Description

Technical Field

[0001] This utility model relates to the field of roll material production technology, specifically to an automatic double-sided tape application mechanism. Background Technology

[0002] In the subsequent processing and packaging of roll materials such as paper tape, protective film, and labels, it is often necessary to apply double-sided tape to the ends or specific locations of the material rolls to secure the finished rolls and prevent them from loosening during storage and transportation. Traditional processes generally employ manual methods for applying the tape, which involves first measuring the material length, manually cutting the double-sided tape, and then attaching it to the end of the material roll. This method is not only inefficient and makes it difficult to guarantee the accuracy of the application position and length, but also has high labor costs and low production efficiency, making it unsuitable for the fast-paced and continuous production rhythm of modern manufacturing. Therefore, developing a fully automated mechanism that can be highly integrated with slitting and rewinding production lines to achieve precise positioning and automatic application of double-sided tape is of great significance for improving the packaging quality of end products, increasing production efficiency, and reducing labor costs.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4This utility model provides a technical solution: an automatic double-sided tape applicator, including an unwinding mechanism 1 and a main unit 4. The main unit 4 is equipped with an tape applicator 5, which includes a mounting frame 51 fixed on the main unit 4. A drive mechanism 52 is mounted on the mounting frame 51. The drive mechanism 52 is connected to a movable frame 53 so that the movable frame 53 can move left and right. A double-sided tape roll 54 driven by a motor is mounted on the movable frame 53. A release film roll 55 driven by a motor is also mounted on the movable frame 53. A polyurethane transition roller 6 is also connected to the main unit 4 by a bearing.

[0017] A roll material 2 is installed on the unwinding mechanism 1, and a web guiding machine 3 is provided behind the unwinding mechanism 1, and the web guiding machine 3 is provided in front of the main unit 4; an air knife assembly 7 is installed on the main unit 4, and the air knife assembly 7 is provided behind the adhesive application mechanism 5, and a slitting mechanism 8 is provided behind the air knife assembly 7 and installed on the main unit 4, while a winding mechanism 9 is provided behind the slitting mechanism 8 and installed on the main unit 4. When using this automatic double-sided tape applicator, such as Figures 1-4 As shown, the unwinding mechanism 1 can release the material on the roll 2, and the air knife group 7 can cut the released wide material into multiple narrow materials. The winding mechanism 9 can then wind up the cut narrow materials. When the material is wound to a preset length, the slitting mechanism 8 can cut the material (the unwinding mechanism 1, air knife group 7, slitting mechanism 8 and winding mechanism 9 are all existing devices, and their working principles will not be described in detail). The drive mechanism 52 consists of a motor, a drive gear, a toothed belt, and a driven gear. The motor is fixed on the mounting frame 51, and the drive gear is fixed to the output end of the motor. The drive gear is connected to the driven gear via the toothed belt, and the driven gear is connected to the mounting frame 51 by a bearing. The toothed belt is fixed to the movable frame 53. A slider 531 is fixed on the movable frame 53, and the slider 531 is slidably connected to the guide rail 532, which is fixed to the mounting frame 51. The double-sided adhesive roll 54 includes a double-sided adhesive body 541 and a release film body 542, and the release film body 542 is connected to the release film roll 55. A rotatable swing frame 56 is connected to the movable frame 53, and the swing frame 56 is connected to the adjustment... The output end of the throttle cylinder 561 is rotatably connected, and the other end of the adjusting cylinder 561 is rotatably connected to the movable frame 53. The swing frame 56 is also connected to the guide roller 562 by a bearing, and the guide roller 562 contacts the double-sided adhesive body 541 and the release film body 542 to achieve guidance. The swing frame 56 is also fixed with a pressure roller 563, which contacts the double-sided adhesive body 541 and is located directly above the polyurethane transition roller 6. The swing frame 56 is also fixed with a rotary cylinder 57, and a bracket 571 is fixed on the turntable of the rotary cylinder 57. A cutter 572 is fixed on the bracket 571, and the central axis of the turntable of the rotary cylinder 57 coincides with the central axis of the pressure roller 563. During the use of the device, such as Figures 1-4 As shown, when the material on the roll 2 is released to the preset length (this length can be measured by a meter counter to ensure the accuracy of the length), the extension of the control cylinder 561 is controlled, thereby driving the swing frame 56 to swing under force, so that the double-sided adhesive body 541 below the pressure roller 563 contacts the material above the polyurethane transition roller 6 to achieve the bonding effect. Moreover, through the squeezing and cooperation between the pressure roller 563 and the polyurethane transition roller 6, the stability of the bonding between the double-sided adhesive body 541 and the material can be guaranteed. When the material is bonded to the double-sided adhesive body 541, the movable frame 53 can be moved by the drive mechanism 52. With the sliding guide between the slider 531 and the guide rail 532, the stability of the movement of the movable frame 53 can be ensured. The movement of the movable frame 53 can drive the double-sided adhesive body 541 to move. With the motor driving the double-sided adhesive roll 54, the double-sided adhesive body 541 can be released. With the release film body 542, the release film body 542 on the double-sided adhesive body 541 can be wound up, thereby separating the release film body 542 from the double-sided adhesive body 541. Then, the double-sided adhesive body 541 can be moved by the movable frame 53 to be bonded to the material surface laterally. After the double-sided adhesive body 541 is bonded, the rotating cylinder 57 drives the bracket 571 and the cutter 572 on the turntable to rotate. The cutter 572 can cut the double-sided adhesive body 541, thereby completing the bonding of the double-sided adhesive body 541 laterally on the wide material. After the double-sided adhesive body 541 is attached, the air knife assembly 7 can cut the double-sided adhesive body 541 and the material into strips. After the double-sided adhesive body 541 and the material strips are cut, when the double-sided adhesive body 541 and the material move to the rear of the slitting mechanism 8, the slitting mechanism 8 can achieve the transverse cutting of the material. That is, at this time, the end of the narrow material being wound on the winding mechanism 9 is attached with the double-sided adhesive body 541. When the narrow material being wound on the winding mechanism 9 comes into contact with the double-sided adhesive body 541, the double-sided adhesive body 541 can be attached to the material to fix the material roll, preventing the wound material from becoming loose after unloading. (To ensure the normal operation of the device, an industrial camera can be installed at the cutting position of the slitting mechanism 8 to identify the position of the double-sided adhesive body 541 and ensure the accuracy of the cutting position of the slitting mechanism 8), thereby ensuring the normal operation of the device.
