[0029] The “first” and “second” mentioned in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0030] like Figure 1-Figure 5As shown, an online standing wave quenching device in one embodiment of the present invention comprises a quenching table 1 and a cooling mechanism; a conveying structure 2 is mounted on the quenching table 1, baffles 3 which can be lifted and lowered relative to the conveying structure 2 are arranged on both sides of the conveying structure 2, and baffle assemblies 4 are respectively arranged on the feeding end and the discharging end of the conveying structure 2 facing each other, and a standing wave space is formed between the two baffle assemblies 4; the cooling mechanism is installed in the quenching table 1, and the cooling mechanism comprises an air cooling structure 5 and a water cooling structure 6, a plurality of air outlet pipe grooves 51 are arranged on the air cooling structure 5, and a plurality of water spray conduits 61 are arranged on the water cooling structure 6, and the air outlets of the air outlet pipe grooves 51 and the water spray outlets of the water spray conduits 61 are both facing the standing wave space.

[0031] The above-mentioned online standing wave quenching device, by providing a conveying structure 2, realizes the transportation and transfer of the aluminum profile after it is discharged from the extruder, facilitates the advancement of subsequent processes, and improves processing efficiency; by providing a material blocking component 4, a standing wave space is formed between the material blocking component 4 and the conveying structure 2, providing a closed space position for water-cooled standing wave quenching of the aluminum profile; by providing a baffle 3, when the aluminum profile enters the standing wave space and starts to be quenched, the operator can raise the height of the baffle 3 so that the baffle 3 can block the splashing of water in the standing wave space to avoid affecting the processing environment, while enabling the standing wave water flow to spray back and forth on the surface of the aluminum profile to ensure uniform cooling of the aluminum profile; by providing an air outlet pipe groove 51 and a water spray duct 61, the aluminum profile is cooled by air and water at the same time, thereby improving the cooling efficiency of the aluminum profile.

[0032] like Figure 1-Figure 5 As shown, in one embodiment, the quenching station 1 includes an inner frame 11, two sliding components 12 and an outer frame 13 for supporting the inner frame 11, the conveying structure 2 is mounted on the top of the inner frame 11, the air cooling structure 5 and the water cooling structure 6 are installed inside the inner frame 11, the two sliding components 12 are respectively installed on the outer side walls on both sides of the inner frame 11, and the baffle 3 is located between the inner frame 11 and the outer frame 13 and is slidably connected with the sliding components 12. In this way, by providing the outer frame 13, it is beneficial to protect the internal structure of the quenching station 1 and reduce the maintenance cost, and a gap is formed between the outer frame 13 and the inner frame 11, which is convenient for the lifting and lowering movement of the baffle 3; by providing the sliding component 12, the sliding component 12 controls the lifting and lowering movement of the baffle 3. When the quenching operation is not performed, the baffle 3 is hidden, which is helpful for real-time detection of the aluminum profile on the conveying structure 2 and improves the yield rate of the aluminum profile. When the quenching operation is required, the height of the baffle 3 is raised, which is helpful for sealing the standing wave space and preventing water splashing.

[0033] like Figure 1-Figure 5As shown, in one embodiment, a box 111 is provided in the inner frame 11, and a mounting plate is provided on the top cover of the box 111; the conveying structure 2 includes a limiting assembly 21, a plurality of conveying rollers 22, and a fixing seat 23 mounted on the side wall of the box 111, and a plurality of conveying rollers 22 are connected to the fixing seat 23 at intervals, and the limiting assembly 21 includes two limiting rods 211 symmetrically arranged on both sides of the fixing seat 23, and a baffle 212 is detachably fixed on the limiting rod 211, and the baffles 212 on both sides cooperate with the aluminum profile on the limiting conveying roller 22. In this way, by providing a plurality of conveying rollers 22 for transporting aluminum profiles, the rotation of the conveying rollers 22 is used to promote the movement of the aluminum profiles, thereby realizing automated transportation; by providing the baffles 212, when the aluminum profiles are transported on the conveying rollers 22, the baffles 212 on both sides can abut and limit the aluminum profiles, thereby preventing the aluminum profiles from being offset or even falling off, and improving the stability of the aluminum profiles during transportation.

[0034] like Figure 1-Figure 5 As shown, in one embodiment, the sliding assembly 12 includes a driving cylinder 121, a sliding member 122, and a guide rail 123 fixed on the outer wall of the inner frame 11, one end of the sliding member 122 is fixedly connected to the baffle 3, and the other end of the sliding member 122 is slidably connected to the guide rail 123, and the driving cylinder 121 is installed on the outer frame 13 and is used to control the lifting and lowering movement of the baffle 3. By providing the driving cylinder 121, the driving cylinder 121 controls the baffle 3 to slide along the setting direction of the guide rail 123 using the sliding member 122, so that the baffle 3 can reciprocate and lift, and then adjust the setting height of the baffle 3, which is conducive to achieving the sealing of the standing wave space and preventing the splashing of water flow in the standing wave space.

[0035] Specifically, the guide rail 123 is arranged in a vertical direction.

