Description

Technical Field

[0001] This utility model relates to the field of roll packaging technology, and in particular to a roll waterproof packaging device. Background Technology

[0002] Rolled materials are flexible building materials constructed in sheet form and capable of being rolled up. For ease of transport, they are typically packaged in reels. Before being packaged into reels, considering current common manufacturing processes, the rolls are likely soaked in a cooling water bed, meaning their surfaces are coated with cooling water before being wound into reels. For the two main surfaces of the sheet-like rolls, packaging processes / appliances usually include processes / drying rollers to absorb moisture from the main surfaces; however, current packaging processes / appliances lack dehydration methods for the various edges of the rolls, particularly the end edges when wound into reels. If the roll is packaged without removing moisture from the end edges, moisture will remain on the surface of the roll and be sealed by the packaging film or adhesive. On the one hand, the moisture will cause uneven shrinkage of the heat shrink film, resulting in an uneven packaging surface that affects the appearance of the roll packaging. On the other hand, moisture remaining on the surface of the roll for a long time may emit odors during transportation or storage, requiring additional deodorization when it is used, which increases the workload of on-site staff.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0023] The following is combined Figure 1 This invention describes a waterproof packaging device for roll materials.

[0024] Figure 1 This is a perspective view of the waterproof roll packaging device provided by this utility model, such as... Figure 1 As shown, the roll waterproof packaging device includes a main frame 1, an air shaft 2, a tape supply mechanism 3, and at least one nozzle 4.

[0025] An air shaft 2 is rotatably connected to the main frame 1. The air shaft 2 extends along a first direction X and is rotatable about the first direction X. The advantage of using the air shaft 2 here is that its separation and placement from the roll / reel can be accomplished in just a few seconds by inflation / deflation, and it can engage tightly with the roll / reel without disassembling any parts on the shaft end side. A tape supply mechanism 3 is movably connected to the main frame 1, and the tape supply mechanism 3 is positioned opposite the air shaft 2. Movement of the tape supply mechanism 3 relative to the main frame 1 allows it to approach or move away from the air shaft 2 to apply adhesive to the roll wound into a reel at the appropriate time, as will be described in detail below. At least one nozzle 4 is fixedly connected to the main frame 1, specifically positioned aligned with the corresponding end edge of the roll to be packaged along the first direction X. The nozzle 4 is used to blow dry air onto the corresponding end edge, thereby achieving dehydration of the end face of the reel.

[0026] Preferably, the waterproof roll packaging device further includes a controller (not shown). The controller is communicatively connected to at least one nozzle 4. The controller may be a programmable logic controller (PLC) or other commercially available controllers. When the roll to be packaged has been wound into a spool by the air-expanding shaft 2, the controller controls at least one nozzle 4 to blow air onto the corresponding end edges of the spool formed by the roll. In this way, moisture remaining on the roll, especially at its end edges along the first direction X, is dried by the nozzle 4.

[0027] In order for at least one nozzle 4 to perform an air blowing action on the end edge of the roll / reel, at least one nozzle 4 is connected to an external high-pressure air source. At the same time, as mentioned above, the separation and placement of the air shaft 2 from the roll / reel can be accomplished by inflation / deflation. For this purpose, the air shaft 2 is also fluidly connected to an external high-pressure air source. In other words, the inflation / deflation of the air shaft 2 also relies on an external high-pressure air source.

[0028] Based on this, the timing of inflation / deflation of the air shaft 2 can be controlled by the aforementioned controller, i.e., the controller is communicatively connected to the air shaft 2. When the air shaft 2 is winding the roll material being fed to it, the air shaft 2 needs to firmly hold the roll material. Therefore, the controller controls the air shaft 2 to inflate, with the inflation gas provided by an external high-pressure gas source. The inherent key on the air shaft 2 will protrude and press against the roll material wound on its outer circumference. When the air shaft 2 releases the packaged roll, the air shaft 2 needs to disengage from the roll material. Therefore, the controller controls the air shaft 2 to deflate, and the inherent key on the air shaft 2 will reset and disengage from the roll material, thereby removing the roll from the air shaft 2.

[0029] Preferably, the number of nozzles 4 is multiple, for example, three, four or more. The nozzles 4 are evenly distributed at two corresponding end edges aligned with the roll material to be packaged along the first direction X. For example, in a roll waterproofing packaging device equipped with three nozzles 4, two nozzles 4 are located at the first end edge aligned with the roll material to be packaged, while the remaining nozzle 4 is located at the second end edge aligned with the roll material to be packaged; in a roll waterproofing packaging device equipped with four nozzles 4, one pair of nozzles 4 are located at the first end edge aligned with the roll material to be packaged and on both sides of the horizontal axis of the air shaft 2, while another pair of nozzles 4 are located at the second end edge aligned with the roll material to be packaged and on both sides of the horizontal axis of the air shaft 2, and so on. In particular, each nozzle 4 is positioned such that the direction of the airflow it blows is in the same plane as the end face of the roll formed by the roll material. This allows the multiple nozzles 4 to perform blowing action on both end edges of the rolled roll.

