Description

Technical Field

[0001] The present invention relates to the technical field of gluing devices, in particular to a gluing device. Background Art

[0002] The gluing mechanism is a crucial component of the tipping machine, used to apply glue to the tipping paper. The gluing mechanism primarily consists of a gluing roller, a gluing control roller, and a glue cylinder. The glue cylinder contains liquid glue, and the gluing control roller dips into the liquid glue in the cylinder and transfers it to the gluing roller, which then applies the glue to the tipping paper. Therefore, the thickness of the glue on the tipping paper is directly affected by the gluing mechanism. Excessive glue thickness can lead to problems like leaks and overflows during tipping. A thinner glue thickness can result in loose bonds, leading to inadequate glue thickness. Therefore, an inappropriate glue thickness directly impacts the quality of cigarette tipping.

[0003] The gap between the gluing roller and the gluing control roller in the existing gluing mechanism cannot be adjusted, resulting in the inability to adjust the thickness of the glue liquid outside the gluing roller online, thereby affecting the quality of cigarette connection.

[0041] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0042] In order to solve the above technical problems, the embodiment of the present invention discloses a gluing device, such as Figure 1 As shown, a glue cylinder 1 is provided on it, and an opening is provided on the top of the glue cylinder 1. The glue liquid is contained in the glue cylinder 1. Specifically, a card slot 31 is provided at the bottom of the glue cylinder 1. Figure 2 As shown, the gluing device further includes a mounting frame 32, on which a protrusion 33 is provided. The protrusion 33 is inserted into the card slot 31 to fix the glue cylinder 1, and the card connection is arranged to facilitate the disassembly of the glue cylinder 1. Figure 2 As shown, the gluing device includes: a gluing roller 2, a gluing control roller 3, a transmission device 4, and an adjustment mechanism 5. The gluing roller 2 is disposed within the gluing cylinder 1, with both ends of the gluing roller 2 rotatably connected to the gluing cylinder 1. The gluing control roller 3 is also disposed within the gluing cylinder 1, and has a groove (not shown) on its circumferential surface that carries the glue. The gluing control roller 3 is rotatably connected to the gluing cylinder 1 at both ends. The axis of the gluing control roller 3 is parallel to the axis of the gluing roller 2, and a first gap is defined between the circumferential surfaces of the gluing control roller 3 and the gluing roller 2, through which the glue passes. The transmission device 4 is disposed between the gluing roller 2 and the gluing control roller 3. When the gluing roller 2 rotates, the transmission device 4 drives the gluing control roller 3 to rotate. The adjustment mechanism 5 is disposed on the gluing control roller 3 and is used to adjust the distance between the gluing control roller 3 and the gluing roller 2 to adjust the width of the first gap, thereby adjusting the thickness of the glue applied to the gluing roller 2.

[0043] By adopting the above technical solution, the adjustment mechanism 5 is set to adjust the distance between the control glue roller 3 and the upper glue roller 2 to adjust the width of the first gap, thereby adjusting the thickness of the glue liquid on the upper glue roller 2 to meet the requirements of cigarette connection, thereby improving the quality of cigarette connection.

[0044] According to another specific embodiment of the present invention, Figure 3As shown, the gluing device further includes a first roller 6 and a second roller 7. The gluing roller 2 is mounted on the first roller 6, and the gluing control roller 3 is mounted on the second roller 7. The gluing device also includes a motor 30, the output end of which is connected to the first roller 6. The motor 30 is used to drive the first roller 6 to rotate. The transmission device includes a first gear 8 and a second gear 9. The first gear 8 is mounted on the first roller 6. The second gear 9 is mounted on the second roller 7. Specifically, there are two first gears 8 and two second gears 9, each of which is located at either end of the first roller 6. The two second gears 9 are located at either end of the gluing control roller 3. The two second gears 9 mesh with the two first gears 8, respectively.

