Description

[0002] Tipping paper, also known as "tipping paper", is mainly used to wrap cigarette filters. This paper is made from tipping paper through printing, hot stamping, printing specific brand patterns, and laser punching technology. The air permeability design on the tipping paper has many advantages, such as regulating the burning speed of tobacco, stabilizing smoke, reducing tar content, and improving the hygiene and safety of tobacco products.

DETAILED DESCRIPTION

[0042] Embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0043] like Figure 1-Figure 2 As shown, a laser punching device 2 for cigarette tipping paper comprises a frame 1 and a punching device 2, a preheating assembly 11, a lifting and lowering temperature control mechanism 3 and a cooling assembly 12 arranged on the frame 1. A conveying roller assembly 10 is arranged on the frame 1, and the conveying roller assembly 10 is used to convey the tipping paper. The punching device 2 is used to perform laser punching on the tipping paper. The preheating assembly 11 is arranged at the paper inlet of the punching device 2, and the preheating assembly 11 is used to preheat the tipping paper. The cooling assembly 12 is arranged at the paper outlet of the punching device 2 and connected to the preheating assembly 11, and the cooling assembly 12 is used to cool the tipping paper. The lifting and lowering temperature control mechanism 3 is arranged below the punching device 2, and the lifting and lowering temperature control mechanism is used to maintain the temperature when the tipping paper is punched. The present invention can preheat the tipping paper before punching through the preheating assembly 11, and the temperature of the tipping paper during the punching process is kept warm in real time through the lifting and lowering temperature control mechanism 3, and the cooling assembly 12 is used to prevent the tipping paper from suddenly cooling down after punching, which causes thermal stress changes.

[0044] The punching device 2 is a laser punching device. This structure is a prior art in this industry and will not be elaborated in this application.

[0045] like Figure 3As shown, the lifting and lowering temperature control mechanism 3 includes a support seat 31, a cam driving component 32, an auxiliary component 33 and a synchronous connecting plate 34. The support seat 31 is fixedly connected to the frame 1. The cam driving component 32 passes through the frame 1 and abuts against the synchronous connecting plate 34. One end of the auxiliary component 33 is fixedly connected to the support seat 31, and the other end is connected to the synchronous connecting plate 34. The synchronous connecting plate 34 is located below the tipping paper. The cam driving component 32 drives the synchronous connecting plate 34 to approach / move away from the tipping paper. The present invention drives the synchronous connecting plate 34 to approach the tipping paper through the cam driving component 32, providing stable heat support for the tipping paper during laser drilling, so that the consistency of the paper temperature of the tipping paper during laser drilling helps to improve the accuracy of drilling, thereby improving the quality of the tipping paper. Moreover, the cam driving component 32 can quickly drive the synchronous connecting plate 34 to approach or move away from the tipping paper, and can quickly adjust the position of the synchronous connecting plate 34, reducing the time loss during the conversion process, which helps to improve the overall production efficiency.

[0046] The synchronous connecting plate 34 includes a plate body 341 and a temperature control component 342. The plate body 341 is fixedly connected to the auxiliary component 33. Long temperature control grooves are provided on both sides of the plate body 341. One end of the temperature control component 342 is connected to the long temperature control groove, and the other end is connected to the preheating component 11. The long temperature control groove is located below the edge of the tipping paper. A temperature measuring device is provided on the plate body 341.

[0047] During the laser drilling process, the laser will generate high-energy beams that focus on the surface of the material and achieve drilling by instantly melting or vaporizing the material at high temperature. This high temperature change may change the fiber structure of the tipping paper, making the edge part fragile and easy to break, which in turn causes the edge of the tipping paper to be burned or damaged by heat. The present application can ensure the consistency of the paper temperature of the tipping paper during laser drilling through the temperature control component 342, avoiding the problem of tipping paper being burned or damaged due to the accumulation of thermal stress caused by rapid thermal changes.

