Description

Technical Field

[0001] This invention relates to the field of adhesive coating technology for cigarette boxes, and more particularly to adhesive coating equipment for cigarette box production. Background Technology

[0002] As the core carrier of cigarette packaging, the bonding quality of cigarette boxes directly affects the sealing, aesthetics, and overall quality of the packaging. In the production process of cigarette box packaging, the glue coating process is one of the key steps. Screen printing glue coating technology is a new type of glue coating method. This technology uses a screen as a template. By pre-making a hollow pattern on the screen that precisely matches the glue coating area of ​​the cigarette box, the glue is accurately transferred to the designated position through the mesh under the pressure of the squeegee. Screen printing glue coating can flexibly make plates according to different spraying areas and shapes, and is suitable for the glue coating needs of different parts such as cigarette box seals, inner frame paper, and trademark paper. It has been applied in some high-end packaging fields.

[0003] However, in actual production, it was found that some adhesive could not be effectively utilized during the screen printing coating process. Specifically, the perforated pattern on the screen does not cover the entire screen surface, and the non-perforated areas (i.e., blank areas that do not require adhesive coating) occupy most of the screen area. During the reciprocating motion of the adhesive being pushed by the squeegee, the adhesive accumulated above the non-perforated areas cannot be transferred to the product through the mesh and is constantly scraped back and forth on the screen surface with the squeegee. This not only causes long-term retention and waste of adhesive, but also easily leads to the adhesive drying and forming a skin on the screen surface, further clogging the mesh and affecting the subsequent coating quality. Summary of the Invention

[0004] In order to overcome the shortcomings mentioned in the background art, the present invention provides a coating equipment for cigarette box production.

[0005] The technical implementation of the present invention is as follows: a coating equipment for cigarette box production includes a fixed frame, an electric slide mounted on the fixed frame, a scraper module for pushing materials mounted on the electric slide, a screen printing mesh for defining the coating position on the cigarette box mounted on the electric slide, two symmetrically distributed support rollers rotatably connected to the electric slide, two symmetrically distributed connecting plates slidably connected to the electric slide, a permeable membrane for carrying adhesive being fixedly connected between the two symmetrically distributed connecting plates, the permeable membrane being wrapped around the outside of the two symmetrically distributed support rollers, a first elastic element being provided between one of the connecting plates and the electric slide, and a drive assembly for driving the other connecting plate to move on the electric slide.

[0006] More preferably, the drive assembly includes a first rotating shaft rotatably connected to the electric slide, a second rotating shaft rotatably connected to the electric slide, a drive member fixedly connected to the electric slide, an output shaft of the drive member fixedly connected to the first rotating shaft, a first gear fixedly connected to the first rotating shaft, a second gear fixedly connected to the second rotating shaft and driven by the first gear, and a pull rope fixedly connected between the second rotating shaft and the corresponding connecting plate.

[0007] More preferably, the electric carriage is slidably connected to two symmetrically distributed baffles, which are located between two symmetrically distributed support rollers, and the baffles are in contact with the permeable membrane.

[0008] More preferably, the electric carriage is rotatably connected to two adjusting shafts, both of which are threadedly connected to two symmetrically distributed baffles, and a transmission module is provided between the two adjusting shafts.

[0009] More preferably, the electric carriage is slidably connected by four rectangularly distributed connecting shafts, and two adjacent connecting shafts are jointly fixedly connected to a fixing plate, with the screen printing mesh fixedly connected between the two fixing plates.

[0010] More preferably, a second elastic element is provided between the connecting shaft and the electric carriage.

[0011] More preferably, the electric carriage is fixedly connected to two symmetrically distributed brackets, the brackets are slidably connected to racks, the first rotating shaft is fixedly connected to two symmetrically distributed third gears, the third gears mesh with the adjacent racks, and the racks are fixedly connected to two symmetrically distributed pressing blocks, the pressing blocks being used to press the corresponding connecting shafts.

[0012] More preferably, the first gear is a missing gear.

