Description

Technical Field

[0001] This utility model relates to the field of sterilization-grade packaging product processing technology, specifically to a breathable patch packaging film patching device. Background Technology

[0002] Sterilization and disinfection of hygiene products (such as sanitary napkins, diapers, medical dressings, and disinfectant wipes) requires the use of gases such as ethylene oxide for sterilization and disinfection during processing. The principle of this sterilization and disinfection process is as follows: Traditional sterilization and disinfection of hygiene products mainly rely on the breathability of their outer packaging film. The product is sealed with an outer packaging film (such as POPP polypropylene, PA polyamide, etc.), and then the sealed product is placed in a sterilization and disinfection chamber. The ethylene oxide and other gases in the sterilization and disinfection chamber permeate through the outer packaging film into the packaging bag to sterilize and disinfect the sanitary napkins and other products. After a certain period of time, the product is taken out and placed in a well-ventilated area, which allows the ethylene oxide and other gases in the packaging bag to evaporate again through the outer packaging film. After a certain period of time, the product can be shipped out for sale. However, the aforementioned traditional process relies entirely on the breathability of the outer packaging film to allow gases such as ethylene oxide to pass through. This process is time-consuming, and the ethylene oxide and other gases inside the packaging bag do not evaporate sufficiently. Therefore, based on the needs of downstream manufacturers, a new process has emerged in the field of outer packaging film processing technology: "perforating the outer packaging film – attaching a breathable sheet through the perforation." Traditionally, labeling machines exist, but these machines perform indirect labeling and are mainly used for labeling non-film products. The principle is that the labeling machine peels the label from the release paper using a peeling plate, then uses a matching negative pressure suction cup device to hold the back of the label, then a translation mechanism transfers the label above the object, and a lifting mechanism presses the label onto the item to complete the labeling. However, the new process for continuous labeling after perforating the outer packaging film needs to solve the following problem to achieve the production efficiency required by current production lines: the existing negative pressure suction cup device cannot solve the technical problem of continuously conveying the packaging film for attaching the breathable sheet. Utility Model Content

[0003] This utility model provides a breathable patch packaging film patching device to solve the problems in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A breathable patch packaging film applicator includes a labeling machine and a label-receiving and pressing device. The label-receiving and pressing device includes a packaging film conveying and supporting assembly and a breathable patch pressing assembly. The packaging film conveying and supporting assembly includes a first packaging film guide roller and a second packaging film guide roller. The first packaging film guide roller is positioned in front of the label peeling plate of the labeling machine, facilitating the initial application of the peeled breathable patch onto the packaging film. The breathable patch pressing assembly is positioned above the packaging film conveying and supporting assembly and includes a point-pressing assembly and a roller pressing assembly. The point-pressing assembly includes a point-pressing rotating roller and a high-frequency telescopic assembly. The high-frequency telescopic assembly controls the point-pressing rotating roller to move rapidly up and down, thereby pre-pressing the breathable patch initially adhered to the packaging film. The roller pressing assembly includes a pressure roller, which is correspondingly positioned at the second packaging film guide roller, forming a set of pressure rollers to forcefully press the breathable patch that has been pre-pressed onto the packaging film.

[0006] Optionally, the packaging film conveying support assembly further includes a support plate, which is disposed directly below the point-pressure rotating roller.

[0007] Optionally, a drive motor is provided on one side of the pressure roller and / or the second steering roller of the packaging film.

[0008] Optionally, the breathable patch pressing assembly includes a fixed bracket body, and the high-frequency telescopic assembly includes a swing telescopic crossbar. The point-pressure rotating roller is adjustablely mounted on the swing telescopic crossbar. Movable grooves are provided on both sides of the fixed bracket body, and the two ends of the swing telescopic crossbar are movably mounted in the movable grooves. A spring is provided at the lower part of the movable groove. A high-frequency pneumatic telescopic cylinder is provided directly above the swing telescopic crossbar. The swing telescopic crossbar is moved downward by applying pressure to it through the telescopic rod of the high-frequency pneumatic telescopic cylinder, and moved upward by the spring force after the high-frequency pneumatic telescopic cylinder is depressurized.

