Detailed Implementation Manner

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Referring to Figure 1 - Figure 2 , an embodiment provided by the present utility model: a heat-conducting paste dispensing valve with precise flow regulation, comprising a first housing 1. The rear end of the top of the first housing 1 is rotatably connected to a second housing 2. By rotating the second housing 2 at the rear end of the first housing 1, the first housing 1 can be opened for cleaning. The left end of the first housing 1 is fixedly connected to a glue outlet nozzle 3, and glue is discharged through the glue outlet nozzle 3. A storage box 4 is fixedly connected to the adjacent side of the second housing 2 and the glue outlet nozzle 3 respectively. A plurality of threaded grooves 5 are opened on the adjacent side of the two storage boxes 4. A glue discharging assembly is fixedly connected to the rear end of one of the storage boxes 4. The glue discharging assembly includes a cylinder 6. The front end of the cylinder 6 is fixedly connected to the rear end of one of the storage boxes 4, so that the cylinder 6 is supported. The driving end of the cylinder 6 is fixedly connected to a moving plate 7. When the cylinder 6 is started, the moving plate 7 can be driven to move. The outer part of the moving plate 7 is slidably connected to the inner walls of the first housing 1 and the second housing 2 respectively, so that the moving plate 7 can move stably.

[0025] A support rod 8 is fixedly connected to the middle of the left end of the moving plate 7. When the moving plate 7 moves, the support rod 8 can be driven to move. The left end of the support rod 8 is rotatably connected to a spiral block 9. When the support rod 8 moves, the spiral block 9 can be pushed to move. The outer part of the spiral block 9 is movably connected to the inner walls of the two threaded grooves 5 respectively. By pushing the spiral block 9 with the support rod 8, the spiral block 9 moves on the inner wall of the threaded groove 5, so that the spiral block 9 rotates while moving. A push rod 10 is fixedly connected to the front side of the left end of the moving plate 7. The left end of the push rod 10 is fixedly connected to a pressing block 11. The pressing block 11 can be pushed to move through the push rod 10. A buffer box 12 is fixedly connected to the front end of the top of the first housing 1. The buffer box 12 can be stabilized by the first housing 1. The outer part of the pressing block 11 is slidably connected to the inner wall of the buffer box 12, so that the pressing block 11 is restricted. A first spring 13 is arranged inside the buffer box 12. One side of the first spring 13 is fixedly connected to one inner wall of the buffer box 12, and the other end of the first spring 13 is fixedly connected to one side of the pressing block 11. When the pressing block 11 moves, the first spring 13 can be compressed and deformed to generate elastic potential energy.

[0026] Refer to Figure 1 、 Figure 3 and Figure 4, a groove is formed inside the second housing 2, and a plurality of second springs 14 are arranged inside the groove. A limiting block 15 is slidably connected to the inner wall of the groove. The limiting block 15 is restricted by the groove. One end of the second spring 14 is fixedly connected to one inner wall of the groove, and the other end of the second spring 14 is fixedly connected to one side of the limiting block 15. The second spring 14 can be compressed under the movement of the limiting block 15, so that the second spring 14 deforms to generate elastic potential energy. A sealing block 16 is fixedly connected to the bottom of the limiting block 15, and the bottom of the sealing block 16 fits against the top of the first housing 1, so that the sealing block 16 can achieve a sealing effect. The outside of the sealing block 16 is slidably connected to the bottom of the second housing 2. An extension block 17 is fixedly connected to the front end of the bottom of the second housing 2, and the second housing 2 can be restricted through the extension block 17.

[0027] A sliding rod 18 is slidably connected to the front end of the first housing 1. The rotation of the second housing 2 can be controlled under the sliding of the sliding rod 18. A third spring 19 is sleeved on the outside of the sliding rod 18. A reset block 20 is fixedly connected to the outside of the sliding rod 18. The reset block 20 can be driven to move under the movement of the sliding rod 18. The outside of the reset block 20 is slidably connected to the inner wall of the first housing 1, so that the movement of the reset block 20 is stable. One end of the third spring 19 is fixedly connected to one side of the reset block 20, and the other end of the third spring 19 is fixedly connected to one inner wall of the first housing 1. The third spring 19 can be compressed under the movement of the reset block 20, so that the third spring 19 deforms to generate elastic potential energy. The outside of the sliding rod 18 is engaged with the through hole of the extension block 17, so that the extension block 17 is stabilized and the second housing 2 is stabilized. A connection slot hole 21 is arranged at the top of the second housing 2, and external pipelines are connected through the connection slot hole 21 to convey materials.

[0028] Working principle: When in use, an external pipeline is connected through the connecting slot 21 to transport the colloid. When dispensing glue is required, the cylinder 6 is started. Under the actuation of the cylinder 6, the moving plate 7 can be driven to move. Under the movement of the moving plate 7, the support rod 8 can be driven to move. Through the movement of the support rod 8, the spiral block 9 can be pushed to move. At this time, the spiral block 9 moves inside the inner wall of the storage box 4 to push the colloid inside the storage box 4. At this time, the colloid is output from the glue outlet nozzle 3. The amount of glue dispensing can be controlled by the cylinder 6. When the moving plate 7 moves, the push rod 10 will be driven to push the extrusion block 11, so that the first spring 13 is extruded, and thus the first spring 13 deforms to generate elastic potential energy for buffering. When it is necessary to clean the inside of the valve body, by pulling the sliding rod 18, at this time, the pulling of the sliding rod 18 can drive the reset block 20 to move, so that the reset block 20 exits the through hole of the extension block 17. At this time, the extension block 17 can be taken out from the top of the housing 1, so that the housing 2 can rotate smoothly, thereby cleaning the inside of the valve body. During installation, by rotating the housing 2, the sealing block 16 abuts against the top of the housing 1. At this time, the sealing block 16 will push the limiting block 15, so that the limiting block 15 extrudes the second spring 14. Under the condition that the second spring 14 is extruded, the sealing block 16 can abut against the top of the housing 1. Then, by the sliding rod 18 clamping the inner wall of the extension block 17, the sealing effect can be achieved to prevent the colloid from leaking.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
