Description

Technical Field

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

[0002] In the production of hot melt adhesives, it is necessary to crush the hot melt adhesive lumps into powder for pneumatic conveying and subsequent processing. Therefore, powder impactors are often used for crushing. Powder impactors achieve ultrafine crushing by causing the granular materials to collide, bump, and rub against each other under the drive of high-speed airflow. However, hot melt adhesive powder is thermoplastic. During pneumatic conveying, it is prone to softening and sticking due to heat generated by friction with the pipe walls and impact components, or by fluctuations in ambient temperature, which can lead to pipe blockage. In addition, it is necessary to prevent external hot air from seeping into the equipment, as this would raise the temperature of the hot melt adhesive powder and increase the risk of sticking. Therefore, a cooling powder impactor is needed.

[0003] Chinese Utility Model Patent Publication No. CN205815905U discloses an online cooling and pulverizing device for hot melt adhesive. This device continuously cools the hot melt adhesive during the pulverizing process to prevent the powdered hot melt adhesive from clumping together. The conveying screw is hollow, resulting in low pressure on the hot melt adhesive during transport and minimizing internal energy generation. An air curtain nozzle is connected to the bottom of the pulverizing structure, using waste gas from the cooling process for reuse. The air curtain nozzle creates an air curtain effect during material feeding, preventing powder overflow. However, this online cooling and pulverizing device lacks a machine cover cooling structure, hindering uniform heat dissipation from the impactor body. This leads to an increase in the temperature of the hot melt adhesive powder during production, increasing the risk of adhesive separation. Furthermore, the lack of a shaft heat dissipation structure means that overheating of the shaft can affect the transmission between the motor and the impactor body. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a cooling and temperature-reducing powder impactor, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is: a cooling and heat-reducing powder impactor, including a fixed base, a motor fixedly installed on the fixed base and an impactor body connected to the motor, a transmission shaft connected to the impactor body fixedly installed on the output shaft of the fixed base, a cover cooling assembly fixedly installed on the outer edge of the impactor body, and a shaft cooling assembly fixedly installed on the end of the motor near the impactor body through a fixed flange.

[0006] The machine cover cooling assembly includes a cooling cover, and a cooling pipe one and a cooling pipe two are provided at the inner end of the cooling cover. Multiple cooling pipes one and two are provided, and a connecting pipe one and a connecting pipe two are provided at the connection points of multiple cooling pipes one and two.

[0007] The shaft cooling assembly includes a cooling box with a cooling groove at the inner end of the cooling box. The drive shaft passes through the cooling groove and extends to one end of the drive shaft near the impactor body.

[0008] Preferably, the inner surface of the cooling cover is provided with a through groove 1, which has the same structure as cooling pipe 1 and cooling pipe 2, and is interconnected with cooling pipe 1, cooling pipe 2, connecting pipe 1 and connecting pipe 2.

[0009] Through the above technical solution, by designing the first cooling pipe, the cooling medium can enter from the first cooling pipe, flow into the second cooling pipe through the first connecting pipe, continue to circulate through the second connecting pipe, and then be discharged from the second cooling pipe. This can remove the heat generated on the outer edge of the impactor body, effectively cool the impactor body, and prevent the impactor body from being affected by high temperature.

[0010] Preferably, there are two identical hood cooling assemblies, and both hood cooling assemblies have a semi-"C" shaped structure.

[0011] The above technical solution allows the two semi-C-shaped structures to tightly wrap around the outer edge of the impactor body, increasing the cooling area and improving the cooling effect. Furthermore, the two symmetrically distributed designs enable the impactor body to dissipate heat evenly, avoiding localized overheating.

[0012] Preferably, the inner surface of the cooling cover is provided with a groove, a connecting groove 2 and a water outlet groove that communicate with the cooling tank, and the end of the cooling cover away from the cooling tank is provided with a water inlet flange and a water outlet flange that communicate with the groove and the connecting groove 2.

[0013] The above technical solution provides inlet and outlet flanges for the cooling medium, which can be easily connected to external cooling pipes. With the groove, connecting groove 2 and outlet groove connected to the cooling tank, a shaft cooling channel can be realized, which can remove the heat generated by the operation of the drive shaft and avoid the transmission between the motor and the impact machine body due to overheating of the shaft.

[0014] Preferably, the cooling cover is provided with sealing gaskets made of rubber at both ends away from the center line, and the sealing gasket has a through groove of the same size as the drive shaft at the end near the center line.