[0045] When in use, the motor 30 is started to drive the first roller 6 to rotate, and the upper glue roller 2 and the first gear 8 on the first roller 6 rotate together with the first roller 6. When the first gear 8 rotates, it drives the second roller 7 to rotate by engaging with the second gear 9, and the control glue roller 3 on the second roller 7 rotates. The circumferential surface and groove of the control glue roller 3 can dip the glue in the glue cylinder 1 and transfer the glue to the circumferential surface of the upper glue roller 2, and then the upper glue roller 2 connects the butt paper.

[0046] According to another specific embodiment of the present invention, Figure 1 As shown, it also includes two mounting holes 10, the two mounting holes 10 are along the axial direction of the control rubber roller 3 (as shown in FIG. Figure 1 (shown in the X direction) are symmetrically arranged on the side wall of the glue cylinder 1, as shown in FIG. Figure 3 and Figure 4 As shown, the adjustment mechanism includes two mounting seats 11, which are detachably connected to the glue cylinder 1. A round platform 12 is provided on the mounting seat 11. The round platforms 12 on the two mounting seats 11 are respectively inserted into the two mounting holes 10. A connecting hole 13 is provided on the round platform 12. The axis of the connecting hole 13 is spaced a certain distance from the axis of the round platform 12 (such as Figure 4 As shown in FIG. 1 , both ends of the second roller shaft 7 are respectively inserted into the two connecting holes 13 and can rotate in the connecting holes 13 . Figure 4 Where L2 is the distance between the axis of the first roller 6 and the axis of the second roller 7. Figure 4 , the distance between the axis of the first roller 6 and the axis of the second roller 7 is the smallest. At this time, the first gap between the circumferential surfaces of the upper glue roller 2 and the control glue roller 3 is the smallest, and the thickness of the glue on the upper glue roller 2 is small. When the mounting seat 11 rotates from Figure 4When rotating counterclockwise from the position shown in , the distance between the axis of the first roller 6 and the axis of the second roller 7 gradually increases. At this time, the first gap between the circumferential surfaces of the upper glue roller 2 and the control glue roller 3 increases, and the thickness of the glue on the upper glue roller 2 increases. In this application, the adjustment range of the first gap between the upper glue roller 2 and the control glue roller 3 is smaller than the matching clearance between the first gear 8 and the second gear 9. Therefore, when adjusting the first gap, the first gear 8 and the second gear 9 can always be engaged.

[0047] With the above technical solution, since the axis of the connecting hole 13 is spaced a certain distance from the axis of the table 12, that is, the connecting hole 13 and the table 12 are not concentric, when the mounting seat 11 rotates around the axis of the table 12, the two ends of the second roller 7 will move around the axis of the table 12 together with the connecting hole 13, thereby changing the distance between the axis of the control glue roller 3 and the axis of the upper glue roller 2, and then changing the width of the first gap, thereby achieving the effect of controlling the thickness of the glue.

[0048] According to another specific embodiment of the present invention, Figure 1 As shown, it also includes two threaded holes 14, which are symmetrically arranged on the side wall of the glue cylinder 1 along the axial direction of the glue control roller 3. Figure 2 and Figure 4 As shown, the mounting base 11 further includes an abutment portion 15, which is connected to the truncated cone 12. When the truncated cone 12 is inserted into the mounting hole 10, the abutment portion 15 is located on the outside of the glue cylinder 1. An arcuate groove 16 is provided on the abutment portion 15, and the axis of the arcuate groove 16 coincides with the axis of the truncated cone 12. The adjustment mechanism 5 further includes two bolts 17, which pass through the two arcuate grooves 16 respectively and are threadedly connected to the corresponding threaded holes 14 to fix the connecting base 13 on the glue cylinder 1.