[0009] Optionally, the high-frequency pneumatic telescopic cylinder includes a cylinder body, and a piston, a lower telescopic rod, and an upper telescopic rod are arranged in the air chamber of the cylinder body; the lower telescopic rod and the upper telescopic rod are respectively connected to the lower part and the upper part of the piston; the upper middle part of the upper telescopic rod is provided with a venting groove, and when the upper telescopic rod moves downward, the lower part of the venting groove enters the air chamber to achieve venting.

[0010] Optionally, the top of the fixed bracket body is provided with a waist-shaped fixing hole, and the high-frequency pneumatic telescopic cylinder can be adjusted and fixed on the waist-shaped fixing hole through an "I"-shaped screw assembly.

[0011] Optionally, a guide elongated hole is provided directly above the movable groove; guide rods are provided at both ends of the upper side of the swing telescopic crossbar corresponding to the guide elongated hole.

[0012] Optionally, an electromagnetic valve is provided at the air inlet pipe of the high-frequency pneumatic telescopic cylinder.

[0013] Optionally, the point-pressing rotating roller can be rotatably fixed on the point-pressing fixing frame, and a point-pressing rotating roller drive motor is provided on one side of the point-pressing fixing frame.

[0014] It also includes mounting brackets, which are located on the left and right sides of the label pressing device.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention eliminates the need for traditional negative pressure suction cup devices. Instead, it directly uses the packaging film to receive the peeled breathable patch, then pre-presses it through high-frequency pressing, followed by strong roller pressing. This ensures that the breathable patch is reliably attached to the perforated area of ​​the packaging film, achieving the technical effect of attaching breathable patches while continuously conveying the packaging film.

[0024] like Figures 1-3 As shown, the breathable patch packaging film applicator includes a labeling machine 13 and a label-receiving and pressing device. The label-receiving and pressing device includes a packaging film conveying support assembly 1 and a breathable patch pressing assembly 7. The packaging film conveying support assembly 1 includes a first packaging film guide roller 10 and a second packaging film guide roller 3, as shown. Figure 1 As shown, the first steering roller 10 of the packaging film is positioned in front of the peeling plate 12 of the labeling machine, enabling the breathable patch to initially adhere to the packaging film after peeling. During installation, the first steering roller 10 of the packaging film should be placed as close as possible to the peeling plate 12. The working process of the labeling machine is as follows: the release paper is conveyed by the labeling machine to the peeling plate 12, and the peeling plate 12 bends downward, thereby peeling off the breathable patch at the tip of the peeling plate 12. At this time, the perforated packaging film 11 is laterally corrected and positioned, and then conveyed from bottom to top by the first steering roller 10 of the packaging film. After being peeled off, the breathable patch moves forward and contacts the perforated area of ​​the packaging film, thus achieving initial adhesion of the breathable patch to the packaging film. The breathable patch pressing assembly 7 is positioned above the packaging film conveying support assembly 1, as shown in the figure. Figures 1-2 As shown, it includes a point-pressing assembly and a roller-pressing assembly. The point-pressing assembly includes a point-pressing rotating roller 8 and a high-frequency telescopic assembly. The high-frequency telescopic assembly controls the point-pressing rotating roller to move up and down rapidly, thereby pre-pressing the breathable patch that has initially adhered to the packaging film. The roller-pressing assembly includes a pressure roller 6, which is correspondingly arranged at the second steering roller 3 of the packaging film, forming a set of pressure rollers to perform strong roller pressing on the breathable patch that has been pre-pressed onto the packaging film 11, so that the breathable patch adheres tightly to the packaging film 11.

[0025] Optional, such as Figure 1 As shown, the packaging film conveying support assembly 1 also includes a support plate 9, which is detachably fixed to the outer shell bracket of the packaging film conveying support assembly 1 by screws, and is correspondingly arranged directly below the point pressure rotating roller 8 to provide support for the packaging film 11.

[0026] Optionally, a drive motor 5 is provided on one side of the pressure roller 6 to provide continuous conveying driving force for the packaging film 11, or a drive motor 2 can also be provided on one side of the second steering roller 3 of the packaging film.

