Description

Technical Field

[0001] The invention relates to the field of pressure-sensitive adhesive production, and in particular to pressure-sensitive adhesive processing equipment and a processing technology thereof for low-temperature environments. Background Art

[0002] In the synthesis process of the low-temperature pressure-sensitive adhesive production step, a variety of solid raw materials and liquid raw materials need to be added to the heating tank for synthesis treatment. However, due to the simultaneous feeding and stirring of the raw materials, the viscosity of the raw materials in the tank is high under high temperature conditions, and the solid raw materials added later have a large flow resistance in the high-viscosity raw materials in the tank. At this time, using a conventional stirring rod for stirring, it is not easy to disperse the raw materials to various areas in the tank, thereby affecting the uniformity of the distribution of the later added raw materials in the tank, resulting in the need for long-term heating and stirring of the raw materials in the tank to allow the raw materials with different content ratios to fuse together into the required low-temperature resistant pressure-sensitive adhesive. Among them, the initiator is an important reagent to promote the fusion of raw materials, but in the conventional production step, the initiator is added to the tank in a small amount by dripping. Therefore, the speed at which the initiator penetrates downward from the high-viscosity raw materials in the tank will also affect the time of raw material fusion. In addition, during the dripping of the initiator, if the initiator is unevenly dispersed, the initiator concentration in the local area of ​​the raw materials in the tank is high, while the initiator concentration in some areas is insufficient, which will affect the working cycle of the low-temperature resistant pressure-sensitive adhesive processing and the viscosity uniformity of the low-temperature resistant pressure-sensitive adhesive after synthesis. Summary of the invention

[0044] like Figure 6 , Fig.11 and Fig.12 As shown, the infusion component includes a third pipeline 301, a branch pipe 302, a slider 303, a liquid outlet nozzle 304 and a second spring 305; the third pipeline 301 is fixedly connected to the inside of the bottom shaft 7; the lower end of the third pipeline 301 is rotatably connected to the liquid inlet pipe 24; the upper side of the third pipeline 301 is rotatably connected to the inner column 8; a plurality of branch pipes 302 are connected to the upper side of the outer surface surrounding the third pipeline 301; the outer end of each branch pipe 302 is slidably connected to a slider 303; a second spring 305 is fixedly connected between each slider 303 and the branch pipe 302; a liquid outlet nozzle 304 is fixedly connected to the outer end of each slider 303; each liquid outlet nozzle 304 is closely attached to a first pipeline 102 in the rotation control component; each liquid outlet nozzle 304 is configured as a hemispherical structure; a hemispherical groove 1021 structure is provided on one side of each first pipeline 102 closely attached to the liquid outlet nozzle 304.

[0045] First, the raw materials except the initiator are slowly added into the reaction chamber 2 through the feed pipe 21, and the electromagnetic heating system 3 performs electromagnetic heating treatment on the raw materials added into the reaction chamber 2. At the same time, the output shaft of the motor 12 drives the first spur gear 13 to rotate, and the first spur gear 13 engages with the second spur gear 14 to drive the bushing 23 to rotate, and the bushing 23 drives the spline shaft 5 and the sleeve 6 to rotate, and the sleeve 6 drives the rotation control component and the angle adjustment component and the stirring drum 9 connected thereto to rotate, and the stirring drum 9 stirs the raw materials in the reaction chamber 2 so that the raw materials are heated and stirred evenly in the reaction chamber 2.

[0046] While the raw materials are poured into the reaction chamber 2 in sequence, the telescopic end of the lifting cylinder 41 pushes the fixed plate 42 to drive the sliding rod 43 to rise upward, and the sliding rod 43 pulls the fixed frame 44 to drive the spline shaft 5 and the sleeve 6 to rise upward, so that the sleeve 6 drives the rotation control component and the angle adjustment component connected thereto and the mixing drum 9 to move upward along the inner column 8, so that the mixing drum 9 is kept below the liquid level of the raw materials in the reaction chamber 2, and the newly added raw materials are kept below the stirring blade 10, so that the mixing drum 9 rises with the rising liquid level of the raw materials during the stirring period, and after the raw materials enter the mixing drum 9 of the bucket-shaped structure, the raw materials flow along the drainage block 91 to form a vortex, and while the raw materials flow out along the mixing drum 9 toward the contraction structure, the various raw materials entering the mixing drum 9 are tightly fitted due to the squeezing of the contraction structure of the mixing drum 9, thereby improving the mixing effect of the raw materials and the fusion speed between the raw materials, so as to shorten the stirring period of the raw materials, and realize that the mixing drum 9 can stir and mix the newly added raw materials with the original raw materials in the reaction chamber 2 in a semi-salvage manner in a timely manner.

