Description

Technical Field

[0001] This utility model relates to the field of cigarette box processing technology, and more specifically, to an automated cigarette box folding and gluing device. Background Technology

[0002] During the manufacturing process, cigarette boxes are usually bonded together by applying glue to the folded edges. Existing cigarette box folding and gluing devices complete the folding and gluing of cigarette boxes by pressing the glue strip on the glue application mechanism into contact with the glue brush roller with the glue applied.

[0003] However, since the folding lengths of cigarette boxes of different specifications vary, the length of the area requiring gluing also varies. Existing cigarette box folding gluing devices apply glue to the entire surface of the gluing roller during each application, which undoubtedly wastes glue. Glue adhering to the gluing roller for a long time may solidify on the roller, making subsequent cleaning difficult. Furthermore, as glue is consumed during processing, the amount of glue adhering to the gluing roller surface decreases when glue is insufficient, resulting in less glue applied to the cigarette box folding edges and weak adhesion. Therefore, this invention proposes an automated cigarette box folding gluing device to solve the above problems. Utility Model Content

[0009] Preferably, the glue box is provided with a glue holding tank and a glue brushing tank inside, the pressure stabilizing component can slide inside the glue holding tank, and an elastic component is provided inside the glue holding tank. One end of the elastic component is fixedly connected to the inner wall of the glue holding tank, and the other end is fixedly connected to the pressure stabilizing component.

[0010] Preferably, a cylinder is provided at one end of the device body, and a support member is slidably connected inside the cylinder. One end of the support member passes through the cylinder and is fixedly connected to the glue box.

As the glue is consumed, the pressure stabilizing component slides within the glue-holding tank, preventing insufficient glue from reducing the amount of glue adhering to the glue roller surface, thus avoiding insufficient glue application to the cigarette box edge.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0026] Example 1

[0027] In actual production, glue adheres to the entire surface of the glue roller each time glue is applied, resulting in glue waste. This embodiment is invented to solve the above problem.

[0028] Please see Figures 1 to 7 As shown, an automated cigarette box edge-folding and gluing device according to an embodiment of the present invention includes a device body 1, a gluing component 2, a glue box 3, an adjusting component 4, and a pressure stabilizing component 5. A glue brush roller 31 is provided inside the glue box 3. The adjusting component 4 includes a movable component 41 disposed inside the glue box 3. The movable component 41 can change the area of ​​the contact area between the glue and the glue brush roller 31 according to the length of the gluing area. The pressure stabilizing component 5 is disposed inside the glue box 3. The pressure stabilizing component 5 can squeeze the glue during the gluing process to make it contact the surface of the glue brush roller 31.

[0029] Please see Figure 3 and Figure 4 As shown, there are two movable parts 41, which are symmetrically arranged along the mid-section of the glue box 3. One end of each movable part 41 is fixedly connected to a sealing element 42. Adjustment grooves 43 are provided at both ends of the glue box 3. A rotating shaft is rotatably connected inside each adjustment groove 43. The end of each sealing element 42 away from the movable part 41 is wound onto the corresponding rotating shaft. A coil spring is provided inside the rotating shaft. The sealing element 42 is made of flexible material. When the movable part 41 moves toward the mid-section of the glue box 3, the movable part 41 drives the sealing element 42 to extend out of the adjustment groove 43. The rotating shaft rotates, causing the coil spring to be stretched. Conversely, the coil spring returns to its original position, and the sealing element 42 is wound back onto the rotating shaft.

[0030] Please see Figure 2 and Figure 3 As shown, a first piston cylinder 44 is fixedly connected inside the glue box 3. Two first piston plates 441 are slidably connected inside the first piston cylinder 44. The two first piston plates 441 correspond to the movable part 41 respectively, and the first piston plates 441 and the movable part 41 are magnetically coupled.

[0031] Please see Figure 5 and Figure 6As shown, the adhesive application assembly 2 has two second piston cylinders 21 fixedly connected inside. Each second piston cylinder 21 has a fixing member 22 slidably connected inside. One end of each second piston cylinder 21 is provided with a second vent hole 211. The side wall of the first piston cylinder 44 is provided with a first vent hole 442. The two second vent holes 211 are connected to the first vent hole 442. An adhesive strip is detachably connected between the two fixing members 22. The top of the adhesive box 3 is provided with a clearance hole corresponding to the first vent hole 442. The end of the second piston cylinder 21 away from the second vent hole 211 is provided with a through hole connected to the air source. The adhesive strip matches the area of ​​the cigarette box edge that needs to be glued. The adhesive strip is detachably connected to the two fixing members 22. This is existing technology and will not be described in detail here.

[0032] Please see Figure 4 As shown, the glue box 3 is provided with a glue holding tank 33 and a glue brushing tank 32 inside. The pressure stabilizing component 5 can slide inside the glue holding tank 33. An elastic component is provided inside the glue holding tank 33. One end of the elastic component is fixedly connected to the inner wall of the glue holding tank 33, and the other end is fixedly connected to the pressure stabilizing component 5. A cover is provided on the top of the glue holding tank 33.

[0033] Please see Figure 2 As shown, a cylinder 11 is provided at one end of the equipment body 1. A support member 12 is slidably connected inside the cylinder 11. One end of the support member 12 passes through the cylinder 11 and is fixedly connected to the glue box 3. A third vent hole 111 is provided at one end of the cylinder 11, and a fourth vent hole 331 is provided at one end of the glue tank 33. The third vent hole 111 and the fourth vent hole 331 are connected. A one-way valve and a pressure relief valve are provided at the third vent hole 111.

