Description

Technical Field

[0001] The invention relates to the technical field of anti-counterfeiting composite film production, and in particular to a glue coating device for producing laser anti-counterfeiting composite films. Background Art

[0002] Laser anti-counterfeiting composite film is a material processed with special laser technology. It is usually composed of multiple layers of films with different functions. It has unique optical effects and anti-counterfeiting characteristics that are difficult to replicate. It is widely used in commodity packaging, labels, bills and other fields to enhance the anti-counterfeiting ability and aesthetics of the product. Gluing is carried out during the production process to effectively bond different material layers together to ensure the overall stability of the composite film. At the same time, gluing can also improve the sealing and waterproofness between materials and ensure the clarity and durability of the laser pattern. In addition, appropriate gluing technology can improve production efficiency, reduce defective product rates, and meet the requirements of composite films in different application scenarios.

[0003] During the gluing process of the anti-counterfeiting composite film, the uncoated film on the unloading roller is usually pulled by the rotation of the winding roller, and the friction between the film and the gluing roller causes the gluing roller to rotate to complete the gluing. However, this mechanism causes the initial section of the film between the unloading roller and the winding roller to be unable to be glued because the gluing roller does not rotate in time, and the gluing is gradually realized until the winding roller starts to operate, which will cause waste of this part of the film. In order to reduce this waste, shortening the distance between the winding roller and the unloading roller is an intuitive method, but this will compress the drying space of the film after gluing and affect the curing effect of the glue; while using a high-power fan to accelerate drying, the glue after coating will be unevenly distributed due to the strong wind force, thus affecting the quality of the finished product. If the distance between the winding roller and the unloading roller is increased to ensure that the film has enough time to dry, the waste of uncoated film will be aggravated.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figure 1-8As shown, the present invention is a glue coating equipment for the production of laser anti-counterfeiting laser composite film, including a box body 1 and a feed roller 2 and a winding roller 3 installed in the box body 1, and a processing mechanism 5 for gluing and drying a film body 4 is arranged in the box body 1; the processing mechanism 5 includes a glue storage box 51, a linkage glue coating mechanism 52, a guide roller assembly 53 and a drying mechanism 54, the glue storage box 51 is installed on the lower surface of the inside of the box body 1, the linkage glue coating mechanism 52 is connected with the feed roller 2 and extends into the glue storage box 51, and the linkage glue coating mechanism 52 is used for synchronously gluing the film body 4 when the feed roller 2 feeds, the guide roller assembly 53 and the drying mechanism 54 are both installed in the box body 1, the film body 4 after gluing bypasses the guide roller assembly 53 and is wound around the winding roller 3, and the drying mechanism 54 is used for drying the film body 4 bypassing the guide roller assembly 53.

[0021] It should be noted that, when in use, the uncoated film body 4 on the unloading roller 2 is bypassed by the linkage coating mechanism 52, and when the film body 4 is pulled to discharge, the linkage coating mechanism 52 will promptly and synchronously coat the glue in the glue storage box 51 evenly on the pulled film body 4, so that the initial film body 4 discharged from the unloading roller 2 can be coated with glue in time, and the glue coating process can be achieved without the need for the winding roller 3 to rotate, thereby avoiding the waste problem caused by the initial film body 4 not being coated with glue; The film body 4 after being coated with glue is passed around the guide roller assembly 53 and then wound around the winding roller 3. The guide roller assembly 53 is used to greatly extend the movement path of the film body 4 between the unwinding roller 2 and the winding roller 3, so that the film body 4 can be fully dried. The drying mechanism 54 is used to perform corresponding drying treatment on the film body 4 that has passed around the guide roller assembly 53, so that the film body 4 can have sufficient drying time, thereby improving the drying effect after coating with glue, which is beneficial to ensuring the quality of the finished product of the anti-counterfeiting composite film.

[0022] like Figure 1-2 As shown, a box door 6 is installed on one side of the box body 1 through a hinge, and a glue replenishing box 7 is provided on the side of the box body 1 away from the box door 6. A connecting pipe 8 with a valve is installed between the glue replenishing box 7 and the glue storage box 51, and a feed port 9 and a liquid level viewing port 10 are respectively provided on the top and side wall of the glue replenishing box 7.

[0023] It should be noted that when the glue in the glue storage box 51 needs to be replenished, the glue stored in the glue replenishment box 7 can be replenished into the glue storage box 51 in time by opening the valve on the connecting pipe 8, so as to avoid the situation that the glue coating is interrupted due to insufficient glue in the glue storage box 51. The glue stock in the glue replenishment box 7 can be conveniently checked in real time by using the liquid level viewport 10, and the glue can be added into the glue replenishment box 7 by opening the feed port 9, so as to ensure that there is always enough glue in the glue replenishment box 7. In addition, a liquid level sensor for detecting the glue liquid level is installed on the inner wall of the glue storage box 51 near the top, and cooperates with an external controller, so that when the glue in the glue storage box 51 is insufficient, the valve on the connecting pipe 8 can be automatically controlled to open for automatic glue replenishment.

