly connected with a front bottom bracket and a rear bottom bracket. The front bottom bracket is provided with a folding and pressing mechanism, and the folding and pressing mechanism includes two folding rollers arranged in parallel at intervals.

[0006] Base material folding mechanism, fixedly arranged on the vertical bracket, includes an inclined folding triangular plate inclined relative to the horizontal plane. The inclined folding triangular plate includes two symmetrically arranged folding hypotenuses. The above two folding hypotenuses gradually decrease in distance from top to bottom and finally intersect above the gap between the two folding rollers. The inclined folding triangular plate is provided with several base material limiting holes arranged in parallel from top to bottom. The base material limiting holes are long strip-shaped holes.

[0007] Several feeding guide rollers, arranged in parallel from top to bottom on the vertical bracket. The several feeding guide rollers are arranged in one-to-one correspondence with the several base material limiting holes.

[0008] Further, widths of the several base material limiting holes gradually decrease from top to bottom.

[0009] Further, the base material folding mechanism further includes a first side guide plate and a second side guide plate. The first side guide plate includes an intersecting first bottom edge and a first side edge. The second side guide plate includes an intersecting second bottom edge and a second side edge. The first side guide plate and the second side guide plate are symmetrically arranged on both sides of the inclined folding triangular plate. And the first bottom plate and the second bottom edge coincide above the gap between the two folding rollers. The first side edge and the second side edge respectively coincide with the two folding hypotenuses of the inclined folding triangular plate.

[0010] Further, the front bottom bracket is provided with a discharge guide roller, and the discharge guide roller is arranged in parallel with the folding rollers.

[0011] Further, the rear bottom bracket is provided with a main feeding roller, and the main feeding roller is arranged in parallel with the feeding guide rollers.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. In the solution of the present utility model, by arranging several base material limiting holes with gradually decreasing widths from top to bottom on the inclined folding triangular plate to correspond to bubble films and pearl cotton base materials with different widths, and limiting the two side edges of the base material through the base material limiting holes, the bubble films and pearl cotton base materials are kept in a non-deviating state during the feeding and conveying process. In this way, the function of producing bubble films or pearl cotton packaging bags with multiple specifications using the same inclined folding triangular plate is also realized.

[0014] 2. A first side guide plate and a second side guide plate are respectively arranged on both sides of the oblique folding triangle plate. When the left and right sides of the bubble film and the pearl cotton substrate are respectively pulled down along the left and right oblique sides of the tripod until they are folded, the first side guide plate and the second side guide plate on both sides will always support the back of the bubble film and the pearl cotton substrate, so that the bubble film and the pearl cotton substrate can reduce the up and down jumping during the dragging process so that they are always in an unfolded and flat state, improving the problem of substrate overlap caused by lack of support for the substrate.