[0015] The above technical solution utilizes a rubber gasket with good elasticity and sealing properties, which can tightly fit the cooling cover and drive shaft to prevent leakage of the cooling medium and ensure cooling circulation. The dimensions of the through groove three are adapted to the drive shaft, so as not to affect the normal rotation of the drive shaft and to play a sealing role.

[0016] Preferably, a connecting flange is provided on the outer surface of the impactor body, and two identical connecting flanges are provided, which are symmetrically distributed about the center line of the impactor body.

[0017] Through the above technical solution, the symmetrically distributed connecting flanges ensure that the impact machine body is subjected to uniform force during installation and operation, guarantee the stability of the connection, prevent the impact machine body from shifting or loosening due to uneven force, and facilitate the connection of the shaft cooling components.

[0018] Preferably, the impactor body has a feed inlet at one end away from the connecting flange, a feed hood at the other end away from the impactor body, and a discharge outlet and a discharge hood at the other end away from the feed hood.

[0019] Through the above technical solution, the design of the feed inlet and feed hood allows the material to enter the impactor body from the feed inlet and feed hood during processing, where it is then crushed. After processing, the material can be discharged through the discharge outlet and discharge hood, thus realizing the overall processing flow.

[0020] Compared with the prior art, this utility model provides a cooling and temperature-reducing powder impactor, which has the following beneficial effects:

[0021] 1. This cooling-type powder impactor, through the design of the machine cover cooling component, allows the cooling medium to enter from cooling pipe one, flow into cooling pipe two through connecting pipe one, and then continue to circulate through connecting pipe two. The two semi-"C" shaped structures can tightly wrap the outer edge of the impactor body, increasing the cooling area and improving the cooling effect. In addition, the two symmetrically distributed designs can make the impactor body dissipate heat evenly and avoid local overheating.

[0022] 2. This cooling-type powder impactor is interconnected with the cooling tank through grooves, connecting grooves, and water outlet grooves, which can realize the shaft cooling channel. It can remove the heat generated by the operation of the drive shaft, and avoid the transmission between the motor and the impactor body due to overheating of the shaft. In addition, the rubber sealing gasket has good elasticity and sealing performance, and can tightly fit the cooling cover and drive shaft to prevent the cooling medium from leaking, so as to ensure the cooling cycle.

[0031] 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.

[0032] Example 1: As Figure 1-7 As shown, the present invention provides a cooling and heat-reducing powder impactor, including a fixed base 1, a motor 2 fixedly installed on the fixed base 1 and an impactor body 4 connected to the motor 2. A transmission shaft 3 connected to the impactor body 4 is fixedly installed on the output shaft of the fixed base 1. A cover cooling assembly 10 is fixedly installed on the outer edge of the impactor body 4. A shaft cooling assembly 11 is fixedly installed on the end of the motor 2 near the impactor body 4 through a fixed flange.

[0033] The cooling assembly 10 includes a cooling cover 1001. Cooling pipe 1003 and cooling pipe 2 1006 are provided at the inner end of the cooling cover 1001. Multiple cooling pipes 1003 and cooling pipe 2 1006 are provided. Connecting pipe 1004 and connecting pipe 2 1005 are provided at the connection of multiple cooling pipes 1003 and cooling pipe 2 1006.

[0034] The shaft cooling assembly 11 includes a cooling box 1101, with a cooling groove 1105 opened at the inner end of the cooling box 1101. The drive shaft 3 passes through the cooling groove 1105 and extends to one end of it near the impactor body 4.

[0035] Specifically, the inner surface of the cooling cover 1001 is provided with a through groove 1002, which has the same structure as the cooling pipe 1003 and the cooling pipe 2 1006. It is interconnected with the cooling pipe 1003, the cooling pipe 2 1006, the connecting pipe 1 1004 and the connecting pipe 2 1005. The advantage is that, through the design of the cooling pipe 1003, a cooling medium such as water or coolant can be used to enter from the cooling pipe 1003, flow into the cooling pipe 2 1006 through the connecting pipe 1 1004, continue to circulate through the connecting pipe 2 1005, and then be discharged from the cooling pipe 2 1006. This can remove the heat generated on the outer edge of the impactor body 4, achieve effective cooling of the impactor body 4, and prevent the impactor body 4 from being affected by high temperature.

[0036] Specifically, there are two identical cooling assemblies 10 for the shroud. Both cooling assemblies 10 are semi-C-shaped. The advantage is that the two semi-C-shaped structures can tightly wrap around the outer edge of the impactor body 4, increasing the cooling area and improving the cooling effect. In addition, the two symmetrically distributed designs can make the impactor body 4 dissipate heat evenly and avoid local overheating.

