Description

Technical Field

[0001] The utility model relates to the technical field of pesticide packaging, in particular to a disc-type powder packaging device. Background Art

[0002] Generally, pesticides are in liquid and powder form. Powdered pesticides are called pesticide powders, which are used in agriculture to prevent and control pests and diseases, regulate plant growth, and kill weeds. In factories that produce pesticide powders, in order to quickly load them into packaging bottles or bags, powder packaging devices are generally used to quickly package the pesticide powders.

[0003] When the filling mechanism of the existing disc-type powder packaging device is in use, the distance between the discharge port of the filling mechanism and the packaging container is difficult to adjust, which easily causes the pesticide powder in the tank to fly, resulting in waste of pesticide powder. In addition, pesticide powder is toxic, so the scattered pesticide powder also poses a certain safety hazard to nearby workers. When the filling mechanism with a weighing device is discharging, the powder is easily blocked in the weighing device or part of the powder sticks to the inside of the weighing device, resulting in too slow a discharge speed or incomplete discharge, affecting packaging efficiency and packaging accuracy. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that the distance between the discharge port of the filling mechanism and the packaging container is difficult to adjust, and proposes a disc-type powder packaging device.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A disc-type powder packaging device includes a storage tank and a weighing assembly disposed at the storage tank discharge port. The weighing assembly includes a weighing tank and two weighing sensors. An extension assembly for adjusting the discharge height is disposed at the weighing tank discharge port. A vibrating mechanism is disposed on the surface of the weighing tank to vibrate the weighing tank.

[0007] The vibration mechanism comprises a striking component for striking the weighing tank to generate vibration and a rotating component for driving the striking component to rotate around the weighing tank.

[0008] In some embodiments, the extension assembly includes an extension tube slidably connected to the surface of the weighing tank discharge port, and a sealing plug is fixedly connected inside the extension tube for sealing the weighing tank discharge port. The sealing plug is conical, and the extension tube is driven to rise and fall by two driving push rods.

[0009] In some embodiments, the rotating assembly includes an annular slide fixedly connected to the surface of the weighing tank and a turntable rotatably connected to the surface of the weighing tank via the annular slide, and the turntable is driven to rotate by the driving assembly.

[0010] In some embodiments, the knocking assembly includes a connecting shaft fixedly connected to the lower surface of the turntable and a knocking rod rotatably connected to the lower surface of the turntable through the connecting shaft. The knocking rod is L-shaped, and a torsion spring is sleeved on the surface of the connecting shaft for rotating the knocking rod inward.

[0011] In some embodiments, a plurality of inclined blocks for driving the knocking rod to rotate outward are distributed in an array on the surface of the weighing tank.

[0012] In some embodiments, the surface of the weighing tank is provided with a reinforcement ring that thickens the knocking portion of the knocking rod.

[0013] In some embodiments, the weighing tank is mounted on the lower end of the storage tank discharge port, the two weighing sensors are fixedly connected to the surface of the weighing tank through two connectors, and the two weighing sensors are fixedly connected to the bottom of the storage tank.

[0014] In some embodiments, a stirring assembly is provided inside the storage tank to prevent powder clogging.

[0015] Compared with the prior art, the present invention provides a disc-type powder packaging device with the following beneficial effects.

[0016] 1. The utility model sets a rotating assembly so that the turntable drives the knocking assembly to rotate counterclockwise.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Reference Figure 1-5 A disc-type powder packaging device includes a storage tank 1 and a weighing assembly 2 arranged at the discharge port of the storage tank 1. The weighing assembly 2 includes a weighing tank 201 and two weighing sensors 203. The weighing tank 201 is sleeved at the lower end of the discharge port of the storage tank 1. Two connectors 202 are fixedly connected to the surface of the weighing tank 201. The two weighing sensors 203 are respectively fixedly connected to the upper surfaces of the two connectors 202. The two weighing sensors 203 are both fixedly connected to the bottom of the storage tank 1. The bottoms of the storage tank 1 and the weighing tank 201 are both conical. An electromagnetic valve is provided on the surface of the discharge port of the storage tank 1.

[0028] It can be understood that the discharge port of the storage tank 1 is opened by the solenoid valve, so that the powder falls into the weighing tank 201, and the powder in the weighing tank 201 is weighed by two weighing sensors 203. When the weight reaches the preset value, the solenoid valve is closed to achieve the purpose of precise quantity control.

[0029] Specifically, the discharge port of the weighing tank 201 is equipped with an extension assembly 3 for adjusting the discharge height. The extension assembly 3 includes an extension tube 301 that is slidably connected to the surface of the discharge port of the weighing tank 201. A sealing plug 302 is fixedly connected to the extension tube 301 to seal the discharge port of the weighing tank 201. The sealing plug 302 is made of rubber and has a conical shape. The extension tube 301 is driven up and down by two driving push rods. The ends of the driving push rods are respectively fixedly connected to the surfaces of the extension tube 301 and the weighing tank 201.

