Description

Technical Field

[0001] The invention relates to the technical field of cigarette packing, and in particular to a non-woven fabric automatic cigarette packing device. Background Art

[0002] The packaging process of traditional packaging machines, whether it is a standard cigarette packaging machine, a special-standard integrated packaging machine or other forms of packaging machines, is composed of three major components: stacking mechanism, PE film wrapping mechanism and heating equipment. The stacking mechanism of the standard cigarette packaging machine only needs to stack the standard cigarettes and then transport them to the PE film wrapping part. The stacking mechanism of the special-standard integrated packaging machine requires standard cigarettes, slim cigarettes, and special-shaped cigarettes to be stacked, and then the three are combined together and transported to the PE film wrapping part, and then the stacked cigarettes are wrapped with PE film, and then the PE film is cut with a sealing and cutting device, and finally the PE film is heated by a heating device to shrink the PE film, and the stacked cigarettes are wrapped tightly to complete the cigarette packing.

[0003] Among them, PE film is a plastic product with polyethylene as the main raw material. Although heat shrink film is economical and convenient, polyethylene basically cannot be degraded normally in the natural environment. It has a serious impact on the environment. In 2005, the World Health Organization's International Agency for Research on Cancer announced that polyethylene is on the list of carcinogens. When heat shrink film is used to package cigarettes, the heat shrink film needs to be heated, which consumes a lot of electricity. The heat radiation generated and the volatilized gases during the heating process of the heat shrink film are harmful to health. Now the country pays more and more attention to environmental protection, and it is clearly not recommended to use heat shrink film in new projects.

[0004] The film feeding mechanism of the traditional packaging machine will first consume the film buffered above the gravity rod when feeding the film. When the cigarette pushing action is too fast, the film feeding speed is too fast, and the film buffered above the gravity rod will be consumed while pulling the film roll, causing the film roll to fall off the roll support roller. Slowing down the cigarette pushing action will affect the overall efficiency of the packaging machine.

[0005] In addition, the roll film replacement of traditional packaging machines is based on manual identification and judgment. This method requires workers to constantly pay attention to the use of the roll film. If the workers fail to discover that the roll film is used up in time, the equipment will be shut down due to lack of film. After the shutdown, the film needs to be re-threaded. This process takes a long time, seriously affecting the working efficiency of the packaging machine. Summary of the invention

[0026] The packaging process is as follows:

[0027] Two non-woven fabric rolls 8 are respectively on the upper non-woven fabric roll automatic unloading mechanism 9 and the lower non-woven fabric roll automatic unloading mechanism 10, and the free ends are led out to the ultrasonic sealing and cutting mechanism 2 through the traction components correspondingly arranged on the support frame 1, and the ends are welded to each other. The cigarette strips are stacked at the material conveying and laminating mechanism 6, and are pushed horizontally to the packaging table 3 by the material pushing device 7. The pushing process will pass through the ultrasonic sealing and cutting mechanism 2 (the rolling belts of the two non-woven fabric rolls 8 all pass through the ultrasonic sealing and cutting mechanism 2), and finally pushed to the packaging table 3 in front of the ultrasonic sealing and cutting mechanism 2, and then stretched The compression and positioning device 4 squeezes and positions the cigarette pack a half-wrapped with non-woven fabric on the packaging table 3. Next, the ultrasonic sealing and cutting mechanism 2 seals and cuts the two non-woven fabrics behind the cigarette at the rear side of the cigarette pile. After the sealing and cutting is completed, the cigarette pile is removed to continue the next packaging. During the entire packaging process, the upper non-woven fabric roll automatic feeding mechanism 9 and the lower non-woven fabric roll automatic feeding mechanism 10 can autonomously unwind, improve the situation where the non-woven fabric roll belt is not smoothly conveyed and needs to be shut down for maintenance, enhance the performance of the equipment to operate continuously, and improve the packaging efficiency.

[0028] As a preferred embodiment, the support frame 1 includes a movable base 11 and a front frame 12, the front frame 12 is vertically arranged at the front side of the upper end of the base 11, the ultrasonic sealing and cutting mechanism 2 is installed in the front frame 12, and the upper traction roller group 13 and the lower traction roller group 14 extending in the left and right directions are arranged at intervals above and below the rear side of the front frame 12 corresponding to the position of the ultrasonic sealing and cutting mechanism 2, the upper traction roller group 13 and the lower traction roller group 14 are respectively used to pull two non-woven fabrics distributed up and down, so that the two non-woven fabrics can be welded and cut through the ultrasonic sealing and cutting mechanism 2, the packaging table 3 is installed at the upper end of the base 11 near the front side of the front frame 12, the telescopic pressing and positioning device 4 is installed at the upper part of the front side of the front frame 12, the bracket 5 and the material conveying and laminating mechanism 6 are respectively installed at the upper end of the base 11, the installation height of the lower traction roller group 14 is lower than the height of the upper surface of the packaging table 3, and the installation height of the upper traction roller group 13 is higher than the height of the upper surface of the packaging table 3.