[0024] like Figure 3-4 As shown, the linked glue coating mechanism 52 includes an upper rotating roller 521, a lower rotating roller 522, a glue coating belt 523 and a linkage member 524. The lower rotating roller 522 is rotatably installed on the inner wall of the glue storage box 51 near the bottom end, the upper rotating roller 521 is located above the lower rotating roller 522, the glue coating belt 523 is jointly connected with the upper rotating roller 521 and the lower rotating roller 522, and the linkage member 524 is installed between the upper rotating roller 521 and the discharge roller 2.

[0025] It should be noted that the film body 4 on the discharge roller 2 is passed around the top of the coating tape 523 and then pulled downward at an angle. During the pulling process, the film body 4 is always kept in contact with the top of the coating tape 523. Since pulling the film body 4 will drive the discharge roller 2 to rotate to discharge the material, the upper rotating roller 521 is driven to rotate synchronously through the linkage 524 when the discharge roller 2 rotates. When the upper rotating roller 521 rotates, it can drive the coating tape 523 to move, thereby facilitating the continuous driving of the coating tape 523 to dip into the glue in the glue storage box 51, thereby achieving continuous and uniform coating of the film body 4.

[0026] like Figure 3-4 As shown, the linkage 524 includes a first mounting shaft 5241, a first rotating shaft 5242, a sprocket 5243 and a chain 5244. The discharge roller 2 and the upper rotating roller 521 are rotatably connected to the inner wall of the box body 1 through the first mounting shaft 5241 and the first rotating shaft 5242 respectively. The two sprockets 5243 are respectively mounted on the first mounting shaft 5241 and the first rotating shaft 5242, and the chain 5244 is jointly connected with the two sprockets 5243.

[0027] It should be noted that the two sprockets 5243 are coaxially fixedly connected to the first installation shaft 5241 and the first rotating shaft 5242 respectively, so that the discharge roller 2 can synchronously drive the first installation shaft 5241 to rotate when discharging materials, and cooperate with the transmission of the sprocket 5243 and the chain 5244 to synchronously drive the upper rotating roller 521 connected to the first rotating shaft 5242 to rotate.

[0028] like Figure 3 and Figure 7As shown, the guide roller assembly 53 includes a first guide roller 531, a second guide roller 532, a third guide roller 533, a fourth guide roller 534, a fifth guide roller 535 and a second rotating shaft 536. The first guide roller 531, the second guide roller 532, the third guide roller 533, the fourth guide roller 534 and the fifth guide roller 535 are all rotatably connected to the inner wall of the box body 1 through the second rotating shaft 536. The present application does not limit the number of the first guide roller 531, the second guide roller 532, the third guide roller 533, the fourth guide roller 534 and the fifth guide roller 535. The following only provides a specific number of For reference, the two first guide rollers 531 are arranged near the bottom end of the box body 1, the two second guide rollers 532 are arranged near the top end of the box body 1, the two third guide rollers 533 and the two fourth guide rollers 534 are located between the two first guide rollers 531 and the two second guide rollers 532, and the fifth guide roller 535 is located between the two third guide rollers 533 and the two fourth guide rollers 534, and the film body 4 on the unwinding roller 2 is wound around the upper turning roller 521, the first guide roller 531, the second guide roller 532, the third guide roller 533, the fourth guide roller 534 and the fifth guide roller 535 in sequence.

[0029] It should be noted that the guide roller assembly 53 is not limited to including the first guide roller 531, the second guide roller 532, the third guide roller 533, the fourth guide roller 534, the fifth guide roller 535 and the second rotating shaft 536. The number of guide rollers can be adaptively adjusted according to the actual drying time required and the internal space of the box body 1. In this embodiment, after the film body 4 passes around the guide roller assembly 53, the glue-coated side thereof will not have any contact with the first guide roller 531, the second guide roller 532, the third guide roller 533, the fourth guide roller 534 and the fifth guide roller 535, thereby not only ensuring that the evenly coated glue will not be damaged, but also greatly extending the movement path of the film body 4, thereby facilitating sufficient drying of the film body 4.

[0030] like Figure 1 and Figure 3-4 As shown, the side wall of the box body 1 is rotatably connected to the second mounting shaft 11 for mounting the winding roller 3, and the unwinding roller 2 and the winding roller 3 are detachably connected to the first mounting shaft 5241 and the second mounting shaft 11 respectively. The present application does not limit the mounting structure and mounting method of the unwinding roller 2 and the winding roller 3. The disassembly and assembly of the unwinding roller 2 and the winding roller 3 are mature existing technologies and will not be elaborated herein. A motor 12 for driving the second mounting shaft 11 to rotate is installed on the outer side wall of the box body 1.

