Description
Technical Field
[0001] This utility model relates to the field of fin technology, specifically to a material collection device for forming fins. Background Technology
[0002] Air conditioner fins are an important component inside air conditioning units. By increasing the surface area, air conditioner fins can increase the contact area with indoor air, thereby accelerating heat conduction and dissipation, and improving the heat exchange efficiency of the air conditioner. The angle of the air conditioner fins can be adjusted to change the direction and speed of airflow, so that the air can be evenly distributed throughout the room, achieving better air circulation and comfort. The angle adjustment of the air conditioner fins can also be used to control the direction and range of cold or hot air output, helping to regulate indoor temperature and make the temperature distribution more uniform.
[0003] Air conditioner fins have multiple process holes for heat exchange tubes to pass through, and protrusions are provided around the process holes. The forming process of air conditioner fins is generally completed by aluminum foil passing through a forming mold assembly. The feeding mechanism feeds the aluminum foil into the forming mold assembly, and the forming mold assembly performs processes such as traction, stretching, punching, flanging, and cutting on the aluminum foil to form fins in one step.
[0004] The inventors of this application have discovered that because the formed fins are thin and light, they are prone to deformation and indentation during the grasping process. Therefore, how to collect the formed fins is a technical problem that urgently needs to be solved by technicians in the industry. Summary of the Invention
[0005] The purpose of this invention is to provide a material collection device for shaped fins to solve the problems mentioned in the background art.
[0006] This utility model provides a stripping and collection device for formed fins, including: a frame support, a blower, a collection box, a stripping plate, a collection rack, and a controller; The bottom of the receiving box is open; The receiving box is mounted on the frame support, and the stripping plate is mounted on the receiving box to seal the bottom of the receiving box. The stripping plate is provided with suction holes, which are connected to the inner cavity of the receiving box. The exhaust fan is mounted on the frame support and is connected to the inner cavity of the receiving box through an exhaust pipe, which is equipped with an exhaust valve. The receiving rack includes: a base and a receiving rod; The base is mounted on the frame bracket, and multiple material receiving rods are vertically mounted on the base; The fins are pushed onto the stripping plate by the forming equipment. The exhaust fan is used to adsorb the fins onto the stripping plate. When the exhaust valve is opened, it is used to depressurize the inner cavity of the receiving box, so that the adsorbed fins fall off and pass through the receiving rod. The exhaust fan and the exhaust valve are electrically connected to the controller.
[0007] Based on the above scheme, the material collection device for forming fins of this utility model comprises a frame support, an exhaust fan, a receiving box, a stripping plate, a receiving rack, and a controller. The receiving box is mounted on the frame support, and the stripping plate is mounted on the receiving box. The stripping plate has suction holes communicating with the inner cavity of the receiving box. The exhaust fan is mounted on the frame support and communicates with the inner cavity of the receiving box through an exhaust pipe equipped with an exhaust valve. The receiving rack includes a base and receiving rods. The base is mounted on the frame support, and multiple receiving rods are mounted on the base. In this material collection device for forming fins, the forming equipment slowly pushes the fins to the bottom of the stripping plate. The exhaust fan causes the formed fins to be adsorbed onto the stripping plate. After the fins are completely delivered to the stripping plate, the controller shuts off the exhaust fan and simultaneously opens the exhaust valve, depressurizing the inner cavity of the receiving box. The adsorbed fins fall off under gravity, and the process holes of the fins pass through the receiving rods, causing the fins to fall onto the receiving rack. The fins are adsorbed onto the stripping plate by negative pressure and fall when the pressure is released. This prevents deformation and indentation during the stripping and collection process, ensuring the fin qualification rate.
[0008] In one feasible solution, the stripping plate is provided with a guide groove; The guide groove is used for embedding the protrusions of the fins.