[0013] More preferably, the electric carriage is fixedly connected to a connecting frame, the connecting frame is slidably connected to a limit pin, the limit pin is used to limit the second gear, and a third elastic element is provided between the limit pin and the connecting frame.

[0014] More preferably, the elastic coefficient of the first elastic element is smaller than that of the third elastic element.

[0015] Compared with the prior art, the technical effects achieved by the present invention are as follows: 1. The present invention carries the adhesive liquid through the permeable membrane and changes its relative position with the screen printing mesh. Without interrupting the adhesive coating process, the adhesive liquid on the permeable membrane can be actively guided to different areas of the screen printing mesh, so that the adhesive liquid originally accumulated in the non-perforated area can be redistributed and utilized, thereby improving the overall utilization rate of the adhesive liquid and reducing the waste of adhesive liquid.

[0016] 2. By adjusting the position of the two baffles so that they fit against the scraper in the middle, the working area on the permeable membrane can be defined. At the same time, when the permeable membrane moves, the baffles can push the adhesive on it toward the center of the permeable membrane, reducing the ineffective flow and waste of adhesive to non-coated areas, thereby improving the utilization rate of adhesive.

[0017] 3. The second elastic element, which is always in a stretched state, keeps the screen printing mesh tightly attached to the underside of the adhesive membrane, improving the adhesion between the two and ensuring uniform and stable adhesive transfer. At the same time, when the position of the adhesive membrane is changed, the screen printing mesh is separated from the adhesive membrane first, which can effectively avoid excessive frictional resistance when the two slide relative to each other, prevent damage to the adhesive membrane and screen printing mesh, and extend the service life of the components.

Detailed Implementation

[0020] The above solution will be further described below with reference to specific embodiments. It should be understood that these embodiments are for illustrating this application and are not intended to limit the scope of this application. The implementation conditions used in the embodiments can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are usually the conditions in routine experiments.

[0021] In screen printing adhesive application, because the stencil pattern only occupies a part of the screen, a large amount of adhesive remains in the non-stencil area. Despite the reciprocating motion of the squeegee, it cannot be transferred to the product, resulting in adhesive waste. Long-term retention can also cause it to dry and form a skin, clogging the mesh and affecting the quality and stability of the adhesive application. Example 1

[0022] This embodiment provides a coating equipment for cigarette box production, which improves the utilization rate of adhesive liquid.

[0023] See Figures 1-3 The system includes a fixed frame 1, which is installed above the conveyor belt. An electric slide 2 is mounted on the fixed frame 1, and a power module (not shown in the figure) is also mounted on the fixed frame 1. The power module drives the electric slide 2 to slide up and down along the fixed frame 1. A scraper module 3 for pushing materials is mounted on the electric slide 2. The scraper module 3 consists of an electric slide rail, a transmission frame, a scraper, and an electric push rod. The electric slide rail is fixedly connected to the electric slide 2, and its electric slider is fixedly connected to the transmission frame. The scraper is slidably connected to the transmission frame, and the transmission frame is fixedly connected to the electric push rod. The telescopic end of the electric push rod is fixedly connected to the scraper, meaning the electric push rod can control the scraper to slide up and down. Simultaneously, the electric slide rail drives the scraper to slide left and right via the transmission frame, thus pushing the adhesive with the scraper. A screen printing mesh 4 is mounted on the electric slide 2 to define the adhesive application position on the cigarette box. In this embodiment, the screen printing mesh 4 is fixedly connected to the electric slide 2, but this is limited to this embodiment. The movable slide 2 is rotatably connected to two symmetrically distributed support rollers 5, and the electric slide 2 is slidably connected to two symmetrically distributed connecting plates 6. The two connecting plates 6 are located on the front and rear sides of the electric slide 2, respectively. A permeable membrane 7 for carrying adhesive is fixedly connected between the two symmetrically distributed connecting plates 6. Adhesive can pass through at any position of the permeable membrane 7. The area through which the adhesive passes through the permeable membrane 7 overlaps with the area through which the adhesive passes through the screen printing mesh 4, which is the area for applying adhesive to the cigarette box. In this embodiment, the permeable membrane 7 is always in contact with the screen printing mesh 4, but only in this embodiment. The permeable membrane 7 is wrapped around the outside of the two symmetrically distributed support rollers 5. A first elastic element 8 is provided between the front connecting plate 6 and the electric slide 2. The first elastic element 8 is a spring, which is always in a compressed state under the action of the support rollers 5 and the permeable membrane 7, so as to keep the permeable membrane 7 always in a taut state. The electric slide 2 is provided with a drive component for driving the rear connecting plate 6 to move.

