Description

Technical Field

[0001] This utility model relates to the field of auxiliary tooling technology for cigarette packaging machines, and in particular to a quantitative gluing device for YB25 trademark paper. Background Technology

[0002] Currently, the YB25 flexible box packaging machine uses roller contact gluing for the label paper, such as... Figure 1 As shown, the adhesive application process is as follows: the adhesive is placed in the glue cylinder 7, and the adhesive is picked up from the glue cylinder 7 by a rotating glue roller 5. The glue roller 5 is equipped with a scraper 6 to control the thickness of the adhesive on the glue roller 5. Finally, the glue applicator 1 contacts the glue roller 5, and the glue applicator sheet installed on the glue applicator 1 scrapes a certain amount of adhesive from the glue roller 5 and applies it to the packaging material.

[0003] In actual production, the above-mentioned glue application scheme requires disassembly and cleaning of the glue cylinder assembly before the start of each day's production shift. After cleaning, the amount of glue applied needs to be adjusted. The traditional glue application gap requires manual measurement using a feeler gauge, repeatedly loosening screws and moving the glue sheet, which takes about 10 minutes per time. Moreover, it relies on operating experience and has low precision. This makes it impossible to quantify the amount of glue, and it is all based on experience, which undoubtedly affects the consistency of the bonding effect. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a quantitative gluing device for YB25 trademark paper, which solves the problem that the amount of glue cannot be quantified in the existing technology, and that the operation is based entirely on experience, which affects the consistency of the bonding effect.

[0005] This utility model solves the above-mentioned technical problems through the following technical means: a YB25 trademark paper quantitative gluing device, including a gluing roller and a gluing sheet, wherein the gluing roller is provided with an adjustment cavity opened along the axial direction, the inner wall of the adjustment cavity is provided with a guide through hole that penetrates the radial direction of the gluing roller, and the two sides of the gluing roller extend along the guide through hole to form a base, and a gluing sheet holder is slidably inserted into the base, and the gluing sheet is detachably connected to the gluing sheet holder; The guide through hole is rotatably connected to a worm gear shaft with a fixed worm gear in the middle. The two ends of the worm gear shaft are provided with external threads with opposite directions of rotation. The film holder is provided with threaded holes that are adapted to the external threads. The adjustment cavity is rotatably connected to a worm for driving the worm wheel shaft. The worm meshes with the worm wheel to drive the upper film to move synchronously along the direction of the guide hole.

[0006] Optionally, the adjustment cavity is located on the non-axial line of the coating roller.

[0007] Optionally, one end of the worm gear is used to connect to the output end of the servo motor.

[0008] Optionally, one end of the worm gear is connected to a handwheel, the handwheel is provided with a marking pointer, and the end face of the glue-applying roller is provided with scale lines corresponding to the outer edge of the handwheel.

[0009] Optionally, each scale line corresponds to a specific displacement of the upper film.

[0010] Optionally, the handwheel is provided with a positioning hole, and a plurality of pin holes are evenly distributed on the end face of the glue-applying roller along the rotation trajectory of the positioning hole. The positioning hole and the pin holes are used to insert positioning pins to fix the handwheel.

[0011] The beneficial effects of this utility model are: This invention features an adjustment cavity and guide hole on the coating roller. A handwheel drives a worm gear to rotate, which meshes with a worm wheel shaft with a fixed worm wheel in the middle. The worm wheel shaft has external threads with opposite directions at both ends, and the film holder has threaded holes that match the external threads. Since the slider of the film holder slides into a groove on the base, the base can only slide relative to the worm wheel shaft, thus converting the rotation of the worm wheel shaft into linear movement of the film holder. This drives the upper film to move synchronously along the guide hole, thereby simultaneously adjusting the coating gap on both sides and adjusting the amount of coating. Compared with the traditional method of manually measuring with feeler gauges and adjusting the upper film on both sides separately, this invention greatly saves adjustment time, improves efficiency, and achieves quantitative and visual adjustment while ensuring the accuracy of the adjustment.

