Description

Technical Field

[0001] This application relates to the technical field of screening equipment, and particularly relates to an anti-misalignment device for a metal powder screening equipment. Background Art

[0002] The metal powder screening process is mainly achieved through the movement of an oscillating screen. The metal powder is placed on the screen of the oscillating screen, and then, through the vibration force of the oscillator and the aperture size of the screen, the powder undergoes relative movement on the screen. In this way, the powder will pass through the screen meshes of different sizes according to its particle size, thus achieving the separation purpose.

[0003] During the screening process, a bucket for receiving the screened powder needs to be placed at the discharge opening of the equipment. The bucket is generally placed naturally and will vibrate during the screening operation. Therefore, the placed bucket is very likely to be misaligned with the discharge opening, affecting the discharging effect. For this reason, an anti-misalignment device for a metal powder screening equipment is proposed to solve the above technical problems. Utility Model Content

[0004] One of the purposes of this application is to provide an anti-misalignment device for a metal powder screening equipment.

[0005] To achieve the above purpose, the technical solution adopted in this application is: an anti-misalignment device for a metal powder screening equipment, including a base, a screening device, a clamping device, a blocking device, and a bucket. The screening device is installed at the top of the base, the clamping device is installed on the base, the blocking device is installed at the discharge opening of the screening device and cooperates with the clamping device, and the bucket is placed on the base and below the discharge opening; when the clamping device is suitable for clamping and fixing the bucket, the blocking device is suitable for being driven by the clamping device to open the discharge opening.

[0006] Preferably, the blocking device includes a sealing plate, and the sealing plate is elastically slidably installed at the bottom end of the discharge opening; when clamping the bucket, the sealing plate is suitable for sliding under the drive of the clamping device and being misaligned with the discharge opening to open the discharge opening.

[0007] Preferably, the clamping device includes a bidirectional screw rod and a pair of clamping members. The bidirectional screw rod is rotatably installed in the base, the clamping members are slidably installed in the base and cooperate with both sides of the bidirectional screw rod. One of the clamping members is provided with a driving rod; when clamping the bucket, the clamping members are suitable for moving relatively under the drive of the bidirectional screw rod and abutting against the bucket, and the driving rod is suitable for being driven by the clamping member to push the sealing plate.

[0008] Preferably, the driving rod includes a vertical rod, a horizontal rod, and a limiting component. The vertical rod is vertically installed on one of the clamping members, and the horizontal rod is horizontally slidably installed at the top of the vertical rod and corresponds to the sealing plate. When adjusting the horizontal rod, the limiting component is adapted to unlock the horizontal rod. When the adjustment of the horizontal rod is completed, the limiting component is adapted to lock the horizontal rod.

[0009] Preferably, the limiting component includes a limiting screw rod, and the limiting screw rod is in threaded cooperation with the top of the vertical rod. When the horizontal rod is locked, the limiting screw rod is adapted to rotate spirally until it abuts against the horizontal rod. When the horizontal rod is adjusted, the limiting screw rod is rotated spirally in the reverse direction so that the limiting screw rod moves away from the horizontal rod.

[0010] Preferably, a plurality of limiting holes are provided on the horizontal rod. When the horizontal rod is locked, the limiting screw rod is engaged with the corresponding limiting holes.

[0011] Preferably, clamping plates are elastically and slidably installed on the opposite sides of the two clamping members, so as to elastically clamp the barrel body.

[0012] Preferably, the clamping plate has an arc-shaped structure adapted to the barrel body. When clamping the barrel body, the arc-shaped clamping plate is adapted to centeringly clamp the barrel body.

[0013] Compared with the prior art, the beneficial effects of the present application are as follows:

[0014] By providing a clamping device and a plugging device, the clamping device can clamp and fix the placed barrel body, so that the placed barrel body will not be misaligned with the feeding port under vibration. Moreover, only when the barrel body is clamped, the feeding port will be opened under the action of the plugging device, which can prevent the staff from forgetting to clamp and fix the barrel body, and further ensure the stability during feeding.

Specific embodiments

[0021] Next, in combination with specific embodiments, the present application will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0022] In the description of the present application, it should be noted that for orientation terms, if there are terms such as "center", "transverse", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation and position relationship are based on the orientation or position relationship shown in the drawings, which are only for facilitating the description of the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of the present application.

[0023] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence.

[0024] One preferred embodiment of the present application is as Figures 1 to 5 shown. An anti-misoperation device for a metal powder screening device includes a base 1, a screening device 2, a clamping device 5, a blocking device 3, and a barrel body 4. Among them, the screening device 2 and the clamping device 5 are both installed on the base 1, the blocking device 3 is installed at the material discharge port 201 of the screening device 2 and cooperates with the clamping device 5, and the barrel body 4 is placed on the base 1 and is located below the material discharge port 201.

