Description

Technical Field

[0001] The utility model relates to the technical field of glue supply, in particular to a glue supply pump for quantitative feeding. Background Art

[0002] A glue pump is a device used to transport viscous substances such as glue and paint, and its working principle is based on the working principle of a pump. A glue pump usually consists of a pump body, a screw, a feed inlet, a discharge outlet, a transmission mechanism, etc. When the transmission mechanism is started, the screw begins to rotate, sucking the substance into the interior of the pump body from the feed inlet. As the screw rotates, the substance is pushed towards the discharge outlet and transported to downstream equipment.

[0003] When filling glue, it is necessary to ensure that the filling amount is the same, so a glue supply pump for quantitative feeding is required. However, due to the high viscosity of the glue, using a glue supply pump to pump the glue will result in an unstable flow rate. Therefore, using a flow sensor to quantitatively control the flow rate will result in inaccurate quantification.

[0004] For this reason, a glue supply pump for quantitative feeding is proposed. Content of the Utility Model

[0024] Such as Figures 1-4As shown in the figure, a glue supply pump for quantitative feeding includes a bottom plate 1. A weighing sensor 4 is provided at the top end of the bottom plate 1, and a quantitative tank 3 is provided at the top end of the weighing sensor 4. A feeding member 2 for feeding glue is provided on the bottom plate 1. The feeding member 2 includes a glue storage cylinder 201 provided at the top end of the bottom plate 1 and a glue supply pump body 202 provided at the top end of the glue storage cylinder 201. The output end of the glue supply pump body 202 is connected to a second connecting pipe 204. An inlet pipe 5 is provided inside the quantitative tank 3, and an inlet hole 501 is provided on the inlet pipe 5. The second connecting pipe 204 extends into the interior of the inlet pipe 5. A blanking member 6 for squeezing and pushing the glue for blanking is provided inside the quantitative tank 3. The blanking member 6 includes a motor 601 provided at the top end inside the quantitative tank 3, a threaded sleeve 603 rotatably provided at the top end inside the quantitative tank 3, and a pushing scraper 606 slidably provided inside the quantitative tank 3. A hollow threaded cylinder 604 is threadedly connected inside the threaded sleeve 603. Specifically, the provided weighing sensor 4 can detect the weight of the glue entering the interior of the quantitative tank 3. When it detects that the weight of the glue inside reaches the set value, it will send a signal to an external controller, and the controller will control the feeding member 2 to stop feeding glue into the quantitative tank 3, thereby ensuring the quantitative supply of glue. When discharging the glue, the provided blanking member 6 can squeeze and push the glue inside the quantitative tank 3, so that the glue inside the quantitative tank 3 can be completely discharged.

[0025] As Figure 1 and 3 shown in the figure, four support rollers 101 are provided at the bottom end of the bottom plate 1, and a through hole 102 is provided on the bottom plate 1. Specifically, the provided support rollers 101 can facilitate the movement of the position of the supply pump.

[0026] As Figure 3 shown in the figure, the input end of the glue supply pump body 202 is connected to a first connecting pipe 203. One end of the first connecting pipe 203 extends into the interior of the glue storage cylinder 201, and the second connecting pipe 204 is slidably connected to the inlet pipe 5. Specifically, when the glue supply pump body 202 works, it can pump the glue inside the glue storage cylinder 201 into the interior of the inlet pipe 5, and then the glue can enter the interior of the quantitative tank 3 through the inlet hole 501.

[0027] As Figure 3 shown in the figure, a discharge pipe 301 is provided on the quantitative tank 3, and a valve 302 is provided on the discharge pipe 301. The position of the through hole 102 corresponds to that of the discharge pipe 301. Specifically, through the discharge pipe 301, it is convenient to discharge the quantitative glue.

[0028] As Figure 4As shown, a first gear 602 is connected to the spindle end of the motor 601. A second gear 605 that meshes with the first gear 602 is sleeved on the threaded sleeve 603, and the material pushing scraper 606 is connected to the hollow threaded cylinder 604. Specifically, when the motor 601 operates, it can drive the first gear 602 to rotate. Since the first gear 602 meshes with the second gear 605, it can drive the threaded sleeve 603 to rotate. When the threaded sleeve 603 rotates, it can drive the material pushing scraper 606 to move up and down. When it moves down, it can push the glue inside the metering tank 3 downward and push it out.

[0029] As Figure 2 shown, two telescopic rods 7 are provided at the inner top of the metering tank 3, and the material pushing scraper 606 is connected to the telescopic ends of the telescopic rods 7. Specifically, the provided telescopic rods 7 can limit the material pushing scraper 606 and prevent it from rotating.

[0030] In summary, the provided weighing sensor 4 can detect the weight of the glue entering the metering tank 3. When it detects that the weight of the glue inside reaches the set value, it will send a signal to the external controller, and the controller will control the feeding component 2 to stop feeding the glue into the metering tank 3, thereby ensuring the quantitative supply of the glue. When discharging the glue, the provided discharging component 6 can extrude and push the glue inside the metering tank 3, so that the glue inside the metering tank 3 can be completely extruded.
