Description

Technical Field

[0001] The present invention relates to the technical field of the preparation of butyl hot melt adhesives, and particularly relates to a continuous preparation device and a preparation method for butyl hot melt adhesives. Background Art

[0002] Butyl rubber hot melt adhesive is an adhesive, which is solid at room temperature and melts into a liquid flowing thermoplastic material when heated to a certain temperature. When melted, it is coated on the surface of the adherend, and when cooled to room temperature after lamination, the adherends are joined together, having a certain bonding strength. Butyl rubber hot melt adhesive contains 20% - 90% of polymers with reactive groups capable of forming hydrogen bonds, and has many advantages compared with thermosetting, solvent-based, and water-based adhesives, such as good melt fluidity, fast curing speed, no water and other solvents, and is widely used in fields such as packaging, printing, clothing, and electronics. Butyl rubber hot melt adhesive will not cause pollution to the surrounding environment from production to application, so it has the laudatory name of green adhesive.

[0014] The present invention includes a method for preparing a continuous preparation device for butyl hot melt adhesive, and the specific steps are as follows:

[0015] Step 1: Add various raw materials of butyl hot melt adhesive into multiple raw material boxes respectively, start the double-axis motor to drive the rotating rod and the active sprocket to rotate, thereby driving multiple driven sprockets to rotate through the chain, thereby driving the first spiral conveying rod in the raw material box to rotate and convey the raw materials into the mixing box through the conveying pipe, and then the raw materials sprayed from the conveying pipe pass through the blade in the vertical plate, the blade cuts and disperses the raw materials, and then the raw materials are contacted and mixed, and at the same time, the double-axis motor drives the pulley and the rotating shaft to rotate through the belt, thereby driving the stirring mechanism to rotate and stir the raw materials in the mixing box, thereby improving the mixing efficiency and effect of the raw materials. The stirring action of the stirring mechanism is specifically: the rotating shaft rotates to drive the U-shaped outer rod, the U-shaped movable rod and the cross rod to rotate to stir the raw materials. Since the U-shaped movable rod can move relative to the U-shaped outer rod through the elastic force of the spring, the U-shaped movable rod can always contact with the inner wall of the mixing box, thereby scraping the raw materials on the inner wall of the mixing box;

[0016] Step 2: Start the first electric push rod to drive the baffle and the sealing gasket to separate outward, and the raw materials in the mixing box fall into the vertical cylinder. At the same time, the first screw conveying rod rotates with the rotation of the rotating shaft to convey the raw materials into the horizontal cylinder. The driving motor drives the second screw conveying rod to rotate to convey the raw materials in the horizontal cylinder into the discharge pipe for extrusion molding and convey them into the box body. The molded raw materials enter the first mesh plate of the first cavity through the inlet, and enter the second cavity through the through port after molding. The second electric push rod drives the cutter to move up and down to cut the molded butyl hot melt adhesive into suitable sizes, and then convey it from the outlet to the conveyor along the material guide mesh plate, and then convey it to the next station;

[0017] Step 3: Inject cold water into the water tank through the water inlet pipe on the water tank, and the second water pump transports the cold water in the water tank into the water box and sprays it to the raw materials on the first mesh plate through the nozzle to exchange heat with the raw materials, so that the raw materials are cooled and formed into butyl hot melt adhesive. The water on the butyl hot melt adhesive falls into the bottom of the box body, and then the second water pump transports the water at the bottom of the box body into the third outer jacket to exchange heat with the raw materials inside the other end of the horizontal cylinder, so that the temperature of this part of the high-temperature molten raw materials drops, and then the water in the third outer jacket enters the second outer jacket through the first spiral tube and exchanges heat with the inside of one end of the horizontal cylinder. The raw materials are heat-exchanged to reduce the temperature of the high-temperature molten raw materials. Then the water in the second outer jacket enters the fourth outer jacket to keep the raw materials in the vertical cylinder warm. Then the water in the second outer jacket enters the first outer jacket. The heating plate in the first outer jacket heats the water, thereby heating the inside of the mixing box to form molten raw materials in the mixing box. Therefore, the temperature of the water in the box body, the third outer jacket, the second outer jacket, the fourth outer jacket and the first outer jacket gradually increases, thereby improving the heating efficiency of the water in the first outer jacket and gradually utilizing the heat.

[0018] Step 4: The hot water in the first outer jacket is transported into the shell through the second water pump. The high-temperature hot water drives the blades to rotate, and drives the fan shaft of the fan to rotate, so that the fan generates wind to dry the butyl hot melt adhesive product cut on the material guide screen. At the same time, the hot water in the shell is transported to the first outer jacket again through the pipeline, and the water vapor enters the second spiral tube through the pipeline. The flowing cold water is transported in the second spiral tube through the liquid inlet pipe and the liquid outlet pipe, so that the water vapor forms condensed water and enters the water tank. The condensed water in the water tank can be transported to the water box by the second water pump for raw material cooling and molding. The molded butyl hot melt adhesive enters the second cavity through the through port, and the cleaning brush in the through port scrapes the water on the second cavity into the bottom of the box body, so as to realize the recycling of water and the utilization of heat.