[0024] See Figures 1-3The drive assembly includes a first rotating shaft 201, which is rotatably connected to the rear side of the electric slide 2. A second rotating shaft 202 is rotatably connected to the rear side of the electric slide 2. A drive component 203, which is a servo motor, is fixedly connected to the left side of the electric slide 2. The output shaft of the drive component 203 is fixedly connected to the first rotating shaft 201. A first gear 204 is fixedly connected to the first rotating shaft 201. A second gear 205, which is driven by the first gear 204, is fixedly connected to the second rotating shaft 202. In this embodiment, the first gear 204 and the second gear 205 are always in a meshed state, but only in this embodiment. Two symmetrically distributed pull ropes 206 are fixedly connected between the second rotating shaft 202 and the corresponding connecting plate 6. In the initial state, the pull ropes 206 are not wrapped around the outside of the second rotating shaft 202. The output shaft of the drive component 203 winds up the two symmetrically distributed pull ropes 206 through the first rotating shaft 201, the first gear 204, the second gear 205, and the second rotating shaft 202.

[0025] See Figure 1 , Figure 2 and Figure 4 The electric slide 2 is slidably connected to two symmetrically distributed baffles 301, which are located between two symmetrically distributed support rollers 5. The baffles 301 are in contact with the adhesive membrane 7 and are used to restrict the flow area of ​​the adhesive. The electric slide 2 is rotatably connected to two adjusting shafts 302, which are located on the left and right sides of the electric slide 2 respectively. The adjusting shafts 302 are provided with two symmetrically distributed threads, which are of the same type and distribution. Both adjusting shafts 302 are threadedly connected to the two symmetrically distributed baffles 301. The two adjusting shafts 302 can drive the two symmetrically distributed baffles 301 to slide in opposite directions and back directions. A handle can be fixedly connected to the rear side of the adjusting shafts 302 for easy rotation by the operator. A transmission module 303 is provided between the two symmetrically distributed adjusting shafts 302. The transmission module 303 consists of two sprockets and a chain. The two sprockets are fixedly connected to the front side of the two adjusting shafts 302 respectively, and the chain is wound around the outside of the two sprockets.

[0026] Working principle: This device is installed above the conveyor belt. When it is necessary to apply glue to the cigarette box, the glue is poured onto the upper surface of the permeable membrane 7 and evenly spread on one side of the upper surface of the permeable membrane 7. Then, the conveyor belt carries the cigarette box to the screen printing position of this device and stops conveying the cigarette box. Then, the electric slide 2 slides down along the fixed frame 1, so that the electric slide 2 carries the screen printing mesh 4 on it to adhere to the cigarette box on the conveyor belt. Then, the scraper module 3 is turned on. The scraper module 3 pushes the permeable membrane 7 to reciprocate once, so that the glue on the permeable membrane 7 passes through the permeable membrane 7 and the screen printing mesh 4 and adheres to the cigarette box, thus completing the glue application of the cigarette box. Then, the electric slide 2 slides up along the fixed frame 1 to the initial position. At the same time, the electric slide 2 carries the screen printing mesh 4 on it to separate from the cigarette box. Then, the conveyor belt is turned on again to move the next cigarette box to the glue application position of this device, and so on.