[0031] It should be noted that the use of the first mounting shaft 5241 and the second mounting shaft 11 facilitates the disassembly and assembly of the unloading roller 2 and the winding roller 3 as needed, so that the unloading roller 2 can be replaced after the unloading is completed, and it is also convenient for the winding roller 3 to be disassembled after winding a sufficient amount of the film body 4. When the pulled out initial section of the film body 4 is finally wound onto the winding roller 3, the subsequent unloading roller 2 does not need to be pulled. It only needs to start the motor 12 to drive the winding roller 3 to rotate, and then the film body 4 can be pulled to make the unloading roller 2 rotate adaptively to discharge the material.

[0032] like Figure 3 and Figure 8 As shown, the drying mechanism 54 includes a hot air pipe 541, a hot air nozzle 542, and a U-shaped portion 543, a first L-shaped portion 544, a second L-shaped portion 545 and a third L-shaped portion 546 which are connected in sequence. Several hot air nozzles 542 are evenly distributed on the U-shaped portion 543, the first L-shaped portion 544, the second L-shaped portion 545 and the third L-shaped portion 546 on one side close to the membrane body 4, and one end of the hot air pipe 541 is connected to the top of the U-shaped portion 543.

[0033] It should be noted that the U-shaped portion 543, the first L-shaped portion 544, the second L-shaped portion 545 and the third L-shaped portion 546 are all internal hollow structures, wherein the end of the U-shaped portion 543 away from the first L-shaped portion 544 is a closed structure, and the end of the third L-shaped portion 546 away from the second L-shaped portion 545 is also a closed structure. An external hot air device is used to transport the hot air to the hot air pipe 541, and finally a plurality of hot air nozzles 542 blow the hot air to the side of the film body 4 coated with glue. Since the film body 4 of the present application has a longer drying path and the glue-coated side of the film body 4 can be fully in contact with the hot air, a low-flow hot air can be used. The low-flow hot air blown to the glue-coated side of the film body 4 is not easy to blow the glue to flow, which is beneficial to improving the uniformity of glue coating.

[0034] like Figure 3 As shown, a rubber scraper 13 corresponding to the film body 4 is installed between the inner walls of the rubber storage box 51 near the top, and a rubber guide groove with two ends open is formed on the upper surface of the rubber scraper 13, and the notch of the rubber guide groove contacts the film body 4.

[0035] It should be noted that the scraper board 13 is made of soft material and is not easy to cause damage to the film body 4. The scraper board 13 is used to conveniently scrape off the excess glue coated on the film body 4. In this embodiment, the scraper board 13 is arranged at an angle, and the end away from the film body 4 is the lower end. The excess glue scraped off can return to the glue storage box 51 along the glue guide groove to avoid wasting glue.

[0036] like Figure 5-6 and Figure 8As shown, the drying mechanism 54 further includes a supporting slide plate 547 and a convex plate 548. The two supporting slide plates 547 are symmetrically mounted on the lower surface of the U-shaped portion 543, and the convex plate 548 is mounted on the side wall of the first L-shaped portion 544. The lower surface of the interior of the box body 1 is provided with a slide groove (such as Figure 3 As shown), a cylinder 15 connected to the convex plate 548 is installed on the inner wall of the box body 1, and one end of the hot air pipe 541 away from the U-shaped portion 543 slides through the side wall of the box body 1 and extends outward.

[0037] It should be noted that when the drying mechanism 54 dries the film body 4 that has passed through the guide roller assembly 53 (eg Figure 6 As shown), at this time, the U-shaped portion 543, the first L-shaped portion 544, the second L-shaped portion 545 and the third L-shaped portion 546 are distributed around the path of the film body 4, so that the glue-coated side of the film body 4 can fully contact the hot air and improve the drying effect. If the drying mechanism 54 is a fixed structure, it will hinder the installation of the film body 4 because the film body 4 needs to bypass the guide roller assembly 53 when installing; In order to facilitate the installation of the membrane body 4, the cylinder 15 is used to conveniently drive the drying mechanism 54 to move forward and backward, and during the movement, the supporting slide plate 547 is driven to slide adaptively along the slide groove. In this embodiment, the hot air pipe 541 is a "7"-shaped structure, and the hot air pipe 541 is slidingly connected to the side wall of the box body 1 to ensure that the hot air pipe 541 will not affect the movement of the drying mechanism 54. In addition, the hot air pipe 541 is connected to an external hot air device through a hose or a deformable telescopic tube.

[0038] like Figure 3 As shown, the scraper plate 13 is rotatably connected to the inner wall of the glue storage box 51 through a pin shaft, and a knob 14 for locking the pin shaft is installed on the outer side of the glue storage box 51.

[0039] It should be noted that the pin shaft can be used to conveniently adjust the inclination angle of the scraper plate 13 as needed. Adjusting the position of the scraper plate 13 can not only adjust the tension of the film body 4, but also facilitate the adjustment of the scraping degree of the scraper plate 13, thereby controlling the glue coating thickness of the film body 4. After adjusting the appropriate angle, the pin shaft is locked and positioned using the knob 14 to ensure the position stability of the scraper plate 13.

[0040] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
