Description

Technical Field

[0001] This utility model particularly relates to a cooling device for aluminum profile processing. Background Technology

[0002] In continuous aluminum profile production lines (especially in the cooling section after anodizing or spraying), the profiles exiting the tank are at high temperatures and are heavy. Cantilever arms or crossbars are used to suspend shelves within the cooling channels of the cooling equipment. These shelves hold the aluminum profiles. When the aluminum profiles are overloaded, the shelves and crossbars undergo plastic bending. If the bending is excessive, it can lead to uneven distance between the profiles and the cooling vents, resulting in insufficient cooling; in severe cases, it can cause the entire shelf to be scrapped or even damage the equipment. Current technology commonly uses a method of "laying pressure sensors throughout the base area." This method embeds multiple pressure sensors evenly into the base or support, indirectly calculating the load from the sum of multiple reaction forces. However, pressure sensors require extensive installation, resulting in complex wiring and high costs. Furthermore, it only reflects the "overall weight" and cannot directly provide the "actual deflection of the crossbar." When the crossbar partially yields but the weight does not exceed the limit, the system cannot provide a timely warning. Utility Model Content

[0009] Two crossbars are fixedly installed at both ends of the arc-shaped support.

[0010] A shelf is provided between the two crossbars and within the cooling channel, and the shelf is provided with multiple sets of limiting blocks for limiting the aluminum profiles;

[0011] A through-beam sensor has its transmitter and receiver positioned at opposite ends of the crossbar. The transmitter outputs a pulsed light beam to the receiver to keep the receiver in a conducting state, and the receiver switches to a turning-off state when no pulsed light beam is detected.

[0012] Preferably, the shelf includes a connecting part with an elliptical cross-section; at least one ventilation slot is provided in the connecting part, and a top ventilation hole and a bottom ventilation hole communicating with the ventilation slot are provided at the top and bottom of the connecting part, respectively.

[0013] Preferably, the limiting blocks are provided in multiple groups, each group including at least three limiting blocks arranged along the width direction of the shelf; the limiting blocks are provided with arc-shaped limiting portions for accommodating aluminum profiles, so that the middle and both ends of a single aluminum profile can be respectively limited within the arc-shaped limiting portions of the three limiting blocks in the same group.

[0014] Preferably, the cold source assembly includes a spiral coil, which is wound and disposed within the cooling channel, and a cooling medium flows through the spiral coil.

It directly detects "deflection" rather than "weight," resulting in high sensitivity and fast response. Only one pair of sensors is needed to cover the entire crossbar, simplifying wiring and significantly reducing maintenance. Attached Figure Description

[0032] The positioning cylinder 3 is fixedly installed at the upper end of the arc-shaped support 2. A cooling channel 4 is formed inside the positioning cylinder 3, and a cold source assembly is installed inside the cooling channel 4.

[0034] A shelf 7 is arranged between the two crossbars 6 and within the cooling channel 4. The shelf 7 is provided with multiple sets of limiting blocks 8 for limiting the aluminum profiles.

[0035] The through-beam sensor has a transmitter 91 and a receiver 92 respectively disposed at both ends of the crossbar 6. The transmitter 91 is used to output a pulse beam to the receiver 92 to keep the receiver 92 in a conducting state; and the receiver 92 is used to switch to a turning-off state when no pulse beam illumination is detected.

[0036] Furthermore, the shelf 7 includes a connecting part 71, the cross-section of which is elliptical; at least one ventilation groove 72 is provided in the connecting part 71, and a top ventilation hole 73 and a bottom ventilation hole 74 communicating with the ventilation groove 72 are respectively provided at the top and bottom of the connecting part 71.

[0037] Furthermore, the limiting block 8 is provided in multiple groups, each group including at least three limiting blocks 8 arranged along the width direction of the shelf 7; the limiting block 8 is provided with an arc-shaped limiting part 81 for accommodating aluminum profiles, so that the middle and both ends of a single aluminum profile can be respectively limited within the arc-shaped limiting parts 81 of the three limiting blocks 8 in the same group.

[0038] Furthermore, the cold source assembly includes a spiral coil 51, which is coiled within the cooling channel 4, and a cooling medium flows through the spiral coil 51.

