DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-9 The utility model provides a technical solution: a liquid material dripping device, comprising a workbench 1, a fixing frame 2 arranged on the workbench 1, a material storage tank 3 fixed on the fixing frame 2 for storing liquid, and a dropper head 5 arranged at intervals at the liquid outlet end of the material storage tank 3, and also comprising:

[0031] The regulating unit 4 is arranged at the discharge end of the storage tank 3 and is used to perform preliminary regulation on the flow rate of the liquid;

[0032] The regulating member 53 is arranged inside the dropper head 5 and is used to further regulate the flow rate of the liquid.

[0033] It should be noted that, during operation, the liquid raw material is added into the storage tank 3 through the pump body, and then the liquid raw material is transported to the dropper head 5 for dripping through the delivery pump, and when the dropper head 5 is dripping, the liquid delivery amount from the storage tank 3 to the inside of the dropper head 5 can be adjusted by the adjustment unit 4, and then the dripping flow rate of the liquid of multiple dropper heads 5 can be adjusted separately by the adjustment member 53, and the dripping flow rate of the dropper head 5 can be controlled one by one according to the working requirements, and can be used to meet multiple dripping flow requirements at the same time. By setting up the device, multiple dropper heads 5 can be set to simultaneously inject liquid into multiple containers, thereby improving the injection efficiency, and by setting the adjustment unit 4 and the adjustment member 53, the dripping flow rate of the dropper head 5 is subjected to multiple restrictions, which can improve the accuracy of the dripping of the dropper head 5, and the adjustment member 53 can meet the control of multiple dripping flow rates, so that the practicality of the entire device is relatively strong.

[0034] In one embodiment, the top of the storage tank 3 is provided with a feed pipe 31 penetrating the storage tank 3, a discharge pipe 32 disposed at the lower part of the storage tank 3 and penetrating the storage tank 3, a mounting pipe 321 disposed at one side of the discharge pipe 32 for mounting the regulating unit 4, and a shunt pipe 33 disposed at the lower end of the discharge pipe 32;

[0035] The shunt pipe 33 is connected to the dripper head 5 via a branch pipe 331 .

[0036] In this design, the pump body adds the liquid raw material into the interior of the storage tank 3 through the feed pipe 31, and then the delivery pump discharges the raw material in the storage tank 3 into the interior of the downpipe 32, and flows from the diversion pipe 33 into the interior of each branch pipe 331, providing the liquid raw material to the interior of the dripper head 5. The flow rate of the liquid to the downpipe 32 can be controlled by the regulating unit 4, and then the liquid supply amount from the diversion pipe 33 to the branch pipe 331 can be controlled.

[0037] In one embodiment, the adjusting unit 4 includes a screw 41 threadedly connected to the mounting tube 321, a turntable 42 arranged on the side of the screw 41 located outside the mounting tube 321, and a sealing block 43 rotatably arranged on the side of the screw 41 located inside the mounting tube 321 for adjusting the discharge amount of the discharge tube 32. The sealing block 43 can be adjustably arranged inside the discharge tube 32.

[0038] By such a design, the turntable 42 is rotated so that the screw 41 drives the sealing block 43 to move toward the inside of the lower material pipe 32, thereby adjusting the discharge gap of the lower material pipe 32, and reducing the gap for the liquid to flow down from the lower material pipe 32, thereby preliminarily adjusting the dripping flow rate of the dripper head 5.

[0039] In one embodiment, the sealing block 43 includes a vertical block and a horizontal block. The length of the vertical block is the same as the diameter of the horizontal block. The vertical block is slidably disposed inside the mounting tube 321 and fits tightly against the inner wall of the discharge tube 32. The horizontal block fits tightly against the inner wall of the mounting tube 321.

[0040] With such a design, when the vertical block of the sealing block 43 is completely inserted into the interior of the feeding tube 32, it is completely fitted with the inner wall of the feeding tube 32, so that the liquid no longer flows into the dropper head 5, and the horizontal block of the sealing block 43 is tightly fitted with the inner wall of the mounting tube 321, and the liquid will not flow from the feeding tube 32 into the interior of the mounting tube 321, and when the vertical block of the sealing block 43 moves toward the interior of the mounting tube 321, the vertical block of the sealing block 43 can be completely retracted into the interior of the mounting tube 321.

[0041] In one embodiment, the dropper head 5 includes a connecting member 51 fixedly disposed on the branch pipe 331 and a liquid outlet 52 fixed at the lower end of the connecting member 51, and the connecting member 51 is connected to the adjusting member 53;

[0042] An inlet end 511 is provided at the connection between the connecting member 51 and the branch pipe 331;

[0043] A sealing opening 512 with a cone-shaped top for preventing liquid leakage is provided in the middle of the connecting piece 51 .

[0044] With such a design, the adjusting member 53 is rotated to change the position of the adjusting member 53 in the connecting member 51, so that the gap between the adjusting member 53 and the sealing port 512 is changed, and the liquid in the branch pipe 331 flows from the inlet end 511 into the sealing port 512, and then flows into the liquid outlet 52, and drips out from the lower end of the liquid outlet 52. The size of the discharge gap of the sealing port 512 can be adjusted by adjusting the installation position of the adjusting member 53 in the sealing port 512, thereby controlling the dripping flow rate of the liquid at the liquid outlet 52.

[0045] In one embodiment, the adjusting member 53 includes a threaded section 533 threadedly connected to the upper part of the connecting member 51, a rotating block 531 arranged at the upper end of the threaded section 533, and a sealing member 532 arranged at the lower end of the threaded section 533, and the bottom end of the sealing member 532 is arranged corresponding to the shape of the sealing port 512.

[0046] With this design, by rotating the rotating block 531, the threaded section 533 engages with the connecting piece 51, thereby changing the position of the sealing piece 532 in the sealing opening 512, so that the gap between the sealing piece 532 and the sealing opening 512 changes, thereby further adjusting the dripping flow rate of the liquid, and improving the dripping accuracy of the dropper head 5.
