Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning manufacturing, in particular to a fin material receiving device for a heat exchanger. Background Art

[0002] Heat exchanger fins are important components of the tube-fin heat exchanger in air conditioning devices. Their main function is to increase the heat exchange area and improve the heat exchange efficiency. Heat exchanger fins are generally made by stamping fin dies. Material splicing is the process of gathering materials after all the punching and cutting of the fin die is completed. In order to facilitate the subsequent tube threading and tube expansion, the fins must be stacked one by one and put on the splicing device during the gathering process.

[0003] The material receiving device generally includes a material receiving trolley and a material receiving frame installed on the material receiving trolley. The material receiving frame is provided with a material receiving needle. When receiving the material, the fins are stacked one by one and inserted on the material receiving needle to form a fin pile. After the material receiving is completed, the auxiliary material picking needle is inserted, and the material receiving trolley is pushed to the unloading station. Through the automatic unloading equipment, the perforated support plate on the material receiving frame and the fin pile are separated from the material receiving needle, and then rotated 90° to flip and unload.

[0004] When the fin is moved out of the receiving trolley, since the lower end of the auxiliary material picking needle is basically flush with the lowest fin of the receiving device, after the fin is taken out of the receiving trolley, the lowest fin is easy to fall off the auxiliary material picking needle, affecting the normal progress of subsequent processes.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0006] In response to the problems pointed out in the background technology, the present application provides a heat exchanger fin receiving device, which is provided with a telescopic support plate that can move up and down, and an auxiliary material picking needle is supported on the telescopic support plate. When moving materials, the auxiliary material picking needle can move downward and extend out of the fin stack for a certain distance to ensure that the lowest fin is not easy to fall off the auxiliary material picking needle; at the same time, when receiving materials, the telescopic support plate is close to the upper support plate and supported on the platform of the material receiving trolley, which can ensure the horizontality of the upper support plate and make the material picking needle not easy to deflect.

[0007] In order to achieve the above-mentioned utility model purpose, the utility model adopts the following technical solutions:

[0008] In some embodiments of the present application, a heat exchanger fin receiving device is provided, comprising a receiving trolley, a receiving rack assembly and a moving rack assembly;

At least one guide rod is provided at each end of the telescopic support plate to connect the telescopic support plate and guide the sliding movement.

[0017] In some embodiments of the present application, a first height adjustment mechanism is provided between the upper support plate and the material moving rack for adjusting the height of the upper support plate. By adjusting the height of the upper support plate, the distance between the upper support plate and the material receiving base can be adjusted, and the height of the fins can be adjusted.

[0018] In some embodiments of the present application, a second height adjustment mechanism is provided at the bottom of the material moving rack, and the second height adjustment mechanism is provided between the material moving rack and the material receiving trolley, and is used to adjust the height of the material moving rack. By adjusting the height of the material moving rack, the distance between the upper support plate and the material receiving base can be assisted to adjust the height of the fins.

[0019] In some embodiments of the present application, the second height adjustment mechanism includes a support foot and a second adjustment bolt, and the support foot is fixed to the bottom of the material moving rack through the second adjustment bolt.

[0020] In some embodiments of the present application, a material moving sleeve is provided on both sides of the material moving rack, and the material moving sleeve is used to insert a driving member when moving materials. A first positioning structure protruding outward is provided on the end of the material moving sleeve that is inserted into the driving member. When the driving member is inserted into the material moving sleeve, the first positioning structure can play a positioning role, and can avoid touching other positions of the material receiving trolley, thereby avoiding causing alarms and damaging equipment.

[0021] In some embodiments of the present application, a second positioning structure is provided at the bottom of the material transfer rack, and the second positioning structure is used to cooperate with the material receiving trolley for positioning. When the material transfer rack assembly is returned to its original position, the second positioning structure enables the material transfer rack to be accurately placed on the material receiving trolley.

In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0061] like Figure 1-Figure 10 As shown, some embodiments of the present application provide a heat exchanger fin connecting device, which is used for connecting heat exchanger fins.

[0062] After the fin processing (such as stamping, rolling, etc.) is completed, the fins 300 are stacked one by one and inserted into the heat exchanger fin material receiving device to facilitate the subsequent tube insertion and tube expansion.

[0063] The heat exchanger fin receiving device includes a receiving trolley (not shown in the figure) and a receiving rack assembly 100 .

