Description

Technical Field

[0001] The utility model relates to the technical field of hot melt adhesives, in particular to a hot melt adhesive cooling and shaping device. Background Art

[0002] Hot melt adhesive is a plastic adhesive. Within a certain temperature range, its physical state changes with the temperature, while its chemical properties remain unchanged. It is non-toxic and odorless, belonging to an environment-friendly chemical product. Because the product itself is solid, it is convenient for packaging, transportation, storage, solvent-free, pollution-free, non-toxic; and has the advantages of simple production process, high added value, large bonding strength, fast speed, etc., and is thus highly favored.

[0003] Hot melt adhesive is a solid fusible polymer without solvent and containing 100% water. It is solid at room temperature and becomes a flowing and sticky liquid when heated and melted to a certain temperature. The melted EVA hot melt adhesive is light brown or white. EVA hot melt adhesive is composed of basic resin, tackifier, viscosity regulator, antioxidant and other components.

[0004] For example, the Chinese patent publication number "CN219563878U" in the prior art provides a hot melt adhesive cooling and shaping device, including a base and a top seat. The opposite side surfaces of the base and the top seat are both fixedly connected with water tanks. The opposite side surfaces of the two water tanks are both fixedly connected with fixing plates, and grooves are opened on the opposite side surfaces of the two fixing plates.

[0005] Through the coordinated use of the base, the top seat, the water tanks, the fixing plates, the grooves, the first cooling roller, the second cooling roller, the connecting pipe, the water outlet pipe, the water inlet pipe, the drain pipe, the fixed pipe, the water pump, the water suction pipe and the refrigerator, the cooling water inside the first cooling roller and the second cooling roller can flow back into the water tank again to realize circular flow. Through the refrigerator inside the water tank, the water inside the water tank can be cooled, and at the same time, the water with temperature entering the water tank can be cooled, so as to realize the continuous cooling of the hot melt adhesive and will not reduce the cooling effect.

[0006] In the existing hot melt adhesive cooling and shaping device, only cooling water is used for cooling during cooling and shaping, and the hot melt adhesive rod cannot be quickly cooled, and the shaping speed is slow. Air cooling and water cooling are not set to cool the hot melt adhesive rod at the same time. At the same time, the hot melt adhesive rod is extruded and contacted for cooling between the two cooling rollers. When the cooling rollers rotate, they will rub the hot melt adhesive rod, resulting in the deformation of the surface of the hot melt adhesive rod that is not fully cooled and shaped, and wearing the surface of the hot melt adhesive rod, which damages the appearance of the hot melt adhesive rod. Summary of the Utility Model

[0007] The utility model aims to solve the shortcomings in the prior art that a hot melt glue stick is cooled between two cooling rollers, and the cooling rollers will rub the hot melt glue stick when rotating, resulting in deformation of the surface of the hot melt glue stick that has not been fully cooled and shaped, and wear the surface of the hot melt glue stick, thereby damaging the appearance of the hot melt glue stick, and a hot melt glue cooling and shaping device is proposed.

[0030] The rotating rod 4 is horizontally arranged above the supporting plate 1 , and the mounting plate 18 is a rectangular structure and is arranged opposite to the motor 5 .

[0031] Example 2

[0032] See also Figure 1 , Figure 2 , Figure 3 and Figure 4, A hot melt adhesive cooling and shaping device in the figure includes a support plate 1. A rotation hole 6 is opened on the surface of the support plate 1. A cooling pipe 14 passes through the inside of the rotation hole 6. One end of the cooling pipe 14 is connected to a water inlet pipe 15, and the other end of the cooling pipe 14 is connected to a water outlet pipe 16. A silica gel heat conduction sleeve 13 is pasted on the inner surface of the cooling pipe 14. A rotating pipe 12 is slidably sleeved on the inner surface of the silica gel heat conduction sleeve 13. A hot melt adhesive rod 7 is slidably placed inside the rotating pipe 12. Both ends of the cooling pipe 14 pass through the rotation holes 6 on the surfaces of the two support plates 1 respectively. A driven gear 2 is fixed on the middle surface of the cooling pipe 14. A motor 5 is installed at the top of one of the support plates 1, and a mounting plate 18 is fixed at the top of the other support plate 1. A rotating rod 4 is rotatably installed between the mounting plate 18 and the motor 5. An active gear 3 is externally installed in the middle of the surface of the rotating rod 4 and above the driven gear 2.

