Description

Technical Field

[0001] This disclosure relates to the technical field of packaging box production, and in particular to a pressure-holding device and box body pressure-holding equipment for applying adhesive to the back of cigarette boxes. Background Technology

[0002] Currently, with the continuous improvement of people's living standards, the demand for cigarette boxes is also increasing. In the packaging industry, cigarette box sealing is a crucial step in the packaging production line. In the traditional cigarette box packaging process, the gaps between sealed cigarette boxes are generally sealed using hot melt adhesive or locally applied adhesive backing. This involves evenly applying hot melt adhesive to the back of the cigarette box, then closing the box. Once the adhesive has cured, the seal is complete, thus ensuring the airtightness and stability of the packaging.

[0003] However, during the packaging process, the curing time of hot melt adhesive is relatively short, resulting in insufficient adhesion of the hot melt adhesive to the cigarette box. In traditional cigarette box packaging, most of the pressing methods are done manually, which is inefficient and cannot guarantee that the pressing force and position are consistent each time. This can lead to situations where the cigarette box is not pressed tightly or the cigarette box shifts, thus affecting the packaging quality and efficiency. Utility Model Content

[0004] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a pressure-holding device and box-body pressure-holding equipment for pressing and tightening the adhesive backing of cigarette boxes.

[0005] The purpose of this disclosure is achieved through the following technical solution:

[0006] A pressure-holding device for applying adhesive to the back of cigarette boxes includes a bracket and a base, wherein the bracket is disposed on the base;

[0007] The pressure-holding device for applying adhesive to the back of a cigarette box further includes a pressing and fixing seat, a pressure-holding block, and a driving assembly. The pressing and fixing seat is disposed on the end face of the base and has a groove for placing the cigarette box body. The driving assembly is located above the bracket, which has a sliding hole. The driving assembly includes a driving cylinder, a movable plate, a spreading shaft, and a guide rod. The guide rod passes through the sliding hole and is slidably connected to the bracket. The pressure-holding block is connected to one end of the guide rod and is located on the side of the bracket adjacent to the base. The other end of the bracket is connected to the movable plate, which is located on the side of the bracket away from the base. The driving cylinder is mounted on the movable plate, and its power output end is connected to the spreading shaft.

[0008] In one embodiment, the pressure-holding block further includes a power output block and a compaction block, the power output block being connected to the guide rod, and the compaction block being connected to the bottom of the power output block and located above the pressing and fixing seat.

[0009] In one embodiment, the compaction block further includes a compaction block body and a pressing strip. The pressing strip is disposed at the bottom of the compaction block body, and the bottom of the pressing strip is provided with a pressing surface. The cross-sectional area of ​​the pressing surface is larger than the cross-sectional area of ​​the adhesive backing surface of the cigarette box body.

[0010] In one embodiment, one end of the guide rod is detachably connected to the bottom of the movable plate, and the other end of the guide rod slides through the end face of the bracket and is detachably connected to the compaction block.

[0011] In one embodiment, the drive assembly further includes a flange bearing component, the end face of the bracket has an installation port, the flange bearing component is disposed in the installation port, and the guide rod passes through the flange bearing component and is connected to the pressure holding block.

[0012] In one embodiment, the bracket includes a first side plate, a second side plate, and a crossbeam. One end of the first side plate is connected to the end face of the base, and the other end of the first side plate is connected to the first end of the crossbeam. One end of the second side plate is connected to the other side of the end face of the base, and the other end of the second side plate is connected to the second end of the crossbeam.

[0013] In one embodiment, the movable plate has a mounting groove with a through hole, the drive cylinder is disposed in the mounting groove, and the power output end of the drive cylinder passes through the through hole and is connected to the spreading shaft.

[0014] In one embodiment, the pressure-holding device for pressing the adhesive backing of the cigarette box further includes a controller, the controller being disposed on the end face of the bracket, the controller being electrically connected to the drive cylinder, and the controller being used to control the downward pressure of the pressure-holding block and the pressing duration of the cigarette box body.

[0015] In one embodiment, the pressing and fixing base includes a fixing member and a buffer pad, the groove is disposed in the fixing member, the buffer pad is disposed on the end face of the base, and the fixing member is disposed on the end face of the buffer pad.

[0016] A box-type pressure-holding device includes the pressure-holding device for pressing adhesive on the back of cigarette boxes as described in any of the above embodiments.

