Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, and more specifically to a manual operation component of a powder cleaning device. Background Technology

[0002] Manual powder cleaning of 3D printed parts refers to the cleaning process carried out by operators without the aid of automated equipment (such as air jet powder cleaners or ultrasonic vibration tables). This process is commonly seen in the prototype verification stage or for cleaning parts of the workpiece that are difficult to handle.

[0003] The powder cleaning operation is carried out in a powder hopper with an internal cavity. Without opening the hopper, a through-hole is typically made, and a flexible, well-sealed glove is installed at the through-hole. The glove is placed inside the hopper, with the wrist cuff fixed to the inner end of the through-hole. When manual powder cleaning is required, the operator inserts their hand into the glove and manually performs the cleaning process under the protection of the glove.

[0004] Manual powder cleaning is only used as an auxiliary method in the overall powder cleaning operation. The equipment mainly relies on high-pressure air nozzles and other mechanisms installed inside the powder tank for powder cleaning. As can be seen, during normal powder cleaning, the rapid airflow generated inside the powder tank will cause the gloves to swing violently. After prolonged powder cleaning operations, the gloves are prone to damage and have poor stability. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by providing a manual operation component for a powder cleaning device that allows for convenient and stable powder cleaning of workpieces inside the powder hopper without opening the hopper.

[0006] To achieve the above objectives, this utility model can be implemented through the following technical solutions:

[0007] A manual operation component for a powder cleaning device, the powder cleaning device including a powder bucket with an internal cavity, characterized in that the manual operation component is disposed on the side of the powder bucket, the manual operation component includes an operation port, an operation box, a glove, an inner cover plate and an outer cover plate, the operation port penetrates through the side of the powder bucket, the operation box has an internal cavity and is fixedly connected to the operation port.

[0008] The outer end of the operation box is located outside the powder bucket and has a through hole at its outer end;

[0009] The inner end of the operation box is located inside the powder bucket and has a through hole 2 at its inner end;

[0010] The aforementioned gloves are located inside the control box, and the wrist opening of the gloves is fixed to a through hole;

[0011] The outer cover plate is connected to the outer end of the control box and allows the through hole one to be opened and closed. The inner cover plate is connected to the inner end of the control box and allows the through hole two to be opened and closed.

[0012] In the manual operation component of the powder cleaning device described above, there are two through holes one, which are arranged adjacent to each other on the left and right, and there are two through holes two, which are arranged in a one-to-one correspondence with through holes one.

[0013] In the manual operation component of the aforementioned powder cleaning device, the outer cover plate is long and hinged to the upper part of the control box. In the initial state, the outer cover plate is lowered to cover the two through holes.

[0014] In the manual operation component of the aforementioned powder cleaning device, the operation box also has a latch, which can be engaged and connected to the lower part of the outer cover plate when the outer cover plate covers the two through holes.

[0015] In the manual operation component of the aforementioned powder cleaning device, the upper part of the outer cover plate has two hinges, which are respectively located at the operation box above the corresponding through hole.

[0016] In the manual operation component of the aforementioned powder cleaning device, there are two latches, each located at the operation box below the corresponding through hole.

[0017] In the manual operation component of the aforementioned powder cleaning device, the inner cover plate is hinged to the inner end of the operation box via a damping hinge.

[0018] In the manual operation component of the aforementioned powder cleaning device, the hinge between the inner cover plate and the inner end of the operation box is located on the side of the inner cover plate.

[0019] In the manual operation component of the aforementioned powder cleaning device, the hinge point between the inner cover plate and the inner end of the operation box is close to the side of the operation box.

[0034] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0035] like Figure 1-8 As shown, the powder cleaning device includes a powder bucket 3 with an internal cavity.

[0036] The manual operation component of this powder cleaning device is located on the side of the powder tank 3. The manual operation component includes an operation port 41, an operation box 42, a glove 43, an inner cover plate 44, and an outer cover plate 45. The operation port 41 penetrates the side of the powder tank 3. The operation box 42 has a hollow interior and is fixedly connected to the operation port 41.

[0037] The outer end of the operation box 42 is located outside the powder bucket 3 and has a through hole 4211 at its outer end;

[0038] The inner end of the operation box 42 is located inside the powder bucket 3 and has a through hole 4221 at its inner end;

[0039] The aforementioned glove 43 is located inside the control box 42 and the wrist opening of the glove 43 is fixed to the through hole 4211.

[0040] The outer cover plate 45 is connected to the outer end of the operation box 42 and allows the through hole 4211 to be opened and closed. The inner cover plate 44 is connected to the inner end of the operation box 42 and allows the through hole 4221 to be opened and closed.

[0041] When the outer cover plate 45 closes the through hole 4211 and the inner cover plate 44 closes the through hole 4221, the glove 43 is inside the sealed operating box 42. At this time, the workpiece in the powder bucket 3 is cleaned by a high-pressure air nozzle, and the glove inside the operating box 42 will not be affected by the airflow inside the powder bucket 3.

