Technical Field

[0001] This utility model relates to the field of gear pump technology, specifically to an anti-jamming partition gear pump. Background Technology

[0002] A gear pump is a rotary pump that relies on the change and movement of the working volume formed between the pump cylinder and the meshing gears to transport or pressurize liquids.

[0017] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Please see Figures 1-6 This utility model provides a technical solution: an anti-jamming diaphragm gear pump, which includes: a metal plate 1, a metal plate 2, and a metal plate 3. The upper end of the metal plate 1 is provided with a metal part 16. When the output rod 13 is connected to the motor, the output rod 13 can be limited by the metal part 16. The lower end of the metal part 16 is fixedly connected with a sealing ring 15, which is in close contact with the metal plate 1. The surface of the metal plate 2 is provided with a glue outlet 9 and a glue inlet 8. The glue material can enter through the glue inlet 8 and then be discharged through the glue outlet 9.

[0019] Metal plate 2 has a through-hole on its surface. Gear 6 and gear 7 are rotatably connected inside the hole. Gear 6 and gear 7 mesh with each other, and the rotation of gear 6 and gear 7 allows for the metered discharge of adhesive material. The thickness of gear 6 and gear 7 is the same as that of metal plate 2, which facilitates overall installation and prevents material leakage from either side of gear 6 or gear 7. The lower side of metal plate 1 contacts diaphragm 4. Diaphragms 4 and 5 are both made of Teflon to improve lubrication and facilitate the rotation of gear 6 and gear 7, while preventing material from adhering to their surfaces. The other side of diaphragm 4 contacts one side of metal plate 2, the other side of metal plate 2 contacts one side of diaphragm 5, and the other side of diaphragm 5 contacts metal plate 3. Metal plates 1 and 3 are identical in shape and symmetrically placed to facilitate installation and observation of diaphragms 4 and 5. Diaphragms 4 and 5 are identical in shape and size.

[0020] After the overall installation is completed, connect the output rod 13 to the drive device such as a motor. Then the output rod 13 rotates to pass the adhesive material into the glue inlet 8. When gear 6 and gear 7 rotate, the adhesive material is discharged from the glue outlet 9.

[0021] A protrusion 12 is fixedly connected to the inner wall of gear 6. One end of the output rod 13 passes through the metal part 16, metal plate 1, and diaphragm 4 in sequence and contacts the protrusion 12. A groove 14 is provided on the lower surface of the output rod 13. The groove 14 has the same shape as the protrusion 12. The protrusion 12 is inserted into the groove 14. When the output rod 13 rotates, the gear 6 can be driven to rotate through the protrusion 12. Diaphragm 4 and diaphragm 5 contact the upper and lower ends of gear 6 and gear 7, respectively. Diaphragm 4 and diaphragm 5 can prevent the adhesive material from contacting metal plate 1 and metal plate 3. A connecting rod 11 is sleeved on the inner wall of gear 7. The upper end of the connecting rod 11 passes through diaphragm 4 and is rotatably connected to metal plate 1. The lower end of the connecting rod 11 passes through diaphragm 5 and is rotatably connected to metal plate 3. At this time, gear 7 can rotate normally.

[0022] When the output rod 13 rotates, gear 6 starts to rotate. At the same time, gear 7 rotates synchronously. Under the meshing action of the teeth on their surfaces, the adhesive substance will flow from the side of the round hole to the outlet 9. Throughout the process, the adhesive raw material does not come into contact with metal plate 1 and metal plate 3.

[0023] The glue outlet 9 and glue inlet 8 pass through metal plate 3, diaphragm 5 and metal plate 2 in sequence and simultaneously contact gear 6 and gear 7. The glue material is discharged through gear 6 and gear 7. Several fixing bolts 10 are provided on the surface of metal plate 1. The threaded end of the fixing bolt 10 passes through metal plate 1, diaphragm 4, metal plate 2 and diaphragm 5 in sequence and is threadedly connected to metal plate 3. The whole can be fixed by fixing bolts 10.

[0024] In actual use, metal plate 1, diaphragm 4, metal plate 2, diaphragm 5 and metal plate 3 are installed in sequence and fixed with fixing bolts 10. Then, the output rod 13 is started and the adhesive material is introduced. At this time, the rotation of gear 6 and gear 7 can drive the adhesive material to be discharged. Diaphragm 4 and diaphragm 5 can prevent the adhesive material from contacting metal plate 1 and metal plate 3, thereby protecting them and improving the overall service life.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
