Description

Technical Field

[0001] This application relates to the technical field of metal powder processing, and in particular to a drying device. Background Technology

[0002] Drying metal powder is an important process step, especially in powder metallurgy, 3D printing material preparation, and coating production. The main purpose of drying is to remove moisture and volatile substances from metal powders to improve their flowability, storage stability, and subsequent processing performance.

[0003] Currently, a drying device includes a main body with a drying chamber formed within it. A sealing door is hinged to the main body, and a quick clamp connected to the sealing door and connected to the main body is attached to the sealing door. The metal powder to be dried is placed in a placement tray, which is then placed into the drying chamber. Next, the sealing door is rotated to seal the drying chamber, and the quick clamp on the sealing door is then connected to the main body. The metal powder inside the drying chamber will then undergo the drying process.

[0004] When metal powder is being dried in the drying chamber, if the operator accidentally touches the quick clamp, the quick clamp will open, and the sealing door will not be able to seal the drying chamber properly, causing heat to escape and affecting the drying of the metal powder. Utility Model Content

[0005] In order to reduce the impact on the drying of metal powder, this application provides a drying device.

[0006] This application provides a drying device, which adopts the following technical solution:

[0007] A drying device includes a main body and a sealing door. A drying chamber is formed inside the main body, and the sealing door is disposed on the main body and seals the drying chamber. The device also includes a plurality of clamping mechanisms, each of which includes a first connecting block and a clamping block. The first connecting block is disposed on the main body, and the clamping block is rotatably disposed on the first connecting block and is capable of clamping against the sealing door.

[0008] By adopting the above technical solution, when the sealing door seals the drying chamber, the clamping block is rotated to press against the sealing door. With the clamping blocks of multiple clamping mechanisms pressing against the door, the sealing door will maintain the state of sealing the drying chamber. Even if the operator accidentally touches one of the clamping blocks, causing it to fail to press against the sealing door, the clamping blocks of the other clamping mechanisms will still press against the sealing door. Therefore, the phenomenon of the sealing door being opened during metal drying can be reduced, thereby reducing the impact on the drying of metal powder.

[0009] Optionally, the first connecting block is provided with an adjustment mechanism, which includes an adjustment screw, an adjustment nut, and a positioning block. The first connecting block has a threaded hole, the adjustment screw is threadedly connected to the threaded hole, and the abutting block is threadedly connected to the end of the adjustment screw away from the first connecting block. The adjustment nut is fixedly mounted on the first connecting block and the adjustment screw is threadedly connected. The positioning block is mounted on the sealing door, and the abutting block can abut against the positioning block.

[0010] By adopting the above technical solution, when the abutment block is rotated, it drives the adjusting screw to rotate. Because the threaded hole and adjusting nut on the first connecting block are both threadedly connected to the adjusting screw, the adjusting screw will cause the abutment block to move relative to the first connecting block when it rotates. When the abutment block abuts against the positioning block, it presses against the sealing door. The positioning block can reduce the phenomenon of the abutment block pressing against the sealing door too much. The threaded hole and adjusting nut can lock the adjusting screw, so that a certain force needs to be applied when the abutment block rotates. This way, even if the operator accidentally touches the abutment block, it will not rotate. Therefore, the adjustment mechanism can improve the stability of the abutment block pressing against the sealing door and reduce damage to the sealing door.

[0011] Optionally, the sealing door is provided with a sliding groove and a limiting mechanism, which includes a slider, a limiting block and a spring. The slider is slidably disposed in the sliding groove, and the limiting block is disposed on the slider. The limiting block is provided with a limiting groove, and the end of the abutting block away from the first connecting block can be located in the limiting groove. The spring connects the slider and the sealing door.

