Description

Technical Field

[0001] This utility model relates to the field of cigarette equipment technology, and in particular to a glue applicator transmission structure 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 structure and a glue applicator sheet. The transmission structure includes a drive shaft, a rotating base, gears, and a key. The rotating base and gears are connected to the drive shaft via the same key, and the glue applicator sheet is mounted on the rotating base. When adjusting the circumferential position of the rotating base, because the rotating 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 gears, and then adjust the position of the rotating 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 transmission structure and a glue applicator. When adjusting the circumferential position of the rotating seat, it is not necessary to disassemble the protective plate of the transmission box, turn off the oil pump and rotate the gear. The structure is relatively simple, easy to adjust, 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 drive structure is provided, comprising:

[0008] A drive shaft, wherein at least one positioning groove is recessed at the end face of the first end;

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

[0010] An adjustment assembly includes an adjustment member sleeved on the first end of the drive shaft. The inner wall of the adjustment member is provided with at least one positioning protrusion, and at least one positioning protrusion is provided in correspondence with at least one positioning groove. The positioning protrusion and the positioning groove are inserted into the drive shaft along the axial direction.

[0011] A rotating seat is sleeved on the transmission shaft. The rotating seat is adjustable in position along the circumferential direction of the adjusting member. The rotating seat is used to connect the upper film.

[0012] In some possible implementations, the adjusting assembly further includes a first fixing member, the adjusting member having an arc-shaped hole extending circumferentially along the adjusting member, the rotating seat having a connecting hole, the first fixing member passing through the arc-shaped hole and being threadedly connected to the connecting hole, and the first fixing member being slidable within the arc-shaped hole.

[0013] In some possible implementations, the inner wall of the rotating seat is attached to the outer wall of the drive shaft, and the rotating seat can rotate along the outer wall of the drive shaft.

[0014] In some possible implementations, at least two arc-shaped holes are provided, and the at least two arc-shaped holes are equally spaced along the circumference of the adjusting member, and the connecting holes are provided in a one-to-one correspondence with the arc-shaped holes.

[0015] In some possible implementations, the adjusting member includes a large-diameter portion and a small-diameter portion connected in sequence, wherein the outer diameter of the large-diameter portion is larger than the outer diameter of the small-diameter portion, and the large-diameter portion is provided with the arc-shaped hole.

[0016] In some possible implementations, a guide groove is provided at the opening of the end face of the positioning groove near the first end of the drive shaft.

[0017] 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.

[0018] In some possible implementations, the annular protrusion has a first fixing hole, the gear has a second fixing hole, and the adhesive applicator transmission structure further includes a fixing component that connects the first fixing hole and the second fixing hole to fix the gear to the annular protrusion.

[0019] In some possible implementations, the fixing assembly includes a bolt and a nut, the bolt passing through the first fixing hole and the second fixing hole and being threadedly connected to the nut.

[0020] On the other hand, an adhesive applicator is provided, including an adhesive sheet and an adhesive applicator transmission structure as described in any of the above embodiments, wherein the adhesive sheet is connected to the rotating base.

[0021] The beneficial effects of this utility model are:

[0022] The adhesive applicator transmission structure provided by this utility model includes a transmission shaft, gears, an adjusting component, and a rotating seat. The adjusting component is fitted onto the first end of the transmission shaft. The circumferential position of the adjusting component on the transmission shaft is limited by the interlocking of a positioning protrusion and a positioning groove. Based on this, the circumferential position of the rotating seat relative to the adjusting component is adjusted, thus achieving adjustment of the circumferential position of the rotating seat. Furthermore, since the gear is fitted onto and fixed to the transmission shaft, the gear and the rotating seat do not interfere with each other. When adjusting the circumferential position of the rotating seat, it is not necessary to disassemble the transmission housing protective plate, turn off the oil pump, and rotate the gear, making adjustment convenient, saving manpower, reducing maintenance time, and improving the effective operating rate of the adhesive applicator. In addition, a positioning groove is recessed at the end face of the first end of the transmission shaft, allowing the adjusting component to be inserted from the end face of the first end of the transmission shaft and fitted onto the first end of the transmission shaft, facilitating the installation and removal of the adjusting component. The structure of the adjusting component is relatively simple, making the overall structure also relatively simple. Attached Figure Description