[0042] Conversely, when both the inner cover plate 44 and the outer cover plate 45 are opened, the operator's hands can be inserted into the glove 46. The glove's insulating effect allows for auxiliary powder cleaning operations.

[0043] In this embodiment, glove 46 is an existing rubber glove. Since glove 46 is a commercially purchased item, the technical features of glove 46 will not be described in detail in this embodiment.

[0044] There are two through holes 4211, which are arranged adjacent to each other on the left and right. There are two through holes 4221, which are arranged in a one-to-one correspondence with through holes 4211.

[0045] Two through holes 4211 are used to accommodate the operator's two hands. Of course, through hole 4221 is set one-to-one with through hole 4211, so that the gloves 46 inside the operating box 42 can be stably extended after being put on by the operator.

[0046] The outer cover plate 45 is long and plate-shaped. The upper part of the outer cover plate 45 is hinged to the operation box 42. In the initial state, the outer cover plate 45 is swung down to cover the two through holes 4211.

[0047] The hinge between the outer cover plate 45 and the control box 42 has a damped hinge. That is to say, the outer cover plate 45 can be positioned at any opening angle.

[0048] To prevent the outer cover plate 45 from suddenly swinging down during operation.

[0049] The operating box 42 also has a latch 47, which can be fastened to the lower part of the outer cover plate 45 when the outer cover plate 45 covers the two through holes 4211.

[0050] The outer cover plate 45 can be locked in place by the latch 47. In other words, the outer cover plate 45 can always keep the through hole 4211 closed.

[0051] In this embodiment, the latch 47 includes a lock base 471 and a lock plate 472. The lock base 471 is fixed on the operating box 42, and the inner end of the lock plate 472 is hinged to the lock base 471. In the initial state, the lock plate 472 is away from the outer cover plate 45. When the outer end of the lock plate 472 swings onto the outer cover plate 45, the latch 47 can lock with the lower part of the outer cover plate 45.

[0052] The outer cover plate 45 has two hinge parts 451 on its upper part, and the two hinge parts 451 are respectively located at the operation box 42 on the upper part of the corresponding through hole 4211.

[0053] Since the outer cover plate 45 is relatively large in length, the entire outer cover plate 45 can be stably hinged to the operating box 42 through the hinge parts 451 located at both ends of the outer cover plate 45.

[0054] There are two latches 47, and the two latches 47 are respectively located at the operation box 42 below the corresponding through hole 4211.

[0055] Similarly, since the outer cover plate 45 is relatively large in length, it can be stably locked by two latches 47.

[0056] The inner cover plate 44 is hinged to the inner end of the control box 42 via a damping hinge.

[0057] Under the action of the damping hinge, the inner cover plate 44 can be positioned in any open position. Of course, with the application of a sufficiently large force, the inner cover plate 44 can be made to swing.

[0058] In this embodiment, the inner cover plate 44 has a protruding handle 441 on its inner side. The inner cover plate 44 can be easily pulled by the handle 441, and the inner cover plate 44 can stably close the through hole 4221.

[0059] The hinge between the inner cover plate 44 and the inner end of the operation box 42 is located on the side of the inner cover plate 44.

[0060] The hinge point between the inner cover plate 44 and the inner end of the control box 42 is close to the side of the control box 42.

[0061] This structure keeps the hinge points of the two inner cover plates 44 as far apart as possible to avoid mutual interference.

[0062] The operating box 42 includes a first shell 421 and a second shell 422, both of which are hollow inside. The first shell 421 is fixed to the outside of the powder bucket 3. The first through hole 4211 and the outer cover plate 45 are both located on the first shell 421. There are two second shells 422, which are fixed to the inside of the powder bucket 3. The first shell 421 and the second shell 422 are connected. The second through hole 4221 is formed at the outer end of the second shell 422. The inner cover plate 44 is hinged to the outer end of the second shell 422.

[0063] This structure allows the glove 46 to be stably positioned within the cavity between housing 1 421 and housing 2 422 during storage.

[0064] Since the gloves of this powder cleaning device are located inside the control box, and both the inner and outer covers are closed during normal powder cleaning operations, the gloves will not be affected during the powder cleaning process.

[0065] When manual powder cleaning is required, after opening the inner and outer cover plates, the operator can put their hands inside gloves. With the isolation provided by the gloves, the operator can easily perform the corresponding powder cleaning operation on the workpieces inside the powder bucket.

[0066] After manual operation is completed, the gloves retract into the control box, and the inner and outer covers are closed. Once these actions are completed, because the gloves are inside the sealed control box, the powder cleaning process performed by mechanisms such as the high-pressure air nozzle will not affect them. It exhibits high stability and has significant practical value.

[0067] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.

[0068] The technical solutions in the above embodiments have clearly and completely described the content of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
