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] During the production of small cigarette packs, 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 adhered according to the process requirements after subsequent folding, forming a firmly adhered and square qualified small cigarette pack.

[0003] The glue applicator includes a drive shaft, a base, and a mounting base. The mounting base is used to mount the glue applicator sheet. The base is connected to the drive shaft, and the mounting base is fitted over the base. A setter screw passes through the side wall of the mounting base and presses against the outer wall of the base. During operation, the drive shaft drives the base to rotate, and the base's rotation drives the mounting base to rotate. Because the connection between the mounting base and the base is a clearance fit, the setter screw needs to be tightened to ensure accurate glue application on the glue applicator sheet during high-speed operation. Over-tightening may deform the base, preventing the drive shaft from being installed within it; under-tightening may cause the mounting base to shift during high-speed operation, resulting in incorrect glue application on the label paper. Therefore, the tightening force of the setter screw on the base is difficult to control, hindering stable and effective transmission to the mounting base. Furthermore, the setter screw can damage the outer wall of the mounting base, requiring periodic replacement and increasing spare parts costs.

[0004] Furthermore, when adjusting the axial position of the mounting base on the base, the tightening screw needs to be loosened, the position of the mounting base adjusted, and then the tightening screw tightened again. This manual adjustment of the distance cannot guarantee the accuracy of the adjusted position. If the desired position is not achieved, the machine needs to be stopped and readjusted, which is time-consuming and affects work efficiency. Therefore, there is an urgent need for a glue applicator transmission structure and a glue applicator to solve the above technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a glue applicator transmission structure and glue applicator, which can achieve stable and effective transmission to the mounting base without damaging the outer wall of the base, reducing the consumption of spare parts. In addition, when adjusting the axial position of the mounting base on the base, the accuracy of the adjustment position is improved, the adjustment is convenient and the adjustment time is short, and it will not affect the work efficiency.

[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] The base has an external thread structure on its outer wall, and at least two positioning grooves are recessed inward on the outer surface of the external thread structure, with the positioning grooves extending along the axial direction of the base.

[0009] A drive shaft is used to drive the base to rotate;

[0010] Mounting base for mounting the first adhesive sheet, the inner wall of the mounting base is provided with at least two protrusions, the at least two protrusions are provided in a one-to-one correspondence with at least two positioning grooves, and the protrusions and the positioning grooves are inserted into the axial direction of the base;

[0011] An adjusting element is threadedly connected to the external thread structure, at least one of the adjusting elements is located on one side of the mounting base along the axial direction, and at least one of the adjusting elements is located on the other side of the mounting base along the axial direction.

[0012] In some possible implementations, all of the positioning slots are evenly spaced along the circumference of the base.

[0013] In some possible implementations, the adjusting member is a polygonal structure with an internal threaded hole, and the external threaded structure is threadedly connected to the internal threaded hole.

[0014] In some possible implementations, the adhesive applicator drive structure further includes a mounting base for mounting a second adhesive applicator sheet, and the drive shaft can drive the mounting base to rotate.

[0015] In some possible implementations, the base is fixed to one end of the fixing seat.

[0016] In some possible implementations, the adhesive applicator drive structure further includes a positioning component disposed between the drive shaft and the fixed seat, for limiting the axial position of the fixed seat on the drive shaft.

[0017] In some possible implementations, one of the fixed base and the drive shaft is provided with a circumferential groove, and the other is provided with a mounting groove. One end of the positioning component elastically abuts against the bottom of the circumferential groove and is slidably connected to the circumferential groove, while the other end of the positioning component is fixed in the mounting groove.

[0018] In some possible implementations, the positioning component includes an elastic element and a ball bearing, one end of the elastic element being fixed to the bottom of the mounting groove, and the ball bearing being fixed to the other end of the elastic element. The ball bearing extends into the circumferential groove and abuts against and slides against the groove wall of the circumferential groove.

[0019] In some possible implementations, the circumferential groove is an annular groove.

[0020] On the other hand, an adhesive applicator is provided, including a first applicator sheet and an applicator transmission structure as described in any of the above embodiments, wherein the first applicator sheet is mounted on the mounting base.