[0033] like Figures 1 to 4 As shown, this utility model provides a transmission structure for an adhesive applicator, including a transmission shaft 1, a gear 2, an adjustment component, and a rotating seat 4. The transmission shaft 1 has at least one positioning groove 11 recessed at its first end face. The gear 2 is sleeved and fixed to the transmission shaft 1. The adjustment component includes an adjustment member 3, which is sleeved at the first end of the transmission shaft 1. The inner wall of the adjustment member 3 has at least one positioning protrusion 31, which corresponds to at least one positioning groove 11. The positioning protrusion 31 and the positioning groove 11 are inserted into each other along the axial direction of the transmission shaft 1. The rotating seat 4 is sleeved on the transmission shaft 1 and is adjustable along the circumferential direction of the adjustment member 3. The rotating seat 4 is used to connect the upper film 100.

[0034] Adjusting component 3 is fitted onto the first end of drive shaft 1. The circumferential position of adjusting component 3 on drive shaft 1 is restricted by the insertion and engagement of positioning protrusion 31 and positioning groove 11. Based on this, the circumferential position of rotating seat 4 relative to adjusting component 3 is adjusted, thereby achieving adjustment of the circumferential position of rotating seat 4. Furthermore, since gear 2 is fitted onto and fixed to drive shaft 1, gear 2 and rotating seat 4 do not interfere with each other. When adjusting the circumferential position of rotating seat 4, it is not necessary to disassemble the transmission housing protective plate, turn off the oil pump, and rotate gear 2. Adjustment is convenient, saves manpower, reduces maintenance time, and improves the effective working rate of the glue applicator. In addition, a positioning groove 11 is recessed at the end face of the first end of drive shaft 1. Adjusting component 3 is inserted from the end face of the first end of drive shaft 1 and fitted onto the first end of drive shaft 1, facilitating the installation and removal of adjusting component 3. Moreover, the structure of adjusting component 3 is relatively simple, making the overall structure relatively simple as well.

[0035] During transmission, the drive shaft 1 transmits power to the adjusting member 3, causing the adjusting member 3 to rotate. Since the rotating seat 4 is fixed to the adjusting member 3, the rotating seat 4 can rotate. In this embodiment, two positioning protrusions 31 are provided, and the two positioning protrusions 31 are equally spaced along the circumference of the adjusting member 3. The positioning grooves 11 are correspondingly arranged one-to-one with the positioning protrusions 31. This arrangement facilitates processing and improves the transmission effect between the drive shaft 1 and the adjusting member 3.

[0036] Optionally, in this embodiment, the adjusting assembly further includes a first fixing member 5. The adjusting member 3 has an arc-shaped hole 32 extending circumferentially along the adjusting member 3. The rotating seat 4 has a connecting hole 41. The first fixing member 5 passes through the arc-shaped hole 32 and is threadedly connected to the connecting hole 41, and the first fixing member 5 can slide within the arc-shaped hole 32. When adjusting the circumferential position of the rotating seat 4, the first fixing member 5 is loosened, but it does not disengage from the connecting hole 41. Then, the rotating seat 4 is rotated. During the rotation of the rotating seat 4, the first fixing member 5 slides within the arc-shaped hole 32, guiding the rotation of the rotating seat 4. After the rotating seat 4 is adjusted to the desired position, the first fixing member 5 is tightened to fix the rotating seat 4 to the adjusting member 3. In addition, the arc-shaped hole 32 can also limit the rotation limit position of the rotating seat 4.

