Description

Technical Field

[0001] This utility model specifically relates to the field of hanging rack loading and unloading technology, and more specifically to a loading and unloading mechanism for cleaning hanging racks. Background Technology

[0002] After electroplating, the hangers need to be effectively cleaned of any residual medium on their surface to prevent the dirt from affecting subsequent use. When cleaning the hangers, the hangers are placed into the cleaning tank through a conveyor device. Different cleaning media are used to effectively clean the dirt remaining on the surface of the hangers, thereby ensuring the quality of the cleaning.

[0003] Currently, traditional hanging racks are typically cleaned manually, which can lead to injuries from residual dirt on the rack surface during loading. The unloading process after cleaning is slow, and repetitive operations can cause worker fatigue. Furthermore, the limited quantity that can be processed within a given time further impacts efficiency. While automated loading and unloading devices exist, they may experience longer waiting times during loading and unloading, thus hindering the continuous transport capabilities of the conveyor system.

[0004] A search revealed that Chinese Patent Publication No. CN201922090875.6 discloses an automatic loading and unloading structure for an LED lamp heat sink hanger; it includes a hanger body, a central rod on the hanger body, a hook on the top of the central rod, several layers of hooks around the outer periphery of the central rod, the central rod and the hooks being rotatably connected, a first gear on the central rod, and a lifting platform, a lifting ring on the lifting platform, a first drive motor on one side of the lifting platform, a second gear on the output shaft of the first drive motor, a loading conveyor belt and a unloading conveyor belt on the side of the lifting platform, a discharge guide rod on the loading conveyor belt, a discharge channel formed between the discharge guide rod and the side support of the loading conveyor belt, and pneumatic gripper drive structures for loading and unloading on both the loading and unloading conveyor belts;

[0005] Although the device in the aforementioned patent can automatically load and unload the hangers, in actual production, it may be limited by factors such as the speed of the loading and unloading conveyor belts and the gripping frequency of the pneumatic grippers, resulting in the overall loading and unloading efficiency still not being able to meet the needs of some large-scale, high-capacity production. Utility Model Content

[0006] The purpose of this invention is to provide a loading and unloading mechanism for cleaning hangers. In this device, the hangers to be cleaned are placed on a mobile cart and then transported to one end of the frame. Through the cooperation between the connecting belt and the ear bracket, the overall lifting effect of the circulating component is achieved. During the lifting process, the hanger at one end cooperates with the hanger to be loaded, and the hanger at the other end cooperates with the cleaned hanger, thereby achieving the effect of synchronous loading and unloading. In loading and unloading, the loading and unloading component on the mobile cart moves the hanger to the designated position, thereby effectively cooperating with the hangers on the hanger in the circulating transmission; thus improving the working efficiency and solving the problems of the aforementioned background technology.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0009] The top of the cleaning tank is equipped with a circulation component; the circulation component includes a lifting frame; a chain is installed inside the lifting frame through a sprocket; multiple hangers are fixedly installed on the chain; two sets of ear brackets are integrally arranged on both sides of the lifting frame; the ear brackets are fixedly connected to the connecting belt; the hangers are L-shaped and have V-shaped grooves.

[0010] As a further technical solution of this utility model, both ends of the lifting assembly are provided with a moving vehicle and a loading / unloading assembly; wherein, the loading / unloading assembly is fixedly installed on one side of the moving vehicle; by setting the moving vehicle and the loading / unloading assembly at both ends of the frame respectively, the loading and unloading of the loading rack and the cleaned rack can be effectively realized, thereby effectively improving work efficiency.

[0011] As a further technical solution of this utility model, the loading and unloading assembly includes a support frame; the support frame is welded and fixed to the mobile vehicle; a lead screw and a guide rod are installed between the crossbeams of the support frame; wherein; the bottom of the lead screw is fixedly installed to the second drive motor; a movable block is also movably installed on the lead screw and the guide rod; two lifting plates are provided on the side of the movable block near the mobile vehicle;

[0012] As a further technical solution of this utility model, the mobile vehicle is equipped with a hanger; the top two ends of the hanger are provided with V-shaped plates that facilitate cooperation with the hanger; the V-shaped plates are effectively engaged with the V-shaped grooves opened on the hanger, thereby ensuring the stability of the hanger during cleaning.

