Description

Technical Field

[0001] This utility model relates to the field of hot melt adhesive granulation technology, specifically a hot melt adhesive cooling granulation device. Background Technology

[0002] Hot melt adhesive granulation technology requires adding hot melt adhesive raw materials into an extruder to heat and extrude the raw materials. The extruded hot melt adhesive strip is then passed into a cooling tank, where water is used to cool the hot melt adhesive strip, allowing it to fully solidify. The solidified hot melt adhesive strip is then fed into a granulator, where the hydraulic system controls the cutters to cut the solidified hot melt adhesive strip into uniform granules. After granulation, the hot melt adhesive granules are screened through a sieve to remove oversized or undersized particles and impurities, thus obtaining qualified adhesive granules.

[0003] Currently, in existing technologies, the cooling and curing process in hot melt adhesive granulation uses either cooling water or air cooling. Air cooling requires a long production line, resulting in a large footprint for the equipment. In contrast, with cooling water cooling, the heat from the hot melt adhesive strip is absorbed by the cooling water, causing the cooling water to heat up and thus reducing the cooling rate of the hot melt adhesive strip. Furthermore, workers are required to clean the water off the hot melt adhesive strip. Therefore, a hot melt adhesive cooling granulation device is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a hot melt adhesive cooling granulation device with the advantages of efficient circulating cooling. It solves the problem that the cooling and curing process in hot melt adhesive granulation uses either cooling water or air cooling. Air cooling requires a long production line, resulting in a large footprint for the equipment. In contrast, water cooling absorbs the heat from the hot melt adhesive strip, causing the water to heat up and reducing the cooling speed of the hot melt adhesive strip. Furthermore, it requires workers to clean the water off the hot melt adhesive strip.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hot melt adhesive cooling and granulation device, including a processing table, a granulator and an extruder on the processing table, and a cooling structure and a cleaning structure on the processing table;

[0006] The cooling structure includes a dual-chamber cooling tank fixedly installed on the top of the processing table and located between the extruder and the granulator. A chiller for cooling water is fixedly installed on the top of the processing table. A spray component for spraying and cooling the hot melt adhesive strip is installed on the front of the chiller. A water level sensor is fixedly installed in the left chamber of the dual-chamber cooling tank. A water circulation component for recycling cooling water is installed on the dual-chamber cooling tank and the chiller. A drying component for further cooling and drying is installed in the right chamber of the dual-chamber cooling tank.

[0007] Furthermore, an installation frame is fixedly installed on the right side of the dual-cavity cooling tank, and two cleaning frames are fixedly installed inside the installation frame. Sponge rollers for cleaning water stains on the surface of hot melt adhesive strips are rotatably installed between the front and rear side walls of the inner cavities of the two cleaning frames.

[0008] Furthermore, the granulator is fixedly installed on the top of the processing table, and a feed hopper is fixedly installed on the granulator. The extruder is also fixedly installed on the top of the processing table.

[0009] Furthermore, the spraying component includes a three-pronged water pipe and two nozzles. The two ends of the three-pronged water pipe pass through and extend into the left chamber of the dual-chamber cooling tank. The two ends of the three-pronged water pipe are respectively fixedly connected to the two nozzles. A control valve is fixedly installed on the three-pronged water pipe and the three-pronged water pipe is connected to the chiller.

[0010] Furthermore, the water circulation component includes a connecting water pipe and a water pump. The water pump is fixedly installed in the chiller and is fixedly connected to the connecting water pipe. One end of the connecting water pipe passes through and extends into the left chamber of the dual-chamber cooling tank. The water pump is electrically connected to a water level sensor.

[0011] Furthermore, the air-drying component includes two fan frames, which are respectively fixedly installed on the front and rear side walls of the inner cavity of the right chamber of the dual-cavity cooling tank, and two high-speed fans are fixedly installed inside each of the two fan frames.

[0012] Furthermore, the mounting frame includes a connecting plate and a rectangular frame, which are fixedly connected. The connecting plate is fixedly connected to the right side of the dual-cavity cooling tank. The two cleaning frames are located on the inner top wall and inner bottom wall of the rectangular frame, respectively. A mounting bolt with one end penetrating the rectangular frame and extending into the cleaning frame is installed on the rectangular frame. The mounting bolt is threadedly connected to the cleaning frame.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] This hot melt adhesive cooling and granulation device, equipped with a cooling structure and a cleaning structure, utilizes a spray component to spray cooling water from a chiller onto the hot melt adhesive strip. The cooling water absorbs the heat from the hot melt adhesive strip and falls into a dual-chamber cooling tank for final collection. Then, a high-speed fan in the drying component dries the water droplets on the hot melt adhesive strip, causing the cooling water to vaporize and carry away any residual heat, allowing the hot melt adhesive strip to completely solidify. Finally, two sponge rollers wrap the hot melt adhesive strip to remove water stains. Furthermore, the used cooling water is pumped back to the chiller by a water circulation component for further cooling, thus ensuring the temperature of the cooling water sprayed onto the hot melt adhesive strip and enhancing the practicality of the hot melt adhesive cooling and granulation device.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 Figures 1 to 3 The hot melt adhesive cooling and granulation device in this embodiment includes a processing table 1, a granulator 2 and an extruder 3 on the processing table 1, a cooling structure and a cleaning structure on the processing table 1, the granulator 2 being fixedly installed on the top of the processing table 1, a feed hopper being fixedly installed on the granulator 2, and the extruder 3 being fixedly installed on the top of the processing table 1.

