Description
技术领域technical field
本发明属于工业上料装置领域，尤其涉及一种液体定量上料装置。The invention belongs to the field of industrial feeding devices, in particular to a liquid quantitative feeding device.
背景技术Background technique
目前工业原料的上料操作一部分还是由人工完成，另一部分在上料装置中加入了重量传感器或是计量筒，人工上料存在不能定量的缺点，而重量传感器或者计量筒在使用时，还是需要上料一次就计量一次，上料效率太低。另外，当重量传感器或是计量筒在使用过程中，重量传感器或是计量筒提示达到指定质量时，停止进料，因液体具备流动性，当液体原料在整个生产工序中连续运动会产生一定压力，可能造成实际称量的液体量偏小，除此之外也会存在停止进料后，进料口剩余的尾料还是进入到计量筒内，造成实际液体量偏大。重量传感器和计量筒也不利于后期维护。At present, part of the feeding operation of industrial raw materials is still done manually, and the other part adds a weight sensor or a measuring cylinder to the feeding device. Manual feeding has the disadvantage that it cannot be quantified, and the weight sensor or measuring cylinder still needs The feeding efficiency is too low if the feeding is done once. In addition, when the weight sensor or the measuring cylinder is in use, when the weight sensor or the measuring cylinder prompts that the specified quality is reached, the feeding is stopped. Because the liquid has fluidity, when the liquid raw material moves continuously in the entire production process, a certain pressure will be generated. It may cause the actual amount of liquid to be weighed to be too small. In addition, after the feeding is stopped, the remaining tailings at the feed port will still enter the metering cylinder, resulting in a relatively large actual liquid amount. Weight sensors and measuring cylinders are also not conducive to later maintenance.

工作原理：一种液体定量上料装置，设置定量腔，在定量腔内设有可来回直线运动的推进器，再通过设置左右两组磁铁限位环来分别限定推进器运动至最左端和最右端的位置，且磁铁限位环可对推进器产生吸力。初始时，推进器位于定量腔的最右端，定量腔右侧磁铁限位环吸附住推进器，盛料区的液体通过进液管流入并充满定量腔右边的流体区内，此时推进器上的通孔完全连通定量腔内的左右两个流体区，因此上料的液体通过通孔从右侧流体区流入并充满整个左侧流体区内，当需要加料时，驱动电机驱动活塞从中空结构的最右侧位置移动至最左侧位置，此时活塞刚好完全密封住通孔，然后开启控制阀同时继续驱动活塞移动，当推力大于右侧磁铁限位环对推进器的吸附力时，推进器脱离右侧磁铁限位环并向左侧移动，移动过程中活塞左部分的液体从出液管排出，当推进器移动到定量腔内的左侧磁铁限位环时，定量腔左侧组磁铁限位环吸附住推进器，此时推进器移动到终点，完成一次定量上料的过程，然后关闭控制阀，驱动电机驱动活塞在中空结构内回退，此时露出通孔，推进器右侧的液体会通过通孔进入左侧，然后驱动电机继续驱动活塞，当拉力大于左侧磁铁限位环对推进器的吸附力时，推进器脱离左侧磁铁限位环并向右侧移动，在移动过程中推进器右侧的液体会通过通孔连续进入左侧，推进器向右移动直至右侧磁铁限位环被吸附住，即完成下一次定量上料的准备工作，这样重复驱动推动器左右往复运动，每次推进器从最右端运动到最左端时，即完成一次定量加料操作，加料的液体容量就是推进器位于最左端和最右端位置时中间的容量，由此实现了定量加料操作，不会产生误差，只需对驱动电机进行定时旋转换向设置，即可实现自动化持续定量加料操作，显著提高了生产效率，后期维护也方便低廉。Working principle: a liquid quantitative feeding device, with a quantitative cavity, a propeller that can move back and forth linearly in the quantitative cavity, and then by setting two sets of magnet limit rings on the left and right to limit the movement of the propeller to the leftmost and extreme The position at the right end, and the magnetic limit ring can generate suction to the propeller. Initially, the propeller is located at the rightmost end of the dosing chamber, and the magnetic limit ring on the right side of the dosing chamber absorbs the propeller. The through hole in the dosing cavity completely communicates with the left and right fluid areas in the quantitative chamber, so the liquid to be fed flows into and fills the entire left fluid area through the through hole from the right fluid area. When feeding is required, the drive motor drives the piston from the hollow structure. Move the rightmost position to the leftmost position. At this time, the piston just completely seals the through hole. Then open the control valve and continue to drive the piston to move. When the thrust is greater than the adsorption force of the right magnet limit ring to the propeller, push The pusher breaks away from the right magnet limit ring and moves to the left. During the movement, the liquid in the left part of the piston is discharged from the liquid outlet pipe. When the propeller moves to the left magnet limit ring in the quantitative cavity, the left group of the quantitative cavity The magnet limit ring absorbs the propeller. At this time, the propeller moves to the end point to complete a quantitative feeding process. Then the control valve is closed, and the motor drives the piston to retreat in the hollow structure. At this time, the through hole is exposed, and the right side of the propeller The liquid on the side will enter the left side through the through hole, and then drive the motor to continue to drive the piston. When the pulling