The driving module 6 can drive the second clamping assembly 7 to move in a direction close to or away from the first clamping assembly 3, and the second clamping assembly 7 can clamp the roll film material on the first clamping assembly 3. During the processing, the driving module 6 is first controlled to move in a direction close to the first clamping assembly 3 until the second clamping assembly 7 is connected to the first clamping assembly 3, and then the second clamping assembly 7 is controlled to clamp the roll film material on the first clamping assembly 3, and then the driving module 6 is controlled to reset, and the second clamping assembly 7 is driven to move in a direction away from the first clamping assembly 3, and the roll film material on the first clamping assembly 3 is pulled out and straightened until the second clamping assembly 7 pulls the roll film material out of a preset length.

[0032] The processing process of the film-drawing and cutting device for the outer packaging of electronic cigarettes is as follows:

[0034] The film-drawing and cutting device for the electronic cigarette outer packaging lamination can realize automatic output of the coiled film material and automatically cut the coiled film material into preset lengths through the cooperation of the film supply mechanism, the cutting mechanism and the film-drawing mechanism, without the need for manual intervention, thereby improving the automation level of the equipment, thereby reducing labor costs, and can also effectively improve processing efficiency and yield rate.

[0035] like Figure 1 , 2 As shown, the film supply mechanism includes an unwinding mechanism 8 and a roll material pulling mechanism 9, the roll material pulling mechanism 9 is fixedly connected to the substrate 1, and the roll material pulling mechanism 9 is arranged between the unwinding mechanism 8 and the cutting mechanism; the unwinding mechanism 8 is used to place the roll film material, and the roll material pulling mechanism 9 is used to pull out the roll film material on the unwinding mechanism 8 and transport it to the cutting mechanism.

[0036] like Figure 3 As shown, a fixed seat 10 is provided on the machine platform of the automatic laminating machine, and the fixed seat 10 is installed below the substrate 1. The unwinding mechanism 8 includes an unwinding box 81, and the unwinding box 81 is connected to the fixed seat 10 by a drawer; specifically, a drawer guide 82 is provided on the fixed seat 10, and the drawer guide 82 is connected to the unwinding box 81. The unwinding box 81 is slidably connected to the fixed seat 10 through the drawer guide 82, so that the unwinding box 81 is pulled out to replace the roll film material. At least two rotatable unwinding rollers 83 are provided in the unwinding box 81, and the unwinding rollers 83 are used to place the roll film material. Before processing, the unwinding box 81 is first pulled out from the fixed seat 10, and then the whole roll of the roll film material is placed on the unwinding roller 83, and then the unwinding box 81 is pushed into the fixed seat 10 to complete the installation of the roll film material; then one end of the roll film material is stretched to extend to the roll material pulling mechanism 9.

[0037] In order to limit the position of the coiled film in the unwinding box 81, a limiting mechanism is provided in the unwinding box 81, and the limiting mechanism is used to limit the coiled film on the unwinding roller 83. Specifically, the limiting mechanism includes a limiting rod 84, which is connected to the unwinding box, and two adjustment blocks 85 are provided on the limiting rod 84, and the adjustment blocks 85 are slidably limitedly connected to the limiting rod 84, and positioning rods 86 are respectively provided on the adjustment blocks 85, and the positioning rods 86 can be connected with the coiled film on the unwinding roller 83. In this embodiment, a tension knob 87 is respectively provided on each adjustment block 85, and the adjustment block 85 and the limit rod 84 can be fixed or loosened by turning the tension knob 87. Before processing, first pull out the unwinding box 81 from the fixed seat 10, then loosen the tension knob 87, so that the adjustment block 85 and the limit rod 84 are loosened, and then push the two adjustment blocks 85 to drive the positioning rod 86 to move until the distance between the two positioning rods 86 matches the width of the coiled film, and then place the coiled film on the unwinding roller 83 between the two positioning rods 86, and then tighten the tension knob 87 to connect and fix the adjustment block 85 and the limit rod 84. Through the two positioning rods 86 connected to the coiled film, the coiled film can be limited on the unwinding roller 83, avoiding axial displacement of the coiled film during processing, and improving the stability of processing. The positioning rod 83 is slidably connected to the limit rod 84 through the tension knob 87. By adjusting the distance between the two positioning rods 83, it can be applied to the processing requirements of coiled film of different widths, thereby improving the versatility of the equipment.