[0013] As a further technical solution of this utility model, one end of the rotating shaft is fixedly installed with the first drive motor; the first drive motor is fixedly installed at one end of the frame; the rotating shaft drives the two connecting belts to extend or retract synchronously through the first drive motor, thereby ensuring the stability of the lifting frame during the up and down movement; thereby ensuring the efficiency and quality of cleaning the hanging fixtures.

[0014] As a further technical solution of this utility model, the sprockets installed inside both ends of the lifting frame are coaxially arranged through connecting rods; wherein one end of the connecting rod is fixedly installed with the reducer;

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In this invention, the hanger to be cleaned is placed on a mobile cart during use. The mobile cart is then moved to the direction in which the chain inside the lifting frame drives the hanger to move. The loading and unloading assembly then moves the hanger to a designated height, thereby effectively ensuring automatic coordination between the hanger and the hanger and reducing manual intervention.

[0017] In this invention, during the loading of the hanger, the first drive motor drives the connecting belt to rotate, which in turn drives the lifting frame downward through the ear bracket. As the lifting frame moves downward, the loaded hanger is moved into the cleaning box. After the hanger is cleaned in one of the cleaning boxes, the lifting frame moves upward. At this time, the hanger on the feeding direction of the lifting frame is effectively engaged with the hanger on the moving vehicle. Then, the transmission between the sprocket and the chain is achieved through the reducer, so that the loaded hanger is moved forward. At the same time, the previous hangers are moved forward in sequence into the subsequent cleaning boxes, thereby achieving different degrees of cleaning of the hangers.

[0018] In this invention, during the downward movement of the lifting frame, the lifting plate in the loading and unloading assembly on the moving vehicle at the other end of the frame drives the lead screw to rotate via the second drive motor, thereby moving the moving block upward and moving the lifting plate to a certain height. This ensures that when the lifting frame moves the hanger downward, the lifting plate and the cleaned hanger work together effectively, thus achieving the effect of automatically unloading the cleaned and bent hanger.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-6 In this embodiment of the utility model, a loading and unloading mechanism for cleaning hangers includes a lifting assembly 2; the lifting assembly 2 includes a frame 20; multiple cleaning boxes 1 are fixedly installed inside the frame 20; a rotating shaft 22 is installed on the top crossbeam of the frame 20 through a bearing seat; two connecting belts 23 are installed on the rotating shaft 22; the connecting belts 23 are Z-shaped; and transition wheels 24 are movably installed on the side of the two crossbeams of the frame 20 away from the rotating shaft 22.

[0028] The top of the cleaning tank 1 is provided with a circulation component 6; the circulation component 6 includes a lifting frame 60; a chain 61 is installed inside the lifting frame 60 through a sprocket; multiple hangers 62 are fixedly installed on the chain 61; two sets of ear brackets 63 are integrally provided on both sides of the lifting frame 60; the ear brackets 63 are fixedly connected to the connecting belt 23; the hangers 62 are L-shaped and have V-shaped grooves.

[0029] The lifting assembly 2 is provided with a mobile vehicle 3 and a loading / unloading assembly 5 at both ends; wherein the loading / unloading assembly 5 is fixedly installed on one side of the mobile vehicle 3.

[0030] By adopting the above technical solution, during use, the hanger 4 that needs to be cleaned is placed on the mobile cart 3, and the mobile cart 3 is moved to the direction in which the chain 61 inside the lifting frame 60 drives the hanger 62 to move. Then, the loading and unloading assembly 5 moves the hanger 4 to the designated height, thereby effectively ensuring automatic coordination between the hanger 4 and the hanger 62 and reducing manual intervention.