[0037] Specifically, the inner surface of the cooling cover 1001 is provided with a groove 1102, a connecting groove 1104, and a water outlet groove 1106 that communicate with the cooling tank 1105. The end of the cooling cover 1001 away from the cooling tank 1105 is provided with a water inlet flange 1103 and a water outlet flange 1107 that communicate with the groove 1102 and the connecting groove 1104. The advantage is that the water inlet flange 1103 and the water outlet flange 1107 provide inlet and outlet for the cooling medium, which can be easily connected to external cooling pipes. With the groove 1102, the connecting groove 1104, and the water outlet groove 1106 communicating with the cooling tank 1105, a shaft cooling channel can be realized, which can remove the heat generated by the operation of the drive shaft 3 and avoid the transmission between the motor 2 and the impact machine body 4 due to overheating of the shaft.

[0038] Example 2: Figure 2-7 As shown, this is an improvement on the previous embodiment.

[0039] Specifically, the cooling cover 1001 is provided with rubber gaskets 1108 at both ends away from the center line. The end of the gasket 1108 near the center line has a through groove 1109 of the same size as the drive shaft 3. The advantage is that the rubber gasket 1108 has good elasticity and sealing performance, which can tightly fit the cooling cover 1001 and the drive shaft 3 to prevent the cooling medium from leaking and to ensure cooling circulation. The size of the through groove 1109 is adapted to the drive shaft 3, which does not affect the normal rotation of the drive shaft 3 and can also play a sealing role.

[0040] Specifically, a connecting flange 9 is provided on the outer surface of the impact machine body 4. There are two identical connecting flanges 9, which are symmetrically distributed about the center line of the impact machine body 4. The advantage is that the symmetrically distributed connecting flanges 9 ensure that the impact machine body 4 is subjected to uniform force during installation and operation, guarantee the stability of the connection, prevent the impact machine body 4 from shifting or loosening due to uneven force, and facilitate the connection of the shaft cooling assembly 11.

[0041] Specifically, the impactor body 4 is provided with a feed inlet 5 at one end away from the connecting flange 9, a feed hood 6 at the other end of the feed inlet 5 away from the impactor body 4, and a discharge outlet 7 and a discharge hood 8 at the other end of the impactor body 4 away from the feed hood 6. The advantage is that, through the design of the feed inlet 5 and the feed hood 6, the material can enter the impactor body 4 from the feed inlet 5 and the feed hood 6 during processing, and then be crushed. After processing, it can be discharged through the discharge outlet 7 and the discharge hood 8, thus realizing the overall processing flow.

[0042] Working Principle: During operation, the design of cooling pipe 1003 allows cooling media such as water or coolant to enter through it, flow into cooling pipe 1006 via connecting pipe 1004, continue circulating through connecting pipe 1005, and then exit through cooling pipe 1006. This effectively removes heat generated on the outer edge of the impactor body 4, preventing overheating from affecting its normal operation. The two semi-C-shaped structures tightly wrap around the outer edge of the impactor body 4, increasing the cooling area and improving the cooling effect. Their symmetrical distribution ensures even heat dissipation, preventing localized overheating. Inlet flange 1103 and outlet flange 1107 provide inlet and outlet for the cooling medium, facilitating connection to external cooling pipes. The groove 1102, connecting groove 1104, and outlet groove 1106 connect to the cooling groove 1105, creating a shaft cooling channel. The heat generated by the operation of the drive shaft 3 can be carried away, preventing the transmission between the motor 2 and the impactor body 4 from being affected by overheating of the shaft. The rubber sealing gasket 1108 has good elasticity and sealing performance, and can tightly fit the cooling cover 1001 and the drive shaft 3 to prevent the cooling medium from leaking and to ensure cooling circulation. The size of the through groove 1109 is adapted to the drive shaft 3, which does not affect the normal rotation of the drive shaft 3 and can also play a sealing role. The symmetrically distributed connecting flanges 9 make the impactor body 4 evenly stressed during installation and operation, ensuring the stability of the connection and preventing the impactor body 4 from shifting or loosening due to uneven stress. It can facilitate the connection of the shaft cooling assembly 11. Through the design of the feed port 5 and the feed cover 6, the material can enter the impactor body 4 from the feed port 5 and the feed cover 6 during processing, and then be crushed. After processing, it can be discharged through the discharge port 7 and the discharge cover 8, realizing the overall processing flow.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