[0027] Optional, such as Figures 2-3 As shown, the breathable patch pressing assembly 7 includes a fixed support body 14, and the high-frequency telescopic assembly includes a swing telescopic crossbar 18. The point-pressing rotating roller 8 is adjustablely mounted on the swing telescopic crossbar 18. In this embodiment, as shown... Figure 2 As shown, the pressure roller 8 is rotatably fixed to the pressure fixing frame 17. A pressure roller drive motor 16 is provided on one side of the pressure fixing frame 17. In use, the pressure fixing frame 17 can be laterally adjusted and fixed to the swing telescopic crossbar 18 using screws 26. Because the opening positions of different products vary in actual packaging film production, adjustment is required for the opening positions of the packaging film 11. The purpose of providing the pressure roller drive motor 16 is to enable the pressure roller 8 to rotate along the direction of the packaging film 11 and at the corresponding conveying speed.

[0028] Movable grooves 21 are provided on both sides of the fixed bracket body 14. The two ends of the swing telescopic crossbar 18 are movably disposed in the movable grooves 21. A spring 20 is provided at the lower part of the movable groove 21. A high-frequency pneumatic telescopic cylinder 24 is provided directly above the swing telescopic crossbar 18. The swing telescopic crossbar is moved downward by applying pressure to it through the telescopic rod of the high-frequency pneumatic telescopic cylinder 24. After the high-frequency pneumatic telescopic cylinder is depressurized, the swing telescopic crossbar is moved upward by the elastic force of the spring.

[0029] Optionally, the high-frequency pneumatic telescopic cylinder includes a cylinder body, and a piston, a lower telescopic rod 27, and an upper telescopic rod 28 are arranged in the air chamber of the cylinder body; the lower telescopic rod 27 and the upper telescopic rod 28 are respectively connected to the lower part and the upper part of the piston; the upper middle part of the upper telescopic rod 28 is provided with a venting groove 30, and when the upper telescopic rod moves downward, the lower part of the venting groove 30 enters the air chamber to achieve venting. During installation, an electromagnetic valve (not shown) is installed at the air inlet pipe 25 of the high-frequency pneumatic telescopic cylinder 24. The electromagnetic valve is controlled by a control circuit and can be controlled by a timed opening and closing method. When the electromagnetic valve is opened, positive pressure gas enters the upper part of the piston of the high-frequency pneumatic telescopic cylinder 24, which in turn pushes the piston, the lower telescopic rod 27 and the upper telescopic rod 28 to move downward. At this time, the swing telescopic crossbar 18 is forced to move downward, and at the same time, the springs 20 at both ends are squeezed and contracted, which drives the point-pressure rotating roller 8 to move downward, so as to pre-press the breathable patch that has been initially adhered to the packaging film, and promote the breathable patch to further adhere to the packaging film. The next step is to close the solenoid valve. At this time, the upper telescopic rod 28 moves downward and the upper venting groove 30 moves into the air chamber of the cylinder, thereby venting and depressurizing the upper air chamber of the piston. The springs 20 at both ends then rebound, and the swing telescopic crossbar 18 is forced upward, driving the point-pressure rotating roller 8 to move upward. As the upper telescopic rod 28 moves upward, the lower end of the venting groove 30 moves outward. Then, the solenoid valve is reopened, and this cycle repeats. Using this technical solution, the point-pressure rotating roller 8 can perform high-frequency pressing on the breathable patch on the packaging film 11 during the conveying process, and the point-pressure rotating roller 8 rotates synchronously with the packaging film 11, significantly improving the pre-compression effect on the breathable patch and reducing the displacement of the breathable patch.

[0030] Optionally, the top of the fixed bracket body 14 is provided with an oblong fixing hole 29, and the high-frequency pneumatic telescopic cylinder can be adjusted and fixed on the oblong fixing hole through the "I"-shaped screw assembly 31 to adjust the position of the point pressure fixing bracket 17.

[0031] Optional, such as Figure 2 As shown, a guide elongated hole 22 is also provided directly above the movable groove 21; guide rods 15 are respectively provided at both ends of the upper side of the swing telescopic crossbar 18 corresponding to the guide elongated hole 22. This is to improve the smoothness of the swing telescopic crossbar 18 during the up and down swing process and prevent displacement.

[0032] like Figure 1 As shown, it also includes a mounting bracket 4, which is disposed on the left and right sides of the label pressing device and can be detachably fixed to one end of the production line through the mounting hole 4-1.
