Description

Technical Field

[0001] The utility model relates to an automatic weighing device, in particular to an automatic medicine weighing machine for gas generators. Background Art

[0002] During the production process of gas generators, it is necessary to separately package and weigh the ignition medicine of the gas generators to ensure that the ignition medicine filled into the ignition medicine cartridges of the gas generators meets the requirements of the filling amount. The filling amount of the ignition medicine of the gas generator will affect the ignition ability of the product. If the filling amount of the ignition medicine is unqualified, it will affect the ignition of the gas generator, resulting in the gas generator being unable to work properly, and thus losing the function of protecting the occupants. At present, the separate packaging and weighing of the ignition medicine of gas generators rely on manual weighing, which not only has low weighing efficiency and is prone to unqualified weighing phenomena, but also has a large labor intensity. Therefore, in order to solve the consistency of the separate packaging and weighing of the ignition medicine of gas generators, it is necessary to design mechanical equipment for automatic separate packaging and weighing of the ignition medicine, reduce the manual labor intensity, and improve the production efficiency.

An electronic balance 13 is fixedly installed at the upper end of the balance support 11, and a protective cover 12 is buckled outside the electronic balance 13. A weighing funnel 16 is connected to the weighing end of the electronic balance 13. The weighing funnel 16 is a split and openable structure and is used to receive the ignition medicine conveyed through the first linear vibration track 9. The weighing funnel 16 is formed by inserting and hinging two triangular guiding grooves. A U-shaped hanging bracket 15 is sleeved on the hinge shafts at both ends of the weighing funnel 16 to facilitate connecting to the weighing end of the electronic balance 13.

[0026] A liftable opening and closing baffle 18 is provided near the weighing funnel 16 on the balance support 11 for controlling the opening and closing of the weighing funnel 16. An opening and closing cylinder 17 is fixed on the balance support 11, and the opening and closing baffle 18 is connected to the lower end of the piston rod of the opening and closing cylinder 17 to control the lifting of the opening and closing baffle 18. When the opening and closing baffle 18 rises, it can drive the material guiding groove on one side of the weighing funnel 16 to turn up, thereby opening the weighing funnel 16.

[0027] A support plate 25 is provided in the middle of the balance support 11. A waste box base 21 and a funnel support 22 are fixed on the support plate 25. A waste box 20 is supported on the waste box base 21, and a pre-installed funnel 31 is fixed on the funnel support 22; the waste box 20 and the pre-installed funnel 31 are arranged side by side and have flush tops. A horizontally arranged sorting cylinder 14 is fixed on the upper part of the balance support 11. A laterally movable sorting funnel 19 is connected to the front end of the piston rod of the sorting cylinder 14. The sorting funnel 19 is located below the weighing funnel 16, and when it moves to both ends, the discharge ports at the lower ends of the sorting funnel 19 respectively correspond to the upper openings of the waste box 20 and the pre-installed funnel 31, for guiding the ignition charge in the weighing funnel 16 into the waste box or the pre-installed funnel 31.

[0028] A discharge baffle 24 is hinged to one side of the outlet at the lower end of the pre-installed funnel 31. A discharge cylinder 23 is provided between one side of the pre-installed funnel 31 and the discharge baffle 24. The cylinder bodies and piston rods at both ends of the discharge cylinder 23 are respectively hinged to the upper end of one side of the pre-installed funnel 31 and the outer end of the discharge baffle 24 for controlling the flipping and discharging of the discharge baffle 24.

[0029] A support plate 29 is fixed on the weighing platform and a medicine cup 28 is placed thereon for receiving the ignition charge discharged from the pre-installed funnel 31.

[0030] A vertically arranged funnel cylinder 26 is fixed under the support plate 25 through a mounting plate frame 27. The lower end of the piston rod of the funnel cylinder 26 is fixedly connected with a material guiding funnel 30. The material guiding funnel 30 is located below the outlet of the pre-installed funnel 31 to accurately guide the ignition charge into the medicine cup 28.

[0031] The medicine weighing machine is also provided with a controller and a human-machine interface (not shown in the figure). The controller is a PLC programmable controller. The signal output end of the electronic balance 13 is communicatively connected to the controller for controlling the actions of each cylinder and the linear vibrator according to the weighing amount and performing parameter settings.

[0032] During operation, start the device power switch to power on the device. Add a certain amount of ignition charge to the hopper and the vibrating disk 6, place the medicine cup on the support plate, and set various parameters for weighing the ignition charge in this production on the human-machine interface.

[0033] When the start switch is turned on, the vibrating disk 6 starts to vibrate. The ignition charge is vibrated by the vibrating disk 6 and arranged in a row to enter the first linear vibrating track 9 through the discharge chute rail. Under the vibration of the linear vibrator 10, the ignition charge grains enter the weighing funnel 16 and are weighed by the electronic balance 13. When the ignition charge weighed by the electronic balance 13 reaches the set value, the linear vibrator 10 and the vibrating disk 6 are controlled by the controller to stop working. At the same time, the linear vibrator 3 starts to work. After a certain amount of ignition charge is replenished into the vibrating disk 6 through the second linear vibrating track 4, the linear vibrator 3 stops working. If the weighed ignition charge is within the range set by the set value, the opening and closing cylinder 17 is controlled by the controller to contract, so that the weighing funnel 16 is opened, and the ignition charge enters the preloading funnel 31 through the sorting funnel, and then the opening and closing cylinder 17 resets and extends. If the weighed ignition charge exceeds the range set by the set value, the sorting cylinder 14 contracts, driving the sorting funnel 19 to move above the waste box. The opening and closing cylinder 17 is controlled by the controller to contract, opening the weighing funnel 16, so that the ignition charge enters the waste box through the sorting funnel, and then the opening and closing cylinder 17 resets and extends, and the sorting cylinder 14 resets and extends.

[0034] When the ignition charge enters the preloading funnel 31, the discharging cylinder 23 is controlled by the controller to contract, driving the discharging baffle 24 to rotate counterclockwise to open the outlet at the lower end of the preloading funnel 31. The ignition charge enters the medicine cup through the guiding funnel. The discharging cylinder 23 resets and extends, and the operator takes out the medicine cup to complete a working cycle.