[0019] In the above technical solution, the technical effects and advantages provided by the present invention are:

[0020] 1. When the various raw material conveying pipes of the butyl hot melt adhesive of the present invention are conveyed into the mixing box, the raw materials pass through the blades in the vertical plate, the blades cut and disperse the raw materials, and then the raw materials are contacted and mixed, thereby increasing the contact area of ​​the raw materials. At the same time, the double-axis motor drives the pulley and the rotating shaft to rotate through the belt, thereby driving the stirring mechanism to rotate and stir the raw materials in the mixing box, thereby improving the efficiency and effect of raw material mixing;

[0021] 2. The U-shaped movable rod of the stirring mechanism of the present invention can move relative to the U-shaped outer rod under the elastic force of the spring, so that the U-shaped movable rod can always be in contact with the inner wall of the mixing box, thereby scraping off the raw materials on the inner wall of the mixing box to prevent excessive adhesion of the raw materials on the inner wall of the mixing box and causing waste;

[0022] 3. The present invention uses a second water pump to transport cold water in the water tank into the water box and spray it onto the raw materials on the first mesh plate through a nozzle to exchange heat with the raw materials, so that the raw materials are cooled and formed into butyl hot melt adhesive. Then, the second water pump transports the water at the bottom of the box body into the third outer jacket to exchange heat with the raw materials inside the other end of the horizontal cylinder, so that the temperature of this part of the high-temperature molten raw materials decreases. Then, the water in the third outer jacket enters the second outer jacket through the first spiral tube to exchange heat with the raw materials inside one end of the horizontal cylinder, so that the temperature of this part of the high-temperature molten raw materials decreases. Then, the water in the second outer jacket enters the fourth outer jacket to keep the raw materials inside the vertical cylinder warm. Then, the water in the second outer jacket enters the first outer jacket. The heating plate in the first outer jacket heats the water, thereby heating the inside of the mixing box, so that molten raw materials are formed inside the mixing box. Compared with the prior art, the temperature of the water in the box body, the third outer jacket, the second outer jacket, the fourth outer jacket, and the first outer jacket gradually increases, thereby improving the heating efficiency of the water in the first outer jacket. At the same time, the heat is gradually utilized, saving costs.

[0023] 4. The present invention transports the hot water in the first outer jacket into the shell through the second water pump. The high-temperature hot water drives the blades to rotate and drives the fan shaft of the fan to rotate, so that the fan generates wind to dry the butyl hot melt adhesive product cut on the material guide screen. At the same time, the hot water in the shell is transported to the first outer jacket again through the pipeline, and the water vapor enters the second spiral tube through the pipeline to form condensed water and enters the water tank. The condensed water in the water tank can be transported to the water box by the second water pump for cooling and molding of the raw materials, thereby realizing the recycling of water and the utilization of heat, saving costs.

At the same time, the dual-axis motor 12 drives the pulley 16 and the rotating shaft 15 to rotate through the belt, thereby driving the stirring mechanism 17 to rotate to stir the raw materials in the mixing box 14, thereby improving the efficiency and effect of raw material mixing;

[0050] The first electric push rod 25 is started to drive the baffle 26 and the sealing gasket 27 to separate outwards, and the raw materials in the mixing box 14 fall into the vertical cylinder 28. At the same time, the first screw conveying rod 29 rotates with the rotation of the rotating shaft 15 to convey the raw materials into the horizontal cylinder 30. The driving motor 32 drives the second screw conveying rod 31 to rotate to convey the raw materials in the horizontal cylinder 30 into the discharge pipe 33 for extrusion molding and convey them into the box body 34.

Then the water in the third outer jacket 51 enters the second outer jacket 50 through the first spiral tube 52 to exchange heat with the raw material inside one end of the horizontal cylinder 30, so that the temperature of this part of the high-temperature molten raw material decreases. Then the water in the second outer jacket 50 enters the fourth outer jacket 60 to heat the vertical The raw material inside the cylinder 28 is kept warm, and then the water in the second outer jacket 50 enters the first outer jacket 49.

At the same time, the hot water in the shell 54 is transported to the first outer jacket 49 again through the pipeline, and the water vapor enters the second spiral tube 58 through the pipeline. The second spiral tube 58 transports flowing cold water through the liquid inlet pipe and the liquid outlet pipe, so that the water vapor forms condensed water and enters the water tank 59.

Start the double-shaft motor (12) to drive the rotating rod (11) and the driving sprocket (10) to rotate, and then drive multiple driven sprockets (8) to rotate through the chain, so as to drive the first spiral conveyor rod (7) in the raw material box (6) to rotate and convey the raw materials into the mixing box (14) through the conveying pipe (13). Then the raw materials sprayed out from the conveying pipe (13) pass through the blades (20) in the vertical plate (19), and the blades (20) cut and disperse the raw materials, and then the raw materials come into contact and mix. At the same time, the double-shaft motor (12) drives the pulley (16) and the rotating shaft (15) to rotate through the belt, so as to drive the stirring mechanism (17) to rotate and stir the raw materials in the mixing box (14), improving the mixing efficiency and effect of the raw materials. The specific stirring action of the stirring mechanism (17) is: the rotating shaft (15) rotates to drive the U-shaped outer rod (21), the U-shaped movable rod (22) and the cross bar (24) to rotate and stir the raw materials.

Then the water in the third outer jacket (51) enters the second outer jacket (50) through the first spiral tube (52) and exchanges heat with the raw materials at one end of the horizontal cylinder (30). The raw materials inside are heat-exchanged, so that the temperature of this part of the high-temperature molten raw materials decreases, and then the water in the second outer jacket (50) enters the fourth outer jacket (60) to keep the raw materials inside the vertical cylinder (28) warm, and then the water in the second outer jacket (50) enters the first outer jacket (49), and the heating plate in the first outer jacket (49) heats the water, thereby heating the inside of the mixing box (14), so that molten raw materials are formed inside the mixing box (14), so that the temperature of the water in the box body (34), the third outer jacket (51), the second outer jacket (50), the fourth outer jacket (60), and the first outer jacket (49) gradually increases, thereby improving the heating efficiency of the water in the first outer jacket (49), and at the same time gradually utilizing the heat; Step 4: The hot water in the first outer jacket (49) is transported into the housing (54) through the second water pump (53).