[0030] It can be understood that by driving the push rod to drive the extension tube 301 to slide on the surface of the discharge port of the weighing tank 201, it is convenient to adjust the distance between the extension tube 301 and the packaging container, so that the lower end of the extension tube 301 is deeply inserted into the packaging container for filling, thereby avoiding the powder from flying. By setting the sealing plug 302, the extension tube 301 drives the sealing plug 302 to move up and down, thereby facilitating the opening and closing of the discharge port of the weighing tank 201.

[0031] Specifically, the surface of the weighing tank 201 is rotatably connected to a rotating assembly 4, which includes an annular slide rail 401 fixedly connected to the surface of the weighing tank 201 and a turntable 402 rotatably connected to the surface of the weighing tank 201 through the annular slide rail 401. The turntable 402 is driven to rotate by a driving assembly 403. The driving assembly 403 includes a gear ring arranged on the surface of the turntable 402 and a gear meshing with the gear ring. The gear is fixedly connected to one end of the output shaft of the driving motor, and the driving motor is fixed to the side of the connecting body 202.

[0032] It can be understood that the gear is driven to rotate by the driving motor, and under the meshing relationship between the gear and the gear ring, the turntable 402 and the knocking component 5 are driven to rotate counterclockwise, so that the weighing tank 201 can be knocked around to improve the vibration effect.

[0033] A knocking assembly 5 for knocking the weighing tank 201 to generate vibration is provided on the lower surface of the turntable 402. The knocking assembly 5 includes a connecting shaft 501 fixedly connected to the lower surface of the turntable 402 and a knocking rod 502 rotatably connected to the lower surface of the turntable 402 through the connecting shaft 501. The knocking rod 502 is L-shaped, and a torsion spring 503 is sleeved on the surface of the connecting shaft 501 for rotating the knocking rod 502 inward. A plurality of inclined blocks 8 for driving the knocking rod 502 to rotate outward are distributed in an array on the surface of the weighing tank 201.

[0034] It can be understood that, in the process of the rotation of the knocking rod 502, when the upper end of the knocking rod 502 contacts the inclined block 8, the inclined block 8 pushes the knocking rod 502 to rotate on the surface of the connecting shaft 501, so that the lower end of the knocking rod 502 is away from the weighing tank 201, and the torsion spring 503 stores force. When the knocking rod 502 is separated from the inclined block 8, the torsion spring 503 drives the knocking rod 502 to knock on the weighing tank 201 to generate vibration, thereby increasing the discharge speed and avoiding incomplete discharge.

[0035] Specifically, a reinforcement ring 6 is provided on the surface of the weighing tank 201 to thicken the knocking portion of the knocking rod 502 .

[0036] It is understandable that, by providing the reinforcing ring 6 , it is prevented that the knocking rod 502 knocks the weighing tank 201 for a long time, causing pits or damage on the surface of the weighing tank 201 .

[0037] Specifically, a stirring assembly 7 is provided inside the storage tank 1 to prevent powder clogging. The stirring assembly 7 includes a stirring shaft 701 rotatably connected to the top of the storage tank 1 and a plurality of stirring rods 702 fixedly connected to the surface of the stirring shaft 701. The plurality of stirring rods 702 are fixedly connected to a scraper 703 at one end away from the stirring shaft 701. The scraper 703 overlaps the inner wall of the storage tank 1. There are two groups of scrapers 703, which are symmetrically arranged on the surface of the stirring shaft 701. The stirring shaft 701 is driven to rotate by a drive motor, and the drive motor is fixedly connected to the upper surface of the storage tank 1.

[0038] It is understandable that the stirring shaft 701 is driven to rotate by the driving motor, so that the stirring rod 702 and the scraper 703 rotate inside the storage tank 1, thereby preventing the powder from being blocked or sticking to the inner wall of the storage tank 1.

[0039] In the present invention, the stirring shaft 701 and the stirring rod 702 are driven by the driving motor to rotate inside the storage tank 1, so that the powder in the storage tank 1 falls into the weighing tank 201, and the weighing sensor 203 works. When the weight of the powder in the weighing tank 201 reaches the preset value, the solenoid valve closes the discharge port of the storage tank 1, and the extension tube 301 is driven to slide downward by the driving push rod, so that the lower end of the extension tube 301 is inserted into the packaging container. At the same time, the sealing plug 302 is driven to separate from the discharge port of the weighing tank 201, so that the powder in the weighing tank 201 is discharged into the packaging container. In the container, during the discharge process, the driving motor drives the gear to rotate, and under the meshing relationship between the gear and the gear ring, the turntable 402 is driven to rotate on the surface of the annular slide rail 401, thereby driving the knocking rod 502 to rotate. With the cooperation of multiple inclined blocks 8, the torsion spring 503 drives the knocking rod 502 to knock the reinforcement ring 6 multiple times to prevent the powder from being blocked in the weighing tank 201 or sticking to the inner wall of the weighing tank 201 and unable to be discharged. After the discharge is completed, the extension tube 301 and the sealing plug 302 are raised to seal the bottom of the weighing tank 201.