[0012] By adopting the above technical solution, when the abutting block rotates towards the positioning block, the limiting block moves away from the first connecting block. The limiting block drives the slider to slide in the groove, and the spring undergoes elastic deformation. When the abutting block touches the positioning block, the end of the abutting block away from the adjusting screw enters the limiting groove of the limiting block. At this time, the spring recovers its elastic deformation, and the spring force drives the limiting block towards the first connecting block. Therefore, the limiting mechanism can limit the abutting block when it touches the positioning block, improving the stability of the abutting block when it abuts the sealing door.

[0013] Optionally, the sealed door is provided with a handle, and the side wall of the main body is provided with an auxiliary opening mechanism. The auxiliary opening mechanism includes a second connecting block, a connecting rope, a third connecting block, and a hook. The second connecting block is provided on the side wall of the main body, the connecting rope connects the second connecting block and the third connecting block, and the hook is provided on the third connecting block. The hook can hook the handle.

[0014] By adopting the above technical solution, when the sealing door is in the open state, the end of the hook away from the third connecting block passes through the handle and hooks the handle; therefore, the auxiliary opening mechanism can limit the position of the sealing plate when the sealing door is in the open state, making it convenient for the operator to transfer the tray containing metal powder.

[0015] Optionally, the hook is provided with a limiting component, which includes a first rotating shaft, a limiting block, and a torsion spring. The first rotating shaft is rotatably mounted on the third connecting block, and the limiting block is mounted on the first rotating shaft. The limiting block has a limiting groove, and the end of the hook away from the third connecting block can be located in the limiting groove. The torsion spring is sleeved on the first rotating shaft, with one end connected to the third connecting block and the other end connected to the first rotating shaft.

[0016] By adopting the above technical solution, when the sealing door is in the open state (i.e., the drying chamber is not sealed), first remove the hook from the support hook, then push the limiting block so that the end of the hook away from the third connecting block separates from the limiting groove on the limiting block. At this time, the torsion spring is in a deformed state. Next, let the end of the hook away from the third connecting block pass through the handle, release the limiting block, and the torsion spring restores its elastic deformation. Under the action of the torsion spring's elastic force, the limiting block will return to its original position, allowing the end of the hook away from the third connecting block to re-enter the limiting groove of the limiting block. The limiting component can improve the stability of the hook when it hooks the handle.

[0017] Optionally, the main body has a connecting groove that engages with the second connecting block, and the second connecting block is provided with a fixing mechanism, the fixing mechanism including a fixing block and an adjusting component. There are two fixing blocks, both of which are slidably disposed on the second connecting block. The main body has two fixing grooves, and the two fixing blocks engage with the two fixing grooves respectively. The adjusting component is disposed on the second connecting block, and both fixing blocks are connected to the adjusting component.

[0018] By adopting the above technical solution, the second connecting block is first engaged with the connecting groove on the main body, and then the two fixing blocks are driven to move in opposite directions by adjusting the component, so that the two fixing blocks are engaged with the two fixing grooves.

[0019] Optionally, the adjustment assembly includes a second rotating shaft, an adjustment gear, and an adjustment rack. The second rotating shaft is rotatably mounted on the second connecting block. The adjustment gear is keyed to the second rotating shaft and is located between the two fixed blocks. The two fixed blocks are each provided with an adjustment rack, and both adjustment racks mesh with the adjustment gear.

[0020] By adopting the above technical solution, rotating the second shaft causes the adjusting gear on the second shaft to move the two adjusting racks, which in turn cause the two fixed blocks to move in opposite directions or away from each other.

[0021] Optionally, a support mechanism is provided inside the drying chamber. Each support mechanism includes a first support block, a second support block, a third support block, and a fixing bolt. The first support block is connected to the main body and located inside the drying chamber by the fixing bolt. The second support block is disposed on the first support block, and the third support block is disposed on the second support block. There are two of each of the first, second, and third support blocks. The two first support blocks are respectively disposed on two opposite side walls of the drying chamber, and the two second support blocks are located in the same horizontal plane.