[0017] Compared with the prior art, this disclosure has at least the following advantages:

[0018] By setting a pressing and fixing seat on the end face of the base, and having a groove on the pressing and fixing seat, the cigarette box is placed in the groove. Because the power section of the drive cylinder is connected to the expansion shaft, and the drive cylinder is mounted on the movable plate, the drive cylinder will increase the power to act on the expansion shaft, causing the movable plate to move downward. The guide rod passes through the sliding hole and is slidably connected to the bracket. At the same time, the pressure holding block is connected to one end of the bracket, so that the pressure holding block moves downward with the trajectory of the movable plate. This allows the pressure holding block to approach and tightly press against the cigarette box placed in the groove of the pressing and fixing seat, thereby achieving the effect of applying pressure to the cigarette box. This ensures that the pressure holding block can press the cigarette box with consistent force each time, avoiding situations where the adhesive backing of the cigarette box is not pressed tightly or the adhesive backing area of ​​the cigarette box is shifted, thus ensuring the packaging quality and efficiency of the cigarette box during the adhesive backing process.

[0027] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0028] like Figure 1 As shown, a pressure-holding device 10 for pressing adhesive on the back of a cigarette box according to an embodiment includes a bracket 100 and a base 200, wherein the bracket 100 is disposed on the base 200;

[0029] The pressure-holding device 10 for applying adhesive to the back of cigarette boxes further includes a pressing and fixing seat 300, a pressure-holding block 400, and a driving assembly 500. The pressing and fixing seat 300 is disposed on the end face of the base 200 and has a groove 310 for placing the cigarette box body 600. The driving assembly 500 is located above the bracket 100, which has a sliding hole 150. The driving assembly 500 includes a driving cylinder 540, a movable plate 520, a spreading shaft 550, and a guide rod 510. The guide rod 510 passes through the sliding hole 150 and is slidably connected to the bracket 100. The pressure holding block 400 is connected to one end of the bracket 100 and is located on the side of the bracket 100 adjacent to the base 200. The other end of the bracket 100 is connected to the movable plate 520 and is located on the side of the bracket 100 away from the base 200. The drive cylinder 540 is mounted on the movable plate 520 and the power output end of the drive cylinder 540 is connected to the spreading shaft 550.

[0030] The working process of the pressure-holding device 10 for applying adhesive to the back of cigarette boxes is as follows: When it is necessary to hold pressure on the cigarette box body 600 of the pressing and fixing seat 300, because the power initial stage of the drive cylinder 540 is connected to the expansion shaft 550, and the drive cylinder 540 is installed on the movable plate 520, the drive cylinder 540 will increase the power to act on the expansion shaft 550, causing the movable plate 520 to move downward, and the guide rod 510 passes through the sliding hole 150 and is slidably connected to the bracket 100. At the same time, the pressure-holding block 400 is connected to one end of the bracket 100, so that the pressure-holding block 400 moves downward along the trajectory of the movable plate 520, thereby causing the pressure-holding block 400 to abut and press against the cigarette box body 600 located on the pressing and fixing seat 300. When the pressed and fixed cigarette box body 600 is pressed, the drive cylinder 540 will exert an upward lifting force on the opening shaft 550, causing the opening shaft 550 to drive the movable plate 520 to move upward. Since the movable plate 520 is connected to the pressure holding block 400 through the guide rod 510, the pressure holding block 400 is moved away from the pressing and fixing seat 300.

[0031] It is understood that by setting a pressing and fixing seat 300 on the end face of the base 200, and providing a groove 310 on the pressing and fixing seat 300, the cigarette box body 600 is placed in the groove 310; because the initial power section of the driving cylinder 540 is connected to the spreading shaft 550, and the driving cylinder 540 is mounted on the movable plate 520, the driving cylinder 540 will increase the power acting on the spreading shaft 550, causing the movable plate 520 to move downward, and the guide rod 510 passes through the sliding hole 150 and is slidably connected to the bracket 100, while the pressure holding block 400 is connected to the bracket 100. At one end, the pressure-holding block 400 moves downward along the trajectory of the movable plate 520, allowing the pressure-holding block 400 to approach and tightly press against the cigarette box body 600 placed in the groove 310 of the pressing and fixing seat 300. This achieves the effect of applying pressure to the cigarette box body 600, ensuring that the pressure-holding block 400 can press the cigarette box body 600 with consistent force each time. This avoids situations where the adhesive on the back of the cigarette box body 600 is not pressed tightly or the adhesive area of ​​the cigarette box body 600 shifts, thus ensuring the packaging quality and efficiency of the cigarette box body 600 during the adhesive application process.