[0048] See also Figure 3The cam driving assembly 32 includes a transmission roller 321, a cam 322, an abutting wheel 323, a connecting seat 324 and a driving device. The transmission roller 321 passes through the frame 1 and is fixedly connected to the cam 322. The abutting wheel 323 abuts against the cam 322. The abutting wheel 323 is connected to the connecting seat 324. The connecting seat 324 is fixedly connected to the synchronous connecting plate 34. The driving device is arranged in the frame 1 and connected to the transmission roller 321. The present invention realizes stable support for the temperature control component 342 during the laser punching process by adopting the cam driving assembly 32. The precise matching of the cam 322 and the abutting wheel 323, as well as the real-time detection of the temperature measuring device, ensures the stability of the tipping paper under the action of the laser, and can adjust the rotation of the transmission roller 321 in real time to make the synchronous connecting plate 34 in a suitable position to avoid the temperature instability of the tipping paper. At the same time, the cam driving assembly 32 is easy to be integrated into the existing production line, simple to operate, convenient to maintain, and does not require complicated adjustment and calibration.

[0049] The transmission roller 321 passes through the frame 1 and is connected to the driving device (not shown in the figure). This structure is a prior art and will not be described in detail in this application.

[0050] Furthermore, the cam driving assembly 32 further includes an adjusting member 325, on which a notch is provided, and the adjusting member 325 is fixedly connected to the connecting seat 324; the synchronous connecting plate 34 further includes a connecting rod 343, one end of which is fixedly connected to the plate body 341, and the other end of which is movably connected to the adjusting member 325. The present invention can adjust the position of the synchronous connecting plate 34 through the cooperation between the adjusting member 325 and the connecting rod 343, and can be adjusted according to the thickness of the tipping paper, which is more practical.

[0051] Furthermore, the auxiliary component 33 includes a slide 331, a linear bearing 332 and a slide rod 333. The slide 331 is fixedly connected to the plate body 341, the linear bearing 332 passes through the slide 331 and is fixedly connected to the slide 331, and the slide rod 333 passes through the linear bearing 332 and is fixedly connected to the support seat 31. The auxiliary component 33 can provide continuous and stable support for the cam drive component 32 to drive the synchronous connection plate 34 to move up and down, and this dynamic support reduces the vibration and displacement of the temperature control component 342.

[0052] like Figure 4-Figure 5As shown, the temperature control component 342 includes an air pump 3421, an air nozzle 3422 and a slot plate 3423. The air pump 3421 is connected to the air nozzle 3422 through an air pipe. The air nozzle 3422 is connected to the temperature control slot 3411. The inside of the air nozzle 3422 and the temperature control slot 3411 are both trumpet-shaped, wide at the top and narrow at the bottom. The plate body 341 is also provided with a placement slot 3412, which is arranged at the temperature control slot 3411. The slot plate 3423 is in the placement slot 3412 and above the temperature control slot 3411. The slot plate 3423 is provided with a plurality of slots, and the slot plate 3423 is below the edge of the tipping paper. The present invention significantly improves the stability of the tipping paper during the laser drilling process by using the temperature control component 342, that is, the combination of the air pump 3421, the air nozzle 3422 and the slot plate 3423. The trumpet-shaped design of the air nozzle 3422 and the temperature control slot 3411 effectively enhances the temperature transfer to the paper. The narrow area at the lower end is convenient for the air pipe connection, and the wide area at the upper end is relatively open, which can make the warm air flow more diffuse and increase the temperature control area. At the same time, the grooves on the groove plate 3423 can separate the warm air into multiple flow states. Combined with the width, depth and angle of the groove, it plays a role in finely regulating the airflow distribution, realizing precise control of the airflow and improving the insulation effect.

[0053] See also Figure 2 The conveying roller assembly 10 includes an inlet and outlet feeding roller 101, an inlet and outlet active roller 102, an adjustment roller assembly 103 and a tension roller 104 arranged on the frame 1. The adjustment roller assembly 103 includes an adjustment shaft 1031, an extension plate 1032 and an adjustment roller 1033. The adjustment shaft 1031 is connected to the frame 1. One end of the extension plate 1032 is arranged at the diagonal of the adjustment shaft 1031. The adjustment roller 1033 is arranged at the other end of the extension plate 1032. The inlet and outlet feeding roller 101 is used to feed the tipping paper, the inlet and outlet active roller 102 is used to pull the tipping paper, the adjustment rotation is used to drive the adjustment roller 1033 to rotate clockwise / counterclockwise, and the tension roller 104 is used to detect the tipping paper tension. The present invention significantly improves the stability of the tipping paper during the laser punching process through the optimized design of the conveying roller assembly 10. The coordinated work of the in-and-out feeding roller 101 and the in-and-out driving roller 102 ensures the smooth feeding and precise pulling of the tipping paper. The introduction of the adjusting roller assembly 103 effectively adjusts the tension of the tipping paper by adjusting the rotating shaft 1031 to drive the adjusting roller 1033 to rotate clockwise / counterclockwise, avoiding the shaking and displacement during the punching process, and improving the accuracy and efficiency of the punching. The setting of the tension roller 104 can monitor the tension changes of the tipping paper in real time, make timely adjustments, reduce the damage of the tipping paper caused by uneven tension, and reduce material costs.