[0029] In this embodiment, the support frame 1 is reasonably designed, and the design of the front frame 12 is conducive to the good layout and installation of the ultrasonic sealing and cutting mechanism 2. At the same time, the design of the upper traction roller group 13 and the lower traction roller group 14 is conducive to the orderly transportation of the two non-woven fabric rolls, avoiding the occurrence of roll material entanglement.

[0030] As a preferred embodiment, Figure 2As shown, the ultrasonic sealing and cutting mechanism 2 includes a telescopic mechanism 21, a knife seat 22, an ultrasonic transducer 23, a horn 24 and a knife head 25. The ultrasonic transducer 23 is fixed to the lower part of the front frame 12. The horn 24 is vertically connected to the upper end of the ultrasonic transducer 23. The upper end of the horn 24 is provided with a vertical knife head 25. The blade of the knife head 25 faces upward, and the height of the blade is not higher than the height of the upper surface of the packaging table 3. The telescopic mechanism 21 is vertically assembled in the upper part of the front frame 12, with its telescopic end facing downward and drivingly connected with the knife seat 22. The lower end of the knife seat 22 is provided with a notch corresponding to the knife head 25. The telescopic mechanism 21 is used to drive the knife seat 22 to move up and down to fit or separate from the upper end of the horn 24.

[0031] In this embodiment, after the material is pushed to the packaging table 3 by the material pushing device 7 through the material conveying and laminating mechanism 6, the two non-woven fabric belts pass through the cutter head 25 and the cutter seat 22. Next, the telescopic mechanism 21 drives the cutter seat 22 to move downward until the cutter head 25 is embedded in the groove of the cutter seat 22. At this time, the two non-woven fabric bags are pressed against each other and fit together. Then, the ultrasonic transducer 23 operates to complete the packaging of the two non-woven fabric bags at the fitting part, and at the same time, the shearing is completed by the blade of the cutter head 25. The whole structural design is relatively reasonable and can quickly complete the packaging of the material stack.

[0032] The telescopic mechanism 21 may be a pneumatic cylinder or a hydraulic cylinder.

[0033] Of course, it is not limited to the above-mentioned sealing and cutting mechanism, and any other structural design that can quickly seal and cut the non-woven fabric is acceptable.

[0034] As a preferred embodiment, the telescopic pressing and positioning device 4 includes a telescopic device 41 and a horizontal pressure plate 42. The telescopic device 41 is installed on the front side of the front frame 12 through a connecting frame, and its telescopic end is vertically downward. The pressure plate 42 is horizontally arranged and assembled on the telescopic end of the telescopic device 41.

[0035] In this embodiment, when the cigarette stack wrapped in non-woven fabric passes in front of the ultrasonic sealing and cutting mechanism 2 and falls in front of the packaging table 3, the telescopic device 41 extends downward, so that the pressing plate 42 presses the cigarette stack tightly on the packaging table 3, thereby preventing the cigarettes from shifting and affecting the packaging quality when the ultrasonic sealing and cutting mechanism 2 seals and cuts the non-woven fabric on the back side of the cigarette stack.

[0036] The telescopic device 41 may be a pneumatic cylinder or a hydraulic cylinder.