[0022] By adopting the above technical solution, the placement tray containing metal powder is placed on the second support block inside the drying chamber, and the second support block supports the placement tray.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The drying equipment provided in this application can reduce the phenomenon that the sealed door will be opened during the drying of metal, thereby reducing the impact on the drying of metal powder;

[0025] 2. The positioning block reduces the phenomenon of the clamping block pressing too hard against the sealing door. The threaded hole and adjusting nut lock the adjusting screw, so that a certain force needs to be applied when the clamping block rotates. This way, even if the operator accidentally touches the clamping block, it will not rotate. Therefore, the adjustment mechanism can improve the stability of the clamping block when pressing against the sealing door and reduce damage to the sealing door. Attached Figure Description

Detailed Implementation

[0033] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0034] This application discloses a drying device.

[0035] refer to Figure 1 and Figure 2 A drying device includes a main body, a drying chamber formed within the main body, and multiple support mechanisms disposed within the drying chamber; a sealing door is hinged to the main body, the sealing door being able to cover the sealing drying chamber; two clamping mechanisms connected to the sealing door are disposed on the main body, and a limiting mechanism connected to the clamping mechanisms is disposed on the main body; a handle is fixedly disposed on the sealing door, and an auxiliary opening mechanism connected to the handle is disposed on the outer side wall of the main body.

[0036] refer to Figure 2 and Figure 3Each support mechanism includes two first support blocks, which abut against two opposite side walls of the drying chamber. Each first support block is equipped with a fixing bolt, which passes through the first support block and is threaded to the side wall of the drying chamber. Each first support block is vertically fixedly connected to a second support block, and the two second support blocks are located in the same horizontal plane. Each second support block is vertically fixedly connected to a third support block on the side away from the first support block, and the third support block is parallel to the first support block. The side of the second support block near the sealing door is provided with an arc and tilts downward.

[0037] refer to Figure 1 and Figure 4 One of the clamping mechanisms clamps the upper end of the sealing door, and the other clamping mechanism clamps the lower end of the sealing door. Each clamping mechanism includes a mounting block with mounting bolts that pass through the mounting block and are threaded to the main body; a cylindrical first connecting block is fixedly connected to the side of the mounting block away from the main body.

[0038] The first connecting block has a threaded hole at one end away from the mounting block. An adjustment mechanism is provided on the first connecting block, which includes an adjusting screw threadedly connected to the threaded hole. An adjusting nut is fixedly connected to one end of the first connecting block away from the mounting block, and the adjusting nut is threadedly connected to the adjusting screw. A clamping block is fixedly connected to one end of the adjusting screw away from the mounting block. A positioning block is fixedly connected to the sealing door, and the clamping block can clamp against the positioning block.

[0039] When the sealing door covers and seals the drying chamber, the abutment block is rotated, which drives the adjusting screw to rotate. Because the threaded hole on the first connecting block and the adjusting nut are both threadedly connected to the adjusting screw, the adjusting screw will cause the abutment block to move relative to the first connecting block when the adjusting screw rotates. When the abutment block abuts against the positioning block, the abutment block presses against the sealing door.

[0040] refer to Figure 1 and Figure 4 The sealing door has a sliding groove and a limiting mechanism. The limiting mechanism includes a slider that slides within the sliding groove, a limiting block integrally formed on the slider, and a limiting groove on the limiting block. The end of the abutment block away from the adjusting screw can be located within the limiting groove. A chamfer is formed on the side wall of the limiting block. A spring is installed within the sliding groove, with one end connected to the slider and the other end connected to the sealing door.

[0041] When the abutting block rotates towards the positioning block, it first contacts the chamfer on the limiting block and presses against it, causing the limiting block to move away from the first connecting block. The limiting block then drives the slider to slide in the groove, compressing the spring. When the abutting block contacts the positioning block, the end of the abutting block away from the adjusting screw enters the limiting groove of the limiting block. At this point, the spring returns to its elastic deformation, and the spring force drives the limiting block towards the first connecting block.

