Description

Technical Field

[0001] This utility model relates to the field of inner lining paper production technology, specifically to an adhesive device for inner lining paper production equipment. Background Technology

[0002] The inner packaging paper of cigarette packs is made of aluminum foil. Cigarette liner paper is used inside cigarette packs to effectively protect the cigarettes from moisture and preserve their aroma, and also helps to maintain the shape of the cigarette packaging. Types of cigarette liner paper mainly include composite liner paper, vacuum-metallized transfer paper, and aluminum-free liner paper. The bonding process of different liner papers directly affects their moisture-proof and aroma-preserving properties.

[0003] The inner lining paper needs to be bonded during processing, and this bonding process requires a bonding device. For example, Chinese patent application number 201921104768.8 discloses a bonding device for inner lining paper production equipment. This patent includes a conveyor belt, with driven rollers embedded on both sides of the horizontal end of the conveyor belt's inner cavity. Fixed plates are fitted onto both sides of the driven rollers. An applicator roller is located on one side of the top of the conveyor belt, and an adhesive roller is located on the other side. This patent uses a drive motor to rotate the adhesive roller via the drive roller and gear disc. During rotation, the gear disc moves a gear sleeve through its teeth. As the gear sleeve moves, the conveyor belt rotates synchronously, causing the two inner lining papers to move at different speeds. This structure, using a single drive motor to simultaneously operate the adhesive roller and the conveyor belt, reduces production costs while improving the synchronization between the adhesive roller and the conveyor belt, thus enhancing the bonding fit.

[0004] While the aforementioned patent reduces production costs and improves the synchronization of the bonding roller and conveyor belt, thus enhancing the adhesion, in practical use, it lacks a pre-cleaning mechanism for the inner liner paper. This means the inner liner paper may become contaminated with dust during transport. If the surface of the inner liner paper contains dust, oil, debris, or other impurities, it will hinder the adhesive from making full contact with the inner liner paper, resulting in uneven adhesive application and affecting the integrity and strength of the coating. Furthermore, surface impurities may mix into the adhesive during the coating process, affecting not only the adhesive's performance (such as reducing its viscosity and altering its drying time) but also potentially causing granular unevenness in the adhesive layer. This can negatively impact the bonding effect between the inner liner paper and other components, and may even adversely affect subsequent processing and product use, thereby reducing the production quality of the patent to some extent.

[0005] Therefore, it is necessary to modify the bonding device in the above patent to effectively prevent the inner lining paper from being adhered to by dust in the workshop during the transportation process, which would affect the performance of the adhesive and thus have an adverse impact on subsequent processing and product use.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 5 As shown, this utility model provides an adhesive device for inner liner paper production equipment, including a base 1, a support frame 2 fixedly connected to the top of the base 1, a detachable take-up roller 3 disposed inside the support frame 2, a gantry frame 4 fixedly connected to the top of the base 1, a vacuum cleaner 5 fixedly connected to the top of the gantry frame 4, a distributor 6 fixedly connected to the output end of the vacuum cleaner 5 extending to the inner wall of the gantry frame 4, a plurality of evenly arranged suction heads 7 fixedly connected to the input end of the distributor 6, a dust collection box 8 connected to the output end of the vacuum cleaner 5, and a bearing frame 9 symmetrically fixedly connected to the top of the base 1, with a bearing plate 10 fixedly connected to the top of the two bearing frames 9. The inner side of the frame 9 is provided with a lifting groove 11. A lead screw 12 is rotatably connected inside the lifting groove 11 on one side, and the top of the lead screw 12 is driven by a lifting motor. A lifting block 13 is threadedly connected to the surface of the lead screw 12. A slider 14 is slidably connected inside the lifting groove 11 on the other side. The lifting block 13 and the slider 14 are rotatably connected to the same rotating shaft 15, and the rotating shaft 15 is driven by a reduction motor. A glue-applying roller 16 is sleeved on the surface of the rotating shaft 15. A liquid storage tank 17 is fixedly connected to the top of the support plate 10. A glue pump 18 is fixedly connected inside the liquid storage tank 17, and the output end of the glue pump 18 extends above the glue-applying roller 16 and works in conjunction with it.

[0024] refer to Figure 1 and Figure 3The top of the base 1 is symmetrically fixedly connected to the gantry frame 4 with a fixing block 19. The surface of the fixing block 19 is provided with an adjustment groove 20. The inside of the adjustment groove 20 is slidably connected to an adjustment block 21. The top of the fixing block 19 is threadedly connected to an adjustment column 22, and the bottom of the adjustment column 22 is rotatably connected to the adjustment block 21. A guide roller 23 is fixedly connected between every two symmetrical adjustment blocks 21.

[0025] As a technical optimization of this utility model, by setting up the fixing block 19, adjusting groove 20, adjusting block 21, adjusting column 22 and guide roller 23, the position of adjusting block 21 in adjusting groove 20 can be adjusted by adjusting column 22 according to the conveying path and position requirements of the inner lining paper, thereby adjusting the height and angle of guide roller 23, realizing precise guidance of the inner lining paper, ensuring the stability and accuracy of the inner lining paper during the conveying process, and helping to improve the bonding accuracy.

