Description

Technical Field

[0001] This utility model relates to the field of industrial spraying equipment technology, specifically to a controllable rotating hanger. Background Technology

[0002] In industrial spraying operations, workpieces are usually sent into the spray booth via a suspended conveyor chain to complete surface treatment. The workpieces are generally sent into the spray booth by hanging fixtures. This ensures that the workpieces are suspended and exposed to all surfaces to be sprayed, while avoiding contact between the workpieces and the conveyor belt, which could cause coating defects. Furthermore, the excess paint can be allowed to drip off naturally by gravity.

[0003] Existing hangers mostly employ fixed structures or simple swing designs, failing to achieve precise angle rotation. They rely solely on workpiece oscillation to achieve limited coverage, resulting in blind spots in the spraying process and high paint waste. Furthermore, paint atomization particles within the spray booth easily seep along the hooks into the conveyor mechanism, causing jamming of transmission components after solidification. Additionally, paint adheres to the hook surface, but existing hooks are mostly bolted, requiring specialized tools for disassembly and reassembly for cleaning, leading to lengthy maintenance times and high worker workload. Therefore, we need a hanger with controllable rotation. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are: this controllable rotation hanging device...

[0013] (1) When the hook below the conveyor belt body enters the spray booth, the isolation plate can prevent the paint below from entering the upper conveyor belt body structure to prevent mechanical failure. Since the first and second connecting rods of the Y-shaped connecting frame are hinged and have high mobility, they can enter the curved conveyor belt body. When the hook enters the spray booth, it moves along the track. There are two baffles on the outside of the conveyor belt body. After the cross-wing frame reaches the corresponding position, the tip of the cross-wing frame will contact the baffle. The cross-wing frame is resisted and the rotating block generates self-spinning, causing the cross-wing frame to rotate. This allows all the structures below the cross-wing frame to rotate 90 degrees. The two baffles can make the cross-wing frame rotate twice, for a total of 180 degrees. This not only makes the object below the hook more thoroughly sprayed, but also saves paint.

[0014] (2) After the device has been used for a long time, the user can pull the lever to move the front end of the locking block out of the slot and remove the hook. The hook can be installed and removed by using the locking block and the slot. No tools are required for installation and removal, which not only reduces the labor intensity of workers, but also makes it easier for users to clean and maintain the paint on the surface of the hook, prevent objects from slipping off the hook during movement, and ensure stable spraying quality.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] This utility model embodiment provides a controllable rotation hanging device, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the system includes a conveyor belt body 1, with multiple Y-shaped connecting frames 2 installed inside the conveyor belt body 1. Each Y-shaped connecting frame 2 has a fixed rod 3 hinged to its lower end. Each fixed rod 3 has a rotating component 4 installed at its lower end. Each rotating component 4 has an isolation disc 5 fixedly installed at its lower end. Each isolation disc 5 has a snap-fit ​​component 6 installed at its upper end. Each snap-fit ​​component 6 has a hook 7 installed inside it. The rotating component 4 includes a rotating block 401 and a stop bar 402. The rotating block 401 is rotatably connected to the lower end of the fixed rod 3. There are two stop bars 402, which are fixedly connected to the outer side wall of the conveyor belt body 1. A cross-wing frame 403 is fixedly connected to the side wall of the rotating block 401. Two support rods 404 are symmetrically fixedly connected to the lower end of the cross-wing frame 403. The isolation disc 5 is fixedly connected to the lower end of the two support rods 404.

[0022] First, the conveyor belt body 1 is fixedly installed inside the spray booth. Then, the object to be sprayed is installed below the hook 7. The conveyor belt body 1 then transports the hook 7 into the spray booth for processing. Subsequently, the isolation disc 5 can prevent the paint from entering the upper conveyor belt body 1 structure to prevent mechanical failure. Furthermore, because the first and second connecting rods of the Y-shaped connecting frame 2 are hinged, they have high mobility and can enter the curved conveyor belt body 1. When the hook 7 enters the spray booth, the object moves along the track of the conveyor belt body 1. 1. There are two stop bars 402 on the outside. After the cross-shaped frame 403 is in the corresponding position, the tip of the cross-shaped frame 403 will contact the stop bar 402. The cross-shaped frame 403 is resisted, causing the rotating block 401 to spin, thus rotating the cross-shaped frame 403. This allows all the structures below the cross-shaped frame 403 to rotate 90 degrees. The two stop bars 402 can make the cross-shaped frame 403 rotate twice, for a total of 180 degrees. This not only allows for more comprehensive and thorough spraying of the objects below the hook 7, but also saves paint.