[0032] Combination Figure 1 and Figure 2 As shown, in one embodiment, the pressure holding block 400 further includes a power output block 410 and a compaction block 420. The power output block 410 is connected to the guide rod 510, and the compaction block 420 is connected to the bottom of the power output block 410 and located above the pressing and fixing seat 300. It is understood that the guide rod 510 of the drive assembly 500 is connected to the power output block 410, so that the guide rod 510 of the drive assembly 500 drives the power output block 410 to move downward. Since the compaction block 420 is connected to the bottom of the power output block 410 and is located above the pressing and fixing seat 300, the compaction block 420 moves to the top of the pressing and fixing seat 300 to press the cigarette box 600 placed in the pressing and fixing seat. The compaction block 420 can accurately align and contact the cigarette box 600 placed in the groove 310 of the pressing and fixing seat 300. At the same time, the compaction block 420 is designed and made of high hardness and wear-resistant material to ensure that it can always provide stable pressure during repeated pressure holding.

[0033] Combination Figure 1 and Figure 2As shown, in one embodiment, the compaction block 420 further includes a compaction block body 4210 and a pressing strip 4220. The pressing strip 4220 is disposed at the bottom of the compaction block body 4210. The bottom of the pressing strip 4220 is provided with a pressing surface 4221. The cross-sectional area of ​​the pressing surface 4221 is larger than the cross-sectional area of ​​the adhesive backing surface of the cigarette box body 600. It is understood that the compaction block body 4210 is connected to the power output block 410. When the power output block 410 moves downward, because the power output block 410 is connected to the compaction block body 4210, the compaction block body 4210 moves downward along with the power output block 410. And because the pressing strip 4220 is set at the bottom of the compaction block body 4210, when the compaction block body 4210 moves downward, the pressing strip 4220 will abut against the back of the cigarette box body 600, thereby pressing the adhesive backing of the cigarette box body 600. At the same time, the cross-sectional area of ​​the pressing surface 4221 is larger than the cross-sectional area of ​​the adhesive backing surface of the cigarette box body 600, ensuring that every part of the adhesive backing surface can be fully and evenly covered during the pressing process, avoiding incomplete adhesive backing or displacement problems caused by uneven pressure.

[0034] Combination Figure 2 and Figure 3 As shown, in one embodiment, one end of the guide rod 510 is detachably connected to the bottom of the movable plate 520, and the other end of the guide rod 510 slides through the end face of the bracket 100 and is detachably connected to the compaction block 420. It is understandable that the guide rod 510, as a key component connecting the movable plate 520 and the power output block 410 of the compaction block 420, ensures the stability and reliability of the entire drive system and improves the motion accuracy and efficiency of the pressure holding device. One end of the guide rod 510 is threaded to the bottom of the movable plate 520, and the other end slides through the end face of the bracket 100 and is directly connected to the power output block 410 of the compaction block 420, so that the movable plate 520 moves up and down under the drive of the drive cylinder 540. The guide rod 510, as a transmission medium, converts this motion into the vertical motion of the power output block 410. At the same time, the movable plate 520, as a stable support platform, can withstand the strong power from the drive cylinder 540 and evenly transmit it to the guide rod 510 and the compaction block 420, ensuring the stability and reliability of the drive assembly 500. In addition, the guide rod 510 is detachably connected to the movable plate 520 and the compaction block 420, which is convenient for replacing the guide rod 510 according to needs and actual conditions.

[0035] like Figure 3As shown, in one embodiment, the drive assembly 500 further includes a flange bearing 530. The end face of the bracket 100 has a mounting opening 110, and the flange bearing 530 is disposed within the mounting opening 110. The guide rod 510 passes through the flange bearing 530 and is connected to the pressure-holding block 400. It can be understood that by using the flange bearing 530 disposed within the mounting opening 110 on the end face of the bracket 100, and with the guide rod 510 passing through the bearing and connected to the pressure-holding block 400, the guide rod 510 moves downwards more smoothly. This enhances the stability and durability of the drive assembly 500, ensures the precise position and smooth operation of the guide rod 510 during lifting and lowering, and also facilitates assembly and maintenance.

[0036] like Figure 2 As shown, in one embodiment, the bracket 100 includes a first side plate 120, a second side plate 130, and a crossbeam 140. One end of the first side plate 120 is connected to the end face of the base 200, and the other end of the first side plate 120 is connected to the crossbeam 140. It can be understood that one end of the first side plate 120 is firmly connected to the end face of the base 200, and the other end of the first side plate 120 is connected to the crossbeam 140. Simultaneously, one end of the second side plate 130 is connected to the other side of the end face of the base 200, and the other end of the second side plate 130 is connected to the second end of the crossbeam 140. This allows the first side plate 120, the second side plate 130, and the crossbeam 140 to form a semi-sealed frame, which helps reduce the interference of external factors on the working state of the drive assembly 500 and the pressure holding block 400, improving the device's anti-interference capability and working accuracy.