[0027] During the above process, when the conveyor belt switches to the next cigarette box and enters the glue application position, the drive unit 203 is activated. The output shaft of the drive unit 203 drives the first rotating shaft 201 to rotate. The first rotating shaft 201 drives the second rotating shaft 202 to rotate through the first gear 204 and the second gear 205 on it. This causes the second rotating shaft 202 to wind up two symmetrically distributed pull ropes 206. The two pull ropes 206 pull the rear connecting plate 6, and the rear connecting plate 6 slides upward along the electric slide 2. At this moment, the rear connecting plate 6 drives the adhesive membrane 7 to move along the two support rollers 5. At the same time, the front connecting plate 6 slides downward along the electric slide 2 under the force of the adhesive membrane 7. An elastic element 8 is compressed, causing the adhesive membrane 7 to slide against the screen printing screen 4, changing the distribution of the adhesive relative to the screen printing screen 4 and making even use of the adhesive on the adhesive membrane 7. When the adhesive membrane 7 slides relative to the screen printing screen 4 to a specific position, the drive element 203 is turned off (adjusted in real time according to the adhesive application area and position of the cigarette box). When the adhesive application work of this round of cigarette box is completed, the output shaft of the drive element 203 drives the first rotating shaft 201 to reset to the initial position. At the same time, the first elastic element 8 resets and pulls the rear connecting plate 6 to reset to the initial position. The adhesive membrane 7 drives the adhesive on it to reset relative to the screen printing screen 4 to the initial position. This cycle continues until the adhesive application work of the cigarette box is completed.

[0028] Before applying adhesive to the cigarette box, the working area of ​​the permeable membrane 7 can be defined according to the adhesive application area of ​​the cigarette box. This reduces the amount of adhesive flowing to non-working areas and improves the utilization rate of the adhesive. The operator first changes the scraper model in the scraper module 3 according to the adhesive application area of ​​the cigarette box. Then, one of the adjustment shafts 302 is rotated. The adjustment shaft 302 drives the other adjustment shaft 302 to rotate synchronously through the transmission module 303. The two adjustment shafts 302 drive two symmetrically distributed baffles 301 to move back or forth along the electric slide 2, so that the opposite sides of the two baffles 301 are in contact with the scraper in the scraper module 3. Then, the rotation of the adjustment shaft 302 is stopped. This restricts the working area on the permeable membrane 7 and improves the utilization rate of the adhesive. Example 2

[0029] This embodiment provides a coating equipment for cigarette box production, which is a further improvement on the basis of Embodiment 1.

[0030] See Figure 2 , Figure 3 and Figure 5 The electric slide 2 is slidably connected to four rectangularly distributed connecting shafts 401, which are located at the four inner corners of the electric slide 2. Two adjacent connecting shafts 401 are fixedly connected to a fixing plate 402. A screen printing screen 4 is fixedly connected between the two fixing plates 402 and to the lower side of the fixing plate 402. A second elastic element 403, a tension spring, is provided between the connecting shafts 401 and the electric slide 2. The second elastic element 403 is always in a stretched state under the support of two support rollers 5. The second elastic element 403 is used to drive the screen printing screen 4 to adhere to the lower side of the transparent film 7 via the corresponding connecting shafts 401 and fixing plates 402. The electric slide 2 is fixedly connected to two symmetrically distributed brackets 501, located on the left and right sides of the electric slide 2. Each bracket 501 is slidably connected to a rack 502. A first rotating shaft 201 is fixedly connected to two symmetrically distributed third gears 503. 503 meshes with the adjacent rack 502. When the first rotating shaft 201 rotates, it can drive the two racks 502 to move through the third gears 503 at both ends. Two symmetrically distributed pressing blocks 504 are fixedly connected to the racks 502. The pressing blocks 504 have an isosceles trapezoidal structure, with the upper base of the pressing block 504 located at the lower part. The pressing blocks 504 are used to press the corresponding connecting shaft 401. The racks 502 drive the pressing blocks 504 on them to press the corresponding connecting shaft 401, so that the connecting shaft 401 can pass through. The corresponding fixing plate 402 drives the screen printing mesh 4 to separate from the adhesive membrane 7. The first gear 204 is missing a gear. The middle part of the missing tooth area of ​​the first gear 204 faces the second gear 205. The length of the bottom of the extrusion block 504 is the same as the distance of the arc corresponding to the central angle of the tooth part of the first gear 204. The degree of the central angle corresponding to the tooth part of the first gear 204 and the length of the bottom of the extrusion block 504 are changed according to the distribution of the adhesive area of ​​the cigarette box. That is, the model of the first gear 204 and the model of the extrusion block 504 are changed.