For those skilled in the art, the specific meaning of the above-mentioned terms can be understood according to the specific circumstances.

[0016] like Figures 1-4 As shown, this utility model discloses a quantitative gluing device for YB25 trademark paper, including a gluing roller 1 and a gluing sheet 21. The gluing roller 1 has an adjustment cavity 11 opened along the axial direction. The inner wall of the adjustment cavity 11 has a guide hole 12 that penetrates the radial direction of the gluing roller 1. The two sides of the gluing roller 1 extend along the direction of the guide hole 12 to form a base 13. A film holder 22 is slidably inserted into the base 13. The film sheet 21 and the film holder 22 are detachably connected, such as by a threaded connection. The base 13 has two rectangular blind holes. The film holder 22 is provided with two corresponding sliders. The ends of the sliders are provided with anti-drop protrusions. The sliders of the film holder 22 are slidably inserted into the grooves on the base 13.

[0017] In this embodiment, a worm gear shaft 14 with a fixed worm gear in the middle is rotatably connected inside the guide through hole 12. The two ends of the worm gear shaft 14 are provided with external threads with opposite directions of rotation. The film holder 22 is provided with a threaded hole that is adapted to and meshes with the external threads. The adjusting cavity 11 is rotatably connected with a worm 15 for driving the worm gear shaft 14. The worm 15 meshes with the worm gear. Since the film holder 22 is slidably inserted into the base 13, it cannot rotate but forms a threaded pair to move, thereby driving the upper film 21 to move synchronously along the direction of the guide through hole 12, thereby realizing the adjustment of the distance between the upper film 21 and the upper glue roller 5.

[0018] In this embodiment, to avoid interfering with the drive connection of the coating roller 1, the adjustment cavity 11 is located on the non-axial line of the coating roller 1. This arrangement provides space for the worm gear 15 to mesh with the worm wheel.

[0019] In this embodiment, one end of the worm gear 15 is connected to a handwheel 31, and a marking pointer 32 is provided on the handwheel 31. A scale line 33 is provided on the end face of the glue roller 1 corresponding to the outer edge of the handwheel 31, and each scale line 33 corresponds to a specific displacement of the film 21.

[0020] In some other embodiments, the handwheel 31 may be provided with positioning holes, and a number of pin holes are evenly distributed on the end face of the glue roller 1 along the rotation trajectory of the positioning holes. The positioning holes and pin holes are used to insert positioning pins to fix the handwheel 31.

[0021] The working principle of this utility model is as follows: In use, the adhesive application device of this utility model allows for synchronous fine-tuning of the adhesive sheet 21 by rotating the handwheel 31. Since each scale line 33 corresponds to a specific displacement of the adhesive sheet 21, the movement distance of the adhesive sheet 21 can be determined by the number of rotations of the scale line 33. Specifically, rotating the handwheel 31 drives the worm gear 15 to rotate. The worm gear 15 meshes with the worm wheel, and the worm wheel shaft 14, which is fixed in the middle, has external threads with opposite directions at both ends. The adhesive sheet holder 22 has threaded holes that match the external threads. Since the slider of the adhesive sheet holder 22 is slidably inserted into the groove on the base 13, the base 13 can only slide relative to the slider, thus converting the rotation of the worm wheel shaft 14 into linear movement of the base 13. This drives the adhesive sheet 21 to move synchronously along the guide hole 12, simultaneously adjusting the adhesive application gap.

[0022] Compared to the traditional method of manually measuring the amount of adhesive applied using feeler gauges and adjusting the adhesive sheets 21 on both sides separately, this invention significantly saves adjustment time and improves efficiency. It also quantifies the adjustment and ensures accuracy. Furthermore, due to the reversible self-locking characteristic of the worm gear drive, the worm shaft 14 cannot drive the worm 15 to rotate, thus ensuring the stability of the adhesive sheet 21 under stress.

[0023] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model. Technologies, shapes, and structural parts not described in detail in this utility model are all known technologies.
