Description

Technical Field

[0001] This utility model relates to a powder coating hanger device, belonging to the field of automated spraying production lines, and particularly to a liftable powder coating hanger device. Background Technology

[0002] Powder spraying is a process in which particulate solid polymer powder is applied to the surface of a workpiece using compressed air or electrostatic adsorption, excess powder is blown off the workpiece surface (i.e., powder blowing), and then the powder is melted by high-temperature baking to form a strong coating. Powder spraying is one of the core processes of surface coating technology and is widely used in the anti-corrosion, decorative and functional coating treatment of metal products.

[0003] Chinese patent application number 202222211987.4, filed on August 22, 2022, discloses a powder spraying fixture for cylindrical products, relating to the field of fixture technology. This powder spraying fixture for cylindrical products includes an installation rod with a groove at its lower end. A hanging rod is slidably connected to the inner wall of the groove. Multiple horizontal plates are fixedly connected to the side wall of the hanging rod, and multiple fixing rods are symmetrically fixedly connected to the upper ends of the horizontal plates. A hook is fixedly connected to the upper end of the installation rod. An anti-drop mechanism is installed on the fixing rod, comprising multiple fixing brackets symmetrically fixedly connected to the side wall of the fixing rod. Each fixing bracket has a groove. The anti-drop mechanism also includes a sliding plug slidably connected to the inner wall of the groove, and a fixing head is fixedly connected to the side wall of the sliding plug. Although this design can complete the powder spraying process onto the product surface, it still has the following drawbacks:

[0005] The information disclosed in this background section is intended only to enhance understanding of the overall background of this application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to overcome the defects and problems of low processing efficiency in the existing technology and to provide a liftable powder spraying fixture device with high processing efficiency.

[0007] To achieve the above objectives, the technical solution of this utility model is:

[0008] A liftable powder spraying device, the device comprising a support device, a hanging rod, and a frame;

[0009] The hanging rod is connected to the frame;

[0010] The supporting device includes a base plate, a support rod, and a top plate for supporting the workpiece. One end of the support rod is connected to the top plate, and the other end of the support rod passes through the base plate and is connected to the tensioning member. The support rod is slidably connected to the base plate and can move up and down along the base plate. The base plate is mounted on the frame.

[0011] The support rod is fitted with a spring at the part located above the base plate.

[0012] The top of the support rod is fitted with a sleeve for accommodating the spring, and the top of the sleeve is connected to the bottom of the top plate.

[0013] The support rod is fitted with a linear bearing, and the outer surface of the linear bearing is connected to the inner surface of the hole in the base plate.

[0014] The base plate is provided with a guide rod hole, and a guide rod is inserted into the guide rod hole. The guide rod moves up and down along the guide rod hole. The top of the guide rod is connected to the bottom of the top plate.

[0015] The number of guide rod holes is two, with the two guide rod holes diagonally distributed along the bottom plate and the two guide rods diagonally distributed along the top plate.

[0016] The number of the supporting devices is two, and the two supporting devices are symmetrically distributed along the hanging rod.

[0017] The bottom of the hanging rod is inserted into the middle of the frame, and the top of the hanging rod is a hook.

[0018] The tensioning member includes a roller shaft, the top of which is connected to the bottom of a support rod, and the bottom of which is connected to a left roller and a right roller. The left roller and the right roller are slidably connected to the undulating platform.

[0019] The top plate is located inside the workpiece, and the edge of the top plate matches the inner edge of the workpiece.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. In this utility model, a liftable powder spraying fixture device includes a supporting device, a hanging rod, and a frame. The hanging rod is connected to the frame. The supporting device includes a base plate, a support rod, and a top plate for supporting the workpiece. One end of the support rod is connected to the top plate, and the other end passes through the base plate and is connected to a tensioning member. The support rod is slidably connected to the base plate. The base plate is installed on the frame. In application, the workpiece is first placed on the top plate, and then the tensioning member is pulled down to move the top plate and the workpiece downward until the bottom of the workpiece is sealed by the base plate. Then, the workpiece is powder sprayed. Then, the tensioning member is pushed upward to move the top plate and the workpiece upward until the bottom of the workpiece leaves the base plate, i.e., the entire workpiece is exposed. Then, the workpiece is thoroughly powdered. The advantages of this utility model also include:

[0022] Firstly, it can seal the bottom of the workpiece and expose the bottom of the workpiece so that the state of the workpiece meets the process requirements of powder spraying and powder blowing, thus enabling the workpiece to be powder sprayed and powder blown.