[0009] One feasible solution also includes: a pusher cylinder; The pushing cylinder is mounted on the receiving box and is electrically connected to the controller; The stripping plate includes: a fixed plate and a movable plate; The fixed plate is mounted on the receiving box, and the movable plate is connected to the pushing cylinder. The pushing cylinder is used to drive the movable plate to rise and fall. When the movable plate descends, it pushes the fins down. When the movable plate rises, it seals the receiving box.
[0010] In one feasible solution, the receiving rack further includes: a movable seat; The base is provided with a sliding groove, the movable seat is slidably disposed in the sliding groove, and the receiving rod is disposed on the movable seat.
[0011] In one feasible solution, the movable seat includes: an upper connecting plate and a lower connecting plate; The upper connecting plate and the lower connecting plate are arranged parallel to each other and connected by a connecting rod; The upper connecting plate is provided with a through hole, the lower connecting plate is provided with a receiving groove, and the receiving rod passes through the through hole and is embedded in the receiving groove.
[0012] In one feasible solution, the movable seat further includes: a locking bolt; The locking bolt engages with the lower connecting plate, and when tightened, the locking bolt abuts against the base to fix the lower connecting plate.

[0022] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.
[0023] As described in the background section of this application, see [link to relevant documentation]. Figure 1 and Figure 2 As shown, the fin 100 has multiple process holes 110 for heat exchange tubes to pass through. The process holes 110 are arranged in multiple rows, and flanged protrusions 110 are provided around the process holes 110. The forming process of the fin 100 is generally completed by aluminum foil through a forming mold assembly. The feeding mechanism feeds the aluminum foil into the forming mold assembly, and the forming mold assembly performs processes such as traction, stretching, punching, flanging, and cutting on the aluminum foil to form the fin in one step.
[0024] The inventors of this application have discovered that because the formed fins are thin and light, they are prone to deformation and indentation during the grasping process. Therefore, how to better collect the formed fins is a technical problem that urgently needs to be solved by technicians in the industry.
[0025] To address the aforementioned problems, the inventors of this application have proposed a technical solution, the specific embodiments of which are as follows: Figure 3 This is a schematic diagram of the material collection device for forming fins in an embodiment of the present invention. Figure 4 As described in the embodiments of this utility model Figure 3 Enlarged view of point A in the image. Figure 5 As described in the embodiments of this utility model Figure 3 Enlarged view of point B in the image. Figure 6 This is a side view of the stripping plate in an embodiment of the present invention.
[0026] like Figures 3 to 6 As shown, the material collection device for forming fins in this embodiment includes: a frame support 1, a blower 2, a material collection box 3, a material removal plate 4, a material collection rack 5, and a controller.
[0027] The receiving box 3 is rectangular in shape, and the bottom of the receiving box 3 is open.
[0028] The frame-type support 1 is located at the rear end of the fin forming equipment 200, adjacent to the fin forming equipment 200 of the fin 100. The receiving box 3 is located on the frame-type support 1, and the stripping plate 4 is detachably located at the bottom of the receiving box 3 by connecting bolts. The stripping plate 4 is sealed to the receiving box 3, so that the bottom opening of the receiving box 3 is sealed.
[0029] The stripping plate 4 is densely covered with through suction holes 41, and the suction holes 41 of the stripping plate 4 are connected to the inner cavity of the receiving box 3.
[0030] The exhaust fan 2 is mounted on the frame bracket 1, located above the receiving box 3. The exhaust port of the exhaust fan 2 is connected to the top of the receiving box 3 through the exhaust pipe 21, and the exhaust pipe 21 is connected to the inner cavity of the receiving box 3.
[0031] An exhaust valve 22 is provided on the exhaust pipe 21. When the exhaust valve 22 is opened, it connects the inner cavity of the receiving box 3 with the outside.
[0032] The receiving rack 5 includes: a base 51 and a receiving rod 52.
[0033] The base 51 is mounted on the bottom plate of the frame bracket 1.
