[0004] The above technology realizes uniform cooling of the material by long-distance reciprocating movement of the nozzle, which takes a long time to fully cool the material and has low cooling efficiency. Therefore, the utility model discloses a cooling device for an aluminum extruder to solve the above problem. Utility Model Content

[0005] The purpose of the utility model is to provide a cooling device for an aluminum extruder to solve the problem that the traditional cooling equipment proposed in the above background technology realizes uniform cooling of the material through long-distance reciprocating movement of the nozzle, takes a long time to fully cool the material, and has low cooling efficiency.

[0006] To achieve the above objectives, the present invention solves the above technical problems as follows:

[0007] A cooling device for an aluminum extruder includes a recovery cooling bin, both sides of which are provided with anti-splash ribs, multiple spray frames and multiple drive rollers are connected between the two anti-splash ribs, spray heads are fixedly embedded on the upper and lower adjacent side walls of the spray frames, multiple drive rollers are transmission-connected to the drive assembly, and multiple spray frames are connected to the pressurized pipe.

[0008] As a further solution of the present invention, a plurality of the spray frames are arranged at equal intervals, and a driving roller is provided between adjacent spray frames.

[0009] As a further solution of the present invention, a transmission shaft is fixedly sleeved on the middle part of each driving roller, and the transmission shaft is rotatably connected between the two anti-splash ribs.

A drive shaft is rotatably connected between the two side end walls of the mechanical transmission box. A plurality of driving bevel gears are fixed to the outside of the drive shaft. A driven bevel gear is fixed to one end of the transmission shaft extending into the mechanical transmission box.

[0011] As a further solution of the present invention, the spray frame is fixedly embedded between two anti-splash ribs, and the spray frame is a rectangular frame made of a hollow tube.

[0012] As a further solution of the present invention, a drainage pipe is fixedly embedded on one side of the bottom of the recovery cooling bin, and two supporting steels are fixedly connected to both ends of the bottom side of the recovery cooling bin.

[0013] As a further solution of the present invention, the outer sides of the driving rollers are provided with anti-slip patterns.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The constant temperature and pressure batching tank pumps cold water into the pressurized pipe. The cold water enters the spray head through each spray frame and is sprayed out. The cold water sprays on the high-temperature aluminum profile and quickly evaporates and absorbs heat, thereby reducing the temperature of the aluminum profile;

[0016] 2. This constant temperature and pressure batching tank injects new liquid raw materials into the upward pipe, and the drive motor drives the drive shaft to rotate, which drives multiple active bevel gears to rotate. The active bevel gears mesh with the adjacent driven bevel gears, and the driven bevel gears drive the transmission shaft to rotate, so that multiple drive rollers rotate continuously to transmit aluminum profiles, realizing one belt with multiple transmissions. The anti-slip texture on the surface of the drive rollers increases friction, which ensures that the aluminum profiles can be stably transmitted during the cooling process.

[0017] 3. The constant temperature and pressure batching tank has spray heads arranged on the upper and lower sides of the aluminum profile, which can simultaneously cool down the surrounding areas of the aluminum profile. After the aluminum profile has completely entered the cooling area, it can be driven by the drive roller to move repeatedly to continuously switch the position of the spray area, which can ensure that all parts of the aluminum profile are fully cooled.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] See also Figure 1-6 The utility model provides a cooling device for an aluminum extruder, comprising a recovery cooling bin 1, a drain pipe 12 being fixedly embedded on one side of the bottom of the recovery cooling bin 1, and two support steels 13 being fixedly connected to both ends of the bottom side of the recovery cooling bin 1;

[0028] Specifically, during the cooling process of the aluminum profile, the cold water sprayed from the sprinkler head 4 will come into contact with the high-temperature aluminum profile and evaporate rapidly. At the same time, some water will flow directly to the bottom of the recovery cooling bin 1. The presence of the drain pipe 12 ensures that the water can be discharged in time to avoid accumulation in the recovery cooling bin 1. The function of the support steel 13 is to provide additional stability and strength for the recovery cooling bin 1, which helps to evenly disperse the force on the bottom surface of the recovery cooling bin 1 and extend the service life of the recovery cooling bin 1.

[0029] Furthermore, both sides of the recovery cooling bin 1 are provided with splash-proof ribs 11;

[0030] Specifically, the anti-splash rib 11 defines the boundary of the recovery cooling bin 1, ensuring that the aluminum profile remains within the predetermined cooling area during the cooling process, preventing the aluminum profile from deviating from the cooling area, and during the cooling process, the water sprayed from the sprinkler head 4 may splash, and the anti-splash rib 11 can prevent the water from splashing outside the cooling area, keeping the working environment clean.

[0031] Furthermore, a plurality of spray frames 2 and a plurality of driving rollers 3 are connected between the two anti-splash ribs 11, and the outer sides of the driving rollers 3 are provided with anti-slip patterns 32;

[0032] Specifically, the anti-slip pattern 32 can increase the friction between the driving roller 3 and the aluminum profile to ensure that the aluminum profile can be stably transmitted by the driving roller 3 during the cooling process of the aluminum profile, and prevent the aluminum profile from sliding or shifting due to insufficient friction during the cooling process. It is worth noting that the anti-slip pattern 32 can be a grid-shaped, wavy or strip-shaped structure.