[0054] The inlet and outlet feeding rollers 101, the inlet and outlet active rollers 102 and the adjusting shaft 1031 of the present application all pass through the frame 1 and are connected to the driving device (not shown in the figure), and the tension roller 104 detects the tension in real time. These are all prior arts and will not be elaborated in this application.

[0055] During the laser drilling process, the tipping paper is heated and cooled rapidly due to the concentrated laser energy. This rapid heating and cooling process will generate thermal stress inside the material. Thermal stress will affect the integrity of the material and the possibility of cracking in the later processing. Therefore, further, such as Figure 2 , Figure 6 As shown, the present invention is provided with a preheating component 11, and the preheating component 11 includes a preheating chamber 111 and a heating element 112. The preheating chamber 111 is fixedly connected to the extension plate 1032, and the opening of the preheating chamber 111 faces the lower side of the plugging paper. The heating element 112 is in the preheating chamber 111, and a plurality of fan blades 113 are arranged at intervals at the opening of the preheating chamber 111. An air inlet 1111 is arranged on the lower side of the preheating chamber 111. The introduction of the preheating component 11 of the present invention effectively reduces the thermal stress of the material caused by the temperature difference, reduces the damage of the plugging paper during the laser drilling process, reduces the quality problems such as irregular hole edges, changes in hole size and shape, and cracking, and improves the smoothness of the production process. In addition, by reducing material waste and equipment loss, the present application helps to achieve green production and conforms to the concept of sustainable development.

[0056] When the preheating assembly 11 is used, the heating element 112 is first heated, and the heating element 112 can be an electric heating tube or other equipment. Secondly, the air inlet 1111 at the bottom of the preheating chamber 111 is ventilated to generate a hot air flow. Since the preheating chamber 111 has only one side open and the opening is facing the tipping paper, the hot air flow will blow toward the tipping paper for heating. A temperature sensor (not shown in the figure) can be set on the other side of the tipping paper for real-time detection to ensure the accuracy of preheating.

[0057] Further, if Figure 2 , Figure 7As shown, the cooling component 12 of the present invention includes a temperature barrel 121, a mixing tube 122, a fan 123 and a cooling chamber 124. The temperature barrel 121 is between the heating element 112 and the fan 113. The inlet of the temperature barrel 121 is connected to the air outlet of the vacuum pump 3421. The outlet of the temperature barrel 121 is connected to one end of the mixing tube 122. The other end of the mixing tube 122 is connected to the fan 123. The fan 123 is connected to the cooling chamber 124. The outlet of the cooling chamber 124 faces the tipping paper. The cooling component 12 of the present invention can extract the air passing through the heating element 112 into the cooling chamber 124 through the temperature barrel 121 through the fan 123 to slowly cool the tipping paper after punching, further alleviate the internal thermal stress of the material caused by rapid heating and cooling, and ensure that the tipping paper after punching can be quickly stabilized. The present invention utilizes the temperature cylinder 121 and the heating element 112 for heating, thereby improving the utilization rate of the equipment and being more in line with the concept of environmental protection and energy saving; and after the hot air is transported to the cooling chamber 124 through the fan 123, its temperature will also drop slightly, which is also convenient for the rapid stabilization and slow cooling of the tipping paper, and preventing the sudden drop in temperature from affecting the performance of the tipping paper.

[0058] like Figure 8 As shown, a hot air inlet pipe 1221 and an air inlet slot 1222 are provided at one end of the mixing tube 122 away from the fan 123. The hot air inlet pipe 1221 is connected to the outlet of the temperature cylinder 121, and the air inlet slot 1222 is provided on the wall surface of the mixing tube 122. The mixing tube 122 achieves precise mixing of hot air and cooling air by introducing the hot air inlet pipe 1221 and the air inlet slot 1222. This solution can quickly adjust the air flow temperature, ensure that the cooling process of the tipping paper after laser drilling is both rapid and gentle, improve the cooling efficiency, and reduce the energy consumption of the equipment.
