Abstract
Description
Technical Field
[0001] This utility model relates to the field of bubble wrap processing equipment, and in particular to a device for flattening and applying adhesive to the side of bubble wrap. Background Technology
[0002] Currently, bubble wrap is widely used in packaging, cushioning, and protection. Conventional bubble wrap is typically used directly in its original state without any structural modifications. However, as customers increasingly demand greater diversity and functionality in protective materials, traditional bubble wrap has limitations in certain applications, such as difficulty in adhering the edges and its inability to be used directly as a protective film.
[0003] Therefore, there is an urgent need for a simple and adaptable processing device that can integrate edge flattening and adhesive application during bubble wrap production, thereby improving the functionality and applicability of bubble wrap. Utility Model Content
[0004] This invention addresses the shortcomings of existing technologies by providing a device for flattening and applying adhesive to the side of bubble wrap.
[0005] To solve the above-mentioned technical problems, this utility model achieves its solution through the following technical solution:
[0006] A bubble wrap side flattening and adhesive applicator includes a frame, wherein the bubble wrap is continuously conveyed in roll form; along the conveying direction of the bubble wrap roll, a flattening mechanism and a double-sided adhesive applicator are sequentially arranged on the frame.
[0007] The flattening mechanism is used to flatten the bubbles on both sides of the bubble wrap edge. It includes an upper pressure roller and a lower roller, with the upper roller located above the bubble wrap conveying path and the lower roller located below. The width of at least one of the upper and lower rollers corresponds to the side width of the bubble wrap. The upper and / or lower rollers corresponding to the side width of the bubble wrap are respectively positioned on the left and right sides of the bubble wrap conveying path. When the bubble wrap passes through, the distance between the upper and lower rollers is less than the thickness of the bubble wrap that has not passed through the flattening mechanism. By flattening the edges of the bubble wrap and attaching double-sided tape, it can be used directly as a protective film. The device can be integrated into a bubble wrap production line to achieve continuous production, improve production efficiency, and expand the application scenarios of bubble wrap.
[0008] Preferably, the double-sided adhesive applicator is used to apply double-sided adhesive to the flattened sides; it includes a double-sided adhesive roll, a bubble wrap conveying roller, and a pressure roller located downstream of the double-sided adhesive roll; the double-sided adhesive rolls on the left and right sides are respectively located above the sides of the bubble wrap; the pressure roller cooperates with the bubble wrap conveying roller to press the double-sided adhesive output from the double-sided adhesive roll onto the sides of the bubble wrap flattened by the flattening mechanism.
[0009] Preferably, a heating mechanism is also included, comprising upper and lower pressure plates with a channel between them for the bubble wrap to pass through. At least one of the upper and lower pressure plates can generate heat. Preheating is to ensure that after the upper and lower rollers press the edges of the bubble wrap, the bubble wrap remains deformed and does not spring back, remaining flattened as it enters the station of the double-sided adhesive applicator.
[0010] Preferably, the pressure plate is a strip extending along the conveying direction of the bubble wrap roll, and the width of the pressure plate corresponds to the side width of the bubble wrap.
[0011] Preferably, the upper pressure rollers correspond to the side width of the bubble wrap, and the upper pressure rollers on the left and right sides are connected to the lower pressure power source.
[0012] Preferably, the lower roller is connected to a rotary power source for driving the bubble wrap forward.
[0013] Preferably, the upper pressure rollers on the left and right sides are mounted on the mounting rollers, and mounting blocks are fixedly connected to both ends of the mounting rollers. The frame is provided with vertically extending guide grooves that cooperate with the mounting blocks, and the mounting blocks are connected to the lower pressure power source.
[0014] Preferably, the downward pressing power source is a cylinder located on the left and right sides respectively, with the cylinders on both sides operating synchronously. The coordination between the synchronous cylinder pressing and the adjustment structure ensures consistency in product flattening and adhesive application.
[0015] This utility model, by adopting the above technical solution, has significant technical effects:
[0016] This utility model relates to a processing device for flattening bubble wrap and applying double-sided tape, which solves the problem in the prior art that the edges of bubble wrap are not easy to stick and require manual operation. By adding flattening during the production process of bubble wrap, only the bubbles on both sides of the bubble wrap are flattened, while the middle part remains in a bubble state, so that the bubble wrap can be used directly as a protective film. Double-sided tape is then applied to the flattened area for easy adhesion. Subsequently, the bubble wrap is used as a protective film and pasted onto the surface of the object being protected.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.
[0022] Example 1
[0023] A device for flattening and applying adhesive to the sides of bubble wrap, such as Figure 1-3 As shown, the machine includes a frame 1, in which bubble wrap is continuously conveyed in roll form; along the conveying direction of the bubble wrap roll, a flattening mechanism and a double-sided adhesive applicator are sequentially arranged on the frame 1.