[0038] In order to facilitate pulling out the unwinding box 81 , a handle 88 is provided on the unwinding box 81 , and an operator can easily pull out or push back the unwinding box 81 by holding the handle 88 .

[0039] like Figure 4As shown, the coiled material pulling mechanism 9 includes a pulling frame 91 and a pulling motor 92. The pulling frame 91 is fixedly mounted on the substrate 1, and the pulling motor 92 is fixedly mounted on the pulling frame 91. The pulling frame 91 is provided with a rotatable pulling roller 93 and a tensioning roller 94. There are multiple tensioning rollers 94 for tensioning the coiled material. The output end of the pulling motor 92 is connected to the pulling roller 93, so that the pulling motor 92 can drive the pulling roller 93 to rotate on the pulling frame 91. A pressing cylinder 95 is provided on the pulling rack 91, and a rotatable pressing roller 96 is provided on the output end of the pressing cylinder 95. The pressing cylinder 95 can drive the pressing roller 96 to move towards the traction roller 93; the pressing cylinder 95 drives the pressing roller 96 to move towards the traction roller 93 until the pressing roller 96 is in contact with the rolled film on the traction roller 93, so that the pressing roller 96 and the traction roller 93 are respectively in contact with the two sides of the rolled film, so that the rotation of the traction roller 93 can pull the rolled film. Before processing, the coiled film on the unwinding roller 83 is stretched and laid on the traction roller 93, the tensioning roller 94 and the first clamping assembly 3 in sequence, and then the laminating cylinder 95 is controlled to work, driving the laminating roller 96 to move towards the traction roller 93 until the laminating roller 96 is in contact with the side of the coiled film away from the traction roller 93; during processing, by controlling the pulling motor 92 to work, the traction roller 93 can be driven to rotate, thereby pulling the coiled film to move, and the laminating roller 96 will rotate with the movement of the coiled film.

[0040] In this embodiment, there are two pressing cylinders 95, and the two pressing cylinders 95 are symmetrically installed on both sides of the pulling frame 91. The output ends of the two pressing cylinders 95 are respectively connected to the pressing rollers 96, and the pressing rollers 96 can rotate in situ on the output ends of the pressing cylinders 95. The simultaneous driving of the two pressing cylinders 95 can improve the stability of the movement of the pressing rollers 96, ensuring that they can smoothly move toward or away from the traction roller 93.

[0041] like Figure 5As shown, in this embodiment, a plurality of needle wheels 97 are sleeved on the pressing roller 96, and a plurality of convex thorns 98 are arranged in an array on the outer circumferential surface of each needle wheel 97, and the convex thorns 98 are used to punch holes in the coiled film. During the processing, the pressing cylinder 95 drives the pressing roller 96 to move in the direction close to the traction roller 93 until the needle wheels 97 on the pressing roller 96 are respectively connected with the coiled film on the traction roller 93; when the pulling motor 92 is working, the traction roller 93 rotates to drive the coiled film to move, thereby driving the needle wheel 97 and the pressing roller 96 to rotate, and the convex thorns 98 on the needle wheel 97 will pierce the coiled film, thereby opening a plurality of small holes on the coiled film. By sleeve-fitting the needle wheel 97 on the pressing roller 96 and arranging the convex thorns 98 on the needle wheel 97, it is possible to punch holes in the coiled film during processing. The roll film with small holes can better fit the outer packaging box of the electronic cigarette during lamination, which is convenient for exhaust, thereby avoiding the generation of bubbles and improving the yield rate and processing efficiency of the lamination process.

