Description

Technical Field

[0001] The invention relates to the technical field of transfer paper compounding and back coating, and in particular to a transfer paper device having both compounding and back coating functions. Background Art

[0002] Back coating is a protective coating on the back of the base paper to prevent the adhesive around the label from adhering to the base paper after waste discharge and rewinding. Back coating not only solves the problem of defects on the back of the paper, but also improves the performance of the paper, thereby improving product quality.

[0003] Patent number CN211420718U discloses a back coating device for tipping paper, including a drying component, a printing component and a reversing roller group; wherein the drying component is used to dry the tipping paper; the printing component is arranged below the drying component, and the printing component includes a printing roller, which is used to print the tipping paper; the reversing roller group is arranged on the drying component, and the tipping paper bypasses the reversing roller group, and the back of the tipping paper abuts against the printing roller and enters the printing component. The device can reverse the tipping paper and print the solvent on the back of the tipping paper. By printing the solvent on the back (i.e. the back) of the tipping paper, the difference in the characteristics of the front and back of the tipping paper can be greatly reduced, and the "curling" and "curling" of the tipping paper can be eliminated, and the "warping" of the tipping paper, "leakage" of cigarettes, "turning" and other situations can be avoided.

[0004] It is difficult for the above-mentioned device to add back coating liquid into the solvent box in time during the back coating process. After working for a long time, the amount of back coating liquid in the solvent box decreases, and it is difficult for the printing roller to be contaminated with a sufficient amount of back coating liquid for back coating, which affects the back coating effect. In addition, the paper is not cleaned before back coating. If there are impurities such as paper scraps or dust remaining on the paper surface, it will also affect the back coating effect.

DETAILED DESCRIPTION

[0027] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0028] Example 1: A transfer paper device having both laminating and back coating functions, such as Figure 1-Figure 8 As shown, the fixed frame 1 includes a first storage roller 101, a second storage roller 102, a guide roller 103, a guide belt transmission member 104, a guide transmission gear 106, a receiving roller 107, a compounding mechanism and a back coating mechanism. The first storage roller 101 and the second storage roller 102 are installed on the fixed frame 1. The first storage roller 101 and the second storage roller 102 are respectively placed on the paper to be compounded. The fixed frame 1 is rotatably connected with the guide roller 103. The two guide rollers 103 are fixedly connected with the guide transmission gear 106. The first storage roller 101 and the second storage roller 102 are respectively placed on the paper to be compounded. 101 is connected to the guide roller 103 through the guide belt transmission member 104. The first storage roller 101 drives the guide roller 103 to rotate through the guide belt transmission member 104. Under the action of the guide transmission gear 106, the two guide rollers 103 rotate towards each other and provide guidance for the paper to be composited. A receiving roller 107 is rotatably connected in the fixed frame 1. The composite mechanism is installed in the fixed frame 1. The composite mechanism presses the two papers together. The back coating mechanism is installed on the top of the fixed frame 1. The back coating mechanism applies back coating liquid to the back of the composited paper.

[0029] The two rolls of paper to be compounded are respectively put on the first storage roller 101 and the second storage roller 102, and then the paper passes through the middle of the two guide rollers 103, and then the paper passes through the middle of the compounding mechanism and the back coating mechanism, and finally is wound on the receiving roller 107, and then the equipment is started, and the receiving roller 107 rotates to pull the paper to be compounded out from the first storage roller 101 and the second storage roller 102. When the paper bypasses the guide roller 103 and enters the compounding mechanism, the compounding mechanism starts and presses the two layers of paper together. The compounded paper after pressing continues to move in the fixed frame 1. When the compounded paper passes through the back coating mechanism, the back coating mechanism coats the back coating liquid on the back of the compounded paper, and finally the compounded paper coated with the back coating liquid is rolled outside the receiving roller 107.