[0025] It can be understood that when performing screening and material receiving, the barrel body 4 is first placed on the base 1 and corresponds to the lower part of the material discharge port 201 (material discharge pipe), and then the placed barrel body 4 is clamped and fixed by the clamping device 5, so that the barrel body 4 will not be displaced due to the influence of vibration during material receiving, that is, the barrel body 4 and the material discharge port 201 will not be misaligned, so as to maintain the stability of the placement of the barrel body 4.

[0026] Of course, during the process of the clamping device 5 clamping the barrel body 4, at the same time, the clamping device 5 also acts on the blocking device 3, so that the blocking device 3 opens the blanking port 201, that is, the sieved powder will fall from the opened blanking port 201. Similarly, conversely, when the clamping device 5 releases the barrel body 4, the blanking port 201 will be blocked by the blocking device 3 at this time.

[0027] It should be noted that when the barrel body 4 is not clamped and fixed (released), the blanking port 201 is in a closed state at this time, and then the replacement between the full barrel body 4 and the new barrel body 4 can be carried out. When the barrel body 4 is clamped and fixed for receiving materials, the blanking port 201 will be opened at this time, and then the receiving material operation can be carried out.

[0028] That is to say, the clamping device 5 and the blanking port 201 are linked. Only when the barrel body 4 is clamped, the blanking port 201 will be opened; when the barrel body 4 is released, the blanking port 201 will be closed. On the one hand, this facilitates the stability of the barrel body 4 when receiving materials. On the other hand, when replacing the full barrel body 4, there is no need for the staff to manually close the blanking port 201, which greatly improves the work efficiency. Moreover, only when the barrel body 4 is clamped, the blanking port 201 will be opened under the action of the blocking device 3, which can prevent the staff from forgetting to clamp and fix the barrel body 4, and further ensure the stability during blanking.

[0029] One embodiment of the present application is as Figure 3 shown, the blocking device 3 includes a sealing plate 301, and the sealing plate 301 can be elastically slidably installed at the bottom end of the blanking port 201 through a (spring).

[0030] It can be understood that when the barrel body 4 is clamped, the sealing plate 301 will slide under the drive of the clamping device 5 at this time, so that the sealing plate 301 is misaligned with the blanking port 201, and in this way, the sealing plate 301 will lose the blocking effect on the blanking port 201, so that the blanking port 201 is opened. Similarly, when the barrel body 4 is released, the sealing plate 301 will lose the action of the clamping device 5 at this time, and then the sealing plate 301 will reset under the elastic force of the spring, that is, the sealing plate 301 will move back until it blocks the blanking port 201, as Figure 4 shown.

[0031] In this embodiment, as Figure 5 shown, the clamping device 5 includes a bidirectional lead screw 501 and a pair of clamping members 502. The bidirectional lead screw 501 is rotatably installed in the base 1, and the clamping members 502 are slidably installed in the base 1 and cooperate with both sides of the bidirectional lead screw 501. One of the clamping members 502 is provided with a driving rod 6.

[0032] It is understandable that when clamping the barrel body 4, the staff can rotate the bidirectional screw 501 (forward), and the bidirectional screw 501 can act on the two clamping members 502 to move relative to each other until they abut against the barrel body 4, so as to clamp and fix the barrel body 4; and at the same time, the driving rod 6 will push the sealing plate 301 driven by the clamping member 502 to open the feeding port 201. Similarly, when the barrel body 4 is loosened, the bidirectional screw 501 can be rotated (reverse) at this time, so that the two clamping members 502 move relative to each other and move away from the barrel body 4, and at the same time, the driving rod 6 will also move away from the sealing plate 301, and then the sealing plate 301 will move and reset under the elastic force of the spring.

[0033] After applying the above embodiment, there will be such shortcomings when using it: we know that different barrel bodies 4 have different sizes, and when clamping and fixing the barrel body 4, the moving distances of the two clamping parts 502 will be different, while the moving opening distances of the sealing plate 301 are the same, and then the two cannot cooperate well to open the discharge port 201.

[0034] In order to solve the above technical problems, one of the embodiments of the present application is as follows: Figure 3 As shown, the driving rod 6 includes a vertical rod 601 , a horizontal rod 602 and a limit assembly 603 . The vertical rod 601 is vertically mounted on one of the clamping members 502 , and the horizontal rod 602 is horizontally slidably mounted on the top of the vertical rod 601 and corresponds to the sealing plate 301 .