[0037] like Figure 3 As shown, the movable plate 520 further includes a mounting groove 5210 with a through hole 5211. The drive cylinder 540 is disposed within the mounting groove 5210, and its power output end passes through the through hole 5211. It can be understood that with the mounting groove 5210 and the through hole 5211 in the movable plate 520, and the drive cylinder 540 disposed within the mounting groove 5210 with its power output end passing through the through hole 5211, the drive cylinder 540 transmits force to the movable plate 520. When the movable plate 520 descends, the guide rod 510 moves downward with it, thereby causing the pressure-holding block 400 to act on the cigarette box body 600, causing the compaction block 420 to abut against the adhesive backing surface of the cigarette box body 600.

[0038] Combination Figure 1 and Figure 3As shown, in one embodiment, the pressure-holding device 10 for applying adhesive to the back of the cigarette box further includes a controller 700. The controller 700 is disposed on the end face of the crossbeam 140 and electrically connected to the drive cylinder 540. The controller 700 is used to control the downward pressure of the pressure-holding block 400 and the pressing duration on the cigarette box body 600. It can be understood that by disposing of the controller 700 on the end face of the crossbeam 140 and electrically connecting it to the drive cylinder 540, the controller 700 issues commands, causing the drive cylinder 540 to receive these commands. Consequently, the controller 700 controls the downward pressure of the drive cylinder 540 on the pressure-holding block 400 and the pressing duration on the cigarette box body 600. The working power and working mode of the drive cylinder 540 can be adjusted according to different situations and needs.

[0039] like Figure 3 As shown, in one embodiment, the pressing and fixing base 300 includes a fixing member 320 and a buffer pad 330. The groove 310 is disposed in the fixing member 320, the buffer pad 330 is disposed on the end face of the base 200, and the fixing member 320 is disposed on the end face of the buffer pad 330. It is understood that the pressing and fixing base 300 includes a fixing member 320 and a buffer pad 330. The groove 310 is set in the fixing member 320. The cigarette box body 600 is placed in the groove 310 of the fixing member 320, so that the cigarette box body 600 can be fixed in the groove 310 of the fixing member 320 and will not slide or shift due to the force of the pressing block 420 when it is pressed. At the same time, the buffer pad 330 is set at the bottom of the fixing member 320, so that when the cigarette box body 600 placed in the fixing member 320 is subjected to pressure, the pressure of the fixing member 320 on the base 200 is reduced. Setting the fixing member 320 on the end face of the buffer pad 330 helps to reduce the pressure of the fixing member 320 on the base 200.

[0040] This application also provides a box-type pressure-holding device, including the pressure-holding device 10 for pressing the adhesive backing of cigarette boxes as described in any of the above embodiments. It can be understood that when the drive cylinder 540 of the drive assembly 500 is activated to provide power, the power output rod drives the pressure-holding block 400 to move, allowing the pressure-holding block 400 to approach and tightly press against the cigarette box body 600 placed in the groove 310 of the pressing and fixing seat 300. This achieves the effect of applying pressure to the cigarette box body 600, avoiding situations where the adhesive backing of the cigarette box body 600 is not pressed tightly or the adhesive backing area of ​​the cigarette box body 600 shifts.

[0041] Compared with the prior art, this disclosure has at least the following advantages:

[0042] A pressing and fixing seat 300 is provided on the end face of the base 200, and a groove 310 is provided on the pressing and fixing seat 300. The cigarette box body 600 is placed in the groove 310. Because the power initial stage of the driving cylinder 540 is connected to the expansion shaft 550, and the driving cylinder 540 is installed on the movable plate 520, the driving cylinder 540 will increase the power acting on the expansion shaft 550, causing the movable plate 520 to move downward. The guide rod 510 passes through the sliding hole 150 and is slidably connected to the bracket 100. At the same time, the pressure holding block 400 is connected to one end of the bracket 100. This allows the pressure-holding block 400 to move downwards along the trajectory of the movable plate 520, enabling it to approach and tightly press against the cigarette box body 600 placed in the groove 310 of the pressing and fixing seat 300. This achieves the effect of applying pressure to the cigarette box body 600, ensuring that the pressure-holding block 400 can apply consistent pressure to the cigarette box body 600 each time. This avoids situations where the adhesive backing of the cigarette box body 600 is not pressed tightly or the adhesive backing area of ​​the cigarette box body 600 shifts, thus ensuring the packaging quality and efficiency of the cigarette box body 600 during the adhesive backing process.

[0043] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