[0036] like Figure 1-Figure 5 As shown, in one embodiment, the air cooling structure 5 includes an air inlet duct 52 and an air blast assembly 53 fixed in the air inlet duct 52. The air inlet duct 52 is connected to the bottom of the box 111. A cavity is formed in the box 111. The air blasting port of the air blast assembly 53 faces the cavity. Multiple air outlet duct grooves 51 are all arranged on the mounting plate and connected to the cavity. In this way, the air blast assembly 53 can generate a higher wind pressure and air volume, and guide the cold air into the air inlet duct 52, and then finally spray out from the air outlet duct groove 51 after passing through the cavity, which is conducive to air cooling of the aluminum profiles on the conveying structure 2.

[0037] like Figure 7 and Figure 8As shown, in one embodiment, the blowing assembly 53 includes a cold fan 531, a driving motor 532, a connecting tube body 533 and a positioning seat 534 fixedly connected to the inner wall of the air inlet duct 52, the driving motor 532 is detachably mounted on the positioning seat 534, the output end of the driving motor 532 is transmission-connected to one end of the cold fan 531, the other end of the cold fan 531 is provided with a blade cover 535, one end face of the connecting tube body 533 is connected to the top of the blade cover 535, the other end face of the connecting tube body 533 is provided with an air outlet window 536, and the air outlet is arranged on the air outlet window 536. In this way, by providing a driving motor 532, the driving motor 532 controls the cold fan 531 to generate a higher wind pressure and air volume, so that the cold fan 531 can transfer the cold air to the connecting pipe body 533 and finally spray it out from the air outlet window 536; by providing a blade cover 535, the blades of the cold fan 531 are protected from damage by external forces. When the blades are damaged or broken, the fragments are easy to fly out. The blade cover 535 can reduce the possibility of the fragments flying out directly, prevent the blade fragments from damaging the air inlet duct 52, and increase additional maintenance costs.

[0038] like Figure 8 As shown, specifically, a screen 5361 is provided on the air outlet window 536. It can effectively prevent dust, debris, etc. from entering the cooling fan 531, thereby protecting the cooling fan 531 from pollution and extending the service life of the cooling fan 531.

[0039] like Figure 1-Figure 5 As shown, in one embodiment, the water cooling structure 6 includes a water inlet pipe 62 and an extension pipe, one end of the water inlet pipe 62 is connected to an external water source, and the other end of the water inlet pipe 62 is connected to the extension pipe, and the extension pipe is inserted through the box 111 and extends to communicate with the water spray pipe 61. The water source flows to the water spray pipe 61 through the extension pipe and is sprayed out.

[0040] like Figure 1-Figure 5 As shown, in one embodiment, the height of the air outlet duct groove 51 and the height of the water spray conduit 61 are both lower than the conveying height of the aluminum profile on the conveying roller 22; a plurality of water spray conduits 61 are provided between two adjacent air outlet duct grooves 51. This prevents the air outlet duct groove 51 or the water spray conduit 61 from directly contacting the aluminum profile being transported, thereby avoiding collisions that affect the transport status of the aluminum profile, and even causing wear or damage to the aluminum profile.

[0041] like Figure 1 and Figure 6As shown, in one embodiment, the material blocking assembly 4 includes a material blocking member 41, a connecting member 42, and a support frame 43 detachably fixed on the fixing seat 23. A conveying channel for the aluminum profile to pass through is formed on the support frame 43. The connecting member 42 is mounted on the top of the support frame 43. The material blocking member 41 is installed on the connecting member 42 and is used to control the opening and closing state of the conveying channel. By providing a conveying channel, the conveying channels at both ends constitute the feed end and the discharge end of the standing wave space, so that the aluminum profile can reciprocate in and out of the standing wave space to complete cooling; by providing a material blocking member 41, the material blocking member 41 can control the opening and closing state of the conveying channel. When the aluminum profile completely enters the standing wave space and needs to be cooled, the material blocking member 41 closes the conveying channel, limits the aluminum profile, and ensures the sealing of the standing wave space, thereby improving the cooling efficiency. When the aluminum profile is completely cooled, the material blocking member 41 opens the conveying channel to continue to transfer and convey the aluminum profile.

[0042] like Figure 6 As shown, in one embodiment, the material blocking member 41 includes an opening and closing cover plate 411, a swing arm 412, a driving block 413, and a mounting block 414 mounted on the connecting member 42, one end of the swing arm 412 is rotatably connected to the mounting block 414, and the other end of the swing arm 412 is rotatably connected to the opening and closing cover plate 411, and the driving block 413 is connected to the swing arm 412 and is used to control the sealing state between the opening and closing cover plate 411 and the conveying channel. By providing the driving block 413, the driving block 413 controls the swing arm 412 to swing, so that the opening and closing cover plate 411 can reciprocate away from and close to the conveying channel, thereby realizing the control of the opening and closing state of the conveying channel, and completing the sealing or opening of the standing wave space.

[0043] Specifically, the outer contour of the opening and closing cover plate 411 matches the outer contour of the conveying channel. The opening and closing cover plate 411 can cover the closed conveying channel, which is convenient for limiting and blocking the aluminum profile, preventing the aluminum profile from moving and leaving the standing wave space during the quenching process, affecting the cooling efficiency.

[0044] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
