                3.2 SYT-4型雙組份打膠機氣動工作原理
                3.2 pneumatic working principle of syt-4 two-component glue applicator
                SYT-4型雙組份打膠機以壓縮空氣為動力。壓縮空氣在這里有兩個作用:一是推動A、B泵的氣動馬達運動和調比機構動作(由A泵帶動);二是控制A、B組份泵的升降、進(脫)桶。
                Syt-4 two-component gluer is powered by compressed air. Compressed air has two functions here: one is to drive the pneumatic motor of pumps a and B and the ratio adjustment mechanism (driven by pump a); The second is to control the lifting and unloading of component A and B pumps.
                整機設有一個總開關(G3/4銅球閥);A、B泵各自有一個開關;A、B泵升降機由各自的手動轉閥(即控制箱面板上升降閥)控制,有“升”、“停”、“降”三個工位;壓盤上有一個手動進氣閥和一個放氣開關(G1/4銅球閥)。
                The whole machine is equipped with a main switch (G3 / 4 copper ball valve); A. Each pump B has a switch; A. Pump B elevator is controlled by respective manual rotary valve (i.e. the rising and falling valve on the control box panel), which has three stations of "rising", "stopping" and "falling"; There is a manual air inlet valve and a vent switch (G1 / 4 copper ball valve) on the pressure plate.
                3.3A泵、B泵工作原理雙組份打膠機
                3. Working principle of 3A pump and B pump (see Fig. 4 and Fig. 5)
                A泵和B泵均為雙作用式氣動液壓增壓泵。A泵為機械換向機構,工作原理為:氣動馬達從頂部進入壓縮空氣后,氣缸活塞移動到氣缸上或下接近端部時,與氣活塞連接的活塞桿壓縮換向彈簧,彈簧積蓄能量,活塞繼續前行,到一定位置,換向機構在彈簧的作用下,瞬時推動配氣換向裝置換向,從而使氣動馬達氣缸中的活塞作穩定連續的往復運動。氣缸活塞的力,作用于液壓泵中的柱塞。由于氣缸活塞的面積比液壓泵中的面積大,因而使吸入的膠增壓,增壓后的膠通過泵座的接頭輸出。


                Both pump a and pump B are double acting pneumatic hydraulic booster pumps. Pump a is a mechanical reversing mechanism. Its working principle is as follows: after the pneumatic motor enters compressed air from the top, when the cylinder piston moves up or down close to the end of the cylinder, the piston rod connected with the gas piston compresses the reversing spring, the spring accumulates energy, the piston continues to move forward to a certain position, and the reversing mechanism instantaneously pushes the reversing device of gas distribution under the action of the spring, Thus, the piston in the pneumatic motor cylinder makes a stable and continuous reciprocating motion. The force of the cylinder piston acts on the plunger in the hydraulic pump. Since the area of the cylinder piston is larger than that of the hydraulic pump, the inhaled rubber is pressurized, and the pressurized rubber is output through the joint of the pump base.
                B泵為差壓式機械換向機構,工作原理為:氣動馬達從頂部進入壓縮空氣,如進入氣缸下腔,則上腔與大氣連通,壓縮空氣作用于活塞的力(為氣缸面積的一半,因為要除去占氣缸一半面積的柱塞桿的面積),使活塞帶動液壓泵中的活塞桿及柱塞向上運動,當氣缸活塞移動到氣缸上接近端部時,與氣活塞連接的柱塞桿壓縮換向彈簧,彈簧積蓄能量,活塞繼續前行,到一定位置,換向機構在彈簧的作用下,瞬時推動配氣換向裝置換向,從而使壓縮空氣同時進入氣缸的上腔和下腔。
                Pump B is a differential pressure mechanical reversing mechanism. Its working principle is: the pneumatic motor enters the compressed air from the top. If it enters the lower chamber of the cylinder, the upper chamber is connected with the atmosphere. The force of the compressed air acting on the piston (half of the cylinder area, because the area of the plunger rod accounting for half of the cylinder area should be removed) causes the piston to drive the piston rod and plunger in the hydraulic pump upward, When the cylinder piston moves to the cylinder near the end, the plunger rod connected with the gas piston compresses the reversing spring, the spring accumulates energy, and the piston continues to move forward to a certain position. Under the action of the spring, the reversing mechanism instantaneously promotes the reversing of the gas distribution reversing device, so that the compressed air enters the upper and lower cavities of the cylinder at the same time.
                由于上腔有效面積是下腔有效面積的兩倍,因而壓縮空氣作用于活塞上端的力大于下端,則活塞帶動液壓泵中的活塞桿及柱塞向下運動,氣缸活塞移動到氣缸下接近端部時,與氣活塞連接的柱塞桿壓縮換向彈簧,彈簧積蓄能量,活塞繼續前行,到一定位置,換向機構在彈簧的作用下,瞬時推動配氣換向裝置換向。這樣,實現了活塞的往復運動。
                Since the effective area of the upper chamber is twice that of the lower chamber, the force of compressed air on the upper end of the piston is greater than that on the lower end, the piston drives the piston rod and plunger in the hydraulic pump to move downward. When the cylinder piston moves to the lower end of the cylinder, the plunger rod connected with the gas piston compresses the reversing spring, the spring accumulates energy, and the piston continues to move forward to a certain position, Under the action of the spring, the reversing mechanism instantaneously pushes the valve reversing device to reverse. In this way, the reciprocating motion of the piston is realized.
                B泵的作用是向比例泵輸送向上吸入時所需要的膠。因此,比例泵吸入時,B泵則運動;比例泵壓出時,B泵則不能運動。所以,雙組份打膠機正常工作時,則B泵為間斷式運動(不能連續運動)。
                The function of pump B is to deliver the glue required for upward suction to the proportional pump. Therefore, when the proportional pump sucks in, pump B moves; When the proportional pump is pressed out, pump B cannot move. Therefore, when the two-component glue applicator works normally, pump B moves intermittently (not continuously).
