Description

Technical Field

[0001] The invention relates to the technical field of gear pumps, in particular to a glue injection gear pump used for intelligent industrial production. Background Art

[0002] The 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 liquid or increase its pressure. It consists of two closed spaces formed by two gears, a pump body, and front and rear covers. When the gears rotate, the volume of the space on the side where the gears are disengaged changes from small to large, forming a vacuum, sucking the liquid in, and the volume of the space on the side where the gears are meshing changes from large to small, squeezing the liquid into the pipeline. After the liquid enters the discharge chamber, the teeth of the two gears are constantly meshing, so that the liquid is squeezed from the discharge chamber into the discharge pipe, so that the gear pump can continuously inhale and discharge the liquid. The suction chamber and the discharge chamber are separated by the meshing line of the two gears. The pressure of the discharge port of the gear pump depends entirely on the size of the resistance at the pump outlet.

[0003] The patent application with publication number CN117703748A discloses a gear pump and a gear pump housing, the inner wall of which has an area that matches the gear, and the radial clearance between the area and the corresponding matching gear along the rotation direction of the gear tends to gradually increase. The contour line corresponding to the third area is a third arc line, and the third arc line is equal in diameter to the first arc line, and the center of the third arc line is relative to the center of the cross section of the corresponding gear at the inner wall, along the direction of the line connecting the center of the gear pair cross section, and is eccentrically arranged to the liquid outlet side. During the rotation of the gear in the gear pump housing, the bubbles can be gradually and slowly released while maintaining normal liquid suction, so that when the bubbles enter the discharge chamber of the gear pump, they can adapt to the pressure of the discharge chamber without suddenly bursting and producing noise.

[0004] However, the gear pump disclosed above has a complex structure, a cumbersome installation process, is time-consuming and laborious, and cannot quickly disassemble the shell. Moreover, after long-term use, some residues will adhere to the inner wall of the discharge port, which will affect subsequent use after long-term use, and lacks a linkage scraping structure.

A swing arm 24 is also fixedly provided on the top of the moving shaft 21; a traveling gear 25 meshing with the ring gear 23 is movably installed on the swing arm 24; a lifting arm 26 is movably provided on the top of the traveling gear 25, and the connection between the lifting arm 26 and the traveling gear 25 is coaxial with the linkage shaft 21; the lifting arms 26 on both sides pass through the meshing bin 22, and a linkage arm 28 is installed between the outer sides of the lifting arms 26, and a moving discharge nozzle 29 that fits with the inner wall of the fixed discharge nozzle 12 is provided in the middle of the linkage arm 28; a notch portion 31 is also provided at the bottom of the side cover 18, and a power bin 32 is also provided at the bottom of the pump body 1 and the pump body 2.

[0036] In this embodiment: the injection gear pump for intelligent industrial production is mainly divided into three parts: pump body 1, pump body 2 and power chamber 32. When the device is in use, the feed port 13 is first connected to the external glue supply device, and then the motor 35 is started.

[0043] See attached Figure 2 and attached Figure 6 On both sides of the linkage wheel 1 3 are arranged upper rotating shafts 5 penetrating through the pump body 1 and the pump body 2 2 , and the upper rotating shafts 5 are connected to the linkage shaft 21 through a belt 42 .

[0044] In this embodiment, when the linkage wheel 3 rotates, a belt 42 structure is designed to synchronously drive the linkage shaft 21 to rotate, thereby driving the moving discharge nozzle 29 to reciprocate.

[0045] See attached Figure 8 -Attached Fig. 9 A lower rotating shaft 6 penetrating through the pump body 1 and the pump body 2 2 is arranged on both sides of the linkage wheel 2 4, and a driven gear 36 located in the side cover 18 is installed on both sides of the lower rotating shaft 6; a motor 35 is installed on the side of the power compartment 32, and a driving gear 37 meshing with the driven gear 36 is installed at the output end of the motor 35.

[0046] In this embodiment: when the motor 35 drives the driven gears 36 on both sides to rotate through the driving gear 37, the linkage wheel 2 4 will drive the linkage wheel 1 3 to rotate and realize the industrial injection of glue.

[0047] See attached Figure 1 -Attached Figure 4 A threaded ring 14 is threadedly mounted on the fixed discharge nozzle 12 , and a threaded ring 2 15 is threadedly mounted on the feed port 13 .

[0048] In this embodiment, since the fixed discharge nozzle 12 and the feed port 13 on the pump body 1 and the pump body 2 are both semi-ring structures, in order to quickly lock them, a threaded ring 14 and a threaded ring 2 15 are designed.

[0049] See attached Figure 1 -Attached Figure 2 Screw holes 19 are also provided on the outer walls of the pump body 1 and the pump body 2, and the side cover 18 is installed on the outer sides of the pump body 1 and the pump body 2 by bolts 20; a mounting cover 41 is also provided on the outer side of the meshing chamber 22.

[0050] In this embodiment, the bolt 20 structure is designed for quick installation of the side cover 18. In order to facilitate disassembly and assembly and observe the internal conditions of the inspection and repair meshing chamber 22, a mounting cover 41 structure is designed.

[0051] See attached Fig. 9 -Attached Fig.11 A plug plate 38 is provided on the inner wall of the notch portion 31 , and a groove 39 matching with the plug plate 38 is provided on the top of the power compartment 32 , and the plug plate 38 and the groove 39 are connected by a second screw 40 .

[0052] In this embodiment, in order to further facilitate the maintenance of the drive device, a detachable power compartment 32 is designed. In order to quickly disassemble and fix the power compartment 32, a plug plate 38 and a groove 39 structure that cooperate with each other are provided.

[0053] See attached Fig.10 -Attached Fig.12 An engagement groove 27 cooperating with the lifting arm 26 is provided on the inner wall of the engagement bin 22, and the engagement groove 27 is located above the gear ring 23; a scraping portion 30 is provided at the bottom of the moving discharge nozzle 29, and the linkage shaft 21 is rotatably arranged on the outer wall of the pump body 1 and the pump body 2 2 through a bearing 43.

[0054] In this embodiment: in order to ensure that the lifting arm 26 reciprocates horizontally along the meshing bin 22, an engagement groove 27 structure is provided. In order to prevent glue from adhering to the inner wall of the fixed discharge nozzle 12, thereby affecting subsequent use, a scraping portion 30 is designed. When the moving discharge nozzle 29 reciprocates along the fixed discharge nozzle 12, the scraping portion 30 can efficiently clean its inner wall.

[0055] Working principle of the present invention: When the device is in use, first connect the feed port 13 to the external glue supply device, and then start the motor 35. When the motor 35 drives the driving gear 37 to rotate, it will drive the driven gears 36 on both sides of the lower rotating shaft 6 to rotate. At this time, the linkage wheel 24 will drive the linkage wheel 13 to rotate and realize the industrial injection of glue. When the upper rotating shaft 5 drives the linkage shaft 21 to rotate through the belt 42, the travel gear 25 will rotate along the ring gear 23. Since the diameter of the travel gear 25 is half the diameter of the ring gear 23, and the connection between the lifting arm 26 and the travel gear 25 is coaxial with the linkage shaft 21, when the travel gear 25 rotates, the lifting arm 26 will drive the moving discharge nozzle 29 to reciprocate along the fixed discharge nozzle 12. The scraping part 30 will scrape the inner wall of the fixed discharge nozzle 12 back and forth to avoid glue residue, which further improves the cleaning effect.