[0047] During the period when the mixing drum 9 rotates and moves upward along the inner column 8, when the push rod 201 passes through the raised area of ​​the inner column 8, the upwardly moving push rod 201 is pushed into the interior of the mounting arm 101 by the inner column 8, and the push rod 201 drives the first spring 202 to be compressed inwardly, and at the same time, the push rod 201 drives the push block 203 to push the mixing drum 9 outward, so that the mixing drum 9 drives the rotating frame 103 to flip outward, and the rotating frame 103 drives the torsion spring 105 to twist and generate torque, so that the inlet of the mixing drum 9 faces the outer ring area of ​​the reaction chamber 2, and the outlet of the mixing drum 9 faces the inner ring area of ​​the reaction chamber 2, so that the mixing drum 9 can drain the raw materials located in the outer ring of the reaction chamber 2 into the inner ring during the rotation process, and when the push rod 201 passes through the annular groove 81 area of ​​the inner column 8 When the mixing drum 9 rotates, the compressed first spring 202 drives the push rod 201 to move in the opposite direction and reset along the annular groove 81 of the inner column 8, and the twisted torsion spring 105 drives the rotating frame 103 and the mixing drum 9 to rotate and reset, so that the inlet of the mixing drum 9 faces the inner circle area of ​​the reaction chamber 2, and the outlet of the mixing drum 9 faces the outer circle area of ​​the reaction chamber 2, so that the mixing drum 9 can guide the raw materials located in the outer circle of the reaction chamber 2 to the outer circle during the rotation process, so that the mixing drum 9 can mix the raw materials in the inner and outer layers of the reaction chamber 2 evenly while stirring the raw materials in a semi-salvage manner, thereby solving the problem of poor fluidity due to high viscosity of the raw materials and further improving the dispersion uniformity of various raw materials and the fusion speed between the raw materials.

[0048] After the raw materials are mixed evenly, the synthesis processing of the low-temperature resistant pressure-sensitive adhesive is started. First, the telescopic end of the lifting cylinder 41 drives the fixed plate 42 and the sliding rod 43 to move downward, and the sliding rod 43 drives the fixed frame 44 and the spline shaft 5 and the sleeve 6 to move downward, so that the sleeve 6 drives the rotation control component and the angle adjustment component connected thereto and the mixing drum 9 to reset downward along the inner column 8 until the liquid outlet nozzle 304 is realigned with the hemispherical groove 1021 of the first pipe 102, and the motor 12 continues to drive the rotation control component on the sleeve 6 and the angle adjustment component connected thereto and the mixing drum 9 to rotate, and at the same time, the sleeve 6 drives the bottom shaft 7 to rotate, and the bottom shaft 7 drives the infusion component to rotate.

[0049] Then, the initiator is poured into the liquid inlet pipe 24 through an external initiator conveying device, and the initiator enters the third pipeline 301 along the liquid inlet pipe 24, and is poured into the second liquid storage tank 1011 along the branch pipe 302, the liquid outlet nozzle 304 and the first pipeline 102. The initiator entering the second liquid storage tank 1011 is poured into the first liquid storage tank 93 along the second pipeline 104. Finally, the initiator is output from the liquid outlet pipe 92 to the raw materials entering the mixing drum 9. At this time, the raw materials are compressed in the bucket-shaped structure of the mixing drum 9, so that the output initiator can efficiently contact with the squeezed raw materials. The raw materials are then induced to fuse and the raw materials are then caught by the mixing drum 9 in a semi-salvage manner. The raw materials from various regions of the reaction chamber 2 are mixed with a small amount of initiator evenly. The processing time of the low-temperature resistant pressure-sensitive adhesive is shortened and the viscosity uniformity of the synthesized low-temperature resistant pressure-sensitive adhesive is improved. Finally, the synthesized low-temperature pressure-sensitive adhesive is discharged from the discharge pipe 22 to an external collection tank.
