Description

Technical Field

[0001] The invention relates to the technical field of solvent residue control systems, in particular to an effective control system for dry composite solvent residues. Background Art

[0002] The control of residual solvent in dry composite is a crucial link in the flexible packaging industry. It is directly related to the quality and safety of the product. The oven is usually divided into multiple heating sections, and the temperature setting of each section has a direct impact on the volatilization rate of the solvent. Generally speaking, the temperature gradient will gradually increase to ensure that the solvent evaporates gradually. Good ventilation can accelerate the volatilization of the solvent in the oven and reduce the residual solvent. Different solvents have different boiling points and different volatilization rates. For example, ethyl acetate has a low boiling point and evaporates faster; while toluene has a high boiling point and evaporates slowly. The purity of the solvent will also affect its volatilization rate and residual amount. The control of residual solvent in dry composite is a systematic project, including oven temperature gradient and ventilation effect, solvent type and properties, coating amount and composite speed, substrate and ink properties, etc. By optimizing these factors, the residual solvent can be effectively reduced and the product quality and safety can be improved. At the same time, strengthening detection and monitoring and adopting new technologies and equipment are also important means to control solvent residues.

[0003] However, the existing dry composite solvent residual effective control system has the following problems in actual use:

[0004] 1. The dry composite solvent residual effective control system of the prior art uses multiple bolts to fix the hot air blower during actual use. When the hot air blower is damaged and needs to be disassembled and repaired, it takes a lot of time to disassemble and assemble multiple bolts to complete the disassembly and assembly of the hot air blower. The operation is complicated and troublesome, and it takes a lot of time;

[0005] 2. The dry composite solvent residual effective control system of the prior art cannot adjust the ventilation volume during actual use, resulting in the inability to adjust the ventilation volume required for different solvents, and the flexibility during use is poor;

[0045] The use method and advantages of the present invention: When in use, the working process is as follows:

[0046] Start the first motor 13, so that the first motor 13 drives the chute 16 to rotate through the rotating column 14 and the roller 15. Since the chute 16 is spiral and connected end to end, when the chute 16 rotates, the slider 19 can drive the slide plate 18 to slide back and forth in the horizontal direction under the limiting action of the two guide rods 17, and then the connecting rod 21 drives the fixed box 3, the clamping assembly and the hot air blower 5 to slide, so that the hot air blower 5 can evenly blow on the winding roller, thereby improving the uniformity of the temperature distribution in the oven 1;

[0047] The hot air blower 5 is placed in the middle of the bottom end of the fixed box 3 and is located between the two clamping plates 4. The knob 23 is rotated to make the knob 23 drive the screw rod 22 to rotate, thereby making the threads opposite to each other on the front and rear sides of the outer wall of the screw rod 22 generate relative thread rotation force, so that the two moving blocks 24 slide toward the middle of the inner cavity of the fixed box 3 at the same time under the limiting action of the limiting groove 27 and the limiting block 28, so that the two sliding rods 26 respectively drive the two clamping plates 4 to slide toward the middle of the bottom end of the fixed box 3 at the same time to clamp and fix the hot air blower 5, thereby realizing the installation of the hot air blower 5, solving the problem that the dry composite solvent residual effective control system of the prior art uses multiple bolts to fix the hot air blower 5 during actual use.

Under the action of the rotational force of the outer wall thread of the first screw rod 30, when the first screw rod 30 rotates, the sliding block 31 can slide along a straight line under the limiting action of the connecting block 35 and the connecting groove 34, so that the mounting rod 33 drives the movable plate 8 and the adjusting hole 9 to slide, so that the adjusting hole 9 and the ventilation hole 6 are misaligned, so that the wind flux of the ventilation hole 6 can be adjusted, which solves the problem that the dry composite solvent residual effective control system of the prior art cannot adjust the ventilation volume during actual use, resulting in that it cannot adjust the ventilation volume required for different solvents, and the flexibility during use is poor;

[0049] The third motor 36 is started to drive the second screw 37 to rotate. Under the action of the rotational force of the outer wall thread of the second screw 37, when the second screw 37 rotates, the sliding plate 39 can slide along a straight line under the limiting action of the slide rail 38, so that the connecting plate 11 drives the infrared temperature measuring instrument 12 to slide, and its measuring position can be adjusted, which solves the problem that the dry composite solvent residual effective control system in the prior art cannot adjust the detection position of the infrared temperature measuring instrument 12 during actual use, resulting in it being able to only detect the temperature of one position with a large error in the detection data.