[0039] Furthermore, the cooling medium is cold air.

[0040] Furthermore, a U-shaped groove 21 is provided on the arc-shaped support 2, and an anti-detachment part 61 extending radially outward is provided at the end of the crossbar 6, the anti-detachment part 61 being confined within the U-shaped groove 21.

[0041] Furthermore, the through-beam sensor is electrically connected to a buzzer.

[0042] The working principle of this utility model is as follows:

[0043] like Figure 1-3As shown, the cooling equipment for aluminum profile processing in this embodiment includes a base 1 and an arc-shaped support 2. The arc-shaped support 2 is fixed to the base 1 by bolts. A positioning cylinder 3 is fixedly disposed at the upper end of the arc-shaped support 2, and a cooling channel 4 is formed inside the positioning cylinder 3. As in embodiment 1, the cold source assembly can be composed of a spiral coil 51. The spiral coil 51 is fixed in the cooling channel 4 by a bracket. When the cooling source is cold air, the inlet 51a and outlet 51b of the spiral coil 51 are respectively connected to an external cold air fan 1-1 to circulate cold air. The two ends of the shelf 7 are fixed to the crossbar 6 by bolts and are located in the cooling channel 4. The shelf 7 includes an elliptical connecting part 71. A ventilation groove 72 is provided in the connecting part 71. A top ventilation hole 73 and a bottom ventilation hole 74 are opened at the top and bottom of the connecting part 71 respectively. Cold air can circulate in the ventilation groove 72 to improve cooling uniformity. The transmitting end 91 and the receiving end 92 of the through-beam sensor are respectively locked to the outermost ends of the two crossbars 6 so that their axes are in the same straight line. In this state, receiver 92 continuously receives the pulsed light beam and remains conductive. The buzzer, electrically connected to the through-beam sensor, will not sound. When the total weight of the aluminum profiles on shelf 7 exceeds the design threshold, the crossbar 6 deflects downwards due to bending moment. When the deflection reaches or exceeds 2mm, the crossbar 6 blocks the pulsed light beam, and receiver 92 momentarily fails to detect a valid light signal. Its internal transistor immediately switches from conductive to non-conductive. The buzzer circuit then closes and becomes energized, immediately emitting a continuous audible and visual alarm to remind operators to reduce load or stop the machine for maintenance, thus effectively preventing further deformation or damage to the crossbar 6.

[0044] Based on the above technical solution, the limiting block 8 can be installed on the shelf 7 by T-bolts, with three blocks in each group arranged along the width direction. An arc-shaped limiting part 81 is machined on the limiting block 8, and the aluminum profile 100 is placed in it to achieve three-point support.

[0045] Based on the above technical solution, a U-shaped groove 21 is provided on the arc-shaped support part 2, and a radially outwardly extending anti-detachment part 61 is provided at the end of the crossbar 6; the anti-detachment part 61 is confined within the U-shaped groove 21 to restrict the axial movement of the crossbar 6. This design provides a mechanical stop in the axial (left-right) direction of the crossbar 6, preventing the crossbar 6 from slipping outwards during impact or thermal expansion and contraction, resulting in a high safety factor.

[0046] This design is particularly suitable for aluminum profile anodizing production lines. After anodizing, the profiles are at a high temperature, and the oxide film on their surface is unstable. If natural cooling takes too long, it will lead to low production efficiency and uneven coloring of the profiles. Therefore, placing the anodized aluminum profiles in rack 7 for rapid cooling can save production time.

[0047] This invention innovatively incorporates through-beam sensors at both ends of a crossbar, locking the transmitter and receiver to the ends of the two crossbars respectively. The beam of light shines directly along the axis of the crossbar 6. When the crossbar 6 is not deformed, the beam is unobstructed, and the receiver remains conductive. When the crossbar bends downward by ≥2mm due to overload, the beam is interrupted, the receiver immediately shuts off, and a buzzer alarm is triggered. It directly detects "deflection" rather than "weight," resulting in high sensitivity and fast response. Only one pair of sensors is needed to cover the entire crossbar, simplifying wiring and significantly reducing maintenance.

[0048] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