[0024] The flattening mechanism is used to flatten the bubbles on both sides of the bubble film; it includes an upper pressure roller 21 and a lower roller 22, the upper pressure roller 21 being located on the upper side of the bubble film conveying path and the lower roller 22 being located on the lower side of the bubble film conveying path; the width of at least one of the upper pressure roller 21 and the lower roller 22 corresponds to the side width of the bubble film; the upper pressure roller 21 or / and the lower roller 22 corresponding to the side width of the bubble film are respectively disposed on the left and right sides of the bubble film conveying path; when the bubble film passes through, the distance between the upper pressure roller 21 and the lower roller 22 is less than the thickness of the bubble film that has not passed through the flattening mechanism.
[0025] The double-sided adhesive applicator is used to apply double-sided adhesive to the flattened sides of the bubble wrap; it includes a double-sided adhesive roll 31, a bubble wrap conveying roller 32, and a pressure roller 33 located downstream of the double-sided adhesive roll; the double-sided adhesive rolls 31 on the left and right sides are respectively located above the sides of the bubble wrap; the pressure roller 33 cooperates with the bubble wrap conveying roller 32 to press the double-sided adhesive output from the double-sided adhesive roll 31 onto the sides of the bubble wrap flattened by the flattening mechanism.
[0026] It also includes a heating mechanism, which includes upper and lower pressure plates 41 respectively, with a channel 42 formed between the upper and lower pressure plates 41 for the bubble film to pass through, and at least one of the upper and lower pressure plates 41 can generate heat.
[0027] The pressure plate 41 is a strip extending along the conveying direction of the bubble wrap roll, and the width of the pressure plate 41 corresponds to the side width of the bubble wrap.
[0028] In one embodiment, the upper pressure roller 21 corresponds to the side width of the bubble wrap, and the upper pressure rollers 21 on both the left and right sides are connected to a downward pressure power source 23. The lower roller 22 cooperates with the upper pressure roller 21; the lower roller 22 can be the same width as the upper pressure roller 21, or it can be a single roller, cooperating with the upper pressure roller 21 on both sides. In another embodiment, the lower roller 22 corresponds to the side width of the bubble wrap, and the lower rollers 22 on both the left and right sides are connected to an upward pressure power source. The upper pressure roller 21 cooperates with the lower roller 22; the upper pressure roller 21 can be the same width as the lower roller 22, or it can be a single roller, cooperating with the lower roller 22 on both sides.
[0029] The lower roller 22 is connected to a rotary power source 24 for driving the bubble film forward.
[0030] The upper pressure rollers 21 on the left and right sides are mounted on the mounting rollers 25. The two ends of the mounting rollers 25 are fixedly connected to the mounting blocks 251. The frame 1 is provided with vertically extending guide grooves 11 that cooperate with the mounting blocks 251. The mounting blocks 251 are connected to the lower pressure power source 23.
[0031] The downward pressure power source 23 consists of cylinders located on the left and right sides, with the cylinders on both sides operating synchronously. The cylinders are controlled by an air pump and connected to rollers to adjust the pressure applied by the rollers to the bubble wrap. The synchronous downward pressure of the cylinders ensures the uniformity of the flattening process.
[0032] Working principle: The heating mechanism includes upper and lower pressure plates 41. Bubble film, driven by the bubble film conveying roller 32, passes through a channel 42 formed between at least one of the heat-generating upper and lower pressure plates 41. It then enters a flattening mechanism to flatten the bubbles on both sides of the bubble film. This mechanism includes an upper pressure roller 21 and a lower roller 22. The upper pressure roller 21 is located on the upper side of the bubble film conveying path, and the lower roller 22 is located on the lower side. The width of at least one of the upper pressure roller 21 and the lower roller 22 corresponds to the width and position of the bubble film's side edge. This ensures that when the two rollers work together to apply pressure to the bubble film, only the side edges are flattened, while the middle portion remains in a bubble state, thus protecting the attached object during subsequent use. The bubble wrap continues to be conveyed downstream to the double-sided adhesive applicator. The double-sided adhesive roll (31) is supplied, and the pressure roller (33) applies double-sided adhesive to the flattened edges of the bubble wrap, making it easy to tear off later. The preheating is to ensure that the bubble wrap remains deformed and does not spring back after the upper pressure roller 21 and lower roller 22 press the edges of the bubble wrap, keeping it flat as it enters the station of the double-sided adhesive applicator. After the double-sided adhesive is applied, the bubble wrap can be rolled up and collected, or it can be sliced with a cutter or cut with a spot cutter and collected. This will not be elaborated here.
[0033] The bubble wrap is continuously conveyed in roll form. Rollers are positioned in the bubble wrap's travel path to apply pressure to both sides of the bubble wrap, flattening the edges of the conveyed bubble wrap. A double-sided adhesive applicator is positioned behind the rollers to apply double-sided adhesive to one edge of the flattened bubble wrap.
[0034] The power source can be a cylinder, an electric motor, or a cylinder and an electric motor that use gears and racks, lead screws and nuts, or sliders and guide rails to transmit motion. Rotation can be achieved by the electric motor driving the synchronous pulley to rotate, which in turn drives the belt mounted on the synchronous pulley to rotate.