[0023] It is worth noting that the conveyor belt body 1 is existing technology. The conveyor belt body 1 mainly consists of a ring track composed of linear guide rails and arc guide rails, a transmission device, and a positioning system. The working principle is that the drive device drives the transmission chain or synchronous belt to rotate, and the friction force makes the slide or slider slide continuously along the track. The arc-shaped conveying of materials is achieved by relying on the curved guidance of the track. The conveyor belt body 1 can drive the Y-shaped connecting frame 2 to move. The upper ends of the first and second connecting rods of the Y-shaped connecting frame 2 are fixed on the slide of the conveyor belt body 1. The force of the drive device is directly transmitted to the connecting frame through the transmission chain or belt to achieve synchronous and stable arc-shaped movement. It will not be elaborated here. The position of the stop bar 402 should be symmetrically set at the two ends of the arc guide rail of the conveyor belt body 1 to ensure that the axis of the stop bar 402 is perpendicular to avoid rotational deviation. The contact point between the stop bar 402 and the cross-wing frame 403 should be located on the outer edge of the side wall of the cross-wing frame 403, close to the tip, to maximize the rotational torque and reduce stress concentration. Through two contacts, each rotation of 90 degrees, the object can stably complete a 180-degree rotation.

[0024] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 4 As shown, the snap-fit ​​assembly 6 includes a fixing block 601, which is fixedly connected to the center of the upper end of the insulating disk 5. The lower end of the fixing block 601 has an insertion port 602. Two sliding cavities 603 are symmetrically formed inside the fixing block 601, located on either side of the insertion port 602. A set of springs 604 is fixedly connected to the inner wall of each of the two sliding cavities 603. A locking block 605 is fixedly connected to the front end of each of the two sets of springs 604. The two locking blocks 605 are slidably connected within the two sliding cavities 603, and the front ends of the two locking blocks 605 are wedge-shaped. The front ends of the two locking blocks 605 respectively penetrate the inner walls of the two sliding cavities 603, and the front ends of the two locking blocks 605 are slidably set in the insertion port 602. An insertion block 606 is placed in the insertion port 602, and the insertion block 606 penetrates the center of the isolation plate 5. The hook 7 is fixedly connected to the lower end of the insertion block 606. The insertion block 606 has a slot 607 on both sides, and the front ends of the two locking blocks 605 respectively engage with the two slots 607. Pull rods 608 penetrate both sides of the fixing block 601, and one end of the two pull rods 608 is fixedly connected to one side of the two locking blocks 605 respectively.

[0025] After prolonged use, the user can pull the pull block 8 to retract the spring 604, causing the front end of the locking block 605 to move out of the slot 607, allowing the insert block 606 to be removed from the socket 602. At this point, the hook 7 can be removed. When the hook 7 needs to be installed, the insert block 606 is inserted into the socket 602. The wedge-shaped front end of the locking block 605 is pushed and retracts, causing the locking block 605 to retract into the sliding cavity 603. When the side wall of the insert block 606... When the slot 607 is aligned with the front end of the block 605, the spring 604 contracts, allowing the front end of the block 605 to automatically move into the slot 607, thus securing the insert block 606. The hook 7 is installed and removed using the block 605 in conjunction with the slot 607, requiring no tools. This not only reduces the workload for workers but also facilitates cleaning and maintenance of accumulated paint on the hook 7 surface, preventing objects from slipping off the hook 7 during movement and ensuring stable coating quality.

