The water outlet end 1231 of the circulating water pipe 123 is connected to the water tank 122 and is connected to the water outlet pipe rack 3 arranged in the cooling chamber 110 through the circulating pump 121. A plurality of nozzles 31 are arranged on the water outlet pipe rack 3 placed above the placement rack 2. The water inlet end 1232 of the circulating water pipe 123 is connected to the water tank 122 at one end and connected to the drain outlet 41 at the bottom of the water sump 4 provided below the placement rack 2 at the bottom of the cooling chamber 110.

[0026] Specifically in this embodiment, Figure 1The overall structure of the cooling and shaping device for hot melt adhesive processing shown in the figure can place the batch of hot melt adhesive that has been preliminarily formed by the mold on the placement rack 2 provided in the cooling chamber 110 when in use. The batch of hot melt adhesive placed on the placement rack 2 can be cooled by the circulating cooling component 1 provided on the frame 100. Specifically, the air cooling component 11 and the water cooling component 12 can be controlled separately by the control box 13 provided on the frame 100. When the air cooling component 11 is working, it can continuously blow cold air into the cooling chamber 110 along the ventilation duct 112 under the action of the fan 111 installed on the top of the cooling chamber 110. At the same time, the water cooling component 12 is working, and a certain amount of circulating water can be added and stored in the water storage tank 122. The circulating water in the water storage tank 122 can enter the circulating water pipe 123 under the action of the circulating pump 121 and move accordingly along the direction of the water outlet end 1231, and then enter the water outlet pipe rack 3 arranged inside the cooling chamber 110 and can be set at the corresponding position of the water outlet pipe rack 3. There are several nozzles 31, which continuously spray circulating water on the batch of hot melt adhesive on the placement rack 2. The circulating water sprayed by the nozzles 31 on the placement rack 2 can drip to the bottom of the cooling chamber 110 through the several water filter holes 222 opened thereon, and then enter the water collection tank 4 with the corresponding structure at the bottom of the cooling chamber 110 for storage. The circulating water stored in the water collection tank 4 to a certain amount can enter the corresponding connected circulating water pipe 123 through the drain port 41 opened at the bottom thereof, and flow back to the water storage tank 122 along its water outlet end 1231 to complete the entire circulation process.

[0027] from Figure 1 It can be seen that the placement rack 2 is arranged in a chain conveyor structure, including a conveying rack 21 and a conveying chain 22 formed by a plurality of conveying chains 22 plates rotatably arranged on the conveying rack 21, and a driving component 23 for driving the conveying chain 22 to rotate is provided on the conveying rack 21. The conveying rack 21 is placed between the feeding port 1101 and the discharging port 1102 on both sides of the cooling chamber 110. Baffles 221 are provided on the conveying chain 22 plates, and a plurality of water filter holes 222 are provided on the conveying chain 22 plates between adjacent baffles 221. Specifically, when in use, the driving component 23 on the conveying rack 21 can drive the conveying chain 22 to rotate, and batches of hot melt adhesive can be placed on the conveying chain 22 plates corresponding to the conveying chain 22. Figure 4The corresponding feed port 1101 at one end of the cooling chamber 110 shown cooperates with the hot melt adhesive mold that is rotated during the hot melt adhesive production process to carry out the feeding process of batch hot melt adhesive. At the same time, the hot melt adhesive can be isolated and placed by the baffle 221 provided on the conveyor chain 22 plate and enter the cooling chamber 110 along the direction of the discharge port 1102 on the other side as the conveyor chain 22 rotates. The circulating cooling component 1 in the cooling chamber 110 works to cool and shape the batch hot melt adhesive placed on the conveyor chain 22. The circulating water sprayed by the water-cooling component 12 through the several nozzles 31 on the water outlet pipe rack 3 can be filtered out through the several water filter holes 222 correspondingly opened on the several conveyor chain 22 plates, and enter the water collecting tank 4 at the bottom of the cooling chamber 110 for subsequent circulation process. The hot melt adhesive in the cooling chamber 110 that has been cooled and shaped by the circulating cooling component 1 can be rotated by the conveyor chain 22 on the conveyor rack 21. Figure 5 The discharge port 1102 corresponding to the other side of the cooling chamber 110 shown in the figure completes the discharge process of the hot melt adhesive. The placement rack 2 arranged in the chain conveyor structure can be used in conjunction with the production needs of the hot melt adhesive. On the premise of ensuring the stability of the hot melt adhesive during cooling and molding, the cooling efficiency of the hot melt adhesive can be further improved. In addition, the setting of the baffle 221 on the conveying chain 22 can also improve the molding effect of the hot melt adhesive, effectively avoiding the occurrence of situations such as adhesion due to its unnecessary displacement process during the conveying process that affects the molding stability, thereby expanding the scope of application of this cooling and molding device and improving its applicability.

