Description
本發明係一種動態供粉裝置,尤指一種藉由壓料體將粉體壓入卡料部,再由輔助除料單元及除料單元將粉體從旋動單元的周緣上以及卡料部內除去粉體之供粉裝置。 The invention relates to a dynamic powder feeding device, in particular to a powder pressing material into a clamping part by a pressing body, and then the auxiliary removing unit and the removing unit push the powder from the periphery of the rotating unit and the inside of the clamping part. Powder supply device for removing powder.
科技日新月異,在20世紀末的時候,出現許多新的機械製造技術,係如微細加工技術、快速原型製造技術等。其中部分的製造技術係以粉體材料作為原料,來製造機械零件或者成形具有特殊性能的材料。一般為了有效地將粉體進行配給,常會使用螺旋桿進行粉體的輸送,再藉由供粉轉體以將粉體導出,其係如台灣專利公告號第I598213號所公開之技術,主要揭露了供料槽、攪拌轉子、供粉轉子及氣體供給模組等,藉由攪拌轉子攪拌粉體材料且將粉體導入供粉轉子上,進以填入供粉轉子周緣上所設有之供料槽,當供粉轉子轉動而將其供粉槽的開放面置於氣體輸入口之位置時,其氣體供給模組則會提供高壓氣體至氣體輸入口,進而將供粉槽所容納的粉體噴出。 Science and technology are changing rapidly. At the end of the 20th century, many new machine manufacturing technologies appeared, such as micro-machining technology and rapid prototyping technology. Some of these manufacturing technologies use powder materials as raw materials to manufacture mechanical parts or form materials with special properties. Generally, in order to effectively distribute the powder, the powder is often conveyed using a spiral rod, and then the powder is rotated by supplying the powder to export the powder. This is the technology disclosed in Taiwan Patent Publication No. I598213, which is mainly disclosed. The feed tank, agitating rotor, powder supplying rotor, and gas supply module, etc. are used to stir the powder material by the stirring rotor and introduce the powder onto the powder supplying rotor to fill the supply provided on the periphery of the powder supplying rotor. Feed tank, when the powder supply rotor is rotated and the open surface of the powder supply tank is placed at the gas input port, its gas supply module will provide high pressure gas to the gas input port, and then the powder contained in the powder supply tank Body squirting.
然而,雖台灣專利公告號I598213所公開之技術可將進行粉體供給之作用,當粉體填入供粉槽內時,由於堆積的密度及比重不同且粉體顆粒大小不一,並無法有效均勻所填入的粉體量,另外,因供粉槽係為與攪拌轉子相平行之凹槽,故當粉體導入時並無法連續地填入供粉槽內, 而是間斷性地將粉體導入,又因粉體本身重量過輕,故當粉體導入供料槽時則會因供粉轉子之非供粉槽的部位撞擊粉體而使得粉體飄散於供粉槽外,又因粉體本身容易吸潮而具有沾黏性,使得粉體沾黏於供粉槽內而不被高壓氣體噴出。 However, although the technology disclosed in Taiwan Patent Publication No. I598213 can supply powder, when the powder is filled into the powder supply tank, it is not effective because the density and specific gravity of the pile are different and the particle size of the powder is different. The powder is filled evenly. In addition, the powder supply tank is a groove parallel to the stirring rotor, so when the powder is introduced, it cannot be continuously filled into the powder supply tank. Instead, the powder is introduced intermittently, and because the powder itself is too light, when the powder is introduced into the feed tank, the powder will be scattered by the parts of the powder supply rotor that are not in the powder supply tank. Outside the powder supply tank, because the powder itself is easy to absorb moisture, it has stickiness, which makes the powder stick to the powder supply tank without being sprayed by high-pressure gas.