[0034] Please see Figure 7 As shown, a third piston cylinder 13 is fixedly connected to both sides of the device body 1, and a second piston plate 131 is slidably connected inside the third piston cylinder 13. A slider is fixedly connected to both sides of the glue application assembly 2, and the slider is slidably connected to the outer wall of the third piston cylinder 13. The second piston plate 131 is magnetically coupled to the slider.

[0035] Please see Figure 7 As shown, the cylinder 11 has an air inlet at one end near the third vent 111 and a through hole connected to the air source at the other end away from the third vent 111. Each third piston cylinder 13 has a through hole connected to the air source at one end. Slide rails are fixedly connected to both sides of the equipment body 1. The glue box 3 is slidably connected to the slide rails. A motor is fixedly connected to the side wall of the glue box 3. The output end of the motor is connected to the glue brush roller 31. A control system for controlling the air source and the motor is installed inside the equipment body 1.

[0036] In use, first place the cigarette box to be glued under the glue application assembly 2. Inflate the second piston cylinder 21 with air from the air source, causing the two fixing parts 22 to slide inside the corresponding second piston cylinder 21. Adjust the distance between the two fixing parts 22 according to the cigarette box specifications. When the distance between the two fixing parts 22 matches the area of ​​the cigarette box edge to be glued, the worker installs the adhesive strip onto the two fixing parts 22. As the fixing parts 22 slide inside the second piston cylinder 21, the gas at the end of the second piston cylinder 21 near the second vent 211 enters the first piston cylinder 44 through the second vent 211 and the first vent 442, thereby causing the two first piston plates 441 to move away from the glue box 3. The mid-section moves in the direction of the movement, causing the first piston plate 441 to drive the corresponding movable part 41 to slide inside the glue box 3. This causes the seal 42 to move into the adjusting groove 43. The coil spring inside the rotating shaft contracts, and the seal 42 is wound up. The glue inside the glue tank 33 enters the glue brushing groove 32 between the two movable parts 41 and comes into contact with the glue brushing roller 31. At this time, the glue application program is started. The control system controls the air source to extract the gas inside the cylinder 11, causing the support 12 to drive the glue box 3 to move closer to the glue application assembly 2. At the same time as the air source extracts the gas inside the cylinder 11, the motor rotates forward, causing the glue brushing roller 31 to rotate. The glue between the two movable parts 41 adheres to the surface of the glue brushing roller 31. When the glue brushing roller 31 moves... When the adhesive strip is directly above the cylinder 11, the air source simultaneously extracts gas from the cylinder 11, the motor stops, and the air source simultaneously inflates the third piston cylinder 13, causing the second piston plate 131 to move downwards, thus causing the adhesive application assembly 2 to move downwards. When the adhesive application assembly 2 moves to the point where the adhesive strip contacts the brush roller 31, the air source extracts gas from the third piston cylinder 13, causing the adhesive application assembly 2 to move upwards. When the adhesive application assembly 2 moves to the point where the adhesive strip and brush roller 31 are no longer in contact, the air source stops extracting gas from the third piston cylinder 13 and inflates the cylinder 11, causing the support member 12 to move the glue box 3 to the initial position. After the glue box 3 moves to the initial position, the air source stops inflating the cylinder 11 and inflates the third piston cylinder 13. The air source draws out the gas from the third piston cylinder 13, causing the gluing component 2 to slide downwards and apply glue to the edge of the cigarette box. After gluing is completed, the air source extracts the gas from the third piston cylinder 13, causing the gluing component 2 to move upwards back to its initial position. By repeatedly starting the gluing program, a batch of cigarette box edges of the same specifications are glued. The movement of the fixed part 22 drives the movement of the movable part 41, so that the distance between the two movable parts 41 is equal to the length of the cigarette box edge that needs to be glued. The movable part 41 and the sealing part 42 are used to seal the glue tank 33, so that the glue can only enter the glue tank 32 through the distance between the two movable parts 41. As a result, during each gluing process, the entire surface of the glue roller 31 will be covered with glue, causing glue waste and subsequent cleaning inconvenience.

[0037] Example 2

[0038] In actual use, it was found that when there is insufficient glue, the amount of glue adhering to the surface of the glue roller will decrease accordingly, resulting in less glue on the folded edges of the cigarette box and the problem that the folded edges of the cigarette box are not firmly attached. Further improvements have been made based on the above embodiments.

[0039] Based on the above embodiments, during use, as the glue box 3 moves towards the glue application component 2, external gas enters the cylinder 11 through the air inlet. When the glue box 3 moves away from the glue application component 2, the gas near the third vent 111 of the cylinder 11 enters the glue box 3 through the third vent 111 and the fourth vent 331. This causes the pressure stabilizer 5 to move and squeeze the internal glue in the glue tank 33, and the elastic element is stretched. By delivering gas into the glue box 3 once for each glue application process, the pressure stabilizer 5 slides in the glue tank 33 as the glue is consumed. This prevents the amount of glue adhering to the surface of the glue roller 31 from decreasing when there is insufficient glue, thus avoiding the problem of insufficient glue application on the cigarette box folding edge.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