[0031] In this embodiment, the loading and unloading assembly 5 includes a support frame 50; the support frame 50 is welded and fixed to the mobile vehicle 3; a lead screw 55 and a guide rod 52 are fitted between the crossbeams of the support frame 50; wherein, the bottom of the lead screw 55 is fixedly installed with the second drive motor 51; a moving block 54 is also movably installed on the lead screw 55 and the guide rod 52; two lifting plates 53 are provided on the side of the moving block 54 near the mobile vehicle 3;

[0032] In this embodiment, a hanger 4 is placed on the mobile vehicle 3; the top two ends of the hanger 4 are provided with V-shaped plates to facilitate cooperation with the hanger 62;

[0033] By adopting the above technical solution, when the hanger 4 is loaded, the first drive motor 21 drives the shaft 22 to rotate the connecting belt 23, and the connecting belt 23 drives the lifting frame 60 to move downward through the ear bracket 63. When the lifting frame 60 moves downward, the loaded hanger 4 is moved into the cleaning box 1. After the hanger 4 is cleaned in one of the cleaning boxes 1, the lifting frame 60 moves upward. At this time, the hanger 62 in the feeding direction of the lifting frame 60 is effectively engaged with the hanger 4 on the moving vehicle 3. Then, the transmission between the sprocket and the chain is realized through the reducer 64, so that the loaded hanger 4 is moved forward. At the same time, the previous hangers 4 are moved forward in sequence into the subsequent cleaning boxes 1, thereby realizing the cleaning of the hangers 4 to different degrees.

[0034] Furthermore, one end of the rotating shaft 22 is fixedly installed with the first drive motor 21; the first drive motor 21 is fixedly installed at one end of the frame 20.

[0035] In this embodiment, the sprockets installed inside both ends of the lifting frame 60 are coaxially arranged through connecting rods; wherein one end of the connecting rod is fixedly installed with the reducer 64;

[0036] By adopting the above technical solution, during the downward movement of the lifting frame 60, the lifting plate 53 in the loading and unloading assembly 5 on the moving vehicle 3 at the other end of the frame 20 drives the lead screw 55 to rotate through the second drive motor 51, so that the lead screw 55 moves the moving block 54 upward, thereby moving the lifting plate 53 to a certain height, thus ensuring that when the lifting frame 60 drives the hanger 62 to move downward, the lifting plate 53 and the cleaned hanger 4 can cooperate effectively, thereby achieving the effect of automatically unloading the cleaned bent hanger 4;

[0037] The working principle of this utility model is as follows: During use, the hanger 4 that needs to be cleaned is placed on the mobile cart 3.

Then, the loading and unloading assembly 5 moves the hanger 4 to the specified height, thereby effectively ensuring automatic cooperation between the hanger 4 and the hanger 62 and reducing manual intervention.

[0038] When the hanger 4 is loaded, the first drive motor 21 drives the shaft 22 to rotate the connecting belt 23, which in turn drives the lifting frame 60 to move downward through the ear bracket 63. When the lifting frame 60 moves downward, the loaded hanger 4 is moved into the cleaning box 1. After the hanger 4 is cleaned in one of the cleaning boxes 1, the lifting frame 60 moves upward. At this time, the hanger 62 in the feeding direction of the lifting frame 60 is effectively engaged with the hanger 4 on the moving vehicle 3. Then, the transmission between the sprocket and the chain is realized through the reducer 64, so that the loaded hanger 4 is moved forward. At the same time, the previous hangers 4 are moved forward in sequence into the subsequent cleaning boxes 1, thereby realizing the cleaning of the hangers 4 to different degrees.

[0039] As the lifting frame 60 moves downward, the lifting plate 53 in the loading and unloading assembly 5 on the moving vehicle 3 at the other end of the frame 20 drives the lead screw 55 to rotate through the second drive motor 51, so that the lead screw 55 moves the moving block 54 upward, thereby moving the lifting plate 53 to a certain height. This ensures that when the lifting frame 60 drives the hanger 62 to move downward, the lifting plate 53 and the cleaned hanger 4 can cooperate effectively, thereby achieving the effect of automatically unloading the cleaned bent hanger 4.