如此,台灣專利公告號I598213並無法有效地控制粉體導出量,且當粉體沾黏於相關設備上時,則易有損壞設備之可能,另外若粉體飄散至空中而以影響環境時,則可能引起粉塵汙染,甚者,則有引起塵爆之可能。因此,本發明人係發明出一種動態供粉裝置,進以改善上述所提及之技術問題。 In this way, Taiwan Patent Bulletin No. I598213 cannot effectively control the amount of powder to be exported, and when the powder adheres to related equipment, it is likely to damage the equipment, and if the powder is scattered into the air to affect the environment, It may cause dust pollution, or even it may cause dust explosion. Therefore, the inventor has invented a dynamic powder supply device to improve the technical problems mentioned above.

請參閱圖1及圖5,其係為本發明立體圖、結構示意側視圖、作動狀態示意圖、部分示意圖及部分立體示意圖,如圖所示,本發明之動態供粉裝置係包括有本體10,本體10一端設有進料體20,本體另端設有出料部11,其進料體20係與出料部11內部相連通,係透過進料體20直接將粉體導入本體10內,進料體20之頂端上則設有進料體入料部21,進料體20底端上則設有進料體出料部22,以透過進料體入料部21將粉體導入,再由進料體出料部22將粉體導出,而進料體20內部進一步還設有引導部23,以使得粉體透過進料體入料部21導入時可有效藉由引導入將粉體導至進料體出料部22上,另外,進料體20一面上還與設有一震動體24,其震動體24可使得該進料體20震動,因粉體本身重量較輕,故當進料體20因震動體24進行震動而相對震動時,粉體則可更有效地落入進料體出料部22上。 Please refer to FIG. 1 and FIG. 5, which are a perspective view, a schematic side view of the structure, a schematic view of an operating state, a partial schematic view, and a partial perspective view. As shown in the figure, the dynamic powder supply device of the present invention includes a body 10 10 is provided with a feeding body 20 at one end and a discharging part 11 at the other end of the body. The feeding body 20 is in communication with the inside of the discharging part 11 and the powder is directly introduced into the body 10 through the feeding body 20, and On the top of the material body 20, there is a material body feeding portion 21, and on the bottom end of the material body 20, a material body discharging portion 22 is provided to introduce the powder through the material body feeding portion 21, and then The powder is led out by the feeding body discharging part 22, and a guide part 23 is further provided inside the feeding body 20, so that when the powder is introduced through the feeding body feeding part 21, the powder can be effectively guided by the feeding It is guided to the discharging part 22 of the feeding body. In addition, a vibrating body 24 is also provided on one side of the feeding body 20, and the vibrating body 24 can cause the feeding body 20 to vibrate. Because the powder itself is relatively light, When the feeding body 20 is relatively vibrated due to the vibration of the vibrating body 24, the powder can fall more effectively onto the feeding body discharge portion 22.
然而,進料體出料部22係設於旋動單元30的周緣相鄰處以使得粉體可有效且準確地落於旋動單元30周緣上,其旋動單元30係與本體10內部相樞接,而旋動單元30一端則與第一驅動體31相連接,以透過第一驅動體31驅使旋動單元30進行旋動;而當粉體落於旋動單元30的周緣上時,因旋動單元30周緣係設有卡料部32,具體來說其卡料部32係為與進料體20相垂直地縱向溝槽且環繞於旋動單元30周緣上,故當粉體落於旋動單元30 周緣上時,大部分之粉體則會落入卡料部32內。 However, the feeding body discharging portion 22 is arranged adjacent to the peripheral edge of the rotating unit 30 so that the powder can effectively and accurately fall on the peripheral edge of the rotating unit 30. The rotating unit 30 is pivoted with the interior of the main body 10. Then, one end of the rotation unit 30 is connected to the first driving body 31 to drive the rotation unit 30 to rotate through the first driving body 31; and when the powder falls on the periphery of the rotation unit 30, The periphery of the rotation unit 30 is provided with a material clamping portion 32. Specifically, the material clamping portion 32 is a longitudinal groove perpendicular to the feeding body 20 and surrounds the periphery of the rotation unit 30. Therefore, when the powder falls on Rotating unit 30 When it is on the periphery, most of the powder will fall into the material holding portion 32.