[0049] When the width of the first gap needs to be adjusted, the two bolts 17 are loosened and the two mounting blocks 11 are simultaneously rotated in the same direction to change the distance between the axis of the control roller 3 and the axis of the upper roller 2. When the adjustment is completed, the two bolts 17 are correspondingly locked in the two threaded holes 14 to fix the mounting blocks 11 to the side wall of the glue tank 1. The provision of the arcuate slot 16 and the bolt connection facilitate adjustment of the mounting blocks 11.

[0050] According to another specific embodiment of the present invention, Figure 5 As shown, the gluing device also includes a scraper 18, located within the glue cylinder 1. Preferably, to improve wear resistance, the scraper 18 is made of metal. A working edge 19 is provided on the scraper 18, and a second gap is defined between the working edge 19 and the outer circumference of the glue control roller 3. Specifically, depending on the requirements of the piping process, the width of the second gap is 0.1-0.2 mm to ensure the thickness of the glue on the glue control roller 3.

[0051] According to another specific embodiment of the present invention, Figure 1 and Figure 5 As shown, the gluing device further includes: two first through-holes 20, a connecting shaft 21, and a locking mechanism 22. The two first through-holes 20 are symmetrically arranged on the side wall of the glue cylinder 1 along the axis of the glue control roller 3. The two ends of the connecting shaft 21 respectively pass through the two first through-holes 20 and extend outside the glue cylinder 1. The connecting shaft 21 can rotate within the first through-holes 20. The scraper 18 is disposed on the connecting shaft 21. The locking mechanism 22 is disposed on the glue cylinder 1 and is used to lock the connecting shaft 21 to prevent it from rotating.

[0052] According to another specific embodiment of the present invention, Figure 6 As shown, the locking mechanism includes a locking plate 23 and an external spline 26. The locking plate 23 is connected to the glue cylinder 1 and is provided with a locking hole 24, in which an internal spline 25 is provided. The external spline 26 is provided on the connecting shaft 21. The connecting shaft 21 can slide along its axial direction, so that the external spline 26 can be inserted into the internal spline 25 or disengaged from the internal spline 25. When the external spline 26 is disengaged from the internal spline 25, the connecting shaft 21 can rotate about its own axis. When the external spline 26 is inserted into the internal spline 25, the internal spline 25 restricts the connecting shaft 21 from rotating about its own axis.

[0053] When the second gap between the working edge 19 of the scraper plate 18 and the outer circumference of the control roller 3 is not appropriate, the connecting shaft 21 can be slid along its axial direction to disengage the outer spline 26 from the inner spline 25, and then the connecting shaft 21 is rotated to adjust the second gap between the working edge 19 and the outer circumference of the control roller 3 to an appropriate width, and then the connecting shaft 21 is slid in the opposite direction of its axial direction to insert the outer spline 26 into the inner spline 25 to lock the connecting shaft 21. The setting of the locking mechanism can prevent the connecting shaft 21 from rotating arbitrarily and affecting the scraping effect.

[0054] According to another specific embodiment of the present invention, Figure 6 As shown, the assembly further includes a protective cover 27 and an elastic member 29. The protective cover 27 is connected to the glue cylinder 1 and is provided with a second through-hole 28. One end of the connecting shaft 21 passes through the second through-hole 28 and protrudes from the exterior of the protective cover 27. The elastic member 29 is disposed between the inner wall of the protective cover 27 and the external spline 26. Specifically, the elastic member 29 is a compression spring that applies a force to the connecting shaft 21 toward the external spline 26, forcing the external spline 26 to insert into the internal spline 25. This prevents the external spline 26 from disengaging from the internal spline 25, which would otherwise affect the scraping effect.

[0055] Although the present invention has been illustrated and described with reference to certain preferred embodiments thereof, it should be understood by those skilled in the art that the above description is provided as a further detailed description of the present invention in conjunction with specific embodiments thereof, and that the specific implementation of the present invention is not limited to these descriptions. Those skilled in the art may make various changes in form and details, including simple deductions or substitutions, without departing from the spirit and scope of the present invention.