[0030] Embodiment 2: Based on embodiment 1, Figure 1-Figure 3 As shown, the compounding mechanism includes a compound belt transmission member 105, a heating roller 2, a heating wire 201, a hot pressing roller 202, a fixed guide plate 3 and a distance adjustment component. The hot pressing roller 202 is rotatably connected in the fixed frame 1, and the second storage roller 102 is connected to the hot pressing roller 202 through the compound belt transmission member 105. The second storage roller 102 drives the hot pressing roller 202 to rotate through the compound belt transmission member 105. The fixed frame 1 is fixedly connected with a fixed guide plate 3, and a heating roller 2 is arranged in the fixed guide plate 3. The heating wire 201 is installed in the heating roller 2. When the paper passes between the heating roller 2 and the hot pressing roller 202, the heating wire 201 heats the paper, and then the paper is compounded together under the pressing action of the hot pressing roller 202 and the heating roller 2. The distance adjustment component is installed on the fixed guide plate 3, and the distance adjustment component is used to adjust the distance between the heating roller 2 and the hot pressing roller 202, so as to perform hot pressing compounding on the paper under different conditions.

[0031] like Figure 1 and Figure 2 As shown, the distance adjustment component includes a positioning cylinder 301, a fixed guide rod 302 and a sliding block 303. The positioning cylinder 301 is installed on the fixed guide plate 3, the fixed guide rod 302 is fixedly connected to the fixed guide plate 3, the sliding block 303 is slidably connected to the fixed guide rod 302, the telescopic rod of the positioning cylinder 301 is connected to the sliding block 303, the two ends of the heating roller 2 are rotatably connected in the sliding block 303, the positioning cylinder 301 drives the heating roller 2 to move through the sliding block 303 to adjust the distance between the heating roller 2 and the hot pressing roller 202 and change the composite environment.

[0032] When the paper continues to move around the guide roller 103, it will enter between the heating roller 2 and the hot pressing roller 202. The positioning cylinder 301 drives the sliding block 303 to slide along the fixed guide rod 302, and then adjusts the heating roller 2 to move toward the hot pressing roller 202, so that the heating roller 2 and the hot pressing roller 202 press the paper together. When the second storage roller 102 rotates, the hot pressing roller 202 is driven to rotate through the composite belt transmission member 105. The heating wire 201 heats the paper through the heating roller 2, and under the squeezing of the heating wire 201 and the hot pressing roller 202, the paper is pressed together. When different papers are laminated, the thickness of the laminated papers is different. The positioning cylinder 301 can adjust the distance between the heating roller 2 and the hot pressing roller 202 through the sliding block 303 to perform hot pressing lamination on different papers.

[0033] like Figure 3-Figure 6 As shown, the back coating mechanism includes a back coating liquid storage cylinder 5, a liquid guide tube 501, an L-shaped liquid delivery tube 502, a rotating chassis 503, a fixed cylinder 504, a top outlet 5041, a rotating disk 505, a receiving tube 506, a rotating coating block 507, a rotating pressure roller 701 and a back coating belt transmission member 702. The fixed frame 1 is fixedly connected with the back coating liquid storage cylinder 5. The back coating liquid storage cylinder 5 is divided into two layers. The upper layer of the back coating liquid storage cylinder 5 is used to store the back coating liquid. A liquid guide tube 501 is fixedly connected to the bottom outlet of the upper layer of the back coating liquid storage cylinder 5, a rotating chassis 503 is rotatably connected in the back coating liquid storage cylinder 5, the bottom surface of the liquid guide tube 501 is in contact with the top surface of the rotating chassis 503, an L-shaped liquid delivery tube 502 is slidably connected in the rotating chassis 503, a rotating roller 701 is rotatably connected to the fixed frame 1, a fixed cylinder 504 is fixedly connected in the fixed frame 1, and both ends of the fixed cylinder 504 are rotatably connected to rotating disks 505 , the rotating pressure roller 701 is connected to the rotating disk 505 through the back coating belt transmission part 702, and the rotating pressure roller 701 drives the rotating disk 505 to rotate through the back coating belt transmission part 702. A receiving tube 506 is fixedly connected to the rotating disk 505, and the receiving tube 506 passes through the rotating disk 505 and is connected to the fixed cylinder 504. A rotating smear block 507 is fixedly connected to the rotating disk 505, and the rotating smear block 507 is rotatably connected to the fixed cylinder 504. The L-shaped liquid feeding tube 502 is slidably connected to the receiving tube 506. When the L-shaped liquid feeding tube 502 rotates to the lowest point with the rotating disk 505, the top of the L-shaped liquid feeding tube 502 will slide downward along the rotating chassis 503 to the lowest point and be connected to the bottom of the liquid guide tube 501. At this time, the back coating liquid storage cylinder 5, the liquid guide tube 501, the L-shaped liquid feeding tube 502, the receiving tube 506 and the fixed cylinder 504 are connected, and the back coating liquid in the back coating liquid storage cylinder 5 flows into the fixed cylinder 504.