[0034] Multiple receiving rods 52 are provided, and the multiple receiving rods 52 are vertically arranged on the base 51. The multiple receiving rods 52 are arranged in two rows. The top of the receiving rod 52 is adjacent to the bottom surface of the stripping plate 4, and a slight gap is left between the receiving rod 52 and the stripping plate 4.
[0035] The exhaust fan 2 and the exhaust valve 22 are electrically connected to the controller.
[0036] In this embodiment, the fin stripping and collecting device is arranged adjacent to the fin forming equipment. After the forming is completed on the forming equipment, the forming equipment slowly pushes the fin along the bottom surface of the stripping plate to the area below the stripping plate. During the pushing process, the exhaust fan draws in the vacuum negative pressure inside the receiving box, causing the formed fin to be adsorbed onto the bottom surface of the stripping plate.
[0037] After the formed fins are completely delivered to the stripper plate, the controller shuts off the exhaust fan and opens the exhaust valve at the same time, depressurizing the inner cavity of the receiving box. The adsorbed fins fall off under the action of gravity. The two process holes of the fins are inserted through the two receiving rods, causing the fins to fall onto the receiving rack.
[0038] Repeat the above process, and the shaped fins will continue to fall and stack on the receiving rod of the receiving rack. Once the appropriate height is reached, replace the receiving rack to continue collecting the shaped fins.
[0039] As can be seen from the above, the material collection device for forming fins in this embodiment comprises a frame support, an exhaust fan, a receiving box, a stripping plate, a receiving rack, and a controller. The receiving box is mounted on the frame support, and the stripping plate is mounted on the receiving box. The stripping plate has suction holes communicating with the inner cavity of the receiving box. The exhaust fan is mounted on the frame support and communicates with the inner cavity of the receiving box through an exhaust pipe equipped with an exhaust valve. The receiving rack includes a base and receiving rods. The base is mounted on the frame support, and multiple receiving rods are mounted on the base. In this material collection device for forming fins, the forming equipment slowly pushes the fins to the bottom of the stripping plate. The exhaust fan causes the formed fins to be adsorbed onto the stripping plate. After the fins are completely delivered to the stripping plate, the controller shuts off the exhaust fan and simultaneously opens the exhaust valve, depressurizing the inner cavity of the receiving box. The adsorbed fins fall off under gravity, and the process holes of the fins pass through the receiving rods, causing the fins to fall onto the receiving rack. The fins are adsorbed onto the stripping plate by negative pressure and fall when the pressure is released. This prevents deformation and indentation during the stripping and collection process, ensuring the fin qualification rate.
[0040] Optional, such as Figure 6As shown, in this embodiment, the material collection device for forming fins has a guide groove 42 on the bottom surface of the material collection plate 4.
[0041] The guide channel 42 has multiple channels, and the width of the guide channel 42 corresponds to the protrusions 120 around the process holes of the fin 100. When the fin 100 is pushed to the stripper plate 4, the protrusions 120 of the fin 100 are embedded in the guide channel 42 of the stripper plate 4 and move along the guide channel 42 to the left side of the stripper plate 4. At the same time, it is attracted to the stripper plate 4 to prevent the fin 100 from shifting during movement. When the fin stops moving in place, the process holes 110 at both ends of the fin 100 are opposite to the two receiving rods 52. When falling, the receiving rods 52 pass into the process holes of the fin.
[0042] Optionally, the material collection device for forming fins in this embodiment further includes a pusher cylinder 6.
[0043] There are four pusher cylinders 6, which are installed on the receiving box 3 on the front and rear sides of the receiving box 3. The pusher cylinders 6 are electrically connected to the controller.
[0044] The stripping plate 4 includes a fixed plate 401 and a movable plate 402.