[0037] As a preferred embodiment, Figure 3As shown, the material conveying and stacking mechanism 6 includes a mounting frame 61, a lifting mechanism 62, two sets of elastic telescopic components 64, two support blocks 65 and a cigarette conveying line 66. The mounting frame 61 is arranged at the upper end of the base 11 and is located between the ultrasonic sealing and cutting mechanism 2 and the bracket 5. The mounting frame 61 has two side panels spaced apart from each other, and the side panels on both sides are vertically arranged in the left-right direction. The discharge end of the cigarette conveying line 66 extends into the mounting frame 61 from any side of the mounting frame 61 in the left-right direction, and the mounting frame 61 is provided with a plurality of side panels disposed at a front-to-back interval. The side panels on both sides are vertically arranged in the left-right direction. The conveying surface contacts the bottom middle part of the cigarette strips for conveying, and the two ends of the cigarette strips are located outside the front and rear ends of the above-mentioned cigarette strip conveying line 66. The above-mentioned lifting mechanism 62 is installed in the above-mentioned mounting frame 61, and is used to lift up the cigarette strips transported to the discharge end of the above-mentioned cigarette strip conveying line 66 one by one. The front and rear side panels of the above-mentioned mounting frame 61 are respectively provided with telescopic holes at positions near the top of the above-mentioned cigarette strip conveying line 66. The two groups of the above-mentioned elastic telescopic components 64 are respectively arranged at the positions of the front and rear side panels of the above-mentioned mounting frame 61 corresponding to the above-mentioned telescopic holes. The two above-mentioned support The blocks 65 are respectively placed in the telescopic holes on both sides, and are respectively connected to the ends of the two groups of elastic telescopic components 64 that are close to each other. The lower ends of the two support blocks 65 are inclined toward the side away from the two. In the initial state, the two support blocks 65 are both extended into the mounting frame 61 and are placed above the front and rear ends of the discharge end of the cigarette conveyor line 66. When the cigarette conveyor line 66 conveys the cigarette to the discharge end, the lifting mechanism 62 lifts the cigarette and makes the two ends of the cigarette slide under the two support blocks 65. The inclined surface at the end, the two support blocks 65 are relatively far away from each other and compress the corresponding elastic telescopic components 64. After the cigarette strips have completely passed through the two support blocks 65, the two groups of elastic telescopic components 64 restore to their initial states and synchronously drive the two support blocks 65 to move closer to each other and are supported below the two ends of the cigarette strips. The upper end of the mounting frame 61 is open, and the material pushing device 7 is placed on the rear side of the upper end of the mounting frame 61, for pushing the cigarette strip stack extending from the upper end of the mounting frame 61 to the packaging table 3.

[0038] In this embodiment, the cigarettes transported through the cigarette conveyor line 66 are lifted up by the lifting mechanism 62, and the two ends of the cigarette slide through the two support blocks 65. The support blocks 65 squeeze the corresponding elastic telescopic components 64 at the same time. After the cigarette has completely slid through, the two support blocks 65 quickly move closer to each other under the deformation recovery of the elastic telescopic components 64, and are supported on the lower ends of the two ends of the cigarette. In this continuous operation, the cigarettes are stacked layer by layer in the vertical direction until the height of the stack leaks out of the upper end of the mounting frame 61 is suitable for the height of a packaged cigarette. The material pushing device 7 then pushes the stack to the packaging table 3. This design is relatively reasonable. Through the automatic resetting of the elastic telescopic components 64, the lifted cigarettes are supported and stacked layer by layer. It has a simple structure, a low failure rate and high efficiency.

[0039] It should be noted that: the above-mentioned support blocks 65 can be provided in multiple groups and arranged in parallel in the left-right direction, and the corresponding lifting mechanisms 62 can also be provided in multiple groups one by one, so that the cigarettes can be stacked up and down and in parallel in the left-right direction.

[0040] The above-mentioned elastic telescopic component 64 includes a positioning plate 641, a connecting rod 642 and a spring 643. The positioning plate 641 is fixed to the front and rear sides of the mounting frame 61. The connecting rod passes through the corresponding positioning plate 641 along the front and rear directions and is connected and fixed to the corresponding support block 65. The spring 643 is sleeved on the outside of the connecting rod 642 and is limited between the support block 65 and the positioning plate 641. When the support block 65 is squeezed outward by the end of the cigarette, it drives the connecting rod 642 to slide along the corresponding positioning plate 641 and squeezes the spring 643. After the cigarette slides past, the spring 643 restores its elastic deformation and pushes the support block 65 to drive the connecting rod 641 to move back to its position.

[0041] As a preferred embodiment, the material pushing device 7 includes a telescopic pushing mechanism 71 and a push plate 72. The telescopic pushing mechanism 71 is installed in the middle part of the bracket 5 and is located between the upper non-woven fabric roll automatic unloading mechanism 9 and the lower non-woven fabric roll automatic unloading mechanism 10. The telescopic end of the telescopic pushing mechanism 71 is horizontally forward, and the push plate 72 is vertically installed at the telescopic end of the telescopic pushing mechanism 71 along the left and right direction, and the height of the lower end thereof is not lower than the height of the upper surface of the packaging table 3 and the height of the upper end of the mounting frame 61.

[0042] In this embodiment, when pushing, the telescopic end of the telescopic pushing mechanism 71 acts on the rear end of the material stack through the push plate 72, and then extends forward to push the material stack to move, completing the pushing process. After pushing is completed, the telescopic pushing mechanism 71 returns to its original position. The overall structural design is simple, and the operation is convenient and quick.