當旋動單元30旋動時,則會先通過壓料體40的位置,其壓料體40係與本體10相連接且與旋動單元30的周緣相貼合,故當粉體通過壓料體40時,其部分落於旋動單元30周緣上的粉體則會因壓料體40的壓迫而分散落入相鄰近的卡料部32內,而卡料部32內所容納的粉體則會受到壓料體40的壓迫而緊實卡料部內部的粉體。其後,則會再經過輔助除料單元50,其輔助除料單元50係與本體10相連接且設於壓料體40與引導體60之間,輔助除料單元50一端設有輔助除料部51,其輔助除料部51係貼合於旋動單元30之周緣上,故當旋動單元30經過輔助除料單元50之位置時,則可透過輔助除料部51將旋動單元30周緣上所剩餘的粉體刮除以避免粉體沾黏於旋動單元30之周緣上,其被刮除的粉體則會透過引導體60的輔助而落入出料部11的位置上,其引導體60係與本體10相連接,引導體60一面設有一引導出料部61,係透過引導出料部61所具有之弧面結構而將被刮除的粉體導至出料部11的位置上。 When the rotating unit 30 rotates, it will first pass through the position of the pressing body 40. The pressing body 40 is connected to the body 10 and fits with the periphery of the rotating unit 30. Therefore, when the powder passes through the pressing body, In the case of the body 40, the powder that partially falls on the periphery of the rotating unit 30 will be dispersed into the adjacent material holding portion 32 due to the pressure of the material body 40, and the powder contained in the material holding portion 32 Then, the powder inside the clamping portion is compacted by the pressing body 40. After that, it will pass through the auxiliary cutout unit 50. The auxiliary cutout unit 50 is connected to the body 10 and is disposed between the press body 40 and the guide body 60. One end of the auxiliary cutout unit 50 is provided with an auxiliary cutout. Part 51, the auxiliary removing part 51 is attached to the periphery of the rotating unit 30, so when the rotating unit 30 passes the position of the auxiliary removing unit 50, the rotating unit 30 can be passed through the auxiliary removing part 51 The remaining powder on the periphery is scraped off to avoid the powder sticking to the periphery of the rotating unit 30, and the scraped off powder will fall into the position of the discharge part 11 through the assistance of the guide body 60. The guide body 60 is connected to the main body 10. The guide body 60 is provided with a guide discharge portion 61 on one side, and the scraped powder is guided to the discharge portion 11 through the arc surface structure of the guide discharge portion 61. Position.
除料單元70係與本體10相連接且一端設有除料部71,其除料部71係與卡料部32內部相貼合,亦如除料部71貼合於縱向溝槽的凹陷位置上,然而,若除料部71未與卡料部32完全貼合而具有間距時,雖在除料過程中會減少粉體的剔除量,但亦可達成與除料部71欲達成之近似功效。因此,最後當旋動單元30旋動至除料單元70的位置時,卡料部32內所容納的粉體則會因除料部71與卡料部32相貼合或之間具有間距而剔除其粉體,進而將粉體落於出料部11的位置上以有效避免粉體沾黏於卡料部32上。其出料部11係可為完全開放之空間或可為將粉體集中而從出口(可為孔洞或是一 窄小口部)導出的相關結構等。 The cutout unit 70 is connected to the body 10 and is provided with a cutout portion 71 at one end. The cutout portion 71 is attached to the inside of the clamping portion 32, and the cutout portion 71 is attached to the recessed position of the longitudinal groove. Above, however, if the cutout section 71 is not fully bonded to the cutout section 32 and has a gap, although the amount of powder removal will be reduced in the cutout process, it can also achieve an approximation to the cutout section 71. efficacy. Therefore, when the rotation unit 30 is finally rotated to the position of the removing unit 70, the powder contained in the material-receiving portion 32 will be caused by the adhesion of the material-removing portion 71 and the material-receiving portion 32 or a gap between them. The powder is removed, and the powder is dropped on the position of the discharging portion 11 to effectively prevent the powder from sticking to the clamping portion 32. The discharge part 11 can be a completely open space or can be collected from the outlet (which can be a hole or a Narrow mouth)) and related structures.
