Description

[0002] In the field of modern industry, fluid transportation and power transmission are crucial links, and gear pump, as a common fluid transportation equipment, has a long history of development and a wide range of application scenarios. The working principle of gear pump is based on the meshing movement of gears. By rotating the gears that mesh with each other in the pump body, an oil suction cavity and an oil pressure cavity are formed, thereby realizing the suction and discharge of liquid. The gear pump is driven by an independent motor, which can effectively block the pressure pulsation and flow fluctuation of the upstream. In the production of gear pump, it is necessary to inject glue into the gear pump itself. The existing glue injection machine still needs to be held and placed at the glue outlet of the glue injection machine to wait for the glue to be taken out after the glue is discharged. Not only is the efficiency low, but also it is extremely labor-intensive. For large quantities of gear pumps, the glue injection efficiency cannot meet the requirements, which affects the production time and increases the production cost. SUMMARY

[0023] Furthermore, the feeding tray 34 includes a placement plate 341. The outer wall of the placement plate 341 is fixed to the inner wall of the left threaded sleeve 316 and the right threaded sleeve 334 respectively.

[0025] As a further improvement of the present invention, the pushing component 5 includes a pushing rod 51. The front and rear ends of the pushing rod 51 are fixed to the front and rear walls inside the right side groove 12. A sleeve block 52 is sleeved in the center of the pushing rod 51. The left side of the sleeve block 52 is connected to the pushing plate 53. The bottom side of the pushing plate 53 contacts the top side of the moving component 4 located inside the feeding port 11, so as to push the gear pump that needs to be injected into the main lifting component for convenient positioning and time saving.

[0026] Furthermore, the pull assembly 6 includes a side rail 61, the left wall of which is fixed to the right wall of the left side groove 14. A sliding groove 62 is opened at the top right side of the side rail 61, and a sliding block 63 is locked inside the sliding groove 62. The right side of the sliding block 63 is connected to a pull plate 64, and a pull rod 65 is fixed at the front right side of the pull plate 64. Pulling out the pull plate allows the gear pump to be removed for easy operation.

[0027] Working principle: During operation, when the gear pump needs to inject glue, simply place the gear pump inside the feeding port 11 on the first roller 42 connected to the left horizontal plate 41. Then, push the push plate 53 so that the sleeve block 52 fixed on the right can slide inside the push rod 51 to improve the stability of movement. When the push plate 53 pushes the gear pump to the top of the multiple sets of second rollers 343 fixed on the right side of the feeding tray 34 in the main lifting assembly 31, the servo motor 311 is then started to drive the main threaded rod 313 at the top to rotate. The main threaded rod 313 rotates through the main limiting sleeve 314 at the top, which drives the left threaded sleeve 316 to rise. The rise of the left threaded sleeve 316 drives the right threaded sleeve 316 to rise. The side-fixed placement plate 341 and the lifting block 352 fixed at the front end of the placement plate 341 slide and rise within the column 351. When the main threaded rod 313 rotates, the left sleeve post 315 fixed at the top of the main threaded rod 313 drives the fixed left chain assembly 321 to rotate synchronously. The rotation of the left chain assembly 321 simultaneously drives the first rotating shaft 322 fixed at the rear to rotate. The first rotating shaft 322 rotates synchronously with the second rotating shaft 324 connected to the right side via a transmission belt assembly 323 at the bottom. The second rotating shaft 324 rotates under the rotation of the bottom transmission belt assembly 323, thereby driving the first gear 325 fixed at the center to rotate. The first gear 325 meshes with the second gear 326 on the right side. Reverse rotation of the second gear 326 drives the fixed third rotating shaft 327 to rotate. The third rotating shaft 327, when rotating, synchronously reverses through the right chain assembly 328 at the top, causing the front auxiliary threaded rod 331 to reverse under the rotation of the right chain assembly 328 connected to the top right sleeve post 332. When the auxiliary threaded rod 331 reverses within the auxiliary limiting sleeves 333 at both ends, it drives the right threaded sleeve 334, causing the fixedly connected right-side feeding tray 34 to descend. Once the main lifting assembly 31 raises the feeding tray 34 and gear pump to the preset position, the pusher 71 is activated, using the front-mounted L-shaped push plate 72 to push the gear pump onto the dispensing plate 23 for further use. The glue dispensing machine 8 dispenses glue. Simultaneously, the servo motor 311 is activated in reverse to lower the main lifting assembly 31. As the main lifting assembly 31 descends, it is driven by the transmission assembly 32 to raise the auxiliary lifting mechanism 33. When the auxiliary lifting mechanism 33 reaches the preset position, the glue dispensing ends. The pusher 71 then pushes the gear pump onto the feeding tray 34 at the left end of the auxiliary lifting mechanism 33. The pusher 71 then drives the L-shaped pusher plate 72 back to its original position. The next set of gear pumps can then be pushed onto the feeding tray 33 connected to the main lifting assembly 31 using the same operation. The servo motor 311 is then activated again to raise and lower the gear pumps. As the main lifting assembly 31 rises, the auxiliary lifting assembly 33 descends under the transmission of the transmission assembly 32.Pulling the lever 65 on the right side will extend the fixed pull plate 64 on the left side, allowing the gear pump to be pulled out through the moving component 4 at the discharge port 13 on the right side.