[0043] As a preferred embodiment, the above-mentioned upper non-woven fabric roll automatic unloading mechanism 9 includes a first front roller shaft 91 and a first rear roller shaft 92 which are spaced apart from each other in the front and rear directions, and the above-mentioned first front roller shaft 91 and the first rear roller shaft 92 are respectively arranged horizontally in the left and right directions, and are rotatably installed on the upper part of the above-mentioned bracket 5, and one end of the above-mentioned first front roller shaft 91 or the first rear roller shaft 92 is connected to a first electric control driving mechanism for driving it to rotate, and a first sensor 93 for sensing whether the lower part of the non-woven fabric roll is approaching is provided at the lower part between the above-mentioned first front roller shaft 91 and the first rear roller shaft 92; the above-mentioned lower non-woven fabric roll automatic unloading mechanism 10 includes a second front roller shaft 101 and a second rear roller shaft 102 which are spaced apart from each other in the front and rear directions, and the upper The second front roller 101 and the second rear roller 102 are respectively arranged horizontally in the left and right directions, and are rotatably installed in the lower part of the above-mentioned bracket 5. One end of the above-mentioned second front roller 101 or the second rear roller 102 is connected to a second electric control drive mechanism for driving it to rotate. A second sensor 103 for sensing whether the lower part of the non-woven fabric roll is approaching is provided in the lower part between the above-mentioned second front roller 101 and the second rear roller 102; the above-mentioned first sensor 93 and the second sensor 103 are respectively connected to an alarm; the two above-mentioned non-woven fabric rolls 8 are respectively placed on the upper part between the above-mentioned first front roller 91 and the first rear roller 92 and the upper part between the above-mentioned second front roller 101 and the second rear roller 102.

[0044] It should be noted that if the nonwoven fabric is rolled up with a core, the diameter of the core should be smaller than the linear distance between the centers of the first front roller 91 and the first rear roller 92 and the second front roller 101 and the second rear roller 102 .

[0045] In this embodiment, during the unwinding process of the non-woven fabric, the diameter of the roll will become smaller and smaller, and the apex of the arc at the lower end of the non-woven fabric roll will slowly drop until the apex of the arc approaches the position of the first sensor 93 or the second sensor 10. Then, it is sensed by the first sensor 93 or the second sensor 10, and the alarm will immediately sound (sound and light alarm) to remind the staff that the non-woven fabric roll needs to be replaced.

[0046] As a preferred embodiment, the upper cache traction assembly comprises an upper gravity rod 161, an upper cache roller group 162 and an upper traction roller 163 respectively.

The upper cache roller group 162 is mounted on the upper rear side of the front frame 12 through a connecting piece and is located above the upper traction roller 163. After the non-woven fabric of the fabric roll 8 is unrolled, it passes around the upper traction roller 163 and the upper buffer roller group 162, and then passes around the upper traction roller group 13. The upper gravity rod 161 is connected to the rotation connection point with the upper support with an upper sensor sheet 164.

[0047] In this embodiment, during the normal packaging process, a non-woven fabric tape is cached between the upper cache roller group 162 and the front end of the upper gravity rod 161. When the cached fabric tape is used up, the upper gravity rod 161 will flip upward at the front end under the pull of the non-woven fabric bag, and drive the upper sensing sheet 164 to rotate to the upper sensor 165. After being sensed by the upper sensor 165, it is fed back to the controller, and the controller immediately outputs an instruction to cause the first electric control drive mechanism to run immediately to realize active unwinding. After the tape is unwound for a certain period of time and a non-woven fabric bag is cached between the upper cache roller group 162 and the front end of the upper gravity rod 161, it stops running, and so on and so forth, realizing the intermittent autonomous unwinding operation of the automatic unwinding mechanism 9 of the upper non-woven fabric roll, ensuring that the non-woven fabric used for packaging is always in the best state of unwinding (loading), so that the equipment can operate continuously and improve efficiency.

[0049] In this embodiment, during the normal packaging process, a non-woven fabric tape is cached between the lower cache roller group 172 and the rear end of the lower gravity rod 171. When the cached fabric tape is used up, the lower gravity rod 171 will flip upward at the rear end pulled by the non-woven fabric bag, and drive the lower sensing sheet to rotate to the lower sensor. After being sensed by the lower sensor, it is fed back to the controller, and the controller immediately outputs an instruction to cause the second electric control drive mechanism to run immediately to realize active unwinding.
