該活動部(53)具有一呈L形之活動側體(531)，一頂端呈梯狀之片狀延伸體(532)則係以一側片面貼靠於該活動側體之一第三板(5311)上，一槽口朝上之限位槽(533)係凹設於該延伸體(532)傾斜之頂端上，一柱栓狀之限位體(534)則固設於該活動側體之第三板(5311)上，並位於該限位槽(533)之槽開口方向上，二耳片狀之第二擋體(535)係突設於該活動側體之第三板(5311)的底端上，並位於該延伸體(532)之下方，一片狀之第三擋體(536)則突設於該延伸體(532)之底端，並位於該些第二擋體(535)之上方，二彼此平行之長條狀調整孔(537)係分別貫設於該活動側體之第三板(5311)與該延伸體(532)上，並沿平行於該集塵室(52)上方開口之方向延伸適當之長度，二定位栓(538)係分別穿經各該調整孔(533)地螺設於該箱蓋(322)上，據以將該活動側體(531)與該延伸體(532)結合於該箱蓋(322)上，同時使該活動部(53)得以隨著該箱蓋(322)在該蓋合位置與該開啟位置間之轉動，使該活動側體(531)同步地在一相鄰位置與一遠離位置間移動；The movable portion (53) has an L-shaped movable side body (531), and a sheet-like extension body (532) with a ladder-shaped top end is attached to a third plate of the movable side body with one side. On (5311), a limiting slot (533) with an upward notch is recessed on the inclined top end of the extension body (532), and a stud-shaped limiting body (534) is fixed on the movable side On the third plate (5311) of the body and located in the direction of the opening of the limiting groove (533), a two-ear piece-shaped second stopper (535) is protruding from the third plate ( 5311) and located below the extension body (532), a piece-shaped third block (536) protrudes from the bottom end of the extension body (532) and is located at the second block Above the body (535), two parallel elongated adjustment holes (537) are respectively penetrated through the third plate (5311) of the movable side body and the extension body (532), and are parallel to the set The direction of the upper opening of the dust chamber (52) extends an appropriate length, and two positioning bolts (538) are screwed on the box cover (322) through the adjustment holes (533) respectively, so that the movable side body (531) is combined with the extension body (532) on the box cover (322), and at the same time, the movable portion (53) can follow the rotation of the box cover (322) between the closed position and the open position, Make the movable side body (531) move synchronously between an adjacent position and a distant position;
如圖5所示，當該箱蓋(322)位於該蓋合位置上時，係帶動該活動側體(531)位於該相鄰位置，使該活動側體(531)之第三板與第四板(5311)(5312)鄰靠於該底座之第三側(5113)與第四側(5114)上，據以將該集塵室(52)在水平方向上之開口封閉，使該集塵室(52)呈上方透空的筒形容納空間；As shown in Figure 5, when the box cover (322) is at the closing position, the movable side body (531) is driven to be located at the adjacent position, so that the third plate of the movable side body (531) and the third plate The four plates (5311) (5312) abut on the third side (5113) and the fourth side (5114) of the base, so as to close the opening of the dust collection chamber (52) in the horizontal direction to make the collection The dust room (52) is a cylindrical accommodating space with a hollow above;
如圖6所示，當該箱蓋(322)位於該開啟位置上時，該活動側體(531)則位於遠離位置上，而與該底座(51)相隔開來，使該集塵室(52)在水平方向上復呈透空；As shown in Figure 6, when the box cover (322) is located at the open position, the movable side body (531) is located at a distant position, and is separated from the base (51), so that the dust collection chamber ( 52) Reappear transparently in the horizontal direction;
更進一步地，如圖7及圖8所示，當該工作台(40)在因應工作條件之需求而透過習知技術改變本身之水平狀態後，介於該工作平台(40)與該缺角部位(323)間之空間形狀乃隨之改變，造成該集塵室(52)上方開口與該工作台(40)間之空隙擴大，為避免鋸屑噴出，係可在釋放各該定位栓(538)後，將該延伸體(532)向上移動來填補空隙後，再旋緊各該定位栓(538)進行對該延伸體(532)與該活動側體(531)之定位，其中，當該延伸體(532)與該活動側體(531)在失去各該定位栓(538)之鎖定拘束，並擬進行上下移動之調整作業時，為確保其穩定移動並避免偏移，係將一輔助導栓(539)固定於該箱蓋(322)上，並使一端滑設於該調整孔(537)中，以與各該定位栓(538)對該活動側體(531)及該延伸體(532)形成三點支撐，以確保其移動之穩定與方向之正確性。Furthermore, as shown in Figures 7 and 8, when the workbench (40) changes its level state through conventional technology in response to the needs of working conditions, it is between the workbench (40) and the missing corner The shape of the space between the parts (323) changes accordingly, causing the gap between the upper opening of the dust collection chamber (52) and the workbench (40) to expand. ), move the extension body (532) upward to fill the gap, and then tighten the positioning bolts (538) to locate the extension body (532) and the movable side body (531), wherein, when the When the extension body (532) and the movable side body (531) lose the locking restraint of the positioning bolts (538) and plan to move up and down, in order to ensure their stable movement and avoid deviation, an auxiliary The guide bolt (539) is fixed on the box cover (322), and one end is slidably arranged in the adjustment hole (537) to interact with the positioning bolts (538) to the movable side body (531) and the extension body. (532) Three-point support is formed to ensure the stability of its movement and the correctness of its direction.