[0023] Secondly, there is no need to rely on manual transfer of workpieces. Simply pull down the stretching part to blow powder onto the workpiece, so the processing efficiency is high and the operation is convenient.

[0024] Therefore, this utility model has high processing efficiency and is easy to operate.

[0025] 2. In this utility model, a liftable powder spraying device is provided, in which a spring is fitted onto the portion of the support rod above the base plate. A sleeve is provided at the top of the support rod to accommodate the spring. In application, when the top plate moves downwards, it compresses the spring. At this time, the sleeve wraps around the spring to reduce its compressed volume. When the top plate moves upwards, the compressed spring releases its elastic force to assist the top plate in moving upwards. Therefore, this utility model provides good assistance for the movement of the top plate.

[0026] 3. In this utility model of a liftable powder spraying fixture, a linear bearing is fitted around the support rod. The outer surface of the linear bearing is connected to the base plate. During application, the linear bearing reduces the friction when the support rod moves up and down, ensuring smooth movement of the support rod and thus smooth movement of the workpiece. This results in higher efficiency in workpiece movement and saves processing time. Therefore, this utility model can save processing time.

[0027] 4. In this utility model, a liftable powder spraying fixture device has two diagonally distributed guide rod holes on the base plate. Guide rods are inserted into the guide rod holes, with the top of the guide rods connected to the top plate and the middle of the guide rods slidably connected to the base plate. In application, the two diagonally distributed guide rods not only provide balanced support for the top plate but also prevent the top plate from rotating, thus providing stable support for the workpiece. Therefore, this utility model provides good support for the workpiece.

[0028] 5. In this utility model, a liftable powder spraying fixture device has two supporting devices symmetrically distributed along the hanging rod. During application, two workpieces can be powder sprayed or blown simultaneously, thus further improving processing efficiency. Therefore, this utility model can process two workpieces simultaneously.

[0029] 6. In this utility model of a height-adjustable powder spraying device, the bottom of the hanging rod is connected to the frame, and the top of the hanging rod is a hook. In application, the hook can cooperate with a chain, and the chain drives the hook to move, thereby moving the device, so that the device can circulate between the powder spraying area and the powder blowing area. Therefore, the circulating movement effect of this utility model is better.

[0030] 7. In this utility model, a liftable powder spraying fixture device includes a tensioning component comprising a roller shaft and rollers. The rollers engage with an undulating platform. During application, the rollers, which gradually descend along the platform, move the support rod, top plate, and workpiece downwards until the bottom plate seals the bottom of the workpiece. Conversely, the rollers, which gradually rise along the platform, move the support rod, top plate, and workpiece upwards until the bottom plate moves away from the bottom of the workpiece, exposing the bottom of the workpiece. Therefore, the sealing and exposure of the workpiece bottom can be achieved without manually pulling the tensioning component, resulting in lower labor costs. Thus, this utility model has low labor costs.

[0031] 8. In this utility model's liftable powder spraying fixture, the top plate is located inside the workpiece. During application, the top plate supports the workpiece from within, achieving a sealing and exposure effect between the workpiece and the bottom plate. The edge of the top plate matches the inner edge of the workpiece, meaning the inner surface of the workpiece is in contact with the top surface of the top plate. The inner surface of the workpiece will not be higher than the top surface of the top plate, thus achieving a stable support and sealing effect. Therefore, the sealing effect of this utility model is stable. Attached Figure Description

[0042] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] Please see Figure 1 — Figure 9 A liftable powder coating hanger device is disclosed, comprising a support device 1, a hanging rod 21, and a frame 24; the hanging rod 21 is connected to the frame 24; the support device 1 includes a base plate 25, a support rod 22, and a top plate 23 for supporting a workpiece 4; one end of the support rod 22 is connected to the top plate 23, and the other end of the support rod 22 passes through the base plate 25 and is connected to a tension member 27; the support rod 22 is slidably connected to the base plate 25 and can move up and down along the base plate 25; the base plate 25 is mounted on the frame 24.

