Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of auxiliary accessories for film applicators, specifically to a bubble bag double release film applicator. Background Technology
[0002] Release film is a type of plastic film with specific surface properties that give it low or no adhesion when in contact with other materials under limited conditions. The primary function of bubble wrap is to provide cushioning and protection, preventing product damage during transportation. However, in certain situations, to meet additional cushioning needs, or when printing patterns or text on bubble wrap to ensure printing quality and prevent ink penetration into the bubble wrap, release film needs to be applied before the bubble wrap absorbs air bubbles. However, before the bubble wrap enters the laminator to be laminated with the release film, the surface of the bubble wrap is prone to dust and other contaminants, leading to the formation of air bubbles after the film is applied. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a bubble bag double release film applicator to solve the problems mentioned in the background art.
[0004] To achieve this objective, the present invention adopts the following technical solution:

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0028] like Figure 1 and Figure 2 As shown, this utility model provides a bubble bag double release film application device, including a bubble bag application machine 1, a bubble bag surface treatment mechanism 2 is provided at the right feed port of the bubble bag application machine 1, and a film bubble treatment mechanism 3 is provided at the left discharge port of the bubble bag application machine 1.
[0029] like Figure 3 As shown, the bubble bag surface treatment mechanism 2 specifically includes a bottom plate 21 and a top plate 23. A side plate 22 is fixed at the front and back positions of the bottom plate 21 and the top plate 23, which are close to each other. The bottom plate 21 and the top plate 23 are respectively embedded and fixed with a bottom air duct 210 and a top air duct 25. A centrifugal fan 26 is fixedly connected to the top surface of the top plate 23. The air outlet port of the centrifugal fan 26 is fixedly connected to an air pipe 28 through a pipe joint. The end of the air pipe 28 away from the centrifugal fan 26 passes through the interior of the bottom air duct 210. A manifold 27 is connected through the top surface of the air pipe 28. The end of the manifold 27 away from the centrifugal fan 26 passes through the interior of the top air duct 25.
[0030] like Figure 4 As shown, the membrane bubble treatment mechanism 3 specifically includes a square frame 31 and two plastic rollers 32 rotatably connected in the inner cavity of the square frame 31. The outer surface of each plastic roller 32 is provided with two mutually mirror-symmetrical threaded grooves 33.
[0031] The bottom plate 21 and the top plate 23 each have rectangular through holes in their inner middle sections for the bottom air duct 210 and the top air duct 25 to pass through and be fitted into. Seven to ten inclined plates 29 are fixed inside the adjacent ports of the bottom air duct 210 and the top air duct 25, with each inclined plate 29 forming an angle of 20-30° with the horizontal plane. These plates guide the airflow inside the top air duct 25 and the bottom air duct 210 towards the feeding direction of the bubble wrap applicator 1. Circular holes are formed on the distant surfaces of the bottom air duct 210 and the top air duct 25, and each circular hole contains a sealing ring that fits the outer surface of the manifold 27 and the air pipe 28.
[0032] Two rubber rollers 24 are rotatably connected to the side surfaces of the side plates 22 that are close to each other, and the rubber rollers 24 have a gap of 0.5-1.0 cm between them to allow the bubble bag to pass through the gap. The left side surface of the bubble bag laminating machine 1 is provided with a feeding port for the bubble bag to enter, and the right side surface of the bubble bag laminating machine 1 is provided with a discharging port for the bubble bag to be discharged after the release film has been applied.
[0033] The right side surfaces of the base plate 21 and the top plate 23 are fixedly connected to the side wall of the feed port of the bubble wrap applicator 1, and the left side surface of the square frame 31 is fixedly connected to the side wall of the discharge port of the bubble wrap applicator 1. The front and rear ends of the plastic roller 32 are rotatably connected to the front and rear side walls of the inner cavity of the square frame 31, respectively, and the plastic rollers 32 have a gap of 0.5-1.0cm between each other, which is used for the bubble wrap to pass through the gap after the release film is applied.
[0034] Based on the above-described preferred technical solution, the workflow of this technical solution is explained as follows:
[0035] Before the bubble bag enters the machine body through the feed port on the left side of the bubble bag laminating machine 1 for lamination, the bubble bag will pass between the rubber rollers 24. Due to the blowing of the centrifugal fan 26, the airflow inside the top air duct 25 and the bottom air duct 210 will be blown to the upper and lower surfaces of the bubble bag by the guide plate 29, thereby blowing away the dust on the surface of the bubble bag and preventing the formation of air bubbles between the film layer and the bubble bag due to dust.
[0036] After the film application system inside the bubble bag laminating machine 1 attaches the release film to the upper and lower surfaces of the bubble bag, the film-applied bubble bag will pass through the plastic rollers 32. During the passage of the bubble bag, the plastic rollers 32 are rotated, thereby pushing and stretching the bubble bag outward through the threaded grooves 33. The pushing method eliminates any air bubbles that may be formed between the film layer and the bubble bag.
[0037] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