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

[0022] The adhesive applicator transmission structure provided by this utility model includes a base, a transmission shaft, a mounting base, and adjusting components. The mounting base is circumferentially fixed through the engagement of at least two positioning grooves and at least two protrusions. The mounting base is clamped and fixed to the base by the clamping force of the adjusting components on both sides, achieving axial fixation. When the base rotates, it drives the mounting base to rotate, achieving stable and effective transmission without damaging the outer wall of the base, thus reducing the cost of spare parts. To adjust the axial position of the mounting base on the base, first rotate the adjusting component on one side of the mounting base to change its position, then move the mounting base. Finally, rotate the adjusting component on the other side of the mounting base until it contacts the mounting base, facilitating easy adjustment of the mounting base's position. The adjustment time is short and does not affect work efficiency. The positioning grooves guide the movement of the mounting base. Furthermore, because the adjusting component is threaded to an external thread structure, its position on the base is fixed after one rotation, thus improving the accuracy of the adjustment position.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0033] like Figures 1 to 3 As shown, this utility model provides a glue applicator transmission structure, including a base 1, a drive shaft, a mounting base 2, and an adjusting member 3. The outer wall of the base 1 is provided with an external thread structure 11. At least two positioning grooves 12 are recessed inward on the outer surface of the external thread structure 11, extending axially along the base 1. The drive shaft drives the base 1 to rotate. The mounting base 2 is used to mount a first glue applicator sheet 100. When the mounting base 2 rotates, the first glue applicator sheet 100 can apply glue to the bottom of the label paper. The inner wall of the mounting base 2 is provided with at least two protrusions 21, each corresponding to one of the positioning grooves 12, and the protrusions 21 and positioning grooves 12 are inserted into each other along the axial direction of the base 1. The adjusting member 3 is threadedly connected to the external thread structure 11. At least one adjusting member 3 is located on one side of the mounting base 2 along the axial direction, and at least one adjusting member 3 is located on the other side of the mounting base 2 along the axial direction. In this embodiment, two adjusting members 3 are provided, located on opposite sides of the mounting base 2 along the axial direction. This setup is simple and cost-effective.

[0034] The mounting base 2 can be circumferentially fixed by the cooperation of at least two positioning grooves 12 and at least two protrusions 21. The mounting base 2 is clamped and fixed to the base 1 by the clamping force of the adjusting parts 3 on both sides, thus achieving axial fixation of the mounting base 2. When the base 1 rotates, the base 1 can drive the mounting base 2 to rotate, achieving stable and effective transmission of the mounting base 2 without damaging the outer wall of the base 1, reducing the consumption of spare parts. When adjusting the axial position of the mounting base 2 on the base 1, first rotate the adjusting part 3 on one side of the mounting base 2 to change the position of the adjusting part 3, then move the mounting base 2 to contact the adjusting part 3, and then rotate the adjusting part 3 on the other side of the mounting base 2 to contact the mounting base 2. This facilitates the adjustment of the position of the mounting base 2, and the adjustment time is short, which does not affect the work efficiency. The positioning grooves 12 play a guiding role in the movement of the mounting base 2. Furthermore, since the adjusting member 3 is threadedly connected to the external thread structure 11, the position of the adjusting member 3 on the base 1 is fixed when the adjusting member 3 rotates one revolution, thus improving the accuracy of the adjustment position.

[0035] Optionally, all positioning slots 12 are evenly spaced along the circumference of the base 1. This arrangement makes the structure of the base 1 resemble a spline, resulting in higher centering accuracy and more uniform force distribution on the mounting base 2 during transmission. In this embodiment, there are six positioning slots 12.

[0036] To facilitate rotation of the adjusting component 3 by the operator, the adjusting component 3 may optionally be a polygonal structure with an internal threaded hole, and the external threaded structure 11 is threadedly connected to the internal threaded hole. Specifically, the adjusting component 3 is a regular hexagonal structure. In other embodiments, the adjusting component 3 may be circular, other regular or irregular structures, as long as it allows rotation of the adjusting component 3, and is not limited to this embodiment. In addition, the outer wall of the adjusting component 3 may be provided with a concave-convex structure to increase friction.