[0020] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0021] For example, see the attached Figure 1 The utility model provides a folding frame for a multi-specification bubble film and pearl cotton bag making machine, including an equipment support 1 and a substrate folding mechanism 2, as shown in the attached Figure 2 As shown, the equipment support 1 includes a vertical support 11, and the front and rear sides of the vertical support 11 are respectively fixedly connected to a front bottom support 12 and a rear bottom support 13, and the front bottom support 12 is provided with a folding pressing mechanism 3, and the folding pressing mechanism 3 includes two parallel folding pressing rollers 31 arranged at intervals, and the folded bubble film and pearl cotton substrate 7 can be pressed and shaped when passing through the gap between the two folding pressing rollers 31; as shown in the attached Figure 3As shown in the figure, the substrate folding mechanism 2 is fixedly arranged on the vertical bracket 11 and includes an inclined folding triangular plate 21 inclined relative to the horizontal plane, a first side guide plate 22 and a second side guide plate 23. The inclined folding triangular plate 21 includes two symmetrically arranged folding hypotenuses. The distance between the two folding hypotenuses gradually decreases from top to bottom and finally intersects above the gap between the two folding rollers 31. A plurality of substrate limiting holes 24 with gradually decreasing widths are arranged in parallel from top to bottom on the inclined folding triangular plate 21. The substrate limiting holes 24 are long strip-shaped holes. The bubble film and the pearl cotton substrate 7 of different specifications correspond to the substrate limiting holes 24 of different widths. When the bubble film and the pearl cotton substrate 7 of the corresponding width pass through the substrate limiting holes 24, the two sides are limited by the two side walls of the substrate limiting holes 24. In this way, during the continuous feeding process, the bubble film and the pearl cotton substrate 7 are not easily displaced and can always maintain the most suitable feeding direction. The first side guide plate 22 includes an intersecting first bottom edge and a first side edge. The second side guide plate 23 includes an intersecting second bottom edge and a second side edge. The first side guide plate 22 and the second side guide plate 23 are symmetrically arranged on both sides of the inclined folding triangular plate 21, and the first bottom plate and the second bottom edge coincide above the gap between the two folding rollers 31. The first side edge and the second side edge coincide with the two folding hypotenuses of the inclined folding triangular plate 21 respectively. The left and right sides of the bubble film and the pearl cotton substrate 7 are pulled and folded downward at the two folding hypotenuses of the inclined folding triangular plate 21. As the continuous downward folding progresses, finally, the bubble film and the pearl cotton substrate 7 form a fold line at the intersection of the two folding hypotenuses. Before the left and right parts of the bubble film and the pearl cotton substrate 7 are completely overlapped, the backs of the left and right parts of the bubble film and the pearl cotton substrate 7 are always attached to the first side guide plate 22 and the second side guide plate 23 respectively. During this process, the first side guide plate 22 and the second side guide plate 23 will support the bubble film and the pearl cotton substrate 7 to ensure that the bubble film and the pearl cotton substrate 7 always remain flat and will not generate pulling creases due to pulling. A plurality of feeding guide rollers 6 are arranged in parallel from top to bottom on the vertical bracket 11. The plurality of feeding guide rollers 6 are arranged in one-to-one correspondence with the plurality of substrate limiting holes 24. The front bottom bracket 12 is also provided with a discharge guide roller 4. The discharge guide roller 4 is arranged in parallel with the folding rollers 31. The rear bottom bracket 13 is provided with a main feeding roller 5. The main feeding roller 5 is arranged in parallel with the feeding guide rollers 6.

[0022] The working principle of this embodiment is as follows:

[0023] Refer to the appendix Figure 4, first, rotate the suitable substrate limiting hole 24 according to the width specification of the bubble wrap and the EPE substrate 7, and then start the device. The bubble wrap and the EPE substrate 7 enter through the main feeding roller 5, and then enter the substrate limiting hole 24 after passing through the feeding guiding roller 6 adapted to the selected substrate limiting hole 24. After passing through the substrate limiting hole 24, pull the bubble wrap and the EPE substrate 7 obliquely downward along the surface of the inclined folding triangle plate 21. The left and right parts of the bubble wrap and the EPE substrate 7 form bends at the two folding hypotenuses. The backs of the folded bubble wrap and the EPE substrate 7 are respectively close to the first side guide plate 22 and the second side guide plate 23. With continuous downward pulling, the bubble wrap and the EPE substrate 7 form a folding line at the intersection of the two folding hypotenuses, and the left and right parts of the bubble wrap and the EPE substrate 7 completely overlap. Finally, after being pressed and shaped by the two folding pressing rollers 31 of the folding and pressing mechanism 3, it is discharged from the discharging guiding roller 4, so that the single-sided bubble wrap and the EPE substrate 7 can be folded into a double-layer bubble wrap or EPE packaging bag substrate.

[0024] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, so it cannot be understood as a limitation on the protection scope of the present invention: the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0025] The above is only a preferred embodiment of the present invention. Any person skilled in the art may modify the present invention by using the technical solutions described above or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement made according to the technical solution of the present invention falls within the scope of protection required by the present invention.