[0064] The material receiving frame assembly 100 includes a material receiving base 110 and a plurality of material receiving needles 120 vertically mounted on the material receiving base 110 .

[0065] The material receiving base 110 is fixed on the material receiving trolley.

[0066] When the stamping of the fin die is completed, the material receiving trolley can be moved to the material receiving station to collect and receive the finished fins 300; after the material receiving is completed, the material receiving trolley can be pushed to transfer the fin stack to the subsequent unloading station.

[0067] The receiving pins 120 are used to accurately receive and support the fins after the fin processing is completed to prevent the fins from falling or deforming.

[0068] The splicing needle 120 can be adjusted according to the different lengths and specifications of the fins to meet the splicing requirements of fins of various sizes, thereby ensuring the versatility and flexibility of the splicing process.

[0069] The pick-up pins 120 are arranged reasonably so that the fins are kept neat and orderly during the pick-up process. In some embodiments of the present application, the pick-up pins 120 are arranged in two rows, and the adjacent pick-up pins 120 in each row are arranged in a staggered manner.

[0070] The heat exchanger fin receiving device also includes a material moving rack assembly 200 .

[0071] The material moving rack assembly 200 is located on the upper side of the material receiving base 110 and can be detachably arranged on the material receiving trolley. After the material receiving is completed, the material moving rack assembly 200 can be removed from the material receiving trolley as a whole.

[0072] Specifically, see Figure 3-Figure 10 The material moving rack assembly 200 includes a material moving rack 210 , an upper support plate 230 and a telescopic support plate 240 .

[0073] The material moving rack 210 is used to be supported on the material receiving trolley and is a mounting base for the upper support plate 230 and the telescopic support plate 240 .

[0074] Material shifting sleeves 220 are respectively arranged on both sides of the material shifting frame 210. When unloading, the material shifting frame assembly 200 can be transferred by inserting the driving member on the automatic unloading device into the material shifting sleeve 220.

[0075] The material moving sleeve 220 and the material moving frame 210 may be an integral structure or a separate structure.

[0076] The upper support plate 230 is fixed on the material transfer rack 210. Figure 7 The upper support plate 230 is provided with a first through hole 231 through which the receiving needle 120 can pass.

[0077] The upper support plate 230 is arranged horizontally, and the material receiving needles 120 on the material receiving base 110 vertically pass through the upper support plate 230 . The received fins pass through the material receiving needles 120 and are supported on the upper support plate 230 .

[0078] The upper support plate 230 is also provided with a second through hole 232 through which the auxiliary material taking needle 400 can pass.

[0079] After the material receiving process is completed, in order to facilitate the subsequent unloading operation, auxiliary material extraction needles 400 are pre-installed on each stack of fins. The purpose of these auxiliary material extraction needles 400 is to effectively carry and organize the fins after the fin stack is separated from the material receiving device, ensuring that the fins are transferred or collected in an orderly and stable manner.

[0080] The telescopic support plate 240 is horizontally arranged below the upper support plate 230. Figure 8 As shown, the telescopic support plate 240 is provided with a third through hole 241 for the receiving needle 120 to pass through.

[0081] like Fig. 9 As shown, the joining needle 120 can vertically pass through the telescopic support plate 240 and the upper support plate 230 .

[0082] The auxiliary material extraction needle 400 is inserted into the fin stack from top to bottom, passes through the second through hole 232 of the upper support plate 230, and can be supported on the telescopic support plate 240.

[0083] In the present application, the telescopic support plate 240 is connected to the upper support plate 230 through a guide structure and can move up and down relative to the upper support plate 230. Figure 4 and Figure 5 As shown, the telescopic support plate 240 can move up and down relative to the upper support plate 230.

[0084] See also Figure 1 When the material transfer rack assembly 200 is placed on the material receiving trolley, the telescopic support plate 240 is arranged close to the upper support plate 230 and supported on the platform of the material receiving trolley.

[0085] The working process of the heat exchanger fin receiving device of the present application is as follows:

[0086] When receiving the material, the receiving trolley is pushed to the receiving station. After the fin processing is completed, it passes through the receiving needle 120 and falls onto the upper support plate 230. Figure 1 shown.