[0037] Optionally, in this embodiment, the glue applicator transmission structure further includes a fixed base 4, which is used to mount the second glue applicator 200. The transmission shaft can drive the fixed base 4 to rotate. When the fixed base 4 rotates, the second glue applicator 200 can apply glue to the side of the label paper. By driving the same transmission shaft, glue can be applied to the side and bottom of the label paper simultaneously, improving the glue application efficiency. Optionally, in this embodiment, the base 1 is fixed to one end of the fixed base 4. Since the base 1 is fixed to one end of the fixed base 4, the transmission shaft can drive one of the base 1 and the fixed base 4 to rotate while also driving the other to rotate, simplifying the transmission structure. Specifically, the fixed base 4 and the base 1 are integrated. This arrangement facilitates processing.

[0038] Optionally, the mounting base 2 is configured to be detachably connected to the first adhesive sheet 100, and the fixing base 4 is configured to be detachably connected to the second adhesive sheet 200. To ensure a secure connection, in this embodiment, the first adhesive sheet 100 is fixed to the mounting base 2 by screws, and the second adhesive sheet 200 is fixed to the fixing base 4 by screws. Furthermore, the first adhesive sheet 100 can be welded or bonded to the mounting base 2, and the second adhesive sheet 200 can be welded or bonded to the fixing base 4.

[0039] Optionally, the adhesive applicator transmission structure also includes a positioning component, which is disposed between the transmission shaft and the fixed seat 4 to limit the axial position of the fixed seat 4 on the transmission shaft. This arrangement prevents the fixed seat 4 from sliding axially relative to the transmission shaft during rotation, ensuring transmission stability and preventing the adhesive application position from shifting.

[0040] Optionally, one of the fixed base 4 and the drive shaft is provided with a circumferential groove 41, and the other is provided with a mounting groove. One end of the positioning component elastically abuts against the bottom of the circumferential groove 41 and is slidably connected to the circumferential groove 41, while the other end of the positioning component is fixed in the mounting groove. That is, the fixed base 4 is provided with a circumferential groove 41, and the drive shaft is provided with a mounting groove; or, the fixed base 4 is provided with a mounting groove, and the drive shaft is provided with a circumferential groove 41. When the drive shaft extends into the fixed base 4, the positioning component can be fully pressed into the mounting groove. When the drive shaft extends to the designated installation position, one end of the positioning component can extend into the circumferential groove 41 and elastically abut against the bottom of the circumferential groove 41 to achieve axial limiting. This configuration facilitates the installation of the drive shaft into the fixed base 4 and makes operation convenient.

[0041] Furthermore, the circumferential groove 41 is an annular groove, meaning that the circumferential groove 41 extends 360 degrees circumferentially along the inner wall of the fixed base 4. This configuration allows the drive shaft to rotate relative to the fixed base 4 after it is installed inside the fixed base 4, with other components then restricting the circumferential position of the fixed base 4. In other embodiments, the arc of the circumferential groove 41 extending circumferentially along the inner wall of the fixed base 4 may be less than 360 degrees.

[0042] In this embodiment, the fixed base 4 is provided with a circumferential groove 41, and the drive shaft is provided with a mounting groove. Specifically, the fixed base 4 includes a base body 42 and a sleeve 43. The sleeve 43 is detachably connected to the base body 42, and the inner wall of the sleeve 43 is provided with a circumferential groove 41. This arrangement facilitates the disassembly, assembly, and processing of the fixed base 4.

[0043] Optionally, in this embodiment, the positioning component includes an elastic element and a ball bearing. One end of the elastic element is fixed to the bottom of the mounting groove, and the ball bearing is fixed to the other end of the elastic element. The ball bearing extends into the circumferential groove 41 and abuts against and slides against the wall of the circumferential groove 41. This configuration is relatively simple and can achieve axial positioning. In other embodiments, the positioning component includes an elastic element and a semi-circular block. One end of the elastic element is fixed to the bottom of the mounting groove, and the flat end of the semi-circular block is fixed to one end of the elastic element. The semi-circular block extends into the circumferential groove 41 and abuts against and slides against the wall of the circumferential groove 41.

[0044] This utility model also provides an adhesive applicator, including a first adhesive applicator sheet 100 and an adhesive applicator transmission structure, wherein the first adhesive applicator sheet 100 is mounted on the mounting base 2. This adhesive applicator can achieve stable and effective transmission to the mounting base 2 without damaging the outer wall of the base 1, reducing the cost of spare parts. Furthermore, when adjusting the axial position of the mounting base 2 on the base 1, it improves the accuracy of the adjustment position, facilitates adjustment, and reduces adjustment time, without affecting work efficiency.

[0045] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