[0033] Furthermore, the upper and lower adjacent side walls of the spray frame 2 are fixedly embedded with spray heads 4;

[0034] Specifically, the spray heads 4 are arranged on the upper and lower adjacent side walls of the spray frame 2, which can ensure that the upper and lower surfaces of the aluminum profile are evenly cooled when passing through the cooling area, thereby achieving a comprehensive cooling effect. By arranging the spray heads 4 on the upper and lower side walls, the cooling area can be increased, the cooling efficiency can be improved, and the cooling time of the aluminum profile can be shortened. The uniform distribution of the spray heads 4 helps to evenly reduce the temperature of each part of the aluminum profile during the cooling process, avoiding quality problems caused by local overheating or overcooling.

[0035] Furthermore, the plurality of driving rollers 3 are all in transmission connection with the driving assembly 5, and a transmission shaft 31 is fixedly sleeved on the middle portion of each driving roller 3, and the transmission shaft 31 is rotatably connected between the two anti-splash ribs 11;

[0036] Specifically, the driving roller 3 is connected to the driving assembly 5 via the transmission shaft 31 , which ensures effective transmission of power. The rotation of the transmission shaft 31 can drive the driving roller 3 to rotate synchronously.

[0037] Furthermore, the drive assembly 5 includes a mechanical transmission box 51 fixed to one side of one of the splash-proof ribs 11 and a drive motor 52 fixed to an end face of one side of the mechanical transmission box 51. A drive shaft 53 is rotatably connected between the end walls of the mechanical transmission box 51. A plurality of driving bevel gears 54 are fixed to the outside of the drive shaft 53. A driven bevel gear 55 is fixed to one end of the transmission shaft 31 extending into the mechanical transmission box 51. Adjacent driving bevel gears 54 and driven bevel gears 55 are meshed and connected, and the output end of the drive motor 52 is fixedly connected to the drive shaft 53.

[0038] Specifically, the driving motor 52 drives the driving shaft 53 to rotate, the driving shaft 53 drives multiple active bevel gears 54 to rotate, the active bevel gears 54 engage and transmit adjacent driven bevel gears 55, and the driven bevel gears 55 drive the transmission shaft 31 to rotate, so that multiple driving rollers 3 rotate synchronously to transmit aluminum profiles. After the aluminum profiles completely enter the cooling area, the output shaft of the driving motor 52 is controlled to rotate forward and reverse intermittently, which can drive the aluminum profiles to move repeatedly in the cooling area, ensuring that all parts of the aluminum profiles are fully cooled and have a high degree of automation.

[0039] Furthermore, the plurality of spray frames 2 are all connected to the pressurized pipe 6;

[0040] Specifically, by connecting the pressurized pipe 6 to the water pump, it can be ensured that the cooling water has sufficient pressure before entering the spray frame 2, so that the spray head 4 can spray water at a higher pressure, thereby improving the cooling efficiency. The pressurized pipe 6 serves as the main water supply channel, which facilitates centralized control of the flow and pressure of the cooling water, and the cooling intensity can be adjusted as needed. The pressurized pipe 6 evenly transports the cooling water to each spray frame 2, ensuring that each spray head 4 can obtain sufficient water pressure and water volume to achieve uniform cooling.

[0041] Furthermore, the plurality of spray frames 2 are arranged at equal distances, and driving rollers 3 are provided between adjacent spray frames 2;

[0042] Specifically, the equidistantly arranged spray frames 2 can ensure that the aluminum profile can evenly receive the cold water sprayed from each spray head 4 when passing through the cooling area, thereby achieving uniform cooling of the aluminum profile. Since the spray frames 2 are equidistantly distributed, each part of the aluminum profile can be fully cooled during the cooling process, which helps to improve the cooling efficiency and shorten the cooling time. The driving rollers 3 arranged between adjacent spray frames 2 can stably transmit the aluminum profile. The equidistantly arranged spray frames 2 and driving rollers 3 can increase the cooling speed and stability of the aluminum profile, thereby improving the efficiency and production capacity of the entire production line.

[0043] Furthermore, the spray frame 2 is fixedly embedded between the two anti-splash ribs 11, and the spray frame 2 is a rectangular frame made of a hollow tube;

[0044] Specifically, the hollow tube structure of the spray frame 2 allows cold water to flow therein and be evenly sprayed out through the spray head 4. This design helps to improve the cooling efficiency, so that the aluminum profile can be cooled quickly and evenly. The spray frame 2 is fixed between the two anti-splash ribs 11, which can ensure that the spray head 4 is evenly distributed in the cooling area of ​​the aluminum profile, thereby achieving comprehensive cooling of the aluminum profile.

[0045] Working principle: When in use, the aluminum profile processed by the extruder is transmitted to the upper side of the recovery cooling bin 1, and the driving motor 52 drives the driving shaft 53 to rotate, and the driving shaft 53 drives multiple active bevel gears 54 to rotate, and the active bevel gear 54 engages and transmits the adjacent driven bevel gear 55, and the driven bevel gear 55 drives the transmission shaft 31 to rotate, so that multiple driving rollers 3 rotate synchronously to transmit the aluminum profile. At the same time, cold water is pumped into the pressurized pipe 6, and the cold water enters the spray head 4 through each spray frame 2 and is sprayed out. The cold water sprayed on the high-temperature aluminum profile can quickly evaporate and absorb heat, thereby reducing the temperature of the aluminum profile. After the aluminum profile completely enters the cooling area, the output shaft of the driving motor 52 is controlled to rotate intermittently forward and reverse, which can drive the aluminum profile to move repeatedly in the cooling area, which can ensure that all parts of the aluminum profile are fully cooled, and the degree of automation is high.