[0028] A collecting box 5 is also provided at a corresponding position below the conveying frame 21 on one side of the discharge port 1102. Figure 5 As shown in , the addition of the collection box 5 at the discharge port 1102 can facilitate the unified collection of the batch of hot melt adhesives after cooling and forming on the conveyor chain 22, facilitate subsequent packaging and other operations, and improve ease of use and work efficiency.

[0029] The side walls of the cooling chamber 110 are provided with observation windows 1103 at corresponding positions above the feed port 1101 and the discharge port 1102. Figure 4 and Figure 5 It can be seen that the setting of the corresponding observation windows 1103 on both sides of the cooling chamber 110 can facilitate the observation and timely adjustment of the real-time cooling and molding conditions of the circulating cooling component 1 and its corresponding hot melt adhesive in the cooling chamber 110, thereby improving the use effect and working stability of this cooling and molding device.

[0030] The cooling chamber 110 is hinged with a door assembly 1104, which is provided with a mounting groove of an appropriate size, and a glass is mounted on the mounting groove. Figure 1As can be seen, the structure of the cooling chamber 110 corresponds to the door group 1104, which can ensure a certain airtightness in the cooling chamber 110, facilitate operation and processing of the interior of the cooling chamber 110, and further expand the visual range of the interior of the cooling chamber 110 by installing glass on the corresponding mounting groove of the door group 1104, so as to facilitate timely processing of abnormal conditions in the cooling chamber 110.

[0031] The ventilation pipe 112 placed on the top of the cooling chamber 110 is provided with a plurality of fins on the corresponding ventilation opening, as shown in Figure 3 As shown in the figure, the plurality of fins on the corresponding ventilation opening of the ventilation pipe 112 can further improve the uniformity of the circulating air blown out by the fan 111 in the ventilation pipe 112 in the cooling chamber 110, and can effectively reduce the unnecessary influence of impurities entering the ventilation pipe 112 on the working of the fan 111, thereby improving the working stability of the air cooling assembly 11.

[0032] The water collecting tank 4 is also detachably provided with a filter plate 6, as shown in Figure 6 As shown in the figure, the filter plate 6 is adapted and clamped by the clamping groove 42 provided at the corresponding position in the water collecting tank 4, which facilitates the installation, disassembly, replacement and cleaning of the filter plate 6. In addition, the addition of the filter plate 6 in the water collecting tank 4 can filter the circulating water in the water collecting tank 4, improve the cleanliness of the circulating water, effectively reduce the probability of the phenomenon that impurities enter the bottom of the water collecting tank 4 and block the drain port 41, and improve the circulation stability and efficiency of the circulating water during the working process of the water cooling assembly 12.

[0033] The bottom of the feeding port 1101 and the discharging port 1102 is provided with a guide plate 1105 below the corresponding position of the conveying frame 21, as shown in Figure 6 As shown in the figure, the structure and installation position of the guide plate 1105, the guide plate 1105 can guide the circulating water dropped near the feeding port 1101 and the discharging port 1102 on both sides of the bottom of the conveying frame 21 in the cooling chamber 110, reduce the probability of the phenomenon that the circulating water leaks, and improve the circulation effect and utilization rate of the circulating water in the cooling chamber 110.

[0034] The air cooling assembly 11 further comprises a filter assembly 7 connected between the water outlet end 1231 of the circulating water pipe 123 and the water storage tank 122, and the filter assembly 7 comprises a filter water tank 71 connected with the second drain port 43 provided at the bottom of the water collecting tank 4 and a filter 72 connected with the filter water tank 71 and the water storage tank 122, which can be seen in Figure 6 and Figure 1As shown in the figure, a certain amount of circulating water stored in the water collection tank 4 can enter the filter tank 71 connected to it through the second drain outlet 43 opened at the corresponding position of the bottom thereof. The circulating water in the filter tank 71 can be filtered under the action of the filter 72 and then enter the water storage tank 122. The addition of the filter assembly 7 can play a certain filtering and cleaning role for the circulating water in the water collection tank 4 before entering the water storage tank 122 by controlling the drain outlet 41 and the second drain outlet 43 at the bottom of the water collection tank 4, thereby improving the cleanliness of the circulating water, reducing the generation of scale in the water storage tank 122, and improving the use effect and use time of the circulating water.

[0035] The water filter tank 71 is also connected to the water inlet 1232 of the circulation pump 121 through the filter 72. Figure 1 It can be seen that the circulating water in the filter tank 71 can enter the circulating pump 121 along the water inlet end 1232 of the circulating pump 121 after being filtered by the filter 72. Therefore, according to the use requirements, when the filter component 7 is working, the filter 72 can simultaneously play a certain cleaning role on the inside of the circulating pump 121, thereby further improving the working efficiency and service life of the circulating pump 121.
