Description

Technical Field

[0001] This application relates to the technical field of air cooler manufacturing, and in particular to an air cooler perforated fin collecting device. Background Technology

[0002] As one of the important components of the heat exchanger, the fins in the air cooler are processed by stamping. The coil material is passed through a continuous stamping die to form perforated fins. After forming, the perforated fins are cut and fall into a collection device for stacking. After stacking to a specified quantity, the stacked fins are removed from the collection device for subsequent assembly.

[0003] Existing material collection devices, such as the "simple material collection device" disclosed in CN211437853U, include a material collection plate and material collection pins mounted on the plate. The perforated fins have several through holes. When the fins are stacked on the plate, the material collection pins pass through the through holes to limit their movement. Currently, fins are typically removed from material collection devices manually. Operators apply pressure to the bottom layer of fins on the plate and lift them upwards to remove all the fins. However, this process can be challenging when there are many fins stacked at a high height, making removal difficult in one go. To address this issue, a lifting mechanism has been developed on the plate to raise the fins. Once the bottom layer of fins is lifted to a certain height, the operator can easily unload them.

[0004] However, current lifting mechanisms generally use a screw-type lifting system, where a motor drives a screw to rotate, which in turn raises a lifting plate connected to the screw thread. The lifting plate then lifts the fins. To accommodate the lifting mechanism, the material collection plate must have an additional installation area, increasing the space required for the lifting mechanism and thus increasing the footprint of the site. Utility Model Content

[0005] To facilitate the auxiliary feeding of fins without occupying too much space, this application provides a material collection device for perforated fins of a cold air blower.

[0013] Preferably, it also includes at least two second collecting rods, which are symmetrically distributed on both sides of the first collecting rod. Two guide grooves are symmetrically opened on the outer peripheral wall of the first collecting rod, and the two ends of the lever can extend out from the two guide grooves.

[0014] Preferably, the collecting plate has at least two collecting zones, and each collecting zone is provided with a first collecting rod.

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Example 1

[0034] Figure 1 and Figure 2 The structure of a material collection device for perforated fins of a cold air blower is shown, including a material collection plate 1. The material collection plate 1 is rotatably connected to the base 4 via a drive mechanism. In this embodiment, the material collection plate 1 is divided into two material collection areas 10, left and right. The drive mechanism can drive the material collection plate 1 to rotate 180° to achieve the switching between the two material collection areas 10. Of course, in another embodiment, more than two material collection areas 10 can be provided, and the switching of multiple material collection areas 10 can facilitate the staggered collection and discharge.

[0035] In this embodiment, each collection zone 10 is provided with two first collection rods 2. The two first collection rods 2 are arranged at intervals and one end is fixed on the collection plate 1. The other end has a certain taper so that it can pass through the punch hole of the fin 9.

[0036] The drive mechanism includes a drive component 5 mounted on the base 4, a rack 6 connected to the drive component 5, and a rotating shaft 7 meshing with the rack 6. The drive component 5 is a hydraulic cylinder, with one end of its piston rod connected to one end of the rack 6. The rotating shaft 7 is rotatably connected to the base 4, and its end is connected to the bottom of the collecting plate 1. The rotating shaft 7 also has a gear 71 that meshes with the gear 71. Thus, when the rack 6 is driven to slide by the drive component 5, it can drive the rotating shaft 7 to rotate, thereby causing the collecting plate 1 to rotate relative to the base 4. The base 4 is mounted on the ground and fixed by fasteners.

[0037] In order to improve the guiding performance of rack 6, a limiting seat 41 is also provided on base 4. The limiting seat 41 is located on one side of rotating shaft 7, and the smooth side of rack 6 abuts against the limiting seat 41. Thus, when rack 6 moves, the radial deviation of rack 6 in the sliding direction can be reduced by abutting against the limiting seat 41.

[0038] The base 4 is also equipped with multiple auxiliary guide wheels 8, which abut against the bottom of the collection plate 1. While providing auxiliary support, they can also improve the smoothness of the rotation of the collection plate 1.