[0087] When the material connection is completed and the fin stack needs to be moved, an auxiliary material removal needle 400 (such as Fig. 9 Insert the auxiliary material removal needle 400 as shown), and then push the material receiving trolley to the unloading station.

[0088] At the unloading station, the material transfer rack 210 can be driven to move upward by the automatic unloading device. Figure 2 As shown in the figure (to simplify the drawing, the auxiliary material picking needle 400 is not shown in the figure), during the ascending process of the material moving rack 210, the fin stack on the upper support plate 230 gradually separates from the material receiving needle 120, and at the same time, the telescopic support plate 240 moves downward relative to the upper support plate 230 under the action of gravity. At this time, the auxiliary material picking needle 400 also moves downward together with the telescopic support plate 240 under the action of gravity, so that the auxiliary material picking needle 400 extends downward from the bottom fin for a distance (the state of the auxiliary material picking needle 400 can be seen in Fig.10 ).

[0089] When the telescopic support plate 240 moves to the lowest position, it stops moving, and then rises together with the material moving rack 210 and the upper support plate 230 with the fin stack and the auxiliary material taking needle 400 until the material moving rack assembly 200 is completely separated from the material receiving needle 120.

[0090] like Fig.10 As shown, after the material moving rack assembly 200 and the fin stack thereon are completely separated from the material receiving needle 120, the automatic unloading device turns the material moving rack assembly 200 and the fin stack 90 degrees, and the fin stack and the auxiliary material taking needle 400 can be removed together.

[0091] Since the auxiliary material extraction needle 400 extends a distance from the fin stack, the fin is not easy to fall off the auxiliary material extraction needle 400. At the same time, both ends of the auxiliary material extraction needle 400 are bald. After the fins are spliced, the auxiliary material extraction needle 400 can be inserted from one end and directly ejected from the other end when inserting the tube, without manually pulling out the auxiliary material extraction steel needle, simplifying the operation process.

[0092] In addition, the telescopic support plate 240 is designed as a liftable structure. When receiving materials, the telescopic support plate 240 can be supported on the platform of the material receiving trolley, ensuring the horizontality of the upper support plate 230. When receiving materials, the material receiving needle 120 will not be deflected due to the deflection of the fins, affecting the subsequent material receiving.

[0093] The above-mentioned heat exchanger fin receiving device, by arranging a retractable retractable support plate 240 on the lower side of the upper support plate 230, can make the auxiliary material picking needle 400 move downward and extend a certain distance from the fin stack when moving materials, to ensure that the lowest fin is not easy to fall off from the auxiliary material picking needle 400, thereby improving the stability of the fin during the material picking process; at the same time, when receiving the material, the retractable support plate 240 is close to the upper support plate 230 and supported on the platform of the material receiving trolley, which can ensure the horizontality of the upper support plate 230 during the material receiving process, so that the material receiving needle 120 is not easy to deflect, thereby reducing the fin receiving failure rate caused by the deflection of the material receiving needle 120 and improving work efficiency.

[0094] In some embodiments of the present application, Figure 5 and Figure 6 As shown, a guide rod 250 is vertically fixed on the telescopic support plate 240 , and the guide rod 250 is slidably connected to the upper support plate 230 .

[0095] Specifically, a linear bearing is provided on the upper support plate 230, the lower end of the guide rod 250 is fixed to the telescopic support plate 240 by screws, and the upper end is slidably matched with the linear bearing. A plug is provided on the upper end of the guide rod 250 to prevent the guide rod 250 from coming off the linear bearing.

[0096] In some embodiments of the present application, a first height adjustment mechanism 271 is provided between the upper support plate 230 and the material transfer rack 210, and the first height adjustment mechanism 271 is used to adjust the height of the upper support plate 230, that is, to adjust the distance between the upper support plate 230 and the material receiving base 110, so as to control the height of the fin stack.

[0097] Specifically, the first height adjustment mechanism 271 includes a first adjustment bolt, and the first adjustment bolt tightly connects the upper supporting plate 230 and the material moving rack 210 .

[0098] By rotating the first adjusting bolt, the height of the upper supporting plate 230 can be accurately adjusted, thereby controlling the stacking height of the fin stack. Meanwhile, the height adjustment operation is simple and convenient.