[0042] like Figure 6 , 7 As shown, the first clamping assembly 3 includes a first clamping cylinder 31, which is fixedly mounted on the cutting mounting frame 2, and a first clamping plate 32 is provided on the output end of the first clamping cylinder 31. A second clamping plate 33 is provided at a position corresponding to the first clamping plate 32 on the cutting mounting frame 2. The first clamping cylinder 31 can drive the first clamping plate 32 to move in a direction close to or away from the second clamping plate 33. Before processing, the roll film is laid on the second clamping plate 33; during processing, by controlling the first clamping cylinder 31 to work, the first clamping plate 32 can be driven to move in a direction close to the second clamping plate 33 until it is connected with the roll film on the second clamping plate 33, and the roll film is clamped by the first clamping plate 32 and the second clamping plate 33; when the second clamping assembly 7 needs to pull up the roll film, the first clamping cylinder 31 is controlled to retract, thereby driving the first clamping plate 32 to move in a direction away from the second clamping plate 33, so that it releases the roll film.

[0043] In order to limit and guide the movement direction of the first clamping plate 32, two first clamping guide rods 34 are provided on the first clamping plate 32, and the two first clamping guide rods 34 are symmetrically distributed on both sides of the first clamping cylinder 31. A first clamping guide sleeve 35 is provided at a position corresponding to the first clamping guide rod 34 on the cutting mounting frame 2, and one end of the first clamping guide rod 34 passes through the first clamping guide sleeve 35 and is slidably connected with the first clamping guide sleeve 35. When the first clamping cylinder 31 is working, the first clamping guide rod 34 will slide on the first clamping guide sleeve 35, and the movement direction of the first clamping plate 32 can be limited and guided by the cooperation between the first clamping guide rod 34 and the first clamping guide sleeve 35, so as to ensure that it can connect with the coiled film material on the second clamping plate 33, thereby clamping the coiled film material.

A third clamping plate 72 and a second clamping cylinder 73 are provided on the film-drawing mounting frame 71. A fourth clamping plate 74 is provided on the output end of the second clamping cylinder 73. The second clamping cylinder 73 can drive the third clamping plate 72 to move in a direction close to or away from the fourth clamping plate 74. In the initial state, the film-drawing mounting frame 71 and the first clamping assembly 3 are in a separated state, and the third clamping plate 72 and the fourth clamping plate 74 are also in a separated device; when the roll film material needs to be stretched, the film-drawing mounting frame 71 is driven by the driving module 6 to move in a direction close to the first clamping assembly 3 until the third clamping plate 72 is connected to the second clamping plate 33; at this time, the third clamping plate 72 is located below the roll film material, and then the second clamping cylinder 73 is controlled to work to drive the fourth clamping plate 74 to move in a direction close to the third clamping plate 72. During the movement, the fourth clamping plate 74 will contact the air on the second clamping plate 33 The rolled film materials are connected and pushed toward the third clamping plate 72 until the rolled film materials are connected to the third clamping plate 72, and the rolled film materials on the first clamping assembly 3 are clamped by the third clamping plate 72 and the fourth clamping plate 74; then the first clamping cylinder 31 is controlled to retract so that the second clamping plate 33 releases the rolled film materials; and then the driving module 6 is controlled to work and drive the film-pulling mounting frame 71 to move away from the first clamping assembly 3, and the third clamping plate 72 and the fourth clamping plate 74 will pull the rolled film materials to move together until the rolled film materials are pulled out to a preset length, completing the film-pulling process.

[0045] In order to ensure that the third clamping plate 72 and the fourth clamping plate 74 can clamp the roll film material from the first clamping component 3, a plurality of first clamping teeth 36 are provided on the first clamping plate 32 and the second clamping plate 33 at one end close to the second clamping component 7, and a plurality of second clamping teeth 75 are provided on the third clamping plate 72 and the fourth clamping plate 74 at one end close to the first clamping component 3, and the second clamping teeth 75 are staggered with the first clamping teeth 36. When the driving module 6 drives the film-pulling mounting frame 71 to move to the extreme position in the direction close to the first clamping assembly 3, the second clamping teeth 75 on the third clamping plate 72 will be inserted into the first clamping teeth 36 on the second clamping plate 33, so that the third clamping plate 72 moves to the bottom of the rolled film; when the second clamping cylinder 73 drives the fourth clamping plate 74 to move to the extreme position in the direction close to the third clamping plate 72, the second clamping teeth 75 on the fourth clamping plate 74 will be inserted into the first clamping teeth 36 on the first clamping plate 32, so that the fourth clamping plate 74 can work together with the third clamping plate 72 to clamp the rolled film on the first clamping assembly 3.

