請參閱第5圖所示,當首次入料或發現原料中有氣體時,該電動缸30會驅動該推桿22上昇到使該推塞220高於該排氣溢料口27的位置,如此當該入料裝置由該入料口26送入液體狀的原料,該原料便會開啟該單向入料逆止閥29而使原料進入該筒身21之中,入料壓力會使筒身21中的空氣由該排氣溢料口27排出,且因不足以開啟該單向出料逆止閥28,而會使注入的原料只能朝上充填滿該筒身21,而當該原料充滿該筒身21的內部時,原料裏的空氣會被由該排氣溢料口27擠出以避免空氣累積影響出料穩定(空氣可壓縮),而且該筒身21中多餘的原料亦可由該排氣溢料口27導出。 Referring to FIG. 5, when there is gas in the first feed or found in the raw material, the electric cylinder 30 drives the push rod 22 to rise to a position where the push plug 220 is higher than the exhaust overflow port 27, When the feeding device feeds the liquid material from the inlet port 26, the material opens the one-way feeding check valve 29 to allow the raw material to enter the barrel 21, and the feeding pressure causes the barrel The air in 21 is discharged from the exhaust overflow port 27, and because it is insufficient to open the one-way discharge check valve 28, the injected raw material can only be filled upwardly to fill the barrel 21, and when the raw material When the inside of the barrel 21 is filled, the air in the raw material is extruded from the exhaust overflow port 27 to prevent the air accumulation from affecting the discharge stability (air compressibility), and the excess material in the barrel 21 can also be The exhaust overflow port 27 is led out.

請參閱第6圖所示,當該筒身21中充滿原料時,該電動缸30會驅動該推桿22下降,該推塞220便會將筒身21之中的原料向下推擠,此時該單向入料逆止閥29會被筒身21內部的原料壓力關閉而無法逆流出入料口26,同時該筒身21之中的原料壓力會開啟該單向出料逆止閥28,而使原料流入該針頭23,再注射至所需之位置。而當注射完後,電動缸30會驅動該推桿22上昇到使該推塞220低於該排氣溢料口27的位置,同時該入料裝置會由該入料口26送入液體狀的原料至填滿該筒身21之中,然後停止入 料,再使該電動缸30驅動該推桿22下降以將筒身21之中的原料向下推擠,如此重覆上述使該推桿22上昇到使該推塞220低於該排氣溢料口27的位置且同時入料及停止入料並使該推桿22下降之動作便可達到連續自動注射液體及精準控制注射量之目的。而且,當在上述重覆注射動作中當發現原料內有氣體時或是欲對其進行清潔作業時,才會再使該推桿22上昇到使該推塞220高於該排氣溢料口27的位置,以擠出原料中的空氣或是利用該排氣溢料口27做為清潔時之迴流循環孔以便於清潔作業。 Referring to FIG. 6, when the barrel 21 is filled with raw materials, the electric cylinder 30 drives the push rod 22 to descend, and the push plug 220 pushes the material in the barrel 21 downward. When the one-way feed check valve 29 is closed by the material pressure inside the barrel 21, it cannot be reversely flowed out of the inlet port 26, and the material pressure in the barrel 21 opens the one-way discharge check valve 28, The raw material is allowed to flow into the needle 23 and is injected to the desired position. When the injection is completed, the electric cylinder 30 drives the push rod 22 to rise to a position where the push plug 220 is lower than the exhaust overflow port 27, and the feeding device is fed into the liquid state from the inlet port 26. Raw material to fill the barrel 21, then stop Then, the electric cylinder 30 is driven to lower the push rod 22 to push the material in the barrel 21 downward, so as to repeat the above, the push rod 22 is raised to make the push plug 220 lower than the exhaust overflow. The position of the material port 27 and the simultaneous feeding and stopping of the feeding and the lowering of the push rod 22 can achieve the purpose of continuously and automatically injecting the liquid and precisely controlling the injection amount. Moreover, when the gas in the raw material is found to be in the above-mentioned repeated injection operation or if the cleaning operation is to be performed, the push rod 22 is raised again to make the push plug 220 higher than the exhaust overflow opening. The position of 27 is to extrude the air in the raw material or use the exhaust overflow port 27 as a recirculation circulation hole for cleaning to facilitate the cleaning operation.