[0034] The laminated paper continues to move and passes between the rotating pressure roller 701 and the fixed cylinder 504. The gap in the fixed cylinder 504 is divided into three parts by the rotating coating block 507. Each part of the space is connected to a receiving tube 506 on the rotating disk 505. During the back coating process, the rotating pressure roller 701 is driven by an external motor to rotate. When the rotating pressure roller 701 rotates, it can drive the rotating disk 505 to rotate through the back coating belt transmission member 702. When the rotating disk 505 rotates, it drives the L-shaped liquid delivery tube 502 to move up and down through the receiving tube 506. The top of the L-shaped liquid delivery tube 502 is slidably connected to the rotating chassis 503. When the height of the L-shaped liquid delivery tube 502 decreases, the vertical pipe of the L-shaped liquid delivery tube 502 will drive the rotating chassis 503 to rotate in the horizontal direction. At the same time, the L-shaped liquid delivery tube 502 will slide outward along the receiving tube 506. When the L-shaped liquid delivery tube 502 drops to the lowest point, the top inlet of the L-shaped liquid delivery tube 502 just rotates with the rotating chassis 503 to the bottom outlet of the liquid guide tube 501, and the back coating liquid in the back coating liquid storage cylinder 5 will enter the liquid guide tube 501. Under normal conditions, the bottom of the liquid guide tube 501 is rotated. The bottom plate 503 is blocked, and the back coating liquid in the liquid guide tube 501 will not continue to flow downward. When the top inlet of the L-shaped liquid delivery tube 502 rotates with the rotating bottom plate 503 to the bottom outlet of the liquid delivery tube 501, the back coating liquid can flow into the fixed cylinder 504 along the liquid delivery tube 501, the L-shaped liquid delivery tube 502 and the receiving tube 506. When the height of the L-shaped liquid delivery tube 502 rises, the L-shaped liquid delivery tube 502 is out of contact with the liquid delivery tube 501, and the back coating liquid will no longer flow into the fixed cylinder 504, so as to prevent the back coating liquid from overflowing from the fixed cylinder 504. The L-shaped liquid delivery tube 502 rises When the rotating disk 505 rotates, it can drive the rotating smearing block 507 to rotate. When the rotating smearing block 507 rotates, it will drive the back coating liquid in the fixed cylinder 504 to move. During the rotation of the rotating smearing block 507, the back coating liquid will be pushed out from the top outlet 5041 of the fixed frame, and then the back coating liquid will be smeared on the back of the composite paper. During the rotation of the rotating disk 505, when the L-shaped liquid feeding tube 502 drops to the lowest point, the back coating liquid consumed in the corresponding internal cavity of the fixed cylinder 504 will be replenished to continue the back coating operation.

[0035] Embodiment 3: Based on embodiment 2, Figure 6As shown, it also includes a flattening roller 6, a recycling frame 601, a recycling roller 602 and a smoothing guide roller 603. The flattening roller 6 is rotatably connected in the fixed frame 1. When the composite paper coated with the back coating liquid passes through the flattening roller 6, the back coating liquid on the back side of the composite paper is spread by the flattening roller 6. The recycling frame 601 is fixedly connected in the fixed frame 1. The recycling roller 602 is rotatably connected to the recycling frame 601. The recycling roller 602 is attached to the back side of the composite paper. When the composite paper passes through the recycling roller 602, the excess back coating liquid on the back side of the composite paper is blocked by the recycling roller 602. The excess back coating liquid falls into the recovery frame 601, and the back coating liquid in the recovery frame 601 contacts the flattening roller 6. The flattening roller 6 contacts the back side of the composite paper during rotation, so as to apply the recovered back coating liquid on the back side of the composite paper. A smoothing guide roller 603 is rotatably connected in the fixed frame 1, and the composite paper bypasses the smoothing guide roller 603 and is rolled downward outside the receiving roller 107. When the composite paper passes through the smoothing guide roller 603, it will adhere to the outside of the smoothing guide roller 603. Under the action of the smoothing guide roller 603, the back coating liquid on the back side of the composite paper is evenly coated.