[0045] The fixed plate 401 of the stripping plate 4 is fixed on the receiving box 3. The two ends of the movable plate 402 are connected to the telescopic rod of the pushing cylinder 6. The extension and retraction of the telescopic rod of the pushing cylinder 6 drives the movable plate 402 to rise and fall. When the movable plate 402 descends, it pushes the fins 100 adsorbed on the stripping plate 4 to fall. When the movable plate 402 rises, it seals the inner cavity of the receiving box 3.
[0046] In this embodiment, the stripping plate seals the inner cavity of the receiving box, and the fins are adsorbed onto the stripping plate when the exhaust fan is running. When the exhaust valve is opened, the inner cavity of the receiving box is depressurized and the fins fall. At this time, the extension rod of the pusher cylinder extends and pushes the fins adsorbed onto the stripping plate to fall, preventing the fins from falling off by themselves due to being too tightly adsorbed.
[0047] Optionally, the material collection device for forming fins in this embodiment, the material collection rack 5, further includes: a movable seat 53.
[0048] The base 51 of the receiving rack 5 is provided with a groove 511. The movable seat 53 is set on the base 51 and can be slidably embedded in the groove 511 of the base 51. The receiving rod 52 is set on the movable seat 53 to facilitate the adjustment of the distance between the two rows of receiving rods 52 to accommodate the collection of fins of different specifications.
[0049] Furthermore, in this embodiment, the material collection device for forming fins includes an upper connecting plate 531 and a lower connecting plate 532.
[0050] The upper connecting plate 531 and the lower connecting plate 532 are arranged at intervals and parallel to each other. The upper connecting plate 531 and the lower connecting plate 532 are connected by a connecting rod. The lower connecting plate 532 is slidably mounted on the base 51.
[0051] The upper connecting plate 531 has a through hole, and the lower connecting plate 532 has a receiving groove. The receiving rod 52 passes through the through hole of the upper connecting plate 531, and the bottom end of the receiving rod 52 is inserted into the receiving groove of the lower connecting plate 532, which facilitates the fixing of the receiving rod 52 on the movable seat 53.
[0052] Furthermore, in this embodiment, the movable seat 53 of the material collection device for forming fins also includes a locking bolt 533.
[0053] The locking bolt 533 engages with the threaded hole of the lower connecting plate 532. When the locking bolt 533 is tightened, it abuts against the base 51, fixing the lower connecting plate 532 to the base 51 and preventing the movable seat 53 from moving during use.
[0054] Optionally, in this embodiment, the top end of the material collection rod 52 of the material collection device for forming fins is conical, which facilitates the insertion of the fins 100.
[0055] Optional, such as Figure 3 and Figure 5 As shown, in this embodiment, the material collection device for forming fins has a guide rail 11 on the bottom plate of the frame bracket 1, and the bottom plate of the frame bracket 1 has multiple workstations for placing bases 51.
[0056] The base 51 of the receiving rack 5 is slidably mounted on the guide rail 11 of the frame bracket 1. The receiving rack 5 can be switched between multiple workstations of the frame bracket 1, so that the receiving rack 5 can be quickly replaced.
[0057] In this embodiment, the base plate of the frame bracket is provided with multiple workstations. After the fins on the receiving rack reach the preset height, the receiving rack is moved to an empty workstation and a spare receiving rack is moved to the receiving workstation, so as to realize the rapid replacement of the receiving rack.
[0058] Furthermore, in this embodiment, the material collection device for forming fins includes two exhaust fans 2.
[0059] Two exhaust fans 2 are installed on the top of the frame bracket 1, located on the left and right sides of the receiving box 3. The two exhaust fans 2 are connected to the inner cavity of the receiving box 3 through exhaust pipes 21 respectively, and exhaust valves 22 are provided on both exhaust pipes 21.
[0060] Two exhaust fans are used to make the pressure inside the receiving box more uniform, avoiding fin deformation caused by uneven local pressure.

[0062] Furthermore, "above," "on top of," and "above" the first feature in relation to the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "under," and "beneath" the first feature in relation to the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
