Description

Technical Field

[0001] The invention relates to the technical field of cigarette card paper production, in particular to a coating process for cigarette card paper production. Background Art

[0002] Cigarette card paper is a kind of paper specially used for making cigarettes, mainly used to wrap tobacco. Its production process and material selection are very particular to meet the special needs of tobacco products.

[0003] The existing production of cigarette card paper requires a coating process on its surface. The existing coating drives the slurry through the rotation of the coating roller. The gap between the comma scraper and the coating roller is used to control the amount of slurry transfer. The roller and the coating roller rotate relative to each other to transfer the slurry to the moving cigarette card paper to form a coating. This equipment causes the slurry to be completely exposed to the air, which easily causes dust to enter the slurry, thereby affecting the coating effect and quality, causing changes in the physical properties of the slurry, and its coating consistency cannot be guaranteed. In addition, the slurry is easily left stationary for a long time, which easily causes the coating to solidify, affecting the use of the slurry. The material at the scraper mouth is very likely to absorb and agglomerate for a long time to form particles, causing coating scratches, which seriously affects the coating effect. In addition, the existing paper production process cannot achieve a high-weight effect through a coating process for low-weight paper, resulting in an increase in cost. Summary of the invention

[0004] Based on the existing coating equipment, the slurry is completely exposed to the air, which affects the coating effect and quality. The slurry is easily left standing for a long time, which easily causes the coating to solidify, affecting the use of the slurry. The material at the scraper mouth is easily absorbed and agglomerated to form particles, which cause coating scratches and seriously affect the coating effect. In addition, the existing paper production process cannot achieve the effect of high grammage by coating low-grammage paper, resulting in a technical problem of increased cost. The present invention proposes a coating process for the production of cigarette card paper.

[0005] The present invention proposes a coating process for producing cigarette card paper, which includes step 1: preparation work: after placing low-weight base paper on a hydraulic shaftless paper rack for fixing, one end of the base paper is pulled onto a coating device, and the prepared coating is added into the coating device.

[0006] Step 2: Coating work: The coating device in step 1 is used to coat the pulled base paper while conveying it.

[0008] Step 4: Deep drying: The paper dried in the infrared oven is transported to a four-section hot air oven for deep drying.

[0009] Step 5: Collection: The dried paper is cooled by a cooling fan and then rolled up by a rolling component.

[0010] Through the above technical scheme, the coating device is combined with an infrared oven and a four-section hot air oven. The infrared drying of the infrared oven can quickly heat the surface of the material, improve the drying efficiency, shorten the production cycle, and the infrared drying can be evenly irradiated on the paper to reduce hot spots and uneven drying, ensuring consistent drying effects. Due to the high heating efficiency, infrared drying is usually more energy-efficient than traditional hot air drying, which helps to reduce production costs. Infrared drying can be carried out at a lower temperature, which is suitable for temperature-sensitive materials to avoid thermal damage. Due to the fast drying speed, the leveling time of the coating can be reduced, thereby improving the surface smoothness and quality of the final product. The infrared drying process does not produce exhaust gas and is more environmentally friendly. By using infrared as the preliminary drying, the effect of improving paper coating can be achieved, and low-weight paper can achieve the effect of high-weight paper, saving costs.

DETAILED DESCRIPTION

[0051] Step 2: Coating work: The coating device in step 1 is used to coat the pulled base paper while conveying it.

[0052] Step 3: Preliminary drying: After coating is completed, the coated paper is preliminarily dried in an infrared oven.

[0053] Step 4: Deep drying: The paper dried in the infrared oven is transported to a four-section hot air oven for deep drying.

[0054] Step 5: Collection: The dried paper is cooled by a cooling fan and then rolled up by a rolling component.