[0044] In application, the workpiece 4 is a die-cast lamp required for automated vegetable cultivation. Workpiece 4 mainly consists of a lower housing 41 and an upper cover plate 42. First, workpiece 4 is placed on the top plate 23. Then, the tensioning member 27 moves downwards, which in turn moves the support rod 22 downwards. The support rod 22 then moves the top plate 23 downwards, and the top plate 23 moves the workpiece 4 downwards until the bottom of workpiece 4 is sealed by the top of the top plate 23. Then, workpiece 4 is powder-coated. At this point, because the bottom of workpiece 4 is sealed by the top of the top plate 23, the powder... The powder will not enter the interior of workpiece 4, so this device can meet the process requirements of powder spraying. After the powder spraying is completed, the tensioning member 27 is moved upward, and then the tensioning member 27 drives the support rod 22 to move upward, and then the support rod 22 drives the top plate 23 to move upward, and then the top plate 23 drives the workpiece 4 to move upward until the bottom of the workpiece 4 is far away from the top of the bottom plate 25. At this time, the bottom of the workpiece 4 is exposed, and then the workpiece 4 is blown with powder. At this time, because the bottom of the workpiece 4 is exposed, the workpiece 4 can be fully blown with powder, so this device can meet the process requirements of powder blowing.

[0045] In another embodiment of this application, please refer to Figure 2 — Figure 9 A spring 6 is fitted onto the support rod 22 located above the base plate 25.

[0046] Furthermore, the top of the support rod 22 is fitted with a sleeve 61 for accommodating the spring 6, and the top of the sleeve 61 is connected to the bottom of the top plate 23.

[0047] In application, when the tension member 27 moves downward, the top plate 23 moves downward, so the top plate 23 compresses the spring 6. At this time, the spring 6 is located inside the sleeve 61 to save the compression volume of the spring 6. When the tension member 27 moves upward, the top plate 23 moves upward, so the compressed spring 6 gradually releases its elastic force to assist the top plate 23 in moving upward.

[0048] In another embodiment of this application, please refer to Figure 3 , Figure 4 , Figure 6 The support rod 22 is fitted with a linear bearing 254, and the outer surface of the linear bearing 254 is connected to the inner surface of the bottom plate hole 253 on the bottom plate 25.

[0049] Furthermore, the fixing screw 5 passes through the base plate 25 and is inserted into the top of the linear bearing 254 to fix the linear bearing 254 to the base plate 25.

[0050] In application, the linear bearing 254 can reduce the friction when the support rod 22 moves up and down, so that the support rod 22 moves smoothly and can also extend the service life of the support rod 22; the linear bearing 254 is fixed to the base plate 25 by the fixing screw 5, so that the connection between the linear bearing 254 and the base plate 25 is stable.

[0051] In another embodiment of this application, please refer to Figure 8 , Figure 9 The base plate 25 is provided with a guide rod hole 251, and a guide rod 252 is inserted into the guide rod hole 251. The guide rod 252 moves up and down along the guide rod hole 251. The top of the guide rod 252 is connected to the bottom of the top plate 23.

[0052] Furthermore, there are two guide rod holes 251, which are diagonally distributed along the bottom plate 25, and two guide rods 252 are diagonally distributed along the top plate 23.

[0053] Furthermore, a linear bearing 254 is fitted around the outside of the guide rod 252, and the outer surface of the linear bearing 254 is connected to the inner surface of the guide rod hole 251.

[0054] In application, when the top plate 23 moves upward, it drives the guide rod 252 to move upward; when the top plate 23 moves downward, it drives the guide rod 252 to move downward. The guide rod 252 provides support for the top plate 23 to stabilize the movement of the top plate 23. The two guide rods 252 are diagonally distributed along the top plate 23 to prevent the top plate 23 from rotating during the up and down movement, so that the top plate 23 provides stable support for the workpiece 4.

