Description

Technical Field

[0001] The utility model belongs to the technical field of packaging bag processing, and in particular relates to a packaging bag composite film conveying and pasting device. Background Art

[0002] Packaging film is a plastic film bag used to package products. Its main material is polyethylene resin. Packaging film has the advantages of high sealing, waterproof, acid and alkali corrosion resistance, so it is often used as the inner packaging of products in the industry.

[0003] In the production and processing of packaging bag films, in order to improve film performance, composite films are often used. That is, two or more films are bonded together and then transferred to hot pressing equipment for hot pressing into composite films to obtain films with improved performance.

[0004] In the production process, the two films are usually unrolled, bonded together and transferred to the hot pressing equipment for hot pressing. However, during the transmission process, the bonding degree is often not high due to the different film materials. During the transmission process, the film materials often gradually separate from the bonded state to the separated state. As a result, once the films are separated during the transmission process, relative misalignment is very likely to occur between the films. As a result, after hot pressing, the double-layer films cannot be completely and accurately covered together, thus forming irregular protrusions and the existence of single-layer film areas, resulting in unqualified composite film materials produced and processed.

[0005] Therefore, in the actual processing and production process, manual intervention is often used. However, due to the long transmission distance, especially the transmission between different workstations, it is difficult to monitor the separation status of the composite membrane in real time.

[0006] Based on the above background, the purpose of the utility model is to provide a packaging bag composite film conveying and laminating device.

[0007] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0040] Example 1

[0041] like Figure 1-5 As shown, a packaging bag composite film conveying and laminating device comprises a conveying frame, and both ends of the conveying frame are respectively equipped with film driving roller mechanisms 1; the composite film is conveyed by the film driving roller mechanisms 1.

[0042] Specifically, similar to the prior art, the film driving roller mechanism 1 uses friction drive to transport the double-layer film, and during the transport process, the films are initially pressed together. Specifically, the transport frame includes frame plates 141 spaced apart at the front and rear sides, and the film driving roller mechanism 1 is respectively fixedly assembled on the left and right ends of the frame plate 141. That is, the left and right ends of the frame plate 141 each have a film driving roller mechanism 1 that cooperates with each other.

[0043] The specific structure of the film driving roller mechanism 1 is as follows:

[0044] The film driving roller mechanism 1 includes a driving frame 14 fixed on a frame plate 141; an elastic conveying roller 12 with upper and lower frictional contact is rotatably connected between the driving frame 14 (same as the existing method, the above-mentioned elastic conveying roller 12 is made of rubber material, and the front and rear side walls thereof are respectively fixed with upper rotating shafts, and the same as the existing method, the rotating shaft is rotatably connected to the driving frame 14, and the driving frame 14 is installed with an adapted bearing, and a pulley is connected to the rotating shaft at the rear end position, and the pulleys at the same height are linked by a transmission belt transmission). At the same time, same as the existing method, a driving motor 13 is assembled and connected to the pulley to drive the pulley to rotate. There are two driving motors 13, that is, the upper two driving pulleys are driven by one driving motor 13, and the lower two driving pulleys are driven by one driving motor 13 (the driving motor 13 at this position is not drawn).

[0045] According to the existing method, the driving motor 13 is fixedly installed through the motor frame 11.

[0046] During the working process, the two layers of films to be hot pressed move from the film driving roller mechanism 1 on one side to the film driving roller mechanism 1 on the other side. When passing through the film driving roller mechanism 1, the two layers of film are in elastic extrusion contact with the elastic conveying roller 12, so that the elastic conveying roller 12 synchronously gives friction power to the film to transport the film. The advantage of this method is that the film material is pulled synchronously by the film driving roller mechanisms 1 on both sides, and the tension is relatively high, and it is not easy to separate.

[0047] Example 2

[0048] like Figure 1-5 As shown, based on the structure of Example 1, in order to avoid separation of the film material during transportation and maintain a high degree of adhesion, the packaging bag composite film conveying and bonding device also includes an air blowing bonding mechanism assembled on the frame.

[0049] Specifically, the air-blowing laminating mechanism comprises air-blowing tube racks 2 spaced apart from each other, and the film passes through between the air-blowing tube racks 2; and a plurality of air-flow holes 211 are respectively provided on the side walls of the air-blowing tube racks 2 facing each other.

[0050] The shape of the air blowing tube frame 2 is:

[0051] The air blowing tube rack 2 includes a plurality of horizontally arranged straight tubes 21, and the straight tubes 21 are connected to each other through a bend 22; at the same time, according to the existing method, an air inlet connection nozzle 212 is welded to the air inlet end of the air blowing tube rack 2. According to the existing method, the air inlet connection nozzle 212 is connected to an external air pipe, such as an external air inlet pipe, and the external air inlet pipe is installed on an air pump, so that during the working process, under the action of the air pump, the air blowing tube rack 2 at the upper position pumps out a downward large area of ​​the sinking airflow, while the air blowing tube rack 2 at the lower position pumps out an upward large area of ​​the rising airflow. The airflow is used to resist the membrane material on the upper and lower surfaces of the film to ensure that the membrane material is "clamped" between the airflow layers, thereby preventing them from separating.

[0052] Example 3

[0053] like Figure 1-5 As shown, based on the structure of Example 1, the packaging bag composite film conveying and laminating device of this embodiment also includes a film initial laminating mechanism installed on the frame. After the film in the transmission process is initially laminarized by the film initial laminating mechanism, it passes between the air blowing tube racks 2 and is laminarized again.

[0054] Specifically, the film initial laminating mechanism includes laminating components symmetrically arranged up and down; the laminating components are fixedly installed between the driving frames 14.

[0055] The fitting parts include vertical seats 31 respectively fixedly connected to the driving frame 14, and the vertical seats 31 are provided with rectangular openings, and the inner screw 311 is fixedly connected in the rectangular openings, and the inner slide seat 32 is slidably connected to the inner screw 311, and the inner screw 311 is threadedly connected with a blocking nut for blocking the inner slide seat 32. This method realizes sliding adjustment of the spacing between the fitting parts and the roller body, and is convenient for changing the fitting position of the mold material.

[0056] A connecting beam plate 33 is fixedly connected between the inner slide seats, and a bonding plate 331 is integrally formed at the bottom of the connecting beam plate 33 and is arranged obliquely outward. The bonding plate 331 is made of elastic rubber.

[0057] Since the laminating parts are symmetrical up and down, the symmetrically inclined laminating plates 331 are close to each other and form a gap. At this time, the double-layer film passes through the gap between the laminating plates 331, and with the help of the laminating plates 331 with a longer length, the film material is initially laminated, thereby ensuring a higher degree of lamination of the subsequent film material.

[0058] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
