[0002] In the gluing industry, in order to enhance the viscosity of the glue, two glues A and B are usually mixed in proportion. In the process of mixing the two glues, a two-component fluid supply device is required.

[0003] However, after searching and combining it with actual glue supply experience, we found that high-flow two-component glue coating still has some common defects and shortcomings in the current glue coating industry: excessive glue supply pressure can easily lead to glue leakage, which affects the stability and precision of glue supply. Therefore, there is an urgent need to improve the existing technical defects. After research and development, our company provides a two-component precision quantitative fluid supply device with a stop valve. Utility Model Content

[0026] like Figure 1-5 As shown, the utility model has a two-component precision quantitative fluid supply device with a stop valve, which includes a mounting plate 1, a screw pump 2 and a pressure sensor 5. The screw pump 2 is fixedly installed symmetrically on the left and right sides in front of the top of the mounting plate 1, and a glue storage box 4 is fixedly installed on the bottom end of the screw pump 2. The pressure sensors 5 are fixedly installed on the left and right outer walls of the glue storage box 4. The upper glue outlet pipe 6 is threadedly installed in the middle position of the bottom end of the glue storage box 4. A connecting plate 7 is fixedly installed on the outer wall in front of the bottom of the mounting plate 1. A glue outlet assembly 8 is fixedly provided at the bottom of the connecting plate 7, and a stop valve assembly 9 is installed on the inner side of the glue outlet assembly 8.

[0027] On the basis of the above structure, the screw pump 2 and the pressure sensor 5 are both arranged symmetrically about the mounting plate 1 , and a glue inlet 3 is provided on the outer wall in front of the bottom end of the left and right screw pumps 2 .

[0028] In this embodiment, two left and right screw pumps 2 and corresponding glue inlets 3 are used to facilitate the simultaneous pumping and supply of two glue fluids.

[0029] On the basis of the above structure, the glue outlet assembly 8 includes an installation box 81, a box cover 82, a lower glue outlet pipe 83, a threaded rod 84 and a butterfly nut 85. The front end of the installation box 81 is rotatably connected to the box cover 82, and a groove structure is provided at the middle position of the right end of the box cover 82. The bottom front end of the installation box 81 is fixedly connected to the lower glue outlet pipe 83 by bolts, and the middle part of the right side of the installation box 81 is rotatably connected to the threaded rod 84, and the outer threaded sleeve of the threaded rod 84 is provided with a butterfly nut 85.

[0030] Based on the above structure, the bottom end of the connecting plate 7 is fixedly connected to the mounting box 81 by bolts, the diameter length of the threaded rod 84 is equal to the width of the groove structure in the middle of the right end of the box cover 82, and the threaded rod 84 and the groove structure in the middle of the right end of the box cover 82 are on the same horizontal plane.

[0031] In this embodiment, the rotatable box cover 82 facilitates the assembly and disassembly of the lower rubber hose 83 , and the threaded rod 84 and the butterfly nut 85 facilitate the stable positioning of the box cover 82 in the closed state.

[0032] Based on the above structure, the stop valve assembly 9 includes a pneumatic rotary cylinder 91, a stop tube 92 and a glue flow channel 93. The pneumatic rotary cylinder 91 is fixedly installed on the inner side of one end of the mounting box 81 close to the connecting plate 7. The output shaft of the pneumatic rotary cylinder 91 is fixedly connected to the stop tube 92. A through glue flow channel 93 is opened inside the stop tube 92.

[0033] Based on the above structure, the cut-off pipe 92 is located between the upper rubber outlet pipe 6 and the lower rubber outlet pipe 83 , and the ends of the upper rubber outlet pipe 6 and the lower rubber outlet pipe 83 close to each other are both slidably sealed with the cut-off pipe 92 .

[0034] On the basis of the above structure, the center lines of the upper glue outlet pipe 6 and the lower glue outlet pipe 83 coincide with each other, and the inner diameter lengths of both are equal to the inner diameter length of the glue flow channel 93 .

[0035] In this embodiment, the pneumatic rotary cylinder 91 is used to control the cut-off tube 92 to rotate 90°, so that the glue flow channel 93 is in a horizontal state. The solid part of the outer wall of the cut-off tube 92 can be used to resist and seal the bottom glue outlet of the upper glue pipe 6, which can control the stable cut-off of the glue fluid and prevent the glue fluid from continuing to flow out and leak due to pressure after closing the glue, thereby avoiding production accidents and fluid waste.

[0036] The working principle of this utility model is as follows:

[0037] When in use, the fluid supply device is first installed at a designated position, and the delivery pipes of the two glues are fixedly connected to the glue inlets 3 of the two screw pumps 2 respectively. When supplying glue, the two glues can be sucked in by the two screw pumps 2 and discharged through the glue storage box 4, the upper glue outlet pipe 6, the cut-off pipe 92 and the lower glue outlet pipe 83. During the glue fluid supply process, the pressure sensors 5 fixedly installed on the outer walls of the left and right sides of the glue storage box 4 can be used to monitor the glue supply pressure in real time;

[0038] When the glue supply needs to be paused, the pneumatic rotary cylinder 91 can be used to control the cut-off pipe 92 to rotate 90 degrees, so that the glue flow channel 93 is as shown in FIG. Figure 5 , and staggered with the upper and lower glue outlet pipes 6 and 83, the solid portion of the outer wall of the cut-off pipe 92 can be used to seal the bottom glue outlet of the upper glue outlet pipe 6, thereby controlling the stable cutoff of the glue fluid and preventing the glue fluid from continuing to flow out and leaking due to pressure after closing the glue, thereby avoiding production accidents and waste of glue fluid;

[0039] The box cover 82 can be rotated to open, which is convenient for installation, removal and replacement of the lower rubber hose 83. When closing the box cover 82, the threaded rod 84 can be rotated to be located in the groove structure provided in the middle of the right end of the box cover 82. Then, the butterfly nut 85 can be manually screwed to move it along the threaded rod 84 until it contacts the outer wall of the box cover 82, so as to facilitate the stable positioning of the box cover 82.

[0040] It should be noted that this application is mainly aimed at the problem in the prior art that glue leakage is prone to occur due to pressure when the glue supply fluid is shut down, and makes corresponding technical improvements. The screw pump 2, glue storage box 4, pressure sensor 5, etc. all use existing products, and their specific structures and working principles are all existing mature technologies. They are not the main innovation direction of this case, so they will not be described in detail.

[0041] The above are only preferred specific embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any equivalent changes, modifications, substitutions and variations made by technicians in this technical field based on the concept of the present invention through logical analysis, reasoning or limited experiments on the basis of existing technologies should be within the scope of protection determined by the claims.