[0037] Optionally, the first fixing member 5 can be a screw or bolt, which is readily available and saves costs. Furthermore, in this embodiment, the adjusting assembly also includes a shim, which is disposed between the first fixing member 5 and the adjusting member 3. This arrangement makes the connection more secure and prevents the screw or bolt from damaging the surface of the adjusting member 3.

[0038] Optionally, in this embodiment, the inner wall of the rotating seat 4 is attached to the outer wall of the transmission shaft 1, and the rotating seat 4 can rotate along the outer wall of the transmission shaft 1. With this configuration, when the first fixing member 5 is loosened and the rotating seat 4 is rotated, the outer wall of the transmission shaft 1 plays a further guiding role in the rotation of the rotating seat 4.

[0039] In order to achieve a reliable connection between the adjusting member 3 and the rotating seat 4, optionally, in this embodiment, at least two arc-shaped holes 32 are provided, and at least two arc-shaped holes 32 are provided at equal intervals along the circumference of the adjusting member 3, and the connecting hole 41 is provided in a one-to-one correspondence with the arc-shaped holes 32.

[0040] Optionally, in this embodiment, as Figure 3 As shown, the adjusting member 3 includes a large-diameter portion 33 and a small-diameter portion 34 connected in sequence. The outer diameter of the large-diameter portion 33 is larger than the outer diameter of the small-diameter portion 34, and the large-diameter portion 33 is provided with an arc-shaped hole 32. This arrangement facilitates the processing of the adjusting member 3. In addition, when the first fixing member 5 is installed on the adjusting member 3, the circumferential peripheral space of the small-diameter portion 34 serves as the installation and operation space for the first fixing member 5, making installation more convenient.

[0041] In other embodiments, the adjustment assembly further includes multiple second fixing members. One of the adjusting member 3 and the rotating seat 4 has multiple first adjusting holes along its circumference, and the other has multiple second adjusting holes along its circumference. The second fixing members selectively connect one of the first adjusting holes and one of the second adjusting holes to fix the rotating seat 4 to the adjusting member 3. With the above arrangement, the circumferential position of the rotating seat 4 along the adjusting member 3 can also be adjusted.

[0042] Optionally, in this embodiment, a guide groove 111 is provided at the opening of the positioning groove 11 near the end face of the first end of the drive shaft 1. This arrangement facilitates the insertion of the positioning protrusion 31 of the adjusting member 3 into the positioning groove 11 of the drive shaft 1. Specifically, the width of the guide groove 111 gradually decreases axially inward from the end face of the first end of the drive shaft 1.

[0043] Optionally, in this embodiment, the drive shaft 1 is provided with an annular protrusion 12, and the gear 2 is located on one side of the annular protrusion 12 along the axial direction and fixed to the annular protrusion 12. The annular protrusion 12 facilitates the installation and fixation of the gear 2. Further, the annular protrusion 12 is provided with a first fixing hole 121, and the gear 2 is provided with a second fixing hole. The adhesive applicator transmission structure also includes a fixing component, which connects the first fixing hole 121 and the second fixing hole to fix the gear 2 to the annular protrusion 12. This arrangement facilitates the connection between the gear 2 and the annular protrusion 12. Optionally, the fixing component includes a bolt and a nut, with the bolt passing through the first fixing hole 121 and the second fixing hole and threadedly connected to the nut for easy disassembly and reliable connection; or, the fixing component includes a locking post and a snap-fit, with the locking post passing through the first fixing hole 121 and the second fixing hole and engaging with the snap-fit.

[0044] This utility model also provides a glue applicator, including an upper glue sheet 100 and a glue applicator transmission structure, wherein the upper glue sheet 100 is connected to the rotating seat 4. When adjusting the circumferential position of the rotating seat 4, this glue applicator does not require disassembling the transmission box protective plate, turning off the oil pump and rotating the gear 2. The structure is relatively simple, the adjustment is convenient, it saves manpower, reduces maintenance time, and improves the effective working rate of the glue applicator.
