Description

Technical Field

[0001] This utility model relates to the field of cooling device technology, specifically a cooling device for producing adhesives. Background Technology

[0002] Adhesives are organic or inorganic, natural or synthetic substances that can join together two or more homogeneous or heterogeneous parts (or materials) and, after curing, possess sufficient strength. They are commonly referred to simply as glue. Adhesives can be natural polymers (starch, animal hide glue, bone glue, natural rubber, etc.), synthetic polymers (epoxy resins, phenolic resins, urea-formaldehyde resins, thermosetting resins such as polyurethane and thermoplastic resins such as polyvinyl acetal and chlorinated polyvinyl chloride, and synthetic rubbers such as chloroprene rubber and nitrile rubber), or inorganic compounds (silicates, phosphates, etc.). Depending on the application requirements, adhesives often incorporate curing agents, accelerators, reinforcing agents, release agents, fillers, etc. They can also be classified by application, such as room temperature adhesives, sealants, and structural adhesives. According to the application process, they can be classified as room temperature curing adhesives and pressure-sensitive adhesives. Adhesives can be used to join dissimilar materials and thin sheet materials, resulting in uniform stress distribution at the bond joint. Epoxy resin, neoprene rubber, and sealants are commonly used in container manufacturing and repair. After production, adhesives are stored in tanks. Existing storage tanks have cooling functions to lower the production temperature of the adhesives. However, in actual production, cooling the adhesives after they are fully injected into the storage tank results in low cooling efficiency and uneven cooling. Therefore, we propose a cooling device for adhesive production. Utility Model Content

The liquid injection assembly injects cooled water into the two spiral cooling pipes to cool the adhesive entering the guide pipe.

[0007] Furthermore, the cooling assembly includes a fixed frame, a cooling fan, and a thermoelectric cooler.

[0008] Furthermore, the flow guiding assembly includes a connecting ring, a fixing plate, and a spiral flow guiding rod. The upper end of the flow guiding tube is threaded with a connecting ring, and the connecting ring is fixed with evenly distributed fixing plates.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 This embodiment provides a technical solution: a cooling device for producing adhesives, including a guide pipe 1 and a liquid injection assembly 5;

[0021] Guide tube 1: Two spiral cooling tubes 2 with opposite spiral directions are fixed on the circumferential surface. The upper and lower ends of the two spiral cooling tubes 2 are connected by two connecting tubes 3. A guide assembly 4 is installed inside the guide tube 1. The guide assembly 4 includes a connecting ring 41, a fixing plate 42 and a spiral guide rod 43. The upper end of the guide tube 1 is threaded with a connecting ring 41. The connecting ring 41 is fixed with evenly distributed fixing plates 42. A spiral guide rod 43 is fixed between all the fixing plates 42. The spiral guide rod 43 is slidably connected inside the guide tube 1. By setting the spiral guide rod 43, the time that the adhesive stays inside the guide tube 1 is extended.

[0022] Liquid injection assembly 5 includes a water tank 51, a temperature sensor 52, a water pump 53, an outlet pipe 54, and a return pipe 55. The temperature sensor 52 is installed inside the water tank 51. The water pump 53 is installed below the temperature sensor 52. The outlet pipe 54 is fixed inside the outlet of the water pump 53 and is connected to the connecting pipe 3 below. The return pipe 55 is fixed inside the return port on the upper side of the water tank 51 and is connected to the connecting pipe 3 above. A cooling assembly 6 is installed on the right side of the water tank 51. The temperature sensor 52 is bidirectionally electrically connected to an external PLC controller. The cooling assembly 6 includes a fixing frame 61, a cooling fan 62, and a semiconductor cooling chip 63. A mounting slot is provided on the right side of the tank 51. A thermoelectric cooler 63 is installed inside the mounting slot. The heat dissipation end of the thermoelectric cooler 63 is located outside the mounting slot, and the cooling end of the thermoelectric cooler 63 is located inside the mounting slot. A fixing frame 61 is fixed on the right side of the water tank 51. Two corresponding cooling fans 62 are installed inside the fixing frame 61. The input ends of the cooling fans 62 and the thermoelectric cooler 63 are electrically connected to the output end of an external PLC controller. The water inside the water tank 51 is cooled by the cooling assembly 6. The cooled water is injected into the two spiral cooling pipes 2 by the liquid injection assembly 5 to cool the adhesive entering the guide pipe 1.

[0023] Among them: a support block 7 is fixed on the left side of the water tank 51, and a protective pipe 8 is fixed on the left side of the support block 7. The protective pipe 8 is fixed on the surface of the two spiral cooling pipes 2, and the two spiral cooling pipes 2 are protected by the protective pipe 8.

[0024] The water tank 51 has a water inlet hole on its upper side, and a sealing cap 9 is threaded inside the water inlet hole to seal the water tank 51.

[0025] Wherein: two corresponding connecting flange rings 10 are fixed at the upper and lower ends of the circumferential surface of the guide pipe 1. The end face of the connecting flange ring 10 is provided with evenly distributed connecting holes 11. By setting the two connecting flange rings 10, the guide pipe 1 is connected to the discharge pipe of the adhesive generating device and the inlet pipe of the adhesive storage tank respectively.

[0026] The working principle of the cooling device for producing adhesives provided by this utility model is as follows: The adhesive enters the guide pipe 1 from the upstream pipe and flows in a spiral shape under the guidance of the spiral guide rod 43. The spiral guide rod 43 extends the residence time of the adhesive in the guide pipe 1, increasing its contact time with the two spiral cooling pipes 2, thereby achieving sufficient heat exchange. The cooling water in the water tank 51 is pressurized by the water pump 53 and pumped into the lower connecting pipe 3 through the outlet pipe 54, where it is diverted to the two spiral cooling pipes 2 with opposite spiral directions. After absorbing heat from the adhesive, the cooling water flows back to the water tank 51 through the upper connecting pipe 3 and into the return pipe 55. Temperature sensor 52 monitors water temperature in real time. When the temperature exceeds the limit, the PLC controller activates semiconductor cooling chip 63 to cool the water. Simultaneously, cooling fan 62 forces air cooling to the heat dissipation end of semiconductor cooling chip 63 to maintain the low temperature of the cooling water. During the adhesive cooling process, protective tube 8 provides physical protection for spiral cooling tube 2 to prevent external collisions from damaging the pipes. Sealing cap 9 ensures the airtightness of water tank 51 through threaded sealing to prevent cooling water contamination. The flow guide assembly 4 is quickly disassembled and assembled through the threaded connection between connecting ring 41 and flow guide tube 1, facilitating cleaning or replacement of spiral flow guide rod 43 and adapting to the cooling requirements of adhesives with different viscosities.

[0027] It is worth noting that the external PLC controller disclosed in the above embodiments is specifically a Siemens S7-200. The temperature sensor 52, water pump 53, cooling fan 62 and thermoelectric cooler 63 can be freely configured according to the actual application scenario. The external PLC controller controls the operation of the water pump 53, cooling fan 62 and thermoelectric cooler 63 using methods commonly used in the prior art.
