Description

Technical Field

[0001] This utility model relates to the field of cigarette equipment technology, and in particular to a glue applicator transmission mechanism and a glue applicator. Background Technology

[0002] Packaging machines are used to produce small cigarette packs. During the production process, a certain amount of white glue needs to be applied to the fixed parts of the label paper at specific times and points using a glue applicator. This ensures that the label paper can be firmly attached according to the process requirements after subsequent folding, forming a firmly attached and square qualified small cigarette pack.

[0003] When the glue applicator rotates to apply glue, the label paper also moves; the glue application is achieved through the coordinated movement of both. When the packaging machine changes auxiliary materials or for other reasons, the initial circumferential position of the glue applicator may change. During glue application, even if the movement speeds of both the label paper and the glue applicator remain constant, the position of the glue dots applied to the label paper will change, leading to defects such as poor adhesion of small cigarette packs. Therefore, it is necessary to adjust the circumferential position of the glue applicator before applying glue.

[0004] In related technologies, the glue applicator includes a transmission assembly and a mounting base. The transmission assembly includes a drive shaft, gears, and a key. The mounting base is used to mount the adhesive sheet, and the mounting base and gears are connected to the drive shaft via the same key. When adjusting the circumferential position of the mounting base, because the mounting base and gears are connected to the drive shaft via the same key, it is necessary to remove the transmission housing protective plate, turn off the oil pump, rotate the gear, and then adjust the position of the mounting base. The adjustment process is cumbersome, wastes manpower, increases maintenance time, and also affects the effective operating rate of the glue applicator. Utility Model Content

[0005] The purpose of this utility model is to provide a glue applicator transmission mechanism and glue applicator, which eliminates the need to disassemble the transmission box protective plate, turn off the oil pump and rotate the gear when adjusting the circumferential position of the mounting base. This makes adjustment convenient, saves manpower, reduces maintenance time and improves the effective working rate of the glue applicator.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] On the one hand, a glue applicator transmission mechanism is provided, comprising:

[0008] The drive shaft is provided with an annular groove;

[0009] A gear, which is fitted onto and fixed to the drive shaft;

[0010] An adjusting assembly includes at least two adjusting members, which are sequentially arranged around the annular groove. The adjusting members are in contact with the bottom wall of the annular groove and can rotate about the axis of the drive shaft along the bottom wall of the annular groove. A first fixing assembly is detachably connected between two adjacent adjusting members. The first fixing assembly can make the adjusting members abut against the bottom wall of the annular groove. One of the adjusting members is provided with a positioning protrusion for inserting into the slot of the mounting base along the axial direction of the drive shaft.

[0011] In some possible implementations, there are two adjustment members, both of which are semi-annular structures.

[0012] In some possible implementations, the two ends of the adjusting member are respectively attached to the two sidewalls of the annular groove.

[0013] In some possible implementations, the drive shaft is provided with an annular protrusion, and the gear is located on one side of the annular protrusion along the axial direction and fixed to the annular protrusion.

[0014] In some possible implementations, one end of the adjustment member is abutted against the sidewall of the annular protrusion on the other side along the axial direction.

[0015] In some possible implementations, the positioning protrusion is provided with an indicator arrow, and the annular protrusion is provided with a plurality of scale lines along the circumference, the indicator arrow being alignable with one of the scale lines.

[0016] In some possible implementations, the annular protrusion has a first fixing hole, the gear has a second fixing hole, and the glue applicator transmission mechanism further includes a second fixing component, which passes through the first fixing hole and the second fixing hole to connect the gear and the annular protrusion.

[0017] In some possible implementations, of two adjacent adjusting members, one adjusting member has a first through hole at both ends, and the other adjusting member has a second through hole at both ends. The first fixing component passes through the first through hole and the second through hole to connect the two adjusting members.

[0018] In some possible implementations, the first fixing component includes a bolt and a nut, the bolt passing through the first through hole and the second through hole and being threadedly connected to the nut.

[0019] On the other hand, an adhesive applicator is provided, including a mounting base and an adhesive applicator transmission mechanism as described in any of the above embodiments, wherein the mounting base is provided with a slot, and the positioning protrusion is inserted into the slot along the axial direction of the transmission shaft.

[0020] The beneficial effects of this utility model are:

[0021] The adhesive applicator transmission mechanism provided by this utility model includes a transmission shaft, gears, and adjusting components. When adjusting the circumferential position of the mounting base, the first fixing component disengages all adjusting parts from the bottom wall of the annular groove. Then, all adjusting parts are rotated to adjust the circumferential position of the positioning protrusion. Afterward, the first fixing component presses the adjusting parts against the bottom wall of the annular groove, thus fixing all adjusting parts. Finally, the mounting base is rotated to align its slot with the positioning protrusion, and the mounting base is inserted into the positioning protrusion through the slot. The gear is fitted and fixed to the transmission shaft. When adjusting the circumferential position of the mounting base, the circumferential position of the mounting base is adjusted by adjusting the circumferential position of the positioning protrusion. This eliminates the need to disassemble the transmission housing protective plate, shut down the oil pump, and rotate the gears, making adjustment convenient, saving manpower, reducing maintenance time, and improving the effective operating rate of the adhesive applicator. Furthermore, the first fixing component and the two adjusting parts can be disassembled from the transmission shaft, facilitating disassembly and assembly. Attached Figure Description