因此,透過上述作動方式,粉體的導出量則會因卡料部32的深度、寬度以及旋動單元30的轉速來調整,亦如當卡料部32的深度較深或是寬度較寬時,其卡料部32所可容納的粉體量則較大,而若是將旋動單元30的轉速加快時,因作動過程加快,故其被除去的粉體量亦會相對增加。 Therefore, through the above-mentioned operation method, the amount of powder to be discharged will be adjusted according to the depth and width of the material holding portion 32 and the rotation speed of the rotating unit 30, such as when the depth of the material holding portion 32 is deep or the width is wide. The amount of powder that can be held by the material holding portion 32 is relatively large, and if the rotation speed of the rotating unit 30 is increased, the amount of powder that is removed will also be relatively increased because the operation process is accelerated.
另外,在動態給粉之狀態下,其旋動單元30係可依據粉體種類之不同以調整轉速,藉以增進給粉穩定性。再者,若是有規律的間隔給料需求或是不規律的間隔給料需求時,則可透過與除料單元70相連接的第二驅動體72以驅使除料單元70進行前後的位移,進以使得該除料部71與該卡料部32之間具有間距、相互貼合或分離,而其驅動方式包括但不限於滑軌、齒輪或螺旋傳動等方式以驅使除料單元70前後位移。如此,當進行間隔給料之作動時,即可控制除料單元70規律性地前後位移,例如除料單元70以2秒作為間隔給料之標準時,其除料單元70則會先往後位移1秒之後,再往前位移1秒以進行粉體剔除的作動,而其所需剔除的粉體量則可由除料部71與卡料部32相貼合(亦可使得除料部71與卡料部32之間留有一間距以進行粉體剔除的作動,在此係僅以除料部71與卡料部32相貼合為示例)後的停留時間作以判定,亦如當使用者已完成卡料部32的深度及寬度所可容納的粉體量,以及旋動單元30的轉速快慢可剔除的粉體量等計算後,即可明確瞭解若除料部71與卡料部32相貼合後,停留1秒的時間,其可剔除的粉體量為何,藉此即可有效掌握所需的給粉量外,亦可以間隔的方式進行給料。而若是進行不規律的間隔給料作動時,則可設定不同的除料單元70往後位移的時間及後退至最後位置後的停留時間,以及往前位移的時間及往前位 移至除料部71與卡料部32相貼合的位置後所停留的時間,進以進行不規律的間隔給料。 In addition, in the state of dynamic powder feeding, its rotating unit 30 can adjust the rotation speed according to the type of powder, thereby improving the powder feeding stability. Furthermore, if there is a regular interval feeding demand or an irregular interval feeding demand, the second driving body 72 connected to the removal unit 70 can be used to drive the removal unit 70 to move forward and backward, so that There is a distance between the cutout portion 71 and the clipped portion 32, and the drive portion includes but is not limited to a slide rail, a gear, or a screw drive to drive the cutout unit 70 back and forth. In this way, when the interval feeding operation is performed, the removal unit 70 can be controlled to move back and forth regularly. For example, when the removal unit 70 uses 2 seconds as the standard for interval feeding, the removal unit 70 will be shifted back 1 second. After that, it is moved forward for 1 second to perform the powder removal operation, and the amount of powder to be removed can be adhered by the removal section 71 and the clamping section 32 (the removal section 71 and the clamping section can also be made). There is a space between the parts 32 to remove the powder. Here, the dwell time after the removal part 71 and the jamming part 32 are only used as an example) is determined as the same as when the user has completed After calculating the amount of powder that can be held by the depth and width of the clamping portion 32 and the amount of powder that can be removed by the rotation speed of the rotating unit 30, it can be clearly understood that if the removing portion 71 is attached to the clamping portion 32 After the combination, it stays for 1 second, what is the amount of powder that can be removed, so that you can effectively grasp the required amount of powder, and you can also feed in intervals. And if the feeding operation is performed at irregular intervals, different removal times of the removal unit 70 and the residence time after retreating to the final position can be set, as well as the time of forward movement and the forward position. The time to stay after moving to the position where the removing section 71 and the clamping section 32 are in contact with each other, and feeding is performed at irregular intervals.