[0039] See also Figure 3 and Figure 4A chain-type window opener 3 is also installed at the bottom of the collection plate 1 corresponding to the collection area 10. In this embodiment, the chain-type window opener 3 is a double chain-type window opener 3, which includes a mounting box 31 and two chain-type window openers 3 with the same structure housed in the mounting box 31. The mounting box 31 has a mounting cavity 311 for housing the two chain-type window openers 3. The mounting box 31 is fixed to the bottom of the collection plate 1 by fasteners.

[0040] The chain-type window opener 3 includes a motor 32, a reducer 33 connected to the motor 32, and a lifting chain 34 connected to the reduction zone. The specific telescopic structure of the lifting chain 34 is prior art; please refer to the patent in publication number CN202380877U for details, which will not be elaborated here. In short, the motor 32 outputs torque through the reducer 33, driving the sprocket 35 to rotate. The sprocket 35 then moves the lifting chain 34, which is confined within the telescopic track for guided sliding. The reducer 33 is a multi-stage gear reducer 33, and one end of the sprocket 35 meshes with the reducer 33 to achieve drive.

[0041] The lifting chain 34 extends from the opening of the mounting box 31. The collection plate 1 has a guide opening 11 for the lifting chain 34 to pass through when it extends. A lever 36 is connected to the top of the lifting chain 34. A sliding cavity 21 is provided inside the first collection rod 2, which can guide the lifting chain 34 to slide when it extends. A guide groove 22 communicating with the sliding cavity 21 is provided on one side of the outer peripheral wall of the first collection rod 2. Both the guide groove 22 and the sliding cavity 21 are connected to the guide opening 11 of the collection plate 1. Thus, when the lever 36 is driven to slide by the lifting chain 34, it can extend out from the guide groove 22 and act on the fins 9 stacked on the collection plate 1 to lift the fins 9.

[0042] It is worth noting that in this embodiment, the guide grooves 22 of the two first collecting rods 2 are arranged opposite to each other, so that when the two levers 36 slide, they can act on both sides of the bottom of the fin 9, improving the stability when lifting the fin 9. In addition, the lifting chain 34 can remain vertical when straightened because the adjacent links are mutually abutting and limiting on one side, and can achieve stable lifting under the guidance of the sliding cavity 21. Furthermore, the traditional chain-type window opener 3 can have a thrust of 700N, equivalent to 71Kg, while the weight of a single fin 9 is only between 1-2Kg. Therefore, two chain-type window openers 3 can easily lift approximately 70-140 fins 9. Furthermore, in this embodiment, the sliding cavity 21 is not fully connected to the first collecting rod 2. This is to maintain the strength of the first collecting rod 2 itself, and the lifting of the fin 9 does not need to be completely detached from the first collecting rod 2. It only needs to be lifted a certain height away from the collecting plate 1 so that it can be easily removed by the operator as a whole, thereby achieving the purpose of assisting in material feeding. Example 2

[0043] See also Figure 5 and Figure 6 A material collection device for perforated fins of an air cooler, differing from Embodiment 1, is provided in that each collection zone 10 has a first material collection rod 2 and two second material collection rods 20 located on both sides of the first material collection rod 2, with the two second material collection rods 20 serving as auxiliary components. In this embodiment, only one chain-type window opener 3 is provided at the bottom of each collection zone 10. The difference is that the lever 36 extends outward from both sides of the end of the lifting chain 34 with equal extension lengths. Two guide grooves 22 communicating with the sliding cavity 21 are symmetrically provided on the outer peripheral wall of the first material collection rod 2. The two ends of the lever 36 can extend out from the sliding cavity 21 and respectively from the corresponding guide groove 22, so that the lifting force on the fin 9 is balanced.

[0044] Furthermore, the length of the baffle 36 in both Embodiment 1 and Embodiment 2 is set so that it will not enter the punch hole of the fin 9 and thus fail to act on the main body of the fin 9.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