[0021] In this embodiment, the cooling structure includes a dual-chamber cooling tank 41 fixedly installed on the top of the processing table 1 and located between the extruder 3 and the granulator 2. A chiller 42 for cooling water is fixedly installed on the top of the processing table 1. A spray component 43 for spraying and cooling hot melt adhesive strips is installed on the front of the chiller 42. The spray component 43 includes a three-pronged water pipe and two nozzles. The two ends of the three-pronged water pipe pass through and extend into the left chamber of the dual-chamber cooling tank 41. The two ends of the three-pronged water pipe are fixedly connected to the two nozzles respectively. A control valve is fixedly installed on the three-pronged water pipe and the three-pronged water pipe is connected to the chiller 42 to facilitate control of the cooling water passage in the three-pronged water pipe and the cooling water flow. The water is sprayed onto the hot melt adhesive strip. A water level sensor 44 is fixedly installed in the left chamber of the dual-chamber cooling tank 41. A water circulation component 45 for recovering cooling water is installed on the dual-chamber cooling tank 41 and the chiller 42. A drying component 46 for further cooling and drying is installed in the right chamber of the dual-chamber cooling tank 41. The drying component 46 includes two fan frames. The two fan frames are fixedly installed on the front and rear side walls of the inner cavity of the right chamber of the dual-chamber cooling tank 41, respectively. Two high-speed fans are fixedly installed inside the two fan frames, so that the water droplets on the hot melt adhesive strip can be dried by the four high-speed fans, and the residual heat in the hot melt adhesive strip can be removed by the vaporization of the cooling water.

[0022] The water circulation component 45 includes a connecting water pipe and a water pump. The water pump is fixedly installed in the chiller 42 and is fixedly connected to the connecting water pipe. One end of the connecting water pipe passes through and extends into the left chamber of the dual-chamber cooling tank 41. The water pump is electrically connected to the water level sensor 44 so that when the water level sensor 44 senses that the water level in the left chamber of the dual-chamber cooling tank 41 has reached a preset value, it starts the water pump in the water circulation component 45 and pumps the cooling water back into the chiller 42 for refrigeration.

[0023] Using the above technical solution, the control valve in the spray component 43 is opened, thereby spraying cooling water out through the three-way pipe and nozzle. The sprayed cooling water sprays the hot melt adhesive strip, thereby absorbing the heat on the hot melt adhesive strip to achieve cooling and curing. Then, the high-speed fan in the air drying component 46 blows the water droplets on the hot melt adhesive strip to dry it, so that the cooling water vaporizes and carries away the residual heat in the hot melt adhesive strip, allowing the hot melt adhesive strip to be completely cured. When the water level sensor 44 senses that the water level in the left chamber of the dual-chamber cooling tank 41 has reached the preset value, the water pump in the water circulation component 45 is started and the cooling water is pumped back to the chiller 42 for cooling.

[0024] In this embodiment, a mounting frame 47 is fixedly installed on the right side of the dual-cavity cooling tank 41. Two cleaning frames 48 are fixedly installed inside the mounting frame 47. The mounting frame 47 includes a connecting plate and a rectangular frame. The connecting plate and the rectangular frame are fixedly connected. The connecting plate is fixedly connected to the right side of the dual-cavity cooling tank 41. The two cleaning frames 48 are located on the inner top wall and inner bottom wall of the rectangular frame, respectively. A mounting bolt is installed on the rectangular frame, with one end penetrating through the rectangular frame and extending into the interior of the cleaning frame 48. The mounting bolt is threadedly connected to the cleaning frame 48, which facilitates the disassembly and assembly of the two sponge rollers 49. Sponge rollers 49 for cleaning water stains on the surface of hot melt adhesive strips are rotatably installed between the front and rear side walls of the inner cavity of the two cleaning frames 48.

[0025] Using the above technical solution, the cured hot melt adhesive strip passes between two sponge rollers 49, so that the two sponge rollers 49 wrap around the outer surface of the hot melt adhesive strip, thereby cleaning the water stains on the hot melt adhesive strip. Finally, the hot melt adhesive strip is sent to the granulator 2 for cutting and granulation.

[0026] The working principle of the above embodiments is as follows:

[0027] In use, the hot melt adhesive cooling and granulation device opens the control valve in the spray component 43, thereby spraying cooling water through the three-way pipe and nozzle. The sprayed cooling water sprays the hot melt adhesive strip, thereby absorbing the heat on the hot melt adhesive strip to achieve cooling and curing. Then, the high-speed fan in the drying component 46 blows the water droplets on the hot melt adhesive strip, causing the cooling water to vaporize and carry away the residual heat in the hot melt adhesive strip, so that the hot melt adhesive strip is completely cured. Subsequently, the cured hot melt adhesive strip passes between two sponge rollers 49, so that the two sponge rollers 49 wrap around the outer surface of the hot melt adhesive strip, thereby cleaning the water stains on the hot melt adhesive strip. Finally, the hot melt adhesive strip is sent to the granulator 2 for cutting and granulation. When the water level sensor 44 senses that the water level in the left chamber of the dual-chamber cooling tank 41 has reached the preset value, the water pump in the water circulation component 45 is started and the cooling water is pumped back to the chiller 42 for cooling.