[0046] In order to limit and guide the movement direction of the fourth clamping plate 74, a second clamping guide rod 76 is provided on the fourth clamping plate 74, and a second clamping guide sleeve 77 is provided at a position corresponding to the second clamping guide rod 76 on the film-pulling mounting frame 71. The second clamping guide rod 76 passes through the second clamping guide sleeve 77 and is slidably connected with the second clamping guide sleeve 77. When the second clamping cylinder 73 is working, the second clamping guide rod 76 will slide on the second clamping guide sleeve 77. The cooperation between the second clamping guide rod 76 and the second clamping guide sleeve 77 can limit and guide the movement direction of the fourth clamping plate 74, ensuring that it can clamp the coiled film together with the third clamping plate 72.

[0047] like Fig. 9 As shown, a separation component is provided on the film-pulling mounting frame 71, and the separation component is used to peel off the two layers of the coiled film material. In this embodiment, the coiled film materials are all two-layered, and the two layers of the coiled film material are separated by the separation component, so that during the subsequent lamination, the electronic cigarette outer packaging box can be conveniently loaded between the two layers of the coiled film material to achieve rapid lamination. Specifically, the separation component includes a horizontal push cylinder 78, which is fixedly mounted on the film-pulling mounting frame 71, and a lifting cylinder 79 is provided on the output end of the horizontal push cylinder 78, and a film stripping block 710 is provided on the output end of the lifting cylinder 79. In the initial state, the horizontal push cylinder 78 is in an extended state, and the lifting cylinder 79 is in a retracted state; when working, when the second clamping assembly 7 pulls the coiled film material to a preset length, the horizontal movement cylinder is controlled to retract, and the lifting cylinder 79 and the film stripping block 710 are driven to move toward the film pulling mounting frame 71, and the film stripping block 710 is inserted into the coiled film material on the second clamping assembly 7 and inserted between the two layers of the coiled film material; then the lifting cylinder 79 is controlled to work, and the film stripping block 710 is driven to rise, so that the two layers of the coiled film material are separated, and the purpose of film stripping is achieved. Then the lifting cylinder 79 is controlled to retract, and then the horizontal movement cylinder is controlled to extend, so that the film stripping block 710 is reset to the initial position.

[0048] like Figure 8 As shown, the driving module 6 includes a driving motor 61 and a transmission belt 62. The driving motor 61 is connected to the substrate 1. A driving wheel 63 is provided on the output end of the driving motor 61. A rotatable driven wheel 64 is provided on the substrate 1. The transmission belt 62 is sleeved on the driving wheel 63 and the driven wheel 64. The film-drawing mounting frame 71 is connected to the transmission belt 62. By controlling the driving motor 61 to work, the driving wheel 63 can be driven to rotate, thereby driving the transmission belt 62 to move, and the driven wheel 64 rotates in place with the movement of the transmission belt 62; the movement of the transmission belt 62 will drive the film-drawing mounting frame 71 to move together, thereby driving the second clamping assembly 7 to move in a direction close to or away from the first clamping assembly 3.

[0049] In other embodiments, the driving module 6 may also adopt an electric cylinder or a pneumatic cylinder structure.

When the driving motor 61 is working, the film-drawing mounting frame 71 will drive the guide block 66 to slide on the guide rail 65, and the moving direction of the film-drawing mounting frame 71 is limited and guided by the cooperation of the guide block 66 and the guide rail 65, thereby improving the transmission accuracy and ensuring the stability of the processing.