[0099] In some embodiments of the present application, a second height adjustment mechanism 272 is provided at the bottom of the material moving rack 210 . The second height adjustment mechanism 272 is provided between the material moving rack 210 and the material receiving trolley for adjusting the height of the material moving rack 210 .

[0100] The second height adjustment mechanism 272 can assist the first adjustment bolt to adjust the distance between the upper support plate 230 and the material receiving base 110, thereby achieving the purpose of adjusting the fin height.

[0101] Specifically, the second height adjustment mechanism 272 includes a support leg and a second adjustment bolt, and the support leg is fixed and adjusted by the second adjustment bolt. By rotating the second adjustment bolt, the height of the support leg can be adjusted, thereby achieving adjustment of the overall height of the material moving rack 210.

[0102] In some embodiments of the present application, Figure 3 As shown, the end of the material-shifting sleeve 220 that is inserted into the driving member is provided with a first positioning structure 281 that protrudes outward. The first positioning structure 281 is used for positioning the driving member on the automatic unloading device when it is inserted into the material-shifting sleeve 220.

[0103] Specifically, the first positioning structure 281 includes a positioning push rod, and the positioning push rod is fixed on the material shifting sleeve 220 through a mounting hole on the material shifting sleeve 220 .

[0104] In some embodiments of the present application, Figure 4 As shown, a second positioning structure 282 is provided at the bottom of the material moving rack 210. The second positioning structure 282 is used for cooperating with the material receiving trolley for positioning, and plays a positioning role when the material moving rack assembly 200 returns to its original position.

[0105] Specifically, the second positioning structure 282 includes a positioning pin, which is fixed to the bottom of the material moving rack 210 through a mounting hole. A corresponding positioning hole is provided on the material receiving trolley. When the material moving rack assembly 200 is returned to its original position, the positioning pin is inserted into the positioning hole for positioning.

[0106] In some embodiments of the present application, the upper support plate 230 is composed of two upper support plate pieces arranged in parallel, and each upper support plate piece is provided with a first through hole 231 for passing through two rows of material receiving needles 120 on the material receiving rack assembly 100 .

[0107] Similarly, the telescopic support plate 240 is composed of two parallel telescopic support plate single pieces.

[0108] The upper support plate is mounted on the material moving rack 210 through an adjustment plate 260 . A plurality of positioning and mounting holes 261 are arranged at intervals on the adjustment plate 260 . Both ends of the upper support plate are detachably mounted on the positioning and mounting holes 261 .

[0109] The material receiving base 110 is composed of two parallel material receiving base single pieces, and a row of material receiving needles 120 is arranged on each material receiving base single piece.

[0110] The spacing between the material receiving base pieces can be adjusted, and thus the spacing between the two rows of collecting needles can be changed. The spacing between the two upper support plate pieces can be adjusted accordingly through the multiple positioning and mounting holes 261 on the adjustment plate 260 to accommodate fins of different lengths.

[0111] In other embodiments of the present application, the upper support plate 230 is an integral part, and is provided with two parallel first through holes 231 for passing through two rows of receiving needles 120 on the receiving frame assembly 100. When the upper support plate 230 is an integral part, installation and adjustment are relatively simple.

[0112] The telescopic support plate 240 may also be an integral piece or consist of two telescopic support plates.

[0113] In some embodiments of the present application, Figure 7 As shown, the first through hole 231 is an elongated hole arranged along the length direction of the upper support plate 230, which is convenient for processing and manufacturing, and also convenient for the connecting needle 120 to pass through.

[0114] like Fig. 9 As shown, the second through hole 232 is located on one side of the first through hole 231, effectively avoiding the material receiving needle 120, and facilitating the insertion of the auxiliary material taking needle 400. The second through hole 232 is connected with the first through hole 231 to form a special-shaped hole structure, which is convenient for processing and manufacturing, and is also convenient for the insertion of the auxiliary material taking needle 400.

[0115] In some embodiments of the present application, a guide column 130 is further provided on the material receiving base 110 .

[0116] The guide posts 130 are located at both ends of each row of the connecting needles 120 , and through holes corresponding to the guide posts 130 are provided on the upper support plate 230 and the telescopic support plate 240 so that the guide posts 130 can pass through.

[0117] The guide column 130 plays a guiding and positioning role when the material moving rack assembly 200 moves up and down, ensuring the stable operation of the material moving rack assembly 200 in the vertical direction.