[0042] refer to Figure 1 , Figure 2 and Figure 5 The main body has a connecting groove on its outer side wall, and two fixing grooves are formed on the side wall of the connecting groove. The auxiliary opening mechanism includes a second connecting block that engages with the connecting groove. The second connecting block has an adjustment cavity and two sliding holes communicating with the adjustment cavity. A fixing mechanism is provided on the second connecting block, which includes two fixing blocks. The two fixing blocks are slidably disposed in the two sliding holes, and the ends of the two fixing blocks that are far apart from each other are engaged with the two fixing grooves. The ends of the two fixing blocks that are close to each other are located in the adjustment cavity. An adjustment assembly is provided on the second connecting block. The adjustment assembly includes a second rotating shaft rotatably connected to the second connecting block. One end of the second rotating shaft is located in the adjustment cavity, and the end face of the other end is coplanar with the side wall of the second connecting block. An adjustment gear is keyed to the second rotating shaft located in the adjustment cavity. The adjustment gear is located between the two fixing blocks. An adjustment rack that meshes with the adjustment gear is integrally provided on the side of the two fixing blocks that are close to each other. A countersunk hole is formed at the end of the second rotating shaft that is far away from the adjustment gear, which engages with an Allen wrench.

[0043] First, engage the second connecting block with the connecting groove on the main body. Then, engage the Allen wrench with the countersunk hole on the second rotating shaft. Rotate the Allen wrench, which drives the second rotating shaft to rotate. The second rotating shaft drives the adjusting gear to rotate, which drives the two adjusting racks to move. The two adjusting racks drive the two fixed blocks to move in opposite directions, so that the two fixed blocks engage with the two fixed grooves.

[0044] refer to Figure 1 , Figure 5 and Figure 6 A connecting rope is fixedly connected to the second connecting block. A third connecting block is fixedly connected to the end of the connecting rope away from the second connecting block. A hook is fixedly connected to one side of the third connecting block, and the hook can hook onto the handle. A limiting component is provided on the third connecting block. The limiting component includes a first rotating shaft rotatably connected to the third connecting block, a limiting block fixedly connected to the first rotating shaft, and a limiting groove formed at the end of the limiting block away from the first rotating shaft, allowing the end of the hook away from the third connecting block to be located within the limiting groove. A torsion spring is sleeved on the first rotating shaft, with one end connected to the first rotating shaft and the other end connected to the third connecting block. A support hook for the hook to engage is fixed to the second connecting block.

[0045] When the sealing door is in the open state (i.e., the drying chamber is not sealed), first remove the hook from the support hook, then push the limiting block so that the end of the hook away from the third connecting block separates from the limiting groove on the limiting block. At this time, the torsion spring is in a deformed state. Next, let the end of the hook away from the third connecting block pass through the handle, release the limiting block, and the torsion spring returns to its elastic deformation. Under the action of the torsion spring's elastic force, the limiting block will return to its original position, allowing the end of the hook away from the third connecting block to re-enter the limiting groove of the limiting block.

[0046] The implementation principle of a drying device according to an embodiment of this application is as follows: when it is necessary to dry metal powder, the sealing door is first opened, the hook is hooked onto the handle, and the end of the hook away from the third connecting block is located in the limiting groove of the limiting block; then the placement tray containing metal powder is placed on the second support block in the drying chamber, and the second support block supports the placement tray.

[0047] Next, push the limiting block so that the end of the hook away from the third connecting block is no longer in the limiting groove, separate the hook from the handle on the sealing door, and place the hook on the support hook.

[0048] Then, cover the sealing drying chamber with the sealing door, and then rotate the abutment block so that the abutment block abuts against the positioning block, and the end of the abutment block away from the adjusting screw is located in the limiting groove of the limiting block. At this time, the abutment block will be in the state of abutting against the sealing door.

[0049] In this application, the method for drying the metal powder is hot air drying, which is prior art and will not be described in detail here.

[0050] 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.