[0026] refer to Figure 3 The adjusting groove 20 has symmetrically opened limiting grooves on its groove wall, and the adjusting block 21 has symmetrically fixedly connected to the limiting block 24, and the limiting block 24 is slidably connected to the limiting groove.

[0027] As a technical optimization of this utility model, by setting the limiting block 24 and the limiting groove, the movement direction of the adjusting block 21 in the adjusting groove 20 can be restricted, preventing the adjusting block 21 from shaking or deviating during the adjustment process, thereby improving the stability and reliability of the adjustment, and thus ensuring the accuracy of the guide roller 23 in guiding the inner lining paper.

[0028] refer to Figure 3 A buffer spring 25 is fitted on the surface of the adjusting column 22, and the buffer spring 25 is located above the adjusting block 21.

[0029] As a technical optimization of this utility model, by setting the buffer spring 25, when the inner liner paper generates a certain impact force or tension during the conveying process, the buffer spring 25 can play a buffering role, reducing damage to the guide roller 23 and the entire guide structure, and at the same time, it can also prevent the inner liner paper from tearing or deforming due to excessive impact force, thus protecting the inner liner paper and the equipment.

[0030] refer to Figure 4 and Figure 5 The top of the lifting block 13 and the slider 14 are fixedly connected to the same guide frame 26. The bottom of the guide frame 26 is provided with a guide port, which is located directly above the glue coating roller 16. The top of the guide frame 26 is fixedly connected to a diverter pipe 27, and the top of the diverter pipe 27 is connected to the output end of the glue pump 18 through a telescopic pipe. The bottom of the diverter pipe 27 is connected to several glue spraying heads. The surface of the glue coating roller 16 is covered with a uniform glue cotton.

[0031] As a technical optimization of this utility model, by setting up the flow guide 26, the diversion pipe 27 and the glue spraying head, the glue introduced from the output end of the glue pump 18 through the telescopic pipe of the diversion pipe 27 can be evenly sprayed onto the glue coating roller 16 through the glue spraying head, so as to achieve precise glue supply and distribution. Furthermore, by using the glue-equalizing cotton, the uniformity and stability of the glue coating on the inner lining paper can be further improved, thereby improving the bonding quality.

[0032] refer to Figure 1 and Figure 2 The dust collection box 8 has symmetrical pressure relief ports on both sides, and the inner wall of the pressure relief port is fixedly connected with a dust blocking net 28.

[0033] As a technical optimization of this utility model, the setting of the pressure relief port can balance the air pressure inside and outside the dust collection box 8, preventing the dust collection box 8 from being affected by excessively high or low air pressure or from being damaged. At the same time, the dust filter 28 can prevent dust from being discharged from the pressure relief port, avoiding secondary pollution to the working environment.

[0034] The working principle and usage process of this utility model are as follows: When using this adhesive device, the take-up roller 3 with the inner lining paper to be bonded is installed on the support frame 2, and one end of it is first guided and positioned by the guide roller 23. At this time, according to the thickness and material of the inner lining paper, the height of the lifting block 13 and the slider 14 is adjusted by driving the lead screw 12 to rotate through the lifting motor, thereby determining the appropriate distance and pressure between the glue coating roller 16 and the inner lining paper to ensure the uniformity and effect of glue coating. Then, the adjusting column 22 is rotated to make the adjusting block 21 move up and down in the adjusting groove 20. The height and position of the guide roller 23 are adjusted to ensure that the inner liner paper accurately passes through the glue-applying roller 16 and the take-up roller 3 during the conveying process. Simultaneously, the buffer spring 25 acts as a buffer and shock absorber, ensuring the stability of the inner liner paper conveying and allowing it to accurately enter the subsequent glue-applying and bonding area. It is then connected to the external traction device. When applying glue to the inner liner paper, the external traction device is activated to pull the inner liner paper, and the glue pump 18 is activated to extract the glue from the storage tank 17. The glue enters the diversion pipe 27 through the telescopic pipe. The design ensures that the glue delivery is unobstructed during the lifting and lowering of the coating roller 16. The diverter pipe 27 evenly distributes the glue to multiple spray nozzles, which spray the glue onto the guide frame 26. The glue then flows through the guide port at the bottom of the guide frame 26 to the glue distribution cotton on the coating roller 16 for absorption. Next, the geared motor is started, driving the rotating shaft 15 and the coating roller 16 to rotate. During the rotation of the coating roller 16, the glue that has flowed onto the surface of the glue distribution cotton is evenly applied to the inner lining paper. During the glue application process, the vacuum cleaner 5 is started, generating suction to... The suction head 7 sucks in dust and impurities from the area around the adhesive application zone. These dust and impurities are then transported to the dust collection box 8 via the distributor 6. The pressure relief vents and dust filter 28 on both sides of the dust collection box 8 balance the air pressure and prevent dust leakage, ensuring the stability of the suction process and the cleanliness of the working environment. This prevents dust and other impurities from affecting the adhesive bonding effect, thus solving the problem that the inner lining paper may be adhered to by dust in the workshop during the transportation process, which would affect the performance of the adhesive and have an adverse impact on subsequent processing and product use.
