Guide rod 12 runs through in proper order and supports clamp plate 3 and pump case 13 and with piston 11 fixed connection, spring 14 sets up in pump case 13, and one end and pump case 13 keep away from 16 end butts of sap cavity, the other end and piston 11 butt, positioning mechanism 15 and guide rod 12 sliding connection and fixed connection, with support clamp plate 3 butt and set up in the one side that supports clamp plate 3 and keep away from pump case 13. When the pressing plate 3 moves upward to drive the positioning mechanism 15 to move, because the positioning mechanism 15 is fixedly connected with the guide rod 12 and drives the guide rod 12 and the piston 11 to move upward, the pressure in the liquid chamber 16 is reduced, liquid enters the liquid chamber 16 from the liquid inlet 131, when the pressing plate 3 moves downward, the pressing plate 3 is not driven to move any more, the spring 14 is in a compressed state, the piston 11 moves downward under the action of the elastic force of the spring 14, the pressure of the liquid in the liquid chamber 16 is increased, and therefore the liquid flows out from the liquid outlet 132. It should be noted that, because the positioning mechanism is slidably and fixedly connected with the guide rod 12, so that the positioning mechanism 15 can be fixed at different positions of the guide rod 12, when the pressing plate 3 moves upward to the upper limit position, if the positioning mechanisms 15 of the plurality of pump bodies 1 are fixed at different lengths of the guide rod 12, the positions of the pistons 11 of the plurality of pump bodies 1 are also inconsistent, and the position of the piston 11 in the liquid cavity 16 can be adjusted by adjusting the position of the positioning mechanism 15, thereby achieving the purpose of controlling the amount of liquid to be sucked, and in addition, when the pressing plate 3 moves to the lower limit position, all the pistons 11 in the pump bodies 1 are pressed down to the lowest position, namely, are abutted against the inner wall of the pump shell 13, so that the position of the positioning mechanism 15 can be adjusted to adjust the volume of liquid sucked and extruded by the corresponding pump. As a preferred embodiment, the plurality of pump bodies 1 are arranged side by side, so that the plurality of pump bodies 1 can suck different liquids to avoid the liquid from being mixed and input, and the pressing plate 3 is arranged in parallel with the fixed plate 2, so that the plurality of guide rods 12 can keep consistent speed when the pressing plate 3 drives the plurality of guide rods 12 to move.

The driving unit 4 is arranged between the fixing plate 2 and the pressing plate 3, and two ends of the driving unit are respectively fixedly connected with the fixing plate 2 and the pressing plate 3. As the preferred embodiment, this drive unit 4 is the cylinder, and the cylinder drive is supported clamp plate 3 and is upwards or downward motion, and the cylinder adopts solenoid valve and time relay or PLC control, consequently can realize the periodic dropwise add raw materials, and the control program that adopts PLC control is very simple, adopts the control program among the prior art can, and here is no longer repeated.

As a preferred embodiment, the positioning mechanism 15 includes two nuts, both of which are in threaded connection with the guide rod 12, and when the position of the positioning mechanism 15 relative to the guide rod 12 needs to be adjusted, the two nuts are loosened, the position is adjusted, and finally the two nuts are tightened relatively, so that the positioning mechanism 15 can not move along the guide rod 12 any more.

As a preferred embodiment, the pump housing 1 is transparent and is graduated on the side, so that the volume of liquid which is sucked up and squeezed out of the liquid chamber of the pump housing at a time can be read by the graduation.

Example 2:

referring to fig. 3 and 4, embodiment 2 is substantially the same as embodiment 1 except that:

the positioning mechanism 15 includes a sliding plate 151 and a positioning plate 152, a matching portion 121 is formed on the side surface of the guide rod, a sliding hole 1511 is formed on the sliding plate 151, the sliding hole 1511 is in sliding fit with the matching portion 121, a plurality of positioning grooves 122 are further formed on the side surface of the guide rod 12 along the axial direction, a positioning hole 1521 is formed on the positioning plate 152, a positioning portion 1522 is formed at one end of the positioning plate 152, a sliding groove 1512 is formed on the sliding plate 151, the positioning portion 1522 is in sliding fit with the sliding groove 1512, the end surface of the positioning portion 1522 is abutted against the sliding plate 151, so that the sliding plate 151 and the positioning plate 152 are coaxial and rotatably connected, the sliding plate 151 and the positioning plate 152 cannot relatively move along the axial direction, the positioning plate 152 includes a first position and a second position when rotating relative to the sliding plate 151, when the positioning plate 152 is located at the first position, the positioning portion 2 is abutted against one end of the inner wall of the sliding groove 1512, and the, the positioning plate 152 is separated from the positioning groove 122, and the sliding plate 151 can slide along the guide rod 12. The cross section of the matching portion 121, the sliding hole 1511 and the positioning hole 1521 may be rectangular, triangular, etc., so that the matching portion 121 and the positioning hole 1521 can only slide along the axial direction and cannot rotate along the circumferential direction, and the positioning hole 1521 can slide along the axial direction, and when rotating to the first position, the positioning piece 152 abuts against the positioning groove 122, so that the sliding piece 151 cannot move along the axial direction of the guide rod 12 any more, and the matching portion is preferably rectangular in this embodiment. In a preferred embodiment, the distances from the two ends of the sliding channel 1512 to the center of the positioning plate 152 are equal, and are greater or smaller than the distances from the other positions of the sliding channel 1512 to the center of the positioning plate 152. Therefore, the positioning piece 152 can only be rotated by applying a certain rotational force to the positioning piece 152, and the positioning portion 1522 is pressed against the side wall of the sliding groove 1512 and deformed in the process that the positioning portion 1522 rotates from one end of the sliding groove 1512 to the other end of the sliding groove 1512, until the positioning portion 1522 rotates to the other end of the sliding groove 1512, the positioning portion 1522 is no longer pressed against the sliding groove 1512, and thus deformation is recovered.

Therefore, when the positioning plate 152 is rotated to the first position, the sliding plate 151 cannot move axially along the guide rod 12, when the positioning plate 152 is rotated to the second position, both the sliding plate 151 and the positioning plate 152 can move axially along the guide rod 12, the relative positions of the positioning mechanism 15 and the guide rod 12 can be adjusted, and after the adjustment is completed, the positioning plate 152 is rotated to the first position. The positioning mechanism 15 is therefore simpler and more convenient to use than in embodiment 1.

In conclusion, when the drive unit drives the pressing plate to move to the upper limit position, the pump body sucks liquid, when the liquid needs to be dripped, the drive unit drives the pressing plate to move downwards, the piston moves downwards under the action of the elastic force of the spring, the liquid in the liquid cavity is extruded, and the liquid dripping device is convenient to use.