[0026] like Figure 4 As shown, each of the two pull rods 608 has a fixed actuating block 8 at the end away from the insertion port 602, and the side walls of the two actuating blocks 8 are provided with anti-slip texture. The actuating blocks 8 make it easy for the user to pull the pull rod 608, thereby causing the locking block 605 to retract into the sliding cavity 603, improving the portability of the device.

[0027] like Figure 2 and Figure 4 As shown, a stop block 9 is fixedly connected to the upper part of the outer wall of the hook 7, and the upper end of the stop block 9 is fixedly connected to the lower end of the insert block 606. The stop block 9 can block and protect the insertion port of the insert block 606 into the isolation plate 5, preventing paint from entering the insertion port.

[0028] like Figure 1 and Figure 2 As shown, multiple mounting brackets 10 are fixedly installed on the upper end of the conveyor belt body 1. The mounting brackets 10 facilitate users in installing the conveyor belt body 1 in a designated position, improving the portability of the device.

[0029] like Figure 3 and Figure 4 As shown, the Y-shaped connecting frame 2 consists of a first connecting rod and a second connecting rod that are hinged to each other. The first connecting rod and the second connecting rod of the Y-shaped connecting frame 2 are connected by a pin-type hinge structure. This structure allows the support to deflect freely in the vertical plane. When the top of the Y-shaped connecting frame 2 moves along the conveyor belt body 1, the hinge point can automatically adjust the angle to compensate for changes in the curvature of the path. At the same time, the pin provides axial locking while allowing slight rotation of the joint through the fitting clearance, ensuring the integrity of the structure and its adaptability to movement, thereby meeting the dynamic requirements of the Y-shaped connecting frame 2 as it moves along the conveyor belt body 1.

[0030] like Figure 3 and Figure 4As shown, the side wall of hook 7 is equipped with an anti-slip pad layer, which is made of rubber. The anti-slip pad layer enhances stability and effectively prevents objects from sliding on hook 7 during spraying operations.

[0031] Working principle: First, the conveyor belt body 1 is fixedly installed inside the spray booth. Then, the object to be sprayed is installed below the hook 7. The conveyor belt body 1 then transports the hook 7 into the spray booth for processing. Subsequently, the isolation disc 5 can prevent the paint from entering the upper conveyor belt body 1 structure, preventing mechanical failure. Furthermore, because the first and second connecting rods of the Y-shaped connecting frame 2 are hinged, they have high mobility and can enter the curved conveyor belt body 1. When the hook 7 enters the spray booth, the object moves along the conveyor belt body... 1. Track movement: The outer side of the conveyor belt body 1 has two stop bars 402. After the cross-wing frame 403 reaches the corresponding position, the tip of the cross-wing frame 403 will contact the stop bar 402. The resistance of the cross-wing frame 403 causes the rotating block 401 to spin, making the cross-wing frame 403 rotate. This allows all structures below the cross-wing frame 403 to rotate 90 degrees. The two stop bars 402 can make the cross-wing frame 403 rotate twice, a total of 180 degrees. This allows for spraying not only the objects below the hook 7. More comprehensive and thorough, while saving paint. After prolonged use, the user can pull the pull block 8 to retract the spring 604, causing the front end of the locking block 605 to move out of the slot 607, allowing the insert block 606 to be removed from the socket 602. The hook 7 can then be removed. When the hook 7 needs to be installed, insert the insert block 606 into the socket 602. The wedge-shaped front end of the locking block 605 is pushed and retracts, causing the locking block 605 to retract into the sliding cavity 603. When the slot 607 on the side wall of the insert block 606 is aligned with the front end of the slot block 605, the spring 604 contracts, allowing the front end of the slot block 605 to automatically move into the slot 607, thus fixing the insert block 606. The hook 7 is installed and removed using the slot 607 in conjunction with the slot block 605. Installation and removal can be done without tools, which not only reduces the labor intensity of workers, but also makes it easier for users to clean and maintain the paint accumulation on the surface of the hook 7, preventing objects from slipping off the hook 7 during movement and ensuring stable spraying quality.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