[0051] like Figure 6 , 7 As shown, the fuse assembly 4 includes a fuse cylinder 41, which is fixedly mounted on the cutting mounting frame 2. A fuse frame 42 is provided on the output end of the fuse cylinder 41, and a hot melt block 43 is installed on the fuse frame 42. The hot melt block 43 is made of a material that generates heat when powered on. The fuse cylinder 41 can drive the hot melt block 43 to move in a direction close to or away from the first clamping assembly 3. When the second clamping assembly 7 stretches the coiled film material on the first clamping assembly 3 to a preset length, the first clamping assembly 3 is controlled to clamp the coiled film material again; then the support assembly 5 is controlled to support the coiled film material on the first clamping assembly 3, and then the fuse cylinder 41 is controlled to work, drive the fuse frame 42 to move, and the fuse frame 42 drives the hot melt block 43 to move in a direction close to the coiled film material until the hot melt block 43 is connected to the coiled film material on the first clamping assembly 3, and the hot melt block 43 is powered on to generate heat to fuse the coiled film material, completing the cutting process of the coiled film material.

[0052] In order to limit and guide the movement direction of the fuse rack 42, a fuse guide rod 44 is provided on the fuse rack 42, and a fuse guide sleeve 45 is provided at a position corresponding to the fuse guide rod 44 on the cutting mounting frame 2, and the fuse guide rod 44 passes through the fuse guide sleeve 45 and is slidably connected with the fuse guide sleeve 45. When the fuse cylinder 41 is working, the fuse rack 42 will drive the fuse guide rod 44 to slide in the fuse guide sleeve 45, and the movement direction of the fuse rack 42 is limited and guided by the cooperation of the fuse guide rod 44 and the fuse guide sleeve 45, ensuring that the hot melt block 43 can be connected with the coiled film material on the first clamping assembly 3, thereby improving the processing stability.

[0053] The support assembly 5 includes a support cylinder 51, which is connected to the cutting mounting frame 2. A support block 52 is provided on the output end of the support cylinder 51. The support cylinder 51 can drive the support block 52 to connect with the coiled film material on the first clamping assembly 3. In specific operation, when the second clamping assembly 7 pulls the coiled film material on the first clamping assembly 3 out to a preset length, the first clamping assembly 3 will clamp the coiled film material again; then the support cylinder 51 is controlled to work, driving the support block 52 to rise until the support block 52 is connected with the coiled film material on the first clamping assembly 3, supporting the coiled film material, and then the fuse cylinder 41 is controlled to work, driving the hot melt block 43 to descend to fuse the coiled film material.

[0054] In order to limit and guide the movement direction of the support block 52, a support guide rod 53 is provided on the support block 52, and a support guide sleeve 54 is provided at a position corresponding to the support guide rod 53 on the cutting mounting frame 2, and the support guide rod 53 passes through the support guide sleeve 54 and is slidably connected with the support guide sleeve 54. When the support cylinder 51 is working, the support block 52 will drive the support guide rod 53 to slide in the support guide sleeve 54, so that the support block 52 can move smoothly until it is connected with the coiled film material on the first clamping assembly 3, thereby improving the accuracy and stability of the transmission.

[0055] The film-drawing and cutting device for the outer packaging coating of electronic cigarettes can realize the precise pulling of the coiled film material to a preset length through the cooperation of the first clamping component 3, the second clamping component 7 and the driving module 6, and the length pulled out each time is the same; and then through the cooperation of the fuse component 4 and the support component 5, the coiled film material can be fused without manual operation, which can effectively improve the processing efficiency.

[0056] Through the cooperation of the unwinding mechanism 8 and the coil pulling mechanism 9, the coiled film material can be output to the first clamping assembly 3 to realize automatic feeding without manual pulling; and by adjusting the position of the two positioning rods 86 on the unwinding roller 83, it can be suitable for coiled film materials of different widths, thereby improving the versatility of processing.

The scope of the present utility model includes but is not limited to the specific implementation mode. All equivalent changes made in accordance with the present utility model are within the protection scope of the present utility model.