[0055] The combination of coating device, infrared oven and four-section hot air oven makes low-weight paper achieve the effect of high-weight paper. Infrared drying in infrared oven can quickly heat the surface of the material, improve drying efficiency, shorten the production cycle, and infrared drying can evenly irradiate the paper to reduce hot spots and uneven drying, ensuring consistent drying effect. Due to its high heating efficiency, infrared drying is usually more energy-efficient than traditional hot air drying, which helps to reduce production costs. Infrared drying can be carried out at a lower temperature, which is suitable for temperature-sensitive materials to avoid heat damage. Due to its fast drying speed, it can reduce the leveling time of the coating, thereby improving the surface smoothness and quality of the final product. The infrared drying process does not produce exhaust gas and is more environmentally friendly. By using infrared as the initial drying, the effect of improving paper coating is achieved. Lightweight paper brings more usage area and reduces the grammage of paper. At the same time, the quality of the paper remains unchanged, achieving energy-saving, environmental protection, green and low-carbon, and cost-reducing effects.

[0057] By 195g / m 2 With 230g / m 2 The following data after testing the following paper is as follows:

[0058]

[0059]

[0060] The results show that 195g / m 2 With 230g / m 2 Both types of paper meet the testing standards, and the test results between the two are not much different, so through the coating process, the low-weight paper can achieve the effect of high-weight paper.

The rotation of the driving frame 22 drives the gear of the transmission gear set 24 on the driving frame 22 to rotate on the driving gear ring 23. The rotation of the transmission gear set 24 drives the rotating connecting rod 25 on the driving frame 22 to rotate through the gear transmission, and drives the groove sleeve 3 to rotate around the rotating point of the rotating connecting rod 25 and the driving frame 22. After the gear of the groove sleeve 3 is meshed with the rotating gear ring 31, the groove sleeve 3 is driven to rotate.

[0074] After the groove sleeve 3 rotates, the column of the lifting rod 32 slidably plugged therewith is driven to lift on the driving frame 22, and the lifting and lowering of the lifting rod 32 drives the lifting and lowering stirring paddle 33 to lift and lower, and at the same time, the lifting and lowering stirring paddle 33 is slidably plugged with the groove sleeve 3, and the rotation of the groove sleeve 3 drives the lifting and lowering stirring paddle 33 to rotate, so as to lift and rotate the paint in the stirring tank 2, and at the same time, the rotation of the rotating stirring paddle 34 stirs the paint at the center of the stirring tank 2, and after the stirring is completed, the paint enters the shunt pipe 64 through the discharge end of the stirring tank 2, and enters the corresponding conveying sleeve 6 through the shunt pipe 64;

[0075] The cigarette card is transported in the transport frame 1 through the transport component 11. The double-sided bevel gear 41 is driven to rotate by the start of the adjustment motor 4. The transmission of the double-sided bevel gear 41 drives the rotation of the adjustment screw 44. The adjustment screw 44 adjusts the height of the transport shell 46. The transmission rod 5 slides on the inner wall of the transmission bevel gear 51. The distance between the scraper 65 and the upper surface of the cigarette card is adjusted according to the coating thickness that needs to be adjusted. After the adjustment is completed, after the adjustment electromagnet 42 is energized, the double-sided bevel gear 41 is meshed with the transmission bevel gear 51 on the connecting frame 52. The rotation of the transmission bevel gear 51 drives the transmission rod 5 to rotate. The rotation of the transmission rod 5 drives the connecting transmission rod 53 to rotate through the bevel gear. The conveying gear 54 on the connecting transmission rod 53 drives the lifting piston 61 with a rack meshed therewith to descend, squeeze the coating in the conveying sleeve 6, and convey it to the cigarette card through the conveying hole 63. As the cigarette card moves, it is scraped flat by the scraper 65 to coat the surface of the cigarette card.

[0076] After the extrusion is completed, the lifting piston 61 is reset, so that the delivery hole 63 on the lifting piston 61 is connected with one end of the diversion pipe 64. After the control valve of the diversion pipe 64 is opened, it is convenient for the paint to enter the delivery sleeve 6 through the delivery hole 63, so as to facilitate the next delivery. At the same time, the lifting and lowering of the lifting piston 61 drives the connecting rod group 7 to deflect, and the connecting rod group 7 pulls the air supply pipe 71 to deflect up and down. The hot air delivered by the air supply nozzle on the lower surface of the air supply pipe 71 supplies air to the cigarette card paper to accelerate drying. The hot air delivered by the air supply nozzle on the upper surface of the air supply pipe 71 blows the hot air to the top of the conveying frame 1 to accelerate the flow of air and prevent dust from falling and entering the undried paint to affect the coating effect.