併請參閱圖9所示，該導引部(54)具有一孔狀之通道(541)，係貫設於該固定側體之第一板(5121)上地與該集塵室(52)連通，一連接管(542)則同軸於該通道(541)地以一端固設於該固定側體之第一板(5121)外側上，以供作為與外部之負壓源空間進行管路連接之結合構造。Please also refer to Figure 9, the guide portion (54) has a hole-shaped channel (541), which is arranged on the first plate (5121) of the fixed side body and the dust collection chamber (52) Connected, a connecting pipe (542) is coaxially with the channel (541) and fixed on the outside of the first plate (5121) of the fixed side body with one end for pipe connection with the external negative pressure source space Combined structure.
藉由上述構件之組成，在帶鋸機以該鋸帶(20)對於置放在該工作平台上之待加工物件進行鋸切時，隨同鋸帶(20)或自身重量之作用掉落至該集塵室(52)中之鋸屑，係在被收集之同時，可以經由與外部負壓空間連通之作用，使得鋸屑在進入該集塵室(52)後旋即經由該導引部(54)被抽離至外部，而可避免鋸屑之四散，有效地降低對於工作環境所產生之負面影響，以達成本發明之主要目的。With the composition of the above components, when the band saw machine uses the saw band (20) to cut the object to be processed placed on the working platform, it will fall to the The sawdust in the dust collection chamber (52), while being collected, can be communicated with the external negative pressure space, so that the sawdust enters the dust collection chamber (52) and is immediately passed through the guide part (54). Withdrawing to the outside, it can avoid the scattering of sawdust, effectively reduce the negative impact on the working environment, so as to achieve the main purpose of the invention.
除上述之主要功效以外，透過該延伸體(533)之移動，即可因應集塵室(52)上方入口處之空間變化，確保對於鋸屑之收集功效，並令該延伸體(533)係位於鋸帶(20)之齒尖方向上，以提供阻擋鋸屑飛出之遮擋功效。In addition to the main functions mentioned above, the movement of the extension body (533) can respond to the spatial change at the entrance of the dust collection chamber (52), ensure the collection of sawdust, and make the extension body (533) be located In the direction of the tooth tip of the saw band (20), a shielding effect is provided to prevent the sawdust from flying out.
另外，該墊片(515)係以如木片等不致對於鋸齒產生損壞之材料為主，並進一步使該第二缺口(516)之縫寬小於該第一缺口(514)之縫寬，一則可避免鋸帶與該固定側體(512)間之干涉，另則可減少鋸屑由細縫中掉出該集塵室(52)外，以免有害於該集塵單元(50)之集塵效果。In addition, the gasket (515) is mainly made of materials that will not damage the saw teeth, such as wood chips, and further make the slit width of the second notch (516) smaller than the slit width of the first notch (514). The interference between the saw band and the fixed side body (512) is avoided, and the sawdust can be reduced from falling out of the dust collection chamber (52) through the slits, so as not to be harmful to the dust collection effect of the dust collection unit (50).