[0035] It is understandable that the cross bar 602 can be slidably adjusted at this time, that is, the cross bar 602 can be adjusted and adapted according to the sizes of different barrel bodies 4, thereby ensuring that when the barrel body 4 is clamped and fixed, the cross bar 602 can move and cooperate with the sealing plate 301 to open the discharge port 201.

[0036] Specifically, when the crossbar 602 is adjusted, the limit assembly 603 can unlock the crossbar 602. When the crossbar 602 is adjusted, the limit assembly 603 can lock the crossbar 602.

[0037] As a further description of the above embodiment: the limiting assembly 603 includes a limiting screw rod, and the limiting screw rod is matched with the top end of the vertical rod 601 through a thread.

[0038] It can be understood that when the cross bar 602 is locked, the limit screw can be rotated (forward) in a spiral manner at this time, and the limit screw will move downward until it abuts against the cross bar 602 to achieve the limitation of the cross bar 602. Similarly, conversely, when the cross bar 602 is adjusted, the limit screw can be rotated (backward) in a spiral manner at this time so that the limit screw moves upward and away from the cross bar 602 to achieve the loosening of the cross bar 602. At this time, the cross bar 602 can be adjusted by sliding.

[0039] Furthermore, generally, there are specific several models for the barrel body 4 for holding, and thus the position of the cross bar 602 is fixed each time it is adjusted. Therefore, in order to improve the rapid adjustment of the cross bar 602, a plurality of limit holes 604 can be provided on the cross bar 602. It can be understood that different limit holes 604 correspond to different models of the barrel body 4. Therefore, when adjusting and locking the cross bar 602, we can quickly match the limit screw with the corresponding limit hole 604, which greatly improves the adjustment speed.

[0040] One embodiment of the present application is as Figure 5 shown, clamping plates 503 are elastically slidably mounted on the opposite sides of the two clamping members 502 (through springs). It can be understood that when the barrel body 4 is not clamped, the two clamping plates 503 are in a state of being away from the clamping members 502; when the barrel body 4 is clamped, as Figure 2 shown, the two clamping plates 503 will approach the clamping members 502 under the extrusion force, and thus the spring is in an elastically deformed state to achieve the elastic clamping of the barrel body 4, preventing the hard extrusion damage between the clamping members 502 and the barrel body 4. On the other hand, the elastic clamping can absorb the possible minute vibrations generated by the barrel body 4 during the clamping process, further enhancing the clamping stability.

[0041] Furthermore, the clamping plate 503 can adopt an arc-shaped structure adapted to the barrel body 4.

[0042] It can be understood that when the barrel body 4 is clamped, the clamping plate 503 can increase the contact area with the barrel body 4 at this time, and thus can improve the clamping effect. On the other hand, the arc-shaped clamping plate 503 can also perform centering clamping on the barrel body 4; by way of example, assuming that the barrel body 4 is not initially placed directly below the blanking port 201, but there is a certain deviation between the barrel body 4 and the blanking port 201, when the two clamping plates 503 approach each other, the arc-shaped clamping plate 503 can move the barrel body 4 towards the central position so that the barrel body 4 is located directly below the blanking port 201 after being clamped.

[0043] It should be noted that since the initially placed barrel body 4 is an empty barrel and has a relatively light mass, when the clamping plate 503 approaches the barrel body 4, the elastic force of the spring at this time is sufficient to support the clamping plate 503 to push the barrel body 4. When the barrel body 4 is centered and clamped, the two clamping members 502 continue to move relative to each other, and the clamping plate 503 will maintain the mating state with the barrel body 4, thereby causing the spring to deform to achieve elastic clamping and fixing of the barrel body 4.

[0044] The working principle of the present utility model is as follows:

[0045] First, place the barrel body 4 on the base 1 and below the blanking port 201. Subsequently, the staff can rotate the bidirectional lead screw 501, and the bidirectional lead screw 501 acts on the two clamping members 502 to move relative to each other, so that the two clamping plates 503 elastically center and clamp the barrel body 4. At the same time, during the movement of the clamping member 502, the driving rod 6 will also move accordingly, and the driving rod 6 will push the sealing plate 301 to slide, so that the blanking port 201 is opened. In this way, on the one hand, it can prevent the barrel body 4 from being misaligned with the blanking port 201 under the action of vibration; it can also prevent the negligence of the staff when placing the barrel body 4, so that the barrel body 4 is misaligned with the blanking port 201. Because only when the barrel body 4 is clamped and fixed and facing the blanking port 201, the blanking port 201 is in the open state at this time.

[0046] The above describes the basic principle, main features and advantages of the present application. Those skilled in the art of this industry should understand that the present application is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present application.