[0055] In another embodiment of this application, please refer to Figure 2 , Figure 5 The number of the bearing devices 1 is two, and the two bearing devices 1 are symmetrically distributed along the hanging rod 21.

[0056] When in use, workpieces 4 can be placed on two supporting devices 1 at the same time to achieve the effect of spraying and blowing powder on two workpieces 4 simultaneously; and the two supporting devices 1 are symmetrically distributed along the hanging rod 21, so the weight is relatively balanced and will not cause the device to tip over.

[0057] In another embodiment of this application, please refer to Figure 1 , Figure 5 The bottom of the hanging rod 21 is inserted into the middle of the frame 24, and the top of the hanging rod 21 is a hook 211.

[0058] Furthermore, the middle part of the frame 24 is a middle plate 26, and the bottom of the hanging rod 21 is connected to the middle plate 26.

[0059] In application, the hook 211 can be connected to a chain or other moving parts to drive the hook 211 to move, and then the hook 211 drives the frame 24 and the supporting device 1 to move, so as to achieve the effect of the device moving cyclically in the powder spraying area and the powder blowing area.

[0060] In another embodiment of this application, please refer to Figure 1 , Figure 3 The tensioning member 27 includes a roller shaft 271, the top of which is connected to the bottom of the support rod 22, and the bottom of which is connected to a left roller 272 and a right roller 273. The left roller 272 and the right roller 273 are slidably connected to the undulating platform 7.

[0061] Furthermore, the bottom of the roller shaft 271 is connected to the top of the roller block 274, one side of the roller block 274 is connected to one side of the left roller 272, and the other side of the roller block 274 is connected to one side of the right roller 273.

[0062] Furthermore, the tensioning member 27 can be a hook-shaped component or other components with limiting functions.

[0063] Furthermore, the top of the roller shaft 271 is connected to the bottom of the bearing 3, and the top of the bearing 3 is connected to the bottom of the support rod 22.

[0064] In application, when the left roller 272 and right roller 273 rise along the platform 7, they drive the roller shaft 271 to rise, which in turn drives the support rod 22 to rise. The support rod 22 then drives the top plate 23 and workpiece 4 to rise. When the left roller 272 and right roller 273 descend along the platform 7, they drive the roller shaft 271 to descend, which in turn drives the support rod 22 to descend. The support rod 22 then drives the top plate 23 and workpiece 4 to descend, thus achieving automatic lifting. The highest and lowest heights of the platform 7 are all on a horizontal line. The heights are connected by a slope; when the tension member 27 is a hook-shaped component, it can cooperate with the undulating rod-shaped component, and the hook component can slide along the horizontal direction of the rod-shaped component to achieve the effect of automatic lifting and lowering, thereby achieving the effect of sealing and exposing the bottom of the workpiece 4; when the tension member 27 is another component with a limiting function, the tension member 27 can cooperate with other undulating components, and can slide along the horizontal direction of other undulating components to achieve the effect of automatic lifting and lowering, thereby achieving the effect of sealing and exposing the bottom of the workpiece 4; when the tension member 27 slides along the undulating components, the tension member 27 will have an inclined effect in order to fit against the surface of the undulating components, and the bearing 3 is used to counteract the inclined effect at this time.

[0065] In another embodiment of this application, please refer to Figure 1 , Figure 2 , Figure 8 The top plate 23 is located inside the workpiece 4, and the edge of the top plate 23 matches the inner edge of the workpiece 4.

[0066] Furthermore, the edge of the top plate 23 is provided with a top plate hole 231, which cooperates with the protruding structure inside the workpiece 4.

[0067] In application, the top plate 23 supports the workpiece 4 from the inside, so as to achieve the effect of sealing the bottom of the workpiece 4 by the bottom plate 25; and the top plate hole 231 cooperates with the protruding structure inside the workpiece 4, that is, the protruding structure is located inside the top plate hole 231, so the protruding structure will not cause the inner surface of the workpiece 4 to be higher than the top surface of the top plate 23. The inner surface of the workpiece 4 is in contact with the top surface of the top plate 23 to provide a stable support for the workpiece 4 and a sealing effect for the workpiece 4.