[0036] like Figures 1 to 5As shown, this utility model provides a glue applicator transmission mechanism, including a transmission shaft 1, a gear 2, and an adjustment assembly. The transmission shaft 1 is provided with an annular groove 11, and the gear 2 is sleeved and fixed to the transmission shaft 1. The adjustment assembly includes at least two adjusting members 3, which are sequentially arranged around the annular groove 11. The adjusting members 3 are in contact with the bottom wall of the annular groove 11 and can rotate about the axis of the transmission shaft 1 along the bottom wall of the annular groove 11. A first fixing assembly is detachably connected between two adjacent adjusting members 3. The first fixing assembly can make the adjusting members 3 press against the bottom wall of the annular groove 11. One of the adjusting members 3 is provided with a positioning protrusion 31, which is used to insert into the slot 101 of the mounting base 100 along the axial direction of the transmission shaft 1. Specifically, the bottom wall of the annular groove 11 is a cylindrical surface. This design guides the rotation of the adjusting member 3 and facilitates the processing of the annular groove 11. In other embodiments, the bottom wall of the annular groove 11 can be partially fitted with the inner wall of the adjusting member 3 to guide the rotation of the adjusting member 3. This embodiment is not the only one that can guide the rotation of the adjusting member 3.

[0037] When adjusting the circumferential position of the mounting base 100, the first fixing component disengages all the adjusting parts 3 from the bottom wall of the annular groove 11. Then, all the adjusting parts 3 are rotated to adjust the circumferential position of the positioning protrusion 31. Afterward, the first fixing component is used to press the adjusting parts 3 against the bottom wall of the annular groove 11 to fix all the adjusting parts 3. Finally, the mounting base 100 is rotated so that the slot 101 of the mounting base 100 is aligned with the positioning protrusion 31, and the mounting base 100 is inserted into the positioning protrusion 31 through the slot 101. The gear 2 is sleeved and fixed to the transmission shaft 1. When adjusting the circumferential position of the mounting base 100, the circumferential position of the positioning protrusion 31 is changed by rotating the adjusting parts 3, thus adjusting the circumferential position of the mounting base 100. It is not necessary to disassemble the transmission housing protective plate, turn off the oil pump, and rotate the gear 2. The adjustment is convenient, saves manpower, reduces maintenance time, and improves the effective working rate of the glue applicator. In addition, the first fixing component and the two adjusting parts 3 can be disassembled from the transmission shaft 1, which is convenient for disassembly and assembly.

[0038] Optionally, in this embodiment, in two adjacent adjusting members 3, one adjusting member 3 has a first through hole 32 at both ends, and the other adjusting member 3 has a second through hole 33 at both ends.

To facilitate disassembly and achieve a reliable connection, optionally, in this embodiment, the first fixing component includes a bolt and a nut. The bolt passes through the first through hole 32 and the second through hole 33 and is threadedly connected to the nut. Specifically, when adjusting the circumferential position of the mounting base 100, the bolt and nut are loosened without causing the two adjusting members 3 to separate. Then, the adjusting member 3 is rotated to adjust the circumferential position of the positioning protrusion 31. Afterward, the bolt and nut are tightened to fix the adjusting member 3. Finally, the mounting base 100 is rotated so that the slot 101 of the mounting base 100 is aligned with the positioning protrusion 31, and the mounting base 100 is inserted into the positioning protrusion 31 through the slot 101. In other embodiments, the first fixing component includes a locking post and a buckle, the locking post passing through a first through hole 32 and a second through hole 33 and engaging with the buckle.

[0039] To save adjustment time and cost, optionally, in this embodiment, there are two adjusting members 3, both of which are semi-annular structures. In other embodiments, there are three or more adjusting members 3, which can achieve adjustment of the circumferential position of the positioning protrusion 31. In addition, the adjusting members 3 can be irregular structures, as long as all the adjusting members 3 can be closed to form a circular structure.

[0040] Optionally, in this embodiment, the two ends of the adjusting member 3 are respectively fitted to the two sidewalls of the annular groove 11. With this configuration, the two sidewalls of the annular groove 11 can restrict the axial position of the adjusting member 3, ensuring the accuracy of the axial position of the adjusting member 3 during installation.

Alternatively, one of the first fixing hole 121 and the second fixing hole is an internally threaded hole, and the other is a smooth hole. The second fixing component includes a screw. The screw passes through the smooth hole and is threadedly connected to the internally threaded hole.

[0045] In addition, in order to make the fixation more secure and ensure the reliable transmission of gear 2, at least two first fixing holes 121 are provided. At least two first fixing holes 121 are equally spaced along the circumference of the annular protrusion 12, and the second fixing holes are provided in a one-to-one correspondence with the first fixing holes 121.

[0046] This utility model also provides a glue applicator, including a mounting base 100 and a glue applicator transmission mechanism. The mounting base 100 is provided with a slot 101 for mounting an adhesive sheet 200. A positioning protrusion 31 is inserted into the slot 101 along the axial direction of the transmission shaft 1. This glue applicator is easy to adjust when adjusting the circumferential position of the mounting base 100, saving manpower, reducing maintenance time, and improving the effective working rate of the glue applicator.