[0033] During the cooling and shaping process of the hot melt adhesive rod 7, the hot melt adhesive rod 7 is placed into the rotating pipe 12. At the same time, the motor 5 drives the rotating rod 4 and the active gear 3 to rotate, thereby driving the driven gear 2 to rotate through meshing transmission. Therefore, the cooling pipe 14 and the rotating pipe 12 can be driven to rotate. At the same time, the hot melt adhesive rod 7 rotates in the rotating pipe 12, and heat dissipation and temperature reduction are carried out through the cooling pipe 14, and it is cooled and shaped. Its external friction is small and the surface appearance is good.

[0034] A blowing plate 9 is fixed between the two support plates 1. A wind guiding cavity 8 is arranged in the middle of the blowing plate 9. Blowing holes 17 are opened at the top of the blowing plate 9. An air inlet pipe 10 is connected to the bottom of the blowing plate 9. A cold air blower 11 is installed at the bottom of the air inlet pipe 10.

[0035] Cooling water flows through the cooling pipe 14 through the water inlet pipe 15 and the water outlet pipe 16 to cool the hot melt adhesive rod 7 inside the rotating pipe 12 by water cooling. At the same time, the cold air blower 11 blows cold air into the wind guiding cavity 8 through the air inlet pipe 10. The cold air blows from the blowing holes 17 to the surface of the cooling pipe 14, and the heat absorbed and carried out from the hot melt adhesive rod 7 by the cooling pipe 14 is blown away, thereby indirectly cooling the hot melt adhesive rod 7 by air cooling. Therefore, the hot melt adhesive rod 7 is cooled by air cooling and water cooling at the same time, accelerating the cooling and shaping of the hot melt adhesive rod 7.

[0036] The blowing plate 9 is of a rectangular plate structure and is horizontally arranged below the cooling pipe 14. The blowing holes 17 face upward toward the surface of the cooling pipe 14.

[0037] Working mode: By rotatably installing a cooling pipe 14 between two support plates 1 and installing a rotating pipe 12 inside the cooling pipe 14 with a silica gel heat conduction sleeve 13 in between. Thus, during the cooling and shaping process of the hot melt adhesive stick 7, the hot melt adhesive stick 7 is placed into the rotating pipe 12. At the same time, the motor 5 drives the rotating rod 4 and the driving gear 3 to rotate, thereby meshing and driving the driven gear 2 to rotate. Therefore, the cooling pipe 14 and the rotating pipe 12 can be driven to rotate. At the same time, the hot melt adhesive stick 7 rotates in the rotating pipe 12 and dissipates heat through the cooling pipe 14, and is cooled and shaped. Its external friction is small and the surface appearance is good.

[0038] Fix a blowing plate 9 between two support plates 1 and set blowing holes 17 at the top of the blowing plate 9. The air guiding cavity 8 inside the blowing plate 9 is communicated with the cold air blower 11 through an air inlet pipe 10. Thus, cooling water flows through the cooling pipe 14 through a water inlet pipe 15 and a water outlet pipe 16 to cool the hot melt adhesive stick 7 inside the rotating pipe 12 by water cooling. At the same time, the cold air blower 11 blows cold air into the air guiding cavity 8 through the air inlet pipe 10, and the cold air blows from the blowing holes 17 onto the surface of the cooling pipe 14 to blow away the heat absorbed and carried out from the hot melt adhesive stick 7 by the cooling pipe 14, thereby indirectly cooling the hot melt adhesive stick 7 by air cooling. Therefore, the hot melt adhesive stick 7 is cooled by air cooling and water cooling simultaneously, accelerating the cooling and shaping of the hot melt adhesive stick 7.