[0036] After the back coating liquid is coated on the composite paper, the composite paper continues to move and passes through the flattening roller 6. The flattening roller 6 will spread the back coating liquid on the back of the composite paper. When the composite paper continues to move and passes through the recovery roller 602, the excess back coating liquid on the back of the composite paper will be blocked by the recovery roller 602, and the excess back coating liquid will fall into the recovery frame 601. The back coating liquid entering the recovery frame 601 will contact the flattening roller 6, and as the flattening roller 6 rotates, the back coating liquid in the recovery frame 601 will be smeared on the back of the composite paper by the flattening roller 6, so as to achieve the function of recycling and reuse. After the composite paper passes through the recovery roller 602, the composite paper will bypass the smoothing guide roller 603 and wrap around the receiving roller 107. When the composite paper passes through the smoothing guide roller 603, it will be close to the surface of the smoothing guide roller 603. With the cooperation of the flattening roller 6, the recovery roller 602 and the smoothing guide roller 603, the back coating liquid on the back of the composite paper is evenly smeared.

[0037] like Figure 3 As shown, it also includes a cleaning frame 4, a cleaning belt transmission member 401 and a cleaning shaft 402. The cleaning frame 4 is fixedly connected to the fixed frame 1, and the cleaning shaft 402 is rotatably connected to the cleaning frame 4. Two cleaning shafts 402 are provided, and the two cleaning shafts 402 are connected by a cleaning belt transmission member 401. The two cleaning shafts 402 are respectively located on the upper and lower sides of the composite paper.

[0038] After being hot-pressed and laminated by the laminating mechanism, the paper will pass through the middle of the cleaning frame 4. When the cleaning shaft 402 in the cleaning frame 4 rotates, it will sweep away the debris on the upper and lower surfaces of the composite paper to clean the upper and lower surfaces of the composite paper.

[0039] like Figure 6 and Figure 7As shown, it also includes an ink frame 7, a printing roller 703 and a printing transmission gear 704. The fixed frame 1 is fixedly connected with the ink frame 7, and the ink frame 7 is used to store printing ink. The printing roller 703 is rotatably connected in the fixed frame 1. An opening is provided on the bottom surface of the ink frame 7 close to the printing roller 703, and the opening of the ink frame 7 is completely fitted with the printing roller 703 to prevent the printing ink from leaking from the opening of the ink frame 7. The printing transmission gear 704 is fixedly connected to the printing roller 703 and the rotating pressure roller 701. The rotating pressure roller 701 drives the printing roller 703 to rotate through the printing transmission gear 704. When the printing roller 703 rotates, the printing ink in the ink frame 7 is brought out and printed on the composite paper. During the printing process, the flattening roller 6 provides support from the bottom surface of the composite paper.

[0040] After the composite paper passes through the rotating pressure roller 701, it passes between the printing roller 703 and the flattening roller 6. When the rotating pressure roller 701 rotates, the printing roller 703 is driven to rotate through the printing transmission gear 704. When the printing roller 703 rotates, the printing ink in the ink frame 7 is brought out. As the printing roller 703 continues to rotate, the printing roller 703 prints the corresponding label on the surface of the composite paper.

[0041] like Figure 6 and Figure 8 As shown, it also includes a drying box 8 and a heating tube 801. The drying box 8 is fixedly connected to the fixed frame 1, and the heating tube 801 is fixedly connected to the drying box 8. When the composite paper passes through the drying box 8, the heating tube 801 dries the back coating liquid on the composite paper; after the back coating liquid on the back of the composite paper is evenly coated, it passes through the drying box 8, and the heating tube 801 in the drying box 8 dries the back coating liquid on the back of the composite paper.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