[0030] Preferably, the tape supply mechanism 3 includes a swing shaft 31 and at least one tape applicator 32. The swing shaft 31 is rotatably connected to the main frame 1 about a first direction X, i.e., the swing shaft 31 is parallel to the air shaft 2. At least one tape applicator 32 extends radially along the swing shaft 31. Preferably, each tape applicator 32 also includes a tape applicator roller 33, which is arranged at the tip of the corresponding tape applicator 32. The rotation range of the swing shaft 31 can be set to 10°~15°. From the perspective of the first direction X, when the swing shaft 31 rotates clockwise around its virtual axis of rotation, the adhesive applicator 32 approaches the air shaft 2, which is positioned opposite it, until it comes into contact with the roll at the tip of the adhesive applicator 32. This applies the adhesive tape to the outer circumferential surface of the roll, which is made of rolled material, while the adhesive roller 33 firmly presses the adhesive tape onto the outer circumferential surface of the roll. When the air shaft 2 drives the roll to rotate more than one revolution, the adhesive applicator 32 also applies adhesive to the roll more than one revolution. This means that at least one adhesive applicator 32 has completed the adhesive application to the roll. At this point, the swing shaft 31 rotates counterclockwise, causing the adhesive applicator 32 to move away from the air shaft 2 and the roll, which are positioned opposite it.

[0031] More preferably, the roll waterproof packaging device, particularly the tape supply mechanism 3, also includes a telescopic cylinder 34. The telescopic cylinder 34 is fixedly connected to the main frame 1, and its output end is movably connected to a swing shaft 31. For example, the swing shaft 31 is provided with a support arm extending radially therefrom, the output end of the telescopic cylinder 34 is connected to the support arm, and the two are pivotable relative to each other. Thus, the linear motion of the telescopic cylinder 34 is converted into the rotation of the swing shaft 31, that is, the extension motion of the telescopic cylinder 34 is converted into the clockwise rotation of the swing shaft 31 (from the perspective of the first direction X shown in the figure), and the retraction motion of the telescopic cylinder 34 is converted into the counterclockwise rotation of the swing shaft 31, thereby driving the adhesive applicator 32 to approach or move away from the air shaft 2 and the roll on it.

[0032] Preferably, the controller is communicatively connected to the telescopic cylinder 34. While at least one nozzle 4 blows air, the air shaft 2 continues to rotate. The controller controls the output end of the telescopic cylinder 34 to extend, and the adhesive applicator 32 and the adhesive roller 33 approach the air shaft 2 and the roll on it to apply adhesive and press it onto the rotating roll until the adhesive tape has been applied for more than one revolution, that is, the adhesive applicator 32 has completed the adhesive application and packaging of the roll.

[0033] Preferably, the roll waterproofing packaging device further includes a roll supply mechanism that conveys the roll to be packaged to the air shaft 2. The roll supply mechanism conveys the roll to be packaged at a specific conveying speed, allowing the roll conveyed by the roll supply mechanism to pass over the air shaft 2. The roll waterproofing packaging device also includes a guide (not shown) that guides the roll conveyed from the roll supply mechanism to wind onto the air shaft 2 so as to ultimately wind it into a spool shape.

[0034] Preferably, the roll waterproof packaging device further includes an actuating element 5, which can be formed as a fork or other similar component. The actuating element 5 has a recess 51, the inner diameter of which is larger than the diameter of the air shaft 2, so that the air shaft 2 can pass through. The actuating element 5 is movable in the first direction X. After the roll is glued and packaged by the adhesive applicator 32 and the adhesive roller 33, the actuating element 5 moves towards the free end of the air shaft 2 in the first direction X. Since the inner diameter of the recess 51 is larger than the diameter of the air shaft 2 but smaller than the outer diameter of the roll, the actuating element 5 contacts the end surface of the roll, and the roll moves towards the free end of the air shaft 2 together with the actuating element 5. It is conceivable that at this time, the air shaft 2 is controlled by the controller to deflate in order to release the roll. It is also conceivable that the linear movement of the actuating element 5 is also controlled by the aforementioned controller.

[0035] More preferably, the roll waterproof packaging device also includes a plurality of driven rollers 6. The plurality of driven rollers 6 are disposed at the free end of the air expansion shaft 2 and are located below the air expansion shaft 2 in the height direction. Starting from the first driven roller 6, the plurality of driven rollers 6 are arranged at intervals from each other, gradually moving away from the main frame 1 along the first direction X. When the actuating member 5 removes the roll from the air expansion shaft 2, the roll falls onto the conveying channel formed by the plurality of driven rollers 6, and with the cooperation of the actuating member 5 and the driven rollers 6, the roll is conveyed along the first direction X to the next process execution equipment.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