force is greater than the adsorption force of the left magnet limit ring on the propeller, the propeller will break away from the left magnet limit ring and move to the right. During the moving process, the liquid on the right side of the propeller will continuously enter the left side through the through hole, and the propeller moves to the right until the magnet limit ring on the right side is absorbed, that is, the preparation for the next quantitative feeding is completed, and the drive is repeated in this way The propeller reciprocates left and right, and each time the propeller moves from the rightmost end to the leftmost end, a quantitative feeding operation is completed. The liquid capacity for feeding is the middle capacity when the propeller is at the leftmost and rightmost positions, thus realizing quantitative feeding The operation will not cause errors, and only need to set the timing rotation and reversing of the drive motor to realize the automatic continuous quantitative feeding operation, which significantly improves the production efficiency, and the later maintenance is also convenient and low-cost.

When the drive device is powered on, the drive motor starts to drive the screw to rotate, and at the same time, the fixed plate starts to move parallel to the left along the guide rail. The fixed plate gives the push rod a leftward thrust, and the push rod will push the piston to continue to move to the left until the pusher moves to a certain amount. At the leftmost position of the cavity, when the quantitative feeding is completed, close the control valve, at this time, the drive motor drives the screw to rotate in the opposite direction, and the fixed plate starts to move to the right. The fixed plate gives the pulling force to the right of the push rod, and the push rod will push the piston continuously. Move to the right until the propeller moves to the rightmost position of the quantitative cavity, that is, the preparation for the next quantitative feeding is completed.
作为所述的一种液体定量上料装置的优选结构，所述控制阀5为单向阀。如图1所示，固定所述丝杆14左端的轴承座固定在所述定量腔3的右侧侧壁上，所述定量腔的右侧侧壁外侧设有凸起部17，所述固定板15沿所述导轨16运动至最左端时与所述凸起部17抵触。这样当固定板运动至最左端时，固定板一部分会抵住轴承座，另一部分悬空，凸起部的设置有利于固定板保持平衡。As a preferred structure of the liquid quantitative feeding device, the control valve 5 is a one-way valve. As shown in Figure 1, the bearing seat that fixes the left end of the screw rod 14 is fixed on the right side wall of the quantitative chamber 3, and the outside of the right side wall of the quantitative chamber is provided with a raised portion 17, and the fixed When the plate 15 moves to the leftmost end along the guide rail 16 , it interferes with the protrusion 17 . In this way, when the fixed plate moves to the leftmost end, a part of the fixed plate will be against the bearing seat, and the other part will be suspended in the air, and the setting of the raised portion is conducive to the balance of the fixed plate.
在本发明实施例中，通过设置左右两组磁铁限位环来分别限定推进器运动至最左端和最右端的位置，当需要加料时，电机驱动推进器从最右端运动到最左端时，即完成一次定量加料操作，加料的液体容量就是推进器位于最左端和最右端位置时中间的容量，这样就实现了定量加料操作，不会产生误差，只需对驱动电机进行定时旋转换向设置，即可实现自动持续定量加料操作，显著提高了生产效率，同时每次加料的容量也容易保持一致，避免了如重量传感器或是计量筒般存在的加料量误差，相比重量传感器或是计量筒，整个装置后期维护也方便低廉。In the embodiment of the present invention, the left and right two sets of magnet limit rings are used to limit the position of the pusher to the leftmost and rightmost respectively. When feeding is required, the motor drives the pusher to move from the rightmost to the leftmost, that is To complete a quantitative feeding operation, the liquid capacity of the feeding is the middle capacity when the propeller is at the leftmost and rightmost positions. In this way, the quantitative feeding operation is realized without error. It is only necessary to set the timing rotation and reversing of the drive motor. It can realize the automatic continuous quantitative feeding operation, which significantly improves the production efficiency. At the same time, the capacity of each feeding is easy to keep consistent, avoiding the feeding amount errors such as weight sensors or measuring cylinders. Compared with weight sensors or measuring cylinders , and the maintenance of the whole device is also convenient and cheap.