[0031] See Figure 2 and Figure 6 The electric slide 2 is fixedly connected to a connecting frame 601. The connecting frame 601 is slidably connected to a limiting pin 602. The limiting pin 602 has symmetrically distributed inclined surfaces, which facilitates pushing the limiting pin 602 when the second gear 205 is driven to rotate. The limiting pin 602 is used to limit the second gear 205. A third elastic element 603 is provided between the limiting pin 602 and the connecting frame 601. The elastic coefficient of the first elastic element 8 is less than the elastic coefficient of the third elastic element 603.

[0032] Working principle: When the permeable membrane 7 is pulled to change position relative to the screen printing screen 4, the output shaft of the drive component 203 drives the first rotating shaft 201 to rotate one revolution. First, the first rotating shaft 201 drives the third gears 503 at both ends to rotate synchronously. At this moment, the first gear 204 does not mesh with the second gear 205, that is, the second rotating shaft 202 cannot drive the connecting plate 6 on the rear side to move through the pull rope 206. The third gear 503 drives the adjacent rack 502 to slide along the bracket 501, so that the rack 502 drives the pressing block 504 on it to move synchronously. The pressing block 504 contacts and presses the corresponding connecting shaft 401, so that the connecting shaft 401 is subjected to the pressing force and slides downward along the electric slide 2. At the same time, the second elastic element 403 is further stretched. The four connecting shafts 401 drive the screen printing screen 4 to move downward through the two fixed plates 402, so that the screen printing screen 4 is separated from the permeable membrane 7. When the connecting shaft 401 is located at the connection between the lower side of the corresponding pressing block 504 and the inclined surface At this time, the first gear 204 and the second gear 205 are engaged. At this moment, the first gear 204 drives the second rotating shaft 202 to rotate through the second gear 205, so that the second rotating shaft 202 changes the position of the permeable membrane 7 through the pull rope 206 and the connecting plate 6 on the rear side. This continues until the connecting shaft 401 slides to the connection point between the other inclined surface and the lower side of the corresponding extrusion block 504. At this time, the first gear 204 and the second gear 205 disengage. At this moment, the second rotating shaft 202 cannot drive the connecting plate 6 on the rear side to move through the pull rope 206. Then, the connecting shaft 401 slides along the other inclined surface of the corresponding extrusion block 504. The second elastic element 403 gradually drives the corresponding connecting shaft 401 to reset. The four connecting shafts 401 drive the screen printing screen 4 to reset and adhere to the permeable membrane 7 through the two fixing plates 402. After the screen printing screen 4 and the permeable membrane 7 are separated, the position of the permeable membrane 7 is changed to prevent the large sliding resistance between the two from damaging the permeable membrane 7 and the screen printing screen 4.

[0033] During the above process, while the second gear 205 drives the second rotating shaft 202 to rotate, the second gear 205 presses the corresponding limiting pin 602, causing the limiting pin 602 to slide along the connecting frame 601. At the same time, the third elastic element 603 is stretched until the first gear 204 disengages from the second gear 205. The limiting pin 602 limits the second gear 205, thereby locking the second rotating shaft 202 in the winding state of the pull rope 206 and stabilizing the state of the transparent film 7 relative to the screen printing screen 4.

[0034] During the above process, the second elastic element 403, which is always in a stretched state, pulls the corresponding connecting shaft 401, thereby causing the four connecting shafts 401 and the two fixing plates 402 to drive the screen printing screen 4 to fit tightly against the lower side of the adhesive membrane 7, improving the degree of adhesion between the two and reducing the probability of gaps between them. When the adhesive coating work of the cigarette box is completed, the drive element 203 is turned on, and the output shaft of the drive element 203 drives the first rotating shaft 201 to reset, that is, the above switching principle is reversed. This resets the position of the adhesive membrane 7 relative to the screen printing screen 4 to the initial position.

[0035] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
