Description

Technical Field

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

[0002] Hot melt adhesive is a plastic adhesive. Its physical state changes with temperature within a certain temperature range, while its chemical properties remain unchanged. It is non-toxic and odorless, and is an environmentally friendly chemical product. Because the product itself is solid, it is easy to package, transport, and store, and is solvent-free, pollution-free, and non-toxic. It is also popular for its simple production process, high added value, high bonding strength, and fast speed. The basic resin of hot melt adhesive is ethylene and vinyl acetate copolymerized under high temperature and high pressure. After the hot melt adhesive raw material is made into a solid hot melt adhesive substance, it needs to be cooled.

[0003] For example, a hot melt adhesive cooling device with application number CN202321777522.3 includes a box body, a conveying structure for conveying hot melt adhesive is provided on the box body, a cooling chamber for accommodating coolant is provided on the box body, a plurality of cooling pipes are provided in the cooling chamber, the cooling pipes are located above the coolant, a plurality of heat dissipation pipes are provided on the circumference of each cooling pipe, a guide structure is provided on the conveying structure with the same number of cooling pipes, each guide structure is arranged in parallel on the conveying structure and is connected to the corresponding cooling pipe at one end, and the hot melt adhesive enters the cooling pipe through the guide structure for heat dissipation. The hot melt adhesive of this application is cooled in the cooling pipe during the entire cooling process, which reduces the direct contact between the hot melt adhesive and water molecules, can reduce the amount of coolant attached to the surface of the hot melt adhesive, thereby shortening the drying time in the later stage and improving production efficiency. However, the cooling area of ​​the hot melt adhesive solid material in this cooling device is uneven, resulting in poor cooling effect, and it is inconvenient to repair when the device fails, affecting the cooling efficiency.

[0004] Therefore, in view of this, the shortcomings of the existing structure are studied and improved, and a hot melt adhesive cooling device is proposed. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1-Figure 2 As shown, a hot melt adhesive cooling device includes a fixed frame 1 and a conveyor belt 2. The conveyor belt 2 is arranged inside the conveyor fixed frame 1, and the top of the conveyor belt 2 is fixedly connected to a rotating mechanism 3. A protective cover 4 is arranged on the top of the fixed frame 1, and a disassembly mechanism 5 is fixedly connected to one side of the protective cover 4. The fixed frame 1 is located at the left and right ends of the conveyor belt 2 and supports the conveyor belt 2. The rotating mechanism 3 drives the hot melt adhesive fixed material formed by the hot melt adhesive raw material to rotate, thereby accelerating the cooling effect. The protective cover 4 is connected to the fixed frame 1 through the disassembly mechanism 5, which is convenient for maintenance when the device fails.

[0023] like Figure 3 As shown, the rotating mechanism 3 includes a fixed plate 301 fixedly connected to the top position of the conveyor belt 2, and an electric rotating rod 302 is fixedly connected to one side of the fixed plate 301, and one end of the electric rotating rod 302 is rotatably connected to a rolling shaft 303. There are multiple groups of rotating mechanisms 3 evenly arranged on the top of the conveyor belt 2. The gap between each group of rolling shafts 303 is small, and less hot melt adhesive fixing material falls from the gap to the top of the conveyor belt 2, which will not affect the cooling effect.

[0024] Furthermore, the disassembly mechanism 5 includes a clamping block 501 fixedly connected to one side of the protective cover 4, and a connecting rod 502 is provided inside the clamping block 501, and one end of the connecting rod 502 is rotatably connected to the fixed block 503, and a clamping groove is provided inside the clamping block 501. When the protective cover 4 is connected to the fixing frame 1, the connecting rod 502 is located inside the clamping groove. The protective cover 4 and the fixed block 503 can be disassembled by rotating the connecting rod 502.

[0025] Furthermore, a frequency converter 6 is fixedly connected to one side of the fixed frame 1, and a motor 7 is provided at the position of the frequency converter 6 on one side of the fixed frame 1. The frequency converter 6 can control the motor 7. The output end of the motor 7 is fixedly connected to the conveyor belt 2, thereby controlling the conveying speed of the conveyor belt 2 to achieve an efficient cooling speed.

[0026] Furthermore, the bottom of the fixed frame 1 is fixedly connected to the support frame 8, and the top of the protective cover 4 is fixedly connected to the first axial flow fan 9, the top of the protective cover 4 is provided with a second axial flow fan 10, and the top of the protective cover 4 is fixedly connected to the air inlet 11. The support frame 8 is located at the bottom of the device and supports the device. The first axial flow fan 9 and the second axial flow fan 10 run at the same time, which can speed up the cooling speed.

[0027] Furthermore, a delivery pipe 12 is provided at one end of the air inlet 11, and one end of the delivery pipe 12 is fixedly connected to a refrigerator 13. A shielding curtain 14 is provided at one end of the protective cover 4. The delivery pipe 12 connects the air inlet 11 with the refrigerator 13. The cold air discharged from the refrigerator 13 is delivered to the interior of the protective cover 4 through the delivery pipe 12. The shielding curtain 14 can prevent the cold air inside the protective cover 4 from being lost.

[0028] Working principle: When using the hot melt adhesive cooling device, first place the hot melt adhesive fixing material formed by the hot melt adhesive raw material on the rotating mechanism 3 on the top of the conveyor belt 2, start the first axial flow fan 9 and the second axial flow fan 10, and the cold air from the refrigerator 13 is transported to the inside of the protective cover 4 through the air inlet 11 at one end of the conveying pipe 12. Then, when the conveyor belt 2 is running, the electric rotating rod 302 on one side of the fixed plate 301 of the rotating mechanism 3 drives the rolling shaft 303 to rotate. If the conveying speed of the conveyor belt 2 is not appropriate, the motor 7 can be controlled by the frequency converter 6 to adjust the running speed of the conveyor belt 2. At this time, the hot melt adhesive fixing material starts to cool down as it moves. Finally, if a fault occurs inside the protective cover 4, rotate the connecting rod 502 inside the disassembly mechanism 5 to separate the connecting rod 502 from the clamping block 501, that is, the protective cover 4 and the fixing frame 1 can be removed for maintenance. This is the working principle of the hot melt adhesive cooling device.
